BACKGROUND The I-680 / Bernal Avenue interchange project, CIP No. 005068, is in Phase 1 of the construction process. This first phase includes the construction of a traffic signal at the southbound ramps. These Phase 1 improvements are necessary to improve the delay and congestion experienced in the peak hours. Phase 2 of the project includes interchange modifications to the ultimate configuration. DISCUSSION The interchange design for Bernal Avenue at Interstate 680 was included in the 1996 General Plan and provides for several changes, including the addition of a traffic signal (currently underway as Phase 1 of the interchange project). In addition to this change, a major reconfiguration was identified that included the removal of the existing southbound loop off-ramp and the creation of a southbound loop on-ramp. The construction of this ultimate configuration is considered Phase 2 of the project. The City is currently in the process of updating the General Plan. Several changes in land use and roadway network in the updated General Plan change the traffic patterns anticipated in the 1996 General Plan. A design alternatives analysis is needed to evaluate the need for the planned Phase 2 improvements and/or determine if a different design is necessary. A preferred alternative will be further evaluated and drafted to determine the design feasibility and the next steps in the design process. In June 2008, staff solicited prospective consultants through the Request for Proposals process. In July, staff received four proposals from qualified transportation consulting firms. Staff identified Kimley-Horn and Associates, Inc. of San Ramon, California, as the preferred consultant for the project. Kimley-Horn has prepared similar studies for the City of Pleasanton and other jurisdictions and its work has been reliable and professional. Kimley-Horn was the consulting firm that designed the traffic signal for Phase 1 of the project and is familiar with the project and project area. The proposed work will be for an amount not to exceed $39,960. Submitted by: Fiscal Review: Approve y: Rob Wilson David~P.
