Overstromingsrisico van de haven van San Francisco

De Port koos Arcadis voor het leiden van een onderzoek naar methoden die de pieren zouden helpen de stijging van de zeespiegel en de overstromingen te weerstaan. Een belangrijke overweging: het integreren van overstromingsbestendige maatregelen in herstelprojecten voor de pieren.

• Deploying watertight defenses on the outside of the building to block water
  
  
  
• Retrofitting furnishings with flood resistant materials and allow flooding to occur
  
  
  
• Raising the building’s floor by several feet to be above flood levels
  
  
  
• Installing a permanent raised flood barrier on the outside edge of the pier structure
  
  
  
• Activating a temporary raised flood barrier on the outside edge of the pier structure
  
  
  
• Using floating breakwaters to weaken waves before reaching the pier structure
  
  
  
• Protecting critical building systems (water, wastewater, drainage, gas, electrical, etc.) from harm
  

The proposed resiliency measures are intended to protect the existing structures from flood risk over a substantial portion of this century, reduce the amount of construction needed on the structures, lessen the disruption to the historic waterfront area, and limit the capital costs needed to rehabilitate the underused piers.
