Beach Replenishment

Beaches are dynamic, not static. Sand particles are always moving, with the alignment rearranged by wind and water. Large storms can erode a beach completely, or deposit a new sand spit. A quarter of Virginia's shoreline is eroding, and some sites in Virginia are losing land at a rate of 30 feet per year.1

Bulkheads, jetties, and "living shorelines" can alter the movement of sand temporarily. Beach replenishment is another temporary solution. Replenishment projects are based upon the assumption that after storms move sand, humans can pump/dump sand to restore the beach.

Future storms will move the sand again, and fuure replenishment projects will rebuild the beach again. Rather than fight the natural flow of sand, local/state/Federal budgets set aside funds to pay for regular replenishment.

After Superstorm Sandy in 2012, the beach in the Ocean View neighborhood of Norfolk was replenished. The Corps of Engineers dredged sand from the Thimble Shoal shipping channel, pumped it onto the Ocean View beach, and spread the sand with bulldozers. The objective was to build a beach 60' wide and 5' high at the landward edge.

Norfolk had tried to maintain the width of the beach by constructing 36 rock breakwaters. Those trapped sand moving along the shoreline, but also disqualified Ocean View from Federal beach replenishment programs. The regulations were revised after Superstorm Sandy.

Congress appropriated $12.9 million and Norfolk contributed $5.5 million for the first replenishment stage, which was completed in 2017. As reported in The Virginian-Pilot:2

Under the agreement, every nine years for the next 50 years the sand that washes away will be replaced. Those renourishment efforts are expected to cost $7.5 million each, with Norfolk's share pegged at $2.2 million.

The total $34.5 million dredging and beach building project planned to place 1.2 million cubic yards of sand onto Ocean View. The first phase revealeed that some parcels that would be affected wre not publicly owned. The city researched deeds and acquired private beachfront parcels. In 2022, Norfolk purchased an eight-acre parcel that Ballard Fish & Oyster Company had owned since 1938.

The property was vacant and the company's clam/oyster farming (Cherrystone Aqua-Farms) was done on the Eastern Shore, but public ownership ensured that the next beach restoration effort at Ocean View could proceed without objection by a private property owner.3
