The provisions of this Section are subject to all provisions of Title 28 of the Administrative Code of the City of New York and Appendix G of the New York City Building Code, or its successors, including those pertaining to expiration, reinstatement, revocation and suspension. Changes in flood maps shall be considered an amendment of the Zoning Resolution for the purposes of applying the provisions of Section 11-30 (BUILDING PERMITS ISSUED BEFORE EFFECTIVE DATE OF AMENDMENT).

(a)        Construction approved pursuant to previous versions of flood maps

If, within one year prior to a change in the flood maps affecting a property, the Department of Buildings issued a building permit for construction on that property pursuant to the previous flood maps, the provisions of Article VI, Chapter 4 (Special Regulations Applying in Flood Hazard Areas) shall be deemed modified so as to substitute the previous flood maps for the current flood maps and such construction may continue pursuant to such prior flood maps until two years after the date of adoption of the new flood maps. After this date, the vesting provisions of Section 11-30 shall apply.

(b)        Provisions applying when Appendix A (Special Regulations for Neighborhood Recovery) of Article VI, Chapter 4 expires

This provision shall become effective only upon the expiration of Appendix A of Article VI, Chapter 4, adopted on July 23, 2015. If a building permit authorizing construction pursuant to Appendix A has been approved on or before the expiration of such Appendix, construction may continue up to two years after the expiration. After such date, the provisions of Section 11-30 shall apply.
