Answer:
When a government embarks on an intentional, purposeful, calculated relocation of people and buildings away from risks, this is usually referred to as a Managed retreat.
This is usually carried out due to the presence of hazardous conditions such as the prevalence of wildfire, flood, earthquakes, wildfire, or drought.
Managed retreat strategies are usually accompained by allowing the shoreline to retreat naturally. The disadvantage of this is that land is lost and soon there will be the need for another retreat each time costing the government a lot of resources.
A more feasible option (in some cases) would be to execute "Hard Engineering"
This involves the construction man-made civil structures which try to control natural processes.
