Newell,P.E., City Engineer`�,��/ SUBJECT: Kaydon Drive Relief Sewer, City Project 2003-10 SUMMARY RECOMMENDATION: An item on the agenda for the June 16, 2003, City Council Meeting is the authorization of an agreement for design services with Bainbridge, Gee, Milanski &Associates, Inc. (BGM) for a fee not to exceed $9,400 to design a relief sewer for the Kaydon Drive area sewer system. Staff recommends that the City Council approve the attached agreement. BACKGROUND: In February of 2002, the City Council approved an agreement with BGM to study the sanitary sewer system serving the Kaydon Drive area. The attached drawing shows the sewer service area studied. The Kaydon Drive sanitary sewer system covers an area that extends from Franklin Street Road on the east, the Illinois Central Rail Road on the west and Imboden Drive on the north. For many years, sanitary sewer backups and overflows have plagued the homes on Kaydon Drive and regular sewer overflows occur on Imboden Drive near Medial Drive. These overflows have caused sewage to back up into private homes and into nearby drainage ways. It is paramount that the City aggressively address sanitary sewer overflows and strive to identify and correct problems as they occur. The BGM study recommended that the main sewer line serving the area be cleaned and derooted. The City has issued a chemical derooting project that includes this area and should assist in keeping the lines root free. BGM's second recommendation was to extend a relief sewer across the railroad tracks and tap into a sewer line on the west side of the tracks that has excess capacity to contain the overflows.
