G104.2.3 Certifications.

The permit application shall include the applicable certifications in accordance with Sections G104.2.3.1 through G104.2.3.3.

G104.2.3.1 A-Zones.

For construction in A-Zones, the permit application shall include the following certifications, as applicable:

   1.   Wet floodproofing certification. For applications involving wet floodproofed enclosures below the design flood elevation, flood zone compliance plans shall include a certification by the applicant, as applicable to the scope of work proposed, that "in accordance with ASCE 24, the use of the enclosure is limited to the parking of vehicles, building access, or storage, and that the design incorporates openings to allow for the automatic entry and exit of floodwaters for equalization of hydrostatic flood forces and flood damage-resistant materials and techniques that minimize damage to a structure by floodwater."

   2.   Dry floodproofing certification for nonresidential buildings. For applications involving dry floodproofed buildings and structures that are nonresidential (for flood zone purposes), flood zone compliance plans shall include a certification by the applicant that "the structure is designed to be dry floodproofed with walls that are substantially impermeable to the passage of water and that all walls, floors, and flood shields are designed to resist hydrostatic, hydrodynamic, and other flood-related loads, including the effects of buoyancy resulting from flooding to the elevation listed in Table 6-1 in accordance with ASCE 24."

   3.   Utility certifications. For all applications involving utility or mechanical work, including applications where such work is to be filed in a separate, related application, flood zone compliance plans shall include a certification by the applicant that "all heating, ventilation, air conditioning, plumbing, electrical and other services facilities and equipment within the structure or site will be located or constructed so as to prevent water from entering or accumulating within the components during conditions of flooding in accordance with ASCE 24."

G104.2.3.2 Coastal high-hazard areas and coastal A-Zones.

For construction in coastal high-hazard areas and coastal A-Zones, the permit application shall include the following certifications, as applicable:

   1.   Structural design certification. Flood zone compliance plans shall include a certification by the applicant that the "entire structure is designed in accordance with ASCE 24, including that the pile or column foundation and building or structure to be attached thereto is designed to be anchored to resist flotation, collapse and lateral movement due to the effects of wind and flood loads acting simultaneously on all building components, and other load requirements of Chapter 16 of the New York City Building Code."

   2.   Breakaway wall certification. Where breakaway walls are provided, flood zone compliance plans shall include a certification by applicant that "the breakaway walls meet the load requirements of Section 5.3.3 of ASCE 7, are designed in accordance with ASCE 24, and are of an open lattice-type construction only."

   3.   Utility certifications. For all applications involving utility or mechanical work, including applications where such work is to be filed in a separate, related application, flood zone compliance plans shall include a certification by the applicant that "all heating, ventilation, air conditioning, plumbing, electrical and other services, facilities and equipment within the structure or site will be located or constructed so as to prevent water from entering or accumulating within the components during conditions of flooding, in accordance with ASCE 24."

G104.2.3.3 Floodway encroachment certification.

For any floodway encroachment, including fill, new construction, substantial improvements and other development or land-disturbing activity, the applicant shall submit a certification, along with supporting technical data, demonstrating that such development will not cause any increase of the level of the base flood in accordance with the requirements of Section G103.5.

G104.3 Validity of permit.

The issuance of a permit under this appendix shall not be construed to be a permit for, or approval of, any violation of this appendix or any other provision of this code.

The commissioner is authorized to prevent occupancy or use of a structure or site that is in violation of this appendix or other provisions of this code.

G104.4 Expiration.

A permit shall become invalid if the proposed development is not commenced within 180 days after its issuance, or if the work authorized is suspended or abandoned for a period of 180 days after the work commences.
