Redman, P.E. Director of Engineering To: The Honorable Mayor and City Council Date: December 8, 2016 Subject: Sanitary Sewer Lateral Rehabilitation — Pilot Project II Attached to this memorandum is a report prepared by the Engineering Department describing the findings on sanitary sewer lateral rehabilitation for Pilot Project II and a comparison of the two pilot projects performed by contract sewer lining of sewer service laterals in Basin 4. Both projects utilized the same rehabilitation process cured-in-place lining of the existing sewer lateral - - pipes. In Pilot Project I, laterals were selected in two sub-basins by high flow per sewer main segment, and lateral rehabilitation was performed from the sewer main to within 5-10 feet of the building. In Pilot Project II, a single sub-basin was selected where all sewer laterals were rehabilitated from the sewer main to the right-of-way/private property line, with few exceptions for newer or rear yard laterals. Pre- and post-rehabilitation flow monitoring was perfonried in both pilot project areas to quantitatively assess excess flow reduction from the lateral rehabilitation. Staffs comparison of the two pilot projects indicated the following: • Pilot II was a more constructible method of reducing excess flow from private properties. • Pilot II required less resident involvement and was completed more efficiently. • Pilot I was more cost effective per rate of excess flow removed due to selective rehabilitation of high flow laterals. Staff recommends continuing sewer lateral rehabilitation as a method of reaching targeted excess flow reductions in Basin 4 and Basin 3. We recommend a process which combines the lessons learned from both pilot projects lateral rehabilitation from the main to the right-of-way/property line and the initial — selection of high flow sewer main segments. We believe that this “hybrid” process will result in the best cost per rate of excess flow removed and be the most constructible with less resident inconvenience. Staff is also considering evaluating less expensive methods for lateral rehabilitation such as grouting lateral pipes to seal cracks and joints. Grouting may cost about 10% of the cost of lining, but has no structural benefits and has a shorter life-expectancy. The pilot projects comparison is only part of the plan for sanitary sewer capacity improvements to minimize sewer overflows and basement backups. RJN Group is completing its final report on the Southside Interceptor capacity analysis and modeling which will provide a bigger picture of what can be accomplished to address capacity improvements for Basin 4 and Basin 3. Staff anticipates a presentation of the Southside Interceptor report early next year.  City of Wheaton 303 W. Wesley Street Wheaton, IL 601 87-0727 630-260-2000 City of Wheaton, Illinois wwwwheaton.iLus To: Paul Redman From: Russell Peacock Date: December 6, 2016 Subject: Service Lateral Rehabilitation Pilot II in Comparison to Pilot I Background In 2006, the City and Wheaton Sanitary District jointly created a Wet Weather Facility Plan. The plan identified priority areas tributary to the Wheaton Sanitary District based upon flow rates in the sewer system during wet-weather conditions. Flow reduction and capital improvement projects were identified at a conceptual level to achieve mutually agreeable flow reduction targets. RJN Group was then engaged to establish concrete plans to reduce backups and overflows. The System Recommendation Report, submitted by RJN Group in 2011, explained the majority of excess flow in Basin 4 was coming from private sector sources. The largest contributors to excess flow included foundation drains and service laterals. RJN Group recommended a pilot project (Pilot 1) to test both public and private sector flow reduction methods. The methods of flow reduction tested included private sector source removal (service lateral rehabilitation and remediation of building violations) and public sector improvements (manhole and sewer main rehabilitation), as shown in Table 1. Table 1: Flow Sources to be Removed Percent of Total Cumulative Quantity Percent Source to be Flow Flow Flow Sources of Defects of Flow Removed Removed Removed 283 2 220% 2 2% Pr - 2 L .. 88 1% 20 1% SJpPLrnps 21% 100% 11% 1C53 01 2E Drurs 22 0% 0% RJN Group presented the results from Pilot I in the Assessment and Recommendations report, dated 2014, which evaluated the private property excess flow reduction methods tested. The original flow reduction target for Pilot I was 40%. Based on the data collection and analysis, RJN Group estimated that Pilot I resulted in a 31% flow reduction for a 1-Yr, 1-Hr storm event. Approximately 25% of the flow reduction came from service lateral rehabilitation (utilizing cured-in-place pipe lining as the rehabilitation method), 4% from sump pump disconnection, and 2% from other flow reduction methods. At the time of flow metering, not all building violations had been corrected, therefore reducing the anticipated flow reduction from sump pump disconnections from 11% to 4%. Analysis performed incorporating additional flow data collected after the completion of Pilot I resulted in a revised flow reduction estimate of 37%. Wheaton City Hall 303 W.

Dzugan — — City Council — Suzanne Fitch John Prendiville iohn Rutledge W. Thoreson Saline Todd Scalzo - - - Phil Suess At the conclusion of Pilot I, staff recommended implementation of another project to apply lessons learned from Pilot I and the results from a similar community (Wauwatosa, WI) performing service lateral rehabilitation. Wauwatosa found the majority of excess flow reduction was achieved by rehabilitation of the portion of the service lateral in the right-of-way while rehabilitating the service lateral from the property line to the home had minimal impact on flow reduction. The subsequent project (Pilot II) used this information to create a more cost-effective and constructible approach to service lateral rehabilitation. Activities and Findings Sub-basin 4-8 was selected for Pilot II due to characteristics of the sewer system and area. The sub-basin contains 120 buildings which are predominantly single family homes. The project scope included rehabilitating all non-PVC service laterals excluding those connected to backyard sewer mains (due to accessibility issues), capping improperly abandoned service laterals, and installing connection seals as needed. Table 2 compares the details of Pilot I and Pilot II. Table 2.

Both project areas required point repairs on 10% of the service laterals prior to rehabilitation. Pilot I required the contractor to locate 30% of all service laterals from the home, which involved substantial homeowner cooperation. Pilot II was designed to rehabilitate only to the private property line and did not include the pipe between the property line and the home which was the major source of project delays during Pilot I. Pilot II required only 5% of service laterals to be located from the home which minimized construction delays. RJN Group flow monitored the sub-basin before and after service lateral rehabilitation and after analysis concluded that during a 1-Yr, 1-Hr storm event, 40% excess flow reduction was achieved. When the flow reduction is applied to the pre-rehabilitation flow of 1.3 million gallons per day (mgd) or an average of 7 gprnlproperty for a 1-Yr, 1-Hr storm event, it indicates a total sub-basin excess flow reduction of 0.5 mgd (4 gpm/property for each of the service laterals rehabilitated) in Pilot 11. Post-rehabiliation flow in sub-basin 4-8 is still 0.8 mgd, (an average of 4 gprn!property) for a 1-Yr, 1-Hr storm event. Analysis The results of Pilot I indicate a larger flow reduction per service lateral rehabilitated than the results of Pilot II. The higher flow reduction per service lateral rehabilitated in Pilot I is perceived to be the result of strategic selection of rehabilitation locations based on excess flow measurements. The pre-rehabilitation excess flow in the sewer system has been measured with dye flooding and is proportional to the service lateral conditions and the location relative to the storrnwater system. Pilot II resulted in flow removal costs 40% higher than Pilot I, as shown in Figure 1. Some of this cost increase is due to the unit costs for Pilot II coming in approximately 20% higher than Pilot 1. It is assumed the price differential was due to underbidding by the contractor for Pilot I and the costs for future service lateral rehabilitation will be in line with the unit prices of Pilot II. If the increased prices are added to Figure 2 it will add approximately $200/gprn removed to the cost of Pilot I. $2,500 $2,000 $1,500 E E $1,000 $500 $0 Basin 4 Recommendations Pilot I Result Pilot II Result Report Estimate Figure 1. Cost per Ho Removed There are an estimated 2400 additional service laterals in Basin 3 and 4 that are candidates for rehabilitation. To achieve the excess flow reduction goal of 40% in basins 3 and 4 utilizing only service lateral rehabilitation between the sewer main and the property line, an additional 1200 service laterals will require rehabilitation (using excess flow reduction results from Pilot II). The estimated cost of rehabilitating 1200 service laterals is $10 million. This cost does not include any capacity improvement or the $2.4 million spent on flow reduction to date. Conclusions Pilot II used the lessons learned from Pilot I and the results from Wauwatosa to design and a more cost effective and constructible approach to service lateral rehabilitation. The project rehabilitated 77 service laterals in sub-basin 4-8 in addition to capping abandon service laterals and installing connection seals. Data analyzed by RJN Group showed an excess flow reduction of 40% in Pilot II. This flow reduction indicates a larger flow reduction per service lateral rehabilitated in Pilot I than Pilot II. The higher flow reduction per service lateral in Pilot I is attributed to performing service lateral rehabilitation on select sewer main segments with the highest excess flow rates. The pre-rehabilitation flow in basins 3 and 4 is equivalent to 5.6 gpmlproperty, as shown in Figure 2, for a 1- Yr, 1-Hr storm event. To achieve the 40% excess flow removal goal, an additional 1200 service laterals (out of 2400 possible) require service lateral rehabilitation between the sewer main and the property line. The cost to achieve this flow reduction goal is $10 million in addition to the $2.4 million already spent on the pilot projects. Capacity improvement will then be needed to convey or store the difference between the post- rehabilitation flow and the existing maximum discharge capacity. Furthermore, Figure 2 displays excess flow for a 1-Yr, 1-Hr storm but current goals will require the conveyance or storage of a 10-Yr storm. 6 Flow Reduction > from Rehabilitation of Additional 1200 o5 Service Laterals Ci DI riiot ($10 Million Est.)

The results from Pilot I in comparison to the results from Pilot II indicate that selective rehabilitation can maximize the excess flow reduction by concentrating on the sewer mains with the highest excess flow rates. It is recommended that future service lateral rehabilitation occur between the sewer main and the property line, as done in Pilot II, while only rehabilitating the service laterals on select sewer main segments, as done in Pilot 1, to maximize the excess flow reduction while minimizing costs.  einoranduin Michael G. 11 Dzuga Ciey M’anager TO: The Honorable Mayor & City Council DATE: December 9, 2016 SUBJECT: Park Avenue Traffic Report Please find attached a memorandum from the Director of Engineering detailing a traffic analysis that was completed by the City’s Engineering Department for Park Avenue between Naperville Road and Main Street. The analysis was undertaken in response to resident concerns expressed at the June 11, 2016 Coffee with Council meeting. The residents expressed concerns regarding excessive speeds given the geometry and existing infrastructure along this segment of Park Avenue, potential conflict between pedestrians and vehicles, and excessive pass through traffic. The City did work with DuPage County to establish a no left turn prohibition from northbound Naperville Road at Park Avenue. The City adopted the necessary ordinance establishing the left- hand turn prohibition in early fall. At our Planning Session, Mr. Redman will review the data collected and provide a more detailed review of lowering the speed limit, mitigating efforts to reduce pass through traffic and installation of a sidewalk. Mr. Redman recommends as the most irnpactful adjustment being the construction of a public sidewalk along at least one side of Park Avenue from Naperville Road to Main Street. The current budget includes funding of $75,000 for construction of new sidewalks under a 50/50 cost share program (total costs split between city and residents). Although this program has been available for the last 5 years, the City has not had any one take advantage of it. The staff is considering proposing a different New Sidewalk Program as part of the 20 17-2018 fiscal year budget. The details of a New Sidewalk Program are still to be ironed out; however, I felt it important to communicate staffs intention as you consider the traffic analysis. Attachment Memorandum Paul G. Redman. P.E. A Director of Engineering To: Michael G. Dzugan, City Manager Date: November 10, 2016 Subject: Park Avenue between Naperville Road and Main Street Residents of the 100-200 block of East Park Avenue have requested that the City address traffic and pedestrian safety along Park Avenue between Naperville Road and Main Street. The residents have requested that the City enforce a lower speed limit and/or restrict the volume of pass-through vehicle trips along Park Avenue to improve pedestrian safety. East Park Avenue between Naperville Road and Main Street is a city residential street without curbs and sidewalks. The street is approximately 1,250 feet in length with a horizontal reverse-S curve, and a change in vertical grade of 34 feet from Naperville Road to Main Street. Parking is allowed on both sides of the street, except for the south side between Main Street and Gamon Road. The Engineering Department has collected traffic data on three separate dates to obtain traffic volumes and vehicle speeds along East Park Avenue. The average traffic volume was 488 vehicles per day. The predominate flow of traffic is eastbound along Park Avenue. The traffic volume is not considered excessive for a local residential street, but considering Park Avenue is a short street segment between a City collector street and a County arterial street, with only 25 homes, it appears to be carrying many pass- through vehicles. Motorists are possibly avoiding a delay at the traffic signal at Roosevelt Road and Naperville Road in both the east-to-south and north-to-west directions. Vehicle speed limits measured do not reflect a speed problem, but the measurements do not consider the perception of vehicles traveling a narrow curvilinear street, changing lanes to pass a parked vehicle, and pedestrians in the street. The 85 th percentile speed was measured between 27 and 29 mph in all cases which is below the legal speed limit of 30 mph for residential streets. There is a curve warning sign with advisory speed of 15 mph; however, this is recommended and not an enforceable speed limit. The residents have provided suggestions to the City to improve safety along Park Avenue. These suggestions include lowering the posted legal speed limit, reduce the volume of pass-through vehicles, and/or install public sidewalks. The memo will address each of these suggestions. Lower Posted Speed Limit The City may lower the legal speed limit if an engineering study supports findings that a lower speed limit isjustified. The L5 g hl percentile speed and certain physical constraints of the street (narrowness, lack of sidewalks, no curbs, and number of driveways) are factored in support of a lower speed limit. There are certain issues that Staff and the City Council should consider prior to lowering the speed limit. Lowering speed limits on a street-by-street basis would not be a good practice due to the lack of uniformity city wide and the amount of time needed to perform the engineering studies for each street considered. Also, additional speed limit signs throughout the city, that are not presently necessary, will be necessary to provide legal notice to motorists of the differing speed limits from one street to the next. It may be more appropriate for the City Council to consider a City-wide “residential street” or “neighborhood street” speed limit of 25 mph. A fuller report of the pros and cons of altering speed limits on residential streets may be completed with the assistance of a qualified traffic engineering consultant with experience in speed reduction studies for residential applications. The most prevalent misconception on the public’s part regarding posting lower speed limits is that lower speed limits will lower the actual speed motorists drive. Many studies have not conclusively found this result. Reduce Pass-through Traffic Volume The City may limit pass-though vehicle trips by restricting certain access to or turns from Park Avenue at Naperville Road and/or at Main Street. The City has already passed an ordinance restricting northbound Naperville Road left-turns onto Park Avenue. Further access/turn restrictions may be proposed such as from southbound Main Street at Park Avenue or from eastbound Park Avenue at Naperville Road to limit pass-through trips from east-to-south. It should be noted that an turn restriction will also affect Park Avenue residents. Access restrictions may consequently relocate the pass-through trips and local trips from Park Avenue to the surrounding residential street network. Changing motorist behavior with the use of posting access/turn restrictions is not 100% and some Police enforcement will be necessary to reinforce behavioral change. Sidewalks Pedestrian safety may be enhanced along Park Avenue with the installation of a public sidewalk along at least one side of Park Avenue from Naperville Road to Main Street. Providing for pedestrian access along a separate pathway arid away from the roadway would be a fair safety improvement for Park Avenue. However, there are some physical constraints with a sidewalk installation along Park Avenue due to the grades of the parkways, and the extensive amount of private landscaping and trees present along both parkways. Preliminary review by Engineering staff assesses a sidewalk project for Park Avenue as more difficult and expensive due to the physical limitations noted. Recommendation A careful consideration regarding any of the potential changes described in this memorandum for Park Avenue should be made by the City Council as other city residents have similar concerns regarding safety along their residential streets. Also, discouraging the use of Park Avenue for pass-through trips may have unintended consequences for its neighboring residential streets diverted pass-through traffic. — Only one of the suggestions above may be necessary to improve safety along Park Avenue to the residents’ satisfaction. Both suggestions of lowering the posted speed limit and posting access/turn restriction signs require a motorist to change their behavior without consequences. Police enforcement may assist obeisance, but the police cairnot always be present. Installing public sidewalks may be the best improvement of the three suggestions, as he residents will not have to walk in the street.

Also in attendance were City Manager Dzugan, Assistant City Manager Duguay, Director of Engineering Redman, Director of Planning & Economic Development Kozik, Director of Finance Lehnhardt, Director of Public Works Laoang, Project Engineer Peacock and Public Relations Coordinator Bishel. The session began at 7:10 p.m. following the conclusion of a public hearing and concluded at 8:15 p.m. The following items were discussed: I. Call to Order The Wheaton City Council Planning Session was called to order at 7:10 p.m. by Mayor Gresk. II. Approval of Nov. 28, 2016 Planning Session Minutes The Council approved the Nov. 28, 2016 Planning Session Minutes. III. Public Comment Bill Fowee, 804 Gamon, encouraged the City Council to add sidewalks along Park Avenue between Naperville Road and Main Street to improve safety. He stated the City could consider lowering residential street speed limits to 25 mph like Naperville, but he expressed concern that it might not make much difference if drivers continue to exceed the posted speed limit. Violet Deal, 103 E. Park Ave., stated she observes traffic increase on Park Avenue from approximately 6:30-8:00 a.m. and in the late afternoon, as many drivers use it as a cut-through street to avoid traffic. She has concerns about the safety of drivers pulling out of their driveways in this area and stated she is not sure that just installing sidewalks would solve the problems in this section of Park Avenue. Roberta Stewart, 109 E. Park Ave., asked when the speed limit for residential streets was changed from 25 mph to 30 mph. She suggested the City consider using a temporary barrier at one end of Park Avenue to see if this would reduce the number of vehicles using Park Avenue as a cut-through street. Dan Fitzpatrick, 252 E. Park Ave., stated he frequently walks from his home to the train station and is concerned for his safety and that of other pedestrians on Park Avenue. He spoke in favor of adding sidewalks on Park Avenue. IV. Park Avenue Traffic Analysis Director of Engineering Redman reviewed the City’s traffic analysis for Park Avenue between Naperville Road and Main Street. Residents requested this study due to safety concerns. The analysis involved collecting traffic data on three occasions. While the results showed traffic volumes were not excessive for a local street, the data does not take into account that it’s a short street segment, it has an S curve, and it intersects with a County arterial road. The speed readings also did not show excessive speeding, however Director of Engineering Redman stated this does not take into account the road characteristics and that there are no sidewalks. The Engineering Department looked at three possible ways to address safety concerns: lowering the speed limit, taking steps to reduce pass-through traffic, and/or adding sidewalks. Director of Engineering Redman stated the speed limit for residential streets has been 30 mph for at least the past few decades. He expressed concern with lowering the speed limit for only one street segment. This could set a precedent requiring the City to perform traffic studies for each segment of roadway where a lower speed limit is requested, which would not be practical for City staff. The Council could consider a City-wide change for residential streets, and the Engineering Department will be selecting a consultant to look at this issue and present it to the City Council. Director of Engineering Redman reviewed the actions already taken to reduce pass-through traffic, including prohibiting left-hand turns onto Park Avenue from Naperville Road. The City could place other restrictions on traffic movement onto Park Avenue. However, this could create an inconvenience for residents who live in this area, and it could redistribute cut-through traffic to another local street. Another option would be for the City to add sidewalks on one side of Park Avenue. Director of Engineering Redman stated Park Avenue does have some physical issues that would make it more difficult to install than an average street, but it would be possible. 12/12/16 Planning Session 2 In response to Council questions, Director of Engineering Redman stated the traffic study used devices that measure the speed of passing cars, and there can be some erroneous readings. In response to another question, Director of Engineering Redman stated if sidewalks are added, the City typically has to address issues such as trees or private landscaping planted in the public right-of-way. To answer Council questions about the traffic counts for this street segment, Director of Engineering Redman stated the study periods showed a low traffic volume for 24 hours, though there were some peak times in traffic. He stated temporarily blocking off access to part of Park Avenue would be difficult because the City would need to capture traffic data for the entire neighborhood to measure the impact. In response to a Council question about the intersection of Elm and Naperville Road, Director of Engineering Redman stated that stoplight is controlled by DuPage County. City Manager Dzugan stated the only program the City currently has regarding new sidewalks is a shared cost program, where the property owners and City split the cost 50-50. City staff recommends the Council consider a new sidewalk program fully funded by the City. The City could use funds budgeted for the shared cost program plus sidewalk funds that developers are required to pay the City when new developments are added. In response to a Council question, Director of Engineering Redman stated the only grant funding that might be available for this project is the federal Safe Routes to School program. Council members expressed interest in considering a new sidewalk program that would prioritize school walking routes and analyzing current speed limits on residential streets. V. Pilot II Service Lateral Rehabilitation City Manager Dzugan stated the City’s rehabilitation of service laterals is one tool the City is using to reduce sanitary sewer backups and overflows. Director of Engineering Redman stated the City completed a second pilot project lining service laterals to homes and compared it to the results of the first pilot project. In Pilot I, the City chose service laterals in two sub-basins with the highest flow readings per sewer main segment and rehabilitated from the sewer main to within 5-10 feet of the building. In Pilot II, the City chose a single sub-basin and rehabilitated all sewer laterals from the sewer main to the right-of-way or private property line. The results showed that Pilot II was better at reducing flow, but Pilot I was more cost-effective per flow. 12/12/16 Planning Session 3 City staff is recommending a process combining the two methods in which the City chooses high-flow areas and rehabilitates the main to the property line. The City will also look at a different repair method. Director of Engineering Redman stated RJN will have a report for the City in January with a bigger picture of how to reduce overflows and backups in Basin 3 and 4. In response to a Council question about the projected costs of this project, Director of Engineering Redman stated to reach the City’s goal of a 40% reduction in flow, it would cost approximately $10 million to complete this work in Basin 3 and Basin 4. In response to Council questions about why lining laterals to the property line is effective, Director of Engineering Redman stated this part of the line is deepest in the ground, and groundwater affects it more than the portions closer to buildings. Also, a lot of infiltration is caused by the crossing of the lateral with other infrastructure, and this is in the right-of-way. To address a question about how Wheaton ranks in flow compared with other communities, City Manager Dzugan stated there is not information available on other communities, because Wheaton is a leader in this area. To explain the process the City uses to identify high-flow areas, Director of Engineering Redman stated the City uses dyed water to flood an area of ground and then uses video cameras in the sanitary sewers to see where this groundwater is entering the sanitary sewers.
