But commissioners said they were required to abide by the flood maps on file.
“According to the maps, the development proposed is acceptable,” commissioner John Heard said.
The homes, which were approved unanimously, will be part of what is known as an open space conservation subdivision. Of the 93 acre property, 39 acres will be preserved as green space, said Eric Johansen, who represented the developer. The subdivision also will have a boat ramp for public access to the Yellow River and a swimming pool and tennis courts.
To help appease flooding worries, each home will have a personal cistern that can hold 300 gallons of water.
Michael Shapiro, who lives nearby and who tried to get commissioners to delay their vote, said he is in favor of development, but thought the project could be harmful to the environment. Residents had asked the county to buy the land for a park — at the recommendation of a planning commissioner, who referenced the county’s purchase of Simpsonwood in Peachtree Corners — but Howard said there was not a need for additional park land nearby.
“I’m impressed with the passion in the area,” she said. “There are serious issues in the area that really need to be addressed, but they have nothing to do with this zoning.”
