Residential 1. Yield 2. Low Density 3. Medium Density 4. High Density/Mixed Use 5. Boulevard Designed to carry low speeds and low volumes of vehicular traffic On-street parking varies and is generally dictated by level of density and need Density level is determined by lot size, total number of units, and length of block Pedestrian activity is expected, encouraged, and accommodated Bike lanes are typically not necessary due to low speed/volume, but are allowed
Residential Yield Street Yield Streets are 2-way and operate best where drivers are expected to travel at low speeds, allowing opposing traffic time and space necessary to negotiate (yield) conflicting movements Yield Streets have off-street parking provisions and a high demand for on-street parking (40 60% utilization or less). Yield Streets are can be found in historic neighborhoods with narrow streets, high density mix use neighborhoods. Yield Street parking on both sides functions most effectively at 24 28 feet (10-12 travel way and 7-8 parking). Yield streets parking on only one side can be as narrow as 16 feet, assuming that parking utilization is low enough for cars to safely yield and pass one another.

Residential Low Density Low density residential streets are two-way streets and operate best under low speeds and low volumes. On-street parking is typically not required due to low demand, but is allowed. Low density streets are typically found in both rural and suburban areas. Pedestrian activity is expected, encouraged, and to be accommodated. Low density is determined by number of lots/units per acre (i.e. single family homes on large lots, with four or fewer units per acre).
Residential Low Density Low density streets function most effectively at 20 22 feet (10-11 travel lanes). On-street parking can be accommodated at 20-22 feet, given the low demand and traffic volumes. 10-11 10-11
Residential Medium Density Medium density residential streets are twoway streets and operate best under low speeds and low volumes. On-street parking is allowed, unless demand is expected to be low, then parking on one-side should be considered. Medium density streets are typically found in both rural and suburban areas. Pedestrian activity is expected, encouraged, and to be accommodated. Medium density is determined by number of lots/units per acre.
Residential Medium Density Medium density streets function most effectively at 20 22 feet (10-11 travel lanes) On-street parking can be accommodated via yielding, or on one or both sides of street, depending on the demand. 10-11 10-11 7 10-11 10-11
Residential High Density/Mixed Use High density residential streets are compatible and sometimes integrated and with mixed uses. High density residential streets operate best under low speeds and low volumes, and often include traffic calming elements to moderate speed. High density streets are found in both urban and suburban areas.
CONTEXT SENSITIVE STREETS Residential High Density/Mixed Use On-street parking is typical on both sides, to accommodate high demand. Travel lanes to accommodate occasional local transit or freight vehicles. Bike lanes should be considered as traffic volumes increase. Pedestrian activity is expected, encouraged, and to be accommodated. 8 14 14 8
Boulevard Boulevards often function as high-speed thoroughfares, even though their adjacent land uses is primarily residential. Existing Boulevards typically have excess width, underutilized on-street parking, and too many travel lanes. Boulevards operate best under low to moderate speeds and often include traffic calming elements to moderate speed. Boulevards are found in both urban and suburban areas.
Boulevard Boulevards typically include curbside parking, dedicated bike lanes, curb extensions to provide direct access from homes to the center median. All of which serve to narrow the travel way and reinforce residential character and moderate speeds. Travel lanes to accommodate occasional local transit or freight vehicles. 8 5 4 11-12 8-10 11-12 4 5 8
Typical Cross-Section CS Street Types Residential Main/Commercial Vehicle Transit
Main Street/Commercial 1. Rural Main Street 2. Suburban Main Street/ Commercial 3. Urban Main Street Serves as center of civic, social, and commercial activity in all area types Design emphasis is focused on accommodating high volume of pedestrians Designed to carry low vehicle speeds and integrate bike and transit access Characterized by wide sidewalks, crossing treatments, and pedestrian oriented amenities Bike lanes are typically not necessary due to lower speed/volume street, but are as volumes and speeds increase
THOROUGHFARE A thoroughfare is a functional classification of roadway (arterial, collector, or local) that has a posted speed limit above 35mph. Thoroughfares typically serve moderate to high volumes of traffic and travel speeds and are typically primary transit and truck routes. Thoroughfare s support transit and non-motorized travel by providing both sidewalks and bicycle lanes. Thoroughfares generally serve both regional and local trips through a city. BOULEVARD - A boulevard is an arterial street with a posted speed limit of 35mph and under. Boulevards typically serve high volumes of traffic and moderate travel speeds and are typically transit and truck routes. Boulevards are intended to be walkable with a compatible speed limit (35mph and under) and encourage transit and non-motorized travel by providing pedestrian and bicycle facilities (i.e. sidewalks and bicycle lanes). Boulevards generally serve longer trips between major activity centers connecting destinations such as urban, employment, and housing. AVENUE An avenue is a collector street with a posted speed limit of 35mph and under. Avenues serve high volumes of traffic with low to moderate travel speeds. Avenues are intended to be walkable with a compatible speed limit (35mph and under) and encourage transit and non-motorized travel by providing pedestrian and bicycle facilities (i.e. sidewalks and bicycle lanes). Avenues serve short distance connections between activity centers. STREET A street is a local street with a posted speed limit of 35mph and under. Streets serve low to moderate volumes of traffic with low travel speeds. In general streets are intended to be walkable and support a mix of travel modes. Ideally, the posted speed should not exceed 25mph to accommodate the mixed modes. Streets serve short local trips and provide direct access to abutting properties.
