RECOMMENDED ACTION:
That the City Council INTRODUCE Ordinance No. CS-089 . APPROVING Zone Code Amendment
ZCA 10-01 and Municipal Code Amendment 10-01 repealing Chapter 21.220 (Water-Efficient
Landscaping) of the Carlsbad Municipal Code and adding and enacting Chapter 18.50 (Water
Efficient Landscape) to the Carlsbad Municipal Code.
ITEM EXPLANATION:
The Water Conservation in Landscaping Act of 2006 (AB 1881) requires local agencies to adopt the
State's Model Water Efficient Landscape Ordinance (MWELO) or an equivalent by January 1, 2010.
Since the City has not yet adopted an ordinance, the State's MWELO is currently in effect. A regional
model ordinance was developed (November 2009) by the County Water Authority, in conjunction with
various stakeholders (including the City of Carlsbad), to be equivalent to or at least as effective as the
State ordinance, and which is intended to promote consistency in landscape regulations among land
use authorities throughout San Diego County. The proposed ordinance, which is modeled after the
regional ordinance, would add a new Chapter 18.50 (Water Efficient Landscape Regulations) to the
Municipal Code and would repeal Chapter 21.220 (Water-Efficient Landscaping) of the Zoning
Ordinance which does not meet the requirements of AB 1881. The removal of the prior standards
from the Zoning Ordinance does not need to be reviewed by the Planning Commission under
Government Code Section 65853 because the standards do not impose a regulation on the uses
allowed on the property.
The ordinance has been designed to implement the Water Conservation in Landscaping Act and has
been reviewed to ensure that the provisions are equivalent to and at least as effective in conserving
water as the provisions of the State MWELO. For example, the ordinance includes provisions for (1)
water conservation by the appropriate use and grouping of plants that are well adapted to particular
sites and conditions; (2) a landscape water budget that establishes a maximum amount of water to be
applied through the irrigation system; (3) automatic irrigation systems and schedules based on
climatic conditions, terrains, soil types, and other environmental conditions; (4) onsite soil assessment
and soil management plans that include grading and drainage to promote healthy plant growth and
prevent excessive erosion and runoff; and (5) the use of recycled water when it is available which
further reduces the dependence on potable water supplies.
The proposed regulations reflect improvements for landscape and irrigation design plans, irrigation
technologies, and water management for achievable water savings to reduce water demand and
waste. The new ordinance applies to new or rehabilitated landscapes of 2,500 sf or greater for
commercial, industrial, institutional, multi-family, developer-installed residential or common landscape,
and public agency projects, where a building permit or discretionary action is required. With regard to
homeowner-installed landscapes, the regulations would only apply if the landscaped area is 5,000 sf

or greater. Although projects under these thresholds are exempt, applicants will be encouraged to
implement water efficient landscaping by completing a "best landscape design practices checklist."
The process for landscape plan approval will remain essentially the same as current practice, with the
exception of a new requirement for a Water Efficient Landscape Worksheet. The worksheet is used
to calculate the maximum amount of water that can be applied for a given landscape project. The
landscape design must take into account plant type and water needs, evapotranspiration rate, and
irrigation efficiency so as not to exceed the calculated water "budget". Currently, the fees for
landscape plan check and inspections are calculated based on the square footage of landscaped area
and adoption of the proposed ordinance will not result in an increase of fees.
The proposed ordinance incorporates the City's Landscape Manual by reference. The manual, which
was approved by the City Council in 1990, contains additional city landscaping policies; detailed
design standards; and plan submittal, approval, and inspection requirements. The Landscape Manual
is in the process of being updated to be consistent with and provide guidance to applicants on how to
comply with the new state law. When completed, the updated manual will be presented to the City
Council for adoption.
FISCAL IMPACT:
No fiscal impacts are expected to occur as a result of adopting the new water efficient landscape
ordinance, with the exception of staff and landscape consultant time that will be required to update the
City of Carlsbad Landscape Manual in accordance with AB 1881. The cost of consultant services will
be less than $20,000, and is within the Planning Division's authorized budget.
ENVIRONMENTAL IMPACT:
The proposed amendments are exempt from environmental review pursuant to CEQA Section 15307,
which exempts activities or regulatory actions that enhance or protect a natural resource. A notice of
exemption will be filed with the County Clerk upon approval of the project.

18.50.010 Purpose.
8 A. The State Legislature determined in the Water Conservation in Landscaping Act
(the "Act"), Government Code sections 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. The general purpose of this chapter is to establish water use standards for
landscaping in the City of Carlsbad that implement the 2006 development landscape design
11 requirements established by the Act. Consistent with the Legislature's findings, the purpose of
this ordinance is to:
12 1. Promote the values and benefits of landscapes while recognizing the need
to utilize water and other resources as efficiently as possible;
2. Establish a structure for planning, designing, installing, maintaining,
and managing water efficient landscapes in new construction;
3. Promote the use, when available, of treated recycled water, for irrigating
15 landscaping;
4. 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; and
. _ 5. Encourage water users of existing landscapes to use water efficiently and without
waste.
18 18.50.020 Findings.
19 A. This chapter implements the Water Conservation in Landscaping Act. The
requirements of this chapter reduce water use associated with irrigation of outdoor landscaping
20 by setting a maximum amount of water to be applied to landscaping and by designing, installing
and maintaining water efficient landscapes consistent with the water allowance. The provisions
21 of this ordinance are equivalent to and at least as effective as the provisions of the state Model
Water Efficient Landscape Ordinance because the calculation of MAWA and the resulting
22 restrictions on irrigation and process are similar, though tailored to the City of Carlsbad's
existing regulatory procedures.

an irrigation system with a precipitation rate of 0.75 inches per hour or less to prevent runoff and
5 erosion. As used in this chapter, 25 percent grade means one foot of vertical elevation change
for every four feet of horizontal length. An applicant may employ an alternative design if the
6 plan demonstrates that no runoff or erosion will occur.

trenching. In cases where on-grade pipe is allowed it shall be the galvanized type or UVR
10 resistant PVC approved by the Planning Director.
8. The plan shall provide that only low volume or subsurface irrigation shall be used
11 to irrigate any vegetation within 24 inches of an impermeable surface unless the adjacent
impermeable surfaces are designed and constructed to cause water to drain entirely into a
12 landscaped area.
9. The irrigation system shall provide for the installation of a manual shutoff valve
as close as possible to the water supply. Additional manual shutoff valves shall be installed
between each zone of the irrigation system and the water supply.

regulated by an automatic irrigation controller.
11. The irrigation system shall be designed with a landscape irrigation efficiency
necessary to meet the MAWA.
12. The plan shall describe each automatic irrigation controller the system uses to
regulate the irrigation schedule and whether it is a weather based system or soil moisture
'' detection system. The plan shall depict the location of electrical service for the automatic
irrigation controller or describe the use of batteries or solar power that will power valves or a
smart controller.

Hi Steve-
Thank you for your comments.
On page 11, the formula is written correctly. We had an internal discussion on that specific question, and concluded
that that because the Mathematical Orders of Operation require that items in parenthesis must be completed first, in
the following order: multiplication, division, addition, and subtraction; that the additional parenthesis are not
necessary in the equation.
On page 12, the landscape and irrigation schedule is not required until prior to final approval of the landscape
installation (see Section 18.50.230A.2.b.). At that time, the maintenance contractor should be selected. And you are
right, the contractor may change over the life of the project. However, the purpose of the information is to ensure that
upon completion of the landscape installation, that there is an entity who is responsible for the landscape
maintenance.
I hope this helps to address your concerns. Please let me know if you have any additional questions.
Sincerely-
bk

Subject: Water efficient landscape Ordinance
Barbara,
I do not think I am going to be able to make it this evening to speak on the item. However, I did want to let you know that
Ordinace was reviewed and it all seems good.
We do have two comments:
Page 11, Section 18.50.140: The formula is a little confusing. I believe it needs two more parentheses as follows:
ETWU = (ETo)(0.62)({PFxHA/IEl
Page 12, Section 18.50.220, A.9: Identification of entity responsible for maintenance. This will likely not be known
at the point of permit application. Should clarify that HOA or property owner can be listed as the responsible party
if no landscape maintenance company has been selected yet. In practice, property owners, HOA's, change
landscape maintenance companies all the time. There is very little purpose in having this information provided to
the city if it is either not yet known or will likely change multiple times over the life of the project and the
landscaping.
Again thank your for sending me the copy of the Ordinance and I hope these comments are helpful.
