A. Designation Of Floodplain Administrator: The City Engineer, or designee, hereinafter referred to as the "Floodplain Administrator," is hereby appointed to administer and implement the provisions of this chapter.
B. Duties And Responsibilities Of The Floodplain Administrator: The Floodplain Administrator 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. This is a hydraulic and hydrology analysis.
5. Prevent encroachments into floodways unless the certification and flood hazard reduction provisions of section 15.32.150 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 section 15.32.080C.
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 section 15.32.080C.
10. Where interpretation is needed as to the exact location of boundaries of the special flood hazard areas, and 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 section 15.32.060B, 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 section 15.32.130B, 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 section 15.32.060B, require that no new construction, substantial improvements, or other development (including fill) shall be permitted within Zone 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. 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.
14. Make on-site inspections of work in progress. As the work pursuant to a floodplain development permit progresses, the Floodplain Administrator 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 Administrator 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.
15. 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 Administrator 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.
16. Revoke floodplain development permits as required. The Floodplain Administrator 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.
17. Make periodic inspections throughout the special flood hazard areas within the jurisdiction of the community. The Floodplain Administrator 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.
18. Follow through with corrective procedures of section 15.32.090.
19. Review, provide input, and make recommendations for variance requests.
20. 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 15.32.060B of this chapter, including any revisions thereto including letters of map change, issued by FEMA. Notify the NFIP State Coordinator and FEMA of your community's mapping needs.
21. Coordinate revisions to FIS reports and FIRMs, including letters of map revision based on fill (LOMR-Fs) and letters of map revision (LOMRs).
22. 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 part. 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.
23. 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 FHBM's and FIRM's 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.
