(1) Use of Existing City Addressing Systems. Wherever practical, the existing address systems of the municipalities in Clallam County will be incorporated as components of the Clallam County 911 addressing system. Permanent boundaries will be established for the extension of each urban address grid beyond the current city limits of each municipality. Addressing within that boundary will be compatible with the municipality’s addressing system.

(2) Modification of Existing City Addressing Systems. Municipalities may be requested to make certain modifications to their addressing systems in order to insure long term compatibility between addresses inside and outside of that jurisdiction. The Director of the Clallam County Department of Community Development is authorized, on behalf of Clallam County, to develop interlocal agreements with other jurisdictions within the county which will coordinate the transition between urban and rural addressing in the applicable areas.
