When drought tolerant vegetation is required by a city regulation, such as Section 7.6, Landscaping and Screening Regulations, of the UDC, plant selection is from the ADWR Low Water Use/Drought Tolerant Plant List.
Various city landscaping regulations allow the use of seeds within landscape areas. For example, the landscaping and screening regulations allow the use of seeds as a ground cover in lieu of decomposed granite (DG) in such areas as under canopy trees. However, seeds cannot be used to comply with the 50% vegetative coverage area requirements of the street landscape border.
In situations where the use of seeds is permitted, selection of seed material will be from plants on the ADWR Low Water Use/Drought Tolerant Plant List. Also, if the area that is to be reseeded is not within the public right-of-way, seed selection may be in accordance with Section 5-02.3.2, Native Seeds.
All plant material used within the public right-of-way is to be from the ADWR Low Water Use/Drought Tolerant Plant List regardless of whether it is plant or seed material. The only exceptions to this are in the application of native vegetation requirements of the SCZ and the ERZ sections of the UDC.
(Am. Admin. Directive, 11/6/2013)
In projects where seeding is required or is being utilized to meet a landscaping requirement, the items to address, in addition to seed selection, are irrigation requirements,
preparation, and establishment guarantee.
-specific situations will be addressed on a case-by-case basis. General guidelines are provided in this standard; however, alternatives may be proposed to the staff reviewing the landscape plans.
In order to attain the maximum benefit from the seeded materials, it is necessary to till the soil prior to seeding. The method and use of fertilizers, seeding, mulching, tackifiers, etc., will vary per
-specific situations. The applicant is expected to do whatever is necessary to prepare the
to guarantee plant establishment to the satisfaction of the city.
The
that will require revegetation will vary considerably. Some
with little
and with soil textures and structures conducive to capturing rainfall or capable of being modified to capture rainfall can be revegetated on rainfall alone. Some
may require short-term irrigation to achieve plant establishment. The applicant will not be required by the city to irrigate but will, however, be responsible for successful establishment of vegetation using the appropriate seeding/irrigation method.
