EXECUTIVE SUMMARY <br />A. GENERAL <br />The purpose for this study is to update the City's Comprehensive Sewer Plans taking into <br />account current population and land use projections. These projections are provided by the City's <br />2030 Comprehensive Plan. The planning period is 2012 through 2031. <br />As with past studies this study does not propose the expansion of sanitary sewers. The purpose of <br />this report is to identify ultimate sewer flows based on current land use planning and identify the <br />approximate location, sizing, and capacity of the trunk facilities needed to serve the 2030 <br />Municipal Urban Service Area (MUSA) as proposed in the Comprehensive Plan. The Plan also <br />presents alternatives for providing sanitary sewer service to the Special Area along 167th which is <br />not currently within the 2030 MUSA but is proposed to be added within the planning period. <br />B. SANITARY SEWER FLOW PROJECTIONS <br />The design criteria used for this report are similar to the criteria used in past reports with some <br />updates based on current planning efforts. Table ES.1 shows the design criteria used for the <br />preparation of this report. <br />Table ES.1 <br />Design Criteria <br />Description Factor <br />Gallons Per Person Per Day 75.0 <br />Flow Variation Factor 2.5 to 4.0 <br />People Per Unit 2.7 <br />Flow Per Unit (Gallons/Day) 202.5 <br />Commercial / Industrial Flow Per Acre (gpd) 1,500 <br />Public Land Flow Per Acre (gpd) 750 <br />City of Ramsey Page ES-1 <br />Comprehensive Sanitary Sewer Plan - 2012 Prepared by Bolton & Menlc, Inc. <br />
