Sec. 78-1605.-Wetland buffer areas and setbacks. <br /> (a) This subsection establishes autharity far wetland buffer areas around protected wetlands. Buffer <br /> areas are necessary and beneficial to maintain the �ealth of wetiands. Buffer areas protect the edge <br /> of wetlands from erosion whi�e filtering sediment, chemicals an� other nutrients frflm runoff that <br /> drains into wetlands. Buffer areas can improve the biological diversity and health of a weUand <br /> environment while reducang the adverse im�acts of human activities. <br /> (b) All wetlands within the City of Orono are within the Minnehaha Creek Watershed District (MCWD}, <br /> which has rules and regulations for the establishment and maintenance of wetland buffers. In an <br /> effort to avoid overlapping or conflicting regulations, the city defers jurisdicction for the establishment <br /> and maintenance of wetland buffers to the Minnehaha Creek Watershed District. I# application of <br /> MCWD buffer regulations is in conflict with city regulations, the more restrictive requirements shall <br /> apply. <br /> (c) In order to provide for a minimum level of wetland proEection where Minnehaha Creek Watershed <br /> District buffer rules do nat provide for adequate separation between wetlands and buildings or ather <br /> structures or surtacgs, the City Shall require setbacks from the delineated ecige of a protected <br /> wetland as fofiows: <br /> Minimum distance setback from delineated edge of wetland to any <br /> building(principal or accessory)or other structure, hardcover, <br /> septic systems or wells: <br /> �Where no formal buffer exists and <br /> where MCWD does not require a 35 feet <br /> buffer <br /> Where a formal buffer exists or 35 feet or established buffer width plus 10 feet,whichever is <br /> where MCWD buffer is required greater <br /> Areas within the required setbacK area subject to filling, grading or excavation as part of a <br /> construction project shafl be revegetated immediately upon completion of such earthwork. Setbacks must <br /> be verified with wetland delineation information. The determination of whether a Level 1 defineation or <br /> Level 2 delineation is required shall be at the discretion of the planning director. Level 2 delineation <br /> information shall be provided on a certified certificate of survey. The requirement for delineation shalE be <br /> applied in cases where the wetland exists within 150 feet of the proposed project. <br /> (d} The City of Orono has established wetland proteCtion strategies in the Orono Surtace Water <br /> Management Plan (SWMP) (January 2011). A protection classification has been assigned to each <br /> wetland in Orono based on the stormwater susceptibility and functional assessment for each <br /> wetland. The city has also established additional protection requirements for each classification. The <br /> four protection cEassifications are described as follows: <br /> , <br /> � Additional Protection <br /> Protection Susceptibility Description Requirements <br /> �Classification Rating (B= Bounce-Change in <br /> water level due to runoff <br /> Page 2 <br />
