(g) The certification of the plot plan by a registered land surveyor or professional engineer (this is a normal requirement for subdivision of property in Vance County), however when the site/property is located in a floodplain then a floodplain certification block is required to be included on the plot plan (as illustrated below, for use when lots are located in a special flood hazard area):
Floodplain Determination:
Lot (s) __________ is (are) located in a federally identified Special Flood Hazard Area as depicted on this plat. Individual site plan approval is required for any lot located within or partially within a special flood hazard area prior to the issuance of any permits.

(a) The proposed method of elevation, if applicable (i.e., fill, solid foundation perimeter wall, solid backfilled foundation, open foundation on columns/posts/piers/piles/shear walls);
(b) Openings to facilitate automatic equalization of hydrostatic flood forces on walls in accordance with § 153.36(D)(3) when solid foundation perimeter walls are used in Zones A, AO, AE, and A1-30;
(5) Usage details of any enclosed areas below the lowest floor.
(6) Plans and/or details for the protection of public utilities and facilities such as sewer, gas, electrical, and water systems to be located and constructed to minimize flood damage;
(7) Copies of all other local, state and federal permits required prior to floodplain development permit issuance (wetlands, endangered species, erosion and sedimentation control, CAMA, riparian buffers, mining, etc.)
(8) Documentation for placement of recreational vehicles and/or temporary structures, when applicable, to ensure that the provisions of § 153.36(F) and (G) are met.
(9) A description of proposed watercourse alteration or relocation, when applicable, including an engineering report on the effects of the proposed project on the flood-carrying capacity of the watercourse and the effects to properties located both upstream and downstream; and a map (if not shown on plot plan) showing the location of the proposed watercourse alteration or relocation.
(B) Permit requirements. The floodplain development permit shall include, but not be limited to:
(1) A complete description of all the development to be permitted under the floodplain development permit (e.g. house, garage, pool, septic, bulkhead, cabana, pier, bridge, mining, dredging, filling, grading, paving, excavation or drilling operations, or storage of equipment or materials, etc.).
(2) The special flood hazard area determination for the proposed development in accordance with the available data specified in § 153.07.
(3) The regulatory flood protection elevation required for the reference level and all attendant utilities.
(4) The regulatory flood protection elevation required for the protection of all public utilities.
(5) All certification submittal requirements with timelines.
(6) A statement that no fill material or other development shall encroach into the floodway or non-encroachment area of any watercourse unless the requirements of § 153.40 have been met.
(7) The flood openings requirements, if in Zones A, AO, AE or A1-30.
(8) Limitations of use, i.e., parking, building access and limited storage only, of the enclosures below the lowest floor (if applicable.
(C) Certification requirements.
(1) Elevation certificates.
(a) An elevation certificate (FEMA Form 086-0-33) is required prior to the actual start of any new construction. It shall be the duty of the permit holder to submit to the Floodplain Administrator a certification of the elevation of the reference level, in relation to NAVD 1988. The Floodplain Administrator shall review the certificate data submitted. Deficiencies detected by such review shall be corrected by the permit holder prior to the beginning of construction. Failure to submit the certification or failure to make required corrections shall be cause to deny a floodplain development permit.
(b) A final as-built elevation certificate (FEMA Form 81-31) is required after construction is completed and prior to certificate of compliance/occupancy issuance. It shall be the duty of the permit holder to submit to the Floodplain Administrator a certification of final as-built construction of the elevation of the reference level and all attendant utilities. The Floodplain Administrator shall review the certificate data submitted. Deficiencies detected by such review shall be corrected by the permit holder immediately and prior to certificate of compliance/occupancy issuance. In some instances, another certification may be required to certify corrected as-built construction. Failure to submit the certification or failure to make required corrections shall be cause to withhold the issuance of a certificate of compliance/occupancy.
(2) Floodproofing certificate. A final finished construction floodproofing certficate (FEMA Form 81-65), with supporting data, an operational plan, and an inspection and maintenance plan are required prior to the issuance of a certificate of compliance/occupancy. It shall be the duty of the permit holder to submit to the Floodplain Administrator a certification of the floodproofed design elevation of the reference level and all attendant utilities, in relation to NAVD 1988. Floodproofing certificate shall be prepared by or under the direct supervision of a professional engineer or architect and certified by same. The Floodplain Administrator shall review the certificate data, the operational plan, and the inspection and maintenance plan. Deficiencies detected by such review shall be corrected by the applicant prior to certificate of occupancy. Failure to submit the certification or failure to make required corrections shall be cause to deny a floodplain development permit. Failure to construct in accordance with the certified design shall be cause to deny a certificate of compliance/occupancy.
(3) If a manufactured home is placed within Zone A, AO, AE, or A1-30 and the elevation of the chassis is more than 36 inches in height above grade, an engineered foundation certification is required in accordance with the provisions of § 153.36(C)(2).
(4) If a watercourse is to be altered or relocated, a description of the extent of watercourse alteration or relocation; a professional engineer's certified report on the effects of the proposed project on the flood-carrying capacity of the watercourse and the effects to properties located both upstream and downstream; and a map showing the location of the proposed watercourse alteration or relocation shall all be submitted by the permit applicant prior to issuance of a floodplain development permit.
(5) Certification exemptions. The following structures, if located within Zone A, AO, AE or A1-30, are exempt from the elevation/floodproofing certification requirements specified in items (a) and (b) of this subsection:
