Emergency Location Markers (ELM) on Houston Area Trails

I'm working on the development of a trail in northwest Houston and Harris County. Since it will be remote from street addresses, I'd like to install markers so that, in the event of an incident, a call to 911 can bring emergency services directly to the site. In my travels, I have not seen an emergency location marker on any Houston area trails.

A couple of questions:

Has anyone seen any emergency markers on any area trails? Where?

Has anyone in the area approached trail owners or government entities about emergency location markers? What feedback did you receive?

Does anyone have any experience contacting 911 regarding an incident on a trail in the Houston-Galveston area? What happened?

I have found references to a Dallas system (like the green Dallas sign below) that date back to 2009-2012. Any feedback from the Dallas area on how that is working out?

Other than local systems there is a national system, called "US National Grid" (blue sign below). I'm checking with Harris County 911 to see if they recognize the US National Grid system. If you know of another system, I'd like to find out about it.

Thank you.

The Spring Creek Greenway has mile markers every 1/10 of a mile. These are a three dimensional pyramids with a flat top and the mileage from the trailhead at I-69/US59 riding west.

Yes, mile markers are really nice for routine riding, too.

If you wanted to get really fancy, have not only cumulative distance markers, but those giving the distance to the next road crossing and the name of the road. Sometimes even when you are at a road crossing the name of the road isn't apparent.

A rail trail here exists in three sections across two counties. One has markers every .2 mile that actually make sense (though they count from the original railhead two counties over, not the start of the rideable trail). Another has a handful of markers that really make no sense at all. And the third section has none at all.

Also ironically, there are a few emergency aid callboxes of the old highway variety - but they're typically placed all but within sight of road crossings, rather than in the isolated parts.

The State of NY Department of Enviromental Conservation has a system in place at the Rocky Point conservation area, on Long Island, on its 21 mile mt. bike trail. The trail markers have numbers that reference on file GPS coordinates. Theory is if there’s an emergencey you can cell phone in the trail marker and they know where you are. It’s worked on a number of occasions to rescue injured cyclists, if memory serves.

I’d contact the local mt. bike club - CLIMB, who installed and maintains the trail systems in Long Island.
