Building drains with outlets.
Reason: Proper drainage (e.g., subsurface drains or French drains) safely channels groundwater away, lowering water pressure and flow through soils and preventing subsurface piping and erosion. The other options either address surface/wave erosion (breakwaters), can worsen problems (compaction), or increase erosion risk (steeper banks).
