It has about 94 acres of open water, stone basin walls, gate houses and landscaped grounds.","why_significant":"The nomination presents the reservoir as an important piece of New York City's water supply engineering, containing both the Old and New Croton Aqueducts within its massive east wall. It also argues the property exemplifies Olmsted's landscape and city planning principles, combining a utilitarian reservoir with a naturalized public park setting. Its Roman-inspired stone gate houses and 1938 WPA Art Deco superstructures add architectural interest.","narrative":"Jerome Park Reservoir is a 125-acre reservoir-park in the northwest Bronx, built between 1895 and 1906 as part of the Croton Aqueduct system. About 94 acres of open water sit within massive quarried-stone walls and a northern core wall dam with earthen embankments. The east wall, along Goulden Avenue, encloses both the Old and New Croton Aqueducts; the older aqueduct was removed and rebuilt inside the new wall about 1899. Gate houses in a Roman-inspired style, with voussoir arches and rock-face granite, control the water, and their brick superstructures were added by the WPA in 1938 in a restrained Art Deco manner. Landscaping includes retaining walls, gateposts, iron fences, terraces and rock outcroppings. The district includes 19 contributing resources and is described as reflecting Frederick Law Olmsted's ideas about combining reservoirs with parks. Adjacent parks were later carved from the original grounds, and the reservoir has been fenced off since World War II.","period_of_significance":null,"architect_builder":null,"architectural_style":"Late Victorian: Civic Roman-inspired design; Modern Movement: Art Deco; Late 19th and Early 20th Century Landscaping: The Pleasure Ground movement","criteria":[],"status_note":"Still serves as a waterworks and park; fenced off from public access since World War II.
