Buras, LA Coastal Erosion Rate
What USGS measures 7.6 miles southwest of Buras, LA
The coast 7.6 miles southwest of Buras, LA shows no statistically significant trend either way. USGS's transects measured a rate here, but it's smaller than the survey's own margin of error for this stretch, so calling it "eroding" or "growing" would overstate what the data actually shows.
What "Buras" 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 Buras, LA into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 29.28°N, 89.62°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.
How solid is this number
18 transects feed this segment's number; 100% of them individually measured retreat. USGS's confidence interval here is ±17.48 ft/yr. Taken at face value, this segment's raw -12.41 ft/yr reading would land it 18 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Rank 942 nationally for growth belongs to Carpinteria, CA, 1779 miles from this stretch, measured at 0.23 ft/yr. 2.2 miles away, Buras, LA is the nearest other measured stretch: also no significant trend.
