CITY COUNCIL AGENDA ITEM 6B STAFF ORIGINATOR: Diane Hankee, City Engineer MEETING DATE: June 27, 2016 TOPIC: Consider Resolution No. 16-62, Accepting Feasibility Study, NE Area Drainage Study VOTE REQUIRED: 3/5 INTRODUCTION Staff is requesting council acceptance of the feasibility study for the NE Area Drainage Study. BACKGROUND The City Council authorized preparation of a feasibility study for the NE Area Drainage Study on September 14, 2015 to provide surface water management to land lying north of Main Street between the City of Hugo and Peltier Lake. The surface water in the northeast area of Lino Lakes is landlocked inhibiting site improvements within this area. The area has been historically landlocked until the installation of agricultural field drains in the early 20th century. These agricultural drains are now at capacity and are incompatible with future development within the watershed. In addition the agricultural drains do not provide water quality benefits to the receiving waterbody, Peltier Lake. A majority of this watershed currently drains to the south via field drains to Clearwater Creek. Clearwater Creek is impaired for aquatic life and has had a history of significant bank erosion problems. Multiple alternatives were considered and refined with input from land owners, potential developers, neighboring communities, the Rice Creek Watershed District (RCWD), the Minnesota Department of Transportation and the Minnesota Department of Natural Resources. As a condition of the project, a Comprehensive Surface Water Management Plan (CSMP) is in development. The CSMP and the associated surface water modeling includes regional water quality best management practices (BMPs), stormwater volume and rate control improvements, and a new outlet to Peltier Lake. The CSMP also includes design standards for future developments in the Northeast area. Peltier Lake is impaired for nutrients and it is imperative that the new system does not adversely impact the lake and other downstream interests. The proposed project will benefit nearly 1,300 acres and includes: • A new stormwater conveyance system; • Multi-purpose regional stormwater management facilities;
