For the exhibition, Inundation, Christina Gerhardt initiated the HighWaterLine iteration in Honolulu and together with Adele Balderston they co-organized three talks and two walks for the Kaka‘ako neighborhood. The walks and talks offered an opportunity to experience the historical flow of water in the Kaka‘ako area, once a wetlands area with many fresh water springs, and to talk about current and future flooding, watershed management and development in the area.
