Just make sure you live somewhere between the Museum District and Churc Hill, and make sure you don't have kids.

From experience, as soon as you go north of the interstate (still within Richmond-proper, mind you) things become dramatically less walkable and more auto dependent, and the bus network is sparser. It's still an easy bike ride---for an adult---but don't expect your kids to make that ride with you.
