Milpitas Municipal Code Ch. 5 Water Efficient Landscapes

Footnotes:

--- (3) ---

Editor's note— Ord. No. 238.4, § 2, adopted December 15, 2015, amended the Code by repealing former Ch. 5, §§ VIII-5-1.01—VIII-5-8.00, and adding a new Ch. 5. Former Ch. 5 pertained to similar subject matter, and derived from Ord. 238, adopted January 5, 1993; Ord. 238.2, adopted August 16, 2005; and Ord. 238.3, adopted August 3, 2010.

The City Council has found:

A. That the limited supply of City waters are subject to ever increasing demands;

B. That the City's economic prosperity depends on adequate supplies of water;

C. That City policy promotes conservation and efficient use of water;

D. That landscapes provide recreation areas, clean the air and water, prevent erosion, offer fire protection, and replace ecosystems displaced by development; and

E. That landscape design, installation, and maintenance can and should be water efficient.

(Ord. No. 238.4, § 2, 12/15/15)

A. Consistent with the 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 designing, installing, and maintaining 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. Establish provisions for water management practices and water waste prevention for established landscapes.

4. Insure efficient landscape irrigation water use. This Chapter is applicable to all new project landscapes 500 square feet or greater, and rehabilitated landscapes 2,500 square feet or greater, all common area landscapes in single-family and multi-family subdivisions or planned unit developments, and all existing landscapes one acre or more in size, irrigated with potable water.

B. Landscapes that are planned, designed, installed, managed and maintained with the watershed based approach can improve California's environmental conditions and provide benefits and realize sustainability goals. Such landscapes will make the urban environment resilient in the face of climatic extremes. Consistent with the findings and 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 esthetic 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;

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.

(Ord. No. 238.4, § 2, 12/15/15)

Landscape water meters, defined as dedicated water service meters, shall be installed for all non-residential irrigated landscapes of 1,000 square feet or greater and residential (including single family) irrigated landscapes of 2,500 square feet or greater. A privately owned meter or submeter is only allowed upon approval of the City Engineer.

d. Controllers. Automatic irrigation control systems utilizing either evapotranspiration or soil moisture sensor data using non-volatile memory shall be required for all irrigation systems and must be able to accommodate all aspects of the design.

e. Valves. Plants which require different amounts of water shall be irrigated by separate valves. Each valve shall irrigate a hydrozone with similar site, slope, sun exposure, soil conditions, and plant materials with similar water use. Where feasible, trees shall be placed on separate valves from shrubs, groundcover and turf. Antidrain (check) valves shall be installed in strategic points to minimize or prevent low-head drainage.

f. Sprinkler heads. Heads and emitters shall have consistent application rates within each control valve circuit. Sprinkler heads shall be selected for proper area coverage, application rate, operating pressure, adjustment capability, and ease of maintenance.

g. 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.

h. Soil Moisture Sensing Devices. It is recommended that soil moisture sensing devices be considered where appropriate.

i. Backflow Prevention Assemblies. Backflow protection shall be in accordance with Chapter 3, Title VIII of the Milpitas Municipal Code which establishes backflow prevention and cross-connection control.

j. Pressure Regulating Devices. 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.

k. Flow Sensors. Flow sensors that detect high flow conditions created by system damage or malfunction are required for all non-residential landscapes and residential landscapes 5,000 square feet or larger.

m. 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.

n. Swing joints or other riser-protection components are required on all risers subject to damage that are adjacent to hardscapes or in high traffic areas of turfgrass.

o. Relevant information from the soil management plan, such as soil typed infiltration rate, shall be utilized with designing irrigation systems.

p. The design of the irrigation system shall conform to the hydrozones of the landscape design plan.

q. The irrigation system must be designed and installed to meet, at a minimum, the irrigation efficiency criteria regarding the Maximum Applied Water Allowance.

r. All irrigation emission devices must meet the requirements set in the American National Standards Institute (ANSI) standard, American Society of Agricultural and Biological Engineers'/International Code Council's (ASABE/ICC) 802-2014 "Landscape Irrigation Sprinkler and Emitter Standard." All sprinkler heads installed in the landscape must document a distribution uniformity low quarter of 0.65 or higher using the protocol defined in ABSABE/ICC 802-2014.

s. Sprinkler heads and other emissions devices shall have matched precipitation rates, unless otherwise directed by the manufacturer's recommendations.

t. Head to head coverage is recommended. However, sprinkler spacing shall be designed to achieve the highest possible distribution uniformity using the manufacturer's recommendations.
