Flood Risk Resources

Harris County Has Official Resources to Help You Understand Flood Risk

Harris County offers free flood risk information through HCFCD's website, including interactive maps, flood-zone lookup, and the MAAPnext updated modeling project.

Harris County Home & Property

HCFCD's Interactive Mapping Tools at hcfcd.org let you look up any address and see nearby channels, drainage basins, and flood-related project information. The Model and Map Management (M3) System shows detailed hydraulic models used for flood planning.

You can also look up the FEMA flood zone for any address at msc.fema.gov. These two tools — HCFCD maps and FEMA flood maps — can give you a fuller picture of flood risk than either one alone. Both are free. Use them before buying, renting, or building in Harris County.
