As sea levels rise, engineers are using massive Dutch-inspired sand sculptures to protect shorefront settlements…It’s called the “sand motor,” and it comes from the Netherlands, a low-lying nation with centuries of experience in coastal protection…
Tens of millions of dollars pour into the state each year to fund beach replenishment efforts ..
“…we are doing it with the intent of preserving the economic usefulness of oceanfront properties that are being threatened by erosion and shoreline migration, sea-level rise and storm waves and so forth…That methodology (used by the U.S. Army Corps of Engineers) is flawed because it uses property value to determine the benefits of nourishment and our belief is that our property values aren’t the correct way to assess the utilization or return on public funds. A better way of doing that is looking at what are the public benefits.”

Sea Isle City approved a $3.2 million funding package Tuesday to pay for its share of a beach replenishment project that will restore parts of its eroded shoreline with 640,000 cubic yards of fresh sand…(that) is part of a $33.7 million project by the U.S. Army Corps of Engineers that will include replenishing the storm-damaged beaches and dunes in the southern end of Ocean City and Strathmere…
More than $2.6 billion has been spent dumping sand onto the Jersey Shore. Was it worth it?
Waves lap up against the narrow shore of North Wildwood as Patrick Rosenello straightens his sunglasses, and leans against the steel seawall, the soft sand crumbling beneath his tan dress shoes.
Quiet as he is, the mayor doesn’t have to utter a word about how important the tiny specks of sediment are to the resort town. His navy sweater vest says it all.
The municipality’s seal features two dolphins flanking the phrase “Sun and Sand.”
Carlsbad considers joining other coastal cities in yet another sand replenishment project – the San Diego Union-Tribune
SANDAG asked Carlsbad to shoulder a proportional share of the $200,000 cost for a planning, feasibility and economic analysis needed to start the project, which would pull sand from the ocean and spread it on beaches from Oceanside to Imperial Beach….
UPDATE: The City Council unanimously opposed actively participating in the City of Oceanside’s sand nourishment pilot project during its April 11 meeting, remaining opposed to any plans that may obstruct the natural flow of sand down the San Diego County coastline.
However, the Carlsbad City Council agreed to request a city staffer be present during the neighboring city’s proposed pilot project meetings and design competitions…
The Federal Government has agreed to a major beach restoration project in Orange County to restore almost 2 million cubic feet of sand lost to storm erosion over the past several years.
The sand will be dredged from the sea and added to replenish the coastline from Seal Beach to Bolsa Chica to Huntington Beach and as far as the Newport Beach Pier.
“We’re experiencing a large amount of receding of sand into the ocean,” said Kevin Pearsall, State Parks Superintendent.
The project will help protect property and roads from flooding. Seal Beach saw flooding in January.
“It’s nerve wracking that they have to do that, but time erodes everything,” said Colleen Walsh, a Bolsa Chica resident…
There have been several recent proposals and some projects actually underway to grind up glass bottles and use this ground glass to replenish beaches. Along most shorelines, other than in tropical environments, the dominant mineral making up the beach sand is quartz, which is silicon dioxide (SiO2), the same elemental composition as glass. While this may initially seem like a good solution for replenishing or nourishing disappearing or narrow beaches, this concept is not a sustainable or effective approach.
Initially derived from silica sand glass is a valuable resource that is already in a pure form that can most effectively be recycled or melted down to make more glass, rather than being put on the beach where it will be lost to the ocean over time as it is carried offshore or alongshore…
Use of Pulverized Recycled Glass for Beach Nourishment: A Review – Georgia Coastal Research Council (GCRC)
This paper reviews geotechnical, biological, and abiotic analyses conducted on the experimental placement of recycled glass on beaches in Florida. It will also describe the experiences local governments have had when considering the use of recycled glass as an alternative material for beach nourishment.
Coastal erosion caused by increased extreme weather events and sea level rise is escalating the rate and extent to which beaches are washing away. Traditionally, inland and offshore sand and dredged material from rivers, canals, and the ocean have been used to nourish beaches, but these resources are becoming increasingly expensive and difficult to obtain…
The rise of curbside recycling programs over the past few decades has meant more glass recycling. But for a long time, many recycling centers didn’t have the technology to turn recycled glass into the raw material for new bottles. Instead, recycled glass often wound up being used as a cheap construction material, or even to cover landfills.
Now, with new technology that can better sort glass collected in curbside recycling, more used glass bottles can be turned back into new glass bottles. To see how this works, we went to a glass recycling facility and a bottle factory…
Outside a recycling plant in Jersey City, N.J., there are piles and piles of what looks like garbage.
But it’s actually broken glass…
