The City of Port Arthur is governed by a council-manager form of government where the City Council sets city policy and theCity Manager is responsible for city operations.
The council consists of a mayor and eight council members. All council members are elected for one three year term up to three consecutive terms. Elected officials are under a mixed system of single-member districts and at-large seats. Four council members are elected from single member districts, two from combined districts and two at large.
At Large Districts
At large candidates are elected to represent the whole city; all voters can vote for candidates running for an at large seat. At large candidates may reside in any area of the city.
A single-member district is a geographically defined voter district represented by a single elected official. Only registered voters that live within the specified district's boundaries can vote for candidates who run for a seat in the district. Candidates must live in the single-member district in which they run.
