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 April 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 April 2023, the City imported 143.6 acre-feet from West Basin MWD. Monthly water reports can be found at www.lomitawater.com/oversight/water-quality-reports/.
The City hosted a water tour at the CWPF on April 20th for four community members.
Residents who are interested in touring the facility may sign up for a monthly 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 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.

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. Onward Engineering has performed potholing. At one location soil contamination was observed.
Onward Engineering’s team will perform another round of potholing to investigate alternate alignments and/or validate the contamination. If the pipe alignment will be diverted, revised final design of the project will be resubmitted to the City for review.
Progress As of April 30, 2023
Percent Project completion 85% (of design)
Overall Project, invoiced/approved $102,248

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 May 2023.
Construction of the project is scheduled for Summer 2023.
For the month of April 2023, City staff reviewed the 100% final design package for the project. Due to the long lead time for generators (~60 weeks), 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. Staff anticipates requesting Council authorization for early procurement of generator. The final revised PS&E for the project are scheduled to be submitted in May.

4 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 submit a 60% preliminary design package to the City in early May.
The final PS&E 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 produced 561 ac-ft of groundwater.
This study was awarded to Stetson Engineering, Inc. in February 2023. Stetson Engineering is currently acquiring and reviewing data and a preliminary report is expected to be submitted in May. The study and final report is scheduled to be completed in July 2023.

Appian Way Pump Station Roof Project
This project will consist of designing and constructing a new roof for the Appian Way Pump Station. The design contract has been awarded to Tetra Tech, Inc. and design will begin soon.
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. 5 The Request for Proposals (RFP) for design of this project was issued on March 30, 2023 one proposals is received from BOA Architecture.
