Corpus Christi, TX Coastal Erosion Rate

Shoreline change 7.4 miles south of Corpus Christi, TX

Slight erosion

USGS's shoreline-change data puts this stretch, 7.4 miles south of Corpus Christi, TX, at 0.56 feet of erosion a year on average, a long-term rate for this specific ~3.5-mile section, not one storm's damage. At that rate, the shoreline has lost roughly 5.6 feet over the last decade.

What "Corpus Christi" means on this page

USGS surveys the coast in transects spaced a few hundred feet apart; this page groups the nearest ones into a single ~3.5-mile reading for the stretch closest to Corpus Christi, TX, rather than showing one arbitrary line. Segment center: 27.65, -97.21. 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.

What 0.56 ft/yr means over time

Run 7.4 miles south of Corpus Christi, TX's 0.56 ft/yr rate forward 25 years and it implies about 14 feet of further retreat, assuming nothing changes, which is exactly the assumption a seawall or nourishment project exists to break.

Where this fits nationally

Averaging 117 separate transects produced this segment's rate, with 99% individually reading as erosion, rather than relying on any single survey line. The published margin on this reading runs ±0.32 ft/yr. Among the 1211 US coastal segments with a measurable trend, this one ranks 280 for erosion, 1 being the fastest-retreating coast in the dataset. Source: USGS Open-File Report 2004-1089. Rank 116 nationally for erosion belongs to Tiki Island, TX, 178 miles from this stretch, measured at 2.3 ft/yr, 4.1x this stretch's rate. 2.4 miles up the coast, Corpus Christi, TX shows the same lack of a significant trend.

Not this whole stretch, just Corpus Christi itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
