REVIEWED BY: Carla Dillon, P.E., Public Works Director
PREPARED BY: Ryan Damon, Associate Engineer
MEETING DATE: July 18, 2023
SUBJECT: Professional Services Agreement with Psomas for the Sanitary Sewer System Master Plan
RECOMMENDATION
Approve a Professional Services Agreement with Psomas for the completion of the Sanitary Sewer System Master Plan in the amount of $125,040 plus a 10% contingency amount of $12,504; appropriate $22,544 from the Sewer Replacement Fund; and authorize the City Manager to execute the agreement.
BACKGROUND
The City of Lomita’s sanitary sewer collection system serves a population of approximately 20,000 residents and consists of roughly 36 miles of gravity sewer lines.
The City’s legal authority to own and operate the sanitary sewer system is derived from its incorporation as a City. The City, on June 30, 1964, granted the County of Los Angeles the consent and jurisdiction to annex portions of the sewer system into the Consolidated Sewer Maintenance District (CSMD). By that action, the City has entrusted the management, operation, and maintenance of its local sanitary sewer system the CSMD.
The City, however, maintains ownership of the sewer system, and is responsible for ensuring that the public sewer infrastructure is correctly designed, adequately sized, and easily maintained. Although the CSMD will repair damaged pipes, it will not upsize or add pipes if land development increases sewer volume, or other modifications become necessary. In addition, the City does not currently collect any fees for sewer improvements. Sewer fees for maintenance are collected by Los Angeles County for the use by CSMD, but the city collects no fees for improvements.
In the City’s history, a sewer master plan has not been completed. With many new developments, including additional housing units planned in the coming years, the City Item No. 7j
CITY OF LOMITA
CITY COUNCIL REPORT
2 recommends the completion of a sewer master plan to ensure sufficient sewer capacity for future needs. The purpose of the Sanitary Sewer System Master Plan is to analyze and assess the City’s existing sewer infrastructure to address capacity deficiencies in the system. Deficiencies will be identified and prioritized in a specific list of projects for a 10- year Capital Improvement Plan (CIP). The study will include recommendations and development and calibration of a sewer hydraulic model that will validate the recommendations made in the Master Plan. This will provide the City a tool for future analysis capacity development, and could provide a baseline of existing conditions to assist in the future development of an appropriate sewer fee structure.
On April 11, 2023, staff issued a Request for Proposal (RFP) to nineteen (19) qualified civil engineering firms specializing in the pipeline rehabilitation design and utility master plans. Two (2) engineering firms responded with proposals. After a review of the engineering team qualifications, experience with similar projects, and recent relevant project experience from the proposing firms, staff conducted an interview with the highest ranked firm to further discuss the project’s scope as well as the firm’s understanding and experience with similar sewer studies.
Psomas received the highest rankings, as they possessed the best overall scope of work and a thorough understanding of the City’s needs for this project as outlined in the RFP.
Psomas is a full-service consulting firm, providing water, sewer, and wastewater engineering services, as well as GIS consulting services. They also have extensive experience with infrastructure projects for public agencies and a deep understanding of the jurisdictional procedures and regulations needed to complete sewer system master plans. Founded in 1946, Psomas has about 740 employees in offices in California, Arizona, Washington, and Utah. They have completed similar sewer studies for numerous agencies, such as the Cities of Yorba Linda, Anaheim, Gonzales, and Los Alamitos. Their staff are well-experienced in sewer studies as well as sewer pipeline and sewer utility design. Based on their proposal and project needs, staff negotiated a final scope and fees with Psomas in the amount of $125,040 for Engineering Services for the project. Staff recommends approval of a 10% contingency, in the amount of $12,504 which will be added to the total budget and included in the agreement.
The design of the project is scheduled to start in August 2023 and is expected to be completed in eight months.
3 FISCAL IMPACT
The design project is planned to be funded as follows in the FY23-24 Budget:

All violations of such laws and regulations shall be grounds for CITY to terminate the Agreement for cause.
13. PREVAILING WAGE.
A. Prevailing Wage. CONTRACTOR is aware of the requirements of California Labor Code Section 1720, et seq., and 1770, et seq., as well as California Code of Regulations, Title 8, Section 16000, et seq., ("Prevailing Wage Laws"), which require the payment of prevailing wage rates and the performance of other requirements on "public works" and "maintenance" projects. If the services are being performed as part of an applicable "public works" or "maintenance" project, as defined by the Prevailing Wage Laws, and if the total compensation is $1,000 or more, CONTRACTOR agrees to fully comply with such Prevailing Wage Laws.
Upon request, CITY shall provide CONTRACTOR with a copy of the prevailing rates of per diem wages in effect at the commencement of this Agreement.
CONTRACTOR shall make copies of the prevailing rates of per diem wages for each craft, classification or type of worker needed to execute the services available
to interested parties upon request and shall post copies at the CONTRACTOR’S principal place of business and at the project site. It is the intent of the parties to effectuate the requirements of sections 1771, 1774, 1775, 1776, 1777.5, 1813, and 1815 of the Labor Code within this Agreement, and CONTRACTOR shall therefore comply with such Labor Code sections to the fullest extent required by law.
CONTRACTOR shall defend, indemnify and hold the CITY, its officials, officers, employees, agents, and volunteers free and harmless from any claim or liability arising out of any failure or alleged failure to comply with the Prevailing Wage Laws.
B. Registration/DIR Compliance. If the services are being performed on a public works project of over $25,000 when the project is for construction, alteration, demolition, installation, or repair work, or a public works project of over $15,000 when the project is for maintenance work, in addition to the foregoing, then pursuant to Labor Code sections 1725.5 and 1771.1, CONTRACTOR and all subcontractors must be registered with the Department of Industrial Relations (“DIR”). CONTRACTOR shall maintain registration for the duration of the project and require the same of any subcontractors. This project may also be subject to compliance monitoring and enforcement by the DIR. It shall be CONTRACTOR’S sole responsibility to comply with all applicable registration and labor compliance requirements, including the submission of payroll records directly to the DIR. Any stop orders issued by the DIR against CONTRACTOR or any subcontractors that affect CONTRACTOR’S performance of services, including any delay, shall be CONTRACTOR’S sole responsibility. Any delay arising out of or resulting from such stop orders shall be considered CONTRACTOR caused delay and shall not be compensable by CITY.
CONTRACTOR shall defend, indemnify and hold CITY, its officials, officers, employees and agents free and harmless from any claim or liability arising out of stop orders issued by the DIR against CONTRACTOR or any subcontractor.
C. Labor Certification. By its signature hereunder, CONTRACTOR certifies that it is aware of the provisions of Section 3700 of the California Labor Code which require every employer to be insured against liability for Worker's Compensation or to undertake self-insurance in accordance with the provisions of that Code and agrees to comply with such provisions before commencing the performance of the Services.
D. Employment of Apprentices. CONTRACTOR and all subcontractors shall comply with the requirements of Labor Code sections 1777.5 and 1777.6 in the employment of apprentices.

E. CONTRACTOR or subcontractors may not perform work on a public works project with a subcontractor who is ineligible to perform work on a public project pursuant to Labor Code section 1777.1 or 1777.7. Any contract on a public works project entered into between the CONTRACTOR and a debarred subcontractor is void as a matter of law. A debarred subcontractor may not receive any public money for performing work as a subcontractor on a public works contract. Any public money
that is paid or may have been paid to a debarred subcontractor by CONTRACTOR on the project shall be returned to CITY. The CONTRACTOR shall be responsible for the payment of wages to workers of a debarred subcontractor who has been allowed to work on the Project.
F. CONTRACTOR agrees to bind every subcontractor to the terms of the Agreement as far as such terms are applicable to subcontractor’s portion of the work.
CONTRACTOR shall be as fully responsible to CITY for the acts and omissions of its subcontractor and of persons either directly or indirectly employed by its subcontractor, as CONTRACTOR is for acts and omissions of persons directly employed by CONTRACTOR. Nothing contained in these Agreement shall create any contractual relationship between any subcontractor and CITY.
14. TERMINATION.
A. Except as otherwise provided, CITY may terminate this Agreement at any time with or without cause. Notice of termination shall be in writing.
B. CONTRACTOR may terminate this Agreement. Notice will be in writing at least 30 days before the effective termination date.
C. In the event of such termination, CONTRACTOR shall cease services as of the date of termination, all finished or unfinished documents, data, drawings, maps, and other materials prepared by CONTRACTOR shall, at CITY’s option, become CITY’s property, and CONTRACTOR will receive just and equitable compensation for any work satisfactorily completed up to the effective date of notice of termination.
D. Should the Agreement be terminated pursuant to this Section, CITY may procure on its own terms services similar to those terminated.
15. INDEMNIFICATION.
A. CONTRACTOR shall indemnify, defend with counsel approved by CITY, and hold harmless CITY, its officers, officials, employees and volunteers from and against all liability, loss, damage, expense, cost (including without limitation reasonable attorneys fees, expert fees and all other costs and fees of litigation) of every nature arising out of or in connection with CONTRACTOR's performance of work hereunder or its failure to comply with any of its obligations contained in this AGREEMENT, regardless of CITY’S passive negligence, but excepting such loss or damage which is caused by the sole active negligence or willful misconduct of CITY. Should CITY in its sole discretion find CONTRACTOR’S legal counsel unacceptable, then CONTRACTOR shall reimburse CITY its costs of defense, including without limitation reasonable attorneys fees, expert fees and all other costs and fees of litigation.
CONTRACTOR shall promptly pay any final judgment rendered against CITY (and its officers, officials, employees and volunteers) covered by this indemnity obligation. It is expressly understood and agreed that the foregoing provisions are intended to be as broad and inclusive as is permitted by the law of the State
of California and will survive termination of this Agreement.
B. The requirements as to the types and limits of insurance coverage to be maintained by CONTRACTOR as required by Section 19, and any approval of said insurance by CITY, are not intended to and will not in any manner limit or qualify the liabilities and obligations otherwise assumed by CONTRACTOR pursuant to this Agreement, including, without limitation, to the provisions concerning indemnification.
16. ASSIGNABILITY. This Agreement is for CONTRACTOR’s professional services.
CONTRACTOR’s attempts to assign the benefits or burdens of this Agreement without CITY’s written approval are prohibited and will be null and void.
17. INDEPENDENT CONTRACTOR. CITY and CONTRACTOR agree that THE CONTRACTOR will act as an independent contractor and will have control of all work and the manner in which it is performed. THE CONTRACTOR will be free to contract for similar service to be performed for other employees while under contract with CITY. CONTRACTOR is not an agent or employee of CITY and is not entitled to participate in any pension plan, insurance, bonus or similar benefits CITY provides for its employees. Any provision in this Agreement that may appear to give CITY the right to direct CONTRACTOR as to the details of doing the work or to exercise a measure of control over the work means that CONTRACTOR will follow the direction of the CITY as to end results of the work only.
18. AUDIT OF RECORDS.
A. THE CONTRACTOR agrees that CITY, or designee, has the right to review, obtain, and copy all records pertaining to the performance of this Agreement.
CONTRACTOR agrees to provide CITY, or designee, with any relevant information requested and will permit CITY, or designee, access to its premises, upon reasonable notice, during normal business hours for the purpose of interviewing employees and inspecting and copying such books, records, accounts, and other material that may be relevant to a matter under investigation for the purpose of determining compliance with this Agreement.
CONTRACTOR further agrees to maintain such records for a period of three (3) years following final payment under this Agreement.
B. CONTRACTOR will keep all books, records, accounts and documents pertaining to this Agreement separate from other activities unrelated to this Agreement.
19. CORRECTIVE MEASURES. CONTRACTOR will promptly implement any corrective measures required by CITY regarding the requirements and obligations of this Agreement. CONTRACTOR will be given a reasonable amount of time as determined by CITY to implement said corrective measures. Failure of CONTRACTOR to implement required corrective measures shall result in immediate termination of this Agreement.
20. INSURANCE REQUIREMENTS.
A. CONTRACTOR, at CONTRACTOR’s own cost and expense, shall procure and maintain, for the duration of the contract, the following insurance policies:
1. Workers Compensation Insurance as required by law. CONTRACTOR shall require all subcontractors similarly to provide such compensation insurance for their respective employees. Any notice of cancellation or non-renewal of all Workers’ Compensation policies must be received by CITY at least thirty (30) days prior to such change. The insurer shall agree to waive all rights of subrogation against CITY, its officers, agents, employees, and volunteers for losses arising from work performed by CONTRACTOR for CITY.
2. General Liability Coverage. CONTRACTOR shall maintain commercial general liability insurance in an amount of not less than one million dollars ($1,000,000) per occurrence for bodily injury, personal injury, and property damage. If a commercial general liability insurance form or other form with a general aggregate limit is used, either the general aggregate limit shall apply separately to the work to be performed under this Agreement or the general aggregate limit shall be at least twice the required occurrence limit.
3. Automobile Liability Coverage. CONTRACTOR shall maintain automobile liability insurance covering bodily injury and property damage for all activities of CONTRACTOR arising out of or in connection with the work to be performed under this Agreement, including coverage for owned, hired, and non-owned vehicles, in an amount of not less than one million dollars ($1,000,000) combined single limit for each occurrence.
4. Professional Liability Coverage. CONTRACTOR shall maintain professional errors and omissions liability insurance for protection against claims alleging negligent acts, errors, or omissions which may arise from CONTRACTOR’S operations under this Agreement, whether such operations be by CONTRACTOR or by its employees, subcontractors, or subcontractors. The amount of this insurance shall not be less than one million dollars ($1,000,000) on a claims-made annual aggregate basis, or a combined single-limit-per-occurrence basis. When coverage is provided on a “claims made basis,” CONTRACTOR will continue to renew the insurance for a period of three (3) years after this Agreement expires or is terminated.
Such insurance will have the same coverage and limits as the policy that was in effect during the term of this Agreement, and will cover CONTRACTOR for all claims made by CITY arising out of any errors or omissions of CONTRACTOR, or its officers, employees or agents during the time this Agreement was in effect.
B. Endorsements. Each general liability, automobile liability and professional liability insurance policy shall be issued by a financially responsible insurance company or companies admitted and authorized to do business in the State of
California, or which is approved in writing by CITY, and shall be endorsed as follows. CONTRACTOR also agrees to require all contractors, and subcontractors to do likewise.
1. “The CITY, its elected or appointed officers, officials, employees, agents, and volunteers are to be covered as additional insureds with respect to liability arising out of work performed by or on behalf of the CONTRACTOR, including materials, parts, or equipment furnished in connection with such work or operations.”
2. This policy shall be considered primary insurance as respects CITY, its elected or appointed officers, officials, employees, agents, and volunteers.
Any insurance maintained by CITY, including any self-insured retention CITY may have, shall be considered excess insurance only and shall not contribute with this policy.
3. This insurance shall act for each insured and additional insured as though a separate policy had been written for each, except with respect to the limits of liability of the insuring company.
4. The insurer waives all rights of subrogation against CITY, its elected or appointed officers, officials, employees, or agents.
5. Any failure to comply with reporting provisions of the policies shall not affect coverage provided to CITY, its elected or appointed officers, officials, employees, agents, or volunteers.
6. The insurance provided by this policy shall not be suspended, voided, canceled, or reduced in coverage or in limits except after thirty (30) days’ written notice has been received by CITY.
C. CONTRACTOR agrees to provide immediate notice to CITY of any claim or loss against Contractor arising out of the work performed under this agreement.
CITY assumes no obligation or liability by such notice, but has the right (but not the duty) to monitor the handling of any such claim or claims if they are likely to involve CITY.
D. Any deductibles or self-insured retentions must be declared to and approved by CITY. At CITY’s option, CONTRACTOR shall demonstrate financial capability for payment of such deductibles or self-insured retentions.
E. CONTRACTOR shall provide certificates of insurance with original endorsements to CITY as evidence of the insurance coverage required herein.
Certificates of such insurance shall be filed with CITY on or before commencement of performance of this Agreement. Current certification of insurance shall be kept on file with CITY at all times during the term of this Agreement.
F. Failure on the part of CONTRACTOR to procure or maintain the required insurance shall constitute a material breach of contract under which CITY may terminate this Agreement pursuant to Section 13 above.
G. The commercial general and automobile liability policies required by this Agreement shall allow CITY, as additional insured, to satisfy the self-insured retention (“SIR”) and/or deductible of the policy in lieu of the CONTRACTOR (as the named insured) should CONTRACTOR fail to pay the SIR or deductible requirements. The amount of the SIR or deductible shall be subject to the approval of the City Attorney and the Finance Director. CONTRACTOR understands and agrees that satisfaction of this requirement is an express condition precedent to the effectiveness of this Agreement. Failure by CONTRACTOR as primary insured to pay its SIR or deductible constitutes a material breach of this Agreement. Should CITY pay the SIR or deductible on CONTRACTOR’S behalf upon CONTRACTOR’S failure or refusal to do so to secure defense and indemnification as an additional insured under the policy, CITY may include such amounts as damages in any action against Contractor for breach of this Agreement in addition to any other damages incurred by CITY due to the breach.
21. USE OF OTHER CONTRACTORS. THE CONTRACTOR must obtain CITY’s prior written approval to use any Contractors while performing any portion of this Agreement. Such approval must include approval of the proposed Contractor and the terms of compensation.
22. FINAL PAYMENT ACCEPTANCE CONSTITUTES RELEASE. The acceptance by the CONTRACTOR of the final payment made under this Agreement shall operate as and be a release of CITY from all claims and liabilities for compensation to the CONTRACTOR for anything done, furnished or relating to the CONTRACTOR’S work or services. Acceptance of payment shall be any negotiation of CITY’S check or the failure to make a written extra compensation claim within ten (10) calendar days of the receipt of that check. However, approval or payment by CITY shall not constitute, nor be deemed, a release of the responsibility and liability of CONTRACTOR, its employees, sub-Contractors and agents for the accuracy and competency of the information provided and/or work performed; nor shall such approval or payment be deemed to be an assumption of such responsibility or liability by CITY for any defect or error in the work prepared by CONTRACTOR, its employees, sub-Contractors and agents.
23. CORRECTIONS. In addition to the above indemnification obligations, the CONTRACTOR shall correct, at its expense, all errors in the work which may be disclosed during the CITY’S review of CONTRACTOR’S report or plans. Should the CONTRACTOR fail to make such correction in a reasonably timely manner, such correction shall be made by CITY, and the cost thereof shall be charged to CONTRACTOR. In addition to all other available remedies, CITY may deduct the cost of such correction from any retention amount held by CITY or may withhold payment otherwise owed CONTRACTOR under this Agreement up to the amount of the cost of correction.
24. NON-APPROPRIATION OF FUNDS. Payments to be made to CONTRACTOR by CITY for services preformed within the current fiscal year are within the current fiscal budget and within an available, unexhausted fund. In the event that CITY does not appropriate sufficient funds for payment of CONTRACTOR’S services beyond the current fiscal year, the Agreement shall cover payment for CONTRACTOR’S only to the conclusion of the last fiscal year in which CITY appropriates sufficient funds and shall automatically terminate at the conclusion of such fiscal year.

GENERAL INFORMATION
A. INTRODUCTION / BACKGROUND
The City of Lomita is requesting proposals from qualified and experienced Civil Engineering firms to provide Engineering Services to conduct and prepare the City’s Sanitary Sewer System Master Plan. Included in the scope of work for the project, the selected Consultant shall recommend, produce and calibrate a Sewer System Hydraulic Model for the City’s sewer infrastructure.
The City of Lomita is an urban, densely populated 1.97 square miles (total area is 1,261 acres), located at the base of the Palos Verdes Peninsula in the Los Angeles Basin, Los Angeles County, 26 miles south of downtown Los Angeles and bounded by the City of Torrance on the north and west, the Harbor Region of Los Angeles to east, and the City of Rolling Hills Estates on the southwest; and the City of Rancho Palos Verdes and unincorporated Los Angeles County area to the southeast. The City is almost completely developed with mostly residential neighborhoods and commercial units.
The City’s sanitary sewer collection systems serves a population of approximately 20,000 residents and consists of roughly 36 miles of gravity sewer lines. The City’s legal authority to own and operate the sanitary sewer system is derived from its incorporation as a City. The City, on June 30, 1964, granted the County of Los Angeles the consent and jurisdiction to annex portions of the sewer system into the Consolidated Sewer Maintenance District (CSMD). By that action, the City has entrusted the management, operation, and maintenance of its local sanitary sewer system the CSMD. The City, however, maintains ownership of the sewer system, and is responsible for ensuring that the public sewer infrastructure is correctly designed, adequately sized, and easily maintained.
B. PROJECT DESCRIPTION
The purpose of the Sanitary Sewer System Master Plan is to analyze and assess the City’s existing sewer infrastructure to address capacity deficiencies in the system. Deficiencies will be identified and prioritized in a specific list of projects, a 10-year Capital Improvement Plan (CIP) that will look to replace, rehabilitate, and maintain the sewer facilities and infrastructure. The selected Consultant will also be responsible for the recommendation, development and calibration of a sewer hydraulic model that will validate the recommendations made in the Master Plan and used by the City for future analysis.

Arbor Street and Locust Avenue Sewer Improvement (2019 to 2022) Psomas conducted a sewer study of approximately 15,000 LF of sewer mains in Los Angeles County, including problematic portions of the system such as a sewer siphon under a major storm channel, a crossing under the UPRR railroad, and sewers running through a mobile home park. Using LBWD’s GIS and flow monitoring data, Psomas developed a hydraulic model to identify capacity deficiencies and proposed five (5) potential system improvement alternatives to address them. The study also included sewer maintenance hole surveys, utility research, and collaboration with LBWD staff to suggest a sixth alternative, resulting in a final preliminary design report with recommendations for capital improvements. 6 CITY OF LOMITA | Sanitary Sewer System Master Plan 5

2010 and 2022 Wastewater Master Plan
Yorba Linda, CA | Yorba Linda Water District
In 2010 Psomas prepared Yorba Linda Water District’s sewer master plan, teamed with IDModeling. Psomas was also selected to prepare the 2022 Wastewater Master Plan Update. Since 2010, the District almost doubled its sewer service area taking over the eastern portion of the sewer system that was previously under the control of the City of Yorba Linda.
This 2022 Wastewater Master Plan not only updated the western portion of the District’s collection system but also developed a completely new hydraulic model of the eastern portion, including a tributary area of approximately 3,400 acres. The 2022 Master Plan involved updating the existing InfoSewer model in the western area to include new capital improvements and new developments; updating the District’s GIS in the western area to be consistent with the updated model; constructing a new InfoSewer model in the eastern area from the District’s GIS; and conducting extensive sewer flow monitoring to check and readjust calibration of the model in the western area and to calibrate the new model in the eastern area.
Build-out land use projections and sewer flow loading for build-out conditions were generated. Then, existing and build-out scenarios were modeled to develop a capital improvement program. Finally, a complete sewer master plan document was prepared for review and approval by the District. The entire study area in this District-wide hydraulic model comprises 9,000 acres.

South Central Anaheim Sewer Study
Anaheim, CA | City of Anaheim
Psomas was retained by the Public Works Department to conduct a sewer study within an approximately 1,800-acre area tributary to two major trunk sewer systems within an area of Anaheim serving the Anaheim Resort, Disneyland, the Platinum Triangle, and portions of the Downtown area. These areas are tributary to the Katella Avenue and Ball Road trunk sewer systems and, based on modeling previously conducted by Psomas in the Central Area Sanitary Sewer Master Plan, will have capacity constraints in build-out scenarios.
Psomas collaborated with City staff to develop various potential alternative improvement projects primarily centered around diversions of flow to other tributary systems with excess capacity to free up capacity in the constrained pipeline reaches. The alternatives were then analyzed for feasibility based on elevation, slope, and scenario modeling using the City’s InfoSewer hydraulic model developed by Psomas.
Planning level construction costs were developed for each alternative. Alternatives with slopes that were too flat, that did not provide adequate capacity improvement, and/or were too expensive for the capacity provided were eliminated.
The more feasible alternatives were then evaluated
in more detail to a concept design level through
utility research to determine if fatal flaws existed,
such as a conflict with a major storm drain facility
or Metropolitan Water District transmission line
that could prohibit construction. The remaining
alternatives were then ranked and recommended
capital improvements were developed that will
maximize the available capacity in the City sewer
collection system and enable the City to provide
adequate sewer service to continue planned growth
within the study area.

On-Call Design Services for CIP Sewer Improvements
Hermosa Beach, CA | City of Hermosa Beach
Psomas was contracted by the City of Hermosa Beach to complete a sewer rehabilitation project under an on-call contract. Following the completion of the project, the City of Hermosa Beach again contracted Psomas to prepare plans and specifications for additional sewer lining and replacement in six areas, which were derived from the 2017 Sewer Master Plan (SMP).
To evaluate the existing conditions of the selected sewer segments, NASSCO-certified engineers from Psomas analyzed CCTV reports and videos and categorized each segment into five different categories, namely remove and replace, point repair, line pipe, deposit/root removal, or no repair. This allowed the team to determine which segments required rehabilitation and what type of repair was necessary.
Despite the City’s sewer system reaching the end of its design life, the engineers found that most of the pipes were in good condition overall and not structurally compromised. This discovery allowed for a reduction in the amount of remove and replace from 10,900 LF to 4,500 LF and an increase in the amount of lining from 1,700 LF to 7,900 LF. This resulted in significant construction cost savings, which allowed for additional segments to be added to the original scoped segments within the engineering design contract.
In addition to evaluating the sewer segments, Psomas also performed a field evaluation of 116 sewer manholes within the project area to determine if the SMP recommendations for improvement were confirmed or required supplemental modifications. The final design plans included 4,500 LF of remove and replace segments, 100 LF of point repairs at 12 locations, 8,000 LF of lining, 20 LF of deposit and root removal, and 57 rehabilitated manholes.
At the City’s request to align with the annual budget, the project was divided into two separate construction document packages. Psomas will also provide construction support services including attending construction meetings, reviewing shop drawings, and addressing contractor requests for information (RFI). By delivering high-quality engineering design, consulting, and construction management services, Psomas has helped the City of Hermosa Beach to improve its sewer system and reduce the potential for future structural damage.

General and Special Engineering Services
Rossmoor and Los Alamitos, CA | Rossmoor/Los Alamitos Area Sewer District Psomas has served as District Engineer for the Rossmoor/Los Alamitos Area Sewer District (RLAASD) since January 2014. The RLAASD owns and maintains approximately 341,800 feet of VCP sewer ranging in size from 8 to 18 inches in diameter in the City of Los Alamitos, the unincorporated Rossmoor area of Orange County, and portions of the City of Seal Beach. District Engineer, Maira Salcedo, is responsible for overseeing all engineering-related matters, including but not limited to review and approval of developer’s plans, maintenance of the District’s GIS sewer system files, coordination of annual CCTV coverage with the District’s sewer cleaning and maintenance operator, and attendance at District Board of Director meetings on an as-needed basis.
Psomas is also responsible for reviewing approximately 20,000 to 40,000 LF of sewer system CCTV inspections annually and making appropriate recommendations. Between 2014 and 2022, Psomas reviewed approximately 199,720 LF of sewer pipe (60% of the sewer system). Based on the CCTV review by Psomas’ NASSCO PACP/MACP certified engineers, appropriate recommendations for repairs were assessed.
The repairs were executed through the design, bid phase, and construction services of the 2015 Sewer Repair Project and the 2018 Sewer Repair Project in various locations within the District. The 2021 Sewer Repair Project is currently in the process of being designed. Rehabilitation methods include CIPP Lining, UV-cured point repairs, removal, and replacement, and point repairs. Using a combination of various rehabilitation methods and mechanical cleaning equipment to mitigate calcium deposits at various locations, Psomas’ design was able to maximize the amount of lineal footage rehabilitated to enhance the pipeline life cycle.
As the District Engineer, Maira is also responsible for the review and inspection of developer-initiated projects to verify the RLAASD’s standards are met. Psomas is responsible for assessing the initial hydraulic analysis (if determined necessary by the District Engineer), plan check and inspection deposits, and tracking the budget status. In the event the initial deposit is expended, Psomas is responsible for assessing the additional fees and coordinating with the developer’s representative receipt of additional

fees. Since 2014, Psomas has plan checked and
inspected approximately 12 developer projects,
ranging from new lateral connections to new sewer
pipes and manholes serving a tract development.
If deemed necessary by the District Engineer,
Psomas staff performed hydraulic studies to assess
the sewer system capacity prior to initiating
the plan check review. Once a project has been
inspected and accepted by the District Engineer,
Psomas staff review the developer-provided record
drawings, assign a record as-built number, file,
cross references the sewer as-builts to reflect the
modifications to the original record drawings, and
update the GIS as necessary.
At the Board of Directors’ direction, Maira
updated the RLAASD’s Standard Drawings
and Specifications and provided two separate
documents. The first document was written
to apply to projects being designed, bid, and
constructed by private entities/residents and
serving private entities/residents, referred to as
a “Developer Project.” The second document was
written to apply to projects being designed, bid, and
constructed by the RLAASD or its representative(s),
referred to as a “District Project.”
In a review of the RLAASD’s annual maintenance
schedule, infrastructure age vs. design life, and
the District Board of Directors’ goal to extend the
life of the existing sewer infrastructure, Psomas
staff issued a Request for Proposals reviewed and
recommended a firm to prepare a Comprehensive
Sewer Service User Fee and Charges Rate Study
for a five-year service period. Psomas staff assisted
with data gathering and coordination with the
RLAASD, Orange County Assessor’s Office, and
Orange County Sanitation District (OCSD). The
ultimately approved approach to assessing charges
to parcels involved the Equivalent Dwelling Unit
(EDU) methodology, where the charge for one
single-family residence (SFR) dwelling unit is
defined as one EDU. Wastewater service charges for
multi-family, multiple unit, commercial and other
customers are charged a percentage or multiple
of the EDU charge based on their proportion of
flow relative to the SFR. As the District Engineer,
Maira spearheaded the preparation and issuance
of the Proposition 218 Notice to all property
owners within the RLAASD. As part of the annual
maintenance of the adopted user fees and charges,
Psomas reviews the Auditor-Controller parcel
listings and prepares the Direct Charges/Special
Assessment Data file, and uploads it to the Orange
County Auditor-Controller direct charges upload
system to be included in the annual Secured
Property Tax Roll per the Orange County AuditorController’s requirements.
During Psomas’ tenure as District Engineer, its
staff prepared a District-wide sewer hydraulic
study, Sewer System Management Plan (SSMP),
and ongoing support on an as-needed basis as
determined by the RLAASD General Manager,

Project Understanding
The City of Lomita (City) is requesting proposals from qualified civil engineering firms to provide engineering services to conduct and prepare the City’s Sanitary Sewer System Master Plan (Master Plan). The project scope includes analyzing and assessing the City’s existing sewer infrastructure to address condition and capacity deficiencies in the system. Psomas will also develop a 10-year Capital Improvement Plan (CIP) that will look to replace, rehabilitate, and maintain the sewer facilities and infrastructure. Additionally, Psomas will be responsible for developing a sewer hydraulic model that will validate the recommendations made in the Master Plan and can be used by the City for future analysis.
The City of Lomita is a densely populated area with a mostly residential neighborhood and commercial units. The City’s legal authority to own and operate the sanitary sewer system is derived from its incorporation as a City.
The City has entrusted the management, operation, and maintenance of its local sanitary sewer system to the Consolidated Sewer Maintenance District (CSMD). However, the City is responsible for confirming that the public sewer infrastructure is correctly designed, adequately sized, and easily maintained.
The goal of the project is to collect and review all significant data to complete the Sanitary Sewer System Master Plan and develop a sewer hydraulic model and a capital improvement program (CIP). Additionally, key system data should be developed for use in the development of Sewer Impact Fees. Site investigations will be conducted, as needed, to confirm information from existing reports and records. The estimated duration to complete the Sanitary Sewer System Master Plan is eight (8) months.
To complete this work effort, Psomas proposes the tasks detailed in the following Scope of Work. Our hands-on project management approach, consistent and proactive communication, and established QA/QC procedures will deliver the project on time and within budget. The tasks presented in the RFP are included in the proposed Scope of Work but are reordered to correlate with the proposed work plan timeline.
Project Tasks
TASK 1
GENERAL ADMINISTRATION, MEETINGS, AND PRESENTATIONS
Psomas will collaborate with City staff each step of the way through regular progress meetings, Technical Memoranda, workshops, and site visits. The City’s input and buy-in on approach, methodology, and conclusions are essential in moving forward through the planning process and developing the tools that will be most useful to the City in addressing deficiencies and proactively maintaining the sewer infrastructure. The Technical Memoranda are meant to document key assumptions and conclusions along the way so that City staff can review and provide input during the course of the master plan preparation, thus avoiding surprises during review of the draft Master Plan report. All Technical Memos and supporting data will be included in the appendices of the report.
Our Project Manager, Mike Swan, will be the point of contact for the work effort and will coordinate all communication with City staff. Ongoing communication with City staff regarding scheduling, data needs, key decisions and assumptions, and review of sections as they are completed will confirm the Master Plan is completed in a timely manner (per agreed upon schedule). Documents and data will be uploaded and shared in a project folder on the Psomas ProjectWeb. This will allow easy access to all project team members and confirm document security.

REVIEW EXISTING DOCUMENTS, DATA,
AND INFORMATION
Psomas will collect and review all pertinent data
obtained from the City, Los Angeles County Public
Works, and the County Consolidated Sewer Maintenance
District (CSMD) to be used in the preparation of the
2023 Sanitary Sewer System Master Plan. Useful
information will include, as available, as-built and
other sewer plans; CCTV and condition reports;
the latest CSMD Sewer System Management Plan
(SSMP); site-specific sewer studies and other planning
documents; sewer infrastructure data; flow metering
records; GIS data; CAD mapping; current operations
and maintenance practices; and information collected
from communication with City and CSMD staff. Psomas
will provide City staff with a Request for Information
in Excel format at project kick-off where key staff and due dates will be assigned. Psomas staff will arrange
and conduct thorough site investigations, as needed, to confirm information from existing records and reports.
Psomas has conducted an initial review of the City’s
sewer infrastructure data and understands the system
layout and sewer basins. This review was based on GIS
data provided by Los Angeles County Public Works that
include pipeline alignment, diameter, and material.
Invert elevation and related pipeline slope data is not included in the GIS. As-built plans were also reviewed
as available through the LA County Public Works Land
Records Information website. Through our initial
research and evaluation, it was determined that plans
are available for the majority of the City’s sewer system.
This review found PDF plans for more than 80 percent
of the City’s sewer pipelines by length available through the County’s online data. A more thorough review,
as part of this project, will likely identify and locate additional plans. Psomas will build on the City’s exiting sewer GIS with data from these as-built plans. Psomas
has provided an optional task, as needed and described
in this Scope of Work, to survey and dip manholes to
address key data exceptions and datum issues.

2 SCOPE OF WORK AND PROJECT APPROACH
Maira recently completed projects for the Rossmoor/
Los Alamitos Area Sewer District (RLAASD), City of
Hermosa Beach, and Irvine Ranch Water District
(IRWD) where they were responsible for review of
CCTV information, assessment of the conditions of
existing sewage infrastructure, recommendations
for the appropriate rehabilitation methods, and
preparation of construction cost estimates for the
recommended rehabilitation. Psomas also went on to
design and provide construction support services for
the recommended improvements.
This proposal includes a CCTV inspection review
for 15 percent of the City’s pipelines (30,000 LF). The inspections will be used to perform a detailed pipeline assessment for the selected sewer pipe segments and
as a sample representation of the overall condition of
the sewer system. Upon review, Psomas will provide
a recommended rehabilitation method along with a
justification/rationale for each sewer segment. As part of the review/recommendation process, Psomas will
take into consideration the sewer segment location and
note potential construction activity and cost impacts
for the City’s consideration. The recommendations
may consist of complete pipeline and manhole
replacement in the same trench; excavation, and
performance of point repairs; lining sewer segments
in between existing manholes; lining sewer sections;
or a combination of methods. Rehabilitation methods
will place priority on trenchless repairs to minimize
excavation and impacts on the community.
Psomas will consider the various trenchless
technologies and make a recommendation as to the
most viable method for the rehabilitation of each
sewer segment. Two potential trenchless methods for
consideration include the following:
f Cured-In-Place Pipe (CIPP): The liner is
constructed of a tubular layer(s) of non-woven
polyester felt with an exterior polyurethane
coating. The liner is positioned in-place and inflated
using air pressure or a water column to cure the
material against the host pipe.
f Ultraviolet Light Cured Fiberglass Cured-InPlace Pipe (UV CIPP): The liner is constructed of polyester reinforced with spiral-wound fiberglass.
The liner is positioned in place and inflated using air pressure. The liner is cured with ultraviolet light.
The Master Plan will include the finalized rehabilitation recommendations, exhibits to provide a general
visual representation of the recommended repairs,
and cost estimates for incorporation into a capital
improvement program. Based on the estimated cost of
the recommended repairs and the percentage of the City
sewers evaluated from CCTV records provided by the City, an estimated annual amount for the City to budget for
sewer repair and rehabilitation will be generated. In the future, as an additional percentage of the City is CCTV’d and evaluated, this budget amount can be adjusted up or down as appropriate.
Evaluate Operation and Maintenance (O&M)
Practices
Psomas will consult with City and CSMD staff regarding
current O&M procedures and coordinate with staff to
identify opportunities and improvements to the current
levels of service to confirm the sanitary sewer collection system is properly maintained and inspected to reduce
and prevent overflows, which impact public health, the
environment, and the beneficial uses of Waters of the State.

flow monitoring to assess the remaining capacity of
the existing sewer system and for hydraulic model
calibration. Psomas will review sewer basin tributary
areas and land use to determine the appropriate
number and locations of proposed flow monitoring sites.
As part of the preparation of this proposal, Psomas
has already identified the various sewer basins within
the City through review of the system GIS (see exhibit
shown on the following page). From our review of these
basins and land use, Psomas will select preliminary
flow monitoring locations that will be finalized through coordination with City staff and ADS Environmental
CITY OF LOMITA | Sanitary Sewer System Master Plan 14
2 SCOPE OF WORK AND PROJECT APPROACH
Services (ADS), the subconsultant teaming with Psomas
to perform the flow monitoring. Psomas and ADS
have worked together on numerous similar projects.
Recommended flow monitoring locations, duration, and
analysis will be documented in a draft Flow Monitoring
Plan Technical Memorandum, discussed with City staff
in a workshop meeting, and then finalized prior to
directing ADS to install the flow monitoring equipment.
ADS utilizes the best available technologies to provide accurate data collection. The proposed flow monitoring
plan includes collecting flow data at a maximum of 10
sites simultaneously for a period of 14 days. ADS will
obtain encroachment permits (assumed to be a no-fee
permit), install flow monitoring equipment, and provide raw data and a flow monitoring report.
Dry weather data collected will provide essential
information on existing conditions and will be utilized in determining land use loading factors, hydraulic
modeling calibration, and future capacities and
projections. Design criteria developed for dry weather
flow will provide sufficient excess capacity for wet
weather flow conditions.

TASK 5 (OPTIONAL)
DEVELOP GIS-BASED SEWER MODEL
Update GIS of Existing Sewer Infrastructure
Psomas’ GIS team will update the existing GIS of the
City’s sewer infrastructure based on plan research to
include all necessary data for the development of the
GIS-based hydraulic sewer model, specifically, pipeline upstream and downstream invert elevations. It is also
proposed to add the year of construction to aid in
system evaluation. Pipeline diameter, material, and
length are already included in the GIS. The updates will utilize data from an estimated 300 sheets of as-built
plans available from the County in PDF format. Data in
the existing GIS will also be compared against the plans to identify discrepancies. The GIS team will ‘cleanup’
sewer line and manhole point features so that all line
work will snap to manholes with no gaps or overshoots.
The resulting GIS will enable a seamless transition of
all necessary data into the GIS-based sewer modeling
software.
Plan sheets will be linked to the appropriate sewer main pipelines and manholes within the GIS. This will make for convenient future access by the City and CSMD, saving
time involved in digging through numerous large plan

sets online and then locating the appropriate plan sheet within the set.
Sewer Model Development
Psomas will coordinate with City staff on the selection of a GIS-based sewer modeling software. Initial
recommendations are InfoSewer or InfoSWMM
software, by Innovyze, and AquaTwin Sewer software,
by Aquanuity. The selected software will be utilized to create a hydraulic model of the City’s sewer collection system. As a previous master plan model is not
available, an entirely new model will be constructed
using the updated GIS of the City’s sewer system created in the foregoing task.
Data gaps and inconsistencies will be identified
and reviewed against plans and through discussion
with City staff. There are typically survey datum
inconsistencies when elevations are taken from plans
that span across decades, as is the case in the City’s
system. These may be resolved through field survey as
needed and as discussed below as an optional task in
this Scope of Work. The GIS of the sewer system will
maintain and identify the original source of data and
any datum adjustments made to reconcile discrepancies
within the hydraulic model. Model construction and
reconciliation of data will be documented in the Model
Development Technical Memorandum for review and
discussion within a workshop meeting with City staff.
Model Calibration
Psomas will calibrate the hydraulic model to flow
monitoring data collected as part of this Scope of Work.
Collected flow data will be evaluated for both average
flow and diurnal peaking. Psomas will obtain and
review existing land use data in GIS within the City’s
service area from local municipalities and/or through
assessor parcel data available to Psomas online. The
land uses within the tributary basins of each flow
monitoring station will be compiled along with land
use statistics such as acreage and residential density.
Initial flow factors by land use type will be developed based on typical industry standards and planning
criteria. The land use parcel data will be geocoded to an adjacent loading manhole within the hydraulic model
and the resulting modeled flow will be compared to
measured flow monitoring data. Flow into the City’s
sewer collection system from areas located outside the
City will be included and loaded in the model at the
most upstream City manhole. This includes flows from
the City of Torrance to Walnut Street at W. 242nd Place and from Rolling Hills Plaza at 255th Street and 256th
Street, as identified from online maps for the CSMD.
Psomas will develop calibrated flow factors on an
iterative basis, and within typically accepted sewer
generation rates, to calibrate to the observed sewer flow data. The average flow factors established by land use
type will be used within the model, including the areas that were not flow monitored. Peaking curves will also
be generated for residential and non-residential land
uses to calibrate to the observed diurnal flows. A Model Calibration and Flow Factor Technical Memorandum
will be prepared to document the model calibration and
resulting flow factors and diurnal curves. Results will be discussed with City staff in a workshop meeting and
adjustments made, as necessary.
Build-Out Projections
Psomas will collect available planning documents
and collaborate with City staff to develop population
projections and annual growth forecasts to be
consistent with long-range planning. Psomas will
compile and review future County and City Land Use
Map data, General Plan, active and current Specific
Plans and Development Agreements, the Regional
Housing Needs Assessment, and other pertinent data
to develop population projections and buildout land use conditions. The buildout scenario will be incorporated
into the hydraulic model by including flows to account
for the projected growth, development, and infill.
As part of the model calibration, discussed above,
Psomas will analyze observed sewer system flows and
develop sewage flow factors based on the tributary
land use data. Psomas will review and evaluate current
City and County design criteria and flow factors used
in sizing future facilities. Based on this information, design factors and peaking ratios will be developed for future planning along with design criteria. Projected
flows used in the sewer system analysis will be
correlated to population and land use projections and
used to evaluate system capacity and deficiencies under buildout conditions. While buildout conditions will
be used to size recommended capital improvements,
time-phased sewer loading will be considered when
prioritizing these improvements. Buildout conditions,
sewer flow factors, and design criteria will be
documented in a Buildout Condition and Design Criteria

TASK 6 (OPTIONAL)
FIELD SURVEY
A field survey plan will be developed based on the
evaluation of the model and GIS data, data gaps, and
data inconsistencies. In review of the online as-built
plans, it is estimated that plans are available for the majority of the system. An initial estimate of the survey effort is based on a field survey and dipping 10 percent of the City’s manholes, or approximately 100 manholes
as a maximum amount. The survey effort may be
reduced by evaluating the capacity of small upstream
tributary areas using minimum pipeline slopes. This
evaluation and the results will be discussed with City
staff who can then determine if a survey is desired. Rim elevations may be collected at additional manholes to
adjust for datum inconsistencies. In this case, the slopes along pipelines, as provided in the sewer plans, will
be maintained while elevations are adjusted using the
survey data and depth to invert.
Psomas will establish project control using a
combination of fast-static GPS and conventional
survey methods for the area. Horizontal control will be relative to the North American Datum of 1983 (NAD83),
current Epoch, with coordinates based on the California Coordinate System (CCS83, Zone VI). Vertical control
will be based on NAVD88 datum relative to GPS-derived
orthometric heights (Geoid12A).
Psomas will obtain the rim and invert elevation of
all pipes connected to the manhole and attempt to
identify the size and material of each pipe. A drawing
and downhole photo of each manhole will be provided
as part of our deliverables. We estimate that we can
locate and obtain inverts on 15 manholes per working
day. Psomas survey will take the lead on pulling any
required encroachment permit and coordinating
with the City or County (no-fee encroachment permit
assumed).

TASK 7
SEWER SYSTEM CAPACITY EVALUATION
AND RECOMMENDATIONS
Psomas highly recommends hydraulic modeling
(Optional Task 5) to evaluate the capacity of the sewer system under both existing and projected buildout
conditions. Once developed, the model will become a
useful planning tool for the City, not only in this master planning effort, but in years to come.
Psomas will utilize the newly developed and calibrated
hydraulic model to evaluate the capacity and operation
of the City’s existing sewer system facilities under both existing and buildout conditions. System deficiencies
will be identified based on peak flow conditions and
developed capacity criteria.
The hydraulic model will then be used to size future
facilities and develop recommended improvements to
meet the needs of buildout conditions. Improvements
will be prioritized based on a combination of capacity
constraints as well as age and condition. Capacity
improvements will first be prioritized to meet existing deficiencies and then buildout deficiencies based on
anticipated phased development.
Alternative solutions such as diversions to existing
trunk sewers or new connections to the Los Angeles
County Sanitation District system will be developed,
where appropriate, to correct system deficiencies
along with a strategically phased improvement
plan to enhance the reliability of the City’s sewer
system. The preferred and alternative solutions will
consider capacity, condition assessment, construction
constraints, potential institutional and environmental
issues, and cost considerations. Prioritized
improvements will be phased in a 10-year CIP through
2033. Remaining improvements will be developed by
phase in five-year increments to buildout. Results will be documented in a Phased Capital Improvement Plan
Technical Memorandum and reviewed with the City at a
workshop meeting.
If the City elects to exclude model development
and calibration (Optional Task 5) from the Scope
of Work, Psomas will coordinate with the City to
identify pipelines that are more likely to be capacity
deficient based on slope, diameter, tributary area,
and communication with field staff. Flow monitoring
presented in Task 4 (as an optional task) would be
tailored to collect flow data for these identified pipeline reaches. Peak flow depth to pipeline diameter ratios
(d/D) would be calculated for select pipeline reaches
utilizing a Microsoft Excel program that Psomas has
developed.
If the City elects not to include both model development and calibration (Optional Task 5) and flow monitoring
(Optional Task 4) in the Scope of Work, Psomas will
utilize typical flow generation by land use type and
peaking factors to calculate peak flow d/D for select
pipelines based on diameter, slope, and tributary area.
The flow factors selected will be coordinated with
the City. An option would be to utilize LACSD flow
generation factors (typically very conservative or high).
An initial review of the City’s sewer system indicates
areas of focus would include 8-inch pipelines along
Appian Way, Eshelman Avenue, Oak Street, Cypress
Street, and Pennsylvania Avenue due to the large
sewer basins tributary to these systems. Another area
of focus is the 10-inch VCP aligned outside roadways
and through developed properties from Pacific Coast
Highway to Ebony Lane (between and parallel to
Western Avenue and Walnut Street). This pipeline has a
large tributary area and the sewer plans (C.I. No. 1003) are dated 1934. Based on a preliminary review of the
system, it is estimated that approximately 10% of the
pipelines by length will be identified for evaluation.

City of Anaheim, Central Area Sanitary Sewer Master Plan – Anaheim, CA: Project Manager for this major revision to the central portion of the City. A substantial number of sewer capital improvements have been constructed since the previous master plan. Major work efforts include major revisions/upgrades to the City’s sewer GIS flow monitoring, hydraulic modeling, model calibration, development of recommended capital improvements, and a financial implementation plan.
Yorba Linda Water District, 2022 Sewer Master Plan – Yorba Linda, CA:
Project Manager for preparation of Yorba Linda Water District’s (YLWD) 2022 Sewer Master Plan. YLWD nearly doubled its sewer service area since the previous master plan, taking over the eastern portion of the sewer system that was previously under the control of the City of Yorba Linda. The InfoSewer model was updated and expanded for the entire service area of approximately 9,000 acres using the District’s sewer GIS. The update involved extensive sewer flow monitoring for model calibration and determining sewer loading factors by land use type.
Build-out land use projections were used to analyze ultimate conditions.
Adding existing septic systems to the sewer collection system was also evaluated. Existing and build-out model scenarios were used to develop a capital improvement program for the District along with complete documentation of the sewer master plan update. This master plan updated the 2010 Sewer Master Plan prepared by Psomas.
City of Anaheim, Combined East Area Master Plan of Sanitary Sewers and Financial Implementation Plan – Anaheim, CA: Project Manager to prepare a computer-based hydraulic model and master plan report to evaluate the sewer system within the eastern portion of the City of Anaheim, located east of SR-57 and SR-91, to identify sewer system needs for existing and build-out peak dry weather flows (PDWF). This area encompassed approximately 12,658 gross acres (20 square miles) and has an existing population totaling approximately 80,000. This analysis resulted in $711,167 (September 2005 dollars) in recommended capital improvements necessary to correct system deficiencies in the build-out PDWF condition, including existing system improvement costs.

YLWD nearly doubled its sewer service area since the previous master plan, taking over the eastern portion of the sewer system that was previously under the control of the City of Yorba Linda. The InfoSewer model was updated and expanded for the entire service area of approximately 9,000 acres using the District’s sewer GIS. The update involved extensive sewer flow monitoring for model calibration and determining sewer loading factors by land use type.
Build-out land use projections were used to analyze ultimate conditions.
Adding existing septic systems to the sewer collection system was also evaluated. Existing and build-out model scenarios were used to develop a capital improvement program for the District along with complete documentation of the sewer master plan update. This master plan updated the 2010 Sewer Master Plan prepared by Psomas.
City of Anaheim, South Central Anaheim Sewer Study – Anaheim, CA:
Project Engineer for a sewer study within an approximately 1,800-acre area tributary to two major trunk sewer systems along Katella Avenue and Ball Road in the City of Anaheim. The study area encompasses some of the highest flow-generating land uses in the City including the Anaheim Resort, Disneyland, the Platinum Triangle, and portions of Downtown Anaheim. Psomas identified capacity constraints within the system under buildout scenarios during modeling conducted for the Central Area Sanitary Sewer Master Plan. Alternative improvement projects were evaluated by focusing on the diversion of flow to other tributary systems to free up capacity in the constrained major trunk sewers. Alternatives were evaluated based on construction feasibility, planning level construction costs, and the quantity of flow diverted. The most favorable alternatives were then evaluated at the concept design level through utility research with recommended improvements ranked to maximize capacity, limit cost, and provide for continued growth within the study area.

City of Lomita Sanitary Sewer System Master Plan
Scope of Work
Project Understanding
The goal of the project is to collect and review all significant data to complete a targeted Sanitary Sewer System Master Plan, focusing on primary sewer collection pipelines that serve large tributary basins and areas of new development, including three corridors along Lomita Blvd, Narbonne Avenue and Pacific Coast Highway. The Project will develop a sewer hydraulic model for select basins and a capital improvement program (CIP). The estimated duration to complete the Sanitary Sewer System Master Plan is eight (6) months.
To complete this work effort, Psomas proposes the tasks detailed in the following Scope of Work. Our hands-on project management approach, consistent and proactive communication, and established QA/QC procedures will deliver the project on time and within budget.
Project Tasks
Task 1 – General Administration, Meetings, and Presentations Our project manager, Mike Swan, will be the point of contact for the work effort and coordinate all communication with City staff. Psomas will collaborate with City staff through regular progress meetings, Technical Memoranda, and workshops. Psomas will submit monthly progress reports with each invoice. Progress reports will contain work performed, project concerns and impacts, the work remaining, and the work anticipated for the next month.
Project meetings will include the preparation of the agenda, meeting attendance, and meeting minutes for kick-off and up to 6 additional monthly status meetings and progress workshops. Workshops will be held to review milestones and receive City input for scope items, flow monitoring locations and procedures; flow monitoring results and model calibration; capacity evaluation of the existing sewer collection system; and recommended capital improvement projects.
Meeting agendas will be submitted to the City for review two (2) working days prior to each scheduled meeting and workshop. Minutes will be distributed within five (5) working days and include decisions made and action items for all parties.
Task 2 – Review Existing Documents, Data, and Information Psomas will collect and review all pertinent data obtained from the City, Los Angeles County Public Works, and the County Consolidated Sewer Maintenance Division (CSMD) to be used in the preparation of the 2023 Sanitary Sewer System Master Plan. Useful information will include as available, as-built and other sewer plans; CCTV and condition reports; the latest CSMD Sewer System Management Plan (SSMP); site-specific sewer studies and other planning documents; sewer infrastructure data; flow metering records; GIS data; CAD mapping; current operations and maintenance practices; and information collected from communication with City and CSMD staff. Psomas will provide City staff with a Request for Information in Excel format at project kick-off where key staff and due dates will be assigned.
Psomas has conducted an initial review of the City’s sewer infrastructure data and understands the system layout and sewer basins. This review was based on GIS data provided by Los Angeles County Public Works that include pipeline alignment, diameter, and material. Invert elevation and related pipeline slope data is not included in the GIS. As-built plans were also reviewed as available through the LA County Public Works Land Records Information website. Through our initial research and evaluation, it was determined that plans are available for the majority of City’s sewer system. This review found pdf plans for more than 80 percent of the City’s sewer pipelines by length available through the County’s online data. A more thorough review, as part of this project, will likely identify and locate additional plans. Psomas will build on the City’s exiting sewer GIS data, as needed, with data from these as-built plans.
Deliverables:
Request for Information in Excel format to be updated by Psomas as information is received and distributed to the project team.
Assumptions:
City staff will provide requested information, as available, within the scheduled timeframe as determined at project kickoff.

Scope of Work
Task 3 – Existing Sewer Condition Assessment
Review CCTV Inspections and Pipeline Condition Assessment Maira Salcedo, Condition Assessment Lead Engineer, and Benjamin Halbach, Project Engineer, who are both certified by NASSCO under the PACP and MACP programs, will perform a detailed pipeline assessment for strategically identified CCTV-inspected sewer pipe segments assumed to be available from CSMD. Upon initial review of the sewer collection system, we recommend conducting a condition assessment of the 10-inch V.C.P. aligned outside of roadways and through developed properties from Pacific Coast Highway to Ebony Lane (between and parallel to Western Avenue and Walnut Street). This pipeline has a large tributary area and the sewer plans (C.I. No. 1003) are dated 1934. Upon review, Psomas will provide a recommended rehabilitation method along with a justification/rationale for each sewer segment.
The recommendations may consist of complete pipeline and manhole replacement in the same trench; excavation, and performance of point repairs; lining sewer segments in between existing manholes; lining sewer sections; or a combination of methods. Rehabilitation methods will place priority on trenchless repairs to minimize excavation and impacts on the community.
The Master Plan will include the finalized rehabilitation recommendations and exhibits to provide a general visual representation of the recommended repairs .
Task 4 – Develop Flow Monitoring Program, Conduct Field Verification, and Data Collection Psomas will review sewer basin tributary areas and land use to determine the appropriate number and locations of proposed flow monitoring sites. As part of the preparation of this proposal, Psomas has already identified the various sewer basins within the City through review of the system GIS (exhibit shown on the following page). Psomas will coordinate with the City to identify pipelines that are most likely to be capacity deficient based on slope, diameter, tributary area, and communication with field staff. Flow monitoring would be tailored to collect flow data for these identified basins.
Psomas will select preliminary flow monitoring locations that will be finalized through coordination with City staff and ADS Environmental, the subconsultant teaming with Psomas to perform the flow monitoring. Recommended flow monitoring locations, duration, and analysis will be discussed with City staff in a workshop meeting, and then finalized prior to directing ADS to install the flow monitoring equipment.
ADS utilizes the best available technologies to ensure accurate data collection. The proposed flow monitoring plan includes collecting flow data at three (3) sites simultaneously for a period of 14 days. ADS will obtain encroachment permits (assumed to be a no-fee permit), install flow monitoring equipment, and provide raw data and a flow monitoring report.
Deliverables:
ADS Flow Monitoring Report in PDF format with tables, hydrographs, and scattergraphs.
Flow monitoring data in electronic format.
Workshop meeting with City staff to discuss and agree upon Flow Monitoring Plan.
Assumptions:
Flow monitoring does not include wet weather flow analysis. If a significant wet weather event were to be captured during flow monitoring, the costs and benefits of wet weather modeling would be discussed with the City and may be included as an add service.
Any encroachment permit required by the City will be assumed to be issued at no fee since this is a City project. If a fee is required, this can be added to the fee.

Scope of Work
Task 5 – Develop GIS-based Sewer Model of Select Sewer Basins Model Construction
Psomas will coordinate with the City to identify pipelines that are most likely to be capacity deficient based on slope, diameter, tributary area, current and proposed land use, and communication with field staff. These pipelines, and related tributary flows, will be included in a GIS-based hydraulic sewer model. Psomas will update the existing GIS data for modeled pipelines based on plan research, specifically, including pipeline slope (based on upstream and downstream invert elevations and pipeline length). Pipeline diameter, material, and length are already included in the GIS. The updates will utilize data available from the County in PDF format.
Data gaps and inconsistencies will be identified and reviewed against plans and through discussion with City staff. There are typically survey datum inconsistencies when elevations are taken from plans that span across decades, as is the case in the City’s system. The model development process will not attempt to resolve these discrepancies but rather fix the most downstream invert elevation for each sewer basin and develop upstream invert elevations using pipeline slope data from sewer plans. This method will allow for pipeline capacity evaluation without the need for field survey.
Model Calibration
Psomas will calibrate the hydraulic model to flow monitoring data collected as part of this Scope of Work. Collected flow data will be evaluated for both average flow and diurnal peaking. Psomas will obtain and review existing land use data in GIS within the City’s service area from local municipalities and/or through assessor parcel data available to Psomas online. The land uses within the tributary basins of each flow monitoring station will be compiled along with land use statistics such as acreage and residential density. Initial flow factors by land use type will be developed based on typical industry standards and planning criteria. The land use parcel data will be geocoded to an adjacent loading manhole within the hydraulic model and the resulting modeled flow will be compared to measured flow monitoring data. Flow into the City’s sewer collection system from areas located outside of the City will be included and loaded in the model at the most upstream City manhole.
Psomas will develop calibrated flow factors on an iterative basis, and within typically accepted sewer generation rates, to calibrate to the observed sewer flow data. The average flow factors established by land use type will be used within the model, including the areas that were not flow monitored. Peaking curves will also be generated for residential and nonresidential land uses to calibrate to the observed diurnal flows. Results will be discussed with City staff in a workshop meeting and adjustments made, as necessary.
Build-Out Projections
Psomas will collect available planning documents and collaborate with City staff to develop population projections and annual growth forecasts to be consistent with long-range planning. Psomas will compile and review future County and City Land Use Map data, General Plan, active and current Specific Plans and Development Agreements, the Regional Housing Needs Assessment, and other pertinent data to develop population projections and buildout land use conditions.
The buildout scenario will be incorporated into the hydraulic model by including flows to account for the projected growth, development, and infill. Our understanding is that the near future new development will be primarily along three corridors, which is where we will focus our system capacity analysis. These corridors are along Lomita Blvd., Narbonne Avenue, and PCH.
As part of the model calibration, discussed above, Psomas will analyze observed sewer system flows and develop sewage flow factors based on the tributary land use data. Psomas will review and evaluate current City and County design criteria and flow factors used in sizing future facilities. Based on this information, design factors and peaking ratios will be developed for future planning along with design criteria. Projected flows used in the sewer system analysis will be correlated to population and land use projections and used to evaluate system capacity and deficiencies under buildout conditions. Buildout conditions, sewer flow factors, and design criteria will be reviewed with City staff at a workshop meeting.
Deliverables:

City of Lomita Sanitary Sewer System Master Plan
Scope of Work
Workshop meeting with City Staff on model development and calibration.
Assumptions:
City staff will aid in providing available data on development and growth forecasts consistent with long-range planning.
City staff will aid in coordination with the County to obtain projected land use, specific plans, development agreements, and other data for buildout conditions.
Task 7 – Sewer System Capacity Evaluation and Recommendations Psomas recommends hydraulic modeling to evaluate the capacity of the sewer system under both existing and projected buildout conditions. Once developed, the model will become a useful planning tool for the City, not only in this master planning effort, but in years to come. Though this analysis includes a limited number of basins, the model may be expanded in the future to include additional pipelines and basins.
Psomas will utilize the newly developed and calibrated hydraulic model to evaluate the capacity and operation of the modeled sewer system facilities under both existing and buildout conditions. System deficiencies will be identified based on peak flow conditions and developed capacity criteria. If the most upstream reach of a modeled basin is found to be deficient, the model will be extended upstream to identify the extent of deficient pipelines.
The hydraulic model will then be used to size future facilities and develop recommended improvements to meet the needs of buildout conditions. Improvements will be prioritized based on a combination of capacity constraints as well as age and condition. Capacity improvements will first be prioritized to meet existing deficiencies and then buildout deficiencies based on anticipated phased development.
Alternative solutions such as diversions to existing trunk sewers or new connections to the Los Angeles County Sanitation District system will be developed, where appropriate, to correct system deficiencies along with a strategically phased improvement plan to enhance the reliability of the City’s sewer system. Prioritized improvements will be documented in a Phased Capital Improvement Plan Technical Memorandum and reviewed with the City at a workshop meeting.
An initial review of the City’s sewer system indicate areas of focus would include 8-inch pipelines along Eshelman Avenue, Oak Street, Cypress Street, and Pennsylvania Avenue due to the large sewer basins tributary to these systems. Another area of focus is the 10-inch V.C.P. aligned outside of roadways and through developed properties from Pacific Coast Highway to Ebony Lane (between and parallel to Western Avenue and Walnut Street).
Deliverables:
Phased Capital Improvement Plan Technical Memorandum.
Workshop meeting with City Staff on sewer capacity evaluation and recommendations.
Task 8 – Sewer System Master Plan Documentation
Capital Improvement Program (CIP)
The combined analysis of system capacity and condition assessment will be used to develop a prioritized CIP for sewer system infrastructure improvements. A CIP schedule will be developed to prioritize improvements in a 10-year plan through 2033. The CIP will include tables with properly designated names/descriptions, specific locations/facilities, schedule, and estimated costs. For financial planning, the cost estimates will include construction, engineering, and other technical services, contract administration, permitting, and construction management. Any additional improvements, beyond 10 years, will be developed for a build-out condition.
Psomas will coordinate with the City to provide all information necessary to incorporate into the City’s separate Sewer Impact Fee Study.
