§ 4.6.4. Permits.

A.

No person shall erect or alter any structure within the airport zones without first applying for and receiving a permit in accordance with the provisions of this Ordinance.

B.

Before any existing structure may be replaced, substantially altered or repaired, or rebuilt within the airport zones, a permit must be secured authorizing such replacement, change or repair. No such permit shall be granted that would allow the establishment or creation of an airport hazard or permit a nonconforming structure to be made or become higher than the height limit as determined by the aerial contours appearing on the Height Zoning Map or referred to in Section 4.6.1.

C.

When compliance with the aerial contour height limits cannot be clearly established without further information, the zoning administrator may require that the permit include, but not be limited to, the ground elevation of the area in question with certification by a registered land surveyor or professional engineer.
