He explained that his purpose tin coming before the Council was to get permission for the YBSD to perform a Sanitary Sewer Evaluation Survey (SSES). He had asked the City to partner in the study however Director Dhuse explained to him that funds for the study are not in the city's budget. He explained that the YBSD has appropriated funds and would bear the cost of the study. He reported that the worse sewers in the area are south of the river along Route 47 which was evident after the heavy rainfall on September 13 and 14th. The YBSD pumped and treated 13 million gallons which is over their usual amount after the rainfall. Mr. Pfister explained that the YBSD has plans to build a new addition in the future which would include a bridge over the Blackberry Creek. The study is needed in order for the YBSD to obtain funding for the addition. He proposed an intergovernmental agreement between the city and the YBSD which will benefit both parties. John French from Walter E. Deuchler Associates, Inc. accompanied Mr. Pfister and distributed information on the SSES study (see attached) and explained what takes place with it. Mayor Burd stated that she appreciated YBSD's offer to foot the cost of the study and felt that this would be a great opportunity for the city and YBSD to work together. PUBLIC WORKS COMMITTEE REPORT Cannonball Estates — Alice Avenue Storm Sewer (PW 2008 -127) Alderman Besco reported that the subject storm sewer pipe was damaged during construction. Staff has been monitoring the sewer to see if it has changed in the last year and it has not. There are several options that can be applied to the damaged pipe. He turned the floor over to City Engineer Wywrot to go over the options. Mr. Wywrot explained that the pipe could be left alone, which is not recommended; the pipe could be lined at an estimated cost of $7,000.00 or the entire pipe could be dug up and replaced. He explained that the affected piece is a 37' long piece of 12" concrete pipe that runs under Alice Avenue (formerly Faxon Road) near Cannonball Trail. It is not cost effective to line the pipe and it would be a better value to replace it. There is a one year warranty period for the pipe which was accepted by the city knowing that the pipe would be re- evaluated at a later date. Allen Norton, the developer, addressed the City Council. He described what caused the damage and explained that while the project was still under construction, he was given instructions by Mr. Wywrot not to excavate the pipe. He stated that the pipe was televised and chemical grout was applied. He feels that the pipe which has been in the ground for eight years is sound. Last fall, he offered to replace the pipe however Mr. Wywrot indicated that the city did not want to saw cut the new road. Later, Mr. Wywrot informed him the road could be saw cut and the repair made. Mr. Norton indicated that he has tried numerous times to get this repair accepted by the city and stated that he would be willing to put money aside so that the city has it if the sewer fails in the future. Alderman Werderich asked for an explanation of what occurs when the road is saw cut which Mr. Norton provided. Alderman Spears asked what the cost would be for Mr. Norton to excavate and repair the damage. Mr. Allen indicated it would be a few thousand dollars. Alderman Spears clarified that Mr. Norton was offering to give the city the money to cover the repair. Mr. Norton stated that this was correct. Alderman Spears asked Mr. Wywrot if he would be satisfied with getting the money to fix the sewer if and when it fails. Mr. Wywrot clarified that this was the first he had heard of this offer and thought it might be a good solution. Alderman Allen asked if he could see an invoice for the cost of grouting the pipe. Mayor Burd noted that the discussion was not about re- grouting the pipe but rather replacing it for about $2,000.00. Alderman Werderich stated that the photos provided of the pipe look bad. Mr. Wywrot explained that currently the street does not show signs that the sewer is deteriorating. He explained the construction of the pipe and the grouting process which seals the pipe but does not add structural strength. Director Dhuse added that if the developer contributes to the cost of a future repair, the city could waive the warranty. He felt that $2,000.00 seemed a reasonable amount. Administrator McLaughlin also agreed with the offer. There was further discussion on the road saw cut; how the damage was caused; etc. It was the consensus of the City Council that Mr. Norton's offer was an acceptable solution to the problem. The Minutes of the Regular Meeting of the Citv Council — September 23, 2008 — uaee 3 Mayor Burd entertained a motion to accept Allen Norton's offer of a non - refundable $2,000.00 to be deposited with the city in anticipation of the pipe failure. So moved by Alderman Munns; seconded by Alderman Spears. Motion approved by a roll call vote.
