Chapter 5 The Design Process The steps in the process include site analysis, concept planning, and planting plan develop- Sir® ment. This guide offers only an overview of these steps and focuses on aspects that relate to 4 _ - native planting design. There are many books on planting design that explore the design - process in more detail. (See References and Resources) Analyzing the site �. � Site analysis, the first step in the design process, involves thoroughly studying the physical WL ^�� - -�_ Y p g p g Y Y g p Y characteristics of the project site. The information that is gathered will be very useful in ' selecting appropriate species for the project. Elements that should be investigated include: • Geology (bedrock characteristics and depth, surficialgeology) • Soils (texture, drainage, pH, soil profile) �• • Landform (topography, aspect) 6�q . ® � .3 = Hydrology (water bodies, surface flow, subsurface flow, depth to water table, impervious surfaces) Vegetation (presettlement vegetation, existing vegetation, presence of invasive 11 exotic species, presence of high-quality habit remnants) " Wildlife (common megafauna and microfauna, endangered/protected animal ,a species, pest species) ' e, microclimate conditions)Climate (wind direction, sunlight, temperature ran g p g Cultural context (land use, roads/trails, land ownership/property lines, structures, impact of human use on vegetation and wildlife) � . Site analysis includes walking the site while observing features, taking measurements and t notes, and using resources such as soil survey books, historical vegetation maps, U.S. - Geological Survey maps and County Biological Survey maps. Observations are recorded to ' e create a basema that is used to develop a concept plan. p p p L-.
