Interactive Mapping Tools

Model and Map Management (M3) System

The Harris County Flood Control District’s Model and Map Management (M3) System is an interactive tool designed to manage 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.
