SANDAG Selects HDR for LOSSAN Rail Realignment Project

TheSan Diego Association of GovernmentsselectedHDRto lead the next phase of work on its critical San Diego LOSSAN Rail Realignment Project.HDRwill lead the environmental clearance and advanced conceptual engineering.HDRhas worked withSANDAGsince 2020 on the San Diego Regional Rail Alternatives Analysis and Conceptual Engineering Study. This set the groundwork for the realignment.

HDR, partnering withMott MacDonaldamongst others, will work withSANDAGto complete the CEQA and NEPA processes in 2026. This will support the goal of opening the relocated rail line by 2035.

“Not only is it a vital project that will keep our community connected to a national resource, but it’s also a crucial step towards addressing climate change,”HDRPrincipal-in-Charge Rob Klovsky said. “With the trust and leadership ofSANDAG, I am confident that we can bring this project to fruition and keep our community connected.”

Within the city of Del Mar, the existing single track sits atop coastal bluffs that are rapidly eroding. This project will relocate about 5 miles of the rail line inland, to a double-tracked alignment located primarily in tunnel. This will be through Los Peñasquitos Lagoon in the City of San Diego. Enhancing safety and reliability, this project will increase capacity along the Los Angeles-San Diego-San Luis Obispo (LOSSAN) Rail Corridor.

“This project is all about protecting a critical rail corridor and an economic lifeline for our region,” saidHDR项目经理洛伦佐·加里多。“我是兴奋be part of delivering the long-term solution of relocating the tracks from the coastal bluffs that will be a lasting benefit for future generations.”

The project will be the first on the LOSSAN Corridor designed to accommodate train speeds up to 110 mph. Therefore, it could pave the way for future speed improvement projects on the corridor.
