The term “Redwood Empire” has been used to describe different areas in California.
In terms of what I have covered for the past 30 odd years it has meant the track and cross country leagues of the North Bay League, Sonoma County League and the Coastal Mountain Conference.
Beginning in the 2018/19 season schools from those leagues were realigned and those schools, plus some new and old members, are now in the North Bay League (Oak, Redwood divisions), Vine Valley Athletic League and the Coastal Mountain Conference.
They cover four of California’s 58 counties. Sonoma, Mendocino, Lake and Napa. These are all north of San Francisco.
We cover a very large area, about the size of the states of Connecticut and Delaware combined, but have a very small population, less than the city of San Francisco.

Here are the county breakdowns.
