2026 Napa County Baseline Data Report (BDR)

Preliminary land use evaluation done for the 2026 Napa County Baseline Data Report (BDR), made to represent existing conditions of land use in Napa County. This layer represents initial land use evaluation done for the 2026 BDR. Future evaluations are expected as part of the General Plan Update (GPU) to inform the GPU, and is not meant to represent the current or potential future General Plan land use map. Currently it is a baseline of existing conditions across the county, made by replicating 2004 methodology previously used to create the tables and maps of "Existing Land Use" for the 2005 Napa County BDR.
