BACKGROUND:
Water Division Updates
Cypress Water Production Facility (CWPF) and Distribution System Update Well No. 5 remains offline due to the detection of benzene and the construction project to upgrade the CWPF. The State’s Division of Drinking Water (DDW) and the Los Angeles Regional Water Quality Control Board (RWQCB) have been investigating possible sources of benzene, and information is available at https://www.lomitawater.com/news/.
In March, RWQCB issued an order to Chevron Pipeline Company to provide information on the pipelines that are located in Lomita approximately 25 feet from the CWPF. The Order requests information be provide by the end of June on the pipeline materials, products transported, integrity tests, spill records, and previously conducted sample results.
In March 2023, the City pumped 0.0 acre-feet of groundwater from Well No. 5. All drinking water was supplied with imported water from West Basin MWD. In March 2023, the City imported 134.1 acre-feet from West Basin MWD. Monthly water reports can be found at www.lomitawater.com/oversight/water-quality-reports/.
The City resumed its water tours at the Cypress Water Production Facility in Summer of 2022 after a two-year hiatus. A tour was hosted on a Saturday in March for eight community members. Residents who are interested in touring the facility may sign up for a monthly tour at https://www.lomitawater.com/water-tours/.

Percent Project completion 98%
Overall Project, invoiced/approved $4,126,685
Overall Project budget (approved contracts) $4,835,131
The City shares project updates on https://www.lomitawater.com/ as new information is available. In addition, a short video describing the GAC project and treatment process is available here: https://www.lomitawater.com/infrastructure/granular-activated-carbon/.
Street Reconstruction – Zone G
This project consists of overlaying and reconstructing certain streets in Zones G (just north and south of Lomita Boulevard and east of Eshelman Avenue), as detailed in the Pavement Management Program (PMP). This project includes significant repairs and resurfacing of streets where slurry seal would not be sufficient to extend the life of the street.
Design of the project was awarded to David Evans and Associates in July 2022 and is scheduled to be completed in the first half of 2023. Extensive field investigation and sampling have taken place to evaluate the road condition on the 17 streets included in this project. The City has received these technical reports. Construction of the project is programmed for Spring 2024.
Progress As of March 31, 2023
Percent Project completion 20% (of design)
Overall Project, invoiced/approved $36,481
Overall Project budget $1,200,000
247th Street Area Watermain Project
This project consists of abandoning a watermain that runs north and south within private properties crossing 246th Street, 247th Street, 247th Place, and 248th Street. The proposed new water main will extend from 246th Street beyond the City boundaries, looping within the City of Los Angeles right of way and along Western Avenue (which is Caltrans right of way), and connecting back to the City of Lomita along 247th Street, 247th Place, 248th Street and Lomita Blvd. This project consists of constructing approximately 3,300 linear feet of PVC water pipeline and appurtenances (fire hydrants, valves, services, and fittings). The existing pipeline located in private property will be abandoned.
Design of the project was awarded to Onward Engineering in November 2021. The permit from Caltrans was approved in September 2022. The encroachment permit and traffic 4 control plans were approved by the City of Los Angeles in December 2022. Onward Engineering is working to schedule their subconsultant to complete potholing. The final design of the project has been submitted to the City for final review.
Progress As of March 31, 2023
Percent Project completion 85% (of design)
Overall Project, invoiced/approved $102,248
Overall Project budget $1,499,916
Emergency Generator
This project consists of the selection and design of an emergency generator that will be capable of servicing the Appian Way Pump Station as needed. The design of this project was awarded to AEPC Group in July 2022 and is scheduled to be completed in March 2023. Construction of the project is scheduled for Summer 2023.
For the month of March 2023, City staff reviewed and provided comments for the 90% design package for the project. Due to the long lead time for generators (~60 weeks), AEPC Group the consultant is looking into alternative generators to rent to ensure the City has a backup power source for the Metropolitan Water District shutdown scheduled to begin in November 2023.The City is planning to procure the generator in April, as well as receive the final PS&E for the project.
Progress As of March 31, 2023
Percent Project completion 50%
Overall Project, invoiced/approved $52,030
Overall Project budget $76,365
Narbonne Avenue Water Replacement and Street Rehabilitation Project This project consists of constructing approximately 1,600 linear feet of PVC water pipeline on Narbonne Avenue from PCH to the southern end of the City of Lomita. Per the proposed 2015 Water Master Plan, the proposed watermain will be a new 8-inch PVC water main to provide improved flow, pressure, and fire protection. This new water main will replace the existing 1928 6-inch and 8-inch water mains.
Design of the project was awarded to David Evans and Associates in December 2022 and is scheduled to be completed in the third quarter of 2023.
Progress As of March 31, 2023
Percent Project completion 3%
Overall Project, invoiced/approved $0
Overall Project budget $199,940
New Groundwater Well Feasibility Study
The purpose of this study is to identify preliminary locations where construction of a new groundwater well is feasible. The installation of a new well would minimize the City’s long- 5 term reliance on imported water and provide a contingency well in case of future adverse impacts to Lomita Well No. 5. The City currently has groundwater rights of 1,352-acre feet (ac-ft) in the West Coast Basin, and in its last year of normal operations, CY 2018, Well No. 5 only produced 561 ac-ft of groundwater.
This study was awarded to Stetson Engineering, Inc. in February 2023 and the kick-off meeting was held in early March. Stetson Engineering is currently acquiring and reviewing data. The study is scheduled to be completed in July 2023.
Progress As of March 31, 2023
Percent Project completion 5%
Overall Project, invoiced/approved $0
Overall Project budget $63,135
Appian Way Pump Station Roof Project
This project will consist of designing and constructing a new roof for the Appian Way Pump Station, which will require a material resistant to termite infestation. The existing roof has termite damage and due to the building being utilized for drinking water, the building cannot be fumigated.
The City requested proposals in February 2023 and anticipates presenting an award for a contract to the City Council in April.
Stephenson Center Maintenance Project
This project consists of design and construction for upgrades to the restroom facilities as well as restoration/replacement of the three-level roof at The Stephenson Center in Lomita Park. The requirements for design include upgrades to all fixtures in the men’s and women’s restrooms to comply with ADA access needs, new toilet stall partitions, new doors, re-roofing the building, and replacement of the skylights.
The Request for Proposals (RFP) for design of this project was issued on March 30, 2023 and proposals are expected in May.
Encroachment Permit Review/Approval
In March 2023, staff received and reviewed 17 encroachment permit applications from various utility companies, contractors, and residents. Seven encroachment permits were issued. Public Works now has an on-line portal for encroachment permitting, available at https://lomitaca.viewpointcloud.com/categories/1081.
Public Safety and Traffic
Public Safety and Traffic Commission (PS&TC) did not meet March. Staff received proposals for developing a Traffic Calming Toolkit and will be coordinating public workshops in the future with the PS&TC. The Toolkit will provide tools for the City to utilize in addressing traffic concerns across the City.
6 All new requests for traffic issue investigations are accepted through the on-line OpenGov portal and may be submitted here: https://lomitaca.viewpointcloud.com/categories/1081.
Public Works Field Operations Division (Parks/Street/Trees) Updates In March, Public Works Field Operations crew assisted in water main repairs. The Parks Division replaced a tree at Hathaway Park and one tree at Teuchert Park. The Parks Division also worked on replacing dying and outdated plants at Narbonne Plaza and the City Parking Lot at 245th Street.
