Rural Addressing

The GIS department also handles Rural Addressing. Properties inside of the city limits of Whitehall and Boulder are addressed by those cities and not through the county. New Addressing standards have been in place for two years to increase the accuracy of mapping 911 calls and routing emergency response. Unfortunately some property addresses have had to be reassigned. We apologize for the inconvenience and greatly appreciate the landowner cooperation we've received!
