Flood control efforts in San Francisquito Creek are challenged by a sediment mound caused by storms in recent years, which has raised the creek's elevation by seven inches. Although it doesn't pose an immediate flood risk, it complicates upstream flood control efforts. Removal would cost $1.6–2 million and could take years. Caltrans may handle the removal, but it's not a priority. Monitoring will continue, with efforts by Grassroots Ecology to manage vegetation buildup. Councilman Greer Stone criticized the costs, suggesting a more hands-on approach could be cheaper.
"Recent higher flows in the creek have not moved this mound at all, and now there's vegetation growing on it. So we think it's pretty stuck there," Project Manager Deanean Ni said.
"Removing the sediment would cost $1.6 million to $2 million because the area is never dry and hard to access," Executive Director Margaret Bruce stated.
