Grading design requirements and 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 city permits satisfies this requirement.

1.

The project applicant shall submit a landscape grading plan, for Community Development Director or designee review and approval, 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 remains within property lines and does not drain on to non-permeable hardscapes;

c.

Avoid soil compaction in landscape areas.

b.

Avoid disruption of natural drainage patterns and undisturbed soil; and

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.
