Exhibit B <br />ORDINANCE Exhibit A - Page 30 of 55 <br />may be updated as new wetlands are identified. The exact location of a wetland boundary shall be <br />determined through field investigation by a qualified professional applying the approved federal <br />wetland delineation manual and applicable regional supplements methods and procedures. <br />C. Wetlands shall be rated and regulated according to the categories defined by the Washington State <br />Department of Ecology Washington State Wetland Rating System for Western Washington 2014 Update, <br />or as revised (Ecology Publication No. 14-06-029). Wetlands, as defined by this chapter, shall be <br />classified as category I, category II, category III, or category IV. <br />1. Category I wetlands are those that: (a) represent a unique or rare wetland type; or (b) are <br />more sensitive to disturbance than most wetlands; or (c) are relatively undisturbed and contain <br />ecological attributes that are impossible to replace within a human lifetime; or (d) provide a very <br />high level of function. All wetlands that meet one or more of the following criteria shall be <br />considered category I wetlands: <br />a. Bogs; <br />b. Mature forested wetlands larger than one acre; <br />c. Wetlands that perform a very high level of function as evidenced by a score of <br />twenty-three points or more on the Wetland Rating Form—Western Washington. <br />2. Category II wetlands are ecologically important and provide a high level of function. They are <br />difficult but not impossible to replace. Wetlands that meet the following criteria shall be <br />considered category II wetlands: <br />a. Wetlands that do not meet the criteria of category I wetlands; <br />b. A wetland identified by the State Department of Natural Resources as containing <br />“sensitive” plant species; <br />c. Wetlands with high functions and values as indicated by a score of twenty to twenty- <br />two points on the Wetland Rating System Form—Western Washington. <br />3. Category III wetlands provide a moderate level of functions. They are typically more <br />disturbed, smaller, and/or more isolated in the landscape than category I or II wetlands. <br />Wetlands that meet the following criteria shall be considered category III wetlands: <br />a. Wetlands that score sixteen to nineteen points on the Wetland Rating Form— <br />Western Washington. <br />4. Category IV wetlands provide the lowest level of function and are often heavily disturbed, <br />but still provide important functions. Category IV wetlands include: <br />a. All wetlands that score nine to fifteen points on the Wetland Rating Form—Western <br />Washington. <br />19.37.100 WETLAND CRITICAL AREA REPORT CRITERIA. <br />Repealed by Ord. 3676-19.
