Project Number: SL-3
The BCWMC approved the 90% design plans at its February 2015 monthly meeting. The City of Golden Valley's consultant, Barr Engineering Company, completed contract documents for the project on May 21, which was the bid advertisement publication date. The Golden Valley City Council awarded the contract on July 7, 2015, to Sunram Construction. The pre-construction meeting was held July 30. Mobilization commenced November 11 and construction started on November 24. The baffle was installed and fully deployed on December 10,2015, and the contractor demobilized from the site for the season. In spring 2016 the contractor will perform final clean up and any necessary site restoration.
The estimated cost of this project is $612,000 of which $78,000 will be funded by the BCWMC's Capital Improvement Project Closed Project Fund and up to $534,000 will be funded by the BCWMC's 2013 ad valorem tax levy collected via Hennepin County in 2014.
The BCWMC, in cooperation with the City of Golden Valley, constructed the Schaper Pond Diversion Project in December 2015 to reduce the amount of phosphorous entering Sweeney Lake.
In 2011 the BCWMC completed the Sweeney Lake Total Phosphorous Total Maximum Daily Load Study (TMDL). The study's implementation program identified modifying the water flow through Schaper Pond as one of the options toward the goal of reducing Bassett Creek Watershed phosphorous loads.
The Schaper Pond Diversion Project diverts water, via a floating water baffle, within Schaper Pond to direct more of the water flows to the northwest part of the pond. The diversion allows the water to remain in the pond for a longer period of time, allowing a greater amount of sediment, phosphorous, and other suspended solids to settle out before the water exits the pond. The project included the installation of an approximately 380-foot floating water baffle extending out from the east side of the pond and the construction of two maintenance access areas. The project is expected to reduce the amount of phosphorus reaching Sweeney Lake by an estimated 81 - 156 pounds per year.
