Between 1821 and 1855, New York City's population nearly quadrupled. As the city expanded northward up Manhattan, people were drawn to the few existing open spaces, mainly cemeteries, for passive recreation. These were seen as escapes from the noise and chaotic life in the city, which at the time was almost entirely centered on Lower Manhattan. The Commissioners' Plan of 1811, the outline for Manhattan's modern street grid, included several smaller open spaces but not Central Park. As such, John Randel Jr. had surveyed the grounds for the construction of intersections within the modern-day park site. The only remaining surveying bolt from his survey is embedded in a rock north of the present Dairy and the 66th Street transverse, marking the location where West 65th Street would have intersected Sixth Avenue. Site By the 1840s, members of the city's elite were publicly calling for the construction of a new large park in Manhattan. At the time, Manhattan's seventeen squares comprised a combined of land, the largest of which was the Battery Park at Manhattan island's southern tip. These plans were endorsed in 1844 by New York Evening Post editor William Cullen Bryant, and in 1851 by Andrew Jackson Downing, one of the first American landscape designers. Mayor Ambrose Kingsland, in a message to the New York City Common Council on May 5, 1851, set forth the necessity and benefits of a large new park and proposed the council move to create such a park. Kingsland's proposal was referred to the council's Committee of Lands, which endorsed the proposal. The committee chose Jones's Wood, a tract of land between 66th and 75th streets on the Upper East Side, as the park's site, as Bryant had advocated for Jones Wood. The acquisition was controversial because of its location, small size relative to other potential uptown tracts, and cost. A bill to acquire Jones's Wood was invalidated as unconstitutional, so attention turned to a second site: a area known as "Central Park", bounded by 59th and 106th streets between Fifth and Eighth avenues. Croton Aqueduct Board president Nicholas Dean, who proposed the Central Park site, chose it because the Croton Aqueduct's , collecting reservoir would be in the geographical center. In July 1853, the New York State Legislature passed the Central Park Act, authorizing the purchase of the present-day site of Central Park. The board of land commissioners conducted property assessments on more
