Good morning from a Tucson that’s drying out nicely after a week of serious monsoon weather — three swift-water rescues in under half an hour on Monday, a flood watch Wednesday, and then a quick pivot back to sun and temperatures near 97 by the weekend. That’s the desert in mid-September: it can soak you and bake you inside of five days.

What we worked on this week

Where out-of-state buyers actually land in Pima County. Tucson Daily Brief published a data story this week that takes a closer look at who is buying single-family homes here and where they come from. The county's own sales records flag about 36 percent of transactions as involving an out-of-state address — but that flag fires when either the buyer or the seller lives out of state, which mostly captures people leaving. We matched 19,794 single-family sales from January 2025 through August 2026 to the county's parcel file and read each new owner's mailing address directly. The countywide share of buyers whose mail goes out of state: 7.6 percent, not 36. No model computed any of those figures — they come from database queries on the two files.

The gradient across the county is sharp. In Green Valley's 85622, one buyer in four gets their mail out of state and more than half of sales close without a mortgage. On the south side's 85714, one buyer in a hundred is out of state and cash sales are rare. Those two ZIP codes are 25 miles apart. Cash tracks the out-of-state share almost everywhere: in the five ZIP codes with the most out-of-state buyers, the cash share runs from 31 to 54 percent; in the five with the fewest, from 7 to 15 percent. California sent the most out-of-state buyers (218), followed by Washington (200) and Colorado (148) — and the state-by-state breakdown is on our Instagram, which was our most-shared Instagram post to date. Every state sent at least one buyer; the snowbird states cluster in Green Valley and Rancho Vistoso, and their buyers pay cash at least twice as often as buyers countywide.

Who They Are. Also new this week: Tucson Daily Brief launched Who They Are, six org charts covering Pima County, Tucson, Oro Valley, Marana, Congress and the seven Arizona legislative districts that take in Pima County — 98 people in total. Every elected seat shows its term and the next election date, every appointed job shows who holds it and how long they have had it, and every name in our meeting reports now links to that person's page. The point is plain: our What to Watch and What They Decided sections have always told you what was on the agenda and what the board did. This answers the question implied in both section names — who "they" are.

The Oro Valley chart already reflects the November 4 turnover: Mayor Joe Winfield and two council members leaving, Vice Mayor Melanie Barrett moving to the mayor's seat, and three new council members — Rosa Dailey, Rhonda Piña and Matt Wood — taking office. All 21 legislative seats covered by the charts are on the November 3 ballot; the Legislature chart tracks who is retiring, who is termed out, and who lost a primary. The announcement has more on how the charts are built and what comes next.

What's worth knowing

The PFAS cleanup at Davis-Monthan moved on two fronts this week. The Arizona Daily Star reported that the U.S. Air Force offered to begin cleaning up groundwater contaminated with forever chemicals at the base — if Tucson agrees to let a group of Air Force retirees lease city land for a golf course. City Manager Tim Thomure told the council that Tucson's long-term water supply "is in significant danger" without a cleanup; the city has already pulled 24 wells from service and set aside eight more for emergency use only. A separate, private arrangement is also moving: the city announced it is drafting a memorandum of understanding with Warbird National for a remediation system the city says could reach the Central Well Field years faster than the Air Force's current timeline. The city says the MOU will go to Mayor and Council for direction at an upcoming meeting; it is not on this Tuesday's agenda.

Pima County's heat numbers have already passed all of last year's. The county health department reported 123 heat-related deaths and 930 heat-related illness incidents as of early September — already past all of 2025's totals of 117 deaths and 825 illness incidents, with the season not yet over. KOLD reported the county also recorded heat-related deaths in March for the first time, with four that month.

Monday's monsoon storm produced six swift-water rescues across the city, including three in under thirty minutes: a driver pulled from the roof of a car on the south side, a driver swept down Alamo Wash on the east side, and a person swept away near Grant Road and Wyatt Drive. KVOA reported nearly 16,000 Tucson Electric Power customers lost service; a downed power line and toppled tree near Broadway and Kolb forced a closure of Broadway. One driver swept from his car near Alamo Wash was hospitalized. A bystander, John Boehler, anchored a rope for a firefighter during one of the rescues.

Café Français, the eastside bakery that has been a neighborhood fixture for seven years, announced this week that it will close permanently after this weekend. The bakery posted the news on Instagram Wednesday, citing economic uncertainty and rising prices. KOLD reported a sign on the door read "This was neither expected nor planned."

What changed around town

The Pima County Board of Supervisors, at its September 8 meeting, voted 4-1 to tighten rules on economic development non-disclosure agreements, a response to the controversy over Project Blue — the data center proposal the Tucson City Council later voted to reject. The new rules limit how long NDAs can run and require the county to release NDA-related materials in its possession 90 days before any board action is requested. District 4 Supervisor Steve Christy voted against. Tucson Spotlight has the full story.

In Marana, the town council learned at its September 15 meeting that it faces a 14-percent cut to its Colorado River deliveries in 2027 and 2028, and that water staff have been operating as though in a Stage 2 drought without formally declaring one. Staff asked for direction to rewrite the 2023 Drought Preparedness Plan, replacing the Lake Mead elevation trigger — whose underlying federal guidelines expire at the end of 2026 — with a local indicator based on how many years remain before the town must rely on costlier replenishment water. The council also approved a five-year deal to bank 2,364 acre-feet per year with the Cortaro Water Users' Association starting in 2027. The same night, Town Manager Terry Rozema announced Marana's first-ever AAA bond rating. Our full report from the meeting has the details.

Oro Valley's council, meeting September 16, heard that the town missed its sales tax budget by $3.64 million last year, with construction sales tax down 30 percent from the year before. Departments held spending to 92.7 percent of budget, so the general fund balance slipped only about $800,000, to $19.9 million. The council also delayed a decision on a federal grant for Vistoso Trails Nature Preserve to October 7 after Vice Mayor Melanie Barrett raised concerns about encumbering the town's match for multiple years, and in a study session, council members told staff to concentrate annexation work on the Ina and Oracle commercial corridor rather than larger residential areas. Our full report covers the financial results and the annexation conversation in full.

What's opening

Heart Swell Books, at 2700 N. Campbell Ave., picked up a food establishment permit from the county health department this week — the kind of permit a bookshop would need to serve coffee or snacks, and a signal that something is taking shape there, though a health permit typically precedes doors opening by several weeks.

Also new in the permit file: Pei Wei Asian Kitchen applied for a permit at 7252 N. Oracle Rd., and Dickey’s Barbecue Pit is listed at 7077 N. Thornydale Rd. in northwest Tucson. Mountainside Fitness, the Arizona-based gym chain, has a permit listed at 11935 N. Oracle Rd. in Oro Valley — the Class 1 limited food permit is the kind gyms typically hold for a smoothie counter or protein bar station. None of these comes with a confirmed opening date, so consider them early signals rather than announcements.

On the liquor side, Frog & Firkin at 874 E. University Blvd. has applied for a person and location transfer of its bar license, though the city’s planning department has flagged the application as not yet in compliance — building plan approval and a certificate of occupancy are still pending. The application goes before Mayor and Council on September 22. Serial Grillers at 7585 S. Houghton Rd. has also applied for a license transfer and is listed as in compliance.

One thing to watch

The Pima County Board of Supervisors meets Tuesday, September 22, starting at 3 p.m. with a closed study session on the County Administrator search — Jan Lesher retires when her contract ends Jan. 7, 2027 — and then at 5 p.m. for its regular meeting at the Board of Supervisors’ Hearing Room. The big item Tuesday night is a proposed moratorium on data center development throughout unincorporated Pima County, which would halt new projects while the county writes new rules. The same meeting takes up the formal hiring process for a new administrator, a $1 million round of emergency community grants, a 95-acre residential rezoning near Valencia Road that county staff opposes, and authorization to use eminent domain to acquire land for widening Valencia Road between Mission Road and Camino de la Tierra. The Tucson Mayor and Council also meet Tuesday, September 22, with the large water user ordinance — the rules governing data centers and other heavy users — up for a public hearing. If water or land use is on your mind this week, Tuesday is the night to pay attention.
