ABSTRACT
In this chapter, the planning and implementation process of hybrid tsunami mitigation in the Sendai coastal plain after the 2011 Japan earthquake are both extracted and analyzed to examine resilient design for sea level rise. The government adopted a multi-layered tsunami risk reduction approach based on a combination of managed retreat and green-grey infrastructure, which have had positive impacts on improving redundancy in tsunami-risk management and regenerating natural ecosystems. One primary challenge, however, remains – how to redesign the relationship between the place and people detached from a coastal settlement. This creates essential interactions for maintaining green infrastructure. Hazards and impacts related to sea level rise differ from those of tsunami, urging landscape architects to develop alternative temporal–spatial designs for sea level rise which place more focus on storing water rather than simply defense strategies against tsunami.
