A real, documented, repeated flood history

The historic Main Street corridor suffered catastrophic flash floods in 2011, and then two separate "1,000-year" events within two years of each other: July 30, 2016 (2 fatalities) and May 2018.

The mitigation program remains unfinished

Howard County's Safe and Sound flood-mitigation program has completed three retention ponds and is still constructing a mile-long underground bypass tunnel; total cost had grown to a real, disclosed $386 million by July 2026.

Maryland's statewide insurance range applies elsewhere

For Ellicott City's broader, non-Main-Street housing stock, no distinct premium figure was found this pass -- confirm current, address-specific quotes directly, and separately confirm FEMA flood-zone status for any Main Street-adjacent property.
