Does the site have the potential to improve water quality? <br />S 1.1. Characteristics of the average slope of the wetland: (a 1% slope has a 1 ft vertical drop in elevation for every <br />100 ft of horizontal distance) <br />❑Slope is 1% or less points = 3 <br />1 <br />❑Slope is > 1%-2% points = 2 <br />❑Slope is > 2%-5% points = 1 <br />❑Slope is greater than 5% points = 0 <br />S 1.2. The soil 2 in below the surface (or duff laver) is true clay or true organic (use NRCS definitions): Yes = 3 <br />INo = 0 1 <br />0 <br />S 1.3. Characteristics of the plants in the wetland that trap sediments and pollutants: <br />Choose the points appropriate for the description that best fits the plants in the wetland. Dense means you <br />have trouble seeing the soil surface (>75% cover), and uncut means not grazed or mowed and plants are higher <br />than 6 in. <br />❑Dense, uncut, herbaceous plants > 90% of the wetland area points = 6 <br />6 <br />❑Dense, uncut, herbaceous plants > % of area points = 3 <br />❑Dense, woody, plants > % of area points = 2 <br />❑Dense, uncut, herbaceous plants > A of area points = 1 <br />Does not meet any of the criteria above for plants points = 0 <br />Total for S 1 Add the points in the boxes above <br />Rating of Site Potential If score is:_12 = H /(6-11 = M _0-5 = L <br />Record the rating on the first page <br />S 2.0. Does the landscape have the potential to support the water quality function of the site? <br />S 2.1. Is > 10% of the area within 150 ft on the uphill side of the wetland in land uses that generate pollutants? <br />1 <br />Yes=1 No 0 <br />S 2.2. Are there other sources of pollutants coming into the wetland that are not listed in question S 2.1? <br />0 <br />Other sources Yes = 1 No - 0 <br />Total for S 2 Add the points in the boxes above <br />1 <br />Rating of Landscape Potential If score is: V 1-2 = M 0 = L <br />Record the rating on the first page <br />S 3.0. Is the water quality improvement provided by the site valuable to society? <br />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 <br />0 <br />303(d) list? Yes = 1 No = 0 <br />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 <br />0 <br />on the 303(d) list. Yes = 1 No = 0 <br />S 3.3. Has the site been identified in a watershed or local plan as important for maintaining water quality? Answer YES <br />0 <br />if there is a TMDL for the basin in which unit is found. Yes = 2 No = 0 <br />Total for S 3 Add the points in the boxes above <br />0 <br />Rating of Value If score is:-2-4 = H 1 = M /0 = L Record the rating on the first page <br />Wetland Rating System for Western WA: 2014 Update 11 <br />Rating Form - Effective January 1, 2015 <br />
