Section 19:4-9.27 - Floodways

(a) Areas designated as floodways are located within certain areas of special flood hazard. Since the floodway is an extremely hazardous area due to the velocity of flood waters that carry debris, potential projectiles, and erosion potential, the following provisions apply:

1. Encroachments in floodways, including new fill, new construction, substantial improvements, and other development, are prohibited, unless a technical evaluation demonstrates that encroachment shall not result in any increase in flood levels during the occurrence of the base flood discharge.

2. If (a)1 above is satisfied, all new construction and substantial improvements shall comply with this subchapter.

3. In all areas of special flood hazard in which base flood elevation data has been provided and a 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 two-tenths of a foot at any point.
