CITY OF ST. ANTHONY VILLAGE WATER RESOURCES MANAGEMENT PLAN SECTION 4 Page 1 4. ASSESSMENT OF PROBLEMS AND ISSUES Outlined below is an assessment of existing and potential water resource-related problems that are known at this time. These problems have been identified based on an analysis of the land and water resource data collected during the preparation of this plan and through information provided by the City, its residents, and the watershed organizations. A description of any existing or potential problem within the City has been listed and potential future corrective actions have been incorporated into an implementation plan. Refer to Figure 7, Appendix A for the location of many of the problem areas discussed below. 4.1. Water Quality Problems Problem 4.1.A There are concerns regarding water quality, sediment deposition and floatable material entering Silver Lake from direct storm sewer discharges. Silver Lake has been listed as impaired by the MPCA due to excess nutrients and mercury in fish. Corrective Action 4.1.A The City will work with the RCWD, Ramsey County SWCD, Three Rivers Park District, and the cities of New Brighton and Columbia Heights to implement improvements consistent with the Silver Lake Total Maximum Daily Load (TMDL) implementation plan. The City will continue to implement a catch basin stenciling program within the Silver Lake drainage area. The City has recently implemented water quality improvements upstream of Silver Lake, including the Salo Ponds and Apache redevelopment. In addition, the City has completed an alum treatment system in Salo Ponds (2014) and is participating in an ongoing carp removal program (first removal was winter 2013-2014). As of 2017 the City is very near achieving its TMDL waste load allocation and is planning on fully achieving this during the course of this plan. Problem 4.1.B The Mississippi River just south of the City has been listed as an impaired water for fecal coliform, mercury, and polychlorinated biphenyl (PCBs). In addition, Lake Pepin has been listed as impaired for excess nutrients. These regional water body impairments will affect upstream communities. Corrective Action 4.1.B The City partnered with the MWMO to complete the St. Anthony Regional Stormwater Treatment System in the right-of-way of CSAH 88 near the border of Minneapolis. The project provides treatment to 602 acres of previously untreated land prior to discharging it to the Mississippi River. The City will also continue to work with the MWMO, MPCA, and others as necessary to integrate monitoring data, public works activities, and educational opportunities to address the completed TMDLs and implementation plans. Problem 4.1.C The City anticipates that there may be additional, future impaired waters listed that will affect the City. Corrective Action 4.1.C The City will work with the RCWD, MWMO, MPCA, New Brighton, and others to develop and implement future TMDLs that affect the City.
