The Tucson Neighborhood Built to Use Half the Water
Civano was built to beat the 1995 energy code by 50% and cut potable water 65%. Southeast Tucson's design experiment, and what its homes cost now.
Most subdivisions are sold on a lifestyle. This one was sold on a number — and then somebody went back and checked whether the number was real.
Almost no subdivision in America has to prove anything after it is built. Civano did. The neighborhood off Houghton Road in southeast Tucson was constructed to a written performance target — half the energy of the prevailing code, two-thirds less potable water — and then measured against ordinary Tucson homes to see whether the target survived contact with actual residents. Some of the result is legible from the sidewalk: narrow streets that hold shade, front porches where a garage door would normally face the curb, and gravel-and-desert-plant yards where a conventional development would have laid turf.

A Solar Village That Drew One Bid
The idea predates the houses by two decades. After the 1970s oil shocks, Arizona floated a "solar village" on state trust land southeast of Tucson — a full-scale test of whether desert housing could be built to a resource budget instead of a market default. The Arizona State Land Department committed 818 acres to it. When the parcel finally went to auction in July 1996, one bidder showed up: Community of Civano LLC, which paid the $2.6 million minimum asking price. The Arizona Energy Office had put $300,000 of oil-overcharge funds into a builder program and a sustainable design plan book, so the builders who arrived had a technical manual rather than a slogan to work from. The community held its grand opening in 1999.
The Standard Was the Product
Most master-planned communities sell a lifestyle and let the building code set the floor. Civano inverted that. In 1998 the project adopted the Sustainable Energy Standard for the design and construction of every building on the site: 50 percent less energy than the 1995 Model Energy Code, and 65 percent less potable water. That requirement drove construction methods you will not find in a typical Tucson subdivision — adobe, straw bale, RASTRA block made from recycled polystyrene, and slurry cement panel block, all of which move heat through a wall differently than stick framing does. The same year, the federal Partnership for Advancing Technology in Housing named Civano one of five national pilot developments, citing both its technologies and its approach to land planning. The standard was written for one subdivision and is still published as a Tucson and Pima County energy document.
What You Can See From the Sidewalk
The town plan came out of design charrettes drawing on Andres Duany, Stefanos Polyzoides and William McDonough, with Wayne Moody, Duany Plater-Zyberk & Company and Moule & Polyzoides doing the planning work. The New Urbanist grammar is all there: narrow streets that stay shaded longer, houses pushed toward the sidewalk, and a mixed-use neighborhood center standing where a gated entry monument would normally go. The Congress for the New Urbanism counts 645 living spaces on 345 acres, plus public space ranging from tot lots to a two-acre park, an extensive walking-trail network and preserved open desert. In 2022 — twenty-three years after the grand opening — Moule & Polyzoides won a CNU Charter Award for Civano in the Neighborhood, District and Corridor category.
- The Neighborhood Center (One acre, Landscaped plaza, Mixed use): A one-acre center with a landscaped plaza, built from alternative materials with its own solar and water-conservation systems — and constructed before the houses rather than after them.
- The Shared Amenities (Two pools, Tennis & pickleball, 48 garden plots): Two community swimming pools, tennis and pickleball courts, a shaded tot-lot playground, and a 48-plot community garden where residents plant citrus and herbs.
- Civano Nursery (5301 S. Houghton Rd., Native stock, Xeriscape classes): Founded by the Shipley family at the Houghton Road and Seven Generations Boulevard entrance, selling native and near-native plants and running desert-gardening and xeriscape workshops.
The Water Math, and What It Costs
Xeriscape landscaping is required here, which removes the largest single residential water draw in Tucson before a homeowner makes any choice at all. Beyond that, a home could tie into the reclaimed-water system or take corrugated-metal rainwater cisterns instead — a distinction that matters most in late July, when the monsoon does the collecting. Al Nichols Engineering, which compared the neighborhood against Tucson averages, put total potable water use roughly 56 percent lower. On price, Civano runs above the citywide line: Redfin put the neighborhood's median sale price at $460,000, up about 8 percent year over year, while Homes.com showed a June 2026 median list price near $449,000, down about 7 percent, at a median 64 days on market. Redfin's citywide Tucson median was near $320,000, and Zillow's average home value for the surrounding 85747 ZIP was $365,446, down about 1.8 percent. None of this is investment advice.
Quick reference (July 28, 2026): Civano is a New Urbanist neighborhood off Houghton Road in southeast Tucson, ZIP 85747, roughly 15 miles from downtown. It began as the state's Tucson Solar Village concept on 818 acres of trust land, sold at a July 1996 auction for a $2.6 million minimum bid, and opened in 1999. Its 1998 Sustainable Energy Standard required 50 percent less energy than the 1995 Model Energy Code and 65 percent less potable water; monitoring by Al Nichols Engineering later found potable water use about 56 percent below Tucson homes. Prices, HOA terms and amenity operations change — confirm current details before relying on any single figure.
The Takeaway
If you are shopping southeast Tucson, drive Civano near dawn or dusk, when the narrow streets do the thing they were drawn to do. Then ask two questions that vary lot by lot, because the neighborhood was built by several builders working from the same manual: what the exterior walls are actually made of, and whether that specific house is plumbed to the reclaimed-water system or set up with cisterns. Both answers change the operating cost of the address, and neither one shows up in a listing photo. Thirty years after a single bidder turned up at the auction, the constraints are the amenity.
