Be constructed of flood-damage-resistant materials; and
E. 
Have mechanical, plumbing, and electrical systems above the base flood elevation or meet the requirements of ASCE 24, except that minimum electric service required to address Life Safety and Electrical Code requirements is permitted below the base flood elevation, provided it conforms to the provisions of the electrical part of Building Code for wet locations.
Fences in floodways that have the potential to block the passage of floodwater, such as stockade fences and wire mesh fences, shall meet the requirements of § 135-9.1D of these regulations.
