Lamar, TX Coastal Erosion Rate
Shoreline change 9.3 miles east of Lamar, TX
The coast 9.3 miles east of Lamar, TX 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 "Lamar" 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 Lamar, TX into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 28.09°N, 96.85°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.
Where this fits nationally
This reading comes from 107 individual transects averaged together, 1% of which measured erosion rather than growth. The published margin on this reading runs ±0.44 ft/yr. Taken at face value, this segment's raw 0.2 ft/yr reading would land it 921 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 963 nationally for growth belongs to Albion, CA, 1719 miles from this stretch, measured at 0.3 ft/yr. 2.3 miles away, Lamar, TX is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just Lamar itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
