Habitat Restoration

The Pacific Northwest is ripe with nature’s bounty.

We benefit from fishing, hunting, swimming, hiking, wildlife viewing, and everything else that comes with living alongside nature. Stream or river banks are riparian areas, and the plants that grow there are called riparian vegetation. Riparian vegetation is extremely important because of the many functions it serves.

At the same time, living with nature brings many unique challenges along with it. Flooding, erosion from streams and rivers, beaver damage, and weed infestations are issues that many of us encounter on our properties. Your District’s goal is to equip you with the tools you need to be good stewards of your land and our natural resources, as well as manage some of the challenges that living with nature can bring.

Live Near the Shore?

With support from Snohomish Conservation District and the Department of EcologyWhidbey Island Conservation District developed a guide for homeowners living near or on the shoreline in Washington. You’ll learn about the watershed you live in, as well as actions you can take to protect water resources on your property and in your

Waterfront Living Basics

Puget Sound’s iconic shoreline is something we all get to enjoy, whether we own property that has it or not. That’s why it’s in our best interest to take good care of it in the best way we can. Below are some resources that will help.

Frequently Asked Questions:

The answer to this question depends on your specific site conditions and should involve a site assessment by a shoreline specialist.  If your home is not directly at risk, then it is likely the answer will be “no” – there will be little reason to invest in expensive shoreline interventions such as a bulkhead.  In fact, it will be difficult to get new shoreline armor permitted if it does not directly protect a primary structure such as a home.  Ideally, your shoreline exhibits the typical slow, natural erosion process that supports coastal habitat and functions in Puget Sound.  Whatever the outcome of your shoreline assessment, you will want to make certain that you are not contributing to (or accelerating) erosion problems inadvertently.  Your property management decisions can cause unintended problems with drainage or slope instability.  Understanding how best to manage water and vegetation on your shoreline will limit erosion on your waterfront.

As a basic rule, you benefit the most by keeping as much native vegetation (trees, shrubs and groundcovers) as possible on your waterfront (and on your property as a whole).  Layers of vegetation provide significant water management and slope stabilization services.  Instead of clearing your property and putting in a large lawn to the water’s edge, limit the extent of clearing to the area that you will actually use.  If trees are blocking your view, hire tree care professionals such as certified arborists to prune your trees. You can also plant additional native trees and shrubs in the unused areas of your property to improve water management and slope stability around your home. 

Try the International Society of Arborists, Pacific Northwest Chapter, for certified tree care professionals.

Try the Washington Native Plant Society for year round local sources for Pacific Northwest native plants.

Water often has a huge impact on slope stability.  You want to be certain that your shoreline drainage strategy or irrigation systems are not leaking or contributing to bank instability or erosion.  Drainage management above shoreline slopes can be complex, so we typically recommend using professional guidance to assess and develop a water management strategy that is appropriate for your property.  

Some things to keep in mind: if you have any pipe systems (tight lines, subsurface drains, French or curtain drains, etc.), know exactly where they are.  Monitor them several times each year for leaks or breaks, so you don’t soak extra water into a slope or bluff unintentionally.  Remember that our “natural drainage management systems” are incredibly valuable: our native vegetation provides an incredible service with regard to water management.  Layers of trees, shrubs and groundcovers will intercept, slow down, take up, and evapotranspire rainfall on your property, thus decreasing the amount of runoff that you need to manage.  In contrast, large paved or roof areas and big lawns actually create extra water that you will have to manage in order to avoid contributing to erosion or even slope instability.  

Yes, there are bulkhead alternatives and they are being used more and more often around Puget Sound. When deciding how you will respond to erosion on your waterfront, you will want answers to the following questions… 

  • First, are you certain that you truly need to do something? 
  • Is erosion posing a direct risk to your home, or is it part of the natural process of coastal change and something you can live with? 
  • Why is erosion happening? Is it natural or is it caused by vegetation and drainage management practices?

Is it possible to change upland management before modifying your shoreline? This could be a significantly less expensive and less complex process – as well as better for your property and for the overall health of the Puget Sound. 

Before you make a decision, seek unbiased guidance from a shoreline professional – not just a bulkhead installer.  When possible, consult several coastal professionals before you decide how to respond to erosion on the waterfront.  

If an intervention is necessary to protect a critical structure such as your home, you will also want to find out if bulkhead alternatives are feasible for your specific property.  Site conditions will determine the options available for your unique section of the marine shoreline. 

Characteristics such as bluff conditions, bank height, exposure to open water and wind energy, the surrounding shoreline context, upland conditions, and many other factors determine which options make sense for stabilizing a shoreline.  Again, seek unbiased professional guidance before making a decision.  Learn about the alternatives, their appropriateness for your site, and the timeline involved.  Taking time to learn all you can may save you thousands of dollars in the long run. 

If your shoreline armor can’t be safely removed, you can still contribute to a healthy Puget Sound. 

  • Start with shoreline vegetation: wherever possible, plant natives species that will overhang the shoreline armor and drop food such as insects into the water below. You can select lower-growing species for important view areas, and larger shrubs or trees for the edges.  Remember that birds, insects, and many mammals share the shorelines with us – and with all the sea creatures.
  • Be sure to properly maintain your septic system.
  • Avoid the use of fertilizers and chemicals along Puget Sound’s sensitive shorelines. Landscaping with native plants eliminates the need for fertilizers.

Waterfront impacts vary depending on the specific context of each property, but the cumulative impact of shoreline armor has led to declines in quality habitat for many Puget Sound species.  The type and number of impacts depend on the form of armor involved and the nature of the property.  Potential (and commonly observed) impacts include:

Erosion, which affects

  • The area of dry beach at high tide
  • The area available for recreation
  • Upper beach and backshore
  • Wave reflection, which can undermine the stability of shoreline armor over time
  • Natural retreat of the shoreline, which narrows the remaining available beach
  • Connections between the water and land, which makes access difficult for people and for wildlife

Wildlife, such as

  • The amount of accumulated driftwood and logs and beach wrack (shells, seaweed, etc.) left on the beach at high tide line
  • Available forage fish spawning habitat (herring, sand lance, and surf smelt)
  • The quality of riparian (shoreline vegetation) functions, such as food delivery, wood recruitment, and shelter

Sediment, such as

  • The delivery and reduction of the available sediment moving along the shoreline in the local “drift cell” or littoral cell
  • Drainage patterns to the beach
  • Sediment delivery and transport, which affects the availability of materials that build Puget Sound beaches
  • Sediment movement along the shoreline, which causes localized erosion down-drift
