Alternative designs ~i!l be evaluated for each proposed co~.~Lmunity septic system. Design alternatives may include, but not be limited to, standard drainfields, sand filters with standard drainfields, multiple mound systems, alternating seepage beds with pressure distri- bution of effluent, tuck system (methanol mediated nitrate reduction to nitrogen gas), sand filters with surface discharge, extension of sanitary sewer se~,ice to the affected area. The selection of an appropriate septic system design ~iL1 be based on soil suitability, groun~ water effects (mounding, contamination), area requirements, surface discharge requirements, etc. Cost analysis will include assessment of the projected e;[tensicn date of Dub!ic se~ices, ~ ~ any, to the subject area. A City of Ramsey pe-~mit will be required for installation of any comr. unity .septic system. If average daily flow exceeds !0,000 · gallons, a permit from ~[PCA is required as well. As part of the ldPCA permit, monitoring wells are required. The City of Ramsey may re~aire monitoring or other septic system performance data on systems producing less than !0,000 gallons per day. In short, while a regional rural preservation policy may be laudibie and indeed workable in some outlying areas of the metropolitan region, it makes little sense to apply it to a community %,here nearly 75% of the land area outside the I.~SA is currently developed. There is not an extensive rural character to maintain. There is little agriculture which can be expected to continue. Lastly, there is no physical or environmental basis for restricting development due to sewage disposal requirements for !0 acres of land. At the same time,'the City recognizes that' long te,--m~ low density development (2.5 acre lots) such as is occurring in Ramsey and in neig.hboring cor~munities can be more e>~ensive than t)~ical urban settings. This is due to demands for some urban level services such as parks developmen%, streets, fire protection even though these costs must be distributed over much lower population densities.
