Wetland mitigation question
Posted on 8/20/25 at 11:16 pm

Has anyone on here have any experience say with a camp. I have a 50x120 lot on Grand Isle and need the mitigation to do anything with the lot. I was told by site guy that the Corp of Engineers will let you mitigate on your own property. So in effect My lot would be 50x60 useable and the rest sinks into the back bay. If GI is sinking why do they make it so hard to develop a lot in a semi subdivision?

I have no idea what the rules are for grand isle, but could you do an amount of mitigation elsewhere and use that credit towards the construction on your lot?

Because the idea is to stop development to preserve wetlands (i.e. inflate the value of existing landlords).

GI is a barrier island its not sinking its migrating! The marsh around the island is sinking.
quote:
Barrier islands naturally migrate, primarily landward, in response to rising sea levels and other factors. This migration occurs as sand is transported from the ocean side to the bay side of the island, effectively shifting the island's position over time. Several processes contribute to this migration, including inlet formation, overwash, and eolian (wind) transport.
By the way the rising sea level part is BS. Wind energy moves sand along wave action. Sea level rise at a rate of 1mm per year has negligible change on the rate of migration. This is an example of politics infiltrating science.
Sorry I don't have experience with mitigation other than to say you will have to restore an equal amount of area that is disturbed by your project or buy the credits. The credits have to be purchased from a land bank in the same watershed as your project which means if you buy credits it will likely be from a land bank in Jefferson Parish. Its been 15 years since I was involved in Coastal projects so the regs have likely changed along the way.

Pretty sure you’ll have to get FEMA to change its flood zoning as well

You need someone who is fluent with wetland mitigation, and is not at the Corp. They know the ins and outs, what will work and won't work, and they have a relationship with the people who have the authority to approve or deny your application. Chances are if you get them involved it will be approved.
I used them and lit was worth every penny. I had everything done start to finish in 8 months. Usually it takes a year or longer. Also, you have a stronger likelihood of getting approved using an expert than if you did it yourself.

I could be wrong but I thought mitigation use to be a 2 for 1 swap. Meaning for every acre you wanted to remove you had to create/protect 2 acres somewhere else.

It can be 1:1 it’s dependent on the quality of the habitat you’re disturbing and the quality of the habitat of the mitigation bank you’re buying from.

Address your issues with the Department of Natural Resources Office of Coastal Management. You can start familiarizing yourself with the process in link provided. DNR is actually really helpful and they're pretty happy to answer all your questions and lend assistance.

I think it actually is a 3 for 1 swap. I could be wrong but I heard that is the standard. You are doing more good than harm by mitigating.
Mitigating wetlands is not a “let’s destroy the environment program and fill wetlands.” The overall ecosystem of the state improves when you mitigate. And it’s all paid for the guy applying for it, not the taxpayer. Win.

In your case a mitigation site won’t be allowed at your property. You will be required to purchase credits from a prescribed bank. You’re affecting marsh (herbaceous) so it’ll be a similar habitat you’re buying from the bank.
When someone does their own mitigation you are responsible for its success and maintenance thereif for many years, 20 plus
Look on aerial maps at adjacent lots to see when others built their camps. Go ask them the process and what the costs were. The old number was $65000 per acre, so figure out your amount of acreage impact to get a ballpark estimate.
