BACKGROUND The City of Pleasanton entered into a development agreement in October of 2000 with GHC Bernal Investors. Included within the development agreement were provisions for the payment and construction of the 1 -680 at Bernal Interchange improvements. While the cost of the construction would be the responsibility of the developers, the construction of the improvements would be the responsibility of the City. The City was required to stage the construction of the improvements so that the ramp intersections maintained an acceptable level of service D. The recent update of the 1996 General Plan made significant changes to the circulation network. This 2005 update still identified the need to improve the 1 -680 at Bernal interchange. The changes to the circulation network, however, altered roadway volumes enough to require a new analysis of the design alternatives of the interchange. The City authorized a Traffic Operations Evaluation Memorandum in December 2008 to review existing and future traffic volumes, evaluate various interchange modification alternatives, and identify a preferred interchange alternative. The memorandum resulted in recommended design alternative and improvements that differed substantially from improvements identified in the 1996 General Plan. The 2008 operations memorandum was followed by a more detailed feasibility study of the preferred alternative to determine if the "operationally" preferred alignment was geometrically feasible. The study found the preferred alternative was feasible and constructible. The study recommended plans, specifications and estimates be developed for review by Caltrans as soon as travel demand forecasts showed that this interchange modification would be necessary to maintain an acceptable level of service. As a result of this analysis, the City solicited prospective consultants through the Request for Proposals process to provide plans, specifications, and estimates (PS &E), environmental certification, and Caltrans approval for the 1 -680 / Bernal Avenue interchange improvements. The City received five proposals from qualified civil engineering consulting firms. Staff identified BKF Engineers of Pleasanton as the preferred consultant for the project. BKF Engineers has completed similar work for other jurisdictions, including recent improvements along 1 -580 in the Tri- Valley. Their work has been reliable and professional. The proposed work will be for an amount not to exceed $297,666. The project should be designed, approved and ready to construct in 9 -12 months. This timeline will allow the project to be advertised for construction in late summer 2011. Page 2 of 3
