In this comprehensive interview with Mark Pestrella, Director of the Los Angeles County Public Works, Pestrella delves into the multifaceted responsibilities of overseeing the largest public works agency in the United States. Outlining the agency’s extensive scope, which includes managing water systems, roads, airports, and emergency responses for over 10 million residents across 4,000 square miles, he emphasizes the challenges of maintaining such vast infrastructure while simultaneously addressing climate change, which he describes as an ever-present threat that the agency has been planning for over the years.
Pestrella also discusses the agency’s strategic approach to leveraging historic federal funding from recent bills, such as the Bipartisan Infrastructure Law (BIL) and the Inflation Reduction Act (IRA), securing $1.5 billion to fund projects that prioritize climate resilience and equity. He underscores the ongoing challenge of workforce development in the face of a competitive labor market and highlights innovative approaches like AI and digital twins to enhance infrastructure maintenance and planning. As the 2028 Olympics approach, Pestrella shares his vision for showcasing LA County’s infrastructure, particularly along the LA River, as a reflection of the region's evolution and resilience.
