Drag to pan. Hold Ctrl (⌘ on Mac) and scroll to zoom, or pinch with two fingers. Pins are colored by complaint category and clustered when zoomed out — click a cluster to expand, click a pin to open the full 311 record. Hovering anywhere over a neighborhood also surfaces its own stats card in the top-left corner — that card is per-neighborhood, not per-cluster, so nearby clusters in the same neighborhood show the same numbers on purpose. When you choose a category in the filter below, the map recolors each pin by its specific problem detail (descriptor).
Each square is one calendar day. Color intensity scales from light (fewer reports) to deep blue (most reports). Hover or tap a day for the exact count. Today is partial — 311 data has a ~24-hour ingestion lag.

SidewalkSnitch reports in Manhattan CB9
Every report on this page comes straight from NYC 311.
SidewalkSnitch doesn't submit to 311 yet — so right now the city's 311 data above is the complete record for Manhattan CB9. Once SidewalkSnitch begins filing to 311, those reports will appear in this same dataset automatically — there's no separate SidewalkSnitch number to reconcile.
All data on this page comes from NYC Open Data, provided under the NYC Open Data Terms of Use. SidewalkSnitch is an independent civic tool and is not affiliated with the City of New York.
Underlying map data for the interactive basemap. The map renders live with MapLibre GL using CARTO's Positron vector tiles (built from OpenStreetMap data), rotated to align Manhattan's avenue grid. Attribution required by the ODbL license.
Data is fetched server-side via the Socrata Open Data API (SoQL). Freshness is not on a fixed schedule — check the "Last fetched" timestamp below for this page load. Last fetched: Jul 29, 2026, 2:37 AM ET.
