At least it's a slab........around here, utilities/phones/cable in new developments are housed in boxes or short poles. Much harder to disguise :-) How often does one need access to the slab?

Septic drain fields are common in my more rural area and they all have round access lids about 2.5' in diameter. They are typically green and blend into the surrounding lawns almost seamlessly. So one consideration is painting the slab to match/blend into the surrounding lawn :-) Or mulch. Otherwise, some low growing shrubs (dwarf mugo pine, Juniperus procumbens 'Nana', 'Blue Star' juniper, 'Magic Carpet' spirae) or even ornamental grasses and perennials can help to hide the slab.

I like the rock idea as well :-) Rock is wonderful in a garden and is the ultimate in low maintenance landscaping! I might even consider including the slab as part of a dry stream bed with low growing plants or groundcovers bordering. Something like this but on a somewhat smaller scale.

thanks! I'll call the utility company and see about painting it green. I also love the idea of the low shrubs specially evergreens.

Be prepared that the utility company may provide you with a list of limitations of what you can do. They may require so many feet of clearance around this so they have the access required for potential servicing and future upgrades to the infrastructure.

If you can put something on top of it a container garden or cluster of planted graduated pots would be pretty. It could be on a wheeled base for easy moving or fill half way up with Styrofoam peanuts then soil to decrease weight. Or a pot within a pot.

I like the pots in wheeled base idea frankielynnsie!
