Recommended Action: It is recommended that the City Council authorize the City Manager to approve and execute the Sixth Amendment to the Agreement with Infrastructure Engineering Corporation (IEC) for Engineering Services during the Bid and Construction Phases of the Clearwell Bypass Project per the terms outlined in the Agreement. Discussion: On May 7, 2019, the City Council approved an agreement with Infrastructure Engineering Corporation (IEC) for design services of the Clearwell Upgrades Project for a not-to-exceed amount of $385,821.00 (Attachment A). The title of the project has since changed to the "Clearwell Bypass Project". As we've further refined the scope of the project, additional design services were needed for the additional components of the project. The original scope of the project consisted of the replacement of the clearwell cover, as well as preliminary site assessments for the development of future maintenance/rehabilitation projects at the clearwell. Subsequent assessments determined that the clearwell liner is also in need of replacement. The design scope was then revised to include the replacement of the liner. Further analysis also determined that the overflow structure needs to be replaced. The Clearwell Bypass Project's scope was developed to enable the replacement of the clearwell by bypassing it. Subsequent amendments to the agreement include the following changes: 1 of 151

Box 789, Poway, California 92074-0789 www.poway.org
April 20, 2021, Item #5Amendment No. 1 City of Poway Clearwell Upgrade Project Scope of Services BACKGROUND•••••••••••••••••••••••••••••••••••••••••••••••••••••• The City of Poway (City) has engaged Infrastructure Engineering Corporation (IEC) via an agreement dated May 15, 2019 to provide engineering services in support of a project to replace the floating cover on the Clearwell at the Lester J. Berglund Water Treatment Plant (WTP). Per the original scope of services, IEC has previously prepared and submitted the 50% design for replacement of the Clearwell floating cover only and provided a draft assessment report describing other key Clearwell components. The results of the assessment are that the geomembrane liner in the Clearwell has reached the end of its useful life and should be replaced at the same time as the floating cover. The assessment also notes that the six (6) concrete inlet/outlet structures in the Clearwell should be rehabilitated at the same time. Based on this information, the City has elected to revise the original project approach to have the floating cover, geomembrane liner and other project components described above replaced as part of the same project. This Amendment No. 1 describes the changes and additions in scope and fee for IEC to address these changes to the project. All tasks are directed to IEC unless otherwise noted. Changes and additions to the original scope tasks are described below. SCOPE OF SERVICES••••••••••••••••••••••••••••••••••••••••••••••••••••• TASK l -PROJECT KICK-OFF AND DATA COLLECTION-------------Review available documentation, reports, and record drawings pertinent to the geomembrane liner and inlet/outlet structures. Develop revised approach to construction of combined cover and liner. TASK 2 - CLEARWELL ASSESSMENT-------------------2.1 -ULTRASONIC TESTING INVESTIGATION OF EFFLUENT PIPELINE Provide confined space entry support services during field investigation of effluent pipe in below grade gallery. 2.2 -MATERIAL TESTING OF CLEARWELL GEOMEMBRANE LINER AND FLOATING COVER No additional services anticipated regarding the geomembrane liner. At the same time as the geomembrane liner material is sampled, obtain coupons of the Hypalon floating cover at two (2) locations and have them tested for thickness, tensile strength, tensile elongation, tear strength, hydrostatic resistance, ply adhesion, water absorption, and surface cracking. Repairs to the existing floating cover and geomembrane liner will be performed by City staff or a geomembrane specialty contractor engaged by the City. 2.3 -FACILITY INVENTORY AND ASSESSMENT Incorporate the results of the Hypalon floating cover material test results (from Task 2.2) in the Assessment Report and discuss in the report the potential need for replacement of the geomembrane liner. Add discussion in the report regarding the option of replacing the geomembrane liner at the same time as the floating cover. Submit the draft and final report per the original Scope of Services. 31 of 151
April 20, 2021, Item #5SCOPE OF SERVICES Provide opinion of construction cost estimate for project that combines floating cover and geomembrane liner replacement. Prepare and submit concept level construction cost estimate for a bypass pipeline that provides a direct connection between the WTP and the distribution system piping during an extended shutdown of the Clearwell. Present cost estimates in a technical memorandum that includes a description of the pipeline alignment and considers 20", 24" and 36" pipeline diameters. TASK 3 -DESIGN------------------------3.1 -PLANS, SPECIFICATIONS AND ESTIMATE Prepare plans, specifications, and engineer's opinion of probable construction cost estimates (PS&E) with the addition of the geomembrane liner and modifications to the six (6) concrete inlet/outlet structures. The expanded plan set is estimated to include the following drawings: • Two (2) General sheets including a title sheet, list of abbreviations, legend, general notes and key map • Two (2) Floating Cover and Geomembrane Liner Notes • One (1) Demolition Plan • One (1) Construction Sequence Plan • Thirty-three {33) Floating Cover and Geomembrane Liner Plan and Details • Three (3) Inlet/Outlet/Overflow Structure Modification Details • Five (5) Electrical Notes, Plan and Details • Three (3) Erosion Control Plan and Details Where practical, the PS&E will be prepared using the portions of the previously prepared 50% PS&E (from the floating cover only replacement design). The previously submitted 50% design package will be revised to include the geomembrane liner and resubmitted. The PS&E will be prepared and submitted according to the parameters described in the original Scope of Services. 3.2 -DESIGN COORDINATION MEETINGS Prior to the start of the expanded design effort, prepare for and attend a meeting with the City to discuss the project elements and construction approach for replacement of the floating cover and geomembrane liner. The goal of this meeting is to reach concurrence on the project elements to be carried forward in the design. TASK 4 -DDW COORDINATION Provide additional support services to coordinate the revised project with the California State Water Resources Board -Division of Drinking Water (DOW). This may include up to one additional meeting (with DOW and cover/liner designer on conference call). Provide these services on a time and materials basis up to the level of effort defined in the task budget. City of Poway Scope of Services for Clearwell Upgrades Project 32 of 151 2
April 20, 2021, Item #5SCOPE OF SERVICES TASK 5 -PROJECT MANAGEMENT DURING DESIGN--------------Coordinate with the City to define the expanded project components, administer the project scope and budget adjustments and subconsultant contracts, and manage the project for the extended project schedule and additional services. TASK 6 -ENGINEERlr"~G SUPPORT DURING BID AND CONSTRUCTION PHASES------6. l -ENGINEERING SUPPORT DURING BID PHASE No additional services anticipated. The support services will be provided up to the level of effort defined in the task budget. 6.2 -ENGINEERING SUPPORT DURING CONSTRUCITON PHASE These support services are in addition to those in the original Scope of Services and will be provided on a time and materials basis up to the level of effort defined in the task budget. • Floating cover / liner designer will distribute the previously budgeted site visits during the liner and cover construction at various stages. • Estimate up to ten (10) submittal item reviews and re-reviews associated with the liner. • Estimate up to two (2) responses to change orders, field orders, and RFls associated with the liner. • Prepare record drawings for additional drawings. • Provide project management services during extended construction phase to account for liner. TASK 7 -CONSTRUCTION INSPECTION-----------------The services described in the original Scope of Services are unchanged. The level of effort estimated for this task is revised to add time for the longer construction period associated with the addition of the liner replacement: two (2) additional months for preparation, procurement and fabrication of the liner, and liner demolition and combined cover and liner installation. This renders an overall construction period of up to nine (9) months total. The period of onsite part time inspection is extended by six (6) weeks to allow for the combined cover and liner installation. The services will be provided on a time and materials basis up to the level of effort defined in the task budget. SCHEDULE•••••••••••••••••••••••••••••••••••••••••••••••••••••••• Based on City approval of this Amendment before December 31, 2019, assuming timely concurrence on the project design elements, timely scheduling of meeting and responses for information, and allowing two (2) weeks for submittal reviews by the City, the estimated delivery of the final PS&E submittal is twenty-four (24) weeks from the approval of the amendment. Intermediate PS&E submittal deadlines will be coordinated with the City following amendment approval. The schedule for Tasks 6 and 7, support during the Bid and Construction Phases, will depend on the City's actual schedule for the bidding, award and construction phases. The scope and budget for these services assumes that project construction will be completed by June 2021. If the project extends beyond these periods, IEC will have the opportunity to revise rates accordingly. City of Poway Scope of Services for Clearwell Upgrades Project 33 of 151 3

Hilts Consulting Group (HCG) was retained by IEC to provide professional engineering services for the floating cover portions of the project, as detailed in the original agreement. As part of the original scope or work and as a result of the existing HDPE liner material investigations there is sufficient evidence to suggest the existing liner material may be at or near the end of its useful life and highly doubtful the existing liner is adequate to expect an additional 20 years or more of service life to coincide with the anticipated life of the proposed replacement floating cover. To provide the City additional information to assess an alternate project implementation strategy, HCG proposes material testing be performed on the existing Hypalon floating cover material. The purpose of the material testing is to estimate the additional remaining life for the existing floating cover material and in turn provide the City additional time to plan and implement the necessary measures to accommodate a clearwell liner and floating cover replacement. Scope of Work: HCG will provide coordination and collaboration with IEC and 3rd party geomembrane material testing laboratory. HCG has (2) existing Hypalon floating cover material samples obtained as a result of the prior existing HDPE liner material acquisition. The floating cover samples are above the reservoir normal water level and from the north and west side slopes.

Proposed tests include thickness, tensile strength, tensile elongation, tear strength, hydrostatic resistance, ply adhesion, water absorption, and surface cracking. HCG will review 3rd party laboratory test results and provide professional opinion on the condition of the existing Hypalon floating cover material. PROFESSIONAL FEES The professional fees for scope of work defined above are proposed on a time and materials basis with an estimated $6,000 not to exceed amount. The fee associated with the additional work is comprised of 12 hours of HCG involvement plus the 3rd party laboratory testing and associated markup. At the direction of IEC, additional services may be performed and shall be based on the hourly rates in the attached fee schedules plus reimbursable expenses. Please review this change order proposal and if acceptable forward an agreement amendment so the above work may be initiated. HCG appreciates the opportunity to continue collaborating with the IEC on the City of Poway, Clearwell Upgrades Project.

Hilts Consulting Group (HCG) was retained by IEC to provide professional engineering services for the floating cover portions of the project, as detailed in the original agreement. As part of the original scope or work and as a result of the existing HDPE liner material investigations there is sufficient evidence to suggest the existing liner material may be at or near the end of its useful life and highly doubtful the existing liner is adequate to expect an additional 20 years or more of service life to coincide with the anticipated life of the proposed replacement floating cover. The City has requested a proposal to include professional engineering services for a replacement geomembrane liner. Scope of Work: The geomembrane liner is envisioned to be a 45 mil, 3 ply, CSPE geomembrane liner material supported on a nonwoven geotextile laid over the existing asphalt plank lining system. Work may include minor modifications to existing hydraulic structures located within the reservoir to better accommodate the new floating cover and replace existing corroded miscellaneous metal items (i.e., gratings). Since the reservoir will be out of service modifications to the (2) existing Inlet structures, (4) outlet structures, and Overflow structure within the reservoir will be performed to make the structures more floating cover friendly. The modifications will include reducing the height of vertical concrete walls so structures are lower profile and more flush with reservoir floor and side slopes, eliminate need for pipe grillages or reduced grillage height, minor concrete repairs where necessary, and replace existing corroded gratings.

April 20, 2021, Item #5January 15, 2020 Ms. Melody Rocco, PE City Engineer City of Poway, Development Services Department 13325 Civic Center Dr Poway, CA 92064 Re: Poway Water Treatment Plant -Clearwell Upgrade Project Amendment No. 2: Evaluation of Clearwell Alternatives Dear Melody: Per your request, we are pleased to submit this proposal to provide an evaluation of alternatives for the existing 10 MG Clearwell at the Lester J. Berglund Water Treatment Plant (WTP). We understand these services will be executed as an amendment to IEC's existing contract for the Clearwell Upgrade Project (dated May 15, 2019). Our proposed scope of services is aimed at comparing three options for the Clearwell at a conceptual level: retain the existing reservoir with new liner and floating cover or replace the existing reservoir with dual tanks, either welded steel or pre-stressed concrete. The comparison assumes that the operational high water level in the existing reservoir is preserved to avoid hydraulic impacts to the WTP. Information required from the City is as follows: • Billing records from City for water sales and updated GIS data for meters. Data shall encompass past three years of billing data and shall, at a minimum, contain the monthly water consumption and meter ID. The meter ID shall be a unique value that links to a GIS meter element. If there is no unique meter ID, then the meter billing data and GIS should both contain either a parcel number or address. • Data on Clearwell operations under existing minimum and maximum demand conditions. A minimum of one week of data is required from each period from the City showing WTP production rate, Clearwell level, and Clearwell outflow rate on the same time scale (in Excel spreadsheet format with data at 10 min intervals). The specific tasks to be performed are as follows: 1. Demand and Hydraulic Model Update • Obtain and review billing data from City. • Update existing system demands in the City's hydraulic distribution system model. Perform analysis of the billing data to determine the three-year average for each 14 91i 1B1ni I on Srre '· f>owoy, C liforni 92064 T 858 413 2400 F 858.4 I 3.2440 WWW iecorporolion.com
April 20, 2021, Item #5account. Link the billing data and GIS meters with average annual demands (AAD). Use the functions within the model to load the system demands by pressure zone where possible. Document the final existing AAD in the model. • Develop estimate for ultimate system demands by scaling from the updated existing demands using previous Master Plan (2009) estimates. 2. Clearwell Volume • Review WTP data and analyze Clearwell operation under existing minimum and maximum demand conditions using a mass balance approach. Develop a preliminary volume for the replacement Clearwell (dual tanks). • Conduct an analysis using the updated hydraulic distribution system model to validate the proposed Clearwell volume and WTP capacity in terms of existing demands. Determine impacts, if any, to the WTP and distribution system operations using the proposed Clearwell volume and identify volume adjustments if needed. • Summarize the findings from Tasks 1 and 2 in a brief technical memorandum (TM) and submit to the City in PDF format. • Prepare for and meet with WTP Operation staff to discuss plant and Clearwell operations. The goal of this meeting will be to reach consensus on the volume to be used for evaluating alternative Clearwell structures. 3. Compare Clearwell Structure Alternatives • Evaluate three options based on the parameters from Task 1: o Currently planned floating cover and liner replacement (including potential need for modifications to overflow structure) o Dual welded steel tanks o Dual prestressed concrete tanks • For each option, estimate concept-level construction cost that includes general grading, tank construction, piping modifications, and floating cover/liner replacement (using information from the recent project preliminary design). The estimates will assume existing subsurface conditions can provide satisfactory support for any of the alternatives without special foundation requirements. • Compare the options in terms of capital and life-cycle costs considering estimated future maintenance intervals and operational elements. 4. Report • Summarize the results of the preceding tasks in a report that includes a plan view graphic for each alternative. Submit draft of report in PDF format for City review. • Respond to City comments and submit a final report in PDF format. 47 of 151
April 20, 2021, Item #5Following receipt of the City's notice to proceed and the billing records and operational information described in Task 1, the Clearwell Volume TM will be submitted within three weeks. The Draft Report will be submitted within three weeks of the meeting to discuss the TM. The fee for these services is presented in the attached table and will be invoiced monthly on a time and materials basis. Please advise if this prompts any questions. Thank you for the opportunity to be of service to the City of Poway. Sincerely, /4o .~ Anders . Egense, PE Senior Project Manager Enclosure 48 of 151

April 20, 2021, Item #5Amendment No. 3 Scope of Services for Clearwell Upgrade Project: Bypass Pipeline BACKGROUND The City of Poway (City) proposes to construct a 36" diameter pipeline to allow the conveyance of treated water from the Lester J. Berglund Water Treatment Plant (WTP) around the Clearwell and directly to the distribution system. The major elements of this Project are: • • • • • • Approximately 770 feet of 36" welded steel pipeline with tee connections to the existing 42" effluent pipeline downstream of the WTP (east connection) and to the existing 36" discharge pipe from the Clearwell (west connection). The east connection is along the exposed effluent pipe located in the pipe gallery where three valves will be located at a new tee. Structural modifications to the concrete pipe gallery and pipe supports will be required. The western connection will be west of the Clearwell in the parking area of the Operations Yard. A cast-in-place concrete vault approximately 15 ft x 15 ft and 8 ft deep will house two valves at the new tee. The vault will have a removable top and access hatch designed for H20 loading. All the valves will be manually operated and will not be connected to SCADA. Valve stem extensions will provide for valve operation from above the vaults. The bypass pipe will include a tee outlet with blind flange in Lake Poway Rd and will be designed to allow flow in both directions in anticipation of the potential future delivery of treated water from the Water Authority. To accelerate the project, the City will pre-procure the large valves via one separate bid package and include the valves as owner-furnished materials in the pipe construction bid package. The City engaged Infrastructure Engineering Corporation (Consultant) via the Clearwell Upgrade Project Agreement dated May 15, 2019 (Agreement) and approved Amendment No. 1 for expanded services dated November 22, 2019. Per City direction, this Amendment No. 2 provides for revised services focused on the Bypass Pipeline. The scope of services under the Agreement and Amendment No. 1 are superseded by the services described in this Amendment No. 2 until such time as the City and Consultant mutually agree to further modify the original Agreement. Described below are the specific Amendment No. 2 tasks to be performed by the Consultant. All tasks are directed to Consultant unless otherwise noted. SCOPE OF SERVICES 1.0 Project Kick-Off and Data Compilation In preparation for the project, review City-provided as-built plans pertinent to the Project.

April 20, 2021, Item #5Amendment No. 4 Scope of Services for Clearwell Upgrade Project Design for Bypass Tank BACKGROUND Based on the results of previous evaluations, the City of Poway (City) proposes to construct a 2.5 MG tank as part of a bypass system that will allow the conveyance of treated water from the Lester J. Berglund Water Treatment Plant (WTP) around the existing Clearwell and directly to the distribution system. The major elements of this Project are assumed to be as follows: • A 2.5 MG tank to be located on a vacant site north of Lake Poway Rd opposite the existing Clearwell. The tank will be connected on the inlet and outlet sides to the Bypass Pipeline (a proposed pipeline being designed under a separate authorization). • The tank will be a permanent, circular pre-stressed concrete tank with column supported concrete roof that is partially buried with high water and floor levels that match the existing Clearwell. • Tank appurtenances: main and secondary entrance hatches with interior stairway and ladder, vents, overflow pipeline with air-gap connection to storm drain, and underdrain leak detection piping. • A valve vault located adjacent to the tank that is approximately 10 ft x 10 ft x 20 ft deep. • Manually operated valves. • Site improvements: paved access road, fencing, landscaping, temporary irrigation for plant establishment, storm drain hydromodification and bio-retention. • Basic 120v power supply at the tank entrance hatch tank. • Instrumentation comprised of sonic water level measurement with signal conveyed to WTP control building. • The construction plans and specifications for the tank will be merged with the documents for the bypass pipeline and issued for bidding and construction as one combined project. The City engaged Infrastructure Engineering Corporation (Consultant) via the Clearwell Upgrade Project Agreement dated May 15, 2019 (Agreement) and has also approved amendments for additional services including the design for the Bypass Pipeline (Amendment No. 3). Described below are the specific tasks to be performed by the Consultant related to the Bypass Tank Project. All tasks are directed to Consultant unless otherwise noted. SCOPE OF SERVICES 1.0 Project Kick-Off and Data Compilation Prepare for and lead one kick-off meeting with City's project team. Lead consultant team members will attend. Prepare agenda and meeting notes. In conjunction with the meeting, conduct a tank site visit to observe existing conditions. 2.0 Surveying Using the aerial flight and control information previously obtained for the Bypass Pipeline, prepare topographic base map for the tank site suitable for 1" = 20 ft scale. Conduct field survey to locate surface 1 of 7 7-8-20 60 of 151
April 20, 2021, Item #5features and other pertinent details on the tank site. Merge site and pipe mapping. Tie-in pothole locations to mapping via field survey. 3.0 Utility Research 3.1 Utility Records Research Review utility information previously obtained for the Bypass Pipeline along the Lake Poway Road corridor to identify existing utilities on the site and in the adjacent roadway. 3.2 Potholing Consultants's subconsultant {AirX) will perform potholing along the pipe alignment for up to 10 potholes in addition to, and at the same time as, the potholes identified in Amendment No. 3 Bypass Pipeline scope. The pothole information will be included on the plans, and the plans will be submitted to the respective utility owner for conflict checking at the 60% design stage. Potholes in paved areas will be patched with perma-patch type material. 4.0 Geotechnical Investigation Prepare a plan with figure {PDF) showing the location of proposed borings, seismic lines, and vehicle access routes for use by the City in obtaining environmental clearance for the investigation. The plan will include information regarding type and size of drilling equipment and support vehicles, number of personnel, and the approximate limits of the proposed work area for the geotechnical exploration. Consultant's subconsultant {Ninyo & Moore) will perform an investigation to evaluate the geotechnical and geologic conditions at the tank site. The specific tasks to be performed are: 61 of 151 • Review available literature pertinent to the geotechnical conditions at the site. • Mark the proposed boring locations for clearance by Underground Service Alert. Obtain a no-fee Right of Way Permit from the City. • Obtain a boring permit from the County of San Diego Department of Environmental Health {DEH). • Drill, log, and sample two {2) rock core borings within the proposed footprint of the tank. The borings will be drilled to a depth of approximately 60 ft. The upper portions of each boring will be drilled using hollow stem auger equipment until rock is encountered, where coring equipment would then be used. Rock cores will be collected, stored in rock core boxes, and logged by a geologist. Borings will be backfilled per DEH requirements. Excess soil/rock cuttings and drilling fluid from the borings will be containerized and disposed of offsite. • Perform two (2) seismic refraction survey lines within the proposed tank area, each approximately 200 ft in length. The seismic refraction lines will be performed to evaluate the general rippability of the subsurface materials at the tank location. • Perform laboratory tests consisting of in situ moisture content and density, grain-size distribution, Atterberg limits, R-value, and corrosivity. • Assess potential geologic hazards that may affect site development such as settlement, liquefaction, collapse, and earthquake shaking, and develop recommendations for site preparation and earthwork, general stability of proposed cut slopes, excavations, grading and excavation characteristics of the on-site materials, including anticipated difficult excavation, caving potential, and oversize material handling, fill material and compaction requirements, including suitability of the on-site soils for use as structural fill and bedding material, suitable foundation types for the 2 ofl 7-8-20
April 20, 2021, Item #5proposed tank structure, allowable bearing capacities, friction coefficient, allowable passive pressures, and corrosivity of the on-site soil in respect to concrete. • Prepare a geotechnical report presenting the findings, conclusions, and recommendations. 5.0 Preliminary Design 5.1 Bypass Pipeline Tank Alternatives Evaluation Evaluate and compare a circular versus a rectangular concrete tank configuration to determine the most cost effective layout. This will be based on a preliminary evaluation of the construction grading, general operational features, and a concept-level comparative opinion of estimated construction cost. Summarize the results and recommendations in a technical memorandum (with 11 x 17 figures) and submit to City in PDF format. Meet once with City to discuss and receive comments and reach concurrence on the preferred tank configuration. Incorporate the results of the evaluation in the Preliminary Design Report (Task 5.2). 5.2 Preliminary Design Report The Preliminary Design Report (PDR) will be based on the results of the tank alternatives evaluation and will incorporate the Bypass Pipeline PDR results so as to combine the tank and pipeline into one project. Prepare and submit a Draft PDR (in PDF format with selected 30% drawings presented as llx17 figures) that addresses the following for the Bypass Tank and Pipeline: • Site plan with construction and finish grading • Typical section for tank • Bypass pipeline horizontal alignment • Inlet and outlet valve location • Overflow with air-gap connection to storm drain • Tank drain • Underdrain system • Permanent stormwater facilities • Access road • Fencing The PDR will include a discussion of: • Options for staging and temporary soil stockpiling • Access hatches and stairways • Landscaping • Power and SCADA • Preliminary opinion of construction cost estimate. Meet once with City staff to discuss/coordinate design elements. Meet once with the City to review the Draft PDR and address questions.

Hilts Consulting Group (HCG) was retained by IEC to provide professio al engineering services for the floating cover portions of he project, as d~ ailed in the origi al agreement. As part of the original scope or work and as a result of the existing HOPE liner material investigations there is sufficient evidence to suggest the existing liner material may be at or near the end of its useful life and highly doubtful the existing liner is adequate to expect an additional 20 years or more of service life to coincide with the anticipated life of he proposed replacement floating cover. To provide the City additional information to assess an alternate project implementation strategy, HCG proposes material testing be performed o the existing Hypalon floati g cover material. The purpose of the ma erial testi g is o estimate the additional remaining life for the existing floating cover material and in turn provide the City additio al time to plan and implement the necessary measures to accommodate a clearwell Hner and floating cover replacement. Scope of Worlc HCG will provide coordination .and collaboration with IEC and 3rd party geomembrane material testing laboratory.

Berglund Water T eatment Plant (WTP). We understand these se ices wlll be executed as an amendment to IEC's existing contract for the Clearwell Upgrade Project (dated May 15, 2019). Our proposed sc.ope of services is aimed at comparing three options for the Clearwell at a conceptual level: retain the existing reservoir with new liner and floating cover or replace the existing reservoir with dual tanks, either welded steel or pre~stressed concrete. The comparison assumes that the operational high water level in the existing reservoir is preserved to avoid hydra lie impacts to the WTP. Information required from the City is as follows: • Bilfin records from City for water sales and updated GlS data for meters. Data ~hall encompass past three years of billing data and shall, at a minimum, contain the monthly water consumption and meter ID. The meter IDs all be a unique value that links to a GIS meter element. If there is o unique meter ID, then the meter billing data and GS .should both contain either a parcel number or address. • Da a on Clearwell operations under existing minimum and maximum demand conditions, A minimum of one week of data is required from each period from the City showing WTP production rate, Clearwell level and Clearwell outflow rate or the same time scale (in Excel spreadsheet format wi h data at O min intervals). The specific tasks to be performed are s follows: 1. Demand and Hydraulic Model Update • Obtain and review billing data from City. • Update existing system demands in the City s hydraulic distribution systern odel.

Document the final e isting AAD in t e mode . • Develop estimate for ultimate system demands by sea ing fro the updated exis in demands using previous Mas ·er Pia (2009) estimates. 2. Clearwell Volume • Review WTP data and analyze ClearweU operation under existi· g minimum a d maxi um demand conditions sing a mass balance approach. Develop a preliminary volume for the replacement Clearwell (dual tanks). • Conduct an .anal~is using the updated hydraulic distrlbutio system model to valida e the proposed Clearwell volume and WTP capacity in terms of existing demands. Determine impacts, if any; to the WTP and distribution system operations using tt e proposed Cf arwell volu, e and identify volume adjustments ·f needed. • Summa ize the findings fr.om Tasks 1 and 2 in a brief tech ical emorandum (TM) and submit to the City in PDF format. • Prepare for and mee wi h WTP Operation staff to discuss plant and Clearwell operations. The goal o this meefng will be to reach coilsens son the volume o be used for evaluating afternative Cl-earwell s ructures. 3. Compare Clearwe I Structure Alter.natives • Evaluate three options based on t 1e parameters from Task Currently planned floating cover a d liner replacement (includi g pote tial need for modifications to overflow str c ure} o Dual w lded ste f tanks c Dual prestressed concrete tanks • For each option, esti · ate concept-eve·1 construction cost that incl des general grading, tank construction, piping modifications and floating cover/liner replacement ( sing information from the recent project preliminary design). The estimates wtll assume existing subsurface conditions can provide satis actory support-for-any ofthe alterna ive~ without specia·I foundation requirements. • Compare the options in terms of capital an life-cycle costs considering estimated fu ure maintenance intervals and operational elements 4.

Ca liforn ra Dear Mr. Egense: At your reques( we are pleased to submit this proposal for an additional geotechnical evaluation for the City of Poway Public Works Departments Poway Bypass Project in Poway California. The project is located at the City of Poway Public Works Department's Lester J. Berglund Water Treatment Plant on Lake Poway Road. Our offices previously performed an evaluation fort e projec and the results of our evaluation were presented in our report dated March 31, 2020. We understand that the design and location of the project has been modified since the time of our evaluation and that additional subsurface information is needed. Based on the conceptual plan provided to us dated November 9 2020 we understand the project will include a temporary above-ground tank to the east of the water treatment plant in the baltfield area,. temporary pump station located southeast of the Clearwell, and a new permanen buried 36-inch diameter gravity flow pipeline. The pipeline is an icipated to be at depths up to 15 feet below the ground surface. Based on our previous borings in the area, we anticipate encounterng fill, old all _vium, and granitic rock. Based on provided plans and information (Poway Municipal Wa er District, 964). a fill slopes up to 20 feet in height is present to the west of the Clearwell, and fill materials wit depths up to 12 feet are anticipated to the east of the Clearwell. Our evaluation will u ilize subsurface exploration data obtained during our previous evaluation at the si e to supplement our proposed subsurface exploratio . 5710 R;ffin Road I S n Diego, Califor ia 92123 I p 858 576 10 I ww v.ninyoan rnoore.com 130 of 151
April 20, 2021, Item #5SCOPE OF SERVICES Based on our understa ding of the project, we propose the following scope of services: • Reviewing background information including topograp ic maps, geologic . ap , fautt maps1 and aerial photographs pertinent o the project. • Reviewing available geotechnical reports or plans. • Obtaining a Right-of-Way permit from the Ci1y of Poway for the project site. We have assumed that any City permit fees associated with this project will be waived. • Performing a geologic reconnaissance of the site and mark-out of the proposed boring locations by professionals from our office. Underground Service Alert (USA) will be contacted for utility clearance. • Performing a subsurface exploration consisting of drilling logging and sampling th ee exploratory borings in the area of the proposed pipel'ne alignment and tank. The borings will be advanced to depths of approximately 15 to 20 fee below grade {or auger refusal) with a track-mounted, limited access drill rig equipped with hollow stem augers. Two borings will be loca ed in the vicinity of the proposed tank in the existing balJfield area and one boring will be in the a ea of the proposed buried pipeline. Bulk and in-place samples of t e encountered soils will be callee ed and transported to our i 1 .. house geotechnical laboratory for testing. Borings will be backfilled with DEH approved materials. Excess soil cuttings gene ated from our borings will be spread at a designa ed location onsite. • An additional exploratory boring will be adva ced using manual equipment (i.e. hand auger) within the tank footprint. This bodng will be advanced to a depth of 5 feet (or refusal). • Performing geotechnical laboratory testing on represen alive soil samples. • Compiling and performing an engineering analysis of the data obtained. • Preparing a geotechnical evaluation report that will include our findings, conclusions, and recommendations rela ive to design and construe •ion oft e project. ASSUMPTIONS ln preparing this proposal we have made the following assumpUons: • The project is subject to prevailing wage requirements under etermination year 2019~ 1D .. • Upon awarding of the project, the cflent win p ovide in writing the Department o Industrial Relations (DIR) project number. • Permission for site access to our personnel and vehicles will be granted, Ninyo & foore i Cil oJ P ,iay Pu I c 'o<k' ep rtm 1.

April 20, 2021, Item #5• Our field operations can be performed during regular work hours, F iday, 8:00 a.m. to 5:00 p.m. -The---si e-i -tlr-iv .cees ible-foP--2-~lfl E>llRt F' ig. • Right-of~Way permits ill be required for our proposed subsurface exploration but traffic control will not be requi ed since no work is wi hin the public Right-of-Way. Because our work will be performed for the City of Poway, fees associated with the right-of-ay permits will be waived. If traffic control is required a cost estimate fort ese services will be provided upon your request. • Our subsurface exploration will not require drilling permits from the County of San Diego Department of Environmental Healt (DEH). • We understand that borings at the ballfield will be performed in the dirt infield, outside of grass areas. We will utilize plywood to avoid damaging the balJfield while maneuvering the rmited access drill rig to the planned boring locations. • Excess soil cuttings from our borings will be spread thin at a designated onsite location. If excess soil needs to be disposed of off-site, there will be an additional fee. • Borings will be backfi led with DEH approved materials and borings within paved areas will be capped w·th Perma Patch at the surface. • If patching of paved areas with hot mix asphal is required by the City of Poway, additional fees w·u be required for paving and t affic control. • Environ ner tal sampling and testi 19 of the subsurface soils or ground water, and environmental assessment are not included within the scope of this proposal. A cost estimate for these services will be provided upon your request. FEE ESTIMATE Our fee to perform the services outlined above will be invoiced on a time-and-materials basis and is estimated to be $25,400 (Twenty-Five Thousand Four Hundred Dollars). The estimated fees are based on the scope of services presented above and our understanding of the existing conditions and the proposed improvements. Additional services, beyond those described herein, if requested, will be performed on a time-and-materials basis .. SCHEDULING We are prepared to begin our services immediately upon receiving your written a thorization to proceed. The permitting of the fieldwork may take two to four weeks and drilling activities a e anticipated to take one working day. Our report will be finished approximately four weeks following performance of our fieldwork. N1nyo & • ore I 132 of 151 ·)'Public·~ r~, Dep~rtmenl o sy. California I 897B 04 I Oem~ber 2, 202 ------

In response to the City's request to expedite this project, IEC is submitting this revised proposal. The new approach includes preparation of two new Standard Operation Procedures (SOPs): one to describe the start-up of the bypass facilities and one to describe the operation of said facilities; review of the SOPs by the City for comment; incorporation of City comments into the SOPs, and submittal of draft final SOPs to the State Regional Water Quality Control Board -Division of Drinking Water (DOW). The draft final SOPs would take the place of Modified Operational Plan, but would place critical information into DOW hands for review. After a review meeting with DOW, the SOPs will be finalized and incorporated into the City's existing 2019 Operational Plan. After one more review by the City, the final Modified Operational Plan will be delivered to the City for submission to DOW. This new approach allows the City to deliver the critical information about the Temporary Bypass Plan to the DOW ln a timelier fashion, while keeping the final deliverable for the project the same. We are attaching a revised Exhibit A and Fee as well as the original proposal. We will start on this work as soon as we receive a Notice to Proceed from the City. Please feel free to call me with any comments or questions you may have. I may be reached at 858-842-6978. Thank you for the opportunity to continue to assist the City will this important project.

April 20, 2021, Item #5EXHIBIT A-SCOPE OF WORK AND FEE FOR START-UP AND OPERATIONS PLAN FOR TEMPORARY CLEARWELL BYPASS SYSTEM AT POWAY WATER TREATMENT PLANT .. REVISED INTRODUCTION The City of Poway (City) operates the Lester J. Berglund Water Treatment Plant (WTP) to produce and deliver drinking water to City customers. The WTP uses rapid mixing, coagulation, sedimentation, filtration, and disinfection to treat the water. After the filtration process, treated water flows through a 42-inch (42'') filter effluent pipe to a 10 million gallon (MG) Clearwell where it is stored before being conveyed to the distribution system. The City has concluded, based on previous studies, that the existing Cleaiwell is in need of replacement. The new Clearwell is slated to be built within the footprint of the existing Clearwell. In order to facilitate construction of the new Clearwell, a Temporary Bypass System will be constructed and placed into operation for the duration of the demolition and construction of the new Clearwell. Via separate contract with the City, Infrastructure Engineering Corporation (IEC) is currently preparing design documents for the Temporary Cleaiwell Bypass System. These facilities will consist of the following: Bypass Tank -A 2.0 MG temporary bolted steel tank located just east of the WTP on a baseball field in Lake Poway Park. • Bypass Pump Station -A temporary pump station to pump treated water from the 42" WTP effluent line to the temporary tank located at an elevation about 50 feet higher than the effluent line. • Bypass Pipeline -A 36" permanent pipeline that conveys water from the 42" WTP effluent line to the existing distribution piping located in the Operations Yard. This pipeline also serves as the suction line for the Pump Station. • Tank Inflow/Outflow Pipe -A 24' pipeline that conveys discharge from the Pump Station to the Bypass Tank and from the Tank back to the Pressure Control System. • Pressure Control System -A system of pressure reducing valves that will control the flow from the Bypass Tank and break head down to the 865 Zone. SCOPE OF SERVICES The specific tasks to be performed by IEC are as follows: 1 . Conduct a kick off meeting with \h/TP Opemtions staff to obtain input rngarding ourrent and anticipated plant operations. 2. Prepare draft Standard Operating Procedures (SOPs) for the Start-up and Operation of the Temporary Clearwell Bypass System. Submit draft (Word file format) to City for review. The SOP will be set of directions on how to start-up or operate the Temporary Bypass System. The SOP will be a "translation' of the control narrative into narrative procedures. 3. Prepare for and conduct a workshop with City staff to discuss the draft SOPs. 4. Prepare revised SOPs based on input from City for submission to State Water Resources Control Board -Division of Drinking Water (DOW). Submit Fovised SOPs to City (WoFe file format) for one additional round of comments. 5. Prepare for and coordinate a review meeting with DOW Page 1 of 2 140 of 151
