The cost of providing services to Westlake Village residents and businesses increases each year. Such services include law enforcement, park facilities and programs, street and sidewalk maintenance, and community events. The City is reliant on property tax and sales tax revenue to fund these services. If the annual increases in tax revenue do not keep pace with the annual increases in cost, the City will eventually be required to reduce the services it provides. Residential development projects increase property tax revenue by increasing the assessed property valuation and increase sales tax revenue by increasing the number of customers shopping at local businesses.
