Overlays
Housing suitability (Southern Tier analysis)
The suitability layers from the
Southern Tier map. Frequent transit = 4 or more departures per hour within a half mile; that layer overlaps Most suitable.
Public water and sewer service areas
Approximate service areas from EPA water system boundaries (2026) and NYS sewersheds (2022). Unshaded land relies on private wells and septic. Not for parcel-level decisions. Same layer as Infrastructure detail on the
Southern Tier map.
Utility infrastructure (by municipality)
A rating for the whole town or city, not where its pipes run. Municipalities with neither water nor sewer, or no reported data, are not shown. Same layer as the Utility infrastructure suitability input on the Southern Tier map.
A regional copy of the Housing ready · block group layer on
