A 230-acre stretch of land near Rockride Lane and County Road 110 is about to become one of the largest new residential developments on the Round Rock-Georgetown border. The Starling community will bring 900 single-family homes to the area, with construction slated to begin around September or October, according to a developer representative.
The project, first detailed by Community Impact, is being built by Risewell Homes, which is offering four distinct lot width options ranging from 45-foot to 70-foot homesites, according to Risewell Homes.

That MUD structure allows residents to pay taxes to both the city and the utility district, letting the developer finance infrastructure through tax-exempt bonds…
