12.04.010 Uniform address numbering system adopted.

There is adopted a uniform address numbering system that shall apply to all roads and properties within the county. (Ord. 464 § 1, 1987)

12.04.020 Administrative authority.

The uniform property numbering system shall be initiated, continued, operated and maintained by the county surveyor and all numbers assigned shall be in accordance with this chapter. It shall be the duty of the building department to require the installation of numbers as required by this chapter prior to the issuance of a final inspection permit on any new construction completed after the effective date of sub-index maps for the area in which the construction is taking place. (Ord. 464 § 5, 1987)

12.04.030 Index of roads.

A. A master index, which may include maps, shall be adopted by resolution of the board of supervisors showing the point of beginning for all roads, streets, private roads and highways within the county.

B. Sub-index maps shall be prepared by the county surveyor showing details of precisely numbered areas. These maps shall then be maintained as necessary by the county surveyor to designate the numbers and location of numbers assigned to particular buildings. These maps shall become effective on completion or revision by the county surveyor. (Ord. 464 § 2, 1987)

12.04.040 Numbering of roads.

Each road shall be numbered one thousand numbers per mile along its length. The numbering shall begin at zero where the road begins at a state highway or other road and shall continue numbering at one thousand per mile until the road ends. Even numbers will be to the left side of the street in the direction of increasing numbers. (Ord. 464 § 3, 1987)

12.04.050 Naming of roads.

All streets and roads, whether public or private, whether dedicated or not, and county highways (all hereinafter referred to as “roads”) shall be named pursuant to this section and such roads shall be known by the name assigned. No road shall be deemed officially named unless it has been approved by the board of supervisors by order duly made and reflected in its minutes or by resolution. All official names existing on the effective date of the ordinance codified in this chapter shall remain the same until changed according to law including this chapter. The public works department shall maintain a list of all road names so approved, or in existence and shall certify to the board of supervisors that no name submitted for approval duplicates or so closely approximates an existing name as to cause confusion. The public works department shall initiate a program to name officially all existing roads for which no name has been officially assigned and shall cause any future roads to be officially named. Where unofficial road names exist or are commonly used on the effective date of the ordinance codified in this chapter they may continue to be used and the public works department shall initiate their official naming; provided that they are not in conflict with existing official names. Where a public hearing is required to officially name, or change the name of a road, the public works department shall initiate such a hearing before the board of supervisors. No subdivisions or divisions of land shall be approved until all the roads therein or contiguous thereto have been officially named by the board of supervisors after initiation by the public works department. A road may bear one name for its entire length; or where a road changes direction by ninety degrees a different name may be adopted for such changed direction to facilitate its numbering. (Ord. 464 § 4, 1987)

12.04.060 Display of address numbers.

After the effective date of any subindex map, or revision thereof, the county surveyor shall give written notice to the owner or occupant of buildings or land which are assigned, or reassigned numbers pursuant to this chapter, which notice shall contain the new number assigned. Written notice may be given by posting, personal delivery or first class mail. Notice for new construction shall be given to the building department which shall require display of the number prior to the issuance of a final inspection permit. Within thirty days after the county surveyor has given notice, the owner or occupant of the building or property shall cause the number to be displayed on the building or land in such manner as to be visible from the street or road on which the building or land fronts and shall remove or obscure from public view any old or previous numbers not in accordance with this chapter, provided, however, that where buildings are removed a considerable distance from any public street or road, such driveway leading to such building; provided further, that in rural areas where rural free delivery of mail is provided, the number may be displayed upon receptacles designed for the delivery of mail where the receptacle is in the proximity of the roadway or driveway leading to the building. Numbers shall be maintained in a neat and orderly manner so as to remain readable. Numbers displayed shall be a minimum height of four inches, shall not exceed a maximum height of one foot, a minimum of four feet above ground, and not to exceed eight feet unless approved by the board of supervisors, and shall be of a contrasting color from the basic background. (Ord. 464 § 6, 1987)

12.04.070 Legal description of property not affected by provisions.

The adoption and implementation of this chapter shall in no manner affect the legal description of any property. (Ord. 464 § 7, 1987)

12.04.080 Violation—Penalty.

Any person, either owner or occupant, firm, partnership, copartnership, corporation, whether as principal, agent or employee, failing or refusing to display any assigned number or displaying or permitting to be displayed a number not assigned, or removing or failing to maintain an assigned number shall be guilty of an infraction. (Ord. 464 § 8, 1987)
