Where flood hazard areas are delineated on the FIRM and base flood elevation data have not been provided, the Floodplain Administrator is authorized to:
A. Require the applicant to include base flood elevation data prepared by a qualified CA Licensed Civil Engineer in accordance with currently accepted engineering practices. Such analyses shall be performed and sealed by a qualified CA Licensed Civil Engineer. Studies, analyses and computations shall be submitted in sufficient detail to allow review and approval by the Floodplain Administrator. The accuracy of data submitted for such determination shall be the responsibility of the applicant.
B. Obtain, review, and provide to applicants base flood elevation and floodway data available from a federal or state agency or other source or require the applicant to obtain and use base flood elevation and floodway data available from a federal or state agency or other source.
C. Where base flood elevation and floodway data are not available from another source, where the available data are deemed by the Floodplain Administrator to not reasonably reflect flooding conditions, or where the available data are known to be scientifically or technically incorrect or otherwise inadequate:
(1) Require the applicant to include base flood elevation data in accordance with Section 8.79.270A. of this chapter; or
(2) Specify that the base flood elevation is two (2) feet above the highest adjacent grade at the location of the development, provided there is no evidence indicating flood depths have been or may be greater than two (2) feet.
D. Where the base flood elevation data are to be used to support a request for a Letter of Map Change from FEMA, advise the applicant that the analyses shall be prepared by a qualified CA Licensed Civil Engineer in a format required by FEMA, and that it shall be the responsibility of the applicant to satisfy the submittal requirements and pay the processing fees.
