The standards for primary arterials are as follows:

A. Function. To expedite movement of traffic between major generators such as the central business district, outlying commercial areas or other cities, the college, and industrial areas; to collect and distribute traffic from freeways to less important streets or directly to traffic destinations; the predominant traffic will be through trips with minimum direct service to abutting land uses;

B. Right-of-Way. Eighty feet minimum;

C. Driving Lanes. Four to six lanes with from 24 feet to 36 feet of pavement width per side, 54 feet of total pavement width desirable; however, it may be reduced to 44 feet minimum when right-of-way is unavailable;

D. Design Standard. Concrete curbs and gutters and storm drainage to be provided. Curb cuts to vegetated LID facilities are permitted where feasible;

E. Median. Six-foot median desirable, with curbs on center optional. Medians shall include vegetated LID facilities where feasible. “Feasible” means the design criteria, limitations, and infeasibility criteria for each LID BMP as described in the Ecology Manual;

F. Sidewalks. Both sides with five-foot-wide walks minimum in residential areas; walks to be wider in commercial areas;

G. Access Conditions. Channelization at intersections or where critical to control turning movements; traffic signals at major intersections; pedestrian crosswalks at grade and parking restricted;

H. Planning Features. Desirable to bypass major shopping areas, parks, and residential developments; should never be adjacent to elementary schools or areas of high pedestrian traffic; primary arterials will seldom be closer than one mile apart. [Ord. 2017-03-009 § 2; Code 1980 at § 11.44.010].
