St. Pete Beach, FL Coastal Erosion Rate
Shoreline change 1.2 miles southeast of St. Pete Beach, FL
The coast 1.2 miles southeast of St. Pete Beach, FL shows no statistically significant trend either way. USGS's transects measured a rate here, but it's smaller than the survey's own margin of error for this stretch, so calling it "eroding" or "growing" would overstate what the data actually shows.
What "St. Pete Beach" means on this page
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest St. Pete Beach, FL into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 27.70°N, 82.73°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.
How solid is this number
This reading comes from 82 individual transects averaged together, 34% of which measured erosion rather than growth. USGS's confidence interval here is ±0.53 ft/yr. Taken at face value, this segment's raw 0.08 ft/yr reading would land it 834 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: Channel Islands Beach, CA, 2197 miles away, ranks 1106 of 1211 nationally for growth, 0.99 ft/yr. 3.5 miles away, South Pasadena, FL is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just St. Pete Beach itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
