Start with the Brentwood service boundary, not a presumed lead count
Your firm may serve Brentwood within Contra Costa County while also accepting matters from elsewhere in California. Those geographic choices affect how you label sources, assign inquiries and interpret performance. The Census identifies Brentwood as a municipality in Contra Costa County and records a 2020–2024 ACS 5-year population estimate of 65,208.
Recommended approach
Review the geographic fields in your website forms, call handling, chat and video intake. Decide whether Brentwood and Contra Costa County need distinct tags, whether California-wide inquiries follow another path, and which staff member owns each service area. Measure those categories from your own intake records before changing routing rules.
