dETWU (Annual Gallons Required) = ETo x 0.62 x ETAF x Area
where 0.62 is a conversion factor that acre-inches per acre per year to gallons per square foot per year.
eMAWA (Annual Gallons Allowed) = (ETo) ( 0.62) [ (ETAF x LA) + ((1-ETAF) x SLA)]
where 0.62 is a conversion factor that acre-inches per acre per year to gallons per square foot per year, LA is the total landscape area in square feet, SLA is the total special landscape area in square feet, and ETAF is .55 for residential areas and 0.45 for nonresidential areas.

Average ETAF for Regular Landscape Areas must be 0.55 or below for residential areas, and 0.45 or below for nonresidential areas.

(D) Appendix D:
Water Efficient Landscape Worksheet
Prescriptive Compliance Option
(a) This appendix contains prescriptive requirements which may be used as a compliance option to the Model Water Efficient Landscape Regulations.
(b) Compliance with the following items is mandatory and must be documented on a landscape plan in order to use the prescriptive compliance option:
(1) Submit a Landscape Documentation Package which includes the following elements:
(B) project applicant
(C) project address (if available, parcel and/or lot number(s))
(D) total landscape area (square feet), including a breakdown of turf and plant material
(E) project type (e.g., new, rehabilitated, public, private, cemetery, homeowner-installed)
(F) water supply type (e.g., potable, recycled, well) and identify the local retail water purveyor if the applicant is not served by a private well
(G) contact information for the project applicant and property owner
(H) applicant signature and date with statement, "I agree to comply with the requirements of the prescriptive compliance option to the MWELO".
(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);
(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% 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% of the plant area excluding edibles and areas using recycled water;
(B) A minimum three inch (3") 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.
(4) Turf shall comply with all of the following:
(A) Turf shall not exceed 25% 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.
(B) Irrigation controllers shall be of a type which does not lose programming date 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 manufacturer's 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.
(c) 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.
