Twitchell Dam Sediment Removal
RPS is serving as Project Manager for the Santa Maria Water Conservation District to manage the District’s Sediment Removal Project at Twitchell Dam. Due to historic fires and resulting flooding, the dam is impacted by substantial sediment buildup in the spillway and downstream channel which will impact future releases and could pose potential threats to Santa Maria and Guadalupe. RPS developed and implemented the District’s Emergency Declaration coordinating various federal, state, and local agencies involvement including Section 7 consultations with the US Army Corps of Engineers so that removal operations can begin.
RPS recently completed the District's annual Maintenance Plan and is currently processing the necessary federal and state permits to authorize the plan.
