Several examples of regional proactive planning already exist for shorelines: the USACE Regional Sediment Management approach, the USEPA National Estuary Program, and some special area management plans approved by state coastal management programs. Some aspects of all these experiences offer guidance for proactive regional planning for shoreline erosion control.

Development of a shared vision will also incorporate the views of local property owners and users of the shoreline. In the absence of a vision to describe the desired shoreline, the future of sheltered shorelines will be decided through individual permitting decisions that may not reflect the values of the affected communities.

. Defining the Region There are many ways to define the scope of the region of shoreline management plans.

These summary documents would need to be routinely updated to reflect knowledge gained from monitoring and research activities for revisions of regional plans. Monitoring Requirements Erosion mitigation measures typically affect aquatic resources, landforms, property values, private or public infrastructure, regional sediment supplies, critical habitats on private properties, public property, or on property held in public trust.

FINDING: The current regulatory framework for sheltered coasts contains disincentives to the development and implementation of erosion control measures that preserve more of the natural features of shorelines, mainly as a result of the combined lack of knowledge, vision, and planning. The existing system presents two main obstacles: • Obstacle 1: General lack of knowledge and experience among decisionmakers regarding alternative options for shoreline erosion response, the relative level of erosion mitigation afforded by the alternative approaches and their expected life time, and the nature of the associated impacts and benefits.

• Long-term shoreline erosion information should be gathered and included in publicly available maps, such as flood insurance rate maps, to more accurately reflect the risks and potential costs of building on erosionprone shorelines. These maps would provide better information for property buyers and insurers and could guide localities in establishing land use and zoning policies.

Topics for studies: -- Identify trade-offs in ecosystem services associated with various mitigation measures, -- Quantify the costs and benefits of nonstructural erosion control techniques, -- Document system-wide process and hazard information, includ ing mapping of erosion zones and rates. This information needs to be presented in nontechnical formats such as summary maps that can be readily understood by decision-makers, and -- Develop models to predict the evolution of coastal features under various scenarios.

• The national dialogue should be used to develop guidelines for mitigating erosion on sheltered coasts that give deference to ecologically beneficial measures and ensure consistency of decision-making across regions. • The national dialogue will require development of handbooks or Web pages with objective information about erosion mitigation techniques, including descriptions of the conditions under which each option would be effective.

RECOMMENDATIONS: • The decision-making process should account for ecosystem services when permitting coastal shoreline stabilization projects. Decision-makers

RECOMMENDATIONS: • The development of regional shoreline management plans for sheltered coasts should occur at the state and local level in partnership with the federal government. Plans should be proactive and comprehensive in scope, and should be scaled to the estuary, bay, or littoral cell as appropriate.
