Wetland <br />impacts will be evaluated based on the following principles in descending order of priority. Avoid the <br />impact to the wetland, minimize the impact to the wetland, replace the wetland that was impacted, Wetland <br />impacts will be governed by a Rule comparable to the Wetland Conservation Act, with the following <br />exceptions: <br />1. The de minimis size will be zero. <br />2. Flexibility Sequencing will not be allowed. <br />3. Public Value Credits can not be used for replacement. <br /> <br />A 25-foot buffer of permanent nonimpacted vegetative ground cover abutting and surrounding a wetland is <br />required. <br /> <br />Rule Threshold <br />This rule will apply to all wetlands in CRWD. <br /> <br />Technical Criteria for Rules - June 29, 2005 <br /> <br />2 <br />
