CITY OF ST. ANTHONY VILLAGE WATER RESOURCES MANAGEMENT PLAN SECTION 4 Page 2 In 2014, the City constructed a biofiltration rain garden in Central Park that is designed to remove more than 20 pounds of total phosphorous from runoff per year. This runoff discharges downstream to Pike Lake and Long Lake in New Brighton and Fridley, which are resources of concern. 4.2. Flooding and Stormwater Rate Control Concerns Problem 4.2.A Flooding has occurred in the Anthony Lane Industrial Area. Corrective Action 4.2.A The City has completed a feasibility study to identify options to provide additional flood protection to the Anthony Lane Industrial Area. The City will construct improvements to address this flooding. Problem 4.2.B Limited stormwater conveyance capacity of the downstream storm sewer system through New Brighton has in part resulted in street flooding in the vicinity of 39th Avenue and Fordham Drive, on Foss Road, as well as near the Mirror Pond condos. Corrective Action 4.2.B The City of St. Anthony Village is currently working with the RCWD and the City of New Brighton to address these water quantity problems which transcend municipal boundaries. Refer to the City of St. Anthony Village’s July 2011 Flood Investigation and Stormwater Modeling Report, which outlines the collective efforts towards the resolution of flooding and water quality issues within the subwatersheds of RCD #2, #3, and #5. The City intends to work with the RCWD to investigate options to discharge more flow into New Brighton through RCD #3 to alleviate flooding in the northeast portion of the City. The City intends to investigate modifications to the Remmele culverts in RCD #3 as a potential solution. 4.3. Impacts of Stormwater Management Practices on Recreational Opportunities Problem 4.3.A There is a concern regarding water quality, sediment deposition and floatable material entering Silver Lake from direct storm sewer discharges. Additionally, Silver Lake is listed as impaired for excess nutrients. Corrective Action 4.3.A The City will work with the RCWD and Ramsey County SWCD to develop a feasibility study for Silver Lake which will establish a recommended long-term management program. This study should identify alternatives available for protecting or improving water quality, maintaining reasonably stable lake levels, and outlining a management program that will ensure that proper and reasonable management measures are implemented. The City will cooperate with the RCWD, Ramsey County SWCD, and Three Rivers Park District to complete and implement the TMDL for Silver Lake. 4.4. Impacts of Stormwater Quality on Fish and Wildlife Resources Problem 4.4.A Poor water quality of Silver Lake has impacted recreational opportunities and fish populations. Corrective Action 4.4.A
