I-35, Brushy Creek and how the city is laid out
Round Rock is divided by I-35, with older neighborhoods and the historic downtown on one side and newer subdivisions spreading out beyond. Road dust and exhaust film settle on the buildings nearest the interstate, and storefronts along the frontage roads show it first. Brushy Creek and its trails bring trees and damp shade to many yards.
Older limestone and brick buildings downtown need a gentler approach than a plain concrete driveway. Pressure that is fine for a slab can pit soft stone or wash mortar out of old joints, so the method gets chosen after looking at what the wall is made of.
