Lavallette, NJ Coastal Erosion Rate
Shoreline change 0.7 miles north of Lavallette, NJ
The coast 0.7 miles north of Lavallette, 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 Lavallette, NJ into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 39.98°N, 74.08°W. USGS's New England / Mid-Atlantic assessment last surveyed this stretch through 2007-2009, computing the rate with its LRR method. Other US regions were surveyed in different years, sometimes decades apart, so this page states its own rather than implying one national vintage.
Where this fits nationally
This reading comes from 22 individual transects averaged together, 0% of which measured erosion rather than growth. The published margin on this reading runs ±0.28 ft/yr. Taken at face value, this segment's raw 0.14 ft/yr reading would land it 884 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 1087 nationally for growth belongs to Sarita, TX, 1598 miles from this stretch, measured at 0.88 ft/yr. Dover Beaches North, NJ, 1.8 miles off, is the adjacent measured stretch, itself no significant trend.
Not this whole stretch, just Lavallette itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
