EN HILLS <br /> MEMORANDUM <br /> DATE: May 17, 2010 <br /> TO: Honorable Mayor and City Council Members <br /> Patrick Klaers, City Administrator - <br /> FROM: Kristine Giga, Civil Engineer <br /> SUBJECT: Sanitary Sewer Repair-Venus Avenue Easement <br /> Background/Discussion <br /> Staff has identified a sanitary sewer repair that is needed on the main that is located parallel <br /> to the Elmer L. Andersen Trail Connection south of Venus Avenue. This was brought to the <br /> May 10 City Council meeting for discussion. Staff obtained quotes from three contractors, <br /> which were not yet available at the time of the meeting. The agenda item was tabled to May <br /> 17, so that the City Council could evaluate the quotes and select an alternative. <br /> Quotes were obtained for two alternatives. One alternative is to replace the main line in its <br /> current location. This alternative will require the removal of the large cottonwood trees <br /> directly over the existing sanitary sewer. The second alternative is to construct a new sewer <br /> line around the large trees by constructing two new manholes. The main line would have a <br /> jog, which is less desirable from a maintenance perspective, but would minimize tree <br /> removal. Some smaller trees and undergrowth would need to be removed, but the large <br /> cottonwoods would be saved. Attached are photos of the area, as well as the figure showing <br /> the needed repair. <br /> Financial Implications <br /> A summary of the quotes received is attached. The lowest quote was provided by American <br /> Liberty Construction, Inc., who is the contractor for the Elmer L. Andersen Memorial Trail <br /> Connections project. The quote provided to remove the cottonwoods and replace the sanitary <br /> sewer in place is $4,700. The quote to realign the sanitary sewer and leave the cottonwoods <br /> in place is $9,890. These quotes are significantly less than staffs estimates. <br /> The cost for this repair will be paid for using Sanitary Sewer Enterprise Funds. $40,000 is <br /> included in the 2010 budget for maintenance of utilities; to date, $3,807.73 has been spent. <br /> Council Action Requested <br /> Authorize staff to contract with American Liberty Construction, Inc., to make necessary <br /> repairs to the sanitary sewer main along the easement off of Venus Avenue. <br /> Provide staff direction for the preferred alternative. <br /> City Council Meeting <br /> 11Metro-inet.uslardenhills\PR&PW1EngineeringlCouncil_Actions1201015-17-I OMemo_VenusSewerRepair.doc <br /> Page 1 of 1 <br />
