b. Automatic irrigation controllers utilizing either evapotranspiration or soil moisture
sensor data utilizing non-volatile memory shall be required for irrigation scheduling in
all irrigation systems.
c. If the water pressure is below or exceeds the recommended pressure of the
specified irrigation devices, the installation of a pressure regulating device is
required to ensure that the dynamic pressure at each emission device is within the
manufacturer's recommended pressure range for optimal performance.

irrigation system, pressure-regulating devices such as inline pressure regulators,
booster pumps, or other devices shall be installed to meet the required dynamic
pressure of the irrigation system.
2. Static water pressure, dynamic or operating pressure and flow reading of the
water supply shall be measured at the point of connection. These pressure and
flow measurements shall be conducted at the design stage. If the measurements
are not available at the design stage, the measurements shall be conducted at
installation.
d. Sensors (rain, freeze, wind, etc.), either integral or auxiliary, that suspend or alter
irrigation operation during unfavorable weather conditions shall be required on all
irrigation systems, as appropriate for local climatic conditions.
e. Manual shut-off valves (such as a gate valve, ball valve, or butterfly valve) shall be
required, as close as possible to the point of connection of the water supply, to
minimize water loss in case of an emergency or routine repair.
f. Backflow prevention devices shall be required to protect the potable water supply
from contamination by the irrigation system.
Ord No. 06-18, Adopted 9/18/2018, Item No. 4.7 Page 13 of 22
