(1) Roads. All public and private roads in Clallam County which serve addressable properties or structures will be signed in accordance with the standards of the Department of Public Works. Private road signs will identify the road as private.

(2) Mileposts. Permanent mileposts will be placed on all county roads longer than one mile. These will indicate distance in miles from the designated road origin.

On each road without a readily recognizable origin, a permanent milepost will also be placed near the beginning of the road showing the address distance at that point.

Permanent mileposts will conform to the standards of the Clallam County Department of Public Works.

(3) Addresses. Each addressed site will be provided with a sign showing the address number in white reflectorized numbers on a green reflectorized background. The sign shall be posted in accordance with the standards of the Clallam County Department of Community Development. Although the sign will remain the property of Clallam County, the addressee may relocate or mount the sign in any way that is consistent with the above standards.

Where necessary, additional address signs may be provided to identify individual sites on a common driveway.

(4) Road Origin Reference Points. In order to facilitate ongoing consistency of measurements, a road origin reference point may be established near the beginning of the road. The reference point will be a fixed object, such as a road or traffic sign. The reference point will be identified in a road index, along with the address distance, in thousandths of a mile, from the road origin. The distance may also be posted on a road or traffic sign post. It will show the address distance, in thousandths of a mile, and must be readable by the driver of a vehicle proceeding onto that road.

Road origin reference points will be established in any case where use of the centerline to initiate measurement presents a significant hazard, including all roads originating from US 101 or SR 112. Road origin reference points will be established for any road whose precise point of origin is ambiguous.
