Kittitas County, WA <br />§ 17A.07.070 CRITICAL AREAS § 17A.07.070 <br />Downloaded from https://ecode360.com/KI6857 on 2025-05-15 <br /> <br /> <br /> <br />which preclude implementation of the mitigation plan. The justification must be verified and <br />approved by the County and include a financial guarantee. <br />5. Preference of mitigation actions. Compensatory wetland mitigation shall occur in the following order <br />of preference: <br />a. Purchasing credits from an approved Mitigation Bank if available and feasible, Purchasing <br />credits from an approved In-Lieu Fee program if available and feasible, and Permittee <br />Responsible Mitigation (PRM). <br />b. In order of preference, the following PRM methods are available: (1) Restoration [re- <br />establishment or rehabilitation], (2) Establishment [creation], (3) Preservation of existing high <br />quality habitats, and (4) Enhancement of degraded wetlands. <br />6. Replacement ratios for wetland impacts. Ratios for compensatory mitigation shall be as specified in <br />Table KCC 17.07.070.6. The first number specifies the acreage of replacement wetlands, and the <br />second specifies the acreage of wetlands altered. Compensatory mitigation shall restore, rehabilitate, <br />create, or enhance equivalent or greater wetland functions. The ratios shall apply to mitigation that is <br />in-kind, is on-site, is the same category, is timed prior to or concurrent with alteration, and has a high <br />probability of success. The Director may increase these ratios for remedial mitigation actions resulting <br />from unauthorized wetland alterations, depending on the nature and extent of the alteration. These <br />ratios do not apply to the use of credits from a certified wetland mitigation bank or in-lieu fee program. <br />When credits from a certified bank or in-lieu fee program are used, replacement ratios should be <br />consistent with the requirements of the bank's/program's certification. <br /> <br />Table 17A.07.070.6: Wetland Mitigation Ratios <br />Category and Type of <br />Impacted Wetland <br />Restoration or <br />Creation1,2 <br /> <br />Rehabilitation2,2 <br /> <br />Enhancement Only1,3 <br />Category I, forested 6:1 12:1 24:1 <br />Category I, non- <br />forested <br />4:1 8:1 16:1 <br />Category II, forested 4:1 8:1 16:1 <br />Category II, vernal <br />pool4 <br />2:1 4:1 Case-by-case <br />All other Category II 3:1 6:1 12:1 <br />All Category III 2:1 4:1 8:1 <br />All 1.5:1 3:1 6:1 <br />Category IV
