landscape of the Turtle Bay Farm was graded to create cross-streets and the land was subdivided for residential development. Late 19th century An army enrollment office was established at Third Avenue and 46th Street, after the first Draft Act was passed during the American Civil War. On July 13, 1863, an angry mob burned the office to the ground and proceeded to riot through the surrounding neighborhood, destroying entire blocks. The New York Draft Riots continued for three days before army troops managed to contain the mob, which had burned and looted much of the city. The cove was filled in after the Civil War, serving as a valuable shelter from the often harsh weather on the river, and became a thriving site for shipbuilding. After the war ended, the formerly pastoral neighborhood was developed with brownstones. By 1868 the bay had been entirely filled in by commercial overdevelopment, packed with breweries, gasworks, slaughterhouses, cattle pens, coal yards, and railroad piers. By the early 20th century, Turtle Bay was "a riverside back yard" for the city, as the WPA Guide to New York City (1939) described it: "huge industrial enterprises—breweries, laundries, abattoirs, power plants—along the water front face squalid tenements not far away from new apartment dwellings attracted to the section by its river view and its central position. The numerous plants shower this district with the heaviest sootfall in the city—150 tons to the square mile annually". The huge Waterside Station, a power plant operated by the Consolidated Edison Company, producing 367,000 kilowatts of electricity in its coal-fired plant, marked the southern boundary of the neighborhood. There were also of slaughterhouses along First Avenue. With an infusion of poor immigrants having had come in the later part of the 19th century, and the opening of the elevated train lines along Second and Third Avenues, the neighborhood went into decay with crumbling tenement buildings. 20th and 21st centuries Many tenements were restored in the 1920s, and a large communal garden was established. Charlotte Hunnewell Sorchan saw promise in the run-down rowhouses of Turtle Bay. In 1918 she purchased twenty houses on 48th and 49th Streets between Second and Third Avenues; within two years she had renovated the enclave called Turtle Bay Gardens. An area between First and Second Avenues, and 41st and 43rd Streets was known as "Goat Hill"—goats and squatters ruled the area—and later renamed "Prospect Hill". Prospect Hill
