A 1.3-acre vacant lot on San Jacinto Place in West Plano is about to get a new neighbor: a 56,876-square-foot, two-story medical and general office building expected to bring 10 employees to the site once construction wraps up. Plano's Planning and Zoning Commission approved the site plan last Monday, clearing the way for development on a parcel tucked into one of the city's busiest outpatient medical clusters.
The approval, first reported by Community Impact, covers a lot near Preston Road that has sat empty within an area already dense with specialty healthcare practices. The site plan was developed by Spiars Engineering, Inc., a Plano-based civil engineering and surveying firm. According to background compiled by Zabalist, the firm, founded in 2000 and headquartered on Custer Road in Plano, has designed more than 20 recorded commercial and site projects across Texas worth roughly $198 million.
Once built, the new office will add 68 additional parking spaces, per the site plan cited by the same account. The project fills a gap in what is already a tightly packed medical corridor: the San Jacinto Place cul-de-sac is home to practices including 1 CP Place pediatric neurology, Dr. Rizvi Wound Care, and Texas Behavioral Health Systems, according to 1 CP Place.
A Corridor Built Around Major Medical Anchors
The new building's location places it near two of West Plano's largest institutional healthcare anchors, Children's Medical Center at Legacy and Texas Health Presbyterian Hospital Plano, according to a commercial listing tracked by LoopNet. That proximity to pediatric and acute care facilities is seen as a driver of patient volume for smaller outpatient practices along the corridor.
The hospital itself is in the middle of a major expansion. Texas Health Presbyterian Hospital Plano, located at 6200 W. Parker Road, launched a $343 million campus expansion in November 2024 that includes a new 300,000-square-foot, eight-story bed tower designed to push capacity to nearly 400 acute and critical care beds, according to Texas Health Resources. The hospital operates as a major Level II trauma center for North Texas.
Traffic and Income Data Explain the Appeal
Commercial real estate data help explain why developers keep targeting this stretch of West Plano. The adjacent Preston Road corridor handles approximately 38,000 vehicles daily and sits within an area with a 1-mile median household income topping $123,000, according to tracking data from Crexi. High household incomes paired with heavy daily traffic have made the area a consistent draw for private medical practices.
Plano's Planning and Zoning Commission, the eight-member appointed body that reviews site plans, plats, and zoning modifications, issued the approval as part of its regular public meeting process. Commissioners are Plano residents appointed by the City Council to two-year terms, according to the City of Plano.
Growth Citywide, Even as School Enrollment Shifts
The approval lands against a backdrop of steady regional growth. Plano's total population reached 301,320 as of January 1, the first time the city has topped 300,000 residents, according to estimates from the North Central Texas Council of Governments cited by the City of Plano. That milestone puts Plano as the ninth-largest city in Texas amid continued regional suburban expansion.
Collin County as a whole has grown even faster, expanding 60.4% between 2010 and 2025, from 782,341 to more than 1.25 million residents, according to Plano Economic Development records. Yet growth hasn't been uniform across every institution: shifting intra-city family demographics led Plano ISD to close two middle schools and two elementary schools for the 2025–2026 school year, per Wikipedia, even as the aging population drives more demand for healthcare services like those clustering on San Jacinto Place.
Plano isn't alone in chasing this kind of commercial growth. Neighboring Collin County suburbs including Prosper and Celina are actively developing along tollway extensions to compete with Plano for high-wage corporate, life-science, and medical office tenants, a dynamic Hoodline previously reported on in the broader race for North Texas commercial tax base. It remains unclear when construction on the San Jacinto Place project will break ground or which medical groups will ultimately occupy the two-story building.
