Floodplain Reference Marks
Posted 27 February 2012 - 01:21 PM
It turns out these are special Floodplain Reference Marks. The one we found, is 070065 and it was established in 2002 related to Hurricane Allison Recovery.
For anyone interested in any of this, here's some links It's very thorough info for those who might want to chase down these important waypoints. Keep in mind these are active benchmarks and it's against the law to tamper with them in any way. Enjoy.

The thing is these are so new and well documented perhaps finding them isn't as challenging or exciting as uncovering and old disc buried under 12 inches of sod located directly under a muny airport searchlight tower. Still, they are real benchmarks, and I believe they are very suited to being hunted down and logged.
It took quite a bit of digging to find who exactly put the brass disc out that we found quite by accident. The PIDs or datasheets are impeccable - complete with photos and very good descriptions. It's tempting to send the link to the database to ?? for inclusion as I believe these recovered reference marks are Bluebooked based on NOAA/NGS website description.
If nothing else they might be fun to find in your own neighborhood just for grins.

I recently discovered that the San Jacinto Monument is listed as a benchmark.
Speaking of the Baytown Nature Center, there is a benchmark there placed in 1993 called SUNK (lol) that I've tried to find, but couldn't. The description says, "THE STATION IS AN NOS ALUMINUM DISK WITH A BAR MAGNET UNDER ITS CAP AND ATTACHED TO AN ALUMINUM ROD DRIVEN 1.2 M (3.9 FT) INTO THE GROUND AND SURROUNDED BY A ROUND CONCRETE MONUMENT". If it's still there, perhaps if I went out with a metal washer on a string, I could find the magnet.
