Stormwater System Gravity Discharge to Winery Canyon Channel

The contract awarded by Los Angeles County Parks & Recreation involves the construction of a gravity-fed discharge system designed to manage excess stormwater by directing it into the Winery Canyon Channel. This infrastructure project is focused on integrating new discharge structures with the existing natural waterway, ensuring efficient stormwater conveyance while minimizing environmental disruption. Key components include the installation of gravity-driven conduits, inlet and outlet structures, and comprehensive erosion control measures to stabilize soil and prevent sedimentation in the channel during high-flow events. The work must align with local hydrological conditions and maintain the ecological integrity of the surrounding landscape. The project is positioned in La Cañada Flintridge, California, with a ZIP code of 91011, and falls under NAICS code 237310, which classifies it as a civil engineering construction service related to water and wastewater infrastructure. As a subcontract, the work is likely part of a broader municipal stormwater management initiative managed by the county. The contract was posted on July 7, 2026, and its primary objective is to enhance the resilience of the local stormwater system by providing a sustainable, gravity-based solution for overflow management. The integration with Winery Canyon Channel requires precise engineering to ensure hydraulic efficiency, long-term durability, and compliance with environmental regulations.
