James,
If the location is right, install what looks like access to a septic system. I’d use it for a big cache or a root cellar. Seal the entrance with concrete which can be busted out with a sledge hammer, or perhaps use lumber or brick to cover the walls of the entrance and use the original access for another purpose to hide it’s original intent such as a cache of lesser importance.

Jim,
You wrote: “In particular, ideas on camouflaging the entrance trap door would be appreciated.”
I wasn’t able to clearly visualize the trap door in the garage. But if the trap door is near a wall, or is recessed at or just below the floor level I might cover the area with one of those 1/8 inch thick oil drip catching sheets of metal available at most auto stores, etc.
If I didn’t need regular access to the entry, I would add some Kitty Litter to the metal sheet and perhaps set a push lawn mower on top of that.
A little easily-visible used oil added to the kitty litter for effect would probably help too. – KMA
Sir,
The first thing I would do is make sure this is not an old converted septic tank. If it were I’m sure you would already know that! If it is going to be an occupied shelter: The first thing I would do is to make an emergency exit to the ‘room’. Dig a tunnel from the outside of the garage down to the room about half way up a wall from the yard and fill with sand. About a foot down from the yard hole place pressure treated plywood then dirt then grass. Keep a small axe, a sledge hammer, cold chisel, hack saw with metal cutting blade and a small folding shovel in the room at all times. If you ever get trapped in there you can break the wall out, let the sand fall out in the room, dig some sand out, and escape. You must always have an alternative exit an any situation.
The second thing I would do if its a room is coat the walls, floor, and ceiling at least twice with a waterproof sealer.
The third thing I would do is run a six inch PVC pipe out one wall and have it come out in the yard, screen the yard end and place a large planting pot over it with false bottom with holes in the pot. For heavier safety you could build a cement planter with holes that look like weep holes. Place a false bottom in it, and fill with plants. Inside the room you can add a hand crank squirrel cage blower. [JWR Adds: And a HEPA filter if you want the space top double as a fallout shelter.] You will need to repeat the same for exhaust air. What comes in must go out. Air, water, food goes in and comes out!
The fourth thing I would do is stock it up: water, food, blankets, sleeping bags, guns, ammo, sealable drums for poop bags, first aid and all the goodies.
The fifth thing I would do is start spending nights in it–first one, then two, then three. Make it familiar. You may find you freak out after a few days, and yet it takes weeks for radiation half life to dissipate. Get used to it, you don’t want to do that under stress.
The main entry can be concealed with a lightweight fake shelf made from balsa wood. A metal plate can be hinged, fastened to the floor, covered with a rubber mat, and the light shelf bolted to the metal door from below. You can glue stuff to it to make it look like a used shelf. Rings can be welding to the under side of the metal door so chains can be installed to hold it down to keep the ‘bugs’ out. Just a quick thought. – Jesse
