Official Streets & Highways Plan
The major streets in the Municipality are classified in the Official Streets and Highways Plan (OS&HP) as collectors (class I), minor arterials (class II), major arterials (class III), expressways (class IV), or freeways (class V.) The OS&HP is available online, and hardcopies can be obtained through the Transportation Planning Division (AMATS) in the Planning Department.
In the B-1A, B-1B, and B-3 districts, arterial landscaping must be planted along classified streets. In the I-1 district, visual enhancement landscaping must be planted along classified streets. Buffer landscaping must be provided for cluster housing and Planned Unit Developments. Additional Information: Landscaping Standards.

AMC 21.45.110.B allows fences up to 8 feet in height on some through lots abutting classified streets (otherwise the height restriction is 4 feet.)
Hospitals, correctional facilities, churches, cemeteries, high schools, snow disposal sites, gas stations, storage yards, mini-storage facilities, junkyards, drive-in banks, and some hotels and apartment buildings must have access to a classified street.
