SOUTHEAST COASTAL ASSESSMENT: Creating a shared vision

Transcription

1 SOUTHEAST COASTAL ASSESSMENT: Creating a shared vision November 12, 2017 Jacqueline Keiser, PG, PMP Regional Sediment Management Regional Center of Expertise SOUTH ATLANTIC DIVISION U.S. ARMY CORPS OF ENGINEERS Jacksonville District

2 2 Presentation Purpose: To discuss the need, value, and path forward towards an understanding of the coastal vulnerabilities in the southeast United States and a shared vision in addressing those vulnerabilities.

9 South Atlantic Coastal Study: AHEAD OF THE STORM WIIN 2016 SEC SOUTH ATLANTIC COASTAL STUDY. (a) IN GENERAL. The Secretary shall conduct a study of the coastal areas located within the geographical boundaries of the South Atlantic Division of the Corps of Engineers to identify the risks and vulnerabilities of those areas to increased hurricane and storm damage as a result of sea level rise No discussion of cost share Expanded area with 4-year timeframe Implementation guidance has not been finalized PMP drafted but will need to be updated Stakeholders support high but sponsorship a challenge Leverage NACCS lessons learned Provide consistent picture of vulnerability Provide focus to future efforts/projects 9

10 WHAT CAN WE DO WITH WHAT WE HAVE? =Southeast Coastal Assessment (SCA) INNOVATION THROUGH IMPROVED COORDINATION OF AUTHORITIES, PROGRAMS, ACTIONS and LESSONS LEARNED LEVERAGING

11 Southeast Coastal Assessment (SCA) SERVES AS A FOUNDATION FOR FUTURE solutions SCA Tier 1 Establish Southeast Coastal Coalition ASBPA and CSO collaborating to build coalition Consistent, regional assessment of coastal vulnerability with existing data Will not include specific measures, NEPA, or recommendations outside of current authorities SACS Tier 2 Seamless focused transition from SCA Identify, evaluate, compare solutions Provide useable tools to stakeholders Solutions Implemented Tier 3 11

12 12 COALITION DEVELOPMENT: Priority #1 WHAT: Engaging stakeholders, understanding needs, leveraging existing efforts and expertise WHO: States, Agencies, DOD, Non-governmental Organizations (NGOs), Academia, tribes, Industry, HOW: Collaborative effort between ASBPA, CSO, and USACE. WHEN: Immediately. Conference outreach followed by kick off webinars November meeting with States/Governors - December Federal agency engagement - Jan/Feb Regional stakeholder engagements WHY?: So that the interdependent problems of coastal vulnerability can be understood jointly and addressed cooperatively. The Coalition will ultimately help drive the scope for SACS. Coalition building under SCA will influence SCA outputs to some degree but is largely intended and critical to inform and direct the scope and outputs of the deeper dive Tier 2 (SACS) efforts.

13 13 TECHNICAL APPROACH RISK = EXPOSURE X PROBABILITY OF HAZARD UTILIZE INTEGRATED PRODUCTS FIRST USACE, federal and academic Integrated Products which incorporate physical, economic and cultural data and process models to inform decision-making. NSMS Shoreline Change & its Economic & Environmental Implications; Seeks Collaborative Solutions SAGE Advancing the Practice of Natural Infrastructure & Resilience USACE SLC Calculator Sea-level Change Projections (Uses NOAA Long-term Tide Gauges) NOAA SLR Viewer Spatial Extent of Areas Potentially Affected by Sea Level Rise USGS COASTAL VULNERABILITY Erosion Due to Storms (storm surge, elevation, wave set-up & run-up) FEMA FIS/NFHL Flood Hazard Mapping Drill down to find Data Gaps

14 SCA Risk Areas Identification SCA Risk Areas Identification Identification of geographic regions (tract level) at risk as a function of the Composite Exposure Index and flood probability scenarios (hazards) Products: GIS Platform and data sharing is key * Report/website Coalition with established Charter Actions immediately implementable Focus of future study needs RISK = Exposure X Probability of Hazard
