A Louisiana Coastal Use Permit is required before you begin any project that will have a direct and significant impact on coastal waters within the state’s coastal zone. The permit is issued by the Office of Coastal Management (OCM) inside the Louisiana Department of Energy and Natural Resources (LDENR), and it covers roughly 20 parishes running from the Intracoastal Waterway south to the Gulf. Most projects that need a state permit also need a federal permit from the U.S. Army Corps of Engineers, and a single Joint Permit Application starts both reviews at once.
Does Your Project Need a Permit
Two questions decide this: is the work inside the coastal zone, and does it count as a regulated activity?
The coastal zone boundary generally follows the southern edge of the Intracoastal Waterway and covers about 20 parishes. Ten of those parishes had their boundaries adjusted in the most recent revision, so an older map may show the line in the wrong place.1Louisiana Department of Energy and Natural Resources. Coastal Zone Boundary 2012 LDENR publishes interactive boundary maps online. If your site sits close to the line or near the Intracoastal, confirm the location with OCM before you spend money on design.
Inside the zone, a permit is triggered when an activity has a “direct and significant impact on coastal waters.” The most common triggers listed in the administrative code are:2Legal Information Institute. Louisiana Administrative Code Title 43 – Rules and Procedures for Coastal Use Permits
- Dredging or filling in coastal waters.
- Siting, building, operating, or maintaining levees.
- Shoreline modification such as bulkheads, breakwaters, and harbor structures.
- Water control structures like weirs and floodgates that change how water moves through wetlands.
The scope is broad. Moving earth, placing structures in wetlands, or changing how water flows through a marsh all fall inside it, whether the applicant is a homeowner building a dock or an energy company installing a pipeline. The final call on whether a specific activity qualifies rests with the LDENR secretary.
Activities That Are Exempt
Louisiana law carves out several categories that do not require a Coastal Use Permit:3Justia. Louisiana Revised Statutes Title 49 RS 49-214.34 – Activities Not Requiring a Coastal Use Permit
- A single-family home or camp built for the owner’s personal use. Subdivisions, speculative building, and multi-family construction do not qualify.
- Normal maintenance and repair of existing, currently serviceable structures, provided the work does not expand the footprint into wetlands, involve dredging or filling, or significantly change what the structure does.
- Agriculture, forestry, and aquaculture on land already used for those purposes.
- Hunting, fishing, and trapping.
- Work done entirely on land five feet or more above mean sea level, unless the secretary finds the specific project would directly and significantly affect coastal waters.
- Any use that does not have a significant impact on coastal waters.
The exemptions have real limits. One home for personal use is exempt; three on spec is not. Maintaining a bulkhead is exempt; extending it further into the marsh is not. If your project sits in a gray area, call OCM before you start. That call is cheaper than an enforcement action later.
General Permits vs. Individual Permits
OCM sorts applications into two tracks.
A general permit (CUP-G) covers routine, low-impact work that OCM has already evaluated as a category, such as small bulkheads and maintenance dredging. If your project fits the predefined criteria, you skip the more intensive review.
An individual permit (CUP-P) applies to anything outside a general permit category or anything with more than minimal environmental effect. That means a full project-specific review, public notice, and possibly a public hearing. Large commercial developments, major dredging, and coastal industrial facilities usually go here.
Some parishes run approved Local Coastal Programs that handle smaller “uses of local concern” through the parish rather than OCM.4Justia. Louisiana Code RS 49-214.25 – Types of Uses
What to File and Where
The Joint Permit Application is a single form that starts both the state review at OCM and the federal review at the Army Corps.5U.S. Army Corps of Engineers New Orleans District. USACE Permits and Permissions Applications are submitted and tracked through OCM’s online system, PermitTrak, which provides real-time status updates.6Louisiana Department of Energy and Natural Resources. PermitTrak System
The application requires a clear description of what you want to do and why, and precise GPS coordinates for the site. Vague location descriptions get bounced. Detailed drawings, called plats, are the core of the package:
- A vicinity map showing the project location relative to recognizable landmarks.
- A plan view showing the horizontal project footprint, with high and low water lines.
- Cross-section drawings showing depth of excavation or height of structures against water and ground elevations.
Label every dimension. Reviewers use the drawings to calculate the area and volume of impact, and missing measurements are one of the most common reasons applications are flagged incomplete.7Justia. Louisiana Revised Statutes Title 49 RS 49-214.30 – Coastal Use Permits You must also identify adjacent property owners, who receive notice during review, and sign a sworn affidavit that you made a reasonable effort to identify all landowners on the property where the work will occur. Forms and instructions are on the LDENR website under the Office of Coastal Management.8Louisiana Department of Energy and Natural Resources. Applying for a Coastal Use Permit
Fees
Application fees are non-refundable and due at filing:9Louisiana Department of Energy and Natural Resources. OCM FAQs
- Residential projects: $20 application fee, plus $0.04 per cubic yard of material dredged or used as fill. The first 125 cubic yards are free, and the total is capped at $2,000.
- Non-residential projects: $100 application fee, plus $0.05 per cubic yard with no minimum and a $5,000 cap.
How Long Review Takes
Statutory deadlines run in stages. Within ten days of receiving your application, the secretary distributes copies to the parish and to state and federal agencies, and public notice is issued. Separately, the department has 14 days (excluding holidays) to decide whether the application is complete. If it isn’t, you get written notice of the deficiencies.7Justia. Louisiana Revised Statutes Title 49 RS 49-214.30 – Coastal Use Permits
Once the application is complete, a decision must come within 60 days. Inside that window, timing depends on whether there is a public hearing. With no hearing, the decision comes within 30 days after public notice. With a hearing, the deadline runs to 15 days after the hearing, whichever is later. Projects that draw opposition or raise environmental concerns often stretch these timelines because OCM may ask for modifications or more information before deciding.7Justia. Louisiana Revised Statutes Title 49 RS 49-214.30 – Coastal Use Permits
An approved permit will carry specific conditions on how the work is done. Those conditions are legally binding, and violating them carries the same penalties as working without a permit.
Compensatory Mitigation
If your project will cause an unavoidable net loss of wetland ecological value, the permit will require compensatory mitigation. The statute is direct: mitigation must be sufficient to replace or substitute for the ecological value lost. The only way around it is to show that mitigation would make the project impractical and that the project serves a clearly overriding public interest.10Louisiana State Legislature. Louisiana Revised Statutes RS 49-214.41
Three options are available, subject to the secretary’s approval:11Legal Information Institute. Louisiana Administrative Code Title 43 – Rules and Procedures for Mitigation
- Design and carry out an individual restoration project yourself.
- Buy credits from an approved wetland mitigation bank.
- Pay into the Louisiana Wetlands Conservation and Restoration Fund.
Section 404 permits require compensatory mitigation as well, with a federal preference for mitigation bank credits over permittee-responsible work. The agencies coordinate on this during review. Projects the secretary finds will produce a net gain in ecological value over their lifetime are exempt from mitigation entirely.10Louisiana State Legislature. Louisiana Revised Statutes RS 49-214.41
Federal Permits That Usually Ride Along
Getting the state permit does not settle the federal side, and vice versa. The Joint Permit Application starts both reviews, but each operates under its own law.
A Clean Water Act Section 404 permit from the Army Corps is required for any discharge of dredged or fill material into waters of the United States, from riprap on a bank to filling a wetland building pad. Exemptions cover normal farming, maintenance of currently serviceable structures, and farm ponds, but those exemptions disappear if the work would convert a wetland to a new use or impair the flow of a waterway.12eCFR. 40 CFR Part 232 – 404 Program Definitions; Exempt Activities Not Requiring 404 Permits
A Rivers and Harbors Act Section 10 permit is required for any structure in or over a navigable waterway, or any work that could alter its course or condition. Docks, piers, bulkheads, boat ramps, and pipelines or power lines crossing navigable waters all trigger it.
Projects that involve a federal permit or federal funding must also certify consistency with Louisiana’s approved Coastal Management Program. If the state objects, it can block the federal permit until the conflict is resolved.13eCFR. Federal Consistency with Approved Coastal Management Programs If a project could affect species listed under the Endangered Species Act, the Corps must consult with NOAA Fisheries or the U.S. Fish and Wildlife Service, and the resulting biological opinion can add significant time and impose conditions.14NOAA Fisheries. Endangered Species Act Section 7 Consultations
Permit Duration and Extensions
A Coastal Use Permit gives you two years to start work and five years from the date of issuance to finish. You can request an extension of up to two additional years to start and up to three additional years to complete.2Legal Information Institute. Louisiana Administrative Code Title 43 – Rules and Procedures for Coastal Use Permits
Extension requests cost $80 and must be filed between 180 and 60 days before the permit expires. A late request can still be considered, but no permitted work may occur past the original expiration date until the extension is granted or a new permit is issued. Missing the deadline without a request effectively kills the permit.2Legal Information Institute. Louisiana Administrative Code Title 43 – Rules and Procedures for Coastal Use Permits
Emergency Work
When a storm, flood, fire, explosion, or spill creates an immediate threat to lives, property, or the environment, you do not need to wait for a permit to take corrective action. Emergency uses are exempt from the advance-permit requirement, but only for work that is immediately necessary to address the emergency.8Louisiana Department of Energy and Natural Resources. Applying for a Coastal Use Permit
Before starting, or as soon as possible after, notify OCM and the Local Coastal Management Program in each affected parish. If OCM confirms the work qualifies, it issues a provisional Emergency Use Authorization. You then have 30 days to submit a complete Joint Permit Application covering all the work performed. If the work does not actually qualify as an emergency response, you may face enforcement action for unpermitted activity.8Louisiana Department of Energy and Natural Resources. Applying for a Coastal Use Permit
Appealing a Denial
If your permit is denied, approved with conditions you object to, or otherwise decided against your interests, you can appeal under RS 49:214.35. The right extends to the applicant, affected local governments, affected agencies, and any person adversely affected by the decision.7Justia. Louisiana Revised Statutes Title 49 RS 49-214.30 – Coastal Use Permits
Federal denials follow a separate track. If the Army Corps denies your Section 404 or Section 10 permit, you can file a Request for Appeal with the division engineer within 60 days of receiving the Notice of Appeal Process. No work can begin in waters of the United States while the appeal is pending.15eCFR. 33 CFR 331.6 – Filing an Appeal
Penalties for Working Without a Permit
Enforcement stacks at both levels, and both can hit at the same time.
On the state side, the secretary can impose an administrative penalty of up to $12,000 per violation, calculated from the ecological value of the affected area, whether you knew you needed a permit, your cooperation with investigators, and the extent of the damage. The secretary can also assess the full cost of environmental restoration and mitigation. Knowing and intentional violations are criminal offenses carrying fines of $100 to $500, up to 90 days in jail, or both, and courts can impose civil liability including restoration costs, damages, and attorney’s fees to the prevailing party.16Justia. Louisiana Revised Statutes Title 49 RS 49-214.36
Federal enforcement under Section 404 is harsher. Civil penalties can reach $68,446 per day per violation for unauthorized discharges into waters of the United States, and the EPA can issue administrative compliance orders requiring you to stop and restore the site to its pre-violation condition.17eCFR. 33 CFR Part 326 – Enforcement Removing unauthorized fill, regrading, and replanting native vegetation typically costs far more than the penalties themselves, and the combination of daily fines and a mandatory restoration order is enough to bankrupt a small project.18U.S. Environmental Protection Agency.
