The proposal requires Village Board approval for conditional use approval for a preliminary and final planned unit development, final plat approval, and a development code exception. The proposal meets the requirements and standards related to the Village Code, and staff is supportive of the requests. Discussion BACKGROUND In November 2024, residents approved an $85 million referendum to address critical needs within the school district. According to the petitioner, these needs include the replacement of the existing middle school, which has struggled with outdated classrooms, limited space, and aging infrastructure. The proposed new facility is intended to provide a modern, accessible environment designed to support innovative instruction and meet the educational needs of today's students. According to the traffic impact study, the Lincoln Middle School currently serves 783 students in grades 6 through 8 with 91 staff members. Over the next six years, the student population is expected to decrease by 53 students to 730 students (-6.7%). PROPOSAL The petitioner, STR Partners LLC, on behalf of the Mount Prospect School District 57 (D57), proposes to construct a new 127,000 square foot replacement middle school, demolish the existing building, and complete related site improvements. The new school includes a three- story academic wing including the students' core classrooms, a two-story administration area, a learning resource center, experience classrooms, a storm shelter, gym, cafetorium, maintenance and support areas, and an outdoor learning/gathering space. Construction of the new facility is anticipated to begin in the fall of 2025, with completion targeted for August of 2027. The new school will be built while the existing school remains operational, with both structures coexisting on the site until the summer of 2027. Construction will run concurrently with the existing school until the summer of 2027. Demolition of the existing main school building and final site work are planned for completion by the summer of 2027. Conditional use approval is required as two principal structures will be present on the property during the transition period. The petitioner also requests relief from Sections 15.401(B) and 15.402(B) which require stormwater detention to be provided for the entire site when a new building is constructed. Site Plan: The new school is strategically sited with its tallest massing element — the nearly 50-foot-tall (48'-0"), 3-story academic wing — positioned at the center of the school property to minimize impacts on the adjacent residential properties. The building's massing is designed to step down appropriately to align with the scale of the surrounding neighborhood. A new, expanded parking lot with a queuing lane dedicated for parent drop-off/pick-up is proposed along Lincoln Street. Separate access for buses and delivery vehicles is provided north of the academic wing, within the outdoor play area. A continuous fire lane is provided around the new building and fire hydrants are distributed around the school to ensure adequate fire protection. The development also provides underground stormwater volume control and detention storage north of the school. Open green space will be preserved along the west and north portions of the site for use by physical education classes. A discus cage is located at the northeast corner of the subject property. Following the demolition of the existing school and associated parking areas, a 200-meter track and new athletic field will be constructed along the east side and southeast corner of the site and will offer accessible recreational amenities to the community during non -school hours. Traffic and Parking: The Village requires schools serving grades K through 8 to provide one parking space per employee, plus eight visitor spaces. Based on the staffing level of 91 employees, the school is required to provide 99 parking spaces. The current parking lot provides a total of 77 parking spaces. The proposed site plan includes a total of 106 parking spaces, exceeding the Village's requirement and representing a net increase of 29 parking spaces compared to the current condition. The additional parking will significantly improve overall site functionality and better accommodate daily operations and visitors. According to the Petitioner's project description, long-term staff parking will be located in the large south parking lot, while visitor parking will be designated in the smaller southwest lot for ease of access. The north lot will be used exclusively for bus drop-offs and pick-ups, with no long-term bus parking on site. An additional 9 parking spaces at the northeast corner of the building will be reserved for maintenance and food service personnel. Building Elevations: The proposed building elevations feature a contemporary institutional design, characterized by clean lines, a mix of durable materials, and articulated massing. The exterior incorporates brick masonry, fiber cement panels with a wood -like appearance, aluminum storefront systems, and aluminum -composite metal paneling, which provide visual interest and durability. The fagades are articulated through changes in plane, material transitions, and patterns to help break up the overall massing. The color palette consists of warm, neutral tones. Rooflines are varied in height, while all rooftop mechanical units will be screened from view. Additionally, ground -mounted mechanical/utility equipment, as well as the trash enclosure, will be screened with brick masonry walls. The gradual stepping down of taller building elements to shorter elements, organized according to the function of the spaces, is appropriately scaled to the surrounding single-family residential neighborhood, resulting in contextually sensitive massing and a pedestrian -friendly scale. Landscaping: The existing landscaping will remain along the north, west, and south property lines and additional canopy trees have been added along the west property line. Perimeter landscaping, consisting of a variety of existing deciduous trees, new canopy trees, and a combination of deciduous and evergreen shrubs, will be provided along the south property line. A considerable amount of foundation landscaping will also be provided along portions of the building's north, south and east facades. The petitioner is requesting relief from strict conformance of the foundation and perimeter landscaping requirements. Foundation landscaping will not be provided along most of the north and the entirety of the west elevations since these facades face private property. While a 6-foot-tall screen/buffer is required along the length of the rear and interior side yards, a shorter screen/buffer will be provided only in select areas at the southwest and northeast corners of the property, in response to requests from specific adjacent property owners (see section of staff report titled "Resident Concerns"). This approach also helps preserve the openness and accessibility of the school's open spaces, which are valued by neighboring residents. Additional trees have been added to the northeast as well as providing additional landscape screening around the discus cage. Relief is also requested from the requirement to provide an even 50/50 distribution of deciduous shrubs and evergreen shrubs. The petitioner requests a mix of 70/30 mix of deciduous to evergreen shrubs due to the number of plantings proposed and their proximity to pavement areas that will be subject to de-icing agents, as these conditions are not conducive to healthy evergreens. Lastly, relief is requested from the requirement to provide planting islands that are 120 square feet in area in the southwest parking lot, and to provide planting islands for every seventeen parking spaces in a parking row in the south parking lot to maximize the number of parking stalls and facilitate snow removal. In place of the three planting islands in the south parking lot, a striped pedestrian pathway will be provided to allow safe access through the lot. Lighting: The petitioner provided the photometric plan for the existing site. The petitioner is proposing nineteen light poles that illuminate the drive aisles, parking lots and fire lane, twenty-one exterior wall -mounted light fixtures on the facades of the new building, and four uplights around the monument sign along Lincoln Street. A fully compliant photometric plan will be required as part of the building permit submittal. Signage: The petitioner intends to install one wall -mounted sign and one canopy sign on the south elevation facing Lincoln Street. A new monument sign is also proposed just west of the Lincoln Street driveway and a freestanding sign is proposed along the Can Dota Avenue frontage just east of the track & field. Per the petitioner, relief is requested for: items of information as Lincoln Middle School is a very common school name in Illinois, while the proposed monument sign will include the full district name for identification, and the sign copy contains 12 items of information exceeding the 10 items permitted by code; orientation for the freestanding sign at the track & field (honorary naming will be visible from both sides and parallel with the long jump to best utilize the limited green space and maintain student safety); and sign surface area for the canopy sign (18.5 square feet) which exceeds the 4 square feet permitted for secondary signage. Any future relief requested for signage shall require an application for a minor amendment to the PUD. Phasing: The project is estimated to begin in October of 2025, and the existing school building, south side drop-off lane, and the east side drive and parking area will remain active during construction. The new school building is anticipated to start in October of 2025 and will be completed by May of 2027. The new below -grade detention system will be installed during the summer of 2026. The demolition of the central and southern portions of the school will be commence in May/June of 2027. All building demolition will be completed by August of 2027. The new south side parking lot will begin once the central and southern portions of the existing school have been demolished. The new south parking lot will be completed in August of 2027. The new east side bus drive/loop and paved areas will commence mid- to late - summer of 2027 and will be completed in the fall of 2027. The east side of the track and green space will commence after the demolition of the existing school and will continue through the fall of 2027. A phasing schedule including diagrams are included with this staff report. Other Departments: The Public Works department expressed concerns related to turning movements from the school's new driveway onto Can Dota Avenue. The short 75-foot offset between West Milburn Avenue and the proposed driveway may potentially lead to collisions between a bus and another vehicle performing simultaneous left turns. When making a left turn onto Can Dota Avenue, stopping distances may be insufficient to avoid collisions if vehicles turn simultaneously. At 15 mph, passenger vehicles require about 80 feet to stop, increasing to 115 feet at 20 mph; buses require even longer distances. This limited space increases the risk of conflicts. Because of this safety concern, Public Works remains committed to prohibiting left turns out onto Can Dota Avenue. Staff recommends that the left turn restriction be included as a condition for the Planning and Zoning Commission's recommendation to the Village Board. Building & Inspection Services and the Fire Department did not have any conditions of approval for the zoning request. PLAT OF SUBDIVISION (CONSOLIDATION AND VACATION) The subject property encompasses five parcels and four parcel identification numbers (PINS): • Parcel 1: 08-11-214-037-0000; • Parcel 2: 08-11-214-002-0000; • Parcel 3: 08-11-215-011-0000; and • Parcel 4: 08-11-214-036-0000 • Parcel 5 does not appear to have an assigned PIN. A final plat to consolidate the lots into a single lot is required so that the application of setbacks and other bulk regulations is straightforward. The plat shows that the southern half of the vacated portion of Milburn Avenue west of Can Dota Avenue is included as part of the school district property. Additional right-of-way along the Lincoln Street frontage will be dedicated to the Village, allowing a consistent right-of-way width across the Lincoln Street frontage, and allows the existing public sidewalk to be located on public property. This new dedication also causes the existing monument sign to be in the public right-of-way and the project will be conditioned to allow the monument sign to remain until such time the sign is relocated onto school property. Resident Concerns: The Petitioner has provided regular project updates through meetings and the school website to maintain an open dialogue with the surrounding community. Specific comments include: The property owner at 806 West Lincoln Street (Lot 25) would like to preserve as much green space as possible along the property owner's east property line and requested the planting of evergreen shrubs no taller than 3 to 4 feet. The property owner specifically requested that no trees be planted along the east property line, as they would obstruct sunlight to the property and to the existing greenhouse on the owner's property. • The property owner at 220 Can Dota Avenue expressed concerns regarding privacy, the condition of existing trees along the perimeter of their property, and the visibility and activity surrounding the discus cage. In response, the property owner has requested the installation of fencing and additional landscaping to provide screening. The property owner has also requested that District 57 reach out to ComEd to explore the potential for replacing certain utility poles. • The property owner at 305 Can Dota Avenue raised several concerns, including the alignment of the proposed school driveway in relation to their own driveway, the continuation of parking restrictions during school hours on the 300 block of Can Dota Avenue, and whether modifications to the drop-off and pick-up procedures will be implemented for the 2025 school year. The property owner has also requested clear and timely communication going forward regarding project milestones. Aside from these three properties, no additional concerns have been received by Village Staff by neighboring residents regarding the proposed school redevelopment as of the writing of this report. Feedback from neighboring property owners was taken into consideration, and the plans are being finalized accordingly to address these concerns. STORMWATER DETENTION AND DEVELOPMENT CODE EXCEPTION Sections 15.401(B) and 15.402(B) of the Village Code require that stormwater detention be provided for the entire site when a new building is constructed. The Engineering Division indicated that it would seem appropriate that the easement area over the Village's sanitary overflow system located at the west end of the site be exempted from counting towards the entire site. Any area to be exempted would require a variation from the Village Code granted by the Village Board, and Schedule L to be included in the MWRD permit application. The Engineering Division reviewed the request and supports the requests. Development Code Exception Standards: Section 15.109 permits the Planning & Zoning Commission to recommend approval of exception to the development code regulations in cases of 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 request must meet the standards for an exception, which are listed in Section 15.109 and are summarized as follows: • A hardship due to the physical surroundings, shape, or topographical conditions of a specific property not generally applicable to other properties in the same zoning district and not created by any person presently having an interest in the property; • Lack of desire to increase financial gain; and • Protection of the public welfare, other property, and neighborhood character. Per the petitioner, the site contains significant existing Village infrastructure, including a sanitary overflow system, which will remain undisturbed and lies outside the development area. Due to these unique encumbrances, the school district is requesting relief from including these portions in the total area calculated for stormwater detention, as doing so presents a hardship, particularly given the site's use as a publicly funded school. The request aims to comply with MWRD's Watershed Management Ordinance. The petitioner has stated that the development will meet all MWRD stormwater requirements and will significantly enhance local drainage and reduce runoff impacts on Village sewer infrastructure. Staff finds that the development code exception standards have been met and supports the request for an exception. 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 also need to consider whether any condition of approval or whether a denial of the application would frustrate or thwart the obligations imposed by State laws on the unit of local government. 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 additional consideration, for District 57's application the Planning & Zoning Commission considered: 1. The relationship of the new school to the education obligations of District 57; 2. The plausible alternatives for any of the relief requested; and 3. The negative effects on District 57 if relief is not granted. Some parts of the Illinois School Code applicable to District 57 and potentially relevant here: 1. Areas of education taught, 105 ILCS 5/27-1, "The State of Illinois, having the responsibility of defining requirements for elementary and secondary education, establishes that the primary purpose of schooling is the transmission of knowledge and culture through which children learn in areas necessary to their continuing development and entry into the world of work. Such areas include the language arts, mathematics, the biological, physical and social sciences, the fine arts and physical development and health. Each school district shall give priority in the allocation of resources, including funds, time allocation, personnel, and facilities, to fulfilling the primary purpose of schooling." 2. Elementary school civics course of study, 105 ILCS 5/27-3.10, "In addition to the instruction required to be provided under Section 27-3 of this Code, every public elementary school shall include in its 6th, 7th, or 8th grade curriculum, beginning with the 2020-2021 school year, at least one semester of civics education, which shall help young people acquire and learn to use the skills, knowledge, and attitudes that will prepare them to be competent and responsible citizens throughout their lives. Civics education course content shall focus on government institutions, the discussion of current and societal issues, service learning, and simulations of the democratic process. Civics education in 6th, 7th, or 8th grade shall be in accordance with Illinois Learning Standards for social science. Additionally, school districts may consult with civics education stakeholders, deemed appropriate by the State Board of Education, with regard to civics education curriculum for 6th, 7th, or 8th grade." 3. Physical education and training, 105 ILCS 5/27-5, "Physical education and training. School boards of public schools and the Board of Governors of State Colleges and Universities shall provide for the physical education and training of pupils of the schools and laboratory schools under their respective control, and shall include physical education and training in the courses of study regularly taught therein. The physical education and training course offered in grades 5 through 10 may include the health education course required in the Critical Health Problems and Comprehensive Health Education Act." 4. Courses in physical education required, 105 ILCS 5/27-6(a), "Pupils enrolled in the public schools and State universities engaged in preparing teachers shall be required to engage during the school day, except on block scheduled days for those public schools engaged in block scheduling, in courses of physical education for such periods as are compatible with the optimum growth and developmental needs of individuals at the various age levels except when appropriate excuses are submitted to the school by a pupil's parent or guardian or by a person licensed under the Medical Practice Act of 1987 and except as provided in subsection (b) of this Section." The school district is requesting zoning relief for: building height, perimeter landscape screening, foundation landscaping, signage, storm water detention, planting islands, planting ratios, and the track & field encroachment into the exterior side yard. D57 has indicated that granting the requested relief serves the public interest, as the proposal seeks to balance zoning and development requirements with the district's educational objectives and fiscal responsibilities. The district notes that the project is funded by the community and must remain within a limited budget while still meeting the needs of students and staff. PUBLIC COMMENT Public comment letters were received from nearby residents. A written letter submitted by a resident of Can Dota Avenue raised concerns about the planned service driveway, its location directly opposite their home, and its intended use. The letter also expressed frustrations with communication, construction staging, dust and debris, and delays in related street and water main repairs. The resident requested that no zoning relief be granted until clearer communication and stronger accountability measures are in place. Village staff and the school district separately reached out to the resident and explained that the roadway construction work on Can Dota Avenue is part of a larger Village project that includes the installation of more than 2,000 feet of pipe, water services, and hydrants, along with new curb and sidewalk, pressure and chlorination testing along with general cleanup before paving begins. The roadway construction project was estimated to complete by mid -August before the start of the school year, and is unrelated to the school district's undertaking of constructing a middle school. Residents of the 400, 500, and 600 blocks of South Na-Wa-Ta Avenue submitted a signed petition requesting that no construction traffic be routed onto their street during the entire project. The homeowners emphasized their support for the school project but expressed concern about preserving recently completed curb and asphalt improvements, as well as avoiding excess construction -related noise in front of their homes. Village staff will determine a construction access route during the building permit process and communicate with the contractor and the police department during construction to restrict construction vehicles on certain roads. PUBLIC HEARING The Planning and Zoning Commission reviewed the proposal for the replacement of Lincoln Middle School at 700 and 804 West Lincoln Street. Commissioners raised questions regarding construction parking availability, rooftop mechanical equipment height and noise impacts, adequacy of south -facing glazing and shading, and circulation of buses and parent drop-off traffic. Concerns were also discussed regarding contractor parking on neighborhood streets and the need for construction management plans to mitigate neighborhood disruption. The Planning and Zoning Commission emphasized that all rooftop units must remain screened from public view and that construction operations remain within ordinance -compliant hours. Several residents provided testimony focusing on potential impacts to their properties. Concerns included the adequacy of fencing and landscaping along the athletic fields, lighting spillover into adjacent yards, on -street contractor parking during construction, and the potential for flooding given existing drainage issues. Neighbors on Milburn Avenue and We Go Trail highlighted long-standing stormwater problems, and residents requested assurance that the new detention facilities would prevent water from ponding in their backyards. The petitioners responded that a new underground detention system will be constructed to MWRD standards, photometric plans will ensure no light trespass, and landscape screening rather than fencing will be used to balance openness with buffering. Following the discussion, the Planning and Zoning Commission unanimously recommended approval of the final plat of subdivision, conditional use for a preliminary and final planned unit development and a development code exception by a vote of 7-0 at the public hearing held on August 14, 2025. REQUEST TO WAIVE FEES As part of the planning and approval process, Village fees are associated with platting, building permits, and zoning request applications. These fees include platting ($250), zoning ($1500), code exceptions ($250), and permit fees for the project, including the estimate of construction costs for Village Board consideration. The estimated site cost is $8,600,000 with a total estimated construction cost of $66,250,000. School District 57 respectfully requests that these fees be waived for the district's upcoming construction projects. REQUEST TO WAIVE SECOND READING The Petitioner requests that the Village Board waive the second reading and take final action at the September 2, 2025, meeting. Alternatives 1. Approve a final plat of subdivision titled "Lincoln Consolidation" for 700 and 804 West Lincoln Street, Case No. PZ-10-25; 2. Approve a development code exception from Sections 15.401(B) and 15.402(B) to exempt the easement area over the Village's sanitary overflow system located at the west end of the site from counting towards the entire site; 3. Approve a conditional use for a preliminary and final planned unit development (PUD) to construct a 127,000-square-foot middle school, and complete related site improvements at 700 and 804 West Lincoln Street, Case No. PZ-07-25, subject to the conditions listed in the attached ordinance. 4. Approve a waiver of the platting, zoning, code exception and non-refundable permit fees. 5. Action at the discretion of the Village Board. Staff Recommendation Approve: 1. A final plat of subdivision titled "Lincoln Consolidation" for 700 and 804 West Lincoln Street, Case No. PZ-10-25; 2. A development code exception from Sections 15.401(B) and 15.402(B) to exempt the easement area over the Village's sanitary overflow system located at the west end of the site from counting towards the entire site; 3.

III III III i III „„� (3III III „ IIIIIIIIIII t III III NI S ASS =IA I°°°' IIIIIIIIII S ui ° INTRODUCTION Eriksson Engineering Associates, Ltd. (EEA) was retained by Mount Prospect School District 57 and STR Partners LLC to conduct a traffic and parking study for Lincoln Middle School at 700 W Lincoln Street in Mt. Prospect, Illinois. Lincoln Middle School currently serves 783 students in 6th thru 8h Grade. The school district plans to replace the existing school building with a new building on the same site. The purpose of the study was to observe the existing traffic patterns around the school, to determine the traffic characteristics of the existing and future school, to review its parking needs, and to develop roadway and parking recommendations as needed. EXISTING CONDITIONS Site Location and Area Land -Uses Lincoln Middle School is located at 700 West Lincoln Street in Mt. Prospect, Illinois. The school site is bounded Lincoln Street to the south, Can -Dots Avenue to the east, and single-family homes to the north and west. It is located within a single-family neighborhood with the Mt. Prospect Golf Club to the southwest. Figure 1 illustrates the site location and the surrounding land -uses and roads. Pedestrian Routes Sidewalks are provided on both sides of the public streets near the school. Entrance to the school via sidewalks are located along the east and south side of the school. The all -way stop controlled intersection of Lincoln Street at We Go Trail has crosswalks painted on the south, east, and north legs of the intersection. The intersection of We Go Trail at Pendleton Place has pedestrian crossing signs and crosswalks on the north and south leg with a stop sign on the west leg. At the intersection of We Go Trail and Milburn Avenue there are crosswalks painted on the north and east leg of the intersection with a stop sign on the east leg of. The intersection of Lincoln Street and Na Wa Ta Avenue has crosswalks painted on the south and west legs of the intersection and has pedestrian crossing signs on the east and west leg of the intersection with stop signs on the north and south legs of the intersection. The all -way stop controlled intersection of Can-Dota Avenue and Lincoln Street has crosswalks painted on all four legs of the intersection. The intersection of Can-Dota Avenue and Milburn Avenue has crosswalks painted on the east and south leg of the intersection and has pedestrian crossing signs on the north and south leg of the intersection with a stop sign on the east leg of the intersection. The intersection of We Go Trail and Milburn Avenue has crosswalks painted on the north and east leg of the intersection with a stop sign on the east leg of the intersection. Roadway Characteristics A description of the area roadways accessing the school is provided below: Lincoln Street is an east -west local roadway with one travel lane in each direction and has a posted speed limit of 25-mph with a 20-mph school speed limit approaching the school. An all -way stop controlled intersection is provided at We Go Trail and at Can-Dota Avenue. A two-way stop -controlled intersection is located at Na Wa Ta Avenue/drop-off loop exit. The one-way student drop-off/pick-up loop is located along Lincoln Street. Parking is permitted on the south side of the road and is restricted on the north side of the road along the school front from the hours of 7:00 AM to 3:00 PM. It is under the jurisdiction of the Village of Mount Prospect. We Go Trail is a north -south residential roadway with one travel lane in each direction and a posted speed limit of 25-mph. A T-junction stop controlled intersection is provided at its intersection with Milburn Avenue with the stop sign located on the east leg. At its intersection with We Go Trail, there is a crosswalk on the north and south legs of the intersection with pedestrian crossing signs on the north and south legs of the intersection. It is under the jurisdiction of the Village of Mt. Prospect. Can-Dota Avenue is a north -south local roadway with one travel lane in each direction with a posted speed limit of 25-mph. T-junction stop controlled intersections are provided at both Milburn Avenue intersections with Con- Dota having the right of way. The student drop-off/pick-up loop is provided along Can-Dota with one entrance to the loop and two exists. Parking is allowed on both sides of each street. Parking is restricted on the east side of Lincoln Middle School June 4, 2025 Traffic and Parking Study 1 P.

It is under the jurisdiction of the Village of Mount Prospect. Milburn Avenue is an east -west local roadway with one travel lane in each direction with a posted speed limit of 25 mph. It has two T-junction intersections with Can-Dota Avenue which causes Milburn Avenue to split with the west leg T-junction intersection occurring around 250 feet north of the east leg T-junction intersection. It is under the jurisdiction of the Village of Mount Prospect. Figures 2 illustrates the existing traffic control and travel lanes around the school. Existing Traffic Volumes Weekday morning arrival (7:00-9:00 AM) and afternoon dismissal (2:00-4:00 PM) traffic counts were conducted at the intersections around the school during good weather in March of 2025. Peak -hours of traffic occurred from 7:30 to 8:30 AM and 2:45 to 3:45 PM which coincides with the school's 7:45 AM start and 2:45 PM dismissal times. The existing traffic volumes are shown on Figure 3A and included in the Appendix. Figures 3B and 3C separate the school and non -school volumes. Figure 4 summarizes the existing pedestrian and bicycle volumes School traffic volumes would be slightly higher during poor weather with less students walking. School Procedures and Observations Arrival and dismissal observations were performed on May 3rd, 2025. Weather conditions were overcast, and temperature was in the mid-50s with no precipitation. During arrival and dismissal times, there are crossing guards present at the intersections of Lincoln Street at Na Wa Ta Avenue, Lincoln Street at Can-Dota Avenue, and Can-Dota Avenue at east leg of Milburn Avenue. Can-Dota Avenue is restricted from turning left into the east parking lot. School buses approach from Lincoln Street into the west school lot where the students are dropped off. In the afternoon, the school buses load students at the west lot and departed along Lincoln Street. There were nine large buses and one small bus. In the morning most parents were observed dropping off students at the east parking lot loop which caused congestion on Can-Dota Avenue and its intersections with the west and east leg of Milburn Avenue. As a result, students were dropped off on the east side of Can-Dota and did not use a crosswalk to cross the road. Traffic was stacking along Can-Dota in the southbound direction from its intersections with Lincoln and Milburn Drive. This congestion caused bottlenecking along Can-Dota Avenue near the intersection of Lincoln Street. Stacking was also observed at the pick-up/drop-off loop, continuing past the intersection of Lincoln Street and Can -Dots Avenue. Parents were observed dropping off students on the south side of Lincoln Street with students crossing via crosswalk. Minimal traffic delays were observed along Lincoln Street. Students were consistently crossing at intersections where crossing guards were present. Minimal to no traffic was observed along Milburn Avenue and We Go Trail. Curbside activity at Can-Dota Avenue and Lincoln Street was higher in the afternoon than in the morning. Parents arriving early were stacking along Can -Dots Avenue which ran from the curbside pickup at the east lot to its intersection with Dresser Drive. Other parents were observed to have parked along the Milburn Avenue west and east legs, Can-Dota south of Lincoln Street, and Na Wa Ta Avenue however this did not cause traffic issues on those roads. Vehicles parked on Na Wa Ta Avenue and Can-Dota Avenue south of Lincoln Street caused one way traffic on those roads. Parents were also observed to be parked along Lincoln Street which stacked from the south pick-up/drop-off loop to its intersection with Wa Pella Avenue. After dismissal, many students walked to their parents' vehicles while the rest of the students walked/biked home or were picked up via the east lot and south drop-off/pick-up loop. Traffic along Lincoln Avenue operated well . Traffic along Can -Dots experienced congestion and vehicles parked along the west side of the street with no driver were observed causing bottlenecking near its intersection with Lincoln Avenue. Similar to the morning, heavy congestion was observed at the intersections of Milburn Ave east and west leg with Can -Dots Avenue. We Go Trail and Milburn Avenue operated with little to no traffic. A low volume of pedestrians was observed using the sidewalks entering the school property at We Go Trail and Pendleton Plane and at Milburn Avenue at See Gwun Avenue. Peak traffic activity lasted 20 minutes before and after school. Overall, the school traffic conditions were busy at peak times and flowed well other than congestion along Can -Dots Avenue and its intersections with Milburn Avenue. Most students used the crosswalk to reach the school however few students were observed not using the crosswalk at Can-Dota Avenue during drop-off. The peak westbound queuing on Lincoln Street lasted about 10 minutes.

Over the next six years, the student population is expected to decrease by 53 to 730 students (-6.7%). The number of school buses will remain at nine. Currently 434 students ride the school buses (55%). In the future, 420 students are expected to use the bus (57%). School Trip Generation and Distribution Traffic estimates were made for the projected number of students using the traffic counts at the current school. The rate of vehicle trip generation was applied to the decreased student population (-7%) with the results shown in Table 1. Table 1 School Traffic Volumes Scenario Morning Arrival Afternoon Dismissal In Out I Total In Out Total Existing 783 Students 228 221 449 139 138 277 Reduction of 53 Students -21 -20 -41 -8 -8 -16 Total 730 Students 207 201 408 131 130 261 The directional distribution for school traffic is based on the existing school traffic counts and is shown in Table 2 and on Figure 5. Sixty-seven percent of the school traffic was to and from the east on Lincoln Street and the remaining thirty-three percent were from Can-Dota Avenue. Thirty percent of the school traffic was to the north and south on Can-Dota Avenue, thirty percent was to the east and west on Lincoln Avenue. Table 2 Directional Distribution Direction Distribution South on Can-Dota Avenue 25% North on Can -Dots Avenue 5% West on Milburn Ave 15% West on Lincoln Street 15% East on Lincoln Street 15% North on We -Go Trail 5% South on We -Go Trail 15% North on Na-Wa-Ta Avenue 5% Total 100% Trip Assignment The future vehicular trips that are generated by the school were distributed to the area roadways based on the site plan, projected school volumes, regional traffic growth, and the directional distribution analysis. Figure 6 illustrates the site traffic generated by the school and its assignment on the road system. The new school parking lot and student loading area will direct more traffic on Lincoln Street. Buses will use Can-Dota Avenue to access the bus loading area on the north side of the school. It is anticipated that some parents will use the west side of the Can -Dots Avenue south of the bus entrance to drop-off or pick-up students. Traffic projections were estimated for a period of five years in the future after construction (Year 2031). Figure 7 shows the total traffic volumes.

The intersection and individual traffic movements are assigned a level of service (LOS), ranging from A to F based on the control delay created by a traffic signal or stop sign. Control delay consists of the initial deceleration delay, queue move -up time, stopped delay, and final acceleration delay. LOS A has the best traffic flow and least delay. LOS E represents saturated or at capacity conditions. LOS F experiences oversaturated conditions and extensive delays. The Highway Capacity Manual definitions for levels of service and the corresponding control delay for both signalized and unsignalized intersections are shown in Table 3. Table 3 Level of Service Criteria for Intersections Level of Service Description Control Delay (seconds/vehicle) Signals I Stop Signs A Minimal delay and few stops <10 <10 B Low delay with more stops >10-20 >10-15 C Light congestion >20-35 >15-25 D Congestion is more noticeable with longer delays >35-55 >25-35 E High delays and number of stops >55-80 >35-50 F Unacceptable delays and over capacity >80 >50 Source: Highway Capacity Manual Capacity analyses were conducted for each intersection using the computer program Synchro to determine the existing operating conditions of the access system. These analyses were performed for the school's peak arrival and dismissal periods. Table 4 shows the existing and future level of service results for each intersection. Copies of the capacity analysis summaries are included in the Appendix. Overall, there will be minor changes in intersection operating conditions in the future with the reduced school volumes and change if traffic flow. Lincoln Street at We Go Trail This all -way stop controlled intersection is currently operating at an excellent level of service with minimal delay. After upgrades to the school, the intersection will continue to operate at an excellent level of service. No upgrades are required at this intersection. Lincoln Street at Can-Dota Avenue This all -way stop controlled intersection is currently operating at a good level of service with low delay. Congestion is most present at the southbound stop due to a high volume of parents dropping off students in the southbound direction during pick-up and drop-off hours. After upgrades to the school, the intersection will continue to operate at an excellent level of service. No upgrades are required at this intersection. We Go Trail at Milburn Avenue This two-way stop -controlled intersection is currently operating at an excellent level of service. After upgrades to the school, the intersection will continue to operate at an excellent level of service. Lincoln Middle School June 4, 2025 Traffic and Parking Study 13 P.

The intersection overall will operate at a good level of service with minimal delay. Parking Parking required by the Village of Mount Prospect for schools serving Grades K thru 81h is one space per employee plus eight spaces for visitors. The required parking for the current and proposed school is 99 parking spaces. National parking data is available from the Institute of Transportation Engineers (ITE) in their publication Parking Generation, 6th Edition for Middle School/Junior High (Land Use Code 522). The peak demand using the ITE data is 78 vehicles for the current school and 74 vehicles in the future. Parking counts were conducted on Thursday March 13, 2025, at the school that found 40 vehicles parked in the west lot, 36 vehicles in the east lot, and six vehicles parked on -street by the school for a total of 82 vehicles. The school currently has 91 staff. While the number of students is expected to decrease, the staffing at the school will remain at 91 employees. Based on the parking surveys, the parking demand would stay at 82 vehicles. Lincoln Middle School June 4, 2025 Traffic and Parking Study 14 P.

The east lot has 36 regular and 2 accessible spaces. The west lot has 41 regular and 2 accessible spaces. There are a total of 81 spaces on site. The current school is short 16 spaces from the 99-space zoning requirement. For the new school plan, there will be 12 regular spaces on the north side of the building and 97 regular with 5 accessible spaces in the new main lot on Lincoln Street. The total on -site parking supply is 114 parking spaces which exceeds the 99-space zoning requirement, ITE demand of 74 vehicles, and the parking survey data with 82 parked vehicles. The proposed parking supply will meet the needs of the school. Parking for special events at the school can be accommodated by a combination of off-street parking and on -street parking by the school. Five accessible spaces are provided and meet the ADA code requirements. Lincoln Middle School June 4, 2025 Traffic and Parking Study 15 P. III III III I III „„� G III III „ IIIIIIIIIII III III NI G ASS =IA I°°°' IIIIIIIIII S ui ° Vehicle Queueing The proposed changes with the new school building and on -site parking will allow more vehicles to queue on school property and reduce the use of Can -Dots Avenue for loading. Figure 8 shows the available queueing capacity around the school. Within the parking lot, up to 27 vehicles can queue while cropping -off or picking -up students. Additional queuing is available along Lincoln Street east of the parking lot along the curb for 19 additional. Along Can-Dota Avenue, additional storage is available with the elimination of existing access drives up to 15 vehicles. Currently, vehicles are queued from the Lincoln Street drop east to Can Dot Avenue and north on Can Dota Avenue to Milburn Avenue, approximately 1,200 feet. The new on -site loading area can accommodate 540 feet of storage significantly reducing on -street queuing. School Bus and Delivery Traffic The new driveway on Can -Dots Avenue will be limited in use to a few staff vehicles, school buses, and school deliveries. There are twelve parking spaces available to staff on the north side of the building. They would generate 12 inbound and 12 outbound trips outside of the peak arrival and dismissal times. School buses will use the drive twice a day to enter the school lot to drop-off or pick-up students. Deliveries will occur a couple of times a day by trucks of varying sizes providing school supplies, cafeteria supplies, refuse pick-up, and occasional maintenance deliveries.

Prospect, Illinois. The following recommendations were developed: 1. The projected student population is expected to decrease from 783 existing students to 730 students in the future. School related traffic volumes are expected to decrease. 2. During the morning and afternoon peak periods of school traffic, peak activity for approximately 20 minutes. 3. The proposed circulation plan is changing with the development of the new school. a. The three driveways on Can-Dota Avenue will be reduced to one drive restricted to staff, school bus, and delivery traffic. The conflicting traffic movements from the three original driveways will be significantly reduced. b. The west side of Can-Dota Avenue will still be used for some loading activity for up to 15 vehicles at a time. c. The small loading area on Lincoln Street will be replaced by a large parking lot with a loading area that accommodate 27 vehicles queueing on -site. d. Additional queueing is available on Lincoln Street in the parking lane for 19 vehicles. e. The school drive on Can-Dota Avenue will be restricted to school staff, school buses , and deliveries. 4. A new parking lot on the south side of the school along with a small lot on the northside of the school will accommodate the day-to-day parking needs without using on -street parking. 5. The proposed parking supply for the school is 114 parking spaces that exceeds the 99-space zoning requirement, the ITE estimate of 74 vehicles, and the surveyed demand of 82 parked vehicles. 6. Five accessible spaces are provided and meet the ADA code requirements.

Prospect. The existing 12.14 (±) acre site is bounded by residential properties to the north, west, and southwest, Lincoln St to the south, and Can-Dota Ave to the east. 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 middle school and associated improvements, including standalone garage maintenance building and surface parking lot. Various additions have been constructed to the original school facility. There is some notable elevation change across the site in existing conditions, and adjacent properties generally drain towards the school property. Additionally, much of the adjacent public ROW elevations are also higher than existing site elevations. In general, stormwater overflow routes from the site and Village storm sewer and adjacent properties convey to the north through neighboring parcels. There is notable Village utility infrastructure on the school property, which includes sanitary overflow chambers and lift station infrastructure, as well as well 30" diameter public storm sewer. There are notable portions of green space in existing conditions, particularly along the northern and western property line. There are no existing stormwater management facilities on -site, as none of the improvements on the campus to date have triggered the need for detention nor volume control improvements per Village nor MWRD requirements. The primary overflow route for the site is via the existing Village storm sewer that traverses the property. This storm sewer is not appropriately sized to convey the flow of the existing tributary area. In existing conditions , in any event where the sewer cannot convey the flows, the overland overflow route is to the north via the neighboring properties and towards the Milburn Ave ROW to the north. A secondary spill point is available via a neighboring parcel to the south towards Lincoln St ROW, but this is approximately 1' higher than the spill towards Millburn Ave. Sanitary flows are generally conveyed to the south towards the Village of Mt. Prospect combined sewer infrastructure in Na Wa Ta Ave. Notable portions of the existing building are also tributary to sanitary sewer improvements located in Can-Dota Ave. Record drawings confirm that the entirety of the 1967 building addition, which included gymnasium and locker improvements, are tributary to the sanitary sewer in Can-Dota Ave, and ultimately the Village sanitary overflow infrastructure. PROPOSED CONDITIONS The proposed project consists of the demolition of the existing school facility and associated improvements and construction of a new middle school facility. To meet the unique phasing and site constraints, the proposed building will be constructed while the existing school building is operational. Following the construction of the new school building, the existing school will be demolished, and the remainder of the site improvements will be constructed, including parking lot, pedestrian, and athletic improvements. The Contractor is responsible for all temporary phasing and construction means and methods required to safely accommodate the improvements. The proposed stormwater management facilities, as discussed later in this report, will be constructed in the initial phases of construction and will be available to provide storage for both the existing and proposed site improvements until appropriate to disconnect/connect these facilities. Since there are no stormwater management facilities present in existing conditions, installing the required below grade system in the early stages of the project will have a notable watershed benefit when compared to existing conditions. The proposed improvements will result in approximately 9.07 Acres of Qualified Development Area. Stormwater improvements are to be provided for all areas that are disturbed and are not able to be considered Non -Qualified Development. Areas excluded from the qualified development area include the western portion of the site, in the vicinity of Village utility infrastructure, where no work will be performed. A portion of the Village storm sewer that traverse the site is also to be relocated to provide additional separation from the building improvements, without impacting drainage patterns. As such, the sewer trench improvements are the only portions of the site that will be disturbed and is not accounted for in the Qualified Development Areas. These improvements are reasonably considered open space or maintenance activities and thereby excluded. The stormwater requirements, including both rate control (detention) and volume control storage, are to be provided in a below grade StormTrap 7'-0" Pre -Cast Vault system. Stormwater discharge will be conveyed to the Village of Mt. Prospect separate 30" storm sewer that traverses the property and outfalls to Weller Creek. The Village sewer is to be relocated in order to provide additional separation from the school improvements. The below -grade storage system is sized to mee the 100-Year, 24-Hour rain event in accordance with MWRD requirements. A new outlet control structure will be constructed on -site to appropriately control release rate. All Qualified Development Areas are in accordance with MWRD requirements, and appropriately exclude any improvements that can be considered Open Space Development or Non -Disturbed Areas. The emergency overland overflow route will continue to flow through the neighboring parcels to the north, without any changes to the overflow route or spill location from existing conditions. The improvements will slightly increase the tributary area and as such, peak overflow rate, tributary to this overflow location in the final conditions. However, the vast majority of the tributary area to this overflow will now first be tributary to the stormwater management system, meaning a significant reduction in peak runoff to village sewers and ultimately the adjacent parcel. Analysis is also included that shows the worst case scenario in terms of tributary area to the Village sewer and resulting overflow in the proposed conditions. To accommodate the additional flow, the HWL of the overflow would need to increase by about 0.04' from the existing conditions. This is believed to be negligible given that this would only occur in the event that the 100-year critical duration event occurred after the major stormwater management system had already been filled with a 100-year event. METHODOLOGY In order to determine the detention requirements on site, the MWRD Bulletin 75 Nomograph was used. The allowable release rate for the site was determined by looking at the Qualified Development Area (9.07 Acres). The site falls within the Des Plaines River watershed, with an assigned allowable release rate of 0.20 cfs/acre, resulting in a total allowable release rate of 1.81 cfs for the site. Per the results of the Nomograph utilizing the Reduced Curve Number, the required detention storage in the final conditions is 3.423 acre-ft. The required storage is to be provided in a 7'-0" tall concrete vault system located to the north of the new school building. The designed HWL of the system is the top of the interior of the vault, or 667.50. At this elevation, approximately 3.49 acre-ft of detention storage is provided. 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 StormTrap system. The storage beneath the outlet pipe is to be drained down via a 4" underdrain located on the perimeter of the system. Calculations for the StormTrap system following MWRD methodology is included in this report. This includes a 50% multiplier for all storage provided above the invert of the underdrain of the system, which is to be set at the invert of the vault. The primary overflow route for the site is via the existing Village storm sewer. This storm sewer is not appropriately sized to convey the flow of the tributary area per current rainfall events. In existing and proposed conditions, in any event where the sewer cannot convey the flows, the overland overflow route is to the north via the neighboring properties and towards the Milburn Ave ROW to the north. A secondary spill point is available via a neighboring parcel to the south towards Lincoln St ROW, but this is approximately 1' higher than the spill towards Millburn Ave. All site storm sewers are sized to convey the 100-year flows to the stormwater management system. Storm sewer sizing calculations are included in this report. SUMMARY Stormwater management improvements are in accordance with applicable MWRD and Village requirements. The project will result in a slight increase to tributary as well as impervious to the Village storm sewer and corresponding overflow to the neighboring property towards Millburn Ave, but will also provide a substantial watershed benefit by the inclusion of a significant below grade stormwater management system. This system and supporting improvements will significantly reduce peak runoff rates, volume, as well as frequency of events that utilize the overland overflow route due to the presence of the stormwater system sized for the 100-year requirements. As such, the project as a whole will have substantial watershed benefits when compared to the existing conditions, largely due to the increase in detained areas both on -site and from the adjacent properties. Sanitary flows will continue to be primarily conveyed to the south. Existing public sewer elevations prohibit the entirety of the building from draining to the existing sewer to the south of the site without introducing a lift station and pump infrastructure. As such, portions of the building are to be routed to the existing Village sanitary sewer to the west of the building, as the deeper elevation readily allows for a gravity only connection. Overall, the improvements will not result in an increase in students or staff, and will result in a decrease in water demand and resulting sanitary flows due to the incorporation of more efficient appliances. While the proposed conditions result in slight changes to existing sanitary flow patterns, EEA believes that overall the project will be a net positive for local sanitary infrastructure and also avoids the need for additional pump infrastructure, which are always a source of ongoing maintenance concerns.

Slab -on -grade construction; no partial or full -depth basement. • Storm Structure ■ Located underground in the southwestern portion of the new facility • New Parkina Area ■ Located south of the new school facility. ■ 99 parking stalls; approximately 85,760 square feet. 15, ■ Asphaltic cement concrete. • New Athletic Field, Running Track and Basketball Course ■ Located east of the new school building. 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. Subsurface exploration and geotechnical engineering analyses is desired to assess subgrade soil suitability and groundwater occurrence for the proposed school facility improvements. A total of 19 geotechnical soil borings S-1 through S-12 and C-1 through C-7 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 Friday, March 7, and Saturday, March 8, 2025 and a total of 19 geotechnical soil borings (labeled S-1 through S-12 and C-1 through C-7; Figure 1) were each drilled to 10 to 25 feet below existing surface grade (Table 1; Appendix A). The geotechnical drilling was performed mainly within pavements, grass lawn areas, and athletic fields situated near existing buildings and west of the existing school facility (Figure 1). There were no Site access issues encountered for the drilling rigs and the personnel who operated this equipment. Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 3 of 29 A summary of the findings from the subsurface exploration consists of the following: • Approximately 7 to 18 inches of maintained grass and topsoil was encountered at the ground surface at ten borings. Approximately 5 to 11 inches of asphalt pavement underlain by 7 to 18 inches of aggregate basecourse was encountered at six of the boring locations. Boring S-8 was performed in the baseball field and extended through the playing surface. • At 14 of the borings, interpreted, predominantly cohesive fill and possible fill soils extend between approximately 3.5-and-8.5 feet bgs for the soil borings advanced for this subsurface exploration, exhibited very soft to very stiff consistency, and the overall W, was calculated to range from 14.1 % to 29.1 %. Limited deposits of loose to medium dense sand and gravel fill was encountered in four of the borings, and exhibited standard penetration test N values in the range from 9 to 16 blows per foot. • In Borings C-2 and C-4, partly organic silty clay fill soils were encountered between depths of approximately 1 and 8.5 feet, with W, calculated to be in the range of 22.3% to 23.8%. • Interpreted native, undisturbed, oxidized cohesive and granular soils were intersected beneath fill soils and extend to depths ranging from approximately 8-to-13.5 feet bgs. • Native cohesive soils consisted of predominately silty clay and clayey silt, exhibited soft -hard overall average consistency, and overall W, was calculated to be in the range of 12.4% to 23.4%. • Within the predominant clay profile native oxidized granular soils were encountered in Borings S- 4, S-6 and C-1, consisted of predominantly poorly graded sand, exhibited loose to medium dense relative density, and overall average W, was calculated to be 10.0 to 15.6%. • Native oxidized, brown dominant -colored soils transitioned to unoxidized cohesive soils with distinct gray to pink -gray coloration at an average depth of approximately 10 feet bgs or an average elevation of approximately 654 feet AMSL. • Native unoxidized cohesive soils consisted of predominantly silty clay and clayey silt, exhibited soft -hard (typically firm -very stiff) overall average consistency. • Groundwater was observed during the drilling operation at eight (8) soil boring locations at a depth range of approximately 6-to-22 feet bgs with shallow groundwater (-7 feet or less bgs) occurring in no borings. • In three of the boreholes, static groundwater levels were measured within open boreholes at drilling completion with HSAs removed and ranged in depth from 9-to-22 feet bgs. • After the HSAs were removed, overall average DCI measured at each of the borings at depths of approximately 7 and 23.5 feet bgs (Appendix A). • 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 school building that will be slab -on -grade construction with no partial or full basements. • The aroaosed new school buildina will be constructed of a multi-story structure constructed of CMU block walls supported on a conventional shallow foundation system consisting of spread and/or continuous strip footings, extended through existing fill and lower strength natural soil (encountered in the borings to depths of 3'/2 to 8'/2 feet (Elevations 660 to 666.5 feet) below the existing_ ground surface), bearing on suitable, natural, stiff to hard silty clay and clayey silt, or Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 4 of 29 directly on lean concrete backfill that extends to these soils. For footings, bearing at depths of at least 3'/2 feet below grade on natural, stiff to hard silty clay and clayey silt, or directly on lean concrete backfill that extends to these soils, we recommend a maximum net allowable soils bearing pressure of 2,000 psf be used to proportion the footings. The proposed interior slabs -on -grade construction completed at -grade and full -depth removal of existing fill soils or lower strength native cohesive soils encountered in the soil borings to depths of at least 31/ to 8'/2 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 and lower strength native cohesive soils should be completely removed and replaced with new engineered fill to the depth encountered. PROJECT DESCRIPTION SET Consultants understands the redevelopment will entail renovation of existing Site buildings (Figure 1) and proposed new construction of the following structures: • Academic Wing ■ Three-story academic wing constructed in the central portion of the site. ■ Slab -on -grade construction; no partial or full -depth basement. • Classroom and Cafeteria Area ■ Two-story classroom and cafeteria structure and gymnasium to be located west of the academic wing. Slab -on -grade construction; no partial or full -depth basement. • Storm Structure ■ Located underground in the southwestern portion of the new facility • New Parkina Area ■ Located south of the new school facility. ■ 99 parking stalls; approximately 85,760 square feet. 15, ■ Asphaltic cement concrete. • New Athletic Field, Running Track and Basketball Course ■ Located east of the new school building. SCOPE OF WORK 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. Subsurface exploration and geotechnical engineering analyses is desired to assess subgrade soil suitability and groundwater occurrence for the proposed new building structures. Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 5 of 29 A total of 19 geotechnical soil borings (S-1 through S-12 and C-1 through C-7; Figure 1) were advanced using conventional rotary, hollow -stem auger (HSA) drilling along proposed new building exterior foundation wall alignments targeting building corners where accessible, and each soil boring was advanced to a maximum depth of 25 feet below existing surface grade. The soil boring label and associated building structure foundation position are as follows: • S-1 through S-12 — New School Structures. • C-1 through C-7 — New Parking Areas, Athletic Fields, and Running Track. Building design loads were not provided as of the date of this letter report. The findings and recommendations contained in this letter report are based on the geotechnical soil borings performed for this project and associated laboratory testing of soil samples. This letter report presents our recommendations for subgrade preparation and foundation design specific for the project. In addition, the letter report provides general construction considerations based on the results of the geotechnical soil borings and our previous experience. SITE PHYSICAL SETTING REVIEW This section discusses Site topography, mapped Site vicinity soils and surficial geology. Setting & Topography According to the Cook County GIS portal, the Site encompasses 13.5 acres and comprised of Property Index Numbers 08-11-215-011-0000, 08-11-214-037-0000, and 08-11-214-002-0000. The majority of the Site is improved with 1-story masonry school building, exterior pavement drive lanes and parking lots, and open areas in part occupied with athletic fields. The Site is presently bounded on the south by West Lincoln Street, on the west and north by single-family residences, and on the east by Can Dota Avenue. Site topography is mapped as relatively flat -lying with elevations ranging between approximately 664-and- 675 feet above mean sea level (AMSL) for the majority of the Site. There is a relatively higher elevation area immediately south of the existing school structure where surface elevation at Boring C-1 was observed at approximately 673 feet AMSL. Finished exterior grades at borings performed at other areas across the Site were in the range of elevation between approximately 668-and-671 feet AMSL. Historical mapping reveals the Site to be sloping down toward the southeast (USGS, 1962; 2021) with a minimum elevation of 670 feet AMSL. The school building in its current configuration does not appear on the previous version of the topographic map (USGS, 1953). Mapped Soils According to soil mapping efforts published by the United States Department of Agriculture (USDA), Markham-Ashkum-Beecher complex (Code 854B), 1 to 6 percent slopes (USDA, 2024) are situated across the entire site. Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 6 of 29 Markham-Ashkum-Beecher complex materials physical characteristics include ground moraines and end moraines landform settings; natural drainage class described as "Moderately Well drained"; and, the typical vertical soil profile consists of silty loam in the upper 8 inches underlain by silty clay loam from approximately 8 inches to 60 inches below surface grade. Markham-Ashkum-Beecher complex soils exhibit ground slopes ranging from 1-to-6%, medium runoff class, and negligible frequency of flooding or ponding (USDA, 2024). 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 Saturday, March 8, 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. SET Consultants 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, IL) 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 7m The soil boring locations were field -located and flagged by a SET Consultants field representative on Friday, March 7t" 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. The ESI field representative proceeded to field clear the 19 geotechnical soil borings (Figure 1). Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 7 of 29 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 depth of 25 feet bgs (borings S-1 through S-12 and C-1through C-7). 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 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. Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 8 of 29 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 7 and March 8, 2025. Site Physical Description The geotechnical drilling was performed mainly within open, maintained grass lawn 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 3 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 Friday, March 7th and Saturday, March 8`h by advancing a total of 19 geotechnical soil borings (labeled S-1 through S-12 and C-1 through C-7; Figure 1) at or close to proposed new building exterior foundation wall alignments. The soil borings were each drilled to depths of 10 to 25 feet below existing surface grade (Table 1; Appendix A) and amounted to 370 feet of total drilling footage. A summary of the findings from the subsurface exploration consist of the following: • Approximately 7 to 18 inches of maintained grass and topsoil was encountered at the ground surface at ten borings. Approximately 5 to 11 inches of asphalt pavement underlain by 7 to 18 inches of aggregate basecourse was encountered at six of the boring locations. Boring S-8 was performed in the baseball field and extended through the playing surface. • At 14 of the borings, interpreted, predominantly cohesive fill and possible fill soils extend between approximately 3.5-and-8.5 feet bgs for the soil borings advanced for this subsurface exploration, exhibited very soft to very stiff consistency, and the overall W, was calculated to range from 14.1 % to 29.1 %. Limited deposits of loose to medium dense sand and gravel fill was encountered in four of the borings, and exhibited standard penetration test N values in the range from 9 to 16 blows per foot. Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 9 of 29 • In Borings C-2 and C-4, partly organic silty clay fill soils were encountered between depths of approximately 1 and 8.5 feet, with Wc calculated to be in the range of 22.3% to 23.8%. • Interpreted native, undisturbed, oxidized cohesive and granular soils were intersected beneath fill soils and extend to depths ranging from approximately 8-to-13.5 feet bgs. • Native cohesive soils consisted of predominately silty clay and clayey silt, exhibited soft -hard overall average consistency, and overall W. was calculated to be in the range of 12.4% to 23.4%. • Within the predominant clay profile native oxidized granular soils were encountered in Borings S- 4, S-6 and C-1, consisted of predominantly poorly graded sand, exhibited loose to medium dense relative density, and overall average Wc was calculated to be 10.0 to 15.6%. • Native oxidized, brown dominant -colored soils transitioned to unoxidized cohesive soils with distinct gray to pink -gray coloration at an average depth of approximately 10 feet bgs or an average elevation of approximately 654 feet AMSL. • Native unoxidized cohesive soils consisted of predominantly silty clay and clayey silt, exhibited soft -hard (typically firm -very stiff) overall average consistency. • Groundwater was observed during the drilling operation at eight (8) soil boring locations at a depth range of approximately 6-to-22 feet bgs with shallow groundwater (-7 feet or less bgs) occurring in no borings. • In three of the boreholes, static groundwater levels were measured within open boreholes at drilling completion with HSAs removed and ranged in depth from 9-to-22 feet bgs. • After the HSAs were removed, overall average DCI measured at each of the borings at depths of approximately 7 and 23.5 feet bgs (Appendix A). • Bedrock was not encountered on -site from the soil borings completed for this subsurface exploration. Subgrade Soil Lithologies The soil types observed for this investigation were a surficial fill soil layer that graded to native, undisturbed, oxidized cohesive and granular soils overlying native unoxidized cohesive soils to drilling termination depth. Shallow water -bearing granular soils were intersected at 11 of the 12 soil borings, and groundwater was observed and static water levels measured during the drilling operation at 5 of the 11 soil boring locations. A description of these soil lithologies is as follows: Fill Soils A surficial, dark brown -brown clay -dominated "topsoil' layer was intersected borings with average thickness close to 7 to 18 inches at ten of the borings. Topsoil was absent at soil borings S-1 through S-4, C-2, and C-4 were drilled through 5 to 11-inch thick layers of asphaltic pavement underlain by an approximate 7 to 18-inch granular basecourse layer, At 14 of the borings, interpreted fill material was comprised of predominantly cohesive soils. Cohesive fill soils consisted of very soft to very stiff silty clay and lesser amounts of loose to medium dense sand and gravel was present and varying coloration to include dark brown, brown, light brown, and gray (Appendix A). Fill soils extended between approximately 2-and-4 feet bgs (Figures 2 & 3) and averaged close to 3 feet bgs for the soil borings advanced for this subsurface exploration. Cohesive fill exhibited Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 10 of 29 very soft -to -hard consistency range. Interpreted fill soils yielded overall average estimated Qp readings collected at time of SS sampling of <0.25 to 4.0 tsf that coincides with very stiff consistency, and the overall Wc values ranged from 14.1 to 29.1 %. Granular soils layers were loose to medium dense in relative density with standard penetration test N values ranging from 9 to 16 blows per foot. Native Oxidized Soils Interpreted native oxidized cohesive and granular soils were intersected below fill soils and extend to depths ranging from approximately 8.5-to-13.5 feet bgs encountered at and above the seasonal or long-term high groundwater elevation (Appendix A). Native Unoxidized Soils Unoxidized cohesive soils that are characterized by gray coloration were observed at the 15 soil borings completed for this project from at least 8.5-to-13.5 feet bgs or shallower and extend to drilling termination depth (Appendix A). Cohesive Soils — Representative cohesive soil lithologies encountered were dark brown, brown, and gray sandy and silty clay. Silt, silty clay, and clay with variable brown, light brown, and gray coloration were the dominant cohesive lithologies encountered for this subsurface exploration. Native cohesive soil consistency based on N-values and calibrated hand penetrometer tests recorded at the time of drilling ranged from soft to stiff to hard (0.5 to 4.5+ tsf) at the boring locations. W, ranged from 12.4% to 23.4%. Granular Soils — Representative granular soil lithologies encountered were poorly graded gray sand and gravel. Poorly graded sand, poorly graded sand or sand, with gravel were the dominant granular lithologies encountered for this subsurface exploration and intersected in the 3 of the 19 of the soil borings (Appendix A). Native granular soil consistency based on N-values recorded at the time of drilling ranged from loose to medium dense density (9-17 bpf) at S-4 (8.5-13.5 bpf), S-6 (19-23.5 bpf), and C-1 (6-8.5 feet bgs SS interval). 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 while drilling at soil borings S-1, S-4, S-6, S-8, S-12, C-3, and C-4 at a depth range of approximately 6 feet bgs (C-4) to approximately 22 feet bgs (S-1). Static groundwater levels were measured within soil borings S-6, S-8, and S-11 open boreholes at drilling completion with HSAs removed and ranged in depth from 9-to-22 feet bgs (Table 1; Appendix A). Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 11 of 29 After the HSAs were removed, overall average DCI measured at six (6) of the borings at depths of approximately 13 and 15 feet bgs. DCI was recorded at the nine (9) soil borings at depths of approximately 7 to 23.5 feet bgs (Appendix A). 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 the soil borings and interpreted to range from approximately 8.5 feet bgs (six borings) to approximately 13.5 feet bgs (S-3, S-7, and S-12) at most other borings and at typical depths in the range of 10 feet bgs. The elevation range for the interpreted long-term groundwater level is approximately 653 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. SET also calculated the spectral response factors based on the site class as well as the latitude and longitude of the project location using United States Geological Survey (USGS) seismic calculator software. The calculated values are presented in the table below.

If there are any changes to the project characteristics, objectives, or if different subsurface conditions are Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 12 of 29 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 SET Consultants understands the redevelopment will entail renovation of the existing Site building (Figure 1) and proposed new construction of the following structures: proposed new construction of the following building structures: • Academic Win ■ Three-story academic wing constructed in the central portion of the site. ■ Slab -on -grade construction; no partial or full -depth basement. • Classroom and Cafeteria Area ■ Two-story classroom and cafeteria structure and gymnasium to be located west of the academic wing. ■ Slab -on -grade construction; no partial or full -depth basement. • Storm Structure ■ Located underground in the southwestern portion of the new facility. • New Parking Area ■ Located south of the new school facility. ■ 99 parking stalls; approximately 85,760 square feet. 15, ■ Asphaltic cement concrete. • New Athletic Field, Running Track and Basketball Course ■ Located east of the new school building. SCOPE OF WORK 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. Subsurface exploration and geotechnical engineering analyses is desired to assess subgrade soil suitability and groundwater occurrence for the proposed new building structures. SET Consultants conducted subsurface exploration activities on Friday, March 7th and Saturday, March 8rh by advancing a total of 19 geotechnical soil borings (labeled B-1 through B-19; Figure 1) at or close to proposed new building exterior foundation wall alignments, within new pavement areas, and athletic field improvements. The soil borings were each drilled to depths of 10 to 25 feet below existing surface grade (Table 1; Appendix A) and amounted to 370 feet of total drilling footage. A summary of the findings from the subsurface exploration consist of the following: • Approximately 7 to 18 inches of maintained grass and topsoil was encountered at the ground surface at ten borings. Approximately 5 to 11 inches of asphalt pavement underlain by 7 to 18 inches of aggregate basecourse was encountered at six of the boring locations. Boring S-8 was performed in the baseball field and extended through the playing surface. • At 14 of the borings, interpreted, predominantly cohesive fill and possible fill soils extend between approximately 3.5-and-8.5 feet bgs for the soil borings advanced for this subsurface exploration, exhibited very soft to very stiff consistency, and the overall W,, was calculated to Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 13 of 29 range from 14.1 % to 29.1 %. Limited deposits of loose to medium dense sand and gravel fill was encountered in four of the borings, and exhibited standard penetration test N values in the range from 9 to 16 blows per foot. • In Borings C-2 and C-4, partly organic silty clay fill soils were encountered between depths of approximately 1 and 8.5 feet, with W, calculated to be in the range of 22.3% to 23.8%. • Interpreted native, undisturbed, oxidized cohesive and granular soils were intersected beneath fill soils and extend to depths ranging from approximately 8-to-13.5 feet bgs. • Native cohesive soils consisted of predominately silty clay and clayey silt, exhibited soft -hard overall average consistency, and overall W, was calculated to be in the range of 12.4% to 23.4%. • Within the predominant clay profile native oxidized granular soils were encountered in Borings S- 4, S-6 and C-1, consisted of predominantly poorly graded sand, exhibited loose to medium dense relative density, and overall average W, was calculated to be 10.0 to 15.6%. • Native oxidized, brown dominant -colored soils transitioned to unoxidized cohesive soils with distinct gray to pink -gray coloration at an average depth of approximately 10 feet bgs or an average elevation of approximately 654 feet AMSL. • Native unoxidized cohesive soils consisted of predominantly silty clay and clayey silt, exhibited soft -hard (typically firm -very stiff) overall average consistency. • Groundwater was observed during the drilling operation at eight (8) soil boring locations at a depth range of approximately 6-to-22 feet bgs with shallow groundwater (-7 feet or less bgs) occurring in no borings. • In three of the boreholes, static groundwater levels were measured within open boreholes at drilling completion with HSAs removed and ranged in depth from 9-to-22 feet bgs. • After the HSAs were removed, overall average DCI measured at each of the borings at depths of approximately 7 and 23.5 feet bgs (Appendix A). • 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 and the previous exploration performed at the site, SET Consultants recommends the following for the proposed new multi -story school improvements that will be slab -on - grade construction with no partial or full basements. • The proposed new school building will be constructed of a multi -story structure constructed of CMU block walls supported on a conventional shallow foundation system consisting of spread and/or continuous strip footings, extended through existing fill and lower strength natural soil (encountered in the borings to depths of 3'/2 to 8'/2 feet (Elevations 660 to 666.5 feet) below the existing ground surface), bearing on suitable, natural, stiff to hard silty clay and clayey silt, or directly on lean concrete backfill that extends to these soils. For footings, bearing at depths of at least 3'/2 feet below grade on natural, stiff to hard silty clay and clayey silt, or directly on lean concrete backfill that extends to these soils, we recommend a maximum net allowable soils bearing pressure of 2,000 psf be used to proportion the footings. • The proposed interior slabs -on -grade construction completed at -grade and full -depth removal of existing fill soils or lower strength native cohesive soils encountered in the soil borings to depths of at least 3'/2 to 8'/2 feet or greater below existing surface grade and replacement with new Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 14 of 29 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 and lower strength native cohesive soils should be completely removed and replaced with new engineered fill to the depth encountered. Based on these geotechnical findings for the proposed new structures, suitable soils are anticipated at the design footing bottom subgrade elevation or within approximately 3'h to 8'h feet of the design elevation. Where unsuitable soils may be exposed, the footing excavations shall be deepened to reach suitable soils (at approximate elevations of 660 to 667 feet AMSL in the borings). It should be emphasized the should foundation excavation deepening be required, it is not permissible to backfill these excavations with new fill due to the increased potential for additional settlement. Rather, the footings should bear directly at that lower level or the excavations should be backfilled with a lean concrete mix back to the design elevation. Groundwater Occurrence Site topography is generally flat -lying, ranges between approximately 668-and-673 feet AMSL. Groundwater occurrence was observed in 7 borings during drilling at depths of approximately 6 to 22 feet and at 3 borings post drilling water levels were located at depths of approximately 9-to-22 feet below grade. This suggests that groundwater in this stratum is likely localized and perched, but could be more substantial after rain events. 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. Sub -grade Preparation This section discusses subgrade preparation activities to include initial Site preparation, underground utilities, proofrolling, and compaction. We understand the proposed new school facility improvements will constructed adjacent to the existing school building. Based on historical information reviewed for this letter report, the present-day Site building configuration appears to have remained unchanged since the late 1950s or early 1960s. Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 15 of 29 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 and parking lot footprints after existing Site building demolition. Stripping limits should extend to a minimum of 10 feet beyond the limit of the new school building footprint and a minimum of 5 feet beyond the edge of exterior pavements and flatwork. Unsuitable materials, such as 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. The sides of the excavations should be sloped or braced for stability. Care should be taken to not undermine the foundations of the existing building during excavation. Shoring, sheeting, or bracing of the sides of the excavations may also be required to avoid undermining the existing foundations. 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. 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. Demolition/Utilities — Existing utilities should be abandoned and relocated, and associated structures and backfill materials should be removed from proposed building areas unless they are planned to remain in service for the new school improvements. Prior to construction, we recommend all utilities in the proposed construction areas be positively identified and marked. 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 areas 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. Floor slabs and below grade foundation elements of the existing buildings should be completely removed where they will conflict with new construction. The tops of foundation walls should be removed to depths of at least 2 feet below the base of new pavements, but existing wall backfill materials, if encountered, should be completely removed and replaced with controlled compacted fill. Soils exposed in the excavations created by the demolition should be observed and evaluated by an experienced geotechnical technician or engineer. The completed excavations should be backfilled with properly placed and compacted fill as recommended in this report. Improper placement and compaction of fill materials during demolition/removal of existing Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 16 of 29 foundations and other structures could lead to inconsistent subgrade performance resulting in foundation, floor slab and pavement distress and settlement. It has been our experience that many demolition contractors place the debris from the structure below grade and cap with soil. These type of activities will not provide a suitable subgrade for new foundations, slabs or pavements. Costs of removal and replacement of demolition debris could unnecessarily add thousands of additional dollars to the cost of the project. The presence of a SET geotechnical engineer on the site during demolition and backfilling operations would reduce the potential for unnecessary removal and replacement to take place during construction. We do not recommend the use of 3-inch stone or "Pea Gravel" as engineered fill to backfill undercuts, particularly under floor slabs, pavements and foundations. Due to the large diameter and/or absence of fines, the 3-inch rock exhibits large voids. Fill materials containing large voids are more susceptible to future movement that may become unstable resulting in excessive and variable settlement. Current EPA and State law requires an asbestos survey prior to demolition or renovation activities. In the event regulated asbestos materials are confirmed to be present, any regulated asbestos materials that would be disturbed must be removed prior to such disturbance by a licensed asbestos removal firm. 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 and parking lots. 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 vehicle weight of at least 10 tons may be used at this time to aid in identifying localized soft/loose or unsuitable material which should be removed. Any soft/loose or Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 17 of 29 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 — The Site has a development history with the original Site building constructed during the late 1950s or early 1960s. 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. 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 3.5 to 8.5 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 steel, 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 school building pad area. 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 on-site/off-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 Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 18 of 29 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 footprint areas and should be compacted with a sheepsfoot roller. Granular engineered fill should be compacted with a steel, 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. Footing Foundations Based on the project information along with field and laboratory test data collected for this investigation, SET Consultants recommends the proposed new multi -story school building can be supported on a conventional shallow foundation system consisting of spread and/or continuous strip footings, extended through existing fill soil and lower strength clay soils (encountered in the borings to depths of 3'/2 to 8'/2 feet (Elevations 660 to 667 feet AMSL) below the existing ground surface), bearing on suitable, natural, stiff to hard silty clay and clayey silt, or on new engineered fill. For footings, bearing at depths of at least 3'/2 feet below grade on natural, stiff to hard silty clay and clayey silt, or on new engineered fill, we recommend a maximum net allowable soils bearing pressure of 2,000 psf be used to proportion the footings. It is recommended that the freshly exposed subgrade soil at design footing bottom elevation be evaluated and soil bearing strength trength field -verified under the observations of an experienced geotechnical engineer and/or soils technician. If field soil bearing strength readingsying a 2,000 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 school building 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 Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 19 of 29 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. 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 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'/2 and 8'/2 feet 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 office building. 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 lavers of exiting fill soils and anticipated to extend to natural, stiff to hard silty clay and clayey silt at depths of about 3'/2 to 8'/2 feet 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. Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 20 of 29 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. 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. Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 21 of 29 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. 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 (31/ 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) f = 0.35 Concrete Over Granular Material (Sand) f = 0.55 *These Values do Not Reflect a Factor of Safety Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 22 of 29 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 structures are assumed to be interior slab -on -grade construction completed at -.grade and full -depth removal of existing fill soils or lower strength native cohesive soils encountered in the soil borings to depths of at least 3'/2 to 8'/2 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 and lower strength native cohesive 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 3.5 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. Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 23 of 29 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 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%2 to 8'/2 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. Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 24 of 29 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. 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. Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 25 of 29 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 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'/2 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 and parking lot 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 should be prepared to extend shallow foundations to greater depths at isolated locations. Excavations - We recommend that excavations of the proposed new building and parking lot 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 structure 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 Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 26 of 29 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 building 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. However, due to the persistence of granular soils encountered generally within depths of 13'/2 and 20 feet in the borings, seepage might be more substantial after rain events, but would likely dissipate with time. If groundwater is encountered, we believe a 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. 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 Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W. Lincoln Street, Mount Prospect, IL SET Project No. 2136_1 April 7, 2025 Page 28 of 29 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. Subsurface Exploration and Geotechnical Engineering Analyses New Lincoln Middle School 700 W.

The site is currently occupied by Lincoln Middle School that was originally constructed in 1953. Permit records show that the school has since undergone multiple additions, and a maintenance building was constructed in 1962. According to the traffic impact study, the Lincoln Middle School currently serves 783 students in grades 6 through 8 with 91 staff members. Over the next six years, the student population is expected to decrease by 53 students to 730 students (-6.7%). In November 2024, residents approved an $85 million referendum to address critical needs within the school district. According to the petitioner, these needs include the replacement of the existing middle school, which has struggled with outdated classrooms, limited space, and aging infrastructure. The proposed newfacility is intended to provide a modern, accessible environment designed to support innovative instruction and meet the educational needs of today's students. PROPOSAL The petitioner, STR Partners LLC, on behalf of the Mount Prospect School District 57 (D57), proposes to construct a new 127,000 square foot replacement middle school, demolish the existing building, and complete related site improvements. The new school includes a three-story academic wing including the students' core classrooms, a two-story administration area, a learning resource center, experience classrooms, a storm shelter, gym, cafetorium, maintenance and support areas, and an outdoor learning/gathering space. Construction of the new facility is anticipated to begin in the fall of 2025, with completion targeted for August of 2027. The new school will be built while the existing school remains operational, with both structures coexisting on the site until the summer of 2027. Construction will run concurrently with the existing school until the summer of 2027. Demolition of the existing main school building and final site work are planned for completion by the summer of 2027. Conditional use approval is required as two principal structures will be present on the property during the transition period. The petitioner also requests relief from Sections 15.401(B) and 15.402(B) which require stormwater detention to be provided forthe entire site when a new building is constructed. Site Plan: The new school is strategically sited with its tallest massing element —the nearly 50-foot- tall (48'-0"), 3-story academic wing— positioned at the center of the school property to minimize impacts on the adjacent residential properties. The building's massing is designed to step down appropriately to align with the scale of the surrounding neighborhood. A new, expanded parking lot with a queuing lane dedicated for parent drop-off/pick-up is proposed along Lincoln Street. Separate access for buses and delivery vehicles is provided north of the academic wing, within the outdoor play area. A continuous fire lane is provided around the new building and fire hydrants are distributed around the school to ensure adequate fire protection. The development also provides underground stormwater volume control and detention storage north of the school. Open green space will be preserved along the west and north portions of the site for use by physical education classes. A discus cage is located at the northeast corner of the subject property. Following the demolition of the existing school and associated parking areas, a 200-meter track and new athletic field will be constructed along the east side and southeast corner of the site and will offer accessible recreational amenities to the community during non -school hours. HAPLAMPlanning & Zoning COMM\P&Z 2025\Staff Reports\PZ-07-25, PZ-10-25 700 W Lincoln St (Final PUD, Final Plat of Subdivision).docx.docx Traffic and Parking: The Village requires schools serving grades K through 8 to provide one parking space per employee, plus eight visitor spaces. Based on the staffing level of 91 employees, the school is required to provide 99 parking spaces. The current parking lot provides a total of 77 parking spaces. The proposed site plan includes a total of 106 parking spaces, exceedingthe Village's requirement and representing a net increase of 29 parking spaces compared to the current condition. The additional parking will significantly improve overall site functionality and better accommodate daily operations and visitors. According to the Petitioner's project description, long-term staff parking will be located in the large south parking lot, while visitor parking will be designated in the smaller southwest lot for ease of access. The north lot will be used exclusively for bus drop-offs and pick-ups, with no long-term bus parking on site. An additional 9 parking spaces at the northeast corner of the building will be reserved for maintenance and food service personnel. Building Elevations: The proposed building elevations feature a contemporary institutional design, characterized by clean lines, a mix of durable materials, and articulated massing. The exterior incorporates brick masonry, fiber cement panels with a wood -like appearance, aluminum storefront systems, and aluminum -composite metal paneling, which provide visual interest and durability. The facades are articulated through changes in plane, material transitions, and patterns to help break up the overall massing. The color palette consists of warm, neutral tones. Rooflines are varied in height, while all rooftop mechanical units will be screened from view. Additionally, ground -mounted mechanicaVutility equipment, as well as the trash enclosure, will be screened with brick masonry walls. The gradual stepping down of taller building elements to shorter elements, organized according to the function of the spaces, is appropriately scaled to the surrounding single-family residential neighborhood, resulting in contextually sensitive massing and a pedestrian -friendly scale. Landscaping: The existing landscaping will remain along the north, west and south property lines and additional canopy trees have been added along the west property line. Perimeter landscaping, consisting of a variety of existing deciduous trees, new canopy trees, and a combination of deciduous and evergreen shrubs, will be provided along the south property line. A considerable amount of foundation landscaping will also be provided along portions of the building's north, south and east facades. The petitioner is requesting relief from strict conformance of the foundation and perimeter Landscaping requirements. Foundation landscaping will not be provided along most of the north and the entirety of the west elevations since these facades face private property. While a 6-foot-tall screen/buffer is required along the length of the rear and interior side yards, a shorter screen/buffer will be provided only in select areas at the southwest and northeast corners of the property, in response to requests from specific adjacent property owners (see section of staff report titled "Resident Concerns"). This approach also helps preserve the openness and accessibility of the school's open spaces, which are valued by neighboring residents. Additional trees have been added to the northeast as well as providing additional landscape screening around the discus cage. Relief is also requested from the requirement to provide an even 50/50 distribution of deciduous shrubs and evergreen shrubs. The petitioner requests a mix of 70/30 mix of deciduous to evergreen shrubs due to the number of plantings proposed and their proximity to pavement areas that will be subject to de-icing agents, as these conditions are not conducive to healthy evergreens. Lastly, relief is requested from the requirement to provide planting islands that are 120 square feet in area in the southwest parking lot, and to provide planting islands for every seventeen (17) parking spaces in a parking row in the south parking lot to maximize the number of parking stalls and facilitate snow HAPLAMPlanning&Zoning COMM\P&Z202S%Staff Reports\PZ-07-25, PZ-90-25700 W Lincoln St (Final PUD, Final Plat of Subdivision),domdocx removal. In place of the three (3) planting islands in the south parking lot, a striped pedestrian pathway will be provided to allow safe access through the lot. Lighting: The petitioner provided the photometric plan for the existing site. The petitioner is proposing nineteen (19) light poles that illuminate the drive aisles, parking lots and fire lane, twenty-one (21) exterior wall -mounted light fixtures on the fagades of the new building, and four (4) uplights around the monument sign along Lincoln Street. A fully compliant photometric plan will be required as part of the building permit submittal. Signage: The petitioner intends to install one wall -mounted sign and one canopy sign on the south elevation facing Lincoln Street. A new monument sign is also proposed just west of the Lincoln Street driveway and a freestanding sign is proposed along the Can Data Avenue frontage just east of the track & field. Per the petitioner, relief is requested for: items of information as Lincoln Middle School is a very common school name in Illinois, while the proposed monument sign will include the full district name for identification, and the sign copy contains 12 items of information exceeding the 10 items permitted by code; orientation for the freestanding sign at the track & field (honorary naming will be visible from both sides and parallel with the long jump to best utilize the limited green space and maintain student safety); and sign surface area for the canopy sign (18.5 square feet) which exceeds the 4 square feet permitted for secondary signage. Any future relief requested for signage shall require an application for a minor amendment to the PUD. Phasing: The project is estimated to begin in October of 2025, and the existing school building, south side drop-off lane, and the east side drive and parking area will remain active during construction. The new school building is anticipated to start in October of 2025 and will be completed by May of 2027. The new below -grade detention system will be installed during the summer of 2026. The demolition of the central and southern portions of the school will commence in May/June of 2027. All building demolition will be completed by August of 2027. The new south side parking lot will begin once the central and southern portions of the existing school have been demolished. The new south parking lot will be completed in August of 2027. The new east side bus drive/loop and paved areas will commence mid- to late -summer of 2027 and will be completed in the fall of 2027. The east side of the track and green space will commence after the demolition of the existing school and will continue through the fall of 2027. A phasing schedule including diagrams are included with this staff report. Other Departments: The Public Works department expressed concerns related to turning movements from the school's new driveway onto Can Dota Avenue. The short 75-foot offset between West Milburn Avenue and the proposed driveway may potentially lead to collisions between a bus and another vehicle performing simultaneous left turns. When making a leftturn onto Can Dota Avenue, stopping distances may be insufficient to avoid collisions if vehicles turn simultaneously. At 15 mph, passenger vehicles require about 80 feet to stop, increasingto 115 feet at 20 mph; buses require even longer distances. This limited space increases the risk of conflicts. Because of this safety concern, Public Works remains committed to prohibiting left turns out onto Can Dota Avenue. Staff recommends that the Left turn restriction be included as a condition forthe Planning and Zoning Commission's recommendation to the Village Board. Building & Inspection Services and the Fire Department did not have any conditions of approval for the zoning request. The departments each provided comments on items to be provided at the time of building permit submittal. These comments can be found in the Village review letter dated July 27, 2025 (PZ-07-25). HAPLAMPlanning & Zoning COMM\P&Z 20251Staff Reports\PZ-07-25, PZ-10-25 700 W Lincoln St (Final PUD, Final Pint of Subdivision).docx.docx Plat of Subdivision (Consolidation and Vacation) The subject property encompasses five parcels and four parcel identification numbers (PINs): • Parcel 1: 08-11-214-037-0000; • Parcel 2: 08-11-214-002-0000; • Parcel3: 08-11-215-011-0000; and • Parcel 4: 08-11-214-036-0000 • Parcel 5 does not appear to have an assigned PIN. Afin al plat to consolidate the lots into a single lot is required so that the application of setbacks and other bulk regulations is straightforward. The plat shows that the southern half of the vacated portion of Milburn Avenue west of Can Dota Avenue is included as part of the school district property. Additional right-of-way along the Lincoln Street frontage will be dedicated to the Village, allowing a consistent right-of-way width across the Lincoln Street frontage, and allows the existing public sidewalk to be located on public property. This new dedication also causes the existing monument sign to be in the public right-of-way and the project will be conditioned to allow the monument sign to remain until such time the sign is relocated onto school property. While the proposed development meets the Village's 25-foot building setback requirements, the warranty deed affecting the southwest portion of the property imposes a more restrictive 50-foot setback. Although the current proposal does not encroach into the required zoning setbacks, the petitioner is revising the plans to conform to the 50-foot warranty deed restriction, doubling the setback otherwise required by the zoning code. The school district will provide the modified plans in advance of the Village Board meeting. Resident Concerns: The Petitioner has provided regular project updates through meetings and the school website to maintain an open dialogue with the surrounding community. Specific comments include: • The property owner at 806 West Lincoln Street (Lot 25) would like to preserve as much green space as possible along the property owner's east property line and requested the planting of evergreen shrubs no taller than 3 to 4 feet. The property owner specifically requested that no trees be planted along the east property line, as they would obstruct sunlight to the property and to the existing greenhouse on the owner's property. • The property owner at 220 Can Dota Avenue expressed concerns regarding privacy, the condition of existing trees along the perimeter of their property, and the visibility and activity surrounding the discus cage. In response, the property owner has requested the installation of fencing and additional landscaping to provide screening. The property owner has also requested that District 57 reach out to ComEd to explore the potential for replacing certain utility poles. • The property owner at 305 Can Dota Avenue raised several concerns, including the alignment of the proposed school driveway in relation to their own driveway, the continuation of parking restrictions during school hours on the 300 block of Can Dota Avenue, and whether modifications to the drop-off and pick-up procedures will be implemented for the 2025 school year. The property owner has also requested clear and timely communication goingforward regarding project milestones. HAPLAMPIanning & Zoning COMM\P&Z 2025\Statt Raports\PZ-07-25, PZ-10-25 700 W Lincoln St (Final PUD, Final Plat of Subdivision),docx.docx Aside from these three properties, no additional concerns have been expressed by neighboring residents regarding the proposed school redevelopment as of the writing of this report. Feedback from neighboring property owners was taken into consideration, and the plans are being finalized accordingly to address these concerns. STORMWATER DETENTION AND DEVELOPMENT CODE EXCEPTION Sections 15.401(B) and 15.402(B) of the Village Code require that stormwater detention be provided for the entire site when a new building is constructed. The Engineering Division indicated that it would seem appropriate that the easement area over the Village's sanitary overflow system located at the west end of the site be exempted from counting towards the entire site. Any area to be exempted would require a variation from the Village Code granted by the Village Board, and Schedule L to be included in the MWRD permit application. The Engineering Division reviewed the request and supports the requests. Development Code Exception Standards Section 15.109 permits the Planning & Zoning Commission to recommend approval of exception to the development code regulations in cases of 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 request must meet the standards for an exception, which are listed in Section 15.109 and are summarized as follows: • A hardship due to the physical surroundings, shape, or topographical conditions of a specific property not generally applicable to other properties in the same zoning district and not created by any person presently having an interest in the property; • Lack of desire to increase financial gain; and • Protection of the public welfare, other property, and neighborhood character. Per the petitioner, the site contains significant existing Village infrastructure, including a sanitary overflow system, which will remain undisturbed and lies outside the development area. Due to these unique encumbrances, the school district is requesting relief from including these portions in the total area calculated for stormwater detention, as doing so presents a hardship, particularly given the site's use as a publicly funded school. The request aims to comply with MWRD's Watershed Management Ordinance. The petitioner has stated that the development will meet all MWRD stormwater requirements and will significantly enhance local drainage and reduce runoff impacts on Village sewer infrastructure. Staff finds that the development code exception standards have been met and supports the request for an exception. 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 also need to consider whether any condition of approval or whether a denial of the application would frustrate or thwart the obligations imposed by State laws on the unit of local government. 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. HAPLAMPIanning & Zoning COMM\P&Z 2025\Staff Reports\PZ-07-25, PZ-10-25 700 W Lincoln St (Fina( PUD, Final Plat of Subdivision),, docx.docx Commission, the Planning & Zoning Commission should consider: 1. The relationship of the new school to the education obligations of District 57; 2. The plausible alternatives for any of the relief requested; and & The negative effects on District 57 if relief is not granted. Some parts of the Illinois Schol Code applicable to District 57 and potentially relevant here: Areas of education taught, 105 ILCS 5/27-1, "The State of Illinois, havingthe responsibility of defining requirements for elementary and secondary education, establishes that the primary purpose of schooling is the transmission of knowledge and culture through which children learn in areas necessary to their continuing development and entry into the world of work. Such areas include the language arts, mathematics, the biological, physical and social sciences, the fine arts and physical development and health. Each school district shall give priority in the allocation of resources, including funds, time allocation, personnel, and facilities, to fulfilling the primary purpose of schooling." 2. Elementary school civics course of study, 105 ILCS 5/27-3.10, "In addition to the instruction required to be provided under Section 27-3 of this Code, every public elementary school shall include in its 6th, 7th, or 8th grade curriculum, beginning with the 2020-2021 school year, at Least one semester of civics education, which shall help young people acquire and learn to use the skills, knowledge, and attitudes that will prepare them to be competent and responsible citizens throughout their lives. Civics education course content shall focus on government institutions, the discussion of current and societal issues, service learning, and simulations of the democratic process. Civics education in 6th, 7th, or 8th grade shall be in accordance with Illinois Learning Standards for social science. Additionally, school districts may consult with civics education stakeholders, deemed appropriate by the State Board of Education, with regard to civics education curriculum for 6th, 7th, or 8th grade." 3. Physical education and training, 105 ILCS 5/27-5, "Physical education and training. School boards of public schools and the Board of Governors of State Colleges and Universities shall provide for the physical education and training of pupils of the schools and laboratory schools under their respective control, and shall include physical education and training in the courses of study regularly taught therein. The physical education and training course offered in grades 5 through 10 may include the health education course required in the Critical Health Problems and Comprehensive Health Education Act." 4. Courses in physical education required, 105 ILCS 5/27-6(a), "Pupils enrolled in the public schools and State universities engaged in preparing teachers shall be required to engage during the school day, except on block scheduled days forthose public schools engaged in block scheduling, in courses of physical education for such periods as are compatible with the optimum growth and developmental needs of individuals at the various age levels except when appropriate excuses are submitted to the school by a pupil's parent or guardian or by a person Licensed under the Medical Practice Act of 1987 and except as provided in subsection (b) of this Section." HAPLAMPlanning & Zoning COMM\P&Z 2025\Staff Reports\PZ-07-25, PZ-10-25 700 W Lincoln St (Final PUU, Final Plat of Subdivision).docx.docx The school district is requesting zoning relief for: building height, perimeter landscape screening, foundation landscaping, signage, storm water detention, planting islands, planting ratios, and the track & field encroachment into the exterior side yard. D57 has indicated that granting the requested relief serves the public interest, as the proposal seeks to balance zoning and development requirements with the district's educational objectives and fiscal responsibilities. The district notes that the project is funded by the community and must remain within a limited budget while still meeting the needs of students and staff. STANDARDS AND FINDINGS The Planning and Zoning Commission shall review the standards and findings off act 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.

Exhibit A Standards and Findings of Fact CONDITIONAL USE STANDARDS Section 14.203.F.8 of the Village of Mount Prospect Zoning Ordinance provides that a Conditional Use shall conform to the following requirements: 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; 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; 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 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 pursuantto the recommendations of the planning and zoning commission. ,i_ti.n, „j,pg: The petitioner states that the proposed use for the subject property is for the construction of a replacement middle school, the same as currently on site, that serves grades 6-8. Per the petitioner, the conditional use is publicly operated and promotes a public interest or benefit. The petitioner explains that the construction of the new school is anticipated to begin during the fall of 2025 with use of the existing school concurrent with new construction, and the existing school is anticipated to be demolished at the beginning of summer of 2027. Conditional use approval is requested as there will be a period where multiple principal structures will exist at the same time. The petitioner has responded that the conditional use will not be detrimental to, or endanger the public health, safety, morals, comfort, or general welfare. The petitioner states that the overlap of principal structures is located on property owned by D57, and construction will be managed by a construction manager to oversee the construction process and safety of the site. Per the petitioner, 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 as the construction manager will abide by the Village requirements for hours of operation and coordinate work for public utilities. The petitioner provides that the result will be a new, modern facility that enhances the educational experiences of students, parents, teachers, and all stakeholders. The petitioner asserts that the temporary condition of multiple principal structures located on a site solely owned by the school district will not impede the normal and orderly development and improvement of the surrounding property for uses permitted in the district. The petitioner states that adequate public utilities, access roads, drainage and/or necessary facilities will be provided during the period while both the existing school is utilized, and the new school is under construction. The petitioner notes that the proposed development increases the number of on -site parking stalls and creates a queuing lane to help minimize and alleviate traffic congestion in the public streets. A separate entrance/exit for buses is also proposed and remote from the parent vehicular entrance/exit. Duringthe period while both the existing H:\PLAN\Planning & Zoning COMM\P&Z 2025\Staff Reports\PZ-07-25, PZ-10-25700 W Lincotn St (Final PUD, Final Plat Df Subdivision).docx.docx school is utilized and the new school is under construction, the construction manager will manage construction activities and site usage to minimize traffic congestion in the public streets. The petitioner further states that the conditional use is in keeping with the objectives of the Village, and that the ability to construct the new school while the existing school is still fully utilized will maintain the sense of place and school community without displacing the student population. The petitioner concludes that the conditional use conforms to the applicable regulations of the district in which it is located except as modified via PUD. S-t'w_ipnj„0g: Staff has reviewed the petitioner's request for conditional use approval for a planned unit development and finds that the applicable standards have been met. The conditional use is aligned with the Village's Comprehensive Plan and Future Land Use Plan's designation of the subject property as institutional land use. The proposed new school and associated site improvements represent an upgrade to an essential public facility and are not expected to endanger public health, safety, morals, comfort, or general welfare. The information provided also does not suggest that the proposal will generate nuisances that will be injurious to the uses and enjoyment of other property in the immediate vicinity. Based on the information submitted, the surrounding uses, and the proposed development's compliance with the Village's zoning ordinance and long-range planning document, staff recommends approval of the conditional use request. GENERAL STANDARDS FOR PLANNED UNIT DEVELOPMENTS Section 14.504.A of the Village of Mount Prospect Zoning Ordinance provides that a Planned Development (PUD) 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. ".tK"ll.rlf,"_j,i,pg: The petitioner states that the proposed development complies with the regulations of the R-1 district except as modified by the approved planned unit development. The petitioner states that the principal use of the proposed planned unit development is a replacement middle school for the existing, outdated middle school currently on the same property, and the new middle school is in the public interest because it provides a modern educational environment for the community and addresses enhanced learning opportunities and safety concerns. The petitioner asserts that safety for students and vehicles has been a priority in the design of the new school site access. The proposed site plan separates parent vehicles (entry from Lincoln Street) from buses/delivery vehicles (entry from Can Dota Avenue). Additionally, a dedicated stacking lane within the main parking lot has been created for parents to queue during drop-offs and pick-ups to relieve street parking. HAPLAWPlanning & Zoning COMM\P&Z 2025\Staff neports\PZ-07-25, PZ-10-25 700 W Lincoln St (Final PUD, Final Plat of Subdivision`.domdocx St ff' .. ind .rlg : The development will conform to the bulk requirements and allowed uses in the R-1 zoning district; provides sufficient off-street parking; adheres to the Village's Comprehensive Plan and Future land Use Plan designating the subject property as an institutional land use; is in the public interest to modernize a public facility and essential service; and will not create inconvenient or unsafe access, traffic congestion in the streets, or excessively burden public parks, recreation areas, schools, and other public facilities which serve the Planned Unit Development. 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 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. .pfttioner' _lFi.ings: The petitioner states that it is in the public interest to grant relief as requested because as a municipal entity, D57 is balancing and addressing zoning and development requirements with educational needs and a limited budget funded by the community. The petitioner further states that the relief requested and the new school will enhance the existing site with a new building and site tailored to the needs of students and educational goals. The petitioner explains that impacts to other properties have been minimized, and relief is requested solely to promote better development of the new school for all stakeholders - students, parents, teachers, and community members. The petitioner HAPLAMPlanning &Zoning COMM\P&Z 2025\Staff Reports\PZ-07-25, PZ-10-25 700 W Lincoln St (Final PUD, Final Plat of Subdivision)„docx.docx acknowledges that all setbacks, landscape screening, and open space have been addressed as indicated on the submitted drawings. S,ta-Findings: Staff finds that the requested relief serves the public interest and supports the goal of promoting better development that will benefit students, adjacent residents and the Village as a whole. Staff finds that the petitioner has demonstrated good faith by engaging with concerned neighbors and developing strategies to mitigate potential impacts associated with the new school. Steps have been taken to provide sufficient screening to protect the privacy and livability of adjacent single-family residential uses. Additionally, the school district is in the process of revising its plans to address the building setback requirements in accordance with the warranty deed restrictions to further minimize impacts on neighboring properties. 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 properly; 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 property values within the neighborhood. Petbom.C.S Ej.n.dins: The petitioner states that the existing conditions of the site include a large portion encumbered by Village infrastructure (sanitary overflow system located at the west end of the site) that will remain undisturbed and outside of the development area. Relief is requested to exclude this area from the total area for stormwater detention, in addition to other portions of the site that will not be disturbed by construction. The requirement to provide stormwater detention for this area is a specific hardship to the Owner due to the nature of the property. The petitioner states that the existing encumbrances are unique to this site. Additionally, this project and site is for a public school supported by limited public funds. D57 would like to balance the needs of all stakeholders with responsible management of the construction budget. The petitioner contends that requested exception is not generally applicable to other property within the same zoning classification. The petitioner explains that the purpose of the exception is to adhere to local (MWRD) stormwater management requirements while HAPLAMPtanning & Zoning COMM\P&Z 2025\Staff Reports\PZ-07-25, PZ-10-25 700 W Lincotn St (Final PUD, Final Plat of Subdivision).docx,docx also accounting for the unique site encumbrances that are not readily accommodated by the Village Code and is not based primarily upon a desire to increase financial gain. The petitioner asserts that the proposed development will be in full accordance with MWRD stormwater management requirements outlined in the Watershed Management Ordinance (WMO), and the improvements will result in a substantial watershed benefit to local Village sewers through the incorporation of stormwater management provisions. The petitioner points out that these are not present in existing conditions and the entirety of the site is undetailed. The petitioner states that the exception will have no impact on visual aesthetics or character of the neighborhood and primarily pertains to below grade stormwater improvements. Lastly, the petitioner reasons that the proposed exception will have no impact outside of drainage and stormwater management considerations. According to the petitioner, the development will be designed so as to not impede drainage from adjacent properties and provide stormwater detention and volume control storage in accordance with MWRD requirements resulting in a sizable positive impact on local drainage characteristics and runoff to Village sewer infrastructure, which are directly attributed to the proposed improvements. Staff' s.Fj.rtd : Sections 15.401(B) and 15.402(B) of the Village Code require that stormwater detention be provided for the entire site when a new building is constructed. It would seem appropriate that the easement area over the Village's sanitary overflow system located at the west end of the site be exempted. Staff finds that the development code exception standards have been met and supports the request for an exception.

M WIRE FRAUD ALERT This Notice is not intended to provide legal or professional advice. If you have any questions, please consult with a lawyer. All parties to a real estate transaction are targets for wire fraud and many have lost hundreds of thousands of dollars because they simply relied on the wire instructions received via email, without further verification. If funds are to be wired in conjunction with this real estate transaction, we strongly recommend verbal verification of wire instructions through a known, trusted phone number prior to sending funds. In addition, the following non-exclusive self-protection strategies are recommended to minimize exposure to possible wire fraud. • NEVER RELY on emails purporting to change wire instructions. Parties to a transaction rarely change wire instructions in the course of a transaction. • ALWAYS VERIFY wire instructions, specifically the ABA routing number and account number, by calling the party who sent the instructions to you. DO NOT use the phone number provided in the email containing the instructions, use phone numbers you have called before or can otherwise verify. Obtain the number of relevant parties to the transaction as soon as an escrow account is opened. DO NOT send an email to verify as the email address may be incorrect or the email may be intercepted by the fraudster. • USE COMPLEX EMAIL PASSWORDS that employ a combination of mixed case, numbers, and symbols. Make your passwords greater than eight (8) characters. Also, change your password often and do NOT reuse the same password for other online accounts. • USE MULTI -FACTOR AUTHENTICATION for email accounts. Your email provider or IT staff may have specific instructions on how to implement this feature.

Since our school district operates as a non-profit entity, we do not have proof of tax payments. However, we are happy to provide any alternative documentation that may fulfill this requirement. Regarding proof of ownership, we currently have a title search in progress through TFW Consulting, Inc. Once the search is completed, we will provide the necessary documentation. Additionally, please let us know if any other supporting materials are required. Thank you for your assistance with this process. Please don't hesitate to reach out if further clarification is needed.

Prospect School District 57 (D57), we hereby submit this Preliminary and Final Planned Unit Development (PUD) for the new construction/replacement of Lincoln Middle School located at 700 West Lincoln Street. In November 2024, residents approved an $85 million referendum to address critical needs for D57 including the replacement of the aging middle school which faced challenges such as outdated classrooms, inadequate space, and aging infrastructure. The new construction will provide a modern, accessible facility designed to support innovative learning and the needs of today's students. Project Summary This project includes new construction for a replacement middle school, the demolition of the existing school, and related site work. The project provides a tremendous opportunity for D57 to implement a new learning environment tailored to the changing needs of middle school age students and one which supports new instructional and teaching pedagogies as well as social/emotional support systems. New construction is anticipated to begin in Fall 2025 for completion August 2027. Construction will run concurrently with the existing school utilized until Summer 2027. Demolition of the existing main school building and new site work is anticipated in Summer 2027. A phasing schedule and diagrams are included in this submittal provided by the Construction Manager, Nicholas & Associates. Conditional use is requested due to operational logistics and the construction schedule as multiple principal structures will co -exist until the existing school is demolished. Elements of the new building include: • 3-story academic wing (student core classrooms) - one floor for each grade level • 2-story Administration, Learning Resource Center, and Encore/Broad Experience classrooms • Storm Shelter (Band/Orchestra/Music wing, required for new school construction) • Gym • Cafetorium (Cafeteria with Stage) • Maintenance and Support areas OVER rIF1"Y YEARS OF ENHANCING NOW ENVISIONING FUTURES Mt. Prospect School District 57 STIR #24080, D57 Lincoln Middle School 8/14/25 Village of Mt. Prospect- Planned Unit Development Page 2 of 9 • Outdoor learning/gathering space Elements of the new site plan include: • New larger parking lot along Lincoln Street (see site plan, visitor parking located separate from general use parking stalls) • Parent drop-off and queuing lane • Separate entry/exit for buses and delivery trucks • A continuous fire lane around the new building • Fire hydrants located around the entire building • A below -grade stormwater volume control and detention storage (no detention storage on site currently for the existing school) • 200-meter track at southeast corner of the site Demolition includes the existing one-story maintenance building (designed in 1961) and the existing one-story and two-story main school building (original building constructed in 1950 with additions 1953-1969). Existing hardscape and landscape areas are to be demolished for new construction as needed. Construction assemblies and materials for the new building are being explored for cost and aesthetic choices. It is anticipated that, for two-story and three-story portions of the new building, structural steel framing with cold -formed metal framing infill and masonry/rainscreen system will be utilized. The storm shelter and Gymnasium may be pre -cast concrete wall structures with structural steel roof systems. Other one-story portions of the building may be load - bearing masonry. Exterior elevations provided with this submittal are preliminary. Final material and color selections are to be reviewed and approved by D57 within the coming weeks. Updated renderings will be provided to the Village of Mt. Prospect when elevations are finalized. The tallest portion of the new building is anticipated to be approximately 50' for the 3-story academic wing (14' floor -to -floor height + parapet for roof top equipment screening). The size/dimensions of the roof top mechanical equipment is still to be determined. Elevations show anticipated sizes and locations. Zoning relief is requested for the 40' zoning height limit as the concept of three floors/"houses" (one for each grade level) is central to instructional and social objectives. The proposed project is compatible with the existing use of the site. The proposed building compactly provides new instructional areas to address student -centered learning requirements and collaboration within the academic wings and throughout the new school. A new single larger gymnasium (versus the existing 2-gymnasium model) consolidates space and functionally Mt. Prospect School District 57 STIR #24080, D57 Lincoln Middle School 8/14/25 Village of Mt. Prospect- Planned Unit Development Page 3 of 9 allows for shared instruction and synergies. The new larger Cafetorium will allow all grade level students to experience lunch together. It also provides a new stage area with flexible scheduling for instruction and performances. The proposed building is sited with the tallest portion of the building located central to the site and closest to the existing building to minimize impact to neighbors. The resulting green spaces at the west and north are intended to be used by physical education classes, as they are currently, and no hardscaping is desired in these areas which could potentially cause injury to students. The resulting field and track at the southeast corner of the site (after the existing school and parking lot are demolished) will provide the neighborhood with easily accessible green space and amenities when not in use by the school. D57 is committed to being a good neighbor throughout this construction project. Meetings and website updates are being provided to encourage and keep an open dialogue with the community. D57 is also working closely with the CM to address safety and site concerns. This project is an opportunity to develop a building and site that will continue to provide for the community for years to come. We look forward to working with the Village of Mt. Prospect to see it come to fruition. Responses to the Village of Mt. Prospect Concept Plan Review Comments: Overall Site Plan, Layout, and Engineering Traffic Comments 1.

If non -emergency vehicles are not to use this driveway, and if the fire lane complies with ADA/IAC slope restrictions, it may serve as an accessible pedestrian path. Otherwise, we suggest installing a separate ADA/IAC compliant sidewalk around the north, west, and south sides of the building. If a separate sidewalk is installed, we suggest striping a crosswalk across the drive -aisle, and striping one (1) space as NO PARKING to facilitate pedestrian access across the parking lot. :ff,l'I s os °'uI'' PXI(Jas�vc tlipuw( too uv.P(J vaIo; `.`+:'hool "Swain ,' kaP" cc ur, Me in!

Relief is requested as a primary objective for this project is to provide dedicated floors for each grade level (6th, 7th, and 8th Grades). Three floors provide the opportunity to implement a new learning environment tailored to the changing needs of middle school age students, consolidates teaching, supports new instructional and teaching pedagogies, provides a sense of student identity, and enhances social/emotional support systems. • Perimeter Landscaping Screening - As reviewed with the Village of Mt. Prospect at the meeting on May 5th, the design intent is to remain a good neighbor and provide some screening to adjacent properties while maintaining the open view/access that many neighbors currently find an asset. The existing green space area is currently used for physical education athletic fields, and the proposed use is intended to remain the same. Additional shade trees have been added around the perimeter. The requirement for evergreen shrubs along the southeast/new proposed athletic track and field has been provided at approximately 50% coverage as this area is intended to welcome neighbors and will be made available for community use when not used by D57. • Foundation Landscaping - Proposed landscaping includes foundation planting at the building elevations facing Lincoln Street and Can-Dota Avenue which are the primary public street views of the new building. Relief for foundation landscaping at the north and west elevations is requested as these Mt. Prospect School District 57 STIR #24080, D57 Lincoln Middle School 8/14/25 Village of Mt. Prospect— Responses to Standards Page 5 of 6 are pedestrian/private views from neighboring backyards. Installation and maintenance for additional foundation landscaping at these areas will draw resources from other educational areas. • Signage — See exhibits for proposed signage. Included are the following signs: — architectural site detail sheets: entry monument sign and track & field sign — exterior elevations sheets: building wall mounted sign at east end of 3-story academic wing, entry canopy sign, & visitor entry sign Relief is requested for the number of signs, content (copy contains more than 10 items of information), the entry canopy sign (area of secondary sign exceeds maximum of 4 square feet), and the orientation for the sign at the track/field (honorary naming to be visible from both sides and parallel with the long jump to best utilize the limited green space and maintain student safety; additionally, this sign to be located within the yard setback). Regarding signage content, Lincoln Middle School is a very common school name in Illinois; proposed signage includes the full district name for identification. The primary 3-story building is set back from Lincoln Street property line by approximately 225 feet, the wall mounted signage at the east is intended to identify the building from the street. The canopy mounted signage is intended to signify the visitor entry area with visitor signage mounted at the designated door below. • Storm Water Detention — Relief is requested for providing storm water detention for the entire site. Storm water proposed is limited to development areas per MWRD standards. • Planting Islands — Relief is requested for requirements to be at least one hundred twenty (120) square feet in area, and at least seven feet (7') in width, as measured back of curb to back of curb. Most islands meet this requirement. The location in question is located at the west parking lot, north end near the bicycle racks. • Planting Islands — Relief is requested for the requirement of islands to be provided for every seventeen (17) parking spaces in a parking row. At the main parking lot, achieving an increase to the number of parking stalls and simplifying snow plowing is desired. The central area is also striped to allow pedestrian access from within the parking lot. • Plant Species — Relief is requested for the requirement of fifty percent (50%) of shrubs shall be deciduous and fifty percent (50%) evergreen. Our landscape architect respectfully requests a mix of 70% deciduous and 30% evergreen due to the number of plantings on this project and their proximity to pavement areas that will be subject to de-icing agents. Typically these conditions are not conducive to healthy evergreens. • Encroachment into Exterior Side Yard — Relief is requested for the encroachment into the exterior side yard at the southeast corner of the track & field. This portion of the property is currently owned by District 57. During the Concept Review process, the Village of Mount Prospect requested that this portion of the property be dedicated to the Village of Mount Prospect to provide a consistent right of way width along the entire frontage of the school property, and to cause the existing sidewalk to be located on Village property. District 57 is willing to accommodate this request and has included this revision in the Plat of Consolidation application. As a result of this new dedication, a portion of the track now encroaches the side yard. Mt. Prospect School District 57 STIR #24080, D57 Lincoln Middle School 8/14/25 Village of Mt.

Lincoln St / Conditional Use Approval for Preliminary and Final PUD / Review #4 Dear Ms. Moon, The Village of Mount Prospect has reviewed the third submittal for conditional use approval for a preliminary and final planned unit development for Lincoln Middle School at 700 W. Lincoln Street, Mount Prospect. Staff has the following review comments: Planning Division: 1. Please be advised that any changes to the overall height of the building will require changes to the interior side yard building setbacks. 2. Any future modifications to the project will require either administrative approval or a formal amendment to the planned unit development. Plat of Consolidation/Subdivision: 3. The Plat proposes vacating 50-foot building lines that were previously established in a warranty deed (see attached warranty deed, Document No. 1496957). It is advised to confirm with the Title Company that the School District has the authority to vacate the building lines by recording the Plat. Based on the details of the Warranty Deed, determine what would be necessary to remove Exception #27 from title, therefore ensuring that building over the 50-foot building line would not be considered an encroachment. 4. Please review all comments provided in the review letter for the plat of subdivision under PZ- 10-25 dated June 17, 2025. 5. A portion of the school building still encroaches within the 50-foot building setback as required in the warranty deed; planning staff (Ann Choi) discuss this issue with STR Partners (Sandra Moon) who had stated that D57 is aware of the encroachment, has reviewed the issue Village of Mount Prospect Building Services I Page 2 with their attorney, and will proceed based on the existing one-story brick building that is already located within the 50-foot building setback. Public Works Department: 6. PW has reviewed the revised information submitted on September 11 and 14, 2025 for conditional use approval for the Lincoln Middle School proposed at 700 W. School Street. The last remaining comment, detailed in our comments dated July 23, 2025, has been largely addressed. The plan now includes a NO LEFTTURN sign at the new driveway onto Can Dota Avenue. To better restrict the left turn movements, the driveway should be signed and striped as noted below: Please note that the plans as submitted are sufficient to recommend approval of the requested conditional use. The signage and striping details noted above will be implemented as part of the building permit submittal. Village of Mount Prospect Building Services I Page 3 It must be understood that the comments listed above reflect issues noted during a review of the requested conditional use. A thorough review of the site design and details will be performed as part of the building permit review process. Building Department: 7. Work shall be coordinated with the Board of Education permit and building as necessary. VOMP Building does not review and inspect schools for permit/building work. Fire Department: Please advise the petitioner that the following items must be included in the building/site plans submittal: 8. Afire sprinkler system and standpipe system in accordance with NFPA 13 and NFPA 14 will be required for this project for all buildings. Ensure fire sprinkler shop drawings, hydraulic calculations, and equipment cut sheets are submitted for review. Village of Mount Prospect Fire Prevention Code, 24.202 9. Afire alarm system will be required for this project. Ensure that the fire alarm shop drawings with point-to-point wiring diagrams, battery load calculations, and equipment cut sheets are submitted for review. Village of Mount Prospect Fire Prevention Code, 24.202 10. Before final approval, a State of Illinois Fire Marshal inspection/ ROE will be required. 11. Afire pump and standpipe system(s) will be required for this building. Please ensure that drawings are submitted for these systems to the Fire Department for review.

Lincoln Street, Mount Prospect. The plat of resubdivision is not approved at time. Staff has the following review comments: Planning Division: 1. Planning staff has reviewed the following documents which are attached to this letter: a. Alta Commitment for Title Insurance, Commitment No. 25003257VH b.

The Village of Mount Prospect must be removed from the title commitment as the owner of Parcel 1 based on the quit claim deed (Exhibit 5). Public Works Department: 3. No further PW issues. Village of Mount Prospect Building Services I Page 2 Legal Division: 1. To consolidate PINs, all of the PINs subject to the consolidation must be owned by the same entity. 2. The title commitment provided by Chicago Title with the commitment no. 25003257VH currently reflects that Parcel 1 (PIN: 08-11-214-037-0000) is owned by the Village of Mount Prospect. However, there exists a Quit Claim Deed (see Exhibit 5) granting ownership of this parcel "...for the use and benefit of School District Number 57...". To update title to reflect ownership of Parcel 1 by the School District, the next step would be to email the Quit Claim Deed to the Chicago Title Vernon Hills office (ctvernonhills(@ctt.com). Request that the underwriter for title commitment no. 25003257VH review the Quit Claim Deed and update title accordingly. 3. Upon review of the Quit Claim Deed, the title commitment should be updated to reflect School District ownership of Parcel 1, thus verifying ownership of all Parcels in the Plat of Consolidation by the School District. 4. The Plat proposes vacating 50-foot building lines that were previously established in a Warranty Deed (see Exhibit 3). It is advised to confirm with the Title Company that the School District has the authority to vacate the building lines by recording the Plat. Based on the details of the Warranty Deed, determine what would be necessary to remove Exception #27 from title, therefore ensuring that building over the 50-foot building line would not be considered an encroachment. 5. The Plat of Consolidation should be executed with the remaining necessary signatures before it is sent for recording.

IJR61141i797:�OTTAURT1hlyilr>0111,04161" Choi, Ann From: Sent: Friday, August 1, 2025 12:00 PM To: Choi, Ann; Botterman, Casey Subject: Written Comment for Lincoln School Petitioner Dear Mount Prospect Zoning, Community development, Water Division and Mr. Kaiz, I have lived in Mount Prospect for over 13 years and recently moved to a home on the 300 block of S. Can Dota Ave directly across from Lincoln middle school. I have a lot of concerns and do not feel very comfortable with updates or implementation of the construction exceptions of Lincoln school stated with the petitioner STIR Partners LLC and Mount Prospect School District. A main concern is the proposed service driveway to the back of Lincoln school. According to the renderings, this entrance is directly across from my driveway at 305 S Can Dota, I would like some clarity on where the entrance would be specifically and its use. This is not very appealing to my property and would like to know if this a main vehicle road for students/parents, supplies/resources or drop offs. In addition to this, the updates available online have not been specific to the surrounding neighbors. Questions such as the following should be addressed- if there will be continued parking restrictions during school hours on the 300 block of S Can Dota, how will drop off and pick up be adjusted for the 2025 school year, update on street repair, update of water main repair and overall what to expect in a timely fashion going forward. I feel there has been a lack of communication and living here has been disrupted week to week. The streets have had major potholes/major damage for an extended amount of time, which do not believe is acceptable. I understand there is a water main and street repair and to be patient, but either the contractors took on too much, don't have the resources or there was a lack of planning to take these jobs in a timely manner. Many neighbors and I have not been able to open windows because of the excess dust and debris from the traffic. I get a powdery coating of dirt/dust on my cars, inside my garage and inside my house for the last 2.5 months. have concern on moving forward with exemptions because of the lack of communication, updates, efficiency and expectations to complete projects in a timely manner. I, Like many neighbors, would appreciate further information going forward and contact information from our village. I have enjoyed living here in Mount Prospect, but discourage changing zoning rules until further information is delivered to the community.

PZ-07-25 & PZ-10-25 Hearing Date: August 14, 2025 PROPERTY ADDRESS: 700 & 804 West Lincoln Street PETITIONER: STR Partners LLC (Sandra Moon) PROPERTY OWNER: Mount Prospect School District 57 Jason Kaiz, Assistant Superintendent for Finance and Operations PUBLICATION DATE: July 30, 2025 REQUEST: 1) Final Plat of Subdivision titled "Lincoln Consolidation"; 2) Conditional Use Approval for a Preliminary and Final Planned Unit Development; and 3) Development Code Exception MEMBERS PRESENT: Joseph Donnelly Ewa Weir Walter Szymczak Michael Fricano Richard Rogers William Beattie Donald Olsen MEMBERSABSENT: None STAFF MEMBERS PRESENT: Antonia Lalagos— Development Planner Ann Choi — Development Planner Jason Shallcross — Director of Community & Economic Development INTERESTED PARTIES: STR Partners LLC Mount Prospect School District 57 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 two items of new business, Chairman Donnelly introduced case number PZ-07-25 and PZ- 1025, 700 & 804 West Lincoln Street, a request for a final plat of subdivision and a preliminary and final planned unit development (PUD). Planning & Zoning Commission Meeting —August 14, 2025 PZ-07-25, PZ-10-25 Planning staff member, Ann Choi, introduced Zoning Case Nos. PZ-07-25 and PZ-10-25. Ms. Choi stated that the petitioner, STR Partners LLC, on behalf of the Mount Prospect School District 57, is seeking conditional use approval for a preliminary and final planned unit development to replace an existing middle school with a new 127,000-square-foot school and complete related site modifications at 700 and 804 West Lincoln Street. Ms. Choi stated that the petitioner is also seeking approval of a final plat of subdivision for the consolidation of existing school lots and to vacate a portion of the school property. Ms. Choi further stated that the petitioner is requesting a development code exception and explained that the proposal requires Village Board approval for the conditional use for a preliminary and final planned unit development, final plat approval, and for the development code exception. Ms. Choi provided a brief history of the subject property and stated that the subject property was annexed into the Village in 1925 and is bordered by Lincoln Street to the south, Can Dota Avenue to the east, and single-family residences to the north and west. Ms. Choi stated that the site is currently occupied by Lincoln Middle School that was originally constructed in 1953. Permit records show that the school has since undergone multiple additions, and a maintenance building was constructed in 1962. Ms. Choi explained that in November 2024, residents approved an $85 million referendum to address critical needs within the school district, and according to the petitioner, these needs include the replacement of the existing middle school, which has struggled with outdated classrooms, limited space, and aging infrastructure. Ms. Choi presented the architectural site plan. Ms. Choi stated that the petitioner proposed to construct a new 127,000-square-foot replacement middle school, demolish the existing building, and complete related site improvements. Ms. Choi explained that the new school includes a 3-story academic wing including the students' core classrooms, a 2-story administration area, a learning resource center, experience classrooms, a storm shelter, gym, cafetorium, maintenance and support areas, and an outdoor learning/gathering space. Ms. Choi stated that construction of the new facility is anticipated to begin in the fall of 2025, with completion targeted for August of 2027. Ms. Choi explained that the new school will be built while the existing school remains operational, with both structures coexisting on the site until the summer of 2027. Conditional use approval is required as two principal structures will be present on the property during the transition period. Ms. Choi added that the petitioner also requests relief from Sections 15.401(B) and 15.402(B) which require stormwater detention to be provided for the entire site when a new building is constructed. Ms. Choi presented a slide of the proposed phasing for the project that includes the following target dates: • The project is estimated to begin in October of 2025, and the existing school building areas (B C D E), south side drop-off lane, and the east side drive and parking area will remain active during construction. • The new school building (A) is anticipated to start in October of 2025 and will be completed by May of 2027. • The new below -grade detention system will be installed during the summer of 2026. • The demolition of the central and southern portions of the school (D C E) will commence in May/June of 2027. All building demolition will be completed by August of 2027. • The new south side parking lot will begin once the central and southern portions of the existing school have been demolished. Ms. Choi went onto present the traffic and parking for the proposed development. Ms. Choi explained that the Village requires schools serving grades K-8 to provide 1 parking space/employee, plus 8 visitor spaces, Planning & Zoning Commission Meeting —August 14, 2025 PZ-07-25, PZ-10-25 and based on the staffing level of 91 employees, the school is required to provide 99 parking spaces. Ms. Choi stated that the current parking lot provides a total of 77 parking spaces. Ms. Choi noted that the proposed site plan includes a total of 106 parking spaces, exceeding the Village's parking requirement and representing a net increase of 29 parking spaces compared to the current condition. Ms. Choi explained that the additional parking will significantly improve overall site functionality and better accommodate daily operations and visitors. Ms. Choi went on to state that long-term staff parking will be Located in the large south parking lot, while visitor parking wiLL be designated in the smaller southwest Lot. Ms. Choi indicated that the north lot will be used exclusively for bus drop-offs and pick-ups, with no long-term bus parking on site. Finally, Ms. Choi stated that an additional 9 parking spaces at the northeast corner of the buiLdingwill be reserved for maintenance and food service personnel. Ms. Choi pointed out that the Public Works department expressed concerns related to turning movements from the school's new driveway onto Can Dota Avenue. Ms. Choi explained that the short 75-foot offset between Milburn Avenue and the proposed driveway may potentially lead to collisions between a bus and another vehicle performing simultaneous Left turns. When making a Left turn onto Can Dota Avenue, stopping distances may be insufficient to avoid collisions if vehicles turn simultaneously. Ms. Choi stated that at 15 miles per hour (mph), passenger vehicles require about 80 feet to stop, increasing to 115 feet at 20 mph; buses require even longer distances. Ms. Choi stated that this limited space increases the risk of conflicts. Because of this safety concern, the Public Works Department remains committed to prohibiting left turns out onto Can Dota Avenue. Ms. Choi added that the left turn restriction is included as a condition for the Planning and Zoning Commission's recommendation to the Village Board. Ms. Choi presented the proposed building elevations and noted that they feature a contemporary institutional design, characterized by clean lines, a mix of durable materials, and articulated massing. Ms. Choi pointed out that the exterior incorporates brick masonry, fiber cement panels with a wood -like appearance, aluminum storefront systems, and aluminum -composite metal paneling, which provide visual interest and durability. Ms. Choi noted that the facades are articulated through changes in plane, material transitions, and patterns to help break up the overall massing, and the color palette consists of warm, neutral tones. Ms. Choi stated that rooflines are varied in height, while all rooftop mechanical units will be screened from view, and that ground -mounted mechanical/utility equipment, as well as the trash enclosure, will be screened with brick masonry walls. Ms. Choi described the gradual stepping down of taller building elements to shorter elements, organized according to the function of the spaces, and noted that the proposed design is appropriately scaled to the surrounding single-family residential neighborhood, resulting in contextually sensitive massing and a pedestrian -friendly scale. Ms. Choi invited the public to viewthe materials samples board provided by the petitioner and staged at the back of the Village Board room. Ms. Choi noted that the exterior incorporates brick masonry, fiber cement panels with a wood -like appearance, aluminum storefront systems, and aluminum -composite metal paneling, which provide visual interest and durability. Ms. Choi advanced to the landscape plan and reported that the existing landscaping will remain along the north, west and south property lines and additional canopy trees have been added along the west property line. Ms. Choi stated that perimeter landscaping, consisting of a variety of existing deciduous trees, new canopy trees, and a combination of deciduous and evergreen shrubs, will be provided along the south property line. Ms. Choi further stated that a considerable amount of foundation landscaping will also be provided along portions of the building's north, south and east facades. The petitioner is requesting relief from strict conformance of the foundation and perimeter landscaping requirements. Foundation Landscaping will not be provided along most of the north and the entirety of the west elevations since these Planning & Zoning Commission Meeting —August 14, 2025 PZ-07-25, PZ-10-25 facades face private property. Ms. Choi explained that while a 6-foot-tall screen/buffer is required along the length of the rear and interior side yards, a shorter screen/buffer will be provided only in select areas at the southwest and northeast corners of the property, in response to requests from specific adjacent property owners. Ms. Choi further explained that this approach also helps preserve the openness and accessibility of the school's open spaces, which are valued by neighboring residents. Ms. Choi noted that additional trees have been added to the northeast as well as providing additional landscape screening around the discus cage. Ms. Choi went on to explain the proposed signage for the school project. Ms. Choi stated that the petitioner intends to install one wall -mounted sign and one canopy sign on the south elevation facing Lincoln Street. Ms. Choi noted that a new monument sign is also proposed just west of the Lincoln Street driveway and a freestanding sign is proposed along the Can Dota Avenue frontage just east of the track & field. Per the petitioner, relief is requested for: items of information as Lincoln Middle School is a very common school name in Illinois, while the proposed monument sign will include the full district name for identification, and the sign copy contains 12 items of information exceeding the 10 items permitted by code; orientation for the freestanding sign at the track & field (honorary naming will be visible from both sides and parallel with the long jump to best utilize the limited green space and maintain student safety); and sign surface area for the canopy sign (18.5 square feet) which exceeds the 4 square feet permitted for secondary signage. Ms. Choi stated that any future relief requested for signage shall require an application for a minor amendment to the PUD. Ms. Choi transitioned to a slide showing changes to the site plan and explained that the entire school building would shift approximately 15 feet to the north. Ms. Choi explained the reason for the change and stated that while the proposed development meets the Village's setback requirements, the warranty deed affecting the southwest portion of the property imposes a more restrictive 50-foot setback. Ms. Choi further explained that although the current proposal does not encroach into the required zoning setbacks, the petitioner is revising the plans to conform to the 50-foot warranty deed restriction, doubling the setback otherwise required by the zoning code. Ms. Choi stated that the school district has provided the modified plans, and the drawings are currently under staff review. Ms. Choi stated that while the majority of the site impact is at the southwest corner (enlarged fire lane, grading improvements, etc.) there are some resulting changes to the north asphalt/drive north of the building. The south and west parking lots remain the same and the sidewalks near the south side of the building will be modified. Ms. Choi noted that the modified plans will be presented to the Village Board. Ms. Choi advanced to a slide of the subdivision plat and explained that a final plat to consolidate the lots into a single lot is required so that the application of setbacks and other bulk regulations is straightforward. The plat shows that the southern half of the vacated portion of Milburn Avenue west of Can Dota Avenue is included as part of the school district property. Ms. Choi explained that additional right-of-way along the Lincoln Street frontage will be dedicated to the Village, allowing a consistent right-of-way width across the Lincoln Street frontage, and allows the existing public sidewalk to be located on public property. Ms. Choi noted that this new dedication also causes the existing monument sign to be in the public right-of-way and the project will be conditioned to allow the monument sign to remain until such time the sign is relocated onto school property. Ms. Choi indicated that Sections 15.401(B) and 15.402(B) of the Village Code require that stormwater detention be provided for the entire site when a new building is constructed. Ms. Choi explained that the Engineering Division indicated that it would seem appropriate that the easement area over the Village's Planning & Zoning Commission Meeting —August 14, 2025 PZ-07-25, PZ-10-25 sanitaryoverflow system located at the west end of the site be exempted from counting towards the entire site. Any area to be exempted would require a variation from the Village Code that must be granted by the Village Board. Ms. Choi noted that the Engineering Division reviewed the request and supports the request. Ms. Choi explained that when a unit of local government, such as a school 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. Ms. Choi 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 school districts. Ms. Choi stated that the school district is requesting zoning relief for: building height, perimeter landscape screening, foundation landscaping, signage, storm water detention, planting islands, planting ratios, and the track & field encroachment into the exterior side yard. The school district has indicated that granting the requested relief serves the public interest, as the proposal seeks to balance zoning and development requirements with the district's educational objectives and fiscal responsibilities. The district notes that the project is funded by the community and must remain within a limited budget while still meeting the needs of students and staff. Ms. Choi provided that the conditional use is aligned with the Village's Comprehensive Plan and Future Land Use Plan's designation of the subject property as institutional land use. Ms. Choi stated that the proposed new school and associated site improvements represent an upgrade to an essential public facility, and that the zoning approval for the proposed project is also identified as a high priority management agenda item in the Village's 2025-2026 Strategic Plan. Ms. Choi summarized staff's findings, suggesting that the proposal represents an upgrade to an essential public facility and is not expected to endanger public health, safety, morals, comfort, or general welfare. Ms. Choi stated that the information provided also does not suggest that the proposal will generate nuisances that will be injurious to the uses and enjoyment of other property in the immediate vicinity. Ms. Choi stated that staff also finds that the requested relief serves the public interest and supports the goal of promoting better development that will benefit students, adjacent residents and the Village as a whole. Ms. Choi emphasized that the petitioner has demonstrated good faith by engaging with concerned neighbors and developing strategies to mitigate potential impacts associated with the new school. Steps have been taken to provide sufficient screening to protect the privacy and livability of adjacent single- family residential uses. Additionally, the school district is in the process of revising its plans to address the building setback requirements in accordance with the warranty deed restrictions to further minimize impacts on neighboring properties. Ms. Choi stated that staff supports the petitioner's zoning requests, 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, and recommended approval of the following motions: "Motion to approve: 1. Afinal plat of subdivision titled "Lincoln Consolidation", Case No. PZ-10-25; 2.

Ms. Choi stated that the Village Board's decision is final for the case and concluded her presentation. Planning & Zoning Commission Meeting —August 14, 2025 PZ-07-25, PZ-10-25 Chairman Donnelly asked the commissioners if there were any questions for staff. Commissioner Olsen asked: 1) if there would be sufficient parking for staff during construction since it looks like some of the existing parking would be lost, and 2) where would the contractors park. Ms. Choi asked to defer that question to the traffic engineer that was present. Hearing no further questions for staff, Chairman Donnelly invited the petitioners to the stand. Chairman Donnelly swore in the following petitioners and representatives as they appeared at the stand to answer questions: • Sandra Moon, STR Partners (Petitioner and Architect), 350 West Ontario Street, Suite 200, Chicago, Illinois. • Jason Kaiz, School District 57 (Assistant Superintendent for Finance and Operations), 701 West Gregory Street, Mount Prospect, Illinois. • Nicholas Papanicholas, Nicholas and Associates (Construction Manager), 300 North Oak Street, Mount Prospect, Illinois. • Steve Gregory with Erickson Engineering Associates (Landscape Architect), 145 Commerce Drive, Grayslake, Illinois. • Jeff Geldmyer, Eriksson Engineering Associates (Project Engineer), 145 Commerce Drive, Grayslake, Illinois. Mr. Kaiz explained that accommodations would be made within the construction area for the contractors, and that the school anticipates losing about 11 parking spaces for the teachers but that during construction, those 11 parking spaces would be relocated to the on -street parking spaces along Lincoln Street. Commissioner Rogers observed that the south elevation has a high percentage of glazing, especially along the south elevation that would be exposed to the noontime sun and noted the lack of trees or other Landscaping to protect the building from heat entering the south -facing rooms. Commissioner Rogers inquired whether provisions had been made to shade the south -facing windows or if alternative methods would be used. Ms. Moon explained that the glazing was intended to balance daylighting and transparency for students, and noted that high -efficiency, low-E coated glass would be installed to mitigate heat gain. Ms. Moon further responded that roller shades would be provided in each classroom, and that the building's mechanical systems were designed and sized to accommodate the anticipated solar heat gain. Commissioner Rogers followed up with asking if VAV boxes would be provided to control air conditioning and heating. Ms. Moon responded in the affirmative. Chairman Donnelly asked how much height the building was requesting. Ms. Choi responded that the proposed height was 48 feet, not to exceed 50 feet. Ms. Moon clarified that 48 feet represents the overall height of the three-story academic wing. Ms. Moon explained that the decision to construct a three-story building was driven by student needs, with each grade level occupying its own floor to foster a sense of community and to support team -based teaching for sixth, seventh, and eighth grades. Chairman Donnelly followed up with a question regarding rooftop elements, asking whether any structures such as elevator shafts or mechanical equipment would extend above the roofline, noting that this had been an issue in previous projects. Planning & Zoning Commission Meeting —August 14, 2025 PZ-07-25, PZ-10-25 Ms. Moon explained that the proposed building height of 48 feet is measured to the top of the aluminum composite fagade, which extends higher than the actual roof. Ms. Moon noted that rooftop mechanical units would be screened behind the parapet. Chairman Donnelly requested clarification that the rooftop units would not exceed the height of the fagade. Ms. Moon responded that this would depend on the specific equipment selected once the project goes out to bid but confirmed that the intent is to fully screen the units. Chairman Donnelly also asked whether the units would be screened for noise and inquired about the actual roof height. Ms. Moon estimated that the roof itself measures approximately 45 feet, with a parapet extending an additional five feet. Ms. Moon further explained that the roofLine varies in height but that the units would be set back to remain out of sight. Mr. Papanicholas assured the Commission that the construction and design teams would coordinate to ensure effective screening of all mechanical equipment. Mr. Papanicholas noted that, consistent with past commercial projects, the team would prepare exhibits demonstrating compliance with the intent of the code. Mr. Papanicholas stated that rooftop units would be placed as far back as possible to maximize the parapet's effectiveness and that all visible equipment would be screened from both property lines and the public right-of-way. Mr. Papanicholas added that ground -mounted equipment is not recommended for this type of mechanical system. Vice Chairman Beattie recalled a prior project at Prospect High School where concerns were raised about noise from rooftop mechanical equipment when the swimming pool was constructed. Vice Chairman Beattie asked whether the proposed rooftop units would be evaluated not only for visual screening but also for sound impacts. Specifically, Vice Chairman Beattie inquired if any decibel standards were being applied, noting that neighbors had previously complained about hearing equipment running continuously during warmer months. Vice Chairman Beattie asked whether consideration had been given to the effectiveness of rooftop screening in addressing sound impacts in addition to visual aesthetics and questioned how much noise reduction such screening would provide and whether sound Levels would be factored into the design. Mr. Papanicholas explained that ground -mounted equipment placed against masonry buildings can sometimes amplify sound, as hard surfaces cause noise to reverberate. Mr. Papanicholas noted from personal experience with a similar installation at Fairview School that this can increase noise Levels. Mr. Papanicholas stated that screening will be designed to address both visual and sound impacts and confirmed that the development team will workwith staff to minimize noise transmission to surrounding properties. Vice Chairman Beattie sought confirmation that no sound measurements have yet been taken and that the assumption at this stage is that any issues will be addressed through design and mitigation measures as the project advances. Mr. Papanicholas responded in the affirmative. Chairman Donnelly opened the floor for questions from the public. Chairman Donnelly swore in Karen Rosenthal of 307 Can Dota Avenue, Mount Prospect, Illinois. Ms. Rosenthal stated she lives across the street from the existing school parking lot. Ms. Rosenthal inquired whether a fence would be installed along the track and field that is planned to replace the existing parking Lot. She wanted to know if a fence, landscaping, or bushes would be provided as part of the new design. Chairman Donnelly reiterated her question, asking for clarification on the type of fence proposed — whether it would be open -style or solid style that provides partial screening. Planning & Zoning Commission Meeting —August 14, 2025 PZ-07-25, PZ-10-25 Chairman Donnelly swore in Margret Bohac of 806 West Lincoln Street, the first house to the west of 804 West Lincoln Street. Ms. Bohac expressed concern regarding the proposed three-story building located behind her yard and emphasized her desire to maintain darkness in the evening and voiced strong concern that the Lights would be too bright. Chairman Donnelly responded that Village regulations require lighting to be designed so that there are zero foot-candles at the property line. Chairman Donnelly explained that the project would need to ensure that no Light trespasses onto adjacent properties, and staff would verify compliance. Chairman Donnelly referenced the Randhurst development, noting that its three-story parking garage is equipped with tall lights that are designed to minimize spillover, and stated that a similar approach could be expected here. Chairman Donnelly assured Ms. Bohac that if she experienced lighting issues after construction, she could bring her concerns back to staff for review and follow-up. Chairman Donnelly swore in Janet and James Kadlec of 811 West Milburn Avenue, located north of the school site. Mr. Kadlec expressed concern regarding construction parking near their property, noting that contractors parking along Milburn Avenue and accessing the site via the walkway adjacent to their fence would create congestion for residents and visitors. Mr. Kadlec emphasized that contractors should be required to park on -site. Mr. Kadlec further cautioned against Milburn Avenue becoming an overflow parking area for the school once it is built. Mr. Kadlec also raised concerns about flooding, stating that his property had previously been impacted by drainage issues from the school site, requiring him to elevate his garden beds. Mr. Kadlec asked whether the new stormwater detention facilities would adequately handle runoff from the expanded building, parking lot, and athletic field. Chairman Donnelly responded that no water should discharge from the school property onto adjacent lots, and according to the staff report that stormwater detention calculations have been reviewed to ensure compliance, though this will be later confirmed with the petitioner. Mrs. Kadlec inquired about the distance between the new school building and their property line, as well as whether fencing or screening would be provided. Ms. Choi stated that the building would be Located over 150 feet from their lot, significantly exceeding setback requirements. Director Shallcross explained that, while Village code typically requires a six-foot screen, staff did not wish to require fencing along this area since most adjacent homeowners currently use the open green space for recreation and access. Mr. and Mrs. Kadlec also requested access to detailed site plans and exhibits for further review. Chairman Donnelly advised that the petitioner could provide these materials after the presentation and noted that additional review opportunities would be available at the Village Board stage. Chairman Donnelly swore in Dawn Hahn of 305 We Go Trail, whose property is the last along We Go Trail with full access to the field. Ms. Hahn expressed concern regarding stormwater management, referencing issues similar to those raised by neighbors on Milburn Avenue. Ms. Hahn explained that while the installation of a prior water containment system had helped reduce flooding along Milburn Avenue, portions of the field behind her property and along Milburn still experience significant flooding. Ms. Hahn noted that the land was never fully leveled after construction, and standing water frequently collects behind her property line, sometimes deep enough for ducks to swim. Ms. Hahn asked how the proposed stormwater system would address the existing drainage conditions and whether it would adequately manage the persistent water accumulation. Planning & Zoning Commission Meeting —August 14, 2025 PZ-07-25, PZ-10-25 10 Chairman Donnelly asked the petitioner and the petitioner's consultants to comeback to the podium to respond to the concerns raised by the residents. Chairman Donnelly asked the petitioner to respond to the question regarding fencing and screening around the athletic track. Ms. Moon stated that no fence is proposed around the athletic track and field. Instead, the design intends to use shrubs and bushes to maintain transparency and allow community access for walking and exercise when the school is not using the facility so no fence is proposed. Ms. Moon deferred to the project's landscape architect, Steve Gregory, for details. Mr. Gregory explained that, consistent with the ordinance, shrub screening will be provided along Can Dota Avenue and Lincoln Street, but without a fence, treating the frontage more like a front yard than a rear yard to preserve openness. Mr. Gregory noted the plantings will be clustered and approximately three to four feet in height, providing the required 50%screening. Mr. Gregory further stated that the team is seeking relief from the ordinance's 50/50 evergreen -to -deciduous ratio, proposing instead a 70/30 mix because evergreens perform poorly near pavements subject to salt spray. Aside from that ratio adjustment, Mr. Gregory stated that the project meets the screening requirement. Chairman Donnelly asked the petitioner to respond to concerns raised regarding lighting. Ms. Moon explained that a photometric plan was submitted showing that light levels at the property line will be zero. Ms. Moon emphasized that the intent is to minimize lighting overall, with only a few pole -mounted fixtures along the fire lane and at building entries for security purposes. Ms. Moon noted that all fixtures are designed to provide downward -directed illumination for security and general building safety, with no spotlights or outward glare. Ms. Moon reiterated that the photometric plan confirms compliance with the requirement of zero light spillover at the property line. Chairman Donnelly asked the petitioner to respond to concerns regarding construction traffic and on - street parking along Milburn Avenue. Mr. Papanicholas explained that, as with other large projects completed in the Village, a site logistics plan and a traffic management plan will be prepared and these will identify truck routes, contractor parking locations, and procedures for high -demand days. Mr. Papanicholas emphasized that the construction team will actively coordinate with staff, remain on -site daily, and implement wayfinding signage to ensure contractors and deliveries use the proper access points. Chairman Donnelly asked for confirmation that full-time contractors would be required to parkwithin the fenced construction site. Mr. Papanicholas confirmed this and stated that construction staff would not be permitted to use neighborhood streets for parking. Vice Chairman Beattie added that residents were concerned about contractors using narrow pedestrian pathways from Milburn Avenue or We Go Trail to access the site. Mr. Papanicholas responded that this practice will be expressly prohibited, signage will be posted as appropriate, and all contractors and delivery personnel will be instructed accordingly. Mr. Papanicholas further stated that violations would be addressed immediately, and repeated issues could result in police involvement if necessary. Chairman Donnelly invited testimony from Jeff Geltmeyer, project engineer with Eriksson Engineering, regarding flooding concerns. Mr. Geltmeyer explained that the existing underground infrastructure in the area is part of the Village's combined sewer system, which was not designed to function as a stormwater management system. Mr. Geltmeyer noted that the proposed project includes a new below -grade detention system sized to accommodate the 100-year, 24-hour storm event in compliance with MWRD standards. This system will be located along the northern frontage near Milburn Avenue, making use of the Planning & Zoning Commission Meeting —August 14, 2025 PZ-07-25, PZ-10-25 11 site's natural low point. Mr. Geltmeyer emphasized that the new school will represent an improvement, as the existing site lacks dedicated stormwater detention and currently discharges runoff directly into Village sewers. Chairman Donnelly confirmed that the design will account for all stormwater generated by the site, except for areas encumbered by existing Village -owned infrastructure. Mr. Geltmeyer clarified that the project will not add runoff to those areas and, in fact, will reduce flows to the sanitary sewer system, resulting in overall improvement to local drainage. Vice Chairman Beattie summarized that the project will add stormwater storage capacity, thereby helping alleviate the localized flooding concerns raised by residents. Mr. Geltmeyer agreed, stating that the new system will capture and store water underground instead of allowing it to pond in backyards. Discussion then turned to site circulation. Vice Chairman Beattie asked about bus traffic and potential congestion during student drop-off and pick-up. Ms. Moon responded that all bus operations will occur in the north parking lot accessed from Can Dota Avenue, with no left turns permitted, while parent drop-offs will use the south parking lot accessed from Lincoln Street. Ms. Moon explained that this separation was intentional to keep bus and parent traffic distinct and that adequate stacking capacity has been provided on -site for both buses and cars. Chairman Donnelly confirmed that the north lot will accommodate nine buses. Commissioner Olsen asked for clarification, and Ms. Moon reiterated that buses and parent traffic would be routed separately, with the building itself serving as a buffer between the two circulation areas. Commissioner Olsen also asked about construction hours. Mr. Papanicholas confirmed that all work will comply with Village ordinances and normal work hours. Mr. Papanicholas noted that the final summer of construction, which involves demolition of the existing school, will be intensive, but all workwill remain within allowed hours. Mr. Papanicholas also assured the Commission that street sweepers and redundant cleaning services would be used to keep neighborhood streets clean throughout the project. Hearing no further comments or questions, Chairman Donnelly closed the hearing and asked for two motions on the petitions. Chairman Donnelly requested a first motion to approve the final plat, Zoning Case No. PZ-10-25, to consolidate all of the subject properties, and a second motion to approve the conditional use subject to the conditions listed in the staff report. Commissioner Beattie made a motion and Commissioner Szymczak seconded the motions to approve the following: "Motion to approve: 1. Afinal plat of subdivision titled "Lincoln Consolidation", Case No. PZ-10-25; 2. A development code exception from Sections 15.401(B) and 15.402(B) to exempt the easement area over the Village's sanitary overflow system located at the west end of the site from counting towards the entire site; 3. A conditional use for a preliminary and final planned unit development to construct a 127,000- square-foot middle school, and complete related site improvements at 700 and 804 West Lincoln Street, Case No. PZ-07-25, subject to the conditions listed in the staff report."
