Mayhew Way and Cherry Lane Trail Crossing Enhancements Project No. WO1025, CP#19-43

The purpose of this project is to improve trail user safety at two existing crosswalks located in unincorporated Walnut Creek and on the border of the City of Pleasant Hill. The crosswalks are for East Bay Regional Park District trail crossings. The project consists of installing rectangular rapid flashing beacons (RRFB) for two crosswalk locations: 1) at the intersection of Mayhew Way and Iron Horse Regional Trail; and 2) at the intersection of Cherry Lane and Contra Costa Canal Trail. The project will be coordinated with the East Bay Regional Park District, the Contra Costa Water District, the Iron Horse Corridor Management Program Advisory Committee, other utility agencies, and other stakeholders in the area. The RRFBs will include a passive detection system which automatically activates the flasher for trail users. At the Cherry Lane intersection, RRFBs will be powered by existing electrical meters and existing pedestrian push-buttons may be co-opted. Both trail crossings will be constructed to comply with the Americans with Disabilities Act (ADA), including Detectable Warning Surfaces. At both trail crossing locations, pavement will be re-striped with yield lines (in a "shark's teeth" pattern) to increase visibility. At the Mayhew Way crossing, bulb-out islands will be installed for traffic calming. The maximum depth of excavation will be approximately five feet for installation of the RRFB posts. An excavation depth of approximately three feet will be required for utility trenching across the roadway and for bulb-out construction. Real Property transactions may be required . Utility adjustments or relocation may be necessary in support of the project. Temporary full or partial lane closures may be necessary during construction. If closures are necessary, traffic control will be implemented. At least one lane will remain open and emergency vehicles will have access at all times. No tree removal is anticipated, however some vegetation removal may be necessary throughout the project area to improve crosswalk visibility. If construction or disturbance to trees or vegetation is conducted during the breeding season for migratory birds and raptors (generally February 15 through August 31 ), a nesting bird survey will be conducted prior to construction. Best Management Practices (BMPs) will be implemented during construction. General Plan Conformance will be necessary from the City of Pleasant Hill.
