Resource mapping identifies areas of the site which are optimal for development, or are limited by constraints.
For example, flat areas of land with good aspect and existing access may be ideal to 'cluster' development, whereas gullies or steep slopes may require a more creative design approach in terms of access and architecture. Other development frameworks include infill and brownfield development and mixed use developments. An example of a development framework is shown in Figure 19.
WSD is not a universal solution for land development and there may be instances where a site is too sensitive, or its values are too significant, to suggest development in any way. WSD encourages increased density and mixed use responses within the best development areas, including the retrofit of existing built environments. This preserves a substantial balance area of open space for its values and associated ecosystem services.
