Understanding Tucson's geography
Why Tucson's drive times defy radius math.
Mountain ranges clip two or three quadrants of isochrones for sites near the edges of the valley — an east-side site near Tanque Verde Road sees its isochrone cut sharply by the Rincon Mountains within 8 miles, while a northwest site near Ina Road has open desert access toward Marana and Avra Valley for many more miles. Oracle Road (US-89) north through Oro Valley and Marana is the metro's highest-growth corridor, with rapid residential development and strong retail demand.
The Foothills area along Ina Road and La Cholla Boulevard in northwest Tucson captures the highest household incomes in the metro and is significantly underserved by premium QSR and service brands. Marana along I-10 north of the Tucson city limits is experiencing explosive master-planned community growth and represents the strongest new-market franchise opportunity in southern Arizona.
