Township supervisors have also approved reducing the speed limit from 25 mph to 15 mph in the proposed Golden Meadows Estates development near Mertzville.
Manley Partners, of Pottstown, plans 11 homes on the 35-acre tract. The developer is referring questions about the toads to the state Department of Environmental Protection.
DEP spokeswoman Sandra Roderick says a neighborhood boy discovered the presence of Eastern spadefoot toads on the site. The 2- to 3-inch toads are considered an endangered species. The toads are nocturnal and can stay underground for weeks, but come out en masse during mating season or after a big rain.
Roderick says home buyers will be told the toads also are residents.
