Golden Meadow, LA Coastal Erosion Rate
Shoreline change 22.3 miles south of Golden Meadow, LA
The coast 22.3 miles south of Golden Meadow, LA has been retreating at a measured 36.26 feet a year, USGS's own long-term rate for this stretch, built from historical shoreline positions rather than a single survey. At that rate, the shoreline has lost roughly 362.6 feet over the last decade.
What this reading actually covers
This is a roughly 3.5-mile stretch of coast, not one address or parcel - USGS's own transects run every few hundred feet, but that's finer than any one property needs, so this page reports the stretch nearest Golden Meadow, LA. Centered near 29.07°N, 90.37°W. The survey behind it runs to 2001, in USGS's Gulf of Mexico assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
25 years at this rate
If 36.26 ft/yr holds for the next 25 years, the coast 22.3 miles south of Golden Meadow, LA would retreat roughly 907 more feet, a projection, not a certainty: erosion rates shift with storms, sediment supply and any armoring built in the meantime.
