The Marin Municipal Water District is seeking $4 million in grants to fund two of its dam projects. The district board unanimously approved two grant applications for the state Department of Water Resources’ safety and climate resiliency program. The grants would give up to $2 million for each project. The funds would go toward repairing spillways at various dams and replacing valves and actuators at Phoenix and Lagunitas dams. Actuators help control water flow. “This opportunity for the submission of these proposals seems like it’s quite new, or this is a new program focused on the maintenance of dams that predate a certain period,” Ranjiv Khush, the board president, said at its meeting on Oct. 15. “It’s a great opportunity that’s come up from our department resources and I was really excited to see that we jumped on it.”
