Towamencin Township is classified as a second-class township by the Commonwealth of Pennsylvania. The township is governed by a five-member Board of Supervisors, who are elected on an at-large basis and serve a six-year term of office. Elections to the Board of Supervisors take place in odd-numbered years, with elections staggered such that two seats come up for election every two years, with the exception of the sixth year in the cycle, when only one seat comes up for election. Under Section 607 of the Second Class Township Code the Board of Supervisors is "charged with the general governance of the township and the execution of legislative, executive and administrative powers in order to ensure sound fiscal management and to secure the health, safety and welfare of the citizens of the township." The Board of Supervisors is further empowered to appoint the township manager, as well as the membership of various boards and commissions, including the Zoning Hearing Board and the township's Planning Commission. The Board meets twice monthly to review all issues before the township and provide policy direction to the appointed staff. During the months of October, November, and December public hearings are held for the purpose of reviewing the budget for the following year.
