Michael Goodkind Staff Present: Stephen T. Pudloski, Director of Public docks Richard J. Figurelli, Supt. of Water i Sewers James Tonkinson, City Engineer The meeting was called to order at 6:00 P.M. The Chair stated that we could not approve the minutes of November 13, 1905 without a quorum, but she had not seen the need for any corrections. Downspout Disconnection Program Status report was accepted. The Chair noted that the program was near completion and reminded staff to inform the Commission when the Appeals Board finished its work so that proper recognition can be given. Sewer Construction - 1986 Steve Pudloski discussed the sewer TV report on streets to be resurfaced in the 1986 Motor Fuel Tax (M.F.T) street program, following a policy of T.V. inspecting sewers in all streets that are to be resurfaced or repaved. The sewer work or repairs necessary on these streets have been included in the resurfacing contract. This refurfacing program will be presented to the City Council on March 24, 1986 for approval and includes $444,000 worth of sewer work. The budget report for sewer improvements and repairs was discussed. The 7425.50300 account has a budgeted amount of $660,000 and funded by reve-mue from the Northwest Water commission. The 7420.50300 account is $100,000 for emergency repair of sewers that are in danger of collapse. Projects will be funded from both accounts. Foster Street is a re -surfacing project with sections of sewer about to collapse. Case Street is a re -surfacing project and the whole sewer is in bad shape and in need of replacement. Elmwood and Hawthorne Lane are unpaved streets to be paved by special assessment. Both have sewers in very poor condition. Funds have been set aside for the sewer to be replaced. Maple Avenue in Downtown 11 was not originally included in the budget. There is about $549,000 of sewer construction with 5480,000 to be funded from the Capital Development Bond Funds and the remainder from sewer funds. The water mains will cost $108,000 and will be funded from water Bond Funds. The water and sewer funds will be reimbursed by Tax Increment Bonds. The Chair asked when the project would be started and if there was to be traffic disruption. Mr. Pudloski reported the work would commence about April 15, with Emerson being closed for approximately four weeks to construct a connecting chamber at Emerson and Maple. Mr. Pudloski responded to an question by Alderwoman Warshaw of how the Downtown II sower design is going to increase the cost of utilities. He explained the original estimate did not assume detention of storm water and that large diameter pipes would be put under the service drives to detain roof drain and run off water before it enterAd the combined sewer at a controlled release rate. Lonq-Range Sewer plan Mr. Pudloski discussed the program as outlined in the project budget memo. He noted that $200,000 was budgeted according to the plan approved last year. The $170,000 budgeted last fiscal year was not expended and could be reprogrammed if we approach the estimated expenditure of $268,000 for this fiscal year. Mr. Pudloski discussed the projects reported on the fact sheet including TV contracts 1, 2, and 3. He explained the need for a tunnel inspection consultant to ascertain the condition of the large diameter sewers. These sewers are the main trunk lines and because they are the largest size we can put in those streets and are very expensive to replace, they will probably not be replaced. The Chair asked what would happen if they were not in good shape. Mr. Pudloski stated the consultants would recommend how they can be repaired. We are now in the process of writing requests for proposals. Emerson Street sewer cleaning is necessary to get rid of heavy sediments of up to 30" in the S foot diameter sewer so that it can be inspected. Cleaning of these sewers, and in particular the Emerson Street sewer, should have an immediate beneficial effect. The hiring of two temporary people, an Engineering Aide 11 and a Maintenance Worker II, are necessary for the physical inspection and collection of data on the sewer system. Engineering services expenditures listed are to get help front consultants to do analysis. We are investigating the purchase of a computer sewer maintenance program to keep track of all the maintenance done on J the sewers. we are now in the process of updating and doing a physical inventory of all the sewers, cleaning, and TVing. We want, and need, to put all that information in a computer program format to start maintenance records so that every time we do something on that sewer we can add that information and have a good record of that sewer. The $20,O00 shown in the budget includes the software and to load the data related to our system. We are looking at several available and we will write request for .proposals. we have also shorn atemporary Clerk II to enter the information. We have a proposed schedule for fact finding which we hope to complete in a four year period. This is an ambitious program but it should help the in-house prople to become very familiar with the system. Mr. Pudloski reported on the meeting he and Jim Tonkinson had with the Metropolitan Sanitary District (MSG). He stated that with their information we had begun to develop a design philosophy. The philosophy is to use the capacity that the MSD is providing rather than a 2-year, 5-year, or 10-year storm as the limiting factor. Another point was that MSD has in essence said they would allow larger outfalls into the channel for sewer overflows greater than the capacity of the deep tunnel. J Mr. Pudloski stated we had probably underestimated the amount of analysis necessary to design the needed changes to the sewer system and we would need to re-evaluate whether we should buy a computer program or hire a consultant to help with the analysis. Mr. Pudloski suggested that staff prepare a one year status report of the program for the Council. The Committee agreed and directed staff to draft the report and forward it to the Committee for review. Chair adjourned the meeting at 6:55 P.M. eAl OCLI*ba�rd J Lii4fte 14 i MINUTES OF FLOOD AND POLLUTION CONTROL COMMISSION September 17, 1986 Members Present: Alderman Margaret Wold, Chairman Alderman John Bleveans Aldermen Roberta Warshaw Dr. Jerry Handler Members Absent: Alderman Beth Davis Dr. Michael Goodkind Ms. Sherry Bradford Staff Present: Stephen T. Pudloski, Director of Public Works Richard J. Figurelli, Supt. of Water & Sewers James Tonkinson, City Engineer David Stoneback, Asst. Supt./Operations-Water & Sewei James Wolinski, Asst. Supt./Administration Water & Sewers The meeting was called to order by Chairman Wold at 8:03 P.M. The minutes of November 13, 1985 and March 19, 1986 were approved as submitted. Downspout Disconnection Program Mr. Wolinski reported that except for a few court cases pending the program was completed. tie then summarized the program and gave the following facts: 10,000 buildings came under the ordinance of which 5,151 owners applied for a variance. These variance applications involved about 26,044 downspouts of which 10,750 were granted. The total program looked at approximately 51,290 downspouts of which 40,385 are now disconnected. This is 79% disconnected and the remaining 21* receiving variances. There were 13 tickets issued to appear in court for failure to disconnect and 10 of these homeowners complied. The 3 that did not comply also did not appear in court and judgments of $200 apiece were levied against the owners. We are currently working with the Legal Department to resolve the problem and force compliance. There were 12 tickets issued for concrete capping violations, 10 of which have now met compliance and 2 have been given extensions of time until October 10 by the court. We still have 5 homes that have absentee owners who we have been unable to contact as yet. The Legal Department is pursuing this matter. Alderman Bleveans asked to have this information summarized and sent to the Council. The Chair asked staff to prepare this memo and also directed staff to invite the Review Board to the Council meeting on the night that the memo is presented to thank them for their work. Mr. Wolinski also conveyed the feeling of the Review Board to stay in existence for the full three-year term in the event any new appeals are filed. The Commission agreed and extended their appreciation to staff for their work on this project. Sewer Construction - 1986 Mr. Tonkinson reported we had two contracts this year, the Downtown II sewer in Maple Avenue and the resurfacing and replacement of sewers in Maple (Foster to Noyes), Case Street, Foster Street, Hull Terrace, and Lake Street. The sewer replacements on both these contracts is completed and the resurfacing is virtually completed with the exception of some restoration work. The Downtown II project costs amount to $636,897.32 with the State refunding $403,453.18 from the Capital Do vvlopment Bond Funds. The Chair asked how the sewer repairs and replacements were identified on the streets to be resurfaced. Mr. Tonkinson and Mr. Pudloski explained the investigation procedure which included TV'ing the sewer lines prior to resurfacing. Alderman Hleveans asked how much more sewer work would be required in Downtown II. Mr. Pudloski responded that the Maple Street sewer from Emerson to Clark represented about 10% of the work which will include storm water storage. Long Range Sewer Plan 1. Status of Fact Finding Team. Dav-e Stoneback handed out a fact sheet showing the progress of the Storm Water Inundation Mitigation (SWIM) fact finding team. They have completed their investigations in drainage Basins B06, B02, B03, B03A, Bll, B12, and B13 and 95% of their work in B07. The fact finding team has completed the investigation of approximately 50% of the sewers. Basins BOB, B082, and BO? are the basins left to be investigated and are scheduled to be completed in 1988. In addition to this work, the Engineering Department has investigated and recorded the condition and function of drainage basin outfall structures in all but three basins. Mr. Pudloski explained that essentially the fact finding was a physical inventory of what is actually there, to obtain accurate elevations of flow lines, manhole inverts, and sewer sizes. 2. T.V. Inspection and Sewer Cleaning Mr. Stoneback reported on TV Contract 1, 2, and 3, Emerson Street sewer cleaning, and large diameter sewer inspection. T.V. Contract No. 1 included light cleaning and TV inspection in Basins BO1, B04, B04A, B05 and streets scheduled to be resurfaced in 1986. National Power nodding Corporation completed the contract which included 61,579 feet of sewer main at a total cost of $34,302.80. -2- TV Contract No. 2 included light cleaning and TV inspection of Basins B03, B03A, and B06. Wolf Equipment Corporation was awarded the contract for the lump sum cost of $26,250.00. Wolf began the inspection work for this project on May 7, 1986. As of the contract completion date, June 30, 1986, Wolf had completed only 25% of the 51,535 feet of sewer to ter inspected. During a review of the inspection reports, for the work that Wolf had completed, we found several inaccuracies that made the reports useless to the City. Due to Wolf's poor performance his contract was terminated. The City is now taking action to enter into a contract with National Power Rodding, the second low bidder for a lump sum cost of $31,951.70, to undertake this contract. TV Contract No. 3 included heavy cleaning and TV inspection in Basins Bll, B12, and B13. The City Council approved the low bid of $34,605.00 by National Power Rodding on June 9, 1986. National Power Rodding has indicated that they will start the inspection of the 57,675 feet of sewer in this project on September 15, 1986. it is assumed that National Power Rodding will complete this work prior to the November 30, 1986 completion date. The contract to clean the combined sewer in Emerson Street from Orrington to Ashland was awarded to National Power Rodding Corporation on April 14, 1986 for the cleaning of 3,938 feet of 72", 60" and 36" of combined sewer pipe in Emerson Street for the lump sum cost of $50,000.00. National Power Rodding began the sewer cleaning shortly after the City obtained the required waste generator's permit in early July. National Power Rodding had completed the cleaning of 327 feet of 36 inch combined sewer and approximately 870 feet of 60 inch sewer pipe when the brick manhole at the intersection of Emerson Street and Asbury Avenue beqan to fall apart. At this time the entire manhole structure has failed causing a void under the concrete road surface. National Power Rodding has pulled off the job site and has stated that they will not continue the contract work until such time that Evanston has inspected the remaining manholes and can assure them that the manholes are structurly sound. The City is currently obtaining repair cost estimates from five construction companies to repair this damaged manhole. Large Diameter Sewer Inspection The four engineering firms which responded to our request for proposal, to conduct a walk-through inspection of 11,550 feet of 54 inch and larger sewers, were interviewed. On July 17, 1986, -3- the City Council approved the proposal by Alvord, Burdick & Howson to complete the inspections for the lump sum cost of $39,000.00. This inspection work is tentatively scheduled to begin by September 1, 1986. Mr. Stoneback also reported that request for proposals were sent to 12 firms for a Sewer Maintenance Management Program which is a computer software program with associated hardware. This program will provide an inventory of the sewer infrastructure and keep records of all maintenance, inspections, and repairs of the sewer system. It will also provide maintenance scheduling and be utilized to formulate the long range sewer plan. Four firms returned request for proposals which are now being looked at by staff. Mr. Stoneback handed out fact sheets showing expenditures to date on all contracts. Work Program - Year 2 Mr. Pudloski reported the work was progressing according to the schedule provided. He explained the process of investigation being pursued and the importance of completing the analysis of the information before proceeding to establish a long range sewer plan. The analysis will be slightly behind schedule, but the fact finding will be completer] ahead of schpdulp. We have gotten some proposals to help do the analysis and they arp more expensive than we thought they would be. We are looking at getting our own sewer analysis program to be coupled to the sewer maintenance program to do our own analysis. We will then begin looking at alternatives in the northwest side basins where the TV inspections will be complete and where most of the unimproved streets'are located. This will give us an opportunity to design some detention into these streets. We are going to propose expending $300,000 for the analysis, fact finding and TV inspections next year. The original plan called for spending $170,000 the first year and then $200,000 each following year. We did not expend the $170,000, so we will request the $300,000 which will put the planned expenditures back on schedule. This money all comes out of the Northwest Water Commission revenues which we expect to be two million dollars. This will leave aproximately 1.4 million dollars for the sewer program after operating expenses. We will use $300,000 for analysis, which will leave approximately 1.1 million dollars to do sewer construction. The sewer construction we will be doing are the emergency repairs we find from the TV contracts, the work we need to do under the streets we are resurfacing, and work we need to do under streets we have programmed for special assessments. We can expect approximately 1.4 million dollars annually from Northwest Water Commission water sales now that they are fully on line. -4- The Chair discussed the meeting schedule and the Commission decided to continue the present practice of scheduling to meet on the third Wednesday every other month, but would meet on an as -needed basis with notification to the members, Chairman Wold adjourned the meeting at 9:20 P.M.
