My introduction to Landscape Architecture, Design with Nature gives me a sense of the field as being where geology meets the built environment. McHarg’s “ecological planning method” identifies geological features such as slope, drainage, bedrock foundation, et al., for a given region and uses these factors to determine what type of development is appropriate for what land. Although the emphasis is on ecological factors, McHarg also recognizes historic value and leaves room for other social values to be considered in the process.
I found myself frustrated that the process does not address certain planning questions such as how to build communities that promote transit and non-motorized transportation. McHarg allayed these frustrations by repeatedly noting that the ecological method does not generate a plan, it simply lays the environmental basework; other goals can be addressed when the plan is made. Indeed, the method seems a far more sophisticated base than either sprawl or geometric concepts such as greenbelts, wedges, or even spider-web networks.
