<br />(6) soil analysis report, if not submitted with Landscape Documenta-
<br />tion Package, and documentation verifying implementation of soil report
<br />recommendations (see Section 492.5).
<br />(b) The project applicant shall:
<br />(1) submit the signed Certificate of Completion to the local agency for
<br />review;
<br />(2) ensure that copies of the approved Certificate of Completion are
<br />submitted to the local water purveyor and property owner or his or her
<br />designee.
<br />(c) The local agcotey shall:
<br />(1) receive the signed Certificate of Completion from the project appli-

<br />§492.10. Irrigation Scheduling.
<br />(a) For the efficient use of water, all irrigation schedules shall be devel-
<br />oped, managed, and evaluated to utilize the minimum amount ofwater
<br />required to maintain plant health. Irrigation schedules shall meta, the fol-
<br />lowing criteria:
<br />(1) Irrigation scheduling shall be regulated by automatic irrigation
<br />controllers.
<br />(2) Overhead irrigation shall be scheduled between 8:001 p.m. and
<br />10:01 a.m. unless weather conditions prevent it. If allowable hours of ir-
<br />rigalion differ from the local water purveyor, the stricter of the two shall
<br />apply. Opertlion of the irrigation system outside the normal watering
<br />window is allowed for auditing and system maintenance.
<br />(3) For implementation of the irrigation schcdule, particular attention
<br />must be paid to irrigation nm times, emission device, flow rate, and cur-
<br />rent reference evapotranspiration, so that applied water mints the Esti-
<br />mated Total Water Use. Total annual applied water shall be less than or
<br />dual to Maximum Applied Water Allowance (MAWA). Actual irriga-
<br />tion schedules shall be regulated by automatic irrigation controllers using
<br />current reference evapotranspiration data (c.g.. CIMIS) err tion rmuslure
<br />sensor data.
<br />(4) Parameters used to set the automatic controller shall be developed
<br />and submitted for each of the following:
<br />(A) the plant establishment period;
<br />(B) the established landscape; and
<br />(C) temporarily irrigated areas -
<br />(5) Each
<br />reas_(5)'Each irrigation schedule shall consider for each station all of the
<br />following that apply:
<br />(A) irrigation interval (days between irrigation);
<br />(B) irrigation run times (hours or minutes per irrigation event to avoid
<br />nmoff);
<br />(C) number of cycle starts required for each irrigation event to avoid
<br />nmol ,
<br />(D) amount of applied water scheduled to be applied on a monthly ba-
<br />sis;
<br />(E) application rate setting;
<br />(F) root depth setting;
<br />(G) plant type setting;
<br />(II) soil type;
<br />(1) slope factor setting;
<br />(J) shade factor setting; and
<br />(K) irrigation unilixmity or efficiency setting.

<br />§492.11. Landscape and Irrigation Maintenance Schedule.
<br />(a) Landscapes shall be maintained to ensure water use efficiency. A
<br />regular maintenance schedule shall be submitted with the Certificate of
<br />Completion.
<br />(b) A regular maintenance schedule shall include, but not be limited
<br />to, routine inspection; auditing, adjustment and repair of the irrigation
<br />system and its components; aerating and dethalching turfareas; topdress-
<br />ing with compost, replenishing mulch; fertilizing; priming; weeding in
<br />all landscape areas, and removing obstructions to emission devices. Op-
<br />eration of the irrigation system outside the normal watering window is
<br />allowed for auditing and system maintenance.
<br />(c) Repair of all "irrigation equipment shall be dune with the originally
<br />installed components or their cquivalc:nosor with components with great-
<br />er efficiency.
<br />(d) A project applicant is encouraged to implement established land-
<br />scape industry sttstaiinablc Best Practices for all landscape maintenance
<br />activities.

<br />Water Use Analysis.
<br />(a) All landscape irrigation audits shall be conducted by a local agency
<br />landscape irrigation auditor or a third party certified landscape irrigation
<br />auditor. Landscape audits shall not be conducted by the person who de-
<br />signed the landscape or installed the landscape.
<br />(b) In large projects or projects with multiple landscape installations
<br />(i.e. production home development -c) an auditing rate of I in 7 hots or

<br />(1) the project applicant shall submit an irrigation audit report with the
<br />Certificate of Completion to the local agency that may include, but is not
<br />limited to: inspection, system tune-up, system test with distribution uni-
<br />formity, reporting overspray or run off that causes overland flow, and
<br />preparation of an irrigation schedule, including configuring irrigation
<br />controllers with application rate, soil types, plant factors, slope, exposure
<br />and any other factors necessary for accurate programming;
<br />(2) the local agency shall administer programs that may include, but
