Beach renourishment

With sea levels rising, renourishment of beaches has become a billion dollar per year industry.  What is this process and when is it a good investment?

Beach erosion is replaced by dredging sand typically from offshore to renourish the beach.  The process is costly several million dollars per mile on the typical shorefront.  With sea level rising at 3.2 mm/year this puts more and more pressure on beaches; which means more beaches need renourishing and the new sand may not endure.  Thirty years ago there was one renourished beach, Miami Beach.  Today on the east coast there are not many major beaches that have not been renourished.  A list with costs is provided by Western Carolina University. Below are some visual examples or renourished beaches.  The key to determining if it is a good investment is:

  • What is the duration of the repaired beach?
  • Does it prevent damage?
  • Value of real estate it protects?

  1. Renouishment of beaches is the process in which outside companies come in to basically “restore” the beach by replacing the erosion. They do this by pumping in sand from another source, usually an offshore source. It is a good investment if the duration of the restoration is short, if it will help prevent future damages, and if the real estate surrounding the damaged area is valuable. A good example of a beach who made a good investment by renourishing is Venice Beach, Florida. Their investment was good because the beach is valuable to both residents and tourists, meaning that the state of Florida will continue to get good revenue out of the beach by renourishing it.

  2. I never knew it was so much money to renourish a beach until I read this. Seven million dollars per mile is a lot and I’m surprised that with our economy, how we could afford the resources needed. Also with all of the tropical storms happening, I do not see why we even bother to help renourish the beaches if the storms push shorelines back thousands of feet on top of sea level rising 3.4 mm/year.

  3. Beach nourishment is when sand is moved back onto a beach from offshore resources to replace sand that has washed away. It is a good investment to beaches that have a high economic flow or have high value development that need to be protected. Long island is a good example because it draws millions of dollars in revenue to the area and has millions of dollars of development on the coastline that needs to be protected.

  5. Renourishment is the process of adding sand to a damaged or small beach to make it wider and to add dune restoration and protection to the area. In my opinion, beach renourishment is a good investment fifty percent of the time. In the video above about the Allen Harbor renourishment project, the beach was destroyed after only thirteen months. However, in the other video above about New Jersey and Hurricane Sandy, the renourishment and the addition of dunes did work to protect the beach and surrounding homes. Because you can never predict how powerful a storm is going to be, you can never really know if this process is a good investment. In terms of my beach, Nags Head, North Carolina, they did complete a renourishment project in 2011, but the beach was sadly destroyed by Hurricane Matthew in 2016. So there is really no definitive answer to classify renourishment as a good investment because with each storm, the damage and result will differ.

  6. I was surprised by the cost and the process of beach renourishment. As I watched the Cancun video I became more intrigued by the amount of effort it takes to push the sand onto the beaches and smooth it out. The cost is what is most surprising, along with funding the cost to this enormous project. The time that it takes makes sense because they need to constantly move the tubes, reconnect them, and drain the sand from the ocean every so many feet. I am curious how long ago the last beach renourishment was before they renourished it in the Cancun video because they added several feet, maybe even yards to the beach. The damage rate for each storm will differ so it is hard to tell when and how often you should renourish beaches, but when the dunes and sand become scares, it will be a good time to think about this hefty project.

  7. Renourishment of beaches is very important when it comes to protecting beaches and communities when big storms arrive. Like they were doing in New Jersey after the hurricane, they built up dunes and are adding more sand to protect the beach and the area surrounding it more next time. Beach renourishment is when they bring new sand in from somewhere else to replenish the beach that has been damaged or that lost a lot of sand space. Although it is costly, it is necessary to perform beach renourishment to keep the beaches in healthy condition and also to protect them from storms. It is even more necessary after a big storm to help revive the beach from what it had lost.

  9. Beach renourishment is one of those topics that could go either way. In the case of some beaches it is completely necessary as residents and businesses have their homes and jobs there. In the example of Miami Beach, it is completely necessary to continue nourishing that beach. Too many people depend on it for it to just keep getting eroded. Other areas that get hit frequently with storms and are constantly being destroyed, raises a question on if its worth it to renourish the beach. In my opinion at the end of the day, you have to see if there will be more benefit by renourishing the beach or will it be more of a loss.

  10. Beach renourishment is when beach erosion is replaced by dredging sand that is brought in from off-shore. For the process, it costs several million dollars per mile on the shore front. I think the renourishment of beaches is a good investment if the money brought in from the local economy outweighs the cost to renourish the beach. Fenwick Island, Delaware shelled out $4.5 million for an emergency renourishment in 2011 but keeping the beach in function lets million of tourists visit the area annually.

  11. The process of renourishment is when sand is brought in from an offshore location, to a beach that has a lot of erosion. Renourishment is a good investment when the duration of the project is short, when it will help prevent future damages, and it helps protect the estate value. An example of a good investment of renourishment was with Fort Myers Beach, Florida. They have done two renourishment projects since 2010, this has been able to keep Fort Myers Beach a popular destination choice by both tourists and Florida residents. By doing the projects they are able to keep people coming back and keep them happy.

  12. Beach renourishment is when sand is added to a damaged or small beach. It is an extremely expensive process, so why do it? A beach could be helping prevent damage to other structures behind it. If the beach is not renourished it will disappear, thus causing damage to the land and real estate behind it. It also depends on the value of the real estate it is protecting. For example, the beach I had to look at for the equilibrium project was Westhampton Beach of NY. The renourishment spent was around $120 million. This is a lot of money but was worth it because the homes on the beach were million dollar homes.

  13. Beach renourishment is import to protect not only the beaches about also the community civilizations when large storms, flooding, and swell occur. Different strategies for renourishment are building beach dunes and adding more sand to the beach. Typically the sand is brought from a different location to help a damaged beach that may have experienced a lot of shore-line-retreat. The downfall is that renourishment of beaches is extremely costly.

  14. Although beach renourishment may be a very costly project, it is well worth it for those dwelling around it, including plants, animals, and human beings, as well as being necessary for the beach itself. Without renourishment we may lose many of our most cherished beaches overtime meaning losing it’s land along with it. With beaches receding so much per year, this mending process is essential to maintaining our land as is, and the infrastructure surrounding it. Sometimes, maintaining the environment is more important than maintaining our wallets.

  15. Beach renourishment is when sand is brought in from an offshore location, to a beach that has a lot of erosion. Renourishment is a good investment because it will help prevent future damages from storms and erosion but also it protects properties near the beach. An example of a good investment of renourishment was Jacksonville beach, Florida, the beach i was assigned for the last project. The beach grew in size and so did the Dunes. The dunes growing will protect the properties and the beaches. By doing this properties will hold their value and tourist will continue to come in the area.

It is a good investment when the length of the restoration does not take up too much time, when the beach needs help with preventing future damages and especially if the land or real estate that surrounds the damage areas on the beach is worth something or is valuable.Beach renourishment is truly a process. I did not expect it to cost as much as it does. I am still not sure if I think renourishing a beach is worth it when after another major natural disaster it will just be destroyed again.

  17. Beach nourishment is the process of dumping or pumping sand from elsewhere onto an eroding shoreline to create a new beach or to widen the existing beach. This does not stop erosion but just give the erosional forces something to bang on for a while. Beach nourishment is an investment when the property and valuable things the beach front is protecting is in danger of being damaged. It is also worth nourishment when the beach is publicly funded and the general public will have good access to the restored beach rather than only a few beachfront property owners benefitting. An example of renourishment being a smart investment was during Hurricane Sandy in 2012. The Jersey Shore was completely ruined and there needed to renourishment up and down the coast. The Jersey Shore is a popular tourist for both in state and out of state. A huge value to many people.

  22. With the sea levels rising and all the different factors that can affect and cause storm surges, beach nourishment need to be a priority. It is important to replace sand that was blown away of covered by the new tides because the beaches need to be in beach equilibrium. According to the Sandy video of the beach being renourished the dunes helped protect that beach from the storm so as a part of beach renourishment they should create dunes on the beach to protect against future storms. The process may be expensive but if they act quickly and spend the time doing it now the right way it could save money in the long run by not having to do it again to that beach for a while.

  24. Beach renourishment, although costly, is important. According to the video about LBI in New Jersey, there were areas of the beach that had been renourished, as well as areas that had not. Due to the renourishment process that had taken place before Hurricane Sandy, the renourished areas of the beach fared much better than those that were not renourished. That being said, renourishing beaches is really a shot in the dark, as weather changes may destroy all the progress, or the beaches may thrive for a long time.

  25. Beach nourishment is the process of refilling a beach with the proper amount of sand needed to restore the shore line. This can be done by using large pumping mechanisms to expand beaches back to where they once were with large quantities of sand. Highly publicized beach areas such as cape cod would be a good example of a good investment in the beach nourishment argument. With high traffic and revenue attracted to this area, the money would not be going to waste.

  28. Beach nourishment is the process of dredging sand from the middle of the ocean and bringing it back to the beach. This will not only expand the beach but also will protect the people behind it from the ocean itself. This is a good investment when the beach is getting dangerously low. This will be caused from over time or from a natural disaster. One example of a natural disaster causing the beaches to disappear is the most recent one, hurricane Irma. Looking at pictures of the aftermath in the Keys in Florida these beaches will need to be re-nourished or else they will be under water in no time. The next storm will cause the ocean to rise over the beaches with no problem.

  30. Beach re nourishment is the process of beach erosion getting replaced by sand that is brought from off shore. For some beaches, it is necessary for this process to occur because people live and have businesses on the beachfront. The Miami Beach case is an example of a beach definitely needing nourishment because too many people depend on the beach. In general, you should analyze the situation and ask yourself if the nourishment will benefit the beach and the use of it, or if it will be a waste of money.

  31. Beach renourishment, is the process where they remove sand from the ocean through a pipe line, and pump it onto the beach. They don’t need to pump it from the ocean, but its cheeper than buying it from a sand company. When pumping the sand on the beach, they are trying to stop water from heading inland. Adding more sand will stop the water, and will save them millions in the long run. If water gets inland, it will destroy everything in its path, costing millions, maybe even billions.

  35. 8. For the purpose of the Town’s project, beach nourishment is the process by which sand is brought by a dredge from offshore sand sources and pumped onto a beach. The sand is placed according to an engineered plan with a specific criteria for a built beach (berm) and storm protection. During a beach nourishment project, large volumes of beach-quality sand, called beach fill, are added from outside sources to restore an eroding beach. Or, a beach is constructed where only a small beach, or no beach, existed. Ultimately, beach nourishment widens a beach and advances the shoreline seaward. To say whether or not this is worth it or not really depends on the areas. You need to way the possible benefits from doing this. Which could include revenue extra beach space would bring in or protection from future storms. Different areas are more necessary then others but it all depends on the circumstance for that particular beach.
