City of Arden Hills - Comprehensive Plan - DRAFT <br /> Storm drainage is provided throughout the City with a network of storm <br /> sewers, open ditches, holding ponds, which are under the jurisdiction of <br /> the City's Surface Water Management Utility. Similar to the water and <br /> sewer utilities, the Surface Water Management Utility has been designed <br /> to be financially self-supportive for day-to-day operations, ongoing <br /> maintenance, and upgrades. <br /> Arden Hills is in the Rice Creek Watershed District, which is the regulating <br /> authority for stormwater in Arden Hills_ Much of the surface water in <br /> Arden Hills drains towards Rice Creek, which flows southwest through <br /> Anoka and Ramsey County toward the Mississippi River approximately <br /> 1.5 miles north of Interstate 694 in Fridley. Stormwater from Roseville <br /> flows north through Ramsey County Ditch No. 4 into Little Lake Johanna <br /> and Lake Johanna. From there, the water continues north into Long Lake <br /> in New Brighton. Lake Josephine also drains into Lake Johanna. Round <br /> Lake flows into Valentine Lake, which rains into Long Lake. Sunfish Lake <br /> drains into Marsden Lake, which flows into County Ditch No. 1 and drains <br /> into Rice Creek. Although Karth Lake does not have any natural outlets, <br /> a pump station manages the water level and any water pumped out drains <br /> to Valentine Lake through storm sewer and ditch systems. <br /> • Although most of the land south of County Road 96 is developed, not all <br /> areas are served by the City's stormwater system. The City does require <br /> storm sewer to be installed with road reconstruction projects; however, <br /> this policy is not always practical or feasible, and alternate design <br /> standards may sometimes be appropriate. A process to allow alternates <br /> to storm sewer is needed. <br /> The City completed its Surface Water Management Plan, which was <br /> approved by the Rice Creek Watershed District in 2002. The Rice Creek <br /> Watershed District is currently in the process of updating their Water <br /> Resource Management Plan. Once their update is completed, the City will <br /> update the Surface Water Management Plan. <br /> Since a land use plan for the proposed redevelopment of the TCAAP <br /> property has not yet been adopted, the current Stormwater Management <br /> Plan does not yet reflect future stormwater management needs on the <br /> TCAAP property. The Surface Water Management Plan will need to be <br /> updated once a final land use plan for the TCAAP property has been <br /> selected. <br /> DRAFT 87 <br /> 3/14/2008 <br />
