Landscaped Buffer Strip
ELM-LBS-30 Landscaped Buffer Strip
Working assessment: this pattern’s status reflects a preliminary Commonway System judgment call, pending final review.
#Why this pattern exists
A planted buffer between moving traffic and pedestrians provides psychological and physical separation beyond what a curb alone offers, while also creating usable space for trees, snow storage, and stormwater treatment that a fully paved streetscape does not accommodate. This pattern exists to document the width and design considerations that make this zone function well.
#Key considerations
- Width should be sufficient to support meaningful tree growth and planting; a strip too narrow limits both plant health and its buffering effect
- Should account for a maintenance plan, since an unmaintained buffer can become an eyesore or a weed-choked liability rather than an asset
- In snow climates, the strip may also serve as snow storage space, which should be planned for in plant and material selection
