Summary
Dade City's floodplain ordinance requires the floodplain administrator to pin down a base flood elevation before permitting flood-hazard-area development. Where FEMA's maps show a zone A area without a published elevation, Code § 50-32 sets a fallback: two feet above the highest adjacent grade unless deeper flooding is documented.
Sec. 50-32. - Information in flood hazard areas without base flood elevations (approximate zone A). Where flood hazard areas are delineated on the FIRM and base flood elevation data have not been provided, the floodplain administrator shall: ... (3)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:a.Require the applicant to include base flood elevation data prepared in accordance with currently accepted engineering practices; orb.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.

Full Breakdown
Chapter 50, the Floodplain Management Ordinance adopted by Ord. No. 2014-07 on August 12, 2014, designates the Dade City Building Official as floodplain administrator under § 50-14. When a parcel sits in an "approximate zone A" area, meaning it's delineated on the FIRM but FEMA hasn't published a base flood elevation for it, § 50-32 gives the administrator a sequence of options: require the applicant to supply engineering-based elevation data, obtain and use available federal or state data, or, where no reliable data exists, treat two feet above the highest adjacent grade as the base flood elevation, provided there's no evidence flood depths could run deeper.
If an applicant's data will be submitted to FEMA to change the map, the analysis must be prepared by a Florida-licensed engineer in FEMA's required format, with the applicant covering submittal and processing fees under § 50-32(4). This determination controls real construction decisions: lowest-floor elevation certifications required under §§ 50-37 through 50-40 for buildings exempt from the Florida Building Code are measured against whatever base flood elevation gets established this way, and § 50-31 requires site plans to delineate base flood elevations and flood zone boundaries before a permit issues.
The chapter's variance process runs through the development review committee under §§ 50-41 through 50-48, with a further appeal path to the Sixth Judicial Circuit Court in Pasco County.
Violations & Fines
A parcel in a mapped zone A area with no published elevation cannot get a floodplain development permit until the base flood elevation is established under one of § 50-32's methods. Building without an approved lowest-floor elevation certification risks permit suspension or revocation under § 50-29, since the floodplain administrator inspects lowest-floor placement before vertical construction can continue.
