He said 53 out of the lot's 85 acres will go to the county to help mitigate the environmental concerns about the Normans Kill.
Another concerned resident said the wetlands, flood-line, landslides and the foot-plain were all issues that needed to be addressed.
The board echoed those concerns that the development of land is below a dam.
"You don't want to have large concentrations of people below a dam failure area," said Feeney.
He said, though, he was unsure if the possibility of a dam failure was enough to deny plans to build.
"It could just be a matter of disclosure," he added.
The board also discussed being proactive about warning potential residents of the hazard. Leaving that responsibility solely up to the developer was not something they were willing to do.
Another presentation for a three-lot subdivision of 19.6 acres on Lydius Street also garnered some public attention and dissent as well, but the board unanimously granted the proposal concept approval.
Several Lydius Street residents brought up concerns about the noise level if the tree line on Lydius street was compromised due to construction.
One resident, Jeff Smith, said he did not think it made sense to develop the land in the first place because similar property down the road has not sold in over a year. That property is on sale for $2 million, he said.
The board was concerned with how water would get to the homes and if a public sewer system would be available.
Mike Davis spoke on behalf of the developer, and said he believed grinder pumps, or a septic system, would most likely be needed, but public water would be accessible. He said the conditions for that type of system are optimal.
"Sand makes for a good septic system," Davis said.
