While some people are already cleaning up after flooding from Hurricane Irma, other people are watching water still rising around their homes.

For many residents who live near Lake Harney, which straddles the Volusia-Seminole line, it's the second time they've had to deal with flooding.

The Piland family's home already flooding once during Hurricane Irma.

"We made precautions, had the pumps, the sandbags, but it overtook it," Marie Piland said.

The water went down, but now it's going back up as all the rain that Irma dumped down south is moving up the St. Johns River. Piland's family is now trying to build several walls of sandbags to save their home.

They got some much-needed help from Seminole County deputies, who drove a truck through several flooded streets Thursday to deliver sandbags.

"Oh my God, it saved us so much back-breaking work," Piland said. "My legs — I've been doing this since Saturday, so thank God."

Some people already evacuated. Floodwaters are already covering some peoples' properties.

Those whose homes sit high enough worry flooded roads could cause them to be stranded in their homes. Florida Highway Patrol troopers are keeping a close eye on State Road 46, a busy road they might have to close if water begins to cover it.

Piland is nervously watching the water rise.

"Hopefully, this will stop it and we can stay high and dry up top," she said. "Hopefully, we'll get it right this time."

Floodwaters from the St. Johns River are expected to crest Thursday night into Friday morning.
