Environmental planning forms the basis of all site development decisions and deals with the factors that must be considered before a site plan can be drawn up. The book emphasises the man/nature interface and explains how nature limits and controls what can happen on every piece of land. The text is clearly set out and will help the reader understand exactly what information is needed for a site planning proposal. A new chapter covers the topical subject of sustainable development and uses a live case study to demonstrate how GIS system are now assisting in the design and decision process as communities increasingly participate in local decisions. (Local Agenda 21) Additional line drawings are being added to illustrate key issues addressed in the text.
