PACE provided civil and structural engineering design and construction support services to completely remove and replace the interior and exterior coatings from an elevated 2.0-MG steel water tank. The project also included replacing access hatches, grating, and ladders; adding rails; and improving venting systems and overflow screens.  An internal water mixing system was installed to decrease water age and improve quality of water entering the distribution system. The facility is eligible for listing on the National Register of Historic Places by the Washington State Department of Archaeology and Historic Preservation. Services also included permitting assistance to evaluate the context of the improvements to assess any potential historical resource impacts and coordinating with FAA and FCC agencies for lighting and cellular antenna needs.
