Cover Letter/Executive Summary
Proposal for the Preparation of Plans, Specifications, and Estimates (PS&Es) for the Rosewood Park Expansion Project (RFP No. 26-1003)
Dear Shahid,
During his tenure as a Los Angeles County Public Works (LACPW) Watershed Manager, CWE Principal and your Technical Advisor and Quality Assurance/Quality Control (QA/QC) Manager Vik Bapna managed the County of Los Angeles Sun Valley Park Water Quality and Groundwater Recharge project, which directed stormwater into the ground to recharge instead of allowing it to drain to the ocean. While some County officials disagreed with this experimental approach, claiming desalination was a more logical future alternative, Vik adamantly went against the grain and became an early proponent of this demonstration project. Working with nature rather than against it led the way to what is now an accepted, effective, and burgeoning practice countywide. The Sun Valley Park Water Quality and Groundwater Recharge project ended up receiving the United States Environmental Protection Agency (USEPA) Environmental Award for Outstanding Achievement and the Institute for Sustainable Infrastructure Envision™ Platinum Award.
What does this have to do with the City of Commerce (City) and your need for upgrade and enhancements to Rosewood Park? The fact of the matter is, you will have a plethora of civil engineering consultants at your beck and call to provide final Plans, Specifications, and Estimates (PS&Es) for this project. CWE is no exception to this, as we have developed pre-design, design, and construction documents for over 60 park projects and green spaces throughout Los Angeles County since Vik and Jason Pereira co-founded CWE in 2006. But large firm names alone don’t have the professional skills to complete the project – their people do. And the CWE difference is Vik and Jason sought to only hire tenacious engineers who will also challenge the status quo if they think they can figure out a better solution; not just passable solutions, but solutions worthy of local and national recognition.
In addition to developing cost-conscious PS&Es, CWE staff has pioneered the design of over 200 multi-benefit stormwater enhancement projects and continue to lead this niche sector with first-of-their-kind projects, especially when it comes to utilizing park facilities for these efforts.
CWE’s San Fernando Regional Park project serves a 950-acre drainage area and recharges groundwater sources, and received the American Society of Civil Engineers (ASCE) Metropolitan Los Angeles Branch (MLAB) Outstanding Parks and Recreation Award. Our City of Santa Ana King Street Urban Greening Project, which removed existing impermeable surface to make way for drought-tolerant landscaping, shade trees, pervious pavement bicycle path, energy-conserving lighting, interpretive signage, seating, Americans with Disabilities Act (ADA) improvements, stormwater bioretention and infiltration systems, waste receptacles, and public art was recognized by the American Public Works Association (APWA) for stormwater quality, the ASCE for Outstanding Environmental Engineering, the California Stormwater Quality Association (CASQA) for Outstanding Stormwater Capture and Use. Our City of Torrance Stormwater Basin and Treatment Wetlands Enhancement project, which involved designing infiltration basins and pressured piping, received seven awards from the ASCE, APWA, Engineering News-Record (ENR), and CASQA for stormwater quality and outstanding Best Management Practice (BMP) implementation.
You deserve a firm with a deep understanding of what it takes to provide thorough, innovative design services that have the capacity to deliver multiple benefits to the Commerce community. We look forward to the opportunity to establish a solid working relationship with you and welcome the chance to discuss our qualifications further. Addendum 1, released May 27, 2026 and Addendum 2, released June 2, 2026 have been incorporated into this proposal. This proposal will remain valid for ninety (90) days from the date of this cover letter. Project Manager Nan Jia, PE, QSD/P, QISP will serve as the primary point of contact for the City and will be responsible for managing the services outlined in the Scope of Work. As Principal, I am authorized to contractually bind the firm and can be contacted at our office located at the address and fax number on this letterhead, by phone at (714) 310-1071, or by email [email protected].
Respectfully submitted,

APPROACH AND SCOPE OF WORK
Understanding
CWE understands that the City of Commerce (City) is planning the Rosewood Park Expansion Project (Project), which anticipates expanding the existing Rosewood Project into a nearby vacant lot and abandoned railroad spur, connecting the existing Rosewood Park with Eastern Avenue and Jillson Street. The proposed improvements may include but are not limited to Americans with Disabilities Act (ADA) compliant walking paths, landscaping, lighting, pickle ball courts, pump track, and other supporting park amenities.
CWE recently assisted the City to pursue grant funding under the 2026 Urban Greening Grant Program, and developed a site concept plan based on grant funding requirements.
In addition, CWE has been assisting Los Angeles River Upper Reach 2 Watershed Management Area (LAR UR2 WMA), which the City is a participating member of, in developing and implementing the Watershed Management Program (WMP). Rosewood Park
was identified as a potential opportunity to capture and infiltrate stormwater runoff from a 1,064-acre catchment area. DDI 23 runs along the westerly edge of the parking lot and will provide for a great opportunity to route portion of the wet-weather runoff to meet the Total Maximum Daily Loads (TMDLs) associated with the City upstream landuses. CWE will partner with the City to explore potentials for incorporating stormwater capture and treatment features to meet Urban Greening Grant Program needs, and also pollutant reduction goals set forth in the WMP.
CWE has led the civil design of many park improvements throughout Los Angeles County. CWE is currently assisting County of Los Angeles Department of Parks and Recreation (LACDPR) in
designing two (2) pickleball courts. In addition, CWE designed civil and stormwater improvements as part of the Barnes Park Multi-Benefit Project for the City of Baldwin Park, which is currently under construction. The Barnes Park improvements include almost full park reconstruction to include upgraded amenities, such as playgrounds, basketball courts, dog park area, site paving, parking lot expansions, and more.
CWE has a long-term working relationships with our partner Terracon Consultants, Inc. (Terracon), JC Chang & Associates (JCCA), and MIG, who will help deliver the Project scope. CWE will leverage its previous experience and history with the City to assist in designing the park expansion to provide additional recreational opportunities, urban greening, enhanced connectivity, and other community benefits.
Scope of Work
Task 1: Pre-Design/Site Investigation Phase
Task 1.1: Project Management and Meetings
Project administration includes staff chartering, project coordination and management, management of subconsultants, and schedule and budget tracking. Project administration efforts are critical for allowing the Project to be completed on time and within budget. CWE will proactively engage the City with timely and concise communications and anticipates feedback at various stages of Project development.
Open and result-driven communications will allow the Project to move forward in a productive and timely manner. We will conduct and participate in the following Project meetings:
¾ In-person kickoff meeting (agree on overall approach, review scope, confirm deliverables, discuss schedule, obtain data, and understand expectations)
¾ Bi-weekly coordination meetings to discuss progress and deliverables (26 virtual meetings anticipated)
¾ Attend and support up to two (2) City Council meetings and one (1) Parks and Recreation Commission meeting, including presentation development, attendance, and presenting at the meetings (these could include meetings where design plans are being accepted or following the bid phase)
We will prepare an agenda prior to each meeting. The agenda will serve as the basis for the meeting summary, which will be prepared shortly after the meeting. We will also maintain a table of action items, which will include key dates and responsibilities. We will develop and maintain the Project schedule, which could be updated as often as monthly for discussion at the monthly meetings. We will show the schedule’s critical path and will include submissions to permitting agencies.
Deliverables:
¾ Agenda, sign-in sheet, and meeting summary for up to 31 meetings, including kickoff, bi-weekly, and utility coordination meetings. ¾ Meeting attendance and presentations in PowerPoint format for up to two (2) City Council meetings and one (1) Parks and Recreation Commission meeting.
¾ Project schedule and budget updates (as often as monthly) in electronic (PDF) format.
Task 1.2: Geotechnical Evaluation
Two borings will be extended to a depth of 15 feet unless auger refusal is encountered prior to full boring advancement. If auger refusal is encountered within 10 feet, an offset boring attempt will be performed to assess refusal materials. Test samples will be collected during drilling in general accordance with the appropriate American Society for Testing and Materials (ASTM) methods. Standard Penetration Testing (SPT) and sampling using standard split-spoon or Modified California samplers will be performed at approximately 5-foot intervals to the maximum depths drilled. Bulk samples will be collected for the upper soils encountered in each boring. In addition, we will observe and record Creating a Better Tomorrow, Today® 3
groundwater levels (if encountered) during and after drilling. Once the samples have been collected and classified in the field, they will be placed in appropriate sample containers for transport to the laboratory.
The CWE team understands the Los Angeles Department of Public Health (LADPH) requires a drilling permit for borings exceeding 10 feet in depth or entering groundwater. We will obtain this permit prior to drilling and the associated fees are included in our fee proposal. The drilling work will be per Work Area Traffic Control Handbook (WATCH) and no additional drilling permits or traffic control plans will be required to perform our geotechnical exploration.
Deliverables: Draft and final Geotechnical Reports in electronic (PDF) format.
Task 1.3: Environmental Site Assessment (ESA) and
Compliance
Task 1.3.1: Base Phase I ESA Services
The ESA will be performed consistent with the procedures included in ASTM E1527-21, Standard Practice for Environmental Site Assessments: Phase I Environmental Assessment Process. The purpose of this ESA is to assist the City in developing information to identify Recognized Environmental Conditions (RECs) in connection with the site as reflected by the scope of this proposal. The potential for vapor migration will be addressed as part of a Phase I ESA and will be considered in evaluation of RECs associated with the site.
There are emerging contaminants that are not identified as a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) hazardous substance by the United States Environmental Protection Agency (USEPA) and therefore not included within the scope of E1527-21. One of these is a family of compounds known as per- and polyfluoroalkyl substances (PFAS) which are a significant contaminant of concern due to their mobility and longevity in the environment. Therefore at this point we have excluded the assessment of PFAS, and can include it if the City desires for additional compensation to CWE.
CWE does not intend to review the preliminary title reports and will not include review of potential environmental lien and Activity and Use Limitation (AUL) restrictions that may be recorded. ASTM and USEPA guidance define obtaining land title and lien records to identify whether any environmental liens or activity land use restrictions have been recorded on the property as a User (client) responsibility. However, the City may delegate this effort, if it desires, to CWE for additional compensation.
Deliverables: Phase I ESA Report in PDF format will be provided.
Task 1.3.2: Phase II Site Assessment
As this is unknown task and will depend on the findings of Phase I ESA, the scope of Phase II will need to be defined based on the number of boring, depths, and analytical samples that will need to be analyzed. As part of the completion of the Task 1.3.1 CWE will develop a scope for the Phase II site assessment and develop remediation plans for the construction phase of the project. This phase will include scope related to coordination with appropriate regulatory agencies (e.g., Department of Toxic Substances Control [DTSC], Regional Water Quality Control Board [RWQCB], South Coast Air Quality Management District [SCAQMD]), as applicable; preparation of remediation plans; and providing cost considerations and design implications associated with remediation efforts.
Deliverables: Phase II Site Assessment and implementation steps.
Task 1.4: Utility Search
CWE will conduct a utility search for the Project site to identify existing or planned future utility conflicts within the Project area. We will prepare and distribute Preliminary Utility Search notices to companies that own utilities in the Project area, which we will determine using our proprietary access to DigAlert records. Based on an initial DigAlert search, we identified 11 utility owners within the Project area, excluding City-owned utilities. We will work with the City to put utility notices on City-letterhead, which reduces fees associated with obtaining plans from utility owners. CWE will maintain a complete record log of utility contacts and responses and provide a copy of correspondence to the City upon request. We anticipate that through the full utility search, we will locate utilities within the public right-of-way. We assume the City will provide as-builts associated with the park to identify utilities outside the public right-of-way, along with as-builts for City-owned utilities. We will draw utilities based on information collected, which will serve as a base map on the design plans.
CWE will send out First and Final Utility Notices, which include design plans, to utility companies for which there may be conflicts, such that those utility owners are given the opportunity to review and comment on the proposed improvements. Our goal is to avoid and/or minimize utility conflicts. We have included utility potholing as an optional task, as it would be beneficial near the diversions.
Deliverables: Preliminary, First, and Final utility notices with hard copies of the plans (utility log available upon request).
Task 1.5: Title Reports and Topographic Survey
CWE will obtain four (4) title reports for the site namely APNs 6335-25- 910, 6335-25-911, 6335-25-907, and 6335-25-902 from First American Title. Based on our preliminary review, the site shows to be 34 feet in width going towards Eastern, and 20 feet wide along the existing parking lot.
CWE will perform a topographic survey within the Project area, which will be prepared in AutoCAD format and serve as the Project base map. CWE will research County and City record data for centerline, right-of-way, easements, survey control, existing geodetic control, and design network plans. We will establish horizontal and vertical survey control based on the City’s Global Positioning System (GPS) network.
Existing monuments will be used to establish the centerline of street alignments. Centerline monuments and ties will be displayed in the topographic survey. Topography will be georeferenced using the North American Datum from 1983 (NAD83), California Zone V for horizontal control and North American Vertical Datum from 1988 (NAVD 88) for vertical control.
The topographic survey will include, but is not limited to, surface features and will dip manholes for storm drain and sewer within the Project area.
Deliverables: Topographic survey will be utilized as part of the final design; therefore, there are no direct deliverables.
Task 2: Plans, Specifications, and Estimate
(PS&E) Phase Services
Task 2.1: Conceptual Plans
Up to three (3) conceptual plans will be prepared for the City’s review and consideration, incorporating the findings from site access, utility impacts, topographic features, and more. The conceptual plans may include, but are not limited to the following features:
Creating a Better Tomorrow, Today® 4
¾ Pickleball courts
¾ Pump track
¾ ADA-compliant walking/riding paths and circulation improvements ¾ Landscaping, irrigation, and site furnishing
¾ Lighting and safety/security features
¾ Potential stormwater features (included in one option only) Deliverables: Up to three (3) conceptual plans in electronic (PDF) format.
Task 2.2: PS&Es
Three (3) conceptual plans developed under Task 2.1 will be reviewed by the City. One preferred concept will be selected to advance into the design phase.
We will prepare 24-inch by 36-inch construction plans in AutoCAD format using a scale of 1-inch equals 20 feet. The different plan sheet types that are anticipated as part of this Project are identified below.
The plan sheets for bidding and construction will be stamped by a registered Professional Engineer (PE) in the State of California.
The following plan sheets are anticipated as part of this Project. We anticipate the complete plan set will include up to 25 sheets.
The conceptual plans may include, but are not limited to the following features:
¾ Title page
¾ General notes and discipline notes
¾ Demolition
¾ Improvement/site plan
¾ Construction details
¾ Boring logs
¾ Pickleball court and pump track
¾ Electrical
¾ Erosion control
¾ Landscape and irrigation
The major Project components are identified below with additional information pertaining to the design. Each of the components will be designed with Operations and Maintenance (O&M) in mind. The elements we design will consider ease of maintenance and we will work with the City’s maintenance team to identify any concerns they may foresee. We will also discuss O&M capabilities early on so we can design components that can easily be maintained by the City.
The plans will include the City’s title block, which we assume will be provided at the start of the Project. The final design plans will include a professional seal, certificate number, registration classification, and expiration date of a licensed Professional Engineer responsible for the preparation of the plans. The final plans will be stamped and signed.
Plans will be submitted at 50%, 90%, and 100%. Comments received will be incorporated in the subsequent submittal and a response to comments will be used to document comments received from the City. Once the 90% PS&Es have been reviewed by the City, utility companies, and other stakeholders as appropriate, CWE will finalize the design package in preparation for construction. The plans will be finalized and used to update the quantities/cost and specifications.
The final plans will be provided in digital format (PDF) stamped, and signed for the City’s use and records. We will also include a copy (PDF) of the technical specification and bid schedule.
CWE will prepare specifications for the Project based on the latest edition of the American Public Works Association (APWA) Greenbook adopted by the City. Special provisions will be used to edit Greenbook sections; however, if necessary, Caltrans standard specifications may be used. We assume the contract documents, such as the notice inviting bidders, instructions to bidders, proposal (bid) pages, and contract pages will be prepared/provided by the City. Special provisions (including technical specifications), along with associated appendices necessary to convey design intent (including geotechnical report, standard plans, etc.) will be provided by the CWE Team.
CWE will obtain boilerplate specifications from the City along with the front-end requirements (Part 1 of the Greenbook). The specifications will clearly list the submittals required from the selected construction contractor.
Deliverables:
¾ 50%, 90%, and 100% plans in electronic (PDF) format, and Response to Comments from the previous submittal phase. ¾ Specifications in electronic (PDF) format for the 50% (table of contents), 75%, 90%, and 100% design phases.
¾ Cost opinions with 50%, 90%, and 100% design phases.
Task 2.3: Mitigated Negative Declaration (MND)
CWE will prepare an MND for the Project in accordance with the California Environmental Quality Act (CEQA) on behalf of the City. Components of this effort will include completion of required studies, preparation of an Initial Study (IS), compilation of mailing lists provided by the City (property owners and interested parties), review of public comments, preparation of a mitigation monitoring and reporting program, and preparation of a Notice of Determination (NOD).
The City of Commerce will be the lead agency. The IS/MND will be prepared per CEQA Sections 15063 and 15070. The Project document will be based on the premise that future land use will not be changed from the current condition and that population, traffic, long-term air, or local environmental impacts are not expected to be negatively altered by the Project. The primary changed condition will be use of existing space to be converted to open space.
The presence of endangered or threatened species, or cultural resources are not anticipated due to the developed nature of the current environment in which the Project will be built.
To evaluate the potential impacts, we will take the following steps:
¾ Complete a literature and database review of the Project vicinity to determine if there is the potential for the presence of cultural resources, specifically in compliance with the requirements associated with Assembly Bill 52 (AB 52), Native Americans.
¾ Consult with the appropriate resource agencies and entities regarding information they may have regarding cultural
resources.
¾ Complete the project description to a level of detail that allows for the evaluation of short-term impacts during construction and long-term impacts after project completion.
Creating a Better Tomorrow, Today® 5
¾ Complete the IS checklist used by the City. Describe the mitigation measures to mitigate short-term impacts during construction, which are anticipated to consist of using Tier III construction equipment, limiting operating hours to standard business hours, complying with the local stormwater runoff controls, and other standard construction impact mitigation measures. Mitigation for longterm impacts is not anticipated. ¾ Complete the NOD for the City of Commerce to certify the project as a MND.
The MND will be circulated for public review and CWE will respond to comments received prior to the City of Commerce’s Council taking action on the MND. CWE will prepare the NOD upon City Council approval for recordation with the County Clerk. We will prepare the original documentation and one (1) revision and then finalize the document for review. All filing fees will be paid by the City.
Deliverables: Draft and final IS, MND, and NOD in electronic (PDF) format.
Task 3: Bidding Phase Services
CWE will support the City during the bid process by responding to questions on the design plans and technical specifications by preparing responses that will be included in addenda issued by the City during the bid phase. CWE will also attend the pre-bid meeting prior to the submission of bids to help present Project information and respond to questions.
Deliverables:
¾ Up to one (1) pre-bid meeting
¾ Request for Information (RFI)/addenda responses (if needed) in electronic (PDF) format.
Task 4: Construction Phase Services
We understand construction funding has not been secured for this Project at this time, so construction support services will be completed based on our hourly rates, adjusted by the Consumer Price Index (CPI). We typically recommend the City approve construction support costs when the construction contract is approved, as this allows us to refine the scope to include what is necessary based on the specifications. We can discuss this option with the City prior to Project award. The scopes below documents potential scope items related to construction engineering support. CWE is also able to provide construction management services if the City prefers.
Task 4.1: Bi-Weekly Construction Meeting
We have assumed the project construction to take approximately nine (9) months. CWE has scoped to attend bi-weekly virtual construction meetings. We assume the Contractor will lead the meetings. We will attend when there are topics of discussion that require quick coordination and engineer input. We assumed attendance at up to 20 virtual meetings.
Task 4.2: Construction Phase Support
CWE will support the City’s construction manager as noted below:
Support Element Assumptions/Description
Pre-construction meeting
CWE will attend a pre-construction meeting with the City’s team and selected Contractor to discuss the Project, schedule, workflow, and more. We assume the meeting will be led by others, while we will provide technical support and will be available to answer Contractor questions. CWE will review and approve shop drawings submitted by contractor as per the PS&E package prior to construction initiation.
Respond to RFIs
CWE will respond to up to 20 RFIs and/or change orders submitted by the Contractor during construction.
We can use a City-provided template or our own internal version. We will respond to RFIs quickly (in accordance with the timelines indicated in the specifications).
Submittal review
CWE will review up to 20 submittals, including the review of shop and working drawings. We typically review technical submittals related to engineering, while the City or their team typically reviews other items that tend to be more City specific. We will develop a list of anticipated submittals for inclusion in the specifications and will respond quickly based on the timeline indicated in the specifications. As with the RFIs, we will use a City-provided template for responses or we can use our own internal template.
Project walk-throughs and
punchlist preparation
CWE will attend/conduct up to one (1) project walk-throughs during and after construction completion.
Punch lists will be prepared.
As-built preparation CWE will prepare as-built drawings based on redlines provided by the Contractor following construction.
We will update the drawings and submit drawing files electronically to the City.
Creating a Better Tomorrow, Today® 6
Deliverables:
¾ RFI responses, submittal reviews, and change order reviews in electronic (PDF) format (assumed quantities are detailed above). ¾ As-built drawings in electronic (AutoCAD and PDF) format.
Task O: Optional Tasks
This optional scope is to ensure if the City would pursue a stormwater management system underneath the trail and a potential stub out for future implementation of a system within the parking area of Rosewood Park to meet the WMP requirements. This also provides for other items that may be needed and were not requested by the City under the Request for Proposals (RFP).
Optional Task O.1: Utility Potholing
Potholing can be performed to better understand the depth of utilities within the Project area that will be crossed. We can provide a refined scope and fee based on the number and depth of potholes that would be beneficial to the Project. Potholing can also be performed by the Contractor as part of the Project prior to construction (would be incorporated into the specifications), while design adjustments may need to be made during construction to account for utility depths and locations.
Deliverables: Utility potholing plan and report in electronic (PDF) format.
Optional Task O.2: Infiltration Testing
Infiltration testing can be performed during Task 1.2 Geotechnical Investigation, to evaluate the infiltration feasibility, for a potential stormwater capture and infiltration Best Management Practice (BMP).
Deliverables: There are no direct deliverables. Percolation testing results will be incorporated into the plans and specifications as appropriate.
Optional Task O.3: Low Impact Development Plan
The Project may be subject to 2021 Municipal Separate Storm Sewer System (MS4) Permit Priority Development Project requirements. CWE can assist the City in preparing the Low Impact Development (LID) Plan, in accordance with the 2025 County of Los Angeles Public Works LID Standards Manual.
Deliverables: Draft and final LID Plans in electronic (PDF) format.
Optional Task O.4: Stormwater BMP Design
CWE will develop BMP design plans for the BMP shown to be located to capture runoff from DDI 23. The layout and phasing of the diversion from DDI 23 can be accommodated under this task.
Optional Task O.5: Low Impact Development Plan
The site construction may be over an acre and may require preparation of a Stormwater Pollution Prevention Plan (SWPPP). CWE can help develop a SWPPP for the project.

City of Santa Ana King Street Urban Greening Project Principal-in-Charge for design and implementation of a project that turned the debris-filled King Street parcel into a passive park-like area that supports multiple modes of transportation, such as walking and biking. Existing impermeable surface was removed to make way for drought-tolerant landscaping, shade trees, pervious pavement bicycle path, energy-conserving lighting, interpretive signage, seating, ADA improvements, stormwater bioretention and infiltration systems, waste receptacles, and public art.
The project will capture runoff from a local drainage area of about 10 acres. Stormwater flows into the project area and is directed into two bioretention basins that have specialized plant, soil, and gravel layers that are designed to filter pollutants and prevent trash from entering the City’s storm drain system. The stormwater then percolates through the bioretention basins into an underground stormwater infiltration chamber system. Once in the infiltration chamber system, 116,700 gallons per storm slowly percolate down into the North Orange County groundwater basin, where it will eventually become part of the local water supply. This groundwater basin provides drinking water for approximately 85% of North Orange County.

This project received the Yearbook of Engineering Achievement award from Civil + Structural magazine and Top Stormwater and Erosion Control Project award from Storm Water Solutions magazine in 2023; the 2024 ASCE Metropolitan Los Angeles Branch (MLAB) Outstanding Parks and Recreation Award, the 2024 ASCE Los Angeles Section Outstanding Parks and Recreation Project of the Year Award; and a 2024 CASQA Award as an Outstanding Stormwater Capture and Use Project.
CWE provided design services and produced site plans for the City of San Fernando and their San Fernando Regional Park project. The 9.5-acre park includes the San Fernando Regional Pool and Community Center, a children’s play area, and athletic fields. Six different alternatives were developed and evaluated to maximize benefits while reducing capital cost and ongoing life cycle cost. The infiltration system serves a drainage area greater than 950 acres and recharge groundwater sources with 446 acre-feet of runoff annually. CWE recommended upsizing the system and doubling the capture area (originally 400 acres) to maximize water quality benefits while remaining compliant with grant terms. The system has a single storm capture capacity greater than 24 acre-feet. The Project included establishment of landscapes around the subsurface storage system, restoration of the baseball field, restoration of the existing irrigation system, replacement and restoration of light poles and electrical conduit, design of 4,500 lineal feet of new storm drain to maximize capture, 6-inch sewer reconstruction, and restoration of one mile of roadway, sidewalk, and ADA curb ramps.
CWE recommended that 2,500 lineal feet of roadway be fully reconstructed as it was in a state of disrepair. The reconstruction involved removing the damaged pavement, installation of a new gravel base, and re-pavement.
Additionally, CWE evaluated the sidewalk and curb ramps along the section of road and identified eight curb ramps that required redesign due to ADAcompliance issues. The roadway, sidewalk, and ADA-curb ramp design and reconstruction came at no extra cost to the City. CWE secured funds from the SCWP and the LADWP to cover the full cost of this road reconstruction.
Additional tasks included: utility and community coordination; developing a preliminary design report emphasizing a gravity system as the best alternative to meet City needs; performing environmental studies that meet CEQA requirements; obtaining LACFCD permits; providing topographical surveys; conducting a geotechnical investigation; preparing a hydrologic and hydraulic study; providing potholing services; preparing an O&M manual for proposed structural stormwater BMPs, pretreatment devices, and stormwater infiltration system; providing bid support; and providing full service construction management, including but not limited to daily inspections, change order administration, cost estimates, scheduling, document control, and as-built development.

City of Santa Ana King Street Urban Greening Project
This project received the 2025 ASCE Orange County Branch Outstanding Environmental Engineering Project Award, the 2025 ASCE Los Angeles Section, Outstanding Environmental Engineering Project Award, the 2024 APWA Southern California Chapter BEST Project of the Year Award for Storm Water Quality >200,000 Population, the 2024 Storm Water Solutions magazine Top Project award, and a 2024 CASQA Award as an Outstanding Stormwater Capture and Use Project.
CWE provided design, implementation, and grant preparation for the King Street Urban Greening Project, turning the debris-filled King Street parcel into a passive park-like area that supports multiple modes of transportation, such as walking and biking. Existing impermeable surface was removed to make way for drought-tolerant landscaping, shade trees, pervious pavement bicycle path, energy-conserving lighting, interpretive signage, seating, ADA improvements, stormwater bioretention and infiltration systems, waste receptacles, and public art.
The King Street Urban Greening Project features an innovative approach in managing stormwater runoff. First, stormwater flows into the Project area and is directed into two bioretention basins, which have specialized plant, soil, and gravel layers that are designed to filter pollutants and prevent trash from entering the City’s storm drain system. The stormwater then percolates through the bioretention basins into an underground stormwater infiltration chamber system. This system is designed to infiltrate approximately 116,700 gallons of stormwater per storm. Once in the infiltration chamber system, the stormwater slowly percolates down into the North Orange County groundwater basin, where it will eventually become part of the local water supply. This groundwater basin provides drinking water for approximately 85% of North Orange County.
Tasks include researching existing field conditions and records, topographic survey, sizing the stormwater capture system in the conceptual design plans based on the 85th percentile storm event, environmental documentation, providing PS&ES, providing public outreach, utility coordination, geotechnical exploration, potholing, and preparing a Clean California Local Grant Program (CCLGP) grant application for this project that resulted in an award of nearly $1,500,000.
This project was completed on time and within budget.

CWE is creating an ADA compliant path from the parking space closest to the tennis court to the proposed pickleball courts, and the existing restroom. The two curbs at the parking drive aisle will be evaluated for compliance. The runoff tributary to the pickleball court area will be routed in a pipe to the existing catch basin on the south side via a new drainage pipe. Two (2) spectator seating with shade (prefabricated by USA Shades) will be included per the vendor’s design.
Ten-foot-high fencing will be placed along the courts. CWE is coordinating with LACPW, Regional Planning, and Fire for the required permitting, and the submittals will be made by LACDPR.
Tasks include a hydrologic analysis for the site and a drainage analysis for a pipe that requires relocation the proposed pickleball court to the existing catch basin; a topographic survey; a geotechnical evaluation; a design development package with preliminary accessibility, demolition, grading, utility, and construction; develop 75% construction documents package with civil, structural, and accessibility plans to detail accessibility, demolition, grading, utility, construction, erosion control plans, and LID BMPs details; reviewing and responding comments made Authority Having Jurisdiction (AHJ); and developing a complete set of stamped and signed construction documents.
This project is on track to being completed on time and within budget.

Creating a Better Tomorrow, Today® 27
In March 2026 – after two decades providing civil, water, environmental, stormwater, and survey services across
California – CWE began the next chapter for our team of dedicated staff by joining Apex Companies, LLC (Apex).
Established in 1988, Apex is a national multidisciplinary consulting and engineering services firm with a robust
portfolio of capabilities in water, environmental, health and safety, construction management, transportation, compliance and assurance, and infrastructure. Apex operates in all 50 states, supported by a highly capable and diverse team of over 2,000 technical, operations, and management professionals bringing expertise across a broad range of disciplines. These award-winning industry leaders actively work to cultivate the engineering protégés and environmental stewards of tomorrow.
In the realm of civil engineering projects for green and recreational spaces, CWE is synonymous with innovation, and stands out as the leader with a vast portfolio of multi-benefit stormwater capture and infiltration designs, surpassing all other firms in Southern California. In total, 14 CWE-led projects have been honored with 38 awards from the ASCE, CASQA, ENR, National Association of Flood and Stormwater Management Agencies (NAFSMA), APWA, USEPA, and Storm Water Solutions magazine. Our recognition for past design work illustrates our track record of pioneering civil design projects and demonstrates why CWE is the best choice to deliver innovative designs that will meet your goals while providing multiple benefits to you and your stakeholders. By choosing a firm capable of applying outside-thebox thinking and achieving real world results, you gain access to a seasoned team that can not only meet expectations for Rosewood Park’s expansion by providing the requested recreational enhancements, but exceed expectations of the City and Commerce community at large with consequential infiltration solutions that discreetly protect our precious water resources and puts money back in taxpayers’ pockets.
Rated No. 13 as an ENR All-Environmental firm and No. 68 in the top 200 overall, the firm is known for its technical expertise, rapid response, operational integrity, and exceptional client satisfaction. CWE and Apex’s standards are the same – we work tirelessly to bring the mastery, creativity, and commitment necessary to deliver forward-thinking results to enhance the communities we live, work, and play in, leaving them better for the next generation. The City of Commerce deserves nothing less than a trailblazing, solutions-oriented firm to provide PS&Es for Rosewood Park that will include pickleball court, pump track, walking/riding path, and landscaping feautures. CWE, an Apex Company is that firm!
Why CWE?
Delivering Award-Winning Results: We are widely recognized as an industry leader in the field of infiltration system design and installation, and some of the best place to implement BMPs and environmentally-friendly engineering solutions are within park facilities. We have a track record of successfully designing over 200 structural and non-structural BMP projects across Los Angeles County, including many subsurface infiltration projects underneath green spaces and parking lots that capture and treat stormwater runoff.

“Thanks to CWE’s creative approach and tireless dedication, the Los Amigos Park project not only helps the City accomplish their goals, but also serves as an excellent model for other cities to implement sustainable, forward-thinking projects. CWE consistently delivers innovative, tailored solutions that achieve our objectives and exceed our expectations. For civil design projects requiring skillful, nuanced engineering and a responsive and flexible team, I recommend CWE wholeheartedly.”

The majority of our personnel -- including our subconsultants -- have at least 10 years of experience in Los Angeles and the immediate surrounding area, and are uniquely familiar with local conditions, regulations, and permitting procedures specific to the governmental agency that serves the most populous County in the United States. Approximately 75% of our clients and 90% of our BMP project locations fall within Los Angeles County boundaries, so we come well-equipped to tackle Los Angeles County standards for DTSC, RWQCB, and SCAQMD coordination and specific ADA accessibility requirements.
The City of Commerce will strongly benefit from CWE’s streamlined services in navigating red tape that delays implementation of park expansions of this magnitude, as we comprehensively understand how to approach and overcome the unique challenges associated with this type of design work in Los Angeles County.
The Staff You See is the Staff You Get: As former managing civil engineers for LACPW, CWE’s Principals noticed a disturbing trend of key personnel being interviewed for contracts, but then never communicating with them again once the contract was awarded. CWE does not believe in this unacceptable “bait-and-switch” technique larger firms sometimes use to secure contracts, leaving their clients to deal with substandard personnel they have no familiarity with. The proposed personnel presented in this proposal, like Project Manager Nan Jia, PE, QSD/P, QISP, have extensive, unique, and coveted qualifications, and they will be the project team the City will communicate and work with for the duration of the project. This is one of many steps we take to demonstrate to our clients how much we value and respect them, and it makes a bold statement regarding our commitment to the City and the type of relationship we seek to have with our clients. Contacts listed on pages 23-25 can attest to CWE’s competency in communicating thoroughly, effectively, and directly with both clients and in coordination with subconsultants and each other on broad ranges of scopes.
