Dover Beaches North, NJ Coastal Erosion Rate
Shoreline change 0.8 miles north of Dover Beaches North, NJ
The coast 0.8 miles north of Dover Beaches North, NJ 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 this reading actually covers
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Dover Beaches North, NJ into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 40.00°N, 74.07°W. The survey behind it runs to 2007-2009, in USGS's New England / Mid-Atlantic 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.
What backs this reading up
91 transects feed this segment's number; 56% of them individually measured retreat. The published margin on this reading runs ±0.3 ft/yr. Taken at face value, this segment's raw -0.04 ft/yr reading would land it 727 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2010-1119. Rank 1038 nationally for growth belongs to Sarita, TX, 1597 miles from this stretch, measured at 0.58 ft/yr. 1.8 miles up the coast, Lavallette, NJ shows the same lack of a significant trend.
