         d.   A plan (surface view) showing elevations or contours of the ground, all proposed and existing structures on the site and location; and elevations of all streets, water supply and sanitary facilities;
         e.   Photographs showing existing land uses and vegetation upstream and downstream;
         f.   Information on all soil types;
