Lamar, TX Coastal Erosion Rate
Shoreline change 14.1 miles east of Lamar, TX
14.1 miles east of Lamar, TX: 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.
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 Lamar, TX. Centered near 28.16°N, 96.76°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
87 transects feed this segment's number; 0% of them individually measured retreat. USGS's confidence interval here is ±1.2 ft/yr. Taken at face value, this segment's raw 0.51 ft/yr reading would land it 1025 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Santa Monica, CA sits at national rank 932 for growth (0.21 ft/yr), one reference point among the 1211 scored segments, 1349 miles from here. 1.9 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.
