What We Know About This Town.
Town of Islip includes Islip (hamlet), Islip Terrace, East Islip, West Islip, Central Islip, Bay Shore, Brightwaters, Sayville, West Sayville, Oakdale, Great River, Bohemia, Holbrook, and parts of Holtsville. Around 325,000 residents, the largest town in Suffolk by population.
Sewer coverage is mixed: Southwest Sewer District covers some of the denser southern hamlets, but many homes, especially waterfront and older residential, remain on private disposal.
What We Hit When We Dig.
Islip's ground varies significantly:
- Southern waterfront (Bay Shore, Brightwaters, West Islip, Oakdale, Sayville): High water table, tight waterfront setbacks, sensitive watershed. Tank anchoring, I/A often required.
- Central Islip corridor (Central Islip, Islip, East Islip): Sandy loam, moderate water table, straightforward installs.
- Northern Islip (Bohemia, Holbrook, Holtsville): Sandy, Pine Barrens-adjacent, excellent percolation but sensitive-zone overlays in some spots.
- Great River: Nissequogue-adjacent, river setbacks apply.
