I I I I I I I It I I I I I I I , I OVERVIEW OF CITY DRAINAGE PATTERNS The City's subwatersheds are centered around its major lakes which are in turn connected to each other by large wetland complexes, ditches or drainage ways. The Round Lake subwatershed district generally includes the areas between Old Highway 10 and 1-35W north ofI-694. The Arden Manor Mobile Home Park and portions ofTCAAP also drain into Round Lake. The majority of the Gateway Business District does not drain to Round Lake but is routed to a new storm water treatment pond between the Minnesota Commercial Railroad property and 13th S1. NE. This pond discharges into the MnDOT drainage system along 1-35W, which drains into Long Lake in New Brighton. Round Lake overflows to the southeast into a ditch along Old Highway 10, which empties into Valentine Lake. Valentine Lake also receives a large portion of City drainage from a geographical area roughly bordered by County Road E to the South, Lexington A venue to the East, Old Highway 10 to the west and a line approximately 300 feet south of Highway 96 to the north. Valentine Lake also receives runoff from the Valentine Hills area to the west of Old Highway 10 centered on Valentine Lake Road. Valentine Lake overflows to the west under Old Highway JO just north of McCracken Lane into a ditch and wetland complex which extends along County Road E2 and heads north until it leaves the City limits at a weir located near the Valentine Lake Road bridge over 1-35W. This also enters Long Lake in New Brighton via the 1-35W drainage system. Lake Josephine receives runoff from the adjacent lake properties and the neighborhoods around Ingerson Road and Edgewater Avenue extending to Lexington Avenue. A good portion of Lake Josephine is located within the boundaries of the City ofRoseville, which also generates the majority of runoff entering this lake. Lake Johanna receives a very large amount of runoff from Roseville to the south via Little Johanna Lake as well as the overflow from Lake Josephine. In addition, Lake Johanna receives runoff from Arden Hills neighborhoods bordered by New Brighton Road to the west, Lexington Avenue to the east and County Road E1Lake Johanna to the north. Lake Johanna overflows into the wetland complex located in the Ramsey County open space between County Road E and County Road E2 where it joins up with the overflow from Valentine Lake to proceed towards Long Lake. Karth Lake is a land-locked body of water with a relatively small tributary watershed located in the City of Arden Hills. Some high-water conditions have existed on Karth Lake in the past however, a permanent means to regulate the lake level was considered and rejected by the adjacent landowners. Sunfish Lake overflows into Marsden Lake, which drains directly to Rice Creek via a drainage way located within the TCAAP site. The existing properties fronting Highway 96 between Keithson Drive and Lexington Avenue generally drain to Sunfish Lake or Marsden Lake. Rice 3
