What to expect the first time you deal with wetland permitting

Why this catches so many people off guard

Anyone buying or building on land for the first time tends to assume wetland review is a checkbox, something an engineer handles in a week or two. It is not. Wetland permitting touches federal, state, and sometimes local agencies at the same time, and each one asks different questions. If this is your first project, the goal is not to become an expert. The goal is to understand the sequence well enough that you are never the reason things stall.

Step one: figure out if you actually have a wetland

Before anything else, someone needs to determine whether the property has jurisdictional wetlands or waters on it. This is not a guess based on how the land looks. A wetland delineation is a formal study, usually done by a qualified biologist or environmental consultant, that checks three things: the plants growing there, the soil type, and how water moves and sits on the site across the year.

This step alone can take a full growing season if the agency wants to see conditions at different times of year. Budget for that timeline early. Trying to compress it usually just means redoing it later.

Step two: know which agencies you are dealing with

Once a delineation confirms wetlands are present, you are typically looking at some combination of:

• The Army Corps of Engineers, for federal Clean Water Act permits
• Your state's environmental or water resources agency
• Local planning or public works departments, depending on the jurisdiction

Each agency has its own application, its own review timeline, and its own definition of what counts as an acceptable impact. A project that clears federal review can still stall at the state level. First-timers often assume one approval covers everything. It does not.

Step three: understand your options if you cannot avoid the wetland

Most projects start with a simple instruction from regulators: avoid the wetland if you can. If you genuinely cannot, because of lot size, access, or the way the parcel is shaped, the next question is how you offset the impact. This is where wetland mitigation banking comes in. Instead of trying to create a small replacement wetland on your own site, which often fails ecologically, a developer can purchase credits from an established mitigation bank that has already preserved or restored wetland acreage elsewhere in the same watershed.

Chris Vrame, a real estate developer based in Sacramento, California who was among the first in the U.S. to establish a wetland mitigation bank, works in exactly this part of the process. His experience points to a pattern worth knowing: mitigation banking exists because it is often more ecologically sound, and more predictable for a developer's schedule, than trying to build a replacement wetland from scratch on a tight site.

Step four: build in review time you did not plan for

Agencies ask follow-up questions. Almost always. A delineation report comes back and someone wants more data on a specific corner of the property. A mitigation plan gets kicked back because the ratio of credits doesn't match the impact. None of this means something went wrong. It means the process is working as designed. The mistake first-time applicants make is treating the initial submission date as the finish line. Treat it as the start of a conversation instead.

Common mistakes worth avoiding

Assuming a dry-looking property has no wetlands. Seasonal wetlands can be bone dry for most of the year and still be jurisdictional.

Hiring a consultant only after buying the land. A pre-purchase wetland assessment, even an informal one, can save you from a parcel that will never pencil out once mitigation costs are added.

Underestimating mitigation costs in your budget. Credit prices vary by watershed and by how much demand there is for credits in that area. Get a real quote, not an estimate from a similar project somewhere else.

Going it alone on agency communication. A consultant who talks with the Corps or the state agency regularly usually knows what a reviewer will flag before it becomes a problem.

What good preparation looks like

Before you submit anything, have the delineation done, have a rough mitigation strategy in mind, and have a consultant who has worked with the specific agencies reviewing your project. None of this guarantees a fast approval. It does mean you will spend your review time answering real questions instead of fixing avoidable gaps in your application.
