of California's 482 city and 58 county general plans

Land-use impacts the health of people and the environment. Decisions happes at the local level. In California, a planning document, called a “general plan” sets forth zoning and policy goals for each city and county. This plan determines how much development will occur, what type of development (eg. single family homes, mixed-use commercial) and where. Plans are collaboratively created by communities over many years and many public meetings. Resulting documents are often hundreds of pages in length.

This research project created the first public-facing, searchable database of general plans – enabling citizen scientists to comprehensively assess plan contents and make recommendation to their own jurisdictions based on practice already in place elseswhere. The landmark database covers 481 (of 482) California city-level and all 58 county general plans. Working with California state agencies (the Governor’s Office of Planning and Research, Housing and Community Development and Air Resources Board) and non-profits (California Environmental Justice Alliance and Communities for a Better Environment), we have developed a search engine portal (PlanSearch.caes.ucdavis.edu) where plans can be queried. This website allows community members, state agencies and planners to rapidly compare across plans, helping to foster transfer of policy and a ‘keeping up with the Jones” attitude in pushing the boundaries of planning.

This landmark state-level database of general plans is the first for California- and nationally.

Please reach out if you would like collaborate and add your state to the database. We provide our model in open source code in GitHub for others that wish to build similar planning data infrastructure.

    • We review Environmental Justice policies across all of California’s city plans. We find that cities that are majority communities of color have pioneered the most EJ content and the earliest. This suggests that communities that are not majority of color will need to take more intentional steps to foster representation as they craft health equity policies.

    • We extracted the text of all plans and explored the topical focus of plans using natural language processing techniques. California cities address 60 different topics and a quarter of those topics are regionally specific. We identify a rift in how plans address housing and how they address all other topics.
