Corpus Christi, TX Coastal Erosion Rate
Is the coast eroding 25 miles south of Corpus Christi, TX?
Nothing alarming measured 25 miles south of Corpus Christi, 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 "Corpus Christi" means on this page
Corpus Christi, TX is the nearest named place, 25 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: 27.42, -97.32. 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.
What backs this reading up
This reading comes from 34 individual transects averaged together, 0% of which measured erosion rather than growth. The published margin on this reading runs ±0.48 ft/yr. The unadjusted figure here, 0.34 ft/yr, would place it 979 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. Camp Pendleton South, CA sits at national rank 1102 for growth (0.98 ft/yr), one reference point among the 1211 scored segments, 1262 miles from here. 1.8 miles away, Tierra Grande, TX is the nearest other measured stretch: also no significant trend.
