Exhibits: 1. Ordinance Exhibit A: Chapter 17.07 2. Worksheet Examples and Sample Calculations 2 EXHIBIT 2 WORKSHEET EXAMPLES AND SAMPLE CALCULATIONS Water Efficient Landscape Worksheet. Water budget calculations shall adhere to the following requirements: (1) The plant factor used shall be from WUCOLS. The plant factor ranges from 0 to 0.3 for low water use plants, from 0.4 to 0.6 for moderate water use plants, and from 0.7 to 1.0 for high water use plants. (2)All water features shall be included in the high water use hydrozone and temporarily irrigated areas shall be included in the low water use hydrozone. (3)All Special Landscape Areas shall be identified and their water use calculated as described below. (4)ETAF for Special Landscape Areas shall not exceed 1.0. (c) Maximum Applied Water Allowance The Maximum Applied Water Allowance shall be calculated using the equation: MAWA=(ETo) (0.62) [(0.7 x LA)+ (0.3 x SLA)] The example calculations below are hypothetical to demonstrate proper use of the equations and do not represent an existing and/or planned landscape project. The ETo values used in these calculations are from the Reference Evapotranspiration Table in Appendix A, for planning purposes only. For actual irrigation scheduling, automatic irrigation controllers are required and shall use current reference evapotranspiration data, such as from the California Irrigation Management Information System (CIMIS), other equivalent data, or soil moisture sensor data. (1) Example MAWA calculation: a hypothetical landscape project in Fresno, CA with an irrigated landscape area of 50,000 square feet without any Special Landscape Area(SLA= 0,no edible plants, recreational areas, or use of recycled water). To calculate MAWA, the annual reference evapotranspiration value for Fresno is 51.1 inches as listed in the Reference Evapotranspiration Table in Appendix A. MAWA= (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)] MAWA=Maximum Applied Water Allowance (gallons per year) ETo = Reference Evapotranspiration(inches per year) 0.62 = Conversion Factor(to gallons) 0.7 =ET Adjustment Factor(ETAF) LA = Landscape Area including SLA (square feet) 0.3 =Additional Water Allowance for SLA SLA = Special Landscape Area(square feet) MAWA=(51.1 inches) (0.62) [(0.7 x 50,000 square feet) + (0.3 x 0)] = 1,108,870 gallons per year To convert from gallons per year to hundred-cubic-feet per year: = 1,108,870/748 = 1,482 hundred-cubic-feet per year (100 cubic feet=748 gallons) (2) In this next hypothetical example, the landscape project in Fresno, CA has the same ETo value of 51.1 inches and a total landscape area of 50,000 square feet. Within the 50,000 square foot project,there is now a 2,000 square foot area planted with edible plants. This 2,000 square foot area is considered to be a Special Landscape Area. 1 EXHIBIT 2 MAWA=(ETo)(0.62) [(0.7 x LA)+ (0.3 x SLA)] MAWA= (51.1 inches) (0.62) [(0.7 x 50,000 square feet)+(0.3 x 2,000 square feet)] =31.68 x [35,000+600] gallons per year =31.68 x 35,600 gallons per year =1,127,808 gallons per year or 1,508 hundred-cubic-feet per year (d)Estimated Total Water Use. The Estimated Total Water Use shall be calculated using the equation below. The sum of the Estimated Total Water Use calculated for all hydrozones shall not exceed MAWA. ETWU =(ETo)(0.62)I l P IxM4 +SLA) Where: ETWU=Estimated Total Water Use per year(gallons) ETo =Reference Evapotranspiration(inches) PF =Plant Factor from WUCOLS (see Section 17.07.140(ww)) HA =Hydrozone Area[high, medium, and low water use areas] (square feet) SLA =Special Landscape Area(square feet) 0.62 =Conversion Factor IE =Irrigation Efficiency(minimum 0.71) (1)Example ETWU calculation: landscape area is 50,000 square feet; plant water use type,plant factor, and hydrozone area are shown in the table below. The ETo value is 51.1 inches per year. There are no Special Landscape Areas (recreational area,area permanently and solely dedicated to edible plants, and area irrigated with recycled water) in this example. Plant Hydrozone Plant Water Factor Area(HA) PF x HA Hydrozone Use T s (PF)* (square feet (square feet I High 0.8 7,000 5,600 2 High 0.7 10,000 7,000 3 Medium 0.5 16,000 8,000 4 Low 0.3 7,000 2,100 5 Low 0.2 10,000 2,000 Sum 24,700 *Plant Factor from WUCOLS ETWU=(51.1)(0.6224,700+0� = 1,102,116 gallons per year 0.71 Compare ETWU with MAWA: For this example MAWA=(51.1) (0.62) [(0.7 x 50,000)+(0.3 x 0)] = 1,108,870 gallons per year. The ETWU(1,102,116 gallons per year) is less than MAWA (1,108,870 gallons per year). In this example, the water budget complies with the MAWA. 2 EXHIBIT 2 (2)Example ETWU calculation: total landscape area is 50,000 square feet, 2,000 square feet of which is planted with edible plants. The edible plant area is considered a Special Landscape Area (SLA). The reference evapotranspiration value is 51.1 inches per year. The plant type, plant factor, and hydrozone area are shown in the table below. Plant Hydrozone Plant Water Factor Area(HA) PF x HA H drozone Use Type(s)() (PF)* (square feet) (square feet 1 High 0.8 7,000 5,600 2 High 0.7 9,000 6,300 3 Medium 0.5 15,000 7,500 4 Low 0.3 7,000 2,100 5 Low 0.2 10,000 2,000 Sum 23,500 6 SLA 1.0 2,000 2,000 *Plant Factor from WUCOLS ETWU=(51.1)(0.62) 31L0+2,0001 l 0.71 / _(31.68)(33,099+2,000) = 1,111,936 gallons per year Compare ETWU with MAWA. For this example: MAWA=(51.1)(0.62) [(0.7 x 50,000)+(0.3 x 2,000)] =31.68 x [35,000+600] =31.68 x 35,600 =1,127,808 gallons per year The ETWU(1,111,936 gallons per year)is less than MAWA(1,127,808 gallons per year). For this example,the water budget complies with the MAWA. 3 EXHIBIT 2 Reference Evapotranspiration (ETo) Table for the City of San Bernardino.

Homeowner-installed and/or homeowner-hired single-family and multi-family residential projects with a total project landscape area equal to or greater than 5,000 square feet; Q 1 EXHIBIT A B. Limited Applicability. Existing landscapes, cemeteries and certain Special Landscape Areas are exempt from some provisions of this Chapter, as follows: 1. Existing landscapes installed before January 1, 2010 and exceeding 1 acre in area are subject only to water waste prevention and efficient irrigation requirements of Sections 17.07.120 and 17.07.130. 2. New cemeteries or cemetery expansion projects exceeding 2.500 square feet in landscape area shall be subject to the Water Efficient Landscape worksheet requirement and the irrigation analysis and maintenance requirements of Section 17.07.090 and Section 17.07.100. 3. New development or rehabilitation of landscapes including Special Landscape Areas (SLA's), such as edible landscapes, landscapes irrigated with recycled water, and active parks or sport field landscaping shall be subject to the provisions of this Ordinance, except that the Maximum Applied Water Allowance (MAWA) shall be adjusted to provide for adequate irrigation of SLA's. C. Exemptions. The provisions of this Chapter shall not apply to the following exempt landscapes: 1. Registered local, state or federal historical sites; 2. Ecological restoration projects that do not require permanent irrigation systems; 3. Mined land restoration projects that do not require permanent irrigation systems; 4. Botanical gardens and arboretums open to the public. 17.07.030 Landscape Design Standards and Planning Guidelines For the efficient use of water, landscapes shall be carefully designed and planned to thrive in local soil and climatic conditions and to suit the intended function of the project. The following design guidelines shall also be considered in landscape planning: A. Plant Selection: 1. Native plants and drought-tolerant species are encouraged to promote low- maintenance, water efficient landscapes. 2. Any plant may be used in the landscape, provided that the EAWU (estimated annual applied water use) does not exceed the MAWA (maximum annual applied water allowance). 3. Plants with similar water use requirements shall be grouped together in "hydrozones" whenever possible. C 2 EXHIBIT A 4. Turf areas should be minimal, limited mainly to active recreation areas and small lawns. Where turf is used, it should not be planted on slopes greater than 4:1, and warm season varieties are preferred. 5. Fire resistant plant species and fuel modification requirements shall be the top priority for landscape design in high fire hazard areas. 6. Invasive plant species should be avoided, especially near natural areas, fuel modification zones, parks and water bodies. 7. The use of mulch is encouraged to retain moisture. 8. Plant placement shall be planned to create shade in summer and permit solar gain in winter. 9. Plant size and root characteristics at maturity should be considered in plant selection and placement, to avoid damage to property or infrastructure. B. Water Features: 1. Recirculating water systems shall be used for all decorative water features. 2. If available, recycled water should be used in decorative water features, except pools and spas. 3. The surface area of a water feature shall be included in the MAWA calculation with an evaporation rate equivalent to that of a high water use plant. 4. Pool and spa covers are highly recommended. C. Content Requirements of Landscape Design Plans: 1. Each hydrozone shall be identified as a "low", "moderate", "high" or "mixed" water use zone. 2. Landscape areas with unique water budget considerations, such as recreation areas, areas dedicated to edible landscapes, and areas to be irrigated with recycled water shall be delineated. 3. Areas planned for soil amendments, mulch application, surface water features and hardscapes (pervious and impervious) shall be delineated with applicable notes regarding installation and design. 4. On-site design measures for storm water quality management shall be identified to demonstrate consistency with the corresponding Water Quality Management Plan (WQMP). 17.07.040 Irrigation Requirements A. All irrigation systems shall be designed and maintained to prevent runoff, over- spray, low head drainage and other conditions of water waste. Soil types and infiltration rates shall be considered when designing irrigation systems, and irrigation plans shall be designed to meet specific water needs of each hydrozone, to maximize the efficiency of the irrigation system. 3 EXHIBIT A B. Dedicated (separate) landscape water meters shall be installed at new project sites with landscape areas greater than 5,000 square feet, subject to concurrence of the water purveyor. C. The following equipment shall be required to control water waste in new irrigation systems subject to this Ordinance: 1. Automatic irrigation controllers that utilize evapotranspiration or soil moisture sensor data to adjust the frequency and/or duration of irrigation in response to changing weather conditions; 2. Rain sensors with automatic shut-off features, 3. Anti-drain check valves to prevent low-head drainage in sprinkler heads; 4. Pressure regulators as needed when the static water pressure exceeds the maximum recommended operating pressure; and 5. Manual shut-off valves located as close as possible to the point of connection to the water supply, to minimize water loss in case of an emergency or a routine repair. D. Irrigation Design Standards: 1. The irrigation system shall be designed and installed to conform to the project water budget (MAWA), based on planting plans for the project hydrozones; 2. Overhead irrigation shall not be permitted within a 24-inch setback from any non-permeable surface. Allowable irrigation within such setback areas may include drip, drip line or other low flow, non-spray technology. The setback may be planted or unplanted. The surfacing of the setback may be mulch, gravel, or other porous material. These restrictions 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; or (c) the irrigation designer specifies an alternative design or technology as part of the Landscape Documentation Package, and clearly demonstrates compliance with the requirements of this Ordinance. 3. Slopes greater than 25% shall not be irrigated with an irrigation system with a precipitation rate exceeding 0.75 inches per hour. This restriction may be modified if the irrigation designer specifies an alternative design or technology as part of the Landscape Documentation Package, and clearly demonstrates that no excess runoff or erosion will occur. This demonstration shall be confirmed by an irrigation audit. E. The irrigation plan shall be prepared separate from the landscape planting plan, but it shall be consistent with the planting plan and shall conform to all requirements of this Ordinance. 4 EXHIBIT A F. A Water Management Plan shall be prepared to accompany the irrigation plan, in accordance with the requirements of this Ordinance. The Water Management Plan shall describe the irrigation system in detail, identify parties responsible for maintenance of the irrigation system, and set a plan and schedule for management of the system. G. Recycled Water. Dual water distribution systems allowing irrigation with recycled water are encouraged, and may be required to be installed on new construction sites, at the discretion of the water purveyor, and subject to availability. 17.07.050 Landscape Soil Management and Landscape Grading Requirements A. Soil testing shall be performed after mass grading and prior to landscape installation, to ensure the selection of plant materials that are suitable for the site. The soil analysis shall be incorporated in a soil management plan, including the following: 4. A determination of soil texture, indicating the available water holding capacity; 5. An approximate soil infiltration rate, or a range of infiltration rates; 6. Measures of pH and total soluble salts; and 7. Soil management and amendment recommendations. B. Grading of landscape areas shall be designed to minimize unnecessary soil compaction, erosion and water waste.
