or the major unit line or lines if no numbers have been previously established on adjoining properties. For purposes of determining whether a number shall be odd or even, it is determined that even numbers shall be on the right-hand side of the street or road and odd numbers on the left-hand side of the street or road in the direction of increasing magnitude of numbers. Where existing numbers have been established prior to this article and the odd or even numbers exist in reverse order on the sides of the street or road, the reversed order of odd/even number location shall remain as it presently exists and shall continue for any extension of the street or road. (Prior code § 23.11)

§ 15.08.070. Name of streets.

No street or road crossing any of the base lines of the system shall be known by the same name on both sides of the base line unless the street or road shall be adequately designated by a prefix or suffix indicating a principle compass direction to denote the position of the street or road in relation to the base line (i.e., West Avenue 100, East Avenue 100, Northwest 200th Street, Southeast 200th Street). From and after the effective date of the ordinance codified in this article any public street, road or way established, shall be named in accordance with the following:

  • A. All streets, roads and ways running generally northerly and southerly to be known as "streets" or "roads."

  • B. All streets, roads and ways running generally easterly and westerly shall be known as "avenues" or "ways."

  • C. All streets, roads and ways running in a variable, curving or winding direction shall be known as "drives" or "lanes."

  • D. All cul-de-sacs or dead-ends, not a continuation of any of the above shall be known as "courts" or "places."

  • E. Major arterial routes through the county and/or cities thereof, may be known as "boulevards," "parkways," "freeways" or "throughways."

All streets, roads and ways shall be known by the same name for its entire length, and where a street, road or way shall change direction of 90 degrees or a greater angle, each direction shall be known by a different name; provided, that where such exists on the effective date of said ordinance, such may continue to exist provided there shall be no further extension of the street, road or way.

(Prior code § 23.13)

§ 15.08.080. Display of numbers.

The office, person or department designated to enforce, establish, continue, operate and maintain the numbering system shall give notice to the occupants or owners of land or buildings which are assigned or reassigned numbers under the system which notice shall contain the old number, the new number or the number reassigned to a particular building or parcel of land and the date on which the new number shall become effective. Within 10 days of the effective date of the notice of number assigned or reassigned, the occupants or owners of the property or buildings shall cause the number to be displayed upon the building or land in such a manner as to be visible from the street or road upon which the land or building fronts and shall remove or obscure from public view any old or previous number not in accordance with the system; provided, that in rural areas
