The specter of sea level rise, perpetual drought, and disappearing wetlands has put many sizes and shapes of horizontal levee on the region’s shoreline adaptation maps. What’s next?
Three sites along the East Bay shoreline will demonstrate potential pathways for shoreline adaptation, as part of the San Francisco Bay Trail Risk Assessment and Adaptation Prioritization Plan led by the East Bay Regional Park District. One site called the Northwest Territory, planned as a new district park, will feature a Bay Trail extension around the full extent of Alameda Point.
The Bay Trail connecting Sausalito and Mill Valley is a bustling pathway where recreational bicyclists, bike commuters, and pedestrians all mix amidst the bayfront marsh scenery of the Bothin Marsh Open Space Preserve. Around thirty times per year, though, this scene looks dramatically different, as high tides flood the area with seawater, making the path impassable.
Ten future reconfigurations of a Marin City lagoon, park and highway site subject to flooding came from UC Berkeley students last fall. The students from Dr. Kristina Hill’s class shared their plans with the community and entered a national competition. “Marin City residents want access to nature for their kids, protection from flooding and safe travel in and out of their community. Communities like Marin City should get resilience investments first, because they’ve been underserved historically,” said Hill.
