City of Arden Hills – 2040 Comprehensive Plan <br /> <br /> <br />Approved:, 2018 <br />13-3 <br />13.1.2 Sanitary Sewer (Appendix E) <br /> <br />The entire City of Arden Hills is within the Metropolitan Urban Service Area <br />(MUSA), therefore sanitary sewer interceptor and treatment is provided to the <br />City via the Metropolitan Council Environmental Services (MCES) system. <br />Within the City, the system is under the jurisdiction of the City’s sanitary sewer <br />utility. Historically, the sanitary sewer utility has managed to be self-supporting; <br />with future infrastructure replacement needs financed from revenues generated <br />from the fees paid by users. <br /> <br />The Arden Hills sanitary sewer system consists of approximately 49 miles of <br />sanitary sewer, over 1,150 manholes, and fourteen (14) lift stations. <br /> <br />The Metropolitan Council Environmental Services (MCES) Water Resources <br />Policy Plan includes policies for reducing inflow and infiltration into the region’s <br />sewage treatment system. The MCES has projected significant growth in the <br />metropolitan area by 2040. This increase, along with current levels of inflow & <br />infiltration (I/I) in the system, would require significant, costly increases to expand <br />the existing MCES treatment facilities to meet the future wastewater flows. As a <br />result, MCES has implemented an I/I Surcharge Program. <br /> <br />Communities with excessive I/I are required to develop plans and reduce their I/I. <br />If I/I is not reduced in the community with excessive I/I, the MCES will impose a <br />surcharge. The City of Arden Hills was identified as a community with excessive <br />I/I and assessed a surcharge in 2007. That year, the City initiated an I/I <br />identification program and has since completed flow monitoring, smoke testing, <br />televising, manhole rehabilitation, sump pump inspections, sewer ling, and sewer <br />replacement. The City will continue these efforts to monitor and reduce I/I. <br /> <br />Appendix E contains general sanitary sewer information and also outlines the <br />City’s objectives, policies, strategies and implementation plan to reduce I&I. <br /> <br />13.1.3 Stormwater/Surface Water Management <br /> <br />With nearly 550 acres of water across seven lakes, numerous wetlands, and <br />Rice Creek, protecting water quality and managing stormwater is of the utmost <br />importance in Arden Hills. As part of the City’s water quality goals, the City <br />recognizes the need to establish a plan that is in conformance with the plans and <br />regulations adopted by the Rice Creek Watershed District and the Metropolitan <br />Council’s 2040 Water Resources Policy Plan. <br /> <br />Dr <br />a <br />f <br />t <br /> <br />11 <br />/ <br />2 <br />0 <br />/ <br />2 <br />0 <br />1 <br />7
