Service Description: Study Boundary: This is the study boundary from the Western San Joaquin Valley Least Conflict Solar Energy Assessment conducted by The Nature Conservancy California chapter in 2013. The results of this analysis can help initially screen for environmental or agricultural considerations when considering options for energy facilities.

The study area for this assessment was chosen to encompass 1) all of the existing and proposed large utility-scale solar projects in the Western San Joaquin Valley, 2) all of the moderate to high suitable and high permeability kit fox habitat, including core, satellite, and recovery areas, 3) the Westlands Water District, an area that is commonly proposed as environmentally compatible for utility-scale solar development within the region, and 4) the Tulare Basin (west of Delano, CA), which is a priority conservation area for bird species and is not captured by kit fox suitability and/or permeability models. The study area is 5.7 million acres.

Westlands Water District: The Federal Water District boundaries database is cooperatively shared between the U.S. Bureau of Reclamation (USBR), Mid-Pacific regional office (MP), MPGIS Service Center and the California Department of Water Resources (DWR). The USBR maintains this database with the voluntary assistance of the Federal Water Districts. This database allows the USBR and DWR to display and analyze this information.

This database is not intended to be used as a land survey or representation of land for conveyance or tax purposes. The database is available to all users that may require this information. Federal Water District boundaries are areas where Federal contracts provide water to the district in California. This database is designed as a regions polygon database and is updated when sufficient number of changes have occurred to warrant an update. Updates are determined by the needs of the local office. Separate databases are used for maintenance purposes. Boundaries are continually being updated as changes are identified by the Water Districts. The boundaries are not current for all Water Districts found in the database at the same time due to the update methods employed. There may be conflicts in the boundaries between districts due to the time of update, the review process associated, and issues between each Water District. Other problems may be associated with Water District name changes that have not been updated. This database represents the most current and accurate understanding of the boundary location and current name of the Water Districts. Calculation of acreage should be performed on the individual districts or on the District region for all districts. Please ensure that the appropriate conversion value is used. This data is stored in meters. NOTE: This will be the last version of this database distributed in this format. The USBR will be moving this database into a Geodatabase format for all future releases.

The report that describes the methods, assumptions and processing of data from this assessment is: Butterfield, H.S., D. Cameron, E. Brand, M. Webb, E. Forsburg, M. Kramer, E. O’Donoghue, and L. Crane. 2013. Western San Joaquin Valley least conflict solar assessment. Unpublished report. The Nature Conservancy, San Francisco, California. 26 pages.

The objective of this assessment is to characterize the land use and conservation constraints and opportunities associated with siting solar energy facilities in the Western San Joaquin Valley. This approach identifies areas with high conservation value that are important to avoid when planning energy infrastructure, as well as areas of lower environmental conflict potentially suitable for development. While the approach we take focuses on refining the conservation values in the study area, we also classify the region’s agricultural resources using simple, broadly applicable classes to begin to assess trade-offs or synergies between agricultural production, habitat conservation and energy development. In our assessment of biodiversity conservation values, we focus on core and high quality habitat for multiple listed species, including San Joaquin kit fox, and emphasize the preservation of connectivity for kit fox and other wide-ranging species.
