10.26.010 Criteria.

The following criteria in this chapter shall be used for purposes of classifying streets within the city. (Res. 130, 1972)

10.26.020 Major arterials – Traffic service provided.

Major arterials provide for movement across and between large subparts of an urban region and serve predominantly “through” trips with minimum direct service to abutting land uses. (Res. 130, 1972)

10.26.030 Major arterials – Grouping of traffic generators.

Major arterial service is required by medium-to-large central business districts, most municipal airports, large shopping centers, large colleges and universities, large industrial plants, major governmental centers, large hospitals, important secondary business districts, major rail and seaport terminals and similar land uses which comprise the top layer of the hierarchy of trip generators. (Res. 130, 1972)

10.26.040 Major arterials – Spacing.

Major arterials will seldom be closer than one mile apart in even the most densely developed urban regions. In practice, it is expected that for most urban areas in Washington spacing of major arterials will be wider. Moreover, spacing will vary within any given urban area with major arterials being closest together in the vicinity of the central business district and becoming increasingly farther apart toward the suburban, rural boundary. (Res. 130, 1972)

10.26.050 Major arterials – Route continuity.

Major arterials shall form a closed, interconnected system linking together major traffic generators in urban areas. Stub end arterials are not normally classified as major arterials. (Res. 130, 1972)

10.26.060 Secondary arterials – Traffic service provided.

Secondary arterials provide for movement within the large subparts proscribed by major arterials. Secondary arterials may also serve “through traffic” but provide very much more direct service to abutting land uses than do major arterials. (Res. 130, 1972)

10.26.070 Secondary arterials – Grouping of traffic generators.

Secondary arterial service is required by small central business districts and traffic generators as listed above for major arterials except that such generators will be smaller, plus high schools and some grade schools, strip commercial development, parks, and low-use intensity recreational areas, warehousing areas, and similar land uses which comprise the middle layer of the trip generator hierarchy. (Res. 130, 1972)

10.26.080 Secondary arterials – Spacing.

Secondary arterial streets will seldom be closer than one-half mile from another secondary, or major, arterial street. In practice, it is expected that for most urban areas in the state of Washington the spacing of arterial streets will be wider. Moreover, spacing will vary within any given urban area with secondary arterials being closest together in the vicinity of the central business district and becoming increasingly farther apart toward the suburban, rural boundary. (Res. 130, 1972)

10.26.090 Secondary arterials – Route continuity.

Secondary arterials shall, wherever possible, be long, continuous streets with direct rather than meandering alignments. (Res. 130, 1972)

10.26.100 Collector arterials – Traffic service provided.

Collector arterials provide for movement within the smaller areas, which are often definable neighborhoods, and may be bounded by higher class arterials. Collector arterials serve very little “through” traffic, but serve a high proportion of local traffic requiring direct access to abutting land uses. (Res. 130, 1972)

10.26.110 Collector arterials – Grouping of traffic generators.

Collector arterial service is required for the majority of the nonresidential land uses which generate measurably important traffic volumes and which are not served by major or secondary arterials. (Res. 130, 1972)

10.26.120 Collector arterials – Spacing.

Collector arterials will seldom be closer than one-fourth mile from any other arterial street. In practice, it is expected that for most urban areas in the state the spacing of arterial streets will be wider. Moreover, spacing will vary within any given urban area with collector arterials being closest together in the vicinity of the central business district and becoming increasingly farther apart toward the suburban, rural boundary. (Res. 130, 1972)

10.26.130 Collector arterials – Route continuity.

Collector arterials need not be particularly long or continuous since this would tend to attract through trips in unduly high proportions. (Res. 130, 1972)

10.26.140 Secondary arterials – Designated.

Based on the above criteria and the city engineer’s recommendation the following streets shall be classified as secondary arterials:

“B” Street from 15th Street to 32nd Street;

27th Street from “B” Street to Index Street;

Index Street from 27th to the Bonneville Power Storage Facilities. (Res. 130, 1972)

10.26.150 Collector arterials – Designated.

“C” Street from 6th to the west city limits shall be classified as a collector arterial. (Res. 130, 1972)
