Flooding and water in Scarsdale
- Westchester County’s Long Island Sound watershed program lists this municipality in the watershed study areas for “Mamaroneck and Sheldrake Rivers; Mamaroneck Harbor”, “Hutchinson River”, “Bronx River”. [source]
- The village’s own sewer-compliance program notes that seasonal groundwater combined with poor foundation drainage or failed waterproofing leads to sump pumps being wired into the sewer, which is not allowed. [source]
- Flood maps are address-specific. Check your own address on FEMA’s flood map service, and ask any contractor how they treat a high water table on your lot. [source]
Permit notes for Scarsdale
From the municipality’s own pages, retrieved Oct 2026. Rules change, so call the building department before work starts.
- The village says all new installations of sump pumps, drainage facilities and related items require village permits. Call Engineering at 914-722-1106 before you sign a contract. [source]
- Sump discharge should go to an owner-maintained dry well or detention basin; it may not go to a laundry tub, sink or sanitary sewer line. Connecting to a public stormwater drain needs the Village Engineer’s written permit. [source]
