(b) Sprinkler heads and other emission devices shall be selected based on what is appropriate for the plant type within that hydrozone. (c) Where feasible, trees shall be placed on separate valves from shrubs, groundcovers, and turf. (d) Individual hydrozones that mix plants of moderate and low water use or moderate and high water use maybe allowed i£ i. the plant factor calculation is based on the proportions of the respective plant water uses and their respective plant factors; or ii. the plant factor of the higher water using plant is used for the calculations. (e) Individual hydrozones that mix high and low water use plants shall not be permitted. (1~ On the landscape design plan and irrigation design plan, hydrozone areas shall be designated by number, letter, or other designation. On the irrigation design plan, designate the areas irrigated by each valve and assign a number to each valve. (g) The irrigation design plan, at a minimum, shall contain: i. the location and size of separate water meters for landscape; ii. the location, type, and size of all components of the irrigation system, including controllers, main and lateral lines, valves, sprinkler heads, moisture sensing devices, rain switches, quick couplers, pressure regulators, and backflow prevention devices; iii. static water pressure at the point of connection to the public water supply; iv. flow rate (gallons per minute), application rate (inches per hour), and design operating pressure (pressure per square inch) for each station; v. irrigation schedule parameters necessary to program smart timers specified in the landscape design; vi. the following statement: "I have complied with the criteria of the Water Efficient Landscape Ordinance and applied them accordingly for the efficient use of water in the irrigation design plan;" and 13 75A-42
