Tierra Grande, TX Coastal Erosion Rate
Shoreline change 26 miles southeast of Tierra Grande, TX
Nothing alarming measured 26 miles southeast of Tierra Grande, TX: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
What "Tierra Grande" means on this page
Tierra Grande, TX is the nearest named place, 26 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 27.39, -97.33. USGS's Gulf of Mexico assessment last surveyed this stretch through 2001, computing the rate with its LRR method. Other US regions were surveyed in different years, sometimes decades apart, so this page states its own rather than implying one national vintage.
How solid is this number
This reading comes from 83 individual transects averaged together, 0% of which measured erosion rather than growth. USGS's confidence interval here is ±0.51 ft/yr. The unadjusted figure here, 0.17 ft/yr, would place it 901 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2004-1089. Rank 1147 nationally for growth belongs to Coronado, CA, 1239 miles from this stretch, measured at 1.69 ft/yr. Corpus Christi, TX, 1.8 miles off, is the adjacent measured stretch, itself no significant trend.
