Protected trees
Permit needed for trees at least 4 inches DBH on all non-residential lots, residential lots larger than 1 acre, land within a conservation resource setback or protective buffer, and any property in a local historic district (any lot size). Historic district removals also need a Certificate of Appropriateness. Protected trees may be removed only if essential site parts cannot fit elsewhere on the site (Land Development Code Sec. 18-316(C)). Removing a specimen tree needs Board of Adjustment approval in all zoning districts except IND.
