West Lake Sammamish Parkway is far and away the most dangerous road to ride a bicycle in King County because it has inadequate lane width to travel northbound with traffic. Current design calls for a minimum of 12' vehicle travel lanes for roadways with no shoulder and suggests a minimum of 11' motor vehicle lanes with 5' shoulders for bike travel. The WLSP northbound vehicle lane is only 10' wide prompting cyclists intimidated by honking motorists to stay of the public road or illegally travel against the flow of traffic on the west shoulder. This results in confusion on which side to pass among pedestrians and cyclists traveling both directions on the same 10' shoulder and significantly increases the chance for head-on collisions with vehicles. A 1974 study commissioned by Caltrans found wrong way cycling responsible for 2.5 times the number of collisions involving motorists exiting from driveways. According to a WS DOT study of car-bicycle accidents between 1988 and 1993, 8% of bicycle fatalities result from wrong-way riding, and “The number of bicycle collisions in which a bicyclist was riding the wrong way is two and one-half times the number of collisions in which a bicyclist was struck from behind by a motor vehicle.” The following letter from Friends member Phil Miller validates the studies above with a study done on WLSP and supports the plans to add a northbound bike lane to the parkway.

West Lake Sammamish Parkway Input

Dear friends and neighbors,

I am writing both in support of the City's proposed improvements to West Lake Sammamish Parkway and to provide some background information requested by Mr. Cole and Ms. McCormick at the recent Grass Lawn Neighborhood Open House. I believe that the proposed design both rectifies a glaring problem on the parkway for bicyclists and pedestrians while addressing in an efficient manner the concerns of local residents. 

Bicycle and Pedestrian Collisions with Motor Vehicles in King County

As many of you know, from 1987 through 1999 I was employed as a Senior Transportation Planner for the King County Department of Transportation during which time I served as Program Manager for the County's Non-Motorized Transportation (RoadShare) Program.  During this time, I collaborated with the Harborview Injury Prevention and Research Center (Dr. Fred Rivara and Dr. Abe Bergman) on a number of projects, including a comprehensive study of all pedestrian and bicycle collisions with motor vehicles during the 1985-1990 time frame. This study involved examination of original filed collision reports on all King County and State surface highways during the study period.  During a portion of this time, WLSP was a state highway and was thus included in the study.

One of the notable findings of the report was that fully one third (33%) of ALL bicycle collisions with automobiles and trucks involved wrong-way cycling as either a primary or contributing factor.  Wrong way cycling is one of of over twenty factors considered, yet represented 1/3 of all accidents.  This is a very significant and relevant statistic in that the current configuration of WLSP essentially mandates counter-flow (wrong way) cycling on the Parkway.  This characteristic of the parkway has remained unchanged since installation of the 2 way lane in the late 1970's.

While the changing jurisdictional character of WLSP during the study period made calculations of accident rates difficult, WLSP was far and away the single road with the greatest number of recorded collisions during the study period.  ALL collisions involved counter flow cycling in the designated bike facility.  It is truly rare that the negative impacts of a design are so clearly demonstrated.  Almost all of the collisions involved a driver entering WLSP from a west side access road or driveway failing to scan for unanticipated northbound bike traffic before pulling into the path of a bicyclist. All collisions resulted in transportable injury to the bicyclist.

Standards & Liability

The proposed project finally would return WLSP to a configuration consistent with the design standards and guidelines adopted by the American Association of State Highway and Transportation Officials (AASHTO) and the Washington State Department of Transportation.  Neither of these organizations can be claimed to be held hostage by bicycle advocates -especially so in the case of AASHTO.  AASHTO's guidelines are the basis not just for bicycle facility design in the United States, but for all aspects of highway design.  AASHTO for years has strongly discouraged the practice of two-way parallel facilities for bicyclists - for the same reasons so graphically illustrated by the King County/Harborview Collision Study. It is one thing to maintain a facility designed poorly but in good faith as it was built - but to rebuild the road and then knowlingly fail to apply the universally accepted design standard  invites what will seem to you to be a never-ending series of claims and lawsuits against the City, and with good reason.  The City has a ministerial responsibility to apply sound engineering and design judgement, particularly if it is aware of a deficiency in the design of a facility under its jurisdiction.  The City has heard for years from bicyclists regarding the unsafe conditions on WLSP.  I believe that the City has heard these concerns and made an excellent effort to rectify the problem.  Making a change at this late date that would leave the status quo intact is a mistake for which the City will likely pay dearly for years to come. 

Property Rights or Public Right of Way

This project is about the public's use of the public right of way - while some of the adjacent waterfront property owners have concerns about the project, those concerns which are legitimate have been addressed.  Driveways will be modified to improve vertical sight distance, even if the responsibility for creating the problem likely rests more with the property owners than with the City.  Parking will be preserved to a significant degree, although as we have all learned in the RV ordinance, parking in front of one's home is not a limitless right.

Some of the waterfront owners would have you believe that creating a bikelane on the east (northbound) side of WLSP creates a hazard to traffic - obviously the opposite is the case.  If the northbound shoulder is paved but not reserved for a bikelane, parked cars will block the sightlines of drivers exiting homes far worse than is the case today.  At some point, we have to recognize the value of WLSP to the whole community, and let public projects reflect public values and not the strongarming of those who think they can create their own private retreat in defiance of the needs of the rest of us.  Building the bikelane and pathways only moves pavement on average TWO FEET to the east - more than enough is left for residents to park their speedboats and Navigators on the remaining shoulder.  I don't even mind them parking these vehicles on the public right of way, so long as the safety and mobility needs of the citizens of Redmond are addressed first.

The proposed project is well designed and best meets the needs of the whole community - let's get going and do the job.
