conditions are required on all irrigation systems, as appropriate for
local climatic conditions. Irrigation should be avoided during windy
or freezing weather, or during rain.
(d) The irrigation system must be designed If the water pressure is
below or exceeds the recommended pressure of the specified
irrigation devices, the installation of a pressure regulating device is
12
required to ensure that the dynamic pressure at each emission device
is within the manufacturer's recommended pressure range for
optimal performance.
1. If the static pressure is above or below the required dynamic
pressure of the irrigation system, pressure-regulating devices
such as inline pressure regulators, booster pumps, or other
devices must 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 must be measured at the point of
connection. These pressure and flow measurements must be
conducted at the design stage. If the measurements are not
available at the design stage, the measurements must be
conducted at installation.

are required as close as possible to the point of connection of the water
supply to minimize water loss in case of an emergency (such as a main line
break) or routine repair.
(e) Backflow prevention devices are required to protect the water supply
from contamination by the irrigation system. A project applicant
must refer to the applicable City code (i.e., public health) for
additional backflow prevention requirements.
(1) A master shutoff valve shall be as close as possible to the point of
connection and is required on all projects: with the exception for
landscapes that make use of technologies that allow for the
individual control of sprinklers that are individually pressurized in a
system equipped with low pressure shut down features
(g) High f Flow sensors that detect and-repeft high flow conditions
created by system damage or malfunction are r° mended
required for all non-residential landscapes and residential
landscapes of 5,000 square feet or larger. The flow sensor must be
in combination with a master shut-off valve.
(h) Manual isolation valves(such as a gate valve,ball valve,or butterfly
valve) shall be required downstream of the point of connection of
the water supply to minimize water loss in case of an emergency
(such as a main line break) or routine repair.
(1) The irrigation system must be designed to prevent runoff, low head
drainage, overspray, or other similar conditions where irrigation
water flows onto non-targeted areas, such as adjacent property,non-
irrigated areas, hardscapes, roadways, or structures.
