Daly City, CA Coastal Erosion Rate
Is the coast eroding 5.7 miles northwest of Daly City, CA?
Nothing alarming measured 5.7 miles northwest of Daly City, CA: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
The grain of this number
Daly City, CA is the nearest named place, 5.7 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 37.78, -122.51. USGS's California assessment last surveyed this stretch through 1852-2016, 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 4 individual transects averaged together, 0% of which measured erosion rather than growth. Uncertainty on this specific number: 0.8 ft/yr either side. The unadjusted figure here, 0.69 ft/yr, would place it 1061 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS National Shoreline Change data release (ScienceBase, DOI 10.5066/P94J0K7Z), Kratzmann 2024 / Data Report 1187. Rank 1180 nationally for growth belongs to Ocean Park, WA, 604 miles from this stretch, measured at 2.86 ft/yr. 1.8 miles up the coast, Daly City, CA shows the same lack of a significant trend.
