1. Q AVG US Army Corps of Engineers BUILDING STRONG ® Q AVG US Army Corps of Engineers BUILDING STRONG ® USACE Regional Sediment Management Program Linda S. Lillycrop US Army Engineer Research and Development Center (ERDC) West Maui RSM Workshop 27 August 2014 Kihei, HI

2. Why Regional Sediment Management?

3. Regional Sediment Management A systems approach for efficient and effective use of sediments and management of projects in our Coastal, Estuarine, and Riverine environments

4. RSM = Sustainable Solutions for….. Navigation/ Dredging Flood Risk Management Environmental Restoration RSM Operating Principles  Recognize sediment as a regional resource  Balanced, economically viable, environmentally sustainable solutions  Improve economic performance by linking multiple projects  Optimize operational efficiencies & natural exchange of sediments  Consider local & regional impacts (physical, environmental, social )  Apply/develop technology & tools to optimize system  Share information & data, reduce data duplication  Coordinate/Collaborate/Leverage with stakeholders & partners

5. RSM Team USACE Stakeholders and Partners Identify Opportunities and Solutions Decision Making Take Action Share Successes and Lessons Learned Overcome Obstacles Leveraging Resources, Data, Tools, etc

6. 25 Districts, R&D Historical RSM Participation (2000-2014)

7. Case Studies 7/30

8. Perdido Pass, Alabama Optimize Sand Bypassing Pre-RSM Post-RSM Shoaling Area Placement Area 0.5-1.5 mi

9. Mouth of the Columbia River, OR Collaboration 2002: District & Stakeholders - Leverage: Projects, Resources, Models, Tools, Data Collection… - Long-term strategy - Construction 2012 - Monitoring 2013-2014 Benefits - 4 New nearshore BU sites - Reduced dredging costs - Stabilize Inlet morphology - Protect navigation structures - Reduce shoreline erosion - Environmental habitat 1939 Benson Beach * * head of jetty in 2002 2002 North Jetty *

10. Jacksonville District St. Johns Co. RSM  Intracoastal Waterway (IWW)  San Sebastian River  St. Augustine Inlet  St. Augustine Beach SPP  Vilano Beach (Feasibility Study)  Anastasia State Park Benefits Combined O&M SPP projects $5-7 million savings dredge (mob/demob) Lower risk of environmental impact with less dredging, Combining permits, Back-up sources for emergency nourishments

11. Mobile District: Mobile Bay Basin RSM Reduce sedimentation/optimize disposal Stakeholder PDT  Alabama Department of Conservation and Natural (ADCNR), State Lands Division  ADCNR, Marine Resources Division  Alabama Department of Environmental Management (ADEM)  Alabama State Port Authority  U.S. Fish and Wildlife Service  NOAA, National Marine Fisheries Service  Alabama/Mississippi Sea Grant  Mobile Bay National Estuarine Program

12. 1000-acre habitat in upper bay Restore wetlands that have been lost in bay Place 2M/every 2-yrs = 9-10 Mcy Upper-Bay In-Bay Disposal Thin-Layer Disposal Lower Bay: ODMDS Mobile District: Mobile Bay In-Bay Disposal Strategy RSM and Engineering With Nature ODMDS

13. RSM Summary  Manage local projects in Regional Context  Understand local/regional processes, sediment sources & sinks  Enhance & Share data, tools, technology, and lessons learned  Seek solutions which maximize use of sediment/minimize costs  Collaboration/communication with stakeholders and partners ► Identify Opportunities, Decision Making, Coordinate and Implement Actions  Take Action: Construct
