The landscape designer prepares the base map after all the necessary dimensions have been obtained from on-site measuring and other sources. It can also help establish what specific elements need to be removed, replaced, replanted, or relocated later when actual construction begins. Both the base map and the site analysis are necessary in discussing the restrictions and potentials of a site with the clients. First, it records the existing site conditions before new design and construction. Site elements that will be altered or removed are not shown on a base sheet in order to give the designer a “blank slate” for maximum flexibility and creativity. A base map is useful for two reasons.
