Corpus Christi, TX Coastal Erosion Rate
Is the coast eroding 1.9 miles east of Corpus Christi, TX?
The coast 1.9 miles east 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 this reading actually covers
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 27.75°N, 97.14°W. The survey behind it runs to 2001, in USGS's Gulf of Mexico assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
What backs this reading up
126 transects feed this segment's number; 100% of them individually measured retreat. USGS's confidence interval here is ±0.63 ft/yr. Taken at face value, this segment's raw -0.56 ft/yr reading would land it 279 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Fields Landing, CA sits at national rank 1157 for growth (2.04 ft/yr), one reference point among the 1211 scored segments, 1778 miles from here. Corpus Christi, TX, 2.1 miles off, is the adjacent measured stretch, reading slight erosion at 0.74 ft/yr.
