Addresses are created by the County's Geographic Information Systems (GIS) Department during the building permitting process and sometimes the land disturbance process. The building permit/land disturbance application must include a site plan that shows the location of the structure to be addressed and the driveway and driveway access to the road it intersects.
Once the GIS Department receives the building permit application, the address is assigned based on the address ranges that are assigned to the road the driveway intersects. The GIS mapping software calculates the house number based on where the driveway intersects the road. In the case of older roads, the address ranges are not so uniform and have to be assigned “manually” based on already existing addresses. Several other departments review the permit as well before the address is assigned.
