Building or repairing a seawall in Michigan is not a project you can start without paperwork. State and local regulations protect Michigan's 3,200 miles of Great Lakes shoreline, and nearly every seawall project requires at least one permit before a single pile goes into the ground. Skipping the permitting process can result in fines, forced removal of your structure, and costly legal headaches.

This guide breaks down exactly what permits you need, which agencies are involved, what the process looks like, and how long it typically takes. Whether you are planning a brand new seawall, replacing a failing structure, or making repairs to an existing one, understanding the permitting landscape will save you time and money.

The Main Permit: Michigan EGLE

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) is the primary regulatory body for shoreline construction. Their Water Resources Division issues permits under Part 301 (Inland Lakes and Streams) and Part 325 (Great Lakes Submerged Lands) of the Natural Resources and Environmental Protection Act.

If your property is on Lake Michigan, Lake Huron, Lake Superior, Lake Erie, or any connecting waterway, you will need an EGLE permit. This applies to new construction, major repairs, and replacements. Even adding riprap or boulder protection along your waterline falls under EGLE's jurisdiction.

What EGLE Evaluates

EGLE reviews several factors when evaluating your application. They look at the environmental impact on fish and wildlife habitat, the effect on neighboring properties and public trust lands, whether the proposed structure is the minimum size necessary, and whether the design follows accepted engineering practices. Projects that significantly alter the natural shoreline or extend into navigable waters face more scrutiny than straightforward repair work.

EGLE Permit Types for Seawall Projects

EGLE offers a few different permit tracks depending on the scope of your project. Minor projects like small repairs or maintenance on existing structures may qualify for a General Permit, which has a faster turnaround. Larger projects, new installations, and anything involving significant changes to the shoreline typically require an Individual Permit, which involves a more detailed review.

General Permits are processed in roughly 30 to 60 days. Individual Permits take longer, usually 90 to 120 days, sometimes more if public comments or additional environmental review is triggered. Application fees range from $100 for minor work to $2,000 or more for complex projects.

U.S. Army Corps of Engineers Permits

In addition to the state permit, many seawall projects on Great Lakes shorelines also require a federal permit from the U.S. Army Corps of Engineers (USACE). The Corps regulates work in navigable waters under Section 10 of the Rivers and Harbors Act and Section 404 of the Clean Water Act.

The good news is that Michigan has a joint application process. You submit one application, and EGLE forwards the relevant portions to the USACE Detroit District office. This eliminates the need for separate federal paperwork in most cases. However, the federal review adds time. Plan for an additional 30 to 60 days beyond the state timeline if your project requires Corps involvement.

Projects that only involve work above the ordinary high-water mark may not require a Corps permit, but this determination should be made carefully. If you are unsure, a qualified contractor can assess your situation during the initial project consultation.

Local Township and County Requirements

State and federal permits are not the only hurdles. Most Michigan counties and townships have their own zoning ordinances that apply to waterfront construction. These local requirements vary significantly from one jurisdiction to another.

Common local requirements include setback restrictions from the water's edge, height limitations for shoreline structures, lot coverage maximums, and construction noise or time-of-day restrictions. Some communities along Lake Michigan have overlay districts with additional rules for properties within a certain distance of the shoreline.

In the Grand Rapids area, for example, properties near inland lakes fall under different local rules than properties along the Lake Michigan coast near Muskegon or Holland. Traverse City and the surrounding Leelanau County have their own set of environmental overlay zones that add another layer of review.

Contact your local planning or zoning office before finalizing your project plans. A zoning compliance check typically costs nothing and takes a few days.

When Permits Are Required vs. When They Are Not

Not every piece of work on your shoreline requires a full permit. Understanding the difference can save weeks of waiting.

Typically Requires a Permit

New seawall or bulkhead construction, complete replacement of an existing structure, extending or raising an existing seawall, placing new riprap or boulder revetment below the ordinary high-water mark, and any work that involves dredging or filling in a waterway all require permits.

May Not Require a Full Permit

Minor maintenance and repair work on an existing permitted structure, replacing individual damaged panels or sheets with the same material and dimensions, and vegetation management above the waterline may not require a full permit. However, EGLE still recommends contacting them before starting any work near the waterline. A quick phone call can confirm whether your specific project needs a permit or qualifies for an exemption.

The Permit Application Process Step by Step

Step 1: Site Assessment. Before you can apply, you need a clear understanding of your site conditions, including soil type, water depth, existing structures, and property boundaries. A professional contractor will evaluate these factors and help determine the best approach for your project. This is where material decisions are made, whether that is vinyl, composite, or steel, or an engineered system like Redi-Rock outcropping.

Step 2: Prepare the Application. The EGLE Joint Permit Application requires detailed project plans, including a site map, cross-sectional drawings, a description of materials, and an explanation of the project's purpose. Photographs of the existing conditions are also required. Incomplete applications are the number one cause of delays.

Step 3: Submit and Pay Fees. Applications can be submitted online through EGLE's MiWaters portal or by mail. Fees are due at submission. Processing begins once your application is deemed complete.

Step 4: Agency Review. EGLE and, if applicable, the USACE review your plans. They may request additional information, suggest modifications, or schedule a site visit. Some projects trigger a public notice period where neighboring property owners can submit comments.

Step 5: Permit Issuance. Once approved, you receive your permit with specific conditions. These conditions might include construction timing restrictions (many projects are limited to certain months to protect fish spawning), erosion control requirements during construction, and post-construction reporting.

Common Permitting Mistakes to Avoid

Property owners frequently run into avoidable problems during the permitting process. The most common mistake is starting work without permits. EGLE takes enforcement seriously, and unpermitted structures can be ordered removed at the owner's expense.

Another common issue is submitting incomplete applications. Missing drawings, unclear project descriptions, or outdated surveys cause EGLE to send your application back, resetting the review clock. Working with an experienced contractor who has been through the process dozens of times prevents these delays.

Failing to coordinate with neighbors is also a frequent problem. If your seawall project might affect drainage, wave patterns, or access for adjacent property owners, addressing those concerns early avoids formal objections during the public comment period.

How Long Does the Entire Process Take?

From initial site assessment to breaking ground, most Michigan seawall projects take 3 to 6 months to move through permitting. Simple repair projects with General Permits can move faster, sometimes in as little as 6 to 8 weeks. Complex new installations with Individual Permits and federal involvement may take 6 months or longer.

The best strategy is to start the permitting process well before your ideal construction window. If you want construction to happen in late spring or summer, begin the permit application process in fall or early winter. Michigan's construction season for shoreline work is typically April through November, with peak activity in summer when water conditions are most favorable.

How Much Do Permits Cost?

Permit costs are a small fraction of total project expense but worth budgeting for. EGLE application fees range from $100 to $2,500 depending on project complexity. Local zoning review fees are typically $50 to $200. If your project requires a professional survey or engineering drawings, those can add $1,500 to $5,000. Environmental assessments, when required, run $2,000 to $10,000. You can find more detail on overall project budgets in our Michigan seawall cost guide.
