requirements and total environmental impacts including <br />impacts to rare species and their habitat, and to wetlands <br />designated in the Plan for restoration or protection. <br />b. The new construction cannot reasonably be constructed <br />completely outside of wetlands designated for protection as <br />demonstrated in the above - referenced alternatives analysis; <br />C. The utility lines are located so as to reduce the impact to <br />wetlands designated for protection as much as possible, and in <br />no case shall a cumulative area greater than 1 acre be re- <br />designated from "protection" to "utility corridor" for a new <br />utility line; <br />d. Unavoidable impacts will be mitigated through restoration of <br />the project's entire impact area; <br />e. There are no impacts to wetlands from new utility lines <br />installed within the willow Creek Natural Area; and <br />f. Impacts to rare plant and animal species will not occur. <br />(g) Other than the activities described in this policy, these corridors shall be <br />treated as protected wetlands. Allowed activities shall be conducted in <br />such a manner as to minimiz adverse impacts to the maximum extent <br />possible upon the wetlands within the corridor itself and within <br />surrounding protected wetlands. wetland impacts shall be limited to the <br />minim area necessary. Utility agencies shall use the best feasible <br />technology to pinpoint the location of needed repairs prior to excavation in <br />order to limit the area of impact. <br />(h) Except for emergency repairs, these activities shall be planned and timed <br />to minimi adverse impacts to wetlands. <br />(i) All impacts shall be followed by restoration activities including: <br />1. Backfilling with existing native soil within three feet of the surface <br />whenever possible, and in no case less than two feet; and <br />2. grading and re- seedling and/or replanting with appropriate native <br />plant species. <br />(j) Any unavoidable impacts to rare plant species shall be mitigated through <br />coordinated transplanting or other measures. (Policy 3.21) <br />(13) The plant and animal species listed below shall be considered rare for the <br />purposes and policies of this Plan: <br />Rare Plants: <br />white - topped aster Aster curtus <br />Willamette daisy Erigeron decumbens var. decumbens <br />Shaggy horkelia Horkelia congests. <br />Bradshaw's lomatium Lomatium bradshawii <br />Timwort Cicendia quadrangularis <br />[]rdinance - 416 <br />
