Wetland delineation Michigan: wetland delineation cost, EGLE identification fees and the permit bill that follows

A wetland delineation in Michigan costs about $2,500 to $4,500 on a parcel under two acres, $4,000 to $6,000 at five acres and $6,000 to $14,000 at 10 to 20 acres, plus $1,200 to $4,000 if a surveyor has to tie the flags to your property lines. The state sells its own versions. EGLE's Wetland Identification Program charges $500 for the first acre and $250 for each additional acre to find the wetlands itself (sites up to 5 acres), and it will check a consultant's flagged line for a base fee of $500. Either way, the answer that is binding for three years is the finding that an area is not a regulated wetland.

If you are buying or building in Michigan, the part that costs real money is usually not the delineation. It is the calendar. EGLE holds Wetland Identification applications that arrive from October through winter until about mid-April, because nobody can read soils and plants under snow. A site that goes under contract in November with a 60 day inspection period cannot get a state wetland answer in time. That is why most buyers hire a private delineator, and why the timing of the order matters more than the price.

How much does a wetland delineation cost in Michigan?

Consultant pricing in Michigan follows the rest of the Midwest: acreage, access, and how much of the site sits in a transition zone where the delineator has to dig soil pits and record plant plots closely. What is particular to Michigan is the menu of state services that sit next to the private work, and the permit fees you pay if the line lands where you wanted to build.

The consultant ranges are market ranges, not a fee schedule; the EGLE figures come from administrative rule R 281.924 and the permit fees from MCL 324.30306. On a Level 2 identification the arithmetic is simple: 1 acre is $500, 3 acres is $1,000 and 5 acres, the program's limit, is $1,500. If EGLE's Level 3 review finds substantial errors in a consultant's flags, you pay half the original fee again for the second look, which is a good reason to hire someone whose lines EGLE has seen before.

EGLE Wetland Identification Program or a private delineator: which should I order?

Order a private delineator when you have a deadline, more than 5 acres, or winter in between. Order EGLE when you have time, a small site, and you want a state finding you can rely on. Many buyers do both: a consultant flags the line in the spring, then EGLE reviews it under Level 3 so the non-wetland areas carry the state's three year guarantee.

The asymmetry in the third row surprises people. A WIP report tells you in detail where the wetlands are, but under MCL 324.30321 the part EGLE is bound by is the finding that an area is not wetland. That is still the piece a buyer wants: it is the land you can build on without a Part 303 permit for three years from the assessment. If you disagree with the report, the request for a reassessment is due no later than 60 days after you receive it.

Is every wet spot on a Michigan parcel regulated?

No. Since 2018 PA 631 took effect in March 2019, a wetland is regulated by the state only if it is a water of the United States, is contiguous to the Great Lakes, Lake St. Clair, an inland lake or pond, or a stream, is more than 5 acres, has a documented endangered or threatened species, or is one of 17 listed rare and imperiled wetland types such as a prairie fen or a Great Lakes marsh.

Contiguous has a measured meaning in the rules: within 500 feet of an inland lake, pond or stream, or within 1,000 feet of the Great Lakes or Lake St. Clair. That is a distance a surveyor can put on a drawing, and it is often the whole question on a small parcel. A 0.6 acre wet corner 700 feet from the nearest stream, with no rare type and no listed species, can be outside state jurisdiction. The same corner 400 feet from the stream is regulated. Before you pay for a full delineation of a small isolated wetland, ask the consultant to check the contiguity distance first.

Two cautions. Local units of government may regulate wetlands under 5 acres by ordinance, and where one does, it decides its own permits within 90 days. And the federal question does not disappear because the state one does. Michigan runs the Section 404 program itself, but the Corps of Engineers kept jurisdiction over navigable waters and Rivers and Harbors Act waters, and a site near one of those needs both answers.

Why Michigan permits go through one office

Michigan is one of only a few states that administers Clean Water Act Section 404 itself; it took the program over in 1984. For most projects that means one wetland permit application, filed with EGLE, gets you both state and federal authorization. Projects that affect an acre or more of wetland also get a federal review of the state file. For you as a buyer, the practical effect is that EGLE's view of the line is the one that matters for almost every inland site, which is another argument for a Level 3 review of the consultant's flags.

The permit clock is set in statute: 90 days on a Part 303 application, or 150 days if a public hearing is held, and anyone may request a hearing within 20 days. Build that into a purchase agreement before you sign it. If the wetland contingency and the permit window do not fit inside the inspection period, get the extension in writing and signed by both parties before the original date runs out, not after.

What happens if you fill a wetland without a permit?

The fines are large enough that a delineation is cheap insurance. Under MCL 324.30316 a court can impose a civil fine of up to $10,000 per day of violation and order the fill removed and the wetland restored. A willful or reckless permit violation carries $2,500 to $25,000 per day and up to a year in jail, and a repeat violation is a felony with fines up to $50,000 per day. An after-the-fact permit, if one is available at all, costs twice the normal fee. Buyers inherit these problems: if the previous owner filled a wet corner, a delineation before closing is how you find out.

Who can do a wetland delineation in Michigan?

Anyone, legally, which is exactly why you need to vet them. EGLE publishes a list of wetland consultants, but its own page says consultants "are not certified, licensed, or bonded," that the list is not a recommendation, and that any firm that asks to be included is added without review of qualifications. Virginia is the only state that licenses delineators; Michigan does not.

So ask three questions. Has EGLE reviewed this firm's lines under Level 3, and how often did they pass? Which regional supplement will they use? Michigan follows the 1987 Corps manual with the Midwest supplement in parts of Hillsdale, Lenawee, Washtenaw, Livingston, Wayne and Oakland counties and the Northcentral and Northeast supplement everywhere else, and a report that cites the wrong one is a report you will pay to redo. And who will locate the flags: the delineator with a hand-held GPS, or a licensed land surveyor? Our wetland delineation services page covers how to vet credentials in more detail.

Do I need a surveyor as well as a wetland consultant?

You do whenever the line decides where something gets built. The consultant finds and flags the boundary; a licensed land surveyor measures the flags and draws them on the same plan as your property lines, setbacks and proposed building. That surveyed plat is what an engineer designs against and what a lender or township reviewer can read. On a subdivision, a condominium or anything near a setback, a flag line sketched on an aerial photo will not survive review. Budget $1,200 to $4,000 for the survey, and ask for it in the same visit window so the flags are still standing.

A worked example: 4 acres in Livingston County with a wet low corner

A builder has 4 acres under contract in April, with a 60 day inspection period. The low corner is wet, about 450 feet from a creek. Because the corner is within 500 feet of a stream, it is likely contiguous and regulated, so the builder cannot skip the question.

• Private delineation and report (Livingston County is split between the Midwest and the Northcentral and Northeast supplements, so confirm which one the consultant will use): about $4,000 to $5,500, flagged within two to three weeks.
• Surveyed plat of the flags against the boundary and the proposed lots: $1,500 to $3,000.
• Optional EGLE Level 3 review for the three year non-wetland guarantee: $500 base plus the per-acre charges.
• If the lot layout avoids the wetland: no Part 303 permit, and the project moves on.
• If a driveway crossing clips it: a minor project permit at $100 or a larger one at $500, on a 90 day clock.

Total to a decision: roughly $6,000 to $9,000 and about five weeks. Compare that with finding the wetland after closing, when the only options are a redesign or a permit you now need before you can build.

Common questions

How long is a Michigan wetland determination good for?

An EGLE Wetland Identification Program report is binding on EGLE for three years from the date of the assessment for the areas it finds are not wetland. A private delineation has no set validity on its own; it is evidence, and reviewers get uneasy with field data more than a growing season or two old.

How much does EGLE charge for a wetland identification?

For a Level 2 identification, where EGLE staff find the wetlands, the fee is $500 for 1 acre or less and $250 for each additional acre, on sites up to 5 acres, so $1,500 at the maximum. A Level 3 review of a consultant's line costs $500 plus $50 per wetland acre and $20 per non-wetland acre.

Can I get a wetland delineation in winter in Michigan?

Not from EGLE: WIP applications received from October through winter are held until about mid-April. A private delineator can sometimes finish late in the fall, but snow cover and frozen soil stop the field work. If you are buying in winter, write the delineation into the contract as a spring contingency.

Where this fits in your project

A Michigan wetland answer is two jobs: a consultant who flags the line and a surveyor who puts it on your plan. For the national price picture see our wetland delineation cost guide, and for a neighboring state with a very different fee structure compare wetland delineation in Wisconsin. When you are ready to price the survey side, describe the parcel once and up to 3 licensed land surveyors covering your county will send a written land survey quote, usually within 24 hours.
