Description
The District boundary definitions are primarily based on the county boundaries. 2010 Census TIGER/Line county data were used to create this district boundary layer. Following the Census data, for the coastal counties, new District data use three-mile offshore lines instead of the coastlines that the old Caltrans District data had been used.
