Document Description
The North County Transit District is proposing to retrofit the existing railroad bridge to improve structural stability to meet engineering requirements for channel deepening that is planned for the San Dieguito Lagoon Enhancement project. The retrofit will add new longitudinal bracing to every other span between bents 38 and 75 (north of lagoon channel); adding new transverse (sash) bracing below the existing sash bracing between bents 5 and 17 (within open water); treating and wrapping existing piles, sash bracing and cross bracing between bents 2 and 37 (within open water); and additional pile wrapping between bents 52 and 73 (north of lagoon channel and south of northern bridge abutment). No permanent impacts will occur to jurisdictional waters as a result of the proposed project.
