19.24.050 - Landscape design and plant requirements.

A landscape documentation package prepared by a licensed landscape architect shall include the following landscape design criteria: A.

Plant Selection and Grouping.

1.

Any plant may be used in the landscape, providing the estimated annual applied water use ("EAWU") does not exceed the maximum annual applied water allowance ("MAWA") and that the plants meet the specifications set forth in items 2—4 below.

2.

Plants having similar water needs shall be grouped together in distinct Hydrozones.

3.

Plants shall be selected appropriately based upon their adaptability to the climate, geologic and topographical conditions of the site. Protection and preservation of existing native species and natural areas is encouraged. The planting of appropriate trees is encouraged.

4.

Minimum Use of Turf. Turf areas shall be used wisely in response to functional needs and shall not exceed the MAWA. Where turf is installed the use of warm season turf is strongly encouraged.

5.

Fire prevention needs shall be addressed in areas that are fire prone. Design should be consistent with regulations from the fire department.

6.

Invasive species of plants should be avoided especially near parks, buffers, greenbelts, water bodies and open spaces because of their potential to cause harm in sensitive areas.

7.

Encourage the appropriate use of mulch within developed landscapes to retain moisture.

8.

Recirculating water systems shall be used for decorative water features.

9.

Where available, recycled water shall be used as the source for water features (excluding swimming pools and spas).

10.

The surface area of a water feature will be included in the MAWA calculation with the evaporation rate equivalent to that of a high water use plant.
