Urban planning is not an extension of architecture, but requires the co-ordination of a wide variety of skills and inputs. Most importantly, planning is meaningless unless it is firmly linked to implementation. The planner's best course of action is to set the objectives of his plan, and use these to determine policy initiatives. As events occur, and development takes place, new initiatives may be called for, so that the original objectives continue to be pursued. Without such a process of continuous readjustment, in response to a changing environment, the original objectives stand little chance of being realised. After suggesting how the urban planning process should be conducted, the author concludes with the changes in law that are required.
