HomeMy WebLinkAboutGM Monthly Report - May 2026 May 20, 2026 TO: Chair and Members of the Board of Directors FROM: Robert C. Thompson General Manager SUBJECT: May Status Report The following status report is submitted for your review and consideration. 1. Public and Environmental Health New Traffic Signal on Ellis Avenue OC San is working closely with the City of Fountain Valley to coordinate schedules for the powering and programming of a new traffic signal at the intersection of Ellis Avenue and Mt. Langley Street. Once operational, the signal will provide a protected left turn onto Ellis Avenue from Mt. Langley Street for staff and guests leaving Headquarters as well as for the future laboratory building. The traffic signal project also adds pedestrian crosswalks. Ownership of the traffic signal will be transferred to the City of Fountain Valley. 2. Sound Finances and Increasing Efficiency Budget Preparation Continues Budget preparation for Fiscal Years 2026-27 and 2027-28 is nearing completion. Revenue, debt service, capital outlay, and operating expenses have been submitted, reviewed and included in the proposed budgets. Staff presented on the Capital Improvement Plan at the May Committee meetings, along with the Insurance Program at the May Administration Committee meeting. A wrap-up on the proposed budgets will be presented at the June Committee meetings, with the full Board voting on the budgets at the June meeting. 3. Recovering Valuable Resources Orange County Waste and Recycling Update – Food Waste Project OC San hosted a meeting with OC Waste and Recycling (OCWR) and regional digester owners on April 30 to discuss OCWR’s long-range food waste management strategy and collaboration opportunities for co-digestion. It was determined that OC Chair and Members of the Board of Directors May 20, 2026 Page 2 of 4 San and OCWR will be the primary partners for the initial phase of feasibility study, and the remaining regional wastewater digester owners may join in a later phase. 4. Community Outreach and Transparency Engaging with our Public This month, OC San hosted 16 tour groups, including students from Cal State Fullerton, University of California, University of California, Riverside, Servite High School, Santiago Canyon College, and groups from the City of Irvine, City of Newport Beach, Water Utility CEO, San Diego Water, Victor Valley Wastewater, OC Department of Education, a public tour, reaching over 200 people. In addition to leading a tour for the Water Utility CEO group, I also provided a presentation on Supercritical Water Oxidation and Deep Well Injection. 5. Legislative and Industry Affairs Legislative Update • Federal Congress continued work on Fiscal Year 2027 appropriations through committee budget hearings, including funding discussions for the U.S. Environmental Protection Agency (USEPA). During the hearings, lawmakers from both parties expressed opposition to the Administration’s proposed cuts to the State Revolving Fund. Separately, USEPA released its Water Reuse Action Plan 2.0, outlining efforts to support industrial water reuse, and announced plans to develop new guidance for PFAS in land-applied biosolids based on real-world application scenarios. • State As the legislative session progresses, fiscal committees are reviewing bills alongside the State’s budget outlook. Bills with significant costs must show both policy value and fiscal feasibility to advance. The Governor released the May Revision of the State Budget the week of May 11, providing updated revenue projections and spending proposals. The May Revise will play a key role in budget negotiations and could impact the viability of pending fiscal legislation as the Legislature approaches major deadlines and floor action later this month. Chair and Members of the Board of Directors May 20, 2026 Page 3 of 4 • Local City officials across Orange County are exploring ways to address funding gaps as discussions begin for the 2026–27 budget cycle. Fullerton, Orange, and San Clemente will each have at least one dedicated sales tax measure on the November ballot. Meanwhile, cities including Irvine and Huntington Beach are considering hiring freezes and other strategies to address projected deficits. Brea and Placentia are also updating local ordinances to strengthen regulations on short-term rentals. The new measures include permit requirements, caps on visitors, and increased fines for violations to help reduce parties, parking issues, and noise complaints. OC San Receives Recognition • California Association of Public Information Officers (CAPIO) OC San won the 2026 Excellence in Public Information and Communications (EPIC) Award in the category of Internal Communications for our Take Your Kid to Work Day event held in 2025. The EPIC Awards recognize outstanding public agency communications programs that rise above through innovation, creativity, and meaningful community impact. OC San was honored for creating an engaging and memorable experience that highlighted the important work of public service while connecting employees’ families to the agency’s mission. 6. Workforce and Administration Emergency Response Training On May 4–7, 2026, OC San conducted a series of comprehensive tabletop exercises, facilitated by a third-party consultant, to evaluate organizational preparedness and emergency response capabilities. The exercises included simulations of high influent wastewater emergencies, Santa Ana River Interceptor (SARI) trunkline rupture scenarios, and various power outage events designed to assess the effectiveness of emergency response protocols, operational continuity, cross-functional coordination, and Emergency Operations Center decision-making and communications capabilities. Key observations, lessons learned, and opportunities for improvement are currently being assessed, with corrective action plans under development to further enhance organizational preparedness and resilience. Leadership Academy for Executives and Managers On April 29, a total of 23 OC San executives and managers completed the Leadership Academy training program consisting of seven customized sessions over a four-month period. Delivered in partnership with The Centre for Organization Effectiveness, the program was tailored to OC San’s leadership priorities and focused on governance, self-awareness, team leadership, coaching and development, conflict resolution, and strategic influence. To complement the training sessions, participants completed Chair and Members of the Board of Directors May 20, 2026 Page 4 of 4 leadership assessments and received individualized coaching to strengthen their self-awareness and identify development opportunities. Executives received additional coaching informed by 360-degree feedback. With the program now complete, participants are better equipped with practical tools to enhance communication, collaboration, address workplace challenges and support OC San’s organizational goals. This leadership program is a testament to OC San’s ongoing commitment to employee development, succession management, and organizational excellence.
