Temporary Closure to the Public

The District is replacing the concrete ramp, stairs, landing and walkway at our headquarters. We apologize for the delay in opening, but the improvements will improve access to our lobby for customers and visitors. The closure is estimated to extend through November 2021. A temporary payment drop box is located near the flagpole in the parking lot at 766 Main Street in Half Moon Bay.
