Implementation Update July 2024

The Safe, Clean Water Program funds stormwater initiatives that improve water quality, increase our local water supply, and provide community benefits, like green spaces and parks. The program cultivates regional and community partnerships and prioritizes historically underserved communities.

This newsletter provides important updates on the Regional, Municipal, and District Programs, designed to help our community stay informed and engaged. For further information on regional proposals, including those that are funded and under consideration, please visit our projects webpage.

We look forward to our ongoing collaboration as we remain dedicated to implementing and refining the Safe, Clean Water Program. Your input and feedback are crucial to us, and we appreciate your valuable opinions. Feel free to share any comments or questions you may have. Please do not hesitate to contact us.

Key Dates to Know

Project Highlight

Adventure Park Multi-Benefit Stormwater Capture Project is under construction. The multi-benefit project at Adventure Park in unincorporated area of Whittier aims to improve water quality and supply while enhancing the park area. The project will collect and treat runoff from Sorenson Drain, storing it underground and sending some to the sewer system for further treatment and reuse. Additionally, the project will include recreational improvements such as new athletic fields and natural enhancements like planting more trees and installing bioswales with native species for water quality treatment.

Adaptive Management

Watershed Planning

In alignment with Supervisor Horvath’s motion to Accelerate the SCW Program, the SCW Program has initiated Watershed Planning efforts to facilitate regional and watershed-based planning that identifies project opportunity areas and refines Population Indicators (i.e., targets) that will support strategic investment.

A series of workshops will be scheduled with various interested parties and the governance committees to inform and gather input/feedback about the effort to establish Initial Watershed Plans, starting with one of our primary collaborators, the Watershed Area Steering Committees (WASCs).  In their upcoming meetings, the WASCs will learn more about the watershed planning effort and lend their expertise to help identify watershed area capabilities, priorities, and strategies through facilitated workshops.

A new SCW Program Watershed Planning Section has been created to lead this important effort. You may contact them at

Metrics and Monitoring Study

The Metrics and Monitoring Study (MMS) is finished and will help improve the Safe, Clean Water (SCW) Program. Some of its recommendations are already being put into action, and others are being considered through watershed planning. The study aimed to develop new ways to measure and monitor our stormwater efforts, with the goal of making better decisions and maximizing benefits for everyone involved. Please join us for an MMS Info Session that is scheduled for July 25, 2024, at 9:00 am to hear more about the study and next steps.

Renewal of Municipal Transfer Agreements

The SCW Program is currently working on updates to the Reporting Module to streamline the renewal process for the Municipal Transfer Agreements (TAs).  These updates are anticipated to be completed before the current TAs expire. Please note that SCW Program Payments will generally be available for disbursement by December 31 based on timing of revenues actually collected by the SCW Program.  Therefore, any minor delays in renewal of the Transfer Agreement are not expected to affect eligibility or the schedule for the disbursement of funds.


Public Education and Community Engagement Grants Program

Safe, Clean Water is partnering with the Water Foundation to develop and administer a Public Education and Community Engagement Grants Program.  The program will support education and community engagement efforts related to stormwater and urban runoff capture within the LA County Flood Control District.  The Grants Program is in the early development stages and is expected to formally launch in September 2024.  We encourage all eligible parties to apply for funding. Additionally, we encourage all interested parties to participate in the program design process by attending one of two public input sessions. Public Input Sessions are scheduled for Thursday, July 11, 2024 at 9am and Wednesday, July 24, 2024 at 4:30pm. Note that Zoom registration is requested.
