Pensacola Station, FL Coastal Erosion Rate
Shoreline change 8.2 miles west of Pensacola Station, FL
8.2 miles west of Pensacola Station, FL: 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 this reading actually covers
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 Pensacola Station, FL. Centered near 30.32°N, 87.45°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.
How solid is this number
Averaging 97 separate transects produced this segment's rate, with 12% individually reading as erosion, rather than relying on any single survey line. USGS's confidence interval here is ±0.31 ft/yr. Taken at face value, this segment's raw 0.17 ft/yr reading would land it 899 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Rank 1067 nationally for growth belongs to Port St. Joe, FL, 138 miles from this stretch, measured at 0.73 ft/yr. 1.8 miles up the coast, Pensacola Station, FL shows the same lack of a significant trend.
Not this whole stretch, just Pensacola Station itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
