The average cumulative discounted total cost in $2021-millions for each retreat approach (A) and beach area gained (B) under each retreat approach are displayed over time. Both all-at-once retreat approaches (all-at-once-XA and all-at-once-CE) are highlighted here due to their wide ranges, whereas ranges for threshold-based and reactive retreat approaches are much smaller and similar. Parcel area eroded indicates sand dune land that is lost under SLR-CE.
