Excessive traffic speed and traffic volumes are two major concerns in the St. Francis Wood neighborhood,
which is a master-planned community designed by pioneering landscape architect Frederick Law Olmsted.
The major spine of this neighborhood, Santa Clara Avenue, is designated as a secondary arterial road in
the San Francisco General Plan because its easterly boundary is the I-280 on- and off-ramps at Monterey Boulevard.
This street and several other streets are used by commuters as major access to and from the freeway.
CHS was the lead design firm for this project. CHS also led public presentations and consensus-building
efforts with community stakeholders. With the support of 50 neighborhood residents, CHS led an extensive
license plate survey and verified that the neighborhood’s concerns were valid. CHS developed a toolbook
to assist the neighborhood in understanding the pros, cons, and cost implications of various traffic calming
strategies. CHS also worked closely with the taskforce established by the St Francis Wood Homeowners Association,
and staff from the Department of Parking and Traffic (DPT) on the screening and selection of traffic calming strategies.
We recommended both short-term and long-term strategies, including: a trial roundabout, speed humps,
and signage and striping changes to reduce speed, as well as signal timing changes to reduce traffic
volumes and make pedestrian crossings safer.
DPT agreed to reduce the traffic speed limit along a portion of Yerba Buena Street with proper signage,
to install speed humps at several locations, and potentially modify signal timing to reduce the throughput
of traffic volumes into and out of the neighborhood. Some of the recommendations have already been implemented.
