CITY HALL – COUNCIL CHAMBERS CONFERENCE ROOM MINUTES I. ROLL CALL/CALL TO ORDER Chairman Cathy Waldeck called the meeting to order at 5:00 p.m. Aldermen Michelle Moreno, Timothy Newman, and Standford Tack were present. Staff in attendance included Michael Thomas, Director of Public Works; Bob Kiely, City Manager; Bob Ells, Superintendent of Engineering; Dan Martin, Superintendent of Public Works; Cathy Czerniak, Director of Community Development; Jim Lockefeer, Management Intern; and Eileen Timken, Management Analyst. Also in attendance was James Dudek, ComEd, and Patrick Graves, ComEd. II. APPROVAL OF THE MARCH 7, 2016 PUBLIC WORKS COMMITTEE MEETING MINUTES Alderman Moreno moved to approve the March 7, 2016 Public Works Committee meeting minutes. Alderman Newman seconded the motion, which carried unanimously. III. UPDATE ON COM-ED’S STREET LIGHT L.E.D. CONVERSION PROJECT Superintendent Martin stated that ComEd recently begun a Smart-Ready LED Street Lighting Program with the initial objective of replacing all of the bulbs in the 88 ComEd owned street lights throughout the City. However, there were concerns previously noted by the Committee regarding the brightness of the LED lights. Therefore, it was determined that further research needed to be completed before implementing the LED replacement project. Mr. Martin continued explaining that Lake Bluff and Barrington have implemented the Smart-Read LED Street Lighting Program. Staff went to Barrington to survey the recently installed LED lights. The survey concluded that the LED lights currently available through the LED replacement project are brighter than the street lights installed in Lake Forest. The lowest dimming setting on the LED lights currently available is 50 watts, which is the equivalent of a 100 watt halo light. James Dudek commented that the parallel described by Mr. Martin was accurate. He also stated that the LED light grid and the Smart Meters need to be installed before dimming options are available to municipalities. Alderman Newman asked for clarification regarding the technology available for dimming. Patrick Graves responded explaining that dimming technology exists; however, it is necessary that further research is completed regarding the dissemination of the dimming technology for municipalities. Alderman Newman then asked if the City pays for street light electricity. City Manager Kiely responded that the City does pay for the street light electricity. Alderman Moreno then inquired about feedback received regarding the LED lights. Patrick Public Works Committee Meeting – May 16, 2016 Page 2 of 8 Graves responded referencing the LED replacement project implemented in Lake Bluff, where 200 LED lights were installed and 6 complaints were received regarding intensity levels. He noted that some LED lights appear to be brighter than others, such as in the case of Lake Bluff, if the light pole is slanted. Shields are available for LED lights if the intensity of the brightness is a concern. Mr. Martin explained that ComEd will continue to develop best practices for the Smart-Read LED Street Lighting Program. When the dimming options become available, staff will be in communication with ComEd. Alderman Moreno asked for clarification regarding the expected timeline for the LED replacement project implementation. Patrick Graves responded that it is expected that the LED replacement project will be implemented in Lake Forest in the fall. Specific dates will be provided by ComEd in the late summer. He continued stating that there is a strong interest in municipalities having increased control of the LED light brightness. IV. APPROVAL OF A RESOLUTION APPROVING AN EXCEPTION FOR PROPERTY LOCATED AT 1590 N. WAUKEGAN ROAD WITH RESPECT TO THE WATER METER CUSTOMER CLASSIFICATION Director Thomas reviewed the approval of a Resolution granting an exception from the standard water meter customer classification for the property located at 1590 N. Waukegan Road with City Council on March 7, 2016. City Council responded by requesting alternative solutions to modifying the City Code. Director Czerniak responded to this request by developing a Resolution proposing that the water meter billing system classification for 1590 N. Waukegan Road is changed from the “Large Customer Class” to the “Medium Customer Class”. Therefore, a 2” water meter base rate will be charged, rather than a 6” water meter base rate. Director Czerniak explained that this change could result in a significant savings per quarter for the homeowners of 1590 N. Waukegan Road. Alderman Newman asked if this Resolution would set a precedent for other residences with similar circumstances. Director Thomas responded that staff have been researching this concern. Properties with similar circumstances have not been identified, though. Director Czerniak explained that the Resolution presents some very specific findings regarding the exceptional exclusivity of this situation, so as to not set a precedent. Alderman Moreno asked if risk can be limited by explicitly defining the limiting parameters of this specific situation. Director Czerniak responded that the Resolution makes an effort to do that. Specific conditions related to 1590 N. Waukegan Road and addressed by the Resolution would be very difficult for other properties to meet. City Manager Kiely noted the complexity of this issue and explained that the Public Works Committee and staff would request the approval of the Resolution at the City Council meeting on June 6, 2016. Public Works Committee Meeting – May 16, 2016 Page 3 of 8 Chairman Moreno moved to approve the Resolution and recommend its approval to the City Council. Alderman Newman seconded the motion. The motion passed unanimously. V. PONDS SUBDIVISION POND REPAIR PROPOSAL Superintendent Ells explained that there are retention basins with hydraulic drainage systems in the Ponds Subdivision, which was built in the mid-1980s. These hydraulic drainage systems have a very unique design. After 30 years, the functionality of the hydraulic drainage systems became impaired due to the erosion around or near the structures. The Ponds Subdivision Homeowners’ Association requested assistance from the City with financing the repairs or replacement of the hydraulic drainage systems in 2009. The City responded with an offer to assist with financing, under the condition that the Homeowners’ Association maintained the systems in perpetuity. The Homeowners’ Association did not accept the City’s offer at that time. Recently, the Homeowners’ Association approached the City indicating interest in the offer made in 2009. Mr. Ells continued explaining that cost estimates for a permanent solution for the systems were obtained by the City from several sources. The average cost estimate totaled approximately $70,000. Staff is proposing that the City agree to share this cost under the condition that the Homeowners’ Association commits to an agreement claiming ownership and maintenance of the retention basins. The Homeowners’ Association President will be meeting with homeowners in several weeks to discuss this proposal. City Manager Kiely confirmed that this proposal will be a permanent solution for the City, as the Homeowners’ Association will be accepting full ownership and all maintenance of the retention basins. Mr. Ells commented that maintenance of water retention basins in subdivisions installed in the 1990s or after are not the responsibility of the City. Alderman Moreno noted that there are retention basins in her subdivision and asked if language could be added to the proposed agreement reiterating that the maintenance of retention basins installed in the 1990s or after are not the responsibility of the City. Mr. Ells responded that it may be difficult to make a generalizing reiteration like that. Director Thomas explained that a proposal for the design of a replacement hydraulic drainage system was received by the City from Gewalt Hamilton Associates, Inc. The proposal is being presented to the Public Works Committee for their review and recommended approval to City Council. Mr. Ells noted that it would be necessary to obtain a wetlands permit from the U.S. Army Corps of Engineers. City Manager Kiely explained that it would also be necessary for various legal documents to be drafted outlining the specific responsibilities of the City and the Homeowners’ Association. Alderman Moreno asked if the proposed hydraulic drainage system would have a standard design under this proposal, rather than the very unique design of the current system. Mr. Ells confirmed that a standard design is being recommended under this proposal. Alderman Moreno then asked if the continuing Public Works Committee Meeting – May 16, 2016 Page 4 of 8 maintenance of the system would be subsequently easier and less costly. Mr. Ells confirmed that continuing maintenance would be subsequently easier and less costly. He also noted that the City would provide the Homeowners’ Association with a sample maintenance plan. Alderman Moreno noted that the sample maintenance plan could result in maintenance best practices guidelines. Chairman Newman moved to approve the proposal and recommend its approval to the City Council. Alderman Moreno seconded the motion. The motion passed unanimously. VI. UPDATE ON THE DESIGN OF THE WEST FORK / HACKBERRY / WILSON STORM SEWER PROJECT Mr. Ells explained that Baxter & Woodman has been completing the design of the West Fork / Hackberry / Wilson Storm Sewer Project. Specifically, Baxter & Woodman has been testing the hydraulic models developed for the Storm Sewer Project. Moreover, additional survey data was recently obtained by Baxter & Woodman. From the survey data, it has been determined that the estimated costs and scope of the Storm Sewer Project are directly in-line with initial projections. Chairman Waldeck asked if the Storm Sewer Project is on schedule. Mr. Ells confirmed that the Storm Sewer Project is on schedule. He also explained that homeowners present at the most recent Fourth Ward meeting asked if the Storm Sewer Project would impact Ranch Road. The City therefore contacted Baxter & Woodman regarding this inquiry. Baxter & Woodman confirmed that the Storm Sewer Project would reduce street flooding on Ranch Road but by no means eliminate overland drainage paths. Mr. Ells then highlighted several typography features of the area. Specifically, he referenced a low area around a fire hydrant at the end of Ranch Road’s cul-de- sac. He explained that an inlet could be constructed to mitigate ponding occurring in the right-of-way. Mr. Ells also explained that there are depression areas on some privately owned properties. Director Thomas stated that through directional boring, a pipe would be installed to collect this water and move it via an existing storm pipe into the storm sewer on Wilson. Chairman Waldeck asked if the purpose of the pipe would be to mitigate flooding. Mr. Ells confirmed that the installation of the pipe would be to reduce the ponding at the end of Ranch Road. City Manager Kiely suggested that a letter be drafted to the homeowners of the West Fork / Hackberry / Wilson area specifically setting accurate expectations regarding the impact of the Storm Sewer Project on flooding and the remaining potential for flooding on private property. Mr. Ells responded that staff would certainly draft the suggested letter. He also explained that a meeting with homeowners will be scheduled when the Storm Sewer Project design is completed. Alderman Moreno stated that she fully supported the suggested letter and the meeting with homeowners. City Manager Kiely noted that it is critical for homeowners to understand that yard flooding and overland drainage will not be entirely resolved when the Storm Sewer Project is completed. Public Works Committee Meeting – May 16, 2016 Page 5 of 8 VII. UPDATE ON WINWOOD SANITARY SEWER PROJECT Director Thomas stated that Gewalt Hamilton Associates, Inc. is proceeding with the design of the Winwood Sanitary Sewer Project. On June 20, 2016, cost estimates will be presented to the Public Works Committee as well as estimates of the specific number of households that will be affected by the Sanitary Sewer Project. Director Thomas and Mr. Ells recently learned that the Sanitary Sewer Project may be more complex than initially anticipated, as there are multiple sanitary and storm sewer cross-connections installed. Director Thomas explained that the septic tanks of several properties have overflow pipes, which are connected directly to the City’s storm sewer on Winwood. Historically, cross- connections were conventional installations. However, rules and ordinances have changed and cross-connections into storm sewers are no longer acceptable. Chairman Waldeck asked if there is a potential for sanitary waste to enter storm sewers through cross-connections. Director Thomas responded that the potential for sanitary waste to enter storm sewers does exist. He also explained that City Manager Kiely requested that staff sample the storm sewer water. The samples taken had positive fecal chloroform results. Though it is common for storm sewer water to contain fecal chloroform, it is still necessary for the cross-connections to be disconnected. He noted that this will be rather costly, especially with the other improvements being made through the Sanitary Sewer Project. Director Thomas explained that video camera line inspections of the storm sewers were recently completed. He also noted that a certain portion of the storm sewer has been lined. Staff will identify other areas in the City where cross- connections are present. These results will be shared with the Public Works Committee. Chairman Waldeck explained that the City should have a formal policy in place regarding this. Director Thomas and Mr. Martin responded that the City does have a formal policy in place regarding cross-connections. Mr. Martin continued explaining that staff will assemble a database of ‘Tier 1’ and ‘Tier 2’ areas. ‘Tier 1’ areas would be defined as meeting the cross-connection criteria. ‘Tier 2’ areas would be defined as being affected by cross-connections. City Manager Kiely stated that the Winwood Sanitary Sewer Project may be more complex than the Regency Sanitary Sewer Project, as many more homeowners will be affected. It will be necessary that innovative financing mechanisms are considered due to the need for the cross-connections to be disconnected. Alderman Tack stated that it will be critical to clearly communicate the impact of the cross-connections on storm sewer water to the property owners on Winwood. Director Thomas stated that staff has received some feedback. While some homeowners are in support of the Sanitary Sewer Project, others are not. Alderman Moreno asked if there intensities of fecal chloroform concentration levels. Mr. Martin responded that there is a range of fecal chloroform concentration levels. Staff summarized the update by noting Public Works Committee Meeting – May 16, 2016 Page 6 of 8 that a project cost estimate would be presented to the Committee meeting in June, 2016. VIII. OTHER ITEMS  Proposed Estate Lane Planned Preservation Subdivision and Potential Private Storm Sewer Discussion Director Czerniak explained that the Plan Commission would be recommending that City Council support the tentative and final plat and the associated Special Use Permit for the Estate Lane Planned Preservation Subdivision at the City Council meeting on May 16, 2016 (this evening). The Plan Commission heard an initial proposal regarding this matter in June, 2015. Neighboring homeowners responded to the proposal by raising concerns related to increased drainage as a result of the subdivision development. City staff then responded by making minor revisions to the final lot configurations and recommending enhancements to the proposed drainage improvements over and above the applicable requirements. Director Czerniak stated that after extensive review of the concerns raised by the neighboring property owners, it was determined that increased drainage would not result from the subdivision development. Rather, the proposed draining improvements may benefit neighboring homeowners by facilitating drainage. Director Czerniak suggested that staff educate homeowners on the importance of private storm sewer maintenance. She also suggested that staff research the option of cleaning and lining private storm sewers in exchange for City easement ownership. Director Czerniak then requested that the Public Works Committee address the drainage concerns of the homeowners neighboring the proposed Estate Lane Planned Preservation Subdivision. She stated that their concerns were especially pertinent to the Public Works Committee, as the Stormwater Management Policy was recently approved by the Public Works Committee on March 7, 2016. Chairman Waldeck responded stating that the Public Works Committee would accept this request from Director Czerniak. She also stated that there are private storm sewers that could be better maintained. Alderman Moreno stated that it is critical for the typography of the area to be understood. Director Czerniak responded stating that staff would provide the Public Works Committee with typographic information. Alderman Newman stated that investing time in comprehensively understanding the drainage issues being experienced by the homeowners neighboring the proposed Estate Lane Planned Preservation Subdivision is advisable. Alderman Moreno asked if the drainage resulting from the subdivision development could be transferred to a retention basin on Oak Knoll Drive. Mr. Ells responded stating that Bleck Engineering, the contracted engineer of the developer Marlin Ventures LLC, modeled the drainage patterns resulting from the subdivision development. According to the Public Works Committee Meeting – May 16, 2016 Page 7 of 8 models developed, the retention basin on Oak Knoll Drive would not have the capacity to hold the additional drainage. Chairman Waldeck asked Alderman Newman, Alderman Moreno, and Alderman Tack if the request should be accepted. Alderman Moreno stated that the Public Works Committee has a duty to accept the request. Chairman Waldeck agreed with Alderman Moreno. Alderman Tack then asked if the Conway Farms subdivision was experiencing drainage challenges related to their private storm sewers. City Manager Kiely responded explaining that there are private storm sewers throughout the City. He noted that the request for City Council support of the proposed Estate Lane Planned Preservation Subdivision was being confounded by strong sentiments related to stormwater management. Chairman Waldek requested that an informative letter and meeting invitation be sent by staff to the homeowners neighboring the proposed Estate Lane Planned Preservation Subdivision regarding drainage concerns. Alderman Newman asked if legal counsel should be sought. City Manager Kiely responded that the City should continue to provide homeowners with data when drainage concerns are raised. He also stated that expectations related to drainage concerns should be clearly articulated to homeowners. Director Czerniak stated that the Plan Commission has suggested that homeowners review the plans for the proposed Estate Lane Planned Preservation Subdivision and have independent studies completed. Alderman Newman stated that he appreciated the information that was provided to the Public Works Committee. Chairman Waldeck confirmed that the Public Works Committee would accept the request from Director Czerniak.  Distribution of Updated FY ’17 Public Works Committee Meeting Dates The Public Works Committee reviewed the meeting dates. Chairman Waldeck asked if the dates and times worked for the schedules of the other Alderman. Alderman Newman, Alderman Moreno, and Alderman Tack confirmed that the dates and times work for their respective schedules. Chairman Waldek suggested changing a specific meeting date if schedules were particularly heavy at that particular time.  Alderman Tack asked for the number of decaying trees on the Route 60 median strip. City Manager Kiely responded that staff would obtain this data for the Public Works Committee meeting scheduled for June 20, 2016. IX. OPPORTUNITY FOR PUBLIC COMMENT X.

The Public Works Committee is interested in providing you with factual information about drainage in your area and about your obligation as a property owner with respect to the draiutile on your property. The Committee is also interested in considering whether fhere are opportunities the City cm offer to support maintenance and efficient operation of the draintile going forward. Key Points: > Illinois Drainage Law requires all properties to accqrt storm water from upstream properties. Runofffrom upstream properties has historically crossed your property to reach the City storm sewer located on the west side of south Estate Lane. These historic drainage patterns continue today. A storm sewer pipe, also called a drain tile, crosses your property. This drain tile is many years old and like drain tiles found on other properties in this area, was likely installed as part of the Lasker Estate. Rodding and lining the draintile will improve its functionality. The draintile is currently your responsibility, it is on private property and it is not within a public easement. The downspouts and sump pmnp of your home may be connected to the draintile that crosses your property. An overland channel also crosses your property accepting the water from upstream properties that does not get into the draintile and directing it to stormsewers downstream. The Estate Lane Subdivision is designed to avoid any increase in the amount of stormwater that currently flows in a southwesterly direction across your property. As a result of (he improvements that are being required as part of the subdivision, at times, the volume ofstormwater flowing across your property will likely be reduced. The members of the Public Works Committee invite you to join them for a brief, informal discussion on Monday, June 20 , at 5 p.m. The meeting will be at City Hall, 220 E.

LAKE FOSEST, ILLINOIS 60045 . TH. 847.234.2600 . WWW.CrTYOFLAKBFOREST.COM WATER SERVICE DISCUSSION June 20, 2016 Dear Lake Forest Homeowner: The City of Lake Forest closely monitors the water supplied to its residents from the Lake Forest water plant and assures residents that Lake Forest water continually meets all IEPA water quality guidelines and is safe and reliable. You should be aware that lead does not come from the City’s Water Treatment Plant or water mains. However, lead can come from lead service lines running between the water main in the street and house, as well as from plumbing inside the home. Lead service lines are typically only present in older homes built prior to 1950. In accordance with IEPA Lead & Copper Rules, Lake Forest retains an independent, state- certified laboratory to conduct water quality tests on a random sampling of homes with lead service lines. According to IEPA guidelines, the City has never found a cause for concern in any of the Lake Forest homes that have been tested. The City’s records indicate that your home has been identified as having a lead water service line. These records could be out of date, as they might not reflect repairs or replacements made after your original service line was installed. Over the next 30 days, the City will be verifying lead service lines and updating its current records. We ask that you contact Becky Pocasangre, Administrative Assistant of Public Works by email at pocasanb@cityoflakeforest.com or phone at (847) 810-3543 by (date) to schedule an appointment. The service line verification process will only take a few minutes, as the City’s Water & Sewer staff will need to enter your residence for the inspection. We have attached a Frequently Asked Questions document to provide you with some additional information about lead service lines. Thank you in advance for contacting us to schedule your service line verification. Dan Martin Superintendent of Public Works The City of Lake Forest Lead Service Lines Frequently Asked Questions Why is the City inspecting homes with lead service lines? The City’s records indicate that approximately 300 homes in Lake Forest have lead service lines. The City wants to be sure its records are current and keep its residents informed about their service lines. What does the City do to ensure its water is safe? The City’s Water Plant is continually monitored and meets all IEPA water safety rules and guidelines. Additionally, Lake Forest, in accordance to the IEPA Lead and Copper Rule, conducts water quality tests periodically on a sampling of homes that containing lead plumbing. According to IEPA guidelines, the City has never found a cause for concern in any homes that have been tested with lead service lines. Does the City implement any other water safety measures? Yes. In accordance with the 1991 IEPA Lead & Copper Rules, the City has implemented a lead and copper sampling control management program. This program is beneficial to all homes, especially those with lead pipes. This corrosion control method supplies phosphate into the drinking water that provides a preventive coating to pipes, thus reducing the likelihood of lead exposure. Will the City be inspecting my water quality? No. The verification that the City will perform in the next 30 days is designed to confirm lead service lines in Lake Forest. After inspection, staff will be able to inform homeowners if their service lines are constructed with lead. What if I’m concerned about my water quality? If you are concerned about water quality as a result of your lead service line, you may want to have your water tested by a certified laboratory. Water testing is the most effective method to verify if lead is present in water. Suggested laboratories that can test drinking water include:  McHenry Analytical Laboratory: (815) 344-4044  Suburban Labs: (800) 783-5227 or http://suburbanlabs.com/  Illinois Environmental Protection Agency: www.epa.illinois.gov/topics/drinking- water/private-well-users/accredited-labs/index. What should I do if my home has a lead service line? The service line is the responsibility of the homeowner. If you want more information, you can contact a certified plumber to inspect the line and check for lead solders in your home’s internal pipes. Should I replace my service line? A certified plumber can advise homeowners if there is a need for replacement. The surest way to remove all concerns about lead from lead service lines is to remove the entire lead service line. Who pays for replacement of service lines? Service lines are not part of the public water system and are owned and maintained by the property owner. How much does it cost to replace a service line? The actual cost of service line replacement depends on a number of factors including the length of the service line, where the service line is located, and the line replacement itself. A plumbing professional can best determine individual costs. Do I need a permit from The City of Lake Forest to replace my lead service line? Yes. You will need a permit, but the City will waive any permit fees associated with replacing lead service lines. Are there additional measures I can take to ensure my water is safe? The following steps will reduce potential lead exposure:  If you have a lead service line the most effective measure is to have your privately owned line replaced.  Purchase a certified faucet or pitcher water filter that can remove lead from tap water.  Run your water to flush out potential lead. If water has not been used for several hours, run the water for three to five minutes to clear the water that has been sitting in the lines.  Always use cold water for drinking, cooking, and preparing baby formula. Never cook with or drink water from the hot water tap. Hot water can increase the potential for lead leaching from the pipes, solders, and fixtures. Never use water from the hot water tap to make infant formula. Take measures to ensure that children don’t drink bath water.  Do not boil water to remove lead. Boiling water will not reduce lead.  Periodically remove and clean the faucet screen/aerator. While removed, run the water to eliminate debris.  Identify and replace plumbing fixtures containing lead. Brass faucets, fittings, and valves may leach lead into drinking water. Where can I find more information about lead in drinking water? Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at http://www.epa.gov/lead/learn-about-lead.

Consideration of an Ordinance Amending Sections 51.075, 51.077, 39.156, 39.159, 39.160 and 39.164 of the City Code as Recommended by the Finance Committee. (First Reading) Finance Director Elizabeth Holleb and Public Works Director Michael Thomas gave an overview of the recommended changes pertaining to real estate transfer taxes, water shutoff valve (b-box) inspections and water leaks. Ms. Holleb reported that the proposed Ordinance would amend City Code to reflect current practices and allow for a mechanism to ensure location and accessibility of water shutoff valves (b-box) prior to transfer of title to property, and amend provisions to address water leaks on private property. Mr. Thomas reported that current code prohibits all water customers from affecting the operation or function of a water shutoff valve and that in 2014, the City initiated an inventory of all water shutoff valves in the City, and the inventory is scheduled to be completed later this fall. Mr. Thomas also reported that a list of all properties for which the water shutoff valve cannot be located will be compiled and letters would be sent to property owners encouraging them to locate the shutoff valve and to contact City staff to update City records. Ms. Holleb stated that the proposed Ordinance will allow the City to delay the issuance of permits or real estate transfer tax stamps in the event a water shutoff valve cannot be located on a property or is inaccessible. As presented, the property owner would be required to remedy the situation in accordance with long standing Code requirements. Ms. Holleb also noted that on occasion, the City determines that a property owner’s water shutoff valve is nonfunctional. While not part of the inventory or inspection process, the proposed Ordinance would also allow for delay in the issuance of permits or real estate transfer stamps in the event a water shutoff valve requires repair. In these cases, letters will also be sent to notify the property owner. There are approximately 200 or 3% of B-boxes not located yet. The City Council had discussion about water shut-offs, B-boxes and the connecting to real estate transfer tax and would like to table the current Ordinance and asked the staff to bring forward an amendment that included Council recommendations. COUNCIL ACTION: Approve first reading of the proposed Ordinance recommending changes to City Code relating to real estate transfer taxes, water shutoff valve (b-box) inspections and water leaks. Alderman Adelman made a motion to table the item, seconded by Alderman Newman. Motion carried unanimously by voice vote.

(A) Each premises requiring sanitary sewer service shall have a separate and independent connection to a public sanitary sewer where a public sanitary sewer is available or accessible. If a sanitary sewer is not available in the public street or alley abutting a property requiring sewer service, or there is no public sanitary sewer accessible within 500 feet from any of the property lines, a private sanitary sewer and sewage treatment system may be constructed and maintained within the property limits at the expense of the owner. Plans and specifications for private sanitary sewers and sewage treatment systems shall be submitted to and approved by the City Council or its duly authorized designee before construction is started. The owner of any property requiring sanitary sewer services, and dependent upon the use of private sewers and treatment systems shall within six months, after the completion of a public sanitary sewer in a public street, way or easement upon which such property abuts, connect the sanitary sewer from such property into the public sanitary sewer in the manner provided by ordinance and thereupon discontinue the use of any private sewage treatment system. (B) In areas where new sanitary sewers are installed and existing dwellings are served by private sewage treatment systems, the existing buildings, upon request of the property owners, may be permitted to continue using a private sewage disposal system with the approval of the City Council subject to the following conditions: (1) The existing private sewage treatment system has been tested and certified by the City Health Officer, or his or her Deputy, to be in satisfactory working condition; (2) The residence to be served would require a sanitary sewer service of more than 500 lineal feet; and (3) The execution of a covenant by the owner, to be recorded with the County Recorder of Deeds, agreeing to connect the building to the sanitary sewer at the time of any subdivision of the owned premises, or at any time that it is determined that a private sewage treatment system can no longer function in a manner satisfactory to the City Health Officer.

(WJE) performed a limited inspection of the Ferry Hall Bridge located on Mayflower Road between Spring Lane and Rosemary Road. This inspection focused on the south approach span, which exhibits extensive deterioration on the underside of the concrete deck slab. Reportedly, Bleck Engineering Company, Inc. (Bleck Engineering) was performing a routine bridge inspection in accordance with National Bridge Inspection Standards (NBIS) when the deterioration was initially discovered. This report summarizes the condition of the south approach span structure and presents options for addressing the deterioration. Description of Structure The Ferry Hall Bridge (Structure No. 049-6853) is a two lane bridge that crosses a deep ravine tributary to Lake Michigan. It is our understanding that the bridge was originally constructed in the 1930’s and was reconstructed in 1970. The primary bridge structure currently consists of three-span continuous steel girders supported on concrete piers and abutments. A plan view of the existing structure is shown in Figure 1. The roadway was re-aligned when the bridge was reconstructed in 1970, which required the construction of a concrete viaduct to the south of the primary bridge structure. This viaduct that makes up the south approach span is constructed using an 8-1/2 inch thick concrete slab supported on beams and columns along the east edge and the original retaining wall along the west edge. A transverse cross -section through this viaduct structure is shown in Figure 2. Available drawings indicate the bridge was designed for H15-44 loading. Work performed in the mid-1990’s involved the replacement of the deck and barrier rail on the primary bridge structure; however, the south approach span deck was rehabilitated rather than replaced. Rehabilitation involved scarification of the top 3 to 4 inches of the original 1970’s concrete slab and replacement of concrete and the top mat of reinforcing steel. As a result, the current south approach span slab consists of two layers. The bottom several inches of the original 1970’s slab and associated reinforcing steel comprises the lower layer, and the newer, mid-1990’s concrete and reinforcing steel comprises the upper layer. The thickness of the existing south approach span slab was measured at several locations with values ranging between 9 inches and 11-1/2 inches. An overall view of the south span viaduct is shown in Figure 3. Mr. Robert Ells The City of Lake Forest June 15, 2016 Page 2 Field Investigation and Observations WJE initially visited the site on May 19, 2016 to meet with representatives from The City and Bleck Engineering. During that visit, an area of approximately 150 square feet on the underside of the south approach span slab was visibly delaminated from the deck above and presented an overhead falling hazard. This deteriorated area is shown in Figure 4. Follow-up site visits were made by WJE on June 1st and 9th, 2016 to observe this area after crews from The City knocked down the delaminated concrete. This area after the concrete removal is shown in Figure 5. During these site visits, WJE sounded the topside and underside of the concrete deck within the south approach span. In addition, reinforcing bar section loss measurements were performed at selected locations within the area shown in Figure 5. Finally, samples of the deteriorated concrete on the underside of the slab were removed for laboratory testing, and four cores were removed to evaluate the condition of the slab above the lower mat of reinforcing steel. Visual observations on the top of south approach span deck revealed transverse shrinkage cracking spaced at approximately 2 to 3 feet, as shown in Figure 6. Map cracking was also noted in the segment of supported deck adjacent to the retaining wall support along the west edge. The crack pattern on the underside of the deck appeared similar to the pattern observed on the top side. In addition, many of the cracks on the underside of the deck exhibited moisture staining and efflorescence, as shown in Figure 7. A chain-drag survey on the top of the south approach slab structural deck identified two roughly 3 ft x 15 ft areas of delaminated concrete and other smaller areas of delamination. Acoustic sounding was performed on the soffit of the south approach slab, and this survey indicated that the majority of the underside of the deck was delaminated. In the area where the loose concrete had been removed, severe corrosion and section loss was noted on the reinforcing steel bars, and the section loss was typically measured to be between 20 percent and 50 percent of the original bar area. In addition, the concrete directly above and below the bars had a fractured appearance, likely caused by the corrosion of the transverse reinforcing bars at the bottom of the slab. As a result, there was very little effective bond between the reinforcement exposed in the concrete removal area and the generally sound concrete above, as shown in Figure 8. The lower portions of the concrete beam along the east edge of the south approach span slab was visually inspected, and this effort indicated the beam contained concrete delaminations over approximately 50 percent of its length, and an example of which is shown in Figure 9. In general, the columns appeared to be relatively good condition and only small localized areas of concrete delaminations were noted. Four concrete cores were removed from the south approach span slab, and these cores are shown in Figure 10. The core samples revealed that the concrete above the longitudinal bars of the bottom mat of reinforcing steel is generally sound, except for the shrinkage cracks and isolated delaminations discussed above. The cores also reveal the bond line between the original 1970’s slab and the newer mid-1990’s slab, as shown in Figure 11. Inspection inside the core hole confirmed that the concrete directly adjacent to the transverse bars in the bottom mat of reinforcing steel is severely deteriorated, as shown in Figure 12, which is a core from an area outside of the large concrete spall shown in Figure 5. Mr. Robert Ells The City of Lake Forest June 15, 2016 Page 3 Laboratory Testing Concrete samples were obtained from the delaminated concrete between the bottom reinforcing bars in order to approximate the chloride levels in the concrete near the lower reinforcing bars. Acid-soluble chloride analyses were performed on two samples essentially according to ASTM C1152, Method for Acid- Soluble Chloride in Mortar and Concrete. Studies have shown that chloride contents above 0.02 to 0.03 percent by mass of concrete (depending on the cement content) can promote corrosion of embedded steel in normal weight concrete. The chloride contents of both samples were well above this threshold and would be expected to greatly promote the corrosion of embedded steel in the presence of sufficient moisture and oxygen. The results of the two chloride testes can be found in Table 1. Table 1. Chloride Contents Sample Acid-Soluble Chloride, % by mass of sample 1 0.294 2 0.274 Findings and Discussion The field observations, including coring, revealed severe deterioration of the original (1970’s vintage) concrete and reinforcing steel of the south approach span. This deterioration included widespread delaminations on the deck soffit, section loss of the primary reinforcing steel on the order of 20 to 50 percent of the original reinforcing bar area, debonded reinforcing bars, and through thickness cracking with moisture staining and efflorescence. Delaminations on the concrete edge beams was also observed. These findings are consistent with a superstructure rating of “3 - SERIOUS” for NBIS Item 59, as identified in the Illinois Highway Information System - Structure Information and Procedure Manual published by the Illinois Department of Transportation (IDOT). The deterioration is primarily related to corrosion of the original reinforcing steel, a process that was substantially accelerated by the presence of chlorides, most likely from de-icing salts. The widespread delaminations were caused by the accumulation of corrosion products, which take up much more space than the parent materials. The concentration of expansive forces at the plane of the lower reinforcing steel mat caused the concrete below to break free from the concrete above. The resulting voids comprised locations where moisture could accumulate and further accelerate the corrosion process and possibly initiate freeze/thaw damage within the adjacent concrete. The observed deterioration has reduced the load-carrying capacity of the concrete slab for the south approach span. Calculations performed by WJE indicate that this slab can no longer reliably support the H15-44 vehicle load for which it was designed. As a result, The City should take precautions to limit the weight of the vehicles that utilize the south approach span structure , such as posting a load limit or restricting traffic to the west lane. Load posting the bridge structure for a live load limit of 5 tons would allow passenger vehicles, pick-up trucks, and possibly some landscaping vehicles and ambulances; however, heavier vehicles would be excluded. Alternately, because the supported slab only takes up a portion of the approach structure width, traffic on the south approach structure could be restricted to the west lane. This would require installation of temporary traffic barriers and traffic control measures, such as stoplights, at each end of the restricted areas. Restricting traffic to only the west lane would not require a posted live load limit, which means it would be able to carry the original H15-44 design load (15 tons). Given that the deterioration will continue to progress, we believe that the structure should be re-inspected Mr. Robert Ells The City of Lake Forest June 15, 2016 Page 4 in one year to re-evaluate the appropriateness of the selected safety precaution (load posting or lane reduction). The condition of the south approach span slab structure is such that extensive repairs or replacement is required to restore the load-carrying capacity. In order to determine the feasibility of each option, additional evaluation similar to the work typically performed for IDOT Bridge Condition Reports (BCRs) will likely be required to compare the pros and cons of structure repair/rehabilitation and structure replacement. In addition, this work should include an evaluation of the 1930’s vintage retaining wall to determine if it is adequate for continued use. Finally, calculations for the remaining structure should be reviewed to determine the capacity of the primary three-span girder structure, as the south approach span structure may not need to be repaired/replaced to current design standards if the adjacent structure has a lower design loading. For the purposes of discussion, an order-of-magnitude cost for structure replacement is approximately $400,000 to $600,000. If it is found that repair is a feasible option, the order-of-magnitude costs would be approximately $150,000 to $300,000; however, the repairs would likely consist of shotcrete repairs or form- and-pour repairs and would generally be less durable than the deck replacement option. Currently, the remaining service life of the existing retaining wall is not known, and this would significantly add to the cost if the scope includes anything more than localized concrete repairs or soil anchor stabilization. We appreciate the opportunity to be of assistance in this matter. Please do not hesitate to contact us with any questions. Sincerely, WISS, JANNEY, ELSTNER ASSOCIATES, INC. Andrew R.
