1. Principal Arterial. This is the basic element of the City’s road system. All other functional classifications supplement the principal arterial network. It carries large volumes of traffic over long distances. Access is generally limited to intersections with other arterials and collectors. Signalized intersection spacing is regulated. Direct land access is minimal and managed. Spacing is typically 2 to 5 miles.

2. Minor Arterial. This street collects and distributes traffic from principal arterials to streets of lower classifications and may allow traffic to access destinations directly. Minor arterials provide for movement within City subareas whose boundaries are largely defined by principal arterial roadways. Minor arterials serve through traffic and provide direct access to large commercial, industrial, office, and multi-family development but generally do not provide access to single-family residential properties. Spacing is typically less than 2 miles.

3. Collector. This type of street provides for land access and traffic circulation within and between residential neighborhoods and commercial and industrial areas. The collector street also collects traffic from local streets and channels it into the arterial system. Direct access to adjacent land uses, however, is still subordinate to traffic movement. Access to abutting properties is controlled through driveway spacing and pavement markings. Typically, collectors are not continuous for any great length, nor do they form a connected network by themselves. Spacing is typically less than 2 miles.

4. Industrial. An industrial street provides land access and traffic circulation within industrial and manufacturing areas. An industrial street is designed to meet the needs of significant volumes of large vehicles including trucks, trailers, and delivery vehicles. There are three classifications of industrial streets based on the anticipated traffic volume. These include principal, secondary, and local. Typically, parking is not allowed, except for loading zones necessary to accommodate delivery needs.

1. Design Criteria. The design criteria shown in Table 11.80.040.C-1 are adopted as a portion of the City’s standard plans and specifications. These criteria are intended for normal conditions. The Director may require higher standards for unusual site conditions; these may include, but are not limited to topographic features or sight distance constraints. Additionally, higher standards or limitations may be required by adopted plans including but not limited to those listed below. These higher standards may include, but are not limited to, additional right of way or easements and specific design standards to enhance safety, provide design solutions responding to unique neighborhood characteristics, and facilitate maintenance. The following adopted plans have specific requirements and guidelines:

2. Industrial Areas. Streets completely within and through industrially zoned areas providing access to or through individual parcels or buildings will be classified as either public or private. All public industrial streets must comply with the industrial street standards of Table 11.80.040.C-1 and all other applicable standards. All private industrial streets shall comply with the requirements of Section 11.80.050. Streets with industrial zoning on one side will be constructed to industrial street structural sections and will have sidewalks on both sides.

3. Private Streets. Private streets are not required to comply with the design criteria shown in Table 11.80.040.C-1. All private streets shall comply with the requirements of Section 11.80.050.
