Maryland Gov. Larry Hogan (R) has requested a federal disaster declaration for Howard County two weeks after flooding left two dead and decimated downtown Ellicott City.

Hogan already declared a state of emergency, but a presidential declaration would send federal funding to help rebuild the communities.

The U.S. Small Business Administration this week declared the county a physical disaster area, allowing businesses, homeowners and renters to apply for low-interest loans to repair flood damage. The Federal Emergency Management Agency has been helping assess damage.

The July 30 flood damaged dozens of buildings and swept up about 200 vehicles after six inches of rain slammed the flood-prone city on the Patapsco River.
