History

  • 1963-1982 County leased approximately 670 acres from The Irvine Company (TIC) for use as a municipal solid waste landfill.
  • 1982 TIC contracted with Gas Recovery Systems (GRS) to construct and operate a gas recovery facility at the site. County continued municipal solid waste disposal activities.
  • 1990 County ceased waste disposal operations and closed the landfill.
  • 1991 A conservation easement was negotiated between the Transportation Corridor Agency (TCA) and TIC for a Coastal Sage Scrub (CSS) mitigation area maintained by TCA. Portions of site side slopes were planted and maintained by TCA as a CSS habitat mitigation area.
  • 1993-1994 Various Memorandums of Understanding (MOUs) were negotiated between TCA and the County to provide reimbursement to the County for maintenance costs associated with the CSS habitat conservation area.
  • 1994 County initiated final closure construction.
  • 1995 County completed site closure construction.
  • 1997 TIC commenced development of residential areas adjacent to the site.
  • 1998 The Local Enforcement Agency (LEA) issued a Notice and Order (N&O) to TIC/County/GRS for landfill gas (LFG) migration control and requested an update of the Post-Closure Maintenance Plan (PCMP). An Additional MOU between TCA/County was negotiated for additional habitat conservation area costs.
  • 2000 The updated PCMP was submitted to the LEA.
  • 2002 The site was annexed by the City of Newport Beach.
  • 2003 TIC entered into discussions with the Newport Coast Advisory Committee regarding the potential construction of a Community Center adjacent to the site. TIC and County entered into discussions regarding potential County assumption of LFG monitoring and control activities at the site.
  • 2005 Leasehold boundaries at the site were adjusted at TIC’s request to accommodate TIC’s development of adjacent sites.
  • 2006 The site was conveyed to the County by TIC.
  • 2007 Construction of the adjacent Community Center was completed. The Final PCMP (FPCMP) for the site was approved by the Regional Water Quality Control Board (RWQCB), the California Integrated Waste Management Board (CIWMB) and the LEA.
  • 2008 County completed Phase 1 and 2 site security improvement projects. The LEA issued the Closure and updated Solid Waste Facility Permits for the site.
  • 2009 No unusual activities.
  • 2010 County approved Easement Deed and Agreement with Irvine Ranch Water District to County property to install and maintain the reclaimed water pipeline. The changeover to reclaimed water will save approximately 120,000 gallons of potable water per day.
  • 2011 Construction of improvements to the West Channel were completed.
  • 2012 Preliminary discussions are beginning regarding the development of a golf course on the top deck of the landfill.
