§ 492.4 Water Efficient Landscape Worksheet.
(a) A project applicant shall complete the Water Efficient Landscape Worksheet which contains two
sections (see sample worksheet in Appendix B):
(1) a hydrozone information table (see Appendix B, Section A) for the landscape project; and
(2) a water budget calculation (see Appendix B, Section B) for the landscape project. For the calculation
of the Maximum Applied Water Allowance and Estimated Total Water Use, a project applicant shall use
the ETo values from the Reference Evapotranspiration Table in Appendix A. For geographic areas not
covered in Appendix A, use data from other cities located nearby in the same reference
evapotranspiration zone, as found in the CIMIS Reference Evapotranspiration Zones Map, Department
of Water Resources, 1999.
(b) 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.
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 p IE A + SLAJ
Where: l
ETWU = Estimated Total Water Use per year (gallons)
ETo = Reference Evapotranspiration (inches)
PF = Plant Factor from WUCOLS (see Section 491)
HA = Hydrozone Area [high, medium, and low water use areas] (square feet)
SLA = Special Landscape Area (square feet)
9.62 = Conversion Factor
IE = Irrigation Efficiency (minimum 0.71)
,(I) 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.

§ 492.7 Irrigation Design Plan.
(a) For the efficient use of water, an irrigation system shall meet all the requirements listed in this
section and the manufacturers' recommendations. The irrigation system and its related components shall
be planned and designed to allow for proper installation, management, and maintenance. An irrigation
;design plan meeting the following design criteria shall be submitted as part of the Landscape
Documentation Package.
(1) System
(A) Dedicated landscape water meters are highly recommended on landscape areas smaller than 5,000
square feet to facilitate water management.
(B) Automatic irrigation controllers utilizing either, evapotranspiration or soil moisture sensor data shall
be required for irrigation scheduling in all irrigation systems.
(C) The irrigation system shall be designed to ensure that the dynamic pressure at each emission device
is within the manufacturer's recommended pressure range for optimal performance.
1. If the static pressure is above or below the required dynamic pressure of the irrigation system,
pressure -regulating devices such as inline pressure, regulators, booster pumps, or other devices shall be
installed to meet the required dynamic pressure of the irrigation system.
2. Static water pressure, dynamic or operating pressure. and flow reading of the water supply shall be
measured at the point of connection. These pressure and flow measurements shall be conducted at the
design stage. If the measurements are not available at the design stage, the measurements shall be
conducted at installation.
(D) 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, as
appropriate for local climatic conditions. Irrigation should be avoided during windy or freezing weather
or during rain.
(E) 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.
13
(F) Backflow prevention devices shall be required to protect the water supply from contamination by the
irrigation system. A project applicant shall refer to the applicable local agency code (i.e., public health)
'for additional backflow prevention requirements.
(G) High flow sensors that detect and report high flow conditions created by system damage or
malfunction are recommended.
(H) The irrigation system shall be designed to prevent runoff, low head drainage, overspray, or other
similar conditions where irrigation water flows onto non -targeted areas, such as adjacent property, non -
irrigated areas, hardscapes, roadways, or structures.
(I) Relevant information from the soil management plan, such as soil type and infiltration rate, shall be
utilized when designing irrigation systems.
Q) The design of the irrigation system shall conform to the hydrozones of the landscape design plan.
(K) The irrigation system must be designed and installed to meet, at a minimum, the irrigation efficiency
criteria as described in Section 492.4 regarding the Maximum Applied Water Allowance.
(L) It is highly recommended that the project applicant or local agency inquire with the local water
purveyor about peak water operating demands (on the water supply system) or water restrictions that
may impact the effectiveness of the irrigation system.
(M) In mulched planting areas, the use of low volume irrigation is required to maximize water
infiltration into the root zone.
(N) Sprinkler heads and other emission devices shall have matched precipitation rates, unless otherwise
directed by the manufacturer's recommendations.
(0) Head to head coverage is recommended. However, sprinkler spacing shall be designed to achieve
the highest possible distribution uniformity using the manufacturer's recommendations.
(P) Swing joints or other riser -protection components are required on all risers subject to damage that
are adjacent to high traffic areas.
(Q) Check valves or anti -drain valves are required for all irrigation systems.
,(R) Narrow or irregularly shaped areas, including turf, less than eight (8) feet in width in any direction
shall be irrigated with subsurface irrigation or low volume irrigation system.
(S) Overhead irrigation shall not be permitted within 24 inches of any non -permeable surface. Allowable
irrigation within the setback from non -permeable surfaces may include drip, drip line, or other low flow
non -spray technology. The setback area may be planted or implanted. The surfacing of the setback may
be mulch, gravel, or other porous material. These restrictions may be modified if.
1. the landscape area is adjacent to permeable surfacing and no runoff occurs; or
2. the adjacent non -permeable surfaces are designed and constructed to drain entirely to landscaping; or
3. the irrigation designer specifies an alternative design or technology, as part of the Landscape
Documentation Package and clearly demonstrates strict adherence to irrigation system design criteria in
Section 492.7 (a)(1)(H). Prevention of overspray and runoff must be confirmed during the irrigation
audit.
(T) 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 landscape designer specifies an
alternative design or technology, as part of the Landscape Documentation Package, and clearly
demonstrates no runoff or erosion will occur. Prevention of runoff and erosion must be confirmed during
the irrigation audit.
(2) Hydrozone
(A) Each valve shall irrigate a hydrozone with similar site, slope, sun exposure, soil conditions, and
plant materials with similar water use.
(B) Sprinkler heads and other emission devices shall be selected based on what is appropriate for the
plant type within that hydrozone.
(C) Where feasible, trees shall be placed on separate valves from shrubs, groundcovers, and turf.
(D) Individual hydrozones that mix plants of moderate and low water use, or moderate and high water
'use, may be allowed if.
14
1. plant factor calculation is based on the proportions of the respective plant water uses and their plant
factor; or
�. the plant factor of the higher water using plant is used for calculations.
(E) Individual hydrozones that mix high and low water use plants shall not be permitted.
(F) On the landscape design plan and irrigation design plan, hydrozone areas shall be designated by
number, letter, or other designation. On the irrigation design plan, designate the areas irrigated by each
valve, and assign a number to each valve. Use this valve number in the Hydrozone Information Table

Model Water Efficient Landscape Ordinance
California Code of Regulations
Title 23. Waters
Division 2. Department of Water Resources
Chapter 2.7. Model Water Efficient Landscape Ordinance
§ 490. Purpose.
(a) The State Legislature has found:
(1) that the waters of the state are of limited 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.

§ 492.4 Water Efficient Landscape Worksheet.
(a) A project applicant shall complete the Water Efficient Landscape Worksheet which contains two
sections (see sample worksheet in Appendix B):
(1) a hydrozone information table (see Appendix B, Section A) for the landscape project; and
(2) a water budget calculation (see Appendix B, Section B) for the landscape project. For the calculation
of the Maximum Applied Water Allowance and Estimated Total Water Use, a project applicant shall use
the ETo values from the Reference Evapotranspiration Table in Appendix A. For geographic areas not
covered in Appendix A, use data from other cities located nearby in the same reference
evapotranspiration zone, as found in the CIMIS Reference Evapotranspiration Zones Map, Department
of Water Resources, 1999.
(b) 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.
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)P x A + SLAIE
Where:
ETWU = Estimated Total Water Use per year (gallons)
ETo = Reference Evapotranspiration (inches)
PF = Plant Factor from WUCOLS (see Section 491)
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.

Eva,
I just confirmed with Larry. It is our opinion that the Code does not require publication of a summary in this
instance. Therefore, the Council may move forward with the second reading and adoption of the ordinance at the
coming week's meeting. This means that the dates may remain as they are.
Please let me know if you have questions.
Thanks,

I need some assistance on the first summary for the Ordinance Nelly needs to post tomorrow. Attached is what I
have started but not sure what should follow; could you please help?
Also, there was a mistake on the actual Ordinance. The second reading should be for November 2"d not October
26tn Should I change the dates and replace the pages (pages 2, 5 and 6)? What do you suggest?
Thank you.

COMMUNITY SERVICES & WATER DEPARTMENT
DATE: August 31, 2009/ (o ��4 L 0
TO; Honorable Mayor and City Council
FROM; Samuel Kevin Wilson, Director of Community Services and Water
RE Water Conservation Ordinance No.1161
The State of California has experienced below average rainfall for the past two years. The low rainfall
levels coupled with reductions in State Water, Project Water due to environmental restrictions have greatly
impacted the State's ability to meet surface water supply demands. In order to address the dwindling water
supply, Governor Arnold Schwarzenegger proclaimed a statewide droughtissuing Executive Order S-06-08 on
June 4, 2008. The Executive Order directs local water agencies and districts to support and facilitate water
conservations measures. Agencies and districts alike are encouraged to work collectively at the regional and
state level to take drastic and immediate action to. reduce water consumption. To meet this challenge, the
Metropolitan Water District (MWD) has developed a Model Conservation Ordinance (Model Ordinance) to
address the State's dwindling water supplies and to assist water purveyors with structuring a conservation
ordinance that will serve to reduce water wasting activities and at the same time free up precious water supplies
for human consumption.
The MWD has officially adopted a policy directing cities to have a Water Conservation Ordinance.
.Cities are not required by law to have a Model Ordinance in place; however, the Model Ordinance is a
prerequisite for future state and federal funding opportunities that could be of significant benefit to the City in
the future. In addition; surface water supplies in California have been drastically reduced due to recent Court
rulings that require the State Water Project distribution pumps. to be shutdown in the event environmental groups
have determined through quantitative analysis that Delta Smelt colonies have been adversely impacted' by water
intake pumps. The recent Court ruling along with persistent drought conditions in the state make the, availability
of surface water supplies in the future uncertain. The City may have to rely solely on its groundwater supplies to
meet future water demand requirements making conservation of paramount importance.,
The Water Department (Department) performed a comprehensive review of the MWD Model Ordinance
and found that the City's existing Conservation Ordinance No. 995 met most of the requirements reflected in the
above -mentioned Model Ordinance. The Department has incorporated the amendments and additions to
Ordinance No. ' 995. It should be noted that the Ordinance will require, mandatory restrictions that must be.
adhered to even when no water supply shortage has been officially declared. These restrictions include limits on
watering hours, limits on watering duration, no excessive water flow or runoff; no washing down hard or paved
surfaces; an obligation to fix leaks, breaks or malfunctions; water required for water fountains and decorative
water features must function on a recirculation system; limits on washing vehicles; drinking water shall only be
served at restaurants upon request; no installation of single pass cooling systems; and the installation of non -
circulating water systems is prohibited in new commercial conveyor car wash systems and new commercial
laundry systems.
If water shortage conditions exist requiring:a curtailment in water use the City Council may impose a
Phase I, I1, or III water shortage declaration which will impose further conservation measures. Phase I
restrictions place limits on watering days and specify times in which customers,, have to, repair leaks. No
mandatory water usage limits are required under a Phase I Water Supply Shortage. Phase II restrictions place
limitations on watering days, leak repairs, filling of ornamental lakes or ponds, washing vehicles, filling
swimming pools, and irrigation of commercial nurseries. In addition, no customers shall make, cause, use of
permit the use of City water for any purpose in excess of eighty-five percent (85%) of the amount used in the
same corresponding monthly billing period two (2) years preceding the City Council declaring a Phase I Water
Supply Shortage. In the case of a newly established business, no restriction shall be required until such time that
the business has been established for one (1) year, at which time the preceding year's corresponding monthly
billing period preceding the City Council declaring -a Phase I Water Supply Shortage shall be used to determine
the businesses monthly water consumption: Phase III restrictions include those identified in Phase II with more
stringent requirements reflected in each of the above -mentioned categories. In terms of water usage restrictions,
no customers shall make, cause, use of permit the use of City water for any purpose in excess of seventy-five
percent (75% o) of the amount used in the same corresponding monthly. billing period two (2) years preceding the
City Council declaring a Phase I Water Supply Shortage. In the case of a newly established business, no
restriction shall be required until such time that the business has been established for one (1) year, at which time
the preceding year's corresponding monthly billing period preceding the City; Council declaring a Phase I Water
Supply Shortage shall be used to determine the businesses monthly water consumption. The penalties for failure
to comply with any provisions of the Ordinance in terms of consumption are as follows:
1. For each violation by any customer of the water use curtailment provision of Section No. 25.104, Pba"se II; a
surcharge shall be imposed in an amount equal to' fifty percent(50%) of 'the portions of the waterbill that
exceeds the respective percentages set in the said section:
2. For each violation by any customer of the water use curtailment provision of section No. 25.105 Phase.111, a
surcharge shall be'imposed in an amount equal to one hundred percent (100%) of the portions of the water bill
that exceeds the respective percentages set in the said section.
Violation by any customer of any of any other water use prohibitions of the Ordinance shall be penalized as
follows:
1. First violation: A written notice of the first violation shall be issued to the customer.
2. Second Violation: For a second violation the City shall impose a surcharge in an amount equal to ten`percent
(10%) of the customer's water bill.
3. Third and subsequent violations For a third and each subsequent violation, the City may impose an additional
surcharge of ten percent (10%) for each violation and the City may install a flow restricting device on the
service of the customer at the premises at which the violation occurred for a period determined by the Director
of Community Services.
Additionally, the Department of Water Resources (DWR),'based on provisions of Assembly Bill 1881,
is requiring' cities to adopt a Model Efficient Landscape Ordinance' (Model Ordinance), or its equivalent; by
January 1, 2010. The Model Ordinance, like the MWD Model Ordinance,` gives the cities the option to adopt a
ordinance developed by another city that has received official compliance certification from the DWR.'If a city
opts not to take any action with respect to developing a Model Ordinance, the DWR Model Ordinance will be
adopted by "statute on January 1, 2010. Staff is recommending that the Model Ordinance be adopted by
reference.
Staff has recommended that the City's Water Conservation Ordinance No. 995, Sections: ,25.100,
25.101, 25.102, 25.103, 25.104, 25.105, 25.106, and 25.107 be amended as illustrated on the attached report in
order to meet the requirements of the MWD Model Ordinance. Moreover, included in the above -mentioned
report is a recommendation that the City incorporate Section 25.112, adopting by reference, the DWR State
Model Landscaping Ordinance that shall become effective January 1, 2010.
Finally, it is recommended that the City Council find that the Adoption of the Ordinance is exempt from
the California Environmental Quality Act per sections 15061 (b) (3) and 15308 due to the fact that it will not
have a significant effect on the environment as the Ordinance will have a limiting effect rather that authorize the
use of water and constitutes an action by the City to assure the maintenance enhancement and protection of the
environment through the conservation of water resources.
It is then my recommendation that the City Council approve the amendments to the City's Water
Conservation Ordinance No. 995 and the addition of Section 25.112.

COMMUNITY SERVICES & WATER DEPARTMENT
OFFICE MEMORANDUM
TO: Donal O'Callaghan, City Administrator Cg
FROM: Samuel Kevin Wilson, Director of Community Services and Water -
DATE: August 31, 2009
SUBJECT: Water Conservation Ordinance No.1161
The State of California has experienced below average rainfall for the past two years. The lowrainfall
levels coupled with reductions in State Water Project Water due to environmental restrictionshave greatly
impacted the State's ability to meet surface water supply demands. In order to address the dwindling water
supply, Governor Arnold Schwarzenegger proclaimed a statewide drought issuing Executive Order S-06-08 on
June 4, 2008. The Executive Order directs local water agencies and districts to support and facilitate` water
conservations measures. Agencies and districts alike are encouraged to work collectively at the regional and
state level to take drastic and immediate action to reduce water consumption. To meet this challenge, the
Metropolitan Water District (MWD) has developed a Model Conservation Ordinance (Model Ordinance) to
address the State's dwindling water supplies and to assist water purveyors with structuring a' conservation
ordinance that will serve to reduce water wasting activities and at the same time free up precious water supplies
for human consumption.
The MWD has officially adopted a policy directing cities to have a Water Conservation Ordinance.
Cities are not required by law to have a Model Ordinance in place; however, the Model Ordinance` is a
prerequisite for future state and federal funding opportunities that could be of significant benefit to the City in
the future. In addition, surface water supplies in California have been drastically reduced due to recent Court
rulings that require the State Water Project distribution pumps to be shutdown in the event environmental
groups have determined through quantitative analysis that Delta Smelt colonies have been adversely impacted
by water intake pumps. The recent Court ruling along with persistent drought conditions in the state make the
availability of surface water supplies in the future uncertain. The City may have to rely solely on its
groundwater supplies to meet future water demand requirements making conservation of paramount
importance.
The Water Department (Department) performed a comprehensive review of the MWD Model
Ordinance and found that the City's existing Conservation Ordinance No. 995 met most of the requirements
reflected in the above -mentioned Model Ordinance. The Department has incorporated the amendments and
additions to Ordinance No. 995, per the attached staff report. Staff is recommending that permanent•mandatory
restrictions be established that must be adhered to even when no water supply shortage has been officially
S E P 0.8 2009
on No. 1161 City Adminisfa r.doc
declared. In addition, if the City Council were to determine that a Water Supply Shortage Phases 1, II, and III
was necessary, additional restrictions and the penalties associated with each Phase would be implemented.
The Department of Water Resources (DWR), based on provisions of Assembly Bill 1881, is requiring
cities to adopt a Model Efficient Landscape Ordinance (Model Ordinance), or its equivalent, by January 1,
2010. The Model Ordinance, like the MWD Model Ordinance, gives the cities the option to adopt an ordinance
developed by another city that has received official compliance certification from the DWR. If a city opts not to
take any action with respect to developing a Model Ordinance, the DWR Model Ordinance will be adopted by
statute on January 1, 2010 Staff is recommending that the Model Ordinance be adopted by reference.
Staff has recommended that,tYie City's Water Conservation Ordinance No. 995, Sections: 25.100,
25.101, 25.102, 25.103, 25.104, 25.105, 25.106, and 25.107 be amended as illustrated on the attached report in
order to meet the requirements of the MWD Model Ordinance. Moreover, included in the above -mentioned
report is a recommendation that the City incorporate Section 25.112, adopting by reference, the DWR State
Model Landscaping Ordinance that shall become effective January 1, 2010. In, addition, it is recommended that
the City Council find that the Adoption of the Ordinance is exempt from the California Environmental Quality
Act due to the fact that it will not have a significant effect on the environment as the Ordinance will have a
limiting effect rather than authorize the use of water.
It is then my recommendation that the first reading to consider adoption of the amendments to Chapter
25 Article VI Water. Conservation of the City Code be held at the October 5, 2009 City Council meeting in
order to allow sufficient time to publish an overview of the proposed amendments in the Vernon Gazette.

DATE: October 6, 2009
SUBJECT: WATER CONSERVATION ORDINANCE NO. 1161
The Water Department has previously submitted Ordinance No. 1161 regarding amending the City's
water conservation requirements for consideration by City Council. In consultation with our consultant
preparing the City's Urban Water Management Plan he suggested that language be added to the ordinance
establishing when each phase of the water supply shortage requirements should be implemented.
One sentence was added to Sections 25.103, 25.104, and 25.105 to establish this threshold for each
phase. The City Attorney's office has reviewed and approved the added language. The Staff Report previously
submitted continues to be valid.
Please place Ordinance No. 1161 on the October 19, 2009 agenda for City Council consideration.

I have reviewed your proposed changes to the Water Conservation Ordinance. I have also reviewed the State
Water Code with regard to Urban Water Management Plans (Water Code Section 10610 et seq.) and did not see
any recent modifications detailing the consultant's concerns. Without reviewing the additional requirements
mentioned by the consultant I cannot make a legal determination as to these additions. However, if you have
something in writing you would like for me to review, or if you would like me to speak with the consultant, I
am more than happy to do so.
Also, I re -reviewed the Ordinance for any necessary changes in regards to the additional information you
provided by telephone in regards to the fact that the City only provides water service for certain areas in the
City, with other entities providing water service for the remaining areas. The Ordinance captures this concern
with the language in Section 25.100 where it states, "[t]he provisions of this article apply to any person in the
use of any potable water provided by the City." Additionally, various sections in the Ordinance specify
"customer of the City of Vernon" for clarity purposes.
Please contact me if you have any questions regarding these comments.
Kind regards,

Hi Kevin,
By way of this email, I'm forwarding it to Chris Diaz, who preformed the original review. He can review the modifications
you made to the ordinance.
FYI - Oct. 12 is Columbus Day, and I'm told there is no City Council meeting that day. The next meeting date after that is
October 19th. Staff reports are due October 14th, and we should target for that date.

Subject: Water Conservation ordinance
I have requested that the water conservation ordinance be removed from the October 5, 2009 agenda and
hopefully we can place it on our October 12, 2009 agenda. We are currently working with a consultant to
update our urban water management plan. This plan is mandated by the State of California and has to be
updated every 5 years. Our consultant has just advised us that the State of California is now mandating
thresholds be set when conservation measures must be taken. The way our current ordinance is written leaves
the determination of a water shortage up to the City Councils discretion. While we would like to leave some
discretion for the council we must establish a threshold when the water conservation requirements will be
mandatory. I have amended the water conservation ordinance to establish these thresholds. Can you have the
revised ordinance language reviewed.
Thanks for your assistance.
