Display Field: DFIRM_ID

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: FEMA Coastal Transects contain information about the Coastal Transect Lines within the flood risk project area, if applicable. The transect lines indicate the location that was used to provide representative topographic information for the coastal flood models used. Hydraulic analyses of coastal flood effects are executed along transects, which are cross sections taken perpendicular to the shoreline, representing a segment of coast with similar characteristics. Transect elevations are interpolated to delineate the coastal flood zones. The spatial elements representing coastal transects are lines that generally extend from offshore all the way across the coastal floodplain. Transects can also extend seaward when wave runup modeling is used to determine coastal flood hazards. This information is needed for the Transect Locator Map table and Coastal Transect Parameters table in the FIS report.
