Great Neck Manor flood history
No days with roads at risk since 1996
Estimates, not records of actual flooding. Each day is NOAA's verified high water at the tide gauge, run through FloodRoute's flood model on today's roads and elevations, in dry weather. Drains, levees, tide gates, rain, road changes and elevation error all mean real conditions differed. Not for property, real-estate, insurance, lending, engineering or legal decisions.

About this data: method, sources and free downloads
Since 1996, NOAA's Sewells Point tide gauge hasn't recorded water high enough for FloodRoute's model to put a road in Great Neck Manor at risk.
For every day since 1996 we take NOAA's verified highest observed water at the tide gauge, adjust it to the town's prediction station exactly as the live forecast does (the gauge's departure from the tide tables, minus the departure already built into our calibration), and run FloodRoute's flood model on today's road network and street elevations. A day counts when at least one road in the town is at or below that water level by the model's rules. Rain is not included, so wet days were likely worse.
Gauge: NOAA 8638610 (Sewells Point). Heights are feet above MLLW.

FAQ
Great Neck Manor flood history: questions, answered
How often do roads flood at high tide in Great Neck Manor?
In NOAA's record since 1996, water at the Sewells Point gauge never reached the level where FloodRoute's model puts a Great Neck Manor road at risk.
Is this a record of actual flooding in Great Neck Manor?
No. Estimates, not records of actual flooding. Each day is NOAA's verified high water at the tide gauge, run through FloodRoute's flood model on today's roads and elevations, in dry weather. Drains, levees, tide gates, rain, road changes and elevation error all mean real conditions differed. Not for property, real-estate, insurance, lending, engineering or legal decisions. Neighbor flood reports in the FloodRoute app are the ground truth we use to check and improve the model.
