Long Hill Township City Zoning Code
§ LU-143.14
Floodways.
[Ord. No. 90-01 § 2]
a.
Located within areas of special flood hazard established in Subsection 143.3b are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters which carry debris, potential projectiles and erosion potential, the following are prohibited in all floodways in the Township:
1.
Encroachments, including fill, new construction, substantial improvements and developments, unless certification by a professional registered engineer or architect is provided demonstrating that encroachments shall not result in any increase whatsoever in flood levels during the occurrence of the base flood discharge.
b.
If Subsection a1 is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of Subsection 143.9.
c.
In all areas of special flood hazard in which base flood elevation data has been provided and no floodway has been designated, the cumulative effect of any proposed development when combined with all other existing and anticipated development, shall not increase the water surface elevation of the base flood more than 0.2 of a foot at any point.
