Major update for CCED 2016


The 2016 release of CCED is a substantial improvement in the effort to track easements in California. Large additions in number of easements tracked, acreage covered, and agencies included have led to a more accurate database. Improvements to technical methods, and a significant review effort, allowed for the removal of duplicate (stacked) easements.

What we accomplished: 
  • Added 500,000 acres of new easement data.
  • Added 100+ new agencies, including: California Department of Fish and Wildlife, California Tahoe Conservancy, Golden State Land Conservancy, Homeowner Associations (various), Marin Agricultural Land Trust, Riverside Conservation Authority.
  • Updated data for over 50 agencies, including: American Farmland Trust, Ducks Unlimited, Trust for Public Land, The Nature Conservancy, National Conservation Easement Database, and Wildlife Conservation Board.
  • Acquired permission to include California Department of Fish and Wildlife data.
  • Included over 7,000 easements in San Diego from SanGIS and SANDAG.
  • Removed duplicate easements (easements reported by multiple agencies). Secondary easement holders are now tracked in the field s_esmthldr1. Note: small slivers remain in some areas when the overlapping is less than 100 acres.
  • Conformed attributes to the NCED national data framework, all data received was processed to standardize fields and attributes.
  • Standardized core fields: easement holder (agency name), access, county.
  • Developed agency level tracking for possible easement holders in California and outreach.

What's new in CPAD 2016b?


Our focus for the 2016b update to CPAD was adding new urban parks, improving standardization (park names, correcting “unknown” access data, removing overlapping geometries), and monitoring acquisitions and transfers made by the top land-owning agencies in California. As we keep an eye on newly-protected lands, we also return to older data and make improvements. 

What we accomplished: 
  • Added new land acquisitions made by the top 50 agencies in CPAD, such as: Peninsula Open Space Trust, San Diego County, City and County of San Francisco, San Mateo County, Santa Clara County, Los Angeles County, Sonoma County Agricultural Preservation and Open Space District, and the Midpeninsula Regional Open Space District.
  • Made significant improvements to parcel alignment in San Mateo County and Orange County.
  • Added dozens of new city parks, in cities across California - Los Angeles, San Diego, Fresno, Cupertino, Fremont, Temecula, Clayton, Davis, Elk Grove, Kingsburg, Redlands, Arcata, Santa Rosa, Chino, Chino Hills, Corona, Huntington Beach, Newport Beach, Loma Linda, Yorba Linda, and more.
  • Expanded abbreviations in the Park Name field (names are still abbreviated in the Label Name field) to facilitate better querying.
  • Reviewed data accuracy in San Joaquin and Mariposa Counties.
  • Reviewed and improved park data along the Santa Ana River Parkway corridor.
  • Improved the stability and reliability of the Unit ID structure by condensing dozens of duplicate unit records.
  • Started the process of eliminating the “Unknown Access” category.
  • Added Date Established data for many Holdings.
  • Made revisions to correct overlapping geometries.

The California Protected Areas Database (CPAD) is a GIS inventory of lands protected primarily for open space uses through fee ownership by federal, state, regional/local agencies, and by private conservation organizations. Some lands in CPAD may be subject to transfer or disposition for other non-resource uses over time, and some may have restricted public access. The first version of CPAD was released in May 2008.

The California Conservation Easement Database (CCED) contains lands protected under conservation easements. It is a parallel data set to CPAD which covers protected areas owned in fee. The first version of CCED was released in April 2014.
