Marsh Creek State Historic Park Emergency Septic System Excavation and Repair

The California Department of Parks and Recreation is undertaking an emergency repair at Marsh Creek State Historic Park to replace a failed septic system serving the residence on-site. The project involves excavating the existing septic tank and inlet pipe, removing them, and installing a new 1,250-gallon septic tank with a 30-foot black ABS plastic inlet pipe, ensuring proper elevation and slope for effective inflow and outflow. The gray water system will be repaired and integrated into the new outflow configuration to restore full functionality. All excavated material will be backfilled with sand and covered with clean, non-native soil already available on-site to minimize environmental disruption. New polyethylene risers with secure covers will be installed to provide safe, long-term access for future maintenance inspections and pumping. The work will be conducted by State Park staff using a combination of heavy equipment and hand tools to complete the repair efficiently while preserving the historic integrity of the area. The project is forecasted with a posted date of May 26, 2026, and is managed by the Department of Parks and Recreation under the oversight of Diana Fong, District Environmental Coordinator, who serves as the primary point of contact. No formal solicitation number or set-aside designation has been assigned, and all work is being executed internally without external contracting, reflecting the urgency and nature of the emergency repair.
