This page provides resources and info to help local governments in California to pursue their own prohibition on new gas stations.
The main resource is this MODEL ORDINANCE that can be tailored to suit local circumstances.
The first city in the United States to institute a prohibition on new gas stations was Petaluma, California, approved unanimously on February 22. Their ordinance is complex and includes elements that address existing gas stations, which is unnecessary and invites complexity, controversy, and the potential for opposition. It is best to keep things as simple as possible – an ordinance that prohibits the construction of new gas stations. That said, here is the Petaluma Ordinance and attachments 1-7. And here is CONGAS’s Letter of Support for the prohibition.
