SUSSEX COUNTY, DE — The burden of rising costs of beach replenishment could land on Delaware’s beach towns. On Thursday evening, the Delaware Department of Natural Resources and Environmental Control (DNREC) presented its recommendations for cost sharing for future beach replenishment projects. The cost of beach replenishment projects is currently covered by the federal government and the state. But, according to DNREC, the replenishment cost is increasing to an unsustainable level.
