A major component to the Arroyo Trabuco Golf Club is the preservation of approximately 350 acres, representing over half of the project site, as open space. Environmental components to the plan include an extensive revegetation program, a number of measures to assure the protection of water quality in the Arroyo, and elaborate efforts to protect area wetlands. As identified by its current alignment, the golf course impacts less than one-half acres of wetlands and very little sensitive habitat. No threatened or any endangered species is directly impacted by the golf course.
