No, not necessarily. Coastal regions change and you may not have a specific reference point to compare to nor remember from 70 years ago. While the sea levels have been rising for the last 10,000 years because we are in an interglacial period and warming, the increase in the rate of the rise (the second derivative) is a concern. Some of it is anthropogenic - how much is still an area of research.

I believe your math is correct, long term:
8.26 inches/70 years = 11.8 inches/century= 147.5 feet 15,000 years from now, which is what I've been posting, consistent with all the paleoclimatologic data over the last 4 million years, AND HAS NOTHING TO DO WITH YOUR SUV!!!!!!. Better pack your swim trunks to see a Broadway show
