I'm not sure about the degree to which it's enforced but the standard speed limit on local streets in Denver and Boulder is 20 mph (ie. if there's no sign telling you the speed limit is something else, that's the speed limit). It was lowered from 25 mph to promote the safety of cyclists and pedestrians.
