Corpus Christi, TX Coastal Erosion Rate
Shoreline change 17.2 miles south of Corpus Christi, TX
17.2 miles south of Corpus Christi, TX: USGS's transects didn't pick up a trend here that beats the survey's own uncertainty. That's the majority case nationally, and for this stretch specifically it means the coast is holding, not that the data failed to find anything.
The grain of this number
This is a roughly 3.5-mile stretch of coast, not one address or parcel - USGS's own transects run every few hundred feet, but that's finer than any one property needs, so this page reports the stretch nearest Corpus Christi, TX. Centered near 27.52°N, 97.27°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
13 transects feed this segment's number; 100% of them individually measured retreat. USGS's confidence interval here is ±0.71 ft/yr. Taken at face value, this segment's raw -0.33 ft/yr reading would land it 389 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Rank 995 nationally for growth belongs to Beach Haven, NJ, 1560 miles from this stretch, measured at 0.4 ft/yr. Corpus Christi, TX, 1.9 miles off, is the adjacent measured stretch, itself no significant trend.
