Humboldt County, California
Humboldt County centers on Eureka and Arcata on Humboldt Bay, with redwood timberland behind it and Cal Poly Humboldt as a growing anchor. The post-legalization cannabis contraction reshaped the rural land market, and coastal-zone permitting, tsunami and sea-level-rise mapping around the bay, and long distances to any other market define the county's development limits.
