Corpus Christi, TX Coastal Erosion Rate
Shoreline change 2.8 miles south of Corpus Christi, TX
The coast 2.8 miles south of Corpus Christi, 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 "Corpus Christi" 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 Corpus Christi, TX into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 27.71°N, 97.17°W. 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
Averaging 56 separate transects produced this segment's rate, with 100% individually reading as erosion, rather than relying on any single survey line. USGS's confidence interval here is ±0.75 ft/yr. Taken at face value, this segment's raw -0.42 ft/yr reading would land it 340 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Chincoteague, VA sits at national rank 1210 for growth (11.04 ft/yr), one reference point among the 1211 scored segments, 1442 miles from here. 2 miles up the coast, Corpus Christi, TX shows the same lack of a significant trend.
