The purpose of this project is to improve pedestrian safety at two existing crosswalk locations in unincorporated Walnut Creek.
The project consists of installing rectangular rapid flashing beacons for crosswalks at the intersections of Olympic Boulevard and Bridgefield Road, and Walden Road and Westcliffe Lane. The Olympic Bridgefield location will also have an advance RRFB due to a curve in the roadway. IN addition to RRFBs, at the Olympic/Bridgefield location a landing area will be constructed on the north side of the crossing with an American with Disabilities Act (ADA) accessible curb ramp and detectable warning surface to alert users that they are entering the roadway. At the south side of the crossing, a detectable warning surface will be installed that will tie into the existing Olympic Corridor Trail. Construction of the landing area on the north side may require partial removal of a fence and ivy. The Walden/Westcliffe improvements will include a passive detection system for the RRBs and detectable warning surfaces will be installed on both sides of the crossing. The Walden/Westcliffe improvements will tie into the existing Iron Horse Trail. Maximum excavation will be approximately three feet for installation of RRFBs
The project consists of minor alteration of existing public structure or facilities, involving negligible or no expansion of use beyond what is previous existing pursuant to section 15301(c) of the CEQA Guidelines. The project will not result in the removal of any scenic resource.
