Go to First Page Wetland name or number A SLOPE WETLANDS Water Quality Functions - Indicators that the site functions to improve water quality S 1.0. Does the site have the potential to improve water quality? S 1.1. Characteristics of the average slope of the wetland: (a 1% slope has a 1 ft vertical drop in elevation for every 100 ft of horizontal distance) Slope is 1% or less points = 3 0 Slope is > 1%-2% points = 2 Slope is > 2%-5% points = 1 Slope is greater than 5% points = 0 S 1.2. The soil 2 in below the surface for duff laver) is true clay or true organic (use NRCS definitions): Yes = 3 No = 0 0 S 1.3. Characteristics of the plants in the wetland that trap sediments and pollutants: Choose the points appropriate for the description that best fits the plants in the wetland. Dense means you have trouble seeing the soil surface (>75% cover), and uncut means not grazed or mowed and plants are higher than 6 in. Dense, uncut, herbaceous plants > 90% of the wetland area points = 6 0 Dense, uncut, herbaceous plants > % of area points = 3 Dense, woody, plants > % of area points = 2 Dense, uncut, herbaceous plants > Y. of area points = 1 Does not meet any of the criteria above for plants points = 0 Total for S 1 Add the points in the boxes above 0 Rating of Site Potential If score is:_32 = H _6-11 = M /0-5 = L Record the rating on the first page S 2.0. Does the landscape have the potential to support the water quality function of the site? S 2.1. Is > 10% of the area within 150 ft on the uphill side of the wetland in land uses that generate pollutants? 1 Yes - 1 No = 0 S 2.2. Are there other sources of pollutants coming into the wetland that are not listed in question S 2.1? Other sources Yes = 1 No - 0 0 Total for S 2 Add the points in the boxes above 1 Rating of Landscape Potential If score is:v/ 1-2 = M _0 = L Record the rating on the first page S 3.0. Is the water quality improvement provided by the site valuable to society? S 3.1. Does the wetland discharge directly (i.e., within 1 mi) to a stream, river, lake, or marine water that is on the 303(d) list? Y-es 1 No = 0 1 S 3.2. Is the wetland in a basin or sub -basin where water quality is an issue? At least one aquatic resource in the basin is on the 303(d) list. Yes - 1 No = 0 1 S 3.3. Has the site been identified in a watershed or local plan as important for maintaining water qualit ? Answer YES if there is a TMDL for the basin in which unit is found. Yes = 2 No = 0 2 Total for S 3 Add the points in the boxes above 4 Rating of Value If score is: / 2-4 = H _1 = M _0 = L Record the rating on the first page Wetland Rating System for Western WA: 2014 Update 11 Rating Form - Effective January 1, 2015
