Notes

A GIS-first catalog: parcels, boundaries and infrastructure. No budget, payroll or 311-style civic datasets were seen. That is from an earlier pass and was not re-checked.
datahub-wcgis.opendata.arcgis.com is a legacy site of the same county org. GeoHub v2 is canonical (Audit 2026-11-05).
Cities in the county (Mount Vernon, New Rochelle, White Plains, Yonkers) lean on this hub for county-level layers.
