Seawalls and Bulkheads at Ocean Shores: What's Actually Permittable

Washington's Shoreline Management Act: Permit-Based, Not an Outright Ban

Washington's Shoreline Management Act (SMA), enacted in 1971 (RCW 90.58), governs development along the state's marine and lake shorelines, including seawalls, bulkheads, and other hard armoring structures. Rather than a flat statewide prohibition on new hard structures the way Oregon's 1967 Beach Bill effectively bans new oceanfront seawalls, or North Carolina's long-standing statewide hard-structure ban does, Washington requires a Shoreline Substantial Development Permit (or, depending on scope, a simpler shoreline exemption) for shoreline armoring, administered locally under a Shoreline Master Program that each city or county develops and the Washington Department of Ecology reviews and approves.

That permit-based structure means a new bulkhead or seawall in Washington is not automatically illegal the way it would be for new oceanfront construction in Oregon or North Carolina -- but it is also not a simple, guaranteed approval. Current state guidance and many local Shoreline Master Programs require demonstrating genuine need (typically evidence of an eroding bank actively threatening a structure, not simply a desire for erosion protection preemptively) and require considering soft-shore or non-structural alternatives before a hard armoring permit will be approved.

Ocean Shores' Own Shoreline Master Program and Grays Harbor County Rules

Because the Shoreline Management Act is implemented locally, the specific rules that apply to a shoreline armoring project on a given Ocean Shores parcel depend on the City of Ocean Shores' own adopted Shoreline Master Program (for property within city limits) working within the framework set by the Washington Department of Ecology. This page did not independently pull the full current text of Ocean Shores' Shoreline Master Program, and it does not state specific current setback distances, permitted structure types, or approval criteria as settled fact. A property owner considering shoreline armoring work should contact the City of Ocean Shores Community Development Department directly for the current, specific rules that apply to a given parcel.

Work below the ordinary high-water mark, or work that could affect fish habitat -- a real consideration along both the open Pacific shoreline and the Grays Harbor-facing side of the peninsula -- also typically requires a separate Hydraulic Project Approval (HPA) from the Washington Department of Fish and Wildlife, layered on top of any local shoreline permit. This is a genuinely multi-agency permitting process for open-water shoreline work, not a single city permit application.

Soft-Shore Preference: Living Shorelines and Bioengineering

Consistent with a broader shift in Washington shoreline policy over the past couple of decades, current state and many local guidance documents explicitly favor soft-shore protection methods -- native vegetation, engineered log structures, beach nourishment, and other bioengineering approaches -- over traditional hard concrete or rock bulkheads and seawalls, because hard structures can accelerate erosion on adjacent unprotected shoreline and degrade nearshore habitat, a well-documented pattern in coastal engineering generally. For a property owner facing genuine erosion risk, this means a soft-shore alternative may be evaluated as a required first option, or at minimum a strongly preferred one, before a hard-armoring permit is likely to be approved -- not merely offered as a suggestion.

Canal and Lake Bulkheads: A Different, More Common Situation

Ocean Shores' extensive interior canal and Duck Lake system operates under a meaningfully different practical reality than open-Pacific oceanfront shoreline. Bulkheads along the Grand Canal, its connecting finger canals, and Duck Lake itself are common and generally more routinely permittable than open-coast oceanfront armoring, because these are calmer, lower-energy freshwater shorelines rather than direct-wave-action ocean coastline, and much of the canal system's edge was engineered with some form of bank stabilization from the outset of the 1960s dredging project. That said, any bulkhead work here still falls under the same Shoreline Management Act permitting framework and may still require a Hydraulic Project Approval from Washington Fish and Wildlife given the canal system's connection to Grays Harbor and its function as fish and wildlife habitat.

This page does not state current specific permitting timelines or cost estimates for a canal-front bulkhead repair or replacement project. Confirm current requirements and typical timelines directly with the City of Ocean Shores Community Development Department before planning a specific project.

What This Means for an Oceanfront vs. Canal-Front Buyer

For an oceanfront buyer specifically concerned about this town's documented shoreline erosion (covered on this site's Beach Erosion Reality page), a new hard seawall is not automatically off the table the way it would be in Oregon or North Carolina, but it is a genuinely permit-intensive, multi-agency process that requires demonstrating real, active erosion threat and considering soft-shore alternatives first -- not a simple construction decision an owner can make unilaterally with a contractor and a checkbook. Erosion protection at the community level continues to depend significantly on the Army Corps' North Jetty maintenance and rehabilitation, covered on the Beach Erosion Reality page, rather than purely on individual property owners' ability to armor their own shoreline.

For a canal-front or Duck Lake-front buyer, bulkhead work is a more routine, more commonly permitted proposition given the calmer freshwater shoreline conditions -- still requiring permits, but generally a more straightforward process than open-coast armoring. Either way, confirm the current permitting requirements and any recent Shoreline Master Program updates directly with the City of Ocean Shores before assuming a specific shoreline project is straightforward.

What This Page Doesn't Cover

This page explains Washington's permit-based Shoreline Management Act framework and how it differs from Oregon's and North Carolina's outright bans on new oceanfront hard structures. It does not state Ocean Shores' current specific Shoreline Master Program setback distances or approval criteria, current permitting timelines or costs, or a technical engineering assessment of whether a soft-shore or hard-armoring approach would be appropriate for a specific parcel. Confirm current legal and regulatory status directly with the City of Ocean Shores Community Development Department, the Washington Department of Ecology, and the Washington Department of Fish and Wildlife before planning any shoreline construction. Nothing on this page is legal, engineering, or permitting advice.
