• • Moon Marsh page 8 protected wetland 740W. Wetland #4 in the southeast corner of the Moon Marsh site is part of this complex. The proposal would fill 4200 sf of wetland along the roads and mitigate this with 4200 sf of new wetland and 4200 sf of public value credits in the form of infiltration basins. The design and implementation must comply with RCWD requirements. Drainage and utility easements will be established that cover and extend 10' beyond the wetlands, in accordance with City requirements. Conservation easement locations will correspond to these drainage and utility easements. Two infiltration basins are proposed, one on the north side of the site along the road, one on the south side. Floodplain: The FEMA floodplain map shows much of the site within the 100 -year floodplain. The RCWD has determined the 100 -year elevation to be 887.5. Lowest floor elevations are at least two feet above this in accordance with City policy. There will be minor floodplain fill which will be addressed by excavating an area of equal volume to compensate (compensatory storage). Roads, Access, Traffic: The proposal extends the existing driveway on the south part of the site to become a private loop road with another access onto East Rondeau Lake Road. This private road serves all four lots. Because heavy vegetation can block sightlines, a certain area should be cleared where the loop accesses East Rondeau Lake Road. The right of way for the east 33 feet of East Rondeau Lake Road will be dedicated with the plat. The road is an easement now. This will be clarified with the title search that will be necessary for a final plat. The creation of three new residential lots will not create a traffic generation problem. Park Plan and Dedication: The parks plan shows Natural Resource Protection Areas corresponding to the locations of wetlands as revealed by the wetland delineation. These are wetland areas that will be protected by existing wetland law or may be important plant communities. They will be covered by a conservation easement as well as a drainage and utility easement. The Natural Resource Conservation Areas are uplands with features that have high ecological value. These areas should be examined for the potential for protection. The rare plant survey found no rare species in the uplands on the site, and most of these areas have been disturbed by past use. Park dedication will be cash in the amount of $2075 for each of the three new lots, for a total of $6225.
