Street Design Manual

Section 3.2.3 - B Avenue 3-Lane, Parallel Parking A Three-lane Avenue with on-street parking and bike lanes offers significant flexibility. The cross-section is ideal to use in a context featuring residential uses with some ground floor commercial uses or in areas with a mixture of uses. This type provides significant multimodal accessibility and mobility, yet maintains lower speeds and an appealing character, particularly when the center lane includes some landscaped median features. Sidewalks are required on both sides of the street. Use of GSI practices may be desirable with Three-lane Avenues, including permeable pavement for sidewalks and on-street parking areas and bioretention within medians. In addition, Three-lane Avenues also are conducive to use of curbside bioretention and bioretention in curb extensions/bump-outs, stormwater planter boxes, and stormwater street trees (also referred to as tree boxes) as alternatives to tree grates.
