Computed 2026-11-07 from Suffolk County GIS (hamlet boundaries, sewer districts, groundwater management zones, FEMA flood zones, protection areas, tax parcels). Shares are of land area; a district boundary is not a hookup, and some village-run systems are missing from the county layer. Method and full table.
Sewer coverage
No active county sewer district covers Manorville on the county's GIS layer, so homes here use cesspools, septic tanks or I/A systems unless a village or private plant serves them. Counting lots instead of land: about 3,226 of the 3,226 one-family lots touching Manorville lie outside any active sewer district, and those homes rely on on-site systems. For comparison, the nearest places: Calverton (6% sewered, median lot 0.55 ac); East Moriches (0% sewered, median lot 0.53 ac); Eastport (0% sewered, median lot 0.63 ac). By active-sewer share Manorville ranks 92 of the 165 Suffolk hamlets and villages we measured.
Groundwater, lots and flood exposure
Groundwater management Zone III: Article 6's minimum lot for a new home on an on-site system here is 40,000 sq ft, unless the density is met another way or an exemption applies. County parcel records show 3,226 one-family lots touching Manorville, with a median of 0.92 acres (about 40,200 sq ft), above that minimum and the 19th-largest median lot in our Suffolk table. Also mapped: 2% of the land is in FEMA's 1%-annual-chance flood zone; 98% is in a Special Groundwater Protection Area; 40% is Pine Barrens Core; 57% is Pine Barrens Compatible Growth Area.
For most Manorville homes the main running cost is pumping; when a cesspool fails, the replacement must include at least a septic tank, and grants can cover most of an I/A system.
