RECOMMENDATION(S): (CONT'D)

DIRECT the Director of Conservation and Development to file a Notice of Exemption with the County Clerk, and

AUTHORIZE the Public Works Director or designee to arrange for payment of a $25 fee to Conservation and Development for processing, and a $50 fee to the County Clerk for filing the Notice of Exemption.

ADOPT Resolution No.2017/31 to APPROVE and AUTHORIZE the Public Works Director, or designee, to submit a 2017/2018 Transportation Development Act (TDA) Grant Application to the Metropolitan Transportation Commission in the total amount of $78,500, for the fiscal year 2016/2017 for the Walnut Creek Crosswalk Improvements Project.

FISCAL IMPACT:

70% Federal Highway Safety Improvement Program (HSIP) Funds, 30% Transportation Development Act (TDA) Funds.

BACKGROUND:

The Project consists of installing rectangular rapid flashing beacons (RRFB), 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 the RRFBs, at the Olympic/Bridgefield location a landing area will be constructed on the north side of the crossing with an Americans 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 RRFBs 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. Real Property transactions may be necessary in support of the project. Utility relocations may be necessary. 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 and property owners will have access at all times. No tree removal is anticipated however, some vegetation removal may be necessary. In addition, trees and vegetation may need to be trimmed. If tree roots are impacted during construction, they will be cut cleanly. 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 to protect storm drain inlets. General Plan Conformance will be necessary from the City of Walnut Creek.

CONSEQUENCE OF NEGATIVE ACTION:

Delay in approving the project may result in a delay of design and construction, and may jeopardize funding.
