® Occurrence of special natural resources (i.e. rarelendangeredlthreatened plants and animals, <br />rare natural communities) <br />® Minimal bounce (i.e. no more than one foot in 10-year storm) <br />® Existing adjacent park or open space <br />® Adjacent to WMO-managed water body <br />® DNR-protected <br />® Water bodies that are XX (5, 10, 25, 50??) acres or more in surface area <br />® Receives stormwater runoff from more than one city <br />® Connected to other water resources and/or natural communities (greenway corridor) <br />It may be difficult to decide which wetlands should be WMO-managed with the limited amount of <br />information available. The National Wetlands Inventory can be used as the initial inventory of <br />wetlands in the WMO; either the cities or the WMO can do a complete inventory at a later date. The <br />DNR's county biological survey can be used as a preliminary tool to identify special natural <br />resources. The city surface water management plans can be used to determine the "bounce," surface <br />area, and DNR-protected status for those wetlands included in the cities' hydrologic models. The <br />city watershed information will allow us to determine which wetlands receive stormwater from more <br />than one city. The city land use maps can be used to determine if wetlands are located adjacent to <br />parks or other open space. A combination of all of these sources will be needed to determine <br />whether the wetland in question is part of a larger natural corridor/greenway. Based on all of this <br />information, the WMO will likely be able to group wetlands into three categories: <br />• Definitely WMO-managed <br />® Maybe WMO-managed <br />® Definitely not WMO-managed <br />wetland_class.doc Page 3 09/29/99 <br />
