BACKGROUND INFORMATION: Lodi Municipal Code (LMC) Section 17.30.070 "Water Efficient Landscape Requirements" was first introduced during the City Council meeting on February 6, 2013 and adopted on February 20, 2013. On July 15, 2015, the California Water Commission approved the revised Model Water Efficient Landscape Ordinance (MWELO). The State estimates that under the revised MWELO, a typical California landscape will use approximately 20 percent less water than landscape installed per the requirements of the previous ordinance. Staff has reviewed the City's existing LMC and revised Section 17.30.070 to comply with the requirements of the State's MWELO. The changes to be incorporated are briefly described below: • Reduces project size subject to the ordinance from 2,500 square feet to 500 square feet and now includes a "prescriptive compliance option" for those projects between 500 and 2,500 square feet. The prescriptive compliance option is intended to provide a more simple approach that includes basic landscape design standards to reduce water usage. • Updates and expand definitions. • Revises the maximum applied water allowance. This water allowance reduces the landscape area that can be planted with high water use plants. • Revises soil management report requirements for multi -lot projects. Clarifies soil testing frequency for multi -lot projects. • Revises the landscape design plan section to address soil preparation, clarify plant selection, and to prohibit high water use plants in street medians. ■ Revises irrigation design plan section to require high-flow sensors and dedicated landscape meters on residential landscapes over 5,000 square feet and on commercial projects of certain size, and clarifies the standards in which irrigation sprinklers must comply. • Revises graywater systems section. • Adds a storm water and rainwater retention section to encourage additional pervious surfaces such as porous concrete and rainwater retention elements in the landscape design. • Adds a reporting section to require local agencies to report on the implementation and enforcement of the ordinance.

The plan will involve a combination of in-house resources and/or outside consulting services depending on the size and complexity of each project. Staff recommends City Council introduce the ordinance amending Lodi Municipal Code Title 17 "Development Code, "by repealing and re-enacting Section 17.30.070 "Water Efficient Landscape Requirements" in its entirety. FISCAL IMPACT: Staff anticipates the revised MWELO compliance oversight will be performed by a combination of in-house and outside resources. The cost to review, approve, and inspect the projects subject to the MWELO is currently unknown. Plan check and inspection costs will be evaluated as staff gains more experience with the compliance efforts and, if needed, additional plan review fees to recover these costs will be recommended.

Automatic irrigation controllers utilizing either evapotranspiration or soil moisture sensor data utilizing non-volatile memory shall be required for irrigation scheduling in all irrigation systems. iii. If the water pressure is below or exceeds the recommended pressure of the specified irrigation devices, the installation of a pressure regulating device is required to ensure.that the dynamic pressure at each emission device is within the manufacturer's recommended pressure range for optimal performance. (A) If the static pressure is above or below the required dynamic pressure of the irrigation system, pressure - regulating devices such as inline pressure regulators, booster pumps, or other devices shall be installed to meet the required dynamic pressure of the irrigation system. (B) Static water pressure, dynamic or operating pressure, and flow reading of the water supply shall be measured at the point of connection. These pressure and flow measurements shall be conducted at the design stage. If the measurements are not available at the design stage, the measurements shall be conducted at installation. iv. Sensors (rain, freeze, wind, etc.), either integral or auxiliary, that suspend or alter irrigation operation during unfavorable weather conditions shall be required on all irrigation systems, as appropriate for local climatic conditions. Irrigation should be avoided during windy or freezing weather or during rain. V. Manual shut-off valves (such as a gate valve, ball valve, or butterfly valve) shall be required, as close as possible to the point of connection of the water supply, to minimize water loss in case of an emergency (such as a main line break) or routine repair. vi. Backflow prevention devices shall be required to protect the water supply from contamination by the irrigation system. A project applicant shall refer to the applicable city code (i.e., public health) for additional backflow prevention requirements. vii. Flow sensors that detect high flow conditions created by system damage or malfunction are required for all non-residential landscapes and residential landscapes of 5,000 sq. ft. or larger. viii. Master shut-off valves are required on all projects except landscapes that make use of technologies that allow for the individual control of sprinklers that are individually pressurized in a system equipped with low-pressure shut -down features. ix. The irrigation system shall be designed to prevent runoff, low head drainage, overspray, or other similar conditions where irrigation water flows onto non -targeted areas, such as adjacent 15 property, non -irrigated areas, hardscapes, roadways, or structures. X. Relevant information from the soil management plan, such as soil type and infiltration rate, shall be utilized when designing irrigation systems. A. The design of the irrigation system shall conform to the hydrozones of the landscape design plan. xii. The irrigation system must be designed and installed to meet, at a minimum, the irrigation efficiency criteria as described in Section 17.30.070(G) regarding the maximum applied water allowance. xiii.

All sprinkler heads installed in the landscape must document a distribution uniformity low quarter of 0.65 or higher using the protocol defined in ASABE/ICC 802-2014. xiv. It is highly recommended that the project applicant or city inquire with the local water purveyor about peak water operating demands (on the water supply system) or water restrictions that may impact the effectiveness of the irrigation system. xv. In mulched planting areas, the use of low volume irrigation is required to maximize water infiltration into the root zone. xvi. Sprinkler heads and other emission devices shall have matched precipitation rates, unless otherwise directed by the manufacturer's recommendations. xvii. Head-to-head coverage is recommended. However, sprinkler spacing shall be designed to achieve the highest possible distribution uniformity using the manufacturer's recommendations. xviii.

Check valves or anti -drain valves are required systems on all sprinkler heads where low point drainage could occur. xx. Areas less than ten feet in width in any direction shall be irrigated with subsurface irrigation or other means that produce no runoff or overspray. xxi. Overhead irrigation shall not be permitted within twenty-four inches of any non -permeable surface. Allowable irrigation within the setback from non -permeable surfaces may include drip, drip line, or other low flow non -spray technology. The setback area may be planted or unplanted. The surfacing of the setback may be mulch, gravel, or other porous material. These restrictions may be modified if: IV: (A) The landscape area is adjacent to permeable surfacing and no runoff occurs; (B) The adjacent non -permeable surfaces are designed and constructed to drain entirely to landscaping; or (C) The irrigation designer specifies an alternative design or technology, as part of the, landscape documentation package and clearly demonstrates strict adherence to irrigation system design criteria in Section 97.30.070(J)M( )0X).. Prevention of overspray and runoff must be confirmed during the irrigation audit. xxii. Slopes greater than twenty-five percent shall not be irrigated with an irrigation system with an application rate exceeding 0.75 inches per hour.

Refer to Section 17.30.010 (d) for the applicability of this ordinance to landscape areas less than 2,500 square feet with the Estimated Total Water Use met entirely by graywater. S. Stormwater Management and Rainwater Retention. Stormwater management practices minimize runoff and increase infiltration which recharges groundwater and improves water quality. Implementing stormwater best management practices into the landscape and grading design plans to 21 minimize rainwater runoff and to increase on-site retention and infiltration are encouraged. 2. Project applicants shall refer to the city or Regional Water Quality Control Board for information on any applicable stormwater technical requirements. 3. All planted landscape areas are required to have friable soil to maximize water retention and infiltration. Refer to California Code of Regulations Title 23, Chapter 2.7, § 492.6(a). 4. It is strongly recommended that landscape areas be designed for capture and infiltration capacity that is sufficient to prevent runoff from impervious surfaces (i.e., roof and paved areas) from either: (1) the one inch, 24-hour rain event or (2) the 85th percentile, 24-hour rain event, and/or additional capacity as required by any applicable local, regional, state or federal regulation. 5. It is recommended that storm water projects incorporate any of the following elements to improve on-site storm water and dry weather runoff capture and use: a. Grade impervious surfaces, such as driveways, during construction to drain to vegetated areas. b. Minimize the area of impervious surfaces such as paved areas, roof and concrete driveways. C. Incorporate pervious or porous surfaces (e.g., gravel, permeable pavers or blocks, pervious or porous concrete) that minimize runoff. d. Direct runoff from paved surfaces and roof areas into planting beds or landscaped areas to maximize site water capture and reuse. e. Incorporate rain gardens, cisterns, and other rain harvesting or catchment systems. f. Incorporate infiltration beds, swales, basins and drywells to capture storm water and dry weather runoff and increase percolation into the soil. g. Consider constructed wetlands and ponds that retain water, equalize excess flow, and filter pollutants. T. Public Education. 1. Publications. Education is a critical component to promote the efficient use of water in landscapes. The use of appropriate principles of design, installation, management and maintenance that save water is encouraged in the community. a. The city shall provide information to owners of permitted renovations and new, single-family residential homes regarding the design, installation, management, and maintenance of water efficient landscapes based on a water budget. 2. Model Homes. All model homes shall be landscaped and use signs and written information to demonstrate the principles of water efficient landscapes described in this title. a. Signs shall be used to identify the model as an example of a water efficient landscape featuring elements such as hydrozones, irrigation equipment, and others that contribute to the overall water efficient theme. Signage shall include information about the site water use as designed 22 per the local ordinance; specify who designed and installed the water efficient landscape; and demonstrate low water use approaches to landscaping such as using native plants, graywater systems, and rainwater catchment systems. b. Information shall be provided about designing, installing, managing, and maintaining water efficient landscapes. U. Provisions for Existing Landscapes. The city may by mutual agreement designate another agency, such as a water purveyor, to implement some or all of the requirements contained in this title. Local agencies may collaborate with water purveyors to define each entity's specific responsibilities relating to this title. V. Irrigation Audit, Irrigation Survey, and Irrigation Water Use Analysis. 1. This section shall apply to all existing landscapes that were installed before December 1, 2015 and are over one acre in size. a. For all landscapes that have a water meter, the city shall administer programs that may include, but not be limited to, irrigation water use analyses, irrigation surveys, and irrigation audits to evaluate water use and provide recommendations as necessary to reduce landscape water use to a level that does not exceed the maximum applied water allowance for existing landscapes. The maximum applied water allowance for existing landscapes shall be calculated as: MAWA = (0.8) (ETo)(LA)(0.62). b. For all landscapes that do not have a meter, the city shall administer programs that may include, but not be limited to, irrigation surveys and irrigation audits to evaluate water use and provide recommendations as necessary in order to prevent water waste. 2. All landscape irrigation audits shall be conducted by a certified landscape irrigation auditor. W. Water Waste Prevention. 1. The city shall prevent water waste resulting from inefficient landscape irrigation by prohibiting runoff from leaving the target landscape due to low head drainage, overspray, or other similar conditions where water flows onto adjacent property, non -irrigated areas, walks, roadways, parking lots, or structures. Penalties for violation of these prohibitions shall be established locally. 2. Restrictions regarding overspray and runoff may be modified if: a. The landscape area is adjacent to permeable surfacing and no runoff occurs; or b. The adjacent non -permeable surfaces are designed and constructed to drain entirely to landscaping. X. Effective Precipitation. The city considers effective precipitation (twenty-five percent of annual precipitation) in tracking water use and uses the following equation to calculate maximum applied water allowance: MAWA= (ETo - Eppt) (0.62) [(0.7 x LA) + (0.3 x SLA)] for residential areas. MAWA= (ETo - Eppt) (0.62) [(0.45 x LA) + (0.55 x SLA)] for non-residential areas. 23 SECTIDN 2. No Mandatory Duty of Care: This ordinance is not intended to and shall not be construed or given effect in a manner which imposes upon the City, or any, officer or employee thereof, a mandatory duty of care towards {persons or property within the City or outside of the City so as to provide a basis of civil liability for damages, except as otherwise imposed by law.
