Measure M
Environmental Mitigation Program

Wilderness Preservation
Working in collaboration with the State and Federal wildlife agencies, Measure M2's (M2) Environmental Mitigation Program allocates funds to acquire land and fund habitat restoration projects to offset the environmental impacts of M2 freeway projects.
This Program represents the culmination of years of collaboration and support of environmental communities.
In November 2010, the Board allocated $42 million to purchase open space in Orange County. To date, OCTA has acquired more than 1,300 acres in Brea, Laguna Beach, Silverado Canyon, and Trabuco Canyon. Collectively named the Preserves.
Additionally, a total of 12 restoration projects have been funded throughout Orange County. Approximately $10 million has been allocated to restore about 350 acres of open space land.
Together, this effort ensures 13 sensitive species are protected in their native habitat.
An endowment has been established to pay for the long-term management of the Preserves. Additional preserve acquisitions will be dependent on the sales tax revenue stream and a fully funded endowment, which is estimated by 2030.
