I. 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.
(2) Permit Requirements: The floodplain development permit shall include, but not be limited to:
A. A complete description of all the development to be permitted under the floodplain development permit (i.e., house, garage, pool, septic, bulkhead, cabana, pole barn, chicken coop, pier, bridge, mining, dredging, filling, rip-rap, docks, grading, paving excavation or drilling operations, or storage of equipment or materials, etcetera).
B. The special flood hazard area determination for the proposed development in accordance with available data specified in subsection 07-10A-05(2) of this article.
C. The flood protection elevation required for the lowest floor and all attendant utilities.
D. The flood protection elevation required for the protection of all utility equipment and machinery.
E. All certification submittal requirements with timelines.
F. A statement that no fill material or other development shall encroach into the floodway of any watercourse, as applicable.
G. The flood openings requirements.
H. All floodplain development permits shall be conditional upon the start of construction of work within one hundred eighty (180) days after issuance unless the permitted activity has commenced as per the start of construction definition.
I. Fully enclosed areas below the lowest floor are usable solely for parking of vehicles, building access or storage.
J. All materials below BFE/FPE must be flood resistant materials.
(3) Certification Requirements:
A. Elevation Certificates:
1. A Construction Drawings Elevation Certificate (form provided by FEMA) 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 lowest floor, 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.
2. A Final As Built Finished Construction Elevation Certificate (form provided by FEMA) 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 lowest floor 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. The Finished Construction Elevation Certificate certifier shall provide at least two (2) photographs showing the front and rear of the building taken within ninety (90) days from the data certification. The photographs must be taken with views confirming the building description and diagram number provided in section A of the certificate. To the extent possible, these photographs should show the entire building including foundation. If the building has split-level or multi- level areas, provide at least two (2) additional photographs showing side views of the building. In addition, when applicable, provide a photograph of the foundation showing a representative example of the flood openings or vents. All photographs must be in color and measure at least 3" x 3". Digital photographs are acceptable.
B. Floodproofing Certificate: If non-residential floodproofing is used to meet the flood protection elevation requirements, design plans, with supporting data, an operation plan and an inspection and maintenance plan are 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 lowest floor 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, the operational plan, and the inspection and maintenance 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. Prior to request for a Certificate of Compliance/Occupancy a Floodproofing Certificate (FEMA 086-0-34) shall be provided to the Floodplain Administrator for review and approval.
C. Manufactured Home: If a manufactured home is placed within Zone A, AE, AH, and AO, and the elevation of the chassis is more than thirty six inches (36") in height above grade, an engineered foundation certification is required in accordance with the provisions of subsection 07-10A-11(2)D2 of this article.
D. Alter Or Relocate Watercourse: If a watercourse is to be altered or relocated, the following shall all be submitted by the permit applicant prior to issuance of a floodplain development permit:
1. A description of the extent of watercourse alteration or relocation; and
2. 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
3. A map showing the location of the proposed watercourse alteration or relocation; and
4. An Idaho stream channel alteration permit approval shall be provided by the applicant to the Floodplain Administrator.
E. Certification Exemptions: The following structures are exempt from the elevation/floodproofing certification requirements specified in subsections (3)A and (3)B of this section:
1. Recreational vehicles meeting requirements of subsection 07-10A-11(2)E of this article;
2. Temporary structures meeting requirements of subsection 07-10A-11(2)F of this article; and
3. Accessory structures one thousand five hundred (1,500) square feet or less meeting requirements of subsection 07-10A-11(2)G of this article. (Ord. 19-038, 8-30-2019)
