==Residential collector road==
The function of these streets is to act as connectors between
residential neighborhoods and other collectors and arterials.
The character of these streets can vary widely from completely
residential to pockets of commercial or mixed use landuses.
Other characteristics include:
• Moderate to high traffic volumes, average daily traffic
1500 to 3000 vehicles
• Street parking is atypical unless there are adjacent
mixed uses.
• Often have multi-modal use, transit, pedestrian, and
cyclists
• Institutions such as schools, recreational facilities, and
churches are often located along collectors
Typical LID opportunities
Within the roadway:
• Permeable pavement should be avoided for high traffic
travel lanes, but they are an option for parking lanes
and sidewalk. Pervious concrete or porous asphalt are
options for bike lanes.
• Perforated pipes are suitable for collectors with very
limited space and particularly where there is no
routine landscaping maintenance. However, adequate
pretreatment such as grass swales, extended sump
catchbasins, or prefabricated units must be provided.
• Curb extension bioretention is not a common practice
for collectors, but they can be used in some cases to
reduce pedestrian crossing distances at intersections
Within the boulevard:
• Collectors with few driveway access points and
continuous stretches of open boulevard space are good
candidates for bioswales
• Institutional uses along collectors offer opportunities for
innovative LID solutions. Runoff can be treated within
adjacent park space or on school properties where
agreements have been made with school boards. These
areas are also good opportunities for LID showcases or
demonstrations.
