Floodplain Elevation Tool
Introducing Walter P Moore's Floodplain Elevation Tool — an interactive tool designed to provide FEMA 10-year, 50-year, 100-year, and 500-year frequency floodplain elevations and stream flood profiles within the watersheds of Harris County and the City of Houston. Useful when planning urban development and evaluating flood risk, this tool incorporates the new Harris County and City of Houston floodplain regulations.
