1. Set the footprint around Contra Costa County, not population assumptions
Contra Costa Centre is recorded as a census-designated place in Contra Costa County, California. Bosseo’s public page says firms can choose statewide coverage or only selected counties.
Recommended approach
Ask which parts of Contra Costa County the firm actually serves, whether it wants a county-only footprint, and which locations deserve a page based on service area, court relevance, and usable local information. Keep Contra Costa Centre distinct from the county and from any metropolitan area used in broader marketing decisions.
