A group of New Port Richey neighbors say their neighbor's construction isn't just illegal, but it's costing them.
Adrian, who asked we not use his last name, says his neighbor started building in an area with wetlands more than a year ago.
"He has stopped the natural flow of water all the way back through the wetlands," he said.
According to Pasco Co. records, the property owner never got a permit to build on the land.
He now faces county and state fines ranging in the hundreds of thousands of dollars.
"It's been an uphill battle," said Adrian, "I've had to kick the can for over a year."
Steve Turner, another neighbor, thinks the construction is ruining the area's natural water flow and leading to higher flooding in the area.
"It's certainly adding to our problems here," he said, "we don't need it."
ABC Action News contacted the owner for a comment, but didn't hear back by the time of this publication.
Adrian and his neighbors just want to see the land back to how it used to be.
"I want it to be returned to what it's supposed to be designated originally," he said, "it's a Class 1 wetlands."
