Background Implementation of the City's nonmotorized Walk and Roll Plan is proceeding with design and engineering being done by Perteet Engineering for bike and selected pedestrian facilities. Discussion A design report highlighting the options available for the selected routes has been drafted. A map showing the recommendations is attached (see Attachment). Interim improvements The possibility of creating bike lanes on all streets is not feasible in the short term because of right -of -way, cost and other constraints. Interim solutions such as "Share the Road" signage, climbing lanes on the uphill, and sharrows, which can be used on lower volume roads, are being recommended as interim improvements. These improvements will exist until street reconstruction is funded or major redevelopment of adjacent parcels is undertaken. Bicycle Boulevards To compensate for the lack of bike lanes on major travel routes, and to provide a bike friendly alternative to major travel routes that have high posted speeds and high traffic volumes (including truck traffic), the concept of "bicycle boulevards" is being suggested by the City's consultant. Bicycle boulevards are streets that have improvements that make bicycle travel safer and more convenient by reducing automobile traffic and speeds and supporting bicycle through movement. Streets for bicycle boulevard improvements are chosen when they are logical, direct, and continuous routes; are well marked and signed; provide convenience to desired destinations; and can provide comfort and safety at intersections. Ideal streets for bicycle boulevard improvements have posted speeds of 25 miles per hour or less and average daily auto trips of 4,000 or less. Some common "bicycle boulevard" improvements include signage and pavement markings, automobile traffic calming measures such as electronic speed reader signs to encourage posted speed limits, and intersection improvements, such as pavement markings that indicate bicycle placement on loop detectors and curb extensions or bulb -outs. At this time, a bicycle boulevard is being recommended for 42 Avenue South, from S. 160 Street to East Marginal Way, and for S 135 Street, from 37 Ave S to Military Rd S. INFORMATIONAL MEMO Page 2 A traffic analysis is needed that includes such data as traffic volumes, accidents, vehicle type, turning movements and speeds, for a number of the routes in the design report including the bike boulevard recommendations. Recommendation Information only Staff will finalize the pedestrian and bicycle design report and proceed to 10% design per the contract. The final report will be presented to Council and will be used for the next update of the Capital Improvement Program.
