Orange County studying buying remaining private wildlife areas in county
With at least $42 million available from a transportation bond measure OK'd by voters, Orange County's transportation agency published a list of wild areas they seek to purchase as "mitigation" for various highway projects. Around 3400 acres are on the agency's "high priority" list, and are shown in green on the map below.
In the first wave of purchases, almost 600 acres was saved in Trabuco Canyon in the south end of the county (#'s 22, 56 and 66 on the map below), and 300 acres saved in the city of Brea (Hayashi property--#28 on the map) in the Chino Hills. Here is a report with more details:
