City of El Segundo Public Works Department

SECTION I – INTRODUCTION

The City of El Segundo is requesting written proposals from qualified environmental and geotechnical consulting firms to complete the investigation and post-closure land-use planning process for the former General Tile disposal site, located at 430 Sheldon Street, El Segundo, California 90245, SWIS No. 19-AA-5380, within Recreation Park.

The selected consultant shall review and supplement the City’s preliminary Phase I Office Investigation; prepare a detailed Phase II Field Investigation Work Plan; assist the City with obtaining LEA and CalRecycle concurrence on the proposed investigation approach, as applicable; perform the approved field investigation, environmental testing, surveying, and landfill-gas evaluation; prepare the draft and final investigation reports; prepare a Post-Closure Land Use Plan and, if required by the LEA, a Site Remediation and Maintenance Plan; and assist the City through the applicable agency review and approval process.

The City is requesting one complete proposal for the entire assignment. The consultant shall review all provided information before submitting its proposal and shall include the full cost of the investigation it recommends. The proposal shall not be structured as an initial review or planning phase followed by a separate proposal for field work.

SECTION II – SCOPE OF PROJECT

Background and History

The City has completed a preliminary Phase I Office Investigation and met with representatives of the LEA and CalRecycle on June 4, 2026. The agencies identified remaining data gaps concerning the lateral and vertical extent of the former disposal area, the thickness and condition of the landfill cover, the characteristics of the cover materials, and the potential presence of landfill gas.

The agencies directed the City to compare historical and current grades to assist in evaluating the former pit and disposal limits. They also identified metals, petroleum, and pesticides as expected environmental testing categories and stated that landfill gas should not be assumed absent without supporting field data.

Available historical mapping indicates that a quarry or pit was present at the site before it was filled and leveled. Existing shallow borings and the previous cone penetration test did not conclusively establish the top and bottom of waste throughout the suspected disposal area.

The City is currently procuring a consultant to complete the remaining investigation and regulatory process. The selected consultant shall review and supplement the preliminary Phase I Office Investigation, prepare a detailed Phase II Field Investigation Work Plan for City and applicable agency review or confirmation, perform the Phase II Field Investigation following City authorization, prepare the final investigation report, and use the accepted investigation results as the technical basis for preparation and regulatory review of the PCLUP/SRMP.

City of El Segundo Public Works Department

SECTION III – SCOPE OF SERVICES

The Selected firm shall

1. Determine the horizontal extent of waste or disposal-related fill.

2. Determine the vertical extent and thickness of waste.

3. Identify the depth and elevation of the top and bottom of waste.

4. Determine the thickness, composition, variability, and condition of the landfill cover.

5. Identify native soil or the former quarry surface beneath the disposal materials.

6. Characterize environmental conditions within the cover, fill, waste, and underlying soils.

7. Evaluate the presence and potential migration of landfill gas.

8. Prepare a technically defensible report suitable for LEA and CalRecycle review.

9. Respond to agency comments and revise the report as needed to complete the review.

10. Review, verify, and supplement the City’s preliminary Phase I Office Investigation as necessary to support the Phase II Field investigation and PCLUP/SRMP.

11. Prepare a detailed Phase II Field Investigation Work Plan for City and agency review before intrusive fieldwork begins.

12. Identify corrective measures, monitoring requirements, construction limitations, and additional information necessary to support the proposed post-closure use.

13. Prepare a PCLUP and, if required by the LEA, an SRMP that addresses the proposed

Recreation Park improvements and demonstrates compliance with 27 CCR Section 21190.

14. Assist the City in responding to agency comments and obtaining LEA and CalRecycle approval of the investigation report and PCLUP/SRMP.

SECTION VI – SELECTION PROCESS

A. Initial Screening All RFP responses will undergo an initial review to determine responsiveness to the instructions herein. Those RFP responses initially determined to be responsive by meeting the RFP requirement as indicated herein will proceed to the next phase of the evaluation process.

B. Evaluation Activities

RFP responses deemed as having met the standard RFP requirements as indicated herein are then evaluated by an Evaluation Committee which comprised of City staff. The RFP submittals are scored and assigned a ranking of one (1) through ten (10), ten being the highest possible score. The following criteria have been assigned percentages that the criteria will be scored against, based upon but not limited to the following evaluation criteria factors:

Criteria

City of El Segundo Public Works Department

Criteria Description Assigned Percentage

Consultants Expertise (Firm and Individual Qualifications) 40 Quality of proposed services 20 Extent to which the consultant services meet the City’s needs 20 Cost 20

The Evaluation Committee will review and rank the proposals based upon the ‘Ranking Criteria’ table, and then re-rank the proposals in consideration of the Cost Proposal and overall value of the proposed services.

The top-rated consultants may be requested to come to an interview with the Evaluation Committee, who will determine the final rankings. The ultimate scope of work, schedule, and fee will be negotiated with the top-ranked firm, resulting in a recommended contract award by staff to the City Council. The successful bidder is selected by the City Council acting within its sole discretion. The City Council is under no obligation to contract with any bidder. If an agreement cannot be reached with the top-ranked firm in a reasonable amount of time, negotiations may begin with the next highest-ranking firm until an agreement is reached.
