INTERACTIVE TOOL PROVIDING UPDATES ON FLOODPLAIN MODELS FOR HARRIS COUNTY

All FEMA effective floodplain maps for Harris County are available through the M3 system.

The Harris County Flood Control District’s Model and Map Management (M3) System is an interactive tool designed to communicate and share changes to the Federal Emergency Management Agency’s (FEMA) effective floodplain models for Harris County. The goal of the M3 System is to distribute FEMA effective models to the general public, track ongoing changes to the models resulting from development projects, and facilitate communication between FEMA, Harris County Flood Control District, Local Floodplain Administrators, and the community.
