(a)
The smart controller must be programmed to irrigate between
the hours of 12:00 midnight and 10:00 a.m.
(b)
Proper sprinkler head data and accurate soil/plant/irrigation
information must be entered.

The smart controller programming data shall be posted at the
controller.
(d)

after the initial programming to adjust and fine tune the irrigation
schedule.
D. Irrigation systems programmed and monitored by an irrigation manager:
(1) The property owner must designate a qualified person who will be
the irrigation manager, register that person with the City with defining
qualifications, and display a yard placard signifying that the property

precipitation rate, and irrigation efficiency.
(4) Weekly adjustments shall be made to the irrigation schedule based
on current evapotranspiration (ET) rates or weather conditions.
(5) If it is found that an irrigation manager does not follow any of
the terms prescribed in this article, such person may be disqualified
from acting as an irrigation manager.
E. All automatic irrigation systems:
(1) Shall be equipped with an operational automatic rain sensor device,
which disables the system when a predetermined amount of rainfall
has occurred. Each rain sensor device shall be capable of and programmed
to interrupt the automatic irrigation cycle when 1/4 inch of rain

Considering the soil type so the sprinkler irrigation precipitation
rate is compatible with the soil infiltration rate or dividing the
zone runtimes into multiple short cycles.
(e)
Providing separate control of sloped areas.
(f)
Preventing sprinkler heads from overthrowing onto driveways,
roads, and sidewalks.
(g)
Providing for separate irrigation for parkway strips between
curbs and sidewalks that minimizes overthrow onto walks, pavement,
and other impervious surfaces.
(h)
Using pressure-regulating technology as necessary to ensure
sprinkler heads operate within the manufacturer's recommended range.
The pressure regulation may be:
[1]
Pressure regulation at the point of connection.

[3]
Pressure regulation at the sprinkler head.
[4]
A combination of the above.
