POUCIES AND REQUIREMENTS
• INFO
Bl ACTION
RECOMMENDED ACTION:
That the Parks and Recreation Commission: 1) receive the staff presentation and 2) provide feedback to
staff regarding the draft City of Carlsbad Landscape Manual Policies and Requirements.
ITEM EXPLANATION:
On May 11, 2010, the City Council adopted Carlsbad Municipal Code (CMC) Chapter 18.50 - Water
Efficient Landscape Ordinance (WELO) in accordance with the legislative amendment (AB 1881) to the
Water Conservation in Landscaping Act (2006). Chapter 18.50 was based on the model WELO that was
developed for the San Diego County region. The WELO contains many technical and procedural
requirements that are similar to the requirements specified in the Landscape Manual Policies and
Requirements (landscape manual). However, it also mandates new water conservation requirements to
establish a "water budgef and prepare a water efficient landscape worksheet and documentation
package.
The update to the landscape manual is a follow up item that combines the technical equations,
requirements and procedures from Chapter 18.50 with the existing landscape manual's policies
requirements and guidelines. The resulting document is a new re-formatted landscape manual with a built-
in flexibility that will enable the City to be more responsive to adjustments that are necessary due to
changes in the landscape industry/technology or unique situations. Additionally, the development
community will benefit from the proposed revisions, which will:
• Result in a comprehensive updated landscape manual which will be used in conjunction with
Chapter 18.50 to implement AB 1881.
• Resolve discrepancies between the landscape manual and Chapter 18.50.
• Eliminate the requirement for mylars:
- The City will no longer store mylars of landscape plans for private projects.
- Digital copies of the approved plans will be available on the City's Document Management
System.
• Eliminate the requirement for as-built construction and planting plans:
- Irrigation as-built plans are required by CMWD due to the use of recycled water.
- Final approval of landscape installations can occur sooner.
• Provide flexibility for projects that incorporate Low Impact Development (LID) features.
The Parks and Recreation Commission has purview over the Streetscape Program and Arterial
Streetscape Themes sections of the landscape manual. No substantial changes were made to these
sections. However, an addition worth noting is the allowance for modifications to the arterial median
design if the modifications are necessary to incorporate LID features (Section 6.D.2) or a pervious paving
alternative (Appendix D - footnote). These components were added to provide flexibility for future projects
that may need modified median designs in order to comply with the City's Standard Urban Storm Water
Management Plan (SUSMP).
The draft landscape manual was developed by the Planning Division with input and review by the City's
landscape consultant, Parks and Recreation Department, Land Development Engineering Division,
Utilities Department, and landscape architecture, planning, and development firms. The Planning
Commission reviewed the draft landscape manual on January 18, 2012 and their recommendations are
included in Attachment 4.
Comments received by the Planning Commission, the Parks and Recreation Commission, and the public
will be incorporated into the landscape manual and/or fon/varded to the City Council.

SECTION 1: APPLICABILITY
H. Landscape Cheddist
A Landscape Checkiist is provided in Appendix B. The checklist is required for the review of the
landscape construction documents. However, because the checklist includes many design standards
and requirements that are appHcable to both Preliminary Concept Plans and Landscape
Construction Documents, it can also be used by the plan preparer as a reference document during
preparation of the Conceptual Landscape Plans. Note that the checklist does not encompass all of
the landscape manual requirements, nor does it include the entire text of the listed items. The plan
preparer should refer to the main text of the landscape manual to ensure that all of the design
standards and requirements are incorporated into both the conceptual landscape plans and
landscape construction documents.

Poiicies
Landscaping and site design help to produce character and shape the visual
image for Carlsbad, creating an enduring impression of the community.
Sustainable landscape practices ensure that threats to health, safety, well-
being, water quality, and the natural environment are minimi^d.
Landscaping adds value to a community by estabUshing a character and image that leads to increased
property values. However, many other values of landscaping are not always recognized by the
general pubUc. In addition to aesthetic and recreational values, landscaping can play a key role in the
prevention of soU erosion, water conservation, storm water management, fire protection, energy
efficiency, and long-term health and viabUity of natural habitat areas. The foUowing poUcies
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 poUcies Usted on the foUowing pages are categorized under various headings, they are
often inter-related and may apply to more than one category (although only stated once). SimUarly, the
design standards and requirements of the different sections of this manual may also be inter-related.
B. Sustainability Policies
• Landscapes shaU incorporate sustainable site design practices wherever practicable.
• Low Impact Development strategies shaU be incorporated into the landscape design concept.
• Oppormnities for instaUation of solar energy or utiUzation of passive solar design feamres such
as shade trees shaU be optimized.
C. Water Conservation Policies
• Water use associated with irrigation of outdoor landscaping shaU be reduced to comply with the
State of CaUfornia Water Conservation in Landscaping Act by estabUshing a maximum amount
of water to be appUed to landscaping and by designing, instalUng and maintaining water efficient
landscapes consistent with the maximum water aUowance.
• Landscape systems shaU be designed and maintained to be compatible with the naturaUy semi-
arid environment in Carlsbad.
7 City off Carisbad Landscape Manual
ECTION 2: POLICIES
Water Conservation Poiicies (continued)
The use of state-of-the-art irrigation technology to conserve water is encouraged.
Landscape design shaU promote the values and benefits of landscapes whUe recognizing the
need to utiUze water and other resources as efficienfiy as possible.
Owners of existing landscapes are encouraged to use water efficiendy and without waste.
The principles of water efficient landscaping shaU be incorporated into the design and
maintenance of landscape.
Plants known to have relatively high water needs shaU be used sparingly and in situations where they
wiU require the least amount of water.
PubUc areas receiving the highest intensity of use, such as recreation areas and urban gathering
spaces shaU receive the highest priority for landscape water consumption.
Irrigation systems for aU projects, except for single-famUy dwelUngs or front yard irrigation on
individuaUy metered condos, shaU 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 are also
encouraged.
In the event of a declared water shortage or mandatory water conservation measures, the project
shaU comply with aU water aUocation programs adopted by state and local government.
D. Planting Policies
In general, landscaping shaU:
Enhance and be compatible with the positive character of existing neighborhoods and Carlsbad
as a whole.
Maintain and enhance the pubUc's health, safety, and welfare through proper design, selection,
and location of plant materials and other landscape feamres.
Incorporate native and drought tolerant plant materials whenever possible.
Ensure that invasive or noxious plants are not used.
Featare ground cover, shrubs, and trees to screen elements of unsightUness and screen/soften
new improvements.
Provide privacy where appropriate.
Accenmate and enhance architecture.
Provide and enhance opportunities for outdoor recreation, relaxing and eating.
E. Irrigation Policies
• Irrigation systems shaU be designed to provide the optimum amount of water to the landscape
for plant growth without causing soU erosion and runoff

SECTION 3: PRELIMINARY CONCEPT PLAN
Preliminaty Concept Pians
Preliminary Concept Plans provide the City with a clear impression of how a
proposed development will look, function, and he maintained. The plans should
depict, in a general way, how the proposed project mil 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
PreUminary Concept Plans must be submitted along with other required plans and documents at the
time of appUcation 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 foUowing Ust includes the various types of concept plans
and when each t5^e of plan is required:
1. CONCEPTUAL LANDSCAPE PLAN
A person applying for a discretionary permit shaU submit a landscape concept plan as required by
the discretionary permit appUcation. The Concepmal Landscape Plan demonstrates the landscaping
and feamres that wiU 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 shaU be incorporated into the
concepmal landscape plan. "Typical" plans may be used for residential lots or planned developments
with developer installed landscaping. Special areas may require enlargements or details as requested by the
City.
2. CONCEPTUAL WATER CONSERVATION PLAN
A Concepmal Water Conservation Plan is required for aU projects that require concepmal landscape
plans, except those specificaUy exempted from the Water Efficient Landscape Ordinance. The
Concepmal Water Conservation Plan demonstrates to the City how the proposed development wiU
use aU practicable means avaUable to conserve water in the landscape and provides assurance that
the concepmal plans conform to the City's Water Conservation PoUcies and Water Efficient
Landscape Ordinance.
3. CONCEPTUAL FIRE PROTECTION PLAN
A Concepmal 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 wiU be
11 City off Carisbad Landscape Manual
30
SECTION 3: PRELIMINARY CONCEPT PLAN
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 Concepmal Maintenance ResponsibiUty 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 responsibiUties (private, common area/HOA, City, etc). If one entity
is to be responsible for the maintenance the entity shaU be stated and identified on the Concepmal
Landscape Plan.

• AU proposed outdoor elements including, but not limited to, recreational areas, outdoor eating
areas, hardscape, traUs, and water feamres.
4. LANDSCAPE CHECKLIST
A Landscape Checkiist is provided in Appendix B. The checkUst is required for the review of the
landscape constmction documents. However, because the checkUst includes many design standards
and requirements that are appUcable to both Preliminary Concept Plans and Landscape
Constmction Documents, it can also be used by the plan preparer as a reference document during
preparation of the Concepmal Landscape Plans. Note that the checkUst does not encompass aU of
the landscape manual requirements, nor does it include the entire text of the Usted items. The plan
preparer should refer to the main text of the landscape manual to ensure that aU of the design
standards and requirements are incorporated into the concepmal landscape plans.

based on the character or heritage of that specific area of Carlsbad and are described in more detaU
in Appendix D - Arterial Street Themes. Substimtions for the landscape and hardscape elements
described for each theme are permitted, provided that the median island concrete and landscaping
within the median and right-of-way are designed to provide street scene continuity. Alternative
median designs using Low Impact Development feamres are also possible, as described below.
The specific trees creating a streetscape theme are made up of four types of trees: Median, Theme,
Support, and Project Identity/Accent Trees.
Median Island Trees - These trees complement the
street trees and shaU be instaUed as part of the
required street improvements.
Theme Trees — These trees set the overaU character
of the streetscape and are located along the roadside
but outside the right-of-way.

required.
*^ During the remainder of the year, the cover crop and/or erosion control matting may be used.
On slopes greater than 3 feet in height, erosion control matting shaU be required and a cover
crop shaU not be used, unless otherwise approved by the City.
• Standard #2 - GROUND COVER
One hundred (100%) percent of the area shaU be planted with a ground cover known to
have exceUent soU binding characteristics (planted from a minimum size of fiatted material
and spaced to provide fuU coverage within one (1) year).
• Standard #3 - LOW SHRUBS
Low spreading woody shmbs (planted from a minimum of 1 -gaUon containers) shaU cover a
minimum of seventy (70%) percent of the slope face (at mamre size).
• Standard #4 - TREES AND/OR LARGE SHRUBS
- Trees and/or large shmbs (planted from a minimum of 1-gaUon containers) shaU be instaUed
at a minimum rate of one (1) plant per two hundred (200) square feet.
3. PLANTS

fumre property owner(s) by ensuring that the water meter or point-of-connection (POC) is
located within the ownership boundaries of the landscaped area served by the water meter.
This is especiaUy important on subdivisions and other complex projects that involve offsite
work.
Plans shaU specify the size and type of proposed water service and meter. The location shaU
coincide with locations provided by the pubUc improvement plans.
Plans shaU provide pressure loss calculations for each POC to ensure a minimum ten (10%)
percent residual pressure based on the existing hydrauUc grade Une of the existing water
system and the worse-case zone of the irrigation layout.
• Pipe

Seven Principles for
Water-Efficient Landscapes
1. Planning and Design
• Design for aesthetics, practicaUty and above aU, water efficiency.
• Use plants for natural heating and cooUng opportunities next to buUdings.
• Take advantage of interesting and colorful drought tolerant plants.
• Consider sun orientation, soU type, slopes, location of utiUty Unes and planned usage.
2. Soil Analysis
• Test soUs to determine the need for specific soU amendments.
• Incorporate soU amendments prior to instaUation of irrigation and planting.
• Add compost and aerate soUs for better water absorption and to improve water-holdmg 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 thek 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 waUs.
• Reduce evaporation by using trees to shade the soU and block the wind.
4. Practical Turfgrass Areas
• Limit the use of mrfgrass to reduce maintenance and watering costs.
• Design turfgrass areas for practical purposes such as play areas.
5. Efficient Irrigation
• Water deeply and infrequendy to develop deep root systems.
• Water in the evening or early morning to reduce water loss due to evaporation.
• Adjust your controUer monthly to accommodate changing weather conditions.
• InstaU rain-sensor devices that automaticaUy shut off irrigation during raki events.
• Adjust Urigation systems to eUmkiate mnoff, 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 soU.
• Limit the use of rocks around plants because it will make the area hotter.
7. Appropriate Maintenance
• Use organic fertiUzers and composting to improve soU textare.
• Replace mulch as it decomposes.
• Occasional pruning of trees and shmbs to remove dead stems promotes blooming and controls
height/spread.
• Aerate mrfgrass areas in the spring and faU.
• Regularly inspect, maintain and adjust irrigation systems.

The foUowing species are highly flammable and should be avoided when planting within the first 50
feet adjacent to a stmcture. The plants Usted below are more susceptible to buming, due to rough or
peeling bark, production of large amounts of Utter, vegetation that contains oUs, resin, wax, or pitch,
large amounts of dead material in the plant, or plantings with a high dead to Uve fuel ratio. Many of
these species, if existing on the property and adequately maintained (pruning, thinning, irrigation.
Utter removal and weeding), may remain as long as the potential for spreading a fire has been reduced
or eliminated. This Ust is intended as a guide only and does not incorporate aU flammable species.

10 ,. ^- Legislature determined in the Water Conservation in Landscaping Act
(the "Act"), Govemment Code sections 65591 et seq., that the State's water resources are in
J J 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
requirements established by the Act. Consistent with the Legislature's findings, the purpose of
this ordinance is to: r r
14 Promote the values and benefits of landscapes while recognizing the need
to utilize water and other resources as efficiently as possible;
15 ^ Establish a structure for planning, designing, installing, maintaining,
and managing water efficient landscapes in new construction;
16 ^- Promote the use, when available, of treated recycled water, for irriaatina landscaping; ^ ^
17 ^„ ^- w^*®"" 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
lg lowest practical amount; and
5. Encourage water users of existing landscapes to use water efficiently and without
19 waste.

23 manual conflict with any provision of this chapter, the provisions of this chapter shall take
precedence.
24
18.50.040 Findings.
25 A. This chapter implements the Water Consen/ation in Landscaping Act The
requirements of this chapter reduce water use associated with irrigation of outdoor landscaping
26 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
27 management of water efficient landscapes consistent with the water allowance. The provisions
28
J/7 -2-
6
1 contained in this ordinance 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
2 calculation of MAWA and the resulting restrictions on irrigation and process are similar, though
tailored to the city of Carlsbad's existing regulatory procedures.

A. The State Legislature detemiined in the Water Conservation in Landscaping Act
(the Act"), Govemment 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 Carisbad that implement the 2006 development landscape design
requirements established by the Act. Consistent with the Legislature's findings, the purpose of
this ordinance is to:
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 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
j 2i
5. Encourage water users of existing landscapes to use water efficiently and without
waste.
18.50.020 Authoritv.
A. The citv planner or designee, shail administer this chapter.

January 18, 2012 - Recommendations from Planning Commission
Commissioner Siekmann:
• Concerned about the effects that pesticides and herbicides have on water quality. Staff
recommends adding a new bullet point in Section 8.B.1 - General Landscape
Maintenance (page 58) as follows:
• Integtated Pest Management pdndples and practices shall be included in the maintenance
program.
• Recommended minor wording change in Section 1 .A (page 1) and Section 2.C (page 7)
as follows:
.. by designing, instalUng and maintaining water efficient landscapes not to exceed consistent
"(swA-the maximum \rater aUowance."
• Clarify that the required number of trees per parking space and percentage of landscape
per paved partying area does not apply to parking structures. Staff recommends adding
the following to Section 3. C.13 (page 16):
13. PARKING LOTS AND PERIMETERS lOUTDOOR/AT GRADED
• Recommends that when parking lots on adjacent parcels are used jointly, that there
should be some fiexibility in the width of the landscape buffer.
Staff recommends that this type of situation should be reviewed on a case-by-case
basis. Modifications to requirements may be approved by the city planner provided that
the modification is justified and that the findings in Section 1.E (pages 2-3) can be made.
Commissioner Arnold:
• See attached recommendations.
Commissioner Nygaard:
• Recommends adding to the Sustainable Landscaping Brochure (Appendix F) a
recommendation that homeowners shouid request a copy ofthe irrigation plans so that
future repairs and modifications will be easier. Staff will add a new bullet point under
Sustainable Irrigation Design as follows:
• Ask for and retain a copy of the irrigation plans to facilitate future repairs and
modifications.
Commissioner Schumacher:
• Suggested that a list of the Planning Commission recommendations should be included
for reference for the Parks and Recreation Commission and the City Council.

Landscape Manual, page 1, under "Purpose"
The purpose of this landscape manual is to aid applicants, qualified professionals, and residents
in understanding the City's policies, programs and requirements for landscaping, and to provide
guidance for implementation of Carlsbad's Municipal Code Chapter 18.50- Water Efficient
Landscape Ordinance (WELO). The City's WELO implements the State of California Water
Conservation in Landscaping Act to reduce water use associated with irrigation of outdoor
landscaping by setting a maximum amount of water to be applied to landscaping and by
designing, installing and maintaining water-efficient l&ndscapes consistent with the maximum
water allowance.
(new copy to be inserted follows)
California's water system is in a crisis. For the first time in the state's history, the water supply
and delivery system may not be able to meet our growing needs. At the same time, critical
environmental resources are in peril. From aging infrastructure to population growth to climate
change, we face a complex set of problems that threaten the future of California's population,
economy and environment. Southern California, In particular, has suffered through a long
period of drought. Most ofthe water we use comes from fresh water imports from Colorado,
Oregon and Mexico. We are approaching a water crisis, and studies have shown that more than
40% ofthe total fresh water used In an average California home goes to irrigating our
landscape.
Resolution-additional "whereas" entries after WHEREAS, CMC Chapter 18.50 incorporates by
reference the Landscape Manual Policies and Requirements:
