A. Designation Of Administrator: The Planning and Zoning Administrator, hereinafter referred to as the "Floodplain Coordinator", is hereby appointed to administer and implement the provisions of this chapter.
B. Duties And Responsibilities Of The Floodplain Coordinator: The Floodplain Coordinator shall perform, but not be limited to, the following duties:
1. Review all floodplain development applications and issue permits for all proposed development within special flood hazard areas to assure that the requirements of this chapter have been satisfied.
2. Review all proposed development within special flood hazard areas to assure that all necessary local, State, and Federal permits have been received, including section 404 of the Federal Water Pollution Control Act Amendments of 1972, 33 USC 1334.
3. Notify adjacent communities and the Idaho Department of Water Resources State Coordinator for the National Flood Insurance Program (NFIP) prior to any alteration or relocation of a watercourse and submit evidence of such notification to the Federal Insurance Administrator (FIA). (This is the LOMC procedure.)
4. Assure that the flood-carrying capacity within the altered or relocated portion of any watercourse is maintained.
5. Prevent encroachments into floodways unless the certification and flood hazard reduction provisions of subsection 11-1-5E of this chapter are met.
6. Obtain and maintain actual elevation (in relation to mean sea level) of the lowest floor (including basement) and all attendant utilities of all new and substantially improved structures, in accordance with the provisions of subsection C3 of this section.
7. Obtain and maintain actual elevation (in relation to mean sea level) to which all new and substantially improved structures and utilities have been floodproofed, in accordance with the provisions of subsection C3 of this section.
8. Review plans to verify all public utilities reconstructed in accordance with the provisions of subsections 11-1-5A5 through A7 of this chapter.
9. When floodproofing is utilized for a particular structure, obtain and maintain certifications from a registered professional engineer or architect in accordance with the provisions of subsections C3 of this section and 11-1-5B2 of this chapter.
10. Where interpretation is needed as to the exact location of boundaries of the special flood hazard areas, or floodways (for example, where there appears to be a conflict between a mapped boundary and actual field conditions), make the necessary interpretation. The person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in this section.
11. When base flood elevation (BFE) data has not been provided in accordance with the provisions of subsection 11-1-3B of this chapter, obtain, review, and reasonably utilize any BFE data, along with floodway data available from a Federal, State, or other source, including data developed pursuant to subsection 11-1-5C2 of this chapter, in order to administer the provisions of this chapter.
12. When base flood elevation (BFE) data is provided but no floodway data has been provided in accordance with the provisions of subsection 11-1-3B of this chapter require that no new construction, substantial improvements, or other development (including fill) shall be permitted within Zones A1-30 and AE on the community's FIRM, unless it is demonstrated that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than one foot (1') at any point within the community. (This is a Hydraulic and Hydrology Analysis.)
13. When the lowest floor and the lowest adjacent grade of a structure or the lowest ground elevation of a parcel in a special flood hazard area (SFHA) is above the base flood elevation (BFE), advise the property owner of the option to apply for a Letter of Map Amendment (LOMA) from FEMA. Maintain a copy of the LOMA issued by FEMA in the floodplain development permit file.
14. Permanently maintain all records that pertain to the administration of this chapter and make these records available for public inspection, recognizing that such information may be subject to the Privacy Act of 1974, as amended.
15. Make on-site inspections of work in progress. As the work pursuant to a floodplain development permit progresses, the Floodplain Coordinator shall make as many inspections of the work as may be necessary to ensure that the work is being done according to the provisions of the local ordinance and the terms of the permit. In exercising this power, the Floodplain Coordinator has a right, upon presentation of proper credentials, to enter on any premises within the jurisdiction of the community at any reasonable hour for the purposes of inspection or other enforcement action.
16. Issue stop-work orders as required. Whenever a building or part thereof is being constructed, reconstructed, altered, or repaired in violation of this chapter, the Floodplain Coordinator may order the work to be immediately stopped. The stop-work order shall be in writing and directed to the person doing or in charge of the work. The stop-work order shall state the specific work to be stopped, the specific reason(s) for the stoppage, and the condition(s) under which the work may be resumed. Violation of a stop-work order constitutes a misdemeanor.
17. Revoke floodplain development permits as required. The Floodplain Coordinator may revoke and require the return of the floodplain development permit by notifying the permit holder in writing stating the reason(s) for the revocation. Permits shall be revoked for any substantial departure from the approved application, plans, and specifications; for refusal or failure to comply with the requirements of State or local laws; or for false statements or misrepresentations made in securing the permit. Any floodplain development permit mistakenly issued in violation of an applicable State or local law may also be revoked.
18. Make periodic inspections throughout the special flood hazard areas within the jurisdiction of the community. The Floodplain Coordinator and each member of his or her Inspections Department shall have a right, upon presentation of proper credentials, to enter on any premises within the territorial jurisdiction of the department at any reasonable hour for the purposes of inspection or other enforcement action.
19. Follow through with corrective procedures of subsection D of this section.
20. Review, provide input, and make recommendations for variance requests.
21. Maintain a current map repository to include, but not limited to, the FIS Report, FIRM and other official flood maps, and studies adopted in accordance with the provisions of subsection 11-1-3B of this chapter, including any revisions thereto including Letters of Map Change, issued by FEMA. Notify the NFIP State Coordinator and FEMA of the community's mapping needs.
22. Coordinate revisions to FIS reports and FIRMs, including Letters of Map Revision Based On Fill (LOMR-Fs) and Letters of Map Revision (LOMRs).
23. A community's base flood elevations may increase or decrease resulting from physical changes affecting flooding conditions. As soon as practicable, but not later than six (6) months after the date such information becomes available, a community shall notify the Federal Insurance Administrator (FIA) of the changes by submitting technical or scientific data in accordance with this chapter. Such a submission is necessary so that upon confirmation of those physical changes affecting flooding conditions, risk premium rates and floodplain management requirements will be based upon current data.
24. Upon occurrence, notify the Federal Insurance Administrator (FIA) in writing whenever the boundaries of the community have been modified by annexation or the community has otherwise assumed or no longer has authority to adopt and enforce floodplain management regulations for a particular area. In order that all FHBMs and FIRMs accurately represent the community's boundaries, include within such notification a copy of a map of the community suitable for reproduction, clearly delineating the new corporate limits or new area for which the community has assumed or relinquished floodplain management regulatory authority.
25. Determine if Valley County should hire a licensed engineer to review any information provided. If a licensed engineer is required it shall be at the expense of the applicant.

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, a Floodproofing Certificate (FEMA Form 086-0-34), with supporting data, an operational 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 Coordinator 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 Coordinator 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. Failure to construct in accordance with the certified design shall be cause to withhold the issuance of a Certificate of Compliance/Occupancy.
c. Manufactured Home: If a manufactured home is placed within Zone A, AE, AH, AO, or A1-30 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 11-1-5B3b of this chapter.
