• Special Area Collectors are intended to link traffic from Special Area Local Streets, Special Area
Neighborhood Routes, and some Special Area Commercial Streets to Arterials. Posted speeds
are low to moderate. A moderate degree of non-transit-oriented development traffic would be
acceptable for these facilities.

The design of a Special Area Collector provides multimodal access to the Arterial system, station
area employment and high density residential areas while discouraging traffic infiltration on lo-
cal streets. In addition to autos, these facilities accommodate primary and secondary bus lines,
bike lanes and sidewalks separated from the street by a landscape strip. Based on an engi-
neering analysis, left turn lanes in medium and low density residential areas may be generally
provided at intersections with Arterials.

Developments which are oriented to Special Area Collectors are generally employment-based or
multi-family residential. Single-family residential developments that abut a Special Area Collec-
tor are typically oriented away from road.

• Special Area Neighborhood Routes serve both a traffic collection and distribution function and
provide access to adjacent properties. These facilities are intended to have less volume and less
through-traffic than Special Area Collectors. Posted speeds are low and a limited amount of non-
transit-oriented development traffic is acceptable for these facilities. New Special Area Neighbor-
hood Routes that are not in this plan may be established via the land development process.

The design of Special Area Neighborhood Routes emphasizes neighborhood orientation by ac-
commodating on-street parking, transit service and bicycles in a relatively narrow paved width
which includes the use of traffic calming measures. Exclusive turn lanes are not appropriate for ADOPTED TEXT
these facilities unless needed for safety at intersections with Arterials.

• Special Area Neighborhood Routes primarily serve residential land-uses. Development which
includes small to medium scale mixed uses is also appropriate.

• Special Area Commercial Streets serve local access and service needs associated with urban
high density residential, mixed use and employment-oriented land uses. These roads are not
intended to serve through-trips but may have higher traffic volumes than Special Area Neighbor-
hood Routes. The street may not exceed two travel lanes in each direction. Speeds should be
low. New Special Area Commercial Streets that are not in this plan may be established via the
land development process.

The design of Special Area Commercial Streets reflects intensive localized urban use by all
modes. The road must accommodate autos, trucks, buses and bicycles while also providing
transit stop amenities and frequent opportunities for pedestrian crossings. Sidewalks are wide
and have tree wells to encourage walking.

• Special Area Local Streets provide direct property access. They are not intended to serve
through traffic. Posted travel speeds are generally low. The design of Special Area Local Streets
reflects the residential neighborhood function by accommodating on-street parking on a narrow
paved width which can include traffic calming measures to slow down traffic. Special Area Local
Streets should serve only low to medium density residential districts. New Special Area Local
Streets that are not in this plan may be established via the land development process.
