CITY COUNCIL AGENDA ITEM 6A STAFF ORIGINATOR: Diane Hankee, PE, City Engineer MEETING DATE: May 9, 2022 TOPIC: Consider Resolution No. 22-47, Authorizing Lakeview Area Storm Drainage Plan VOTE REQUIRED: 3/5 INTRODUCTION Staff is requesting City Council's authorization to enter into a professional services agreement with WSB and Associates to prepare a Lakeview Area Storm Drainage Plan. BACKGROUND The Lakeview Drainage Area, located on the City's western border with Blaine, is an urban area that drains poorly and does not have a storm sewer system. It is bound by Elm Street, Sunset Avenue, North Road, and Sunrise Drive. This area, which encompasses the Lexington Park and Lakeview neighborhoods, was platted in 1946. In 1987, the City completed a Comprehensive Storm Drainage Plan for a larger area that has been partially implemented. There is still a larger area in the neighborhood that remains to be addressed. City public works staff annually pumps surface water in certain locations during spring thaw conditions. The roadways in this neighborhood are planned to be reconstructed in 2027. This area is currently served by private wells and individual onsite septic systems. Due to the limited lot sizes, the City would coordinate the extension of municipal sanitary sewer and water with the roadway and drainage improvements. As a first step, staff is looking to update the Lakeview Area Storm Drainage Plan to reflect current design requirements, evaluate potential ponding areas, and identify/confirm the preferred storm water routing. The City currently owns two parcels available for stormwater ponding in the area. The City also has open space in Sunrise Park that could be used if necessary. The City will be evaluating if additional area for stormwater management is required. This information would be used for the 2027 Street Reconstruction project planned in this neighborhood. WSB and Associates provided a proposal to complete the study in the amount of $14,400.00. Funding will be provided through the Stormwater Maintenance Fund.
