5.3 INVE.VTORY AiND ASSESSMENT OF WETLA.NDS <br />5.3.1 Wetland Inventory <br />As stored eofiier. the City's objective is to protect, enhonce. ord/or <br />wthn 20 feet of a oroposed or exsting stormwater outlet pipe were <br />inventoned end mopped os port of the SWMP. This inventory c'so served <br />os the base of information for development of other ports of the wefond <br />management plan. <br />5.3.2 Stormwater Susceptibility Assessment <br />^ Gu/ctonce For Evaluating Urtxjn Storm Water and Snowmett Runoff <br />Impacts To We//onds was the source materia: for rating a wetlond's <br />susceptibility to runoff. Potential Impacts ossoadted with storm and <br />meltw(^er runoff Include fluctuation in water levels (bounce) within the <br />wefl<^d. the durotion of Inundation at the varying bounce elevations <br />'^oter being directed to the wetland. A given ' <br />wetlo^ s susceptibility to runoff Is dependent on the wetland type, end <br />the charocterlstjcs orxj quality of its plant community. <br />As on example, o sedge meadow, which likes a particular hydroioo c <br />wet meadow with c variety of grosses end flowers's more sensTtive then <br />eorh nMh Susceptibility rating foreach of the evaluated wetlands Is Indicated by coior-coding on tne <br />system map. The rotlrgs described in the guidance document ere <br />•> Highly Susceptible <br />❖ Moderately Susceptible <br />« Slightly Susceptible <br />❖ LeostSusceptible. <br />Further tfacusSon on susceptibility and ossodofed wetland communiv <br />descnptlons. modlied from the Guidance For Evaluating Urban Starrn <br />Water and Snowmelt Runoff Impacts To Wetlands, is presented In <br />Ap^ndx H. Each susceptiblity rating category describes different <br />wetland types, including plant communities and hydrology. <br />OtyofOnno
