Homebuilder eyes 6,000 acres south of TSMC for master-planned project Article originally posted on AZ Central on October 8, 2024 A homebuilder is eyeing more than 6,000 acres of Arizona State Land Trust land directly south of Taiwan Semiconductor Manufacturing Co.’s plant for a master-planned project that could include nearly 20,000 residential units, including single-family homes and apartments. PulteGroup, a Georgia-based homebuilder with projects around the Valley, submitted plans to Phoenix for a 6,355-acre master-planned development called NorthPark. The site is west of Interstate 17 and south of Loop 303, directly south of Loop 303 from TSMC’s massive campus. The land is held by the Arizona State Land Department and would need to be sold at public auction before any development could happen. So far, no auction has been scheduled for the site. The proposal also must be voted on by the Phoenix City Council through the public hearing process. So far, no public hearings have been announced for the plan. According to documents submitted to the city, the developer is requesting to have a maximum of 19,247 dwelling units on the site, ranging from single-family homes to high-density apartments. “This diversity will encourage more opportunities for housing affordability and attainability,” the application says in part. “Diversity of housing types also facilitates more dynamic neighborhoods and allows residents to transition between different housing types, depending on their stage-of-life needs, while remaining in their communities.” Employment, housing among largest plans The proposal divides the site in to six “master development parcels” with a variety of land uses in each. The parcel closest to TSMC, directly south of the campus, and the two adjacent parcels include the “innovation corridor,” which could include employment, manufacturing and regional commerce. Residential units would not be permitted in the innovation corridor, which would comprise about 526 acres. “The employment potential of the NorthPark property is massive, enabled by the recent development of the TSMC campus and forthcoming buildout of the Sonoran Oasis Tech Park to the north,” the application submitted to the city says. About 445 acres of the site would be designated “community core,” which would commercial uses like office and mixed-use developments, higher density housing, medical facilities, hotels, restaurants and retail. The plans also call for “neighborhood village” areas that will include medium and higher density housing, like single-family rentals, townhomes, condominiums and traditional apartments. According to the proposal, the neighborhood village designation would take about 405 acres. The largest portion, 2,884 acres, will be designated “traditional neighborhood,” which will focus on lower density housing, primarily traditional single-family homes, but would allow medium-density development, like attached townhomes and lower density apartments. The plan also calls for preserving 2,095 acres of the site as natural open space. Trailheads, paths and access areas could be built within the natural open space areas. The site plan does not designate any specific site for a resort, but the application states that a resort would be a permitted use in several of the development areas. Even more acres in play than for TSMC The 6,355 acres included in the proposal makes NorthPark even larger than the 3,500-acre site that was rezoned to allow TSMC’s facility. That site, called the Sonoran Oasis Science and Technology Park, included the roughly 1,100 acres that was sold to TSMC, and another roughly 2,400 acres that was purchased by Mack Real Estate Group to build complementary and ancillary development adjacent to TSMC’s campus.
