The East End Shoal is an exploration of the dynamics between land, water, geology and the users of the Eastern Promenade. The design of the East End Shoal is an extension of the Promenade terrain and deliberately preserves views of Casco Bay by placing the programmatic uses beneath the extruded landform – a landform informed by geologic faults and folds found in the area.
The raised landform provides shelter for park visitors as well as creating a tunnel event for the Narrow Gauge Railroad. The earth formed reinforced concrete shell combined with vertical and sloping granite faces of the structure should provide the community with a low maintenance facility that should last well into the next century. Protruding granite blocks in the sloped surface will act as wave deflectors to dissipate the surf energy during a nor’easter. Using reclaimed excavated material from simultaneous construction projects on the peninsula the East End Shoal will divert waste from being transported to off peninsula disposal sites.
