Annexation of Harmon The real estate development com- pany of Wood , Harmon and Com- pany purchased the farm which constituted the area known as Har- mon and laid it out in streets and lots in 1907. Lots were sold between 1907 and 1909 , and in 1909 a few houses were built . Wood , Harmon and Company maintained the streets , furnished water and elec- tricity and provided garbage col- lection . In December 1926 , when Harmon had about 140 homes , a small num- ber of residents signed a petition to incorporate Harmon as a village . This proposition met with so much opposition that it failed . In April 1928 , a mass meeting was held in the Croton High School and the Harmon Planning Commit- tee was formed , with the purpose of deciding whether Harmon should CROTON DAM This Page Donated By NATHANIEL P. BROOKS , M.D. remain a hamlet , incorporate or annex to Croton - on - Hudson . The committee could not agree and was dissolved . On July 21 , 1928 , the Harmon Annexation Party of 102 members , with Ernest S. Holcombe as chair- man , was organized at a meeting at Mikado Inn . In November and December , 1929 , petitions were signed by over 70 per cent of voters to annex Harmon and Mt. Airy , another section to the northeast and adjoining Croton- on - Hudson , as well as a small rural section to the north which was known as Oscawana . The proposi- tion was favorably carried by a public referendum held on June 25 , 1930 , and the annexation became effective July 1 , 1930. Thus was created the present enlarged village of Croton - on - Hudson .
