To verify that past assumptions are still appropriate, City staff reviewed the land use <br />planning assumptions that were identified in the 1991 Comprehensive Sewer Study. Based on <br />this review, development densities have been modified to reflect current land use planning <br />efforts. The major change from previous planning efforts is the inclusion of various multi -family <br />developments with densities ranging from 7.0 to 15.0 units per acre and a change to the <br />population projection from 3.2 to 3.0 people per unit show in Table ES.1. In addition, based on. <br />current communications with the Metropolitan Council, the City of Ramsey is now considered a <br />"Developing Community" which eliminates the constraints of the MUSA Line. The City of <br />Ramsey can now extend sanitary sewer service anywhere within MWCC's Sanitary Sewer <br />District 3 boundary (south of Trott Brook) as long as the added flows do not exceed the City's <br />current capacity allocation of 3.8 mgd. <br />Based on the design criteria and current land use planning, Table 2.1 provides a summary <br />of the projected sanitary sewer flows for the ultimate service areas north and south of Trott <br />Brook, the Rum River Sewer District, the Mississippi River Sewer District, and the 10 -year <br />growth area. <br />Table 2.1 <br />Sanitary Sewer Flow Summary <br />Description <br />Total <br />Units <br />Total <br />Population <br />Residential <br />Flow (mgd) <br />Comm. / Ind. <br />Flow (mgd) <br />Other/ <br />Special <br />Flow (mgd) <br />Daily <br />Flow (mgd) <br />South of Trott Brook <br />24,710 <br />74,130 <br />5.66 <br />1.59 <br />0.07 <br />7.32 <br />North of Trott Brook <br />8,800 <br />26,400 <br />1.98 <br />0.00 <br />0.00 <br />1.98 <br />Rum River District <br />15,401 <br />46,203 <br />3.46 <br />0.14 <br />0.04 <br />3.64 <br />Mississippi River District <br />9,309 <br />27,927 <br />2.20 <br />1.45 <br />0.03 <br />3.68 <br />Growth 2004 to 2014 <br />13,600 <br />40,800 <br />3.06 <br />City of Ramsey <br />Comprehensive Sanitary Sewer Plan - 2004 Prepared by Bolton & Menlc, Inc. <br />Page ES -2 <br />
