Today's satellite waterline in blue (Sentinel-2, ±10 m); the USGS mapped shoreline (through ~2009) in grey. Where the federal erosion rate projects the waterline in red — over the houses that are there now.
Westhampton sits directly downdrift of the Shinnecock jetties and behind a groin field — a stretch engineered a half-century ago that starved the barrier of sand. The federal long-term record puts erosion here at up to a meter of shoreline a year. In 1992 the barrier breached here and took houses with it. The projection above isn't a forecast of doom — it's the existing rate, carried forward, laid over the homes that stand there today.
Pulled this moment from the federal feeds — the same stack that runs the console. This is what "standing watch" means: the sea state, the tide, the flood exposure, and any storm in the basin, read continuously rather than looked up once.
Three steps, one instrument. Start with the free look at your own address.
A parcel-level certificate for your address, built from the federal record: your erosion rate, storm-surge exposure, uncertainty, and whether a licensed site review is warranted.
Assess your addressThe working instrument — live sea state, tide, storm track, radar, and measured change across the eastern-Long-Island reaches. Built for the engineer; open to see.
Enter the consoleYour own coastal instrument — it watches the water, survives the storm, and hands you a sealed, tamper-evident record of exactly what the sea did to your property. We onboard by reach, in order.
Reserve a StationWe set up each Station by hand and onboard one reach at a time. A $250 deposit holds your place and your reach's priority — credited in full toward your Station setup. Tell us who you are and we'll be in touch with the details for your stretch of coast.
