Tonight , city officials with LADOT and City Planning will present the environmental documents for five Bike Plan projects in West Los Angeles. Highlighting the list of projects is a proposal by the Los Angeles County Bicycle Coalition (LACBC) to restripe 1.6 miles of Westwood Boulevard between National Boulevard and Santa Monica Avenue to create a “floating” bike lane in each direction. LADOT has said they would back such a plan if there were community support.
Basically, if a floating bike lane were installed, the city paint what would at first glance appear to be multiple bike lanes. During different periods of the day, the street configuration would change. For example, during off-peak hours there would be car parking along each curb, then a bike lane, then two mixed use travel lanes and a turn lane, then another bike lane, parking, and the alternate curb. At rush hour, there would be two lanes in one direction and one in the other (it changes pending which rush hour) with a turn lane and bike lanes hugging the curb.
For more information on how floating bike lanes work, read this case study from San Francisco . It states that the design, while not perfect, generally works.
While not perfect, with its slightly confusing, unorthodox design, it successfully accommodates cyclists, part-time on-street parking, and motorists needing additional capacity during peak hours. It does so with minimal signs, leading one to conclude that while the design is unorthodox, it uses fairly predictable road-user behavior to its advantage. Cyclists naturally tend to stay to the right, and motorists will use a space even if it is not clearly for their use if traffic congestion reaches certain levels and the space is reasonably accommodating.
Following 150 riders attending the Ride Westwood! ride and rally the previous Saturday, the LACBC’s Eric Bruins attended the Westside Neighborhood Council meeting on Valentine’s Day to press for the “floating bike lanes.” In advance of his meeting, some on the Council circulated a letter deriding the plan, encouraging attendance and even stating that “even the local cyclists find the proposal unworkable.” More of the letter is available at Biking in L.A. 
Despite the email blast, Rancho Park Online reported  that most of the people in attendance that spoke were in favor of the proposed changes. Conversely, most of those on the Neighborhood Council were skeptical.
Several of the Neighborhood Council members are also members of Neighbors for Smart Rail, which has taken its case against the Expo Line and supported lawsuits alleging that city environmental studies for the Expo Bike Path were flawed.
Against this backdrop, the city holds a community meeting on the Bike Plan tonight at 11214 West Exposition Boulevard at 6:00 p.m.  In January, it announced that it would abandon the EIR process for 39.5 miles of bike lanes that will cause a change in existing traffic patterns. Because of a change in state law, a full Environmental Impact Report isn’t necessary for these bicycle projects provided some study and outreach is completed.
