rail project into the 2000 report Blueprint for the 21st Century, sponsored by the Metropolitan Transportation Commission (MTC). The 1999 report evaluated the cost estimates for rehabilitating the line from the 1996 report and concurred that the timber trestles should be replaced, the lower portion of the steel through-trusses should be replaced, and the two swing spans were severely corroded but operable in 1996. The 1999 Dumbarton Rail Corridor Study estimated the necessary improvements would cost a total of . In 2000, Santa Clara County voters approved Measure A, which set aside a portion of the funds generated from a half-cent sales tax increase for the Dumbarton Rail Corridor. A 2000 San Mateo County grand jury found that though the county of San Mateo would contribute the highest amount among the three funding counties (Alameda, San Mateo, and Santa Clara), the Dumbarton Rail service was projected to mainly aid Alameda County residents in reaching Santa Clara county destinations. California State Senator Jackie Speier introduced a bill in February 2000 that would devote to rehabilitating the Dumbarton Rail Bridge to add Altamont Corridor Express (ACE) service from Newark to San Jose; however, ACE officials rebuffed the offer, saying the bill added no money for purchasing new trains or funding operating costs. By being included in the Blueprint for the 21st Century, MTC programmed funds for the Dumbarton Rail Corridor (DRC). DRC was identified as one of the nineteen high-priority rail and bus projects for transit expansion in the Bay Area as part of MTC's adoption of Resolution 3434 in December 2001. In 2001, MTC estimated the total capital cost for DRC was ; of that, 91% had been secured or was pending via local sales taxes in San Mateo, Alameda, and Santa Clara Counties. 2003–2007: Scope and cost growth In November 2004, MTC released a draft plan for spending over the next twenty-five years, entitled Transportation 2030, which included full funding to rehabilitate and reactivate the Dumbarton Rail Corridor. In 2004, the total capital cost had increased to an estimated . However, Regional Measure 2, which had been passed by voters earlier in March 2004, set aside an additional for the Dumbarton Rail Corridor project from increased toll bridge revenues. Much of the cost increase was driven by the 2003 Dumbarton Rail Corridor Project Study Report, which identified several deficiencies in the existing infrastructure. The 2003 Project Study Report proposed replacing
