CPAD and CCED are produced and managed by GreenInfo Network. Questions and comments about CPAD and CCED should be directed to cpad@calands.org.


Work on CPAD and CCED is currently funded through 2020 by the California Natural Resources Agency and the California Department of Water Resources. Thanks to this generous support, GreenInfo Network can keep these important datasets up to date, responsive to user needs, and representative of best practices for open data.

The CPAD and CCED datasets are the result of work by many groups and individuals. GreenInfo Network greatly appreciates the contributions of time and data from hundreds of agencies and nonprofits, as well as the funding support of sponsors (see below), and the support of Esri for donations of ArcGIS software used to maintain CPAD and CCED data.

GreenInfo also acknowledges those originally involved in developing databases that eventually merged into the first CPAD in 2007. These pioneers have been essential to the success of CPAD and include John Woodbury, original coordinator of the Bay Area Open Space Council; and Darla Guenzler of the California Council of Land Trusts. In addition, GreenInfo’s longstanding partnership with the Bay Area Open Space Council has been essential to the development of these datasets.

GreenInfo Network has  worked over many years in partnership with the USGS Gap Analysis Program (GAP), which has supported developmental work on CPAD as it relates to the Protected Areas Database of the United States, and we appreciate their engagement and support.

During 2012-14, support for CPAD and CCED came through the California Strategic Growth Council, in collaboration with the USGS GAP. This project greatly improved CPAD data, including expansion of available easement data, refinements to the CPAD data model to better meet user needs, more outreach and coordination with agencies and organizations with CPAD holdings and recommendations for long term support of CPAD.
