City of Arden Hills – 2030 Comprehensive Plan <br /> <br /> <br />Approved: September 28, 2009 <br />E-4 <br /> <br />4. MCES SEWER VOLUME FORECAST <br />The MCES has estimated wastewater flows for Arden Hills based on the <br />Metropolitan Council’s population, housing and employment forecasts, and <br />historical community flow data. This information was provided from the MCES in <br />the 2030 System Statement and is shown below in Table E.3. These numbers <br />were not adjusted as a part of this Comprehensive Sewer Plan Update. <br />Projections for 2030 indicate an average annual wastewater flow of 1.47 mgd. <br /> <br /> Table E.3 – MCES Sewer Volume Forecast <br />Year 2010 2020 2030 <br />Sewered Population 11,200 13,500 15,200 <br />Sewered Households 3,800 4,600 8,000 <br />Sewered Employment 15,200 17,100 20,000 <br />Average Annual Wastewater <br />Flow (MGD) 1.28 1.47 1.47 <br />Allowable Peak Hourly <br />Flow (MGD) 3.84 4.41 4.41 <br />Note: This data is from the Metropolitan Council 2030System Statement provided to Arden Hills <br />as part of the September 2009 Comprehensive Plan Update. <br /> <br />5. LAND USE AND ZONING <br />This update has been prepared considering the City of Arden Hill’s current <br />zoning and land use maps. A copy of the current zoning map, existing land use <br />map, and 2030 future land use map is included as Figures E.2-E.4 respectively. <br />For the purposes of estimating sewage flows, we have assumed the following: <br /> 2010 sewage flows are based on actual meter records provided by the MCES. <br /> The existing land use map compares well with the current zoning map and is used to <br />illustrate 2015 development within the City. <br /> The 2030 land use map in conjunction with the TCAAP Master Plan is used to illustrate <br />projected 2030 development within the City. <br /> <br />6. SANITARY SEWER SERVICE DISTRICTS <br />The City is divided into eighteen (18) primary sewer districts comprised of the <br />following: Lift Station Districts LS 1- LS 14, Gravity Districts MCES 54 & MCES <br />59, and TCAAP Districts North and South. Additionally, the sewered portion of <br />the Arden Hills Army Training Site (AHATS) discharges via a private forcemain <br />into MCES 59. The district boundaries included in this update are consistent with <br />the boundaries identified in the 2009 update with the exception of the addition of <br />two new sewer districts in the TCAAP area. A map illustrating these boundaries <br />is attached as Figure E.5. <br /> <br />7. PROJECTED SEWAGE FLOWS
