Seawalls and Shoreline Armoring in Grand Haven: EGLE's Framework, and the Federal Pier It Doesn't Cover

Michigan Regulates Shoreline Armoring Through EGLE, Not by Default Right

Shore armoring structures -- seawalls, revetments, sandbags, and groins -- are regulated under Michigan's Great Lakes Submerged Lands Program, administered by EGLE (the Department of Environment, Great Lakes, and Energy), with major implications for how shoreline resilience actually gets managed property-by-property along the state's coast. This is a real permitting requirement, not a suggestion: a property owner generally cannot install a seawall, revetment, or similar hard shoreline-protection structure on Great Lakes shoreline without going through this state permitting process first.

EGLE's stated program preference is worth understanding before assuming hard armoring is the default answer to erosion risk: the agency specifically recommends natural shoreline treatments, or bioengineering, over traditional hardened structures, and its own guidance states that new shoreline hardening should generally be avoided where an alternative, softer approach can adequately protect the property. That's a meaningfully different starting posture than some ocean-coast jurisdictions, where hard armoring is more routinely permitted as a first-choice erosion response.

Critical Dune Areas Add a Second Layer of Permitting

For any Grand Haven-area property near a coastal dune, a second regulatory layer applies: Michigan's Critical Dune Areas program, established under Part 353 of the Natural Resources and Environmental Protection Act (NREPA), currently protects roughly 29% of the state's dunes and requires a permit for a range of activities on the lakeward or dune-affected side of a property -- including construction of a new house, an addition, a deck, a driveway, moving sand, and, directly relevant here, construction of a revetment. Adopted in 1989 with strict standards including a general prohibition on construction lakeward of protected dunes, the program's rules were relaxed in 2012, but meaningful permitting requirements remain in force. A Grand Haven-area shoreline lot that sits within a designated Critical Dune Area may face both the general Great Lakes Submerged Lands permitting requirement and this additional Critical Dune Area layer for the same proposed shoreline project.

The Grand Haven Pier: A Federal Structure, Not a Private Seawall

It's worth being explicit about a distinction that's easy to blur: Grand Haven's own iconic pier system is not a private shoreline-armoring structure subject to the private-property permitting framework described above -- it's a federally maintained navigation structure. The U.S. Army Corps of Engineers, Detroit District, maintains the North Pier and the Government Basin as part of its Great Lakes navigation mission, and while the City of Grand Haven owns the South Pier itself, the Corps maintains that structure as well, including a roughly $1 million project that replenished stone at the rubble-mound revetment on the eastern edge of the basin and replaced aging timber fenders on the basin pier structure. The South Pier itself was originally completed in 1893 and runs nearly 1,500 feet, carrying the two 1905 lighthouses and the restored catwalk that make it one of Grand Haven's defining landmarks.

That federal maintenance relationship is genuinely different from what applies to a private homeowner's seawall or revetment a few blocks up the shoreline. A private property owner cannot rely on Army Corps maintenance funding or authority for their own shoreline structure -- they have to go through EGLE's private-property permitting process directly, and bear the full cost of design, permitting, construction, and ongoing maintenance themselves.

Why This Matters More During High-Water Years

The practical stakes of this permitting framework rose sharply during the 2019-2020 record-high-water period covered in more depth on this site's Flood Zones and Beach Erosion pages, when Lake Michigan-Huron hit its highest recorded level since accurate Army Corps records began in 1918. During periods like that, private shoreline property owners facing acute erosion pressure may be tempted toward emergency, unpermitted shoreline hardening -- sandbags, riprap, or other stopgap measures placed without going through EGLE's process first. That carries real regulatory risk (potential violations and required removal) on top of the underlying erosion risk itself, and it's a genuinely important thing to ask about during due diligence on any existing shoreline structure on a property being purchased: was it permitted correctly, and by whom.

What a Buyer Should Actually Do

Before purchasing any Grand Haven-area shoreline property with an existing seawall, revetment, or similar structure, ask directly whether it was permitted through EGLE's Great Lakes Submerged Lands Program and, if applicable, the Critical Dune Areas program under Part 353 -- an unpermitted structure can become the new owner's liability to resolve. Before planning any new shoreline-protection project, contact EGLE directly to understand the current permitting requirements and the agency's stated preference for natural/bioengineered approaches over hard armoring, since that preference may shape what's actually approvable. And keep clear in your own head the real distinction between Grand Haven's federally maintained pier system and any private shoreline structure elsewhere along the coast -- they operate under entirely different maintenance, funding, and regulatory frameworks.
