Thelocal agency may designate another
agency, such as a water purveyor to
assume some or all of the responsibilities
of enforcing a water efficient landscape
ordinance
MODEL WATER EFFICIENT LANDSCAPE ORDINANCE (MWELO) PROVISIONS
Any plants may be used selected for
the landscape, providing the Estimated
Applied Water Use recommended for
the project site does not exceed the
Maximum Applied Water Allowance
The following is highly recommended:
(a) Protection and preservation of
native species and natural vegetation.
(b) Selection of water efficient plants.
(c) Selection of trees based on
applicable local tree ordinance or tree
shading guidelines.
(d) Selection of plants from local and
regional landscape program plant lists
Plants shall be selected and planted
appropriately based upon their
adaptability to the climatic, geologic,
and topographical conditions of the
project site.
Weather-based irrigation controllers, soil
moisture based controllers or
other self-adjusting irrigation controllers, shall
be required for all irrigation systems.
Sensors (e.g., rain, freeze, wind, etc.), either
integral or auxiliary, that suspend irrigation
operation during unfavorable weather conditions
shall be required on all irrigation systems, as
appropriate for local climatic conditions
Irrigation scheduling shall incorporate the use of
evapotranspiration data such as those from the
California Irrigation Management Information
System (CIMIS) weather stations or other
validated weather data or soil moisture
monitoring system to apply the appropriate
levels of water for different climates.
Overhead irrigation shall be scheduled between
8:00PM and 10:00AM, unless weather conditions
are unfavorable.
Avoid irrigating during times of high wind or high
temperature.
AUTOMATIC IRRIGATION SYSTEMS &
IRRIGATION SCHEDULES
The irrigation system shall be designed to
prevent runoff, low head drainage,
overspray, or other similar conditions
where irrigation water flows onto
adjacent property, non-irrigated areas,
hardscapes walks, roadways, or
structures.
Installation of turf on slopes greater than
4:1 shall not be permitted
Installation of long, narrow, or irregularly
shaped turf , landscape and median areas
less than eight (8) feet in width in any
direction shall be irrigated with
subsurface irrigation or other low volume
irrigation technology.
Irrigated areas (including turf) within 24
inches of non-permeable hardscape shall
be irrigated with drip irrigation or
subsurface irrigation technology.
The AQUASave® Post Construction GPS Audit is the best, most accurate and
least expensive way to ensure that new and existing irrigation installations
have been installed to plan and are compliant with the provisions of AB 1881.
