   A.   For the efficient use of water, grading of a landscape project site shall be designed to minimize soil erosion, runoff, and water waste. Finished grading configuration of the landscape area, including pads, slopes, drainage, post-construction erosion control, and stormwater control Best Management Practices, as applicable, shall be shown on the Landscape Design Plan unless this information is fully included in separate Grading Plans for the project, or unless the project is limited to replacement planting and/or irrigation to rehabilitate an existing landscape area.

      •   Drainage patterns;
      •   Pad elevations;

      •   Avoid disruption of natural drainage patterns and undisturbed soil; and
      •   Avoid soil compaction in landscape areas.
   D.   The Grading Design Plan shall contain the following statement: “I have complied with the criteria of the ordinance and applied them accordingly for the efficient use of water in the grading design plan” and shall bear the signature of the landscape professional, as required by law.
