Minor arterial roads are automobile oriented roads intended to move high vehicle traffic volumes and are typically four lanes. Pedestrian and bicyclist accommodations are sometimes expected. Other common characteristics include:
*Boulevards are often wide but must accommodate sidewalks on both sides, street trees and splash pads
*May include narrow medians, but runoff is typically directed away from them to road sides
===Typical LID opportunities===
'''Within the roadway:'''
*Dedicated parking lanes or parking lay-bys can be converted to permeable pavers. The permeable parking lane can be designed to accept only the rainfall that falls on it or it can take runoff from up to two additional lanes.
'''Within the boulevard:'''
*Attractive bioretention planters and permeable paver sidewalks are appropriate for high density areas and where business districts expect an enhanced or signature streetscape.
*Street trees can be supported with LID options by providing root volume space in bioretention practices or with sidewalk support systems. Permeable sidewalks allow air and moisture to reach tree roots which in turn reduces sidewalk buckling from roots pushing through the surface.
