Port Aransas, TX Coastal Erosion Rate
Shoreline change 2.4 miles northeast of Port Aransas, TX
Nothing alarming measured 2.4 miles northeast of Port Aransas, TX: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
What this reading actually covers
Port Aransas, TX is the nearest named place, 2.4 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 27.85, -97.06. 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.
Where this fits nationally
72 transects feed this segment's number; 33% of them individually measured retreat. The published margin on this reading runs ±2.28 ft/yr. The unadjusted figure here, 2.22 ft/yr, would place it 1165 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2004-1089. For scale: Barview, OR, 1855 miles away, ranks 1169 of 1211 nationally for growth, 2.33 ft/yr. Port Aransas, TX, 1.7 miles off, is the adjacent measured stretch, itself no significant trend.
