Erosion is a big problemfor bluffs. Restoring affected wetlands can reduce wave heights and property damage by buffering the velocity and intensity of waves. Although this method of ceasing beach erosion can be very effective, its drawbacks are obvious. Coastal Erosion Additional reasons to avoid structural protective measures include the high costs to install and maintain them, state or local prohibitions against them, their propensity to causeerosion to adjacent beaches and dunes,and the unintended diversion of stormwater and waves onto other properties.
