What "Port St. Joe" 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 Port St. Joe, FL. Centered near 29.84°N, 85.39°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 0.56 ft/yr accretion rate 5 miles west of Port St. Joe, FL for 25 years would add roughly 14 feet of shoreline, again assuming nothing about the local sediment supply changes.
