Cottageville Park Water Quality Protection and Stream Restoration Project
Projects and Practices 2014
This area currently discharges a significant amount of untreated stormwater runoff to Minnehaha Creek. Proposed improvements will treat direct/untreated runoff and allow for re-routing of untreated stormwater on Blake Road and Lake Street to provide large scale water quality benefits. A total phosphorus reduction of 34 lbs to the City of Hopkins is estimated.
This project resulted in estimated reductions of 25 lb. of phosphorus per year and 11 tons of sediment per year
LOCAL LEVERAGED FUNDS
The Cottageville Park Water Quality Protection and Stream Restoration Project was developed to meet the goals of the Minnehaha Creek Watershed District and the City of Hopkins, including; water resource management, channel stabilization, stream enhancement, riparian corridor improvements, open space creation, park development, and revitalization. The project achieves these goals through implementation of the following:
1. Redeveloping a portion of the previously expanded park area to include a wide variety of stormwater BMPs including biofiltration, infiltration areas, stormwater re-use systems, native plantings, and enhanced outlet filters. These practices, when completed, will reduce on an annual basis the pollutant load directed to Minnehaha Creek by approximately 35 pounds of phosphorus, 20 tons of sediment, and 5 acre feet of runoff volume;
2. Stabilizing eroding banks and enhancing the riparian corridor along 1000 feet of Minnehaha Creek;
3. Constructing an education kiosk and creek access within Cottageville Park;
4. Providing recreational opportunities with a canoe/kayak access and connection to the Cedar Lake LRT Regional Trail.
