Inside Pima County with Rex Scott

In southern Arizona, the shift into heat season is unmistakable. Mornings warm-up earlier, evenings cool down more slowly, and the desert sun begins its months‑long climb toward triple‑digit temperatures. For Pima County, this isn’t just a change in weather—it marks the start of one of our most challenging public‑health periods. This episode of Inside Pima County focuses on how we prepare for that challenge and how residents can protect themselves as the hottest months arrive.
Supervisor Rex Scott is joined by Dr. Theresa “Terry” Cullen, Director of the Pima County Health Department and a leader whose experience spans frontline medicine, national health‑informatics work, global health consulting, and nearly six years guiding one of the county’s largest and most complex departments. Her work is shaped not only by her professional background but by her personal connection to Pima County—her children, husband, and extended family all live here, giving her a deeply rooted commitment to community well‑being.
The Health Department oversees nine divisions that touch nearly every part of daily life: food safety inspections, clinical services, disease prevention, substance‑use response, and more. But one of its most important responsibilities during summer is serving as the convener of Pima County’s heat‑mitigation network. This network includes more than 80 organizations—nonprofits, local governments, universities, and community groups—working together to prevent heat‑related illness and deaths. Weekly meetings throughout the heat season allow partners to coordinate cooling centers, share data, identify gaps in service, and ensure that vulnerable residents are not left behind.
Dr. Cullen explains the risk factors that make some people more susceptible to heat illness: older adults living alone, people on certain medications, individuals with limited access to cooling, outdoor workers, and the unhoused population. Yet she also emphasizes that heat can affect anyone, even lifelong desert residents who think they “know” the climate. Understanding early signs of heat exhaustion, staying hydrated, limiting outdoor activity during peak hours, and checking on neighbors are among the simplest and most effective prevention steps.
Listeners will also learn where to find reliable information about heat advisories, cooling centers, and county resources, including PimaCounty.gov/heat and materials available through public libraries. The episode highlights the importance of community awareness, shared responsibility, and simple acts of care that can save lives.
This introduction sets the stage for a conversation about preparation, prevention, and the power of coordinated community action as Pima County enters another desert summer.

This is the 11th episode of Inside Pima County with Rex Scott, the show where we pull back the curtain on the people and decisions shaping life in our community. Today’s episode features Chris Poirier, Former Director of Development Services.
If you’ve ever replaced a water heater, built a home, or watched a major project rise from the desert floor, the DSD team has been part of that story. Chris joins us to talk about what it really takes to guide development in a county as large and diverse as ours — from everyday residential permits to 600‑acre master plans, from zoning hearings to long‑range planning that will shape the next decade.
We’ll explore how his department balances regulation with customer service, why public participation matters more than people think, and how state laws and voter initiatives shape what local government can and can’t do. Chris also talks about his legacy of 25 years at Pima County and reflects on what he’s learned about community, collaboration, and human nature along the way.

In this episode of Inside Pima County with Rex Scott, Supervisor Rex Scott sits down with Diane Frisch, Director of Pima County’s Attractions and Tourism Department, to explore how tourism plays a vital role in our local economy and quality of life.
Diane shares her unique path from managing radio and TV stations to leading the County’s efforts in promoting attractions, events, and tourism assets. With a small but dedicated team, her department manages the Visitor Center, supports County-owned properties, oversees film permitting, and coordinates events and partnerships across the region—all while working closely with organizations like Visit Tucson.
The conversation highlights just how significant tourism is to Pima County. The industry supports approximately 24,000 local jobs, brings in over 6 million visitors annually, and generates nearly $3 billion in economic impact. Diane emphasizes that tourism is far more than leisure—it’s a key economic driver that supports hotels, restaurants, cultural institutions, and small businesses throughout the community.
Listeners will also hear how the department helps distribute funding to local attractions and events, ensuring taxpayer dollars are invested in organizations that are sustainable, impactful, and aligned with the region’s character. Looking ahead, Diane discusses efforts to attract new events—especially in growing areas like cycling and indoor summer activities—while staying true to Pima County’s culture and heritage.
The episode also touches on Tucson’s designation as the first UNESCO City of Gastronomy in the United States, a recognition rooted in the region’s deep agricultural history, food traditions, and community pride.
From signature events like the Gem and Mineral Show, Rodeo, and Tucson Festival of Books to emerging opportunities at venues like the Mosaic Quarter and the County’s new velodrome, Pima County continues to expand its role as a destination for visitors and a source of pride for residents.
As Diane notes, whether it’s outdoor recreation, festivals, arts, or food, Pima County offers something for everyone—and her team is working every day to make sure people know it.

In this episode of Inside Pima County, Supervisor Rex Scott sits down with Eric Schepp, Director of the Pima County Regional Flood Control District, to explore how the County manages flood risk, protects communities, and is rethinking water as a long-term resource.
Schepp shares his path from civil engineering studies at Johns Hopkins University to a 30-year career with Pima County, highlighting his early work as a hydrologist and eventual rise to district leadership. His passion for the region—and its unique desert environment—shapes his approach to flood control and water management.
The conversation explains the Flood Control District’s core mission: protecting people and property through both structural solutions—like levees, detention basins, and bank protection—and non-structural approaches, including regulations, floodplain management, and land acquisition. These strategies are especially critical in older parts of Tucson, where development predated modern floodplain regulations and solutions are more complex.
Schepp outlines how the District operates as a special taxing district and works across a vast 9,200-square-mile region, partnering with jurisdictions like Marana and Oro Valley to guide smarter development and reduce flood risk. He also discusses federal and state frameworks like the National Flood Insurance Program, noting that Pima County’s high rating earns residents significant flood insurance discounts—up to 40%.
Beyond flood protection, the episode highlights a growing shift: treating stormwater as a valuable resource rather than a nuisance. Innovative projects like the Kino Environmental Restoration Project demonstrate how stormwater and reclaimed water can irrigate public spaces, while pilot efforts such as the Rillito Creek recharge project explore ways to capture and store water underground for long-term use.
Schepp also discusses the County’s Water Working Group, which brings together departments and regional partners to address water sustainability, conservation, and future supply challenges—particularly in areas reliant on private wells.
The episode concludes with a look at newer, community-focused solutions like stormwater parks. These smaller-scale projects reduce localized flooding while providing green space, improving water quality, supporting urban tree growth, and even creating educational and workforce development opportunities for local students.
Overall, the discussion underscores how flood control in Pima County is evolving—balancing public safety, environmental stewardship, and innovative water management to build a more resilient future.

In this episode of Inside Pima County, Supervisor Rex Scott sits down with Pima County Public Library Director Tess Mayer to discuss her background, the role of libraries in the community, and the future of the library system. Mayer shares her journey from teaching English as a second language to a career in librarianship, shaped by her belief that access to information can transform lives. Her experience working in major library systems in Seattle and Berkeley helped shape her focus on equity, outreach, and breaking down barriers to access—values that drew her to Pima County.
Mayer highlights the scope and impact of the Pima County Public Library system, which includes 27 locations, approximately 500 employees, and around three million in-person visits annually, in addition to robust online usage. She emphasizes that modern libraries go far beyond books, offering a wide range of services including e-books, streaming content, online classes, workforce development programs, and community programming. Many of these digital resources remain underutilized, making outreach and awareness a key priority.
The conversation underscores the library’s role as a community hub that supports lifelong learning, literacy, and connection. Traditional offerings like storytimes and book groups remain central, but Mayer also points to innovative programming—from live performances to unique learning experiences—that reflect the evolving needs and interests of the community. She also highlights nontraditional items available for checkout, such as health equipment and Culture Passes that provide free access to local museums, expanding access to education and enrichment opportunities.
Looking ahead, Mayer identifies several priorities, including modernizing outdated materials-handling technology to improve efficiency, safety, and user experience. She also discusses ongoing and future capital projects, such as the new Mission Library and the long-term planning for a new main library, both of which will be shaped by community input. Expanding library hours and improving equitable access across the county are also key goals, particularly for working families and underserved areas.
The discussion also touches on the connection between libraries and broader County initiatives, including early childhood education scholarships funded through the library district. Mayer emphasizes that supporting literacy and early education are complementary—not competing—priorities, both essential to community well-being.
Finally, Mayer highlights the critical role of community partners like the Friends of the Library and the Library Foundation, which provide funding and volunteer support for programs and services. She closes by reinforcing the idea that libraries are foundational to democracy—providing free and open access to information, supporting civic engagement, and ensuring that all residents have the opportunity to learn, grow, and participate fully in their community.
Overall, the episode presents the Pima County Public Library system as a dynamic, evolving resource—one that continues to adapt to meet the needs of a diverse and growing community while staying grounded in its core mission of access, literacy, and lifelong learning.
