SECTION 2: Amendment to Title 15. Irwindale Municipal Code Title 15
"Buildings and Construction" is amended to add Chapter 15.30 "Water Efficient
Landscape Standards and Guidelines" to read as follows:
WATER EFFICIENT LANDSCAPE STANDARDS AND GUIDELINES
Sections:
15.30.010 Purpose.
The purpose of this Chapter is to establish water efficient landscape regulations
that are acceptable under Governor Brown's April 1, 2015 Drought Executive Order (B-
29-15) and that are at least as effective in conserving water as the State Model Water
Efficient Landscape Ordinance, in the context of conditions in the City, in order to
ensure that landscapes are planned, designed, installed, maintained, and managed in a
manner that uses water efficiently, encourages water conservation, and prevents water
waste. The provisions of this Chapter shall be deemed to be controlling over the
subject matter herein in the event of any conflict between this Chapter and any other
provision in the Municipal Code.
Ordinance No. 701

16.30.020 Definitions.
For the purposes of this Chapter and the Guidelines for the implementation of
this Chapter, the following terms are defined:
"City" means the City of Irwindale.
"City Manager" means the City Manager of the City or his or her designee.
"Aggregate landscape area" means the area undergoing development as one
project for production home neighborhoods or other situations where multiple parcels
are undergoing development as one project, but will eventually be individually owned.
"Applicant" means the person submitting a landscape documentation package.
Applicants can be the property owner or his or her designee.
"Applied water" means the portion of water supplied by the irrigation system to
the landscape.
"Budget-based tiered-rate structure" means tiered or block rates for irrigation
accounts charged by the local water purveyor(s) in which the block definition for each
customer is derived from lot size or irrigated area and the evapotranspiration
requirements of landscaping.
"Ecological restoration project" means a project where the site is intentionally
altered to establish a defined, indigenous, historic ecosystem.
"Estimated Applied Water Use" or "EAWU" means the average annual total
amount of water estimated to be necessary to keep plants in a healthy state, calculated
as provided in the Guidelines. It is based on the reference evapotranspiration rate, the
size of the landscape area, plant water use factors, and the relative irrigation efficiency
of the irrigation system.
"Evapotranspiration adjustment factor" or "ET adjustment factor" or "ETAF"
means a measurement equal to the plant factor divided by the irrigation efficiency factor
for a landscape project, as described in the Guidelines. The ETAF is calculated in the
context of local reference evapotranspiration, using site-specific plant factors and
irrigation efficiency factors that influence the amount of water that needs to be applied to
the specific landscaped area.
"Guidelines" refers to the Guidelines for Implementation of the Water Efficient
Landscape Ordinance, as approved by the City, which describes procedures,
calculations, and requirements for landscape projects subject to this Chapter.
Ordinance No. 701

"Hardscapes" means any durable material or feature (pervious and non-pervious)
installed in or around a landscaped area, such as pavements or walls. Pools and other
water features are considered part of the landscaped area and are not considered
hardscapes.
"Irrigation efficiency" or "IE" means the measurement of the amount of water
beneficially used divided by the amount of water applied to the landscaped area.
Irrigation efficiency is derived from measurements and estimates of irrigation system
characteristics and management practices. The minimum irrigation efficiency for
purposes of this Chapter are 0.75 for overhead spray devices and 0.81 for drip systems.
"Landscaped area" means all the planting areas, turf areas, and water features in
a landscape design plan subject to the Maximum Applied Water Allowance and
Estimated Applied Water Use calculations. The landscaped area does not include
footprints of buildings or structures, sidewalks, driveways, parking lots, decks, patios,
gravel or stone walks, other pervious or non-pervious hardscapes, and other non-
irrigated areas designated for non-development (e.g., open spaces and existing native
vegetation).
"Landscape contractor" means a person licensed by the State of California to
construct, maintain, repair, install, or subcontract the development of landscape
systems.
"Landscape documentation package" means the documents required to be
provided to the City for review and approval of landscape projects subject to this

project, as provided in the definition of "landscaped area," meeting the requirements
under Section 15.30.030 of this Chapter.
"Landscape rehabilitation" means any re-landscaping project that meets the
applicability criteria of Section 15.30.030(A) of this Chapter, where the aggregate
modified landscape area is equal to or greater than 2,500 square feet or where the
cumulative modified area is equal to or greater than 2,500 square feet if the
modifications are planned to occur incrementally within one year.
"Landscape System" means a defined plan of landscaping and irrigation to be
designed and implemented for a development project.
"Local agency" means a city or county, including a charter city or charter county,
or local water purveyor that is authorized by the City to implement, administer, and/or
enforce any of the provisions of this Chapter on behalf of the City. The local agency
may be responsible for the enforcement or delegation of enforcement of this Chapter

inspection of a landscape project.
"Local water purveyor" means any entity, including a city, county, public agency,
or private water company that provides retail water service. Local water purveyor shall
also mean any entity that provides wholesale water service, for the purpose of Section
15.30.040(B) and Section 15.30.070.
"Maximum applied water allowance" or "MAWA" means the upper limit of annual
applied water for the landscaped area as specified in Section 2.2 of the Guidelines. It is
based upon the area's reference evapotranspiration, the ET adjustment factor and the
size of the landscaped area. The Estimated Applied Water Use shall not exceed the
MAWA. MAWA = (ETo) (0.62) [(ETAF x LA) + ((1-ETAF) x SLA)]
"Mined-land or reclamation projects" means any surface mining operation with a
reclamation plan approved in accordance with the Surface Mining and Reclamation Act
of 1975.
"New landscape" means a new building with a landscape or other new landscape
such as a park, playground, or greenbelt without an associated building.
"Non-pervious" means any surface or natural material that does not allow for the
passage of water through the material and into the underlying soil.
"Person" means any individual, firm, joint venture, joint stock company,
partnership, public or private association, company, corporation, business trust,

manager, agent, officer, or employee thereof, or any other entity which is recognized by
law as the subject of rights or duties.
"Pervious" means any surface or material that allows the passage of water
through the material and into the underlying soil.
"Permit" means an authorizing document issued by a local agency for new
construction or rehabilitated landscape.
"Plant factor" or "plant water use factor" means a factor, when multiplied by ETo,
that estimates the amount of water needed by plants. For purposes of this Chapter, the
plant factor range for very low water use plants is 0 to 0.1; the plant factor for low water
use plants is 0 to 0.3; the plant factor range for moderate water use plants is 0.4 to 0.6;
and the plant factor range for high water use plants is 0.7 to 1.0. Plant factors cited in
this Chapter are derived from the publication "Water Use Classification of Landscape
Species." Plant factors may also be obtained from horticultural researchers from
academic institutions or professional associations as approved by the California
Department of Water Resources (DWR).
Ordinance No. 701

"Recycled water" means treated or recycled waste water of a quality suitable for
non-potable uses such as landscape irrigation and water features. This water is not
intended for human consumption.
"Reference evapotranspiration" or "ETo" means a standard measurement of
environmental parameters which affect the water use of plants. ETo is expressed in
inches per day, month, or year as represented in the Guidelines, and is an estimate of
the evapotranspiration of a large field of four-to seven-inch tall, cool-season grass that
is well watered. Reference evapotranspiration is used as the basis of determining the
Maximum Applied Water Allowances.
"Smart automatic irrigation controller" means an automatic irrigation controller
utilizing either evapotranspiration or soil moisture sensor data with non-volatile memory
required for irrigation scheduling in all irrigation systems, recommending U.S. EPA
WaterSense labeled devices as applicable,
"Special landscape area" or "SLA" means an area of the landscape dedicated
solely to edible plants such as orchards and vegetable gardens; areas irrigated with
recycled water; water features using recycled water; and recreational areas dedicated to
active play where turf provides a playing surface, such as parks, sports fields, golf
courses, and where turf provides a playing surface.
"Turf" means a ground cover surface of mowed grass. Annual bluegrass,
Kentucky bluegrass, Perennial ryegrass, Red fescue, and Tall fescue are cool-season
grasses. Bermudagrass, Kikuyugrass, Seashore Paspalum, St. Augustinegrass,
Zoysiagrass, and Buffalo grass are warm-season grasses.
"Valve" means a device used to control the flow of water in an irrigation system.
"Water feature" means a design element where open water performs an
aesthetic or recreational function. Water features include ponds, lakes, waterfalls,
fountains, artificial streams, spas, and swimming pools (where water is artificially
supplied). The surface area of water features is included in the high water use
hydrozone of the landscaped area. Constructed wetlands used for on-site wastewater
treatment, habitat protection or storm water best management practices that are not
irrigated and used solely for water treatment or storm water retention are not water
features and, therefore, are not subject to the water budget calculation.
15.30.030. Applicability.
A. Beginning February 1, 2016 and consistent with Executive Order No. B-29-15,
this Chapter applies to the following landscape projects:
Ordinance No. 701
Page 6
1. New landscape projects with an aggregate landscape area equal to or greater
than 500 square feet, requiring a building or landscape permit, plan check or
design review;
2. Rehabilitated landscape projects with an aggregate landscape area equal to
or greater than 2,500 square feet, requiring a building permit or landscape
permit, plan check or design review;
3. New or rehabilitated landscape projects with an aggregate landscape area of
2,500 square feet or less may comply with the performance requirements of
this Ordinance or conform to the prescriptive measures contained in Appendix
A of the Guidelines.
4. New or rehabilitated projects using treated or untreated graywater or
rainwater capture on site, any lot or parcels within the project that has less
than 2,500 square feet of landscape area and meets the lot or parcel's
landscape water requirement (Estimated Total Water Use) entirely with the
treated or untreated graywater or though stored rainwater capture on site is
subject only to Appendix A of the Guidelines.
B. Section 15.30.060(B) of this Chapter regarding water waste applies to:
1. All landscaped areas, whether installed prior to or after January 1, 2010; and
2. All landscaped areas installed after February 1, 2016 to which Section
13.08.030(A) is applicable.
15.30.040. Exemptions.
A. This Chapter does not apply to:
1. Registered local, state, or federal historical sites;
2. Ecological restoration projects that do not require a permanent irrigation
system;
3. Mined-land reclamation projects that do not require a permanent irrigation
system; or
4. Plant collections, as part of botanical gardens and arboretums open to the
public,
B. The requirements of this Chapter may be partially or wholly waived, at the
discretion of the City Manager, for landscape rehabilitation projects that are
limited to replacement of plantings with equal or lower water needs and where
any modifications to the irrigation system do not require ministerial permits and
Ordinance No. 701
Page 7
the irrigation system is found to be designed, operable, and programmed
consistent with minimizing water waste in accordance with local water
purveyor(s)' regulations or programs.
15.30.050. Implementation Procedures.
A. A Landscape Documentation Package is required to be submitted to the City for
review and approval prior to the issuance of permits and prior to the start of
construction. Any Landscape Documentation Package submitted to the City
must comply with provisions of this Chapter and the Guidelines.
B. The Landscape Documentation Package must include a certification by a
landscape professional stating that the landscape design plan, soil management
report, irrigation design plan, and water calculations have been prepared by or
under the supervision of the landscape professional and are certified to be in
compliance with the provisions of this Chapter.
1. Landscape and irrigation plans must be submitted to the City for review and
approval with appropriate water use calculations. Water use calculations
must be consistent with calculations contained in the Guidelines.
2. A Certification of Completion is required to verify compliance with the
approved plans and must be obtained in conjunction with a Certificate of Use
and Occupancy or a Permit Final, as provided in the Guidelines.
15.30.060. Landscape Water Use Standards.
A. For applicable new landscape or landscape rehabilitation projects subject to
Section 15.30.030(A) of this Chapter, the Estimated Applied Water Use allowed
for the landscaped area may not exceed the MAWA calculated using an ET
adjustment factor of 0.7, except for the portion of the MAWA applicable to any
special landscape areas within the landscape project, which may be calculated
using an ETAF of 1.0. Where the design of the landscaped area can be
otherwise shown to be equivalently water efficient, the applicant may submit
alternative or abbreviated information supporting the demonstration that the
annual EAWU is less than the MAWA, at the discretion of and review and
approval of the City.
B. Irrigation of all landscaped areas must be conducted in a manner conforming to
the rules and requirements of this Chapter, and is subject to penalties and
incentives for water conservation and water waste prevention as determined and
implemented by the local water purveyor(s) or as mutually agreed by local water
purveyor(s) and the City.
