This document summarizes a presentation by Dale Morris on resilience strategies for coastal areas vulnerable to sea level rise and extreme weather. Some key points: - Nearly half the world's population lives in coastal areas that are increasingly at risk. - Extreme weather events are causing more damage as populations and wealth in coastal areas grow. Recent hurricanes and floods have resulted in hundreds of billions in losses. - The Netherlands addresses its flood risk through extensive planning, multi-purpose projects, and "living with water" strategies like beach and dune nourishment, sea dikes, water squares, and coastal marsh restoration. - Hampton Roads could benefit from a regional resilience plan, a lead state agency, and funding to implement projects that

2. Rising Seas: Vulnerability and Occurrence
Population
•In 2010, 44% of world population lived in coastal areas (UN).
• 65% world GDP in coastal areas
•In 2010, 123 million -- 39% of US population -- live in coastal counties. Between 1970 to 2010,
the population in these counties increased 40%, and an additional 8% (10m) by 2020 (NOAA).
• 45% US GDP in coastal counties

Extreme weather: “We all pay, one way or another.”
Since 1980, $1 billion disasters in the U.S. have
tripled. More people, wealth, capital in coastal areas.
…from 1980 to 2011, weather-related catastrophes
cost…an average of more than $34 billion a year.
Losses…are rising in a long-term trend consistent with
models of climate change.
Katrina $150 b, Sandy $60 b, Ike $40 b,
Isaac $2.9 b, Matthew $ 10 b
Houston Tax Day 2016 $1.2 - $1.9 b

…and SLR will exacerbate impacts in coastal areas

5. Water Mgmt and SLR in NL
59% of land is at or below sea level
70% of people live in, and 70% of GDP is
produced in, flood-prone areas
Adaptation easier: public will, and past flood
investments help w/ challenge
IPCC SLR mid-level projections:
--8 inches by 2050
--33 inches by 2100

About the Dutch Dialogues (DDs)
DDs are a process to assess and plan for current and future risks: climate, social, economic, water.
DD teams are multi-discipline, cross-cultural: 1 + 1 = 3. Silos forbidden…
Extensive preparation (data, viewpoints, visions, programs, local willingness) to assess if a DD team can
make a difference.
Jointly discover: facts, possibilities, methods, and multiple-benefit solutions, and share those with
political leaders.
DDs main goals are to aggregate the expertise of multiple disciplines, scales and stakeholders to
problem-solve actionable challenges.
Dutch saying: “First, we have to get all noses pointed in the same direction.” Set forth a roadmap and
“vibe” for ongoing action.
DDs in New Orleans, St Louis, Los Angeles, Miami, Tidewater.

National Gov’t preferred option:
--straigten the (red) line of protection
--coastal dune heightening (+10 - + 12 ft)
--beach widening
--sand is primary tool
Local Gov’t had concerns:
--beachfront views, and access, for
Homeowners, tourists and retail
--”separation” of town and sea
--redevelopment
--land value

spaces. Better beach access. Better beachfront retail.

48. Closing thoughts
• Urban drainage is undersized for extreme precipitation and SLR-induced drainage constraints. Uncertainty
over duration of future weather events and future rate of SLR requires robust and multipurpose investments.
• Green infrastructure works well to reduce risk in many places, and provides ancillary ecosystem services and
economic benefits.
• Suppliers supply least-costly solutions, are not incentivized to think outside the box. (Exact opposite of Dutch
approach).
• Procuring agencies straightjacketed, policy / regulatory conflicts and silos (Fed-Fed, Fed-state) impair
implementation. No one dares to excel.
• Liability worries make multi-purpose/multi-goal projects improbable. Do we need the dual mandate -- eg
Safety and Spatial Quality -- in the law / authorizations (like the Dutch)?
• Hampton Roads needs the legal authority to regionally plan and coordinate SLR actions.
• VA State Gov’t should empower one state agency to lead state-level SLR activities and coordinate/streamline
state-level adaptation efforts. “Until someone is in charge, no one is in charge.”
• Funding. Pay me now or pay me later…
