Local Street Sub-Classifications local streets are divided into several sub-classifica- tions: · Alleys · Access Lanes I · Low Volume Residential Streets · Medium-Volume Residential Streets · Commercial-Industrial Streets Alleys: Alleys are streets that provide secondary access to residential properties where street front- ages are narrow, where the street is designed with a narrow width to provide limited on-street parking, or where alley access development is desired to increase residential densities. Access Lanes: These streets are designed for primary access to a limited number of properties. On this street type, the residential environment is dominant and traffic is subservient. Access Lanes can be constructed as cu I-de-sacs, loop streets, or short streets connecting two other streets. Access lanes generally serve 25 or fewer homes and traffic volumes are less than 250 Average Daily Traffic (ADT). Low-Volume Residential Streets: These streets are designed for primary access to individual residential property as well as access to adjacent streets. As with the Access Lane, the residential environment is dominant. Traffic volumes are relatively low (250- 750 ADT). Medium-Volume Residential Streets: These streets are designed for primary access to individual residential property and to connect streets of lower and higher function and access the major street network. These streets are designed to accommo- date higher traffic volumes (750-1,500 ADT). ' Commercial/Industrial Streets: These streets are designed for primary access to commercial and industrial properties and to connect to the major street network. They are designed to accommodate higher traffic volumes and freight. 36 Local Street Design Standards The typical design elements found in a local street right~of-way are: sidewalk and planting strip areas, parkmg lanes, vehicle traffic lanes, parking lanes, drainage and curbs, planting strips, sidewalks, utilities, street lighting, and occasionally a center median. The standards in paragraphs A-M below apply to both new and existing unimproved local streets, unless otherwise stated. A. Vehic;le La nee 1) Two 101 vehicle traffic lanes are required on local residential streets when traffic volumes are expected to exceed 750 vehicles per day. 2) On local residential streets with traffic vol- umes less than 750 vehicles per day, a single 141 traffic lane may be permitted for both directions of vehicular travel. The single traffic lane is intended to create a "queuing street", such that when opposing vehicles meet, one of the vehicles must yield by pulling into a vacant portion of the adjacent parking lane. This queuing effect has been found to be an effective and safe method to reduce speeds and non-local traffic. 3) Two 121 wide vehicle traffic lanes are re- quired on local commercial and industrial streets. 4) In special circumstances, such as where a local street intersects with a collector or arterial street, additional width may be required for safe turning movements. 6. MetJiane 1) Center medians are a design option for Low- Volume and Medium-Volume Residential Streets, but the street design must ensure the minimum 141 clear lane needed for fire apparatus. 2) Medians shall be landscaped with groundcover, trees, and shrubs less than 31 in height.
