Dear Amy: Who helps create a city? — Maurice, Ashland, Mass.

Dear Maurice: The creation of a city is a collaborative effort by city planners, builders, the local government and the community. Overall, the city planner is responsible for the initial layout or maintenance of the city. Planners are concerned with maximizing space, protecting the environment, organization and efficiency. They pay attention to the number of parks in neighborhoods and how big a parking lot should be for certain businesses. To learn more about city planners and to participate in planning activities of your own, visit www.planning.org/kidsandcommunity.
