EXHIBIT A-1
(SCOPE OF SERVICES)
The project scope generally consists of reviewing and updating the City’s 2005 PWMP. There have been changes to the City’s water infrastructure since the completion of the previous PWMP including development projects and implementation of Capital Improvement Program (CIP) projects. The tasks to be completed as part of this project are detailed and summarized below:
1) Project Management
2) Data Collection and Review
3) Land Use, Population and Planning
4) Water Supply
5) Water Demand Analysis
6) Planning Criteria
7) Hydraulic Model Update (modeling will be performed by City staff) 8) Existing System Evaluation
9) Future System Evaluation
10)Capital Improvement Program (CIP)
11) Program Environmental Impact Report (PEIR)
12) Sub Area Master Plan (SAMP) Template
13) Final Report
The intent of the PWMP Update is to create a living document addressing all the above items in a user-friendly format suitable for use by management, operations, and engineering to assist in the planning, funding, construction, and operation of water supply, treatment, and distribution facilities. Information shall be provided in a logical, easy-to-find format, either in the body of the report, or in appendices. Where appropriate, information shall be provided in tables, graphs, sketches, and photos.

The Consultant is to provide one or two of the consultant’s project members to work on City premises for the project duration. One of the consultant’s onsite project members will be responsible for creating the master plan exhibits, figures, and tables and performing data collections. Working on City premises will provide the team members the ability to access information more securely and communicate with City staff more frequently and as needed.

The City is currently adding the Info360 (Legacy SCADAWatch) software to its existing modeling, SCADA, and GIS software capabilities. Info360 will enable the City to have a realtime calibrated model including a monitoring and reporting dashboard. Info360 brings business intelligence into interaction processes in the control room. It enables water utilities to conduct zonal mass balance and water audits to determine non-revenue water and monitor everything from uptime to analytics, access timely information to make better decisions, react faster to important events and identify opportunities to drive operational efficiencies as they happen. It is a valuable system improvement, regulatory compliance tool, and financial planning tool.

City staff will be responsible for performing the hydraulic modeling using InfoWater and Info360 software. The Consultant shall work closely with City staff (Modeler) during the data collection task to gather data needed for modeling.

Info360 implementation will require approximately six (6) months. The Consultant shall include the Info360 schedule in the PWMP Update schedule by allowing the analysis and hydraulic modeling tasks to appear later within the schedule. The Info360 implementation is expected to be complete by July 2020. The maximum duration to fully complete this PWMP Update and PEIR shall NOT exceed 24 months.

TASK 1: PROJECT MANAGEMENT

1.6) Quality Control:

The Consultant’s Project Manager shall review all submittals prior to submitting to the City. Submittals that contain significant grammar and/or punctuation errors, or where the submittal has serious quality control issues, will not be accepted by the City.

TASK 2: DATA COLLECTION AND REVIEW
The purpose of this task is to collect, document and review any pertinent data to be used during this project, including operational conditions. The Consultant is to develop a Data Tracking List as part of this task to document the date/version of data collected and used so it is easy to perform future updates.

27157.11000\2955190.2
 Water supply studies
 Tanks, Pressure Reducing Stations/Valves, flow control, wells, and booster pumps data  Operational controls/SCADA set points
 Water Quality reports
 Pipeline repair/leak history
 Missing pipeline data (where available)
 Pressure zone boundary maps
 As-built drawings needed to update GIS
 Any other relevant planning documents
 Water Treatment as-built plans
All data collected shall be recorded in the Data Tracking List and logged for future use and reference. Where information appears outdated, it will be noted as such and the project team will determine if newer data is needed. The appendices include a portion of the documents listed above.

The Data Collection List shall be updated regularly and distributed with the Weekly Project Updates. A chapter in the final report shall identify all references used in the preparation of this master plan.

TASK 3: LAND USE, POPULATION AND PLANNING
The Consultant shall review previously compiled land use, population and planning data as part of Task 2 and utilize the most current land use, population, and planning information available.

One of the goals of this task is to characterize the type of water users that are part of the City’s water distribution system as of year 2019.

Some of the main components include:
 Update existing and future population estimates.
 Update existing and future land use information.
 Update City service boundary, existing and future water service areas (annexations or deannexations, etc.).  Calculate persons per household (pph) for existing and future conditions to determine where future growth and densification may occur.
 Hold on-going meetings/workshops with the City Planning Department to keep the PWMP Update and PEIR aligned with the General Plan, Specific Plans, etc. o Keeping the Planning Department engaged is a key element to making a master plan document that is accurate and accepted across various City departments.  Identify (from the Reclaimed Water Master Plan) locations suitable for conversion to reclaimed water service.

The effort completed during this task sets the foundation for all subsequent work during this project, so it is important to track the work in a logical and updateable manner. Utilize tools such as Geographic Information Systems (GIS) to develop or update existing land use and population datasets and document assumptions made. Once the information is collected, organized, and all parties agree on its validity, it will be used as the basis for completing the PWMP Update DocuSign Envelope ID: A60DB167-08E6-4EB0-A1DB-C271329F7F86 DocuSign Envelope ID: D88F2725-CE66-4947-9A94-14F899F17ABD DocuSign Envelope ID: 38717BA3-9F39-42F5-A559-C1AAE6836CC9 CA\DD\02000.50105\10005846.1

without further revisions. The master planning team will revise the data only in cases where the land use, population, or planning data will have a substantial effect on the modeling and planning results.

TASK 4: WATER SUPPLY
The City has a complicated water supply system with many operational variables that can change frequently, sometimes daily. Exhibit 2 is the water supply schematic. The Consultant shall meet with the City’s Department of Water and Power (DWP) Operations staff to knowledge-capture how they typically supply, treat, and deliver water to the system. While not every operational condition can be identified due to the complexity of the system, it is important that we document typical operations in order to conduct hydraulic model simulations and identify potential improvement projects.

The Consultant shall add a section to provide details about the well system, common well configuration, well collection system, how water travels from the wells to the Ion Exchange plant and the RO plant to the blending cells. Exhibit 3 shows the well collection system. The well collection system shall discuss the current water quality conditions, future projections and planning. Plan and recommendation shall cover current and future use of the Coldwater Basin.

The 2005 PWMP predicted a water supply deficiency for future conditions based on information and data collected at the time the plan was drafted. Part of this task is to determine if, given updated economic conditions and projections, a future deficiency is still anticipated. To determine this, the Consultant shall review and update the following items as part of this task:
 Water rights for groundwater (the Temescal basin is not adjudicated)  Hydrogeologic conditions of the Temescal, Bedford and Coldwater Creek basins (including water quality)
 Development of additional local groundwater supply, including treatment and delivery infrastructure required for beneficial use
 Future of groundwater and Colorado River water availability  State Water Project (SWP) entitlements
 Groundwater recharge using reclaimed water
 Groundwater recharge using stormwater capture
Another part of this task is to determine reliability of future water sources. The Consultant shall take a realistic approach to determining which water supply sources will be available in the future, and the quantity, quality and cost to supply water from the various sources. We will also investigate potential alternate sources of water and strategies if a future supply shortage is anticipated, such as:
 Water banking
 Water conservation and rationing
 Conjunctive use
 Purchase of additional SWP entitlements
 Stormwater recharge

10 (BB&K: 9-10)
27157.11000\2955190.2
The Consultant shall discuss the Direct Potable Reuse (DPR) as a potential future supply.

TASK 5: WATER DEMAND ANALYSIS
One of the key elements to having a defendable PWMP Update and CIP is proper allocation of water demands. The accuracy of the hydraulic model and resulting improvement projects is largely dependent on having the correct quantity and location of demands assigned in GIS. The Consultant shall establish a parcel-to-meter link as part of this task.

Once the parcel-to-meter link is established the Consultant shall use the monthly billing records for the past 5 calendar years (2014 through 2019). Due to the change in economic conditions it is important to look at the past 5 years to understand water usage characteristics in the City.

Existing demand shall be calculated from meter billing records for a calendar year which the project team agrees to be reflective of typical conditions and that forms a good basis for this master plan. After existing demand is calculated, the Consultant will update the Unit Flow Factors previously compiled in the 2005 PWMP.

Future water demand will be based on the General Plan zoning designations for the planning horizon (the current General Plan extends to year 2025) and population projections. The Consultant shall develop future demand by utilizing existing land use-based Unit Flow Factors and incorporating predicted population changes to determine the location and quantity of future demand in the City. The Consultant shall compare future demand projections with the water supply analysis completed as part of Task 4 to determine if water shortages are anticipated within the planning horizon. (Add “high-density urban” land use and determine water usage rate. The North Main apartments will provide some useful water use information for newly developed high-density apartment/condo developments.)
The Consultant shall estimate water loss in the system by comparing the past 5 years of water billing records with water supply/production records. For the hydraulic model, the water demand will be increased by the difference between the water production and billing records (typically 5- 10%) to simulate the realized flow the City’s water infrastructure experiences.

Updated average day and maximum day 24-hour diurnal usage patterns will be created as part of this task. For average day conditions, the sum of the area under the diurnal must be equal to 1 in order to obey the conservation of mass law. For maximum day conditions, the peak hour flow will occur at one point during the day.

The Consultant shall submit a draft chapter of the report that summarizes existing and future water demands. Information shall be presented in tabular and graphical formats. The submittal shall describe the process used to develop the projections. The Consultant shall present the demand projections to City staff in a workshop format. Consultant shall submit a final version of the report chapter that incorporates comments provided during the workshop or written comments provided during the review period. The final chapter shall be included in the final PWMP Update and PEIR report.

27157.11000\2955190.2
TASK 6: PLANNING CRITERIA
Planning criteria is used in the evaluation of both existing and future system hydraulic models. In general, the criteria from the 2005 PWMP will be updated, as needed, to meet any changes in municipal code or operational changes. General categories of criteria shall include the following:
• • Storage (including operational, fire protection, emergency, and blending) • • Pump Stations
• • System pressures under various demand conditions
• • Intra-zone water sharing
• • Inter-agency water sharing
• • Pipeline criteria (flow, velocities, head loss)
• • System redundancy and reliability
The Consultant shall document the planning and design criteria for this PWMP Update to analyze the existing water system and to evaluate recommended improvements. The criteria shall address the size of replacement, parallel, and new facilities for pipelines, pumping stations, storage facilities and regulating stations.

The Consultant shall develop unit costs to estimate Project Costs. Unit costs shall cover pipelines, pumping stations, storage facilities, regulating stations, and other improvements as appropriate. The unit costs shall incorporate cost information based on the City’s experience with similar facilities. Additional cost information available to the Consultant may also be used where appropriate.

The planning criteria shall be compiled in a separate chapter of the PWMP Update, generally in a tabular format, for easy identification and access.

The Consultant shall prepare and submit a draft Technical Memoranda that summarize the Planning Criteria and Unit Cost Criteria proposed by Consultant for this PWMP Update. The Consultant shall present this information to City staff in a workshop format. The Consultant shall submit the final versions of the Technical Memoranda that incorporate comments by the City provided during the workshop(s) or written comments provided during the review period. The final Technical Memoranda shall be included in an appendix to the final PWMP Update and PEIR report.

The Consultant shall develop planning level cost estimates for all recommended facilities. The cost estimates shall be based on a variety of cost data sources, such as City and other local project bidding history, and other sources reflecting cost of utility construction in southern California, adjusted to the then current ENR 20-City construction cost index, including appropriate contingency factors. Define other factors needed to generate Total Project Costs (soft costs). Construction and Total Project Costs shall be developed using the Unit Costs Technical Memorandum developed for this PWMP Update. Escalate costs to future years using historical construction cost inflation factors. Provide a summary of costs for each planning year, by service area. Present the cost summaries using tabular and graphical formats. The final report shall include a discussion of the basis for the cost estimates.

27157.11000\2955190.2
TASK 8: EXISTING SYSTEM EVALUATION
The Consultant shall utilize the results of the updated, calibrated hydraulic model to evaluate existing system hydraulics. The following core scenarios will be used as well as any subscenarios needed to evaluate the existing system hydraulic model:
 Existing Average Day Demands (7-day Extended Period Simulation (EPS))  Existing Maximum Day Demands (7-day EPS, which includes the Peak Hour in the diurnal)
 Existing Maximum Day Demands + Fire Flow (Steady-State) This set of scenarios and conditions provides a good basis for evaluating the existing system capacity and possible improvements resulting from the hydraulic model. The Consultant shall use the results from these scenarios to evaluate it against the Planning Criteria developed during Task 6. The Consultant shall produce maps/tables identifying facilities that do not meet criteria.

The Consultant shall handle the fire flow simulations in the following way:
1) One global Maximum Day Demand + Fire Flow Steady-State scenario shall be run to identify:
a. Nodes not meeting fire flow criteria
b. Critical nodes (i.e. bottleneck node(s) that may prevent other nodes from meeting fire flow criteria)
2) From the global fire flow simulation, identify nodes that need additional investigation, for example if nodes near hospitals or schools cannot deliver the required fire flow. These nodes will be evaluated in individual scenarios since Infowater does not display simulation details for a given single node during the global fire flow simulation as it is designed to look at system-wide results.

For any work involving fire flows, the Consultant shall consult with the fire department to request their input and requirements.

In addition to the model results, the Consultant shall evaluate other existing system parameters such as:
 Pump performance (SCE pump tests will be provided where available)  Tank type and design (inlet/outlet configuration, use of baffles, mixing, etc.)  Turnover time in tanks
 Pressure Reducing Valve (PRV) configurations
 • Flow control stations
 • Hydraulic settings of sub-zones supplied by pumping or by PRV’s  • Seasonal groundwater well operation scenarios
 • Blending facility operation to maximize use of local groundwater supply  • Desalter operation

27157.11000\2955190.2
 • Pipe distribution system materials, age, size, and history of leaks and repairs Facilities not meeting planning criteria in the model shall be flagged with a user-defined field explaining the reason. This will make developing and prioritizing the CIP more accurate since the reason for the recommendation will have been recorded at the time of evaluation.

As part of this task the Consultant shall perform a storage capacity analysis to determine if additional storage is needed, and where. This is likely to be done in a spreadsheet outside of the hydraulic model. As part of the storage capacity analysis we will account for any intra-zone water-sharing capabilities the City has. The storage surplus in one pressure zone can sometimes offset a storage deficit in another. Inter-agency connections and agreements for mutual support shall be described and presented in tabular format.

The Consultant shall also provide a narrative and graphical description of the well system, desalter, and blending system operation on a seasonal basis.

TASK 9: FUTURE SYSTEM EVALUATION
This task involves loading the existing system model with future (2025) demands and running simulations to identify where system improvements are needed during the planning horizon.

During this task, changes to some operational controls will likely be needed, as well as infrastructure improvements. In addition, the Consultant shall review prospective water conversion sites identified in the PWMP Update to determine potential reductions in potable water use. The following core scenarios shall be used as well as any sub-scenarios needed to evaluate the future system hydraulic model:
 2025 Average Day Demands (7-day EPS)
 2025 Maximum Day Demands (7-day EPS, which includes the Peak Hour in the diurnal) Results from these scenarios shall be evaluated against the Planning Criteria developed during Task 6. The Consultant shall produce maps/tables identifying facilities that do not meet criteria.

In addition to the model results, the Consultant shall evaluate other future system parameters such as:
 Pump capacity and controls
 Tank sizing and location (if new tanks are needed)
 Turnover time in tanks
 PRV configurations, sizing and location (if new PRVs are needed)  Hydraulic configuration of future sub-zones supplied by pumping or by PRV’s  Local groundwater development and future well locations  Changes to groundwater blending operation
 Wellhead treatment of nitrates
 Development of additional desalter facilities
 Providing redundancy in the distribution system to minimize customer service outages for planned and unplanned shutdowns

27157.11000\2955190.2
 Distribution system crossings of key infrastructure, such as freeways, railroad tracks, and storm drainage channels
Facilities not meeting planning criteria in the model shall be flagged with a user-defined field explaining the reason. Additional/future facilities input into the model shall be flagged as future facilities for easy tracking and identification in tables and figures. The storage capacity analysis developed as part of Task 8 shall be updated for future system conditions and demands. Like the existing system, the Consultant shall account for any intra-zone or inter-agency water-sharing capabilities the City possesses.

TASK 10: CAPITAL IMPROVEMENT PROGRAM
The results of the existing and future system evaluations done as part of Tasks 8 and 9, respectively, shall be grouped into logically constructible improvement projects as part of this task. It is important to vet across multiple departments and disciplines the recommendations produced from this effort, including management, to evaluate the feasibility of the recommended improvements. Projects requiring alignment changes or other edits will be addressed as part of this task.

The CIP shall include a desktop level analysis of available condition assessment information, such as any pump station and tank field condition evaluations previously performed. DWP Operations staff will assist with field visits to pump stations, valves, or tank sites as required to determine asset conditions. Information obtained through the Corona Enterprise Asset Management System (NEXGEN) shall be utilized where available. The PWMP Update effort is not a full condition assessment task like inspecting CCTV records for wastewater systems, but rather another layer of data to help prioritize facilities not meeting the planning criteria in either existing or future conditions.

Findings and recommendations from the 2005 PWMP shall be evaluated with the recommendations resulting from this project. The CIP shall be prioritized and phased over the planning horizon based on capacity, condition, financial feasibility, and economic feasibility needs with each project given a priority/ranking score. For example, nodes not meeting average day demand pressures in an area where pipe is greater than 50 years old would receive a higher priority than nodes not meeting average day demand pressures in an area with newer pipe, all else being equal.

The Consultant shall develop and use a prioritization matrix/ method to prioritize and schedule CIP projects. The prioritization matrix/ method shall be discussed, developed, and agreed upon with City staff and management.

Cost shall be assigned to each project based on a combination of references including, but not limited to recent local construction cost experience, Engineering News & Record Construction Cost Index (ENR CCI), cost estimating programs, and DWP staff input. The CIP will include tables with individual project costs phased over the planning horizon to establish a financial planning guide for the City.
