Go to First Page Wetland name or number A SLOPE WETLANDS Hydrologic Functions - Indicators that the site functions to reduce flooding and stream erosion S 4.0. Does the site have the potential to reduce flooding and stream erosion? S 4.1. Characteristics of plants that reduce the velocity of surface flows during storms: Choose the points appropriate for the description that best fits conditions in the wetland. Stems of plants should be thick enough (usually> 1/1, in), or dense enough, to remain erect during surface flows. 0 ❑Dense, uncut, rigid plants cover > 90% of the area of the wetland points = 1 ❑All other conditions points = 0 Rating of Site Potential If score is:_1 = M ✓ 0 = L Record the rating on the first page S 5.0. Does the landscape have the potential to support the hydrologic functions of the site? S 5.1. Is more than 25% of the area within 150 ft upslope of wetland in land uses or cover that generate excess 1 surface runoff? Yes = 1 No = 0 Rating of Landscape Potential If score is: ✓ 1 = M _0 = L Record the rating on the first page S 6.0. Are the hydrologic functions provided by the site valuable to society? S 6.1. Distance to the nearest areas downstream that have flooding problems: ❑The sub -basin immediately down -gradient of site has flooding problems that result in damage to human or natural resources (e.g., houses or salmon redds) points = 2 2 eSurface flooding problems are in a sub -basin farther down -gradient points = 1 No flooding problems anywhere downstream points = 0 S 6.2. Has the site been identified as important for flood storage or flood conveyance in a regional flood control Ian? 0 Yes =2 No=0 Total for S 6 Add the points in the boxes above 2 Rating of Value If score is: ✓ 2-4 = H _1 = M _0 = L NOTES and FIELD OBSERVATIONS: Record the rating on the first page Wetland Rating System for Western WA: 2014 Update 12 Rating Form - Effective January 1, 2015
