City of Arden Hills – 2030 Comprehensive Plan <br /> <br /> <br />Approved: September 28, 2009 <br />13-7 <br /> <br />The City is committed to adopting plans, policies, and tools that effectively <br />advance the City’s, RCWD’s, and regional water quality goals. As part of <br />LSWMP update, development reviews, regulatory updates, and other related <br />policies, the City will work to address the following issues: <br />o Formally adopt criteria to protect and improve stormwater runoff and <br />quality, such as the Nationwide Urban Runoff Program (NURP); <br />o Require stormwater plans for new development and redevelopment <br />that requires increased stormwater infiltration and a decreased use of <br />impervious materials; <br />o Identify and adopt best management practices that reduce stormwater <br />runoff, such as the Metropolitan Council’s Urban Small Sites Best <br />Management Practice Manual; <br />o Where feasible, require pre-settlement stormwater discharge on new <br />developments and redevelopments; <br />o Identify and adopt methods for minimizing the effects of temperature, <br />especially for streams and wetlands; <br />o In cooperation with the RCWD, collect water quality data on lakes <br />within the City and establish goals for each water body; <br />o Educate residents on the link between surface water and ground water <br />quality; and, <br />o In cooperation with the RCWD, complete a wetland management plan; <br /> <br /> <br /> <br />13.1.4 Inflow and Infiltration (I&I) <br /> (Appendix G) <br /> <br />The Metropolitan Council Environmental Services (MCES) Water Resources <br />Management Plan includes policies for reducing inflow and infiltration into the <br />region’s sewage treatment system. The MCES has projected significant growth in <br />the metropolitan area by 2030. This increase, along with current levels of inflow <br />& infiltration (I&I) in the system, would require significant, costly increases to <br />expand the existing MCES treatment facilities to meet the future wastewater <br />flows. As a result, MCES has implemented an I&I surcharge program. <br /> <br />Communities with excessive I&I are required to develop plans and reduce their <br />I&I. If I&I is not reduced in the community with excessive I&I, the MCES will <br />impose a surcharge. The City of Arden Hills has been identified as a community <br />with inflow and infiltration (I&I) challenges. The MCES has imposed a surcharge <br />on the City as a part of its I&I reduction program. Based on current readings that <br />the MCES has taken from several monitoring points, Arden Hills’ surcharge is
