Title
Resolution to Authorize Acquisition of Easements for the LynAnne-Arbana Sewer Project (aka Huron West Park Sanitary Sewer, Phases 2 and 3) (8 Votes Required)
Memorandum
The sanitary sewer line in this project area was constructed in the 1920s to serve the northwest portion of the City. During 2016 and 2017, the City of Ann Arbor undertook the Sanitary Sewer Improvements Preliminary Engineering (SSIPE) Project to evaluate capacity constraints in the sanitary sewer system during projected wet weather conditions. To alleviate capacity constraints, and reduce the potential for sanitary backups into basements, the SSIPE Project concluded that this segment of sanitary sewer should be replaced with a larger diameter sewer. The sewer is situated predominantly in rear yard easements and City parkland from Arbana Dr. to Lyn Anne Ct, between Dexter Ave. and Linwood Ave. The total length of this segment is approximately 4,300 feet (0.8 miles). The work will consist of a total replacement of the sewer line in this segment.
Permanent and temporary easements must be obtained before beginning the sewer replacement work. Additional easement area is required to accommodate the replacement and upsizing of the sewer. Existing easements are too narrow or, in some cases, recorded easements have not been located. The path of the new sewer will be substantially the same as the existing sewer, therefore it is expected that easement acquisition will not substantially affect residents' current use of their properties. Because of the public necessity for these easements to continue to provide sanitary sewer service, this resolution authorizes the City Attorney to initiate condemnation proceedings if necessary to obtain the easements.
Staff has conducted public engagement with affected property owners to inform them of the nature of the project and the need for easements. Two neighborhood Zoom meetings were held last year to present project background, description, and answer quest...
