Notes:
(1) Net Irrigable Area determined by subtracting total impervious area (buildings, parking lots, streets, driveways, patios, tennis
courts, etc.) from the total site acreage.
(2) Street Address of Meter or Service: Use permitted established street address of site. However, if multiple meters are
needed or the meter address is not evident, the Permit Clerk in the Development Services Division will obtain an address
during the Process of obtaining a plumbing permit. (See Item 3 in cover letter.)
(3) The table below illustrates the information needed to determine total flow in terms of rate and average daily flow and
determine meter size.

Determine Peak Gallons per Minute (GPM): Zones A + B operating together = 60 + 15 = 75 GPM; Zone C operating separately = 108
GPM. Therefor meter is sized for Zone C at a peak rate of 108 GPM: Meter requirement: 2-inch meter.
Complete table listing each zone, the number of sprinkler heads per zone, the flow rate (GPM) of each sprinkler head, total
GPM for each zone, etc. Determine maximum rate (GPM) by identifying which zones are operating together.
