In 1907 Bassett was appointed by Governor Charles Evans Hughes to the New York Public Service Commission, where he served until 1911. During this time he aided in the development of the Dual Contracts (also called the dual subway plan) for the New York City Subway, which resulted in subways connecting Manhattan and Brooklyn for the first time, and he also championed the streamlining of train movement by abolishing stub-end terminals in favor of the "pendulum" method of train movement. He was vice-chairman of the Brooklyn Committee on City Plan, for which a report was published in 1914. He was chairman of the Heights of Buildings Commission in New York City, the final report of which 1916 presented the first Zoning Resolution of the City of New York, which was the first comprehensive zoning ordinance in the United States. He consequently served posts of counsel to the Zoning Committee of New York, the Regional Plan of New York and Its Environs, and the New York City Planning Commission. A member of the Advisory Committee on City Planning and Zoning, Bassett was appointed by then U.S. Commerce Department Secretary Herbert Hoover to serve as president of the National Conference on City Planning. Two articles written to commemorate the centennial of the first New York zoning ordinance in 1916 highlighted his role in its creation." Carl Weisbrod, the current chairman of the City Planning Commission,] credited Mr. McAneny and Mr. Bassett with creating a revolutionary document couched in accepted common-law and constitutional doctrines: that landowners are not entirely free to create nuisances to those around them; and that local governments may police conduct in the name of public health, safety and welfare." "Bassett (1863- 1948) served as chairman for both zoning commissions and has been called the “father” and “midwife” of American zoning for the prominent role he played in establishing New York's code and helping to institute the system around the country."
