(a) Permanent urban address grid boundaries will be established, in consultation with the municipality involved, such that there will be no possibility of duplicate address numbers on any road. Wherever possible, said boundaries will be established to include entire roads in only one system.

(b) Where a road, or the projection of a road crosses an urban grid boundary, a false origin may be established such that the range of address numbers within the urban address grid does not overlap the range of numbers outside the urban address grid.

(c) If the urban grid boundary follows a road, both sides of that portion of the road will be addressed in the same system. Either both sides of the road will use rural addressing, or both sides will use urban addressing.

(a) Recognizing that it is in the mutual interest of all jurisdictions to prevent addressing conflicts, municipalities within Clallam County are respectfully requested to maintain compatibility with the above guidelines in the course of any future annexations, and any modification to, or implementation of their own addressing ordinances.

(b) Emergency dispatchers will be provided with address information on all roads that cross the city limits sufficient to rapidly and simply determine whether a given address is inside the city.

(c) Comment will be requested from all relevant emergency response agencies on any city-county addressing coordination policy before it is implemented.
