What the report tells you, by horizon
- Today
Which defended or undefended frontage your address actually sits behind, how far away it is, and the Shoreline Management Plan policy in force right now — hold the line, managed realignment, or no active intervention.
- 2055
Metres of recession projected by the Environment Agency for that frontage, given both with defences maintained and without. This is where the two numbers usually first diverge.
- 2105
The long-term projection, and the long-term SMP policy — which is frequently not the policy today. A frontage held now can be scheduled to stop being held, and that decision is already written down.
