Schematic Design through Construction Document
After completing an EIR in 1997-1998, EBMUD secured an interim water supply, emptied the water, and trenched for earthquake faults beneath the old Berryman Reservoir. Trenching showed that fault traces ran through most of the site, underscoring its seismic vulnerability and forcing the replacement tank into the northwest corner, the area closest to regular public access. In 2008, EBMUD selected the team of Muller & Caulfield Architects and Dillingham Associates to complete the community process and revise and finalize the design concept. Many neighborhood residents have views that include the site. Residents were initially very concerned about the tank design, prompting over 50 to attend our first public meeting. Using a three dimensional site model created with ArchiCAD, we showed the public a new 2.6 MG tank in this location with several different roof options. We explained the reasons for the tank size and elevation, planting lists, and tank color and construction. Ultimately, our visualizations and explanations convinced the public that the new tank would be relatively unobtrusive.
