In addition to regulating building setback, building width, <br />and minimum lot size, the DNR also limits the amount of <br />impervious surface on each lot to 30% of the total lot area. <br />This impervious surface must be at least 50' from the river <br />and screened by natural material. <br />Regulations within the Critical Area corridor are set by the <br />Environmental Quality Board (EQB). All land uses within <br />this area are subject to their standards regarding lot size, <br />setbacks, and building heights. Map 5 shows that within the <br />Ramsey Critical Area Corridor there are two different dis- <br />tricts: Rural Open Space and Urban Developed. The EQB stan- <br />dards for these two different districts are expressed in <br />the following table. <br />Table 4 <br />EQB STANDARDS <br />Rural Open Space Urban Developed <br />Lot Size 5 ac ( unsewered only) 5 ac (unsewered only) <br />Height 35' 35' <br />Setback (building 1 <br />roads) <br />Bluffliue 100' 40' <br />High Rater Mark 200' 100' <br />The Wild, Scenic, and Recreational River (WSRR) regulations <br />are the most restrictive of any discussed here. Designation <br />of a river as part of the WSRR system is limited to those <br />rivers or segments of rivers which are thought to have out - <br />standing scenic or recreational value. It has been deter- <br />mined that the Rum and Mississippi rivers, as they pass through <br />Ramsey, meet this critera. The land use provisions in the <br />DNR's rules and regulations differ for the Mississippi and <br />the Rum rivers. In addition, a portion of Rum has been <br />classified as Urban, and the remainder Rural, which necessi- <br />tates enforcement of two sets of standards there. <br />Tables 5 and 6 indicate the DNR's minimum land use standards <br />required along the Rum River. <br />Table 5 <br />WSRR STANDARDS FOR 111E RUM 111VEN <br />RURAL AREA OVERLAY DISTRICT <br />ZONING CONSIDERATIONS <br />Minimum lot size above ordinary high water level <br />Lot width at building line <br />Lot width at ordinary high water level <br />Building setback from ordinary high water level <br />On -site sewage treatment system setback <br />from ordinary high water level <br />Maximum structure height.* <br />Controlled vegetative cutting area (See Section <br />(1) setback from ordinary high water level <br />(2) .setback from bluffline <br />31 <br />STANDARDS <br />4 acres <br />250' <br />250' <br />150' <br />100' <br />35' <br />150' <br />30' <br />This requirement shall not apply to buildings used primarily <br />for agricultural uses. <br />• <br />• <br />
