Comrnunity LL-P3 <br />Storm Pond <br />Qualitative Rank: High <br />Area: 0.9 acres <br />This pond is located near the southeasterr� edge of Langton Lake. A 42-inch RCP and a <br />24-inch RCP, both on the south end of the pond, provide stormwater inputs. The large <br />parkinj lot to the east contributes surface runoff ta the pond. The outleT for the pond is <br />through a 12-inch RCP with a wood weir, near the northwest end of the pond. Over the <br />outlet pipe is a riprap spillway. <br />The pond t�as stecp sloped banks but does have a narrow band of emergent vegetation. <br />Somc emergents on the edge inciude: river buIrush, soft stem bulrush, arrowhead, and <br />cattail. There were also macrophytes such as coontail and duckweed. A border of sandbar <br />willow, vervain, and swamp milkweed forms a buffer along the edge. The pond is visible <br />from the boardwalk, walking path, and nearby businesses. <br />The water was reiatively clear and only had a faint brown color. The clarity could he <br />attributed to the fact it had not rained for four weeks prior to the �eld visit. Redwing <br />blackbird, great blue heron, catbird, and other song birds where observed usin� the pond. <br />The pond sapports a good diversity of other animal life also. Small fish, frogs, aquatic <br />insects (dra�onflies, damselflies, pand skimmers), and deer and raccoon tracks where all <br />observed. The diversity is probably due ta the �roximity to the lake and woods of the <br />park. <br />The National Wetland Inventory map indicates this basin was excavated in an upland <br />area. The pond appcars to bc functioning well for stormwater treatrnent and retcntion and <br />providinb habitat. <br />Rescrvoir Woods <br />For a map of storm ponds within Central Park, please refer to Figure b.8 in the prcvious <br />section_ <br />Ciry af Roseville <br />Parks Natrrral Resotrrce NfanRgel��e�at 159 <br />
