SUBJECT: Monthly Report for the Public Works Department RECOMMENDATION:
Receive and file the monthly report for the Public Works Department.
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 July 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. The City has not yet received the invoice for the volume of imported water utilized in July 2023 from West Basin MWD and it will be included in the August 2023 monthly report. The Monthly water reports can be found at www.lomitawater.com/oversight/water-quality-reports/.
The City has been offering monthly tours of the Cypress Water Production Facility. A tour was hosted on July 11th for 10 community members. Residents who are interested in touring the facility may sign up for a tour at https://www.lomitawater.com/water-tours/.

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.
The design of the project was awarded to David Evans and Associates (DEA) in July 2022, and the design is scheduled to be completed in 2023. Construction is programmed for Spring-Summer 2024. Extensive field investigation and sampling have taken place to evaluate the road condition on the 17 streets included in this project, and the City has received related technical reports. In addition, DEA has identified and provided 3 preliminary cost estimates for curb ramps that require upgrades in the project zone. DEA is preparing the 60% detailed design drawings, which are expected in August 2023.
Progress As of July 31, 2023
Percent Project completion 35% (of design)
Overall Project, invoiced/approved $86,254.81

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 control plans were approved by the City of Los Angeles in December 2022. The permit fees for Lomita to work in the City of Los Angeles’ Right-of-Way is approximately $318,247.20.
Onward Engineering has completed two rounds of potholing. The first round identified an unknown pipe requiring a new alignment and additional potholing. The second round of potholing has shown elevated levels of Lead in the area. Onward Engineering is working on an alternate alignment and is planning for further potholes to avoid contaminated soil.
Following this, the final design will be resubmitted to the City for review.
Progress As of July 31, 2023
Percent Project completion 95% (of design)
Overall Project, invoiced/approved $119,821.50
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 was completed in June 2023. City Council approved the design in June 2023, and authorized release for bidding.
Procurement of a short-term rental and final generators have been initiated, and the project has been posted to bid boards for contractors to submit bids. A Pre-Bid meeting will be held on August 8th and the bid due date is August 17. 4 Progress As of July 31, 2023

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. 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 main.
Design of the project was awarded to David Evans and Associates (DEA) in December 2022. DEA has performed a pavement analysis of the current conditions, and the 60% preliminary design package was sent in July. The pavement analysis report is expected to be sent in early August. DEA also plans to pothole at various locations to determine depth of possible conflicting utilities. The final design is scheduled to be completed in the third quarter of 2023.

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 longterm 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 pumped 561 ac-ft of groundwater.
In February 2023, this study was awarded to Stetson Engineering, Inc, who is currently acquiring and reviewing data. In June, the preliminary report was received, and staff have begun the review. The study and final report are scheduled to be completed in August 2023.
Progress As of July 31, 2023
Percent Project completion 75%
Overall Project, invoiced/approved $29,682.75
Overall Project budget $63,135
Appian Way Pump Station Roof Project
This project consists of designing and constructing a new roof for the Appian Way Pump Station. The design contract has been awarded to Tetra Tech, Inc. and they have submitted 60% design drawings. Lomita staff is reviewing the drawings. 5 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 Project design has been awarded to BOA Architecture; they have visited the site and provided preliminary drawings for the restroom layout to meet accessibility design requirements. Lomita staff are reviewing the drawings.
Engineering/Regulatory Updates
Encroachment Permit Review/Approval
For the month of July 2023, staff received and reviewed 11 encroachment permit applications from various utility companies, contractors, and residents. Permits were issued to 6 applicants. Public Works now has an on-line portal for encroachment permitting, available at https://lomitaca.viewpointcloud.com/categories/1081.
Stormwater
In July, a seat became available to represent the Dominguez Channel Watershed Group in the Watershed Area Steering Committee (WASC) for South Santa Monica Bay, Safe Clean Water Program. The WASC is composed of 18 members representing various stakeholder groups, and the purpose is to consider and score projects applying for regional funding. The Public Works Director from Lomita was selected for this role with Lawndale as the alternate. The meetings occur monthly.
Sewer System
In July, the County of Los Angeles Department of Public Works provided Lomita the quarterly Sanitary Sewer Overflow for April to June documenting no reportable sewer overflows and confirming entry into the California Integrated Water Quality System.
Public Safety and Traffic
Public Safety and Traffic Commission (PS&TC) met in July in conjunction with the Traffic Calming Workshop to receive input on areas of concern for community members.
