He will head the Budget Subcommittee on Resources and Transportation, his office announced Dec. 15.
Mr. Gordon, who served 13 years as a San Mateo County supervisor, has closely followed the high-speed-rail debate and has called for creation of a new oversight structure for the authority's governing board, with greater transparency and local representation.
Other departments and agencies over which the subcommittee has authority include the state Air Resources Board, the Department of Water Conservation Resources, the Department of Fish & Game, and the Department of Transportation.
Mr. Gordon will also serve on the full Budget Committee, the Budget Subcommittee on Oversight, and the standing committees of Local Governments, Health, and Revenue & Tax Committees.
He was elected in November to represent the 21st Assembly District, which includes Atherton, Menlo Park, Portola Valley, Woodside, as well as San Carlos, Redwood City, East Palo Alto, Palo Alto, Los Altos, Los Altos Hills, Monte Sereno, Los Gatos and the Almaden Valley.
In addition to serving on the San Mateo County Board of Supervisors, Mr. Gordon was president of the California State Association of Counties in 2008-09.
"I am pleased that I will serve on a variety of committees in diverse issue areas, and I will strive to fulfill my pledge to bring better governance to Sacramento and help tackle the state budget problems dominating the state today," Mr. Gordon said of his appointments.
