Prior to performing testing and developing a detailed site plan, existing site conditions should be inventoried and mapped including, but not limited to:
Prior to performing testing and developing a detailed site plan, existing site conditions should be inventoried and mapped including, but not limited to:
−#Surficial geology and underlying stratigraphy;
−#Watercourses (perennial and intermittent), water bodies, wetlands and floodplains;
−#Small headwater drainage features;
−#Topography, slope, and drainage patterns;
−#Existing land cover and land use;
−#Natural heritage conservation areas; and
