In a recent op-ed for Next City, Erin Caldwell emphasizes the importance of diverse businesses in neighborhoods and their impact on walkability. She argues that a neighborhood filled with non-useful businesses is just as bad for walkability as one lacking in businesses altogether. Cities can shape development through zoning codes to encourage the presence of useful businesses, such as those that fulfill essential needs. By allowing useful businesses in residential or mixed-use areas and restricting non-useful businesses to industrial or commercial districts, cities can create more walkable and vibrant neighborhoods.
Caldwell suggests creating objective measures to determine the usefulness of businesses, such as the number of in-person transactions or the presence of amenities like public restrooms and seating, could help enforce these new zoning laws. Additionally, she proposes accessory commercial units, which are business spaces attached to residential units, as a way to enrich mixed-use communities.
According to Caldwell, retail establishments play a significant role in community building. Accessible retail and recreation centers serve as ‘town squares’ where neighbors can gather and interact, fostering a sense of community. By creating spaces that encourage repeat visits from residents, businesses can help strengthen relationships between neighbors and businesses, contributing to the overall fabric of the community.
