The city of Plano has green-lighted a plan to redevelop the city’s old Texas Instruments campus, replacing fields and parking lots with a mix of apartments, restaurants, retail stores and green space. Plano City Council on Tuesday approved a zoning change for the mixed-use Legacy Central development after developers reduced the number of apartment units and set them farther from the US 75 frontage road. The council tabled the proposal in February and asked the developer to make the revisions presented this week. Council members who supported the project expect Legacy Central, located southwest of Legacy Drive and US 75, to attract further redevelopment efforts to Plano’s southeast corridor, where the city has pursued several redevelopment initiatives. “This is a catalyst for the east side, for the central corridor,” Plano Mayor Harry LaRosiliere said. Others were skeptical of the plan to add apartments along US 75. Councilman Ron Kelley said the plan was indicative of a “disturbing trend” in which multifamily units drive major redevelopment efforts in the city. The new apartments, restaurants and green space would be built on land to the east of the former Texas Instruments offices. The offices are sturdily built and would be difficult to tear down, according to developers. Since the council tabled the item last month, developers have worked with city staff to increase the buffer between the apartments and the frontage road by 60 feet. As a result, the number of proposed apartment units on the property dropped from 725 to 695.
