recommends use of the green K71 bollards shown in the left image as they are equally <br /> visible, but the bollard's wider profile discourages vehicles from hitting them. <br /> LL.• . f to.. <br /> y <br /> r <br /> 3 /i _ <br /> low <br /> _.. 4i. .� <br /> ilIC 40 elli, ar . <br /> Figure 7 — K71 (green 12-inch bollard) and standard 2-inch white delineator <br /> Maintenance: Maintenance will be a key aspect of the first phase. The delineators <br /> provide the physical separation between vehicles and bicycles, but the delineators also <br /> create a barrier that blocks the ability for a standard street sweeper to be used. Smaller <br /> street sweepers are available that can sweep within the protected bike lane, but they <br /> are not a standard vehicle owned by street sweeping contractors. <br /> The current street sweeping contract requires the contractor to "hand sweep" areas that <br /> are inaccessible by the street sweeping vehicle. However, hand sweeping is <br /> infrequently completed and is normally conducted only on a request basis. Phase 1 will <br /> allow staff to determine the frequency of hand sweeping necessary and include this <br /> added cost in future contracts or require/purchase a smaller street sweeper to clean the <br /> corridor. <br /> Phases 2-4: Extension of Quick Build Improvements <br /> As conceptualized in the Bicycle and Pedestrian Corridor Plan, the lower cost "quick <br /> build" concept would be extended in subsequent phases from Hopyard Road to Foothill <br /> Road and from Hacienda Drive to Fairlands Drive. However, as described below, these <br /> phases may be bypassed as a result of the implementation of the Reconstruction <br /> Project. <br /> Phase 5: Intersection Improvements <br /> Phase 5 will install protected intersections at Foothill Road, Hopyard Road, Willow <br /> Road, Stoneridge Drive and Santa Rita Road. This phase has varying levels of traffic <br /> signal modifications and will likely be completed one intersection at a time. Stanley <br /> Boulevard at Valley Avenue/Bernal Avenue provides an example of a protected <br /> intersection design within the city. <br /> Phase 6: Install Permanent Bikeway Separation (in conjunction with West Las Positas <br /> Reconstruction) <br /> Page 11 of 14 <br />
