Free base layers for the counties we cover — live on the map, no download required. Below is live Contra Costa 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.

Growth has pushed steadily east along Highway 4 into the county's last large greenfield sites, with the voter-approved Urban Limit Line, Delta levee and flood constraints, and refinery-transition planning shaping where the next decade of housing lands.
