REQUEST FOR COUNCIL ACTION DATE: May 23, 2016 ITEM NO: 9 ______________________________________________________________________________ Department Approval: Administrator Reviewed: Agenda Section: Name Adam Edwards P.E. JML Public Works Director/ Title Public Works Director/City Engineer City Engineer’s Report ______ _______________________________________________________________________ Item Description: Spring Hill Sanitary Sewer Extension ______________________________________________________________________________ List of Exhibits A- Location map showing potential sanitary sewer extension. B- Proposal from Bolton and Menk 1. Purpose. The purpose of this action item is to gather Council direction on extending a sewer main to service lake side properties on Spring Hill Road. 2. Background. The homeowner at 1025 Spring Hill Road, Mr. John Bowlsby has requested the City extend the municipal sewer to service his property. In getting to the property the sewer would pass by 2 other properties 1135 and 1125 Spring Hill Road (See Exhibit A). All of these properties are currently served by private septic systems. All three properties are currently included in the Metropolitan Urban Service Area (MUSA). The nearest city sewer main is a low pressure forcemain that extends to 1145 Sixth Avenue North. 3. Considerations. Staff recommends the Council should consider the following items when providing direction on this item: a. Environmental impacts. Per the Community Management Plan the city will provide municipal sewer extensions to lakeshore areas within the MUSA when it is determined that municipal sewer is preferable to long term use of on-site sewage treatment systems. (2008 CMP, Page 4C-16). Municipal sewer would be preferable in this situation if the lots had failed septic systems with no alternative sites available. The most economical and physically feasible route to run the sewer line is along the lakeshore. While low pressure systems do have a good performance track record, any line breaks would see effluents released in the immediate proximity of Long Lake. b. Community Support. While the project would provide potential service to three properties with the potential to serve a fourth with another extension, currently only one of the property owners is requesting the service. One owner has expressed a willingness to grant an easement to support the project but may not connect for some time and the third has expressed initial apprehension about granting the necessary easement. c. Cost. The estimated cost for the sewer main extension is shown in the table below. In addition, residents that hook up to this main would likely incur costs around $18,000 for the necessary pumps, service lines and installation to their home.
