Roosevelt Beach Culvert Work Begins April 1

The California Department of Parks and Recreation is set to begin construction on a key infrastructure upgrade at Roosevelt Beach starting April 1, 2026. The work will focus on replacing aging drainage systems at the western end of the Pullman watercourse and is expected to continue on weekdays for approximately three months.

The project will take place within Half Moon Bay State Beach, a popular coastal destination, where officials say improvements are necessary to maintain safe public access and protect surrounding infrastructure.

Project Aims to Improve Drainage and Prevent Erosion

The construction effort will replace two failed culverts with a single, larger system designed to handle stormwater more effectively. The upgrades are intended to improve drainage capacity, reduce erosion risks and safeguard nearby assets, including the beach access area and the coastal trail.

Upgraded Culvert System to Strengthen Coastal Infrastructure

Officials noted that the culverts play a critical role in allowing water from the Pullman drainage system to pass beneath both the Coastal Trail and a driveway leading to a beach parking area. Their failure has created long-standing safety and access issues.

The new, larger culvert is expected to provide a more resilient solution capable of withstanding heavy storm events and long-term coastal wear.

History of Failures Prompted Urgent Action

The need for replacement stems from years of deterioration caused primarily by undercutting at the culvert outfall.

Past Storm Damage Led to Closure of Beach Access Road

During the winter of 2018, the driveway leading to the Roosevelt Beach parking lot began collapsing due to erosion. By 2020, significant portions of the roadway had fallen into the watercourse, forcing officials to close access to the parking area entirely.

The culverts, located roughly 300 feet northeast of the beach outlet, had deteriorated to the point where continued use posed risks to both infrastructure and public safety.

• Coastal Resilience: Projects like this are increasingly critical as coastal areas face stronger storms and rising sea levels.
• Public Access: Restoring drainage systems helps reopen and maintain access to beaches and recreational trails.
• Infrastructure Lifecycle: Culverts and drainage systems often fail due to erosion and require periodic upgrades, especially in coastal environments.
• Environmental Impact: Improved water flow management can reduce sediment disruption and protect nearby ecosystems.
