Commercial alleys, though often thought of as dirty or unsafe, can be designed to play an integral role in a downtown street network and improve the pedestrian realm in and around commercial areas. The design of commercial alleys should strive to balance their necessary utilitarian features with their place making potential.
Recommendations
Intersections between alleys and side walks have the potential to obstruct visibility for vehicles (if permitted) and passing pedestrians. Raise the intersection to the sidewalk grade and add rumble strips to mitigate these visibility issues. Warning signs should be provided to warn pedestrians of encroaching traffic.1
Freight may use green alleys for loading and unloading, which reduces double-parking on neighborhood streets.
1Where access for vehicles is prohibited or minimal, commercial alleys may be constructed using low-impact pavement materials, such as pervious or modular paving.
2Bicycle traffic may use commercial alleys. Similar regulations to those of shared space should apply.
Commercial alleys can be restricted for traffic during non-delivery hours for outdoor seating or other uses.
Where vehicle access is permitted, alleys should be maintained to allow easy access by trucks and other freight vehicles. Bollards and other street furniture should be designed to minimize conflicts with freight movements. In some cases, freight may be conveyed using hand trucks or small vehicles. In these cases, careful attention should be paid to the location of curbs and the access from loading zones to entrances to ensure smooth deliveries.

Alley redesign can feature pavers for the traveled way, parking restrictions, and additional public space.
