Tiscornia Marsh Habitat Restoration and Sea Level Rise Adaptation Project

The Tiscornia Marsh Habitat Restoration and Sea Level Rise Adaptation Project is a forecast initiative located in San Rafael, California, specifically along the northern boundary of the Canal neighborhood. Managed by the City of San Rafael and the California Department of Fish and Wildlife, the project encompasses a 30-acre area including Tiscornia Marsh and portions of Pickleweed Park. The primary scope of work involves reconstructing 1.5 acres of eroded tidal marsh and gravel beach, preserving eight acres of existing marsh, and restoring four acres of diked marsh by reconnecting it to tidal inundation. Additionally, the project includes the construction of a new 600-foot levee on the south side of the diked marsh and the improvement of 1,100 feet of existing shoreline levee to enhance flood protection, public access, and habitat benefits. Classified under NAICS code 237990, the project is designated as a Qualifying Restoration Project under section 1671(d)(1) of the Fish and Game Code and complies with California Code of Regulations section 15096, subdivision (i). The California Department of Fish and Wildlife has issued Restoration Management Permit No. RMP-2026-0031-R3, determining that the project will result in substantial cumulative benefits to native fish, wildlife, plants, and their habitats. Environmental reviews indicate that the project will not have a significant environmental effect within the jurisdiction of the Department of Fish and Wildlife, and the lead agency has prepared an Environmental Impact Report along with a monitoring plan and additional mitigation measures.
