Section 7:13-3.1 - General provisions for determining the flood hazard area and floodway along a regulated water

(a) This subchapter provides six methods for determining the flood hazard area and floodway along a regulated water as follows:

1. Method 1 (Department delineation method) as described at 7:13-3.3;

2. Method 2 (FEMA tidal method) as described at 7:13-3.4(d);

3. Method 3 (FEMA fluvial method) as described at 7:13-3.4(e);

4. Method 4 (FEMA hydraulic method) as described at 7:13-3.4(f);

5. Method 5 (approximation method) as described at 7:13-3.5; and

6. Method 6 (calculation method) as described at 7:13-3.6.

(b) The flood hazard area is the land, and the space above that land, which lies below the flood hazard area design flood elevation, as defined at 7:13-1.2. The six methods described in (a) above provide the flood hazard area design flood elevation, from which the flood hazard area limit on a site is determined. In some cases, the limits of the floodway can also be determined using these methods.

(c) The flood hazard area and floodway described in this subchapter may differ from areas identified as a "flood hazard area," "flood zone," "floodplain" or "floodway" by another public entity such as FEMA or a local government. The methods listed at (a) above are specifically designed and intended for determining compliance with the construction standards and requirements of this chapter.
