Willis faces significant flood risk as a growing city in northern Montgomery County's San Jacinto River watershed. FEMA flood zone maps identify affected areas. Development in flood zones requires permits from Montgomery County Floodplain Administration.
Willis is located in northern Montgomery County within the San Jacinto River watershed. The city experienced significant flooding during Hurricane Harvey (2017) and subsequent storm events. Properties near Willis Creek, the West Fork San Jacinto River tributaries, and low-lying areas are in FEMA flood zones.
