Zambales Provincial Board
The Zambales Provincial Board is the Sangguniang Panlalawigan of the Philippine province of Zambales.
The members are elected via plurality-at-large voting: the province is divided into two districts, the first district sending three members, and the second district sending seven members to the provincial board; the number of candidates the electorate votes for and the number of winning candidates depends on the number of members their district sends. The vice governor is the ex officio presiding officer, and only votes to break ties. The vice governor is elected via the plurality voting system province-wide.
The districts used in appropriation of members is coextensive with the legislative districts of Zambales, with the exception that Olongapo, a highly urbanized city, is excluded in the first district.
Aside from the regular members, the board also includes the provincial federation presidents of the Liga ng mga Barangay, the Sangguniang Kabataan and the Philippine Councilors League. Zambales's provincial board also has a reserved seat for its indigenous people.
