19 Oct East of Hills System Tunneling Study (East Bay Municipal Utility District)
As part of a tunneling feasibility study for two alignments between East Bay Municipal Utility District facilities in Orinda, Lafayette, and Walnut Creek; W-Trans reviewed multiple segment alternatives for potential transportation CEQA impacts. For each segment, potential impacts to alternative modes were identified and mitigations provided such as detour routes, implementation of construction signage, and relocation of transit facilities. As part of the review, coordination was required to determine the limits of the construction areas, lane closures, and length and time of construction. Each segment was reviewed for potential hazardous conditions requiring transition tapers, sight line obstructions, and temporary signal timing and/or re-phasing.
