Barber Richard J. Figurelli, Supt./Water & Sewers David Stoneback, Asst. Supt./Water & Sewers Regina Steuben, Asst. Supt./Water & Sewers Greg Ramon, Distribution & Sewer Chief Others Presents John Velon, Harza Environmental Services (HES) Richard Persaud, (HES) Dan Gallagher, (HES) The Flood & Pollution Control Commission met on January 20, 1993 in Room 2404 at the Civic Center. The Chair called the meeting to order at 8:02 P.M.. M I NUTS The minutes of the September 23, 1993 meeting were unanimously approved. PHASE 1 -- PROGRESS REPORT David Barber, Director of Public Works, introduced Dan Gallagher from HES to review the status of Phase 1 Long Range Sewer construction activities. Mr. Gallagher stated that activities in drainage basin S03 were complete. The final punch list items are currently being taken care of and inspections will be made to finalize the loan agreement with the IEPA for the Phase 1 S03 improvements. Phase 1 construction activities in basins S06 and S13 are approximately 80% complete with the open Gut sewer activities in these basins 95% done. The tunnel on Payne and McDaniel has been excavated and lined. Primary work remaining involves the completion of the connecting structures to the channel. I I FPCC MINUTES January 20, 1993 Page 2 EHASE II - PROGRESS REPORT Mr. Gallagher summarized the work that had taken place in the three areas included in Phase II of the Long Range Sewer Improvement Program. Area 1 involves construction activities primarily in the north central section of the city; area 2 includes the section of tunnel on Main Street from the Channel to Dodge and some smaller open cut sewers in the area; and area 3 construction activities are located in Basin S13 and when complete will finish the sewer improvements in that Basin. Area i is currently about 5% complete at this time with work mainly limited to three outfalls and the structure off Emerson. Area 3, located in Basin S13 is 60 to 70% complete. Most of the open cut sewer has been installed. Area 2 is the largest portion of the contract and involves the large diameter tunnel on Main Street. Currently the contract is 5`!. complete. Excavation is underway for the connecting structure to the Channel located off Main Street. Mork has also begun at the intersection of Main and Dodge in preparation for the tunnel running north and south on Dodge. Jacking the pipe on Dodge will begin in a couple weeks. Construction on the large diameter tunnel on Main Street is expected to begin next week. Construction in Area 2 will involve the closure of Main Street between Dodge Avenue and McCormick. Dodge Avenue will remain open throughout the period. Meetings are being held with neighbors to provide information and minimize the impact of the construction activities. PHASE III - PROGRESS REPORT David barber summarized the two areas of activity included in Phase III. The first is the rehabilitation of the existing combined sewer on Main Street. Meetings have been held bi-weekly with the Main Street Merchants so that the project is set up and scheduled with their involvement. Council has authorized an advertising consultant to assist in marketing the Main Street business area to minimize the negative impact construction activities will have on the businesses. The plans are nearly completed for the remaining work involved in Phase --^`- III. We have submitted the documents for review by the Metropolitan Water Reclamation District (MWRD) and the Illinois Environmental Protection Agency (IEPA). The project involves tunnel construction on Main Street from Dodge Avenue to Judson and south on Sherman from Main Street to==3r ❑ak tan . �_ y FPCC MINUTES January 20, 1993 Page 3 eBA$a—LJLI - FUNDIM David Barber summarized the total costs involved in Phase III. The project is presented in the budget on the basis of moving forward utilizing general obligation (GO) bonds to fund both Phase III costs and Phase IV design for an estimated total of 23.35 million dollars. The increase in the sewer user charges proposed in the upcoming budget provides funds for the repayment of Phase 1 and 2 debt service which has already been established. It also assumes the need for one interest payment on the proposed 23.35 million dollar bond issue. Mr. Barber discussed the projections for sewer user charges for the upcoming ten years. He clarified that the spreadsheets assumed GO bond funding for phase II and III only. All other phases assume IEPA loan funding. He noted that we are applying for funding for Phase III improvements through the IEPA loan fund. However, at this time it does not appear likely funds will be available and therefore the projections assume the GO bond funding. The commission discussed the possibility of postponing the second half of Phase III. This would result in obtaining bond funding for approximately 2.5 million at this time to fund the rehabilitation of the Main Street combined sewer and delaying the tunnel work and associated relief sewers until later in the year. It was clarified that we are continually applying for each phase through the IEPA. Phase IV design funds are included in the 93-94 budget to enable us to be prepared for IEPA funding when available. Mr. Lauterbach made a Motion directing staff to analyze the impact of splitting Phase III into two sections and going out for bond funds on the $2.5 million rehabilitation of Main Street first and delaying the remainder of the project for six months. The most favorable scenario should be submitted to City Council. The motion was unanimously approved. PHASE IV -PE 9kGN Mr. Barber explained that at this point in time we do not have a proposal for Phase IV design but wanted to initiate discussion and explain the areas that are included in that phase. He explained that we would like to request HARZA to submit a proposal for design services for Phase IV and include in that proposal marketing and advertising for businesses. He emphasized that at all times we need to have the design work prepared for the next phase of construction so that in the event dollars from the IEPA become available we are prepared. Alderman Lanyon made a motion to request a proposal from HES for design services for Phase IV of the Lang Range Sewer Improvements. Ned Lauterbach seconded the motion. The motion was unanimously approved. W IYiIIW »r Yi . ai it I u I u I I I it i 1 ill �� W II III V� I V�I �d it FPCC MINUTES January 20, 1993 Page 4 RESOLUTION RESTRUCTURING COMMISSION Alderman Warshaw summarized the resolution and memorandum outlining the proposed changes to the FPCC commission resulting from the reduction in City Council size from 18 aldermen to 9. The resolution decreases the number of aldermen on the commission from four to two and adds two citizen members in their place. The result is a commission comprised of two aldermen and four citizen members. At this time the City Manager is asking that the commission review the resolution and submit any comments to David Barber prior to its introduction in Council. Ned Lauterbach commented that he has trouble with the Jth paragraph beginning with "Whereas" in the resolution. The fifth paragraph of the resolution states that the consolidation of council will result in a more efficient and effective conduct of City business and affairs. He felt personally that the result may very well not be more efficient government and that in any case that paragraph is unnecessary. He also commented that the last paragraph beginning with "Whereas" of the proposed resolution would be better worded as followss "WHEREAS, a change in the composition and reporting procedure of the Flood and Pollution Control Commission will result in an administration which would be as efficient and comprehensive as possible." It was also noted that the resolution specifies reduction of the aldermanic positions on the commission from four to two but does not specify the increase of citizen membership from two to four. It was determined that the citizen members should have expertise in the fields of engineering, construction, or finance. Ned Lauterbach made a motion to submit the changes outlined in the above paragraph. Alderman Lanyon seconded the motion. The motion was unanimously approved. There being no further business, the meeting was adjourned. Respectfully submitted, Richard J. Fi urelli I "DRAFT, NOT APPROVED" MINUTES OF FLOOD AND POLLUTION CONTROL COMMISSION MARCH 17, 1993 Members Presents Alderman Roberta Warshaw, Chairman Alderman Edmund Moran Alderman Beth Davis Ned Lauterbach Dr. Michael Goodkind Members Absents Alderman Richard Lanyon Staff Presents David H. Barber Richard J. Figurelli, Supt./Water & Sewers David Stoneback, Asst. Supt./Water & Sewers Regina Steuben, Asst. Supt./Water & Sewers Others Presents John Velon, Harza Environmental Services (HES) Richard Persaud, (HES) Dan Gallagher, (HES) The Flood & Pollution Control Commission met an March 17, 1993 in Room 2404 at the Civic Center. The Chair called the meeting to order at 7s55 P.M.. MINM5 The minutes of the January 20, 1993 meeting were unanimously approved. PHASE,1 — PROGRESS REPORT David Barber, Director of Public Works, introduced Dan Gallagher from HES to review the status of the Long Range Sewer construction activities. Mr. Gallagher was asked to highlight any specific problems occurring in any of the phases currently under construction. He stated that Phase 1 activities have been going very smoothly with the intersection of Payne and Central Park anticipated to open next week. Phase 1 construction activities in basins 506 and S13 are appro;;imately 6U'/. complete with the open cut sewer activities in these basins 95% done. The tunnel can Payne and McDaniel has been excavated and lined. Primary work remaining involves the completion of the connecting structures to the channel. FPCC MINUTES March 17, 1993 Page 2 PHASE � — PRQMSS REPQRJ Mr. Gallagher indicated that there have been some problems with the Phase II tunneling north on Dodge Avenue from Main Street. There have been water main breaks which resulted in the hole being flooded and the need to dry out equipment. This has resulted in the contractor being slightly behind schedule. It is believed that the water main breaks occurred as a direct result of the tunneling under the water main on Main. The tunnel initially had some up and down movement which results in ground heaving and stress on the water main above. The contractor is underway now and should be at Lee street in approximately two weeks. The critical structure in terms of scheduling is the structure at Dodge and Main. This must be completed by October so that the structure can be closed and paved in the fall prior to the closing of the asphalt plants. This has been emphasized to the contractor. The contractor is slightly behind schedule with the 60 inch pipe and still waiting on the boring machine for the 120 inch section. This machine should have been here four to six weeks ago and it is anticipated it may still be three weeks coming. This does present concern regarding the ability to meet the October scheduling criteria for Main and Dodge intersection. PHASE III — PR ORESS REPORT David Barber summarized the two areas of activity included in Phase III. The first is the rehabilitation of the existing combined sewer on Main Street. He commented that working with the Main Street community has been exciting and rewarding. The benefits of obtaining community input and support is evident and the process will be used as a model for future projects. The contract was awarded to the low bidder, Kovilic Construction, in the amount of $2.164 million. Construction is anticipated to begin April 12, 1993. Mr. Barber added that the timing of the bid process had prevented the item being brought before the Commission prior to submittal for Council approval. The Commission discussed the process in which items are approved by Council. It was decided that all items would be brought before the Flood and Pollution Control Commission prior to submission to Council. It was also emphasized that all items regarding the Main Street community meetings and notices would be sent to the members of the FPCC. Alderman Moran asked if the City were to get the IEPA loan, how much it would save us. Mr. Barber stated that the last loan of $20 million dollars was equivalent to a $5 million dollar grant or savings compared to going out for bonding. CMr. Barber stated that the design on the remaining portion of Phase III, the relief sewers, is near completion. The project is anticipated to go out for bid in May. We are hoping for a significant portion of the funding for Phase III from the IEPA Water Pollution Control Revolving Loan Fund. 6 FPCC MINUTES March 17, 1993 Page 3 PHASE III — EBOP25AL FOR ENG. SERVICES DURINS CONSTB_UCTION David Barber presented to the Commission a proposal for engineering services during construction of Phase III relief sewers. The proposal was in an amount not to exceed 1.2 million dollars. The services are paid for at unit prices and are not fixed but paid for as work progresses and is spent. Harza will be allocating 20% to WBE and MBE enterprises on this contract. Alderman Davis moved approval of the proposal from HARZA for engineering services during construction of Phase III. Ned Lauterbach seconded the motion. The motion was approved. E1Hg$IV — P OPOSAL FOR DES I [3N EER V ICES David Barber opened the discussion of the Phase IV area of construction for next year. This is basically a tunnel from the channel on Lake Street to Dodge or to Darrow, which will be looked at as a less disruptive alternate route, then from Church Street south to Crain. It will also include 15,600 feet of new relief sewer. Mr. Barber presented to the Commission a proposal from Harza to provide Engineering Services for design. This proposal included Harza's intention to subcontract up to 20% of the work to local minority and women's business enterprises. Alderman Davis moved approval of the proposal from Harza. Alderman Moran seconded the motion and the motion was approved. = - FUTURE PHAS I NCi Mr. Barber explained that the IEPA loan program is set up to provide �- funding to those projects that are designed and ready for construction by March 31. In view of the prospect of the IEPA having more funding available, Staff feels it would be prudent to develop the next phase at this time. Mr. Barber presented a map outlining the areas that are under construction, phase III and IV which are in the design phase or nearing construction and the remaining phases based on the facility plan. In light of the possibility of additional monies available from the IEPA, Staff has looked at what areas may be best to go forward with given what is under construction and design and how some of these remaining phases might be lumped together to match available funding. Three different options were selected. A diagram of the three options was presented. Each of the options involve roughly 12 million dollars of construction activity. The first option l includes work in the far northwest section of the city and a section of ` work on Maple avenue from Main Street to Davis St. Option II includes installation of a tunnel on Simpson St. from the Channel to Maple Ave and some additional open cut relief sewer surrounding this tunneling. Option III involves completing the tunnel McDaniel Avenue and open cut work cast and west on Lincoln, Noyes and Park Place. FPCC MINUTES March 17, 1793 Page 4 Mr. Barber commented that Option 1 may not be the best option at this time due to all the construction that has been in that area for the last year and a half. Particularly the dropshaft at Central Park and Payne Street. Option 111, presents some of the same problems, however McDaniel Avenue has always remained open and the construction impact in that are has not been as disruptive. In summary, either option III or Option II may be the most logical choices at this time. The commission discussed the above options and it was decided that Option three, which extends the tunnel on McDaniel Street and the east west open cut relief sewers on Lincoln, Park Place, and Noyes would be the best at this time. David Barber stated he would solicit a proposal for design services from Harza for this section. FUTURE Al CTION OF THE FCC Mr. Barber informed the Commission that City Council had incorporated the FPCC comments regarding the commission structure into a resolution. The future commission will consist of two aldermen and four citizen members. The new Council rules with respect to committee chairs indicate that committees consisting of aldermen and citizen members which report to standing committees must have a citizen member as the chairman. The new resolution regarding the FPCC stipulates that the FPCC will report to the Administration and Public Works Committee. Therefore, the new chairman must be a citizen member. The new Council will be officially placed into office on May 10, 1993. At that time, the Mayor will appoint the aldermanic representatives for the Commission. Two additional citizen members need to be appointed. The meeting in May will be dependent on the Commission's structure and the ability to get together a quorum at that time. It was suggested that if you know of citizens who are interested and qualified to serve on the FPCC, it may be helpful to encourage their submittal of an application to the mayor. In addition, the new Council rules also specify that length of service is limited to two three year terms. There being no further business, the meeting was adJourned at 9142 p.m..

Supt./Water & Sewers Others Presents Jonathan Fiske John Velon, Harza Environmental Services (HES) Richard Persaud. (HES) Dan Gallagher, (HES) Thomas Rowlett. (HES) The Flood & Pollution Control Commission met on June 16, 1993 in Room 3650 at the Civic Center. The Chair called the meeting to order at 7s50 P.M.. Alderman Holzman requested an update on the status of the Illinois Environmental Protection Agency (IEPA) loan application for sewer improvements. David Barber informed commission members that an IEPA loan was obtained for Phase 1 sewer improvements. All of the Phase II improvements are financed from General Obligation Bond funding. Phase III includes Main Street combined sewer improvements currently underway and relief sewer improvements which have been bid and are on the agenda for discussion this evening. An IEPA loan was received in the amount of approximately $1,600,000 for the Main Street improvements. This amount represents about 60% of the total cost. We received word last week that the City will be receiving between 9 and 9 Million Dollars for the remaining portion of the Phase III project which will be dealt with in more detail later in the meeting. The interest rate will be at 3.36%. Therefore, a portion of the anticipated bond notes told earlier this year when we assumed no IEPA funding, will be able to be refunded, reducing that long term debt. !iiMUM The minutes of the March 17, 1993 meeting were unanimously approved. t COMM-SI I gN__ORPAN I Z.TIQN ` David Barber discussed the Commission'& organization. The Commission is to consist of six individuals; two aldermen and four citizen members. We currently need two additional citizen members appointed by the Mayor. An additional citizen member will be required as this will be Dr. Michael Goodkind's last meeting, making a total of three vacancies. Two applications have been received by the mayor to data. FPCC MINUTES June 16, 1993 Page 2 GQMM RMN QRAAU-ZATYAN—I=Iffs_) David Barber explained that the council rulings approved by the old council (of is) provided that commissions that were comprised of aldermen and citizen members, reporting to 'a subcommittee, be chaired by a citizen member. This ruling was changed at the last council meeting and the Commission is now chaired by an alderman appointed by the Mayor. Mayor Morton has appointed Alderman Kent as chairman of this Commission. F4ZURE OR1.5-NTATXPN-- E6S��]N FD_"EW MEMBERS Mr. Barber explained that as soon as the Commission's membership is complete, he would like to conduct an orientation session for new members. This will involve going through the Sewer System Facilities Plan and some of the history of the Commission to update the new members on exactly where we are to date. If Commission members are all on board by the next scheduled meeting in July, then the orientation session will be held at that time. P $E_ I (8Q6/813) — PROORERS__ REF QRT David Barber introduced Pan Gallagher from HES to review the status of the Long Range Sewer construction activities. Mr. Gallagher stated that the area S03 has been complete for about one year. We are currently in the process of walking the area to complete a check to assure all items under the one year warranty are inspected. We have not found any large defects. The cost of this project was approximately 3 million dollars. Phase 1 (S06/SI3) construction activities are approximately 90% complete. McNally Tunneling is the contractor and completion is anticipated in the next three months. Remaining work is located at Emerson and McCormick and at Mulford and the Channel. The contractor is on schedule. This contract is in the area of 13.5 million dollars. PHASE I I_ — PROGRESS.REPORT r e4 1_ and Are-3-)- Mr. Gallagher explained that the Phase II contract is divided into three sections; area 1 in the north, area 2 in the center of the city and Area 3 in the southern section. Area 1 is awarded to the DiPaolo Company and they are approximately 36% complete at this time. Work is expected to be completed in September. DiPaplo is also the contractor in Area 3. Significant progress has been made in this area. This work should also be completed by September of this year. C FPCC MINUTES June 16, 1993 Page 3 This project is located on Main Street between Asbury and Hinman. The cost of the project is approximately 2.5 million dollars and involves the replacement of a hundred year old sewer on Main Street in difficult soil conditions and in a congested area. This week the contractor completed the first phase of this job between Elmwood and Custer to allow for the opening of the Custer Street Fair. Street base course and sewer structures are in place in this section and the remaining work will include the sidewalk pavers along the business district and the surface course on Main Street. The construction on Main Street is on a very tight schedule with completion set for September. The work involved in the closing and detouring of traffic as well as the degree of technicality associated with the age of the sewer, soil conditions and number of utilities makes this job extremely difficult. Currently work has been approved for Sundays and it is anticipated the contractor will continue to work Sundays in order to make the targeted deadlines. The project is approximately 20% complete to date. Mr. Gallagher and Mr. Barber explained the public input involved in this project and the participation with the businesses in the area. Meetings are held regularly with the Main Street Business community to keep them informed and abreast of the project progress. A steering committee comprised of the businesses was involved from the beginning of the project and many of the details of the project such as the use of pavers vs. poured concrete sidewalks were suggested by that committee. The level of involvement has proven to be very successful in making for a project that both the City and the community support. PHASE I J — AREA 2__�1AR I NO CDATRACT Mr. Gallagher provided a brief status of the construction. He described the area using visual aids. The major project components are a connection to the Metropolitan Water Reclamatirin District TARP system at Main and the Channel, tunneling wort, on Main Street and Dodge Avenue, and open cut sewer wort; on Lee. Darrow and Asbury. The open cut construction is in place on Lee and Asbury. The 60" tunnel going north at Main and Dodge is complete. The tunnel construction between the Main Street site and the Main and Dodge intersection is currently suspended due to problems the contractor has had working at the Main Street site. The mechanism for constructing this tunnel is pipe jacking where the pipe is pushed through the ground and at the face of the first pipe is a tunnel boring machine. The contractor has had problems at the shaft where the jacking takes place. One problem relates to excessive jacking forces at the shaft which caused the Jacking restraint to move. Shortly thereafter the contractor experienced a partial failure of the excavation support system at that shaft. The contractor is responsible for designing and excavating the "hole" to execute construction activities within that shaft. Last week a portion of the support system failed and the contractor has been unable to proceed with that activity. Jacking is currently suspended as well as other construction activities at that shaft. Wi I I .. , i I J . W FPCC MINUTES June 16, 1993 Page 4 e 1A I -- AREA 2 — ME KI 4.c�t'l?_ The contract is approximately 13 million dollars and the contractor is about 30% complete. The schedule provides for Completion of the tunnel work and open cut sewer work by August/September of this year. We are very concerned with the contractor's ability to meet that schedule. The deep shaft construction at the Main Street site is going considerably better than the jacking operation. This shaft is roughly 170 feet deep with the last 100 feet excavated in rock. The contractor utilizes blasting techniques to excavate. Mr. Barber displayed a brief video of the shaft construction site. The video displayed the wall the jacking machine pushes against and the concrete ring beams around the perimeter of the structure. The pipe being jacked is 10 feet in diameter. Grout is pumped around the pipe as lubrication. On good days the contractor is able to push 15 to 20 feet of pipe. The hazards of the pipe freezing up if the operation is stopped was discussed. If it sets too much and they cannot get moving another intermediate shaft will be required on Main Street. The video displayed the failure in the shaft previously discussed. They should be in a position to begin jacking again early next week. The impact on the project is the difficulty in meeting the target date in September for completion of the open cut work so that we can open up the Dodge/Main intersection for the winter. It doesn't appear at this time to us that Marino will be able to complete the project according to the =_- contract. He will be asked to supply a means and methods schedule to accomplish what is needed to get back on schedule and meet contract deadlines. PEASE _I I I ___ 101 D RES-MTS David Barber summarized Phase III work explaining that it is divided into two sections. Contract A involves a 36 and 24 inch sewer on Grey and Brown. 48" sewer on Madison and Dewey, 24 and 18" sewers on Dodge, Seward and Keeney, 24, 36 and 30" sewers on Cleveland and Wesley. We received bids from five or six contractors for contract A. The review of that bid document is not yet complete and we anticipate a recommendation from the consultant in the next week. If we decide to move forward on that contract, information will be distributed with a request for approval rather than conducting a special meeting. i. r FPCC MINUTES March 17. 1913 Page 5 PHA III Hj_g R99 LTS I Cow.?_ . Contract B involves the tunnel an Main Street from Dodge Avenue to Judson. It also involves tunnel an Sherman Avenue south from Main Street to Cakton and open cut sewer construction an Sherman, Washington, Monroe, Austin and Mulford. J.F. Shea submitted the low bid for the base and the alternates. Richard Persaud, HES, explained the alternates involved. Staff is recommending the award of Contract B to J.F. Shea including alternate number 2 and 4 for a total contract cost of $13,287,972. Alternate #2 allows for installation of the 48" sewer on Sherman and Austin by tunnelling instead of open cut construction at a cost increase of $134,465. Alternate #4 requires the contractor to construct the 108 inch sewer on Main Street from Robert Crown Center to Dodge Avenue by tunnelling at an additional cost of $507,150. This alternate would keep traffic disruption on Main Street to a minimum. Staff is also recommending award of the sewer lining portion of the contract directly to Insitufarm Midwest in the amount $377,020. Upon approval, both items will be brought to Council at the next meeting. Final award will also be contingent upon award from the IEPA revolving loan fund. Ned Lauterbach moved approval. Dr. Michael Goodkind seconded the motion. The motion was unanimously approved. Alderman Holsman asked if there was any requirement as to a total number of minority participants specified by the contractor for training on this = project. Richard Persaud responded that the documents require the training and employment of 16 people. David Barber clarified that this is a very _= similar program as that used by Marino. The contracts require that the contractor subcontract 25% of the work to minority business, small business, disadvantaged business or Evanston business. Mr. Barber added •P that he will be discussing with the contractor the importance of using Evanston firms whenever possible. IF I FUMUM SCHEDULED BEET DIGS _ _ -_ The next regularly scheduled meeting is July 21, 1993. The remaining scheduled meetings in 1993 are September 22nd and November 17th.

The Chair called the meeting to order at 7:05 P.M.. XIIRMS The minutes of the June 16, 1993 meeting were unanimously approved. PROJECT STATUS REPORTS Phase 1 Dan Gallagher, HES, provided the Commission with status reports on the construction progress in each Phase of the Long Range Sewer Improvement Program (see attached memorandums). Phase 1, Basin S03 is complete. Mr. Gallagher explained that a walk-through inspection had been completed and provided the Commission with a description of the process taken during the walk through inspection. No major defects were revealed and the final payment was made to the contractor for this portion of Phase 1. Mr. Gallagher stated that construction in Basins S06/S13 is currently 95% completed. Final completion is anticipated in September, 1993. The question was asked what the incidence of basement backups was in Basin S03 after the recent heavy rains. Mr. Persaud, HES, informed the commission that there were no complaints and that flow monitors in the area confirmed that the sewer system did not surcharge. Staff is preparing a survey to residents of the area seeking their input. This should insure that if there are any problems in the system we will be informed. FPCC MINUTES July 21, 1993 Page 2 Phase II Dan Gallagher provided the Commission with a brief outline of the areas included in Phase II of the Long Range Sewer Improvement Program. Phase II consists of three areas. Area 1 and 3 are under contract with DiPaolo Construction. Area I in the north area of the City is approximately So% complete to date. Area III, located in the southern section of the City is currently about 80t completed. Construction of sewers in both of these areas is being done utilizing open cut construction techniques. Completion of these sewers is anticipated in September, 1993. Phase II - Area 2 - Marino Con0trUgLion Mr. Gallagher described the location of the Area 2 contract. This work involves the dropshaft construction at Main Street and the North Shore Channel and the construction of the tunnel from the Channel to Main St. and on Dodge Avenue. Currently this contract is approximately 35t completed. (see attached status report). Mr. Gallagher briefly reviewed the delay in the project due to construction problems at the Main Street/North Shore Channel site as explained in the minutes of the June 16, 1993 meeting. The shaft has now been stabilized and is safe for entry. However, there has been little progress due to additional management problems experienced by the contractors since the last meeting. Marino Construction has now entered into a management contract with Jay Dee Contractors. Jay Dee is an experienced contractor in tunneling operations. They will be taking over management responsibilities at both the Main Street/North Shore Channel site and the Main St/Dodge Ave. site. J.D. may alter construction techniques and is currently investigating both sites. They will be submitting a revised schedule upon completion of their inspections. It is anticipated installation of the 120" sewer on Main Street will be completed in December of 1993 which represents a 4 month delay. In response to a question regarding penalties assessed to the contractor for delays, it was clarified that the contract does include a provision for penalties. To date no penalties have been assessed. PHASE III. MAIN ST. COMBINED SEWER REHAB Mr. Gallagher briefly summarized the combined sewer project on Main Street. He explained the project involved the replacement of a 100 year old brick sewer which was beyond repair. The project is currently about 25% complete (see attached status report). New sewer has been installed on Main between Custer and Elmwood and restoration in that area is currently underway. Main Street should be open to Ridge Avenue by September, 1993. The intersection of Chicago Avenue and Main Street should remain open throughout the construction period. One half of the intersection will be closed at a time. FPCC MINUTES July 21, 1993 Page 3 PHASE III - CONTRACT "A" & "S" Tom Rowlett, RES, described the work included in Contract A which primarily involves the installation of relief sewers tributary to the Main Street tunnel. Melon Stewart Construction was the low bidder for this contract and was determined to be a qualified contractor. However, due to the current unavailability of IEPA funds for this work coupled with the delays experienced in the construction of the Main Street tunnel, it has been decided to reject all bids at this time. we anticipate the project will be bid again in late 1993 or early 1994. DESIGN UPDATR Phase IV Using visual aids, Tom Rowlett briefly described the work included in the Phase. It includes the construction of a drop shaft at Lake Street and the North Shore Channel. The Long Range Sewer System Facilities Plan originally included the construction of a tunnel on Dodge Avenue and Lake Street. To avoid the disruption on these major thoroughfares, Staff has analyzed alternatives to reduce the impact of construction on area. Two alternatives were selected, both increase the hydraulic protection to the area and decrease construction interference. The construction alternatives were described in Layout 2 and Layout 3 (see attached). Both plans move the proposed tunnel construction off of Dodge Avenue and Lake street to Darrow and Greenwood. This eliminates the need for shaft locations on the primary thoroughfares. While there would be less disruption in Layout 3, the additional cost of 1.8 million dollars does not appear justifiable. Layout 2, which greatly reduces construction interference, increases the cost of Phase IV by 3.4 million dollars but reduces future costs by 2.5 million. This results in a net increase of $900,000. Additional cost savings could result if the 600 sewer on Church street were constructed using open cut techniques rather than tunneling. It was suggested that the project be bid with the alternate to provide detailed cost on both of these options. It is anticipated using open cut construction would reduce costs by $700,000. Margaret Wold made a motion to approve the design work of Phase Iv as described in Layout 2. The motion was seconded by Alderman Holsman. The motion was unanimously approved. Phase V - Desicn Uodatq Tom Rowlett described the area approved for design of Phase V. He explained that in order to reduce the impact of continual construction in the area, Staff had requested HES review alternatives which would allow completion of construction in this area and eliminate the need to come back later to finish. The alternative would eliminate the need for further construction east of Lincolnwood Avenue. This results in an increase in the Phase V costs by 1.4 million dollars but a reduction of future costs of 1.3 million dollars or an overall increase of $100,000. Margaret Wold made a motion to approve alternatives proposed for the design of Phase V. Alderman Holsman seconded the motion. The motion was unanimously approved.

It was decided the orientation would be held on August 25, 1993 at 7:00 p.m There being no further business, the meeting was adjourned at 9:10 p.m. Respectfully submitted, Richard J. F3urelli `DRAFT, NOT APPROVED' MIIQUTES OF FLOOD AND POLLUTION CONTROL COWaSSION N'OVEMBER 17, 1993 Members Present: Alderman Jon Holsman, Acting Chair Margaret Wold David Urban Jonathan Fiske Members Absent: Alderman Joe Kent, Ned Lauterbach Staff Present: David H. Barber, Director Public Works David Stoneback, Water & sewer Department Regina R. Steuben, Water & Sewer Others Present: Richard Persaud, Harza Environmental Services (HES) Dan Gallagher, (HES) Thomas Rowlett, (HES) The Flood & Pollution Control Commission met on November 17,1993 in Room 2402 at the Civic Center. The Chair called the meeting to order at 7:05 P.M.. The minutes of the July 21, 1993 were unanimously approved. PROGRESS UPDATES - CONSTRUCTION PROJECTS Dan Gallagher, HES, provided the Commission with status reports on the construction progress in each Phase of the Long Range Sewer Improvement Program (see attached memorandums). Phase 1, Basin S03 is complete. Surveys were sent to 466 residents in the basin. Results are currently being tabulated. 190 surveys have been returned and it appears at this time that only two locations have had basement sewage backups since the project completion. One of the locations has a definite problem with the downspout configuration which is being addressed. The second location of basement backup will be further investigated. Mr. Gallagher summarized the project status for the three areas included in Phase II. The DiPaolo contract in Area 1, the northern section of the city, is approximately 90% complete. The open cut sewer is installed and restoration is underway. The contract for Area III, in the southern portion of the city is virtually complete with the streets and curbs completed. FPCC MINUTES November 17, 1993 Page 2 Phase II - A CA 2 - Marino Construction Mr. Gallagher described the location of the Area 2 contract. This work involves the dropshaft construction at Main Street and the North Shore Channel and the construction of the tunnel from the Channel to Dodge Avenue on Main St. and on Dodge Avenue. Currently this contract is approximately 50% completed. (see attached status report). The major portion of work remaining involves the construction of the 120 inch tunnel on Main street and the dropshaft construction at the Channel. Mr. Barber handed out a revised construction schedule for the Marino contract work. He stated that the problem has been with the piece of tunnel on Main Street. Since October 29th the project has been moving forward well. PHASE III, MAIN ST . COMBINED $9TSR REHAB Mr. Gallagher briefly summarized the combined sewer project on Main Street. He explained the project involved the replacement of a 100 year old brick sewer which was beyond repair. The sewer has been installed and restoration is approximately 60% complete. (see attached status report). MA SB III - CONTRACT -B- Tom Rowlett, HES, described the work included in Contract B which primarily involves the construction of a tunnel on Main Street and relief sewers tributary to the Main Street tunnel. J. F. Shea was awarded the contract on this job and is approximately 4% complete. Construction to date has been limited to the dropshafts at Crown Park and Sherman/Main Street. pESIGN IIPIiAT#i Phase IV Tom Rowlett discussed the status of the design of Phase IV of the sewer system improvements. He stated that the easement with Martin Luther King Lab School was currently being negotiated with a conclusion anticipated in thirty to sixty days. The completion of the plans for Phase IV is estimated for December, 1993. Mr. Rowlett next discussed the sewer construction on Church Street included in Phase IV. He summarized the discussion at the last meeting at which time it had been decided to try to design the sewer construction using tunneling techniques rather than open cut methods to limit disruption to the area. He informed the committee that they had found there is insufficient space to place dropshafts for tunneling without major disruption to existing utilities. The only feasible alternative is to construct the sewer using open cut methods along the sidewalk to allow for traffic flow. This alternative would require restoration to the area. The degree of landscaping and restoration is currently under consideration and Mr. Rowlett asked for Committee input on the amount and type of design to include in the project. He introduced Dick Hayden, a land design consultant to Harza, who has developed three alternatives for the restoration design of this area. FPCC MINUTES November 17, 1993 Page 3 Phase v-Desian i)adate Wont) Mr. Hayden described the three conceptual design layouts for the Church/Dodge streetscape. Concept "A' included the removal of all sidewalk pavements and the installation of new unit paver surfacing and PCC sidewalks at an estimated cost of $243,600. Concept 'B' included the removal of sidewalk pavement on the south side of Church Street only and the installation of new unit paver surfacing to match the current north side of the street. The estimated cost of Concept 'B" was $101,300. Concept "C' involved the complete removal of all sidewalk pavements on both sides of the street and replaced with new sidewalk (no tree grates or pavers) at an estimated cost of $150,600. Mr. Barber stated that he proposed meeting with the Church/Dodge business district similar to the process that took place on Main Street. Construction of this area is anticipated in the summer of 1995 or 1996 outside of the normal school year. The decision of which type of land design to incorporate in the area does not have to be made right away but had wanted to inform the committee of changes in the original design of the sewer on Church Street. Mr. Rowlett next showed slides of some of the existing slate curbs in the Phase IV area of construction. He noted that there are homeowners who are adamantly opposed to the loss of slate curbs. However, during the construction process it is nearly impossible to prevent the loss of the curbs as slate deteriorates under impact. The total replacement cost for slate is approximately $50 to $70 per square foot versus $12 foot for concrete. Margaret Wold made a motion not to try to save and replace slate curbs in the interest of costs. David Urban seconded the motion. The motion was unanimously approved. Phase V - Desian Update Tom Rowlett described the area approved for design of Phase V and commented that the design was proceeding on schedule. The major decision currently underway in the design process is what type of construction to use for the continued tunnel on McDaniel. The two alternatives are jacking pipe versus rib and lagging method. The rib and lagging method was used during the construction of the existing tunnel on McDaniel. This worked well due to the ability to place the dropshaft at Emerson and McCormick. The major difference in the two methods is that Jacking is less expensive and involves several dropshafts. However each shaft remains open for a much shorter period of time, approx. sixty days. In contrast, the rib and lagging method is more expensive, involves fewer dropshafts but the shafts remain in operation throughout the entire length of the project. In the case of the construction on McDaniel, the rib and lagging method will result in the intersection of Payne and McDaniel closed for at least 170 days. For this reason, Mr. Barber recommended the project be bid specifying the use of jacking for the tunnel construction to spread out the disruption to the residents. It was suggested that the situation be discussed with Alderman Moran to get his input. FPCC MINUTES November 17, 1993 Page 4 XEPA UPDATE Mr. Barber summarized for the committee the information obtained from his recent visit to Springfield regarding the availability of low interest loan funds for the remaining phases of the sewer project. The Sewer System Facilities Plan and the phases of the project were originally designed to match the cost of the phases with anticipated monies available from the IEPA. The funding parameters for the IEPA have changed somewhat since that time and the facilities plan needs to be updated to better determine the amount of work remaining, number of phases, and time schedule. It appears that little money will be available in 1994, however, funding availability in 1995 should vastly improve. Therefore, it is recommended not to do Phase IV and V this year and to see what may be available from the IEPA in 1995. We also want to time the update of the Facilities Plan with the submission of design of Phase IV and Phase V. Mr. Barber requested Committee approval to take to Council the proposal from Harza to update the Facilities Plan at a cost of $15,000. Margaret Wold moved approval. Jonathan Fiske seconded the motion. The motion was unanimously approved. 1994 CALENDAR OF NEETIWs& The 1994 calendar of meetings was accepted into the record. The next FPCC meeting will be January 19, 1994. There being no further business, the meeting was adjourned at 9:25 p.m.. Respectfully submitted, Regina R. Steuben
