Disadvantaged Business Participation
Diversity, inclusion, equity, and relevancy are essential to MRCA’s ability to achieve protection of Southern California’s open space and recreation resources. The MRCA recognizes that there is a fundamental right of all people to equitably access Southern California’s rich environmental resources and participate in decisions that affect these resources. The historic pattern of environmental burdens borne disproportionately by disadvantaged communities can be altered through deliberate practices that increase inclusion and participation. MRCA’s purchasing power can be used to promote environmental equity, diversity, and inclusion in all forms.
In 2017, MRCA’s Governing Board adopted an Outreach and Advertising Policy for contracts and established a target participation rate for disadvantaged business enterprises of 20%.
