Why Are There No Basements in Phoenix?

I have an aunt and uncle back home who spend every summer "down cellar," which in Ohio means that in June, when the temperatures soar into the 80s, they pretty much abandon their three-story house and retreat into their basement until late August, when their "hot" weather ceases.

I envy them. Not because I have a secret desire to live like a vole but because, by this time each year, I am (like so many of us), looking everywhere for a cool place to park myself that won't result in an outrageous electricity bill a few weeks later. And let's face it: Pretty much no one in Phoenix has a basement.

I do, but mine's the type that's referred to as "unfinished," which means that it has 61/2-foot ceilings and is open to the crawlspace under my house, which was built in the 1920s by a transplanted Midwesterner for whom a basement was de rigueur. Even if it were more livable, my basement is so crammed with Rubbermaid tubs full of treasures (I am not a hoarder!) that there's barely room to stand.

Still, having a basement in Phoenix is like owning an ark or having an 11th toe. People always seem astonished. "You have a basement?" is the typical response; and the follow-up comments usually include "What do you do with it?" (I stash tchotchkes there — did I mention that I'm not a hoarder?) and "I wish I had one!" (Me, too — at least, one I could entertain in.)

Which got me to thinking: Why aren't there more basements in our town? I remember hearing that it's because the ground here is too dense here to dig up properly — something about caliche, a sedimentary rock of calcium carbonate that fuses together gravel and sand and pretty much everything it touches — but why is that even an issue? Isn't there, I don't know, some kind of giant machine that's been invented that can blast through stubborn rock and give us a nice cool place to stick a billiard table and a wet bar?

I called Scott McDonald, owner of The Wall Company, a local business that — no kidding — digs basements for new and already existing homes and house plans. I wasn't all that surprised when McDonald explained that our paucity of basements has less to do with hard ground than it does with time and money. What else?

"It's quicker for builders to put up a home without a basement," he explained. "A basement adds about a month to the construction process. And a basement actually costs more to build out here than a second story."

So how come Midwesterners and those living in the East get both? "In colder states, the foundation of a home has to be dug down below the frost line," McDonald told me. "So digging down a couple more feet just isn't that big a deal. But in the desert, we're only required to go about 18 inches down to set the foundation, so digging for a basement is costly and more time-consuming."

Which, I suppose, explains why there's so little underground parking in our city. Think about it: Where better than the desert to tunnel under the endless miles of macadam to install a dark, cool spot to leave one's car? If it were up to me, I'd be living down there.

"Not if you had to pay to dig it all up," according to Brian Gansert, president of operations for the San Diego-based Ace Parking Management, which earlier this month signed a contract to oversee each of the five new and renovated parking structures — one of them underground — attached to downtown's recently revived Phoenix Convention Center.

"Subterranean parking is more costly to build than above-ground structures," Gansert told me. "There's excavation, and then you've got to have a ventilation system installed — lots of money."

If it costs more, we'll never see it — no matter how cool it is. Left to make do without underground parking, I've taken to consulting a website called Parking Carma (www.parkingcarma.com) before I head out. I love the site's snooty attitude ("Finding parking in Phoenix can be impossible!" its splash page bellows) and the icons that tell me whether the lot is wide open, shaded, or — in those rarest of instances — what my family back home would call "down cellar."

I had always wondered why my friends in the desert didn't have basements.  I live in Calgary and everyone has a basement here.  I didn't realize they made the basements because they already had to dig down for the foundation anyways.  That makes sense though.  If I lived in Arizona, I would hire an excavator asap to dig me a basement.  It is too hot there to not have a basement.

We moved to the Phoenix area from Michigan about 4 year ago. No basements in this climate is just plain nuts. So the builders (most of whom know virtually nothing about basic physics, construction materials and engineering) whine about costs and how difficult it is for them to build basements because of the difficult soil conditions - as they put it. But miraculously, builders can find that easy-to-dig-in dirt and dig basement sized holes in the ground for swimming pools, the deep ends of many being much deeper than a regular basement would need to be.

Think how much more comfortable a house in this region would be if it had a basement the same shape as the basic plan footprint. Its not exactly a new idea. For the past few thousand years of inhabiting this desert region, large and small basement-type structures were built; not to store stuff but to help keep structures cool during the heat of the summer.

So...the next time a builder tells you that basements just can't be down this way, tell him or her to think again, do their homework, sharpen their pencils and think "swimming pool" only this time make it the shape of the ground floor plan instead of those curvy kidney shaped holes they regularly and enthusiastically excavate.


I grew up in the rural Midwest, where cellars provided respite from tornados and storage space for our canned vegetables. Ours had a brick floor, grouted with black dirt and, like yours, gave entry to the crawl space, a popular stopover for raccoons and muskrats from the nearby creek. Every now and then we'd spot a rat in the cellar, so it was never a place I fancied escaping to from heat or anything else, although the family cat liked it. What we and most of our neighbors had for summer relief were "summer kitchens," often a separate small building with a stove that would not heat up the house. My dad claimed our SK as his tool room and it looked more like a Smithsonian collection of hammers and saws than an actual active workspace. On hot, muggy days my sibs and I would go out there and fiddle around with his screwdrivers and awls until it got dark and we could head outside to play statue-makers or sing "Wish I may wish I might, see the first star out tonight" and enjoy the coolness.


Cellars? What about Solar Panels? That you don't find it odd that arizona isn't paved with Solar Panels is amazing to me.
