Preliminary plans for traffic calming Yerba Buena Avenue
from
Miraloma Drive
to
Plymouth Avenue
, and
Plymouth Avenue
from
Yerba Buena Avenue
to
Monterey Boulevard
.
Yerba Buena Avenue at Miraloma Drive (pdf).
This proposal includes a painted island in the middle of this Y shaped intersection. Currently, northwestbound Yerba Buena Avenue drivers can go further north on Miraloma Drive
or west continuing on
Yerba Buena Avenue
. However as these drivers approach the intersection, southbound drivers on
Miraloma Drive
do not know where northbound drivers are going. The painted island will force drivers to make a sharper left turn so that they would have to slow down to drive further west on
Yerba Buena Avenue. Because they slow down, southbound
Miraloma Drive
motorists will know which way the northwest bound drivers are going, and be better able to judge gaps to proceed onto southeast bound
Miraloma Drive
.
Yerba Buena Avenue at Hazelwood and Casitas Avenue (pdf)
This proposal will create two islands in the middle of the intersection. The large island will channelize vehicles through the intersection better and discourage any high speed cut through traffic from
Yerba Buena Avenue
onto Hazelwood or
Casitas Avenue
. Drivers from Hazelwood and Casitas Avenues will be channelized onto the areas of the intersection where they will be able to see
Yerba Buena Avenue
drivers better. To further help improve visibility and to slow down
Yerba Buena Avenue
traffic, a smaller island that is offset from the center will force drivers to zig-zag their way through the intersection. The smaller island will first be painted as a trial, but will eventually be converted to a mountable island in the future. This is called a traffic chicane. Drivers will need to slow down to maneuver through the chicane to avoid raised islands.
Yerba Buena Avenue at Brentwood Avenue (pdf)
This intersection is quite tight, so no raised islands are proposed here. We do propose installing a PAINTED island instead. This will create a chicane in the middle of the intersection, so drivers will have to maneuver their way through.
Yerba Buena Avenue at Plymouth Avenue (pdf)
An island at the north leg of this intersection is proposed to stop drivers cutting the corner from southbound
Yerba Buena Avenue
to
Plymouth Avenue
. The island will force drivers to make a sharper left turn; thus slowing them down. Some parking may be removed to accommodate bus turning.
Plymouth Avenue between Yerba Buena Avenue and Monterey Boulevard (pdf)
This plan would create several chokers and bulbouts that would force drivers to stay in the center of the road instead of using the travel and parking lanes as one big travel lane. The narrower roadway would slow drivers down as they would feel squeezed between the solid yellow line, the opposing traffic approaching and the parked cars/bulbouts along the curb. The bulbouts would also shadow the parking lane so that parked cars would be better protected from sideswipes by the bulbouts and force drivers back onto the center travel lanes of the roadway. Some parking may need to be removed and fronting property owners will have a say in where the chokers and bulbouts are placed.
