(8) Documentation for placement of recreational vehicles and/or temporary structures, when applicable, to ensure § 154.46(F) and (G) of this chapter are met; and
(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 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 description of the development to be permitted under the floodplain development permit;
(2) The special flood hazard area determination for the proposed development per available data specified in § 154.07;
(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
(7) The flood openings requirements, if in Zones A, AO, AE, or A1-30.
(C) Certification requirements.
(1) Elevation certificates.
(a) An elevation certificate (FEMA Form 81-31) 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 mean sea level. 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) An elevation certificate (FEMA Form 81-31) is required after the reference level is established. Within seven calendar days of establishment of the reference level elevation, 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 mean sea level. Any work done within the seven-day calendar period and prior to submission of the certification shall be at the permit holder’s risk. 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 further work being permitted to proceed. Failure to submit the certification or failure to make required corrections shall be cause to issue a stop-work order for the project.
(c) 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 date 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. If non-residential floodproofing is used to meet the regulatory flood protection elevation requirements, a floodproofing certificate (FEMA Form 81-65), with supporting data and an operational plan, 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 floodproofed design elevation of the reference level and all attendant utilities, in relation to mean sea level. Floodproofing certification 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 and plan. Deficiencies detected by such review shall be corrected by the applicant prior to permit approval. 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 withhold the issuance of a certificate of compliance/occupancy.
(3) Manufactured homes. If a manufactured home is placed within Zone A, AO, AE, or A1-30 and the elevation of the chassis is 36 inches in height above grade, an engineered foundation certification is required per § 154.46(C).
(4) Watercourse. 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 divisions (C)(1) and (C)(2) above:
(a) Recreational vehicles meeting requirement of § 154.46(F)(1);
(b) Temporary structures meeting requirements of § 154.46(G); and
(c) Accessory structures less than 150 square feet meeting requirement of § 154.46(H).
(6) V-zone certification. A v-zone certification with accompanying design plans and specifications is required prior to issuance of a floodplain development permit within coastal high hazard areas. It shall be the duty of the permit applicant to submit to the Floodplain Administrator said certification to ensure the design standards of this chapter are met. A registered professional engineer or architect shall develop or review the structural design, plans, and specifications for construction and certify that the design and methods of construction to be used are in accordance with accepted standards of practice for meeting the provisions or this chapter. This certification is not a substitute for an elevation certificate.
