"All I'm thinking about is the folks whose lives have been devastated for a second time in two years".
Rescue workers were out in force across the little town, 13 miles west of Baltimore along the Patapsco River.
They face another mammoth cleanup and another daunting comeback.
The damage happens less than two years after business owners and residents were rebuilding from another massive flood that hit the area.
Water rescue trucks and ATVs are being used to help locate and rescue Eddison, and officials confirmed during a press conference that they're "making every effort" to locate him. The city's hub, Main Street, had to be rebuilt. To see the damage on Sunday was "heartbreaking and devastating", Mr. Miller said. "We'll just have to assess it", he said, speaking near a bridge where several crushed cars were swept into a muddy tributary's banks. At the height of the storm, the water had risen above the first floor of some buildings, Howard County emergency officials said. He said Hermond was trying to help others by holding a door open as brown floodwaters coursed through the restaurant when a woman approached, desperately trying to rescue her pet just outside.

The area was still in the process of rebuilding when waters overtook the city's roads once again on Sunday. Everyday people saved lives, too, helping neighbors trapped in cars and helping others evacuate.
Rescuers are searching for Eddison Alexander Hermond, 39, of Severn, who reported missing to Howard County police about 12:30 a.m. Monday.
"If you look at the devastation and the damage, I would certainly say it's worse than 2016", he said.
Ellicott City is no stranger to the destruction of flooding - two people died when a similar flash flood disaster blasted the town two years ago.
In parts of Ellicott City, more than 8 inches fell between 6 a.m. and 9 p.m. Sunday, the weather service said.
In July of 2016, a thunderstorm dropped more than a half of a foot of rain in just 2 hours.
