1. Turn Calabasas into a service decision, not a population claim
Calabasas is a city in Los Angeles County. The Census population estimate can help identify the place being discussed, but it cannot establish that residents need a particular legal service or that a page will attract inquiries. Your first decision is therefore operational: which services do you actually offer to people in Calabasas, and which services can you support across Los Angeles County? A page for a service you do not practice, or a city you do not serve, creates a relevance problem regardless of page count.
Recommended approach
Give Bosseo a current list of practice areas, legal services and accepted geographic boundaries. Review Calabasas as one city within Los Angeles County, then decide whether the appropriate footprint is Calabasas only, selected county cities, the county, or a broader California area. Do not use the population figure as a substitute for demand research.
