- BFE data required for subdivisions >50 lots or 5 acresacre43,560 square feet — about the size of an American football field without the end zones.50 lots
Base flood elevation data shall be obtained from other sources or developed using detailed methodologies comparable to those contained in a FIS for subdivision proposals and other proposed development proposals (including manufactured home parks and subdivisions) that exceed fifty (50) lots or five (5) acres, whichever is the lesser.
- Base flood elevation determination
For these areas, the base flood elevations and floodway information from Federal, State, and other acceptable sources shall be used, when available. Where the specific one percent (1%) annual chance flood elevation cannot be determined for this area using other sources of data... then the applicant for the proposed use, development and/or activity shall determine this base flood elevation.
- Lowest floor elevation to BFE + 18 inches18 in
When such base flood elevation data is utilized, the lowest floor shall be elevated to or above the base flood level plus eighteen (18) inches.
From the ordinance
The A zone on the FIRM accompanying the FIS shall be those areas for which no detailed flood profiles or elevations are provided, but the one percent (1%) annual chance floodplain boundary has been approximated.
