South Central Technical Service Area (SCTSA) will use this Clean Water Fund grant to provide Soil and Water Conservation Districts and other local organizations in its eleven-county area with a Geographic Information System (GIS) Technician to assist in using available GIS information to target specific locations where Best Management Practices (BMPs) can be installed to help improve water quality.
This project will install new stormwater treatment practices in neighborhoods directly draining to Coon Lake. The objective is to remove phosphorus, which fuels algae growth, before the water is discharged into the lake. Seventeen potential project sites have been identified and ranked and include curb-cut rain gardens, swales, stabilizing stormwater discharge points, and a basin outlet modification.
This feasibility study will produce strategies for wetland restoration and ditch hydrology changes to reduce the amount of phosphorus and solids that drain into Typo and Martin Lakes, the Sunrise River and St. Croix River. Total Maximum Daily Loads and other plans have identified this area as key for pollutant reduction, and the study will determine scope and effects of potential projects, allowing the district to prioritize those that will have the great impact on water quality.
This project will install an iron enhanced sand filter (IESF) to restore water quality in Golden Lake. Golden Lake is within a fully developed area of the Twin Cities, surrounded by residential land use, and the focal point of a city park. The IESF will achieve 11% of the phosphorus reduction (21 lbs/yr) required for Golden Lake to meet State water quality standards, as identified in the approved Total Maximum Daily Load (TMDL).
This project will install nearly 800 linear feet of restored lakeshore with an emphasis on bioengineering techniques, native plants and locating buffers/swales at points of concentrated overland flow into Green Lake. By targeting properties that are eroding and/or with concentrated overland flow to the lake we will reduce suspended solids discharge by 16,697 lbs/yr and phosphorus by 1.3 lbs/yr.
This Oak Glen Creek stormwater pond expansion and enhancement using an iron enhanced sand filter (IESF) is a partnership between the Anoka Conservation District (ACD) and a private company to protect a downstream corridor stabilization and improve the quality of stormwater discharged to the Mississippi River. Very little stormwater infrastructure currently exists in the 573 acre Oak Glen Creek subwatershed, and it discharges 147,519 pounds of sediment and 353 pounds of phosphorus to the Mississippi River annually.
The Rice Creek Watershed District (RCWD) will create a web-based, mobile-compatible public drainage system inspection and maintenance database. This database system will enable District staff to create and track maintenance requests and inspections from the field, including Geo-referencing locations requiring repair via a mobile device. The system will greatly reduce the time required to identify and log each maintenance request, enabling staff to inventory more miles of public drainage system yearly thereby identifying erosion problems more efficiently and thoroughly.
This project is located in an area in the City of Isanti that developed before modern-day stormwater treatment requirements. It will result in the installation of a new stormwater pond in a historic core neighborhood. The urbanized drainage area presently has no other stormwater treatment, except for street sweeping. The new stormwater pond will reduce discharges from a 55 acre site draining to the State Scenic and Recreational Rum River by 12 pounds/yr for phosphorus and approximately 3 tons/yr of sediment.
