Environmental permitting is the sequence of surveys, agency consultations and authorizations a project needs before ground can be disturbed. On most Texas projects it runs from early constraints work through to post-construction restoration, and the cost of it is set almost entirely by when you start.
That last part is the whole argument of this article. The permitting work itself does not change much. What changes is how many options you still have when you begin it.
We have been doing this in Texas since 2002, mostly for oil and gas, utilities, municipalities and land development. Here is the sequence, what each stage actually involves, and where projects lose time.
What is environmental permitting?
It is the process of identifying which regulated resources your project affects, consulting the agencies that protect them, and obtaining written authorization to proceed. The resources are usually waters and wetlands, water quality, floodplains, protected species, and cultural or historic sites.
It is not one permit. It is a set of parallel tracks that have to converge before you break ground, and each track has its own agency, its own timeline and its own way of going wrong.
What are the stages of environmental permitting?
Seven, in rough order. Stages two through four usually overlap.
| Stage | What happens | Why projects lose time here |
|---|---|---|
| 1. Constraints analysis | Desktop review of aerials, soils, hydrology, floodplains, species range and known cultural sites to find what might be regulated | Skipped entirely, so nobody knows what they’re dealing with until the design is fixed |
| 2. Field surveys | Wetland delineation, protected species habitat evaluations, presence/absence surveys, cultural resources survey | Missed the survey season for specific species, or field surveys run in the wrong season or conditions, so results get questioned or have to be repeated |
| 3. Agency consultation | Corps, US Fish and Wildlife Service, NOAA Fisheries, state agencies, municipalities, federal land managers, tribal and historic preservation offices | Consultation started late, or not at all. Surveys get completed and submitted, then the agency asks for data that could have been collected during the original surveys if consultation had not been an afterthought |
| 4. Permit application | Section 404/10 authorization, state water quality certification, and any project-specific permits | An incomplete or incorrect permit application, which restarts the clock rather than pausing it |
| 5. Mitigation | Avoid, minimize, then compensate for what’s left through bank credits or permittee-responsible mitigation | Treated as a line item rather than a design constraint, when avoidance is almost always cheaper |
| 6. Construction monitoring | Environmental inspection, erosion and sediment control, contractor coordination, agency liaison | Nobody on site who understands the permits or can answer an inspector’s question, so small issues escalate |
| 7. Restoration and closeout | Site restoration, seeding and planting, final reporting, permit closeout | Left incomplete, which leaves the permit open and the obligation live |
Which permits and consultations might you need?
It depends what your project touches. Most projects need some combination of the following.
- Section 404/10 authorization from the US Army Corps of Engineers, for any discharge of dredged or fill material into Waters of the United States. This is the one most projects turn on, and we go into it in depth in Section 404 permits.
- Section 401 water quality certification from the state, which runs alongside the 404 and can carry its own conditions.
- Section 7 consultation or a Section 10 incidental take permit under the Endangered Species Act, where project impacts affect federally protected species. Section 7 runs through the agencies. Section 10 runs through you. Either way it means additional work, money and time that your project probably cannot afford.
- Section 106 review under the National Historic Preservation Act, covering archaeological and historic resources, coordinated through the state historic preservation office and, where relevant, tribes.
- NEPA documentation where there is a federal nexus, which can range from a categorical exclusion to an environmental assessment to a full environmental impact statement.
- Migratory Bird Treaty Act considerations, which usually show up as constraints on when you can clear vegetation rather than as a permit.
- Section 9 authorization from the US Coast Guard for work affecting navigable waters, on the projects where it applies.
- State and local requirements, which vary and do not disappear because a feature falls outside federal jurisdiction.
You do not get to pick which of these apply. The project picks, based on what it crosses or impacts. The only real choice is whether you find out early or late.
One more thing worth saying plainly. The permits and the regulations are in flux right now, more than ever. It is imperative to have someone on the team who is up to date, and ideally who has close contacts at the agencies.
Nationwide permit or individual permit?
A nationwide permit covers categories of activity with minimal impacts and moves relatively quickly. An individual permit is for projects with potentially significant impacts and involves public notice, comment and a full alternatives analysis.
| Nationwide permit | Individual permit | |
|---|---|---|
| Covers | Defined categories of activity with minimal individual and cumulative effects | Projects with potentially significant impacts, or anything outside the nationwide categories |
| Review | Verification against the permit’s terms, often with a pre-construction notification to the district | Public notice, public comment, alternatives analysis under the 404(b)(1) Guidelines, public interest review |
| Typical timeline | 3 to 6 months, longer if the project is high visibility or has public opposition | 1 to 2 years |
| Practical effect | Design to stay within the thresholds and you keep your schedule | Budget the time from the start, because it cannot be compressed later |
The standards by which both permits are evaluated are worth understanding, because they shape the design work. No discharge can be permitted if a practicable alternative exists that is less damaging to the aquatic environment, or if the nation’s waters would be significantly degraded. You have to show you avoided what you could, minimized what you could not avoid, and compensated for the rest. In that order.
That sequence is why avoidance is a design decision and not a permitting decision. By the time the application is written, the chance to avoid has usually passed.
What changed with the 2026 nationwide permits?
The Corps reissued the nationwide permits in January 2026. There are now 57 of them, they took effect on 15 March 2026, and they run through 15 March 2031.
The substance did not change much. The Corps described the 2026 permits as having no major changes from 2021, with clarifications rather than overhauls. One new permit was added, NWP 60, covering work to improve passage for fish and other aquatic organisms. NWP 56 for finfish mariculture was not reissued.
For a project starting now, this is background rather than news. We covered the reissuance in detail when it happened, in 2026 Nationwide Wetland Permit Reissuance.
Why does starting early cost less?
Because early permitting buys options, and late permitting buys paperwork.
A constraints analysis during due diligence tells you where the regulated features are while you can still move a pad, shift an alignment, or decide the site is not worth it. The same information after the design is fixed tells you what you now have to permit and mitigate.
The work is nearly identical. What differs is what you can do with the answer.
The pattern we see repeatedly: a project team treats environmental as a box to check before construction, without any real grasp of what counts as an environmental “hurdle”, then discovers a drainage nobody mapped, and finds that avoiding it would mean redesigning work that is already engineered and bid. So they permit it and mitigate it instead. That is a real cost, and it was avoidable for the price of a conversation months earlier.
Almost every expensive environmental problem we get called into was knowable earlier and cheaper to solve then. Not for a bigger budget. For an earlier one.
How long does environmental permitting take?
Anywhere from a couple of months to well over a year, depending on which authorization you need and which Corps district you are in.
Two things drive the range more than anything else.
The type of authorization. A nationwide permit verification and an individual permit are different orders of magnitude, and the difference is usually decided by your design rather than by your paperwork.
The district. Every Corps district runs its own workload, staffing and interpretation of marginal features. A file that moves in one district can sit in another. Knowing what a district expects to see, and knowing the people reviewing it, is a real part of how quickly you get an answer. That is not a shortcut, it is just fewer rounds of correction.
The number developers most often underestimate is the time it takes to obtain an approved jurisdictional determination. In our experience that has been running six to ten months, and it sits at the front of everything else.
What does environmental permitting cost?
It varies with project complexity, agency response, and how much impact you can avoid. We have done nationwide permits on simple 10 acre tracts, free of endangered species and cultural issues, for as little as $20,000. The same tract with species or cultural issues to address has run as high as $75,000.
Individual permits have no ceiling. The process, the reporting requirements and the unforeseen hoops can easily push one north of $100,000, and that is before mitigation. Avoiding an individual permit is usually the largest single cost decision on a project, and it gets made in the design rather than in the application.
The variables are the same ones that set the cost of a wetland delineation: how much is already known before anyone mobilizes, how hard the ground is to work, how many regulated features the project touches, and whether the project can stay out of them.
Who handles all of this?
Either your team, a consultant, or some uncomfortable combination discovered halfway through.
The value of a consultant here is not filling in forms. It is knowing which of the tracks above actually apply to your project, running them in parallel instead of in series, and producing submissions a district accepts the first time.
We do this end to end: constraints analysis, wetland delineation, protected species surveys, cultural resources, agency coordination, permitting, mitigation planning, construction inspection, erosion and sediment control, and site restoration. One firm across the whole sequence, which means nothing gets dropped in a handoff between three vendors.
We also put senior staff on the work and train junior staff underneath them. The cheapest submission you can buy is the one that comes back for revision.
Frequently asked questions
When should environmental permitting start?
During due diligence or early design, before the layout is fixed. That is when the findings can still change the design, which is the only point at which avoiding an impact is cheaper than permitting it.
What’s the difference between a nationwide permit and an individual permit?
A nationwide permit authorizes categories of activity with minimal impacts and is verified against set terms. An individual permit is for projects with potentially significant impacts and requires public notice, comment and an alternatives analysis. The nationwide route is substantially faster where a project qualifies.
Do the 2026 nationwide permits affect a project I already permitted?
Possibly. If your activity was authorized under a 2021 nationwide permit and had commenced or was under contract by 14 March 2026, you have until 14 March 2027 to complete it. If it had not started by then, you need authorization under the 2026 permits.
Do I still need a permit if the feature isn’t federally regulated?
Sometimes. A feature falling outside federal jurisdiction after the 2023 change to the definition of waters of the United States does not automatically make it unregulated. State and local rules still apply and they vary.
What does environmental permitting cost?
It varies with project complexity, agency response, and how much impact you can avoid. A simple 10 acre tract on a nationwide permit, free of endangered species and cultural issues, has run as low as $20,000. The same tract with species or cultural issues to address has run as high as $75,000. Individual permits have no ceiling and can go north of $100,000 before mitigation, which is why avoiding one is usually worth designing for.
Can permitting run at the same time as design?
It should. Constraints work and field surveys inform the design, and agency consultation can run while engineering continues. Running them in sequence rather than parallel is one of the most common causes of a blown schedule.
