How is the environment of Marin protected?
The environment of unincorporated Marin County is protected in a variety of policies and regulations adopted by the County and the State. Major policies protecting the County’s natural environment are located in the Marin Countywide Plan, which preserves wetlands, streams, open space, and natural ridge tops. In addition, the County administers the California Environmental Quality Act or CEQA [pronounced see’-kwuh]. CEQA requires evaluation of most development projects to determine whether significant adverse impacts on the environment will occur and what mitigation measures may be needed.
