2) conduct essential maintenance (e.g., work to maintain or optimize performance) on existing utility lines, including line locating, 3) construct connections to existing utility lines, 4) construct new utility lines, 5) move existing utility lines when necessary to maintain service or conduct emergency repairs, and when at least one of the following is true: a) the utility line must be moved to protect it from erosion or some other natural threat; b) construction of public facilities that are consistent with this plan and that conflict with an existing utility line, where such public facilities cannot reasonably be constructed without moving the utility line; or c) the utility line must be moved in order to maintain or repair another utility line in the same vicinity. 6) place new utility poles or replace existing utility poles, only when necessary to maintain performance or safety of above-ground utility lines. Above-ground utility lines may not be replaced with underground utility lines within wetlands designated for restoration or protection. No other impacts are authorized by this policy. The following shall also apply to these corridors: a. The corridors for underground utility lines shall be 20 feet wide for excavations or pipes up to 10 feet below ground surface (bgs), 30 feet wide for excavations or pipes from 10 to 15 feet bgs, and 40 feet wide for excavations or pipes deeper than 15 feet bgs. Where two utility lines are close to each other, the corridors for the lines may overlap, but impacts for work on one line are allowed only within the corridor width for that line, not the combined width of both lines. b. The corridors for above ground utility lines shall be 10 feet wide for single pole structures and 20 feet wide for double pole ("H-style") structures. c. The utility corridors shall be centered on an existing utility line, extending an equal distance (half the allowed width) on both sides, except for corridors for new utility lines, which shall be located as specified in subsection d below. d. Construction of new utility lines and new connections to existing utility lines within wetlands designated for protection shall require an amendment of this plan to change the designation from "protect" to "utility line corridor." Such amendments will only be allowed where it is demonstrated that: 1) an alternatives analysis has concluded that locating . the new utility line within a protected wetland is the best alternative. The alternatives analysis shall compare alternatives that are completely outside of protected wetlands and compare them to any alternatives that impact protected wetlands. The alternatives shall be evaluated by weighing engineering requirements and total environmental impacts including impacts to rare species and their habitat, and to wetlands designated in the Plan fororestoration or protection. 2) the new construction cannot reasonably be constructed completely outside Multiple Site Ordinance, Exhibit C (Refinement Plan Amendment Findings) Page 32
