Marsh Trail Improvements for Watershed and Natural Resource Protection

The project involves targeted improvements to the Marsh Trail in Trione-Annadel State Park to safeguard watershed health and natural resources while enhancing access for visitors, park staff, and emergency responders. Key actions include removing an outdated cattle guard and pedestrian bridge over Schultz Creek, excavating within the existing road prism to install 18-inch culverts at locations where water is ponding, and stabilizing these culverts with gravel before capping them with Class 2 road base aggregate. A 20-foot pre-fabricated free span bridge will be installed to replace the previous structure, ensuring durable, low-impact crossing over the creek. All construction will be followed by full site restoration to return the areas to their pre-project condition, minimizing long-term disturbance to the surrounding environment. The initiative is led by the Regional Water Quality Control Board, Region 2 – San Francisco Bay, under the official title Marsh Trail Improvements for Watershed and Natural Resource Protection, and was posted as a forecast on July 25, 2025. The project is situated entirely within California, with primary oversight and coordination handled by Environmental Scientist Nicholas Siu-Ming Regent, who can be reached via email or phone for further inquiries. Although no solicitation number or NAICS code is specified, the effort aligns with broader objectives to mitigate erosion, improve water quality, and ensure sustainable trail access through ecologically sensitive areas.
