ABSTRACT
Colonial cities typically consisted of residences, streets, open public spaces, and a few businesses, churches, and government buildings. The cities were usually laid out in grids. Savannah, Georgia, based on the grid plan, is a prime example of colonial-era planning. Washington, DC, a notable planning achievement, mixed a grid pattern with radiating diagonal avenues that met circular roundabouts. As settlers moved west, towns like Chicago continued with the grid plan.
