Coyote Canyon Landfill Revegetation - Transportation Corridor Agencies

revegetation landfill post-closure plan Restoration Ecology

Coyote Canyon Landfill Revegetation project was part of the mitigation program for the San Joaquin Hills Transportation Corridor Project in south Orange County. Land IQ was responsible for managing 122 acres of coastal sage scrub mitigation for 5 years; coordinating management of the mitigation area with County of Orange Integrated Waste Management Department; and the overall requirements of the landfill post-closure plan. Responsibilities included:

  • Assessing development of the vegetation;
  • Managing landscape contractors;
  • Providing recommendations for re-seeding, weed control, and irrigation specifications.

Land IQ prepared annual performance monitoring reports and submitted them to U.S. Fish and Wildlife Service (USFWS) as part of the mitigation program. USFWS determined that this coastal sage scrub habitat met the performance criteria of providing habitat for successfully breeding California gnatcatchers, as set forth in the Biological Opinion. In 1999, a total of 40 California gnatcatchers successfully fledged from 12 resident pairs.
