HO CITY A CITY MG RECOMMENDED ACTION: Adopt Resolution No/^'^Y adopting the revised Landscape Manual Policies and Requirements and Ordinance NoQS-iS1! deleting the word "guidelines" from Title 11, Chapter 11.06, Section 11.06.025 of the Municipal Code. ITEM DISCUSSION: In 1983, the City Council adopted the Landscape Guidelines Manual. This manual outlines standards and guidelines to be followed by developers and landscape designers in preparing plans for approval by the City. In response to the need to incorporate new ideas and address recent issues related to landscaping, staff has revised the Landscape Manual (Exhibit 2). During the revision process, staff contacted various governmental agencies, professional organizations, and academic institutions throughout San Diego County as well as the State for input into the document. A draft manual was prepared and circulated to City departments and to several organizations for comments. Major revisions to the manual include: 1. Strengthening the document - eliminating the term "Guidelines" from the title and creating more specific requirements (vs. suggestions). 2. Adding a "Water Conservation Section" - requiring water saving irrigation techniques and limiting high water use plants (including lawns). 3. Revised the "Streetscape Themes" - coordinating landscape "themes" along major arterial roads with other City documents and existing conditions and calling out specific shrub types to be planted in the medians. 4. Updating Technical Standards - using current landscape industry technology. On September 17, the Parks and Recreation Commission recommended approval of the Landscape Manual with the following suggestions: Suggestion #1: Eliminate the term "Open Space" from the "Environmental Resource/Open Space Section." Action Taken: After consulting with the Planning Department, the entire section has been eliminated due to pending future open space issues to be studied (see pages 9 and 29 of the Manual). Suggestion #2: Clarify that both public and private recreation areas are exempt from the turf limitation. Action Taken: Wording has been clarified (see pages 27, C.3-4.2). Suggestion #3: Research City policy on "shake roofs" adjacent to high fire hazard areas and possibly include within the "Fire Protection Section" of the Landscape Manual. Action Taken: The Fire Department has clarified that fire-proof roof materials are already required through the building code for all structures within the City. On October 3, the Water Commission recommended approval of the Landscape Manual with the following suggestions: Suggestion: Revise the wording "Projects MAY be required, at the discretion of the City, to be designed to utilize reclaimed water" to read "Projects SHALL be required ... to utilize reclaimed water. Action Taken: Wording has been so revised (see page 27, C.3-5.1). FISCAL IMPACT: The Planning Department currently contracts consulting landscape plan check services. Development applicants pay a plan check fee that pays for this service. It is not anticipated that the revisions to the Landscape Manual will require any more plan check time than currently exists. After City Council approval of the contents of the Landscape Manual, staff will utilize the services of a graphic artist to enhance the layout of manual, add additional graphics, and prepare the document for printing. Cost for the graphic artist services is estimated at $6,700. Funds are available in the Advanced Park Planning Account No. 001-330-1824-3198. EXHIBITS: 1. Resolution No. 2. Ordinance No. 3.

INTENT Landscaping and site design help produce character and visual image for Carlsbad, creating an enduring impression of the community. The Manual will aid applicants and their landscape architects in understanding the City's policies toward landscaping. It is a comprehensive document listing programs, policies, and requirements relating to landscaping within the City. B. APPLICATION This document applies to all public and private developments requiring discretionary permits or submittal of landscape plans for development permits including but not limited to the following projects: a. private developments b. public parks and recreational facilites c. maintenance districts C. MANUAL FORMAT The Manual is broken down into 4 distinct areas: • Submittals (Section II and III) • Policies and Requirements (Section IV) • Installation, Bonding and Maintenance Requirements (Section V) • Appendix The SUBMITTALS sections tell the applicant: 1. What types of submittals are required. 2. What the intent of requiring the submittal is. 3. Who shall prepare the submittal. 4. What the graphic format shall be. 5. What the contents shall be. The POLICIES AND REQUIREMENTS sections tell the applicant. 1. What the policies are of the City of Carlsbad related to different areas of landscape design. 2. What other related sections of the Manual apply. 3. What are the specific requirements that relate to the different areas of landscape design. INTER-RELATIONSHIP The policies and requirements of the different section may be inter-related, that is they may apply to more than one section although only stated once. For example, one of the policy statements found in the Water Conservation Policies and Requirements section states "Carlsbad is in a naturally semi-arid region. The landscape ethic should be towards designing and maintaining landscape systems compatible with the natural environment." This policy also applies to all other sections as well. As a second example, the requirement that "pressure regulating device shall be used where the static pressure at the point of connection exceeds 80 pounds per square inch" is found in the General Irrigation Policies and Requirements. However, this requirement also pertains to the Erosion Control/Slope Revegetation and the Streetscape Program sections where applicable. Therefore, the users of this manual must pay close attention to the "Other Applicable Sections" paragraph at the beginning of each section as well as cross references throughout the text. D. CONFLICTS WITH OTHER DOCUMENTS If conflicts arise between this manual and other governing documents, the most stringent and/or recent shall apply. E. MINIMUM REQUIREMENTS The policies and requirements within this manual are minimum standards. Projects are encouraged to exceed these standards whenever appropriate. F. VARIANCES Variances may be granted from the policies and requirements of this manual by the City from time to time if undue hardships or special circumstances make the variance request necessary. Variance procedures shall conform to City policy related to the specific modifications being requested at the time of the request. II.PRELIMINARY SUBMTTTALS A. Landscape Concept Plan 1.

G.I-3 The City is establishing these policies and requirements to ensure that sidewalks and other pedestrian walkways are safe for pedestrian use and that crackling or buckling of sidewalks and other pedestrian walkways will be eliminated or minimized. The City is not a guarantor of perfectly flat sidewalks and can only maintain them within its reasonable budgetary powers. However, these guidelines are being established to prevent, to the maximum extent possible, tree roots from invading, disrupting or destroying City sidewalks. Although it remains the property owner's duty to notify the City if a problem arises and liability to third persons may need to be judicially determined, it is hoped that with the City's routine inspection and maintenance program and these policies and requirements, such incidents will be minimized.

Definitions ' "^ PLANTING ZONES Zone One - Lush Landscape 1. Criteria a. Zone One should be utilized only in areas of a development which require a lush green landscape such as areas of high use or visual importance. b. The plantings require an intensive maintenance operation to produce the desired appearance. c. This Zone's anticipated appearance relies on large amounts of irrigation. Annual amounts for a healthy, mature landscape are estimated at over thirty (30") inches of supplemental water annually. 2. Description Zone One may be thought of as a traditional landscape, green, lush, and flowering. Most plants used to produce this effect do not come from a semi- arid type climate found in Southern California. These exotic plants require large amounts of water and intensive maintenance. Although Carlsbad has a mild temperate climate, it remains a semi-arid region, characterized by poor, infertile soil. Natural lush landscapes are found within our area, but only in very limited micro-climates whose special environment can produce the requirements to support this types of landscape. This natural pattern of limited lush landscapes should act as a guide for Zone One's use. These lush landscapes should be utilized for areas of intensive use or as a sensory rich setting in areas visible and important to the majority of users, such as entries, courtyards, pedestrian ways, and recreation areas. APPENDIX A 3. Zone One Plants - Typical species related to this zone might be: - Azalea species - Clivia miniata - Fatsia japonica - Ferns - Asplenium; Blechnum - Fuchsia - Gardenia species - Schefflera actinophylla - Annual flower color - Lawns B. Zone Two - Refined Landscape 1. Criteria a. Zone Two should have an unmanicured appearance, not unkept, but rather a landscape designed to require less intensive types of maintenance such as mowing, pruning, fertilizing, and watering. Plant material whose appearance is not dependent on heavy watering and maintenance care. b. It stresses continually low maintenance by designed plant combinations with matched growth requirements. This zone's water requirements for a mature landscape is estimated between ten (10") and thirty (30") inches of supplemental irrigation water annually. 2. Description Zone Two attempts to reflect the natural constraints of Carlsbad's physical environment. It substitutes for a historically disproportionate use of Zone One's "traditional landscape". Its design and selection of materials promote less maintenance and lower water requirements. 3. Zone Two Plants - Typical species related to this zone might be: - Pittosporum tobira "Wheeleri" - Raphiolepis indica -Hebe - Agapanthus - Psidium guajava - Frageria chiloensis C. Zone Three - Naturalizing Landscape 1. Criteria a. This zone will be planted in low use areas whose visual character will not have a refined appearance. It will have a naturalized appearance similar to areas of native vegetation and may in fact contain native species. b. It will have the ability to "naturalize" once it has been established. Its estimated supplemental water requirement is below ten (10") inches annually. 2. Description Zone Three will be primarily used to create a more natural looking area, such as slopes, periphery areas, and areas of projects where disturbed grounds may need to blend into vegetation. The success of this landscape is directly related to its ability to become self-sufficient within a prescribed period of time. A self-sufficient landscape, Zone Three is capable of sustaining itself as an effective landscape on very limited water and remain healthy. Few newly planted juvenile plants are "drought tolerant", but they develop the ability to adapt to cycles of dry periods once their root systems have developed and have matured and adapted to the site conditions. 3. Zone Three Plants - Typical species related to this zone might be: - Acacia redolens - Mimulus species - Ribes speciosum - Ceanothus - Cassia - Lantana camara - Mahonia - Baccharis pilularis - Rosmarinus officinalis D. Zone Four - Native Landscape 1. Criteria a. Zone Four is an area of existing vegetation whose native character shall remain with very little modification. b. It is planned for low-level active use, which is compatible with the area's natural character. c. In this zone, no water is required. The use of irrigation can adversely affect many plants found in this zone. Introduced plants should be watered individually. 2. Description Zone four consists of natural vegetation, native or naturalized, in which there is no or very little disturbance from site improvements. An area may be planned as a Zone Four landscape to preserve its physical features, its qualities as a natural ecosystem, wildlife habitat, or as open space. These qualities may be used to provide passive recreational opportunities, possibly linked by hiking trails. Zone Four will require a minimal level of upkeep. Its maintenance program will consist of periodic control of debris and minor clearing and/or pruning for fire protection. Retained in their natural non-irrigated condition, these areas will remain relatively dry. Due to this characteristic, a "Fire Protection Program" may be required. THE SEVEN PRINCIPLES OF "XERISCAPE" 1. Good design. 2. Thorough soil preparation. 3. Careful planned use of shrub and lawn areas. 4. Adapted, low water demand plants. 5. Effective and efficient watering methods. 6. Mulched flower and shrub beds. 7. Proper landscape maintenance and management.
