Project PurposeTo provide science-based information about
the best shoreline management options forpreserving important natural functions ofthe Hudson River Estuary’s shore zone,
NYS Department of Environmental Conservation
especially as sea level rise acceleratesand storms increase in intensity.

– Detailed ecological analyses
NYS Department of Environmental Conservation
– In-depth studies of ice, currents, and wakes – Demonstration project – Tools for decision-makers
Five Big Objectives A. Characterize estuary & shoreline conditionsB. Determine ecological, engineering & economic
trade-offs of management options
C. Characterize decision-making arenas &
NYS Department of Environmental Conservation
opportunitiesD. Demonstrate innovative shorelines & BMPsE. Create decision tools & communicate results
A. Characterize Present andFuture Conditions
• Sea level rise and flooding projections• Scenarios of future conditions
•
NYS Department of Environmental Conservation
• Detailed assessment of physical forces
on shorelines*• Shorelines GIS
*1-day workshop on current modeling

B. Determine Ecological,Engineering & Economic Tradeoffs• Ecological Tradeoffs
– Literature review – Ecological comparison of natural &
NYS Department of Environmental Conservation
engineered shorelines – Related shorelines research – In-depth study of ecology of engineered
shorelines
Field studies for 2011• Focus on built shorelines
• Study biodiversity (fish, plants) andorganic matter accumulation as afunction of shore zone structure & age
NYS Department of Environmental Conservation
• Test rapid assessment protocols• Manipulate wrack
B. Determine Ecological,Engineering & Economic Tradeoffs• Engineering Tradeoffs
– Soft shoreline alternatives analysis – Literature review
NYS Department of Environmental Conservation
– Analysis of 6-10 stabilization techniques
B. Determine Ecological,Engineering & Economic Tradeoffs• Economic Tradeoffs
– Literature survey/assessment of how bestto estimate and compare costs of
NYS Department of Environmental Conservation
alternative shoreline stabilizationapproaches*(Construction costs, maintenance costs,ecosystem services values, other?)
* 1-day workshop being planned
NYS Department of Environmental Conservation
B. Determine Ecological,Engineering, Economic, and Social
and Cultural Tradeoffs
• Social & Cultural Tradeoffs – Community preferences about shoreline types
NYS Department of Environmental Conservation
– Other studies or analyses?

C. Characterize ShorelineDecision-Making Arenas
and Opportunities• Focus groups• Anal sis of en ineers and other ex erts
NYS Department of Environmental Conservation
• Shoreline case studies• Legal and regulatory review
D. Demonstrate InnovativeShorelines & Best
Management Practices• Demonstration site design and
NYS Department of Environmental Conservation
construction• Network of demonstration sites*
• *1-day workshop being planned
•
Shoreline Demonstration Projects: A Par tnership Approach
• SS Project Team will provide support to incorporate“soft” or “ecologically enhanced” elements into shorelineproject designs.
NYS Department of Environmental Conservation
• Network of partnership projects will include a variety of: – Settings (developed/natural, physical and chemical environment) – Priorities and constraints (protection of natural resources,
property, infrastructure and uses) – Solutions (bioengineered, addition of habitat enhancements)

E. Create Shoreline DecisionTools & Communicate Results
• Outreach and engagement plan• Summary of stakeholder input
NYS Department of Environmental Conservation
• User-friendly “key findings” documents• Decision tools• Training
NYS Department of Environmental Conservation
Future Decision Tools
• Probably GIS map-based• Will provide more localized info about
NYS Department of Environmental Conservation
• Might incorporate rapid assessment
approaches (ecological, physicalstresses) to identify best alternatives
• Accessible on the web?
Questions
• Do you see gaps or redundancies?• Are there linkages that need to be
made?
NYS Department of Environmental Conservation
• Do the emerging reports & productsseem useful?
• What do you think of the overview?
