1. City of Gloucester Wind Turbine Siting

2. Background Prior to May 17, 2007 – Wind Energy Conversion Devices – Special Permitted in any district by ZBA – Footnote Standard: WECD shall be set back from every property line by a distance equal to its height (to tip of blade) except where a “fall area” easement is obtain, enclosed by 6’ fencing and anti-climbing devices as approved by Building Inspector
