DISCUSSION – Continued
In July 2021, following project completion, the City entered into an agreement with the City of Lakewood (AFN 844.1) for post-construction operations, maintenance and monitoring services of the facility. Lakewood initiated and performed monthly maintenance of the facility as well as SCADA monitoring operations, however this was short-lived as Lakewood staff struggled with the operations and maintenance of their own stormwater capture facilities at Bolivar and Mayfair parks. In short, Lakewood did not have the personnel capacity or equipment to provide the maintenance and operations for the Caruthers facility as well as their own stormwater facilities.

Bellflower, along with several other cities experiencing operational issues with the stormwater capture facilities, took these issues and concerns to the Gateway Water Management Authority (GWMA) and requested help in obtaining a list of vendors capable of providing the necessary maintenance and on-going operations needed to run these stormwater facilities. In response, the GWMA authority issued a Request for Qualifications in May 2024 to solicit qualified engineering/contracting firms with stormwater, wastewater or equivalent experience to provide the following services:
1) maintenance and operations; 2) remote control and monitoring of a system (SCADA); and 3) evaluation and assessment of stormwater facilities to optimize their performance.

Following the GWMA’s RFQ process, four firms were identified and listed as qualified lead firms that had the ability to perform the services including Craftwater, GeoSyntec Engineering, Michael Baker International and NV5.

After reviewing the qualifications of the four firms, Public Works staff felt that the Michael Baker International team was best suited to cover the operating issues at the Caruthers facility. Public Works met with representatives from Michael Baker International, provided them with as-built plans for the system and requested a proposal to assess the current condition of the facility including the mechanical equipment, the SCADA system and the condition of the sub-grade chambers. Michael Baker International has submitted a proposal to perform the initial assessment of the Caruthers facility in the amount of $136,220. A copy of the detailed proposal is attached.

CEQA
Pursuant to the California Environmental Quality Act (CEQA) (Public Resources Code §§ 21000, et seq.) and CEQA Guidelines (California Code of Regulations, Title 14, §§ 15000, et seq.), the City conducted an environmental assessment. Based on the environmental assessment, the project was determined to be categorically exempt pursuant to CEQA Guidelines § 15303 (Class 1 – Existing Facilities).

B.Commercial general liability insurance will meet or exceed the requirements of ISO-CGL Form No. CG 00 01 11 85 or 88. The amount of insurance set forth above will be a combined single limit per occurrence for bodily injury, personal injury, and property damage for the policy coverage. Liability policies will be endorsed to name City, its officials, and employees as “additional insureds” under said insurance coverage and to state that such insurance will be deemed “primary” such that any other insurance that may be carried by City will be excess thereto. Such insurance will be on an “occurrence,” not a “claims made,” basis and will not be cancelable or subject to reduction except upon thirty (30) days prior written notice to City.

C. Automobile coverage will be written on ISO Business Auto Coverage Form CA 00 01 06 92, including symbol 1 (Any Auto).

D. CONTRACTOR will furnish to City duly authenticated Certificates of Insurance evidencing maintenance of the insurance required under this Agreement, endorsements as required herein, and such other evidence of insurance or copies of policies as may be reasonably required by City from time to time. Insurance must be placed with insurers with a current A.M.

Best Company Rating equivalent to at least a Rating of “A:VII.” Certificate(s) must reflect that the insurer will provide thirty (30) day notice of any cancellation of coverage. CONTRACTOR will require its insurer to modify such certificates to delete any exculpatory wording stating that failure of the insurer to mail written notice of cancellation imposes no obligation, and to delete the word “endeavor” with regard to any notice provisions.

E.Self-Insured Retention/Deductibles. All policies required by this Agreement must allow CITY, as additional insured, to satisfy the self-insured retention (“SIR”) and 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 is subject to the approval of the City Attorney and the Finance Director. CONSULTANT 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 the CONTRACTOR’s failure or refusal to do so in order 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. -7-

EXHIBIT A
March 25, 2025
Proposal for Assessment of Design, Operations, Maintenance, and Performance of Ruth R.

Caruthers Park Regional Stormwater Capture and Infiltration Project This proposal presents task descriptions and associated costs for Michael Baker International and its subcontractors (collectively Michael Baker) to support the City of Bellflower with an in-depth operational assessment of the Ruth R. Caruthers Park Regional Stormwater Capture and Infiltration Project (Project) which was constructed in 2019-20 and currently has significant operational constraints. The purpose of the assessment will be to:
·Conduct an initial assessment comprising of:
o Summary of existing Project performance data on flows captured and pollutant loading reductions attained during periods of prior operation and at a watershed data collection scale;
o Conduct an initial physical inspection of the underground capture system; ·Evaluate engineering plans to identify potential deficiencies, needed enhancements, and costs. ·Review the operating environment in the Los Angeles County Flood Control District’s (LACFCD) facilities supplying water to the Project;
·Evaluate SCADA monitoring/controls and needed upgrades to inform the City of Bellflower and operators of the Project on system status and remote operability; and ·Compile information into a summary report with a recommended prioritization and phasing of activities along with associated costs for consideration relevant to the City of Bellflower’s maintenance funding.

In completing the assessment Michael Baker will be mindful of the design objectives that call for the elimination of dry weather flows and maximizing wet weather pollutant removal but will temper these expectations with the recognition that funding for operations and maintenance through the Safe Clean Water Program is limited. The five-year cycle of operations and maintenance allocated for this project beginning November 2020 is approximately $150,000 per year. The task elements will utilize existing data and assessments, such as the Craftwater Engineering April 2024 memo, to the extent possible, to streamline and reduce duplication of work.

The assessment does not include cleaning and testing of project facilities and components, since pricing for these elements cannot be generated until the inspections in this proposal are completed. Incidental removal of some accumulated sediment in the underground capture system may, however, be needed to access and photo-document certain Project areas.

Chris Crompton will serve as Program Manager for Michael Baker. Pacific Advanced Civil Engineering, Inc., (PACE), Mladen Buntich Construction Company’s (Buntich), PERC Water Corporation (PERC), and Downstream Services, Inc. (DSI) are team members and will assist Michael Baker in completing this work. -12-

AGENDA ITEM 7 – Statement of Qualifications (SOQ) for Operations, Maintenance and Evaluation of Regional Stormwater Capture and Treatment Projects

SUMMARY

There are currently five (5) regional projects that are complete or are expected to become operational within this calendar year. Operational and maintenance (O&M) issues are of major concern for these projects. Member agencies of the Los Cerritos Channel, Lower Los Angeles River, Lower San Gabriel River and Lower Los Angeles River Upper Reach 2 Watershed Groups requested GWMA to prepare and release a Request for Qualifications (RFQ) to solicit qualified engineering/contracting firms with stormwater, wastewater or equivalent experience to provide the following services: 1) O&M; 2) remote control and monitoring (SCADA); and 3) and/or evaluation of Regional Stormwater Capture and Treatment Projects to optimize performance as well as construction work that may be needed to achieve that optimization. GWMA would not be contracting directly with the teams. Rather, it would share the solicitation package results with the five regional project leads as well as other GWMA member cities and agencies for each of them to directly solicit proposals and enter into contracts with one or more of the qualified team, if they so choose.

DISCUSSION

An RFQ (attached) was officially released on May 1, 2024 and the Statement of Qualifications (SOQ) being due on June 5 , 2024. However, due to the complexity of the required services and questions received from potential RFQ respondents, an ad hoc committee made up of lead agencies in charge of the five regional projects and GWMA staff determined a need to re-write the RFQ was in order. On July 30, 2024, a new RFQ was released and circulated with an SOQ due date of September 16, 2024.

GWMA received four SOQs (attached), each of which was made up of a Lead Firm and a team of sub-consultant/contractors. GWMA’s consultant, John L. Hunter & Associates reviewed the four SOQs and determined that they all met the minimum requirements/criteria set forth in the RFQ (memo attached).

The four team lead firms are as follows:
• Craftwater
• Geosyntec Engineering
• Michael Baker International
• NV5

SUBJECT: Evaluation of 4 Statements of Qualification
RFQ for Operation and Maintenance of Regional Stermwate‘r Projects” JLHA has competed it’s review of the four responding firms:
0 Craftwater,
o Geosyntec,
- Michael Baker International.
- NVS.

Evaluation Summary
All four firms have offices in Southern California and personnel and team members with decades of stormwater knowledge and experience. All the firms have five years of experience within the stormwater field. One firm was formed in 2019, but nonetheless did meet the requisite experience criteria.

Regional Projects that will require Operations and Maintenance with specific applicability to this RFQ have only recently begun to come online and the opportunities for firms to have had actual Operations and Maintenance experience with large regional stormwater projects is limited.

Therefore, the criteria for “experience” were broadly interpreted to include regional projects, sewerage treatment pla nts, stormwater infiltration ponds, large privately owned treatment systems such as those found at General Industrial Permitted sites (ex: airports), etc. All four firms and their subcontractor teams were deemed to meet the criteria of Operation and Maintenance experience with two or more major projects.

The responding firms and their subcontracting teams demonstrated adequate understanding of the, goal of the RFQ and the ability to provide the necessary services. However, while all firms indicated familiarity with SCADA, it was not generally clear if these firms could provide off-site monitoring and control and that, if applicable, should be followed-up on by individual agencies when moving forward to the next phase of any selection process.
in summary, all four responding firms have meet the RFQ Criteria.

RFQ for Operations, Maintenance, and Evaluation of Five (5) Regional Stormwater Capture and Treatment Projects 1

1. Introduction and Summary
The GWMA, a California joint powers authority, on behalf of the member agencies of the Los Cerritos Channel, Lower Los Angeles River, Lower San Gabriel River, Lower Los Angeles River and Upper Reach 2 Watershed Management Groups, is releasing this Request for Qualifications (RFQ) to solicit qualifications from engineering/contracting firms with stormwater, wastewater or equivalent experience.

The purpose of this RFQ is to assist the GWMA member agencies in directly contracting with a qualified firm(s) to provide the following services: 1) Operations and Maintenance, 2) remote control and monitoring (SCADA); and 3) and/or evaluation of Regional Stormwater Capture and Treatment Projects to optimize performance as well as construction work that may be needed to achieve that optimization.

SOQs will be received from firms with stormwater and/or wastewater or equivalent experience.

This RFQ is Step 1 of a two-step selection process. This RFQ process does not include Step 2 as described below.

Step 1: GWMA is requesting qualifications and will conduct an initial screening of submittals received.

Based on the initial screening, GWMA will establish a list of pre-qualified firms. Multi-firm teams will be considered, but the SOQ must be submitted under one lead firm.

Step 2: The list of the pre-qualified firm or firms will be made available to individual GWMA member agencies. Those member agencies with jurisdiction over regional projects may then take a separate action to select pre-qualified firm(s), request specific proposal(s), and negotiate and award contract(s) for requested activities.

2. Background
There are currently five (5) regional projects that are complete or are expected to become operational within this calendar year. These five projects have immediate applicability to this RFQ and are Bolivar Park, Ruth R. Caruthers Park, Mayfair Park, Sub-Basin 4 (located at the Long Beach Airport), and Urban Orchard. An additional twelve (12) regional projects are anticipated to be constructed over the next ten to twelve years and the pre-qualification list may be used by the GWMA member agencies to select firms to assist with operations and maintenance. These projects are Hermosillo Park, El Dorado Park, Furman Park, Spane Park, John Anson Ford Park, Apollo Park, Independence Park, Cerritos Sports Complex, Lynwood City Park, Heartwell Park, Skylinks Golf Course, and Salt Lake Park.

Summaries of recent operations and maintenance work for the five regional projects are attached in Attachment 1. The additional information is being provided to describe the anticipated scope of services which may be requested by GWMA’s member agencies during Phase 2 of this process.

3. STEP 1 – PREQUALIFICATION PROCESS

RFQ for Operations, Maintenance, and Evaluation of Five (5) Regional Stormwater Capture and Treatment Projects 18 c. Anticipated Scope of Service
Note that this project originally had an infiltration component, but the infiltration rates appear to be negligible, and groundwater appears to be entering the storage/infiltration gallery through the bottom and sides of the gallery effectively negating any infiltration of runoff. Similar to the prior three projects, this gallery will be used primarily for settling and storage.

2 Stormwater Flow
Splitter
The Stormwater Flow Splitter
Structure is a rectangular
reinforced concrete vault that is
used to split flows before pre-
treatment. The structure does this
by utilizing a split weir, which
directs stormwater into the two
Jensen Diversion Structure (JDS)
Units for treatment. Once the
water is treated, the stormwater
enters the box again before exiting
through the motor activate sluice
gate into a 60” RCP.

Ms. Madeline Anderson
Gateway Water Management Authority

Paramount, CA 90723
Subject: Statement of Qualifications for Operation, Maintenance, and Evaluation of Regional Stormwater Capture and Treatment Projects

Dear Ms. Anderson:

We are pleased to submit Craftwater Engineering’s (Craftwater) Statement of Qualifications (SOQ) to provide Operation, Maintenance, and Evaluation of Regional Stormwater Capture and Treatment Projects for the Gateway Water Management Authority (GWMA). The engineers at Craftwater are fortunate to have a long history of supporting the GWMA agencies featuring the development of Watershed Management Programs (WMPs), stormwater capture feasibility studies, and the design of some of the most advanced stormwater projects in Southern California.

Craftwater is the leading industry expert with the Safe, Clean Water Program (SCWP). In fact, Craftwater’s personnel led or previously supported the feasibility studies and designs of 63 of the 151 SCWP Infrastructure Program projects submitted since program inception. To date, our SCWP funding applications have had over an 85% success rate, securing over $470 Million from the Safe, Clean Water Infrastructure Program, which includes $320 Million for construction funding. Our team has also successfully supported 5 SCWP Project Modifications that included site modifications and resulted in $37 Million in additional funding. Our SCWP experience has taught us that having secured the design and construction funding for this crucial project will require a design team that has the ability to evaluate site alternatives and optimize the size and performance of this infrastructure in order to implement the best project for the City while meeting key performance metrics.

Our team's demonstrated success through this approach will greatly enhance the City’s ability to also be in the best position for construction funding.

We have assembled the most experienced team of industry-leading experts in stormwater capture design and analysis in California. Our key project team members include Chad Helmle, PE, Principal in Charge, Oliver Galang, PE, Program Manager, and Merrill Taylor, PE, Lead Project Manager. Our carefully selected partners include firms with expertise in regional stormwater capture facility components including Black & Veatch (Operations, Maintenance, SCADA, and construction services), Downstream Services (BMP Cleaning Services), Epic CleanTec (Stormwater Harvesting Systems), FMF Pandion (Monitoring Services), Opti (Active BMP Controls and Optimization), Pre-Con (Pre-Cast storage units and construction services), and Projectline (SCADA controls and operations). Our team has been assembled to provide the GWMA agencies with a full depth of resources for this project.

Should you have any questions, you may contact me at 213-598-4178 or [email protected]. As our company’s Principal, I am the authorized representative for all communication and negotiations concerning this RFQ, I acknowledge by signing this cover letter that all statements are true and correct, and that we received and considered all addenda to the RFQ.

Respectfully submitted,

Oliver Galang, PE | Principal | Craftwater Engineering

1| COMPANY QUALIFICATIONS AND EXPERIENCE
This section provides an overview of the Craftwater
Team (Firm and Subconsultants) and the Experience of
our team. We have assembled a team to provide a full
depth of resources from operation, maintenance,
monitoring, SCADA, and construction services.

1.1 FIRM DESCRIPTION AND STABILITY
Craftwater Engineering,
Inc., established in April
2019 and headquartered in
Southern California, is a California corporation certified Disabled Veteran Owned Business Enterprise (DVBE) and
Micro Business (MB) structured to deliver agile, full-
spectrum service to the stormwater market in California.

In over 5 years, our rapidly growing team of 26
associates, located in Pasadena and San Diego are
skilled at adapting to the continuously evolving
regulatory environment, yet grounded enough to
deliver high quality and readily- constructible designs.

We take pride in programmatic stewardship – avoiding
the pitfalls of changing teams between the planning,
concept, full design, construction, and monitoring
phases of each project. Craftwater is poised to continue to serve the Gateway Watershed Management Authority
(GWMA) by helping to deliver innovative multi-benefit
project designs/bid documents and feasibility studies,
shape practical regional stormwater policy, and
strategically plan investments in green infrastructure and high-end monitoring. We strive to provide meaningful
environmental outcomes with affordable and functional
water infrastructure to California and beyond.

With over 120 years of combined experience in the field of civil engineering, we take pride in the fact that every project manager on our founding team is a licensed
Professional Engineer in the state of California. Our
engineers have identified, envisioned, evaluated
feasibility, designed, and/or contributed to construction oversight for approximately 24 regional stormwater
capture projects within the Los Angeles County area
including but not limited to stormwater capture projects in Lakewood (Bolivar Park and Mayfair Park), Bellflower (Caruthers Park and Simms Park), Duarte (Encanto Park), Downey (Furman Park, Apollo Park, Independence Park),
Lynwood (Lynwood City Park), Long Beach (Heartwell
Parks, Skylinks, and El Dorado Park), Pomona (Fairplex), Paramount (Spane Park and Progress Park), Signal Hill
(Reservoir Park), and Whittier (York Field). We aim to
continue this proven success with the GWMA.

As trusted strategic advisers and designers, our mission is to always act genuinely to advance the best interests of our clients, the environment, and the state of science by designing real solutions for total water cycle
management. Our core services include Watershed
Science, Modeling, and Planning; Stormwater Capture
Feasibility and Design; Operations and Maintenance, and Regulatory and Water Quality Science. Recently
described as “the most well-connected firm in LA,” our
agile team is prepared to leverage our national
relationships and resources to provide the GWMA and its member agencies with unparalleled quality, efficiency,
and a client-centric culture.

PROJECT COST PERCENT PERFORMED
$18.9M 60%

PROJECT SUMMARY
The development of the Spane Park Stormwater Capture Project in the City of Paramount represents a major opportunity to enhance Spane Park within the City and continue the regional scale progress to achieve pollutant load reductions for the Lower LA River Watershed. Craftwater completed a Feasibility Study including the 10% Preliminary Design used to secure $1.5M in funding for the design and $18.9 Million for construction from the Safe, Clean Water Program (SCWP).

Stormwater flows are diverted from a double 10.5’W x 6.5’H RC Box storm drain at a rate of 20 cfs before being pumped to a 54” pipe that is conveyed to an existing 6’ wide bottom trapezoidal channel. Flows are conveyed 1.1 miles downstream to the project site where flows are diverted to a 5.4 ac-ft subsurface storage and treatment system. The facility has been optimized and has the capacity to treat 20.4 AF of stormwater for each storm event.

Our team prepared the Feasibility Study for submission to the SCWP for funding in October 2020. After the City of Paramount received funding, Craftwater was selected to continue to carry the project through final design. The design has progressed to 90% design. Craftwater assisted the City of Paramount with obtaining $18.9 Million in funding for construction under the Safe, Clean Water Program.

PROJECT COST PERCENT PERFORMED
$15.7M 60%

PROJECT SUMMARY
Craftwater Engineering, Inc, is supporting the City of
Bellflower with the development of the City’s next regional stormwater BMP for the Los Cerritos Channel Watershed.

The goal of the project is to help the City comply with bacteria and metals TMDLs, as presented in the Los Cerritos Channel Watershed Management Program while providing
additional benefits of park revitalization. This project will capture discharge from a 758-acre area from the
10’Wx7.5’H RC Box Storm Drain along the west side of the park. The objective of this project is to address the water quality needs, particularly the metals TMDLs. The facility will redirect all dry weather and wet weather runoff from the storm drain through the diversion system and pre-
treatment system to remove trash, debris, and sediment. A drainage pipeline will convey the flows into a large, buried, multi-chambered storage and infiltration facility.

As part of this project, Craftwater Engineers prepared the Project Concept and Feasibility Study that met all criteria for the Safe, Clean Water Program and secured $2.1 Million for design of this facility. Craftwater is also preparing the construction documents to support the construction of this facility. Craftwater also assisted the City with securing $13.7 Million in funding for construction under the Safe, Clean Water Program.

PROJECT DATES

PROJECT COST PERCENT PERFORMED
$11M and $15M 100%

PROJECT SUMMARY
As major steps towards implementing the Los Cerritos
Watershed Management Plan, the Craftwater Team
supported the City of Lakewood with implementing what are considered the first “smart regional stormwater BMPs” in Los Angeles County. The projects consist of air-inflated rubber dam diversion systems to re-direct runoff from both open and underground channels through pre-treatment systems to
remove trash, debris, and sediment. Pump stations and
drainage pipelines convey the pretreated water into large, buried multi-chambered storage/infiltration facilities.

Stormwater collected in the underground reservoir is treated and used to irrigate the park. Excess water at Bolivar Park is infiltrated, while Mayfair Park employs a flow-through
filtration system and an optional diversion to the sanitary sewer. The team modeled the performance of the facilities to demonstrate progress towards compliance, and evaluated the advantages of using smart, real-time controls to optimize system performance. Craftwater Engineers supported the City with the development of the design documents, obtained the LACFCD diversion permits, provided technical support during construction, and prepared the operations and maintenance manuals.
 Craftwater also supported the City with the post-construction performance evaluation, modeling analysis, and developed the stormwater facility retrofit strategy at Bolivar Park for improved access and maintenance.

3| PROJECT UNDERSTANDING AND APPROACH

UNDERSTANDING OF SCOPE
The GWMA is a large watershed-based coalition of cities, water agencies, and a port. The GWMA member agencies
are located in the southeastern area of the Los Angeles County and are responsible for addressing regulatory
compliance under 4 watershed groups for the Lower LA
River Upper Reach 2, Lower Los Angeles River, Lower San Gabriel River, and the Los Cerritos Channel watersheds.

Together, Craftwater engineers (in their capacities at
previous firms) worked closely with these permittees to develop the WMPs as an initial plan to protect the region and stormwater management and to secure interim
compliance with the regional MS4 Permit.

During the years since the WMP development, the
engineers at Craftwater have derived great personal
satisfaction with assisting the agencies within the GWMA and around Los Angeles County with watershed master
planning to identify and prioritize specific projects,
evaluating project feasibility per the SCWP guidelines, and preparing construction bid documents for the
implementation of the most advanced stormwater
capture facilities ever developed in the Los Angeles area.

Some of the first Regional BMPs were designed and
constructed in the GWMA Watersheds by the Craftwater
engineers. Craftwater clearly understands and
internalizes the challenges facing the GWMA because we
have personally and continuously worked with all of the watersheds (LARUR2, Lower LA River, Lower San Gabriel
River, and the Los Cerritos Channel), and our core team members have been active in the watershed for over a
decade. We feel ownership in the success of this group
and have staked our reputation on it.

The GWMA member agencies seek the assistance of
experts in regional stormwater capture facilities to
provide Operations and Maintenance, SCADA controls
and monitoring, and evaluation services of Regional
Stormwater Capture and Treatment Projects to optimize
performance as well as construction work that may be
required to optimize the facility or enhance the
operations and enable maintenance access of these
facilities.

HISTORY WITH THE 5 REGIONAL PROJECTS
Craftwater Engineers have supported the GWMA member
agencies with the implementation of the five regional
projects. Also, our team has been directly supporting the GWMA member agencies with the initial assessment of 4
of the 5 regional projects at Bolivar, Caruthers, Mayfair, and Sub-Basin 4 (Long Beach Airport). In addition,
Craftwater Engineers were involved at the early stages of analysis and sizing of the Urban Orchard Project.

HISTORY WITH THE ADDITIONAL REGIONAL

PROJECTS
Craftwater Engineers have also been integral with the
development of all the regional projects that are
anticipated to be constructed by the GWMA member
Our team developed tools to evaluate the operational
infiltration rates and recommended optimization strategies for the Bolivar Park BMP treatment facility

agencies. In fact, Craftwater is the only firm that can claim to have prepared all the Safe, Clean Water
Program feasibility studies that were the basis for
Hermosillo Park, El Dorado Regional, Furman Park,
Simms Park, Spane Park, John Anson Ford Park, Apollo
Park, Independence Park, Cerritos Sports Complex,
Lynwood City Park, Heartwell Parks (Palo Verde and
Clark Channels), Skylinks Golf Course, and Salt Lake Park.

In addition, Craftwater is leading the design and
successfully secured construction funding under the Safe, Clean Water Program for Furman Park, Simms Park, Spane
Park, and Lynwood City Park.

APPROACH TO SERVICE CATEGORIES
The Craftwater Team’s experience with BMP operations,
monitoring, and maintenance dates back to 2000 with
early studies with Caltrans in the Los Angeles region that have guided the direction of many BMPs currently
implemented regionally and nationally. Our
understanding of BMP effectiveness is not only rooted in direct monitoring experience, but also based on a long
history of BMP engineering, analysis, and design. In the past ten years, our Team members have designed more
regional and green infrastructure projects in Southern
California than any other group. Because of our Team’s in- depth engineering knowledge of BMPs, along with
extensive monitoring experience, we offer a unique
perspective on the “operability and performance” of
BMPs to properly evaluate their effectiveness.

Specifically, our comprehensive Team has led the design and monitoring plans for more Safe, Clean Water
Program-funded projects than any other firm, so we are
able to incorporate monitoring early in the design phases; we avoid overlooking key access points within the BMP to collect accurate flow data and representative samples.

TASK 1. OPERATION AND MAINTENANCE
(O&M)
The Craftwater Team has been assembled to provide for
O&M of the various facilities in accordance with the
established O&M Manuals for each facility.

Craftwater will review the facility-specific Operations and Maintenance (O&M) Plans for each of the existing
Regional Stormwater Capture and Treatment Projects,
inspection and system maintenance activities are
conducted regularly. Beginning with regular inspections to determine whether the system is properly functioning, and operating as designed, sediment and trash
accumulation is documented. Inspection reports identify and document all potential problems and inform
maintenance activities. Our Team’s continuous approach
to the Operation and Maintenance, Monitoring, and
Optimization of stormwater BMPs ensures through our
efforts that each municipality is receiving the most value possible from your operating assets. This requires a focus on frequent inspections, thorough documentation and
reporting, and timely deployment of the cleaning and
vactor equipment.

Craftwater’s Services include the following team
members.
• Craftwater’s Project Management Team. Our
project management team will be responsible for
the overall management of these facilities. We
will assign an individual Project Manager who will
be responsible for the overall operations and
maintenance of each facility.
• Black & Veatch will conduct an evaluation of the
O&M Plans and establish the maintenance
schedules.
• Downstream Services will provide routine
cleaning of stormwater infrastructure including
the rubber dam and diversion structures, pumps,
valves, removing sediment and trash from
structures.
• Black & Veatch, Projectline, and FMF Pandion
will provide services for the testing and

calibration of monitoring equipment, SCADA
control systems, and other electrical equipment.
• Access to LACFCD Channel. Since each project
has an establish LACFCD Use and Maintenance
Agreement, our team will coordinate with the
local LACFCD Maintenance Yard when accessing
the channel/storm drain for maintenance.
• Sanitation Districts of LA County. The Mayfair
Park Project has a discharge option to the sanitary
sewer. The status of the discharge permit will be
reviewed by Craftwater to ensure that the
coordination (including SCADA access) is
established with the Sanitation Districts.
• Stormwater Harvesting Units and the LA County
Public Health. In order to use the stormwater
harvesting facility, the Sampling Plan must be
followed as required by the Cross Connection
Permits for the use of stormwater as irrigation
water at Bolivar, Caruthers, and Mayfair. Our
team includes Epic CleanTec, who provides
operation and maintenance services for these
systems.

Confined space entry is required at several facilities to maintain and clean these assets. Necessary protocols for work around open-access structures and confined spaces
will be strictly followed per OSHA standards, regulations, and procedures for work in confined spaces.

Considerations for Operation and Maintenance
The following summarizes our strategies that we’ll bring to each Regional Project:
• Data collection during operation and
maintenance of key assets including regional
stormwater capture and water quality treatment
systems, low-flow diversion dams, pre-treatment
systems, trash capture devices, and all associated
monitoring equipment.
• Stormwater Harvesting Systems. Leverage our
detailed knowledge of the existing site conditions
as well as innovative technologies that support
effective water quality treatment and
downstream impact mitigation such as complex
water harvesting treatment systems. For
example, our review of the Wahaso systems at
Bolivar, Caruthers, and Mayfair determined that
the waste stream needs from the system should
not be returned to the storage reservoir.
• Monitoring System evaluation. Craftwater will
review the monitoring data from each SCADA to
determine the operational status of the various
sensors (water level, flow, and turbidity). Our
SCADA systems team includes scientists and
engineers that will support the GWMA agencies
with setting up systems to provide access and
enable real time evaluation.
• Stormwater Infrastructure. Several Projects are
equipped with controls such as valves, inflatable
dams, pumps, flowmeters, and sensors. The
water harvesting systems are equipped with a
wide variety of smaller filters and sensors as well.

Our Team provides the expertise in operating and
maintaining all of the equipment fitted in each
Project location. This includes troubleshooting
and programing logic controllers (PLCs).

Craftwater’s review of the infrastructure
determined the following priorities to enhance
the maintainability of these facilities.
o Pre-Treatment Systems. The potential for
overflow and bypass of flows and sediments
will affect the long-term use of the subsurface
storage structure and sustainability of
infiltration.

The Craftwater team worked closely with the LA
County Public Health to approve the first stormwater
capture facility permitted for spray irrigation use

GATEWAY WATER MANAGEMENT AUTHORITY
Operation, Maintenance, and Evaluation of Regional Stormwater Capture and Treatment Projects Section 3 –Approach & Understanding Page 3-4

o Access for Maintenance. Access for the
vactor trucks and for personnel is necessary
to ensure the facility will continue to function.

TASK 2. SCADA SYSTEMS
Our team will review the existing SCADA systems that
have been implemented at each of the projects to
allow for remote monitoring and control of these
projects. Craftwater will utilize the services of
Projectline to assist with the management of these
projects. Craftwater also has included Opti to our
team to provide for active controls, optimization, and
multi-project management of the GWMA facilities.

The Opti approach integrates the rainfall forecast to
improve the systemwide management of the GWMA
Facilities. The potential to integrate Opti for the
GWMA can be evaluated and allow for the GWMA to
oversee all of these facilities simultaneously as well.

Regional stormwater capture project performance
is driven by the amount of water the system
receives (inflow), the volumetric capacity (storage),
and the method of treating and draining the tank
(outflow). Each of these three variables—inflow,
storage, and outflow—are interrelated and the
adjustment of one will directly change how the other
two perform (e.g., restricting the inflow rate is
equivalent to “sucking through a straw” and will limit
the amount of pollutants an otherwise large storage
tank may have access to treat; conversely, an
undersized storage tank is rapidly overwhelmed by
an overdesigned inflow diversion and may fill too
soon without capturing the dirtiest peak of the
storm). Our experience has proven that it is essential
to evaluate these three parameters simultaneously
when looking at the design and performance of a
regional practice. The model can evaluate select
pollutants or volume, giving the design team the best
combination for maximizing performance and
multiple benefits. A strategic deployment of
environmental sensor technology is crucial to enable
an adequate assessment of the infrastructure’s
performance in the future.

TASK 3. ENGINEERING AND TECHNICAL

SERVICES
Craftwater’s team of design engineers are available
to assist the GWMA agencies with development
system improvements to further enhance the
operations and maintenance of these Projects or to
enhance the water quality benefits. Craftwater led
the assessment of the Los Cerritos Channel Regional
BMPs, which include Bolivar Park, Caruthers Park,
Mayfair Park, and Sub-Basin 4 Projects.

Craftwater’s design team will develop design
drawings that can be used to install facility access
improvements, such as subsurface storage access
shaft, trash screens, or trash bypass deflector devices for the pre-treatment units. In addition, water
quality benefits can be improved at Bolivar Park and
Caruthers Park with the addition of a post-treatment
filtration unit coupled with the existing discharge
pumps.

Members of the Craftwater Team developed and led
some of the inaugural BMP monitoring programs in
California over 20 years ago for Caltrans and continue
to implement monitoring programs in Los Angeles
County. Our team was recently hired to support the
County with development of program- and BMP-
Craftwater Engineers led the development of the most
innovative stormwater capture facilities in the GWMA.

Mayfair Park SW Capture Project incorporated
pretreatment, filtration discharge, and sanitary sewer
discharge for optimal system performance.

level monitoring strategies to evaluate Safe, Clean
Water Program success. The outcomes of Craftwater
engineers’ contributions to this project will help to
establish state-of-the-science protocols for new BMP
monitoring efforts.

In addition, our team has been responsible for the
feasibility analyses of 73 projects across California
including 56 submitted to the Safe, Clean Water Program Infrastructure Program, more than any other team in the region. Craftwater Engineers developed a monitoring
plan for each of these feasibility studies in order to
evaluate the pre-construction and post-construction/long term performance of regional structural BMPs. For
Adventure Park, our engineers managed the pre-
construction monitoring of Sorensen Drain. This involved obtaining the LACFCD access permit and approval of the
sampling equipment. The pre-construction water
quality data from the Sorensen Drain was used as
the basis for design optimization and for the sanitary
sewer diversion requirements.

TASK 4. CONSTRUCTION/REPAIR SERVICES
Our team includes the following subconsultants to
assist the GWMA Agencies with construction and
repair needs for diversion structures, pumps, valves,
and access to underground structures.
• Downstream Services. Standard or routine
repairs of equipment, screens, etc. will be
provided by Downstream Services.
• Black & Veatch which is an Engineering and
Construction Firm. This firm has the
capability to implement larger more complex
repairs, retrofits, and construction for these
projects. We will utilize this firm if the
installation of a small pump station or
filtration unit may be required.
• Pre-Con is a manufacturer of pre-cast
concrete structures and also a construction
contractor. Craftwater has recommended
that the subsurface storage structures at
Bolivar, Caruthers, and Mayfair could be
retrofitted with additional access shaft to
improve the ability to maintain these
structures.

The Craftwater Team will provide technical design
support and construction/repair services for the
GWMA.

President and Chief Executive Officer

Résumé 1
Experience Summary
As President of Craftwater Engineering, Inc, Mr. Helmle offers national experience with a focus on the Southern California water resources service area. He has overseen hundreds of large and small water resources projects and has served as program manager or principal-in-charge of several of the largest municipal on-call stormwater-focused contracts in the country. His responsibilities in these roles has afforded him the unique opportunity to explore a broad spectrum of stormwater-related issues, ranging from strategic planning to design and implementation. Examples of his project leadership include numerous green infrastructure master planning efforts, over 100 regional-scale green infrastructure retrofit design or pre-design projects, and ground-breaking watershed and BMP modeling analyses.

He is especially passionate about finding innovative solutions to the challenging prospect of retrofitting existing urban landscapes and infrastructure to meet the compliance, water resiliency, and/or runoff management needs of municipal agencies. He continually pushes the envelope to improve his team’s methods by inventing new processes, templates, and tools for creating effective and robust design concepts and modeling approaches for stormwater capture projects. This constant push for new approaches has yielded several key innovations, such as incorporating real-time control elements to boost BMP performance while meeting the integrated needs of watershed managers. As a former Air Force civil engineering officer, Mr. Helmle has brought the lessons learned to bear by developing cost-effective concepts for municipalities and numerous military installations alike, resulting in cost savings that spans into billions of dollars. Mr. Helmle strives to strike the ideal balance between form, function, and simplicity of operation.

Relevant Experience
As-needed Stormwater Engineering and Consulting Services, City of San Diego. Program Manager for a $25M, 5-year as-needed contract (2018 – 2019) and a $21.5M, 5-year as- needed contract (2014 – 2018) to provide the full spectrum of stormwater program support to the City, including all of the City’s Water Quality Improvement Plans, stormwater capital project design, special scientific studies, BMP research and development, compliance reporting, and general permit support. Managed one of the largest stormwater contracts of its kind, helping the City gain attention on a national stage, especially with regard to cutting- edge BMP master planning, stormwater design, and innovative permit compliance strategies. Managed over 100 task orders worth nearly $30 million. Signature projects completed as part of this contract include: (1) a comprehensive watershed master plan that utilized first-of-their-kind modeling approaches to strategically identify and prioritize regional and green infrastructure project opportunities; (2) an innovative regional stormwater harvesting analysis that demonstrated the degree to which local stormwater capture can feasibly and realistically augment water supplies by upwards of 25%; and (3) regionally- critical re-negotiation of bacteria TMDL requirements that will set the stage for reducing municipal bacteria mitigation requirements across the state.

Watershed Engineering On-Call Contract, County of Los Angeles. Principal in Charge for $6M, 3-year as-needed contract to support the county with wide-ranging watershed services, including the design of regional BMPs in parks, regional master planning work, and piloting of innovative regional stormwater capture programs. Work for the County was recognized at the national and regional level as precedent-setting, especially in terms of applying technical innovation to solve emerging stormwater problems. Signature projects that Mr. Helmle has personally led include (1) the Multi-Agency Collaborative Stormcatcher Project, which demonstrated the feasibility of leveraging parcel-based real time control systems to capture runoff and augment water supplies; (2) the Lower Los Angeles River Revitalization Plan, which emphasizes a watershed-based approach to revitalizing a 19-mile long, two-mile wide reach of the LA River corridor; and (3) multiple park-based regional stormwater capture BMP designs intended to meet pressing TMDL compliance needs.

Résumé Chad S. Helmle, PE
2 Support for the City and County of San Francisco’s MS4 Permit Implementation, San Francisco Public Utilities Commission (SFPUC).

Principal in Charge. Provided contract and technical oversight for a task order-based contract to provide technical support to the SFPUC Regulatory Compliance Division over a 5-year period by developing program components for compliance with each element of the 2013 Phase II Permit. Streamlined program management and met required milestones through a combination of program evaluation and planning, establishment of program priorities, development of standard operating procedures (SOPs), development of outreach and training materials, creation or revisions to tracking systems and databases, and other activities to improve the efficiency and effectiveness of the MS4 program.

Chollas Creek Watershed Master Plan, City of San Diego, San Diego, CA. Project Manager for first dynamic, web-based Watershed Master Plan within the City of San Diego that build off of the recommendations made by the approved Water Quality Improvement Plans (WQIPs) and identify project-by-project priorities that will contribute towards compliance with the MS4 permit and TMDLs. Based on a ground-breaking watershed modeling framework, the project provided a comprehensive and adaptive plan containing specific projects and identified synergies with other programs (i.e., CIPs, flood control, hydromodification, stream restoration), and eliminated the inefficiencies of incremental and opportunistic project conceptualization.

Master Plan of Drainage, City of Huntington Beach, CA. Project Manager for the Master Plan of Drainage (MPD), including updating storm drain geospatial data, rapid development and execution of hydrology and hydraulics (H&H) models, assessment of system deficiencies, and prioritization of proposed improvements. Modeling was completed using customized PCSWMM models that account for the low-lying topography within the watershed, as well as pump station boundary conditions.

Strategic Green Street Implementation Plan, Dominguez Channel Watershed Management Group, 2/2017-12/2018. Principal-in- charge of developing a watershed-wide, strategic 5-year green street plan for the 80-square-mile Dominguez Channel Watershed (the most impervious watershed in the Los Angeles Basin). Implemented a novel programmatic framework to efficiently identify and prioritize street-scale project opportunities throughout the watershed. Led team to apply state-of-the-science understanding of green infrastructure to customizing green street configurations to specific environmental conditions and pollutants of concern. Facilitated coordination between nine permittees to incorporate institutional preferences and synergies into prioritization of green street configurations and locations. Ensured clear communication of results using an interactive web-based mapping application to streamline multi-agency review and data transfer with city engineers/scientists/planners, and to enable transparency with regulators/non-governmental organizations.

Green Infrastructure Master Plan, City of San Diego, CA. Project Manager to create a green infrastructure master plan for a 7-square mile pilot area in the City of San Diego. While the WQIPs established well-documented water quality goals and identified specific stormwater capture targets for each individual subwatershed, they lacked the high-resolution data needed to identify specific project needs. This master planning effort leverages a number of key innovations to create new datasets that allow for the identification of specific project opportunities, quantification of their potential costs and water quality improvement, and prioritizes them based on their potential for synergy with other existing infrastructure programs in the City. This project will redefine what constitutes a green infrastructure opportunity by outlining specific project characteristics, evaluating strict feasibility criteria, and taking advantage of cost- saving techniques such as linking related projects and integrating real time controls. Ultimately, the output of this project provides a project-by-project master strategy for achieving compliance while focusing on high-efficiency projects first and leaving the low-efficiency projects for the end.

Cottonwood Creek Watershed LID Retrofit Plan, City of Encinitas – Project Manager. Collaborated with the City to develop a cutting- edge plan for the strategic implementation of green infrastructure to improve storm water quality and reduce the impacts of frequent flooding in the watershed. The approach involved engineering and modeling analyses to provide and a robust technical foundation for the study and a strong public outreach and training campaign designed to communicate the plan to the public and generate support.

A comprehensive summary of watershed conditions characterized pollutant loading issues, locates nuisance flooding areas, and identifies feasible locations for green infrastructure retrofits. A model was developed to establish a baseline condition and further GIS and field investigations are performed to narrow the list of retrofit possibilities to a shorter list of high-potential sites. Ultimately, this information was loaded into a SUSTAIN model that used a cost-optimization routine to identify the lowest cost series of green infrastructure retrofits necessary to meet the water quality and flood control objectives required. Once the optimization results were complete, the candidate projects were prioritized and conceptual designs and cost estimates were developed for the highest priority sites and incorporated into public outreach programs and training seminars.

Pilot Green Infrastructure Project Prioritization System, City of San Diego, CA. Project Manager to develop a pilot-scale green infrastructure project prioritization system to allow the City’s to make data-driven project decisions in an easily accessible and understandable platform. The system includes three key elements: (1) Using LiDAR data and advanced image processing algorithms, GIS layers of green infrastructure opportunities and their associated tributary drainage areas were developed with greater than 95% accuracy; (2) High-resolution data were linked to the City’s watershed modeling systems, and a series of “rules” were developed to prioritize each individual candidate project by its effectiveness and efficiency relative to other projects; (3) A web-based platform was developed to allow users to easily access and explore the data, enabling users to examine different prioritization scenarios across programs, such as LID on public land, green streets, and regional projects. The project prioritization system gives the City the ability to generate an “optimized” CIP that includes cross-program synergy and quantifies the potential cost savings that might result from coordination between programs.

3 achieving compliance for development projects while also resolving nuisance flooding in affected areas. The project approach involves a comprehensive field survey and model analysis to investigate individual flooding areas and reconnaissance-level surveys to identify candidate locations for LID and green infrastructure in the flooding drainage area. A SUSTAIN model is used to evaluate green infrastructure scenarios to identify the lowest cost solution that achieves the flood mitigation and development-related stormwater management objectives. Ultimately, the results of the green infrastructure optimization analysis are incorporated into a green infrastructure planning and sizing tool and conceptual BMP plans are integrated into the final Green Infrastructure Master Plan. This is a first-of-its kind multi-objective approach to be used at an AFB and is expected to pave the way for similar cost-saving efforts at other installations where nuisance flooding is present.

Project Manager to quantify at the planning-level the potential water supply benefits and challenges of capturing treated effluent from green infrastructure to offset potable water supply. Given the billions of dollars of investment needed to capture stormwater to meet water quality goals in the San Diego area, this analysis evaluates the possible cross-connection between the yet-to-be-constructed stormwater capture infrastructure and the existing (and soon-to-be- upgraded) water reclamation infrastructure. Innovative new approaches are being evaluated to determine whether or not such a cross connection is feasible and cost-effective. Several metrics are being developed to support this analysis, such as unit water supply augmentation costs and quantification of water resiliency and risk. The results of this study will set the stage for a potentially unprecedented distributed stormwater capture and water supply augmentation system.

2 Skylinks Golf Course Stormwater Capture Project Design– Long Beach, CA (2021) Providing project management to design a multi-beneficial regional stormwater capture practice at Skylinks Golf Course in Long Beach,CA.

The project is anticipated to divert stormwater from the existing Wardlow Channel to a 9.7-acre-foot underground infiltration storage system set adjacent to an existing golf course. Dry and wet weather flows will flow through the underground storage and be pumped to a surface wetland basin that is placed above the subsurface storage system. Excess stormwater will overflow and be treated by an additional filtration system before returning to the storm drain. Walking paths around the wetland cells, a sand volleyball court for the adjacent Fire Station, and a nursery for the Golf Course are additional project amenities that have been identified while working with project stakeholders.

El Dorado Park Regional Stormwater Capture Project Design– Long Beach, CA (2021) Providing project management to design a multi-beneficial regional stormwater capture practice at El Dorado Park in Long Beach,CA. The project is anticipated to divert stormwater from the existing Artesia Norwalk Channel to a 13.9-acre-foot underground wetland system set in a currently underutilized area within El Dorado Regional Park. The storm diversion will utilize existing storm drain pipes and ditches to convey diverted runoff to the proposed wetland area which is approximately 1.5 miles away from the channel. Dry and wet weather flows will be treated by a proprietary pretreatment device before flowing through the wetland basin that is comprised of multiple cells and planted with native vegetation selected in collaboration with the El Dorado Park staff. Excess flows will go to an existing drainage ditch before outletting downstream at Coyote Creek. The project is also considering discharging some outflow to the sanitary sewer as the Long Beach Water Reclamation path is just south of the site.

Arboretum Natural Treatment Project Feasibility Study– Arcadia, CA (2020) Designed 10% conceptual drawings and prepared Feasibility Study for a regional stormwater capture project submission to the Safe, Clean Water Program for funding. The project includes a stormwater drop-inlet diversion from the LACFCD Arcadia Wash Channel and a 4 acre-feet treatment wetland/recharge basin.

A Pre-treatment unit will remove pollutants from runoff diverted from the Palo Verde Chanel runoff before the water is temporarily stored in a 20 ac-ft subsurface storage system. Treated outflow from the underground storage will travel through a small existing lake where it will offset the need for potable water to sustain the lake’s water level. Wetland cells will enhance the aesthetics of the lake and a naturalized stream will connect the lake overflow back to the existing channel.

Apollo Park Stormwater Capture Project Feasibility Study– Downey, CA (2021) Managed design of 10% conceptual drawings and Feasibility Study for a regional stormwater capture project submission to the Safe, Clean Water Program for funding. The project includes a stormwater diversion from an existing LACFCD storm drain to a 10 acre-feet infiltration system beneath an existing baseball surface. New catch basins and storm drain are proposed at nearby intersections and will connect to the system and help alleviate local flooding. Reductions of impervious area, a green street, permeable pavement, and diverse natural landscaping provide onsite stormwater management and improve the aesthetics of the park.

Griffith Park Stormwater Capture Project Technical Research Proposal – Los Angeles, CA (2021) Prepared Technical Research Proposal for a regional stormwater capture project for submission to the Safe, Clean Water Program for funding.

The project included working directly with the non-profit group, Friends of Griffith Park. A stormwater diversion from an existing City storm drain to a 3 acre-feet storage system beneath an existing park area is proposed. Water collected in the subsurface storage system will be pumped up the site to help feed an existing creek that travels down through the site and supports a diverse ecosystem of plants and animals. Built up debris and sediment will be removed form portions of the creek to allow for the water to flow freely and native plants will replace non-native ones with a focus on water-efficient drought tolerant plants.

Heartwell Park at Palo Verde Stormwater Capture Project Feasibility Study – Long Beach, CA (2020) Designed 10% conceptual drawings for a regional stormwater capture practice adjacent to the Palo Verde Channel for submission to the Safe, Clean Water Program. A Pre-treatment unit will remove pollutants from runoff diverted from the Palo Verde Chanel runoff before the water is temporarily stored in a 7.5 ac-ft subsurface storage system. Outflow from the underground storage will either go back to the existing channel or an existing sanitary sewer in Palo Verde Ave depending on the time of day and the flow rate. Additionally, a surface biofiltration basin will manage dry weather flows and provide a visual to the community of stormwater treatment practices.

City of Pasadena Storm Drain Master Plan and Watershed Assessment – Pasadena, CA (2021) The project attempts to provide a comprehensive inventory of storm drain asset locations/conditions and conduct a watershed assessment to produce an EWMP implementation strategy for the City.

3 provided technical guidance on interpretations and upgrade recommendations. Utilized planimetric data generated from LIDAR and aerial photos to identify and assess parcels in the City that had regional stormwater project potential. Factors considered included parcel owner, tributary area, parcel size, upstream impervious percentage and proximity to an existing drain line.

Santa Fe Drive Bike and Pedestrian Improvements – Encinitas, CA (2021) Prepared conceptual stormwater plans for proposed green street improvements to Santa Fe Drive in Encinitas, CA. Available space for stormwater treatment is limited in the tight roadway corridor, therefore different treatment approaches are proposed such as pre-cast subsurface biolfiltration units located beneath pavement and surface biofiltration located within landscape islands where available.

Underdrains are required due to high groundwater but limited existing drain infrastructure to connect to requires careful selection of treatment cell locations to minimize additional infrastructure costs.

PUMPING | LOS ANGELES, CA
LA Sanitation

Reference: Gordon Haines, Environmental Affairs Officer, (213) 485-0585, [email protected]

The Temescal Canyon Park Stormwater BMP
project diverts runoff from the Temescal Canyon
storm drain to improve overall water quality at Temescal Canyon / Will Rogers State Beach and to help comply with the Santa Monica Bay Beaches Bacteria TMDL for coliform bacteria. Phase 1 of the Project was designed and constructed in 2011 to divert runoff through pre-treatment to a below-ground storage tank discharging to the sanitary sewer system flowing to the Hyperion Water Reclamation Plant. Phase 2 was designed and constructed in 2017 to treat the water in the storage tank for future park irrigation and included a chlorination treatment system and ancillary building. Since the completion of Phase 2, the system has not been operable. In 2019, LASAN tasked Geosyntec to review project design and components to determine how and where adjustments could be made to improve and restore functionality.

Geosyntec prepared a memorandum detailing the
project's optimization adjustment recommendations.

Of the adjustments recommended, based on scope,
schedule, and budget, LASAN and the Geosyntec
Team prioritized two primary improvements. The first
was installing a slide gate on the diversion structure
inlet pipe to add a capability to shut off flows,
especially persistent dry-weather flows, as part of
O&M procedures to perform inspections and
maintenance for the storage tank safely. Second,
based on hydraulic analysis, it was determined that the existing discharge pumps were oversized for the existing sanitary sewer pipe size, which caused flooding at the park due to backflows. The existing storage tank discharge pumps were replaced with correctly sized smaller pumps, including directly connecting the pump discharge lines to the effluent outlet pipe to create a force main that discharges into the sanitary sewer system. Additionally, two combination air and vacuum valves were installed along the force main to exhaust and admit air when discharging. The Geosyntec Team, including MMC (subcontractor), completed the design and construction of these activities in December 2022.

With the optimization updates completed in December 2022, Phase 1 of the Project can be operated in two ways: Option 1 – as a dry weather low-flow diversion. Option 2 – as a stormwater capture and diversion basin, capable of capturing up to 1.25 MG of runoff per storm event and diverting average 5-10 MG of runoff annually.

4 LAX NCOS STORMWATER PUMP STATION
REHABILITATION | LOS ANGELES, CA
Los Angeles World Airports (LAWA)

Reference: Rosa Brice, PE, CM, Senior Airport Engineer I, (310) 957-7173, [email protected]

The Los Angeles World Airports (LAWA) commissioned
the North Central Outfall Sewer (NCOS) Connection
Project (Project) in November 2019 at LAX, connecting the Imperial Retention Basin to the Hyperion Water Reclamation Plant (HWRP) for stormwater discharges. The Project included the installation of a pump well with three 150 HP pumps that would discharge stormwater from the basin to HWRP. Since its initial commissioning, the Project has not functioned according to its design and has not met the facility’s Industrial Wastewater Permit discharge requirements. LAWA hired Geosyntec Consultants (Geosyntec) in July 2023 to investigate various system failures and identify solutions to restore the functionality of the Project and meet Industrial Wastewater Permit requirements to discharge to HWRP.

Geosyntec performed a series of site investigations to
assess the field conditions of the Project, including
pre-storm, storm, and post-storm events. During
investigations, Geosyntec found submerged electrical
equipment, pump failure due to high moisture,
programming errors, inoperable float switches, and
pressure transducer, missing air release valve, issues
with the existing flow meter, and an inoperable gas
detector. Investigations suggested that the existing
location of equipment and pump operations caused
the submergence of electrical equipment. Geosyntec also coordinated the permit-required confined space entry of a vortex manhole to assess the functionality of a gas detector and recommended relocation of the gas detector for ease of access for future inspection and maintenance.

Geosyntec, via a subcontractor, oversaw and managed the installation of a new pressure transducer and float switches for the pumps and reprogramming of the Programmable Logic Controller to run the pumps in automation at temporary set points while the Project is under additional investigation and repairs. The automation was tested and functioning as intended during a storm event, with programming correctly detecting lead/lag pump sequencing, manual overrides, and pump failure. Geosyntec is currently coordinating the pump repairs through a subcontractor and pump manufacturer and providing long-term recommendations for reinstallation, including cable protection and relocation of junction boxes.

From Notice-to-Proceed in July 2023, Geosyntec successfully got the pump system running in automation for use during the 2023-2024 wet season with one of the three pumps while the other two pumps are being repaired. System automation relieved LAWA personnel from manually operating the pumps during storm events.

5 SAN FERNANDO VALLEY GREEN

STORMWATER INFRASTRUCTURE
PROGRAM | LOS ANGELES, CA
LA Sanitation

Reference: Kevin Ho, PE, Civil Engineer, (415) 515-1545, [email protected]

Los Angeles Sanitation (LASAN) implemented a
green stormwater infrastructure program via
alternative project delivery (design-build) in the
San Fernando Valley Basin of Los Angeles to
capture and infiltrate stormwater runoff and
thereby increase groundwater replenishment,
improve downstream receiving water quality of the
Los Angeles River, and reduce localized flooding.

This program consisted of seven project areas in the San Fernando Valley and is expected to capture and infiltrate over an average of 457 acre-feet per year of stormwater runoff from 594 acres of tributary drainage areas through the implementation of drywell systems, storm drain diversions, rain gardens, and catch basins.

Geosyntec provided comprehensive alternative project delivery (design-build) services as a prime contractor to design, permit, construct, monitor, and maintain green street infrastructure over seven different project locations. Geosyntec's scope of services included the development of feasibility studies for similar green stormwater
infrastructure programs in other parts of the City,
implementation of the Small Business Incubator
Program aimed to develop and expand participation
of small business contractors, public outreach,
concept development, preliminary and final design,
permitting and approvals, construction (at risk) and
construction management, and 1 year of monitoring
and maintenance.

This program completed construction in June 2021, installing over 63 drywell systems with pretreatment systems and catch basins, 6 storm drain diversions, 18 rain gardens, and 3 landscaped stormwater medians. Geosyntec also completed 1 year of monitoring and maintenance of the program elements to evaluate performance and operations & maintenance procedures.

Geosyntec completed the design, outreach, permitting, and construction substantial completion in just 17 months of schedule for this $16.8M program. As part of this program, Geosyntec also implemented a Small Business Incubator Program to engage, develop, and expand the pool of local small business contractors to participate in this program as well as other future green stormwater infrastructure projects. Finally, the total change order for this program was zero ($0).

6 PROPOSITION O PROJECTS

OPTIMIZATION, PHASE II
LA Sanitation
Reference: Gordon Haines, Environmental
Affairs Officer, (213) 485-0585,
[email protected]

In November of 2004, the City of Los
Angeles passed Proposition O (Prop O),
which authorized the City to issue a series
of general obligation bonds for up to $500
million for projects intended to improve the
water quality and reduce the volume
and/or rate of stormwater entering the
City’s surface waters. Beginning in 2014, Los Angeles Sanitation (LASAN) initiated optimization for a selection of completed Prop O projects with the goals of increasing project resiliency in order to achieve applicable water quality targets and reduce long-term operation and maintenance costs. Eleven projects were selected for optimization as part of the Phase I Prop O Project Optimization effort, and Phase II of the Prop O Project Optimization effort was initiated in 2017, focusing on eight different projects.

Geosyntec was selected to manage the Phase II
optimization contract, which included optimizing eight
of the City’s Proposition O-funded projects. The
scope of work included five main tasks in addition to
overall project management: 1) Confirmation of each
project’s intent and site conditions; 2) BMP
monitoring during both dry and wet conditions; 3)
Project optimization; 4) Reporting; and 5)
Development of operations management manuals
for use by the City operators at each project. In line with these tasks, Geosyntec first reviewed construction contract design plans and specifications, operations and maintenance manuals, and relevant watershed hydrology and water quality information to confirm project design intent with respect to performance. Geosyntec conducted numerous site inspections and monitored BMP performance, including management of data collected by BMP flow meters and water quality sampling, which informed the recommendations for each project in the Monitoring Plan and the preparation of the Annual and Wet-Weather Performance Reports. Geosyntec also prepared Operations Management Manuals for each project, which include Standard Operating Procedures and Field Guides to be utilized by maintenance personnel.

Geosyntec successfully managed more than ten subconsultants to complete the scope of work within budget and on task. The resulting optimized performance of the Prop O Phase II projects is essential for delivering the intended design outcomes. The quantification and reporting of BMP performance at each project has been instrumental for the City in demonstrating achievement of water quality improvement targets and estimating the volume of captured runoff infiltrated for water supply augmentation.

15 APPROACH AND UNDERSTANDING

STORMWATER EXPERTISE
Geosyntec’s Southern California operations have been
providing surface water and stormwater technical
solutions to clients for almost 35 years; Geosyntec
currently maintains a staff of approximately 250 full-time employees in 11 offices in Southern California, allowing us to provide the bench strength that GWMA and its
member agencies may need on a project-specific basis.

Geosyntec’s engineers and scientists are technical
leaders in stormwater management.

Geosyntec’s comprehensive background in local
stormwater infrastructure planning, design,
permitting, regulatory compliance, construction,
monitoring, and maintenance is unique. Our
extensive experience in each of these areas will be
leveraged to:
• Tackle complex issues and problems
• Recommend and implement cost-effective
solutions for long-term success
• Navigate ever-evolving regulatory compliance requirements • Optimize systems for increased reliability, better performance, and reduced maintenance • Understand and see the “big picture” for operations and maintenance (e.g., water quality drivers, regional planning efforts for infrastructure and O&M resources, standardization of practices, materials, and equipment, etc.)

PROJECT MANAGEMENT AND STAFFING
Geosyntec will assign a project manager and appropriate technical leads and subcontractors for each project depending on the project scope (e.g., O&M, engineering design, permitting, etc.).

We have a deep bench of experienced project managers and technical leads. Our selected project managers have relevant technical backgrounds and excel in communications, project coordination, and scope, budget, and schedule management. Our selected technical leads are senior personnel with demonstrated expertise and will lead the delivery of relevant scope while working with the selected project manager. All fieldwork, including O&M and construction, will be implemented by our subcontractors and supervised by qualified Geosyntec personnel. Field reports will be generated for each day of fieldwork.

HEALTH & SAFETY
Health and safety are an absolute priority for all fieldwork. Geosyntec will develop and implement a Health & Safety Plan (HASP) and conduct Task Hazard Analysis (THA) for all fieldwork for each project. In addition, our standard health and safety practices include the following:

Geosyntec re-evaluated hydraulic design, re-sized
and replaced discharge pumps, and modified
discharge configuration to optimize stormwater

16 • Review and incorporate health and safety requirements from the Owner. • Geosyntec requires all subcontractors to be in good standing for health and safety records. Subcontractor health and safety records are reviewed every year for compliance.
• Require subcontractors to implement their own HASP consistent with Geosyntec’s HASP. • Require appropriate training and qualifications (e.g., confined space entry) where applicable.
• Conduct daily tailgate health and safety meetings.
• Conduct routine safety site visits and audits by the Geosyntec health and safety manager.

OPERATIONS AND MAINTENANCE (O&M)
Having delivered similar projects in various capacities, Geosyntec is intimately familiar with the anticipated O&M elements, which may include the following:
• Sediment and trash removal
• Custom and packaged treatment
systems (e.g., Wahaso Rainwater
Harvesting)
• Pumps, valves, and pipes
• Instrumentation, including sensors,
monitors, switches, gauges, alarms, etc.
• SCADA (Supervisory Control and Data
Acquisition) and PLC (Programmable
Logic Controller) programming and
controls systems
• Electrical equipment (e.g., motor control
centers, variable frequency drives,
switchboards, etc.)
• Other O&M improvements, including
access, lighting, ventilation, and security
• O&M inspections and database
Our O&M approach is a continuous loop process that involves routine inspections and maintenance, evaluation and implementation of improvements with approval by the Owner, analysis and validation of performance, and updates to the O&M program. In the long term, our approach will increase reliability, enhance performance and safety, reduce regulatory risks, and reduce O&M burdens.

SCADA AND INSTRUMENTATION
Geosyntec routinely designs and works with process mechanical systems involving complex instrumentation in treatment and pumping systems. As part of this effort, we routinely work with SCADA and PLC programming contractors during systems testing, start-up, and commissioning phases. More importantly, our team understands the fundamental connection between design intent and control systems. As such, we have a deep understanding when it comes to diagnosing Inspections &
Maintenance
Adjustments &
Improvements
Performance
Validation
O&M Update
Geosyntec’s O&M approach includes continuous feedback

17 and troubleshooting system issues (e.g., design
flaws vs defective construction/equipment vs
illogical programming).

Our key subcontractor, Inframark, specializes
in and has been providing advanced
automation and intelligence solutions through
SCADA for over 560 water and wastewater
agencies. Their capabilities include:
• SCADA and PLC design, installation,
commissioning, and programming
• Control panel manufacturing
• Hosted (off-site) SCADA
• Remove proactive monitoring
• Data analysis and customized data dashboards
• Applied machine learning

ENGINEERING AND TECHNICAL SERVICES
Because we have over 250 professional staff in Southern California, Geosyntec will be ready to respond to most engineering and technical service requests, including emergency responses, promptly with in-house and local personnel. Geosyntec’s in-house engineering capabilities include civil, geotechnical, environmental, mechanical, process, structural, instrumentation, and electrical engineering, and we have been providing engineering and technical services to many of the municipal, regional, state, and utility agencies throughout California for decades. Specifically, our local stormwater engineering and technical expertise include:
• Feasibility studies and grant funding applications (e.g., Safe Clean Water Program) • Stormwater and watershed master planning
• Hydrology and hydraulics analysis
Geosyntec investigated, troubleshoot, and updated PLC
programming to restore automation and partial capacity
for a 50-cfs stormwater pump station at LAX Airport.

• Geotechnical investigations
• Preliminary design reports
• Plans, specifications, and estimates
• Scheduling
• Environmental and construction approvals and permits
• Construction bid phase support
• Construction management, administration, and inspections • Post-construction inspections and monitoring
• Regulatory compliance and reporting

CONSTRUCTION AND REPAIR
Geosyntec carries a California General Contractor license and has been actively implementing design-build projects as the prime contractor (we carry the “contract”). Because of our experience and capabilities in project delivery, we streamline the implementation of construction, big and small, and
repair work for our clients. While
Geosyntec does not self-perform
construction work, we partner with
preferred subcontractors to perform
work, and we maintain full control of
the subcontractor work through
subcontracting, coordination, and
oversight.

We can successfully oversee and
deliver construction projects as the
design-builder because 1) many of
our local professionals have a
background in construction as
general contractors and/or as
construction managers, and 2) we
maintain long-standing relationships
with high-caliber subcontractors. This
brings about some key benefits to the client:
• Design integrity is maintained throughout the construction because we are responsible for construction oversight and field quality control.
• There is less risk for the client because a single entity is responsible for design, construction, and warranty.
• There is a single point of contact for the client throughout the entirety of the design, construction, and post-construction phases for any issues (e.g., performance). • There are potentially significant savings in schedule and administrative costs if there is no separate procurement of construction contractors.

Geosyntec designed and substantially constructed over $17M of green stormwater infrastructure, including over 60 drywells, for the City of LA in just 18 months. Geosyntec also provided 1 year of performance monitoring and maintenance for the built green stormwater infrastructure. -129-
