Free base layers for the counties we cover — live on the map, no download required. Below is live Napa County, California data, drawn in its real colors — plus live previews of our most popular paid layers. Toggle away.
Coverage is still going county by county — a layer marked not yet mapped is one we have not built for that county yet. The five base layers stay free for every county we cover. Everything beyond them — zoning, traffic counts, commercial, wetlands, HUD, soils & geology and the rest — is included with VMAP Pro, $49 a month for every county. See pricing.
Napa County is a single valley whose agricultural preserve, adopted in 1968, made it the template for California farmland protection and keeps roughly nine-tenths of the county in vineyard and open space. Nearly all development is confined to Napa, American Canyon and the small upvalley towns, with winery-use permits, the Measure J and P growth-boundary votes, and post-2017 fire insurance shaping every transaction.
