MEETING NOTES

I.   Work Plan


                                                                           Kickoff Meeting Minutes
                                                                                                 1
                                                                                            #5320
                                                                                     10/11/2006
      A. Project introduction and background information
           1.    The Temporary Impairment MOU that expires in 2008 has not been signed.
                 The previous MOU expired in 2005. The upcoming MOU allocates an average
                 day maximum month supply of 17.1 mgd to Petaluma through September 30,
                 2008. This allocation is assumed to remain constant throughout buildout for
                 this project.
           2.    The maximum month demand is the bottleneck due to the transmission
                 system, but soon the annual supply of 13,400 acre-feet per year will also be a
                 bottleneck.
           3.    From existing water conservation efforts implemented by the City, 63 million
                 gallons are saved annually. This project will conserve water in addition to that
                 of the existing efforts and the BMPs.
           4.    Some BMPs are not cost effective to implement such as ET controllers and
                 residential water audits. The City may wish to replace them with more cost
                 effective measures.
           5.    Projected water demands will be distributed to the project team prior to the
                 January 12, 2006 meeting.
      B. Project team
           1.    Steve Simmons, City of Petaluma, will attend all of the meetings.
           2.    Bartle Wells will attend Brainstorming/ User Group Meeting VI,
                 Implementation Plan per Tom Gaffney’s request.
           3.    George White will replace Michael Moore for representation of the
                 Community Development Department.
      C. Scope of work, project schedule, and budget
           1.    The project team discussed the scope of work, schedule, and budget as
                 outlined in the work plan.
           2.    Agendas and meeting minutes will be sent to all members of the project team.
           3.    Information required for the Brainstorming/ User Group meetings will be
                 sent prior to each meeting for all team members to review.
II.   Review Background Information
      A. A list of background information obtained to date was distributed. Background data
         items will be distributed to team members upon their request.
      B. Searching for additional resources
           1.    Many resources are available, and many studies of a similar nature have been
                 conducted. Data may be available from AWWARF, AWWA, etc.
      C. Additional resources
           1.    John Nelson’s "Zero Footprint Design for University District Specific Plan for
                 City of in Rohnert Park” was provided by Bill Maddaus. Bill supplied an
                 electronic copy to Dodson who will email the main document to the team
                 members.
                                                                             Kickoff Meeting Minutes
                                                                                                   2
                                                                                              #5320
                                                                                       10/11/2006
III.   Survey of Other Agencies' Water Conservation Programs
       A. SCWA Contractors are all doing the same thing. Santa Rosa's program is larger, but
          we want to go beyond what they are doing under this project.
       B. Extreme drought locations should be considered such as Las Vegas, El Paso, the
          Phoenix area, and Melbourne, Australia.
       C. Size of other cities or districts: The City of Petaluma is smaller and so it may be more
          applicable to survey smaller cities, yet some of the measures are scaleable and can be
          scaled to be applied to the City of Petaluma. Suburbs of large cities may be a good
          option.
       D. Survey should strive to locate innovative programs being implemented and
          ordinances that are in place.
       E. Discussions on potential agencies for survey included:
             1.    Irvine Ranch- innovative, but also well controlled and uniform based on the
                   Irvine Ranch design.
             2.    Windsor uses recycled water in the front yards.
             3.    Roseville
             4.    Santa Rosa: Green Homes
             5.    Pacific Grove, Carmel, Monterey, and the Marina Coast Water District are
                   facing limited water supplies.
             6.    Oceanside has a good landscape ordinance.
             7.    BMP's in Arizona are called RCM's. Can contact the Arizona Muncipal Water
                   Utilities Association.
       F. Background information
             1.    Water Transmission System PVP not relevant
             2.    Look for revisions of BMP Costs and Savings Study
       G. Interaction with developers
             1.    Ned asked if we should ask developers/ stakeholders their views so that they
                   participate early in the process. Bill commented that it is good to consult them
                   and let them know that whatever costs they pay will also be paid equitably by
                   other developers. Mike Ban and the community development department will
                   determine at what point to include the development community.
             2.    Mike talked about Christopherson "green building" homes in Santa Rosa that
                   gives the resident the choice to use recycled water given monetary incentives.
       H. Submetering- increases conservation in multifamily developments. The City of
          Petaluma does not currently submeter multi-family developments.
       I.   Survey development
             1.    Survey should concentrate on innovative programs for new development and
                   programs beyond the BMPs.

                                                                                Kickoff Meeting Minutes
                                                                                                      3
                                                                                                 #5320
                                                                                          10/11/2006
2.   Results will be sent via email before the next meeting.
3.   Give survey participants an incentive for participating. Offer to send them the
     results. We want them to be interested in what we are doing and to help us.
4.   Include questions about recycled water use, especially in residential areas.
5.   Funding source questions should distinguish between capital costs and O&M
     costs.
6.   Ask about water rate incentives.
7.   Ask about ordinances for water conservation and obtain a copy.

ACTION ITEMS

Dodson Engineers
♦     Obtain copy of Marin Municipal Water District AB 385 Landscape Standards.
♦     Compile water savings and cost data for onsite measures chosen at this brainstorming meeting.

MEETING NOTES

I.      Survey Results
        A.   Innovative ideas from other agencies were used in the discussion of potential onsite
             water conservation measures. Dodson Engineers will ensure that all good ideas
             implemented by other agencies are considered for implementation for Petaluma.
II.     Water Use Profile for Water Conservation
        A.   The General Plan and water use associated with the General Plan has not yet been made
             public knowledge and shall be considered confidential information until release of the
             General Plan and General Plan Environmental Impact Report.


                                                                                                                 1
                                                                                                              5320
                                                                                  Brainstorming Meeting I - Minutes
                                                                                                      1/31/2007
       B.   Water supply for the General Plan's water demands has not yet been defined and options
            are currently being explored under the Water Supply and Demand Analysis Project.
            These options include other supply/offset sources in addition to water conservation.
       C.   Potable water demands (indoor and outdoor) were discussed.
            1.    Potable water demands are based on 2002 water use. Water use from 2005 to 2025 is
                  based on the General Plan's land use in five year increments. Annual water use has
                  been interpolated between the five year increments.
            2.    Potable water demand projections include water use at the water reclamation
                  facility, changes due to the plumbing code, Coast Guard water use, anticipated
                  growth beyond the Urban Growth Boundary, and lost water. However the
                  breakdown of indoor and outdoor use does not include these demand elements
                  such water could not be divided into outdoor and indoor use.
       D.   Multifamily residences in the core area of the city will consist mostly of mixed use
            buildings of three or four stories with retail on the ground floor and residences above.
            Outside of the city core, residences consist mostly of townhomes and apartment
            buildings. Multifamily units consist of properties owned and rented.
III.   Onsite Water Conservation Measures
       A.   Attendees brainstormed potential water conservation measures for:
            1.    Single family residences (indoor and outdoor)
            2.    Multi-family residences (indoor and outdoor)
            3.    Commercial, Industrial, Office (indoor and outdoor)
            4.    Institutional (indoor and outdoor)
                  a.     There is no institutional support system for low water use. Government
                         institutions comply with state regulations for plumbing code rather than city
                         standards.
                  b.     A current lack of money and resources exists at institutions for changing
                         fixtures.
            5.    Turf
       B. Attendees were given 28 dots each to designate their preferred conservation measures for
          further evaluation.
            1.    Water conservation measures were identified and the associated number of votes
                  that each received is provided in the attached table.

        1. BMP goals are hard to apply for agencies outside of California, so a checkmark denotes a
           program that is not be included in the 14 BMPs developed by the CUWCC.
        2. Programs for onsite water use- outside of ordinances for new development
        3. Funding Mechanisms vary and so numbers correspond with funding mechanisms listed
           below:
           1) General Fund of City Budget
           2) Grants from wholesale water provider or government
           3) Fees and charges from water bill or connection charges
           4) Water permit application fees
           5) Fee from new development
           6) Fines for water waste

      rain shut off device and soil moisture sensors needed.
    o Landscape plan for areas > 1/2 acre have turf limitations, prohibit high water
      plants and decorative water features, and require an automatic irrigation system
      with shut off unit or soil moisture sensors, check valves, overhead irrigation
      restrictions, soil preparation requirements, 2" mulching requirement, and
      separate water meter for new landscapes using more than 81,463 gallons of
      water per year, and a water management requirement.
    o Water management requirement includes a warranty maintenance period where
      controllers are tested and adjusted, irrigation valves are checked, and irrigation

   as for medical buildings to use water conserving devices (Santa Monica).
• For low water using landscape, 3 components need to be in place: low water use
   plants, landscape and irrigation system design, and maintenance (SDCWA).
• Need to work with local nurseries to ensure that plants on list are available (El
   Paso).

ACTION ITEMS

City of Petaluma
•    Pamela will look into lot sizes for new single family residential developments near planned
     recycled water lines to explore the option of requiring dual plumbing to deliver tertiary treated
     recycled water to front yards or common areas once it is made available.

MEETING NOTES
I.   Water Demand and Supply Analysis Project Progress

      ♦   City of Petaluma Demand vs. Supply by Source
      ♦   Potential Potable Offset Tertiary Recycled Water Users
      ♦   Water Supply Project: Water Conservation Program C

          Water Agency
     A.    Information from the City of Petaluma Water Demand and Supply Analysis (WDSA) was
           passed out and discussed. The water conservation program builds upon the work being

                                                                                                                 1

                                                                                 Brainstorming Meeting II - Minutes
                                                                                                      1/31/2007
           performed under the WDSA project. Information about anticipated water demands,
           proposed programs for recycled water use (potable offset), and water conservation
           programs to meet water demands, were presented and discussed.
      B.   The recycled water program and the turf irrigation portions of the water conservation
           programs were coordinated to ensure no water conservation measures for potable water
           reductions were anticipated at proposed recycled water irrigation sites.
      C.   Water demands from the General Plan were based on proposed developments. The
           timing of recycled water and water conservation projects were initially based on
           maintaining a water supply slightly in excess of the water demand. Water supply
           projects can be implemented earlier or as needed to meet water demands through
           buildout in 2025 and beyond buildout.
      D.   Recycled Water
           1.   Anticipated recycled water customers were not included in projected potable water
                savings from water conservation measures since outdoor watering BMP's for
                recycled water would not provide potable water savings.
           2.   The potential for adding new recycled water users was discussed.
                     a.     The supply of tertiary treated water is greater than demand, and the
                            greater concern is using the recycled water since the City cannot
                            discharge into the Petaluma River in the summer.
                     b.     Recycled water service to front yards of individual residences was not
                            included as part of the potable water offset analysis. Pamela will look
                            into lot sizes for new single family residential developments near
                            planned recycled water lines to explore the option of requiring dual
                            plumbing to deliver tertiary treated recycled water to front yards or
                            common areas once it is made available. The City can also create
                            incentives for developers to install dual systems.
      E.   Water Conservation
           1.   Program C was chosen as the preferred water conservation alternative in the Water
                Supply and Demand Study.
           2.   Program C will expand current City BMP efforts and include the anticipated
                Sonoma County Water Agency Tier 2 water conservation measures. SCWA Tier 2
                measures are still in process of being specified. Some of the Tier 2 measures being
                considered by SCWA were not included in Program C, since Tier 2 measures have
                not yet been approved by the member agencies.
           3.   Water consumption monitoring at new development in both the City and the
                SCWA service area has typically found twenty percent more water use than similar
                existing development. The trend is that new houses consume more water, so
                Program C water conservation efforts bring the new single family water use to the
                same demand as existing single family residences.
           4.   Water savings estimates are conservative. We assumed some water customers will
                not participate in water conservation measures. If all customers participate, greater
                water use reductions may occur.

        ♦   Projected Potable Water Demands
        ♦   Indoor Residential Water Uses, Indoor Commercial and Institutional Water Uses,
            Outdoor Water Uses
       A.    Projected water uses through buildout (2025) are based on land uses from the General
             Plan. Water demand factors developed previously for the City of Petaluma were used
             and split into indoor and outdoor uses.
             1.    Land uses are based on parcels. With the example of a school, the parcel with the
                   classrooms and buildings are characterized as institution, while the playground
                   areas are characterized as turf.
       B.    End use distribution for baseline uses was determined on average for all customer types.
             Percentages of end uses are based on Bill’s previous work for the City of Petaluma.

III.   Onsite Water Conservation Measures

        Handout: City of Petaluma: Onsite Water Conservation Measures (Brainstorm Meeting I)

Onsite water conservation measures are defined as those that are targeted at new development and
are implemented through ordinances or the City entitlement process.
       A.    Attendees reviewed list of onsite water conservation measures developed from the last
             brainstorming meeting.
             1.    Water conservation measures that were included with water conservation Program
                   C developed for the WDSA Project were highlighted.

IV.    Offsite Water Conservation Measures

       Handout: Water Conservation Survey Highlights from 10 Agencies in the Western U.S.

Offsite water conservation measures are defined as those that are targeted at existing development
and water uses. These can be accomplished by retrofit or modification of existing water systems and
uses.

Attendees participated in a facilitated session to identify potential offsite conservation measures that
could be used in the City’s Water Conservation Plan.

       A. A list of categories was presented are for brainstorming purposes. This list was developed
          from the facilitated brainstorming session for on-site water conservation measures during
          our previous meeting.

       B. Previously identified measures were divided into the following three categories: Programs
          and/or retrofit; Ordinances and controls; and Public relations and billing. Separate listings
          for indoor and outdoor use were made for each category, creating six different categories.
          Each water conservation measure was assessed by attendees with regard to its suitability
          for offsite water conservation.

       C. Newly identified measures considered possible under each of the six categories were
          identified and assigned to specific water use sectors. Other agencies’ programs from the
          survey handout were also reviewed to include successful and implementable programs.




                                                                                                                   3
                                                                                                                5320
                                                                                   Brainstorming Meeting II - Minutes
                                                                                                        1/31/2007
     D. It was noted that many measures can overlap. For example, through ordinances CIO water
        saving devices can be implemented, although the device could be coupled with a rebate for
        equipment and installation.

     E. The results of the facilitated brainstorming session are listed in the attached tables (2
        pages). Measures highlighted in yellow are already included as part of Water Conservation
        Program C assumed in the Water Supply and Demand Study.

     F. All proposed measures will be evaluated against the screening criteria. The voting results
        from the previous brainstorming meeting will be used to develop some screening criteria in
        preparation for the next brainstorming meeting.

     G. The following items were discussed during the session :

          1.    Water reduction incentives and tiered water rates implementation methodology
                would need to be varied by customer type.

          2.    Implementation of a water management plan can be based on retrofit or renovation
                permits or after a certain date. Marin Municipal uses a change of name on the
                water bill, but this seems to target renters who are less inclined to replace fixtures.

          3.    A smart meter has been developed which continuously provides water meter
                reading to a remote device displayed within the home, such as on a refrigerator.
                The smart meter provides real time water usage data and leak detection by noting
                when small amounts of water are being used for a long period.

          4.    Dodson Engineers should refer to the EBMUD Business Efficiency Guide as a
                resource for water conservation measures.

          5.    Lower wastewater rates can also be an incentive to use water reducing equipment.
                The City bases wastewater rates on water billings.

          6.    Some cities have centralized water conservation information creating a one-stop
                shop for all approved equipment, rebates, approved contractors, and vendors.
                Seattle has a centralized website for water conserving equipment and related
                rebates. (Refer to www.savingwater.org). This could be an item more appropriate
                for a larger agency such as SCWA.

          7.    Retrofit of existing turf would occur upon replacement with artificial turf. Artificial
                turf can be used for turf areas further from the recycled water lines, where it is not
                feasible to extend those lines.

          8.    A low water use turf, called “Mow-free grass” has been developed and is currently
                being tested in areas of Southern California to determine cost-effectiveness. It is
                low water use and is relatively inexpensive when maintenance costs are
                considered. Rebates could be offered for turf conversions to this type of grass.

V.   User Group/ Brainstorming Meeting III - Develop Assumptions and Evaluation Criteria

     A. User Group/ Brainstorming Meeting III will be held on March 27 from 9 a.m. to 1 p.m. We
        will be discussing assumptions and evaluation criteria used to analyze potential water
        conservation projects developed at previous meetings and weights of evaluation criteria.

                                                                                                                 4

MEETING NOTES
I.   OVERVIEW AND GOALS

     Handout: Evaluation Criteria Listing and Rating Form
     A.    Review Project Goals
           1.   Goal to complement and work in parallel with the Water Demand and
                Supply Analysis Project and the Sonoma County Water Agency
                (SCWA) conservation efforts in the Urban Water Management Plan.
                     a.     Water Conservation Program C focuses mostly on offsite
                            projects.
                     b.     SCWA efforts are based on their Urban Water
                            Management Plan. The SCWA program will be funded by
                            current water rates.



                                                  Brainstorming/User Group Meeting III- Minutes
                                                                                              1
                                                                                          #5320
                                                                                      1/31/2007
                      c.     Developer pays for programs to offset water demands due
                             to their development and pay for offsite efforts based on
                             expected water demands with onsite measures.
                             Connection fees will pay for the water conservation plan
                             (this program).
            2.   Goal of water conservation plan to complement General Plan
                      a.     Water conservation as a contingency for recycled water
                             and Program C in the Water Demand and Supply Study.
                      b.     Eliminate the use of the wells in the future
            3.   Goal of the water conservation plan to provide 240 million gallons per
                 year (MGY) by the year 2025.
                      a.     25% of water conservation efforts under Program C: 62.5
                             MGY
                      b.     25% of recycled water demands: 116 MGY
                      c.     100% of wells: 61 MGY
            4.   Balance of outdoor and indoor water conservation projects to decrease
                 summer peak demands and total annual demand.
      B.    Review of Project Progress
            1.   BSM1 - Onsite measures development
            2.   BSM2 – Offsite measures development
      C.    Goals for BSM3
            1.   Limit number of evaluation criteria and combine similar criteria.
            2.   Identify fatal flaws for criteria where possible to reduce number of
                 water conservation measures from previous brainstorming meetings.

           4.    SCWA – Tier 2 and New Development (ND) Measures
      B.   Three programs consisting of a varying number of water conservation measures (to be
           agreed upon Today) will be evaluated using the DSS model by Maddaus Water
           Management.
           1.    The DSS model provides the following advantages:
                 a. All prior work performed in DSS model by Maddaus Water Management.
                 b. Accounts for the effects of all measures as a complete program. Measures are
                    not additive.
                 c. Provides program costs by year (total cost, capital cost (City and developer)
                    and operating cost) Essential for use by Bartle Wells in Funding Mechanism
                    Development.
                 d. Provides water savings by year. Annual water savings (total, indoor and
                    outdoor savings) and ADMM water savings.
      C.   All water conservation measures and their associated implementation rate must have
           buy-in by City Staff for success. City staff to select measures – other to provide
           information and assistance.

       B.   Tier 1 (SCWA) = 106 MG/Y
       C.   Tier 2 (SCWA) = 86 MG/Y
       D.   New Development (SCWA) = 167 MG/Y
       E.   Tier 1 & Tier 2 (SCWA) = 180 MG/Y
       F.   Tier 1 & New Development (SCWA) = 255 MG/Y
       G.   Tier 1 & Tier 2 & New Development (SCWA) = 343 MG/Y

IV.    WATER CONSERVATION PLAN - POTENTIAL WATER CONSERVATION MEASURES
       (POST FATAL FLAW ANALYSIS)
       A.   Results of Fatal Flaw Analysis
            1.   Fatal flaws
                 a.   Relative cost: More than the cost of desalination of the Petaluma River ($2000/
                      AF, $6000/ MG)
                 b.   Responsibility of cost burden and proposed beneficiaries: Excessive developer
                      fees compared to nearby agencies
                 c.   Performance records: Has not been previously tested and has no performance
                      data
                 d.   Appropriate for community: Not appropriate for community and customer
                      types
                 e.   Legality: Does not meet health standards
                 f.   Annual expected water savings: Does not meet 5% of total expected water
                      savings goal (12 MGY)
                 g.   Convenience of use: No relative advantage, less attractive than present

MEETING NOTES

I.   PROJECT DIRECTION
     A.    Discussed current and prior efforts for water conservation of the City. They will be
           evaluated and combined to create a stand alone comprehensive program for the
           City. These efforts include
           1.    Water Demand and Supply Project: Program C
                 a.    Includes recycled water to areas A,C,E,G
           2.    CUWCC MOU BMP’s (SCWA Tier 1)
           3.    SCWA Tier 2 and New Development Measures
           4.    Water Conservation Plan efforts from prior Brainstorming/ User Group
                 Meetings
     B.    Discussed water savings results and assumptions for each of the items above.
           1.    Program C (Petaluma – Water Demand & Supply Project) = 255 MG/Y

                                                                           Brainstorming Meeting VI- Minutes
                                                                                                           1
                                                                                                      #5320
                                                                                                1/31/2007
            2.     Tier 1 (SCWA) = 106 MG/Y
            3.     Tier 2 (SCWA) = 86 MG/Y
            4.     New Development (SCWA) = 167 MG/Y
            5.     Tier 1 & Tier 2 (SCWA) = 180 MG/Y
            6.     Tier 1 & New Development (SCWA) = 255 MG/Y
            7.     Tier 1 & Tier 2 & New Development (SCWA) = 343 MG/Y
       C.   Measures can be adjusted in terms of implementation level and customer sectors
            impacted so that the most effective measures for the City can be implemented.
       D.   Use of the DSS model as a predictive model for water savings and cost. The DSS
            model provides the following advantages:
            1.     All prior work performed in DSS model by Maddaus Water Management.
            2.     Accounts for the effects of all measures as a complete program. Measures are
                   not additive.
            3.     Model provides program costs by year (total cost, capital cost for the City and
                   developer, and operating cost), which is essential for use by Bartle Wells in
                   Funding Mechanism Development.
            4.     Model provides water savings by year. Annual water savings (total, indoor
                   and outdoor savings) and ADMM water savings.

II.    WATER CONSERVATION PLAN GOALS
       A.   Requirement for Water Demand and Supply Project = 255 MG/Y (at Buildout 2025)
            and 1.31 mgd ADMM (minimum requirement)
       B.   Additional Goal (per Brainstorming/User Group Meeting III) = 240.5 MG/Y
            1.     25% of Water Conservation requirement = 63.75 MG/Y
            2.     25% of Recycled Water requirement = 116 MG/Y
            3.     100% of Groundwater requirement = 60.75 MG/Y
       C.   TOTAL GOAL = 495.5 MG/Y
       D.   Conservation goal of 495.5 MG/Y confirmed for the water conservation plan.

III.   CLARIFICATIONS AND ASSUMPTIONS
       A.   Residential multifamily is defined as those with 3 or more units. A duplex will be
            considered to be in the single family category.
       B.   Cost benefit ratios from the DSS analysis uses the perspective of the customer and
            utility. Energy benefits and savings from a decrease in the amount of generated
            wastewater are not included.
       C.   DSS compares the cost of water from water conservation to those of purchasing
            water from SCWA in 2005, not including the distribution cost. Actual cost
            comparison to SCWA water should be based on the following information:
            1.     POTABLE WATER COST                $/acre-ft              $/MG
                   SCWA                              $432.68                $1,324.00
                   City Distribution Cost            $437.09                $1,337.50
                 TOTAL COST                          $869.77/acre-ft        $2,661.50/MG

                                                                             Brainstorming Meeting VI- Minutes
                                                                                                             2
                                                                                                        #5320
                                                                                                  1/31/2007
      D.   Resale rate of residences assumed to be 5% per year.
      E.   State and Federal requirements for water efficient appliances are expected, but
           when appliances will be available at stores is unknown.
      F.   Program shall being in Year 2008.
      G.   Work shall assume recycled water distributed to Areas A,C,E,G.
      H.   Cost to Developers must be provided as an end product as well as costs to the City.
           Both costs are required to determine overall capital program costs.

IV.   PROGRAM DEVELOPMENT/CONSERVATION MEASURE SELECTION
      A.   City chose measures and implementation percentages for each level of water
           conservation program (minimum, medium, and maximum). Attachment shows
           results of Brainstorming Meetings and water conservation measures to be included
           in the DSS modeling.
      B.   David is currently drafting a new landscape ordinance. David to send draft
           ordinance to project team.
      C.   City to obtain license for the use of the DSS Model from the CUWCC. Bill can train
           and familiarize David and May with the model.
      D.   Project team to project water savings and cost for measures chosen. Bill will
           augment if the model does not project water savings to meet the goal of 495.5
           MG/Y.

V.    NEXT MEETING – BRAINSTORMING/USER GROUP MEETING V
      A.   Brainstorming/Usergroup Meeting V is scheduled for Monday, August 28, 2006
           from 9 a.m. – 1 p.m.
      B.   Results of DSS Model Analysis for proposed Water Conservation Program(s) and
           agree upon program to be implemented.

I.   CONSERVATION PROGRAM DEVELOPMENT/EVALUATION

     A.   Three programs consisting of a varying number of water conservation measures as
          agreed upon at Brainstorming/User Group Meeting IV (July 17, 2006) were evaluated
          using the DSS model by Maddaus Water Management.
          1.    Minimum Program = Program 1
          2.    Medium Program = Program 2
          3.    Maximum Program = Program 3
     B.   Three programs consisting of a varying number of water conservation measures (to be
          agreed upon Today) will be evaluated using the DSS model by Maddaus Water
          Management.
          1.    Water savings (in 2025):
                a. Program 1 = 504 MG/Y
                b. Program 2 = 537 MG/Y
                c. Program 3 = 562 MG/Y
          2.    Water savings goals for Program:
                a.   Requirement for Water Demand and Supply Project = 255 MG/Y (at Buildout
                     2025) and 1.31 mgd ADMM (minimum requirement)

                b.   Additional Goal for Water Conservation Plan project (per Brainstorming/User
                     Group Meeting III) = 240.5 MG/Y
                       (1) 25% of Water Conservation requirement = 63.75 MG/Y
                       (2) 25% of Recycled Water requirement = 116 MG/Y
                       (3) 100% of Groundwater requirement = 60.75 MG/Y
                       (4) TOTAL GOAL = 495.5 MG/Y

MEETING NOTES
I.        CONSERVATION PROGRAM PROGRESS
          A.   Three programs consisting of a varying number of water conservation measures as
               agreed upon at Brainstorming/User Group Meeting IV (July 17, 2006) were evaluated
               using the DSS model by Maddaus Water Management.
               1.    Minimum Program = Program 1
               2.    Medium Program = Program 2
               3.    Maximum Program = Program 3
               4.    From the DSS model, water savings (in 2025) were forecasted to be:
                         a.    Program 1 = 504 MG/Y
                         b.    Program 2 = 537 MG/Y
                         c.    Program 3 = 562 MG/Y
          B.   Water savings goals for Water Conservation Program:
               1.    Minimum Requirement for Water Demand and Supply Project = 255 MG/Y (at
                     Buildout 2025) and 1.31 mgd ADMM
               2.    Additional Goal for Water Conservation Plan Project (per Brainstorming/User
                     Group Meeting III) = 240.5 MG/Y

                                                                Brainstorming/User Group Meeting Additional - Minutes
                                                                                                                    1
                                                                                                               #5320
                                                                                                         8/27/2007
                    a.  25% of Water Conservation requirement = 63.75 MG/Y
                    b.  25% of Recycled Water requirement = 116 MG/Y
                    c.  100% of Groundwater requirement = 60.75 MG/Y
           3.    TOTAL GOAL = 495.5 MG/Y
II.   PROGRAM EVALUATION
      A.   Description of Conservation Measures in DSS Model
           1.   Descriptions of the twenty eight modeled measures and their associated impacted
                customer sectors are described in Table: “Measures for the City of Petaluma Water
                Conservation Plan”.
      B.   Conservation Measure Program Inclusion (Program 1, 2, and 3)
           1.   Twenty eight measures were modeled in the DSS model. A list of measures and the
                programs where each of the measures are included, is provided in Table: “Selected
                Conservation Measures for Water Conservation Programs (1, 2, and 3)”.
      C.   Program Water Savings with Time (2008 – Buildout (2025))
           1.   In Graph: “Petaluma Program Water Savings vs. Time”, forecasted water savings
                resulting from Programs 1, 2, and 3 were compared to one another as well as Tier
                One To-Date and Tier 1 Future. Tier One to-Date shows water savings resulting
                from already implemented Best Management Practices (BMP’s) of the CUWCC.
                Tier One Future shows the water savings if the City continues to only implement the
                BMP’s.
      D.   Conservation Measure Model Input Data Included:
           1.   Market penetration – percentage of accounts that will be impacted
           2.   Measure length to reach goal – years to reach market penetration goal
           3.   Measure life – length of time where measure will continue to save water
           4.   Year to begin measure - start year of measure implementation
           5.   Water use reductions - anticipated reduction in end use water demand
           6.   End use - use of water that measure impacts such as toilet, laundry, irrigation, etc.
           7.   Program length - duration of water conservation measure program
           8.   Utility unit cost - cost for water utility to implement measure
           9.   Customer unit cost – cost for customer to implement measure such as installing new
                equipment (includes developer cost)
           10. Annual administration/ marketing cost – mark-up in utility cost to publicize and
                implement measure
      E.   Conservation Measure Benefit Ratios & Cost ($/MG)
           1.   Based on the utility and customer benefit-cost ratios, measures can be compared to
                one another. These are based on the cost to save water and other benefits to the
                community such as reduced energy costs.
                     a.      The water utility benefit-cost ratio includes the cost to only the utility.
                     b.      The Utility/Developer benefit- cost ratio includes the cost for the utility
                             and the developer.


                                                               Brainstorming/User Group Meeting Additional - Minutes
                                                                                                                   2
                                                                                                              #5320
                                                                                                        8/27/2007
                      c.     The Community benefit-cost ratio includes the cost to the City,
                             Developer, and Community. The higher the benefit-cost ratio, the more
                             cost effective the measures are.
       F.   80 Year Present Worth Analysis
            1.   Results are shown in Table: ”Summary of Results: Petaluma with Recycled
                 Options”. Two 80 year present worth analyses were prepared.
                      a.     Utility: Includes all capital and operations costs to the City. The costs to
                             the developers are not included.
                      b.     Utility + Developer: Includes all capital and operations costs to the City
                             and the developers.
III.   PROGRAM SELECTION
       A.   Since the City goal of 495.5 MG/Y was exceeded, screening criteria was used to limit the
            number of measures to match the goal of 495 MG/Y. Screening criteria included cost,
            implementation ease, and public acceptance.
       B.   Nine measures were removed.
            1.    Eight measures were removed due to the high cost per unit of water saved. They
                  include: New Efficient Dishwasher Requirement, Hot Water System, Direct
                  Installation of HET’s, Smart Irrigation Controller Rebates for Single Family
                  Residences, Waterless Urinal Rebate, 0.5 gpf or Waterless Urinal Requirement,
                  Reduced Connection Fees for Selected Businesses, and CIO Rebates.
            2.    One measure was removed due to difficulty to implement: Financial Incentives for
                  Irrigation Upgrades
            3.    Nineteen measures remain.
                       a.      Two measures were kept despite the high cost of water saved due to
                               public and political acceptance. They include Landscape and Irrigation
                               Requirements and Plan Check for Renovation and for New

           May Zhao, Dodson Engineers

ACTION ITEMS
     Dana Hunt
     1.    Provide capital cost figure to Bartle Wells for the Water Conservation Plan and the water
           savings amount due to water conservation and recycled water without the contingencies.
           This reflects the amount of water needed to meet project demands.
     Bartle Wells
     1.    Prepare connection fee report for the plan as an appendix including language for ordinances
           for connection fees based on expected water demand rather than meter size.
     Dave Iribarne
     1.    Provide estimate of additional staffing costs for the recommended water conservation
           program.

MEETING - AGENDA ITEMS
I.        BACKGROUND INFORMATION
          A.  Water Conservation Plan Administrative Draft’s recommended water conservation
              program, including all cost impacts to the City and development community
               1. Water supply cost to the City decreases compared to the cost to supply water based on
                  the Water Demand and Supply Analysis, but developer cost increases due to the
                  increased cost for water efficient items at new development. This cost is lower on an


                                                                                         Water Conservation Plan
                                                               Brainstorming Meeting- Funding Mechanism Minutes
                                                                                                               1
                                                                                                           5320
               80 year present worth basis than the cost for new water supply such as from
               groundwater wells, recycled water, or purchased from SCWA.
       B.   Differences between prior Water Demand and Supply Analysis work and Water
            Conservation Plan work, including total cost of new water supply and development fee
            impacts
            1. The expected water conservation savings for the recommended water conservation
               program goes above and beyond the water conservation Program C recommended in
               the Water Demand and Supply Analysis Report and in the General Plan.
            2. For cost/ water saved figure, use the “firm yield” amount, 779 MG/Year, which does
               not include contingencies. This is the amount of water needed for which the
               developers are paying. The contingency amount ensures that the supply is reliable.

II.    DISCUSSION
       A.  Operations cost may not include additional cost for staffing and overhead. This is not
           added to the connection fee, but used to calculate water rates. Dave to provide estimate
           of additional staffing costs for the recommended water conservation program.
       B.   Plan check procedures can be coordinated with the Community Development
            Department so that when they inspect a building, the water conservation measures can
            be incorporated with the inspection.
       C.   Bartle Wells to provide a report to City on connection fees based on the recommended
            water conservation program.
            1. One idea is that connection fees may be based on capacity rather than meter size. If a
               customer exceeds their capacity, the City can charge a surcharge lease fee for the
               water exceeded.
            2. North Marin Water District has an ordinance that shows a maximum rate that the
               customer is entitled to based on the connection fee. Bartle Wells to include ordinance
               language similar to that of the North Marin Water District.

III.   NEXT STEPS
       A.  Bartle Wells to provide report. Dana to incorporate this into the Water Conservation Plan
           report and implementation information.
       B.   Dana to add Appendix K entitled Water Supply Project to the report to show that the
            connection fee includes recycled water and water conservation.
       C.   An Administrative Draft will be submitted to Margaret. Margaret wants City to review
            the Administrative Draft with the developer community before the draft goes to the City
            Council.
