Kittitas County Shoreline Master Program <br />b. Category ll wetlands: Category ll wetlands are difficult, though not impossible, to <br />replace, and provide high levels of some functions. These wetlands occur more <br />commonly than Category I wetlands, but still need a relatively high level of <br />protection. Category ll wetlands include: <br />i. Forested wetlands in the floodplains of rivers; <br />ii. Mature and old-growth forested wetlands with native fast growing trees; <br />iii. Vernal pools; <br />iv. Wetlands scoring between nineteen and twenty one (1 9-21) points (out of <br />twenty seven (27))in the Eastern Washington Wetland Rating System. <br />c. Category lll wetlands score between sixteen and eighteen (16-18) points (out of <br />twenty-seven (27)) in the Eastern Washington Wetland Rating System and can <br />efternoften be adequately replaced with a well-planned mitigation project. <br />Wetlands scoring between 16-18 points generally have been disturbed in some <br />ways, and are often smaller, less diverse and/or more isolated from other natural <br />resources in the landscape than Category ll wetlands. <br />d. Category lV wetlands have the lowest levels of functions, scoring less than <br />sixteen (16) points in the Eastern Washington Wetland Rating System, and are <br />often heavily disturbed. These are wetlands that should be able to be replaced, <br />and in some cases improved. These wetlands may provide some important <br />functions, and also need to be protected. <br />G. Requlations-wetland buffers <br />1. Buffer widths: Buffers shall be established and maintained to protect all regulated <br />wetlands. Standard minimum buffer for wetlands are listed in Table 5.2-1. The buffer <br />shall not be altered except as authorized by this Program; provided, that such <br />alterations meet all other standards for the protection of regulated wetlands. Buffers <br />are measured horizontally in all directions from the regulated wetland edge as <br />marked in the field. <br />Table 5.2-1.
