Chula Vista adopted measures aimed, in part, at reducing greenhouse gas emissions in new development. The measures emphasize compact neighborhood development, building-specific energy measures for new communities, as well as comprehensive project design criteria to reduce greenhouse gas emissions throughout the community.

While Fremont is a largely built-out suburban community, it has targeted remaining undeveloped and under-utilized sites for high density, mixed use, and transit-oriented development.

The Petaluma General Plan 2025 reflects planning goals across all its elements that are designed to mitigate future greenhouse gas emissions. Highlights include policies that encourage higher densities around a new regional rail system and in the central core, as well as greener buildings among existing and future development.

After two decades of expanding outward and reaching the limits of developable land, the City of San Diego’s recent general plan update incorporates a City of Villages concept that directs future growth to mixed-use communities that are pedestrian friendly and linked to regional transit.
