Flooding
Flooding is the most frequent severe weather event and the costliest natural disaster. As climate change progresses, Montgomery County is taking steps to better understand flooding risks and working to reduce these risks. Each page below has useful resources to help prepare for an event before, during, and after a flood.
The During a Flood page has information on frequently flooded roads and how to report flooding to the County.
The Flood Management page provides background on the County's Comprehensive Flood Management Planning (CFMP) process and flood modeling. You can find the Flood Risk Explorer here, which shows the results of modeling the Sligo Creek watershed, the first of eleven watersheds to be modeled. The Flood Risk Explorer will be continually updated as new models are finished.
The Resident Portal lays out steps residents and businesses can take to reduce flood risk such as making plans before severe storms occur, making properties safer, and purchasing flood insurance.
