About this map

The Central Islip State Hospital complex dominates the central landscape of this Suffolk County survey, its extensive grounds and filter beds situated just south of the Long Island railroad tracks. This mid-century view captures a period of intense suburban expansion as the Long Island Expressway and Southern State Parkway carve through the terrain, connecting established villages like Smithtown and Village of the Branch with emerging residential tracts in East Brentwood and Hauppauge.

The southern reaches of the map highlight the transition toward managed conservation and institutional land use, anchored by the Bayard Cutting Arboretum along Connetquot Brook. Near the eastern boundary, the shoreline of Lake Ronkonkoma remains a focal point for the surrounding community of Ronkonkoma. Local heritage is preserved in the numerous parochial institutions and cemeteries, including St Patricks Cem and the Academy of St Joseph, which serve as permanent markers amidst the rapidly changing landscape of postwar Long Island.
