TrigpointingUK

Hi!

While out geocaching recently I ended up finding some EABM benchmarks. From what I understand, these are Environment Agency Bench Marks and are left by the Environment Agency to replace destroyed OS trigs and are used to monitor Waste and Refurbishing projects.

I would like to know if anyone knows where I would be able to find a database with these benchmarks so that I can monitor my progress finding them. Also, if Teasel is reading this, It would be great if these were put into your database.

Thanks!

James

Hi James,

While out geocaching recently I ended up finding some EABM benchmarks. From what I understand, these are Environment Agency Bench Marks and are left by the Environment Agency to replace destroyed OS trigs and are used to monitor Waste and Refurbishing projects.

I agree that EABM denotes 'Environment Agency Bech Mark' and have often seen these on features such as drains, sluices and bridges.
However, as far as I know, they aren't generally placed as replacements for OS trig marks.

I would like to know if anyone knows where I would be able to find a database with these benchmarks so that I can monitor my progress finding them. Also, if Teasel is reading this, It would be great if these were put into your database.

There has been an occasional mention of EABM bolts on trigonomy but, from a quick trawl, I can't find anything relevant.
Don't know of a database, sorry. If you decide to compile your own list, I can send you details for a few that
I can recall seeing (mostly in West Yorkshire).

In my view, for what its worth, EABM marks are separate from OS trigs and therefore don't really belong on TrigpointingUK

Is there anything on the £Environment Agency website?

Probably not but maybe they could provide a list.
