A community grand opening will be scheduled for the spring at Summerrow, an under-construction single-family development at 11966 Manchaca Road, Austin. Development by MileStone Communities, Summerrow began selling lots in May and officially opened its onsite sales office in July. MileStone Communities spokesperson Jared Glazer said the first homes in the community will be finished this spring. Sales and construction for the other lots on the property could continue through 2020, he said.
