Corpus Christi, TX Coastal Erosion Rate
Is the coast eroding 4.6 miles south of Corpus Christi, TX?
The coast 4.6 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 27.69°N, 97.18°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.
Where this fits nationally
Averaging 62 separate transects produced this segment's rate, with 77% individually reading as erosion, rather than relying on any single survey line. The published margin on this reading runs ±0.52 ft/yr. Taken at face value, this segment's raw -0.23 ft/yr reading would land it 463 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Albion, CA sits at national rank 963 for growth (0.3 ft/yr), one reference point among the 1211 scored segments, 1717 miles from here. 2 miles up the coast, Corpus Christi, TX shows the same lack of a significant trend.
