William & Mary's Virginia Institute of Marine Science, NOAA, the U.S. Army Corps of Engineers and FEMA have joined with representatives from state agencies, non-governmental organizations, academia and private industry to launch a new “community of practice” designed to protect U.S. coastlines.

The partnership promotes a hybrid engineering approach that integrates natural or “green” measures with hard or “gray” structural ones at the landscape scale. The effort is referred to as a “Systems Approach to Geomorphic Engineering,” or SAGE. The goal is to help coastal communities identify more effective and affordable means of coastal protection against an increasing threat of more coastal storms, rising sea level, and fiscal constraints at all levels of government.

The primary portal for SAGE is a one-stop website — http://sagecoast.org — that makes resources readily available to resource managers, community leaders, developers, and the public. The website includes a database describing coastal resilience projects around the nation, including “Living Shorelines” for shoreline stabilization, habitat restoration, and floodplain management. Each project includes a variety of site, design, and partner information. 

Carl Hershner, director of the Center for Coastal Resources Management at VIMS and a member of the SAGE Leadership Team, says “The website includes more than 100 examples, to date, of ongoing or completed projects that incorporate SAGE principles. These projects incorporate restoration of green infrastructure such as dunes, oyster reefs, and wetlands. The variety of projects—from developing an 80-foot living shoreline to installing 3 acres of tidal wetlands—demonstrates the many ways communities can incorporate SAGE into their planning.”

The partnership has also developed a brief primer, “Natural and Structural Measures for Shoreline Stabilization,” that aims to help the public better understand both the threats to their coastal communities and the techniques that can be used to mitigate those dangers.

VIMS scientist Pam Mason, a member of the SAGE management team, says the primer “uses plain language and lots of graphics to depict various approaches to both green and gray infrastructure.” She adds that it “not only shows the benefits and disadvantages of 10 different green and gray infrastructure approaches, but also provides some design and cost information for each.”

The SAGE alliance is a community of practice and not a grant-making or governmental organization. It provides a forum to leverage resources for coastal projects that incorporate hybrid coastal engineering. Partner organizations have committed to in-kind support to develop and support the effort.
