13.10.120   Grading design plan.
   A.   For the efficient use of water, grading of a project site shall be designed to minimize soil erosion, runoff and water waste. A grading plan shall be submitted as part of the landscape documentation package. A comprehensive grading plan prepared by a civil engineer for other local agency permits satisfies this requirement.
   1.   The project applicant shall submit a landscape grading plan that indicates finished configurations and elevations of the landscape area including:
   a.   Height of graded slopes;
   b.   Drainage patterns;
   c.   Pad elevations;
   d.   Finish grade; and
   e.   Stormwater retention improvements, if applicable.
   2.   To prevent excessive erosion and runoff, it is highly recommended that project applicants:
   a.   Grade so that all irrigation and normal rainfall remain within property lines and do not drain onto non-permeable hardscapes;
   b.   Avoid disruption of natural drainage patterns and undisturbed soil; and
   c.   Avoid soil compaction in landscape areas.
   3.   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 a licensed professional as authorized by law.
