Coastal Resilience: Status Quo is Grey http://www.garlandconsultancy.com/our- projects/infrastructure/costal- protection- works.html
McCreless & Beck, 2016. http://blog.nature.org/science/2015/09/08/coastal- infrastructure- is- it- time- to- update- our- investment- portfolio/ Coastal Resilience Funding: Mostly Grey Shift 10% of risk reduction and recovery spending towards habitat restoration & conservation
Coastal Resilience Through Green and Grey Monmouth County, New Jersey Vital 5 m seawall damaged during H. Sandy $34 M for repairs, 90% via FEMA ~0.5 mile of new seawall
Coastal Resilience Through Green and Grey ~350 Ha protected wetland Avoided US$ 7.9 M (~5%) damages during H. Sandy Army Corps: Large- scale engineered protection needed for properties built on previous marsh Monmouth County, New Jersey Vital 5 m seawall damaged during H. Sandy $34 M for repairs, 90% via FEMA ~0.5 mile of new seawall
Coastal Resilience: Assessing Green like Grey Change in Property Damages During Hurricane Sandy due to Wetlands Ø 625 Million US$ Ø 12 States Ø 15% annual savings Difference in Losses (%) <-60-60 to - 50-50 to -25-25 to -10-10 to -5-5 to -0.5-0.5 to 0.5 0.5 to 5 5 to 10 10 to 25 25 to 50 50 to 100 >100

Financing Natural Infrastructure for Coastal Resilience
Financing Natural Infrastructure for Coastal Resilience: Framework + + +
Financing Natural Infrastructure: Opportunities
Financing Natural Infrastructure: Opportunities Reef Resilience and Insurance Fund Quintana Roo, Mexico First example of insuring natural resource for resilience benefits work in- progress Relies on rigorous engineering- type assessments of benefits Local partnership between private property owners and public agencies is key
Financing Natural Infrastructure: Opportunities Eelgrass and Oyster Reef Restoration San Rafael Shoreline, San Francisco Bay Multiple objectives including erosion control and habitat enhancement Pilot study to understand and learn restoration processes and benefits Partnership between State Coastal Conservancy, The Nature Conservancy, others
Natural Infrastructure for Coastal Resilience Unlocking Funding Resources 1. Assess Green like Grey unlock existing resources and develop new mechanisms 2. Recognize how Green is distinct from Grey Partnerships Multiple benefits 3. Implement and Learn! Body of practice and model examples
