One of the first sites considered was Jones's Wood, a 160-acre (65 ha) tract of land between 66th and 75th streets on the Upper East Side. The acquisition was controversial because of its location, small size, and cost.[39][40][41] A bill to acquire Jones's Wood was invalidated as unconstitutional,[42][43] and so attention turned to a second site: a 750-acre (300 ha) area known as "the Central Park", bounded by 59th and 106th streets between Fifth and Eighth avenues.[42][44] Croton Aqueduct Board president Nicholas Dean, who proposed the Central Park site, chose it because the Croton Aqueduct's 35-acre (14 ha), 150-million-US-gallon (570×10^6 L) collecting reservoir would be in the geographical center.[42][44] In July 1853, the New York State Legislature passed the Central Park Act, authorizing the purchase of the present-day site of Central Park.[45][46]
