DESCRIPTION
Significant changes
have occurred along the nearshore of the Ediz Hook Drift Cell following removal
of two dams on the Elwha River within the past ten years. Dramatic increases in
sediment transport have restored the drift cell on the west side of Port
Angeles where the City's industrial water line is located. It is now covered by
sediment. This has raised the question of whether continued armoring along the
bluffside water pipeline is needed or whether more environmentally friendly
practices could be used which would better enhance bluff health.
The continued increase of sediment flow through the Elwha
Drift Cell also raises the issue of whether more environmental friendly practices
and restoration approaches at the roadway along Ediz Hook is in order rather
than ongoing nourishment program which prohibits sediment recruitment and is
detrimental to salmon. A shift to a more restorative approach could result in
significant habitat improvements benefitting both endangered salmon and forage
fish.
It makes sense to
conduct a comprehensive feasibility study of the entire drift cell between Dry
Creek and Ediz Hook including a nearshore sediment budget to inform future
restoration options. The City is
required to regularly perform beach nourishment in front of the bluff which
does not account for the changed conditions.
Because both locations significantly impact the health of
endangered salmon and also involve important and strategic infrastructure, the
time is right for a feasibility study which assesses the current situation and
then explores various restoration possibilities. This use of scientific
assessment is particularly important to inform discussions with citizens, local
and federal government representatives and other stakeholders.
