Kittitas County,WA <br /> § 17A.07.020 CRITICAL AREAS § 17A.07.030 <br /> i. Alkali wetlands; <br /> ii. Wetlands with high conservation value that are identified by scientists of the Washington <br /> Department of Natural Resources Natural Heritage Program; <br /> iii. Bogs and calcareous fens; <br /> iv. Mature and old-growth forested wetlands over 1/4 acre with slow-growing trees; <br /> V. Forests with stands of aspen; and <br /> vi. Wetlands scoring between twenty-two and twenty-seven (22-27) points in the Eastern <br /> Washington Rating System. <br /> b. Category II wetlands are difficult,though not impossible, to replace, and provide high levels of <br /> some functions. These wetlands occur more commonly than Category I wetlands,but still need <br /> a relatively high level of protection. Category II wetlands include: <br /> i. Forested wetlands in the floodplains of rivers; <br /> ii. Mature and old-growth forested wetlands over 1/4 acre with fast-growing trees; <br /> iii. Vernal pools; and <br /> iv. Wetlands scoring between nineteen and twenty-one (19-21) points in the Eastern <br /> Washington Rating System. <br /> C. Category III wetlands have a moderate level of functions and score between sixteen and eighteen <br /> (16-18)points in the Eastern Washington Rating System.These wetlands can be often adequately <br /> replaced with a well-planned mitigation project. Category III wetlands generally have been <br /> disturbed in some ways,and are often less diverse or more isolated from other natural resources <br /> in the landscape than Category 11 wetlands. <br /> d. Category IV wetlands have the lowest level of functions and are often heavily disturbed. They <br /> score fewer than sixteen (16) points in the Eastern Washington Rating System. These are <br /> wetlands that can usually be replaced, and in some cases improved. However, experience has <br /> shown that replacement cannot be guaranteed in any specific case. These wetlands may provide <br /> some important functions and also need to be protected. <br /> (Ord. 2021-016,2021) <br /> § 17A.07.030. Buffers. <br /> 1. Purpose. Buffers shall be established and maintained to protect the functions and values of regulated <br /> wetlands. <br /> 2. Measurement.Wetland buffers shall be measured horizontally in all directions from the outer edge of <br /> wetland boundary as established in the field.Building setbacks(KCC § 17A.01.090.4)are in addition <br /> to wetland buffers and are measured outward from the edge of the wetland buffer boundary. <br /> 3. Buffer condition. Wetland buffers shall be maintained in a predominantly well-vegetated and <br /> undisturbed condition to ensure that they perform their intended function of protecting the wetland. <br /> Tree removal is prohibited in wetlands and wetland buffers other than in accordance with KCC <br /> § 17A.01.050.3.h. <br /> Downloaded from https:Hecode360.com/KI6857 on 2025-05-15 <br />
