Golden Meadow, LA Coastal Erosion Rate
Shoreline change 24.1 miles southwest of Golden Meadow, LA
24.1 miles southwest of Golden Meadow, LA: USGS's transects didn't pick up a trend here that beats the survey's own uncertainty. That's the majority case nationally, and for this stretch specifically it means the coast is holding, not that the data failed to find anything.
The grain of this number
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 29.08°N, 90.46°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.
How solid is this number
This reading comes from 50 individual transects averaged together, 28% of which measured erosion rather than growth. The published margin on this reading runs ±9.21 ft/yr. Taken at face value, this segment's raw 2.21 ft/yr reading would land it 1164 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Mexico Beach, FL sits at national rank 1142 for growth (1.54 ft/yr), one reference point among the 1211 scored segments, 309 miles from here. 1.4 miles up the coast, Golden Meadow, LA shows the same lack of a significant trend.
