Port O'Connor, TX Coastal Erosion Rate

Shoreline change 4.6 miles east of Port O'Connor, TX

No significant trend

Nothing alarming measured 4.6 miles east of Port O'Connor, 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 "Port O'Connor" means on this page

Port O'Connor, TX is the nearest named place, 4.6 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: 28.44, -96.34. 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.

How solid is this number

75 transects feed this segment's number; 61% of them individually measured retreat. Uncertainty on this specific number: 2.68 ft/yr either side. The unadjusted figure here, -1.45 ft/yr, would place it 162 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. Rank 1180 nationally for growth belongs to Ocean Park, WA, 1947 miles from this stretch, measured at 2.86 ft/yr. Port O'Connor, TX, 1.8 miles off, is the adjacent measured stretch, reading severe erosion at 3.29 ft/yr.
