CED WATER EFFICIENT LANDSCAPE MANUAL MCA 11-01/SS 11-03 DEPT. DIRECTOR CITY ATTORNEY CITY MANAGER 14 RECOMMENDED ACTION: That the City Council hold a public hearing and INTRODUCE Ordinance No. cs-175 APj^ROVING Municipal Code Amendment MCA 11-01 and ADOPT Resolution No. 2Q12-060 revised Landscape Manual Policies and Requirements. ADOPTING the 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). CMC 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 those specified in the existing City of Carisbad Landscape Manual Polices and Requirements (landscape manual). However, it also mandates new water conservation requirements to establish a "water budget" and prepare a water efficient landscape worksheet and documentation package. The update to the city's landscape manual is a follow up item that removes the technical equations, requirements and procedures from Chapter 18.50 and combines them with the existing landscape manual's policies, requirements and guidelines. The resulting document is a new re-formatted landscape manual with a 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 private projects) for mylars: - The City will no longer store mylars of landscape plans. - Digital copies of the approved plans will be available on the City's Document Management System (DMS). • Eliminate the requirement (for private projects) for "as built" construction and planting plans: - CMWD requires irrigation as-built plans due to the use (or potential use) of recycled water. Final approval of landscape installations can occur sooner. • Provide flexibility for projects that incorporate Low Impact Development (LID) features. DEPARTMENT CONTACT: Barbara Kennedy 760-602- 4626 barbara.kennedv(S^carisbadca.gov FOR CITY CLERKS USE ONLY. COUNCIL ACTION: APPROVED CONTINUED TO DATE SPECIFIC • DENIED CONTINUED TO DATE UNKNOWN • CONTINUED • RETURNED TO STAFF • WITHDRAWN • OTHER-SEE MINUTES • AMENDED • Page 2 The draft landscape manual was prepared with input from various city departments and was circulated to the water districts serving Carisbad, landscape architects, and other professionals in the construction and development industry. On January 18, 2012 the Planning Commission reviewed the draft landscape manual and provided feedback to staff. Subsequently, staff presented the draft landscape manual to the Parks and Recreation Commission at their January 30, 2012 meeting. No changes were suggested. Neither of the commissions are required to take a formal action on the proposed landscape manual revisions or on the municipal code amendment. A list of the Planning Commission's recommendations is included as Exhibit 5. Unless noted othenA/ise in Exhibit 5, all of the recommended revisions have been incorporated into the final draft landscape manual dated February 2012. Excerpts of the minutes from both meetings are attached. FISCAL IMPACT: The Planning Division currently contracts with a consultant for landscape plan check services. This service is paid for by the applicant/developer through a plan check fee that is based on the square footage and type of landscape plan. It is not anticipated that the revisions to the landscape manual will increase plan check fees. 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. EXHIBITS: 1. City Council Ordinance No. CS-175 (MCA 11-01) 2.

NOW, THEREFORE, the City Council of the City of Carisbad, California, does ordain as follows: Section I: That Chapter 18.50 of the Carisbad Municipal Code is repealed in its entirety and re-enacted as follows: 1 Section II: 2 Chapter 18.50 3 WATER EFFICIENT LANDSCAPE 4 Sections: 18.50.010 Purpose. 5 18.50.020 Authority. 18.50.030 Incorporation of the landscape manual by reference. 6 18.50.040 Findings. 18.50.050 Definitions. 7 18.50.060 Applicability. 18.50.070 Recycled water. 8 18.50.080 Waste water prevention. 18.50.090 Enforcement. 9 18.50.100 Fees. 10 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. 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 legislative amendment AB 1881, 2006 Stats J. 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 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 ig Allowance (MAWA) as an upper limit for water use and reduce water use for landscaping to the lowest practical amount; and 20 5. Encourage water users of existing landscapes to use water efficiently and without waste. 21 18.50.020 Authority. 22 The city planner or designee, shall administer this chapter. 23 18.50.030 Incorporation ofthe landscape manual by reference.

City of Carlsbad Landscape Manual 25 Policies h/indscaping and site design help to produce character and shape the visual image for Carlshad, 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 recogni2ed 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 viabiUty 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. • Opportunities for instaUation of solar energy or utiUzation of passive solar design features 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 not to exceed the maximum water aUowance. • Landscape systems shaU be designed and maintained to be compatible with the naturaUy semi- arid environment in Carlsbad. City of Carlsbad Landscape Manual SECTION 2: POLICIES Water Conservation Policies (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 Imown 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 dwellings 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 features. • Incorporate native and drought tolerant plant materials whenever possible. • Ensure that invasive or noxious plants are not used. • Feature ground cover, shrubs, and trees to screen elements of unsightUness and screen/soften new improvements. • Provide privacy where appropriate. • Accentuate 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 soil erosion and runoff City of Carlsbad Landscape Manual tl SECTION 2: POLICIES • Irrigation plans shaU promote the industry standard for pubUc safety in aU aspects of the irrigation system. F. Streetscape Program Policies • Landscaping shaU accentuate positive, natural, historical, and architectural elements of Carlsbad. • Landscaping shaU be designed toward a goal of providing a pleasing and safe vehicular and pedestrian experience. G. Fire Protection Policies • Landscape treatments shaU be designed to mitigate fire dangers to structures adjacent to hazardous or native vegetation. • Landscape treatments for the purposes of fire protection shaU be performed in a manner which Umits disruption to environmentaUy sensitive areas whUe stiU achieving conformance with the fire protection standards. H. Slope Revegetation/Erosion Control Policies • Erosion potentials shaU be mitigated through erosion control planting/slope revegetation. • Irrigation shaU be designed to apply optimum water to the slope plants without causing erosion. • Plant materials used on slopes shaU be those species that are Imown to have low water requirements and rooting systems of various depths that wiU minimize erosion and soU sUppage. • Plant materials used shaU be compatible in cultural requirements (exposure, soUs, water needs, etc.) and aesthetic appearance to adjacent natural landscapes.

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-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 waUs. Reduce evaporation by using trees to shade the soU 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 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 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 soU. Limit the use of rocks around plants because it wiU make the area hotter. 7. Appropriate Maintenance Use organic fertiUzers and composting to improve soU texture. Replace mulch as it decomposes. Occasional pmning of trees and shrubs to remove dead stems promotes blooming and controls height/spread. Aerate turfgrass areas in the spring and faU. Regularly inspect, maintain and adjust irrigation systems.

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 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 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 5. Encourage water users of existing landscapes to use water efficiently and without waste. 18.50.020 Authority.

Action: The revisions to both sections have been made as recommended: ". .. bv designing, installing and maintaining water efficient landscapes not to exceed consistent with the maximum water allowance." • Clarify that the required number of trees per parking space and percentage of landscape per paved parking area does not apply to parking structures. Action: The underlined text has been added to Section 3.C.13 (page 16): 13. PARKING LOTS AND PERIMETERS (OUTDOOR/AT GRADE) • Recommends that when parking lots on adjacent parcels are used jointly, that there should be some flexibility in the width of the landscape buffer. Action: None. The landscape manual allows the city planner to approve modifications to requirements provided that the modification is justified and that the findings in Section 1 .E (pages 2-3) can be made. Situations such as the one cited by Commissioner Siekmann do not occur often and can be reviewed on a case-by- case basis. Page 1 of 3 m X X w -i Ol Planning Commission Recommendations (January 18, 2012) Commissioner Arnold • See attached recommendations. Action: None. The paragraph recommended for insertion under page 1, "Purpose" is a commentary on the state of California water crisis and is not specific to the "purpose" ofthe landscape manual. Similarly, the recitals recommended for insertion in the draft ordinance amendment for Chapter 18.50 - Water Efficient Landscape are relevant to the state in general, but are not specific to the City of Carlsbad. Commissioner Nygaard • Recommends adding to the Sustainable Landscaping Brochure (Appendix F) a recommendation that homeowners should request a copy ofthe irrigation plans so that future repairs and modifications will be easier. Action: A new bullet point has been added to the Sustainable Landscape Brochure under "Sustainable Irrigation Design" as follows: • Ask for and retain a copy of the irrigation plans to facilitate future repairs and modifications. Chairperson Schumacher • Commented that the changes from the present landscape manual to what is being proposed should be highlighted forthe Parks and Recreation Commission so that they are easier to identify. Action: A list ofthe recommended revisions was provided to the Parks & Recreation Commission. Page 2 of 3 Recommendations from Commissioner Arnold (January 18, 2012) 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 ofCalifornia 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 landscapes 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 of the 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% of the 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: WHEREAS, California's water system is in a crisis, and for the first time in the state's history, the water supply and delivery system may not be able to meet our growing needs; WHEREAS, we face a complex set of problems that threaten the future of California's population, economy and environment, from aging infrastructure to population growth to climate change; WHEREAS, Southern California, in particular, has suffered through a long period of drought, with most ofthe water we use coming from fresh water imports from Colorado, Oregon and Mexico; WHEREAS, more than 40% ofthe total fresh water used in an average California home goes to irrigating our landscape.

MCA 11-01 - WATER EFFICIENT LANDSCAPE MANUAL - Staff presentation of the revised City of Carlsbad Landscape Manual Polices and Requirements. Mr. Neu introduced Agenda Item 3 and stated Associate Planner Barbara Kennedy would make the staff presentation. Ms. Kennedy gave a brief presentation and stated she would be available to answer any questions. Chairperson Schumacher asked if there were any questions of Staff. Commissioner Nygaard asked about the 5,000 square foot residential requirement. Ms. Kennedy stated that the idea was to make it as least restrictive as possible for single family residential home owners and that it is also an effort to keep costs down for home owners. Commissioner L'Heureux asked if the document is available on the city's website. Ms. Kennedy stated yes. Commissioner Siekmann thanked Staff for the hard work that has been put into updating the manual. She asked if the manual talks about the use of pesticides and herbicides and its effect on run-off. Ms. Kennedy stated the City's Storm Water web page refers to it and that there was a suggestion to place information in the maintenance section of the manual. Commissioner Siekmann commented that Section 1 page 1, and Section 2 page 7, should read "not to exceed the maximum water allowance." Commissioner Arnold suggested that language be added to underscore just how great the water shortage is. He suggested the following paragraph be added under "Purpose": "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 of the water we use comes from fresh water imports from California, Colorado and Mexico. We are approaching a water chsis, and studies have shown that more than 40% of the total fresh water used in an average California home goes to irrigating our landscape." Commissioner Arnold also recommended that similar language should be incorporated into the recitals of the resolution for the landscape manual. Commissioner L'Heureux asked how much is changed from the existing requirements. Ms. Kennedy stated that in essence it is very similar. Commissioner L'Heureux commented that in his opinion, the amount of landscaping within parking lots seems inadequate. Commissioner L'Heureux asked how the city's criteria compared to other cities. Ms. Kennedy responded that she did not have that information. . Commissioner Nygaard asked about permeable paving parking areas. Ms. Kennedy stated that is one of the options in the manual. Commissioner Nygaard suggested that the manual should include a recommendation to home owners to ask for a copy of the irrigation plan so that future repairs and modifications would be easier. Commissioner Siekmann asked about the buffer between adjacent parking lots and if landscaping and trees were required for parking ramps. Ms. Kennedy stated that the requirements applied to on-grade parking. Chairperson Schumacher suggested that the changes to the landscape manual be highlighted for the Parks and Recreation Commission so they are easier to identify. Chairperson Schumacher thanked Staff for their presentations. COMMISSION COMMENTS None. 13 EXHIBIT 7 DRAFT Parks and Recreation Commission - 2 - January 30, 2012 PUBLIC OPEN FORUM Patrice Smerdu, a Carlsbad resident, spoke on the Carlsbad's Community Garden and invited the commission to come out and see the community garden with its recent improvements which include fencing, landscaping in the front, a kiosk, and a compost for gardeners.
