NOE - Notice of Exemption
Document Description
The purpose of this project is to improve pedestrian and bicyclist safety at the Delta De Anza Trail crossing at Alves Lane in unincorporated Bay Point. The De Anza Trail is an East Bay Regional Park District operated trail. The project consists of installing rectangular rapid flashing beacons (RRFB) at each trail crossing. The RRFBs will include a passive detection system which automatically activates the flasher for trail users. The RRFBs will be solar powered. The trail crossing improvements will be constructed to comply with the Americans with Disabilities Act (ADA), and include Detectable Warning Surfaces (truncated domes). The maximum depth of excavation will be approximately five feet for installation of the RRFB posts. At the trail crossing, the existing crosswalk will be retrofitted with a raised crosswalk for traffic calming and "No Parking" signs will be installed to improve visibility. The curbs surrounding the crosswalk will be painted red. Yield signs will be installed and the pavement will be re-striped with yield lines (in a "sawtooth" pattern) which will require motorists to come to a complete stop and allow trail users to cross Real Property transactions may be required. 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 or vegetation removal is anticipated. Best Management Practices (BMPs} will be implemented during construction.
