Most of the farmland surrounding the quarries and mills of the cement plants were owned by Morris Frace. He had the area surveyed and laid out in building lots in 1898. It was not long after the establishment of the community's first Post Office in 1903, that the people started the move towards incorporating Alpha as a town separate from Pohatcong Township. One of the leading figures in the move was Harvey Seifert, who became the first Mayor. After a desperate struggle, the Borough of Alpha
was incorporated as a municipality by an act of the New Jersey State Legislature and Governor Woodrow Wilson on
June 26, 1911
Some residents of the borough still refer to the western side of Alpha as 'Alpha' and the eastern section as 'Vulcanite' based on the respective locations of the old cement plants, which discontinued operations and were razed shortly after World War I.
