(2) Incorporate compost at a rate of at least four cubic yards per 1,000 square feet to a depth of six inches into landscape area (unless contra-indicated by a soil test in which prescribed volumes of compost can be modified as approved by the Director);
(3) Plant material shall comply with all of the following:
(A) for residential areas, install climate adapted plants that require occasional, little or no summer water (average WUCOLS plant factor 0.3) for 75 percent of the plant area excluding edibles and areas using recycled water; for non-residential areas, install climate adapted plants that require occasional, little or no summer water (average WUCOLS plant factor 0.3) for 100 percent of the plant area excluding edibles and areas using recycled water;
(B) a minimum three inch (3 inch) layer of mulch shall be applied on all exposed soil surfaces of planting areas except in turf areas, creeping or rooting groundcovers, or direct seeding applications where mulch is contraindicated. Prescribed depths of mulch and location may be modified as approved by the Director;
(C) to increase carbon sequestration in the unincorporated county, each new single-family residential project shall include two trees per dwelling unit. Trees shall be located on private land outside of the public right-of-way. See the County's Water Efficient Landscape Design Manual for tree planting guidelines and a definition of which single-family residential projects must comply with this requirement.
(4) Irrigated turf shall comply with all of the following:
(A) Turf shall not exceed 25 percent of the landscape area in residential areas, and there shall be no turf in non-residential areas;
(B) Turf shall not be planted on sloped areas which exceed a slope of 1 foot vertical elevation change for every 4 feet of horizontal length;
(C) Turf is prohibited in parkways less than 10 feet wide, unless the parkway is adjacent to a parking strip and used to enter and exit vehicles. Any turf in parkways must be irrigated by sub-surface irrigation or by other technology that creates no overspray or runoff.
(5) Irrigation systems shall comply with the following:
(A) Automatic irrigation controllers are required and must use evapotranspiration or soil moisture sensor data and utilize a rain sensor.
(B) Irrigation controllers shall be of a type which does not lose programming data in the event the primary power source is interrupted.
(C) Pressure regulators shall be installed on the irrigation system to ensure the dynamic pressure of the system is within the manufacturers recommended pressure range.
(D) Manual shut-off valves (such as a gate valve, ball valve, or butterfly valve) shall be installed as close as possible to the point of connection of the water supply.
(E) All irrigation emission devices must meet the requirements set in the ANSI standard, ASABE/ICC 802-2014, "Landscape Irrigation Sprinkler and Emitter Standard." All sprinkler heads installed in the landscape must document a distribution uniformity low quarter of 0.65 or higher using the protocol defined in ASABE/ICC 802-2014.
(F) Areas less than 10 feet in width in any direction shall be irrigated with subsurface irrigation or other means that produces no runoff or overspray.
(6) For non-residential projects with landscape areas of 1,000 square feet or more, a private submeter(s) to measure landscape water use shall be installed. Flow sensors connected to an automatic irrigation controller may also function as a landscape water meter, provided they accurately measure and record water applied to the landscape.
(b) At the time of final inspection, the permit applicant must provide the owner of the property with a certificate of completion, certificate of installation, irrigation schedule and a schedule of landscape and irrigation maintenance.

(a) A person may submit an application to modify the outdoor water use authorization required by this chapter on a form provided by the Director of PDS.
(b) An applicant requesting modification of an authorization where the total landscaped area after modification is greater than 500 square feet but less than 2,500 square feet shall comply with section 86.706.
(c) An applicant requesting modification of an authorization other than the type of project in subsection (b) above, shall comply with sections 86.707 - 86.711.

All projects requiring the issuance of a water use authorization that have installed approved landscaping and irrigation, shall submit to the Director of PDS a Certificate of Completion that contains the following elements:
(a) A Certificate of Completion on a form provided by the Director of PDS within 10 days after installation, verifying that the landscaping and irrigation were installed as allowed in the approved landscape and irrigation plan, that all approved soil amendments were implemented and the installed irrigation system is functioning as designed and approved. The certificate of completion shall be signed under penalty of perjury by the person to whom the water use authorization has been issued and by a California licensed, landscape architect, civil engineer or architect. Where the water use authorization has been issued to a single family homeowner who either hired a licensed landscape contractor to install the landscaping and irrigation, or installed it themselves, the certificate shall be signed under penalty of perjury by the homeowner and the contractor, or by the homeowner if installed by them. Property owners who designed and installed landscape on their own property shall also be required to sign certificates.
(b) For those single family residential projects required to comply with Section 86.709(b)(10) with an approved Landscape Documentation Package, a copy of the developer/homebuilder signed disclosure statement to be provided to each new homeowner about their obligations to design, install, and maintain their landscapes based on the water budgets established for their lot and their obligations to install and maintain two trees for carbon sequestration, as well as, their obligation to install and maintain vegetated structural BMPs or any other vegetated BMP as applicable, shall be provided.
(c) To the extent applicable, a copy of the HOA's Architectural Guidelines (or similar) indicating that all homes are required to be compliant with the Prescriptive Compliance Option guidelines established on the approved Landscape Documentation Package and instructions to homeowners to submit a landscape plan to the County if they so choose to adjust their water budget calculations.
