This chapter shall be known as the "City of Encinitas Water
Efficient Landscape Regulations" and may be so cited.
(Ord. 2010-05; Ord. 2016-01)
The State Legislature determined in the Water Conservation in
Landscaping Act (the "Act"), Government Code Section 65591 et seq.,
that the state's water resources are in limited supply. The Legislature
also recognized that while landscaping is essential to the quality
of life in California, landscape design, installation, maintenance
and management must be water efficient. Consistent with the Legislature's
findings, the purpose of this chapter is to:
A.
Promote
the values and benefits of landscaping practices that integrate and
go beyond the conservation and efficient use of water in a manner
at least as effective as the Act and implementing regulations.
B.
Establish
a structure for planning, designing, installing, maintaining and managing
water efficient landscapes in new construction and projects and modified
landscapes.
C.
Promote
the use, when available, of tertiary treated recycled water for irrigating
landscaping.
D.
Use
water efficiently without waste by setting a maximum applied water
allowance (MAWA) as an upper limit for water use and reduce water
use for landscaping to the lowest practical amount.
E.
Encourage
water users of existing landscapes to use water efficiently and without
waste.
F.
Encourage
landscapes that are planned, designed, installed, managed and maintained
to improve environmental conditions, provide benefits and realize
sustainability goals by:
1.
Creating
the conditions to support life in the soil by reducing compaction,
incorporating organic matter that increases water retention, and promoting
productive plant growth that leads to more carbon storage, oxygen
production, shade, habitat and aesthetic benefits.
2.
Minimizing
energy use by reducing irrigation water requirements, reducing reliance
on petroleum-based fertilizers and pesticides and planting climate-appropriate
shade trees in urban areas.
3.
Conserving
water by capturing and reusing rainwater and graywater wherever possible
and selecting climate-appropriate plants that need minimal supplemental
water after establishment.
4.
Protecting
air and water quality by reducing power equipment use and landfill
disposal trips, selecting recycled and locally-sourced materials and
using compost, mulch and efficient irrigation equipment to prevent
erosion.
5.
Protecting
existing habitat and creating new habitat by choosing local native
plants and climate-adapted, non-native plants, avoiding invasive plants
and utilizing integrated pest management with least toxic methods
as the first course of action.

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. Irrigation should be avoided during
windy or freezing weather or during rain.
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
(such as a main line break) or routine repair. Additional manual shutoff
valves shall be installed between each zone of the irrigation system
and the water supply.
f.
Backflow prevention devices shall be required to protect the water
supply from contamination by the irrigation system. A project applicant
shall refer to the applicable local agency code (i.e., public health)
for additional backflow prevention requirements.

type and infiltration rate, shall be utilized when designing irrigation
systems.
k.
The design of the irrigation system shall conform to the hydrozones

on an existing landscape project where the landscaped area exceeds
one acre and the City has reasonable grounds to believe that due to
irrigation runoff, low head drainage, overspray or other similar condition,
water is flowing onto adjacent property, non-irrigated areas, structures,
walkways, roadways or other paved areas of the project.
