Pakala Village, HI Coastal Erosion Rate
Is the coast eroding 1.2 miles southwest of Pakala Village, HI?
The coast 1.2 miles southwest of Pakala Village, HI 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.
The grain of this number
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Pakala Village, HI into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 21.94°N, 159.66°W. The survey behind it runs to 2007-2010, in USGS's Hawaii assessment, using the WLR 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.
Where this fits nationally
Averaging 257 separate transects produced this segment's rate, with 52% individually reading as erosion, rather than relying on any single survey line. The published margin on this reading runs ±0.26 ft/yr. Taken at face value, this segment's raw -0.02 ft/yr reading would land it 752 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2011-1009. For scale: Bayport, NY, 5074 miles away, ranks 1083 of 1211 nationally for growth, 0.83 ft/yr. 1.9 miles away, Kaumakani, HI is the nearest other measured stretch: also no significant trend.
