Created for a waterfront site in Boston’s Seaport District, this design manipulates the flow of tidal water to create multiple macro-scale rhythms, or a tidal hypermeter to borrow the musical term. Two stepped platforms enclose a beach while maintaining important pedestrian pathways to the Boston ICA. Ocean water flows through a channel under the northern platform onto the beach, which tilts to orient flow perpendicular to the main steps. This slow flow is punctuated by water rushing into the channels cutting across the beach every half hour. Visitors are immersed in a tactile experience with the tides and the birds, crustaceans, and kelp thriving in the intertidal zone.
