Street Design Manual

3.2.4 A - Avenue 4-Lane, Parallel Parking The Four-lane Avenue provides a good level of mobility for all street users, and is a preferred street type for urban contexts where transit vehicles and cyclists are part of the traffic mix. Medians provide refuge for crossing pedestrians. For more pedestrian-intensive contexts, the width of the Streetscape may be expanded. Curb parking provides vehicular access to adjoining land uses and buffers pedestrians from moving traffic. Sidewalks are required on both sides of the street. Four-lane Avenues are conducive to use of GSI practices including street trees in grated wells, curbside bioretention and/or bioretention in curb extensions/bump-outs, and bioretention in medians. Permeable pavement may be desirable within on-street parking areas and for sidewalks.
