Residents have an expectation that their streets will be safe and pleasant. When they perceive this to be the case, the quality of life is enhanced. However, when the negative issues that can be associated with traffic intrude into their neighborhoods, residents' sense of community and personal well -being are diminished. Concerns of excessive speeding, cut - through traffic and pedestrian safety in neighborhoods are often expressed by residents to the Village. A belief in a diminished quality of life and feeling of safety by residents as a result of the unwelcome traffic press the Village to provide solutions. The Village of Mount Prospect's Neighborhood Traffic Calming Program incorporates education, enforcement and engineering solutions to the traffic issues that exist within our neighborhoods. It builds upon the recently completed Neighborhood Traffic Study that has resulted in a consistent pattern of intersection traffic control and speed limits to enhance driver expectation and safety. The Institute of Transportation Engineers defines traffic calming as "the combination of mainly physical measures that reduce the negative effects of motor vehicle use, alter driver behavior and improve conditions for non - motorized street users." Using this definition as a framework, the program will provide a process to develop appropriate solutions and will include the cooperative efforts of Village Staff, elected officials, residents, business owners and road users to achieve our desired goals. Village of Mount Prospect Neighborhood Traffic Calming Program GOALS The goals of the Neighborhood Traffic Calming Program are: + Enhance neighborhood safety and livability by reducing excessive speeding and traffic volumes on residential streets. + Encourage reasonable and responsible driver behavior through education and enforcement. + Leverage the data collected from the Neighborhood Traffic Study so that traffic calming projects can be pursued via either a resident - driven or Village- initiated process. Promote and enhance safety for bicycle and pedestrian travel. Foster a collaborative working relationship between Village Staff, elected officials, residents, business owners and road users in the development of traffic calming projects. + Make efficient use of Village resources including personnel and funding by following the established process of evaluating and prioritizing traffic calming requests. Village of Mount Prospect Neighborhood Traffic Calming Program .w� hT 3 POLICY STATEMENTS Residential Focus The Neighborhood Traffic Calming Program is focused on residential areas since a goal is to enhance neighborhood safety and livability. Only local residential and collector streets will be considered in this program. Arterial streets are specifically excluded from this program because the nature of arterial streets is to move large numbers of vehicles in a relatively free - flowing manner. Non - neighborhood traffic is encouraged to use arterial streets in order to reduce cut - through traffic in the neighborhoods. It is recognized, however, that vehicular, bicycle and pedestrian issues exist on arterial streets. Other means and resources outside the Neighborhood Traffic Calming Program will be explored to address these issues. Neighborhood participation is important in order to develop a consensus of the issues that adversely affect the neighborhood, evaluate the pros and cons of the various traffic calming measures, and ensure that the issues are adequately addressed. It is essential to consider a wide range of perspectives and observations in addition to engineering data. The program is designed so that residents can become actively involved in defining the problem(s) and in the decision - making process in order to have a sense of ownership in the outcome. In addition to neighborhood participation, it is important that the process reflects the opinions of a majority of the residents and not just a few vocal residents. This is implemented through the use of a petition that must be signed by at least 51% of the properties along the qualifying street to initiate the traffic calming process. The limits of the petition area will be determined by the Engineering Division. Within the established Project Area, at the end of the process, a final vote requiring a favorable response of a least 66% of the properties on a street is required to implement traffic calming measures on that particular street. This is further explained in the Traffic Calming Process section as well as the flowchart located in Appendix A. • Traffic calming measures will only be considered on local residential and collector streets. • Residents and business owners will be encouraged to participate in the identification of the traffic issues as well as development of the solution. • Traffic calming projects will require a positive response from at least 51% of the properties along the qualifying street to initiate the process and 66% of the properties along a street within the Project Area to support installation of traffic calming measures. Education and Enforcement Traffic calming measures physically alter the roadway and are considered permanent changes that will impact the behavior of motorists. These dramatic changes should only be considered after consideration of less costly options. Education provides the opportunity for the Engineering Division and Police Department to communicate their perspective to residents. The advantages and disadvantages of traffic calming measures, the purpose of traffic control devices (stop and yield signs), and the true extent of a problem based on collected data .can be shared with residents to make them better informed. This can be accomplished through telephone conversations, neighborhood meetings, open houses, brochures, the Village web site and newspaper media. In addition, employing education tools will allow residents to get involved in easing traffic concerns. One example is the placement of yard signs (Keep Kids Alive — Drive 25 campaign) in neighborhoods by residents in collaboration with the Police Department. Enforcement relies on the Police Department to be a presence in neighborhoods and enforce existing speed limit and traffic control ordinances. In addition to selective enforcement, the Police Department also will utilize the speed display trailer and drone vehicles to ease traffic concerns. Village of Mount Prospect Neighborhood Traffic Calming Program 4 Inexpensive engineering measures such as additional signage, striping and pavement markings will also be considered before approving traffic calming measures. Education, enforcement and inexpensive engineering solutions are to be considered prior to approval of any traffic calming measures. Minimum Criteria The Village receives requests on a regular basis for traffic calming measures. The primary complaints involve speeding vehicles or a high volume of vehicles relative to the street type. The extent of a problem on one street will be different than another street. Therefore, it is important to develop thresholds for streets to qualify for traffic calming measures. Otherwise, traffic calming measures could be installed on streets where there would be minimal effect on traffic speed and volume. Not only would this set a precedent to permit traffic calming measures on every neighborhood street, it would have a negative impact on efficiently using Staff resources and Village expenditures. Since traffic calming measures directly impact vehicular speed and volume, minimum speed or volume criteria will need to be met in order for a Project Area to qualify for traffic calming measures and begin the petition process. The only exception will be if the street has a recent history of crashes atypical for a neighborhood street and traffic calming measures would be the appropriate solution. The specifics of the minimum criteria are explained in Appendix B. di In order for a street to qualify for traffic calming measures and begin the petition process, minimum traffic volume or speed criteria are to be met. Project Areas The Village was segmented into eighteen (18) neighborhood zones as part of the Neighborhood Traffic Study, a program that reviewed the traffic control at all neighborhood intersections and speed limits on all neighborhood streets. Each neighborhood was reviewed as a whole rather than analyzing each intersection or street independently. By having a big picture focus, the Village was able to consider the potential impact throughout the neighborhood. And a product of the study was the collection of extensive vehicular volume and speed, pedestrian and intersection data. Both the traffic data collected from and approach to the Neighborhood Traffic Study are key aspects of the Neighborhood Traffic Calming Program. The traffic data collected from the Neighborhood Traffic Study will serve as the primary source to be able to identify streets with traffic conditions above the norm and that qualify for traffic calming measures. This will allow the Engineering Division to streamline the process by not having to always perform an initial traffic study. The type and level of the issue(s) can be assessed and a Project Area more quickly created. Further, potential traffic calming measures can begin to be discussed based on the traffic data and street characteristics. It will also be important to keep in mind that traffic calming measures on one street can have an impact on surrounding streets. A noticeable increase in vehicular volume or speed on an adjacent street may arise when the street in question is the sole focus of a project. In developing a solution for one traffic problem, it is important not to shift the problem to an adjacent street or neighborhood. Neighborhood street classifications and their respective functions are to be maintained. In an effort to address this concern, the Engineering Division will create a Project Area after a petition is received for traffic calming measures on a particular street. The boundaries of the Project Area will be the limits of potential significant impact should construction of traffic calming measures take place on the qualifying street. In some cases the Project Area will be limited to the qualifying street in question whereas in other cases it will include adjacent streets. Adjacent streets within the Project Area may or Village of Mount Prospect Neighborhood Traffic Calming Program & 5 may not meet the criteria for traffic calming measures when evaluated independently, and may or may not receive approval for traffic calming measures, but may be considered in the development of a project should the Engineering Division believe traffic calming measures on the qualifying street in question will significantly impact traffic conditions on other streets in the neighborhood. A Project Area, therefore, does not necessarily include the entire neighborhood allowing for the possibility of multiple Project Areas within a neighborhood. + The traffic data collected from the Neighborhood Traffic Study will serve as the primary source to identify streets that qualify for traffic calming measures. + The type and level of the traffic issue(s) along with the street characteristics will help determine the appropriate traffic calming measures. • Traffic calming projects are intended to minimize diverted traffic to other local residential or collector streets. • A Project Area, the limits of potential significant impact should construction of traffic calming measures take place on the qualifying street, will be created for each potential traffic calming project. Resident and Village Initiated Processes Residential streets with traffic conditions above the norm are not necessarily considered hazardous where traffic calming measures are required. In many cases, residents may consider traffic calming measures too intrusive and would prefer impermanent solutions such as enforcement and education. There is not always the need to aggressively respond to traffic data when to residents the current conditions do not significantly affect their livability. Two processes, therefore, have been developed for the Neighborhood Traffic Calming Program. The resident - initiated process allows the neighborhood to reach out to the Village when it believes conditions have reached a level for pursuing traffic calming measures. This process provides a sense of ownership to improve the livability in the neighborhood. Once this process is initiated, the Village will partner with residents to develop a traffic calming project. The petition form to initiate the process is located in Appendix C. The Village- initiated process allows the Engineering Division to pursue traffic calming measures when a hazardous condition is clearly evident. A high crash rate, recorded speeds well above a typical residential street, and recorded volumes excessive for the street classification are examples. The process will permit the Engineering Division to bypass the petition process but still allows for resident involvement in the plan development phase. Resident - initiated and Village- initiated processes have been developed to pursue traffic calming projects. Project Prioritization The need to prioritize projects arises when the demand for traffic calming measures exceeds Village resources. This includes Village Staff time to work on a project as well as construction funding. A common approach to efficiently utilize Village resources is to prioritize projects so that neighborhoods with the greater problems are addressed first. Since most neighborhood traffic problems involve speeding vehicles or a high volume of vehicles relative to the street type, these are the first factors taken into consideration. Another factor that will be considered in defining the extent of the problem is the recent crash history along the street. In addition, the amount of pedestrian activity within the neighborhood will be taken into account. Neighborhoods that have a higher number of pedestrian generators such as parks and schools will be impacted greater than those neighborhoods without pedestrian generators. Due to the high concentration of school -aged pedestrians and localized traffic congestion associated with elementary, middle and high schools, these pedestrian generators are weighted double that of other non - school Village of Mount Prospect Neighborhood Traffic Calming Program N 6 pedestrian generators. And a final factor to be considered is the presence (or lack) of sidewalk. In neighborhoods without sidewalk, pedestrians are in greater conflict with vehicles than in neighborhoods with sidewalk. Should the Village receive multiple requests for traffic calming projects, the Engineering Division will prioritize them utilizing the Project Prioritization Worksheet located in Appendix D. The one street within the Project Area that receives the most points will represent the Project Area during the prioritization review. * Traffic calming studies will be prioritized based on the extent of the problem. Traffic Calming Measures There are a few basic categories of traffic calming measures. Each one can have a different effect on motorists as well as bicyclists and pedestrians. It is, therefore, important to understand how each traffic calming measure functions and the primary traffic issue each that one is intended to address. The library or "toolbox" of traffic calming measures will provide the Engineering Division with a number of alternatives when developing a project. The identified traffic issue(s), collected traffic data, street classification, street geometries, adjacent land use and cost are some of the factors that will be considered to determine the appropriate traffic calming measure(s) for each project. Brief descriptions of the different types of traffic calming measures are provided here. The toolbox is located in Appendix E and provides detailed descriptions of each of the traffic calming measures. Horizontal deflection measures include traffic circles and chicanes. Constriction measures include choke points and midblock medians. These measures slow traffic by physically forcing motorists to maneuver around the measures. The use of landscaping within these devices not only enhance the aesthetics of the streetscape but also can break up the motorist's line of sight thereby reducing the comfortable speed of travel. When used in conjunction with one another, these measures are effective for a longer stretch of roadway rather than just in the immediate vicinity of the measure. These measures also tend to have relatively lower impacts on emergency vehicles. However, use of these measures usually requires prohibition of on- street parking adjacent to the measure. Horizontal deflection measures and constriction measures such as traffic circles, chicanes, choke points and midblock medians are acceptable traffic calming measures. Vertical deflection measures include speed humps, speed tables and raised crosswalks. These measures slow traffic by physically forcing motorists to maneuver over the measures. They are typically 14 to 22 feet long and 3 to 4 inches high. In order to be effective for a long stretch of roadway, they must be installed every 250 -400 feet. Otherwise, many motorists will speed between measures in order to "make up for lost time ". Speed humps can also have a negative impact on emergency vehicle response time as well as maintenance activities such as snow plowing and street sweeping. Their use can also redistribute traffic in a neighborhood as motorists may choose alternate routes to avoid them. For these reasons, vertical deflection measures are to be limited in their application. Their use is to address defined speeding problems and should only be considered when other traffic calming measures may not provide effective results. Primary emergency vehicle response routes and collector streets are not eligible for vertical deflection measures. This is because it is not only imperative that emergency vehicles not be hindered while responding to an emergency but just as important that the outcome not result in a significant redistribution of traffic within a neighborhood. To this end, adjacent streets may be included in a Project Area should vertical deflection measures be considered for a local street. Traffic calming measures may or may not be installed on adjacent streets but it is important to consider their potential impact during the process. Village of Mount Prospect Neighborhood Traffic Calming Program 7 Vertical deflection measures such as speed humps, speed tables and raised crosswalks are acceptable traffic calming measures in limited applications. Pedestrian safety measures include curb extensions and pedestrian refuges. These measures are usually installed near high pedestrian areas such as schools and parks. The primary purpose of these measures is to make it safer for pedestrians to cross the street. Curb extensions narrow the street at a key crossing point minimizing the distance and time a pedestrian is in the street. Pedestrian refuges provide a place of safety for pedestrians along the center of the street allowing them to cross one direction at a time. A secondary benefit of these measures is that they can slow traffic as vehicles pass the measure. Pedestrian safety measures such as curb extensions and pedestrian refuges are acceptable traffic calming measures. Volume reducing measures include diverters, intersection median barriers, street closures and turn restrictions. These measures alter the existing transportation circulation system. As a result, these measures can have impacts that would need to be evaluated in greater scope than just along one particular street. While they can be a viable solution to a street problem, it is important not to shift the problem to an adjacent street or neighborhood. Volume reducing measures such as diverters, intersection median barriers, street closures and turn restrictions are acceptable traffic calming measures if it can be verified through quantitative analysis that a substantial amount of cut through traffic is evident. However, they should be evaluated as part of an area -wide study if their use is to be considered. Stop signs are not traffic calming measures. Residents, however, often request stop signs in an effort to calm traffic. Although residents believe that stop signs will reduce vehicular speeds, traffic studies have shown there is little difference with vehicular speeds at the midblock whether there is or is not a stop sign at the adjacent intersection. In some cases, vehicular speeds after the vehicle has passed through the stop controlled intersection have shown to be higher than without a stop sign as motorists try to "make up for lost time" after the stop sign. Inappropriate use of stop signs can also create significant negative impact to emergency vehicles. Emergency vehicles are required to verify that a stop controlled intersection is clear of vehicles prior to entering. Many times this means that the emergency vehicle must nearly come to a stop. Stop signs are traffic control devices that should be used when appropriate to assign right -of -way to conflicting traffic movements, not to calm traffic. Stop signs should be installed only at locations where conditions meet criteria established in the Manual on Uniform Traffic Control Devices. Unwarranted stop signs can have a high violation rate, create disrespect at other stop controlled intersections and create a false sense of security for other road users and pedestrians. + Unwarranted stop signs are not to be used as part of the program. Emergency Response A critical concern about the use of traffic calming measures is the delay they may create for fire engines, ambulances and law enforcement vehicles. It is important to be aware of the trade -offs when making decisions about the use of traffic calming devices. The more aggressive measures for slowing traffic will slow emergency response as well. Recognizing the importance of emergency response time, all traffic calming measures will be designed to minimize the impact on emergency vehicles. Since many collector streets are considered primary Village of Mount Prospect Neighborhood Traffic Calming Program I S8 emergency vehicle response routes, particular attention must be paid to the types of measures used on collector streets. Measures that considerably interfere with emergency vehicle operations on collector streets or other primary emergency vehicle response routes will not be allowed. A map identifying the Village's primary emergency vehicle response routes is located in Appendix F. Traffic calming measures shall be designed to minimize the impact on emergency vehicle response times. Traffic calming measures shall be limited on primary emergency vehicle response routes. + The Fire Department and Police Department shall be involved in the process and be given the opportunity to provide input prior to approval of any traffic calming measures. Maintenance Many traffic calming measures alter the geometry of the roadway. Poorly designed measures could interfere with maintenance activities such as street sweeping, leaf pick -up and snow plowing. This could have a negative effect on the appearance of the neighborhood and the residents' quality of life. • Traffic calming measures shall be designed to minimize the impact on maintenance activities such as street sweeping, leaf pick -up and snow plowing. • The Public Works Department shall be involved in the process and be given the opportunity to provide input prior to approval of any traffic calming measures. Funding The Village's Traffic Improvement Account will be the primary source to fund traffic calming projects. Grant resources such as Safe Route to Schools and the Illinois Transportation Enhancement Program will also be explored to offset Village costs. All costs associated with traffic calming projects will be paid for by the Village. Residents and businesses will not be required to directly share in the costs. Such funding is subject to availability. Administration costs including Village Staff time to collect and analyze data, prioritize requests, conduct neighborhood meetings, develop engineering drawings detailing the traffic calming measures, and perform any post- studies after construction will be covered under the normal operating budget and will not be the responsibility of residents or businesses to fund. If a project goes to construction, the Village will cover the costs of the bidding process, construction inspection and project management. All construction costs will also be paid for by the Village. Maintenance of the traffic calming measures will be necessary on a regular basis after construction. The Village will be responsible for maintenance such as replacing damaged signs, refreshing striping and pavement markings, pavement repair and landscaping. Maintenance of the traffic calming measures will be done at no direct cost to residents or businesses. Residents and business owners within a Project Area will not be required to directly fund any portion of a traffic calming project or future maintenance of such measures. All costs will be paid for by the Village. Removal Although there are many policies and steps incorporated in the program to avoid the scenario whereby a neighborhood requests to have traffic calming measures removed, it is acknowledged that this may occur. In order for consideration to remove traffic calming measures from an individual street or entire Project Area that were installed via the resident - initiated process, a petition must be submitted to the Village. If the request is for an individual street that did not originally qualify for traffic calming measures when Village of Mount Prospect �t 9 Neighborhood Traffic Calming Program �i evaluated independently, the petition must be signed by at least 66% of the properties along the street in question. If the request is for an individual street that did originally qualify for traffic calming measures or is for an entire Project Area, the petition must be signed by at least 66% of the properties within the Project Area. A petition cannot be submitted for at least one year after installation of traffic calming measures in order to avoid a premature reaction to their effectiveness. Should the Village receive a petition, a neighborhood meeting will be held to discuss the issues and impacts of removal of the traffic calming measures. As part of the discussion, residents and businesses will be presented the latest traffic data to understand the effectiveness of the existing traffic calming measures. They will also be informed that any costs associated with removing the traffic calming measures will be paid for by the Village. The Village will then send a ballot to the affected properties within the Project Area detailing the removal request. If the request is for an individual street that did not originally qualify for traffic calming measures, ballots will only be sent to the properties along the street in question. If the request is for an individual street that did originally qualify for traffic calming measures or is for an entire Project Area, ballots will be sent to all properties within the Project Area. A deadline for return will be shown on the ballot. In order to proceed with removal of the traffic calming measures, a positive response from at least 66% of the properties involved must be received by the deadline. No response or a late response will be counted as opposition to the removal. Should there be sufficient support to remove the traffic calming measures, the Village Board of Trustees will be advised and requested to make a final decision based on a simple majority vote. Removal of the traffic calming measures will not take place unless the Village Board of Trustees approves the removal and until funds are allocated by the Village. Similar to the petition process, single family properties and single use properties such as schools, parks, churches, commercial businesses, etc. will count equally as a single vote. Each unit within small scale multi - family properties without a management company such as condominium complexes will also have a single vote. The same will be for small scale commercial properties. For large scale multi - family residential properties such as apartment complexes or large scale multi -unit commercial properties, the management company will decide and be allotted votes equaling the number of buildings on the property. For such large scale properties without a management company, each unit will be counted that proportion of the number of buildings divided by the number of total units on the property. For traffic calming measures installed via the Village- initiated process, only the Village can initiate the process for removal. Typically, the Village will initiate the removal process should the street be altered, adjacent land use change, or other situations arise where it is determined the traffic calming measures are no longer effective or necessary. A traffic study must support the recommendation to remove such traffic calming measures. After a neighborhood meeting, a survey will be sent to the Project Area soliciting feedback. Resident comments will be forwarded to the Village Board of Trustees and taken into account before they make a final decision based on a simple majority vote. • Traffic calming measures shall remain in -place for a minimum of one year before being considered for removal. • Removal of a traffic calming measure installed via the resident- initiated process shall require a positive response from at least 66% of the affected properties within the Project Area and approval by the Village Board of Trustees. • Removal of a traffic calming measure installed via the Village- initiated process shall only be initiated by the Village and must be approved by the Village Board of Trustees. Village of Mount Prospect Neighborhood Traffic Calming Program TRAFFIC CALMING PROCESS Neighborhood Focus Most traffic calming programs in the country are set up to be reactive, resident - initiated. That is, a resident or group of residents petition the local government for traffic calming measures on a particular street and staff responds to the request. Typically, a process is in place to determine whether the street qualifies for traffic calming measures and if so what steps must be taken in order to receive approval. Two advantages to this approach are that 1) public interest has been generated early on in the process and 2) overstretched staffs' keep the project scope limited to the street in question. However, a major disadvantage to this approach is that solving one problem on a particular street may have repercussions on surrounding streets and throughout the neighborhood. That is why a new trend in traffic calming programs is emerging. The Neighborhood Traffic Study was established to review intersection traffic control and speed limits on a neighborhood -wide basis. This comprehensive approach was created to assure that consistent decisions would be made and the neighborhood as a whole would operate safely. And based on the results of our post- studies, this neighborhood -wide approach is achieving our goal of improving safety. Along this same line of thinking, the Village supports a traffic calming program that involves an area -wide approach to best serve the community. Similar to installing a stop sign at one intersection without giving thought to the impact on the adjacent intersection, constructing traffic calming measures on one street without considering the impact on the adjacent street(s) may create new problems. Initial Work As part of the Neighborhood Traffic Study, eighteen (18) neighborhood zones were created to manage the study and implementation phases. After implementing the approved sign changes, post- studies were then performed to determine the effects on the neighborhoods. With the post- studies, the Engineering Division has been able to collect extensive vehicular volume and speed data including average daily traffic, peak hour volume, average speeds and 85 percentile speeds on the neighborhood streets. It is from this data that we have been able to identify streets that experience traffic conditions above the norm. One of the first steps in the development of this traffic calming process involved the Engineering Division's review of the post -study data on a neighborhood by neighborhood basis in order to identify individual streets that would qualify for traffic calming based on the established minimum criteria. Maps for each neighborhood zone highlighting those streets that currently qualify for traffic calming have been developed based on the post -study vehicular volume and speed data. These maps will be continually updated to reflect the most current information as additional traffic studies are performed and more data gathered in the future. Resident- Initiated Process Establishing minimum criteria and identifying streets that qualify for traffic calming allows the program to focus on the most problematic streets. When the Village receives a traffic complaint and traffic calming maybe a solution, the first step will be to determine whether the street in question qualifies for traffic calming. If the Engineering Division believes updated traffic data is necessary then it will be collected and compared to the established guidelines. Otherwise, the Engineering Division will rely on the latest post -study data gathered during the Neighborhood Traffic Study. If the street does not qualify for traffic calming, the Engineering Division will consider less intrusive solutions such as: • education resources • selective speed limit / intersection traffic control enforcement Village of Mount Prospect Neighborhood Traffic Calming Program ._ 11 * use of the speed display trailer * use of a Police Department drone vehicle * improving sight distance at intersections * appropriate additional signing, striping or pavement markings The resident or group will then be notified and the issue referred to the Police Department. Similar to current practice, the Police Department will schedule an enforcement period as time permits. This will not only include actual speed limit or stop sign enforcement but use of the speed display trailer and a drone vehicle to improve compliance of the traffic regulations. Education tools such as Keep Kids Alive — Drive 25 signs and on -site conversations with residents are other options that will continue to be offered. And as technology further develops, additional measures may be considered by the Police Department. Should the street meet any of the established criterions for traffic calming, the Engineering Division will then determine whether there is support from the neighborhood to consider a traffic calming project. This will be done through a petition form provided by the Village. The petition form will provide space for residents to describe their traffic concerns and obtain signatures. One advantage to this step is that getting public support early in the process should help the Village to work with the neighborhood to address its concerns. Another advantage is that the traffic concerns described in the petition will help the Engineering Division determine the appropriate traffic calming measure(s). If the petition is returned to the Village with signatures from at least 51% of the properties along the street, the Village will then determine a timetable for formal review. Single family properties and single use properties such as schools, parks, churches, commercial businesses, etc. will count as one (1). Each unit within small scale multi - family properties without a management company such as condominium complexes will also count as one (1) as will small scale commercial properties. For large scale multi- family residential properties such as apartment complexes or large scale multi -unit commercial properties, only the management company can sign the petition with its signature counted as being equivalent to the number of buildings on the property. For such large scale properties without a management company, each unit can sign the petition with the signature to be counted that proportion of the number of buildings divided by the number of total units on the property. If there are multiple petitions received by the Village for different streets, they will be prioritized based on the severity of the issue. Each year, the top projects on the priority list will be selected for study that year, depending upon the availability of funding. When it is time to begin plan preparation, the Engineering Division will first create a Project Area around the qualifying street in question. The boundaries will depend on the location of the qualifying street, its characteristics, and the type and level of the traffic issue(s). Once a Project Area has been created, the Engineering Division will take reasonable steps to notify those properties within the area that preliminary plans are being prepared at the request of the neighborhood. This will include sending a notification to persons who own property within the Project Area but may not live within the area. Should the Project Area include adjacent streets beyond the qualifying street in question, the notification will be sent to all affected properties including those on the adjacent streets. The notification will explain the process to be followed by Staff. It will also include a list of traffic calming measures being considered by the Engineering Division to address the identified traffic issues. Residents will be given the opportunity to share their traffic concerns with the Engineering Division and choose their preferred traffic calming measure(s) via e-mail, regular mail or the telephone. The notification will also indicate the planned Transportation Safety Commission Meeting date and refer residents to a project web page on the Village web site to keep the public apprised of the project's progress. And lastly, residents will be given the opportunity to provide the Village an e -mail address that can be used for future correspondence. This will allow the Engineering Division to stay in close contact with those most interested in the project and to minimize the number of mailings resulting in a more efficient and economical process. Village of :Mount Prospect Neighborhood Traffic Calming Program T12 The Engineering Division will next prepare preliminary plans for the Project Area. Resident and property owner feedback will be taken into account during plan development. Village departments including Police, Fire and Public Works will next review the plans and provide comments. The plans will then be refined based on the received comments. The recommended plan will then be presented to the Transportation Safety Commission at a regular meeting. Those residents within the Project Area who provided an e -mail address will be reminded of the meeting. The project web page will also be updated to allow residents to view the recommended plan as well as provide public notice of the meeting. The Village will present the recommended plan and residents will be given the opportunity to comment. The Transportation Safety Commission's objective will be to decide on the elements of a plan, not to decide on the need for traffic calming measures. The Commission will consider both the Engineering Division's proposal and comments from the public in order to make a recommendation that addresses the identified traffic issues. At the end of the meeting, the Transportation Safety Commission will either vote on a plan or direct the Engineering Division to make revisions and bring it back for further discussion at another meeting. At this stage, the goal is for the Engineering Division to satisfy the conditions of the Transportation Safety Commission and receive Commission support for a plan. Once this is achieved, the Engineering Division will mail a ballot to the properties along those streets within the Project Area that have recommended traffic calming measures included in the plan. A deadline for return will be shown on the ballot. No response or a late response will be counted as opposition to the plan. Should traffic calming measures be recommended on adjacent streets in addition to the qualifying street in question, each street will be tallied independent from one another. A favorable response of a least 66% of the properties on a street will be required to continue in the process to construct traffic calming measures on that particular street. This may result in streets being omitted from the project should they not achieve the minimum support required. However, if none of the qualifying streets within the Project Area satisfy the minimum support required then traffic calming measures will not be approved on any of the streets within the Project Area regardless of the results on the other streets. Similar to the petition process, single family properties and single use properties such as schools, parks, churches, commercial businesses, etc. will count equally as a single vote. Each unit within small scale multi - family properties without a management company such as condominium complexes will also have a single vote. The same will be for small scale commercial properties. For large scale multi - family residential properties such as apartment complexes or large scale multi -unit commercial properties, the management company will decide and be allotted votes equaling the number of buildings on the property. For such large scale properties without a management company, each unit's vote will be counted that proportion of the number of buildings divided by the number of total units on the property. The ballot mailing will also encourage residents to check the project web page for vote results and state the Village Board Meeting scheduled for Village Board consideration of the plan should the residents support a traffic calming project. Residents will once again be given the opportunity to provide the Village an e -mail address that can be used for future correspondence. If the plan is not supported by those within the Project Area, residents will be notified via e-mail and the project web page will be updated to show the vote results. Residents within the Project Area will then have a 30 -day period to file a request with the Village to have the plan forwarded to the Village Board of Trustees for a final decision. If a request is made within the timeframe and it is agreed the plan will be heard, an extraordinary vote as defined in the Village Code by the Village Board of Trustees will be required to approve the project. In addition, the Transportation Safety Commission can also decide to forward the plan to the Village Board of Trustees for a final decision. Again, an extraordinary vote by the Village Board of Trustees will be required to approve the project. Village of Mount Prospect Neighborhood Traffic Calming Program _.», �V ]13 If the plan is not forwarded to the Village Board of Trustees, less intrusive education, enforcement and engineering measures as described earlier in this section will be considered in lieu of traffic calming measures. Another petition for traffic calming measures within the same Project Area cannot be submitted for at least one year after the original vote deadline. Further, the petition will require signatures from at least 66% of the properties along the qualifying street in order to begin the process again. Should the plan approved by the Transportation Safety Commission be supported by those within the Project Area, it will then be presented to the Village Board of Trustees. Again, those residents within the Project Area who provided an e -mail address will be notified of the meeting. The project web page will also be updated to show the vote results and provide public notice of the meeting. Once Village Staff presents the plan, the results of the vote, and any comments received from the public, the Village Board of Trustees may approve the plan by a simple majority vote, direct the Engineering Division to make revisions and bring it back for further discussion, deny the plan, or take such other action as it deems appropriate. Should a plan be approved, final construction drawings will be developed and the project will be scheduled for construction once funds are allocated by the Village. Any street within the Project Area that did not obtain enough resident support and acquire traffic calming measures cannot petition the Village again for at least one year after project completion. Such a petition will require signatures from at least 66% of the properties along the street in question in order to begin the process again. Should a plan ultimately be denied by the Village Board of Trustees, less intrusive education, enforcement and engineering measures will be considered as described earlier in this section. Another petition for traffic calming measures within the same Project Area cannot be submitted for at least one year after the Village Board of Trustees' decision. Such a petition will require signatures from at least 66% of the properties along the qualifying street in order to begin the process again. At such time the Engineering Division determines reasonable after completion of the project, a post -study will be performed to determine its effectiveness and to determine if any additional action is necessary. The findings will be included in a report to the Village Board of Trustees, Transportation Safety Commission and appropriate Staff. Interested residents within the Project Area will be notified via e-mail and the report will be posted on the project web page. As necessary, additional traffic studies may be performed to determine if the traffic calming measures continue to achieve the desired goals. Village- Initiated Process The process as explained above is resident - initiated coupled with a significant amount of up -front work performed by the Engineering Division. This allows the Village to regulate the number of potential projects while providing an avenue for residents to get involved early in the process. Doing this up -front work will also afford the Village the opportunity to identify a street that requires immediate attention. Factors including a high crash rate, recorded speeds well above a typical residential street, and recorded volumes excessive for the street classification may cause the Village to initiate a project rather than wait for resident interest. This may require greater effort in generating resident support at the beginning of the process but will be necessary if the Village identifies a hazardous condition. The course of action to be undertaken will be similar to the resident - initiated process but will be initiated by the Village rather than residents. One other difference is that the recommended plan or variation supported by the Transportation Safety Commission will still be presented to the Village Board of Trustees regardless of resident support. Rather than having a final resident vote, a survey will be sent to the Project Area soliciting feedback. Resident comments will be forwarded to the Village Board of Trustees for its consideration before a final decision. A simple majority vote by the Village Board of Trustees will be required to approve the project.

( )ti1xxt 1 1 "i Village of Mount Prospect Neighborhood Traffic Calming Program MA 061= MINIMUM CRITERIA The Engineering Division has collected extensive vehicular volume and speed data including average daily traffic, peak hour volume, average speeds and 85 "' percentile speeds on most neighborhood streets as part of the Neighborhood Traffic Study. If updated traffic data is necessary before deciding whether a street qualifies for traffic calming measures, the Engineering Division will perform a traffic study. Otherwise, the Engineering Division will rely on the data collected from the Neighborhood Traffic Study. For a street to qualify for traffic calming measures and begin the petition process, at least one of the criteria thresholds below must be met. Speed* + The average speed is at least 5 mph above the speed limit The 85`' percentile speed is at least 9 mph above the speed limit Volume ** • The average daily traffic is at least 1000 vehicles • The peak hour volume is at least 120 vehicles * the 20 mph school speed limit is to be used along streets adjacent to schools, when applicable signs are in place, and when enhancing pedestrian safety is a primary goal; in all other cases the standard posted speed limit for the street is to be used ** applies only to collector streets adjacent to high pedestrian generator facilities (schools, churches, parks, etc.) and local streets Should an individual street qualify for traffic calming measures, the Engineering Division will also identify any surrounding streets that may be significantly impacted by traffic calming measures on the street in question. The selected surrounding streets may not meet the minimum criteria but could be adversely impacted if not considered in the development of a traffic calming project. The boundaries of potential significant impact will define the Project Area. The only exception to meeting any of the criteria thresholds is if the street has a recent history of crashes atypical for a neighborhood street and traffic calming measures are the appropriate solution. Should the Engineering Division identify a high crash rate for the street, the Village has the discretion to initiate development of a traffic calming project even if none of the vehicular volume or speed criterions are met. In analyzing the crash reports for a street with a recent history of crashes, the Engineering Division will first consider less intrusive education, enforcement and engineering measures. If it is determined traffic calming measures are the appropriate solution, the Engineering Division will begin the Village- initiated process as described on page 13. Definitions These definitions pertain to the criteria thresholds described above and apply to an engineering traffic study typically lasting between 48 and 72 hours. average speed — The mean speed, in miles per hour, of all vehicles during the traffic study. It is typically measured at the midblock of the street. 85"' percentile speed — The speed, in miles per hour, at which 85% of all vehicles during the traffic study are traveling at or below. It is typically measured at the midblock of the street and represents the basis for establishing the speed limit. average daily traffic — The number of vehicles, measured in both directions, passing a point along the street during a 24 -hour period. It is calculated by dividing the total number of recorded vehicles by the number of days in the traffic study. peak hour volume — The highest number of vehicles, measured in both directions, passing a point along the street during any 1 -hour period during the traffic study. Appendix C — Petition Form 1 1? Director Sean P. Dorsey Mount Prospect Public Works Department 1700 W. Central Road, Mount Prospect, Illinois 60056 -2229 TRAFFIC CALMING PETITION FORM Deputy Director Jason H. Leib Pursuant to the guidelines set forth in the Neighborhood Traffic Calming Program, in order for the Village to consider a traffic calming project, the person/group making the request must obtain signatures from at least 51 % of those properties directly impacted by the request. The attached map indicates those properties. Based on the _ properties, a minimum of _ signatures is required. Note that only one (1) signature will be counted for each property. The person/group making the request must make all effort to notify every property. Once everyone directly impacted by the request has been notified and the minimum number of signatures has been obtained, the petition form is to be returned to the Public Works Department. Once the petition has been processed, the Village will then notify everyone in the project area of the next steps. A description of the traffic concerns will assist the Village in developing a solution.

Village of Mount Prospect Neighborhood Traffic Calming Program E1 TRAFFIC CALMING TOOLBOX This toolbox was developed to provide guidance on the use of various traffic calming measures acceptable in the Village of Mount Prospect. It is intended to be used in conjunction with the overall Neighborhood Traffic Calming Program that outlines the goals, policies and processes for addressing traffic concerns in the Village. Each page provides the following information for different traffic calming measures: Description An illustration and written description is provided for each measure. Application Each traffic calming measure is designed to address specific traffic issues. The application section outlines the common uses for each measure. Advantages Each measure in the toolbox provides some advantages to traffic calming and to the quality of life in the neighborhood. The advantages section outlines the positive impacts associated with each traffic calming measure. Disadvantages Although each measure included in the toolbox provides some positive aspects to traffic calming, each has negative impacts as well. The disadvantages are outlined so that tools can be evaluated for both their positive and negative effects. Variations There are often several variations of specific traffic calming measures. Several of these are provided where they are appropriate. Special Considerations This section offers a variety of issues that should be considered for each traffic calming measure. Emergency response and operational concerns are flagged in this section. Cost The cost section is intended as a general guide to costs using low, moderate and high designations for the different measures. Village of Mount Prospect Neighborhood Traffic Calming Program E2 Traffic Calming Measures Not Used in the Program Stop signs are not traffic calming measures. They are traffic control devices that assign right -of -way to conflicting traffic movements at intersections. They are not to be used for speed control. Traffic studies have shown there is little difference with vehicle speeds at the midblock whether there is or is not a stop sign at the adjacent intersection. In some cases, vehicular speeds after the vehicle has passed through an unwarranted stop controlled intersection are as high, and occasionally higher, than without a stop sign, as motorists try to "make up lost time" at the stop sign. Stop signs should be installed only at locations where conditions meet criteria established in the Manual on Uniform Traffic Control Devices. Unwarranted stop signs can have a high violation rate, create disrespect at other stop controlled intersections and create a false sense of security for other road users and pedestrians. Children at Play signs are commonly requested in neighborhoods. However, they are not standard traffic control devices and have not been found to be effective in improving the safety of children. Residential areas commonly have children and the presence of these signs does not necessarily have a long -term effect on driver behavior. The Village's policy is that such signs will only be installed adjacent to parks where there is an expectation on the driver's part to see a concentration of children playing. Village of Mount Prospect Neighborhood Traffic Calming Program E3 Traffic Calming Measures Used in the Program Education Enforcement Signing & Striping Horizontal Deflection Measures • Traffic Circle • Chicane Constriction Measures • Choke Point • Midblock Median Vertical Deflection Measures* • Speed Hump • Speed Table / Raised Crosswalk Pedestrian Safety Measures • Curb Extension • Pedestrian Refuge Volume Reducing Measures* • Diverter • Intersection Median Barrier • Street Closure • Turn Restriction Vertical deflection and volume reducing measures can alter the existing transportation circulation system. As a result, these measures have impacts that would need to be evaluated in greater scope than just along one particular street. While they can be a viable solution to a street problem, it is important not to shift the problem to an adjacent street or neighborhood. Careful consideration must be taken before using vertical deflection or volume reducing measures.
