projected sewer flows in turn provide the basis for sizing future sanitary sewer extensions and improvements. Based on the review and planning for the 2030 Comprehensive Plan, the previous development densities were modified. Table 1 provides a summary of the maximum allowed densities from Table 5-3 in the Comprehensive Plan, the projected average net densities of development between 2008 and 2030 from Table 5-7 and the average density goals from page 5- 10. Low Density Residential Medium Density Residential High Density Residential Maximum Gross Density from Table 5-3 (units/acre) 4 Table 2.1 Residential Density Table Projected 2008- 2030 Net Density from Table 5-7 (units/acre) 3 7 6 15 12 Average Density Goal (units/acre) 3.0 6.0 7.0 It is standard engineering practice to use conservatively high densities in projecting future sanitary sewer flows to ensure that facilities have adequate capacity for the ultimate sewer flows. Therefore, the study uses the projected 2008-2030 net densities from Table 2.1. The proposed policy for the Rural Developing land use category, the largest land use in the City, includes enforcing a maximum density of one unit per 2.5 acres and also developing, implementing and enforcing a septic system inspection program and wellhead protection program. In other words, the Comprehensive Plan anticipated that areas in the Rural Developing land use areas will be serviced by on -site systems. The Comprehensive Plan includes a Special Area Plan for an area along 167th Avenue between TH 47 and CSAH 5 as shown on Item H in the Appendix. With the exception of the most westerly 40 acres, this area is not included in the 2030 MUSA. However, the City intends to City of Ramsey Page 2-5 Comprehensive Sanitary Sewer Plan - 2012 Prepared by Bolton & Menlc, Inc.
