Since the cranes at the Port of Oakland can be seen from afar due to their size, they have become city icons and symbolize Oakland's economy as a seaport city, industry. Given that the Port is a topic of controversial discussion in sustainability and environmental justice, what if the Port rewrites this relationship by cleaning up the air as well as providing a new sustainability symbol for the city. By creating vegetated towers (to filter the air column), with small footprints because space is highly constrained, uses the concept of power that mimics the cranes while symbolizing a new future. A spiral staircase would create the core of the tower so the plants could be maintained, and plants that only utilize fog from the coast for water would be chosen for planting.
