The outfalls are located (from north to south) <br />at 153rd Ave. and Oneida St. (Catchment RR-1), 149t" Ave. and Waco St. (RR-2), 147t" Ln. and Waco St. <br />(RR-3), Waco St. east of 143rd Ave. (RR-4), 142nd Ln south of Waco St. (RR-5), Rivers Bend Park north of <br />the parking lot (RR-6) and south of the parking lot (RR-7), 142nd Ave. (RR-8), and Bunker Lake Blvd. (RR- <br />9). <br />These nine catchments have a wide variety of land uses, including single-family and multi -family <br />residential, commercial, parkland, and industrial. Soils are generally sandy, and range from fine sand <br />loams (Becker series) to coarse sands (Duelm series). <br />EXISTING STORMWATER TREATMENT <br />Catchment boundaries and research areas within the Rum River drainage network were specifically <br />chosen to locate and assess areas which were not already receiving stormwater treatment from <br />constructed ponds and basins or wetlands. Only three existing BMPs were present within the nine <br />catchments modeled. Two of these existing BMPs, stormwater retention ponds P19E304 in Catchment <br />RR-1 and P25216 in Catchment RR-8, treat their entire respective catchments. The third BMP, street <br />cleaning, is provided network -wide across all municipal streets by the City of Ramsey twice per year <br />using mechanical sweepers. Additional detail for each of these BMPs is provided in the respective <br />Catchment ID Pages. <br />City of Ramsey Stormwater Retrofit Analysis <br />
