This project proposes significant improvements to the City of Bloomington's Anti-Icing/Brine making capabilities. The use of anti-icing technology reduces the amount of salt needed to clear snow and ice from city street. The improvements work to address the chloride impairment in Nine Mile Creek and the metro area by reducing the amount of salt applied to the streets and thereby reducing the amount of chlorides entering our surface water systems.
The City of Minnetonka and its residents highly value the water resources within the community, which include approximately ten lakes, four streams, and hundreds of wetlands. The City has been progressive in protecting these resources through policies and management strategies, and now wants to increase their on-the-ground efforts in protecting and improving water quality. The City hopes to conduct targeted watershed assessments for fourteen selected priority water bodies to identify and optimize the type and locations of Best Management Practices (BMPs) to be installed.
The Greater Blue Earth River Basin Alliance (GBERBA) along with Soil and Water Conservation Districts, Counties, landowners, and drainage authorities in the ten member counties will install conservation drainage practices to improve water quality. 103E drainage systems with documented sediment or water quality issues are the focus with the goal of installing 52 practices such as improved side inlets (grade stabilization structures), alternative tile inlets, denitrifying bioreactors, saturated buffers, storage wetlands and others.
Nicollet County is located in south central Minnesota and is bordered on two sides by the Minnesota River. A line of forested bluffs separate the river valley from land that is relatively flat and historically used for agricultural purposes. Approximately 245,000 acres of the County are actively farmed. The 2012 impaired waters list for water bodies located in Nicollet County include the Minnesota River, Seven Mile Creek, Rogers Creek and tributaries to the Rush River.
The objective of the project is to develop a targeted stormwater implementation and outreach program focused on non-profit partners. The Nine Mile Creek Watershed District is a 50 square mile fully-developed watershed with 15 major lakes and over twenty miles of creek system. Given that much development in this area occurred prior to the era of stormwater management regulations, runoff from many sites is untreated prior to discharge to downstream water bodies.
