Living Shoreline Sea Level Resiliency: Performance and Adaptive Management of Existing Breakwater Sites, Year 2 Summary Report
Virginia Institute of Marine Science
The Coastal Zone Management program, through NOAA grants, has funded several projects that have reviewed design considerations and monitored living shoreline systems for effectiveness at both shore protection and habitat enhancement. These studies presented data regarding the construction and performance of three living shoreline projects that were built between 1999 and 2003 in Maryland (Hardaway et al., 2007 and 2009) and were in part the basis for the “Living Shoreline Design Guidelines for Shore Protection in Virginia’s Estuarine Environments” and the contractor training classes (Hardaway et al., 2017). In addition, extensive research has been done on the design and performance of breakwater systems around Chesapeake Bay (Hardaway & Gunn, 1991; 2010; 2011). Breakwater and beach systems are appropriate for medium to high energy shorelines along Chesapeake Bay and its tributaries. ....
The present project seeks to build upon and expand monitoring efforts of sills and headland breakwater systems in Chesapeake Bay to determine effectiveness of shore protection and habitat creation and stability through time using a detailed site assessment and survey of five sites (Figure 1-1) including Aquia Landing, Bavon, Kingsmill, Virginia Institute of Marine Science (VIMS), and Yorktown. In addition, referencing the latest research results of migration and accretion of beaches and marshes in Chesapeake Bay, the project will seek to determine what elements make these successful over the short and longer terms.
