Some things about the future of the Central Waterfront are clear . The 2001 Nisqually earthquake revealed that the Alaskan Way Viaduct is unsound and the seawall is in very poor condition . Another earthquake could cause liquefaction of the soils , undermining the viaduct and placing massive pressure on the seawall . While there may be much question as to what will happen , there is no doubt that things can not remain as they are . Elsewhere on the waterfront , the deteriorating Piers 62 and 63 also can not remain as they are
