Planning Case 572-99 Date of Report: October 21, 1999 Project Summary: Jeffrey Hofstede, property owner of 7638 Silver Lake Road, has requested that the City approve a wetland buffer permit to allow for development within the 100-foot buffer surrounding the wetland that encroaches onto his property. Mr. Hofstede proposes to construct a single family home and driveway on his property. Regulatory Background: The City reviews all development that occurs within wetlands and their buffers because of the important role that wetlands play in maintaining the ecosystem and the area hydrology, in that they are critical to the present and future health, safety and general welfare of the land, animals and people within the City. Any existing and potential development within the City and the Rice Creek Watershed pose increasing economic and ecologic demands, potentially despoiling, polluting or negatively altering wetlands and their contributory function and benefit to the City. According to Chapter 1010 of the Municipal Code relating to the Wetland Zoning District, any work occurring within the 100-foot buffer surrounding a wetland requires approval of a wetland buffer permit. Analysis: The City Engineer has reviewed the plans and finds that in terms of the distance from the wetland and the potential impacts of the additional stormwater runoff, the wetland itself would not be adversely affected so long as a minimum five foot natural buffer is retained to surround the wetland to provide for additional filtration of runoff. It was further noted that the stormwater from the home be directed away from the wetland to allow for the runoff to be absorbed into the lawn areas instead of being guided directly to the wetland. In addition, the driveway should be constructed with enough of a slope to direct runoff to the north, away from the wetland.
