A stretch of shoreline in south Puget Sound is getting
an extreme makeover thanks to a restoration project
that removed 250 feet of bulkhead, an abandoned house
with a failing septic system and a variety of invasive
shrubs and weeds.
Washington Department of Natural
Resources (DNR) owns the property, located on Weyer
Point north of Olympia in Woodard Bay, and wants
to return it to nature.
Bulkheads and other forms of shoreline
armoring can harm shorelines by preventing bluff
and bank erosion—a natural process that provides
sediments to maintain shoreline habitats. Also, bulkheads
alter wave energy, which creates a scouring action
on the beach in front of the bulkhead and damages
habitat.
Watch what happens
Last fall, crews removed rock, log and concrete bulkheads—all under
the watchful eye of archeologists, geologists and Michele Zukerberg, manager
of DNR’s Woodard Bay restoration project.
While bulkheads have been removed
in several locations around Puget Sound, they’re
usually replaced with soft-shore armoring, or they
require long-term maintenance through manual replenishment
of beach sediments.
Nothing will replace the Weyer Point
bulkheads.
“To my knowledge, simply removing
the bulkheads and watching what happens has never
been done,” Zukerberg said. “So there
is very little information about what might happen
when you take bulkheads away.”
How can you tell if it’s
working?
Before the excavator rumbled to life, Zukerberg
and her colleagues sampled sediments and surveyed
the local sea life to gather baseline data. Results
from this project could have a wide impact on shoreline
armoring issues throughout Puget Sound.
“As the Sound’s landlord,
it is essential for the Department of Natural Resources
to set the standard for stewardship of our marine
resources,” said Brad Ack,
Chair of the Action Team, “This project will
do just that.”
Removing the bulkheads was only one
part of this impressive project. DNR staff and partners
looked for ways to recycle or reuse most of the materials
from the site. Zukerberg calculated that, by weight,
only 13 percent of several hundred tons of material
went into a landfill.
The project was funded by a grant
from the Washington Interagency Committee for Outdoor
Recreation and the FishAmerica / NOAA partnership.
