Marietta is the county seat of Cobb County and one of Atlanta's largest suburbs, with a housing stock that ranges from antebellum-era properties near Marietta Square to East Cobb subdivisions built from the 1960s through the 1990s. East Cobb is an unincorporated area where most residents carry a Marietta address, and it contains a dense concentration of swim-tennis subdivisions with aging asphalt driveways and shared parking areas. The city's commercial corridors along Cobb Parkway, Barrett Parkway, and Roswell Road carry heavy traffic from retail, medical, and industrial users, creating significant demand for commercial parking lot paving and repair. Kennesaw Mountain National Battlefield Park borders the western edge of the city, and properties in that area often have wooded lots with drainage and root conditions similar to those found in North Georgia's more rural markets.
