Moon Marsh page 3 Rural Zone Shoreland: (sewered, nonriparian lot) PUD with common septic Proposed PUD lot size minimum 10,800 25,000 sf 33,000 sf to 93,000 sf lot width 80' 100' 250'+ along private road building setbacks from street rear lot line side lot line from OHWL bldg. height 10' 10' 150' 35' 36' 25' same as zoning at project periphery 25' from private road 30' 15' 500'+ per underlying reqs. impervious max. 65% 30% <20% (estimated) min. open space 50% 51% Shoreland: Shoreland overlay zoning covers land within 1000 feet of the Ordinary High Water Level (OHWL) of Rondeau Lake, classified as a "natural environment lake ". A shoreland overlay also applies within 300 feet of Rice Creek, but the creek is about 500 feet to the east. The OHWL for Rondeau Lake has not been determined. Lacking a specific determination, examination of the treeline often is used as the alternative method. The treeline is 100 -150 feet west of the road. By this reckoning, the Wessel property is within the shoreland overlay. However, shoreland requirements will have little effect on the site. Since all the proposed home sites are on the eastern part of the property, shoreland setbacks from the OHWL will not affect the proposal. The nearest building site will be more than 400' from the public roadway, well beyond the required 150' setback from the OHWL. There are no lakeshore lots, so visibility from the lake is not an issue. The shoreland ordinance was written well before current community septic systems technology, so lot sizes addressed only individual septic systems and municipal utilities. The current technology treats wastewater better than the typical public treatment plant. We are considering the "sewered" lot size in the shoreland ordinance as the appropriate one. There are no steep slopes on the property, so erosion down a bank into the lake or anywhere else is not a significant issue. In fact, very little site disturbance is proposed on the western part of the site. The ends of the private loop road and some culvert work are the only excavation activities near East Rondeau Lake Road. The site drains into Rice Creek and then to Peltier Lake and the chain of lakes, so water quality issues are pertinent. There are rain gardens designed into the project. The City has requirements for minimizing erosion that apply to all construction projects. In addition, the Rice Creek Watershed District examines and regulates impacts on wetlands and water quality. We forwarded the initial submittal to the MnDNR in January. An e -mail from MnDNR states they have no concerns and have the following comments:
