Mr. Greg Kowalski, PE Eastern Municipal Water District 2270 Trumble Road Post Office Box 8300 Perris, CA 92572-8300 RE: Request for Proposals (RFP) – Perris North Groundwater Contamination Prevention and

Remediation Program: Final Design of the Moreno Valley and South Area Facilities and Pre‐Procurement Documents for Overall Program

Dear Mr. Kowalski:

Tetra Tech is pleased to submit our fee proposal to Eastern Municipal Water District (District) for professional engineering services supporting the Final Design of the Perris North Groundwater Contamination Prevention and Remediation Program (Program) for Moreno Valley and South Area Facilities (Project).

Based on the scope of work presented herein, a labor and not-to-exceed fee estimate has been prepared for the project. We have included optional items as requested in the RFP as well as additional items for consideration by the District. The fee has a base cost as well as the cost for the optional items. Labor hours are delineated by task and employee. Compensation is based on a time and materials basis. An hourly fee schedule is provided based on our current billing rates.

The Tetra Tech team consists of Tetra Tech and its subconsultants: Cozad and Fox (survey), Converse Consultants (geotechnical), C Below (utility potholing), RF Yeager (corrosion control) Jensen & Hughes (fire protection) and Behrens & Associates (acoustical analysis). A copy of each of the subconsultant proposals are attached with this fee letter. A 10-percent markup is included in our fee for other direct costs and subconsultants.

Tetra Tech will submit monthly invoices showing a breakdown of hours spent by individual employees for each task, employee hourly rates, total contract amount, amount remaining and percent completion for each task.

SCOPE OF WORK

Tetra Tech reviewed the District’s scope of work presented in the RFP and generally agreed with the tasks and the approach. We acknowledge the scope of work for the sake of brevity and will not repeat the scope in the RFP. Instead, we have provided a summary of the modifications or augmentations to the published scope of work.

Task 1 – Project Management

Tetra Tech will schedule and lead monthly coordination and biweekly progress meetings with District. Tetra Tech will prepare agenda, and meeting minutes for all meetings for the duration of the Project.

Mr. Greg Kowalski, PE June 9, 2020

Task 2 – Data Gathering, Site Reconnaissance, and Analysis

Mapping including property boundaries and right of way, record drawings, and relevant information (aerial, topographic, geologic, environmental, etc.) will be obtained from documents prepared during the preliminary design phase by the District. Tetra Tech will perform a USA request and contact agencies/utility companies identified by that request to obtain record drawings.

Tetra Tech will complete an independent review of all provided reference documents to either confirm the recommendations or suggest alternatives. Alternative recommendations shall be identified and discussed early in the design. Redline comments of the PDR will be provided.

To take advantage of the District’s proactive decision to begin survey work for this project, we have added Cozad and Fox to our team to perform additional survey for the project. Summarized below are the survey tasks that will be performed.

Task 2.1 Survey

1. The surveyor will perform additional research to augment the District provided survey data and review survey records at the County of Riverside in order to provide a basis for the control survey and to tie-in monumentation for street centerlines.

2. We will perform field control survey to recover existing control necessary to search for existing property corners and street monuments and tie the topographic survey to the project alignment.

3. Perform one day of field survey for surface features of utilities and spot elevations to augment the District’s provided topographical survey.

4. Prepare a control survey drawing depicting found monuments and survey control with descriptions.

5. Provide digital topographic mapping augmenting the District’s provided topography.

Deliverable: Tetra Tech will submit electronic AutoCAD files of the augmented topography and a provide a signed and sealed hardcopy by the California Licensed Land Surveyor. Survey notes, control points, level circuits for the project will be submitted in PDF format.

We have coordinated with Converse Consultants to perform the optional Geotechnical work, if it is deemed to be required. The District has proactively moved forward with the geotechnical investigation. Based on our conversations with Converse Consultants we have developed the following scope of work for the optional geotechnical task:

Task 2.2 Geotechnical

1. Drill two (2) additional borings. One at the Perris Well 204 site and the other at the Wells 65/66 Treatment Plant site in Moreno Valley. The borings will be drilled between 25 to 50 feet below existing ground surface or until refusal.

2. We have assumed the borings will be on-site and conducted during normal business hours. We have assumed no traffic control will be required.

3. Updated the geotechnical reports prepared under contract with EMWD and incorporate the information obtained from the 2 additional borings. The report will be signed and sealed by a geotechnical engineer licensed in California.


3 TETRA TECH

4. Review the 90 percent project plan and specifications to verify conformance with the conclusion and

recommendation presented in our geotechnical reports. A letter will be prepared outlining

comments or provide approval of the documents.

Task 2.3 Utility Potholing

For the pothole work, we have made the following assumptions:

1. Ten potholes will be 0 to 5 feet deep and Ten potholes will be between 5 and 10 feet of depth.

2. We have assumed standard traffic control measures including one lane closure with minimal signage

not spanning an intersection. Engineered traffic control plans are not required and that WATCH and

MUTCD Manuals can be used.

3. A standard pothole is 12 in x 12 in, performed to the top of pipe or encasement with sand backfill

and a permanent. 2 x 2'surface cold patch.

Task 2.4 Corrosion Report

We have assumed that the District’s Geotechnical Engineer will obtain soil samples and provide soil chemical analysis that at a minimum includes: pH, sulfate concentration, chloride concentration, and soil box resistivity in the as-received and saturated conditions. We will review the District’s geotechnical report, once it is available, and coordinate with the District is additional information is required to complete the corrosion analysis. Summarized below is our scope of work:

1. Conduct a review for the potential of stray current interference. It is understood that the Project pipeline may cross several other buried metallic utilities that may be cathodically protected. Where needed, we will contact the other pipeline Owners to determine where their cathodic protection systems are located and at what levels their cathodic protection systems are adjusted to. This will help to determine the potential for stray current on the new EMWD pipelines and will assist in determining the type of stray current mitigation should they be required.

2. Conduct a cost analysis to determine the capital and O&M costs for an impressed current cathodic protection system versus a galvanic anode cathodic protection system. The cost analysis will include all costs associated with installations, materials, labor, and required electrical service.

3. Provide a Corrosivity Assessment Report to include all test data, observations, conclusions, and recommendations for corrosion control, materials of construction, coating options, and stray current mitigation (if necessary). Recommendations for corrosion control will be based upon sound corrosion engineering practices, District and AWWA Standards, and the available corrosion control methods and coating options.

Task 4 – Preliminary Design Review and Refinement

For the development of the 30% plans, we have assumed the following sheets:

Well 65 Well 65 Site Plan Well 65 Grading Plan Well 65 Yard Piping Plan (no profiles) Well 65 Mechanical Plan and Section Well 65 Discharge Pipe (horizontal alignment)


4 TETRA TECH

Central Treatment Plant and Well 66 Site Plan Grading Plan Yard Piping Plan (no profiles) Well 66 Mechanical Plan and Section Well 66 Discharge Pipe (horizontal alignment) Pumping Station Mechanical Plan and Sections Pump Station Discharge Pipeline (no profile) Street Cross-Section and Pipeline Connection Detail Generator Plan and Section Pumping Station Structural Elevations Electrical Single Line Diagram P&ID Well 204 and Treatment Plant Well 204 Site Plan Well 204 Grading Plan Well 204 Yard Piping Plan (no profiles) Well 204 Mechanical Plan and Section Well 204 Discharge Pipe (horizontal alignment) Generator Plan and Section Treatment Plant Electrical Single Line Diagram Treatment Plant P&ID

For the noise study we have included the following scope of work items:

1. Perform an ambient sound level survey at 5 locations (Well Site 204, 66, 65 area) to determine existing noise levels within the area. A total of 5 noise measurements of 24-hour duration will document existing sound levels within the area. Type 1 sound level meters will be deployed and programmed to continuously measure and record sound levels until retrieval the following day.

2. Perform a noise impact model for proposed operational equipment at Well Site 204, 66, 65 and associated equipment. Using file data or calculations, each noise model will calculate the noise impact of the proposed equipment at each site taking into account the effects of the site’s topography, groundcover and existing structures at the site and adjacent surroundings. The noise impact modeling will be completed using SoundPLAN software, which utilizes the ISO 9613-2 calculation standard. Predicted noise levels will be assessed against the city of San Jacinto noise standards.

3. If required, noise mitigation recommendations will be provided for each modeling scenario to meet the noise limits. The noise mitigation recommendations will be included in the noise modeling to estimate the expected performance. The results of the modeling and final noise mitigation plan will be outlined in a report.

Two site layouts will be reviewed for the central treatment plant facilities and one site layout each for Wells 65 and 204.


5 TETRA TECH

Task 5.2 Water Quality Sampling/Testing and Task 5.4 Treatability Study (optional tasks)

The PDR provided information on anticipated water quality from researching similar wells north and south of Freeway 60 and east of I-215. These wells are in the general vicinity of new Wells 65, 66 and 204. It appears that there is sufficient existing water quality data on adjacent wells in order to continue with the final design of the treatment facilities. While Tetra Tech included pilot testing in the San Jacinto Water Banking project as an optional task, ultimately the testing was not done due to the costs and logistics of providing temporary pumping to obtain a representative sample to test removal efficiencies using various filter media. GAC and IX are proven technologies for the removal of PCE, perchlorates and nitrates.

Consequently, additional pilot testing and/or bench scale studies do not appear to be warranted compared with the estimated costs. As a result, Tetra Tech has not included costs for these optional tasks in our proposal.

Task 6 – Preparation of Contract Documents (Plans and Specifications)

Tetra Tech has developed an anticipated list of drawings for this project. The fee has been developed based on this assumption. The list of drawings is attached with this letter.

Task 6.1 Electrical Systems and Arc Flash

For the arc flash study we proposed the following scope of work:

1. Perform an electrical system study and arc flash analysis for Wells 204, 65, 66 and treatment plant facilities. The analysis shall be consistent with current electrical codes, standards, and requirements; and shall utilize SKM Systems Analysis Incorporated (skm.com) modeling software. The analysis shall include the following components at a minimum: 1) short circuit analysis, 2) protective device coordination analysis, 3) protective device interrupt rating analysis, and 4) arc flash hazard analysis. The analysis shall also include recommendations for mitigating hazards for Category 2 and above. The analysis shall consider the ultimate configuration of the facility and be engineered to Category 3 (or a lesser category) for purposes of safety, electrical coordination and protection, hazard identification, hazard distance, personal protective equipment (PPE), and standardization. The analysis and appropriate mitigation measures shall be incorporated into the construction contract documents (plans and specifications).

2. Schedule and conduct a workshop to review the results and recommendations of the electrical systems study and arc flash analysis.

3. The analysis shall comply with the applicable IEEE, NEC, NFPA and OHSA codes and standards.

Deliverable: Document the findings, results, and recommendations into a stand-alone report. Provide one (1) electronic copy (searchable pdf) of the draft Electrical System Design, Study and Analysis report for District review. Incorporate District comments and provide three (3) hard copy reports and one (1) electronic copy (searchable pdf) of the final Electrical System Design, Study and Analysis report.


6 TETRA TECH

Task 7 – Pre‐procurement Bid Documents

Tetra Tech will evaluate approaches to procurement of long lead time equipment, such as selection/negotiation, pre‐negotiation, pre‐approval, and pre‐purchase. Tetra Tech will develop a recommended approach that will control costs, ensure quality, and reduce the risks of conflicts and claims during construction, but still meet schedule and maintain grant funding time commitments. Two pre-procurement packages have been included in the scope of work.

Moreno Valley Area – Facilities in this area include 2 groundwater extraction wells (Wells 65 and 66) with an approximate combined flow rate of 2,000 AFY (approximately 620 gpm per well). Each well is to be situated on District owned property south of Ironwood Avenue between Heacock Street and Nita Drive in the City of Moreno Valley, California. In addition, the project will include a centralized treatment facility supplied by Wells 65 and 66. Based on the PDR the treatment facility will consist of single‐use fixed bed ion exchange for perchlorate removal, staggered bed regenerable ion exchange for nitrate removal, and granular activated carbon (GAC) for PCE removal. The facility will also include a finished water pumping station and a clear well. Approximately 800‐feet of 8‐inch pipeline will be required to connect the existing raw water conveyance pipeline from the wells to the treatment facility. Finished water will be conveyed via 12‐inch and 18‐inch pipelines to the District’s local potable water system on Ironwood Avenue. See reference material for the draft PDR for additional details on the Moreno Valley area project.

South Area – Facilities in this area include one groundwater extraction well (Well 204) with an approximate flow rate of 1,000 AFY (approximately 650 gpm) that is situated on District owned property (~2.5 acres) located at 115 East Nance Street in the City of Perris, California. In addition, a wellhead treatment facility consisting of GAC treatment is needed to remove PCE. Approximately 1,300‐feet of 8‐inch pipeline will be required to convey finished water into the District’s potable water system.

Numerous other earth material physical tests can be performed in our geotechnical laboratories, including rock core, soil cement and soil lime mixture tests. Tests not listed can be quoted upon request. This fee schedule is valid through December 31, 2020. Prices are based on the assumption that samples are uncontaminated and do not contain heavy metals, acids, carcinogens and/or volatile organics which can be measured by an organic vapor analyzer or photoionization detector with a concentration greater than 50 parts-per-million (ppm). Quoted testing fees are based on the assumption that no protective clothing will be required to handle samples. If Level D protective clothing will be required during handling of samples (as defined in Federal CFR Part 1910.120), then a 40% increase in fees presented in this schedule will be applied. Level C protective clothing will be a 60% increase in fees. Converse will not handle samples that require either Level B or Level A protection in our geotechnical laboratories. Contaminated samples will be returned to the client. Uncontaminated samples will be disposed of 30 days after presentation of test results. The client must disclose the source of samples. Samples imported from out of state will be incinerated after testing in accordance with requirements of the United States Department of Agriculture. Soil samples obtained within the State of California currently designated quarantine areas will also be incinerated in accordance with the requirement of the State of California, Department of Food and Agriculture, Division of Plant Industry, Pest Exclusion. A $5.00 incineration fee will be added to each sample that is required to be incinerated in accordance with State and Federal law. Test results requiring plots will be presented in a publishable format generated from computer programs. Otherwise, raw test numbers will be presented. A minimum laboratory fee of $50.00 will be charged to present and mail test results. Beyond the standard U.S. Mail delivery, specialized transmittal will be charged at additional cost (e.g., Federal Express, UPS, etc.). Geotechnical testing does not include engineering and/or geologic review and analysis. Typical turnaround for geotechnical laboratory testing is two weeks (or roughly ten working days). To expedite test turnaround to five working days, a 50% increase in the fees in this schedule will be applied. Many geotechnical tests require at least one week to perform in accordance with ASTM or other standard specifications. Fees presented in this schedule for relatively undisturbed direct shear, consolidation or expansion pressure tests are based on the assumption that 2.416-inch inside diameter brass ring samples will be provided to the geotechnical laboratory for testing. Remolded specimens will be compacted in standard 2.5-inch outside diameter brass rings for direct shear, consolidation and expansion pressure tests. All fees presented in this schedule are based on the assumption that the client will deliver samples to our laboratory at no additional cost to Converse. Invoices will be issued monthly and are payable on receipt unless otherwise agreed upon. Interest of 1.5% per month (but not exceeding the maximum allowed by law) will be payable on any amount not paid within thirty days; payment thereafter to be applied first to accrued interest and then to the principle unpaid amount. The Client shall pay any attorneys' fees or other costs incurred in collecting any delinquent amounts.

CONVERSE CONSULTANTS General Conditions –

Right of Entry

Client warrants to Converse that it has full legal right to authorize Converse's entry upon the real property where Converse's services are to be performed ("Site" herein) and upon all property, if any, required for ingress and egress to the Site.

Client authorizes Converse to enter upon the Site and such adjoining property as is necessary to allow Converse to perform its services.

Converse will take reasonable precautions to minimize any damage to the Site; however, Client acknowledges that during the normal course of the performance of Converse's services, some damage to the Site may occur. The correction of any damage to the Site (surface or subterranean) shall be the obligation of the Client.

Information Supplied by Client

Client warrants the accuracy of any information supplied by it to Converse, acknowledges that Converse will not verify the accuracy of such information, and agrees that Converse is entitled to rely upon any such information.

Client shall immediately notify Converse in writing of any data, information or knowledge in the possession of or known to Client relating to conditions existing at the Site and shall provide Converse with the location, size and depth of any and all underground tanks, piping or structures existing upon the Site.

Client shall defend, indemnify and save harmless Converse, its officers, agents and employees from and against any and all claims, costs, suits and damages, including attorneys' fees, arising out of errors, omissions and inaccuracies in documents and information provided to Converse by Client.

Ownership of Data and Documents; Samples

All reports, boring logs, field data, field notes, laboratory test data, calculations, estimates and other documents prepared by Converse shall remain the sole property of Converse.

Client shall have the right to the use of all data, recommendations, proposals, reports, design criteria and similar information provided to it by Converse ("information" herein); provided, however, that the information shall not be used or relied upon by any party other than Client, save and except as may be required by the design and licensing requirements of the project for which the information is provided; further, such use shall be limited to the particular site and project for which the information is provided. To the extent Client utilizes Converse’s information by providing or making the same available to any third party (a) Client agrees to give written notice to any such third party that it may not utilize or rely on any aspect of Converse’s information and (b) Client agrees to defend, indemnify and hold Converse harmless against any and all claims, demands, costs, losses, damages and expenses, including attorneys fees, that may be asserted against or sought from Converse by any such third party.

Client's right to the use of the information is expressly conditioned upon Client's prompt payment to Converse of all sums due under the Client/Converse agreement. In the event of Client's nonpayment or partial payment of said amounts, Client agrees that it shall not use any of the information for any purpose whatsoever and shall return the same to Converse within 2 business days upon demand.

Converse will retain all samples of soil, rock or other materials obtained in the course of performing its services for a period of thirty (30) days. Thereafter, further storage or transfer of samples to Client may be made at Client's expense upon written request from Client to Converse received by Converse prior to the expiration of the 30-day period.

Converse shall retain permanent records relating to the Converse services for a period of five (5) years following submittal of Converse's report, during which period the records will be made available to Client upon reasonable notice given by Client and upon payment to Converse of an amount sufficient to reimburse Converse for its necessary and reasonable expenses in making said records available.

Standard of Care and Professional Responsibility

Client acknowledges that the services to be performed by Converse involve the use of tests, calculations, analyses and procedures which are in a constant state of development, improvement and refinement and that, as such, improvements, changes in methods, and modifications of procedures have been made in the past, are now being made, and are expected to continue to be made in the future.

Further, Client recognizes that, while necessary for investigations, commonly used exploration methods, such as drilling borings or excavating trenches, involve an inherent risk. For example, exploration on a site containing contaminated materials may result in inducing cross-contamination, the prevention of which may not be complete using presently recognized sealing methods.

Client recognizes that the state of practice, including but not limited to the practice relating to contamination or hazardous waste conditions, is changing and evolving and that standards existing at the present time may subsequently change as knowledge increases and the state of the practice continues to improve.

Client recognizes that projects containing contaminated materials may not perform as anticipated by Client, even though Converse's services are performed in accordance with the level of care and skill required of it. Further, certain governmental regulations relating to hazardous waste

sites may purport to require achievement of results which cannot be accomplished in an absolute sense. It is recognized that a satisfactorily designed, constructed and maintained monitoring system may assist in the early detection of environmental changes allowing for early correction of problems. Unless it is specifically included in the scope of services to be performed by Converse, Client understands that Converse shall not perform such monitoring.

The services to be provided by Converse pursuant to the agreement to which these General Conditions are a part shall be provided in accordance with generally accepted professional engineering, environmental, and geologic practice in the area where these services are to be rendered and at the time that services are rendered. Client acknowledges that the present standard in the engineering and environmental professions does not include, and Converse does not extend to Client, a guarantee of perfection of the work contemplated hereby; further, that even in the exercise of normal and reasonable care, errors or omissions may from time to time occur. Except as expressly set forth in these General Conditions, no other warranty, express or implied, is extended by Converse.

Converse shall have no duty to supervise, coordinate or otherwise be involved in the performance of services or work by any third party consultant, contractor or subcontractor.

Where Converse's services involve field observation of grading, filling and compaction (or any of them), it is agreed:

a. That Converse shall in no way be responsible for the manner in which such work is performed by any third party.

b. That in the event Converse is to provide periodic observation, Clientacknowledges that Converse cannot be responsible for any work performed at a time or times when Converse was not performing its observation services.Converse will not provide an opinion concerning the performance of any thirdparty, save and except to the extent that said work was in fact observed andtested by Converse during the course of construction.

c. That where Converse's services include continuous observation, Client agreesnot to allow grading, filling or compaction to be performed at any time or timeswhen Converse is not physically present upon the Site and shall restrict theamount and extent of such grading, filling and compaction to that which can be properly observed by Converse personnel present on the Site.

d. That in the event Converse is to conduct test borings for Client, Clientacknowledges that the accuracy of said test borings relates only to the specificlocation in which the boring itself was performed and that the nature of manysites is such that differing subsurface soil characteristics can be experiencedwithin a small distance. As such, Client acknowledges that greater accuracy isobtained when the number of test borings is increased.

Technical Limitations

Client acknowledges and agrees that: (1) it is unreasonable to expect Converse to be able to completely evaluate subsurface conditions, even after the most comprehensive exploratory program; (2) site conditions change frequently due to the passage of time, human activities, and climatic conditions and uncertainties are therefore inherent in the nature of Converse’s services and impossible to avoid; (3) the identification of geotechnical and environmental conditions and the prediction of future or concealed conditions is an inexact scientific endeavor; (4) the state of the art of geotechnical and environmental practice is such that Converse cannot guarantee that its recommendations will prove adequate on this project and the Client assumes the risk of any such failure, except as otherwise provided in these General Conditions and that (5) these General Conditions contains specific LIMITATIONS OF LIABILITY.

Indemnity of Client and Limitation of Liability

Converse shall indemnify Client, its officers, directors, agents or employees from any claim, demand or liability arising from personal injury or property loss or damage caused by the sole negligence or willful misconduct of Converse.

Anything to the contrary in the agreement to which these General Conditions are attached or in these General Conditions notwithstanding, Converse's liability shall be limited to the lesser of the fees charged to Client by Converse for the services performed for Client, or the sum of fifty thousand dollars. Client may, at its option, increase the maximum amount for which Converse shall be liable by payment of an additional fee. For the maximum liability sum of one hundred thousand dollars, the additional amount to be paid shall be four percent of the total Converse fee charged hereunder; for the maximum liability sum of one million dollars, the additional amount to be paid shall be five percent of the total Converse fees charged hereunder Client acknowledges and agrees that its recovery, if any, shall be satisfied, in the first instance, from the proceeds of Converse’s insurance, and to the extent of any deficiency in the available insurance proceeds, then and only then, by Converse.

Client acknowledges that Converse has agreed to charge Client a reduced fee for services in exchange for the above limitation of liability and that said reduction in fees is consideration for said limitation.

Client shall defend and save harmless Converse, its officers, directors, agents and employees from all liability, claims and demands, including expenses of suit and

Converse Consultants GC99-1

reasonable attorneys' fees arising from personal injuries, including disease and death, property loss or damage, injury to others (including personnel of Client, Converse or subcontractors performing work hereunder), and air or ground pollution or environmental impairment arising out of or in any manner connected with or related to the performance of Converse's services, except where there is a judicial determination that such injury, loss or damage shall have been caused by the sole negligence or willful misconduct of Converse. Client acknowledges that Converse has charged Client a reduced fee for services to be performed by it in exchange for this hold harmless and that the reduction in fees is consideration for said hold harmless provision.

Converse will not be liable for consequential damages of any kind, nature or description.

Hazardous Waste, Pollution and Health Hazard Projects ("Hazardous Projects" Herein)

Prior to the commencement of services by Converse on any hazardous project, Client agrees to advise Converse in writing of any known hazardous waste or materials existing on or near the Site or if any of said services are to be performed in an area where dust, fumes, gas, noise, vibrations or other particulate or nonparticulate matter is in the atmosphere where it raises a potential or possible health hazard or nuisance to anyone working within the area.

Anything in these General Conditions notwithstanding, Client shall indemnify and hold Converse, its officers, directors, agents, servants and employees, harmless from any claim, demand or action brought by any party whomsoever, including employees of Converse which claim, demand or action is based upon injury or damage caused or alleged to have been caused by hazardous wastes or hazardous materials whether or not such waste or materials were known to exist prior to the commencement of services.

Client agrees to be responsible for the removal and disposal of any hazardous waste uncovered as a result of the site investigation, including drill cuttings, unless specifically included within the scope of work

It is agreed that the discovery of unanticipated hazardous materials constitutes a changed condition mandating an immediate renegotiation of the scope of services or termination of services. Converse will at all times endeavor to perform in a faithful and trustworthy manner. Client understands that Client or Converse may be required by local and/or state and/or federal statute to report the discovery of hazardous materials to a government agency. Client also understands that Converse may be required by local and/or state and/or federal statute to report the discovery of hazardous materials to a government agency, and that Converse, when practical, will do so only after notifying Client. In the event Converse discovers hazardous material that we believe poses an immediate threat to public health and safety, Converse will use its best judgment to notify appropriate emergency personnel for immediate containment. Client agrees to take no action of any kind against Converse when Converse makes a good-faith effort to fulfill its obligations.

Client's Responsibilities

Client shall immediately provide Converse with full information in writing as to Client's requirements for the services to be provided by Converse and shall designate in writing within five (5) days of the effective date of the agreement to which these General Conditions are a part, a representative to act on Client's behalf in conjunction with the services to be provided hereunder. Client shall promptly review all documents, reports, data and recommendations submitted by Converse and shall communicate with Converse concerning such reviews for the purpose of avoiding delay in the performance of the services to be rendered by Converse.

Client shall notify any third party who may perform on the Site of the standard of care being undertaken by Converse pursuant hereto and of the limitations of liability contained herein. Client shall require as a condition to the performance of any such third party a like indemnity and limitation of liability on their part against Converse.

Confidentiality

Converse shall hold all information provided to it by Client and the results of the work performed by it confidential and shall not disclose the same to any third party except where required by Governmental regulatory agencies or as otherwise required by law.

Disputes

Converse shall have the right to bring a legal action in a state or federal court against Client for any sums due or alleged to be due to it or for services rendered. Except for this right, Converse and Client agree that as an express condition to the right of either party to bring a legal action against the other, they shall first submit any dispute to mediation by a neutral person acceptable to both parties.

Each party shall bear its own attorneys' fees, costs and other expenses, except that each party shall be responsible and pay for one-half of the costs and expenses of the mediator. In the event that legal action is required, the prevailing party shall be entitled to recover all of its costs incurred in connection therewith including, without limitation, staff time, court costs, attorneys' fees, consultant and expert witness fees and any other related expenses. In this regard, in order to make the prevailing party whole, the parties acknowledge and agree that the prevailing party shall be entitled to recover all of its costs incurred in connection with the legal action and shall not be limited to “reasonable attorneys fees” as defined in any statute or rule of court.

The obligations, responsibilities, warranties and liabilities of the parties shall be solely those expressly set forth herein. Remedies and limitations of liability shall apply regardless of whether an action is brought in contract, or is based on either party’s negligence, or another theory of law. All of the rights, remedies, obligations, terms, conditions and limitations of liability stated herein shall extend collectively to and be binding upon the parties’ partners, joint ventures, licensors, successors, assigns, insurers, and affiliates. Client and Converse agree that any legal action with respect to the services to be performed under these General Conditions shall be brought against the parties, and not against individual officers, employees or former employees of the parties. All legal actions by either party against the other for breach of these General Conditions or for the failure to perform in accordance with the

applicable standard of care, however framed, that are essentially based upon such breach or failure shall be barred two (2) years from the time claimant knew or should have known of its right to make a claim, but, in any event, not later than four (4) years from substantial completion of Converse’s services.

Jobsite Safety

Converse shall be responsible for its activity and that of its employees on the Site. This shall not be construed to relieve the Client, its general contractor or any subcontractor of their obligation to maintain a safe jobsite.

Neither the professional activities nor the presence of Converse or its employees and subcontractors shall be understood to control the operations of others, nor shall it be construed to be an acceptance of the responsibility for jobsite safety.

Converse will not direct, supervise or lay out the work of the Client, contractor, or any subcontractors. Converse's services will not include a review or evaluation of the adequacy of the contractor's safety measures on or near the Site.

Schedules

Unless otherwise specified in the agreement, Converse shall be obligated to perform within a reasonable period of time. Converse shall not be responsible for delays in the completion of its services created by reason of any unforeseeable cause or causes beyond the control and/or without the fault or negligence of Converse, including but not restricted to acts of God or the public enemy, acts of the Government of the United States or of the several states, or any foreign country, or any of them acting in their sovereign capacity, acts of other contractors with Client, fire, floods, epidemics, riots, quarantine restrictions, strikes, civil insurrections, freight embargoes, and unusually severe weather.

Should completion of any portion of the services to be rendered by Converse be delayed beyond the estimated date of completion for any reason which is beyond the control of or without default or negligence of Converse, then and in that event Client and Converse shall mutually agree on the terms and conditions upon which the services may be continued or terminated.

Invoices

Converse shall submit monthly progress invoices to Client, and a final bill shall be submitted upon completion of the services. Within thirty (30) days after receipt of an invoice, Client shall pay the full amount of the invoice. If Client objects to all or any portion of any invoice, it shall so notify Converse of the same within fifteen (15) days from the date of receipt of said invoice and shall pay that portion of the invoice not in dispute, and the parties shall immediately make every effort to settle the disputed portion of the invoice.

If Client fails to make payment within thirty (30) days after receipt of an invoice, then Client shall pay an additional monthly service charge of one and one-half percent (1½ %) on all such amounts outstanding. The additional charge shall not apply to any disputed portion of any invoice resolved in favor of Client. In the event Client fails to pay any undisputed amount to Converse when due, Converse may immediately cease work until said payment together with a service charge at the rate of 1½ % per month, as specified above, from the due date has been received. Further, Converse may, at its sole option and discretion, refuse to perform any further work irrespective of payment from Client.

In the event that all or any portion of the 1½ % service charge provided for herein is deemed to be an interest charge, then and in that event said interest charge shall be limited to the maximum amount legally allowed by law.

Client acknowledges Converse’s fee schedules are revised annually and agrees that the fee schedule in effect at the time the services are performed shall apply to such services.

Insurance

Converse represents that it now carries, and will continue to carry during the term of the contract to which these General Conditions are a part, Workers Compensation insurance and that, if requested, Converse shall provide to Client certificates as evidence of the aforementioned insurance.

Assignments

Client shall not assign this contract or any portion thereof to any other person or entity without the express written consent of Converse. Nothing contained in this contract or any part thereof shall be construed to create a right in any third party whomsoever, and nothing herein shall inure to the benefit of any third party.

Severability

If any provision of these General Conditions is finally determined to be contrary to, prohibited by, or invalid under applicable laws or regulations, such provision will be renegotiated so as to give effect to the intent of the parties to the maximum possible extent. Such determination and renegotiation shall not affect of invalidate the remaining provisions or these General Conditions.

Governing Law

These General Conditions shall be governed by and construed under the laws of the State of California.

Scope of Work \s3\Original Scope of Work

C Below will perform (10) potholes as indicated in the client provided potholing exhibit (to be provided prior to field work).

A standard pothole is 12 in x 12 in, performed to the top of pipe or encasement with sand backfill and a permanent surface patch.

Additional costs: Potholes outside of our standard will be billed based on actual depth or conditions. Limitations on work hours may cause additional mobilization or traffic control charges. Permitting fees will be adjusted to actual costs.

If C Below is not hired to mark the locations of the potholes, they will be performed off of the utility provider’s marks under the client’s direction. Utility providers typically do not mark out sewer or storm drain lines. Dry holes are considered billable. Locating is a separated line item that will be represented on your estimate.

Client will be provided a detailed potholing report at the conclusion of the investigation.

Quality Level Definitions

Quality Level D is the most basic level of information for utility locations. It comes solely from existing utility records or verbal recollections, both typically unreliable sources. It may provide an overall "feel" for the congestion of utilities, but is often highly limited in terms of comprehensiveness and accuracy. QL-D is useful primarily for project planning and route selection activities.

Quality Level C involves surveying visible utility facilities (e.g., manholes, valve boxes, etc.) and correlating this information with existing utility records (QL-D information). When using this information, it is not unusual to find that many underground utilities have been either omitted or erroneously plotted. Its usefulness, therefore, is primarily on rural projects where utilities are not prevalent, or are not too expensive to repair or relocate.

Quality Level B involves the application of appropriate surface geophysical methods to determine the existence and horizontal position of virtually all utilities within the project limits. It addresses problems caused by inaccurate utility records, abandoned or unrecorded facilities, and lost references. Decisions regarding location of storm drainage systems, footers, foundations and other design features can be made to successfully avoid conflicts with existing utilities. Slight adjustments in design can produce substantial cost savings by eliminating utility relocations.

Quality Level A is the highest level of accuracy and involves the full use of the subsurface utility investigation method. It provides information for the precise plan and profile mapping of underground utilities through the nondestructive exposure of underground utilities, and also provides the type, size, condition, material and other characteristics of underground features.



Service Exceptions and Limitation

Locating Exceptions Our services do not include the location of irrigation lines and associated control valves. We are able to locate sewer and storm drain lines if access is made available. We do not locate abandoned/extra conduits containing no interior cable and we do not locate fiber optic lines or lines without a metallic shield or lacking a tracer wire. C Below has the ability to locate nonmetallic lines but it is outside our normal scope of services. Should the need arise to locate these types of lines, please contact us for an additional quote.

GPR ExceptionsThere needs to be at least 8 inches clearance around the perimeter of the scanning area to accommodate the GPR antenna; especially at structure intersections. Scanning surfaces need to be relatively flat with no water present. GPR can penetrate 12 inches of concrete or masonry, but accuracy decreases with increased steel congestion. Indications show up on the radar screen as hyperbolas. The center of the hyperbola is the center of the indication. GPR data, under most circumstances, does not allow for the interpretation of an indications size, only the center location of the indication and embedment depth. Indications such as reinforcing steel or conduit spaced closer than 2 inches on center may show up as one indication.

Mapping ExceptionsPlease be sure to provide any project documents prior to dispatch. A workable CAD file is required if mapping is to be performed. JPG, TIFF, PDF files are not preferred and may affect the quality of the final product. If no CAD file can be provided, additional costs may apply. A complete and editable background must be provided by the client to ensure the quality of the final product.

Potholing ExceptionsFor billing purposes, C Below defines a standard pothole with the dimensions of 1’ X 1’ X 5’ deep. Deviations from this standard definition require rate increases for additional time and materials to facilitate the client requests. Because potholing rates and other associated costs are based on the assumption of 8 hour work days, additional fees may apply if work is limited to less than 8 hours per day. These fees may include, but are not limited to: additional traffic control, travel time, and disposal fees. Standard pothole pricing includes holes at locations with a soil surface or an asphalt surface up to 6-inches thick. Additional fees will apply if the asphalt surface is over 6” thick or the proposed hole location has a concrete surface. If during the potholing operation the soil is found to have large aggregate or other debris over 3-inches in diameter, ground water, roots or hazardous materials, additional fees will apply. For further clarification please speak to your C Below representative. Optional Services include: hot patching per City requirements, slurry backfill, standard or engineered traffic control plans, trenching or excavation beyond standard pothole dimensions.

CCTV ExceptionsAll lines designated by the client for need of inspection must have clear unobstructed access points. Information gathered during the inspection must be agreed upon prior to dispatch. For added scope of water jetting additional fees apply.

Traffic ControlStandard Traffic Control includes one lane closure with minimal signage not spanning an intersection. Extensive Traffic Control includes multiple lane closures, arrow boards, multiple signage requirements, spanning of intersections, flaggers, and other non-standard setups.

UTILITY LOCATINGUtility locating is an imperative first step prior to geotechnical excavation during pre-construction. Damaged lines are not only expensive to repair but can be extremely dangerous. Starting your project with the knowledge of the types and locations of underground utilities on the job site is an important and cost-effective way to ensure a safe and successful project.

C Below has the ability to locate horizontal and vertical locations for all underground utilities including:water, gas, power, waste, communications and cable/TV.

Our technicians will mark all indications directly on the surface of all surveyed areas using the American Public Works Association (APWA) Uniform Color Code. All utility locating marks are made in accordance with the Common Ground Alliance (CGA) Best Practices.

Once lines have been found, there are several options a technician can use for marking the utility locations. Spray paint is the most common but flags or whiskers are also utilized in areas that have heavy traffic, or where sprinklers may cause the paint to become unreadable prior to excavation. Computer-aided design or CAD drawings of our findings can also be provided upon request.

Our utility locating services shall include only those materials commonly used for locating and marking indications. Clear access to scanning areas need to be provided by the client. Should the area to be scanned not be accessible from the ground, the client will provide the means (man lift, scaffold, etc.) for our technician to properly perform their work.

For utility locating we locate all underground utilities using a standard electromagnetic utility locator. With this method, we are able to find: main water supply lines and associated branch lines made of metal (conductive) or water lines installed with a “tracer wire”, all sewer and waste lines by electromagnetic location, power lines, telecommunication lines, gas lines with tracer wires.

EXCEPTIONSOur services do not include the location of irrigation lines and associated control valves. We are able to locate sewer lines if access is made available. We do not locate abandoned/extra conduits containing no interior cable and we do not locate fiber optic lines or lines without a metallic shield or lacking a tracer wire. C Below has the ability to locate nonmetallic lines but it is outside our normal scope of services. Should the need arise to find these types of lines, please contact us for an additional quote.

GROUND PENETRATING RADAR (GPR)C Below uses GPR for locating reinforcing steel, prestressing strand, conduit and other indications in concrete and masonry structures. We use this method because it is one of the safest, fastest and most accurate methods currently available. With the ability to penetrate up to 18 inches of concrete, our technicians can map all indications directly on the scanning surface prior to coring, cutting or drilling. The survey results can also be saved and printed in 3-Dimensional detail providing a subsurface map for our client.

With such a large penetration range, GPR can be used with access to only one side of the scanning area with no need to place film on the opposite surface (as is needed with other methods). Our technicians determine the thickness of concrete and masonry structures to determine the spacing and depth of indications. In certain cases, the size of the indication can be estimated.

As these indications are found, they are displayed to the technician in real-time. They are displayed on the GPR monitor when changes in the conductivity of the scanned area represent locations of rebar, conduit, pipe, voids, and other objects located beneath the surface. Once located, the indication is marked in accordance with the APWA Uniform Color Code.

GPR is incredibly versatile and offers ease of use on job sites. It emits about 1% the power of a cell phone signal to perform its functions. Other methods require a safety perimeter around work areas. We prefer to use GPR because we are able to work in occupied sites and buildings where temporary evacuation is not an option. The equipment is very portable and can be moved to location quickly, making scanning of multiple areas a fast, efficient and manageable process. The practicality of this service supersedes traditional methods of utility locating, but it can also be used in conjunction with them.

With the ability to locate nonmetallic utilities up to 12 feet deep, you can be sure most lines will be identified.

EXCEPTIONSThere needs to be at least 8 inches clearance around the perimeter of the scanning area to accommodate the GPR antenna; especially at structure intersections. Scanning surfaces need to be relatively flat with no water present. GPR can penetrate 16 inches of concrete or masonry, but accuracy decreases with increased steel congestion. Size of indications are hard to determine as GPR readings are presented in a fashion that communicates location rather than the indication’s expanse.

UNDERGROUND MAPPING

C Below will provide our client with electronic and/or printed documenta-tion of our utility investigation when mapping is added to our locating scope of work. Utility locations will be plotted in a client provided site drawing with clear, easy to read detail. Each utility is labeled and color coded in accordance with the indications marked in the field. We prepare CAD drawings to ensure the industry’s most accurate drawings. The details of these drawings are based upon client specifications. Some of these options include depth, pipe diameter and materials, connection points, and all unknown utilities.

In addition to 36” x 24” prints, our drawings can also be saved in PDF format for simple distribution and viewing. Our detailed drawings can be used to provide designers and contractors with an overview of what to expect when performing site work. All mapping is done under the supervision of a licensed civil engineer.

EXCEPTIONS

Please be sure to provide any project documents prior to dispatch. A workable CAD file is required if mapping is to be performed. JPG, TIFF, PDF files are not preferred and may affect the quality of the final product. If no CAD file can be provided, additional costs may apply. A complete and editable background must be provided by the client to ensure the quality of the final product.

POTHOLINGPotholing is also known as vacuum excavation and is used for the purpose of identifying the axis of an underground utility. When the utility is revealed, the type of material and utility size are documented. The data collected during these excavations are beneficial in all phases of construction. Based upon the soils conditions or scope, C Below will choose to use air or water to create the pothole. Potholes made to expose facilities encased in concrete, will stop at the encasement. The top of the encasement will then be recorded as the top of the facility.

After documenting our findings, each pothole will be backfilled, compacted, and a perm-a-patch or hot patch will be provided depending upon client specifications.

A potholing report complete with photographs are provided at the conclusion of the job documenting the location, utility found, depth to top of pipe, utility size, material and the soil conditions. If no utility is found within the predetermined depth of the pothole, it will be considered a dry hole. Additional holes may be necessary to provide a positive location of the utility.

PRICING & EXCEPTIONSFor billing purposes, C Below defines a standard pothole with the dimensions of 1’ X 1’ X 5’ deep. Deviations from this standard definition require rate increases for additional time and materials to facilitate the client requests. Because potholing rates and other associated costs are based on the assumption of 8 hour work days, additional fees may apply if work is limited to less than 8 hours per day. These fees may include, but are not limited to: additional traffic control, travel time, and disposal fees. Standard pothole pricing includes holes at locations with a soil surface or an asphalt surface up to 6-inches thick. Additional fees will apply if the asphalt surface is over 6” thick or the proposed hole location has a concrete surface. If during the potholing operation the soil is found to have large aggregate or other debris over 3-inches in diameter, ground water, roots or hazardous materials, additional fees will apply. For further clarification please see rate sheet for ‘Out of Scope Hole’ and the table below. Optional Services include: hotpatching per City requirements, stamped traffic control plans by an engineer, routine traffic control plans.

CCTV PIPE INSPECTION AND CRAWLER CAMC Below provides video pipe inspection that will give vital information to help properly maintain utility and pipe facilities. We perform this service on sanitary sewer and storm drain lines specifically identified by the client or client’s representative. CCTV pipe inspection includes trained personnel and the use of a push camera and/or crawler camera depending on the size of the line.

During this inspection, videos are recorded in full color MP4 files that can be viewed easily on all computers. Captions can be added to the video to help identify the technician findings. Our push cameras can video lines as small as 3” in diameter while our crawler cameras can do pipes upwards of 72”. The video technology offers high quality assessment of all piping, including joints. We offer quick results with the ability to transfer video feed via USB and Bluetooth technology.

Standard details recorded during the inspection include: obstructions or blockages, root intrusion, structural damage, pipe offsets and flow conditions. Problem areas found will be identified on the surface for easy identification.

In the event that any blockage is found, we are able to provide water jetting to clear the obstructions. Sanitary Sewer and Storm Drain lines may contain debris and blockages that limit the ability to perform CCTV Pipe Inspection. C Below can arrange for an outside contractor to jet all lines prior to CCTV pipe inspection to ensure the full length of the pipe can be filmed.

EXCEPTIONSAll lines designated by the client for need of inspection must have clear unobstructed access points. Information gathered during the inspection must be agreed upon prior to dispatch. For added scope of water jetting additional fees apply.

Subject: EMWD Perris North Area Noise Study

Attention: Steve Ellis, Senior Project Manager

From: Jason Peetz, Behrens and Associates Environmental Noise Control

Mr. Ellis,

Our task and cost proposal to perform a noise study for the Eastern Municipal Water

District Perris North Groundwater project as follows:

1) Perform an ambient sound level survey at 5 locations (Well Site 204, 66, 65 area) to determine

existing noise levels within the Eastern Municipal Water District Area. A total of 5 noise

measurements of 24-hour duration will document existing sound levels within the area. Type 1

sound level meters will be deployed and programmed to continuously measure and record sound

levels until retrieval the following day.

2) Perform a noise impact model for proposed operational equipment at Well Site 204, 66, 65 and

associated equipment. Using file data or calculations, each noise model will calculate the noise

impact of the proposed equipment at each site taking into account the effects of the site’s

topography, groundcover and existing structures at the site and adjacent surroundings. The noise

impact modeling will be completed using SoundPLAN software, which utilizes the ISO 9613-2

calculation standard. Predicted noise levels will be assessed against the city of San Jacinto noise

standards.

3) If required, noise mitigation recommendations will be provided for each modeling scenario to meet

the noise limits. The noise mitigation recommendations will be included in the noise modeling to

estimate the expected performance. The results of the modeling and final noise mitigation plan will

be outlined in a report.

SCOPE OF SERVICES

EMWD - Final Design Morena Valley and South Area Facilities 3 Extraction Wells

2 Treatment Facilities Various 8-inch, 12-inch, 18-inch Pipelines

Task 3.4 From RFP – Corrosivity Assessment and PDR

1. Review existing site plans, drawings, prep for field.

2. Conduct field resistivity testing at the project site and along pipeline alignments. The

resistivity test data are typically taken at 1,000 foot intervals. Enough test sites will be

selected to determine the general corrosion resistivity of the Project alignment.

3. Coordinate with the project geotechnical subconsultant to obtain and review boring

logs and soil chemical analysis data from soil samples taken along the Project alignment (soil samples obtained and tested by the geotechnical subconsultant). Soil chemical analysis (at minimum) should include pH, sulfate concentration, chloride concentration, and soil box resistivity in the as-received and saturated conditions.

4. Conduct a review for the potential of stray current interference. It is understood that

the Project pipeline may cross several other buried metallic utilities that may be

cathodically protected. Where needed, RFYeager Engineering will contact the other

pipeline Owners to determine where their cathodic protection systems are located and

at what levels their cathodic protection systems are adjusted to. This will help to

determine the potential for stray current on the new EMWD pipelines and will assist in

determining the type of stray current mitigation should they be required.

5. Conduct a cost analysis to determine the capital and O&M costs for an impressed

current cathodic protection system versus a galvanic anode cathodic protection

system. The cost analysis will include all costs associated with installations, materials,

labor, and required electrical service.

6. Provide a Corrosivity Assessment Report to include all test data, observations,

conclusions, and recommendations for corrosion control, materials of construction,

coating options, and stray current mitigation (if necessary). Recommendations for

corrosion control will be based upon sound corrosion engineering practices, District

and AWWA Standards, and the available corrosion control methods and coating

options.

7. Review/implement Client comments and prepare Final Corrosivity Assessment Report.

8. Attend project meetings or Tel Con (1 meeting estimated).

Task 6 From RFP – Cathodic Protection Design

1. Review District Standards for pipeline corrosion control and cathodic protection.

2. Provide corrosion control/cathodic protection design calculations.

3. Provide redline markups to civil plan and profile drawings to include callouts of

corrosion control facilities. These callouts will be added to the civil plan and profile

drawings by Tetra Tech.

4. Provide a 60% cathodic protection/corrosion control design to include detail sheets and

specifications. The detail sheets will be generated using RFYeager Engineering CAD

designers. Tetra Tech will provide RFYeager Engineering with the appropriate title
