WATER USE EFFICIENCY STATEMENT Provide a narrative summary of the water use efficiency practices applied to the landscape project and answer all of the following questions (attach additional sheets if necessary): Narrative Questions: Did you review the ordinance to learn about the criteria and specifications for landscape design plans? Did you coordinate with the City or local retail water purveyor on the landscape plan? Which criteria and specifications did you apply to the landscape design plan? Did you review the ordinance to learn about the criteria and specifications for the irrigation design plan? Did you coordinate with the City or local retail water purveyor on the irrigation design Which criteria and specifications plan did you apply to your irrigation design plan? ---PAGE BREAK--- Page 5 of 11 of the Water Efficient Work Sheet Did you ask for assistance from the City/local retail water purveyor to calculate a project water budget? Did you receive any water efficient landscape publications from the City or local retail water purveyor? How would you assure the overall quality of the irrigation system? (10) How will you manage the irrigation system for optimum operation and performance? (11) How will you manage the irrigation system to respond to the changing requirement for water in the landscape? (12) Did you apply any stormwater best management practices to the design? 13) If recycled water was available, did you design and install a duel distribution system? (14) Did you select plants from plant lists provided by the City of Palmdale? ---PAGE BREAK--- Page 6 of 11 of Water Efficient Worksheet SECTION C. Water Budget Calculation Section CI. Maximum Applied Water Allowance The Project’s Maximum Applied Water Allowance shall be calculated using this equation: MAWA = (ETo) (0.8) (LA) (0.62) MAWA = Maximum Applied Water Allowance (gallons per year) ETo = Reference Evapotranspiration (inches per year) 0.8 = ET Adjustment Factor LA = Landscaped Area (square feet) 0.062 = Conversion factor (to gallons) Maximum Applied Water Allowance gallons Show calculations: Recycled or Blended Water information If the irrigation water (recycled water or blended water) has electrical conductivity equal to, or greater than, 3 deci Siemens per meter (dS/m) or 3 millimhos per centimeter (mmh/cm) or 2000 mg per liter total dissolved solids (TDS), a leaching factor of up to 10% may be included in the MAWA calculation. The leaching factor shall not exceed 10% of MAWA. Section C2. Estimated amount of water expected from effective precipitation has been eliminated because the City of Palmdale does not receive enough reliable rainfall in any given year to utilize this information. ---PAGE BREAK--- Page 7 of 11 of the Water Efficient Work Sheet Section C3. Estimated Water Use for hydrozones and Estimated Total Water Use The project’s Estimated Total Water Use is calculated using the following formula: EWU = (ETo) (PF) (HA) (0.62) (IE) EWU = Estimated total water use for a hydrozone (gallons) ETo = Reference evapotranspiration (inches per month) PF = Plant Factor HA = Hydrozone area (square feet) 0.62 = Conversion factor IE = Irrigation efficiency Show calculations for each hydrozone (attach additional sheets if necessary). ETWU = ∑I=1 to n (EWUi) i = hydrozone number n = total number of hydrozones Estimated Total Water Show calculations: Section C4. Estimated Applied Water Use - This section has been eliminated because the City of Palmdale does not utilize effective rainfall in these calculations ---PAGE BREAK--- Page 8 of 11 of Water Efficient Work Sheets Section C5: Additional Water Requirements Recreational areas and areas permanently and solely dedicated to edible plants may require water in addition to the Maximum Applied Water Allowance. Please be sure to provide a statement in the landscape design plan and in the irrigation schedule, designating those portions of the landscape to be used for such purposes, and specifying any additional water needed above the Maximum Applied Water Allowance. The total amount of irrigation water allowed for these areas shall not exceed 1.0 of ETo. Show calculations: SECTION D. HYDROZONE INFORMATION Section D1. Hydrozone Map Attach a hydrozone map to the Water Efficient Landscape Worksheet. Hydrozones shall be designated by number, letter, or other designation. Designate the areas irrigated by each valve, and assign a number to each valve. Use this valve number in Section D2 – Hydrozone Table. This map can also assist with pre and final inspections of the irrigation system, and programming the controller. ---PAGE BREAK--- Page 9 of 11 of Water Efficient Work sheet / Section D2. Hydrozone Table (Blank Form) Please complete the hydrozone table(s) for each irrigation point of connection. Use as many worksheets as necessary to provide square footage of landscape area per valve. Irrigation Point of Connection # Controller # Valve Circuit # Plant Type Irrigation Method Area (Sq. Ft.) % landscape area * Plant Type **Irrigation Method CST = Cool Season Turf WST = Warm Season Turf S = Spray HW = High Water Use Plants R = Rotor MW = Moderate Water Use Plants B = Bubbler LW = Low Water Use Plants D = Drip ---PAGE BREAK--- Page 10 of 11 Water Efficient Worksheet Section D3.
