Puget Sound’s 2,500 miles of shoreline are among the most valuable and fragile of our natural resources. A dynamic area where land and marine ecosystems meet, the shoreline is constantly changing with the action of wind, waves, tides, and erosion. These same shaping forces are also the reason why people often build bulkheads or other structures to harden the shoreline. Indeed, more than 25% of the shoreline has been armored to protect public and private property, ports and marinas, roads and railways, and other uses.
Shoreline armoring, the practice of constructing bulkheads (also known as seawalls) and rock revetments, disrupts the natural process of erosion, which supplies much of the sand and gravel that forms and maintains our beaches. Erosion also creates habitat for herring, surf smelt, salmon, and many other species in Puget Sound. Over time, shoreline armoring may cause once sandy beaches to become rocky and sediment starved, making them inhospitable to many of our native species.
The Kitsap Regional Shoreline Restoration Program is an effort to protect and restore the Puget Sound nearshore by supporting willing landowners who wish to remove bulkheads on their shorelines. The Kitsap Regional Shoreline Restoration Program was funded by Environmental Protection Agency’s (EPA) Puget Sound Watershed Assistance Program, Grant #PO-00J08501-0.
The Puget Sound Ecosystem Monitoring Program (PSEMP) is an independent program established by state and federal statute to monitor environmental conditions in Puget Sound.

The projects were conducted between 2011-2015 with support from the EPA's National Estuary Program. The report is an analysis of findings on shoreline restoration and derelict net and fishing gear removal.
A new peer-reviewed study reports significant findings on the impacts of shoreline armoring in the Salish Sea.
Bulkhead removal is becoming an attractive option for many shoreline property owners as awareness spreads of their geological and ecological impacts, and as aging bulkheads come up for replacement. New state guidelines provide alternatives to hard armor.
For more than a hundred years, property owners have seen shoreline erosion as the enemy. But it turns out that in many cases erosion is actually a good thing — crucial, according to scientists — because it provides the sand and gravel needed for healthy beaches.
A significant number of Puget Sound property owners have been altering their shorelines without required permits. A new report suggests that state and local regulators should increase enforcement and make penalties more costly for violators.
By removing bulkheads where they can, property owners are improving shoreline habitat, one piece at a time. Officials from county and nonprofit groups have been offering assistance and finding new ways to connect with property owners.

Where shoreline bulkheads remain in place, the loss of spawning habitat used by surf smelt is likely to reach 80 percent.
Rising sea levels are expected to exacerbate habitat loss caused by bulkheads, according to studies in the San Juan Islands.
The removal of shoreline armoring in Puget Sound has become a priority for state and federal agencies, but until recently there have been relatively few scientific studies of armoring's local impact. New research looks at the pronounced biological and ecological effects of these common shoreline structures, especially for tiny beach-dwelling creatures that make up the base of the food web.
A 2015 report from the University of Washington Puget Sound Institute summarizes and reviews 14 EPA-funded projects focusing on Puget Sound's marine and nearshore environments. The projects were conducted between 2011-2015 with support from the EPA's National Estuary Program.
The 2015 Puget Sound Fact Book brings together statistics and other information about the health and makeup of the Puget Sound ecosystem. Areas of focus include climate change, geography, water quality, habitats, human dimensions and regional species. The fact book was prepared for the Encyclopedia of Puget Sound with funding from the Environmental Protection Agency and the Puget Sound Partnership.
Conservation and ecology of marine forage fishes— Proceedings of a research symposium, September 2012
The symposium was held on September 12–14, 2012, at the University of Washington, Friday Harbor Laboratories campus. Sixty scientists, graduate students, and fisheries policy experts convened; showcasing ongoing research, conservation, and management efforts targeting forage fish from regional and national perspectives.
By the end of 2010, the PSP Science Panel’s efforts had reached the stage where an independent review by the WSAS (Washington State Academy of Sciences) was timely and useful to help guide its future indicator development efforts.

In the 2009 State of the Sound report, the Partnership 1) documents the current status of the ecosystem, 2) explains the performance management system we are putting in place to manage recovery efforts in a systematic way and our progress to date in developing the system, and 3) presents an overview of funding and anticipated results for the 2009-11 biennium, as well as accomplishments in 2007-09 biennium.
The 1994 Puget Sound Update—the fifth annual summary report of this program—evaluates the data collected by the PSAMP in 1993 (the most recent year for which the data have undergone quality assurance review and interpretation) and compares these data to past information on Puget Sound.
This seventh Puget Sound Update is based primarily on the findings of the Puget Sound Ambient Monitoring Program (PSAMP). The PSAMP is a long-term effort to investigate environmental trends, improve decision-making and prevent overlaps and duplication in monitoring efforts. The results of the PSAMP are supplemented by the findings of many other efforts to evaluate the condition of Puget Sound’s waters, sediments, nearshore habitats and biological resources.
This Puget Sound Update is the eighth report of the Puget Sound Ambient Monitoring Program (PSAMP) since the program was initiated in 1988 by the State of Washington.
The Washington Department of Fish and Wildlife has published a comprehensive set of guidelines for managing shoreline development such as bulkheads and seawalls.
The Shoreline Monitoring Toolbox standardizes approaches to tracking the status and health of shoreline environments in Puget Sound.
The decaying seawall along Seattle’s waterfront is providing scientists with an opportunity to improve long-lost habitat for migrating salmon. It could also show the way for habitat enhancements to crumbling infrastructure worldwide. One University of Washington researcher describes the project.
Scientists say eelgrass, an unassuming flowering plant found just off shore in Puget Sound, is vital to the health of the ecosystem. They also say the plant is declining. New and increasingly urgent efforts to restore it brought a group of researchers to the 2014 Salish Sea Ecosystem Conference.

The State of Our Watersheds Report is produced by the treaty tribes of western Washington, and seeks to present a comprehensive view of 20 watersheds in the Puget Sound region and the major issues that are impacting habitat.
The Tulalip reservation is located near Marysville, Washington. It was created after the Point Elliott Treaty of 1855, and currently has a population of 2,500 members. The entire tribal population is approximately 4,000 and growing.
Tulalip Tribes Area of Concern:
In the course of building homes, businesses, roads, and infrastructure, the lands and waters of Puget Sound have been drastically modified. Levees, dams, and toxic deposits are obvious and have site-specific impacts. But less obvious are the cumulative changes from human land use activities, such as bulkheads, docks, permanent removal of native vegetation, and loss of native habitat in marine and upland areas. These activities have damaged the underlying processes that form beaches, keep rivers, estuaries, and forests healthy, and support species. Historically, the actions that led to ecosystem degradation were intended to improve the quality of life for Puget Sound residents, but with closed shellfish beds, flooding, species decline, and other impacts it is clear that ecosystem rebuilding efforts are needed.
More then 700 miles of Puget Sound shoreline is considered to be "armored," and as much as four miles of new armoring is added each year.
Puget Sound has over 4,000 km (2,500 miles) of shorelines, ranging from rocky sea cliffs to coastal bluffs and river deltas. The exchange of water, sediment, and nutrients between the land and sea is fundamental to the formation and maintenance of an array of critical habitat types.
