DIRECTOR CITY ATTORNEY CITY MANAGER A3# MTG. 22,215 2/23/16 DEPT. CED CITY OF CARLSBAD AGENDA BILL RECOMMENDED ACTION: Introduce City Council Ordinance No. CS-294 approving Municipal Code Amendment MCA 15- 02 to amend Carlsbad Municipal Code Chapter 18.50— Water Efficient Landscape, and adopt City Council Resolution No. 2016-031 approving an amendment to the Landscape Manual Policies and Requirements (SS 11-03A), for the purpose of consistency with the state's Model Water Efficient Landscape Ordinance. ITEM EXPLANATION: On April 1, 2015 Governor Brown issued Drought Executive Order (EO B-29-15) which directed an update to the state's Model Water Efficient Landscape Ordinance (MWELO) through expedited regulation for additional water conservation on new landscape plans. The California Water Commission approved the revised MWELO on July 15, 2015 with an effective date of December 1, 2015 for local agencies. The significant revisions to the MWELO for new landscape plans include: • New developments with landscapes of 500 square feet or more are subject to the ordinance. The previous threshold ranged from 2,500 square feet to 5,000 square feet. • Dedicated landscape water meters or submeters for residential landscapes over 5,000 square feet or non-residential landscapes over 1,000 square feet. • Irrigation systems are required to have pressure regulators and master shut-off valves and irrigation emission devices must meet national standards for high efficiency sprinklers. • Flow sensors that detect high flow conditions due to'broken pipes or popped sprinkler heads are required for landscapes over 5,000 square feet. • Improvements in on-site stormwater capture with friable soil and compost required in planted areas to maximize water retention and infiltration. • Limiting the portion of landscapes that can be planted with high water use plants. • A prescriptive checklist option for landscapes under 2,500 square feet for simplified compliance. • Reporting requirements for local agencies to report yearly on implementation and enforcement.

FISCAL IMPACT: The Planning Division currently contracts with a consultant for landscape plan check services. This service is paid for by the developer or applicant for a project through a plan check fee that is based on the square footage and type of landscape plan. It is not anticipated that the additional landscape plan requirements will substantially increase plan check fees. ENVIRONMENTAL IMPACT: The proposed amendments are exempt from environmental review under the California Environmental Quality Act (CEQA) pursuant to State CEQA Guidelines Section 15307, which exempts actions taken by regulatory agencies as authorized by state law or local ordinance to assure the maintenance, restoration, or enhancement of a natural resource where the regulatory process involves procedures for protection of the environment. The adoption of amendments to Carlsbad Municipal Code Chapter 18.50 and the Landscape Manual will result in enhancement and protection of water resources, and will not result in cumulative adverse environmental impacts or any other potentially significant impact described in State CEQA Guidelines Section 15300.2. Therefore, the project is exempt from the provisions of CEQA. EXHIBITS: 1. City Council Ordinance No. CS-294 (MCA 15-02) 2.

CASE NAME: WATER EFFICIENT LANDSCAPE ORDINANCE CASE NO.: MCA 15-02 WHEREAS, the California Constitution article X, section 2 and California Water Code section 100 provide that because of conditions prevailing in the state, it is the declared policy that the general welfare requires that water resources of the state shall be put to beneficial use to the fullest extent of which they are capable, the waste or unreasonable use of water shall be prevented, and the conservation of such waters is to be exercised with a view to the reasonable and beneficial use thereof in the interest of the people and public welfare; and WHEREAS, pursuant to California Water Code section 106, it is the declared policy of the state that the use of water for domestic use is the highest use of water and the next highest use is for irrigation; and WHEREAS, Carlsbad Municipal Code Chapter 18.50 provides water efficient landscape standards that implement the California Water Conservation in Landscaping Act; and WHEREAS, on April 1, 20154 Governor Brown issued Drought Executive Order (EO B-29-15), which declared that new expedited actions were needed to reduce the harmful impacts from water shortages and severe drought conditions throughout the state of California; and WHEREAS, EO B-29-15 required the State of California Department of Water Resources to update the state's Model Water Efficient Landscape Ordinance, which is a model ordinance required by the Water Conservation in Landscaping Act; and WHEREAS, on July 15, 2015, the California Water Commission approved the state's updated Model Water Efficient Landscape Ordinance; and WHEREAS, as of December 1, 2015, the state's updated Model Water Efficient Landscape Ordinance is applicable to landscape projects in Carlsbad and other local jurisdictions; and WHEREAS, the recommended amendment to Carlsbad Municipal Code Chapter 18.50 is necessary to ensure consistency with and implement the state's updated Model Water Efficient Landscape Ordinance; and WHEREAS, the City Council did on February 23, 2016 hold a duly noticed public hearing as prescribed by law to consider the recommended amendment to Carlsbad Municipal Code Chapter 18.50; and WHEREAS, at said public hearing, upon hearing and considering all testimony and arguments, if any, of all persons desiring to be heard, said City Council considered all factors relating to MCA 15-02 — WATER EFFICIENT LANDSCAPE ORDINANCE. NOW THEREFORE, the City Council of the City of Carlsbad, California, does ordain as follows: SECTION I: Carlsbad Municipal Code Chapter 18.50 — Water Efficient Landscape is amended to read as follows: Chapter 18.50 WATER EFFICIENT LANDSCAPE Sections: 18.50.010 Purpose. 18.50.020 Authority. 18.50.030 Incorporation of the landscape manual by reference. 18.50.040 Findings. 18.50.050 Definitions. 18.50.060 Applicability. -2- 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 18.50.070 Recycled water. 18.50.080 Water waste prevention. 18.50.090 Enforcement. 18.50.100 Fees. 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 adecjuate 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 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 projects 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 planting 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. -3- 1 2 3 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 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. 5. 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. 18.50.020 Authority. The city planner or designee, shall administer this chapter. 18.50.030 Incorporation of the landscape manual by reference. The City of Carlsbad Landscape Manual Policies and Requirements ("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. 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. 18.50.050 Definitions. A. Whenever the following terms are used in this chapter, they shall have the meaning established by this section: 1. "Building permit" is as defined in Section 18.04.015 of this code. 2. "Compost" means the safe and stable product of controlled biologic decomposition of organic materials that is beneficial to plant growth. 3. "Discretionary permit" means any permit requiring a decision making body to exercise judgment prior to its approval, conditional approval or denial. 4. "ET adjustment factor" (ETAF) means a factor that when applied to reference ETo, adjusts for plant water requirements and irrigation efficiency, two major influences on the amount of water that is required for a healthy landscape. 5. "Evapotranspiration" (ETo) means the quantity of water evaporated from adjacent soil and other surfaces and transpired by plants during a specified time period. "Reference evapotranspiration" means a standard measurement of environmental parameters which affect the water use of plants. ETo is given in inches per day, month, or year and is an estimate of the ETo of a large field of four inches to seven inches tall, cool season turf that is well watered. Reference ETo is used as the basis of determining the MAWA so that regional differences in climate can be accommodated. -4- 6. "Grading permit" means the document issued by the city engineer pursuant to Carlsbad Municipal Code Section 15.16.110. 7. "Graywater" means untreated wastewater that has not been contaminated by any toilet discharge, has not been affected by infectious, contaminated, or unhealthy bodily wastes, and does not present a threat from contamination by unhealthful processing, manufacturing, or operating wastes. "Graywater" includes wastewater from bathtubs, showers, bathroom washbasins, clothes washing machines, and laundry tubs, but does not include wastewater from kitchen sinks or dishwashers. (Health & Safety Code 17922.12). 8. "Homeowner-provided landscaping" means landscaping installed either by a homeowner or a licensed contractor hired by a homeowner for a single-family residence. 9. "Landscaped area" means an area with plants, turfgrass and/or other vegetation. A landscaped area includes a water feature either in an area with vegetation or that stands alone. A landscaped area may also include design features adjacent to an area with vegetation, provided that the features are integrated into the design of the landscape area and the primary purpose of the features are decorative. A landscaped area does not include the footprint of a building, decks, patio, sidewalk, driveway, parking lot or other hardscape. A landscaped area also does not include an area without irrigation designated for non- development such as designated open space or area with existing native vegetation. The landscaped area refers to the area to be landscaped as part of the work for which the current approval by the city is being sought. 10. "Landscape Manual" means the manual, approved by city council Resolution No. 2012-060 as amended from time to time, which establishes specific design criteria and guidance to implement the requieennents of this chapter. 11. "Licensed" means licensed by the State of California. 12. "Maximum applied water allowance" (MAWA) means the maximum allowed annual water use for a specific landscaped area based on the square footage of the area, the ETAF and the reference ETo. 13. "Recycled water," sometimes referred to as reclaimed water, means water obtained from the treatment of domestic water waste which is suitable for direct beneficial use or a controlled use that otherwise would not occur and also meets the highest level in conformance with California Code of Regulations, Title 22, Division 4, Chapter 3 (use of recycled water for irrigation and for impoundments), currently Section 60304 and Section 60305. 14. "Turfgrass" means a groundcover surface of mowed grasses such as Bermuda, bluegrass, fescue, rye, St. Augustine, zoyzia, and other mowed turfgrasses or hybrid derivatives of such turfgrasses that are typically used for a recreational use. 18.50.060 Applicability.

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.

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.

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: WATER EFFICIENT LANDSCAPE (MCA 15-02) PROPOSED TEXT CHANGES TO CARLSBAD MUNICIPAL CODE 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.

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.
