(A) Discrepancies between boundaries on the official floodplain zoning map and actual field conditions shall be resolved using the criteria in divisions (A)(1) or (A)(2) below. If a significant difference exists, the map shall be amended according to § 152.18 of this subchapter. The Zoning Administrator can rely on a boundary derived from a profile elevation to grant or deny a land use permit, whether or not a map amendment is required. The Zoning Administrator shall be responsible for documenting actual pre-development field conditions and the basis upon which the district boundary was determined and for initiating any map amendments required under this section. Disputes between the Zoning Administrator and an applicant over the district boundary line shall be settled according to § 152.48(C) of this chapter and the criteria in divisions (A)(1) or (A)(2) below.
(1) If flood profiles exist, the map scale and the profile elevations shall determine the district boundary. The regional or base flood elevations shall govern if there are any discrepancies.
(2) Where flood profiles do not exist, the location of the boundary shall be determined by the map scale, visual on-site inspection and any information provided by the Department.
(B) Where the flood profiles are based on established base flood elevations from a FIRM, FEMA must also approve any map amendment pursuant to § 152.18(A)(6) of this chapter.
