Both basins are tributary to the Wheaton Sanitary District’s Southside Interceptor sewer. The major components of the plan are listed below: Reduce excess flow infiltration in the sanitary system through public/private sector rehabilitation Add capacity to the public sanitary system to convey wastewater to the Southside Interceptor. In September 2015, the City Council authorized an amendment for engineering services on the Sanitary Sewer Capacity Assurance Program with RJN Group Inc. The amendment revised the scope for engineering services to create a joint study with the Wheaton Sanitary District to determine the existing sanitary sewer flows to the Southside Interceptor. The goal of the study was to determine if the recently upsized Southside Interceptor could accept additional flow from Basins 3 and 4, RJN subsequently performed flow monitoring on the Southside Interceptor and the basins tributary to the Southside Interceptor from the fall of 2015 through the spring of 2016. One major finding of the flow monitoring was that during a relatively small (8-month) storm event on May 12, 2016, the Southside Interceptor could not convey all wastewater to the treatment plant resulting in backup and overflows. This event provided documentation that even though the larger Southside Interceptor has additional capacity, the limited capacity of the treatment plant restricts flow from the Southside Interceptor. This finding indicates that the Southside Interceptor cannot accept additional flows from Basins 3 & 4. RJN also modeled the Southside Interceptor using the observed results to determine options for meeting the City Council’s goal of eliminating backups and overflows during a 10-year storm event. RJN will present the results of their flow monitoring and modeling work at the January 23 City Council Planning Session, with the final report detailing the specifics being available next month. Staff is seeking City Council direction to perform a preliminary engineering study to further investigate the options identified in RJN’s presentation for improvements to reduce backups and overflows in Basin 3 and 4.

Redman, P.E. Director of Engineering ç To: The Honorable Mayor and City Council Date: January 18, 2017 Subject: Residential Street Speed Limits Background Over the course of the past several months, the City Council received residential street speed feedback from concerned residents during Coffee with Council sessions, Council Meetings and in other forrris. In general, these residents would like residential speed limits lowered to reduce the driving speed on city streets, particularly through neighborhoods. In many instances, different groups of residents suggested lowering the residential speed limit as a method to improve safety for pedestrians and children. Education on the topic of lower speed limits may help the community understand the issue better, and allow the City Council sufficient background to make an infonned decision as how to proceed. Providing Information Staff completed a solicitation process that resulted in the selection of a traffic engineering consultant — KLOA, Inc to provide the City Council with an informational presentation on — residential speed limits at the January 23 Council Planning Session. KLOA specializes in residential/neighborhood and community-wide traffic studies. They are a very experienced traffic engineering and transportation planning firm with 22 years of experience in the Chicago region, and are very familiar with Wheaton having performed numerous traffic studies for both the City and private entities. KLOA’s presentation will cover speed limit legal and engineering practices, traffic signage and other traffic calming measures, enforcement strategies, options for setting speed limits, and expectations of lowering speed limits. KLOA will also be available to answer City Council questions. The Way Ahead Following the presentation and discussion, staff would be interested in the Council’s general sense of whether addressing residential speed limits is necessary. Should the City Council desire to further pursue a reduction in the current established residential speed limit or employ other alternatives such as increased enforcement strategies, the staff would further detail the necessary steps and costs for implementation in a follow-up report.

MEMORANDUM TO: Record FROM: Susan Bishel, Public Relations Coordinator SUBJECT: Jan. 23, 2017 City Council Planning Session Minutes DATE: Jan. 24, 2017 CC: Mayor and City Council, City Manager, City Clerk, Department Heads The Planning Session took place in the Council Chambers, Wheaton City Hall, 303 W. Wesley St., Wheaton, Illinois. Those attending the Planning Session included: Mayor Gresk, Councilwoman Fitch, Councilman Prendiville, Councilman Rutledge, Councilman Saline, Councilman Scalzo and Councilman Suess. Also in attendance were City Manager Dzugan, Assistant City Manager Duguay, Director of Public Works Laoang, Director of Engineering Redman, Chief of Police Volpe and Public Relations Coordinator Bishel. The session began at 7:00 p.m. and concluded at 9:30 p.m. The following items were discussed: I. Call to Order The Wheaton City Council Planning Session was called to order at 7:00 p.m. by Mayor Gresk. II. Approval of January 9, 2017 Planning Session Minutes The Council approved the January 9, 2017 Planning Session Minutes. III. Public Comment There were no public comments. IV. Residential Street Speed Limits City Manager Dzugan stated in response to resident requests, the City is exploring the possibility of changing residential street speed limits from 30 mph to 25 mph. Through a selection process, the City selected KLOA Traffic Engineers to assist the City in exploring this issue. Michael Werthmann of KLOA Traffic Engineers presented information to the City Council summarizing the laws that mandate speed limits, traffic studies, and how to set appropriate speed limits for different types of streets. Mr. Werthmann stated finding the ideal speed limit involves striking a balance between how fast people expect to drive in a given area and the protection of drivers, pedestrians and bicyclists. Traffic engineers use 85th percentile speeds – the speed at which 85% of drivers travel at or below on a particular street – to assist in setting speed limits. Mr. Werthmann stated lowering the speed limit below the 85th percentile speed can result in problems with conflicting speeds and driver frustration, as some drivers will follow the lower speed limit, while others will not. Mr. Werthmann stated the Illinois Vehicle Code allows municipalities to alter speed limits on the roads in their jurisdictions, but the code recommends these changes be based on traffic engineering studies and investigation in line with traffic engineering practices. The vehicle code recommends the studies include field investigation/observation and data collection. Speed limits can be adjusted based on factors such as locations with a high incidence of traffic accidents, pedestrian activity or on street parking. However, the IDOT Policy on Establishing & Posting Speed Limits only allows the prevailing speed to be reduced a maximum of 9 mph or 20 percent, whichever is less. In response to Council questions, Mr. Werthmann stated while traffic engineering studies are not mandatory to change speed limits, the Illinois Vehicle Code highly recommends them. He stated the City would also want to perform traffic studies for legal purposes related to enforcement. In response to questions about crosswalks, Chief Volpe stated Illinois law requires vehicles to stop if a pedestrian is in a marked crosswalk, and a separate law states pedestrians can’t enter a marked crosswalk until they can safely cross. In response to Council questions about bicyclists, Chief Volpe stated that when riding on the road, bicyclists must follow the same rules as other vehicles. Mr. Werthmann reviewed methods for calming traffic, including advisory signs, pavement markings, education and other physical and non-physical measures. He stated police enforcement is also generally effective, but it is expensive to continue enforcement efforts. In response to Council questions, Chief Volpe stated in most cases, officers will not write a ticket for drivers traveling less than 5 mph to 8 mph over the speed limit. If the City decides to lower the speed limit on residential streets, Chief Volpe stated the Police Department would start with educating residents, including a strong communication campaign, followed by a period of time during which officers issue warnings. In response to Council questions, Chief Volpe stated the Police Department has two speed trailers that display passing cars’ speeds and four speed signs that collect data on the speed of passing cars. He stated the trailers cost approximately $5,500 and are effective in educating drivers. Planning Session 1/23/17 2 In response to a Council question, Chief Volpe stated the Police Department does not currently have a program working with schools on pedestrian and bicycle safety. The Council requested that City staff provide further details about the necessary steps and costs for implementation in a follow-up report. V. Southside Interceptor Study/Model – Status To continue working toward the City Council’s priority of eliminating sanitary sewer backups and overflows during a 10-year rain event in Basins 3 and 4, the City has been working to reduce the amount of stormwater that enters the sanitary sewer system. The City also is working with RJN Group Inc. to determine if the Wheaton Sanitary District’s recently upsized Southside Interceptor could accept additional flow from Basins 3 and 4. Representatives from RJN Group reviewed the results of this study. Karol Giokas of RJN Group reviewed the Wet Weather Facility Plan the City and Wheaton Sanitary District created in 2006, which called for the City reducing the amount of flow to the Sanitary District, and both the City and the Wheaton Sanitary District upsizing some sanitary sewers. The Wheaton Sanitary District completed their Southside Interceptor project, and the City has been working in Basin 3 and 4 to reduce flow. Since completion of the Southside Interceptor, Ms. Giokas stated RJN performed flow metering to measure for peak flows, and the Wheaton Sanitary District has determined that the Southside Interceptor can’t take in the amount of flow that Basins 3 and 4 produce during a 10-year storm. In response to Council questions, Director of Engineering Redman stated that he does not believe the Wheaton Sanitary District has any plans to increase its plant capacity, and the Environmental Protection Agency would not be likely to allow a plant expansion because the EPA would want to first see work done to reduce flow during wet weather. In response to Council questions, Ms. Giokas confirmed that the flow levels are only a problem during wet weather, and the Wheaton Sanitary District plant can handle approximately 5 times its normal flow. Ms. Giokas reviewed the peak flow recorded during RJN’s flow metering, which showed significant restrictions on the system and caused problems for some locations in an 8-month storm event which occurred on May 12, 2016. Planning Session 1/23/17 3 City Manager Dzugan stated there is some difference between the modeling of when backups/overflows are predicted to occur versus actual backups/overflows. The model doesn’t show that some homes would not experience backups because they do not have basements, or if they have overhead sewers. Michael Young of RJN stated the original plan was for the City to upsize some sewers, which would reduce localized bottlenecks happening currently in Basin 4. However, the City needs to revise its plans now that it is known that the Southside Interceptor is unable to accept and carry the flow the City would be sending from Basin 3 and Basin 4. Mr. Young stated the options include reducing the flows, increasing the capacity, increasing system storage, and overhead sewers. One option would involve a 70% reduction in flow in Basins 3 and 4, which is estimated to cost $52 million to $57 million. A second option would be upsizing the sewer (like in the original plan), adding storage and doing some flow reduction. This is estimated to cost a total of $40 million, whereas the original plan was estimated to cost approximately $18 million. In response to Council questions about overhead sewers, Director of Engineering Redman stated while installing an overhead sewer will solve the immediate problem of backups in individual homes, it does not address the issue of excess flow and consequently backups in system. City Manager Dzugan recommended the City pursue a contract with RJN to pursue the next step and develop recommendations. VI. City Council/Staff Comments There were no City Council/Staff comments.

Also in attendance were City Manager Dzugan, Assistant City Manager Duguay, Director of Engineering Redman, Director of Finance Lehnhardt, Director of Public Works Laoang, and Public Relations Coordinator Bishel. The session began at 7:00 p.m. and concluded at 8:34 p.m. The following items were discussed: I. Call to Order The Wheaton City Council Planning Session was called to order at 7:00 p.m. by Mayor Gresk. II. Approval of Minutes — December 12. 2016 The Council approved the December 12, 2016 Planning Session Minutes. III Public Comment There were no putnts IV 2016-2019 Strategic Plan Up Assistant City Manager Duguay resented an update on the City s 2016-2019 Strategic Plan and progress City staff has made to,ard achieving set targets Regarding the first strategic priority of financial stability, Assistant City,Manager Duguay stated City staff are providing the Council with monthly financial report and are working on the draft budget for fiscal year 2017-2018. The Council will soon receive the staff’s 5-year financial forecast, and staff is working on finalizing new financial reporting that will allow City staff and the Council to view financial information through a new interface that will more easily display data and trends. City staff are also finalizing a Capital Improvement Plan, which identifies all City capital projects for the next five years, prioritizes the projects and plans for their funding. Assistant City Manager Duguay stated City staff will present the proposed Capital Improvement Plan to the City Council in February. For the second strategic priority, quality infrastructure, Assistant City Manager Duguay reviewed the status of work on the Downtown Streetscape Plan. CCS International Inc. assisted the City in developing an REP for a civil engineering firm to complete design drawings, specifications and construction oversight for Phase I of the plan. The City selected Primera in the bidding process, and work will begin this upcoming construction season. Assistant City Manager Duguay stated this process will also include a communications effort to inform the Downtown Wheaton Association, property owners and residents about Phase I work, which will affect Front Street. In response to Council questions, Assistant City Manager Duguay stated planning for Phase II will take place in the summer of 2018 and construction will occur in the summer of 2019. In response to Council questions City Manager Dzugan stated the City will meet with the Downtown Wheaton Association on a regular basis to keep local businesses informed and will also directly notify residents and affected businesses Assistant City Manager Duguay reviewed the status of the City’s program to elirninate backups and overflows in a 10-year rain event in Basin 3 and Basin 4 The City completed two pilot projects and measured their effect on flow into the sanitary sewer system In response to Council questions about areas downstream of Basins 3 and 4 Assistant City Manager Duguay stated the Council will be hearing an update from RJN on this suect at the next Planning Session. 4 In terms of the City’s goal of flood-protecting structures from overland flooding in flood-prone areas the City will continue working to complete studies of all 18 flood-prone areas In response to Council questions, Director of Engineering Redman stated the City must complete these studies to determine the cost-benefit analysis and properly prioritize projects. City Manager Dzugan stated the studies are also necessary for the City to apply for grants or other assistance. Because of studies the City has completed, the County purchased three flood-prone properties in the Williston area In response to Council questioiis, Director of Engineering Redman stated in comparison, some other communities are not doing anything to address flooding. Downers Grove is using a similar approach to Wheaton, and Downers Grove has completed studies of its flood-prone areas and prioritized projects to reduce flooding. The Council requested more information about how Downers Grove has financed improvements. In response to Council questions, City Manager Dzugan stated the studies are anticipated to be complete, including analysis, in 2021. 1/9/17 Planning Session 2 In response to a Council question, Director of Engineering Redman stated less than 1,000 homes are in these 18 flood-prone areas, and there are additional homes in the flood plain. Assistant City Manager Duguay stated another goal the City is working toward is identifying and documenting designed stormwater storage areas. In response to Council questions, Director of Engineering Redman stated the City does not have all of this information collected in one place, and there are likely more than 250 stormwater detention facilities. Due to the time-consuming process, City staff is proposing a change to this goal to identifying and documenting 25% of these areas. The next step would be making sure they are operating as designed. City Manager Dzugan suggested when City staff reaches this step, staff begins with structures built after 1991, as the City has original plans for these properties due?rnwater requirements enacted at this time. Assistant City Manager Duguay reviewed City ‘s work toward developing a comprehensive Capital Improvement Plan The plan has been completed, and City staff is finahzing its draft plan that it will present to the City Council in the near future. He stated the City CoUncil will also be presented with a proposed lead service line policy. Assistant City Manager Duguay stated City staff ‘is also working with all departments on goals toward providing efficient and effective services City departments are working to identify core services and collecting information o.n best practices and industry standards. The City is also looking for each department to identify areas where cost savings or efficiency can be improved. For example, the City’s Public Works Department is trying a new method of clearing cul-de-sacs that pushes snow into the center of the cul-de-sac. Director of Public Works Laoang stated about 60% of Wheaton’s cul-de-sacs can use this method, which reduces the amount of time to clear them. In response to Council questions about how the City notifies residents and businesses of work being done, Assistant City Manager Duguay stated the City uses door hangers and directly communicates with residents and businesses before work begins, and the City will be working to be more proactive in communicating upcoming projects. In response to Council questions about when the City will do another community survey, City Manager Dzugan stated it is standard to have a survey done about every 4 or 5 years, and the last survey was completed in 2014.
