Hudson River Sustainable Shorelines

Advisory Commi ttee

May 6, 2011Norrie Point

NYS Department of Environmental Conservation

Project PurposeTo provide science-based information about

the best shoreline management options forpreserving important natural functions ofthe Hudson River Estuary’s shore zone,


especially as sea level rise acceleratesand storms increase in intensity.

Approach

• Interdisciplinary : integrate many

research approaches• Collaborative : involve partners doing


• Facilitated : work with professionals to

facilitate research and stakeholderengagement

Project Team• DEC Hudson River

Research Reserve• HR Estuary Program• Cary Institute of

Ecosystem Studies

• The Nature Conservancy• Scenic Hudson• NYS Energy Research

Development Authority• DOS Coastal Program


• Stevens Institute ofTechnology

• Consensus BuildingInstitute

• Thrive Consulting• Pace Land Use Law

Center

• NYS Office of Climate Change• New York Sea Grant• Cornell University• HRV Greenway

Principal Funding• CICEET: 2008-2012• NERRS Science Collaborative: 2010-2014

– Detailed ecological analyses


– 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 &


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

•


• 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 &


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


• Test rapid assessment protocols• Manipulate wrack

B. Determine Ecological,Engineering & Economic Tradeoffs• Engineering Tradeoffs

– Soft shoreline alternatives analysis – Literature review


– 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


alternative shoreline stabilizationapproaches*(Construction costs, maintenance costs,ecosystem services values, other?)

* 1-day workshop being planned


B. Determine Ecological,Engineering, Economic, and Social

and Cultural Tradeoffs

• Social & Cultural Tradeoffs – Community preferences about shoreline types


– Other studies or analyses?



C. Characterize ShorelineDecision-Making Arenas

and Opportunities• Focus groups• Anal sis of en ineers and other ex erts


• Shoreline case studies• Legal and regulatory review

D. Demonstrate InnovativeShorelines & Best

Management Practices• Demonstration site design and


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.


• 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)

Potential SiteLocations


Coxsackie Boat Launch, Greene County


Eroding Shoreline




E. Create Shoreline DecisionTools & Communicate Results

• Outreach and engagement plan• Summary of stakeholder input


• User-friendly “key findings” documents• Decision tools• Training


Future Decision Tools

• Probably GIS map-based• Will provide more localized info about


• 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?


• Do the emerging reports & productsseem useful?

• What do you think of the overview?
