SLIDE 2

∗ Puget Sound Nearshore General Investigation Study

Goal: Identify nearshore ecosystem problems and develop a portfolio of

solutions to protect and restore Puget Sound

Cost-share between Corps of Engineers and Wash. Dept. of Fish & Wildlife
Many other Partners

 Working for Water Resources Development Act (WRDA) Authorization

Puget Sound Nearshore Ecosystem Restoration Project (PSNERP) Background

SLIDE 3

Puget Sound, Washington

Semi-Enclosed Coastal Sea ∗ Expansive fjord ∗ Large river deltas ∗ Steep coastline with narrow nearshore zone ∗ Mixed sand/gravel beaches ∗ Strong regional gradients

tides, wave exposure, salinity

∗ Ecology strongly linked to geology and physical processes ∗ Diverse shoreline ecosystems ∗ Rich biological resources

Nearshore Ecosystems

The shallow water of estuarine deltas & marine shorelines… From the top of the coastal bank… To water depths where light supports plant growth, and… Up rivers to the end of tidal influence.

Science-Based Problems in Puget Sound

1. Barriers in large river deltas restrict the movement of fresh water and tides.

SLIDE 8

Science-Based Problems in Puget Sound

1. Barriers in large river deltas restrict the movement of fresh water and tides. 2. Small coastal inlets have been blocked

ff and filled in.

Science-Based Problems in Puget Sound

1. Barriers in large river deltas restrict the movement of fresh water and tides. 2. Small coastal inlets have been blocked

ff and filled in.

3. Armoring along beaches and bluffs prevents sand and gravel from replenishing beaches and intertidal areas.

3. Armoring along beaches and bluffs prevents sand and gravel from replenishing beaches and intertidal areas. 4. Nearshore wetlands have been eliminated. 5. The shoreline has become shorter, simpler, and more artificial.

3. Armoring along beaches and bluffs prevents sand and gravel from replenishing beaches and intertidal areas. 4. Nearshore wetlands have been eliminated. 5. The shoreline has become shorter, simpler, and more artificial. 6. Many places are affected by multiple types of changes.

SLIDE 13

1. Restore large river deltas

Reconnect to tides and rivers

2. Restore beaches and spits

Reestablish sediment input, transport

and accretion

3. Restore coastal embayments

Restore shoreline complexity and

length

Remove tidal barriers

4. Improve habitat diversity and connectivity

Solutions for the Puget Sound Nearshore – Restoration Objectives
