   1.   Duties Of The Floodplain Administrator (Boise Planning Director): The Boise City Planning Director is hereby appointed to administer and implement this chapter and, as the Floodplain Administrator, shall perform the following duties:

      A.   Review Applications: Review all applications for Base Zone District changes, subdivisions, special use permits, conditional use permits and planned developments to determine:

         (1)   If the development is within an area of special flood hazard;

         (2)   To determine that all necessary permits have been obtained from those federal, state, or local governmental agencies from which prior approval is required; and

         (3)   For compliance with the provisions of this chapter and disclose to the PZC and Council whether the application is, or is not, in compliance with the provisions of this chapter.

      B.   Interpretations:

         (1)   Make interpretations of the location of the boundaries of the Floodway and the Floodway Fringe.

         (2)   When uncertainty exists as to whether a new development is within an Area of Special Flood Hazard, determine whether development is within the Floodway or Floodway Fringe.

      C.   Zoning Certificates: Issues zoning certificates for those structures which are to be constructed or modified in compliance with the provisions of this chapter and the other applicable provisions of this code.

      D.   Variances: Variances may be issued by the Director for the reconstruction, rehabilitation or restoration of "historic structures" upon a determination that the proposed repair or rehabilitation will not preclude the structure's continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure.

      E.   Available Data: Obtain, review, and reasonably utilize any base flood elevation and floodway data available from a federal, state or other source when such data has not been provided in the Flood Insurance Study.

      F.   Record Keeping: Compile and maintain in perpetuity for public inspection all records pertaining to the provisions of this chapter, including records of all appeal actions and variances, records of first floor elevations, flood-proofing certificates, letters of map amendment and all other records required by this chapter and by federal regulations.

      G.   Notification: Notify adjacent jurisdictions and the Idaho Department of Water Resources prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Insurance Administrator; and require that the flood-carrying capacity of the altered or relocated portion of said watercourse is maintained.

         (1)   Base Flood Elevations may increase or decrease resulting from physical changes affecting flooding conditions. As soon as practicable, but not later than six months after the date such information becomes available, the Floodplain Administrator shall notify the Federal Insurance Administrator of the changes by submitting technical or scientific data in accordance with Volume 44 Code of Federal Regulations Section 65.3. 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.

      H.   Engineer Certification:

         (1)   Require that for all new or substantially improved structures in an Area of Special Flood Hazard along the Boise River or in the gulches, a licensed professional engineer or registered land surveyor certify the actual elevation (in relation to mean sea level) of the lowest floor (including basement) of the structure; and record the certified elevation and whether or not the structure contains a basement.

         (2)   Require that for all new or substantially improved structures in an Area of Shallow Flooding in an Area of Special Flood Hazard, a licensed professional engineer or registered land surveyor shall certify the actual height in feet, as measured from the building edges at the lowest floor height to the highest ground which surrounds the building and record the certified height and whether or not the structure contains a basement.

         (3)   Require that for all new or substantially improved flood-proofed non-residential structures; a licensed professional engineer or registered land surveyor certify that the actual elevation (in relation to mean sea level) to which the structure is flood-proofed; and the Boise City Planning and Development Services Director shall maintain copies of the flood-proofing certificates as required in this chapter.

      I.   Permit Issuance: Issue building or grading permits for new construction, new development, and substantial improvement to structures which are in compliance with the provisions of this Ordinance.

      J.   Corrective Procedures: When the Floodplain Administrator finds violations of applicable State and local laws, it shall be his or her duty to notify the owner or occupant of the building of the violation. The owner or occupant shall immediately remedy each of the violations of law cited in such notification.
