r'1% <br /> APPENDIX D <br /> ~ Establishing and Certifying Credits <br /> - Mitigation Credits <br /> Within the mitigation ,bank system, mitigation credits aze the unit of measurement for' <br /> describing wetland impact compensation requirements (demand) and for how these requirements are <br /> satisfied (supply). For each acre of wetland impact, one mitigation credit is required and can' be <br /> purchased from the Mitigation Bank Program (the "Program") to satisfy the impact requirement. <br /> Credit Supply <br /> - Mitigation credits are. established by the Program through restoration, creation, enhancement, <br /> and preservation activities.' because these activities have vazying levels ~of risk and capacity for <br /> wetland gains, ratios have been established to reflect these varying conditions. The ratios express <br /> the compensation values for each wetland impact acre (e.g.,1.0:1 means 1 acre of mitigation for each ` <br /> acre of impact): Restoration is the preferred mitigation activity-and results in more mitigation credits <br /> than creation and enhancement.. activities. The following ratios apply to bank conditions and, - <br /> therefore, assumes mitigation activities ;occur prior to wetland impacts. These ratios aze then <br /> converted to the bank credit factor by dividing one .(1) by the. ratio (for example 1.5/1= .66 credits). <br /> <br /> z" <br /> Mitigation Method Ratios Ban redit actor <br /> Restoration - 1.0:1 1.0 <br /> .Creation 1.5:1 0.66 <br /> . Enhancement 2.5:1 ~ 0.40 <br /> To determine the potential,mitigation credits of a given mitigation bank site, multiply the~_ <br /> applicable, mitigation credit factor (1.0; 0.66; 0.4.0) by the number of restoration, creation and <br /> .enhancement acres of the mitigation site. The sum of these products equals the potential mitigation <br /> . credits of the bank site. For example, assume a mitigation bank site to be 6 acres in size with each <br /> of the mitigation methods possible on 2 acres.. The following mitigation credits could be realized. <br /> iti afro eth d ize acres iti atio Credi actor ~ iti atio Credits <br /> - Restoration - 2.0 x 1.0 = 2.00 <br /> Creation 2.0 x 0.66 = 1.32 - <br /> -Enhancement ~ 2.0 x 0.40 = 0.80 <br /> Total: ~ 6.0 4.12 <br /> ti <br /> Credits for preservation shall be determined on an individual, case-by-case basis. <br /> Page 1= Appendiz D <br /> MOA For West Eugene Wetlands Mitigation Banking Program _ <br /> <br />
