Seadrift, TX Coastal Erosion Rate
Is the coast eroding 13.2 miles southeast of Seadrift, TX?
Unusual good news for this stretch: the shoreline 13.2 miles southeast of Seadrift, TX has grown by a measured 1.79 feet a year on average, per USGS's long-term transect data for this section. At that rate, the shoreline has gained roughly 17.9 feet over the last decade.
The grain of this number
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 Seadrift, TX. Centered near 28.29°N, 96.55°W. 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.
25 years at this rate
Holding the 1.79 ft/yr accretion rate 13.2 miles southeast of Seadrift, TX for 25 years would add roughly 45 feet of shoreline, again assuming nothing about the local sediment supply changes.
