Potential Restoration Actions

In 2010, PSNERP developed conceptual designs for 36 potential restoration projects.  These projects (actions) were identified using the Nearshore Database, a database of known project ideas throughout Puget Sound.  Crossing this database with our spatial data that identifies areas where process-based restoration is likely to be successful, resulted in this list of actions.  Each action is associated with a local restoration organization that serves as the project proponent and liaison to PSNERP. If you have questions or concerns about a project, please contact us.

Design Alternatives (Full and Partial)

Two alternative designs were developed for each of the 36 actions.  One design is a “full” restoration alternative.  This alternative:

dot Describes the maximum opportunity that a site could offer, absent most typical constraints.
dot Assumes the continued existence of major, durable infrastructure (e.g. railroads, utilities, and highways).
dot In most cases, goes well beyond the project proponent’s original description for the proposed project.
dot Provides an understanding of the full restoration potential so that we know what we may be giving up if we proceed with a reduced design.

A second, or “partial” restoration alternative was developed and is often a scaled back version of the full alternative that:

dot Addresses site-specific constraints and other interests at the site.
dot Includes additional elements (e.g. trails, boat launches, public access) that are necessary to satisfy local proponent requirements.

How were projects identified?

PSNERP compared a database of over 700 project ideas to our strategic restoration and protection guidance to identify projects with the best opportunities to protect and restore natural process in the Puget Sound nearshore.


What’s next?

Designs will undergo a thorough evaluation of costs and benefits using the conceptual design as a guide.  PSNERP will work with project proponents, willing landowners, and affected communities to refine designs and advance cost-effective actions forward to implementation.
