To the Editor:
Folks who concur that sea levels are mounting may possibly find the time period “mean sea level” illogical to involve in a town ordinance.
The facts sheets for geodetic markers utilised in surveying really do not use that term, but in its place use “orthometric peak.” The markers, all around LBI, and their data sheets (in some cases photographs) can be discovered on the web, devoid of a scavenger hunt. Browse just one these facts sheet and you are going to find that the regional geo marker height is not actually measured, but computed and “adjusted.” And hold out until you go through exactly where the most important tidal benchmark is situated: Father Level/Rimouski, Quebec, Canada.
An world wide web search for NAVD1988 will reveal that it will be changed in 2022, and the Woolpert blog mentions its inaccuracy. It‘s practically out of date.
The terms “mean sea level, NAVD1988” don’t belong in a Extensive Seaside Township ordinance. They provide only to kick sand in readers’ eyes.
