Quintana, TX Coastal Erosion Rate
Shoreline change 1.5 miles west of Quintana, TX
1.5 miles west of Quintana, 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.
What "Quintana" means on this page
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 Quintana, TX. Centered near 28.91°N, 95.36°W. The survey behind it runs to 2001, in USGS's Gulf of Mexico assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
Where this fits nationally
99 transects feed this segment's number; 0% of them individually measured retreat. The published margin on this reading runs ±7.01 ft/yr. Taken at face value, this segment's raw 5.04 ft/yr reading would land it 1199 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. For scale: Mexico Beach, FL, 602 miles away, ranks 1142 of 1211 nationally for growth, 1.54 ft/yr. 2 miles up the coast, Quintana, TX shows the same lack of a significant trend.
