The proposal includes the construction of a new community recreation center and new outdoor recreational facilities, including a swimming pool, pickleball courts, skate plaza, basketball court, outdoor game area, and seasonal ice rink. The proposal requires the following zoning approvals: 1) final plat of subdivision; 2) final PUD; 3) variation from the exterior yard setback requirement; and 4) a development code exception. The proposal meets the requirements and standards of the Village Code, and Village Staff ("Staff") is supportive of the requests. Discussion BACKGROUND / PROPERTY HISTORY The subject property, Lions Memorial Park, is an existing 20.8-acre community park bounded by Maple Street to the west, Lincoln Street to the north, William Street to the east, and Sha Bonee Trail / Lions Park Elementary School to the south. The park was established in 1955 and contains a recreation center, parking lot, and outdoor recreational amenities including a swimming pool, bandshell, tennis courts, ball fields, playground, and walking paths. The recreation center was constructed in 1970, the swimming pool was constructed in 1984, and the bandshell was constructed in 1999. Phase 1 updates to the park were completed in 2024 including the new playground, new walking paths, and re -surfaced tennis courts. In November 2024, voters approved a $46.2 million bond referendum to fund Phase 2 of the park renovation, with 64.5% voting in favor. d:T61161-1_10 The petitioner, Studio 222 Architects LLC, on behalf of the property owner, Mt Prospect Park District, is proposing to demolish the existing recreation center and swimming pool, and to construct a new recreation center and swimming pool, including a splash pad, water slides, bath house, and pool equipment building. The petitioner is proposing new outdoor recreational amenities including a skate plaza, basketball court, six pickleball courts, outdoor game area, and seasonal ice rink. Site Plan: The northwest side of the park contains most of the site improvements, while the southwest and east side of the park are predominantly open green space. The park amenities are connected to each other via asphalt walking paths that link to neighborhood sidewalks and the parking lot. The petitioner notes that one of the goals of the site design is to provide direct access from the parking lot to the band shell and other outdoor amenities without having to circulate around the entire building, as with the current facility. The overall lot coverage of the subject property will increase to 33%, which is below the maximum allowable lot coverage of 75%. The proposed recreation center is set back 10.17' from Lincoln Street, whereas the underlying zoning district (C-R) requires a minimum setback of 30' for the exterior side yard. The petitioner is requesting a variation from the exterior side yard setback requirements. Staff agrees that the parcel shape and position of existing amenities pose a unique challenge when siting the recreation center, and concurs that the setback requirement would pose a hardship for the park district to create a practical site plan. Staff notes that the existing facility already has a non -conforming setback (17.85') and does not believe that reducing the setback to 10.17' will alter the essential character of the neighborhood. Staff supports the variation request and finds that it is consistent with the overall goals of the PUD. Recreation Center: The new two-story recreation center will be 42' tall and have 55,700 square feet with a gymnasium, walking track, dance studio, multi -generational room, multi- purpose rooms, art studio, and preschool room. The main entry will be located on the west elevation, and will feature a metal canopy. The fagade will be constructed of precast concrete panels with various finishes, including Norman -sized cast brick. Design elements will include cast stone coping, woodgrain-finish metal panels, and a prefinished aluminum curtain wall system. The refuse enclosure and loading dock will be located on the northeast elevation and will be screened with a six-foot tall solid panel sliding gate. Swimming Pool: The swimming pool area consists of a bathhouse (5,352 SF), pool equipment building (1,304 SF), leisure pool with water slides (11,878 SF), splash pad (2,960 SF), and pool deck (22,480 SF). The maximum height of the water slide structure will be 31', measured at the top of the platform canopy. The bathhouse and the pool equipment building facades will be consistent with the materials featured on the recreation building, and will measure 19.66' and 16.33' in height, respectively. Other Amenities: Six pickle ball courts will be installed to the east of the existing tennis courts, and will feature fencing and wind screens similar to the tennis courts. The skate park and basketball court will be located east of the playground. The petitioner noted in their application that the skate park and basketball court locations were chosen because of existing site grading and to maintain open space in the center of the park for programming. The seasonal ice rink will be located south of the recreation center and will be a "flood -type" sheet of ice with a liner and 2x trim board edging. Hours of Operation: The document titled "Lions Memorial Park Land Use Table" dated July 17, 2025 (see Exhibit 6) details the hours of operation and outdoor lighting for the current and proposed amenities. The time range represents the earliest and latest times proposed for each amenity, though it is not expected that every amenity will operate every day for the entire operating window. The recreation center is proposed to operate 6AM to 11PM year-round. The pool is proposed to operate 6AM to 9PM during the summer season, however, the pool will be closed when events take place at the bandshell. The bandshell is proposed to operate between 7AM to 10PM during the summer season. Outdoor sports courts with lighting are proposed to operate between 7AM to 10PM, seasonally. Outdoor amenities without lighting are proposed to operate from dawn to dusk. Parking: The petitioner provided a parking study to estimate parking demand for the site using various methods. Overall site occupancy is increasing by approximately 13%, not considering seasonality and scheduling. The existing uses require approximately 800 parking stalls according to code, yet the subject property currently contains 179 parking stalls on site. As with the existing conditions, the proposal will also be short on code -required parking. However, the Mt. Prospect Park District does not operate all uses at the same time, and is working with Staff to provide a Special Event Parking Management Plan, is pursuing parking agreements with adjacent and nearby property owners, and has committed to a review of actual parking impacts once the facility opens. Parking Supply The petitioner is proposing to add 21 parking stalls to the existing parking lot, increasing the total from 179 to 200 parking stalls (approximately 12% increase). The parking study included a parking survey that assessed the parking available on weekdays and weekends in the Lions Park Elementary School Parking Lot (up to 93 spaces) and Maple Street Parking Deck (up to 262 spaces). The Mt. Prospect Park District is exploring off-street parking agreements with Dason Community Church (30-50 spaces) and Busse Automotive (50-75 spaces). The parking study also documented on -street parking around the site, estimating 715 on -street parking spots available on a weekday after 4PM. Staff is encouraging that off-street parking options are explored before resorting to on -street parking. The study included parking supply information from three Arlington Park District properties (Recreation, Camelot, and Frontier) which have maximum occupancy capacities ranging from 1,608 to 1,844 people and on -site parking provided ranging from 72 to 93 parking spaces. In comparison, Lions Memorial Park proposed capacity is 1,990 and will have 200 on -site parking spaces, more than double those other area facilities. Parking Demand The zoning code requires a minimum number of off-street parking spaces based square footage and occupancy for each use. The study suggests 1,070 off-street parking spaces are required for the site according to the zoning code. Staff notes that the zoning code allows for reduced off-street parking in B-5 and B-5C Central Commercial zoning districts - generally 50% of the parking required in other districts. 50% of the minimum parking requirement would be 535 parking spaces. The parking study provided an estimate of parking demand based on the Institute of Transportation Engineers (ITE) data and local data, which suggested that peak demand would be 553 vehicles, or 55% of the zoning code minimum. The Mt. Prospect Park District provided estimates of actual park activities taking place across the seasons, by time of day, versus maximum activity. Using this method, the park district estimates demand to range from 154 vehicles on the low end, to 612 vehicles during a Thursday concert at the bandshell. It shows that on a normal, non -concert day during the summer, parking demand will be roughly 250 vehicles. Based on the 200 stalls to be provided on site, along with the additional parking available in the Maple Street Parking Deck, on -street parking, and potential to secure parking agreements with nearby properties, Staff supports the proposed parking plan. Should the site experience regular overflow with a need for additional parking, the petitioner identified two locations on Lincoln and Maple Streets where angled parking could be added in the public right-of-way adjacent to Lions Memorial Park. Staff is willing to explore this option should the need arise. Landscaping: New landscaping is proposed throughout the site to complement the new buildings, enhance the parking lot, and provide limited screening for certain recreational areas, all while prioritizing an open viewshed into the expansive green space. Areas with notable new plantings include robust foundation plantings on the north fagade of the recreation center; shade trees for the parking lot islands; evergreen screening on the west side of the tennis courts and south side of the skate park and basketball court; and water - tolerant species around and within the naturalized storm basin. Given the expansive green space provided within the park itself, the intent of the landscape code is met through the overall design, making the full extent of traditional commercial perimeter landscaping unnecessary. Lighting: The petitioner provided a photometric site plan with new wall mounted lights for the recreation center and pool buildings; illuminated bollards for the walking paths near the recreation center; uplights for the flag pole; and pole -mounted lights for the parking lot. The baseball fields and tennis courts are already equipped with sports lighting, and the petitioner is proposing similar sports lighting for the pickleball courts, pool area, and seasonal ice rink. A fully compliant photometric plan will be required as part of building permit submittal. Signage: The petitioner intends to replace the freestanding sign at the entrance of the park, containing carved letters and the park district logo on a single -sided plastic surface. The recreation center features an 8' diameter park district logo. The bath house features walls signs identifying the different entryways (aquatics, concessions, guards, first aid). The PUD will approve signage consistent with what is submitted, and any future relief requested for signage shall require an application for a minor amendment to the PUD. Stormwater: The subject property has an existing detention area east of the playground and the petitioner is proposing an additional detention area on the east side of the site near William Street. With a new building being constructed on site, the development code requires that stormwater detention be provided for the entire site. However, the petitioner is proposing to provide detention only for the areas being disturbed for this project. The petitioner contends that detaining the stormwater for the entirety of the subject property would require an unreasonable amount of space and have a detrimental impact on the park and its ability to function, especially for events, due to the substantial increase in area required for detention. Therefore, the petitioner is requesting an exception from the development code. Staff supports this development code exception due to the size and scale of the park. With grass areas that would remain undisturbed, including the ball fields, requiring additional detention is impractical and detrimental to the project. Phasing: The petitioner is pursuing project design, permitting, and bidding throughout the summer and fall of 2025. If the proposal is approved by the Village Board, the petitioner will seek Mt. Prospect Park District Board approval in October 2025. Demolition of the pool and recreation center is anticipated for October / November 2025, with substantial completion of Phase 2 expected in May 2027. ZONING REQUESTS The proposal requires the following zoning approvals: • Final Plat of Subdivision (15.304): The subject property is comprised of two parcels totaling 20.8 acres. The parcels will be consolidated into one lot of record and utility easements will be granted over existing Village storm and combined sewers crossing the site. • Final Planned Unit Development (PUD) (14.503.C): A Planned Unit Development (PUD) is required because multiple buildings and accessory structures are proposed for one zoning lot. PUDs provide a tool to accommodate development which is in the public interest, provides a public benefit, and which would not otherwise be permitted by the zoning ordinance. • Variation from Exterior Yard Setback (14.504.C.5.a): The proposed recreation center is set back 10.17' from Lincoln Street, whereas the underlying zoning district (C- R) requires a minimum setback of 30' for the exterior side yard. The petitioner is requesting a variation from the exterior side yard setback requirements. • Development Code Exception (15.401.13 and 15.402.13): The development code requires that the entire site be brought into compliance with current stormwater management standards when a new building is constructed. The petitioner is requesting a development code exception to provide stormwater detention only for the areas to be disturbed as part of this project. ADDITIONAL CONSIDERATIONS When a unit of local government, such as a school district, park district, or county, comes to the Village with a zoning request, the Village's Planning & Zoning Commission and Board of Trustees apply the same standards from the zoning ordinance to the zoning application as it would with a private property owner. However, in addition to the standards in the zoning ordinance, the Planning & Zoning Commission and Board of Trustees need to consider whether any condition of approval or whether a denial of the application would thwart or frustrate the unit of local government's statutory duties. Stated positively, the Village should consider whether the requested relief furthers the statutory mission of the unit of local government and, if it does, give the requested relief some deference. Standards and Findings: Staff finds that the proposal will update aging public facilities and bring new recreation amenities to an existing community park, thereby supporting public health and general welfare of the community. The petitioner has considered the impact on the neighborhood and solicited community input on the project over the course of two years. Staff has recommended conditions of approval to address potential adverse impacts, such as landscape screening, parking management plans, and guidelines for hours of operation. Based on the information submitted, the surrounding uses, and the proposed development's compliance with the Village's zoning ordinance and long-range planning documents, Staff supports the petitioner's zoning requests. Public Comment: The Village received one written request to fill the sidewalk gaps on Maple and Lincoln Streets. Public Hearing: At the public hearing held on August 14, 2025, the Planning and Zoning Commission asked about the sidewalk gaps on Maple and Lincoln Street adjacent to the parking lot. The petitioner stated that the gaps will not be filled in these areas due to steep grading that would prohibit installation of an ADA-compliant public walk. The Commission discussed the setback of the recreation building from Lincoln Street. The petitioner explained that the size of the building is dictated by the desired programming and the position of the building is optimal given the constraints of the site and the desire to provide a generous path from the parking lot to the bandshell. The petitioner noted that they provided abundant foundation landscaping and architectural interest to the north facade to compensate for the reduced setback of the building. The Commission asked about the height of the building and screening of RTUs. The petitioner stated that the predominant height of the parapet is 36' but portions of the building that are set back farther from the street measure 42' to the parapet. The petitioner confirmed that the RTUs will be screened by the parapet. The Commission inquired if there were issues with flooding in the neighborhood or on the site. The petitioner shared that the site currently has no significant stormwater management and that the project will provide notable watershed benefits for the local sewers. The Commission asked if the site will have enough parking for all the new amenities. The petitioner replied that yes, sufficient parking is available with a combination of onsite parking, offsite parking at local parking lots and garages, and on -street parking adjacent to the park. The Planning and Zoning Commission unanimously recommended approval of the requests by a vote of 7-0. No members of the public were present to voice support or opposition. Revisions: Staff updated the conditions of approval for the plat of subdivision based on a revised plat dated August 21, 2025, and attached as part of the agenda packet. Staff revised the text for the variation from 10.2' to 10.17' to reflect the proposed setback measurement to the nearest hundredths of a foot. Petitioner Requests: The petitioner submitted a letter requesting that the Village Board waive the second reading of the ordinance and take final action at the September 2, 2025 meeting. Village fees for the proposal include platting ($500), zoning requests ($3,000), code exception ($250), building permit ($438,148), site development ($185,505), and parkway trees ($300 per tree). Mt. Prospect Park District respectfully requests that all non-refundable Village fees be waived for the upcoming construction project. AItarnnfivaq A. Approval of the following motions: 1.

The park was established in 1955 and contains a recreation center, parking lot, and outdoor recreational amenities including a swimming pool, bandshell, tennis courts, ball fields, playground, and walking paths. The recreation center was constructed in 1970, the swimming pool was constructed in 1984, and the bandshell was constructed in 1999. Phase 1 updates to the park were completed in 2024 including the new playground, new walking paths, and re -surfaced tennis courts. In November 2024, voters approved a $46.2 million bond referendum to fund Phase 2 of the park renovation, with 64.5% voting in favor. PROPOSAL The petitioner, Studio 222 Architects LLC, on behalf of the property owner, Mt Prospect Park District, is proposing to demolish the existing recreation center and swimming pool, and to construct a new recreation center and swimming pool, including a splash pad, water slides, bath house, and pool equipment building. The petitioner is proposing new outdoor recreational amenities including a skate plaza, basketball court, six pickleball courts, outdoor game area, and seasonal ice rink. Site Plan: The northwest side of the park contains most of the site improvements, while the southwest and east side of the park are predominantly open green space. The park amenities are connected to each other via asphalt walking paths that link to neighborhood sidewalks and the parking lot. The petitioner notes that one of the goals of the site design is to provide direct access from the parking lot to the band shell and other outdoor amenities without having to circulate around the entire building, as with the current facility. The two existing vehicular access points into the subject property, on Maple and Lincoln Street, will remain. The west side of the parking lot encroaches into the public right of way and will require a license agreement between the Mt Prospect Park District and the Village. The overall lot coverage of the subject property will increase to 33%, which is below the maximum allowable lot coverage of 75%. The proposed recreation center is set back 10.2' from Lincoln Street, whereas the underlying zoning district (C-R) requires a minimum setback of 30' for the exterior side yard. The petitioner is requesting a variation from the exterior side yard setback requirements. Staff agrees that the parcel shape and position of existing amenities pose a unique challenge when siting the recreation center, and concurs that the setback requirement would pose a hardship for the park district to create a practical site plan. Staff notes that the existing facility already has a non -conforming setback (17.85') and does not believe that reducing the setback to 10' will alter the essential character of the neighborhood. Staff supports the variation request and finds that it is consistent with the overall goals of the PUD. Recreation Center: The new recreation center will be 42' tall and set back 10.17' from Lincoln Street. The two-story building will be 55,700 square feet and contain a gymnasium, walking track, dance studio, multi -generational room, multi -purpose rooms, art studio, and preschool room. The main entrywill be located on the west elevation, and will feature a metal canopy. The fagade will be constructed of precast concrete panels with various finishes, including Norman -sized cast brick. Design elements will include cast stone coping, woodgrain-finish metal panels, and a prefinished aluminum curtain wall system. The refuse enclosure and loading dock will be located on the northeast elevation and will be screened with a six-foot tall solid panel sliding gate. \\Vfs\vfcdh$\PLAN\Planning & Zoning COMM\P&Z 2D25\Staff Rep orts\PZ-14-25 411 S Maple St (CU-Final PUD and Final Plat of Subdivision).docx 2 Swimming Pool: The swimming pool area consists of a bathhouse (5,352 SF), pool equipment building (1,304 SF), leisure pool with water slides (11,878 SF), splash pad (2,960 SF), and pool deck (22,480 SF). The maximum height of the water slide structure will be 31', measured at the top of the platform canopy. The bathhouse and the pool equipment building facades will be consistent with the materials featured on the recreation building, and will measure 19.66' and 16.33' in height, respectively. Other Amenities: Six pickle ball courts will be installed to the east of the existing tennis courts, and will feature fencing and wind screens similar to the tennis courts. The skate park and basketball court will be located east of the playground. The petitioner noted in their application that the skate park and basketball court locations were chosen because of existing site grading and to maintain open space in the center of the park for programming and concert seating close to the bandshell. The seasonal ice rink will be located south of the recreation center and will be a "flood -type" sheet of ice with a liner and 2x trim board edging. Hours of Operation: The document titled "Lions Memorial Park Land Use Table" dated July 17, 2025 (see Exhibit B) details the hours of operation and outdoor lighting for the current and proposed amenities. The time range represents the earliest and latest times proposed for each amenity, though it is not expected that every amenity will operate every day for the entire operating window. The recreation center is proposed to operate 6AM to 11 PM year-round. The pool is proposed to operate 6AM to 9PM during the summer season, however, the pool will be closed when events take place at the bandshell. The bandshell is proposed to operate between 7AM to 10PM during the summer season. Outdoor sports courts with lighting (baseball fields, tennis courts, pickle ball courts, and ice rink) are proposed to operate between 7AM to 10PM, seasonally. Outdoor amenities without lighting (playground, skate plaza, basketball court, outdoor game area, and pedestrian paths) are proposed to operate from dawn to dusk. Parking: The petitioner provided a parking study to estimate parking demand for the site using various methods. The study noted that the new recreation center will accommodate fewer people than the existing building (523 versus 589) however the maximum occupancy for all outside uses is increasing from 1,640 to 1,990. Overall capacity is increasing by approximately 13%, not considering seasonality and scheduling. The existing uses require approximately 800 parking stalls according to code, yet the subject property currently contains 179 parking stalls on site. Much like how the existing facility is short on parking when all uses are contemplated simultaneously, the new facility will also be short on code -required parking. However, the Mt Prospect Park District does not operate all uses at the same time, and is working with Staff to provide a Special Event Parking Management Plan, is pursuing parking agreements with adjacent and nearby property owners, and has committed to a review of actual parking impacts once the facility opens. Parking Supply The petitioner is proposing to add 21 parking stalls to the existing parking lot, increasing the total from 179 to 200 parking stalls (approximately 12% increase). The parking study included a parking survey that assessed the parking available on weekdays and weekends in nearby parking lots and parking garages. For example, on a weekday after 4PM, Lions Park Elementary School has an estimated 78 spots available, and Maple Street Parking Deck has an estimated 167 spots available. The Mt Prospect Park District is exploring off-street parking agreements with Dason Community Church (30- 50 spaces) and Busse Automotive (50-75 spaces). The parking study also documented on -street \Wfs\vfcdh$\PLAN\Planning & Zoning COMM\P&Z 2025\Staff Repo rts\PZ-14-25 411 S Maple St (CU-Final PUD and Final Plat of Subdivision). docx parking around the site, estimating 715 on -street parking spots available on a weekday after 4PM. Staff is encouraging that off-street parking options are explored before resorting to on -street parking. The study included parking supply information from three Arlington Park District properties (Recreation, Camelot, and Frontier) which have maximum occupancy capacities ranging from 1,608 to 1,844 people and on -site parking provided ranging from 72 to 93 parking spaces. In comparison, Lions Memorial Park proposed capacity is 1,990 and will have 200 on -site parking spaces, more than double those other area facilities. Parking Demand The zoning code requires a minimum number of off-street parking spaces based square footage and occupancy for each use. The study suggests 1,070 off-street parking spaces are required for the site according to the zoning code.' The calculation is based on the maximum occupancy of each individual use occurring simultaneously, which would not occur in reality. Staff notes that the zoning code allows for reduced off-street parking in B-5 and B-SC Central Commercial zoning districts - generally 50% of the parking required in other districts. While the subject property is zoned C-R Conservation Recreation as it is a park, it is immediately adjacent to the B-5 Central Commercial zoning district and just down the street from the Maple Street Parking Deck, which has 262 parking stalls. 50% of the minimum parking requirement would be 535 parking spaces.' The parking study provided an estimate of parking demand based on the Institute of Transportation Engineers (ITE) data and local data, which suggested that peak demand would be 553 vehicles, 55% Less than the zoning code minimum.' The Mt Prospect Park District provided estimates of actual park activities taking place across the seasons, by time of day, versus maximum activity. Using this method, the park district estimates demand to range from 154 vehicles on the low end, to 612 vehicles during a Thursday concert at the bandshell.4 It shows that on a normal, non -concert day during the summer, parking demand will be roughly 250 vehicles. Staff created Table 1 to estimate the parking deficiency according to the various methods used in the parking study. Based on the 200 stalls to be provided on site, along with the additional parking available in the Maple Street Parking Deck, on -street parking, and potential to secure parking agreements with nearby properties, Staff supports the proposed parking plan. Parking Management Staff is requiring the following mitigation and monitoring measures to address potential parking overflow: 1) A Parking Management Plan detailing parking accommodations for day-to-day activities, demonstrating adequate parking for the facility exists largely onsite; 2) A Special Event Parking Plan detailing additional off -site parking to be provided on nearby properties via off -site parking agreements, usage of the Maple Street Parking Deck, on -street parking, and information on how parking is coordinated for special events; and 3) Monitoring and reporting on the parking management plan, with a report required to be submitted to the Village Manager's Office after one full year of park operation. \Wfs\vfcdh$\PLAN\Planning & Zoning COMM\P&Z 2025\Staff Rep orts\PZ-14-25 411 S Maple St (CU-Final PUD and Final Plat of Subdivision). docx 4 Should the site experience regular overflow with a need for additional parking, the petitioner identified two locations on Lincoln and Maple Streets where angled parking could be added in the public right- of-way adjacent to Lions Memorial Park.

New landscaping is proposed throughout the site to complement the new buildings, enhance the parking lot, and provide limited screening for certain recreational areas, all while prioritizing an open viewshed into the expansive green space. Areas with notable new plantings include robust foundation plantings on the north fagade of the recreation center; shade trees for the parking lot islands; evergreen screening on the west side of the tennis courts and south side of the skate park and basketball court; and water -tolerant species around and within the naturalized storm basin. The petitioner proposes to remove 19 trees to facilitate the improvements and plant 63 new trees comprised of 16 different species. Given the expansive green space provided within the park itself, the intent of the landscape code is met through the overall design, making the full extent of perimeter landscaping unnecessary and allowing for visual and functional value in preserving open, unobstructed greenspace along the park's edges. The petitioner is providing significant landscaping around new amenities and in areas requiring code relief, such as the north face of the new recreation facility. Lighting: The petitioner provided a photometric site plan with new wall mounted lights for the recreation center and pool buildings; illuminated bollards for the walking paths near the recreation center; uplights for the flag pole; and pole -mounted lights for the parking lot. The baseball fields and tennis courts are already equipped with sports lighting, and the petitioner is proposing similar sports Lighting for the pickleball courts, pool area, and seasonal ice rink. A fully compliant photometric plan will be required as part of building permit submittal. Signage: The petitioner intends to replace the freestanding sign at the entrance of the park, containing carved letters and the park district logo on a single -sided plastic surface. The recreation center features an 8' diameter park district logo. The bath house features walls signs identifying the different entryways (aquatics, concessions, guards, first aid). The PUD will approve signage consistent with what is submitted, and any future relief requested for signage shall require an \Wfs\vfcdh$\PLAN\Planning & Zoning COMM\P&Z 2025\Staff Rep orts\PZ-14-25 411 S Maple St (CU-Final PUD and Final Plat of Subdivision). docx application for a minor amendment to the PUD. Stormwater: The subject property has an existing detention area east of the playground and the petitioner is proposing an additional detention area on the east side of the site near William Street. With a new building being constructed on site, the development code requires that stormwater detention be provided for the entire site. However, the petitioner is proposing to provide detention only for the areas being disturbed for this project. The petitioner contends that detaining the stormwater for the entirety of the subject propertywould require an unreasonable amount of space and have a detrimental impact on the park and its abilityto function, especially for events, due to the substantial increase in area required for detention. Therefore, the petitioner is requesting an exception from the development code. The petitioner has submitted an application for a watershed management permit to MWRD with approval from the Public Works Department. With the petitioner providing stormwater detention for the newly proposed amenities, Staff supports this development code exception due to the size and scale of the park. With grass areas that would remain undisturbed, including the ball fields, requiring additional detention to be provided is impractical and detrimental to the project. The intent of this code section is to make outdated, noncompliant commercial property compliant with today's standards, and it is unreasonable to apply such a requirement to a 20-acre park property that is almost 70% open space. Phasing: The petitioner is pursuing project design, permitting, and bidding throughout the summer and fall of 2025. If the proposal is approved by the Village Board, the petitioner will seek Mt Prospect Park District Board approval in October 2025. Demolition of the pool and recreation center is anticipated for October / November 2025, with substantial completion of Phase 2 expected in May 2027. PUBLIC INPUT Mt Prospect Park District (MPPD) has conducted extensive outreach regarding both Phase 1 and Phase 2 of the park renovation. A 30-member Citizen Task Force was created in early 2024 to provide input on the proposed referendum. In the spring and summer of 2024, MPPD collected feedback via a community survey and polling conducted by an independent polling firm. MPPD created a dedicated email address for questions and suggestions, and hosted two community information meetings at the Lions Recreation Center regarding the referendum. After the referendum was passed, MPPD hosted two open houses in January and April 2025 showcasing the preliminary project designs and renderings for public comment. As of this writing, Staff has not received public comment on the proposal. ZONING REQUESTS The proposal requires the following zoning approvals: Final Plat of Subdivision (15.304): The subject property is comprised of two parcels totaling 20.8 acres. The parcels will be consolidated into one lot of record and utility easements will be granted over existing Village storm and combined sewers crossing the site. Final Planned Unit Development (PUD) (14.503.C): A Planned Unit Development (PUD) is required because multiple buildings and accessory structures are proposed for one zoning lot. PUDs provide a tool to accommodate development which is in the public interest, provides a public benefit, and which would not otherwise be permitted by the zoning ordinance. Petitioners can seek relief from many aspects of the zoning code provided the proposal meets the Conditional Use and applicable \Wfs\vfcdh$\PLAN\Planning & Zoning COMM\P&Z 2025\Staff Repo rts\PZ-14-25 411 S Maple St (CU-Final PUD and Final Plat of Subdivision). docx PUD standards. Variation from Exterior Yard Setback (14.504.C.5.a): PUDs allow flexibility with bulk regulations, however, the standards for PUDs with other exceptions require that the setbacks are no less than the required setbacks in the abutting zoning district or the zoning district underlying the subject site, whichever is greater. The proposed recreation center is set back 10.2' from Lincoln Street, whereas the underlying zoning district (C-R) requires a minimum setback of 30' for the exterior side yard. The petitioner is requesting a variation from the exterior side yard setback requirements. Development Code Exception (15.401.13 and 15.402.13): As noted above, the development code requires that the entire site be brought into compliance with current stormwater management standards when a new building is constructed. The petitioner is requesting a development code exception to provide stormwater detention only for the areas to be disturbed as part of this project. ADDITIONAL CONSIDERATIONS When a unit of local government, such as a school district, park district, or county, comes to the Village with a zoning request, the Village's Planning & Zoning Commission and Board of Trustees apply the same standards from the zoning ordinance to the zoning application as it would with a private property owner. However, in addition to the standards in the zoning ordinance, the Planning & Zoning Commission and Board of Trustees need to consider whether any condition of approval or whether a denial of the application would thwart or frustrate the unit of local government's statutory duties. Stated positively, the Village should consider whether the requested relief furthers the statutory mission of the unit of local government and, if it does, give the requested relief some deference. In light of this, for Mt Prospect Park District's application before the Planning & Zoning Commission, in addition to all the typical zoning standards that would be applied, the Planning & Zoning Commission should consider: 1. How does the application relate to the Park District's mission? 2. What are the Park District's statutory duties related to the application? 3. What sections of the Park District Code would be affected if the application is granted or denied? 4. How does the application relate to the Park District's statutory duties? 5. Would the Park District's statutory duties be frustrated if the Village denied the application? If yes, how so? 6. If the application were granted, would the Park District be able to more fully meet its statutory duties? If yes, how so? When considering these questions, the Planning and Zoning Commission should rely on 70 ILCS 1205/8, the most important of which is section 10 (70 ILCS 1205/8-10), which outlines the statutory powers and duties of park districts. A copy of the referenced section of the Park District Code, 70 ILCS 1205/8-10, is attached hereto. The petitioner asserts that granting the requested relief serves the public interest by improving mental and physical health, contributing to positive environmental outcomes, and increasing property values. The petitioner states that they carefully considered the site design to balance the recreational needs of the community with the impact on the surrounding neighborhood. The petitioner suggests that adhering to the strict letter of the code would have a severe, detrimental impact on the character \Wfs\vfcdh$\PLAN\Planning & Zoning COMM\P&Z 2025\Staff Rep orts\PZ-14-25 411 S Maple St (CU-Final PUD and Final Plat of Subdivision). docx 7 of the site and neighborhood, and would potentially render the project financially infeasible. STANDARDS AND FINDINGS The Planning and Zoning Commission shall review the standards and findings of fact outlined in Exhibit A and 1) accept them without changes, 2) accept them with changes, or 3) reject the findings. The Planning and Zoning Commission shall use the findings of fact to guide their recommendation to the Village Board. Staff finds that the proposal meets the applicable standards contained in the Mount Prospect Zoning Ordinance.

That the establishment, maintenance, or operation of the conditional use will not be detrimental to, or endanger the public health, safety, morals, comfort, or general welfare; 2. That the conditional use will not be injurious to the uses and enjoyment of other property in the immediate vicinityfor the purposes already permitted, nor substantially diminish and impair property values within the neighborhood in which it is to be located; 3. That the establishment of the conditional use will not impede the normal and orderly development and improvement of the surrounding property for uses permitted in the district; 4. That adequate public utilities, access roads, drainage and/or necessary facilities have been or will be provided; 5. That adequate measures have been or will be taken to provide ingress and egress so designed as to minimize traffic congestion in the public streets; 6. That the proposed conditional use is not contrary to the objectives of the current comprehensive plan for the village; and 7. That the conditional use shall, in all other respects, conform to the applicable regulations of the district in which it is located, except as such regulations may, in each instance, be modified pursuant to the recommendations of the planning and zoning commission. Petitioner's Findings: The petitioner states that the park enhances public health through the provision of recreational opportunities and improved air and water quality. The petitioner contends that many of the uses already exist at the park and historicallythe amenities have been well received by the community and neighbors. The petitioner asserts that parks and recreation facilities have a positive impact on surrounding home values. The petitioner notes that the existing and proposed uses are compatible with the residential and institutional uses surrounding the subject property. The petitioner reports that plans will be submitted to the MWRD to ensure all utilities and drainage requirements are met. The petitioner does not expect changes to traffic patterns and provided a parking study as part of the PUD submission. Per the petitioner, the proposal aligns with many of the goals of the Village Comprehensive Plan. The petitioner concludes that they will follow regulations and review all recommendations brought forward by the Planning and Zoning Commission. Staff's Findings: Staff finds that the proposal will update aging public facilities and bring new recreation amenities to an existing community park, thereby supporting public health and general welfare of the community. The petitioner has considered the impact on the neighborhood and solicited community input on the project over the course of two years. Staff has recommended conditions of approval to address potential adverse impacts, such as landscape screening, parking management plans, and guidelines for hours of operation. Based on the information submitted, the surrounding uses, and the proposed development's compliance with the Village's zoning ordinance and long-range planning documents, Staff recommends approval of the conditional use request. \Wfs\vfcdh$\PLAN\Planning & Zoning COMM\P&Z 2025\Staff Reports\PZ-14-25 411 S Maple St (CU-Final PUD and Final Plat of Subdivision).docx 11 GENERAL STANDARDS FOR PLANNED UNIT DEVELOPMENTS Section 14.504.A of the Village of Mount Prospect Zoning Ordinance provides that a Planned Development shall conform to the following requirements: 1. Except as modified by and approved in the final Planned Unit Development plan, the proposed development complies with the regulations of the district or districts in which it is to be located. 2. The principal use in the proposed Planned Unit Development is consistent with the recommendations of the Comprehensive Plan of the Village for the area containing the subject site. 3. The proposed Planned Unit Development is in the public interest and is consistent with the purposes of this zoning ordinance. 4. The streets have been designed to avoid: a. Inconvenient or unsafe access to the Planned Unit Development; b. Traffic congestion in the streets which adjoin the Planned Unit Development; c. An excessive burden on public parks, recreation areas, schools, and other public facilities which serve or are proposed to serve the Planned Unit Development. Petitioner's Findings: The petitioner responded that they carefully considered the site design to balance the needs of the community with the impact on the surrounding neighborhood. The petitioner considers the recreation center setback of approximately 10' from Lincoln Street to be appropriate given the site constraints and the desire to provide direct access from the parking lot to the band shell and other outdoor amenities without having to circulate around the entire building, as with the current facility. The petitioner contends that the C-R district maximum building height of 30' is outdated and that the 42' building height is necessary to accommodate tall ceilings comparable to other modern recreational facilities. The petitioner notes that the interior layout of the gym resulted in an uninterrupted wall span over 200 feet long along Lincoln Street, however the petitioner included 12-foot wide curtainwall windows and substantial foundation landscaping to break up the visual expanse of the fagade. The petitioner asserts that the principle use of the PUD is consistent with many goals of the Village Comprehensive Plan, and suggests that green spaces and community recreation centers improve mental and physical health, contribute to positive environmental outcomes, and increase property values. The petitioner is proposing a sidewalk extension to enhance connection to the neighborhood and asserts that the off-street and on -street parking supplywill meet projected parking demand. Staff's Findings: The PUD provides flexibility for developments to deviate from the strict letter of the code. The proposal deviates in several areas, including bulk requirements (setback, height), stormwater detention, perimeter landscaping, off-street parking requirements, and use exceptions. However, Staff finds that all deviations are in the public interest and consistent with the purpose of the zoning ordinance and the Comprehensive Plan. Staff is requiring a parking management plan, special event parking plan, off -site parking agreements, and monitoring and reporting on the parking supply and demand to minimize traffic and parking congestion in the neighborhood to the greatest extent possible. STANDARDS FOR PLANNED UNIT DEVELOPMENTS WITH USE EXCEPTIONS Section 14.504.13 of the Village of Mount Prospect Zoning Ordinance states that the approving ordinance may provide for uses in the planned development not allowed in the underlying district, provided the following conditions are met: 1. Proposed use exceptions enhance the quality of the planned unit development and are compatible with the primary uses. \Wfs\vfcdh$\PLAN\Planning & Zoning COMM\P&Z 2025\Staff Rep orts\PZ-14-25 411 S Maple St (CU-Final PUD and Final Plat of Subdivision). docx 12 2. Proposed use exceptions are not of a nature, nor are located, so as to create a detrimental influence in the surrounding properties. 3. Proposed use exceptions shall not represent more than forty percent (40%) of the total floor area. However, in a residential planned unit development area no more than ten percent (10%) of the site area or the total floor area shall be devoted to commercial use. No industrial use shall be permitted within a residential planned unit development. Petitioner's Findings: The petitioner asserts that the proposed use exceptions enhance the quality of the planned unit development and are compatible with the primary uses. The petitioner explains that the existing bandshell and lighted baseball fields at Lions Park have been integral to bringing the community together for summer activities and events for many years. The bandshell is the only outdoor music venue in the Village. Similarly, the proposed water slides will be the only slides of their kind in the Village. The petitioner maintains that the preschool/early childhood classroom is compatible with the parks uses and will be similar to the classroom that currently exists within the Central Community Center. The petitioner notes that the new recreation center will replace the existing facility at nearly the same location on the site. The petitioner states that the proposed use exceptions comprise approximately 27.6% of the total site area. Staff's Findings: Staff finds that all proposed use exceptions, including accessory structures greater than 30 feet in height, daycare center (preschool), lighted ball fields, and recreational complexes, are compatible with the primary use, a community recreational complex. Staff finds that the proposed use exceptions are situated on the site and screened in such a way as to dissipate negative impacts on surrounding properties. STANDARDS FOR PLANNED UNIT DEVELOPMENTS WITH OTHER EXCEPTIONS Section 14.504.0 of the Village of Mount Prospect Zoning Ordinance provides that a Planned Development which does not comply with the requirements of the underlying zoning district's regulations governing lot area, lot width, bulk regulations, parking and sign regulations, or which require modification of the subdivision design standards shall conform to the following requirements: 1. Any reduction in the requirements of this chapter is in the public interest. 2. The proposed exceptions would not adversely impact the value or use of any other property. 3. Such exceptions are solely for the purpose of promoting better development which will be beneficial to the residents or occupants of the planned unit development as well as those of the surrounding properties. 4. In residential planned unit developments the maximum number of dwelling units allowed per acre shall not exceed forty eight (48) units per acre for developments incorporating senior housing or assisted living facilities. 5. All buildings are to be located within the planned unit development in such a way as to dissipate any adverse impact on adjoining buildings and shall not invade the privacy of the occupants of such buildings and shall conform to the following: a. The front, side or rear yard setbacks on the perimeter of the development shall not be less than that required in the abutting zoning district(s) or the zoning district underlying the subject site, whichever is greater. b. All transitional yards and transitional landscape yards of the underlying zoning district are complied with. c. If required transitional yards and transitional landscape yards are not adequate to protect the privacy and enjoyment of property adjacent to the development, the Planning and \Wfs\vfcdh$\PLAN\Planning & Zoning COMM\P&Z 2025\Staff Rep orts\PZ-14-25 411 S Maple St (CU-Final PUD and Final Plat of Subdivision). docx 13 Zoning Commission shall recommend either or both of the following requirements: i. All structures located on the perimeter of the planned unit development must be set back by a distance sufficient to protect the privacy and amenity of adjacent existing uses; ii. All structures located along the entire perimeter of the planned unit development must be permanently screened with sight proof screening in a manner which is sufficient to protect the privacy and amenity of adjacent existing uses. d. The area of open space provided in a planned unit development shall beat least that required in the underlying zoning district. Petitioner's Findings: The petitioner responded that the deviations are necessary for optimal park design and functionality for the neighborhood and overall community. The petitioner asserts that parks and recreation facilities have a positive impact on surrounding home values. The petitioner explains that the intent for the site is to maintain a balance of open green space, outdoor recreation areas, and indoor facility space. The petitioner considers the recreation center setback of approximately 10' from Lincoln Street to be appropriate given the site constraints and the desire to provide direct access from the parking lot to the band shell and other outdoor amenities without having to circulate around the entire building, as with the current facility. Staff's Findings: Staff finds that all deviations are in the public interest and will not have an adverse impact on the value or use of surrounding property. The petitioner has considered the impact on the neighborhood and solicited community input on the project over the course of two years. Staff has recommended conditions of approval to address potential adverse impacts, such as landscape screening, parking management plans, and guidelines for hours of operation. The petitioner is seeking a variation from the setback requirement under 14.504.C.5a, because the underlying zoning district (C-R) exterior yard setback requirement is 30' on Lincoln Street, but the proposed setback for the recreation center is approximately 10'. Staff supports the exceptions and finds that they are consistent with the overall goals of the PUD. VARIATION STANDARDS Section 14.203.C.9 of the Village of Mount Prospect Zoning Ordinance provides that Variation shall conform to the following requirements: 1. Because of the particular physical surroundings, shape, or topographical conditions of the specific property involved, a specific hardship to the owner would result, as distinguished from a mere inconvenience if the strict letter of the regulations was to be applied; 2. The conditions upon which an application for a variation are based are unique to the property for which the variation is sought and are not generally applicable to other property within the same zoning classification; 3. The purpose of the variation is not based primarily upon a desire to increase financial gain; 4. The alleged difficulty or hardship is caused by this chapter and has not been created by any person presently having an interest in the property; 5. The granting of the variation will not be detrimental to the public welfare or injurious to other property or improvements in the neighborhood in which the property is located; 6. The granting of the variation will not alter the essential character of the neighborhood; and 7. The proposed variation will not impair an adequate supply of light and air to adjacent property or substantially increase the congestion of the public streets, or increase the danger of fire, or impair natural drainage or create drainage problems on adjacent properties, or endanger the \Wfs\vfcdh$\PLAN\Planning & Zoning COMM\P&Z 2025\Staff Rep orts\PZ-14-25 411 S Maple St (CU-Final PUD and Final Plat of Subdivision). docx 14 public safety, or substantially diminish or impair property values within the neighborhood. Petitioner's Findings: The petitioner considers the recreation center setback of approximately 10' from Lincoln Street to be appropriate given the site constraints and the desire to provide direct access from the parking lot to the band shell and other outdoor amenities without having to circulate around the entire building, as with the current facility. The petitioner argues that the proposed recreation center is one of a kind and that the 30' setback requirement is unrealistic for a modern facility of this size. The petitioner explains that the goal of the new facility and site related improvements is to integrate with the existing uses on site and provide direct access from the parking lot to the entire park via a generous and welcoming passageway between the pool building and recreation center, a.k.a. "the gateway to the park." The petitioner notes that the hardship is not caused by any person presently having an interest in the property. The petitioner explains that the park and recreation center can help enhance public health and reduce stress by promoting physical activity including walking, visual and performing arts, sports, and many other programming opportunities. In addition, the welcoming passageway between the pool building and recreation center will also serve as fire truck access around the new facility. The petitioner notes that historically, these amenities have all been well received by the community and surrounding neighbors and have not been a nuisance. The petitioner points out that the existing recreation center does not comply with the 30' setback requirement; therefore, the proposed setback for the new facility will not alter the essential character of the neighborhood. The petitioner concludes that the exception will not reduce the supply of light and air, increase congestion, increase fire risk, create drainage problems, endanger public safety, or diminish property values. Staff's Findings: Staff agrees that the parcel shape and position of existing amenities pose a unique challenge when siting the recreation center, and concurs that the setback requirement would pose a hardship for the park district to create a practical site plan. Staff does not see financial gain as a driving force behind the variation request. Staff is requiring design elements and foundation landscaping to provide visual interest on the north elevation of the recreation center. Staff notes that the existing facility already has a non -conforming setback (17.85') and does not believe that reducing the setback to 10' will alter the essential character of the neighborhood. Staff supports the variation request and finds that it is consistent with the overall goals of the PUD. STANDARDS FOR DEVELOPMENT CODE EXCEPTIONS Section 15.109 provides that exceptions may be granted from the Village of Mount Prospect Development Code upon finding that severe hardship, caused by conditions uniquely attributable to the land under consideration, would be imposed upon an applicant by compliance with these regulations and upon a finding that there are alternate feasible means of fulfilling the purpose and spirit of the regulations to protect the public health, safety and welfare, if findings of fact based on evidence are made in each specific case that affirm the following standards: 1. Because of the particular physical surroundings, shape, or topographical conditions of the specific property involved, a specific hardship to the owner would result, as distinguished from a mere inconvenience if the strict letter of the regulations was to be applied; 2. The conditions upon which an application for an exception are based are unique to the property for which the exception is sought and are not generally applicable to other property within the same zoning classification; 3. The purpose of the exception is not based primarily upon a desire to increase financial gain; 4. The alleged difficulty or hardship is caused by this chapter and has not been created by any person presently having an interest in the property; \Wfs\vfcdh$\PLAN\Planning & Zoning COMM\P&Z 2025\Staff Rep orts\PZ-14-25 411 S Maple St (CU-Final PUD and Final Plat of Subdivision). docx 15 5. The granting of the exception will not be detrimental to the public welfare or injurious to other property or improvements in the neighborhood in which the property is located; 6. The granting of the exception will not alter the essential character of the neighborhood; and 7. The proposed exception will not impair an adequate supply of light and air to adjacent property or substantially increase the congestion of the public streets, or increase the danger of fire, or impair natural drainage or create drainage problems on adjacent properties, or endanger the public safety, or substantially diminish or impair propertyvalues within the neighborhood. Petitioner's Findings: The petitioner states that the property is unique in nature in that it is primarily undeveloped green space with minimal drainage slopes and interspersed drainage patterns and infrastructure. The petitioner asserts that it is not practical to route the entirety of the property to stormwater management facilities, especially when considering that the site is primarily green space, therefore resulting in much less runoff than a traditional site of similar size. The petitioner explains that the purpose of the exception is to account for the stormwater benefits provided by the site in its current state as well as continue to maximize use of and preserve recreational space and opportunities for park patrons. The petitioner contends that the hardship is due to the unique conditions of the site as well as lack of provisions in Village code to account for the large portions of the site that will remain undisturbed. The petitioner argues that the granting of the exception will not be detrimental to public welfare or adjacent property owners, as the improvements include significant stormwater management improvements for large portions of the site, which will have significant local watershed benefits. The petitioner suggests that adhering to the requirements would have a severe, detrimental impact on the character of the site and neighborhood, as significant portions of the valuable open space would need to be converted to stormwater management areas in order to fully comply with Village requirements. The petitioner concludes that the exception will not reduce the supply of light and air, increase congestion, increase fire risk, or create drainage problems. Staff's Findings: Sections 15.4013 and 15.402.B of the Village Code require that the entire site be brought into compliance with current stormwater management standards when a new building is constructed. With the petitioner providing stormwater detention for the newly proposed amenities, Staff supports this development code exception due to the size and scale of the park. With grass areas that would remain undisturbed, including the ball fields, requiring additional detention to be provided is impractical and detrimental to the project. The intent of this code section is to make outdated, noncompliant commercial property compliant with today's standards, and it is unreasonable to apply such a requirement to a 20-acre park property that is almost 70% open space. Staff concurs that this code requirement would place a severe hardship on the proposed development. Staff further concurs that the development as proposed would provide significant stormwater management benefits to the watershed where currently none exist. Staff finds that the development code exception standards have been met and supports the request for an exception. \Wfs\vfcdh$\PLAN\Planning & Zoning COMM\P&Z 2025\Staff Reports\PZ-14-25 411 S Maple St (CU-Final PUD and Final Plat of Subdivision).docx 16 Exhibit B Lions Memorial Park Land Use Table Existing and Proposed Site Amenities 7.17.2025 Use Current;l-laurs Proposed; Hours 'Outdoor, Lighting Year Round; 7am-9pm Recreation Center Monday through Friday and Year Round; 6am-11 pm No 7am-4pm Saturdays and Monday through Sunday Sundays May -August; 1 pm-6:30pm Mondays, Wednesday, Friday, Seasonal; May -September; Community Pool 11:30am-5pm Thursdays, 11: 6am-9pm, Monday through No 30am-5pm Saturdays and Sunday Sundays Seasonal; May -September; Outdoor Splash Pad N/A 6am-9pm, Monday through No Sunda Playground yg Year Round; dawn to dusk, Year Round; dawn to dusk, No Monday through Sunday Monday through Sunda Seasonal; 5pm-10pm Seasonal; 7am-10pm for Park Bandshell Mondays and Thursdays.

Describe HOW your proposal will meet each standard. Copy this list onto letterhead and then type answers for each point. 15.109: EXCEPTIONS: Upon findingthat severe hardship, caused by conditions uniquely attributable to the land under consideration, would be imposed upon an applicant by compliance with these regulations and upon a finding that there are alternate feasible means of fulfilling the purpose and spirit of the regulations to protect the public health, safety and welfare, the planning and zoning commission may recommend, and the president and board of trustees may grant exceptions from the regulations of this chapter. However, no exception from the regulations of this chapter shall be granted or recommended for approval by the planning and zoning commission unless findings of fact based on evidence are made in each specific case that affirm the following standards: A. Because of the particular physical surroundings, shape, or topographical conditions of the specific property involved, a specific hardship to the owner would result, as distinguished from a mere inconvenience if the strict letter of the regulations was to be applied; Response: The property is unique in nature in that it is primarily undeveloped green space with minimal drainage slopes and interspersed drainage patterns and infrastructure. It is not practical to route the entirety of the property to stormwater management facilities, especially when considering that the site is primarily green space, therefore resulting in much less runoff than a traditional site of similar size. B. The conditions upon which an application for an exception are based are unique to the property for which the exception is sought and are not generally applicable to other property within the same zoning classification; Response: The property characteristics are unique in that it is primarily undeveloped pervious area that generates minimal stormwater runoff compared to a typical site, while also being impractical to collect and route the entirety of the property to stormwater management system(s). C. The purpose of the exception is not based primarily upon a desire to increase financial gain; Response: The purpose of the exception is to account for the stormwater benefits provided by the site in its current state as well as continue to maximize use of and preserve recreational space and opportunities for park patrons. It is not based upon a desire to increase financial gain. D. The alleged difficulty or hardship is caused by this chapter and has not been created by any person presently having an interest in the property; Response: The difficulty is due to the aforementioned unique conditions of the site as well as lack of provisions in Village code to account for the large portions of the site that will remain undisturbed and unchanged by the improvements. The proposed improvements are in accordance with the Metropolitan Water Reclamation District's (MWRD) Watershed Management Ordinance (WMO). E. The granting of the exception will not be detrimental to the public welfare or injurious to other property or improvements in the neighborhood in which the property is located; Response: The granting of the exception will not be detrimental to public welfare or adjacent property owners, as the improvements include significant stormwater management improvements for large portions of the site, which will have significant local watershed benefits. The intent of the exception is to align Village requirements with MWRD requirements for stormwater management provisions. F. The granting of the exception will not alter the essential character of the neighborhood; and Mount Prospect Chapter 15 Code Exception Standards REQUESTING RELIEF FROM STORMWATER DETENTION REQUIREMENTS Response: The granting of the exception will minimize the impact to the character of the neighborhood. Conversely, adhering to the requirements would have a severe, detrimental impact on the character of the site and neighborhood, as significant portions of the valuable open space would need to be converted to stormwater management areas in order to fully comply with Village requirements. G. The proposed exception will not impair an adequate supply of light and air to adjacent property or substantially increase the congestion of the public streets, or increase the danger of fire, or impair natural drainage or create drainage problems on adjacent properties, or endanger the public safety, or substantially diminish or impair property values within the neighborhood. Response: The proposed exception will have no impact on supply of light and air, will not increase congestion on streets, and will not create danger of fire. The improvements seek to improve natural drainage and provide sizable stormwater management improvements, offering significant stormwater benefits to local sewers. May 7th, 2025 Village of Mount Prospect Community Development Department 50 S. Emerson Street Mount Prospect, Illinois 60056 Phone: (847) 818-5328 Conditional Use - No conditional use shall be recommended for approval by the planning and zoning commission unless it finds: 1. That the establishment, maintenance, or operation of the conditional use will not be detrimental to, or endanger the public health, safety, morals, comfort, or general welfare; • The Mt. Prospect Park District will conduct and perform routine maintenance and inspections to the facilities and grounds including but not limited snow removal, mowing, landscaping, pathway and game court inspection and repair, and other site related maintenance. • The park and recreation center can help enhance public health and reduce stress by promoting physical activity including walking, visual and performing arts, sports, and many other programming opportunities. The open park space improves air and water quality and adds protection from flooding, by absorbing rainwater and providing natural drainage. 2. That the conditional use will not be injurious to the uses and enjoyment of other property in the immediate vicinity for the purposes already permitted, nor substantially diminish and impair property values within the neighborhood in which it is to be located; • The Mt. Prospect Park District will enhance recreational opportunities within the limits of the Lions Memorial Park including building a new recreational facility, community pool, and site related improvements. • Facility improvements include: a walking track, basketball courts and spaces for preschool/early childhood, visual/performing arts, senior/active adult and other programs. • Pool improvements include: a zero -depth entry, aquatic spray features, water slides and lap lanes. The Park District is also planning to install a splashpad within the confines of the pool area. • Site related improvements include: improved parking, constructing six pickleball courts, skate plaza, an outdoor game area, and other site improvements. • Existing site amenities will continue to be available during construction. This includes the Veterans Memorial Bandshell, playground, ballfields, and tennis courts. • Studies have proven that park and recreational facility improvements have a positive impact on surrounding home values, increasing the market appeal. Property owners are attracted to available open space and recreational amenities in their neighborhoods. Additional information on this topic is available at: https.11www.ilparks. org/general/custom.asp?page=PropertyValues • Many of the uses already exist at the Lions Memorial Park, including a playground, tennis courts, baseball fields, open space, including a walking path system, and pool/recreation center. Historically, these amenities have all been well received by the community and surrounding neighbors and have not been a nuisance to the community. 3. That the establishment of the conditional use will not impede the normal and orderly development and improvement of the surrounding property for uses permitted in the district; • The Mt. Prospect Park District will enhance and develop the property within its own parcel limits. The Park is existing and the conditional uses requested are compatible with the residential and institutional uses surrounding the property at Lions Memorial Park. 4. That adequate public utilities, access roads, drainage and/or necessary facilities have been or will be provided; • Plans will be submitted to the Village of Mount Prospect, Illinois Department of Public Health, and Metropolitan Water Reclamation District (MWRD) to ensure all necessary utilities, access roads, and stormwater requirements are being met including building codes and regulations. 5. That adequate measures have been or will be taken to provide ingress and egress so designed as to minimize traffic congestion in the public streets; • The Mt. Prospect Park District will ensure that there is a dedicated construction access road identified and maintained throughout construction on the property. A dedicated staging area will also be identified on site. Street cleaning will take place on an as needed basis and continue throughout construction. Additionally, construction fencing and barricades will be placed throughout the site, as an added safety measure to the public. • The Park District has engaged a Construction Management firm (Nicholas & Associates) dedicated to overseeing the development. • The Park District does not expect any change to existing traffic patterns with the proposed improvements. However, we will be providing a parking study as part of the PUD submission. 6. That the proposed conditional use is not contrary to the objectives of the current Comprehensive Plan for the Village; and • The Mt. Prospect Park District will work with Village staff to align goals and objectives identified in the Village's Comprehensive Plan. The Village Board adopted the official Comprehensive Plan of 2017 for the Village of Mount Prospect at the November 7th, 2017 Village Board meeting. • Goal #1 Promote a sustainable mix of uses and densities along major corridors that encourage a healthy lifestyle, and promote the community's amenities as local and regional des na ons. • 1.2.5. Encourage shared parking agreements where possible. • 1.5.1. Encourage the development of outdoor areas that provide opportunities for the community to gather like plazas, sidewalk cafes, and pop-up parklets. Implement on Strategies 1-4, 3-8 • Goal 4 Further inter -governmental relationships with surrounding communities and other regional agencies to better the community. o 4.1.1. Continue to cooperate with neighboring jurisdictions on issues and the interest of mutual interest, and periodically review and update intergovernmental agreements that recognize the comprehensive plans of each community. • Goal 5 Strengthen the unique identity and character of the community. • 5.1.5. Promote the family friendly amenities in the community. • 5.3.1. Continue to evaluate and implement best practices to encourage the maintenance of buildings throughout the community. • 5.6.3. Conduct a study to re-evaluate the locations of street furniture around community amenities and downtown and make a plan to fund and provide trash receptacles, benches, bike racks, etc. where they are needed. • Goal 6 Encourage walkability by providing convenient access to community resources. o 6.1.1. Promote a geographic distribution of service and recreation oriented uses across the Village, and work with local Park Districts to identify and provide facilities in under -served areas. • 6.1.2. Evaluate pedestrian and bicycle access to local schools, parks, and other community amenities and provide necessary improvements to improve access. Implement strategy 2-15. • 6.1.3. Promote the use of joint -use agreements between service providers to maximize the use of existing facilities in the community. • Goal 7 Ensure that all parts of the community are well served by infrastructure, and support their maintenance and enhancement to serve the future needs of the community. o 7.1.4. Continue to monitor and improve the stormwater system to minimize flooding throughout the Village. 7. That the conditional use shall, in all other respects, conform to the applicable regulations of the district in which it is located, except as such regulations may, in each instance, be modified pursuant to the recommendations of the Planning & Zoning Commission. • The Mt. Prospect Park District will conform and follow regulations and review all recommendations brought forward by the Planning & Zoning Commission. August 11th, 2025 Village of Mount Prospect Community Development Department 50 S. Emerson Street Mount Prospect, Illinois 60056 Phone: (847) 818-5328 14.504: STANDARDS FOR PLANNED UNIT DEVELOPMENTS: Except as provided below, no planned unit development shall be approved unless the development meets the standards for conditional uses, and the standards set forth in this section: A. General Standards 1. Except as modified by and approved in the final planned unit development plan, the proposed development complies with the regulations of the district or districts in which it is to be located. • Throughout the development of the site design, we have carefully considered the placement of all buildings and structures on the site while trying to balance their impact on the surrounding neighborhood, and at the same time responding to the communities requested amenities and space programming needs. One of the primary site design goals was to provide direct access from the parking lot to the band shell, playground, skate park, basketball court, and open park space. This avoids the need for patrons having to circulate around the entire building, a major drawback of the current facility. With the desire to maintain a generous and welcoming passageway between the pool building and recreation center, we feel that the proposed building setback along Lincoln Street of approximately 10'-0" at the Northeast corner and increasing to approximately 14'-8" at the Northwest corner is appropriate, considering the site constraints we are working with. • The C-R district maximum building height of 30'-0" is very restrictive for a modern two-story Park District recreation facility. Many of the programming spaces such as the gymnasium with a walking track, dance rooms, and the multi -generational room with a stage, require tall ceilings that are comparable to other modern recreation facilities. This, combined with long unobstructed structural spans, all contribute to a taller building. When laying out the spaces, we made a conscious effort to locate the spaces that allow for a shorter building height, of 36-0" to the top of the parapet, along Lincoln Street. The tall element along Lincoln Street that shows a 42' 0" building height is set back approximately 150 feet from Lincoln Street. Additionally, we are utilizing building parapet walls to screen rooftop mechanical equipment which we feel is a more appropriate and aesthetically pleasing screening solution, rather than providing screen walls around individual roof top mechanical units. • Section 14.301.1(A)(3)(b) Access — Due to the positioning of the existing parking lot, the location of the building, and the interior program, providing a building entrance at the front facing Lincoln Street is not practical. • Section 14.301.1(A)(3)(c) Windows and Doors — Given the interior layout, which includes three basketball courts, the design incorporates windows to cover 28% of the facade facing Lincoln Street. To enhance visual appeal and break up the facade, we have strategically placed curtain wall windows at five locations. These additions provide architectural interest while maintaining the functionality and safety of those using the indoor basketball courts. • Section 14.301.1(A)(3)(d) Rooflines — Because of the modern style of the building design, rather than traditional cornices and dormers, we have integrated parapet walls featuring varying finishes such as precast and brick with cast stone coping, as well as curtainwall incorporating spandrel glass and wood -tone metal panel infills. • Section 14.301.1(A)(3)(e) Materials —The building materials include Norman size face brick and cast stone at the base of the building, architectural precast with three textures/finishes including fluted form liner, acid etched and polished precast. There will also be a curtain wall system with clear vision glass and wood -tone metal panel spandrels. All finishes have been selected to complement each other as well as the adjacent architecture, by incorporating a warm tone color palette. • Section 14.301.1(A)(3)(f) Vertical Massing of Multi -Story Buildings — The vertical massing of the building is divided using brick masonry and curtainwall windows at the base. The second floor uses architectural precast with different textures, as well as curtainwall with clear glass and wood tone metal panel infills. • Three of the four Rec Center sides comply with Section 14.304.1(B)(1). The building facade facing Lincoln Street is 202'-0" long. Due to the nature of the interior program (3 basketball courts) this facade does not easily lend itself to staggers/offsets. To break up the visual expanse of the facade as intended by the code section, we have provided curtainwall windows approximately 12 feet wide and projecting 12" from the face of the precast panels. These curtainwall windows would span the full height of the building at five locations along the length of the facade. These curtain walls use a combination of clear vision glass, spandrel glass to match the vision glass, and wood -tone metal panel infills as well as curtain wall integrated sunshades to add visual interest. Additionally, the architectural precast on the second floor incorporates three distinct textures and finishes: a fluted form liner, an acid -etched surface, and a polished concrete finish. • The trash enclosure was moved back to comply with the 10-foot setback requirement. The trash enclosure will be constructed of face brick masonry, matching building colors, to a height of 6'4". The enclosure will include a 6' high sliding gate to screen the loading dock area. 2. The principal use in the proposed planned unit development is consistent with the recommendations of the Comprehensive Plan of the Village for the area containing the subject site. • The Mt. Prospect Park District will work with Village staff to align goals and objectives identified in the Village's Comprehensive Plan. The Village Board adopted the official Comprehensive Plan of 2017 for the Village of Mount Prospect at the November 7th, 2017 Village Board meeting. • Goal 1 Promote a sustainable mix of uses and densities along major corridors that encourage a healthy lifestyle, and promote the community's amenities as local and regional destinations. • 1.2.5. Encourage shared parking agreements where possible. • 1.5.1. Encourage the development of outdoor areas that provide opportunities for the community to gather like plazas, sidewalk cafes, and pop-up parklets. Implement on Strategies 1-4, 3-8 • Goal 4 Further inter -governmental relationships with surrounding communities and other regional agencies to better the community. o 4.1.1. Continue to cooperate with neighboring jurisdictions on issues and the interest of mutual interest, and periodically review and update intergovernmental agreements that recognize the comprehensive plans of each community. • Goal 5 Strengthen the unique identity and character of the community. • 5.1.5. Promote the family friendly amenities in the community. • 5.3.1. Continue to evaluate and implement best practices to encourage the maintenance of buildings throughout the community. • 5.6.3. Conduct a study to re-evaluate the locations of street furniture around community amenities and downtown and make a plan to fund and provide trash receptacles, benches, bike racks, etc. where they are needed. • Goal 6 Encourage walkability by providing convenient access to community resources. o 6.1.1. Promote a geographic distribution of service and recreation oriented uses across the Village, and work with local Park Districts to identify and provide facilities in under -served areas. • 6.1.2. Evaluate pedestrian and bicycle access to local schools, parks, and other community amenities and provide necessary improvements to improve access. Implement strategy 2-15. • 6.1.3. Promote the use of joint -use agreements between service providers to maximize the use of existing facilities in the community. • Goal 7 Ensure that all parts of the community are well served by infrastructure, and support their maintenance and enhancement to serve the future needs of the community. o 7.1.4. Continue to monitor and improve the stormwater system to minimize flooding throughout the Village. 3. The proposed planned unit development is in the public interest and is consistent with the purposes of this zoning ordinance. • Green spaces and community recreation centers are increasingly valuable and provide cost-effective public health resources that improve mental and physical health and positive environmental outcomes for communities. These areas offer a gathering place to share activities, contribute to economic growth and a platform to bolster social connections through both group activities and informal encounters. Additionally, parks have proven to increase property values and reduce crime in communities. 4. The streets have been designed to avoid: a. Inconvenient or unsafe access to the planned unit development; b. Traffic congestion in the streets which adjoin the planned unit development; c. An excessive burden on public parks, recreation areas, schools, and other public facilities which serve or are proposed to serve the planned unit development. • With new multifamily development in the area, the proposed improvements are designed and intended to better serve the community due to increased growth. A parking study has been conducted and will be provided with this letter. • Based on the maximum possible occupancy of the building and grounds, national parking data for recreation centers and parks indicates the peak demand would be 553 vehicles. The combined on -site, off -site, and on -street parking supply provides over 1,087 parking spaces which is twice the peak surveyed demand with the addition. • Our intent is to extend the sidewalk along the East side of Maple from Lincoln to the existing asphalt path on Park District property- the proposed improvement adds +/- 100LF of 5' sidewalk path. Patrons walking from the North or West could then walk down Maple, to the path, and to the front entrance of the park and recreation center. The added sidewalk along Maple would provide a good neighborhood connection. C. Standards For Planned Unit Developments With Other Exceptions The Village Board may approve planned unit developments which do not comply with the requirements of the underlying zoning district's regulations governing lot area, lot width, bulk regulations, parking and sign regulations, or which require modification of the subdivision design standards when such approval is necessary to achieve the objectives of the proposed planned unit development, but only when the Board finds such exceptions are consistent with the following standards: 1. Any reduction in the requirements of this chapter is in the public interest. The deviations are necessary for the purpose of making the best design and functionality decisions for the neighborhood and the overall positive impact for the community. With the desire to maintain a generous and welcoming passageway between the pool building and recreation center, we feel that the proposed building setback along Lincoln Street of approximately 10'-0" at the N Northeast corner and increasing to approximately 14'-8" at the Northwest corner is appropriate considering the site constrains we are working with. The trash enclosure is moved back to comply with the 10-foot setback requirement. The programming spaces such as the gymnasium with a walking track, dance rooms, and the multi -generational room with a stage, require tall ceilings that are comparable to other modern recreation facilities. Additionally, we are utilizing building parapet walls to screen rooftop mechanical equipment which we feel is a more appropriate and aesthetically pleasing screening solution, rather than providing screen walls around individual roof top mechanical units. The intent for the site as a whole is to maintain a balance of open greenspace, outdoor recreation areas, and indoor facility space, to stay below the maximum lot coverage. 2. The proposed exceptions would not adversely impact the value or use of any other property. The deviations are necessary for the purpose of making the best design and functionality decisions for the neighborhood and the overall positive impact for the community. With the desire to maintain a generous and welcoming passageway between the pool building and recreation center, we feel that the proposed building setback along Lincoln Street of approximately 10'-0" at the Northeast corner and increasing to approximately 14'-8" at the Northwest corner is appropriate considering the site constrains we are working with. The trash enclosure is moved back to comply with the 10-foot setback requirement. The programming spaces such as the gymnasium with a walking track, dance rooms, and the multi -generational room with a stage, require tall ceilings that are comparable to other modern recreation facilities. Additionally, we are utilizing building parapet walls to screen rooftop mechanical equipment which we feel is a more appropriate and aesthetically pleasing screening solution, rather than providing screen walls around individual roof top mechanical units. The intent for the site as a whole is to maintain a balance of open greenspace, outdoor recreation areas, and indoor facility space, to stay below the maximum lot coverage. 3. Such exceptions are solely for the purpose of promoting better development which will be beneficial to the residents or occupants of the planned unit development as well as those of the surrounding properties. Studies have proven that park and recreational facility improvements have a positive impact on surrounding home values, increasing the market appeal. Property owners are attracted to available open space and recreational amenities in their neighborhoods. Additional information on this topic is available at: https.11www.iiparks.org general/custom.asp?pa_-qe=PropertyValues 4. In residential planned unit developments the maximum number of dwelling units allowed per acre shall not exceed forty eight (48) units per acre for developments incorporating senior housing or assisted living facilities. Not applicable to this project. 5. All buildings are to be located within the planned unit development in such a way as to dissipate any adverse impact on adjoining buildings and shall not invade the privacy of the occupants of such buildings and shall conform to the following: a. The front, side or rear yard setbacks on the perimeter of the development shall not be less than that required in the abutting zoning district(s) or the zoning district underlying the subject site, whichever is greater. b. All transitional yards and transitional landscape yards of the underlying zoning district are complied with. c. If required transitional yards and transitional landscape yards are not adequate to protect the privacy and enjoyment of property adjacent to the development, the Planning and Zoning Commission shall recommend either or both of the following requirements: (1) All structures located on the perimeter of the planned unit development must be set back by a distance sufficient to protect the privacy and amenity of adjacent existing uses; (2) All structures located along the entire perimeter of the planned unit development must be permanently screened with sightproof screening in a manner which is sufficient to protect the privacy and amenity of adjacent existing uses. The Mt. Prospect Park District will enhance recreational opportunities within the limits of the Lions Memorial Park including building a new recreational facility, community pool, and site related improvements to further increase and improve many of the park amenities. Including a playground, tennis courts, baseball fields, open space, and pedestrian path system. Historically, these amenities have all been well received by the community and surrounding neighbors and have not been a nuisance to the community. The proposed building setbacks allow for adequate circulation around the building and into the park. Something that the current facility does not have. The building limits on the North lot line along Lincoln St. will include a mixture of ornamental trees, shrubs, and other perennials. The exterior grades will slope to nearly meet the finished floor elevations. There will be parapet walls on the roof to provide screening for any mechanical equipment. Evergreens are being proposed for additional landscape screening near the Southern limits of the skate plaza and basketball court. New landscaping along with windscreening is being proposed on the West side of the tennis courts along South Maple St. The proposed improvements will have misters and drip irrigation to enhance the growth and quality of the plantings. d. The area of open space provided in a planned unit development shall be at least that required in the underlying zoning district. The proposed recreation center, bathhouse, and pool equipment building will have a total site footprint of approximately 42,272 SF. The existing impervious areas equate to approximately 280,000 SF, with proposed improvements adding an additional 23,000 SF, for a combined total of 303,000 SF of coverage. The total available square footage of the site is 899,147 SF. This equates to approximately 33% of lot coverage, which is below the maximum allowable of 75%.

Standards For Planned Unit Developments With Use Exceptions The ordinance approving the final development plan for the planned unit development may provide for uses in the planned development not allowed in the underlying district, provided the following conditions are met: 1. Proposed use exceptions enhance the qualify of the planned unit development and are compatible with the primary uses. Proposed Uses: The Use Exceptions have been highlighted yellow. Land Use C-R Accessory structures P Accessory structures greater than 30 feet in height (wafer slides, bandshell) C Daycare center (preschool) Lighted ball fields (baseball fields) C Parks and playgrounds P Recreational complexes C Tennis courts, swimming pools, volleyball courts, and similar recreational facilities P Unlighted ball fields P The proposed Use Exceptions indicated above enhance the quality of the planned unit development and are compatible with the primary uses. Throughout the years, the Park District has continued to make improvements to the site and is committed to continuing to provide a wide variety of programming, special events, and recreational opportunities at Lions Memorial Park - both indoors and outdoors, for years to come. The existing bandshell and lighted baseball fields at Lions Park have been integral to bringing the community together for summer activities and events for many years. The bandshell is the only outdoor music venue in the Village. Similarly, the proposed water slides will be the only slides of their kind in the Village. While Meadows Pool has an 8'-0" drop slide, there are no other tall, winding water slides in the Village currently. The new Recreation Center will replace the existing facility at nearly the same location on the site. It is the only public recreation center serving the northern Mount Prospect community. The facility will expand on the programming of the existing Lions Rec Center to include a walking track, (3) basketball courts, and spaces for visual/performing arts, senior/active adults, and preschool/early childhood. While a Use Exception, the preschool/early childhood classroom is compatible with the park, playground, and swimming pool/splash pad uses at Lions Park and will be similar to the preschool/early childhood classroom that currently exists within the Central Community Center. 2. Proposed use exceptions are not of a nature, nor are located, so as to create a detrimental influence in the surrounding properties. The proposed use exceptions are compatible with the residential and institutional uses surrounding the property at Lions Memorial Park. They are not of a nature, nor are they located, to create a detrimental influence on the surrounding properties. Historically, these uses have all been well received by the community and surrounding neighbors and have not been a nuisance to the community. Studies have proven that park and recreational facility improvements have a positive impact on surrounding home values, increasing the market appeal. Property owners are attracted to available open space and recreational amenities in their neighborhoods. Additional information on this topic is available at: https://www.iiparks.org/general/custom.asp?page=PropertyValues 3. Proposed use exceptions shall not represent more than forty percent (40%) of the total floor area. However, in a residential planned unit development area no more than ten percent (10%) of the site area or the total floor area shall be devoted to commercial use. No industrial use shall be permitted within a residential planned unit development.

Emerson Street Mount Prospect, IL 60056 Phone Number: 847.818.5314 Project No: 24003 Re: MPPD Lions Recreation Center & Community Pool Answer the variation standards in 14.203(C) (9) to request relief from the minimum 30' setback requirement for front and exterior side yards. Please write a response to each variation standard. Describe HOW your proposal will meet each standard. Copy this list onto letterhead and then type answers for each point. Standards For Variations: A variation from the regulations of this chapter shall not be granted or recommended for approval by the planning and zoning commission unless findings of fact based on evidence are made in each specific case that affirm the following standards: 1. Because of the particular physical surroundings, shape, or topographical conditions of the specific property involved, a specific hardship to the owner would result, as distinguished from a mere inconvenience if the strict letter of the regulations was to be applied; Throughout the development of the site design, we have carefully considered the placement of all buildings and structures on the site while trying to balance their impact on the surrounding neighborhood and existing park uses. One of the primary site design goals was to provide direct access from the existing parking lot to the existing band shell and playground, as well as the proposed skate park and basketball court, and open park space. This avoids the need for patrons to circulate around the entire building, a major drawback of the current facility. With the desire to maintain a generous and welcoming passageway between the Community Pool and Recreation Center, we feel that the proposed building setback along Lincoln Street of approximately 10'-0" at the northeast corner and increasing to approximately 14'-8" at the northwest corner is appropriate, considering the site constrains we are working with. 2. The conditions upon which an application for a variation are based are unique to the property for which the variation is sought and are not generally applicable to other property within the same zoning classification; The proposed Recreation Center at Lions Park is one of a kind for its area. It is the only public recreation center serving the northern Mount Prospect community. The facility will expand on the programming of the existing Lions Rec Center to include a walking track, (3) basketball courts, spaces for preschool/early childhood, visual/performing arts, and senior/active adults. The 30'-0" setback requirement from Lincoln is very restrictive for a facility of this size based on the existing site constraints. Unlike the modern recreation center planned for Lions Park, uses within C-R districts typically require smaller support facilities within a larger park area, making the setback requirements less restrictive. 3. The purpose of the variation is not based primarily upon a desire to increase financial gain; Financial gain was not a driving factor regarding the overall site design for Lions Park. The variation to the 30' building setback on Lincoln Street is necessary for the purpose of making the best design and functionality decisions for the neighborhood and the overall positive impact for the community. The goal of the Rec Center, Community Pool, and site related improvements (6 pickleball courts, skate plaza, basketball court, and outdoor game area), was to integrate with the existing uses on site (parking lot, memorial, bandshell, playground, tennis courts, baseball fields, walking path system, and open space) and provide direct access from the parking lot to the entire park via a generous and welcoming passageway between the pool building and recreation center, a.k.a. "the gateway to the park." 4. The alleged difficulty or hardship is caused by this chapter and has not been created by any person presently having an interest in the property; The hardship related to the 30' building setback requirement has not been created by any person presently having an interest in the property. The property has been owned by the Mt. Prospect Park District for nearly 70 years. Throughout the years, the Park District has continued to make improvements to the site and is committed to continuing to provide a wide variety of programming, special events, and recreational opportunities at Lions Memorial Park- both indoors and outdoors, for years to come. 5. The granting of the variation will not be detrimental to the public welfare or injurious to other property or improvements in the neighborhood in which the property is located; Contrary to being detrimental to the public welfare or injurious to other property or improvements in the neighborhood, Mt. Prospect Park District's Lion's Park project will enhance recreational opportunities within the limits of Lions Park including building a new recreational facility, community pool, and site related improvements. The park and recreation center can help enhance public health and reduce stress by promoting physical activity including walking, visual and performing arts, sports, and many other programming opportunities. In addition, the welcoming passageway between the pool building and recreation center will also serve as fire truck access around the new facility. 6. The granting of the variation will not alter the essential character of the neighborhood; and The Mt. Prospect Park District will enhance and develop the property within its own parcel limits. The Park is existing, and the proposed new uses are compatible with the residential and institutional uses surrounding the property at Lions Memorial Park. Historically, these amenities have all been well received by the community and surrounding neighbors and have not been a nuisance to the community. The existing rec center does not presently comply with the 30' setback requirement; therefore, the proposed setback for the new facility will not alter the essential character of the neighborhood in that regard. 7. The proposed variation will not impair an adequate supply of light and air to adjacent property or substantially increase the congestion of the public streets, or increase the danger of fire, or impair natural drainage or create drainage problems on adjacent properties, or endanger the public safety, or substantially diminish or impair property values within the neighborhood. The open park space improves air quality. Specifically on the north side of the building along Lincoln St., there will be a mixture of ornamental trees, shrubs, and other perennials. The proposed improvements will have misters and drip irrigation to enhance the growth and quality of the plantings. This is an improvement over the landscape along the north elevation of the existing facility which is limited to some plantings at the northwest corner of the building and a few trees along the building's length. The building setback from Lincoln will not increase the congestion on that street. A parking study has been conducted and the Village's questions and concerns regarding parking will be responded to with this letter. The proposed building setbacks allow for adequate circulation around the building and into the park, including fire truck access around the new rec center, something that the current facility does not have. The open park space also improves water quality by absorbing rainwater and providing natural drainage. A Stormwater Management Report and plans have already been submitted to the Village of Mount Prospect and will be submitted to the Metropolitan Water Reclamation District (MWRD) to ensure all necessary utilities and stormwater requirements are met. Finally, studies have proven that park and recreational facility improvements have a positive impact on surrounding home values, increasing the market appeal. Property owners are attracted to available open space and recreational amenities in their neighborhoods.

Emerson Street Mount Prospect, IL 60056 Phone Number: 847.818.5314 Project No: 24003 Re: MPPD Lions Recreation Center & Community Pool Following is a list of itemized responses to the Concept Plan Review Comments dated March 25, 2025, received from the Village. Items to be Addressed Prior to Planning and Zoning Hearing PLANNING AND ZONING DIVISION Land Use 1. Provide a table with a list of amenities / uses and proposed hours of operation for each. The table can be modeled from the uses listed in the parking study tables 1 and 2. Response: A Lions Memorial Park Land Use Table including existing and proposed site amenities, the proposed hours of operation, and whether or not the amenity is illuminated by site lighting has been provided. Bulk Regulations 2. Mark the setback of the primary building from Lincoln Street on the site plan. It is indicated in the zoning table already. Response: The setback distance of the Rec Center from the lot line along Lincoln Street has been added to the site plan. 3. Please double-check the lot coverage calculation - 70% seems high for the lot coverage across the two parcels. Response: Our previous calculation was incorrect. The site plan has been revised to indicate approximately 337o impervious area coverage. 4. Downtown Design Guidelines a. The north fapade of the proposed recreation center does not satisfy the Village's downtown design guidelines. Given the visible nature of this elevation, that it is less than 10' from the property line, and that it is across the street from attached single family homes, these guidelines must be satisfied. i. Linear Massing: The recreation center is 202' long on Lincoln Street. Please vary the depth of the structure by way of recesses and projection within the building's architecture. Response: To break up the visual expanse of the facade and vary the depth we have provided additional 12-foot-wide curtainwall window "arcades" spaced along entire length of fapade, that project approximately 12" from the face of precast and extend the full height of building. These curtain walls use a combination of clear vision glass, spandrel glass, and wood -tone metal panel infills as well as curtain wall integrated sunshades to add visual interest. ii. Windows & Doors: Only -10% of north fapade is windows, 25% is required. Incorporate faux windows that inset on the 1 st floor, or add real windows on the 2nd floor, where they will not interfere with the interior programming (gym space). Response: The curtainwall area has been increased to approximately 2817o of the fapade by incorporating additional window "arcades" with spandrel glass at the first floor and clear vision glass at the second floor. iii. Vertical Massing: Provide more vertical incorporation of materials to reduce contrast between the first and second floor division. Response: We have incorporated additional vertical curtainwall "arcades" to break up the vertical massing. The curtainwall system incorporates a combination of clear glass, spandrel glass, and wood tone metal panel infill to further reduce the contrast between the first and second floor. In addition, the grade elevation along the entire north fapade will slope up to nearly meet the finished floor elevation to reduce the vertical appearance of the fapade. iv. All loading areas shall be hidden from street view or from adjacent residential areas. All motor vehicle loading berths abutting residential areas shall be screened by building walls, or by a uniformly painted solid noncombustible fence, wall, or door, or densely planted mature shrubbery or any combination thereof, not less than six feet (6) in height. Such required screening shall be immediately adjacent to the loading area and in addition to transitional screening requirements elsewhere in this chapter. In all districts, no loading berths shall be located in a required front, corner side or side yard. Loading berths located in a required rear yard may be open to the sky. 1. Evaluate relocating the loading berth to the interior of the site so that it may be accessed from the parking lot. If not possible, investigate if rotating the loading berth so that it does not face the street is feasible, or provide additional architectural interest in this area and/or screening. STUDIO 222 ARC[ 111 ECTS 0 Response: The loading area will be screened with a decorative solid panel 6-foot-tall sliding gate. See revised north elevation. b. Materials: Provide material boards, material samples, and material schedules for all proposed structures. Response: We are in the process of gathering material samples and will bring sample boards to Plan Commission and Village Board meetings. 5. General Design Guidelines a. Will there be roof -mounted mechanical equipment on any of the accessory structures? If so, provide sight line diagrams for the accessory buildings demonstrating that additional rooftop screening is not necessary. Response: There will be roof -mounted mechanical equipment on the Bathhouse only. A sight line diagram for the Bathhouse has been provided. Accessory Structures 6. Provide a table of all vertical accessory structures and list the height of each. (Fence heights will be discussed separately). Example table is provided. Response: See table below. For the transformers, the size will be dictated by ComEd, but the range will most likely be 56" to 70". 70" is worst case, but the Electrical Engineer believes it will be more like 56". Please note that these estimates include the 6" thickness for the concrete pad.

Provide a fence site plan showing the location of the proposed fences and a table with fence descriptions. Response: Sheet LS-105 is a site fence plan that shows the location of said fence types, created a schedule, and associated fence details are on Sheet LS-502. 14. Pickle ball courts proposal includes 4' and 6' black vinyl coated chain link fence with windscreens. Provide a detail of the proposed windscreens, including material and color. Note, the wind screens shall not display any logos or signage. Response: Sheet LS-105 contains a cut sheet on the proposed windscreens. It will not contain any logos or signage. STUDIO 222ARC[ IICLC75 0 Off -Street Parking Requirements 15. Staff reviewed the Parking Study Memorandum prepared by Eriksson Engineering Associates Ltd (EEA) and dated May 20, 2025. The parking study suggests that 1,257 spaces are required by code, and the proposed on -site parking is 185 spaces, resulting in a parking deficit of 1,072 spaces. Staff has the following comments on the parking calculations: a. Table 3 Lions Center Parking Requirements i. The proposed gym is approximately 20,000 SF and has a maximum capacity of 1,200 people, however the study notes that the Park District does not intend to have more than 200 people use the gym at one time. Please clarify the intended use of the gym. Staff would use the "gym/health club" parking calculation in lieu of the "arena/stadium" parking calculation if the gym will have a maximum capacity of 200 people. Response: The District does not intend to have more than 250 persons (revised) in the gym at one time. The parking calculations were revised as noted. ii. The proposed preschool is one classroom with 10 students and 1 teacher. Staff would consider this an accessory use to the recreation center and would use the "gym/health club" parking calculation in lieu of the "daycare" parking calculation. Staff would include provisions in the PUD approval that would require PUD amendment if the preschool were to expand in size. Response: The parking calculations were revised as noted. iii. Staff agrees with using "gym/health club" parking calculations for the other rooms in the recreation center (multi -purpose, dance studio, staff, art studio, track, multigenerational). Response: Comment noted. b. Table 4 Lions Memorial Park Parking Requirements i. The table indicates 37,840 SF for the community pool. Please provide a plan page showing which pool areas / structures are included in this number. Response: Table indicating "Area of Community Pool for Parking Calculations" has been added to Sheet A0.02 Site Plan. It lists the pool areas/structures included in the number. The area has been updated from the last PUD submittal to 38,054 SF. ii. Please include any relevant notes about the seasonal ice rink in Table 4. Response: The ice ring will be 3,450 square feet accommodating 46 skaters. 16. The parking study suggested a heavy dependence on on -street parking to meet the minimum parking requirements. a. Staff requests that the petitioner explore off -site parking agreements with the following locations to secure additional off-street parking: i. Dasom Community Church (501 S Emerson St) STUDIO 222 ARC[ IIIECTS 0 ii. Busse Automotive (1 13 E Prospect Ave) iii. Maple Street Parking Deck (303 S Maple St) Response: The Park District is in communication with both Dasom Community Church and Busse Automotive to identify off -site parking arrangements. Staff hosted Dasom Community Church for a meeting on July 16th which explored parking arrangements for park visitors to utilize both Church's parking lots (main lot and separate lot to the north, around 60 spaces in total) on days/times that do not conflict with Church operations (mainly Monday through Saturday). These lots are particularly well placed for the users of the tennis/pickleball courts and ballfields. The Park District is in the process of assessing the existing conditions of both lots and will be drafting an agreement for consideration of both parties. Currently, the Park District's focus for Busse Automotive is for additional parking during concerts and/or special events. The Maple Street Parking Deck will also be available for Park District patrons (within the existing parameters of the Deck - 40 free spaces available w/4 hour time limit, 222 spaces for commuters Monday -Friday until 6PM). The Parking Deck is particularly well -placed for the Summer Concert Series, with concerts taking place in the evenings after commuter hours, as well as weekend demands of the facility. Additionally, the Park District is planning to add around 15 parking stalls to the existing lot, bringing the total number of stalls onsite to 200. b. Staff requests that the petitioner include a land bank provision to convert some or all of the tennis courts into a parking lot should future parking demand exceed what is provided. Response: During a meeting between the Park District and Village on July 15th, alternatives to the tennis court land bank were proposed including angular/off-street parking on Maple adjacent to the tennis courts, and eastward angular/off-street on Lincoln. Both would provide additional parking opportunities for visitors to the park, with stalls on Maple well -placed for courts/pool visitors, and the stalls on Maple Lincoln well -placed for concerts/park visitors (with the added benefit of providing space for food trucks, etc.). The tennis courts at Lions Memorial Park are well -utilized, so these alternatives would provide additional parking, if needed, while maintaining the courts. 17. The comparable recreational facilities provided in the Parking Study Memorandum by EEA are roughly half the maximum capacity of Lions Park. Staff requests that the petitioner provide parking information on two other recreational facilities: a. Wheeling Park District, which includes a family aquatic center, because this facility more closely resembles what is proposed; and Response: Three attempts to contact WPD have not been successful. Staff have instead focused on comparable sites for Arlington Heights Park District, as well as the most directly -comparable MPPD-owned site, RecPlex. b. RecPlex in Mount Prospect. Response: Data added. STUDIO 222 ARC[ 111 ECTS 0 18. Provide schedule of annual events / activities / leagues, with estimated number of participants and maximum number of participants. Response: The maximum number of participants has been included in the revised parking study. For the schedule of annual events, we have included the breakouts below as a general guideline (from the Park District's 2025 Referendum page). In addition, following is a link to the Park District's historical brochures for more details: h- s://www.rn door / arlk... fistrli .:1::::i,i to ping, irair ,,.auiides/. • Athletics (Gymnasium) o Youth/adult basketball leagues and tournaments o Pickleball - indoor and outdoor open play, leagues, and tournaments o Other sports programming o After -school gym classes o Open gym • Performing Arts o Dance programming o Rehearsal space for Mt.

Provide a Parking Management Plan detailing parking accommodations for day-to-day activities, demonstrating adequate parking for the facility exists largely on -site. If there is a projected shortage of parking provided onsite for day-to-day activities, please estimate that number and provide solutions to this shortage. Response: A Parking Management Plan showing the Estimated Seasonal Use of the Lions Park Facilities has been added to the appendix of the revised parking study. The summary provided is the Park District's best guess for day-to-day operations, taking into account seasonal/daytime variations. 20. Provide a Special Event Parking Plan detailing additional off -site parking to be provided on nearby properties via off -site parking agreements, on -street parking, and provide information on how parking is facilitated the day of special events. Response: For the Summer Concert Series and other special events where parking needs are anticipated to exceed available, onsite parking, the Park District's goal will be to direct visitors to the Maple Street Parking Deck (within the parameters of the Deck, as noted above), as well the parking lots of our community partners that are actively being engaged. Additional opportunities exist to utilize parking spaces on Prospect Ave outside of dedicated commuter hours. STUDIO 222 ARC[ IICECTS 21. Staff is likely to include an ongoing monitoring and reporting provision as a condition of approval for the PUD due to the projected parking shortage. Response: The Park District agrees to reevaluate the sufficiency of onsite parking after construction, in cooperation with the Village. Landscape Plan Content 22. Update the landscape plans to show the path on the east side of the pool house. Response: The path has been added. 23. Use plan callouts or drawing tools to better differentiate the proposed landscaping from the existing landscaping to remain. Response: Sheet LP-100 has been updated with all proposed landscaping colored for graphic clarity. Site Landscaping 24. Staff requests additional landscaping in the parking lot landscape islands to bring it closer to compliance with landscape code requirements. Response: An additional 19 shade trees have been added to the parking lot, mainly in the islands. 25. Add landscape screening on the south side of the proposed skate park and basketball court to better screen these uses from the detached single-family homes to the south. Response: An additional 8 evergreen trees have been added to provide landscape screening. Regarding the reasons for the proposed location of the skate park and basketball, the proximity of the available street parking provides convenient and direct access to the skate plaza for those planning to use a skateboard. Per Mt. Prospect Park District Ordinance 525, the use of Skateboards are not intended for use on any District Property. Such devices are permitted only by written authorization or where specifically designated by signage or rule. Even if permitted in a designated area, no person shall interfere with pedestrian -use of sidewalks or Vehicle -use of the streets or otherwise act negligently, recklessly or without due caution, or in any manner so as to endanger any Person or property. Additionally, the proposed location is relatively flat and buildable, which allows for sheet flow drainage and eliminates the need for underdrains. The northern area has many mature trees that would require removal. Having either of these amenities near these trees would pose challenges with landscape debris. Ultimately, this would have a negative impact for the end user using either amenity. Lastly, moving the basketball court and skate plaza even further north, to avoid any impact on the trees, would encroach on the available green space, which is used regularly for programming and special events at the bandshell. STUDIO 222 ARC[ 111 ECTS 0 Please note these site amenities are being bid as Alternates and may not be constructed as part of this project. Foundation Landscaping 26. Increase foundation landscaping on the north side of the recreation center. Response: The landscape plantings have been significantly increased with a focus on vertical height in response to the scale of the proposed architectural facade. Responses to Code Standards 27. Correct the May 2007 date in the phasing plan. Response: Following is the proposed project timeline. Regarding construction phasing, building and site demolition will commence first, followed by new building construction for the Rec Center, Pool Buildings, and Pool. • Project Design & Permitting Summer/Fall 2025 • Project Bidding August/September 2025 • Park District Board Approval October 15, 2025 • Demolition of Big Surf & Lions Recreation Center October/November 2025 Starts • Substantial Completion for Lions Park May 2027 Improvements, Community Center and Pool 28. Answer the variation standards in 14.203(C) (9) to request relief from the minimum 30' setback requirement for front and exterior side yards. Response: Letter requesting relief from the minimum 30' setback requirement has been provided. 29. Answer the code exceptions standards in 15.109 to request relief from the stormwater detention requirements. Response: Code exception standards are provided under separate cover. Signs 30. The freestanding sign shall be located outside of the sight triangle. Such triangle shall have legs of 10' along the property lines where two streets intersect. Response: The freestanding signs will replace the (2) existing freestanding signs in their current location, which is well outside the extents of the 10' sight triangle. See sight triangles added to updated A0.02 Site Plan. 31. Any future relief requested for signage shall require an application for a minor amendment to the PUD. Response: Comment noted. 32. See windscreen comment under "Fences and Walls." Response: See response under "Fences and Walls." STUDIO 222 ARC[ IIILCTS 0 Public Works 33. Sections 15.401.13 and 15.402.13 of the Village Code require that the entire site be brought into compliance with current stormwater management standards when a new building is constructed. Staff concurs that this Code requirement would place a severe hardship on the proposed development. Staff further concurs that the proposed development as proposed would provide significant stormwater management benefits to the watershed where currently none exist. However, it should be clearly stated in any conditions of approval for the PUD that a code exception is being requested as part of the PUD to only provide stormwater detention for the areas to be developed. PW has no objection to this requested code exception. Response: Noted, the code exception is being formally requested and Exception Standards provided accordingly. Please note that as discussed with Village staff, there have been additional minor adjustments to the parking lot area that increase the stormwater management requirements. The stormwater calculations, exhibits, and permit applications have been updated accordingly. 34. The stormwater runoff from the existing parking lot will be redirected through the proposed detention pond and treated as bypass flow. No additional storage volume will be added to accommodate this flow, so the pond will fill and overflow for storm events smaller than the 100-year design storm. As requested previously, provide calculations including flows from all areas tributary to the pond to determine at what storm frequency the pond would be expected to fill and overflow. Response: The requested additional stormwater calculations were previously provided under separate cover and have been uploaded to the Village portal for review. Per the results of this analysis, the proposed improvements would be able to accommodate between the 10 and 25-year event prior to overflows occurring. Items to be Addressed Prior to Building Permit Submittal Response: Planning and Zoning, Building, and Fire Department comments (1-17) have been noted and will be addressed prior to building permit submittal. Public Works 18. The Village still sees value to keeping/providing pedestrian access from Lincoln Street, along the west side of the new building to the main entrance. We strongly recommend (but are not requiring) keeping/providing this pedestrian access. Response: The nature of the grade change in this area in existing conditions makes it nearly impossible to provide an ADA compliant public sidewalk connection in this area. There is a carriage walk in this area to help accommodate drop off and pick up maneuvers, but there is no readily feasible way to provide a safe and compliant connection to existing public walk elevations in Lincoln St. 19. Add crosswalk striping across the existing parking lot drive aisles. Response: Crosswalk striping has been added at all pedestrian crossings in the lot. STUDIO 222 ARC[ IICLCTS 0 20. Show the connection of the proposed water fountain to the water supply. Response: Schematic water service routing to the drinking fountain is included on the Civil plans. This scope is detailed and will be installed by site plumbing contractor and not directly part of Civil scope. 21. Confirm geometry of the proposed overflow weir. The width, surface, and high water level do not seem consistent with the weir location noted on Sheet C402. Response: The overflow geometry for both the existing and proposed basins has been reviewed and confirmed to be accurate with the design intent. The existing basin is to have a 20'+/- overflow width that is primarily in pavement with a base spill of 659.40 per As -Built information. The proposed basin has a 48' +/- wide overflow, which is generally the western edge of the site, where water begins spilling to the Sha-Bonee Trail ROW at 655.80. This is consistent with the information included on C402 and C602.

Emerson Street Mount Prospect, IL 60056 Phone Number: 847.818.5314 Project No: 24003 Re: MPPD Lions Recreation Center & Community Pool Following is a list of itemized responses to the Village Review #5 Comments dated August 8, 2025, received from the Village. Items to be addressed at or before the Planning and Zoning Commission Meeting 8114125: Public Works 1. What steps will be taken to direct overflow parking to the Maple Street parking deck? Response: The Park District will outline parking accommodations on its website, including the operating guidelines of the Maple Street parking deck, with additional direction posted via signage/sandwich boards on the days of concerts and/or special events where the need for overflow parking is anticipated. The Park District is working toward partnerships with the owners of nearby parking lots to further supplement the overflow spaces provided by the parking deck, with the goal of easing the need for on -street parking. 2. The study refers to 677 on -street parking spaces on "other streets". These spaces should not be considered for regular activities and events as it would be disruptive to the neighborhood. Off-street parking should be utilized as much as possible. At what times does the Park District anticipate needing "other streets" for parking? What steps will be taken to minimize parking on these "other streets"? Response: In general, parking needs are not anticipated to regularly surpass available parking spaces during spring, fall, and winter seasons (as outlined on Page 11 of the Parking Study, right -most column) outside of pre -planned special events, such as a "Fall Fest" or the like on a Saturday from 8:00 AM - 2:00 PM, for example. As noted above, the Park District will continue to work toward partnerships for overflow parking and detail this information on its website, once completed. The summer season is anticipated to be the highest parking demand, most particularly for the Summer Concert Series at the Lions Memorial Park Bandshell (with Thursdays historically being the highest demand): • Monday evenings (Community Band) - Parking demand highest from approximately 7:30-8:30 PM • Thursday evenings (Concerts) - Parking demand highest from approximately 7:00- 9:30 PM Regarding summer operations, the new community pool and recreation centers will have concurrent activity where parking needs could surpass available parking spaces at certain times. Although programming details will be developed in the coming year, upon completion the Park District will monitor demand and consider possible adjustments to scheduling during peak times. The Park District will work with the Village to identify opportunities should future parking demand warrant additional spaces. Items to be addressed prior to Village Board Meeting 912125: Planning & Zoning Division 3. Please make the following minor corrections in the narrative letter dated July 21, 2025, and prepared by Studio 222 Architects: a. Page 1 1 under 16b, change the street name from Maple to Lincoln ("the stalls on Lincoln are well -placed for concerts/park visitors") b. Page 12, spell out "NWSRA" Response: An updated Review Letter #1 response with a revised date of 2025-08-11 has been provided correcting the two items noted above. 4. Update the PUD response letter dated May 28, 2025, and prepared by the Mt Prospect Park District. Some of the responses reference old plans. a. General Standards: Update the responses to the general standards to reflect the changes made to the plans and elevations.

Other Exceptions: Update the responses to the other exceptions to respond to each standard 1 through 5 separately. It appears all standards are answered but the bullets just need to be rearranged. Also update the impervious area numbers. Response: An updated PUD response letter dated August 11th, 2025, addressing 4a & 4c has been provided. 5. Please make the following minor corrections to the Parking Study dated May 20, Revised July 21, 2025, and prepared by EEA: a. Page 3, Table 1: The total square footage of the recreation center should be 55,700 SF (not 15,700 SF). Response: The total square footage has been corrected in the revised Parking Study dated August 11, 2025. b. Please check that the Maple Street Deck parking stall numbers are 262 throughout the parking study document. Response: The Maple Street Deck count has been updated to 262 spaces on page 7 of 16. In Table 12 on page 9 of 16, the count shown is 262 spaces - occupied spaces = 236 spaces available for the District to use. In the plan set on page A0.02 Site Plan, the recreation center floor area is listed as 35,616 SF, while elsewhere the recreation center is listed as 55,700 SF. Please explain the discrepancy. Response: The total square footage of the Rec Center (10 & 2nd Floors) is 55,700 SF. On A0.02 Site Plan, we were calculating lot coverage, so only the square footage of the 1 st Floor is shown (35,616 SF) in that table.

Corcoran, P.E., PTOE Director of Traffic Engineering DATE: May 20, 2025 Revised August 11, 2025 RE: Lions Recreation Center and Memorial Park Parking Study 411 South Maple Street Mount Prospect, Illinois 0'04�4 ERIKSSON ENGINEERING A59DCIATE5, LTD, This memorandum summarizes the results of a parking study for Lions Recreation Center and Memorial Park located at 411 South Maple Street in Mt. Prospect, Illinois. This parking analysis was done on behalf of the Mount Prospect Park District and Nicholas and Associates at the request of the Village of Mt Prospect as part of their review process. During the study, Eriksson Engineering Associates (EEA) collected information on the existing and proposed park's recreation facilities and parking spaces, determined the parking required by the Mt. Prospect Zoning Code, and estimated the amount of parking used and needed. Site Location Lions Recreation Center and Memorial Park are located at 411 South Maple Street on a 24-acre site in Mt. Prospect, Illinois. It is bounded by Lincoln Street to the north, Williams and School Streets to the east, Shabonee Trail, Moehling Drive, and Lions Park Elementary School to the south, and Maple Street to the west. It is in a residential neighborhood with multi -family buildings to the north and northeast and single- family homes to the east, south, and west. Lions Park Elementary School is located to the south. Figure 1 shows the location of the park and surrounding uses and roads. Proposed Changes The Mt. Prospect Park District will replace the existing recreational center building with a new 55,700 square foot building. It will have a gymnasium, art and dance studios, multi -purpose and multi -generational rooms, a running track, and a pre-school. Table 1 summarizes the uses within the existing and proposed buildings and their maximum occupancies. The new gymnasium has a capacity for 1,200 persons but the District will limit its use to a maximum of 250 persons based on programing. The new recreational center will accommodate less people than the current building (523 vs. 589). Outside, the district will replace the existing surf pool with a new community pool, and add a skate park, a basketball court, and pickleball courts to the existing uses at the park. Table 2 shows the proposed changes for the park. Overall, the capacity of all the outside uses increases 21 % from 1,640 to 1,990 persons. Municipal Parking Requirements EEA reviewed the Mt Prospect Zoning Code and the proposed use of the park with the new recreation center and outside facilities. Tables 3 and 4 summarize the parking requirements for the recreational building and for the park. The overall parking requirement for the site is 1,070 spaces (Table 5).

In reality, this situation does not occur. National and Local Parking Surveys EEA reviewed the national parking data for recreation centers and parks found in the Institute of Transportation Engineers Parking Generation Manual, 6t" Edition. Table 6 summarizes ITE parking demand results for the recreation center (Land Use Code 495) of 100 vehicles. Thiis is significantly less than the zoning requirement of 279 spaces. A recent parking study at the Arlington Ridge Recreation Center in Arlington Heights (89,265 square feet) found the peak demand on a Saturday was 1.47 vehicles per 1,000 square feet. Using this rate for the proposed building would generate 82 parked vehicles. The parking supply at the Mt. Prospect Park District Rec Plex was also reviewed and compared to its building size. The 93,000 square foot building has 384 parking spaces or 4.1 spaces per 1,000 square feet. Please note that the Rec Plex has an indoor pool which will increase its parking supply. Table 6 Lions Recreation Center Parking Comparison Source Total Demand Mt. Prospect Zoning Code 279 ITE Parking Data 100 Arlington Ridge Center 82 MPPD Rec Plex 228 The ITE does not have a full set of data for all the outdoor uses at the park so a combination of ITE data, local surveys, and projected occupancy rates were used to estimate the outside activities demand. Pool parking was estimated from data EEA has from work with the Arlington Heights Park District on Frontier Park and Camelot Park pools. Parking data found the Frontier Park demand was 0.32 vehicles per bather and 0.10 vehicles per bather for Camelot Park. Camelot Park demand rate is lower since it is located in the middle of a large residential neighborhood allowing more walking and biking usage. Frontier Park is located on the edge of one neighborhood resulting in more driving. The more conservative value of 0.32 was used. The tennis and pickleball courts were based on LUC 490 Tennis Club which contained only one survey on a Saturday. This data was used and is slightly higher than the village requirement. The remaining uses were based on the village code. Table 7 shows the demand of the outside activities could be 453 vehicles, based on all activities occurring at the same time at maximum occupancy. Table 8 shows the total demand at 553 vehicles which is 55% less than the code calculations. Iflhiunols III Wisconsin I Indiana www e+ea 1fdLcowi �:15 Carurrrru°rraa uu e 11'. ir'iiva.

In the appendix, the Mount Park District provided an estimated usage by the number of attendees and parked vehicles for various time of day and season. The parking demand ranged from 154 vehicles to 612 vehicles on a Thursday concert at the bandshell. Most large recreation centers and parks have similar situations with a large maximum capacity not needing all the required parking spaces. EEA compared Lions Park with three large Arlington Park District parks and compared their maximum capacity to the nearby available parking. Table 9 shows that park name, maximum capacity, and the available parking on -site, adjacent on -street, and other available parking. Lions Park provides similar or more parking than the three other parks in the area. Iflhiunols III Wisconsin I Indiana www e+ea 1fdLcowi �:15 Carurrrru°rraa uu e 11'. ir'iiva.

It has 173 regular and 6 accessible parking spaces for a total of 179 on -site parking spaces. With the proposed improvements, it will have 194 regular and 6 accessible parking spaces for a total of 200 on- stie parking spaces. A total of 1,070 parking spaces are required by the Mt. Prospect Zoning Code which exceeds the number of on -site parking spaces. Any available on -street or garage parking nearby cannot be counted toward the zoning requirement. A parking variation of 870 spaces will be needed. Providing an additional 870 parking spaces at the park would need about six acres of pavement which world significantly increase storm water runoff and decrease landscaping/green areas. Also, program areas would need to be removed in order to provide a larger parking lot. There are available public parking areas nearby on -street, at Lions Park Elementary School, and at the Maple Street Parking Garage that could accommodate park parking without constructing bigger lots. Lions Park Elementary School The school immediately south of the park has two parking lots with a total of 93 spaces including 6 accessible spaces. The Mt. Prospect Park District and School District 57 does have an intergovernmental agreement the use each other's parking lots. These school parking lots are primarily used for the baseball fields and for overflow parking at the pool. Maple Street Parking Deck The Maple Street parking deck is located north of Dawson Drive between Maple and Elm Streets. It has 262 spaces. Other Off-street Parking Opportunities The District is exploring agreements for off-street parking agreements at Dasom Community Church (30- 50 spaces) and Busse Automotive (50-75 spaces) for additional parking. On -Street Parking Lions Park parking inventory area is bounded by Prospect Avenue to the north, Louis Street to the east, Council Trail to the south, and Emerson Street to the west. Land uses around the site consist of an apartment complex to the north, an apartment complex and single-family homes to the east, Lions Park Elementary School and single-family homes to the south, and single-family homes to the west.

Prospect Park District (MPPD), and located at 411 S Maple St in Mt. Prospect. The existing 20.8 (±) acre site is bounded by residential properties on all sides, as well as Lions Elementary School to the South. The site is primarily bordered by single-family residential properties. The site is under the Metropolitan Water Reclamation District of Greater Chicago's Watershed Management Ordinance and the Village of Mt. Prospect's Municipal Code. EXISTING CONDITIONS The existing site consists of a public recreation building and outdoor pool facility with supporting infrastructure, including parking lot and pathways. Additionally, there are existing Veteran's Memorial Garden and Bandshell improvements on -site. The site also provides various recreational facilities, including walking paths, playground facilities, and valuable open space for flexible programming needs for the park district. Recent improvements on -site include the construction of the new playground and path facilities in summer of 2024. In general, the site slopes to the southeast and drains to the existing village storm sewer infrastructure that traverses the site. In general, stormwater overflow routes from the site spill southwest towards Sha-Bonee Trail ROW in the event that local sewer capacity is exceeded. There are Village sewers that traverse the site in existing conditions. This includes a 24" storm sewer that discharges to Weller Creek, and a 90" combined sewer that discharges to an MWRD interceptor that run N/Sthrough the site, as well as an existing 24" combined sewer that runs E/W before connecting to Village infrastructure in Sha-Bonee Trail. There are notable portions of green space in existing conditions, particularly in the southwest and eastern portions of the site, that will be remain as such and are well outside the proposed improvements. There are two existing stormwater management areas on -site per record information from the MWRD. This includes the basin installed in 2024 in the area of the previous playground under WMO 23-0277, as well a small stormwater system to meet MWRD requirements during the memorial garden improvements under SPO 12-0060. There will be slight impacts to the SPO 12-0060 stormwater area, as discussed further in the proposed conditions, but in general, the improvements will have minimal impacts on existing stormwater management facilities. Sanitary flows are conveyed to Village combined sewer infrastructure located in Lincoln St as well as the existing 24" combined sewer that traverses the site. This includes sanitary connections for the Recreation Building and Bathhouse Building, as well as a dedicated sanitary service for the filter backwash discharge at the Mechanical Building. I]:T6Il81.19 ZeLeL101kIIs] 0 The proposed project consists of the demolition of the existing public recreation building and outdoor pool facility and construction of new, replacement facilities. The overall character and function of the site will not be impacted as a result of the improvements. In addition to the rec building and aquatic facilities, various recreational facilities are also proposed, including a new skate park, outdoor basketball courts and various pathway and plaza area improvements. The existing parking lot is to be milled and overlaid and is considered Non -Qualified Development. The parking lot will also be routed through the proposed stormwater management system, although it is not required to do, providing a watershed benefit to the area. These improvements were discussed with the MWRD during the Pre -Application meeting, who is in agreement that the parking lot storm sewer improvements can also be excluded from the Qualified Development Area, as these improvements are considered re-routing and do not impact ultimate receiving sewer. All tributary areas are appropriately accounted for in the overflow calculations. The proposed improvements will result in approximately 3.86 Acres of total Qualified Development Area. Stormwater improvements are to be provided for all Development areas on site per MWRD requirements. Portions of the site are excluded from the qualified development area, as they will not be disturbed or are considered maintenance and/or open space development, all of which are non -qualified improvements. This includes extensive portions of green space, including the ballfields, that will not be disturbed, as well as portions of existing parking lot and court improvements that are to remain without changing drainage characteristics. The majority of the Qualified Development Area is located in the vicinity of the pool and rec building improvements. However, there are also additional improvements that are more isolated that are also considered Qualified Development Area. This includes the skate park improvements as well as the asphalt basketball court. The skate park area is readily tributary to the Phase 1 detention basin installed under WMO 23-0277, and this basin can handle the additional storage volume without significant impact to the original design. The basketball area will drain to green space on -site and is not immediately tributary to a stormwater management system. However, there is extensive "Trade -Off" area available due to the existing parking lot being detained, meaning that this area does not need to be considered as Undetained Development Area. A small portion of the proposed improvements overlaps with the SPO 12-0060 Detention Service Area and may also have a slight impact on the provided volume per the record design. To account for this, the team proposes to leave all existing storage and corresponding infrastructure in place, while also adding the previously required detention volume to the Phase 2 required storage; that is, the required storage volume is the SPO Volume + New Volume for Development Area. Additionally, the storm sewer downstream of the existing system is to be routed through the proposed basin, meaning that the areas are also hydrologically connected. To determine the required detention volumes, the MWRD Nomograph was utilized. Two sets of calculations are included. The first speaks to all of the development area tributary to the new, east basin, which is the majority of the site improvements. Per the Nomograph, the required storage is 1.417 Acre -Ft. With the additional SPO volume, the total required storage for the east basin is 1.472 Acre -Ft. This storage is to be provided in an approximately 22,500 SF detention basin located near the eastern portion of the site. The basin is to be 5' deep and include 12" of ponding beneath the outlet pipe in order to meet MWRD Volume Control requirements. The pond is to have 4:1 side slopes with an underdrain at the bottom to help dewater the area over time. The basin, as well as the adjacent green space, will be native planted. Volume Control for the entirety of the improvements will be met through the east basin. The existing parking lot trade off area will more than account for any of the proposed impervious area that is not intended to be directly tributary to the stormwater management system. Additionally, a Nomograph Calculation was prepared just for the Skate Park area, which is tributary the Phase 1 basin. This is considered a Redevelopment by the MWRD, and will require a Schedule D Legacy. The approximate additional detention storage required is 0.079 Acre -Ft. The Phase 1 required storage is 0.174 Acre -Ft, meaning the new required storage is 0.253 Acre -Ft. To meet this required storage in the current basin, the HWL will increase by approximately 8" from the approved As -Built conditions. In general, all stormwater storage on -site is to be provided in surface detention basins. All stormwater flows will discharge to the Village 24" separate storm sewer that outfalls to Weller Creek. The proposed storm sewers will be sized to convey the 100-year rainfall event without surcharging above grade. Stormwater overflows generally convey to the south towards Sha-Bonee Trail ROW. All overflow elevations are well below existing or proposed Finished Floor Elevations in the vicinity of the site. Non -Qualified Development Areas, which include maintenance and appropriate open space activities, are excluded from the Development Area in accordance with MWRD requirements. METHODOLOGY In order to determine the detention requirements on site, the MWRD Bulletin 75 Nomograph was used. For the primary development area, the allowable release rate for the site was determined by looking at the Qualified Development Area (3.73 Acres). The site falls within the Des Plaines River watershed, with an assigned allowable release rate of 0.20 cfs/acre. Per the results of the Nomograph utilizing the Reduced Curve Number, the required detention storage in the final conditions is 1.417 acre-ft for the east basin. Additionally, the SPO required volume (0.055 ac-ft) will also be added to the storage for this area. The total required detention storage for the east basin is thus 1.472 Acre -Ft. The required storage is to be provided in 5' deep surface basin located on the eastern portion of the site. The designed HWL of the system is 655.20, where 1.472 Acre -Ft of storage is provided. Per WMO 23-0277, the required detention storage is 0.174 Acre -Ft, and per the Skate Park Nomograph calculations, an additional 0.079 Acre -Ft of storage is required, for a total of 0.253 Acre -Ft of storage. The Actual Release Rate used in the Skate Park Nomograph calculations is the approximated additional flow through the Phase 1 vortex restrictor at the newly proposed HWL. The new HWL results in an additional peak discharge of 0.008 cfs which is utilized in the Nomograph calcaultions. With the currently installed vortex restrictor, the actual release rate of 0.098 cfs is notably less than the allowable of 0.116 cfs, meaning the required storage volumes and release rates are in compliance without the need to modify the Phase 1 basin, outlet control structure, nor overflow provisions. The volume control requirements for the project will capture a volume equal to 1" of water over the impervious area of the proposed improvements. This will be achieved by providing storage beneath the outlet pipe of the detention pond. The storage beneath the outlet pipe is to be drained down via a 4" underdrain located within the basin. Calculations for the ADS system following MWRD methodology is included in this report. All proposed impervious areas are considered in the requirements, including those that are not tributary to the east basin. The existing parking lot area will more than adequately function as trade off area for these considerations. Stormwater overflows will spill from both basins at differing elevations. The required overflow rates based on all tributary areas are included in this report, and appropriate provisions included in the design. All proposed site storm sewers will be sized to convey the 100-year flows to the stormwater management system. Storm sewer sizing calculations are included in this report and sewers are able to convey the 100-Year event to the basin without surcharging above grade. Additionally, all drainage and storm sewer infrastructure on the eastern portion of the improvements have overland overflow routes that are also tributary to the basin, meaning only western portions of the site fully rely on sewers for conveyance to the basin area. SUMMARY Stormwater management improvements are in accordance with MWRD requirements, and to the extent readily feasible, Village requirements. The team notes that Village Code requires that detention be provided for the entirety of the property when constructing a new building. This is in contradiction to MWRD requirements, where stormwater management improvements must be provided for all applicable Development Areas. At a minimum, this excludes substantial portions of the park district property where no work is proposed. There are minimal stormwater management facilities present in existing conditions, and the site in its current state provides stormwater benefits as it is primarily open green space. The improvements will result in approximately 10.2 Acres, or nearly 50% of the entire park district property, being tributary to and detained by stormwater management systems, compared to approximately 2.1 Acres, or 10%, in the existing conditions. Detention provisions will be sized for approximately 25% of the total property area, compared to approximately 5% in existing conditions. The Park District's underlying missing is to protect and preserve open space for recreation for the public, and the team believes that the design as proposed appropriately balances the needs of being good stormwater stewards while still preserving recreational opportunities. The project will have a sizable watershed benefit even while excluding portions of the property that will not be disturbed. Per preliminary calculations, providing detention for the entirety of the property would increase the required storage, and therefore footprint of stormwater facilities, by approximately 300%, placing an undue hardship on the park district that is counter productive to both Village and MPPD goals for the site. The team understands that a Standards Exception is required for this approach. Additional calculations and stormwater models were prepared upon Village request, analyzing the performance of the proposed east basin. Per the results of these models, which were provided under separate cover, the basin as designed can accommodate approximately the 25-year event before reaching the overflow elevation and approximately 10-year event before the basin fills to intended HWL. Given the significant watershed benefits and improvements to local sewer capacity/discharge rates, EEA believes that the currently provided storage adequately satisfy the intent of both MWRD and Village requirements.

("Client'), Soil Engineering and Testing Consultants, LLC (SET Consultants) has completed subsurface exploration and geotechnical engineering analyses for the proposed Mount Prospect Park District (MPPD) Lions Recreation Center located at 411 South Maple Street, in Mount Prospect, Illinois (referred to as "Site"). The professional engineering services were completed in accordance SET Consultants Proposal No. 2002 dated March 13, 2025 and approved by Client on the same day. This letter report consists of project description; scope of work; Site physical setting; subsurface exploration, laboratory testing procedures, and subgrade soil suitability and groundwater assessment results; and, geotechnical analyses and associated recommendations for proposed new building foundations, interior floor slabs and pavements. Attachments to this letter report include: • Figure 1 illustrates the geotechnical soil boring locations obtained for this letter report. • Table 1 summarizes the subsurface exploration and geotechnical findings with respect to an estimated design footing bottom subgrade elevation for proposed new buildings. • Geotechnical soil boring logs (Appendix A), and reference notes for boring logs (Appendix B) are included as separate letter report appendices. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 2 of 24 GEOTECHNICAL ENGINEERING ANALYSES SUMMARY & FOUNDATION RECOMMENDATIONS SET Consultants understands the development will entail construction of two Site buildings as follows: • Recreation Center ■ Two-story recreation center building with full -depth basement to be located within the north portion of the Site. ■ This building is expected to consist of exterior and interior load bearing precast walls, open web steel roof joist/beams and metal deck. • Pool Locker Room Building ■ One-story swimming pool locker room building with slab -on -grade construction to be located north of the existing swimming pool within the center portion of the Site. ■ This building is expected to have exterior and interior load bearing masonry walls supporting steel roof joists and metal deck. Pre -design services consisting of subsurface exploration and geotechnical engineering analyses is needed to assess subgrade soil suitability and groundwater occurrence for the proposed new buildings construction. A total of 19 geotechnical soil borings B-1 through B-15 and C-1 through C-4 were drilled along proposed new building exterior foundation walls targeting building corners where accessible and illustrated in Figure 1. Building design loads were not provided as of the date of this letter report. Subsurface Exploration Findings SET Consultants conducted subsurface exploration activities on Thursday, March 20, Friday, March 21, and Monday, March 24, 2025 and a total of 19 geotechnical soil borings (labeled B-1 through B-15 and C- 1 through C-4; Figure 1) were each drilled to 20 feet below existing surface grade with the exception of soil boring B-7 which was drilled to 40 feet below existing surface grade (Table 1; Appendix A). The geotechnical drilling was performed mainly within pavements, grass lawn areas, and athletic facilities situated near existing buildings throughout the Site (Figure 1). There were no Site access issues encountered for the drilling rigs and the personnel who operated this equipment. A summary of the findings from the subsurface exploration consists of the following: • Approximately 8 to 12 inches of maintained grass and topsoil was encountered at the ground surface at eleven borings. Approximately 3 to 5 inches of asphalt pavement underlain by 4 to 12 inches of aggregate basecourse was encountered at five of the boring locations (B-11, C-1 to C- 4). Approximately 5 to 6 inches of concrete underlain by 6 to 8 inches of aggregate basecourse was encountered at soil borings B-13 to B-15 located around the perimeter of the existing swimming pool. • At the fifteen structural borings (B-1 through B-15), interpreted, predominantly cohesive fill and possible fill soils extend between approximately 2-and-8.5 feet below ground surface (bgs) for the soil borings advanced for this subsurface exploration with the exception of B-14 were interpreted fill soils and unsuitable native soils extend down to approximately 11 feet bgs. These interpreted fill soils exhibited average soft to very stiff consistencies, and the overall water content (Wc) was calculated to range from 10.8% to 23.9%. Limited deposits of loose to medium dense sand and gravel fill were encountered in ten of the borings, and exhibited standard penetration test N values in the range from 4 to 22 blows per foot. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 3 of 24 • Native cohesive soils consisted of predominately silty clay and clayey silt, exhibited firm -very stiff overall average consistencies, and overall Wc was calculated to be in the range of 14.0% to 19.3%. • Within the predominant clay profile native oxidized granular soils were encountered in Borings B- 7, C-1 and C-4, consisted of predominantly poorly graded sand, exhibited very loose to medium dense relative density, and overall average W. was calculated to be 12.9% to 15.6%. • Native oxidized, brown dominant -colored soils transitioned to unoxidized cohesive soils with distinct gray coloration at an average depth of approximately 10 feet bgs or an average elevation of approximately 649.5 feet AMSL. • Native unoxidized cohesive soils consisted of predominantly silty clay, clay, clayey silt, and silt, and exhibited firm -very stiff overall average consistencies. • Groundwater was observed during the drilling operation at 13 of the 19 soil boring locations at a depth range of approximately 6-to-18.5 feet bgs with shallow groundwater (-7 feet or less bgs) occurring in soil borings B-9, B-12 and C-2. • In 13 of the boreholes, static groundwater levels were measured within open boreholes at drilling completion with HSAs removed and ranged in depth from 5-to-16 feet bgs. • After the HSAs were removed, overall average dry cave-in (DCI) measured at five (5) of the borings at depths of approximately 8 and 18.5 feet bgs (Appendix A). Overall average wet cave- in (WCI) was measured in 14 of the soil borings at depths ranging from approximately 12 to 17 feet bgs except at boring B-7 where WCI was measured at 33 feet bgs. • Bedrock was not encountered on -site from the soil borings completed for this subsurface exploration. Based on the project information provided to SET Consultants along with field and laboratory test data collected for this investigation, SET Consultants recommends the following for the proposed new buildings that will be slab -on -grade construction or full basement. • The proposed new buildings can be supported on a conventional shallow foundation system consisting of spread and/or continuous strip footings bearing on suitable, interpreted native, undisturbed cohesive soils with stiff -very stiff average consistencies encountered at depths ranging from approximately 3-to-8 feet or greater below the existing surface grade; or, bearing on new, properly compacted engineered fill consisting of either Site -derived or imported cohesive soils or imported engineered fill material such as 0.75-inch nominal diameter crushed aggregate with fines compacted to 95% of the maximum achievable dry density obtained in accordance with ASTM Specification D1557 Modified Proctor Method. Either option is considered feasible and appropriate to support the proposed new buildings. For spread and/or continuous strip footings, extending through existing fill soils and lower strength native cohesive soils, bearing at depths of at least 3.5 feet below final surface grade on either native, undisturbed cohesive soils with stiff - very stiff average consistencies, or new, properly compacted and moisture -conditioned engineered fill, we recommend a maximum net allowable soil bearing pressure of 3,000 pounds per square foot (psf) be used to proportion the footings for the proposed new buildings. • It is recommended that the freshly exposed subgrade soil at design footing bottom elevation of each building be evaluated and soil bearing strength field -verified under the observations of an experienced geotechnical engineer and/or soils technician. If field soil bearing strength readings verifying a 3,000 psf or greater net allowable soil bearing pressure can be attained for the native, Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 4 of 24 undisturbed soils then total and differential settlement risk of shallow footing foundations will be within acceptable limits. • The proposed new buildings are assumed to be interior slab -on -grade construction completed at - grade and full -depth removal of the existing fill soils and lower strength native cohesive soils encountered in the soil borings to depths of at least 3-to-8 feet or greater below existing surface grade and replacement with new engineered fill compacted to at least 95% of the material maximum achievable dry density per ASTM D1557 Modified Proctor Method carries the least risk of total and differential settlement of the floor slab. However, removal and replacement may be cost prohibitive. • As an alternative to removal and replacement, the exposed subgrade soil can be tested and evaluated with a combination of proofrolling, in -place moisture -density tests, and shallow probe test holes. It is the opinion of SET Consultants that testing and evaluation of existing fill soils under the observations of an experienced geotechnical engineer and/or soils technician can reduce the risk of total and differential movement of interior floor slabs to a reasonable level. However, if the Client is unwilling to accept some risk of total and differential settlement, the existing fill soils should be completely removed and replaced with new engineered fill to the depth encountered. PROJECT DESCRIPTION SET Consultants understands the development will entail construction of two Site buildings as follows: • Recreation Center ■ Two-story recreation center building with full -depth basement to be located within the north portion of the Site. ■ This building is expected to consist of exterior and interior load bearing precast walls, open web steel roof joist/beams and metal deck. • Pool Locker Room Building ■ One-story swimming pool locker room building with slab -on -grade construction to be located north of the existing swimming pool within the center portion of the Site. ■ This building is expected to have exterior and interior load bearing masonry walls supporting steel roof joists and metal deck.

The Site is presently bounded on the south by Lions Park Elementary School and residential dwellings followed by East Council Trail, on the west by South Maple Street followed by single-family residences, on the north by East Lincoln Street followed by multi -family apartment buildings, and on the east by park areas and South School Street. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 5 of 24 Site topography is mapped as relatively flat -lying with elevations ranging between approximately 658-and- 663 feet above mean sea level (AMSL) for the majority of the Site. There is a relatively lower elevation within the swimming pool area. Finished exterior grades at borings performed at other areas across the Site were in the range of elevation between approximately 656-and-661 feet AMSL. Mapped Soils According to soil mapping efforts published by the United States Department of Agriculture (USDA), the soils underlying the Site has been characterized as Orthents, clayey, undulating (USDA, 2024). The Orthents, clayey, undulating complex is associated with landforms consisting of outwash plains. The natural drainage is classified as "moderately well drained", and typical soil profile is silty clay from undisturbed ground surface to approximately 79 inches below surface grade. Additional soil properties of the Orthents, clayey, undulating complex include 1 to 6 percent slopes, very high runoff class, and negligible frequency to flooding and ponding. Surficial Geology Surficial geology mapping initially conducted by Bretz (1939) identified the soils across the site as characterized part of the Tinley Groundmoraine which is part of the Wadsworth Member of Wedron Formation (Lineback, 1979; Richmond and Fullerton, 1983). Lineback (1979) describe the Wedron Formation as gray, clayey and silty clayey till, relatively low in cobble and boulders. According to geologic mapping compiled by the Illinois State Geologic Survey (ISGS, 2015), the sediment or "drift deposit" thickness within Site vicinity is estimated to be at least 50 feet and may extend to 200 feet. Depth -to -groundwater within the Site vicinity was not identified from the limited literature search conducted for this investigation. SUBSURFACE EXPLORATION PROCEDURES This section discusses the geotechnical drilling activities completed Thursday, March 20 through Monday, March 24, 2025 and the laboratory testing procedures completed for soil samples collected as part of the field activities. Field drilling observations, soil sampling, and laboratory testing results were used for soil boring logs and findings summary table preparation. Client selected the locations of the 19 geotechnical soil borings advanced for this subsurface exploration. The Client requested private underground utility locating be conducted to "clear" drilling locations of potential underground utility conflicts before initiating the geotechnical drilling. Underground Utility Locating SET Consultants retained Earth Solutions, Inc. (ESI; St. Charles, Illinois) for geotechnical drilling. The Illinois One -Call Utility Dispatcher ("JULIE") was contacted by ESI for an underground utility locate at the Site to be conducted prior to the start of drilling operations. ESI coordinated the private underground utility locate prior to the start of drilling on March 20t" The soil boring locations were field -located and flagged prior to the start of drilling on Thursday, March 20t" before the start of the private underground utility locate. The private underground utility locate was conducted by a ESI field representative. The Existing Conditions Plan included buried utility alignments where known and was used as guidance during the non-destructive underground utility locating. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 6 of 24 The ESI field representative proceeded to field clear the 19 geotechnical soil borings (Figure 1). Geotechnical Soil Boring Drilling ESI mobilized two (2) drilling rigs with two -person crews for the geotechnical drilling operation. The soil borings were completed using Geoprobe Systems° 7822DT track -mounted drilling rigs equipped with HSAs to advance the boreholes. Representative soil samples were obtained continuously at 2.5 foot intervals to 10 feet bgs then sampled at 5-foot intervals to the maximum soil boring depths of 20 or 40 feet bgs (borings B-1 through B-15 and C-1 through C-4). Soil samples were collected by means of conventional split -spoon (SS) sampling procedures. In this procedure, a 2-inch outside diameter (O.D.) SS sampler is driven into the soil a distance of 18 inches by a 140-pound hammer weight falling 30 inches. The number of blows required to drive the SS sampler through a 12-inch interval, after initial setting of 6 inches is termed the Standard Penetration Test (SPT) or N-value and is indicated for each sample on the soil boring logs (Appendix A). The N-value can be used as a qualitative indication of the in -place relative consistency of cohesive soils and an indicator for the relative density of granular soils. These indicators are qualitative since many factors can significantly affect the standard penetration resistance value and prevent a direct correlation between drilling crews, rigs and procedures, and hammer -rod -sampler assemblies. The drilling rigs were equipped with an automatic trip hammer to drive the SS sampler. Consideration of the effect of the automatic hammer efficiency was included in the interpretation of subsurface information for the analyses prepared for this letter report. A SET Consultants Professional Geologist and a Professional Engineer recorded field logs of the soils encountered during the soil boring operation. After recovery, each geotechnical soil sample was removed from the sampler, visually classified, measured, and photographed. These field logs were later used to prepare the final geotechnical soil boring logs (Appendix A). Soil samples obtained from the drilling operation were identified by boring numbers and sampling depths, sealed in glass jars in the field, and delivered to the laboratory for further visual examination and laboratory testing. The unconfined compressive strength (Qp) of cohesive soils was measured using a spring -loaded, hand-held penetrometer once the SS sample was retrieved from each borehole during the drilling operation. In the hand penetrometer test, the Qp of a soil sample is estimated, to a maximum of 4.5 tons per square foot (tsf) by measuring the resistance of a soil sample to penetration of a small spring -loaded cylinder. After completion of the drilling operations, the boreholes were backfilled with auger soil cuttings to the existing ground surface. Borings performed within pavement areas were patched with cold asphalt to restore to existing surface grade. Laboratory Testing The laboratory testing program included natural moisture content determinations and visual classifications. Natural moisture or W, for each subgrade soil sample was determined using ASTM Standard D2216 for representative portions of the sample. During the laboratory testing procedure, the field classification for each soil sample was verified in accordance with the Unified Soil Classification Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 7 of 24 System (USCS) using ASTM Standards D2487 and D2488. Each subgrade soil sample was classified on the basis of texture and plasticity in accordance with the USCS. The soil boring logs detail the soil sample intervals that were obtained, physically described, and visually classified using the USCS. The group symbols for each soil type are indicated along with the soil descriptions on the geotechnical boring logs (Appendix A). An explanation of the USCS symbols and boring log reference notes are included in Appendix B. Please Note: Interpreted fill soils (i.e., those soils revealing physical attributes of having been reworked, disturbed, and/or of non-native origin) were not assigned a USCS group symbol and designated as "Fill" or "Possible Fill". SET Consultants grouped the various soil types into lithostratigraphic zones that were generally consistent across the boring logs for this investigation. Lithologic color variation and patterns designating the interfaces between earthen materials on the soil boring logs (Appendix A) are approximate, and based on in -situ conditions these transitions may be more gradual. Please Note: The soil samples will be retained in the laboratory for a period of 30 days, after this time the soil samples will be discarded unless other instructions are received as to their disposal. EXPLORATION RESULTS This section discusses observations from the drilling activities completed March 20, March 21 and March 24, 2025. Site Physical Description The geotechnical drilling was performed mainly within open, maintained grass lawn areas or paved areas situated either near existing buildings or exterior asphalt pavements (Figure 1). There were no Site access issues encountered for the drilling rigs and the personnel who operated this equipment that prevented completing the field scope of work. The relatively flat -lying Site topography with approximately 5 feet vertical relief allowed for drilling rig setups to be positioned on level surface grade. There were no mounds or unusual topography observed, and there was no observed standing water or areas of distressed vegetation. Subsurface Exploration Findings SET Consultants conducted subsurface exploration activities on Thursday, March 20, Friday, March 21, and Monday, March 24, 2025 and a total of 19 geotechnical soil borings (labeled B-1 through B-15 and C- 1 through C-4; Figure 1) were each drilled to 20 feet below existing surface grade with the exception of soil boring B-7 which was drilled to 40 feet below existing surface grade (Table 1; Appendix A). The geotechnical drilling was performed mainly within pavements, grass lawn areas, and athletic facilities situated near existing buildings throughout the Site (Figure 1). There were no Site access issues encountered for the drilling rigs and the personnel who operated this equipment. A summary of the findings from the subsurface exploration consists of the following: • Approximately 8 to 12 inches of maintained grass and topsoil was encountered at the ground surface at eleven borings. Approximately 3 to 5 inches of asphalt pavement underlain by 4 to 12 inches of aggregate basecourse was encountered at five of the boring locations (B-11, C-1 to C- 4). Approximately 5 to 6 inches of concrete underlain by 6 to 8 inches of aggregate basecourse Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 8 of 24 was encountered at soil borings B-13 to B-15 located around the perimeter of the existing swimming pool. • At the fifteen structural borings (B-1 through B-15), interpreted, predominantly cohesive fill and possible fill soils extend between approximately 2-and-8.5 feet bgs for the soil borings advanced for this subsurface exploration with the exception of B-14 were interpreted fill soils and unsuitable native soils extend down to approximately 11 feet bgs. These interpreted fill soils exhibited average soft to very stiff consistencies, and the overall W, was calculated to range from 10.8% to 23.9%. Limited deposits of loose to medium dense sand and gravel fill were encountered in ten of the borings, and exhibited standard penetration test N values in the range from 4 to 22 blows per foot. • Native cohesive soils consisted of predominately silty clay and clayey silt, exhibited firm -very stiff overall average consistencies, and overall Wc was calculated to be in the range of 14.0% to 19.3%. • Within the predominant clay profile native oxidized granular soils were encountered in Borings B- 7, C-1 and CA consisted of predominantly poorly graded sand, exhibited very loose to medium dense relative density, and overall average W, was calculated to be 12.9% to 15.6%. • Native oxidized, brown dominant -colored soils transitioned to unoxidized cohesive soils with distinct gray coloration at an average depth of approximately 10 feet bgs or an average elevation of approximately 649.5 feet AMSL. • Native unoxidized cohesive soils consisted of predominantly silty clay, clay, clayey silt, and silt, and exhibited firm -very stiff overall average consistencies. • Groundwater was observed during the drilling operation at 13 of the 19 soil boring locations at a depth range of approximately 6-to-18.5 feet bgs with shallow groundwater (-7 feet or less bgs) occurring in soil borings B-9, B-12 and C-2. • In 13 of the boreholes, static groundwater levels were measured within open boreholes at drilling completion with HSAs removed and ranged in depth from 5-to-16 feet bgs. • After the HSAs were removed, overall average DCI measured at five (5) of the borings at depths of approximately 8 and 18.5 feet bgs (Appendix A). Overall average WCI was measured in 14 of the soil borings at depths ranging from approximately 12 to 17 feet bgs except at boring B-7 where WCI was measured at 33 feet bgs. • Bedrock was not encountered on -site from the soil borings completed for this subsurface exploration. Groundwater Observations Observations for groundwater were made during sampling and upon completion of the drilling operation at each soil boring location. In auger drilling operations, water is not introduced into the boreholes, and the groundwater position can often be obtained by observing water flowing into or out of the boreholes. Furthermore, visual observation of the soil samples retrieved during the drilling exploration can often be used in evaluating the groundwater conditions. Groundwater was observed during the drilling operation at 13 of the 19 soil boring locations at a depth range of approximately 6-to-18.5 feet bgs with shallow groundwater (-7 feet or less bgs) occurring in soil borings B-9, B-12 and C-2. In 13 of the boreholes, static groundwater levels were measured within open boreholes at drilling completion with HSAs removed and ranged in depth from 5-to-16 feet bgs (Appendix A; Table 1). Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 9 of 24 After the HSAs were removed, overall average DCI measured at five (5) of the borings at depths of approximately 8 and 18.5 feet bgs (Appendix A). Overall average WCI was measured in 14 of the soil borings at depths ranging from approximately 12 to 17 feet bgs except at boring B-7 where WCI was measured at 33 feet bgs. Glacial sediments common to the Site vicinity frequently oxidize from gray -to -brown at the interface between where the soil has remained fully saturated and overlying partially or intermittently saturated and vadose zones. The interpreted long-term groundwater level can be interpreted to be near this zone of color change. Based on the results of this exploration, a long-term groundwater level was observed for each soil boring and interpreted to range from approximately 8 feet to 12 feet bgs. The average elevation range for the interpreted long-term groundwater level is approximately 649.5 feet AMSL. It should be noted that the groundwater level can vary based on precipitation, evaporation, surface runoff, and other factors not immediately apparent at the time of this exploration. Surface water runoff may be a factor during general construction, and steps should be taken during construction to control surface water runoff and to remove water that may accumulate in the planned excavations as well as floor slab areas. Seismic Zone Based on the 2015 International Building Code, Chapter 16 Structural Design, Section 1613.3.2 - Site Class Definitions, the Site soils can be characterized as Site Class D. Site Class D is described as "Stiff soil' for the top 100 feet (i.e., the ground surface to 100 feet bgs interval) with an average shear strength in the range of 1,000 to 2,000 psf and Standard Penetration Test blowcounts in the range of 15 to 50 blows per foot for this interval (ASCE, 2010). Soil borings extended to a maximum depth of 25 feet bgs for this subsurface exploration. Based on our experience with similar soils in Site vicinity, the available geologic literature that identifies overburden or unconsolidated sediment thickness within Site vicinity is at least 50 feet bgs and may extend to 200 feet bgs (ISGS, 2015), and following the direction of ASCE (2010) when there are no borings to 100 feet bgs, the Site soils meet criteria for Site Class D. ANALYSES AND RECOMMENDATIONS The following recommendations have been developed on the basis of the previously described project characteristics and objectives and subsurface conditions encountered during this field investigation. If there are any changes to the project characteristics, objectives, or if different subsurface conditions are encountered during construction then these changes need to be brought to the attention of SET Consultants so that the recommendations of this letter report can be reviewed. Analyses and Recommendations Overview Based on the project information provided to SET Consultants along with field and laboratory test data collected for this investigation, SET Consultants recommends the following for the proposed new buildings that will be slab -on -grade construction or full basement. • The proposed new buildings can be supported on a conventional shallow foundation system consisting of spread and/or continuous strip footings bearing on suitable, interpreted native, undisturbed cohesive soils with stiff -very stiff average consistencies encountered at depths ranging from approximately 3-to-8 feet or greater below the existing surface grade; or, bearing on new, properly compacted engineered fill consisting of either Site -derived or imported cohesive Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 10 of 24 soils or imported engineered fill material such as 0.75-inch nominal diameter crushed aggregate with fines compacted to 95% of the maximum achievable dry density obtained in accordance with ASTM Specification D1557 Modified Proctor Method. Either option is considered feasible and appropriate to support the proposed new buildings. For spread and/or continuous strip footings, extending through existing fill soils and lower strength native cohesive soils, bearing at depths of at least 3.5 feet below final surface grade on either native, undisturbed cohesive soils with stiff - very stiff average consistencies, or new, properly compacted and moisture -conditioned engineered fill, we recommend a maximum net allowable soil bearing pressure of 3,000 psf be used to proportion the footings for the proposed new buildings. • It is recommended that the freshly exposed subgrade soil at design footing bottom elevation of each building be evaluated and soil bearing strength field -verified under the observations of an experienced geotechnical engineer and/or soils technician. If field soil bearing strength readings verifying a 3,000 psf or greater net allowable soil bearing pressure can be attained for the native, undisturbed soils then total and differential settlement risk of shallow footing foundations will be within acceptable limits. • The proposed new buildings are assumed to be interior slab -on -grade construction completed at - grade and full -depth removal of the existing fill soils and lower strength native cohesive soils encountered in the soil borings to depths of at least 3-to-8 feet or greater below existing surface grade and replacement with new engineered fill compacted to at least 95% of the material maximum achievable dry density per ASTM D1557 Modified Proctor Method carries the least risk of total and differential settlement of the floor slab. However, removal and replacement may be cost prohibitive. • As an alternative to removal and replacement, the exposed subgrade soil can be tested and evaluated with a combination of nroofrollina. in -place moisture-densitv tests. and shallow probe test holes. It is the opinion of SET Consultants that testing and evaluation of existing fill soils under the observations of an experienced geotechnical engineer and/or soils technician can reduce the risk of total and differential movement of interior floor slabs to a reasonable level. However, if the Client is unwilling to accept some risk of total and differential settlement, the existing fill soils should be completely removed and replaced with new engineered fill to the depth encountered. Finished -floor elevations (FFEs) were not provided by Client as of this letter report date, and an estimated site wide FFE of 654 feet AMSL was used for purposes of discussion. Table 1 summarizes the geotechnical findings for structural soil borings B-1 through B-15 to include approximate depth to native soils suitable for a net allowable bearing pressure of 3,000 psf, geotechnical findings for civil soil borings C-1 through C-4 to include an estimated design subgrade elevation of 1 foot below existing ground surface elevation for proposed exterior pavement rehabilitation, and the field and laboratory geotechnical findings at the estimated design subgrade elevations for shallow foundation system and pavement rehabilitation construction. The majority of subgrade soils encountered at the frost -depth elevation (minimum 3.5 feet bgs) for at - grade construction are interpreted cohesive native soils that exhibit firm -very stiff average consistencies with average We calculated to be approximately 18%. Table 1 presents the findings for soil samples collected at or below the estimated design subgrade elevation to be suitable at all but two of the structural soil boring locations to proportion shallow foundation footings. Unsuitable silty clay soils where Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 11 of 24 encountered at eight soil boring locations at the estimated design footing bottom elevation based on estimated observed fill soils down to 5.5 to 8 feet bgs or greater. Note: Soil boring B-14 drilled east of the swimming pool (Figure 1; Table 1) encountered unsuitable silty clay soils consisting of soft to firm, moist, mottled fill soils with trace organics, and soft to stiff consistency native cohesive soils down to approximately 11 feet bgs. Based on these geotechnical findings for the proposed new building foundations, overexcavation below the design subgrade elevation as presented in this letter report is anticipated for at -grade construction to range from 0 to 4 feet bgs or greater with an average overexcavation of 2 feet expected. The following items are addressed in the remainder of the ANALYSES AND RECOMMENDATIONS section: • Subgrade Preparation; • Engineered Fill; • Footing Foundations; • Lateral Earth Pressures; • Interior Floor Slab Design; • Pavement Design Recommendations; and, • General Construction Considerations. Subgrade Preparation This section discusses subgrade preparation activities to include initial Site preparation, underground utilities, proofrolling, and compaction. Based on historical information reviewed for this letter report, the present-day Site configuration appears to have remained unchanged since the early 1980's or earlier. There has been no project -specific information provided such as the building design loads as of the date of this letter report. Initial Site Preparation — Initial subgrade preparation should consist of complete removal of existing exterior flatwork, vegetation, and any other soft or unsuitable/deleterious materials within the location of the proposed new building footprints. Stripping limits should extend to a minimum of 10 feet beyond the limit of the new building footprints and a minimum of 5 feet beyond the edge of exterior pavements and flatwork. Unsuitable materials, such as topsoil/buried topsoil or organic soils, should either be stockpiled for later use in landscaping fills or placed in approved disposal areas either on -site or off -site. Below grade obstructions that may be exposed and encountered during initial Site preparation should be completely removed where these buried structures will conflict with new construction. Soils exposed in the excavations where buried structures are encountered should be observed and evaluated by an experienced geotechnical engineer or soils technician. The completed excavations should be backfilled with properly placed and compacted fill as recommended in this letter report. Improper placement and compaction of fill materials during removal of below grade obstructions and other structures could lead to inconsistent subgrade performance resulting in foundation, floor slab, and pavement distress and settlement. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 12 of 24 We recommend that the project geotechnical engineer or a qualified and authorized representative be on -site to monitor Site soil stripping and preparation operations, observe and document that unsuitable soils have been satisfactorily removed. Underground Utilities — Prior to construction, all utilities in the proposed construction area need to be positively identified and marked. If existing utilities are positively identified within the proposed construction area then these existing utilities should be abandoned and/or relocated, and structures and backfill materials associated with the existing utilities should be removed from the proposed new building footprint areas unless the existing utilities are planned to remain in service for the new building structures. Those utilities that can be relocated should be relocated to the extent practical and backfilled with compacted/densified engineered fill. Abandoned utilities should be removed or grouted full with lean concrete. Excavations resulting from removal/demolition of existing utilities and other structures should be completely filled with engineered fill. Active utilities to remain in the construction area should be exposed and protected during construction to reduce the potential for damage or interruption of service. Where existing utilities will remain under any structure, we recommend that the utility backfill be removed and replaced with controlled fill. Proofrolling - After removal of unsuitable/deleterious materials and stripping to the desired grade, and prior to fill placement, we recommend the stripped/exposed subgrades be observed by an experienced geotechnical engineer or qualified and authorized representative at the time of construction to aid in identifying localized soft/loose or unsuitable materials that should be removed. Proofrolling within the proposed new building pad areas using a loaded, minimum 3- axle dump truck having a net weight of at least 10 tons may be used at this time to aid in identifying localized soft or unsuitable material which should be removed. Any soft or unsuitable materials encountered during proofrolling should be compacted in place or removed and replaced with an approved backfill compacted to the criteria specified for the project and discussed in the following section. Prior to proofrolling, floor slab areas that will receive less than 1 foot of new fill, should be scarified to a depth of about 9 inches, moisture conditioned, and recompacted as recommended below. We recommend that the project geotechnical engineer or a qualified and authorized representative be on -site to observe the proofrolling operations. Compaction — Based on what is known about the Site development history, it is possible that there has been an appreciable amount of fill placement and/or compaction performed on -site. If there are records of soil stabilization or other modifications to the soil profile then this pertinent information should be provided to SET Consultants for review. However, if records are not available and the existing fill soils appear to have some measure of control of moisture content and density then it might be feasible for these existing fill soils to support interior floor slabs and new fill material. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 13 of 24 Feasibility of the new construction may need to be considered so it cannot be ruled out that some existing fill soils may remain in place for the at -grade interior floor slabs. If the Client is willing to accept some risk of total and differential settlement and associated long term maintenance, the existing fill soils or lower strength native cohesive soils similar to those encountered in the soil borings to depths of at least 3 to 8 feet or greater below the existing surface grade may remain in - place below interior floor slab areas but the subgrade must pass a proofroll under the observation of a SET Consultants geotechnical engineer or soils technician. However, if the Client is unwilling to accept the risk then the existing fill soils should be completely removed and replaced with new engineered fill. During final preparation of subgrades, a smooth drum roller is often used to provide a flat surface and provide for better drainage to reduce the negative impact of rain events. Due to the relative sensitivity of silty clay soils, we recommend that these materials be static rolled (no vibrations) to reduce the potential for subgrade soil disturbance. We also recommend crowning the subgrade to provide positive drainage off the proposed new building pad areas. Engineered Fill Where new fill material is required for backfill or to otherwise reach the design subgrade elevation beneath slab -on -grade, we recommend that engineered fill be used. Any soil placed as engineered fill should be an approved material, free of organic matter or debris, be a non -frost susceptible soil, and have a liquid limit and plasticity index less than 40 and 15, respectively. The project geotechnical engineer should be consulted to determine the suitability of off-site/on-site materials for use as engineered fill prior to use or placement. Placement & Testing — Engineered fill should be placed in lifts not exceeding 9 inches in loose thickness, moisture conditioned to within 2% of the optimum moisture content and compacted to at least 95% of the maximum achievable dry density obtained in accordance with ASTM Specification D1557 Modified Proctor Method. Engineered fill placed below footing base elevations should be compacted to at least 95% of the maximum achievable dry density of the material (ASTM D1557). Engineered fill placed to support foundations should extend 1 foot beyond the outside edges of the footings and from that point outward laterally 1 foot for every 2 feet of fill thickness below the footings. Laboratory proctor tests should be performed on fill materials to determine the maximum achievable dry density and optimum moisture content. We recommend suitable silty clay soils be used to raise the grade or to backfill overexcavation within the proposed new building areas and should be compacted with sheepsfoot roller. Granular engineered fill should be compacted with a smooth drum roller or adequate heavy vibratory plate. Moisture control during earthwork operations including the use of disking or appropriate drying equipment and techniques should be expected. In -place density tests should be performed with a minimum of 1 test per 2,000 square feet of fill area for each lift of fill placed. We recommend that the placement of engineered fill be monitored full-time by a SET Consultants representative and in -place density tests should be performed to verify the adequacy of the compaction for each lift of fill placed. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 14 of 24 Footing Foundations Based on the project information along with field and laboratory test data collected for this investigation, SET Consultants recommends the proposed new buildings can be supported on a conventional shallow foundation system consisting of spread and/or continuous strip footings bearing on suitable, interpreted native, undisturbed cohesive soils with stiff -very stiff average consistencies encountered at depths ranging from approximately 3-to-8 feet or greater below the existing surface grade; or, bearing on new, Properly compacted engineered fill consisting of either Site -derived or imported cohesive soils or imported engineered fill material such as 0.75-inch nominal diameter crushed aggregate with fines compacted to 95% of the maximum achievable dry density obtained in accordance with ASTM Specification D1557 Modified Proctor Method. Either option is considered feasible and appropriate to support the proposed new buildings. For spread and/or continuous strip footings, extending through existing fill soils and lower strength native cohesive soils, bearing at depths of at least 3.5 feet below final surface grade on either native, undisturbed cohesive soils with stiff -very stiff average consistencies, or new, properly compacted and moisture -conditioned engineered fill, we recommend a maximum net allowable soil bearing pressure of 3,000 pounds per square foot (psf) be used to proportion the footings for the proposed new buildings. It is recommended that the freshly exposed subgrade soil at design footing bottom elevation of each building be evaluated and soil bearing strength field -verified under the observations of an experienced geotechnical engineer and/or soils technician. If field soil bearing strength readings verifying a 3,000 psf or greater net allowable soil bearing pressure can be attained for the native, undisturbed soils then total and differential settlement risk of shallow footing foundations will be within acceptable limits. To reduce the potential for foundation bearing failure and excessive settlement due to local shear or "punching" action, we recommend that continuous strip footings have a minimum width of 24 inches. If there are column footings in the design of the proposed new buildings then we recommend a minimum lateral dimension of 30 inches be used for the foundation design. In addition, footings should be placed at a depth to provide adequate frost cover protection. We recommend the footings be placed at a minimum depth of at least 3.5 feet below finished surface grade. Interior footings in heated areas can be placed at a minimum of 2 feet below grade provided that suitable soils are encountered and that the foundations will not be subjected to freezing weather either during or after construction, though these foundations must also extend to suitable, natural soils. We recommend that the excavation of the proposed new building foundations be monitored on a full-time basis by a SET Consultants geotechnical engineer or materials technician to verify that the exposed subgrade soils bearing strength will be suitable for the proposed new buildings and is consistent with the soil boring log information obtained during the geotechnical exploration. The contractor should be prepared to overexcavate and extend the footings to soils of adequate bearing strength. As an alternative, after overexcavation and removal of weaker/lower strength soils or other unsuitable soils, the foundation subgrade can be raised using compacted engineered fill to a minimum frost depth of 3.5 feet below final exterior surface grade. The zone of the engineered fill placed below the foundation should extend 1 foot beyond the outside edges of the footings and from that point, outward laterally 1 foot for every 2 feet of fill thickness below the footing. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 15 of 24 Settlement of the conventional shallow foundation, designed in accordance with our recommendations presented in this letter report, is expected to be within tolerable limits for the proposed new building and parking lots. For footings extending through existing fill soils, and placed on native, undisturbed, either cohesive soils with stiff -very stiff average consistencies or granular soils with medium dense average density or lean concrete backfill extending down to suitable natural soils, and assuming the construction recommendations discussed above are followed, we estimate that the total and differential settlement should be on the order of 1.0 and 0.5 inches, respectively. These settlement values are based on our engineering experience with the soil, the anticipated structural loading, and are to be used to guide the structural engineer with the design. Rammed/Vibrocompacted Aggregate Piers Existing fill soils were encountered in the borings at depths between approximately 3.5 and 8.5 feet or greater below the current ground surface. Complete removal and replacement discussed above may not be economical due to high construction cost. As an alternative, for ground improvement techniques and construction of conventional shallow foundations, the use of compacted/rammed aggregate piers, similar to Geopier® rammed aggregate piers and Vibro Piers can be considered for support of foundations for the new buildings. It is our opinion that foundations supported on compacted/rammed aggregate piers or Vibro Piers as discussed above will likely permit proportioning foundations for a net allowable soil bearing capacity of 3,000 psf, though this must be verified by the rammed aggregate piers or Vibro Piers installer. The compacted/rammed aggregate piers can be used to reinforce the existing soils beneath spread and wall footings, load bearing walls and floor slabs. The compacted/rammed aggregate piers are constructed by drilling approximately 2'/2 feet in diameter boreholes extending through the layers of unsuitable soils and compacted/ramming thin lifts of new aggregate fill materials within the boreholes to create dense aggregate piers. The compacted/rammed aggregate piers should be constructed through layers of exiting fill soils and anticipated to extend to natural, stiff to hard silty clay, clay, silt and clayey silt at depths of about 3.5 to 8.5 feet or greater below existing_ grade. Temporary casing will likely be needed during construction of the aggregate piers through the existing fill soils. Aggregate piers should be constructed on a grid pattern using well -graded granular soils tamped in thin lifts. We anticipate spacing of compacted/rammed aggregate piers should be in the range of 5 to 10 feet on center. Our experience suggests that aggregate pier manufacturers will interpret the available subsurface information and can provide appropriate foundation design including allowable bearing pressure and anticipated settlement. The compacted/rammed aggregate piers can also be used to support floor slabs. For buildings with compacted/rammed aggregate piers, similar to Geopier® rammed aggregate piers and Vibro Piers, floor slabs and the required granular base course can be constructed on top of aggregate piers. Prior to the construction of floor slabs, the subgrade preparation should consist of densifying the exposed design subgrade surface to the extent practical prior to placement of granular base course and concrete. We recommend that the excavation of building foundations be monitored on a full-time basis by a SET geotechnical engineer or his representative to verify the exposed soils and the soil bearing capacity will be suitable for the proposed building and is consistent with the boring log information obtained during the geotechnical exploration. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 16 of 24 For footings bearing above soil improved using rammed aggregate piers properly designed and installed, maximum total settlement is expected to be in the range of 1 inch or less based on consolidation of the soils under structural loading. These settlement values are based on our engineering experience with the soil and the anticipated structural loading, and are to guide the structural engineer with his design. Lateral Earth Pressures Permanent below grade walls should be designed to withstand lateral earth pressures and surcharge loads. The lateral earth pressures exerted on the walls will be a function of the stiffness and the rotation of the walls. The rotation of the wall controls the degree to which the internal strength of the soil is mobilized. If rotation or deflection of the walls will be less than that required to mobilize the active earth pressure condition due to stiffness, bracing or other mechanism (as is typical with basement walls), the "at -rest" earth pressure condition should be evaluated. For the at -rest earth pressure condition, below grade walls can be designed for a linearly increasing lateral earth pressure of 65 psf per vertical foot of wall above the long-term groundwater level and 100 psf/ft below the long-term groundwater level. If the rotation or deflection of the walls will be greater than required to mobilize the active earth pressure condition due to stiffness, bracing or other mechanism (as is common for retaining walls), the "active" earth pressure condition should be evaluated. For the active earth pressure conditions, below grade walls can be designed for a linearly increasing lateral earth pressure of 45 psf per vertical foot of wall above the long-term ground water level and 85 psf/ft below the long-term groundwater level. These at -rest and active lateral earth pressures assume that granular materials are used for wall backfill. The wall design should also account for any surcharge loads within a 45 degree slope from the base of the wall. For the at -rest earth pressure condition, a lateral earth pressure coefficient of 0.5 should be applied to surcharge loads. We recommend the basement walls be provided with a perimeter drainage system, as described above, to reduce the potential for excess hydrostatic pressures to be exerted on the walls. This system may consist of perforated or porous wall, closed joint drain tiles located around the perimeter of the walls, slightly below the lower slab level. We recommend waterproofing and damp proofing of walls be considered for basement walls. Based on the groundwater level information obtained from the boring, damp proofing of the basement walls should be adequate. Waterproofing/damp proofing and waterstops measures should be installed in accordance with local building code requirements. The space between the outside of the walls and the excavation should be backfilled with a granular fill. The ground surface adjacent to the below grade walls should be kept properly graded to prevent ponding of water adjacent to the below grade walls. To achieve a desirable balance between minimizing excessive pressures against the below grade walls and reducing the settlement of the wall backfill, we recommend that the wall granular backfill be compacted to at least 90% of the maximum dry density obtained in accordance with ASTM Specification D 1557, Modified Proctor Method. Where the fill materials will be supporting sidewalks or pavements, the upper 1 foot should be compacted to 95% of the maximum dry density referenced above. It has been our experience that compaction of backfill around building structures is typically poor in both materials and workmanship resulting in substantial settlements adjacent to the structure. These settlements are most evident on stoops, porches and driveways. Therefore, we recommend all backfilling be monitored by a SET representative to reduce the potential for settlement related problems. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 17 of 24 Backfill materials should consist of inorganic materials, free of debris, be free draining, and containing no frost susceptible soil. The fill placed adjacent to the below grade walls should not be overcompacted. Heavy earthwork equipment should maintain a minimum horizontal distance away from the below grade walls of 1 foot per foot of vertical wall height. Lighter compaction equipment should be used close to the below grade walls. Where light (e.g., hand) compaction equipment is employed, the maximum lift thickness should be reduced to 6 inches. Depending upon the method of excavation (i.e. sheeting), it may be difficult to install a perimeter drain system. Use of geosynthetic wall drain, such as Enka drain, or similar material may be needed to facilitate drainage. If friction at the base of the wall is insufficient and additional resistance to sliding is required, the provision for a shear key at the bottom of the wall may be considered. A key develops additional lateral resistance using passive earth pressures. To develop passive earth pressures, the key should be located at depths greater than the depth of frost penetration (3'/z feet below lowest adjacent finished grade). Parameters for the design of footings for lateral resistance are provided in Passive Earth Pressure, provided below. Passive Earth Pressure* Soil Type Kp Equivalent Fluid Pressure (psf) Granular Soils Sand/Silt 3.0 360 Cohesive Soils (Clay) 2.2 264 * To be used more than 3.5 feet below final grade. SET anticipates the primary component of lateral resistance will be developed by friction along the horizontal interface between the footing concrete and underlying soil. The friction coefficients (f) for cohesive and granular materials are provided in Coefficients of Friction for Spread Footings. Coefficients of Friction for Spread Footings* Concrete Over Cohesive Material (Clay/Silt) If = 0.35 Concrete Over Granular Material (Sand) If = 0.55 *These Values do Not Reflect a Factor of Safety It is important to note that since sliding resistance is mobilized with movement, it would follow that passive failure would have likely occurred. Therefore, the design of the wall should account for resistance to reflect either sliding resistance or passive resistance. The use of both resistance mechanisms in the design should not be performed. Interior Floor Slab Design The proposed new buildings are assumed to be interior slab -on -grade construction completed at -grade and full -depth removal of the existing fill soils and lower strength native cohesive soils encountered in the soil borings to depths of at least 3-to-8 feet or greater below existing surface grade and replacement with new engineered fill compacted to at least 95% of the material maximum achievable dry density per ASTM D1557 Modified Proctor Method carries the least risk of total and differential settlement of the floor slab. However, removal and replacement may be cost prohibitive. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 18 of 24 As an alternative to removal and replacement, the exposed subgrade soil can be tested and evaluated with a combination of proofrolling, in -place moisture -density tests, and shallow probe test holes. It is the opinion of SET Consultants that testing and evaluation of existing fill soils under the observations of an experienced geotechnical engineer and/or soils technician can reduce the risk of total and differential movement of interior floor slabs to a reasonable level. However, if the Client is unwilling to accept some risk of total and differential settlement, the existing fill soils should be completely removed and replaced with new engineered fill to the depth encountered. We recommend that non-structural or non -load bearing floor slabs be underlain by a minimum of 6 inches of imported granular fill material such as 0.75-inch nominal diameter crushed aggregate with fines. The imported granular fill material should be placed in lifts not exceeding 9 inches in loose thickness and compacted to at least 95% of the material maximum achievable dry density in accordance with ASTM D1557. Prior to placing the granular fill material, the floor subgrade soil should be properly compacted, proofrolled, and free of standing water, mud, and frozen soil. For design of Portland Cement Concrete (PCC) slabs -on -grade, a modulus of subgrade reaction (k) of 100 pounds per cubic inch (pci) can be used for slabs constructed on subgrade prepared as discussed herein. There may be sections of the at -grade floor slab that will not extend to suitable, native, undisturbed soils but will be supported on existing fill soils. Furthermore, it is assumed that the existing floor slab subgrade has performed satisfactorily during the proofroll discussed in the Subgrade Preparation subsection even though there are existing fill soils and lower strength native cohesive soils encountered to depths of at least 3 feet or greater below existing surface grade or lower in elevation. Provided that the floor slab subgrade passes a proofroll, the risk of excessive settlement is low. However, if the floor slab subgrade does not pass the proofroll then some overexcavation and placement of controlled backfill or lean concrete will be required. Please Note: Engineered fill material used as controlled backfill such as 0.75-inch nominal diameter crushed aggregate with fines needs to be moisture -conditioned to within 2% of the optimum moisture content and compacted to at least 95% of the material maximum achievable dry density obtained in accordance with ASTM D1557. A properly designed and constructed capillary break layer can often mitigate the need for a moisture retarder and can assist in more uniform curing of concrete. If a vapor retarder is considered to provide additional moisture protection, special attention should be given to the surface curing of the slabs to reduce uneven drying of the slabs and associated cracking and/or slab curling. The use of a blotter or cushion layer above the vapor retarder can also be considered for project specific reasons. Please refer to ACI 302.1 R96 Guide for Concrete Floor and Slab Construction and ASTM El 643 Standard Practice for Installation of Water Vapor Retarders Used in Contact with Earth or Granular Fill Under Concrete Slabs for additional guidance on this issue. We recommend that the floor slab be isolated from the foundation footings so differential settlement of the structure will not induce shear stresses on the floor slab. Also, in order to reduce the crack width of any shrinkage cracks that may develop near the surface of the slab, we recommend steel mesh reinforcement as a minimum be included in the design of the floor slab. Temperature and shrinkage reinforcements in slabs -on -grade should be positioned in the upper third of the slab thickness. The Wire Reinforcement Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 19 of 24 Institute recommends the steel mesh reinforcement be placed 2 inches below the slab surface or in the upper one-third of slab thickness, whichever is closer to the surface. Adequate construction joints, contraction joints, and isolation joints should also be provided in the slab to reduce the impacts of cracking and shrinkage. Please refer to ACI 302.1 R96 Guide for Concrete Floor and Slab Construction for additional information regarding concrete slab joint design. Underslab Drainage It would also be prudent to install an underslab drain system beneath the basement floor slab to collect water that infiltrates from the soils adjacent to basement walls as well as from the ground surface. The drain system could consist of a 6-inch thick layer of free draining base underlain by drains composed of perforated pipe placed in a trench that is backfilled with free -draining granular material. The trenches should extend 12 inches below the floor slab subgrade and should be spaced at 50 feet center -to -center. The drain systems should be sloped to provide positive gravity drainage to a frost -free outlet or sump equipped for automated pumping. Pumps should be sized and selected to adequately handle potential flows that may be encountered at the desired basement depths. Redundant pumps with battery backup power should be considered, to reduce the risk of basement seepage in the event of pump and/or power failure. Periodic maintenance of the drainage systems is necessary so that they do not become plugged and inoperative. Pavements For the design and construction of exterior pavements, we recommend that topsoil, old pavement be removed before construction of new pavements and that new pavements will be supported by stable and approved subgrades consisting of silty clay, or on new, properly compacted engineered fill. It is assumed that the existing pavement subgrade has performed satisfactorily during the proofroll discussed in the Subgrade Preparation subsection, even though existing fill soils were encountered to depths of 3 to 8 feet. Provided that the pavement subgrade passes a proofroll, the risk of excessive settlement is low. However, if the pavement subgrade does not pass the proofroll, some undercutting and placement of controlled backfill will be required. We anticipate the new pavement will be of asphaltic concrete or Portland cement concrete. We expect that the proposed parking lot will generally be utilized for light duty traffic, and the driveways and loading and unloading areas will be utilized for light to medium duty traffic. Heavy traffic loads would be anticipated for areas near any dumpsters where garbage trucks would often cross. We recommend the pavement subjected to light traffic be underlain by a minimum of 8 inches of base course granular material, similar to Illinois Department of Transportation gradation CA-6. Assuming the pavement subgrade will consist predominantly of the cohesive soils and new fill prepared in accordance with the recommendations given in this report, an estimated CBR value of 3 could be used in proportioning a flexible pavement section. Similarly, an estimated modulus of subgrade reaction value equal to 100 pounds per cubic inch could be used for design of rigid concrete pavement sections. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 20 of 24 Some typical pavement sections used in this region of the country are given below which could be considered for preliminary estimating purposes. Other sections can also be considered. These sections assume a low volume of light vehicle loads (automobiles, vans, pickups, etc.). They should also be considered minimum thicknesses, and, as such, periodic maintenance should be anticipated. Final design sections should consider details such as final grades, traffic loadings, traffic volumes, the desired design life and any local, county or city codes. If you wish, we would be pleased to perform a detailed pavement section design using AASHTO or Asphalt Institute procedures when this information is available. It should also be noted that these sections do not consider if the binder course will be subject to construction vehicle traffic for an extended period of time. Some distress to the binder course and aggregate base could occur, if this is the case. TYPICAL PAVEMENT SECTIONS* Light Duty Heavy Duty ** (Parking Lots) (Drives) Portland Cement Concrete 5 inches 6 inches Full Depth Asphalt 5.5 inches 7 inches Combined Section: Asphalt 3 inches 4 inches Crushed Stone Base Course 8 inches 10 inches * All materials should meet the current Illinois Department of Transportation Standard Specifications for Road and Bridge Construction requirements. ** In areas of anticipated heavy traffic, delivery trucks, or concentrated loads, a minimum concrete thickness of 7 inches is recommended but should be evaluated further when loading conditions are known. Minimum design requirements for hot -mix asphalt (HMA) shall follow Article 1030.05 of the Standard Specifications for Road and Bridge Construction, effective April 1, 2016. During asphalt pavement construction, the wearing and leveling course should be compacted to a minimum of 93 percent of the theoretical density value. Prior to placing the granular material, the pavement subgrade soil should be properly compacted, proofrolled, and free of standing water, mud, and frozen soil. An important consideration with the design and construction of pavements is surface and subsurface drainage. Where standing water develops, either on the pavement surface or within the base course layer, softening of the subgrade and other problems related to the deterioration of the pavement can be expected. Furthermore, good drainage should reduce the possibility of the subgrade materials becoming saturated over a long period of time. We would be pleased to be of further assistance to you in the design of the project pavements by providing additional recommendations during construction of the project. Periodic maintenance of pavements should be anticipated. The subgrade parameters provided in this report consider that significant changes in the subgrade moisture content do not occur. To reduce the potential for changes in subgrade moisture, all paved areas should be sloped to provide rapid drainage of surface water and to drain water away from the pavement edges. Water that is allowed to pond on or Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 21 of 24 adjacent to the pavement can saturate and soften the subgrade soils and subsequently accelerate pavement deterioration. Granular base or subbase materials directly below pavement sections can also collect infiltrated surface water and soften the subgrade as well as increase the effects of frost action, both of which can be detrimental to pavements. For these reasons, where granular materials are used over a cohesive soil subgrade or where the groundwater level is within 3.5 feet of finished pavement subgrade, we recommend that consideration be given to using pavement underdrains hydraulically connected to the granular base or subbase to improve the pavement performance and extend its service life. General Construction Considerations We recommend that the subgrade preparation and construction of the proposed new building foundations and at -grade interior slabs -on -grade be monitored by an experienced geotechnical engineer or an authorized representative. Methods of verification and identification such as proofrolling, dynamic cone penetrometer (DCP) testing, hand auger probe holes, and test holes will be necessary to further evaluate the subgrade soils and identify unsuitable soils. If a shallow foundation system is to be implemented then the contractor needs to be prepared to extend shallow foundations to greater depths at isolated locations. Excavations - We recommend that excavations of the proposed new building foundations be monitored on a full-time basis by an experienced geotechnical engineer or an authorized representative to verify that the soil bearing strength and the exposed subgrade materials will be suitable for the proposed new building structures and are consistent with the soil boring log information obtained during this geotechnical exploration. All loose or soft soils in the subgrade or foundation excavation areas should be densified or removed before placing any concrete or fill. Accumulated water or runoff water at the base of the foundation excavations should also be promptly removed. Exposure to the environment may weaken the soils at the foundation bearing level if the excavations remain open for too long a time. Therefore, foundation concrete should be placed the same day that excavations are opened, when possible. If the bearing soils are softened by surface water intrusion or exposure, unsuitable soils must be removed and either replaced with properly compacted engineered fills or larger forms constructed to compensate for softened soils removal prior to placement of concrete. Groundwater Management - Assuming the proposed new buildings are supported on a conventional shallow foundation system consisting of spread and/or continuous strip footings, bearing on suitable, interpreted native, undisturbed soils or new, properly compacted engineered fill as discussed in the Analyses and Recommendations Overview, groundwater seepage should not be an issue during foundation excavations or overexcavating. If groundwater is encountered, we believe sump and pump system should be adequate to remove accumulated seepage from the bottom of excavations prior to placement of concrete or crushed aggregate. Concrete should not be placed in water. To reduce the potential for frost heave related problems forms should be used prior to the placement of foundation concrete. Subsurface Exploration and Geotechnical Engineering Analyses Proposed MPPD Lions Recreation Center 411 South Maple Street, Mount Prospect, Illinois SET Project No. 2144_1 April 22, 2025 Page 22 of 24 Drainage - We recommend adequate surface and subsurface drainage be considered in the design and construction of floor slabs. Where standing water develops, either on slab surfaces or within the subbase course layer, softening of the subgrade and other anticipated issues related to the deterioration of the floor slabs can be expected. Adequate drainage should reduce the possibility of the subgrade materials becoming saturated over a long period of time Site Safety - The contractor should avoid stockpiling excavated materials immediately adjacent to the excavation walls. We recommend that stockpile materials be kept back from the excavation a minimum distance equal to the excavation depth to avoid surcharging the excavation walls. If this is impractical due to space constraints, the excavation walls should be retained with bracing designed for the anticipated surcharge loading. Excavations should comply with the requirements of OSHA 29CFR, Part 1926, Subpart P, Excavations and its appendices, as well as other applicable codes. This document states that the contractor is solely responsible for the design and construction of stable, temporary excavations. The excavations should not only be in accordance with current OSHA excavation and trench safety standards but also with applicable local, state, and federal regulations. The contractor should shore, slope, or bench the excavation sides when appropriate. In no case should excavations extend below the level of adjacent structures or utilities, unless underpinning or other adequate support is provided. Site safety is the sole responsibility of the contractor, who shall also be responsible for the means, methods, and sequencing of construction operations. In summary, we recommend that the construction activities be monitored by SET Consultants to provide the necessary overview and to check the suitability of the subgrade soils for supporting the proposed new building foundations. Once final load criteria become available, SET Consultants needs to be contacted to review the recommendations presented herein.

STANDARD OF CARE This letter report has been prepared to aid in the evaluation of this Site and to assist the architect and/or engineer in the final design of this project. The scope is limited to the specific project and locations described herein and our description of the project represents our understanding of the significant aspects relative to soil and foundation characteristics. In the event that any change in the nature or location of the proposed construction outlined in this letter report are planned, we should be informed so that the changes can be reviewed and the recommendations of this letter report modified or approved in writing by the geotechnical engineer. It is recommended that all construction operations dealing with earthwork and foundations be reviewed by an experienced geotechnical engineer to provide information on which to base a decision as to whether the design requirements are fulfilled in the actual construction. If you wish, we would welcome the opportunity to provide field construction services for you during construction. The analysis and recommendations submitted in this letter report are based on the data obtained from the soil borings and tests performed at the locations as indicated on Figure 1 and other information referenced in this letter report. This letter report does not reflect any variations that may occur between the soil borings. In the performance of the subsurface exploration, specific information is obtained at specific locations at specific times. However, variations in soil conditions exist on most sites between soil boring locations and also such situations as groundwater levels can vary from time -to -time. The nature and extent of variations may not become evident until the course of construction. If variations then appear evident, after performing on -site observations during the construction period and noting characteristics and variations, a re-evaluation of the recommendations for this letter report will be necessary. Please note that SET Consultants does not warrant the work of laboratories, regulatory agencies, or other third parties supplying information used in the preparation of this letter report. The professional consulting services were performed in accordance with our agreed upon scope of work.

The measurements are relatively reliable when augering, without adding fluids, in a granular soil. In clays and plastic silts, the accurate determination of water levels may require several days for the water level to stabilize. In such cases, additional methods of measurement are generally applied. MONITORING AND MANAGEMENT PLAN Project Name: Lions Memorial Park Native Stormwater Retention Basin 1.0 PURPOSE Establish a maintenance program for the native basin area for the Lions Memorial Park. 2.0 SPECIES OF CONCERN The planted areas will be monitored annually for a three-year period to ensure successful establishment of the plantings. Following the first 3 years, the area will be regularly monitored for species management. The following invasive species are of highest concern should they be introduced to the area: Broadleaf Plants Alliaria petiolate Garlic Mustard Ambrosia spp. Ragweed Arctium spp. Burdock Carduus nutans Musk Thistle Centaurea maculosa Spotted Knapweed Cirsium arvense Canada Thistle Conium maculatum Spotted Hemlock Coronilla varia Crown Vetch Daucus carota Wild Carrot Dipsacus spp. Teasel Euphorbia escula Leafy Spurge Hesperis matronalis Dame's Rocket Lotus corniculatus Bird's -foot Trefoil Lythrum salicaria Purple Loosestrife Medicago spp. Alfalfa/Medick Melilotus spp. Sweet Clover Pastinaca sativa Wild Parsnip Polygonum cuspidatum Japanese Knotweed Solidago altissima Tall Goldenrod Solidago sempervirens Seaside Goldenrod Trifolium spp. Clover Typha spp. Cattails Grass -like Plants Agropyron repens Quackgrass Bromus tectorum Bromus japonicus Bromus inermis Phalaris arundinacea Phragmites australis Poa pratensis Cheatgrass Japanese Brome Smooth Brome Reed Canary Grass Common Reed Kentucky Bluegrass 3.0 PROTECTION AFTER INSTALLATION 1. Utilize stakes and string to protect the area from people and geese after installation. 4.0 NEAR TERM MANAGEMENT PLAN First Year. Mow the planted areas to a height of 6-8 inches 2-4 times during the early growing season or as needed to control non-native and invasive species after they have reached a height of 12 inches. Mowing (including weed whipping) shall take place prior to or when non-native and invasive species are flowering to prevent seed set and should be scheduled on 30 day intervals. Control undesirable plant species, when present in small quantities, by hand pulling prior to the development and maturity of the plant. Spot mowing is acceptable in areas where significant stands of weeds take control. Hand removal shall include the removal of all aboveground and belowground stems, roots and flower masses prior to development of seeds. Apply herbicide (as necessary) to non-native and invasive perennial species within the naturalized areas with appropriate herbicide. Management site visits should be conducted 8-10 times annually, starting in spring to control early cool season invasives. Regular site visits will take place 1-3 times per month in the growing season. 2. Second Year. Control of undesirable plant species during the second growing season shall consist primarily of herbicide application. Mowing (including weed whipping) shall be conducted two to four times during the early growing season and as needed to a height of 6 to 8 inches to prevent annual weeds from producing seed. Management site visits should be conducted 8-10 times annually. 3. Third Year. Undesirable plant species will be controlled (as necessary) by mowing (including weed whipping), hand pulling, and/or spot herbicide application. Continue to perform management site visits at least 5-6 times 2 annually during the growing season. This site would be difficult to burn given its proximity to schools and residential areas. In lieu of burning, a Fall mow/dethatching will be performed in the 3rd year to mimic a prescribed burn. This should be considered every 3-4 years based on the size of the area. 5.0 HERBICIDE APPLICATION This section applies to all management herbicide applications that are proposed to occur onsite. 1. Any person applying herbicide shall hold appropriate licensure for pesticide application in the state of Illinois. 2. Herbicide usage will vary based on site conditions and target species. It is the sole responsibility of the Applicator to evaluate the site and select the appropriate herbicide for both site conditions and target species in accordance with herbicide labeling. 6.0 LONG-TERM MANAGEMENT PLAN Management tasks should be preceded by a site inspection to determine if remedial measures are required and to recommend procedures to correct any deficiencies. The following management tasks should be completed annually, unless otherwise specified below: 1. Reseeding/Plug Installation: Following the first few years of establishment, any bare spots or areas that fail to fill in with desirable plants will be reseeded or filled with plugs grown from the original installation species list. Plugging and reseeding is recommended in Fall. 2. Herbicide Application: Selective herbicide to control invasive species should be completed 3-4 times annually. A certified and licensed pesticide applicator shall select herbicide, appropriate for the area of use (such as wetlands or other special management area), and shall apply the herbicide by the appropriate method, to prevent killing of desirable native species. Invasive and non-native species, and woody plant species not specified as part of the planting plan, shall be controlled by appropriate management practices of the approved plan. 3. Mowing: Selective mowing is a preferred method for control of annual non-native and invasive species to prevent seed proliferation. 3 4. Brush Clearing: Weedy shrubs are not a major concern for the site, but should any establish, they will be removed. After being cut, remaining stumps should be treated with an appropriate herbicide to prevent resprout, either through a basal oil treatment, hand wick applicator, or other approved method.

Easement provisions stating that the easements are being granted to the Village as well as the usage and restrictions should be added to the Plat prior to recording. I�•1 •�IP[•TTr!� 2. The proposed water service crossing the site east and south of the new building will not be owned & maintained by the Village, and so the proposed water main easement should be deleted from the plat. (Note: The applicant may wish to consider relocating the proposed water service to be farther away from the new buildings to facilitate future maintenance operations.) 3. Include provisions for the proposed sewer easements. 4. Confirm that there are no other utility easements needed (ComEd, Nicor, AT&T, etc.) by either having the utility companies sign the plat, or providing letters from the utility companies stating that there are no existing utilities on site, and no plans to install any in the future.

Sincerely, 701„., Antonia Lalagos Development Planner Community Development c: File From: Schreiner, Jake Sent: Friday, August 8, 2025 6:38 PM To: Shallcross, Jason Subject: Concerns for No Sidewalk on Streets for Park Plan Dear MP Community Development, was reviewing the planned unit development for Lions Park and was concerned that there were no sidewalk gap fillings for the existing gaps on both Lincoln and Maple Streets. This park will be a major pedestrian generator and is very close to downtown. Is there any way we could get these sidewalk gaps filled on the plans? Thanks Jake MINUTES OF THE REGULAR MEETING OF THE PLANNING & ZONING COMMISSION CASE NO. PZ-14-25 PROPERTY ADDRESS: PETITIONER: PUBLICATION DATE: REQUEST: MEMBERS PRESENT: MEMBERS ABSENT: STAFF MEMBERS PRESENT: INTERESTED PARTIES: Hearing Date: August 14, 2025 411 South Maple Street Mt Prospect Park District July 30, 2025 1) final plat of subdivision; 2) final PUD; 3) variation from the exterior yard setback requirements; and 4) a development code exception. Joseph Donnelly Ewa Weir Walter Szymczak Michael Fricano Richard Rogers William Beattie Donald Olsen None Antonia Lalagos— Development Planner Ann Choi — Development Planner Jason Shallcross — Director of Community & Economic Development Studio 222 Architects Inc Chairman Donnelly called the meeting to order at 7:01 PM. Commissioner Beattie made a motion seconded by Commissioner Szymczak to approve the minutes from the Planning and Zoning Commission meeting on July 24, 2025. The minutes were approved 7-0. After hearing three items of new business, Chairman Donnelly introduced case number PZ-14-25, 411 South Maple Street, a request for a final Planned Unit Development (PUD) to construct a new community recreation center and new outdoor recreational facilities including a swimming pool, pickleball courts, skate plaza, basketball court, outdoor game area, and seasonal ice rink at Lions Memorial Park, the subject property. Ms. Lalagos stated that the proposal requires the following zoning approvals: final plat of subdivision; final PUD; variation from the exterior yard setback requirements; and a development code exception. She described the subject property, Lions Memorial Park, as an existing 20.8-acre community park bounded by Maple Street to the west, Lincoln Street to the north, William Street to Planning & Zoning Commission Meeting — August 14, 2025 PZ-14-25 the east, and Sha Bonee Trail and Lions Park Elementary School to the south. Ms. Lalagos reported that the northwest side of the park contains most of the site improvements, while the southwest and east side of the park are predominantly open green space. She pointed out that the park amenities are connected to each other via asphalt walking paths that link to neighborhood sidewalks and the parking lot. Ms. Lalagos noted that the two existing vehicular access points into the subject property, on Maple and Lincoln Street, will remain. She explained that the park was established in 1955 and contains a recreation center, parking lot, and outdoor recreational amenities including a swimming pool, bandshell, tennis courts, ball fields, playground, and walking paths. Ms. Lalagos shared that Phase 1 updates to the parkwere completed in 2024 including the new playground, newwalking paths, and re -surfaced tennis courts. Ms. Lalagos summarized the Phase 2 work, which consists of demolition of the existing recreation center and swimming pool, and construction of a new recreation center and swimming pool, including a splash pad, water slides, bath house, and pool equipment building. She pointed out proposed outdoor recreational amenities including a skate plaza, basketball court, six picklebaLL courts, outdoor game area, and seasonal ice rink. Ms. Lalagos noted that one of the petitioner's goals in the site design is to provide direct access from the parking lot to the band shell and other outdoor amenities without having to circulate around the entire building, as with the current facility. She reported that the overall lot coverage of the subject property will increase to 33%, which is below the maximum allowable lot coverage of 75%. Ms. Lalagos explained that the proposed recreation center is set back 10.17' from the Lincoln Street property line, whereas the underlying zoning district (C-R) requires a minimum setback of 30' for the exterior side yard. She stated that the petitioner is requesting a variation from the exterior side yard setback requirements. Ms. Lalagos noted that staff agrees that the parcel shape and position of existing amenities pose a unique challenge when siting the recreation center, and concurs that the setback requirement would pose a hardship for the park district to create a practical site plan. She pointed out that the existing facility already has a non -conforming setback (17.85') and that staff does not believe that reducing the setback to 10' will alter the essential character of the neighborhood. Ms. Lalagos asserted that staff supports the variation request and finds that it is consistent with the overall goals of the PUD. Ms. Lalagos reviewed the elevations, showing that the two-story recreation center will be 42' tall and will be 55,700 square feet. She stated that the main entry will be located on the west elevation and will feature a metal canopy, and the fagade will be constructed of precast concrete panels with various finishes, including Norman -sized cast brick. Ms. Lalagos described the design elements including cast stone coping, woodgrain-finish metal panels, and a prefinished aluminum curtain wall system. She noted that the refuse enclosure and loading dock will be Located on the northeast elevation and will be screened with a six-foot tall solid panel sliding gate. Ms. Lalagos asserted that the PUD will approve signage consistent with what is shown on the plans, and any future relief requested for signage shaLL require an application for a minor amendment to the PUD. She displayed the floor plans, which showed a gymnasium, walking track, dance studio, multi - generational room, multi -purpose rooms, art studio, and preschool room. Ms. Lalagos described the pool area consisting of a bathhouse (5,352 SF), pool equipment building (1,304 SF), leisure pool with water slides (11,878 SF), splash pad (2,960 SF), and pool deck (22,480 SF). She noted that the maximum height of the water slide structure will be 31', measured at the Planning & Zoning Commission Meeting — August 14, 2025 PZ-14-25 top of the platform canopy. Ms. Lalagos displayed the other amenities, including six pickle ball courts to be installed to the east of the existing tennis courts, and a skate park and basketball court to be located east of the playground. She shared that the petitioner chose the skate park and basketball court locations because of existing site grading and to maintain open space in the center of the park for programming. Ms. Lalagos noted that the outdoor game courts and seasonal ice rink will be located south of the recreation center. Ms. Lalagos explained that the petitioner provided a parking study to estimate parking supply and demand for the site. She pointed out that the existing uses require approximately 800 parking stalls according to code, yet the subject property currently contains 179 parking stalls on site. Ms. Lalagos noted that the proposed uses require approximately 1070 parking stalls, and the petitioner is proposing 200 parking stalls on site. She emphasized that the code requirement calculates parking as if all uses were operating simultaneously and at maximum capacity, which would not happen. Ms. Lalagos stated that overall site maximum occupancy is increasing by approximately 13%, not considering seasonality and scheduling. She shared a table from the parking study showing comparable parks and their maximum capacity and available onsite parking, and noted that the subject property will have almost double the number of onsite parking stalls compared to the other parks. Ms. Lalagos reported on the petitioner's parking survey that assessed the parking available on weekdays and weekends in nearby parking lots and parking garages. She noted that the subject property is a short distance from Maple Street Parking Deck, and the park patrons can use the Lions Park Elementary School lot when school is not in session. She reported that the petitioner is exploring off-street parking agreements with Busse Automotive and Dasom Community Church. Ms. Lalagos explained that the parking study also included estimates of on -street parking available on streets within the study area, however, staff is requiring the petitioner to have a parking management plan that directs patrons to off-street parking options before resorting to on -street parking. Ms. Lalagos reviewed parking demand and shared Table 1, which estimates the parking deficiency according to the various methods used in the parking study. She reiterated that the minimum stalls required by the code represent all park uses operating simultaneously and at full capacity, which would not occur. Ms. Lalagos pointed to the petitioner's estimates of actual park activities taking place across the seasons, by time of day, versus maximum activity, showing demand to range from 154 vehicles on the low end, to 612 vehicles during a Thursday concert at the bandshell. The petitioner estimate shows that on a normal, non -concert day during the summer, parking demand will be roughly 250 vehicles. Ms. Lalagos explained that staff is requiring mitigation and monitoring measures to address potential parking overflow, including: a Parking Management Plan detailing parking accommodations for day-to-day activities, demonstrating adequate parking for the facility exists Largely onsite; a Special Event Parking Plan detailing additional off -site parking to be provided on nearby properties via off -site parking agreements, usage of the Maple Street Parking Deck, on - street parking, and information on how parking is coordinated for special events; and monitoring and reporting on the parking management plan, with a report required to be submitted to the Village Manager's Office after one full year of park operation. She stated that should the site experience regular overflow with a need for additional parking, the petitioner identified two Planning & Zoning Commission Meeting — August 14, 2025 PZ-14-25 4 locations on Lincoln and Maple Streets where angled parking could be added in the public right-of- way adjacent to Lions Memorial Park. Ms. Lalagos reported that Village staff is willing to explore this option should the need arise. She asserted that staff supports the proposed parking plan, based on the 200 stalls to be provided on site, along with the additional parking available in the Maple Street Parking Deck, on -street parking, and potential to secure parking agreements with nearby properties. Ms. Lalagos summarized the new landscaping proposed throughout the site to complement the new buildings, enhance the parking lot, and provide limited screening for certain recreational areas, all while prioritizing an open viewshed into the expansive green space. She indicated areas with notable new plantings including robust foundation plantings on the north facade of the recreation center; shade trees for the parking lot islands; evergreen screening on the west side of the tennis courts and south side of the skate park and basketball court; and water -tolerant species around and within the naturalized storm basin. Ms. Lalagos asserted that the intent of the landscape code is met through the overall design, making the full extent of perimeter landscaping unnecessary and allowing for visual and functional value in preserving open, unobstructed green space along the park's edges. Ms. Lalagos noted that the subject property has an existing detention area east of the playground and the petitioner is proposing an additional detention area on the east side of the site near William Street. She shared that the petitioner is requesting an exception from the development code to provide detention only for the areas being disturbed for this project, rather than the entire site, because detaining the stormwater for the entirety of the subject property would require an unreasonable amount of space and have a detrimental impact on the park and its ability to function. Ms. Lalagos stated that staff supports this development code exception due to the size and scale of the park and finds it is unreasonable to apply the code requirement to a 20-acre park property that is almost 70% open space. Ms. Lalagos reported that the subject property is comprised of two parcels totaling 20.8 acres. She explained that the parcels will be consolidated into one lot of record and utility easements will be granted over existing Village storm and combined sewers crossing the site. Ms. Lalagos shared that the Mt Prospect Park District has conducted extensive outreach regarding both Phase 1 and Phase 2 of the park renovation, which is documented on their webpage dedicated to the referendum project. She stated that the Village received one written public comment requesting to fill the sidewalk gaps on Lincoln and Maple Streets. Ms. Lalagos explained that when a unit of local government, such as a park district, comes to the Village with a zoning request, the Village should consider whether the requested relief furthers the statutory mission of the unit of local government and, if it does, give the requested relief some deference. She stated that when considering these questions, the Planning and Zoning Commission should rely on the referenced section of state law which outlines the statutory powers and duties of park districts. Ms. Lalagos summarized staff's findings, suggesting that the proposal will update aging public facilities and bring new recreation amenities to an existing community park, thereby supporting public health and general welfare of the community.

Except for the relief granted by the planned unit development, variation, and development code exception, compliance with all applicable development, fire, building, and other Village Codes and regulations is required. Ms. Lalagos stated that the Village Board's decision is final for the case. Hearing no questions for staff, Chairman Donnelly invited the petitioners to the stand. Chairman Donnelly swore in the petitioners and representatives as they appeared at the stand to answer questions. Commissioner Weir asked for more information about the relief requested for the recreation center setback and the width of the public sidewalk on Lincoln Street. Jeff Geldmyer, Project Engineer for Eriksson Engineering Associates, 145 Commerce Drive, Grayslake, Illinois, confirmed that the existing public walk near the building is a five-foot carriage walk. Chairman Donnelly asked if the walk would remain as is. Mr. Geldmyer confirmed that the walk would remain as is along Lincoln Street, and they will remove the portion that returns along the driveway because it is not ADA compliant and poses safety concerns. Chairman Donnelly asked if the sidewalk gaps would be filled in, referencing the public comment received. Mr. Geldmyer replied that they studied the pedestrian routes leading into and outside of the park and it is their opinion that there is an adequate and complete pathway system. He stated there is no intent to connect the gaps in these areas because of the safety concerns. Mr. Geldmyer explained that there are significant grading transitions in these areas that makes it challenging to install an ADA-compliant sidewalk, as well as concerns about damaging mature, healthy parkway trees. Commissioner Beattie asked where the sidewalk gaps are located. Mr. Geldmyer showed that the gaps are adjacent to the parking lot in the northwest corner of the site. He said they are extending a portion of public sidewalk south on Maple street to connect to the park district pathway system, but the sidewalk does not continue south across the driveway entrance. The engineer noted similar conditions on Lincoln Street where the sidewalk is not continuous. Commissioner Weir wanted to confirm that the sidewalk at the street is five feet wide and against the street, without a parkway. Planning & Zoning Commission Meeting — August 14, 2025 PZ-14-25 Mr. Geld myer replied yes, it is a carriage walk so it is immediately next to the road. Commissioner asked why the footprint of the building cannot be reduced to create more green space at the north side of the building. John Medea, Principal at Studio 222 Architects, 901 West Jackson Boulevard, Chicago, Illinois, replied that the building footprint is a function of the programming that the park district and community stakeholders desire. He stated that the size of the building is dictated by the programs, and the other elements like the pickleball courts and pool, are constrained by the baseball fields to the south. Mr. Madeja noted that the other important factor in site planning was the connection between the parking lot and the bandshell and the other park amenities; they wanted to keep the connection generous because they anticipate a lot of use, especially in the summer. He noted that the site is very tight, and they tried to provide as much buffer from Lincoln Street as they could. Mr. Madeja said they addressed the north fapade setback with more foundation landscaping. He pointed out that the north side of the building has a gymnasium inside, which tends to be long and uninterrupted, so they provided bay windows to break up the fagade and make it more inviting than a blank precast wall. Chairman Donnelly asked what the roof height is. Mr. Madeja stated that the predominant roof height is 36 feet to the top of the parapet, and there is an element that is set back further from the street that is 42 feet to the top of the parapet. He noted the actual roof height is 4 to 5 feet lower than that. Mr. Madeja reported they are going to screen the RTUs with the parapet. He said they provided screening exhibits that show the visibility of the RTUs from the property lines. Mr. Madeja explained that the intent is to screen the RTUs to the fullest extent possible. Commissioner Weir noted that stormwater management is governed by MWRD and asked if the relief is requested from Village code or MWRD code. Mr. Geldmyer responded that relief is sought only from the Village code, and they are in full compliance with MWRD requirements. He said they are accounting for the areas that they are developing, and not for all the green space and ballfields that they are not touching. Chairman Donnelly asked if there are any current flooding complaints from the neighbors. Mr. Geldmyer noted that the current site has no significant stormwater management. He stated there are existing small facilities, but the new detention will be the largest volume of storage there. Mr. Geldmyer confirmed it the project will provide notable watershed benefits for the local sewers. Commissioner Olsen asked if the site has problems with water detention now. Mr. Geldmyer replied that he was not aware of any ponding or flooding issues on the park district property outside of the areas that are intended to hold water. He stated that they will install a new stormwater detention basin on the southeast corner that is fully designed for the pool and recreation building addition. Planning & Zoning Commission Meeting — August 14, 2025 PZ-14-25 Commissioner Weir asked if they were implementing any sustainable landscaping plans on site to help with stormwater management or promote sustainable practices. Mr. Geldmyer replied that the stormwater basin will have native plantings. He indicated that they will meet volume control requirements by having some storage beneath the outlet of that system. Mr. Geldmyer shared that the new native plantings will blend in with the existing native plantings already in that area. Chairman Donnelly asked if the petitioner accepted all the conditions placed on the requests. The petitioner as a group replied yes. Commissioner Beattie asked for the timeline for completion. Matt Dziubinski, Director of Parks and Planning for Mt Prospect Park District, 1000 West Central Road, Mount Prospect, stated they are seeking park board approval in October and will start mobilizing in November with demolition beginning around that time. He said they will open the pool in May 2027. Mr. Dziubinski noted that the site will be under construction throughout 2026, but the intent is to leave the rest of the park open, such as the bandshell, tennis courts, etc. Commissioner Olsen expressed concern about the amount of parking with all the new amenities being added. He asked if they have enough parking. Steve Corcoran, Director of Traffic Engineering for Eriksson Engineering Associates, 145 Commerce Drive, Grayslake, Illinois, replied yes, there is enough parking, between the onsite lot, which is 200 spaces, the large amount of street parking around the park, as well as the Maple Street Parking Garage, and talking with the church and other business to get additional parking. Chairman Donnelly suggested they have enough onsite parking to run day to day operations, and when they have a concert, their peak time, people will park a block away. Commissioner Beattie stated that he was impressed by all the additions but also concerned because there are a lot more reasons to visit the park than there were a couple of years ago. He asked staff how many parking spaces there are in the Maple Street Parking Garage, which seems underutilized. Ms. Lalagos stated the garage has 262 spaces and confirmed it is a block away from the park. Ms. Corcoran stated that they visited the garage on a Saturday, and it was fairly empty, on the day of the week when they expect the highest use of the park. Chairman Donnelly pointed out that there is an option to add parking along Maple and Lincoln Streets if they need to. Hearing no further comments or questions, Chairman Donnelly closed the hearing and asked for a motion. Commissioner Beattie made a motion and Commissioner Szymczak seconded the motion to approve the requests as listed in the staff report and summarized here: Planning & Zoning Commission Meeting — August 14, 2025 PZ-14-25 10 "1. A final plat of subdivision titled "Lions Memorial Park Consolidation," subject to the conditions in the staff report; 2. A variation to reduce the exterior side yard setback from 30' to 10.2' on the segment of Lincoln Street abutting the north elevation of the recreation center, subject to the conditions in the staff report; 3. A development code exception from Sections 15.401(B) and 15.402(B) to provide stormwater detention only for the areas to be developed, subject to the conditions in the staff report; and 4.

UPON ROLL CALL AYES: Szymczak, Weir, Olsen, Beattie, Rogers, Fricano, Donnelly NAYS: None The Planning and Zoning Commission gave a positive recommendation (7-0) to the Village Board for the requests for the September 2, 2025 meeting. Chairman Donnelly asked if there were any citizens to be heard. Hearing no further discussion, Commissioner Beattie made a motion seconded by Commissioner Szymczak and the meeting was adjourned at 8:58 PM.

Our request is scheduled to go before the Village Board for the ordinances first reading on September 2nd, 2025. We are requesting that the Village Board waive the second reading, tentatively scheduled for September 16th, 2025, and to take final action at the September 2nd, 2025 Board meeting. The reasoning for this request is to ensure that the project aligns with permitting, available funding sources, and meets the timeline for the Park District's Park Board approval date which is currently set for October 15th, 2025. I appreciate your assistance in facilitating this request. Should you have any questions, feel free to contact me at (847) 956-6773 x460 or mdziubinski@mppd.org. Sincerely, Matt Dziubinski Mt.
