A. Low Density. A low density street provides minimal access to rural portions of the city where tracts of land are typically five acres or larger in size. Traffic density should be in the range of 50 to 100 vehicles per day, and speeds are expected to be slow. Maintenance will be low priority for city road crews. A low density road standard is generally acceptable only for subdivisions that meet the requirements of the Matanuska-Susitna Borough waiver process. Subsequent subdivisions or development may require upgrade of low density streets to a minimum of local/residential standards.

B. Local/Residential Streets. A local/residential street provides movement of local traffic from individual properties to collector and arterial streets. Lower traffic speeds and volumes of less than 200 annual average daily traffic (AADT) are expected. Residential streets are typical subdivision, subdivision feeder streets, and cul-de-sacs. Direct access to adjacent private property with individual driveways is common and acceptable.

C. Commercial Streets. Commercial streets provide access to and movement through business, industrial, retail and other commercial areas of the city. Traffic volumes are expected to be high, and speed limits should not exceed 35 miles per hour. On-street parking may be accommodated and intensive traffic control achieved through the use of signs, signalization and, where appropriate, one-way traffic.

D. Minor Collector Streets. A minor collector street provides for movement from subdivisions and residential streets to major collector roads, arterial roads and highways. Minor collectors may also carry traffic from one neighborhood to another, or from one neighborhood to other areas of the community. Traffic volumes range from under 400 AADT to more than 2,000 AADT. Although design speeds on flat terrain are 50 miles per hour, most collector traffic speeds are generally expected to be 25 to 35 miles per hour. Direct access to private property is acceptable when other access is not available, or should be limited to intervals that do not inhibit traffic flow and public safety.

E. Major Collector Streets. Major collector streets provide for intercity movement and access to arterial and interstate roads, as well as connecting traffic to and from residential areas. Traffic volumes will be high and driving speeds should be at least 35 miles per hour, except in congested urban areas. Access should be limited to other collector streets and commercial streets. Direct access from low density and local/residential streets should be discouraged. (Prior code § 14.10.030)
