The Plan addresses the City's water `system and includes a description ofthe water supply
sources, magnitudes of historical and projected wateruse; and a' comparison of water supply to
water demands during normal - single =dry, and mu_ ltiple =dry years. Water management tools, such

adopted General Plan 2025, in both the water supply' and wastewater treatment /reuse systems.
The 2010' Urban Water Management Plan:updates the projected.demand based on the adopted
General Plan 2025 land use plan, but extends the'expected General Plan horizon for purposes of
population, and, water supply and demand to 2035 because of reductions in anticipated growth
and water demand that have resulted and are still
� pd execte from the'economic downturn. The
Plan identifies contractual and' regulatory constraints to the City's ,existing water supplies,
suggests and evaluates alternatives, and prepares the Plan in accordance with City policy and
State requirements.

SCWA has prepared its Urban Water Management Plan for Wholesale water providers and was
heard by'ifs Board of Directors for public hearin g on the 24 -of May. We have been working
with'''SCWA toncoordinate our. efforts and to participate their work effort to ensure consistency
between our Urban. Water Management Plan and their document.
The City had th - e opportunityto join the other water, contractors in the Analysis
project which supportsr:the "Agency's wholesaler's 2010 UWMPI. City Management and Staff
chose not to jom'because the'Department felt that the distribution analysis that was developed
under the 2025 General Plan was more precise and, more accurately representative of our current

Attachment 2
1. Comment: UWMP should more clearly define the term "emergency use regarding use of
groundwater to meet,potable demand.
The City's adopted policy regarding the use of,ground water is currently ' °defined in the adopted
2025 General Plan (GP), Water Resources Element in the Ground Water Section.' It states that
the City intends to use ground° water "for' "standby rand emergency conditions" it further defines
these conditions on page 8 -6 of the GP. The requirements of the UWMP rely heavily on the
adopted policies of the 2025' GP;. The` requested additio, ,of language to further define .
emergency would be inconsistent with that document, but may be addressed in future GP
amendment or updating work•efforts. Please note that the plan,, using those GP policies does
not utilize ground water as a fixed component of the local supply offsets (recycled water,
conservation, and the like) for the full planning period.
2. Comment: lack of agricultural water customers within the City.
The City does not currently have any'i "dentified,Ag customers on the potable water system.
Petaluma Bounty Garden, currently located on Shasta Ave does have a Commercial Meter and
check valve assembly, The site is currently utilizing a'well on! site forregular production and the
check valve assembly is valved off. The only parcels: in the Urban Growth Boundary that are
identified for Ag use in the 2025 GP are the pumpkin patch the lower portion of the KOA and
the Hummel property on the northeast side of Highway (across from the pumpkin patch).
These parcels are not currently being served, by the City's system nor will they be in the
foreseeable future.
3. Comment: Source and accuracy of population numbers:
The Population for the UWMP is a combination of therDepartment of Finance population,
projected land use populations and quantified population (USCG Base). When the Demand
analysis was being done the 2010 Census data was not available and DWR guidelines
recommend' using DOFor ABAG. The DOF numbers were preferred as they provided annual
population estimates that were used to calculate the annual'baseline gpcd for the 20x2020
compliance requirements. The 2010` Census population - estimate for City of Petaluma is 57,941.
The UWMP estimated 2010 population using the 20x2020 analysis methodology to remain
consistent throughout the.analysis. The UWMP estimated City of Population at 57,922, which is
less then a 0.1 percent difference compared to the 2010 Census estimate.
4. Comment: Public'comment by Sonoma County Waste Management Agency requesting
identification of site and recycled water use within the UWMP.
Sonoma County Waste Management- Agency's request to be added to the UWMP is not
consistent with the requirements for the Plan. Although the project site is currently served by
recycled wat'er'for agricultural uses, the proposed use would be an intensification. This
intensification of water use may not be consistent with current City policy regarding the
prohibition of the extension of Water and Sewer Utilities outside the Urban Growth Boundary.
In addition, the project has no projected potable water demand on the City's water system;
therefore there is no nexus for their project to be incorporated into the demand calculations for
the UWMP. The SCWMA request is for secondary recycled water from the City. Similar to the
current Ag customers SCWMA Would not be counted as potable water offset and not covered in
the Plan. Following,adoption of the Plan, the Department will continue discussions with
SCWMA with the goal of developing a revenue- positive solution.
5. Comment: Consistency in tables;for 5 -year incremental data.
Tables 3 -7 and 3 -8 are provided by the City of Santa Rosa and present the Regional Compliance
group baseline and target,calcul'ations. The weighted gpcd values for 2005 and 2010 are not a
part of the baseline and target calcuiation process.. Historic, weighted gpcd values could be

appended to the UWMP if.the Re Tonal Com lian
City of Petaluma historic gpcd values from 1995 -2010 are shown in Table 3 -2.
We added a footnote to table 3 -14 that2005 and 2010 net,demand values are listed in Table 3-
1.
6. Comment: Lost Water calculations
Text has been modified to more accurately reflect'the department's operational processes. (pg.
i3t3
"The Operations and Maintenance staff of WR &C conduct the efforts for this DMM. Staff
monitors production and sales records:on a monthly basis to identify unaccounted for water.
Annual reports are also developed with unaccounted for water compared to past years to trend
and identify any potential issues. WR &C'.has monitoring unaccounted for water for at least
the last 20 years. The unaccounted for water value -in 2010 was•approximately 9 percent.
WR &C operations and conservationstaff maintain the annual water audit program per the
AWWA Water Audit Model. WR &C adjusts its leak detection and repair activities based on real -
time leak frequency, audit results, and field observations. Currently, staff repairs leaks as
identified and monitorIcir'specific leak'patterns by locatio0 "material, pressure, and other
parameters. WR &C also monitors and enforces: registration of contractors accessing water from
hydrants,:requiring a meter be used for payment calculations.
7. Comment: • Table 2 -1. Population projections should show line items for in -city and out of city
components.
Footnote added for °each portion of the 2010 estimate and future projections. (pg. 5)
8. Comment: Add a discussion of grey systems as a potential future water supply.
A discussion of grey water systems as potential future water supply has been added to Section
4.4� (see attached).
9. Comment: Define UAW and System Loss Table 3 -1.
Definitions,and descriptions have bee n amended to text. The difference between the system'
,
loss at 4+ percent and 'the modeled 8 percent UAW is that there are,account corrections (non
revenue water) after the initial recording event resulting in a total lost water percentage of 8
percent.
10. Comment: GP is 2008, not 2006 (pg 13).
Correction made to reflect title as.General Plan 2025, adopted in'2008.
11. Comment: `income" is misspelled (pg 13).
Correction made.
12. Comment: Table 44 and 4 -2 Iist:2010 surface and ground water total as 8,000 AF. Table 3 -13
lists total 2010 demand as 7,963 AF., which is inconsistent.
2010 UAW was corrected; total 2010 net demand is 7,998 AF which matches total supply of
8,000 AF (within 0.1 percent difference). Table 3 -1, 3 -12, and 3 -13 are updated.
13. Comment: Should have a reference for the statement that the new South Transmission System
is no longer needed (pg 28).
The Temporary Impairment cause and current status have been clarified. (pg 28). .
14. Comment: Request.clarification that SCWA did not provide reliability analysis in time for
development of current UWMP, and that plan uses 2005 analysis.
The.-SCWA reliabilityanalysis was not available when the Public Hearing Draft UWMP was
developed. Since that time, SCWA has provided a draft,of its supply reliability analysis. The
UWMP has been updated to reflect the findings frbeh the SCWA draft supply reliability analysis.
See pages 19, 27, and 28.

City'of Petaluma 2010 Urban Water;Management Plan

1 Plan Prep , a`
1rat10B1
The Urban Water Management Act (Act) became part of the California Water Code with
the passage of Assembly Bill 797 during the 1983 -1984 regular session of the California
Legislature. The California Water Code requires every urban water supplier °providing
water for municipal purposes either directly or indirectly to more than 3,000 or', ,
supplying more than 3,000 acre-feet of water annually to adopt and submit an Urban
Water Management Plan (UWMP) every five years to the California Department of
Water Resources (DWR). The "specific planning requirements are in the California Water
Code Division 6, Part 2.6 Urban Water Management Planning.
L I Introduction
This UWMP presents the City's water supply and planning programs per the UWMP
requirements. The core requirements for the UWMP include:
• A description of the water service area.
• A description of the existing and planned supply sources. '
• Estimates of past, present, and projected water use.
• A description of water conservation Demand Management Measures
(DMMs) already in place and planned, and other conservation measures.
• A description of the Water Shortage Contingency Plan.
• Recycled water opportunities.
The Delta Legislation passed in late 2009 resulted in a sweeping changeI for water
management within the State. Although the majority of the legislation addresses new
governance structures aimed at improving the health and management of the Delta, some
elements also addres§Aemand management by water agencies throughout the State. In
particular, SBX7 -7 Water Conservation, requires the state to achieve a20 percent reduction
in urban per capita water use by December 31, 2020, known as 20x2020: 20x2020
requirements are now incorporated into the 2010 UWMP requirements. In summary, the
UWMP must include the baseline demand analysis, water use target analysis. use for'2015
and 2020, and describe the programs to achieve the target demand "reds ctions,in the UWMP.

passage of SBX7 -7, DWR was tasked with developing the 20x2020 methodologies and
guidelines to include in' the 2010 UWMR The legislation also provided an extra six
months for agencies to complete the UWMP to incorporate all the new requirements.
Therefore, the 2010 UWMP must be approved by an agency by June 30, 2011, and
submitted to the DWR by August 1, 2011.

1.2 Coordination
2010 Urban Water Management Plan
The City is one of the retailers that purchase water from the Sonoma County Water
Agency (SCWA). The City routinely coordinates water resource planning efforts with
the other retailers and SCWA. The UWMP requires specific coordination efforts as .well.
The City must send a notice to all county and city governments within its service area of
its intent to develop and adopt a 2010 UWMP. This notice must be sent at least 60 days
prior to the public hearing to discuss the UWMP. A notice was sent to Sonoma County
informing them of the City's UWMP update as presented in Appendix A.
A public review process was included in the UWMP development. The City held a.
public review of the UWMP to discuss the plan and receive comments from the public.
The meeting was conducted at the May 16, 2011 Council Meeting. Public notice of the
meeting was provided two week prior to the hearing, as included in Appendix B.
The UWMP was approved at the June 6, 2011 Council meeting. The adoption resolution
is provided in Appendix C. Within 60 days of submittal to the DWR, the City will
submit a copy of the UWMP to Sonoma County. Within 30 days of submittal to the
DWR, the City will also submit a copy of the UWMP to California State Library, and
make a copy of the UWMP available for public viewing at the City's Utility department
office during normal business hours located at 202 North McDowell Boulevard,
Petaluma, CA 94954.
The new SBx7 -7 requirements for 20 percent demand reduction by 2020 allows for an
agency to identify an individual target goal and a regional target goal. The City includes
both goals in this UWMP. The City coordinated with the other SCWA retailers to
develop the regional alliance and set those goals. Both sets of goals and demand
projections are discussed in Section 3.
Table 1 -1 summarizes the coordination for Petaluma's 2010 UWMP development
process.
1.3 Implementation
The 2005 UWMP identified the City's plans for supply and demand management
id programs. The City planned to implement potable offset recycled water projects by
expanding the tertiary recycled water system. However, due to the economic! recession.
and a reduction in water demands, the recycled program implementation has been
delayed. The current status and implementation plan is further discussed. in Section 4.
The Water Resources and Conservation Department (WR &C) continues to evaluate its
supply options and will implement programs as necessary to effectively meet demand.
The 2005 UWMP also described the Water Utility's extensive demand management
program. In 2008, WR &C updated its conservation program to include even more
programs and potential water savings. The Water Utility's current conservation program
is in full implementation and has contributed to a portion of the demand reductions since
2005. The full program is discussed in Section 5.

City of Petaluma 2010 Urban Water Management Plan
2 System Description
WR &C serves water customers both within the City of Petaluma city boundary and
outside that boundary. This section describes the Water Utility's service area,
population, climate, and other elements.
2.1 Service Area Description
WR &C serves the majority of water to customers within the city boundary. Water is also
served to customers outside the boundary for a variety of reasons. Some outside
boundary customers were obtained when the previous private water company was
replaced in 1959 with a municipal water utility service, some customer's wells failed,
some customers were obtained from SCWA, as well as other specific reasons. WR &C's
largest customer outside of the boundary is the United States Coast Guard training station
located eight miles west of town. The water service area is shown in Figure 2 -1. WR &C
also provides recycled water for agricultural irrigation customers outside the City
boundary. These customers are all located to the southeast, near the City's water .
recycling facility.
The service area climate reflects its close proximity to the Pacific Ocean. The area is
subject to marine layer -type conditions throughout the year. The average summer time
temperature is 60 degrees F, and the average winter temperature is 45 degrees F. The
climate exhibits two distinct annual seasons, wet and dry. Most rainfall occurs in the
winter months, with almost no rain in the summer months. The total average annual
rainfall is 25 inches. The annual average evapotranspiration rate is approximately 44
inches.
2.2 Population
WR &C's service population is divided into two elements: customers within the City
limits, and those outside of the City limit. The water. utility serves smaller single farYily .
units outside the City boundary. The exception to this is that WR &C also serves the
Coast Guard training facility. Historic population data within the City limit is tracked` by
the California Department of Finance (DOF). Annual population and average persons
per household values are provided by the DOE The DOF also provides a persons,
dwelling unit value. The persons per dwelling unit value is used to estimate; the
population of residential connections outside the City's boundary. The 'Coast Guard
station provided a current population of 1,350.
Future population within the City boundary is projected in the City's General Plan 2025.
Population projections for customers outside the City boundary are developed with two
methods. The residential customer accounts use the persons per dwelling unit value from
the DOE The Coast Guard planning documents project population to expand to 1,935.
The City's General Plan projected land use and population out to 2025. Due to the
current economic conditions, the UWMP shifts the endpoint of the General Plan's
population projections out to 2035. Table 2 -1 lists the service area population projected
out to 2035.

household values are provided by the DOF. The Utility maintains and reports an annual
number. of "residentiaL;connections. The population value is divided by the residential
connections. This provides an estimate of persons per residential connection within City
limits. This value is `slightly higher than the DOF capita per,connection value because the
multi- family connections maintained by the Utility often serve multiple households.
However the DOF persons per, residential connection method was used to estimate' the
population of customers outside the City limits'based on the assumption that most of
these accounts are single= family connections. The one exception to this approach is the
United States.Coast Guard facility which provided population values directly to the
Utility. Thus,, total served by WR &C is the sum of the DOF population for
inside theI City limits and the estimated population for the customers outside the City

3.2.2 Regional Group. 2020 Alliance
The DWR UWMP Guidelines allow for 20x2020 compliance to be'met by a group of
water agencies known as a regional alliance. If the regional alliance meets its 2015 and
2020 target; all'members are considered incompliance. However.if the regional goals
are riot met, an agency can still be in compliance -by meeting their own individual goals.
The City, along with the other SCWA retailers, formed a regional - alliance as listed in.
Table 3 -6. The regional.alliance letter'agreement is included in Appendix D. The group
has selected Target Option - 1, 20 percent of baseline by 2020. The baseline calculation _is.
a° weighted average of each.'member's own 2015 and 2020 goals as shown in Table 3 -7. '
The development of each member's individual goal is presented in each respective
individual UWMP. The projected 2015 and 2020 gpcd values' are' presented in Table 3 -8. .

pated slowdown from the recession, this analysis shifted the General Plan end
conditions from 2025 4o 2035.
The ,General Plan projects growth using land use categories that differ from the customer
account categories defined in the DViWR 2010 UWMP Guidelines. Water demands
projected from the land' use- categories are grouped into the UWMP customer account
categories to provide; the required UWMP information. This sorting of the known data
sets strengthens the water demand projections obtained from the land use projections.
3.3.1 Customer Account Projections
Table 3 -9 lists the „past and projected potable water customer accounts. The Utility also
provides secondary recycled water agriculture customers. These customers are not
potable water customers and are not included in Table 3 -9. The agricultural customers
and secondary recycled system demands are discussed in Section 4.

Ih I' IN Y,i cate o also includes loss from leaks and meter inaccuracies. E ti (including all o sse
revenue water), are estimated at approximately eight percent of total sectoral water
r
demand based on historical data. System Losses for 2005 and 2010 are actual based on
meter records.
New legislation requires an agency to project water demands for low- income housing
needs. The General Plan 2025, incorporates the 2009 -2014 Housing Element. The
Housing element identified the City's portion of'the'regional housing need for very low
t o husehold housing needs. The 2009 housing needs are identified as 364
, units for very tOW o income households and 319 units„ for low - income households. These
new housing needs are assumed to continue through to. 2035„ This projection will be
updated when the City' updates the Housing Element after 2014. Table 3 -11 lists the
projected water demands for low- income housing units.
WR &C currently; operates a secondary treatment level recycled water system that
supplies irrigation water to agriculture and two golf courses. The Utility has developed a

phased approach for a new tertiary recycled water system that will serve mostly parks and
scl ools,'resulting in significant potable water offset. The f rsi phase is already complete
with construction of the Water Recycling Facility that can provide tertiary treated water.
The next phase is scheduled to commence in the 2011 capital improvement program.
The extent of tertiary distribution system implementation will depend on many factors
u., such as cost, wastewater discharge requirements, economic conditions, and others.
Therefore, full program implementation is not yet scheduled. The projected recycled
water volumes in Table 3 -12 represent the potable offset volume from the second phase
of the tertiary system, and assumes implementation by 2015. Recycled water plans are
further discussed in Section 4.
Although there are no other uses projected at this time, WR &C continues to evaluate its
future water resource needs and may develop plans for additional water uses as
necessary
Table 3 -12. Additional Water Uses and Losses (DWR Table 10)
Note: Recycled water use listed is only the potable ottset portion of the planned recycled use. The tma►
implementation schedule�is not yet approved. Table value assumed first phase implemented by 2015.
33.5 `Total Water Demand's
Total potable water demands are summarized in Table 3 -13. The total gross water
- , demands,, are, greater than the Utility's 2015 and 2020 gpcd targets. The Utility intends to
implement a combination of demand management efforts to reduce the gross demand to
+ meet,the'gpcdJargets.' Specifically, WR &C will continue 'implementation °ofits extensive
conservation program as described in Section 5. WR &C will continue to evaluate its
water rate schedule and update the rates as required. As discussed in Section 4, the
Utility. has planned an extensive recycled water system to be used for potable water offset
as: part of -the current General Plan. The system is divided into phases; with specific
phases implemented in the future to help meet the gpcd targets as well as address its
wastewater disposal requirements. The expected total demand reductions from the
Utility's programs are summarized in Table 3 -13, with the net demand and gpcd versus
targets presented. As shown, the WR &C projects it will meet its gpcd targets in 2015 and
2020.

In addi °tion, other issues impact the management of the Russian River system. SCWA is
working to improve its" , pply reliability through multiple efforts. The following
describes each issue and current status.
4.1.1 Water Supply Projects
SCWA developed' the Water Supplyand Transmission System. Project (WSTSP) in 1998
to increase diversions from the Russian River and. increase the transmission system
capacity. The WSTSP`was expected to increase SCWA Russian River diversions to
101,000 ac -ft/yr and increase the Agency's water transmission system average -day peak
month delivery capacity from 92 to 149 MGD.
T.he.Agency's Board of Directors, certified the WSTSP EIR in 1998. In 1'999 a lawsuit

supply impacts''and include:
Reducing summertime flows in the Russian River and Dry Creek
Enhancing six miles of habitat,in Dry Creek,
Creating a freshwater lagoon in the estuary during summer months
Monitorirg both habitat -and fish in Dry Creek, the estuary, and Russian River
Eliminating impediments fish spawning or improving habitat in several"
streams. .
IF The p B0 implementation of that reducing the minimum instream flow requirements will assist
r1 of other RPAs. SCWA filed a petition in Sep " "tember 2009 to the
SWRCB'requesting permanent changes to Decision '1,6 10 minimum flow requirements in
line with the B'iol'ogkalOpinion. SWRCB will act on the petition upon completion of the
EIR for Fish Habitat.Flows,and'WaterRights Project as described,.below. Until that time,
SCWA must request temporary changes to:the Decisions 161,0 minimum flows annually
per the BO recommendations. SCWA received its first temporary flow reduction petition
under the BO recommendations for 2010:
SCWA developed the Fish Habitat Flows and Water °Rights'Projecf to address the BO
RPAs and improve supply reliability., The project includes updating the Decision 1610
requirements
fl ow ' p er zthe BO, modifying reservoir release schedules and

With SCW, A s,:diversions currently limited to 75,000 AFY, SCWA has overcommitted
the available supply through the 2006 Restructured Agreement. The Restructured
Agreement lists a total of 77,445 AFY to the Water Contractors under Section 3.1
Delivery Entitlements'o.'f Water Contractors. The Restructured Agreement states SCWA
is not obligated to provide the City of Petaluma more ,than 13,400 acre -feet per year and
21.8 mgd average daily'` rateI during, any month. Until modified through an updated
contractor other means, the City assumes its reliable supply has.. not changed from the

Table 4 -4 lists the projected wastewater collected and the volume of recycled water
produced. The volume of'influent treated to recycled water standards is assumed equal to
potential demand listed in Table 4 -7. Up until 2009 when the new WRF went online, a
portion of the influent flow during wet weather events was bypassed around the influent
structure of the previous wastewater treatment plant located at Hopper street and sent to
the oxidation ponds for treatment. This results in some years having an effluent volume
higher than influent volume. olume. Table 4 -5 lists the past and projected volume of wastewater

4.4 Other Supply Opportunities
Currently there are no programs or projects for water transfers or exchanges of water to,
.
create additional supply for Petaluma. Until the WS.T.SP is constructed there may be
opportunities to wheel water through,,Petaluma's infrastructure but no programs have
been identified. WR &C continues to monitor future potential issues and will identify
additional; opportunities that may benefit Petaluma and the region's water needs.
One such potential opportunity is the, use of grey water. Water from rain runoff and even
washing machines could be captured,:and stored for use by the individual, homeowners.
Grey water system consideration for public supply purposes in California is still a,
developing field. The total potential supply for grey water systems depends on
precipitation timing, maximum; storage availability indoor water use, and other factors.
Grey water systems are currently permitted in Petaluma. WR &C will continue to
monitor;grey water system results from other communities to determine additional
applicability and opportunities for Petaluma.

create additional supply for Petaluma. Until the WS.T.SP is constructed there may be
opportunities to wheel water through,,Petaluma's infrastructure but no programs have
been identified. WR &C continues to monitor future potential issues and will identify
additional; opportunities that may benefit Petaluma and the region's water needs.
One such potential opportunity is the, use of grey water. Water from rain runoff and even
washing machines could be captured,:and stored for use by the individual, homeowners.
Grey water system consideration for public supply purposes in California is still a,
developing field. The total potential supply for grey water systems depends on
precipitation timing, maximum; storage availability indoor water use, and other factors.
Grey water systems are currently permitted in Petaluma. WR &C will continue to
monitor;grey water system results from other communities to determine additional
applicability and opportunities for Petaluma.

SCWA s supply is subjectto reductions to Dec ision 1610 based on Lake S "'' onoma „�
volume. Lake Sonoma has a total volume of 381,000 AF and a supply pool'of up• to
212,000 AF. When the total volume is less than 10,0,000 AF, the SCWA diversion is
subject to up to 30 percent reduction during `discrete time periods through the year. `Using „
the water type years as listed in Table 412, the _ SCWA supply has never been subject to
this reduction. With up to.thr 'ee.years of supply stored "in Lake Sonoma, the system is
relatively resistant to impacts from one to ;four years, of dry hydrology.. SCWA provided
a draft of'its UWMP water supply reliability. SCWA assumes that the supply during
portions of the year will be restricted by D1610 in a single -year dry-year event, but not a
multi dry-year event. However, the SCWA analysis states that conservative modeling
were used thatlikel overestimate the drawdown o
assumption'' • y f Lake Sonoma during the

and until mole definitive understanding of dry year supply and potential cutback

Table 444 lists the projected impacts to supply due to water quality issues. The only
projected impacts are to the groundwater supply where the Utility has experienced.sorne
water quality issues as discussed in Section 4.2. However, as WR &C is not projecting
using groundwater supply as a normal supply, there are no impacts to the supply quantity.
There are no projected impacts to the City's recycled water supply, though future

WR&C's P3 — Residential Survey ,covers this DMM. The Utility has offered plumbing
retrofit kits since 2002. This program distributes low-flow showerheads; faucet aerators,
and hose -end nozzles during the residential audits, at the WR &C, and at other ° public
information events.
WR &C also maintains another program relating to residential plumbing efficiency. P8-
High Efficiency) Faucets and Showerheads, requires all new residential construction and
remodels to install low -flow, showerheads and faucet aerators. This program is enforced
through the City's permit and building inspection services.
CoP UWMP FinaLdoc 32
City-of Petaluma
2010 Urban Water Management Plan
Implementation. WR &C: markets the program through its public outreach program. A
database'is "kept of each customer receiving retrofit kits along with other customer
specific information and notes. Customers with AMR meters whose meter shows a
potential leak are targeted for audits. Additionally, the top 1;000 water users are targeted
for audits and sent letters. The AMR customers and top water users are offered a $10 gift
certificate to'a local coffee house if they sign up for an audit. The Utility plans to
distribute 2;10 retrofit kits per year for the next five years.
Evaluation. Customer data is kept in the billing database and is used to evaluate impacts
of DMM on demands overtime. WR &C also monitors requests for retrofit kits over the
year and from year to year to identify customer trends and needs to improve the program.
The DMM requirement is to reach 75 percent saturation for all pre -1992 residential units.
Since beginning the program, 11,807 kits have been distributed. The Utility estimates the
program has reached an 81 percent saturation level. However, WR &C intends to
continue the program for the next five years.
5.3 DMM C — Leak Detection and Report
The Operations and Maintenance staff of WR &C conduct the efforts for this DMM.
Staff monitors production and sales records on a monthly basis to identify unaccounted
for water. Annual reports are also developed with unaccounted for water compared to
past years to trend and identify any potential issues. WR &C has been monitoring
unaccounted for water for at least the last 20 years. The unaccounted for water (not
including known non - revenue water) in 2010 was approximately 4.5 percent. WR &C
operations and conservation staff maintain the annual water audit program per the
AWWA Water Audit Model. WR &C adjusts its leak detection and repair activities based
on,real -time leak,frequency, audit results, and field observations. Currently, staff repairs
leaks as they are identified and monitor for specific leak patterns by location, material,
pressure and ,other parameters.
5.4 DMM D — Metering with Commodity Rates
This DMM is essentially part of the City's basic water service requirements.. All
customers are metered and charged using volumetric rates. The City. regularly evaluates
its rates structures and costs to provide water and adjust the service fee and volumetric
rates,accordingly
5.5 ° ' DMM E — Large Landscape Conservation Programs and Incentives
WR &C's P4 — Water Budget for Large Irrigators covers this DMM. The Utility offers
water budgets to all its irrigation account and large irrigation customers. Since the
program began in 2002, the Water Utility has developed 598 water budgets.
A site survey is conducted to develop the water budget. The site survey includes
measurement of landscape areas and plant type, irrigation system test, and a catch can test
on turf irrigation systems. The budget is developed. in a report that includes other
recommendations based on the site survey and also sources for additional information.
The customer's monthly irrigation budget is displayed on each bill_ with a comparison of

5.11 DMM K— Conservation Pricing
WR &C customers have always been metered and charged on volumetric rates. Expense .
and revenue4equirements are evaluated regularly and rates are adjusted to match
requirements for cost recovery. WR &C's current water rate structure contains a monthly
service charge and a tiered volumetric charge. There are four tiers for the residential
customers and one tier for all other customers. The wastewater rate also has two
components, a service charge and a volumetric charge based on the customer's winter
water usage.
WR &C's current rate structure results in volumetric revenues totaling approximately 85
percent of total revenue, which is in full compliance with the DMM. The Utility intends
to maintain this volumetric percentage in any modifications to its future rate structure.
5:12 I)MM L — Conservation, Coordinator
WR &C maintains a fulltime conservation coordinator. The position was established in
2006 The Utility also budgets for one full -time equivalent (FTE) to help implement the
conservation .program. The coordinator's duties include management and
implementation of the programs, budgeting and cost tracking, conducting site visits or
other audits, representing the program at public information events, customer demand
tracking, and others. Additional staff is utilized to assist in site visits and audits,
budgeting and planning water demand analysis, public information events and
campaigns, or other program implementation needs.
WR &C plans to continue to fund the conservation program staffing levels for one
coordinator and one FTE position.:for the next five years.

Water Shortage �Contingency,Plan (Appendix E) covers both short= term`emergency
shortages and long -term , supply reductions.
61 Demand to Supply Analysis
Normal year and dry year supply and demand scenarios are presented in Tables 6-1
through 6=3, As discussed in Section 4, the SCWA supply is not expected to be reduced .
during dry=year scenarios and WR &C projects the full supply °volume of 13,400 AF will
be available. SWRCB.Decision 1 regarding'SCWA's surface supplies does contain a
clause for up to 30 percent reduction during critically dry scenarios. However, as
described in Section 46 this scenario has never occurred. The Restructured Agreement
for Water „Supply,,contains provisions for supply reductions should the. D161.0 restrictions
be implemented; 'but due to the variable nature of'potential restriction amounts and length
of time; reductions are not quantifted.
WMC does not anticipate any supply ,reductions except under extreme circumstances
such as.catastrophic failure of SCWA's infrastructure. The Utility may decide to
temporarily reduce its demands and supply delivery during certain future conditions to
assist in addressing regional water supply and demand issues.

City of Petaluma 2010 Urban Water Management Plan
Appendix E
City of Petaluma Water Shortage Contingency Plan
1 Introduction
This Water Shortage Contingency Plan describes actions at each stage of shortage. The'
" Plan includes current water shortage emergency regulations that are located in Chapter
15, Section 18° of the City's Municipal Code and the Water Waste Ordinance that are .
documented in Section 15.1,2• of the Municipal Code. The current regulations ,are shown.
in Attachment 1. These will be enforced in event of a water.shortage. The
Water Shortage Contingency Plan builds upon the regulations specified in the Municipal
Code.
Petaluma's Urban. Water Shortage Contingency Plan addresses demand reduction
strategies for the Petaluma distribution system. The City's wholesaler, Sonoma County
Water Agency, determines trigger points on the Russian River system, which in turn
trigger Petaluma's program.
2 Water Supply,
The City receives its main water supply through a contract with the Sonoma County
Water Agency (SCWA).'The SCWA aqueduct system,delivers water from the Russian'
River`and from groundwater'wells in the Santa Rosa Plain to the City 'of ,Petaluma. The
supply agreernent,with SCWA provides that SCWA is contractually obligated to deliver
supplies, but is not obligated to 'provide supply in excess of 13,400 AFY and 21,.8 million
gallons'per day.
3 Drought /Em'ergency Planning Actions
In addition to responding'to. drought conditions, the'City's Water Shortage Contingency
Plan can be to respond to emergency.conditions that interrupt water ,supplies to the
City. Water supplies may �be interrupted in the future due to water supply ,coiitaminati`on,
rriajor transmission pipeline `break, regional power outage; or a natural disaster such as.,an
earthquake. In the event of an emergency, the Water Utility will respond as outlined in-
the current City of Petaluma's. Water System Emergency Response, Plan. Actions that'the
City would takejf these emergencies occurred todayare outlined below.
31 SCWA Supply. Interruption
In the event that SCWA's Russian River supply becomes contaminated (i.e. due to a "
chemical spill or other environmental incident) or is unavailable due to natural disaster, it
may be possible that no water would be available from SCWA for a period of time. In
such a case, the City would need to rely on water from system storage faciities and
emergency wells.. The. City will first determine existing storage supply, secure the
Kastania Storage Tanks, evaluate the potential length of supply shut down, then
CoP Water Shortage.doc 1
4/22/11
City 'of.Petaluma 2011 Water Shortage Contingency Plan
determine which water shortage, stage to declare. Once a water shortage stage is selected,
the City will implement the appropriate measures as defined in the stage description.
3.2 Power Failure
if an.area =wide electrical power failure, were to occur within the City's water service area,
many of the City's pumping facilities could potentially be impacted. Uninterruptible
power supplies are used at the Central Control and at each of the field sites, to power the
SCADA system. The battery is designed for approximately eight hours, which should be
sufficient time to return power or connect to a standby generator. Four portable
generators are available and have been used in the past to support power outage response.
SCWA's facilities may also be vulnerable to power outages; most of the SCWA facilities
which serve the City have backup power provisions.
3.3 Earthquake
Water system infrastructure, including pump stations, storage tanks, and pipelines, can be
damaged during a strong earthquake. The City's facilities have been constructed in
accordance with the applicable building codes to minimize potential damage during an
earthquake. Major reconstruction of existing facilities must also be designed to meet the
provisions of the Uniform Building Code for Seismic Zone 4. However, it is expected
that some facilities may be damaged as the result of a strong earthquake. The City has
multiple storage facilities and looped distribution pipelines, , to allow potentially damaged
portions of the City's system to be quickly isolated and repaired.
4 Water Shortage Stages
Demand reduction strategies will be employed at all stages of a water shortage
emergency. This section describes each stage and anticipated demand reductions. The
City may prioritize certain uses during a shortage stage such as,health and safety uses,
commercial or industrial needs, permanent or heritage landscape irrigation, or others.

CoP Water Shortage.doc 6
4/22/11
City�of'Petaluma 2011 Water Shortage Contingency Plan
Customer will be charged $250 for installation of pressure reducing service, and $250 for
removal device. Device will not be removed .unti customer has paid all fines arid. t
outstanding. account balances, and customer has been assigned a water budget:
Customer will, be charged,, $60 fortservice. disconnection and $60 -for re- connection.
Service will not be-re-connected until customer has paid all fines and outstanding account
balances, and customer has been assigned a water budget.
4.6 Impacts to Revenues
The City's rate structure is a combination of fixed connection fee and volumetric usage
charge: The'volumetric revenue from the 2040 rates structure is'estimated at 85 percent
of total revenue. Therefore, as higher demand reductions are required in the stages, the
volumetric revenue will also decrease. The City intends to address the reduced revenues
through a combination of water shortage surcharges and'use.of reserves. However, this
analysis is better addressed in the City's ongoing rate study and setting process. The next
proposed rate plan will include analysis and development of alternatives to meet short-
term and long -term water shortage. revenue reductions.
