CITY OF SAN BERNARDINO REQUEST FOR COUNCIL ACTION
STAFF REPORT
Subject:
An Ordinance of the City of San Bernardino adding Chapter 17.07 to the Municipal Code as
the City of San Bernardino Water Efficient Landscape Ordinance.
Backl!round:
In August of 2009, the Mayor and Common Council adopted the Water Wise Landscape
Program as Chapter 17.06 of the Municipal Code. This is a voluntary program for conversion of
owner-occupied single-family residential properties to water efficient (water wise) landscaping.
When this voluntary program was presented for approval, the City Attorney's office briefed the
LRC and the full Council on State-mandated water conservation requirements of the Water
Conservation in Landscaping Act of2006 (AB 1881, Laird). AB 1881 requires each local agency
to adopt a water efficient landscape ordinance by. January 1, 2010 and to report to the
Department of Water Resources (DWR) by January 31, 2010 that it has adopted its own
ordinance or that it will comply with the State Model Water Efficient Landscape Ordinance
(MWELO) approved on September 10,2009.
On October 22, 2009, staff attended a workshop given by DWR to guide local agencies
preparing local Water Efficient Landscape Ordinances. Each city and county has three options:
1. Adopt the State's model ordinance (MWELO)
2. Adopt a local ordinance and make a finding that it is at least as effective in conserving
water as the MWELO.
3. Do nothing and the MWELO will apply as ifit were adopted by the local agency.
Each city and county is required to report the status of the local Water Efficient Landscape
Ordinance (WELO) to DWR by January 31, 2010. DWR will not make a determination of
compliance with AB 1881, and will not evaluate the effectiveness of individual ordinances.
DWR will submit a status report to the legislature on January 31, 2011.
In January of this year as the City was exploring cost savings measures and positions were being
eliminated, staffrecommended that the City default to the State's model ordinance as a result. At
that time, the draft model ordinance was not available for review. Over the past few months,
however, staff determined that this would not be the best way to proceed.
Staff is preparing a draft Water Efficient Landscape Ordinance (WELO) to be proposed for
adoption as Chapter 17.07 of the Municipal Code. The proposed WELO would contain the main
provisions of the State model ordinance, including landscape and irrigation design standards and
water budgeting requirements to minimize water use for irrigation. The water budget and other
planning and inspection requirements will apply to all new and rehabilitated landscape areas over
2,500 square feet that would be subject to a landscape plan and pernlit, including public projects.
Local agencies and/or water purveyors are also required to implement measures to prevent water
waste on existing landscapes, especially overspray and runoff. Individual homeowner
landscaping less than 5,000 square feet in area is exempt from the water budget and landscape
2
planning standards. Registered historical sites, botanical gardens, ecological restoration and
mining reclamation projects are also exempt.
Staff will review the requirements of the State model ordinance with the LRC and propose
provisions that the Council may want to tailor to address local conditions in the City's Municipal
Code. Upon adoption of the local ordinance as Municipal Code Chapter 17.07, complementary
revisions to Chapter 19.28 of the Development Code, Landscaping Standards, may be needed
also, at least to reference the water-efficient landscaping standards and the plan review and
inspection process.
Financial Impact:
In order to maintain a neutral financial impact on the City, it will be necessary for several
departments and agencies to cooperate in the implementation of new water efficient landscape
requirements. Plan review and inspection fees may be adjusted to fund required activities.
Identification of water waste and enforcement of water waste regulations may be funded by fines
or through a consumption-based water rate structure.
Recommended Motion:
That the proposed Ordinance be referred to the Legislative Review Committee for its review and
recommendation.

AGENDA ITEM: AN ORDINANCE OF THE CITY QF SAN BERNARDINO
ADDING SAN BERNARDINO MUNICIPAL CODE CHAPTER 17.06,
RELATING TO THE CITY OF SAN BERNARDINO WATER WISE
LANDSCAPE PROGRAM. (Recommended for approval at the Legislative Review
Committee meetiag of July 21, 2009 - Committee Members Present: Brinker,
McCammack, Shorett)
1. Previous Council and Committee Action
This item was previously before the Council as Item No. 47 on the July 6, 2009
agenda. On that date, on the recommendation of staff, the Council referred the matter to
the Legislative Review Committee. The Committee considered the matter on July 7,
2009, and after hearing comments from stafJ' and members of the public, requested
revisions to the item. The Committee considered the revised version of the item on July
21, 2009, and voted to return the item to the Council for further action,
The principal changes to the item slBce July 6 are (I) a participant in the program
who elects to withdraw prior to completion may now do so by paying a fee of$l 00 for
each month the property was covered by the program; and (2) making a false statement in
a program document or displaying an official program sign on property not covered by
the program are specified to be misdemeanors punishable by the penalty set forth in the
Municipal Code (i.e., imprisonment in the county jail not exceeding six months, or a fine
not exceeding one thousand dollars, or both). In addition, after final review of the item
by the City Attorney's Office, it is recommended that the program require owner
occupancy of the subject property, to preclude the potential for abuse ofthe program by
absentee landlords. The revised item incorporates that requirement
2. Description of Item
Lingering drought conditions, combined with environmental restrictions that have
dramatically reduced the amount of water available from Northern California through the
Sacramento-San Joaquin Delta, have led to greater interest in water conservation
measures, In Southern CaJifomia, cities in Imperial, Kern, Los Angeles, Orange,
Riverside, San Bernardino, San Diego, Santa Barbara, and Ventura Counties have
adopted water efficient landscaping programs.
~q
O~-I'3'ZOOq
Currently, 60 to 70 percent of treated drinking water is used to irrigate landscapes.
The most effective way property owners can conserve water is by replacing existing
vegetation, primarily grass, with more drought-tolerant plants.
The accompanying Proposed Ordinance is intended to help owners of single-
family residential property voluntarily convert their grass lawns or other water-intensive
landscaping to drought-tolerant vegetation. The Ordinance provides a procedure for
those owners to obtain a Water Wise Landscaping Permit that would temporarily exempt
their property from the Municipal Code provisions that prohibit dead or dry vegetation,
so that existing vegetation could be retired naturally by discontinuing irrigation.
The replacement vegetation would have to be installed within a specified time
period, and comply with water wise guidelines set forth in the Ordinance. Throughout,
the property would remain subject to restrictions on the accumulation of dry brush as
necessary to prevent fire hazard, and to all other property maintenance requirements,
3. Background - State Regulation of Water Use In Landscape Irrigation
For a number of years, the State of California has required local agencies to
restrict the use of water in landscape irrigation. Until recently, charter cities like San
Bernardino have been exempted from this requirement. This year, however, the
exemption is due to expire.
While the Proposed Ordinance would not be directly affected by the state
requirements, it would operate in tandem with those requirements. Hence, in considering
the Proposed Ordinance it is important to understand the state regulatory framework,
The Water Conservation in Landscaping Act of 1990 (Cal, Gov. Code, ~ 65591 et
seq.), required that each local agency in California either (a) adopt a water efficient
landscape ordinance or (b) adopt findings stating that an ordinance was unnecessary, An
agency that had not done either one by January I, 1993 was automatically subject to a
Model Water Efficient Landscape Ordinance (Model Ordinance) adopted by the
California Department of Water Resources (DWR) in 1992, (See 23 Ca1. Code Regs. ~
490 et seq.) Charter cities, however, were not subject to these requirements. (Gov, Code,
Ii 65594.)
In 2006, the Legislature enacted A.B. 1881. Among other things, A.B. 1881
requires the DWR to update the Model Ordinance, and requires each local agency, not
later than January I, 2010, to adopt the updated Model Ordinance or an equivalent
ordinance. If the agency fails to do either, the Model Ordinance will be deemed to have
been automatically adopted. Further, AB. 1881 Drovidcs that the exemption for charter
cities exoires when the DWR uodates the Model Ordinance,
As of this writing, the DWR has released a draft of the updated Model Ordinance
but has not yet released the final version. Like its predecessor, the draft updated
ordinance provides that specified landscape projects - new or rehabilitated projects of a
- 2-
-,
specified square footage that require a building or landscape permit, plan check, or design
review - must comply with a Maximum Applied Water Allowance (Water Allowance).
The Water Allowance is calculated using a formula that takes into account the
size of the landscaped area, the rate of expected water loss due to evaporation and plant
transpiration under the prevailing local conditions, and an "Adjustment Factor," The
updated draft decreases the Adjustment Factor from 0.8 to 0.71, effectively reducing the
Water Allowance for any given project by a factor of 12 percent.
Neither the existing Model Ordinance nor the updated draft contains any
provision relaxing local property maintenance requirements for landscaping that is in the
process of being converted to a less water-intensive use. The accompanying Proposed
Ordinance is intended to address that matter. Hence, the Proposed Ordinance will
complement, but will not duplicate or overlap with, the updated Model Ordinance or any
equivalent water efficient landscape ordinance that the City may adopt in response to
AB. ]881.
It also should be noted that earlier this year the Inland Empire Landscape
Alliance, a consortiwn of Western San Bernardino County cities and water districts,
developed its own model ordinance in response to the DWR Model Ordinance, which the
Alliance found difficult to interpret and administer. Thc Alliance's model ordinancc is
similar to the DWR's and, according to the Alliance, meets the requirements of A.B.
1881. The Alliancc's model ordinancc is proposed to be adopted as the landscape
ordinance for San Bernardino County. However, that ordinance, like the DWR Model
Ordinance, does not address the matter addressed in the accompanying Proposed
Ordinance,
4. The Proposed Water Wise Landscape OrdiDance
The City's Municipal Code prohibits "dry vegetation of any type;" including "dry
grass," "Iandscapillg constituting an unsightly appearance," and "dead vegetation." The
Code also provides that ''vegetation shall be maintained, including regular irrigation,"
(See SBMC Sections 8.27.010, 8.30.010, 15.24.040.)
Former Council Member Susan Lien Longville. Director of the Water Resources
Institute at CSUSB, has proposed that the City consider modifying the irrigation
requirements to accommodate residential single-family property owners who voluntarily
decide to replace water-intensive vegetation with a Water Wise Landscape. Ms.
Longville notes that the most environmentally sound procedure for retiring water-
intensive landscaping, such as a grass lawn, is to stop watering during the dry part of the
year, allowing the vegetation to die off naturally so that it can be replaced with less
water. intensive landscaping. The alternative, using chemicals to remove the existing
vegetation, is less desirable because it contributes to water pollution. (However, property
owners who preferred to remove existing vegetation with chemicals would not be
prohibited from doing so,)
- 3 -
To participate in the program, a property owner would apply for a Water Wise
Landscaping Permit from the Development Services Department To obtain the Permit,
the owner would need to sign a separate Water Wise Landscaping Agreement
(Attachment A), The Agreement would require the owner to comply with all provisions
of the Proposed Ordinance and with the Water Wise Landscape Guidelines provided by
the Water Resources Institute, (The Guidelines are attached to the Agreement,
Attachment A) In addition, the Institute has agreed to provide Development Services
with yard signs that participants must display in their front yards to infotm Code
Enforcement of their participation in the program and prevent their being cited,
After the existing vegetation had been retired, the owner would have until the
following May 31 to complete the installation of drought-resistant landscaping.
Compliance would be verified by requiring the owner to file a Certificate of Completion
accompanied by adequate proof that the project had been installed as approved.
Ms. Longville states that the minimum time to retire a grass lawn in the summer
without using chemicals is three months. The only season during which drought-tolerant
plants can be installed successfully in the Inland Empire begins in December and ends in
January. Roots become established during the cool weather, with the plants maturing in
May. In view of these time factors, the Proposed Ordinance would impose the following
requirements:
. A property owner could obtain a Water Wise Landscaping Permit at any
time, but the Permit would be effective for a maximum of one year.
. The Permit would exempt the owner from compliance with the Code
sections disallowing dead or dry vegetation, as applied to the conversion area only. The
rest of the property would have to be maintained in compliance with all Code
requirements.
. Installation of the replacement landscaping would have to be completed by
the next May 31. On and after that date, the owner would have to demonstrate full
compliance with the Code, including the provisions prohibiting dry or dead vegetation,
Thus, an owner who had not completed the conversion to drought-tolerant vegetation by
that date would be subject to citation for any remaining dry or dead vegetation.
. An owner who obtained a Permit but later decided not to proceed with the
landscape conversion could withdraw from the program by paying a withdrawal fee of
one hundred dollars for each month the Petmit was in effect, prorated for partial months.
S. Recommendation
That the Proposed Ordinance be laid over for final adoption.

Water Wise Landscape Guidelines
For Water Wise Landscape ProVllm
I. A "Water Wise Landscape Program" is a landscape that uses drought tolerant, California
friendly landscaping in lieu of large turf areas, and that uses efficient irrigation.
2, Residents should prepare a design plan for the area to be converted from an existing
landscape before beginning the process of retiring the turf, amending the soil as necessary,
retrofitting the irrigation system (if applicable), grading and planting. Information about
removing turf and getting started with sample design templates, irrigation system retrofitting,
and the selection of watcr-cfficient plant materials is available from the following websites
and similar sites, and from published literature:
http://www.bewaterwise.comlGardensoftlindex.aspx
http://www.snWlLcomlhtmllland_digin....grass_removal.html
water Wise Landscape advice is also available at the Water Resources Institute at Cal State,
San Bernardino at: (909) 537-7687.
3. A Water Wise Landscape shall consist o(water-efficient, drought tolerant and native plant
material and may include ground covers, small plants, shrubs and appropriate trees. Buffer
areas and bioswales may be included and may be designed with rocks, cobble or decomposed
granite, landscaped shrubs or accents, or suitable ground cover,
4. All planted areas must be a minimum of one inch below adjacent hardscapes (sidewalks and
driveways) to eliminate runoff and overflow of irrigation water.
5. Avoid the use of mounded or sloped planting areas that would contribute to runoff of
irrigation water onto non-irrigated areas, walks, roadways or structures,
6, Any turf areas should be set back at least 24 inches from curbs, driveways, sidewalks or any
other area that may result in runoff of irrigation water onto streets.
7. Plants having similar water use should be grouped together so you can water
efficiently. These groupings are called "hydrozones."
8. Annual color plantings should be used only in areas of high visual impact close to where
people can appreciate them, Otherwise perennial p1antings should be the primary source of
color.
9. Landscaping must not obstruct or interfere with street signs, lights or road/walkway
visibility,
Maintenance
Landscapes shall be maintained to ensure water efficiency including rcplenishing mulch;
fertilizing; pruning; and weeding in all landscaped areas, Regular maintenance of irrigation
system (if applicable) should include checking, adjusting, cleaning and repairing irrigation
equipment; resetting the automatic controller, aerating and dethatching turf areas.

Chapter 2.7. Model Water Efficient Landscape Ordinance
~ 490. Purpose.
(a) The State Legislature has found:
(1) that the waters of the state are oflimited supply and are subject to ever increasing demands;
(2) that the continuation of California's economic prosperity is dependent on the availability of adequate
supplies of water for future uses;
(3) that it is the policy of the State to promote the conservation and efficient use of water and to prevent
the waste of this valuable resource;
(4) that landscapes are essential to the quality of life in California by providing areas for active and
passive recreation and as an enhancement to the environment by cleaning air and water, preventing
erosion, offering fire protection, and replacing ecosystems lost to development; and
(5) that landscape design, installation, maintenance and management can and should be water efficient;
and
(6) that Section 2 of Article X of the California Constitution specifies that the right to use water is
limited to the amount reasonably required for the beneficial use to be served and the right does not and
shall not extend to waste or unreasonable method of use.
(b) Consistent with these legislative findings, the purpose of this model ordinance is to:
(1) promote the values and benefits of landscapes while recognizing the need to invest water and other
resources as efficiently as possible;
(2) establish a structure for planning, designing, installing, maintaining and managing water efficient
landscapes in new construction and rehabilitated projects;
3) establish provisions for water management practices and water waste prevention for existing
landscapes;
(4) use water efficiently without waste by setting a Maximum Applied Water Allowance as an upper
limit for water use and reduce water use to the lowest practical amount;
(5) promote the benefits of consistent landscape ordinances with neighboring local and regional
agencies;
(6) encourage local agencies and water purveyors to use economic incentives that promote the efficient
use of water, such as implementing a tiered-rate structure; and
(7) encourage local agencies to designate the necessary authority that implements and enforces the
provisions of the Model Water Efficient Landscape Ordinance or its local landscape ordinance.

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
'rrigation 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 MAW A 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 MAW A, the annual reference
evapotranspiration value for Fresno is 51.1 inches as listed in the Reference Evapotranspiration Table in

MAWA = (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)]
MAW A = 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)

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 = 7 48 gallons)
:) In this next hypothetical example, the landscape project in Fresno, CA has the same ETo value of
J 1.1 inches and a tota11andscape 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.
MA WA = (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)]
MAW A = (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

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 MAW A.
ETWU = (ETo)(0.62l PF :~HA + SLA I
(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.

Compare ETWUwith 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 MAW A.
(2) Example ETWU calculation: total landscape area is 50,000 square feet, 2,000 square feet of which is
,Jlanted 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

SECTION B. WATER BUDGET CALCULATIONS
Section 81. Maximum Applied Water Allowance IMAWAI
The project's Maximum Applied Water Allowance shall be calculated using this equation:
MAWA = (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)]
where:
MAWA = Maximum Applied Water Allowance (gallons per year)
ETo = Reference Evapotranspiration from Appendix A (inches per year)
0.7 = ET Adjustment Factor (ETAF)
LA = Landscaped Area includes Special Landscape Area (square feet)
0.62 = Conversion factor (to gallons per square foot)
SLA = Portion of the landscape area identified as Special Landscape Area (square feet)
0.3 = the additional ET Adjustment Factor for Special Landscape Area (1.0 - 0.7 = 0.3)
Maximum Applied Water Allowance =
. gallons per year
