G102.2.1 Preliminary flood insurance study and rate maps.

Until such time that the department by rule adopts revised FEMA FIS 360497 and FEMA FIRMs 360497 with a final effective date later than May 1, 2014, the following flood hazard maps and supporting data are also adopted as a referenced standard and declared a part of this appendix.

   1.   FEMA PFIS 360497.

   2.   FEMA PFIRMs 360497.

G102.2.2 Effect of preliminary flood insurance study and rate maps.

Notwithstanding any other provision in this appendix to the contrary:

   1.   All references in this appendix to elevations in FEMA FIS 360497 and FEMA FIRMs 360497 shall be deemed to refer to the greater of (i) the elevations identified in the FEMA FIS 360497/FEMA FIRMs 360497 or (ii) the elevations identified in the FEMA PFIS 360497/FEMA PFIRMs 360497. In comparing elevations, the elevations identified in FEMA FIS 360497 and FEMA FIRMs 360497 that are expressed in relation to the National Geodetic Vertical Datum (NGVD) shall be converted to the North American Vertical Datum (NAVD).

   2.   All references in this appendix to flood hazard areas as delineated on FEMA FIRMs 360497 shall be deemed to refer to the flood hazard areas as delineated on FEMA PFIRMs 360497 except that, where a structure is located in a flood hazard area as delineated on FEMA PFIRMs 360497 and in a more restrictive flood hazard area as delineated on FEMA FIRMs 360497, such structure shall be deemed to be located in the more restrictive flood hazard area as delineated on FEMA FIRMs 360497.

G102.3 Letters of map change.

Map changes to FEMA FIRMs 360497 shall be administered in compliance with Sections G102.3.1 through G102.3.3.

G102.3.1 Letters of map amendment (LOMA).

Where FEMA FIRMs 360497 indicates that a structure or tax lot is within a delineated special flood hazard area, but the pre-FIRM ground elevations adjacent to the structure or throughout the tax lot are at or above the base flood elevation, the commissioner shall deem such structure or tax lot as being within the special flood hazard area and shall not approve plans except in compliance with this appendix, unless a letter of map amendment (LOMA) is issued by FEMA removing such structure or tax lot from the special flood hazard area.

G102.3.1.1 Letters of map amendment (LOMAs) during pendency of PFIRMs.

Until such time that the department by rule adopts revised FEMA FIS 360497 and FEMA FIRMs 360497 with a final effective date later than April 18, 2018, the commissioner shall not deem issuance of a LOMA by FEMA as removing such structure or tax lot from the special flood hazard area unless the elevations specified in the LOMA equal or exceed the applicable corresponding elevations on the FEMA PFIS 360497/FEMA PFIRMs 360497.

G102.3.2 Letter of map revision based on fill (LOMR-F).

Where FEMA FIRMs 360497 indicates that a structure or tax lot is within a delineated special flood hazard area, but post-FIRM compacted fill is proposed to be added adjacent to the structure or throughout the tax lot to an elevation at or above the base flood elevation, the commissioner shall deem such structure or tax lot as being within the special flood hazard area and shall not approve plans except in compliance with this appendix, unless a conditional or final letter of map revision based on fill (LOMR-F) is issued by FEMA removing such structure or tax lot from the special flood hazard area. Buildings constructed with basements below the Base Flood Elevation on filled land shall maintain a minimum setback distance of 20 feet (6096 mm), at or above the Base Flood Elevation, from the edge of the special flood hazard area to the nearest wall of the basement, regardless of the design approach used. The commissioner shall promulgate rules establishing procedures for processing letters of map revision based on fill (LOMR-F).

G102.3.2.1 Letters of map revision based on fill (LOMR-Fs) during pendency of PFIRMs.

Until such time that the department by rule adopts revised FEMA FIS 360497 and FEMA FIRMs 360497 with a final effective date later than April 18, 2018, the commissioner shall not deem issuance of a LOMR-F as removing such structure or tax lot from the special flood hazard area unless the elevations specified in the LOMR-F equal or exceed the applicable corresponding elevations on the FEMA PFIS 360497/FEMA PFIRMs 360497.

G102.3.3 Certificates of occupancy.

Certificates of occupancy shall indicate that the structure or tax lot is subject to a letter of map amendment (LOMA) or letter of map revision based on fill (LOMR-F) as per Section G106.5.
