The Ashevilles were 225 feet (69 m) long at the waterline and 241 feet 2 inches (73.51 m) long overall.
They had a beam of 41 feet 3 inches (12.57 m) and a draft of 11 feet 4 inches (3.45 m) at a displacement of 1,575 long tons (1,600 t) normally; their full load displacement increased to 1,760 long tons (1,790 t).
The vessels had a flush deck and they were fitted with two masts.
Each vessel had a crew of 159 officers and enlisted men.

Each vessel was powered by one Parsons geared turbine driving a single screw propeller.
Steam for the turbine was provided by three coal-fired Thornycroft Bureau Modified boilers, which were vented into a single funnel located amidships.
The ships' propulsion system was rated at 850 shaft horsepower (630 kW) and provided a top speed of 12 knots (22 km/h; 14 mph).
The ships had a cruising radius of 2,000 nautical miles (3,700 km; 2,300 mi).
Tulsa was one of the last US Navy ships to be given auxiliary sails to supplement her steam engines.
In 1922, Asheville was converted to burn fuel oil in her boilers.

They were armed with three 4-inch (100 mm) 50-caliber guns in single mounts, one on the bow and two at the stern on the centerline.
They also carried a battery of lighter weapons, including two 3-pounder 47 mm (1.9 in) guns, two 1-pounder (37 mm (1.46 in) guns and four .30 Lewis MGs.
Tulsa later had a depth charge rack installed, giving her some manner of anti-submarine capacity.
