Rio Rico is an unincorporated community of about 20,500 people just north of Nogales, at roughly 3,480 feet. Its eastern half climbs into the foothills of the San Cayetano Mountains, and the old ghost town site of Calabasas lies within its boundaries. With nearly 6,900 homes spread over about 63 square miles, many properties sit on open lots with long driveways and natural drainage.
Fire & Water Energy operates as a referral service and is not a restoration company. Phone (866) 937-3230 and we'll try to match you with an independent restoration contractor that works in Rio Rico. Availability depends on local firms, and the referral disclosure explains our role.
Where two desert channels meet
Sonoita Creek runs about 31 miles from near Sonoita past Patagonia and Patagonia Lake, then sinks beneath the sand for several miles before joining the Santa Cruz in Rio Rico. The Santa Cruz itself is a dry bed for much of the year and only flows after significant rain; in September 2014, heavy storms sent it running high and fast.
A federal flood study for neighboring Nogales found that roughly half of the year's rain falls from July through September. Santa Cruz County was included in FEMA's 2000 severe storms and flooding declaration (DR-1347).
Common causes of water damage in Rio Rico houses
Most indoor water losses start with plumbing: a water heater that gives out, a cracked toilet tank, a dishwasher line, or a washing machine hose. During summer storms, wind-driven rain can enter through roofs, windows and doors, and runoff can collect against walls on sloped lots in the foothills.
A typical contractor shuts off the source, removes standing water, measures moisture in floors and framing, and dries the house with commercial dehumidifiers and air movers. Rebuilding should wait until readings confirm the structure is dry. Our pages on emergency water removal and water damage restoration describe that order of work.
Federal disaster declarations that included Santa Cruz County
FEMA records show Santa Cruz County was included in 1 major disaster declarations for weather or fire events from 2000 through 2026 (1 severe storm, by FEMA incident type). Declarations are made at the county level, so they do not mean every neighborhood in Rio Rico was affected. The most recent:
- 2000 – Severe Storms and Flooding (DR-1347)
Source: OpenFEMA Disaster Declarations Summaries, retrieved 2026-10-10. Counts include major disaster (DR) declarations with hurricane, flood, severe storm, tropical storm, fire, tornado, coastal storm, winter or ice storm, mudslide and dam/levee incident types.

Fire and smoke cleanup on open foothill lots
Homes near brush and grassland on the San Cayetano foothills benefit from cleared space around structures, particularly in the dry weeks before summer rains begin. Inside, kitchen fires, space heaters and electrical problems are frequent causes.
After the fire department clears the scene, a reputable company will usually secure the home, remove burned debris, clean soot from walls and contents, dry out firefighting water and deodorize. See fire damage cleanup for an outline of each phase.
Runoff, flooding and storm damage cleanup
Because both the creek and the river are dry most months, it is easy to underestimate how fast they rise once a storm hits upstream. Low crossings, driveways that cross washes, and homes near channel banks deserve extra caution. Strong summer winds can also tear roofing and drop trees.
Floodwater carries soil, debris and possibly sewage, so contractors commonly remove soaked drywall, insulation and flooring, disinfect, and dry before rebuilding. More detail is on flood damage restoration and storm water damage restoration.
Mold prevention when the humid months arrive
The rainy season is also the humid season, and moisture trapped inside walls or under flooring after a leak can lead to mold within a couple of days. Attics under roof leaks and rooms on the uphill side of a sloped lot are spots to check.
Following EPA guidance, small areas under about 10 square feet can often be cleaned by the homeowner wearing gloves and an N95 respirator. Larger growth, mold after floodwater, or a musty smell with no visible source usually calls for mold removal by a professional.
Rio Rico emergency steps
- Call 911 for fire, injury, gas odor or anyone stranded by water.
- Do not cross a running wash or flooded road in a vehicle or on foot.
- Turn off power to wet rooms only from a dry location.
- Close the main water valve when plumbing is leaking.
- Document every damaged room with photos and video for your claim.
- Hold off on tossing ruined belongings until your adjuster has seen them; what is covered depends on your policy, so check with your insurer or agent.

Rio Rico restoration FAQs
Does the Santa Cruz River really flood in Rio Rico?
The river is usually dry, but significant rain can make it run high and fast, as it did in September 2014. Treat the channel and any washes that feed it as dangerous during storms.
Where does Sonoita Creek come from?
It starts near Sonoita, flows past Patagonia and Patagonia Lake, and then disappears into the sand for several miles before meeting the Santa Cruz in Rio Rico. Rain far upstream can still reach the confluence.
When should I prepare my roof and drainage?
Before July. About half of the area's annual rain falls between July and September, so clean gutters, check flashing and grade soil away from the foundation in late spring.
Can I call from Nogales or Green Valley?
Yes. Nogales, Green Valley and other nearby communities can use the same number. Whether an independent contractor can take the job depends on who works in that area.
