The council of the city finds and determines that:
A. 
Water is a limited resource, particularly in dry years, and must be managed and used efficiently;
B. 
Precipitation in California fluctuates annually causing yearly variations in the water supply as demonstrated by water supply shortages experienced in the East Bay Municipal Utility District service area;
C. 
State and local standards for water use have been established in regard to other water uses, including indoor plumbing fixtures;
D. 
In addition to these water-conserving efforts, landscapes should be designed based on the functional use of the landscape and appropriate horticulture, by including plants best suited for the climate. Use of native California plants shall be encouraged wherever possible;
E. 
Cities as water users can provide leadership in water-conserving landscape and irrigation practices, and more comprehensive water savings can be achieved if the city adopts landscape requirements for use in its own landscape irrigation activities;
F. 
Such landscape requirements do not increase the cost of landscaping when computed over the life of the development and do not diminish the aesthetic quality of the landscaping; and
G. 
Outdoor landscaping can consume up to half of the water used by households and it is well established that frequent overwatering of landscaping can be avoided through appropriate use of plant materials, efficient irrigation systems and good landscape management practices.
H. 
In 2015, the California Department of Water Resources revised its Model Water Efficiency Landscape Ordinance to increase water efficiency standards for new and retrofitted landscapes through encouraging the use of more efficient irrigation systems, graywater usage, and onsite stormwater capture, and by limiting the portion of landscapes that can be covered in turf, and this update is contained in California Code of Regulations, Title 23, Division 2, Chapter 2.7, Model Water Efficient Landscape Ordinance.

The following words and phrases have the meanings ascribed to them in this section:
“Anti-drain valve” or “check valve”
means a valve located under a sprinkler head to hold water in the system so it minimizes drainage from the lower elevation sprinkler heads.
“Application rate”
means the depth of water applied to a given area, usually measured in inches per hour.
“Applied water”
means the portion of water supplied by the irrigation system to the landscape.
“Automatic controller”
means a mechanical or solid-state timer, capable of operating valve stations to set the days and length of time of a water application.
“Backflow prevention device”
means a safety device used to prevent pollution or contamination of the water supply due to the reverse flow of water from the irrigation system.
“Ecological restoration project”
means a project where the site is intentionally altered to establish a defined, indigenous, historic ecosystem.
“Flow rate”
means the rate at which water flows through pipes and valves (gallons per minute or cubic feet per second).
“Hydrozone”
means a portion of the landscaped area having plants with similar water needs that are served by a valve or set of valves with the same schedule. A hydrozone may be irrigated or nonirrigated. For example, a naturalized area planted with native vegetation that will not need supplemental irrigation once established is a nonirrigated hydrozone.
“Infiltration rate”
means the rate of water entry into the soil expressed as a depth of water per unit of time (inches per hour).
“Landscaped area”
means the entire parcel less the building footprint, driveways, nonirrigated portions of parking lots, hardscapes (such as decks and patios), and other nonporous areas. Water features are included in the calculation of the landscaped areas. Areas dedicated to edible plants, such as orchards or vegetable gardens, are not included.
“Mulch”
means any material such as leaves, bark, straw or other materials left loose and applied to the soil surface to reduce evaporation.
“Overspray”
means the water which is delivered beyond the landscaped area, wetting pavements, walks, structures or other nonlandscaped areas.

“Recycled water,” “reclaimed water,” or “treated sewage effluent water”
means treated or recycled waste water of a quality suitable for nonpotable uses such as landscape irrigation that is not intended for human consumption.
“Rehabilitated landscape”
means any relandscaping project that requires a permit.
“Runoff”
means water which is not absorbed by the soil or landscape to which it is applied and flows from the area. For example, runoff may result from water that is applied at too great a rate (application rate exceeds infiltration rate) or when there is a severe slope.
“Soil moisture sensing device”
means a device that measures the amount of water in the soil.
“Soil texture”
means the classification of soil based on the percentage of sand, silt and clay in the soil.

Bermudagrass, kikuyugrass, seashore paspalum, St. Augustine grass, zoysiagrass, and buffalo grass are warm-season grasses.
“Valve”
means a device used to control the flow of water in the irrigation system.

Sensors (rain, freeze, wind, etc.), either integral or auxiliary, that suspend or alter irrigation operation during unfavorable weather conditions are required on all irrigation systems, as appropriate for local climatic conditions. Irrigation should be avoided during windy or freezing weather or during rain.
e.

Allowable irrigation within the setback from nonpermeable surfaces may include drip, drip line, or other low flow nonspray technology. The surfacing of the setback may be mulch, gravel, or other porous material. These restrictions may be modified if:
i. 
The landscape area is adjacent to permeable surfacing and no runoff occurs;
ii. 
The adjacent nonpermeable surfaces are designed and constructed to drain entirely to landscaping; or
