Laguna Heights, TX Coastal Erosion Rate
Shoreline change 9.8 miles southeast of Laguna Heights, TX
Good news, and an honest one: USGS's data can't distinguish this stretch, 9.8 miles southeast of Laguna Heights, TX, from a flat trend. Whatever small movement it measured here is statistical noise, not a reliable direction, so none is claimed.
The grain of this number
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 Laguna Heights, TX, rather than showing one arbitrary line. Segment center: 25.97, -97.17. 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.
What backs this reading up
49 transects feed this segment's number; 27% of them individually measured retreat. The published margin on this reading runs ±7.11 ft/yr. The unadjusted figure here, 0.81 ft/yr, would place it 1079 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 1058 nationally for growth belongs to Dunes City, OR, 1952 miles from this stretch, measured at 0.67 ft/yr. 2.4 miles away, Laguna Heights, TX is the nearest other measured stretch: also no significant trend.
