Terrible’s to anchor new San Tan Valley retail development

PHOENIX — A new retail development is planned for one of the Phoenix metro area’s fastest-growing corridors, expected to bring restaurants and shops to a quickly growing area.

Diversified Partners announced plans Thursday for a 3.84-acre retail center at the southeast corner of Bella Vista and Gantzel roads in San Tan Valley. A Terrible’s convenience store and gas station will anchor the project, with space available for yet-to-be-named restaurants, retailers and service providers.

San Tan Valley, which became Arizona’s 92nd municipality in September 2025, has a population of about 100,000, which is projected to surge 27% by 2030.

Within a five-mile radius of the development site, the population exceeds 103,900 residents and is expected to reach 131,500, according to demographic data from Sites USA cited by Diversified Partners.

“The San Tan Valley and Queen Creek markets continue to experience tremendous residential growth, creating strong demand for convenient neighborhood retail,” Walt Brown Jr., founder and CEO of Diversified Partners said in a press release. “This site offers excellent visibility and access in a rapidly expanding trade area.”

The site is next to a 252-unit apartment complex called Rancho Bella Vista, which is currently under construction.

The developer also expects the intersection to see daily traffic of nearly 15,000 vehicles on Bella Vista Road and nearly 20,000 on Gantzel Road.

Diversified Partners has not announced a groundbreaking or opening date.
