Policies
Landscaping and site design help to produce character and shape the visual
image for Carlsbad, creating an enduring impression of the communio.
Sustainable landscape practices ensure that threats to health, safety, well-
being water quality, and the natural environment are mimMked.
Landscaping adds value to a community by establishing a character and image that leads to increased
property values. However, many other values of landscaping are not always recognized by the
general public. In addition to aesthetic and recreational values, landscaping can play a key role in the
prevention of soil erosion, water conservation, storm water management, fire protection, energy
efficiency, and long-term health and viability of natural habitat areas. The following policies
embrace these values and provide the framework for the more technical design standards and
requirements in the subsequent sections of this manual.
A. Inter-relationship
Although the policies listed on the following pages are categorized under various headings, they are
often inter-related and may apply to more than one categoiy (although only stated once). Similarly, the
design standards and requirements of the different sections of this manual may also be inter-related.
B. Sustainability Policies
• Landscapes shall incorporate sustainable site design practices wherever practicable.
• Low Impact Development strategies shall be incorporated into the landscape design concept.
• Opportunities for installation of solar energy or utilization of passive solar design features such
as shade trees shall be optimized.
C. Water Conservation Policies
• Water use associated with irrigation of outdoor landscaping shall be reduced to comply with the
State of California Water Conservation in Landscaping Act by establishing a maximum amount
of water to be applied to landscaping and by designing, installing and maintaining water efficient
landscapes not to exceed the maximum water allowance.
• Landscape systems shall be designed and maintained to be compatible with the naturally semi-
arid environment in Carlsbad.
City of Carlsbad Landscape Manual
SECTION 2: POLICIES
The use of state-of-the-art irrigation technology to conserve water is encouragcdrequired. •
• Landscape design shall promote the values and benefits of landscapes while recognizing the
need to utilize water and other resources as-efficiently as possible.
• Owners of existing landscapes are encouraged to use water efficiently and without waste.
• The principles of water efficient landscaping shall be incorporated into the design and
maintenance of landscape.
• Plants known to have relatively- high water needs shall be used sparingly and in situations where they
will require the least amount of water.
• Public areas receiving the highest intensity of use, such as recreation areas and urban gathering
spaces shall receive the highest priority for landscape water consumption.
• Irrigation systems for all projects, except for single-family dwellings or front yard irrigation on
individually metered condos, shall be designed to use non-potable, treated recycled water, unless
approved otherwise by the City.
• Use of rain gardens, rain harvesting, and properly-designed graywater systems arc is alse
encouraged.
• In the event of a declared water shortage or mandatory water conservation measures, the—a
project shall comply with all water allocation programs adopted by state and local government.
D. Planting Policies
In general, landscaping shall:
• Enhance and be compatible with the positive character of existing neighborhoods and Carlsbad
as a whole.
• Maintain and enhance the public's health, safety, and welfare through proper design, selection,
and location of plant materials and other landscape features.
• Incorporate native and drought tolerant plant matrials whenever possible.
• Ensure that invasive or noxious plants are not used.
• Feature ground cover, shrubs, and trees to screen elements of unsightliness and screen/soften
new improvements.
• Provide privacy where appropriate.
• Accentuate and enhance architecture.
• Provide and enhance opportunities for outdoor recreation, relaxing and eatingdinincr.
E. Irrigation Policies
• Irrigation systems shall be designed to provide the optimum amount of water to the landscape
for plant growth without causing soil erosion and runoff.
8 City of Carlsbad Landscape Manual
SECTION 2: POLICIES
• Irrigation plans shall promote the industry standard for public safety in all aspects of the
irrigation system.
F. Streetscape Program Policies
• Landscaping shall accentuate positive, natural, historical, and architectural elements of Carlsbad.
• Landscaping shall be designed toward a goal of providing a pleasing and safe vehicular and
pedestrian experience.
G. Fire Protection Policies
• Landscape treatments shall be designed to mitigate fire dangers to structures adjacent to
hazardous or native vegetation.
• Landscape treatments for the purposes of fire protection shall be performed in a manner which
limits disruption to environmentally sensitive areas while still achieving conformance with the
fire protection standards.
H. Slope Revegetation/Erosion Control Policies
• Erosion potentials shall be mitigated through erosion control planting/slope revegetation.
• Irrigation shall be designed to apply optimum water to the slope plants without causing erosion.
• Plant materials used on slopes shall be those species that are known to have low water
requirements and rooting systems of various depths that will minimize erosion and soil slippage.
• Plant materials used shall be compatible in cultural requirements (exposure, soils, water needs,
etc.) and aesthetic appearance to adjacent natural landscapes.

SECTION 3: PRELIMINARY CONCEPT PLANS
Preliminary Concept Plans
Preliminag Concept Plans provide the City with a clear impression of how a
proposed development will look, function, and be maintained The plans should
depict, in a general way, how the proposed project will conform to the policies
and requirements of the Landscape Manual, Water Efficient Landscape
Ordinance, and other applicable codes and ordinances listed in Section 1.
A. Submittal Requirements
Preliminary Concept Plans must be submitted along with other required plans and documents at the
time of application for discretionary project approval. The type of concept plans required is
dependent upon the size and type of project, location within or outside of the coastal zone, and
adjacency to sensitive habitat area. The following list includes the various types of concept plans
and when each type of plan is requited:
1. CONCEPTUAL LANDSCAPE PLAN
A person applying for a discretionary permit shall submit a landscape concept plan as required by
the discretionary permit application. The Conceptual Landscape Plan demonstrates the landscaping
and features that will be included in the project. If the project is located within a master plan or
specific plan area, any special landscape requirements of those plans shall be incorporated into the
conceptual landscape plan. "Typical" plans may be used for residential lots or planned developments
with developer instilled landscaping. Special areas may require enlargements or detflils as requested by the
City.
2. CONCEPTUAL WATER CONSERVATION PLAN
A Conceptual Water Conservation Plan is required for all projects that require conceptual landscape
plans, except those specifically exempted from the Water Efficient Landscape Ordinance The
Conceptual Water Conservation Plan demonstrates to the City how the proposed development will
use all practicable means available to conserve water in the landscape and provides assurance that
the conceptual plans conform to the City's Water Conservation Policies and Water Efficient
Landscape Ordinance.
3. CONCEPTUAL FIRE PROTECTION PLAN
A Conceptual Fire Protection Plan is required when a proposed project contains or is bounded by
hazardous vegetation and/or within an area bounded by a Very High Fire Hazard Severity Zone as
determined by the Fire Code Official. The plan demonstrates how potential fire hazards will be

SECTION 3: PRELIMINARY CONCEPT PLANS
addressed. Fuel modification zones may be shown either on the landscape concept plan or on a
separate exhibit. Refer to Section 5 - Fire Protection Requirements for additional information.
4. CONCEPTUAL MAINTENANCE RESPONSIBILITY EXHIBIT
A Conceptual Maintenance Responsibility Exhibit is required when landscape maintenance activities
are intended to be performed by more than one entity. The exhibit shall clearly identify the various
areas of landscape maintenance responsibilities (private, common area/HOA, City, etc). If one entity
is to be responsible for the maintenance the entity shall be stated and identified on the Conceptual
Landscape Plan.

Appendices
Seven Principles for
Water-Efficient Landscapes
1. Planning and Design
• Design for aesthetics, practicality and above all, water efficiency.
• Use plants for natural heating and cooling opportunities next to buildings.
• Take advantage of interesting and colorful drought tolerant plants.
• Consider sun orientation, soil type, slopes, location of utility lines and planned usage.
2. Soil Analysis
• Test soils to determine the need for specific soil amendments.
• Incorporate soil amendments prior to installation of irrigation and planting.
• Add compost and aerate soils for better water absorption and to improve water-holding capacity.
3. Appropriate Plant Selection
• Select plants that are native to your region.
• Select plants based on their ultimate size in order to reduce pruning maintenance.
• Group plants together according to their water and sun needs (hydrozones).
• Use plants with minimal water requirements on hot, dry areas with south and west exposures.
• Limit the use of plants that require more moisture, and if used, select planting areas that are in the
cooler areas on north and east facing slopes and walls.
• Reduce evaporation by using trees to shade the soil and block the wind.
4. Practical Turfgrass Areas
• Limit the use of turfgrass to reduce maintenance and watering costs.
• Design turfgrass areas for practical purposes such as play areas.
5. Efficient Irrigation
• Water deeply and infrequently to develop deep root ‘systems.
• Water in the evening or early morning to reduce water loss due to evaporation.
• Adjust your controller monthly to accommodate changing weather conditions.
• Install rain-sensor devices that automatically shut off irrigation during rain events.
• Adjust irrigation systems to eliminate runoff, low head drainage and overspray.
6. Use of Mulches
• Use mulch to keep plant roots cool, minimize erosion and reduce weed growth.
• Add organic mulches to decompose and add nutrients to the soil.
• Limit the use of rocks around plants because it will make the area hotter.
7. Appropriate Maintenance
• Use organic fertilizers and composting to improve soil texture.
• Replace mulch as it decomposes.
• Occasional pruning of trees and shrubs to remove dead stems promotes blooming and controls
height/ spread.
• Aerate turfgrass areas in the spring and fall.
• Regularly inspect, maintain and adjust irrigation systems.

High and Moderate Fuel Plants
HIGH FUEL PLANTS
The following species are highly flammable and should be avoided when planting within the first 50
feet adjacent to a structure. The plants listed below are more susceptible to burning, due to rough or
peeling bark, production of large amounts of litter, vegetation that contains oils, resin, wax, or pitch,
large amounts of dead material in the plant, or plantings with a high dead to live fuel ratio. Many of
these species, if existing on the property and adequately maintained (pruning, thinning, irrigation,
litter removal and weeding), may remain as long as the potential for spreading a fire has been reduced
or eliminated. This list is intended as a guide only and does not incorporate all flammable species.
The applicant/designer is responsible to research all proposed plantings to insure they are low fuel
species.

SHOWN IN STRIKETHROUGH/UNDERLINE FORMAT
AMENDMENTS TO CHAPTER 18.50
WATER EFFICIENT LANDSCAPE
Section 18.50.010
18.50.010 - Purpose.
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 and
are subject to ever increasing demands, and that California's continued economic prosperity is
dependent on adequate supplies of water being available for future uses. 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
legislative amendment AB 1881, 2006 Stats Chapter 559 enacting the Act; and the 2006
development landscape design requirements established by the Act. Consistent with the
legislature's findings, the purpose of this chapter is to:
1. Promote the values and benefits of la ndsc3pcs while recognizing the need to utilize water and
landscaping practices that integrate and go beyond the
conservation and efficient use of water;
2. Establish a structure for planning, designing, installing, maintaining, and managing water
efficient landscapes in new construction and rehabilitated prolects by encouraging the use of a
watershed approach that requires cross-sector collaboration of industry, government and
property owners to achieve the many benefits possible;
3. Promote the use, when available, of treated recycled water, for irrigating 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.
B. Landscapes that are planned, designed, installed, managed and maintained with the watershed
based approach can improve Carlsbad's environmental conditions and provide benefits realizing
sustainability goals. Such landscapes will make the urban environment resilient in the face of
climatic extremes. Consistent with the purpose of this chapter, conditions in the urban setting will
be improved 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 granting 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.
I& Protecting existing habitat and creating new habitat by choosing local native plants, climate
adapted non-natives and avoiding invasive plants. Utilizing integrated pest management with
least toxic methods as the first course of action.
Section 18.50.020
18.50.020 - Authority.
The city planner or designee, shall administer this chapter.
Section 1830.030
18.50.030 - Incorporation of the landscape manual by reference.
The City of Carlsbad Landscape Manual Policies and Requirements f"Landscape Manual' is incorporated
by reference into this chapter. Should any provision of the landscape manual conflict with any provision
of this chapter, the provisions of this chapter shall control.
Section 18.50.040
18.50.040 - Findings.
This chapter implements the Act. The requirements of this chapter reduce water use associated with
irrigation of outdoor landscaping by setting a maximum amount of water to be applied to landscaping.
The landscape manual contains the technical procedures related to the planning, design, installation,
maintenance and management of water efficient landscapes consistent with the water allowance. The
provisions contained in this chapter and/or the landscape manual 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 restrictions on irrigation and process are similar, but have been
modified to account for Carlsbad's existing regulatory procedures.

Sustainable Landscaping r Why Use Mulch?
Homeowner's Guide
Sustainable Site Design
Drainage & Stormwater Management
• Reduce stormwater run-off through the use of
planted swales, rain gardens and other Low Impact
Development (LID) solutions,
• Minimize impervious surfaces.
• Use permeable paving materials to reduce
stormwater run-off and allow rain water to be
absorbed into the ground and replenish
groundwater.
Energy Conservation
• Create an energy-efficient landscape design
through the proper placement and selection of
shade trees and creation of wind breaks.
• Reduce the "heat island" effect by using low heat-
emitting paving materials and maximize shading of
all paved areas.
• Use solar-powered landscape lighting.
• Use mulch made from recycled wood
construction materials.
Fire Prevention
• Incorporate fire buffers in areas adjacent to
native habitat.
• Use low-combustible plant materials in the fire
buffers.
---4101.1.1MMium••••••
Sustainable Products
• Use sustainably harvested wood or composite
wood products for decking and other landscape
projects.
• Use recycled products, such as glass and old
bricks to create paving stones or other
landscape features.
Soil Conditions
• Provide 2 inches of compost tilled into the top
6 to 12 inches of soil.
• Remove and store topsoil before grading.
• protect soil from compaction during construction.
• Aerate compacted soils before planting.
• Incorporate soil amendments as recommended by
a soils testing laboratory.
Wildlife Habitat &
Native Plant Communities
• Enhance wildlife habitat in urban environments by
using non-invasive plant materials.
• Use appropriate buffers between development and
native areas.
• Water loss due to evaporation is reduced
by using mulch.
• Mulch keeps the roots cool
• Weed growth is reduced when mulch is
used
• Mulch helps to minimize erosion, dust and
mud problems.
• As mulch decomposes, nutrients are
added to the soil.
• Landfill waste and costs of disposal are
reduced.
• Mulching mowers decrease the am unt f
fertilizer needed in lawns.
Hyclrozone is a term used to describe a
grouping of plants that have similar cultural
requirethents of sun exposure, soil types
and water needs. Plants that are grouped
into hydrozones and irrigated according to
their common needs require the least
amount of water for optimum growth,
plant health and maintenance.
