The city plans to install protected bike lanes on Valencia, with protected intersections, from 19th to Cesar Chavez, in the spring and summer of this year. "I love that it's protected," said advocate Magnus Barber, one of 400 people who attended an open house last night at City College's San Francisco Mission Campus, to learn about and comment on the plans. "Protected intersections make it difficult for cars to drive into the bike lanes."
They make it difficult for motorists to drive down bike lanes, and, if properly designed, they also force them to slow down as they turn.
"Mixing zones did not get the greatest reviews," said SFMTA's Kimberly Leung. The new designs, she explained, are at least partially inspired by the inexpensive, quick-build treatments in San Jose, which use a dual-radius turn. The first, outer radius is done with paint and bumps to audibly warn motorists if they're turning too quickly. The inner radius is created with plastic posts, which at least give the impression that if they don't adjust their turn they'll damage their cars (the idea is to eventually replace plastic posts with concrete curbs). Some at the meeting, after reviewing the schematics, thought the SFMTA designs still invite motorists to take turns at unsafe speeds. "The bollards are too far in--it doesn't force drivers to slow," said Kristof Didrickson, another supporter of safe infrastructure at the meeting.
Advocate Bruce Halperin and others pointed out that the one intersection that won't get protection in the designs is also the busiest, with the fastest traffic, and the one that needs it most: Valencia and Cesar Chavez. But Winnie Lee, an engineer with SFMTA, said recently built transit bus bulbs would have to be jack-hammered out to redo that intersection, which would end up costing over $1 million. She added that's something they want to do in a future stage of the project. For now, they will add more paint and posts and continue to use mixing zones, as seen in the diagram below:
Also saved for a future project: the missing middle, 15th to 19th Street. Engineers are still working on designs for this stretch, which has wider sidewalks, overhead Muni wires, and tighter dimensions. Adding protected bike lanes on this part would require removing parking.
At last month's opening of a 'car-free' Market Street, SFMTA Chair Malcolm Heinicke suggested that Valencia could also be a car-free space. Maybe this four-block stretch is the right place to give that a try. Or rather than car-free, maybe an "access only" arrangement makes sense here, where pedestrians and cyclists are given priority, but motor-vehicles can still access storefronts and driveways from intersecting streets, but then are diverted back off at the next block.
This arrangement maintains delivery access and drop-offs, and leaves plenty of room for biking and walking. Think of it as a permanent, four-block, modified 'Sunday Streets.'
Meanwhile, parishioners from St. Mark Institutional Baptist Church, a little over 200 feet from the intersection with 19th, were concerned that protected bike lanes complicate things for elderly people trying to get to church. "What about people who have a right to worship?" said Naj Daniels, seen below on the left with Bertha Butler, who drives or takes the bus to services from her home in the Fillmore.
