Summary
When FEMA's maps place a Cape Coral parcel in a flood hazard area but list no base flood elevation, Section 9.4.2 puts the Floodplain Administrator in charge of setting one: certified engineering data first, then federal or state agency figures, and, absent both, a default of two feet above the site's highest adjacent grade.
Where flood hazard areas are delineated on the FIRM and base flood elevation data have not been provided, the Floodplain Administrator shall: A.Require the applicant to include base flood elevation data prepared in accordance with currently accepted engineering practices. ... 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: 2.Specify that the base flood elevation is two 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 feet; and

Full Breakdown
2 of the Floodplain Management Ordinance. The Floodplain Administrator first requires the applicant to submit base flood elevation data prepared under currently accepted engineering practices, or obtains that data from a federal or state agency. 2(C)(2) lets the Administrator instead set the base flood elevation at two feet above the highest adjacent grade at the development site, provided nothing indicates flood depths could exceed two feet there. 2(A) engineering process, not the two-foot default. 3(B)). 8(D)).
Violations & Fines
A variance cannot be granted for floodway development if it would raise the base flood elevation, as shown by the Section 9.4.3 analyses (Section 9.6.4). Separately, any building lacking documentation of its lowest-floor elevation relative to the base flood elevation is presumed a violation of Article 9 under Section 9.7.1 until that certification is produced, exposing the owner to a notice of violation or stop-work order from the Floodplain Administrator.
