Construction of a system to control underground methane will begin early this month at the now-closed Yorba Park, at Chapman Avenue and Yorba Street. The Orange County Health Care Agency notified the city of the problem in September 1998, and the park has been closed ever since. From 1957 to 1960, the county used the 9.3 acres as a landfill. It turned the site over to the city in 1962.
The park will be opened after the system is installed and operating and park facility improvements are completed.
