Update: City Council selects to remove parking and lanes on Duane Avenue to make room for buffered bike lanes.
Tonight, the city council for Sunnyvale, California will discuss a city staff proposal to add bike lanes to a one mile segment of Duane Avenue between Stewart Drive and Fair Oaks Avenue. Space for the lanes will be made by removing some street parking and reducing the stroad from four lanes down to three.
Currently, Duane Avenue is 72 feet of two parking lanes and four 12-foot-wide travel lanes, as shown below. (And please never mind the backwards parking on the right hand side – mistake on my part!)
City council directed the transportation department to figure out a way to add bike lanes to this road. They came up with three alternatives that involve either removing lanes, removing parking, or a little of both. The staff recommends Alternative 1, which removes lanes while preserving most street parking.
Sunnyvale Transportation staff reports 5,500 vehicles per day travel down Duane Avenue, with an 85th percentile speed of 39 to 43 MPH, which is well above the posted 35 MPH speed limit. 30 total vehicle collisions, 5 bicycle involved collisions, and 1 pedestrian-involved collision have occurred in the last five years (and kudos to the city of Sunnyvale for calling these collisions instead of “accidents” in their reports).
Currently, the existing four lanes on Duane Avenue handle 5,500 vehicles per day westbound and 4,500 vehicles per day eastbound; road engineering standards suggest a single lane of traffic can handle 10,000 vehicles per day at an acceptable level of service, so Duane is clearly overbuilt. People use about a third of the available street parking on Duane Avenue. Under Alternative 1, which retains street parking on both sides of Duane Avenue, some parking would be removed at intersections in order to improve visibility of bikes in the bike lanes.
You can view the full staff report here. The Sunnyvale City Council meets 7 PM tonight, Tuesday, September 10, 2013 in council chambers at City Hall, 456 West Olive Avenue, Sunnyvale, CA. Each speaker is given three minutes to speak on a topic. Duane Avenue is the first item of general business after the consent calendar, so be on time.
