Process step:
Process description:
DFIRM DLG data files imported into Arc/Info using DLGARC command to create firm-flood coverage. Firmzones coverage created as a subset from the firm-flood coverage. Refer to metadata for firm-flood coverage for methodology used in creation of firmzones data layer.
Modifications to Data Layer:
Zone A, AE, and X attribute assignment performed by Jay Johnson, City of Tallahassee Stormwater Department Refer to metadata for firm-flood coverage for attribute assignment methodology.
Supplemental_Information:
Digital FIRM data primarily intended to assist in the identification of risk zones and Special Flood Hazard (Areas (SFHAs) shown on the hardcopy Flood Insurance Rate Maps (FIRMs). Specifications of the digitizing of the FIRMs to create the DLG-3 thematic flood risk overlay are consistent with those required for mapping at the scale of 1:24,000. Users should assess the horizontal positional accuracy of DFIRMs with regard to the selected base map source and the requirements of the application (Source: Intended Use and Positional Accuracy sections in DFIRM metadata provided with original DLG DFIRM data files).
