Projects consist of both water quality improvements and flood control. The SWWD continues to look for opportunities to partner with Cities, Townships and County's on projects to improve water quality throughout the watershed. Discussion In 2012 there are 3 major projects in the East Mississippi Management Unit, including ravine stabilization, stormwater control structures, and water quality /habitat improvements. These three projects are in various stages of construction design and planning. Ravine stabilization in Newport includes ponding, storm sewer, channel stabilization and water quality improvements. The project will also include local flood damage reduction to alleviate local drainage issues. The Clear Channel Pond Project will provide water quality improvements and flood control along Highway 61 and between Cottage Grove and St. Paul Park. The Grey Cloud Island Project will restore flow to the Mississippi River backwaters around Grey Cloud Island to improve water quality and habitat. In the South Washington Management Unit design is beginning on the watershed overflow. This project has been in the planning stage for nearly 20 years. This project will be partnered with Washington County and the City of Cottage Grove and carry excess stormwater runoff from the northern watershed to the Mississippi River. Total project cost is estimated at $20 million. Other projects will include Cottage Grove Central Ravine improvements, CSAH 19 upgrades, and city street reconstruction projects. In 2012 the first implementation projects for the lower St. Croix Management Unit will occur since the boundary expansion in 2010. The SWWD is working with the Washington Conservation District to reduce phosphorus loading to Lake St. Croix as part of the States Total Maximum Daily Load (TMDL) for the St. Croix River. Several sites have been identified to implement best management practices in the form of grassed waterways, sediment basins, pond retrofits and bioretention areas. The SWWD also received two Clean Water Legacy Grants in 2011 to accelerate our implementation efforts to improve water quality in two sub - watersheds. The SWWD will be Honorable Mayor, City Council, and Ryan Schroeder Page 2 of 2 working on water quality improvements in the Trout Brook watershed. The work will primarily consist of stream bank stabilization, sediment reduction and nutrient reductions. The second grant will focus on water quality improvements in the Colby Lake sub watershed. This grant will be used to add water quality treatment in cooperation with the City of Woodbury street reconstruction to reduce phosphorus loading to the lake. Total the SWWD received $239, 000 in clean water grants. In June of 2011 the SWWD submitted to the Minnesota Pollution Control Agency a category 413 Demonstration to achieve water quality standards in replace of a TMDL. The SWWD continues to work with the State to develop a mechanism to capitalize on the local government implementation framework to achieve water quality standards. Requested Action The South Washington Watershed District (SWWD) Board is requesting time to make a brief presentation to the Council on March 7, 2012. The purpose of our request is to highlight and answer questions concerning watershed activities. SWWD staff and board members will provide very brief overview of these topics and be available to answer questions.
