Overview of Trail Improvements 1.3 Mile Trail Paving and Striping Signage/Interpretation Accessibility K-Rail Improvements Overlooks Accessibility
Paving/ Striping 6 bike lanes each way 10-12 pedestrian/ equestrian Repair and resurface existing asphalt pavement (microsurfacing)
Before K-Rail simulation
Microsurfacing Prevents pavement degradation- seals underlying surface from water and air intrusion More skid resistant than slurry (micro 0.8 vs. slurry 0.5 friction coefficient) Longer lifespan than slurry (5-7 years vs. 3-5 years) Widely used throughout Bay Area and California
Paving and Striping
User Safety Signage Speed limit paint on trail pavement and posted on each end Horse signs posted at each trailhead K-rails and cable fencing keeping people back from cliff edge 2 buffer between bike lane and K-rail Ambassadors- verbal warnings
Signage Remove existing roadway signage New regulatory signage (minimize number, and location to protect views) Interpretive panels
Accessibility Improvements Bathroom & drinking fountains (north and south trailheads) Interpretive panels Overlooks Observation scopes ADA access provided to overlooks from parking per County trail standards
K-Rail Improvements Moving K-rail for smooth trail edge Removing limited K-rail to expose old rock wall Power wash and paint tan Clear debris and weeds along K-rail Future opportunities artistic teaming/ fundraising
Environmental Review May 2002 EIS/EIR supplement to 1986 certified by Caltrans Sept. 2004 California Coastal Commission upheld July 2004 approved CDP Trail improvements are consistent with CDP Project will provide memorandum including detailed analysis of biological resources
Potential Wetlands Four potential Wetlands Two require K-rail relocation Supervision of a qualified wetland biologist
Bird Nesting Protection Trail is directly adjacent to important bird nesting locations philseu.blogspot.com/2011/ Birds are acclimated to vehicular traffic only Views of pedestrians may cause nests to be abandoned Bird nest protection is critical Bird species include: Peregrine Falcon, Murres, Brandt s, Pelagic Cormorants, Western Gulls, Pigeon Guillemots, Brown Pelicans
Bird Nesting Protection 2011 Common Murre Report recommends visual barrier Nesting season January- September Year round fencing option is preferred Visual Barrier Sensitive Nests/ Breeding Areas
