What "Bolivar Peninsula" means on this page
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Bolivar Peninsula, TX into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 29.55°N, 94.45°W. Survey years: 2001, method LRR, from USGS's Gulf of Mexico shoreline-change assessment. That's how current the data is here, real, but not a live feed, since a shoreline survey is a major undertaking, not an annual check-in.
25 years at this rate
If 1.75 ft/yr holds for the next 25 years, the coast 8.2 miles northeast of Bolivar Peninsula, TX would retreat roughly 44 more feet, a projection, not a certainty: erosion rates shift with storms, sediment supply and any armoring built in the meantime.
How solid is this number
105 transects feed this segment's number; 100% of them individually measured retreat. Uncertainty on this specific number: 1.32 ft/yr either side.
