Virginia CZM Program LogoEffects of Waterfront Development on Virginia's Shorelines

Waterfront development, often for retirement or summer homes, is an ever more common sight along the creeks and rivers of Virginia’s coastal zone. Waterfront property is expensive, so one of the first “improvements” new property-owners typically consider is stabilizing their shoreline in order to prevent erosion and protect their investment.

Although a number of options are available for managing shoreline erosion, many landowners choose to harden their shoreline with either a riprap revetment (rock) or a wood or vinyl bulkhead, also known as 'seawalls'. Building these structures along the shoreline may require removing vegetation in order to gain access for construction activities. Depending on the height and condition of the shoreline bank, some property owners also grade their property next to the shoreline to reduce the slope to the water and prevent bank erosion.

Unfortunately, some shoreline stabilization practices can have detrimental effects on coastal resources:

  • Impacts to important habitats and to water quality can occur because of the loss of trees and shrubs, wetlands, beaches, banks, and underwater grass beds.  Some of these losses occur immediately because of shoreline structure construction, access to shoreline areas for machinery, or grading. Others are more gradual and may result from scouring and sediment resuspension from reflected wave energy or the inability of fringe marshes and beaches to migrate landward as sea level rises. Shoreline stabilization can also affect the gradual movement of sediment along the shore and cause increased erosion on nearby properties.
  • Removal of shoreline vegetation can cause shallow water temperatures to rise. This can adversely affect fish. Loss of trees and shrubs also reduces food and cover for birds and other wildlife.

What is the Virginia CZM Program doing to address this issue?

The Virginia Coastal Zone Management (CZM) Program completed assessments of coastal resources in 2006 and 2011 as well as a planning initiativesto direct efforts through a number of specific strategies, funded under Section 309 of the federal Coastal Zone Management Act.  Visit the Coastal Needs Assessment and Strategies web page for more information.

Shoreline Management Strategy

One of these strategies targeted shoreline management.  The Shoreline Management Strategies focused on promoting living shorelines (see side bar)

Over a ten-year period this strategyprovided $1,538,019 for various initiatives and produced the following outcomes.  

  • A 'Living Shoreline Summit' with peer reviewed proceedings, to advance the use of this management technique (held December, 2006)
  • Revised 'Wetlands Guidelines' to be used by the Virginia Marine Resources Commission, the Virginia Institute of Marine Science, local wetlands boards and others to guide decisions about shoreline and tidal wetlands management.
  • Improved data on shoreline conditions to support more informed shoreline management decisions.
  • Research to document the habitat value and viability of living shorelines and to improve their design.
  • Guidance for local governments to use in shoreline management planning.
  • Outreach materials for land use decision-makers, landowners and contractors on living shoreline advantages and design principles.
  • A training program for contractors and local government staff on living shoreline practices.
  • A report on improving management of Virginia's dune and beach resources, including proposed revisions to the Coastal Primary Sand Dunes and Beaches Act. 
  • Changes to the Coastal Primary Sand Dunes and Beaches Act by the Virginia General Assembly (Adopted 2008 – expanded Act from 9 localities to the entire coastal zone)
  • Revisions to the Coastal Primary Sand Dunes and Beaches Guidelines.
  • A comparative analysis of two methodologies for developing local shoreline management plans.

Living Shorelines Initiative

Living Shorelines are restored shorelines that, in addition to protecting property from erosion, provide habitat for fish, birds and other wildlife.  Like undisturbed natural shorelines, they also protect water quality by trapping excess nutrients and sediment.  Photo by K. Duhring, VIMS.

While revetments and bulkheads and other methods that 'harden' the shoreline provide property owners with erosion protection, they degrade the ability of the shoreline to provide habitat for aquatic life and to filter storm water runoff. Many low energy shorelines are being hardened where less damaging techniques for managing shoreline erosion could be employed.

The Virginia CZM Program Office has working with the program's partners to promote Living Shorelines, a technique that not only stabilizes the shoreline but provides valuable habitat and improves water quality.

Living Shorelines are shorelines that have been altered by man to protect them from erosion and to create habitat using nature-based techniques such as marsh plantings, beach nurishment, and low profile oyster reefs, breakwaters and sills.

Shoreline Technical Assistance Toolbox - NOAA Office for Coastal Management --- The Shoreline Technical Assistance Toolbox provides coastal resource managers with centralized access to information, resources, and tools to address shoreline erosion and management, focusing on alternatives to traditional shoreline hardening. The Toolbox includes information on planning and policy tools, alternative stabilization techniques such as “soft” or hybrid methods (e.g. marsh restoration with breakwater sill), and the economics of shoreline management. For each technique, the site also provides case studies describing how each technique has been applied. In addition, the Toolbox also includes a “resources” page that provides links to a variety websites, reports and management tools related to shoreline management.
