Category IV wetlands provide the lowest level of function and are often heavily <br />disturbed, but still provide important functions. Category IV wetlands include: <br />a. All wetlands that score nine to fifteen points on the Wetland Rating Foran—Western <br />Washington. <br />SECTION 3: Subsection A of Section 1 I of Ordinance 2909-06 (EMC 19.37.110), which reads <br />in part as follows: <br />Standard wetland buffer width requirements. <br />A.

The following <br />minimum buffers of native vegetation shall apply to all other wetlands based upon the <br />wetland category and score for habitat functions from the Wetland Rating Form <br />Western Washington. Buffers shall be measured from the wetland boundary delineated as <br />required by Section 37.090.A of this chapter. <br />a. Category II and III wetlands scoring less than nineteen points for habitat function <br />shall have the following buffers: <br />b. Category I, II, and III wetlands that score nineteen or more points for habitat shall <br />have the following buffers: <br />Habitat <br />Category <br />Category <br />21 <br />22 <br />II <br />III <br />25 <br />26 <br />wetlands <br />wetlands <br />29 <br />Buffer Width <br />75 <br />60 <br />b.

Category IV wetlands that score twenty or more points for habitat shall have a <br />minimum buffer width of forty-four feet. <br />2. Required Mitigation. <br />a. For wetlands that score moderate or high for habitat (twenty points or more for the <br />habitat functions), the following criteria must be met: <br />i. When feasible, a relatively undisturbed vegetated corridor at least one hundred <br />feet wide must be protected between the wetland and any other priority habitats as <br />defined by the Washington State Department of Fish and Wildlife ("relatively <br />undisturbed" and "vegetated corridor" are defined in questions H.2.1 and H.2.2 of <br />the Washington State Wetland Rating System for Western Washington, Revised. <br />Priority habitats include: <br />7 <br />
