(Fullerton) â As the world around us grows more crowded, Assemblywoman Sharon Quirk-Silva (D-Orange County) is working to preserve much needed open space. She wrote Assembly Bill 510 (AB 510) to provide funding to the Wildlife Conservation Board to be used for the purchase of land related to the West Coyote Hills Open Space Project. âNorth Orange County deserves its fair share of parks. This bill would help save the largest remaining open space in a highly urbanized area of Orange County and Los Angeles County, to be enjoyed by over 1 million people as a natural preserve,â said Assemblywoman Quirk-Silva.
