When San Francisco streets are opened up to people for Sunday Streets, the influx of foot traffic brings a host of health and economic benefits to the city’s neighborhoods, according to findings presented by Dr. Susan Zieff, a professor of kinesiology at SF State University, at a Board of Supervisors committee hearing yesterday.
Zieff and her team surveyed 600 Sunday Streets participants at events 2010 and 2011, collecting data that makes a strong case for investing in open streets events. One of the data points we reported in late 2011, for instance, is that every dollar spent on running Sunday Streets yields an estimated savings of $2.32 in medical costs.
The studies “have been really invaluable to us,” said Tom Radulovich, executive director of Livable City, which organizes Sunday Streets with help from city agencies.
The top reason people come to Sunday Streets, said Zieff, is to enjoy the city’s streets in a way that’s impossible at nearly any other time, when the space is primarily reserved for traffic and parking.
“Over and over again, people talk about being able to walk down the middle of the street with their families, do physical activity in a safe environment, not to worry about vehicle traffic, and generally be around people who are having a good time,” said Zieff.
In Zieff’s survey, 51 percent of participants reported coming from outside the neighborhood, and the average participant traveled 3.25 miles, round trip, to the event. Among those who had attended Sunday Streets more than once, 25 percent reported an overall increase in physical activity since they began participating in the events. And, Zieff noted, the ethnic demographics at Sunday Streets are generally representative of the city as a whole, meaning the events appear to be effective at increasing physical activity among African-American and Latino residents, who tend to suffer the highest rates of cardiovascular disease.
