Name and history
Statewide, other Colerain Townships are located in Belmont and Ross counties. The village of Colerain was laid out in 1790 by surveyor John Dunlap, who was a native of Coleraine, Ireland. Fort Coleraine, aka Dunlap's Station, was one of the earliest attempts to settle the area despite the natives who had resided here for centuries without signing any land treaties.
The township was organized in 1794.
The township is governed by a three-member board of trustees, who are elected in November of odd-numbered years to a four-year term beginning on the following January 1. Two are elected in the year after the presidential election and one is elected in the year before it. There is also an elected township fiscal officer, who serves a four-year term beginning on April 1 of the year after the election, which is held in November of the year before the presidential election. Vacancies in the fiscal officership or on the board of trustees are filled by the remaining trustees.
