+
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.
