One of the towns hardest hit was Felton - a town underwater.

"This was bad," Felton resident Cindy Pressley said. "I knew it was going to be bad because everything is so saturated."
Drone video captured homes completely surrounded by flood waters from the San Lorenzo River.

The river hit its crest of 24.52 feet around 7:45 this morning, the second highest mark in modern history dating back to 1937.
Water began to recede after that, but residents in the area who did not evacuate had no place to go.
"We had the trifecta with the mudslides, and the trees down and the flooding," Pressley said. "So we are kind of trapped up here in our one way out Canyon."
Cindy Pressley lives in the Lompico Canyon area of Felton.

Neighbors sent us some of those images of flooding, slides and other major storm damage.
Elsewhere in Felton, some of the iconic town sights, like the landmark covered bridge, were completely flooded.
A notorious flood in 1982 was the worst ever for this area, the river hit 28.8 feet then.

Pressley says this storm has many similarities and she's concerned she will be stuck here for awhile.
"It's one way out, so we're here for the long-haul," Pressley said. "It might be days. In the past it has been days because we're kind of out here in Lompico, so they don't often get to us."
Not many people will be getting in and out of the area anytime soon due to other closures throughout the area.
We tried several paths to get down to Felton today. But many roads, like Highway 17 at Glenwood Drive, were shut down due to slides.
Bryan Zailer was supposed to go to over the hill for work, but he says it's just not safe do so today, especially on the smaller roads.
"They'll have trees that go over them, they'll have mudslides," Zailer said. "When I went through Mt. Charlie 6 years ago, I had a tree on one side of me and I was looking straight down the cliff on one side because it had washed out. You'll get up there and get pinned if it gets shut down you know?"
"So, nowhere you want to be when it's raining like this?" ABC7 News Reporter Dustin Dorsey asked.
"Oh, no. No," Zailer said.
Caltrans says it's unclear when Highway 17 Southbound may reopen. But workers we spoke with at the closure on 17 said it might be tomorrow.
