The “San Geronimo Floodplain and Riparian Restoration” project has occurred upstream of the Roy’s Pools Fish Passage and Floodplain Restoration site and focuses on addressing limiting factors for coho survival, improving water quality and riparian function, and improving conditions for floodplain and off-channel habitat development.
In total, this project will restore 0.25 miles and 5 acres of the floodplain corridor along the former San Geronimo golf course property in San Geronimo, California. A primary feature of this project is creating off-channel habitat, these include creation of secondary channels and floodplains that offer coho salmon rearing and food resources during high storms and spring rearing. Floodplains also offer chances for sediment sorting and storage, pool scour, helping improve spawning habitat and instream gravel quality. This project also creates valuable floodplain corridors for terrestrial wildlife movement, greatly increasing the width of the riparian corridor, which will ultimately increase amount of trees for nesting birds and foraging animals.
This project was funded by the California Department of Fish and Wildlife, NOAA Restoration Center, and Turtle Island Restoration Network. Project engineering and design was done by Environmental Science Associates, and project construction was done by Hanford ARC and SPAWN. The Landowner, The Trust for Public Land, has been a great willing partner.
