California Environmental Quality Act (1970)
California enacted a law requiring state and local agencies to study the environmental effects of discretionary projects before approving them. Governor Ronald Reagan signed it in 1970. The law's guidelines carve out categorical exemptions, including Class 1 for existing facilities, which covers projects with no meaningful physical change to the site.
Agencies began preparing environmental impact reports and negative declarations for major projects.
CEQA became a routine checkpoint in California land-use approvals and a frequent subject of litigation over whether exemptions were properly applied.
The Thomas Road tentative map is filed as exempt under Section 15301(k), Class 1, meaning the city concluded the subdivision involves existing facilities and needs no full environmental review. How that exemption is applied is often the point of challenge when a subdivision is contested.
