(1) Tukwila Bicycle Routes and Sidewalk Segments Design Report; Jim Haggerton, Mayor Background The City hired Perteet, Inc. in April 2009 to develop a design report for bicycle friendly routes and missing sidewalk segments identified in the Walk and Roll Non Motorized Transportation Plan. Included in the Design Report are the following: (1) An analysis of at least two improvement options for each bicycle and pedestrian project; (2) Preliminary design work and cost estimates for each of the 29 bicycle projects and 12 sidewalk projects; (3) A screening analysis of the relative construction difficulty of the projects in the Report. The information contained in the Design Report identifies the cost and level of difficulty to construct each bicycle and pedestrian project, and includes a recommendation on a short-term and a Tong -term improvement on some bicycle routes. The information on feasibility, combined with the preliminary design work developed in the Design Report, provides needed information to budget for projects within the Capital Improvement Program (CIP) and to apply for grants. Analysis A spreadsheet is attached that includes a short description of each project in the Design Report, a cost estimate, and the level of difficulty involved in construction. The projects are classified in the Screening Analysis section of the Design Report as being "easy "moderate or "difficult." Factors considered in determining how projects were classified are described below: Construction costs I Easy 1 Moderate I Difficult 1 I Bicycle Projects I Less than $250,000 I $251,000- $4.5 million I More than $4.5 million I I Sidewalk Projects I Less than $2 million I $2 million $4 million I More than $4 million I Construction feasibility /difficulty Complex, hard -to- construct projects are those that would require the construction of bridges, extensive retaining walls, and cut/fill sections. Right -of- way /building impacts Projects that could be completed within existing rights -of way are considered "easy" because property acquisition adds schedule uncertainty, complexity and cost. INFORMATIONAL MEMO Page Environmental issues Projects that will require construction within wetlands, salmon- bearing stream environments and /or steep slope areas are considered complex because of the associated environmental review and permitting. Traffic analysis Some projects will require traffic analysis to determine whether a road diet to add bike lanes is feasible given traffic volumes. This extra analysis adds difficulty to the project. CIP status Projects in the Design Report already included in the CIP were classified as being "easier" than a project not already included in the CIP. Additional, policy related factors can be added to the above, with the potential of reclassifying some of the projects. (2) King County supported Walk and Roll programs /projects in Tukwila Lake to Sound Trail King County is the lead on the design and construction of a new east -west regional trail that will connect the Cedar River Trail in Renton with Puget Sound in Des Moines. A grant received in Spring 2009 for $800,125 is paying for the design of two segments of the trail a connection between the Renton and Tukwila approximately from Starfire Complex along the Black River to Oaksdale Avenue and extension of an existing trail in SeaTac from S 156 Street to Normandy Road. King County has submitted an application to PSRC for the latest round of Transportation Enhancements funding for construction of the section in SeaTac and Burien, since it is anticipated that this segment will be ready for construction if grant funds are awarded. Conducting environmental review, design, and obtaining permits for construction of the Tukwila Renton section is expected to take over a year, due to multiple sensitive areas in vicinity of the new trail segment. The City of Tukwila submitted a letter of support for King County's Transportation Enhancements application. West Side Trail to Green River Trail A different east west trail is being planned between SeaTac and Tukwila. The trail would connect the community centers between the two cities and the two existing adjacent recreational trails. The SeaTac recreational trail extends along Ambaum Boulevard from S. 154 Street to the SeaTac Community Center. King County as well as Tukwila and SeaTac have financially supported this planning effort. Bike Share King County received funding to begin a demonstration project. Bike share allows short term bicycle rental for trips of about 3 miles or Tess in urban areas. Utilitarian bikes are docked at kiosks where customers may use cards to pay for access to the bikes. Initial kiosks will be set up in Seattle and Redmond. Because King County would like to eventually expand the pilot program to South King County, King County is requesting a resolution of support from Tukwila, Renton, Kent, and SeaTac that would be used in additional federal funding requests.

Bike lanes are one -way facilities, with bicycles traveling the same direction as motor vehicles. Painted bike lanes can be used where ramps merge to /from a roadway to provide greater visibility. • Clearly delineates space in street for bicyclists • Sometimes, existing streets can be restriped or lanes narrowed to accommodate bike lanes • Increase site distance for vehicles entering or leaving driveways • Provide the clearest guidance for where each user should be in relation to each other • Maintenance needed on regular schedule to clear debris • It can be difficult for drivers to see children riding in the bike lane • Regular maintenance needed to repaint lane markings • Acquisition of ROW may be needed • Pavement markings at intersections or ramp merge areas should be understandable Wide Curb Lane / Sharrows Street furiture/ —� Landscaping Travel Lane Travel Lane (10 -14') (10 -14') Wide curb lanes are outside travel lanes at least 12' wide and preferably wider (14 - 15') that accommodate both vehicles and bicycles in the same travel lane. They can be signed as part of a bike route. A sharrow is a shared lane marked with a bike symbol within the pavement to alert motorists that the lane is shared by bicyclists. The 2009 Manual of Uniform Traffic Control Devices (MUTCD) recommends that when sharrows are installed, they be on streets with posted speed limits of 35mph or less. • Provide more room for both users than a standard 11' or 12' lane • Can often be incorporated within the existing street width without the need for widening or additional ROW • Sharrow markings provide more awareness to drivers • Less expensive to construct than bike lanes • Can encourage increased automobile speeds • Typically used only by experienced bicyclists • It can be difficult for drivers to see children riding in the curb lane • Acquisition of ROW may be needed • Sharrow markings require regular maintenance • This is usually only a good strategy for low volume street situations Bicycle Boulevard Streetfumiture / — ► Landscaping Chicane (Bike Chl icane' Travel *I Chicane B' ike' Area (Varies) Lane (Varies) Area (5') (Varies) (5') A bicycle boulevard is a shared, usually local road optimized for bike traffic.

Traffic calming techniques such as diverters, traffic circles, chicanes, speed humps are used to slow down vehicles. • Can be built within the existing roadway • Gives priority to the bicyclist, especially at intersections • Encourages low traffic volumes and speeds • Improves bicycle safety and efficiency • Can improve the aesthetics of the street • Can be a low cost solution • Requires a parallel road to divert vehicles to • Requires greater maintenance • Requires broader public outreach to agree on physical improvements • Potential fire and emergency vehicle concerns Tukwila Bicycle Friendly Routes and Sidewalk Segments Design Report — Chapter 1 Page 1 -4 Bicycle Friendly Route Cross Section Options - Continued Cross Section T Descri • tion Pros Cons Shared -Use Path Street furniture / Landscaping / Signage r- -.........--..■01 I, l'I II IIIiIIIAIN iu' 31411 1 Shared Use 1 I Path (10' -14') I Graded Area (2') Graded Area (2') A shared -use path is a separate trail for both pedestrians and bicyclists, usually within its own easement away from a road.
