EXECUTIVE SUMMARY

This paper uses engineering management concepts to address adaptation strategy activities

in response to regional sea level rise (SLR) in Southeastern Virginia. In particular, Norfolk is

encountering the complex challenges incident to climate change: rising seas and tides, more

extensive flooding, increasing frequency and intensity of adverse weather and accelerated

shoreline erosion. The impacts are far-reaching across the city and trends show that the

problem is getting worse. Engineering management concepts such as knowledge

management, systems analysis, engineering design, project management, environmental

planning and stakeholder consensus are useful when confronting “wicked” problems such as

this. The nature of the adaptation strategy is formulated using a systems-based perspective,

which is the foundation for the methodology. The strategy must be rigorous enough to help

authorities, businesses, property owners, and community planners in Norfolk cope with the

dynamic changes, higher uncertainty, and growing complexity due to SLR-based inundation

and erosion. The methodology is applied to a high-risk property in Norfolk, which serves as

a “roadmap” for prospective planners. Finally, the paper concludes with implications,

evaluates the project using objective assessment criteria, and recommends a way ahead for

taking on SLR-related issues both at the local and regional levels.

INTRODUCTION

Background: Authorities, land owners, businesses, and community planners in

Tidewater Virginia are being challenged by the negative effects of rising sea levels. This

inevitable phenomenon will force regional property owners to either adapt to or abandon

rapidly growing flood zones in the local communities. Former Old Dominion University

(ODU) president James Koch, in his annual State of the Region report, called sea-level

rise “the problem of the 21st century for Hampton Roads.” His assertion applies

specifically to Norfolk, which has experienced the highest relative increase in sea level

on the Eastern seaboard (14.5 inches since 1930). Rising sea levels have made the

region more vulnerable to storms, flooding, and tidal surges. Only New Orleans and

Corpus Christi are worse (Koch, 2010; McFarlane and Walberg, 2011).

The impacts of the changing climate are nowhere more imminent or intense than in

the coastal zones. Rising global temperatures, thermal water expansion, and land base

subsidence are all contributing to the following: sea level rise (SLR), altered precipitation

patterns, more frequent adverse weather effects, accelerated coastal erosion, increased

coastal water sedimentation, further saltwater intrusion of ground water, greater potential

for pollution from runoff and destroyed infrastructure. Paradoxically, reckoning with SLR is

easily postponed because it is not perceived as an immediate management concern. Yet

it cannot be ignored because of its potential for long-term, irreversible impacts on coastal

land use, populations, economies, and ecologies (Moser, 2005). Adaptation strategies

using engineering management concepts must be developed and applied to help Norfolk

residents confront these issues.

Page 7: Applying Engineering Management Concepts to Sea Level Rise

Context and Terminology: Methods for Managing SLR

Nicholls et al. (2008) discusses that SLR effects can have direct and indirect socio-

economic impacts depending upon human exposure to these changes. The coastal

system can be defined in terms of interacting natural and socio-economic systems. Both

systems are dynamic and complex, but adjustment can be distinguished in two forms:

autonomous and planned adaptation. Autonomous adaptation represents the natural

adaptive response to SLR such as increased vertical accretion of coastal wetlands within

the natural system. Bay tidal wetlands can help reduce future coastal flooding impacts

from SLR and may be permanently inundated or eroded as a result of SLR unless (1)

adequate amounts of sediments and/or production of organic matter allow marsh

elevations to rise at the same pace of SLR and/or (2) the wetlands are able to migrate

inland as the water levels rise (Culver et al., 2009). Autonomous adaptation is often

lessened or may be halted by human-induced, non-climatic influences.

On the other hand, planned adaptation, which emerges from socio-economic

systems, can reduce SLR-based vulnerabilities by a range of different methods. Ideally,

there are three (3) generic approaches (Volk, 2011):

Protection is the approach in which natural systems are controlled by hard or soft

engineering thereby reducing human influences in the zones that would be impacted

without the protection.

Managed Retreat employs the method in which all natural systems are allowed to

occur and human impacts are marginalized by “withdrawing” from the coast.

Accommodation is another approach where all natural systems effects are permitted

to occur and impacts are minimized by adjusting human use of the coastal zones.

Page 8: Applying Engineering Management Concepts to Sea Level Rise

3

These approaches can be then discretely categorized further into several different

planned adaptive methods to address SLR and coastal flooding as follows (Tam, 2009):

Barrier: a dam, gate, or lock or series of them managing tidal flows/ebbs.

Coastal armoring: linear shoreline protection in the form of seawalls or levees.

Elevated development: raising the height of the land and/or existing development.

Floating development: structures that either float permanently or are floatable in the

event of flooding. This concept is often referred to as “aquatecture.”

Floodable development: structures designed to withstand flooding or retain water.

Managed retreat: planned abandonment of threatened areas near the shoreline.

Living Shoreline: use of natural means (i.e., marshes/wetlands) to absorb

floodwaters, inhibit erosion, and provide habitat.

The advantages and disadvantages of the above methods are provided in Table 1.

Table 1: Advantages and Disadvantages of Methods for Managing SLR

Method Advantages Disadvantages

Barrier - Protects large areas from flooding - Can regulate flow & water level

- Expensive to construct - Ecologically damaging

Coastal Armoring

- Fixes shoreline in place - Good storm surge protection - Protects high value properties or threatened habitats

- Requires periodic maintenance - “Re-engineering” may be needed to accommodate storm surge and rising baseline sea levels

Elevated Development

- Enables flood-prone area building - Can retrofit low-lying infrastructure

- Alters shoreline characteristics - May require erosion protection

Floating Development

- Manages tide/flooding uncertainty - Resilient to seismic activity

- Not feasible for high-energy shorelines (high wind & waves)

Floodable Development

- Suite of tools selectable to the site - Better suited for urban areas

- Relatively untested concept - Damage beyond design volume

Page 9: Applying Engineering Management Concepts to Sea Level Rise

Managed Retreat

- Minimizes infrastructure damage through planned relocation - Enhances natural restoration

- Expensive to relocate heavily developed areas - Complex legal and equity issues

Living Shoreline

- Naturally adaptive to flooding - Creates critical natural habitat

- Needs greater land management - Requires time & monitoring

Issue Importance: As discussed, Norfolk is being challenged by a host of complex SLR-

induced issues. The mitigation methods ought to be developed on a strategic level

(region or community) so that they can be better applied at a tactical level (individual

neighborhoods and property owners). The methods discussed above as planned

adaptation strategies are neither an exhaustive nor extensive range of options. There will

be both benefits and drawbacks with each strategy, and a “one-size-fits-all” solution does

not exist. Some of these strategies may even be combined together. The implementation

of these strategies must be a collaborative approach seeking to enhance stakeholder

knowledge and build relationships.

The most significant shortfall facing Norfolk residents is the absence of a “go-to”

centralized authority and comprehensive plan regarding SLR issues, which results in

formulation of individual mitigation efforts that do not support an overarching plan. City

environmental planners are advocating the use of “living shoreline” treatment for erosion

control, but it is not part of a written policy or overall planned adaptation strategy. This

paper discusses a specific application of this treatment using a high-risk property in

Norfolk’s Larchmont section. This example ought to influence other local property owners

to consider a SLR management approach using a “living shoreline” treatment, which

provides good erosion control benefits while enhancing the natural local shoreline

Page 10: Applying Engineering Management Concepts to Sea Level Rise

habitats. Although the best SLR method for a specific case depends upon numerous

input factors, since most properties on Norfolk were built around tidal marshes and

wetlands, the assumption for employing this approach is very feasible.

There are a number of distinct issues which need to be addressed prior to

developing a methodology used as a countermeasure for the negative effects of SLR.

PROJECT DEFINITION

Purpose: The purpose of this paper is to use engineering management concepts to

address adaptation strategy activities in response to regional SLR in Norfolk, Virginia.

Engineering management concepts such as knowledge management, systems analysis,

engineering design, project management, environmental planning, and stakeholder

consensus are useful when confronting complex problems like this one.

Objectives: The following objectives are presented to support the project’s purpose:

Develop the methodology needed to address a complex system using systems

analysis.

Employ knowledge management to foster stakeholder consensus and analysis via a

participatory approach.

Use engineering design and environmental planning along with project management

for executing a “living shoreline” treatment project on a high-risk property in Norfolk.

Influence Norfolk property owners to consider this treatment as an environmentally

responsible and financially reasonable approach addressing the consequences of

SLR.

Emphasize the need for an overarching SLR adaptation strategy for Norfolk under the

auspices of a centralized responsible agency.

Page 11: Applying Engineering Management Concepts to Sea Level Rise

Evaluate project effectiveness using objective assessment criteria.

Project Focus and Significance: This project will focus on SLR adaptation strategies

for Norfolk, Virginia. The specifics involve analyzing the dynamic factors to assist regional

property owners and other stakeholders understand the issues, perspectives, and

irrationalities to help them make informed decisions. An iterative decision-making

process will produce plans in which resources are converted into systems meeting human

needs and solving problems. Project thinking is important for effective systems

organization to achieve complex problem resolution. There must be compatibility among

the problem, problem domain, expectations and resources (M5I: manpower, material,

money, methods, minutes, and information). A “first-pass yield” solution might not be

sufficient. The initial plan developed may require further data collection and processing,

negotiating, and problem solving.

The analytic strategy is the design for qualitative and quantitative exploration

required to understand and make decisions concerning this complex problem. It entails

strategy formulation, data qualification and gathering, data analysis methods, and data

interpretation. The project expectations include developing methods for decision-making,

interpretation, action, and assessment to support effective technical management. The

strategy ought to provide a basis for reframing the problem if required. The methodology

should then be tested to assess its effectiveness. Therefore, it is applied to a high-risk

property in Norfolk that can be used as a baseline for developing an overarching SLR

adaptive strategy at the local and regional levels.

The property used illustratively here has been subjected to the deteriorative

shoreline erosion resulting from rising sea levels and destructive effects of recent storms.

Page 12: Applying Engineering Management Concepts to Sea Level Rise

The combined effects resulted in the loss of about 145 ft2 of dry land property since April

2005. It is situated also on protected wetlands and is subjected to stringent environmental

regulations. The landowner will draft the needed paperwork (design and permits),

research and select required materials, perform needed manual labor, furnish all

monetary expenses, and provide lessons learned at local outreach programs.

PROBLEM FRAMING: level, scope, environment, goal, data set

There are a host of issues which must be identified, analyzed, and framed within the

proper context to develop the appropriate strategy. Engineering management concepts

such as systems analysis and knowledge management are useful in helping to properly

frame this complex problem. SLR and its coastal inundation effects in Tidewater Virginia

belong to a category of dilemmas called “wicked problems.” These are problems which

cannot be “solved” in and of themselves, but they can be properly managed within certain

bounds. Wicked problems are cross-disciplinary and are viewed from multiple

perspectives. Therefore, it is important to identify the critical elements and then gain

consensus on the problem situation to be addressed from as many stakeholders as

possible. Obtaining an acceptable answer to the correct problem is better than solving

the wrong problem precisely and committing a Type III error. A systems-based

methodology will provide an approach for the detailed examination of the operational

structure. Therefore, defining mechanisms are essential to defining system structure and

identifying “entering arguments” for framing this complex problem.

SLR-Induced Problems Facing Norfolk: Norfolk authorities, landowners, businesses,

and community planners have to reconcile actions for the following problems:

Page 13: Applying Engineering Management Concepts to Sea Level Rise

8

Problem #1: Climate change and SLR effects are inundating Virginia’s coastal zones

Problem Statement: Virginia has the highest rate of measured SLR of any state on the

eastern seaboard. An increase of 1.45 feet was registered by the Sewell’s Point tidal

gauge from 1909 to 2009 (NOAA Tidal Gauges, US Climate Change Program 2009); the

rate of sea level rise at the Chesapeake Bay Bridge Tunnel is 4.42 millimeters/year from

1927 to 2010 (Kilroy and Beatley, 2011, Ezer and Corlett, 2012).

Context: Relative sea level rise is being driven by two factors: absolute sea level rise and

land subsidence. The latter factor accounts for about one-third to one-half of the relative

SLR. As global average temperatures continue to increase, absolute sea levels will also

rise. By the year 2100, average temperatures are expected to rise by 5.1oF with annual

precipitation increasing by 11 percent. The aggregate result of these phenomena will

contribute to the existing SLR problem. Much of the East Coast of the United States can

expect to experience rises in sea level by about one meter by the turn of the next century

(McFarlane and Walberg, 2010; Hoyer, 2010) Moreover, the flat topography of Tidewater

Virginia could contribute to an average storm surge increase of about 3 feet over this

same time period (Harper, 2013).

Dynamics: Climate change is not only contributing to increasing coastal flooding but also

the frequency, intensity, and duration of adverse weather activity. Accelerated shoreline

erosion, loss of habitats (wetlands), saline intrusion of groundwater, and

property/infrastructure damage are the unintended consequences. The combined effects

of sediment compaction and groundwater withdrawal are causing the Tidewater Virginia

region to “sink,” which is resulting in the high disparity in relative SLR (Harper, 2010 and

Page 14: Applying Engineering Management Concepts to Sea Level Rise

9

Fears, 2012). For perspective, a one-meter SLR has the potential of inundating about 30

percent of the City of Norfolk (Brighton, 2012).

Perspectives: Scientists and academia have developed a myriad of theories regarding

climate change. Most of them agree that global warming is occurring as a result of

excessive greenhouse gas emissions due to human activity in burning carbon-based fuels.

Melting of polar icecaps and shifting Gulf Stream patterns are the key drivers for SLR on

the East Coast (Paskoff, 2006; Ezer and Corlett, 2012).

Problem #2: Regional economic and strategic activities are at risk

Problem System: Tidewater Virginia has significant economic and strategic assets and

activities being impacted by the increased flooding, accelerated shoreline erosion, and

more frequent storm surges and tidal actions.

Context: Tidewater Virginia was ranked as tenth in the world for assets at risk from SLR

(Nicholls et al., 2008). The region is home to numerous military and government

installations as well as other shoreline industrial sectors, such as marine terminals and

shipyards. In a nearby locality, the Virginia Beach waterfront has infrastructure which

supports the local economy through tourism. Many of the above activities are built on

low-lying ground, which are experiencing significant flooding and erosion problems.

Dynamics: The land recession threatens billions of dollars of oceanfront investments

focused just on tourism. SLR is already causing significant flooding issues in the older

shoreline communities, causing millions of dollars in adaptation efforts. Norfolk City alone

spends $6 million per year on flood mitigation and erosion control projects ranging from

overhauling storm drains, installing bulkheads in low-lying developments, and extending

Page 15: Applying Engineering Management Concepts to Sea Level Rise

10

outfall pipes in some of the waterfront residential areas (Hoyer, 2010). But the city’s

annual budget for addressing these issues is only $3 million (Hutchins, 2011).

Perspectives: The built environment in Tidewater Virginia has significant assets that are

vital to our local economy and national security. Both public and private infrastructure is

vulnerable, and adaptive strategies to protect these assets will cost time and money. A

comprehensive plan that does not include protection of certain high-risk zones will force

individual business and land owners to plan/fund/execute their own mitigation projects.

Problem #3: Wetlands, critical habitats, and natural systems are threatened

Problem System: Increasing inundation (levels and frequencies) is threatening the

natural systems in Southeastern Virginia.

Context: Higher tidal waters pose significant potential impacts to coastal ecosystems.

This includes loss of primary coastal dunes to erosion, loss of existing aquatic vegetation

(due to water clarity issues, rising water temperatures, and increased water depths) and

flooding of vegetative wetlands in intertidal zones (Pyke et al., 2008). These

environments support not only human systems, but also flora and fauna native to the

region as well as many migratory bird species. The wetlands are vital to the health of

Virginia’s ecosystems. They filter nutrients, sediment, and pollution from surface and

ground water, absorb excess flood and rain water, protect the shoreline from erosion, and

provide a habitat to native plants, animals, and birds (Brechwald, 2011).

Dynamics: Tidal wetlands can accrete vertically and have kept pace with past rates of

SLR. However, changes in sediment budgets, wetlands health, and accelerating SLR

can “overpower” this ability to accrete vertically. Due to SLR, the intertidal zones are

Page 16: Applying Engineering Management Concepts to Sea Level Rise

11

moving landward to their coastal ecosystems. The shoreward movement eventually

causes the wetlands to “drown in place” due to the presence of more hardened shoreline

infrastructures. Regional experts estimate that Virginia stands to lose about 50 to 80

percent of its tidal wetlands over the next century (Stiles, 2010).

Perspectives: Most of the infrastructure in Tidewater Virginia is built around tidal marshes

and wetlands. Regional environmental groups and city planners advocate the use of

“soft” structures such as living shorelines to preserve the existing wetlands and curb the

negative effects of increased seawater inundation.

Problem #4: Insurance premiums are increasing

Problem System: Nationwide, insurance premiums for home and business owners in

coastal communities have become more expensive and more difficult to obtain from

private insurance agencies. This condition is especially true in Tidewater Virginia.

Context: Devastating “megastorms” such as Hurricane Katrina have brought this issue

to the forefront. The most recent disaster, Hurricane Sandy, was one of the most costly

storms in American history and is still negatively impacting insurance agency profit

margins with some agencies reporting losses up to 77 percent during the last quarter of

2012 (Lubber, 2013). Risk modelers hired by insurance companies are updating their

schemata to include increasing SLR and water temperatures, both of which are resulting

in higher intensity storms and more frequent flooding activities (Shean, 2008).

Dynamics: The vulnerability of coastal properties and infrastructure to damage is

increasing as are the assets at-risk, while more high-risk development continues along

Virginia’s shorelines. Banks will not issue mortgages to new homeowners in high-risk

Page 17: Applying Engineering Management Concepts to Sea Level Rise

12

areas without flood insurance, which is becoming more difficult and expensive to obtain.

Insurance policy “blue-lining” is being implemented, in which some agencies will deny

new policies, reduce existing coverage, or cancel policies altogether. Other property

owners able to maintain coverage are faced with higher premiums and steeper

deductions (Smitherman, 2007). In Virginia, underwriting standards are not regulated so

the state has very little leverage to force private insurance companies to provide

coverage.

Perspectives: Insurance agencies, like other businesses, are seeking to maximize profits.

Since an excessive number of claims will impact profit margins, insurance firms are forced

to reconsider the number and types of policies based on risk analyses. In any case,

home, property, and business owners/renters will feel the impact either through lost

coverage or increased premiums/steeper deductions.

Problem #5: Lack of “centralized” authority and comprehensive plan

Problem System: There is no go-to authority for Norfolk (and Tidewater Virginia) business

and property owners to provide policy, guidance, and funding options for SLR adaptation

strategies.

Context: Communities and property owners at risk do not have a clear point of contact

for assistance from a central government agency. For example, if a property owner

desires to implement a SLR adaptation strategy to address an erosion control problem,

then the individual is forced to navigate and obtain compliance to a series of federal, state,

and local government requirements without a single, responsible point of contact.

Therefore, the individual projects are executed more in piecemeal, ad hoc fashion, which

is not normally part of an overall community adaptation strategy.

Page 18: Applying Engineering Management Concepts to Sea Level Rise

13

Dynamics: The implementation of a joint permit application (JPA) has streamlined the

process for individuals seeking approval for remediation projects. However, the JPA must

be presented and approved by federal (US Army Corps of Engineers), state (Department

of Environmental Quality), and local (City Planning) organizations. Since most of the built

environments are constructed around wetlands, the project must be briefed to and

approved by a local Wetlands Board. There are other entities that are added and

subtracted from the review, recommendation, and/or approval chain depending upon the

specific application. Nevertheless, the process is cumbersome and time-consuming.

Complex Systems Problem Perspective: Why is this scenario complex?

This situation is a complex problem because of the following dynamics:

This is a “wicked problem” with a large number of agents (stakeholders).

The relationship among stakeholders is complicated and interdependent.

SLR and shoreline inundation has economic, ecological, and strategic impacts.

Both human and natural systems will continue to be affected by higher tidal flows.

Insurance coverage in the region is increasingly difficult to secure and existing policy

premiums continue to rise.

Coastal communities face a significant challenge in attracting the leadership,

interagency governmental coordination, research investments, tool development, and

financial support for implementation of SLR adaptation strategies and policies.

Education and outreach about the situation are more at the “grassroots” level.

By and large, Norfolk property owners are “left on their own” to cope with mitigation.

Page 19: Applying Engineering Management Concepts to Sea Level Rise

14

Dynamic Complexity: Dynamic Complexity is marked by emergence in which the system

changes based on changes in the environment. There is much dynamism with

environmental, economic, and strategic assets at risk due to the consequences of climate

change. A large number of entities are involved in “satisficing” the situation (Federal,

state and local government agencies; insurance, financial and academic institutions;

property and business owners, etc.). Research studies have been commissioned to

evaluate the issues and implications, but there is no “problem lead.” The stakeholders must

come together now to address a complex problem regarding the planning, development,

and implementation SLR adaptation strategies for Norfolk.

Adaptivity: A higher degree of adaptivity is seen here as the overall system changes in

response to the changes in the context. For example, it is important to recognize the

implicit knowledge and insight of those who understand the context surrounding this

complex problem. However, in this particular scenario, the overall system adaptivity is

hampered somewhat by the lack of an overarching strategy.

Emergence: Overall this is a complex system, which exhibits internal elaboration with

evidence of emergence over time. The global effects of climate change are seemingly

irreversible and are expected to worsen over time. This will add further complexity to the

system. A “quick-fix” approach without considering the interrelated key elements will not

produce a meaningful outcome.

Project Assumptions: The following assumptions are applicable to this project:

Norfolk is a large coastal urban center located on low-lying areas prone to inundation.

The city will continue to be subjected to episodic flooding due to storms, but land loss

due to SLR-induced lateral erosion is permanent.

Page 20: Applying Engineering Management Concepts to Sea Level Rise

15

Norfolk’s coastal zone is defined by interactions between natural and socio-economic

systems. These interactions are both complex and dynamic.

Stakeholders can be identified with defined roles and responsibilities.

Technological tools are capable of generating data (encroachment, hydrodynamics,

and inundation) for vulnerability indices and mapping to determine high-risk areas in

the region.

An adaptation strategy can be tailored to specific applications and multiple

approaches may be combined.

SLR adaptation is an iterative process, which must be consistently revisited as new

information becomes available.

Project Limitations: There are several limitations associated with the approach to be

devised. Specifically, this project cannot:

Fully incorporate socio-economic analyses.

Develop the necessary policy, legislative, and regulatory modifications or identify the

funding sources and financial incentives to implement and sustain approved mitigation

approaches.

Represent the community and individual property owners’ legal frameworks and

administrative structures (zoning, permitting, tax basing, and legal restrictions).

Obtain the level of fidelity needed to be truly predictive for the number of Norfolk

enclaves and property owners that will need information.

Incorporate specific agreements, shared plans, and objectives between regional

observing and governance groups.

PROJECT APPROACH

Page 21: Applying Engineering Management Concepts to Sea Level Rise

16

Overview: This problem approach is organized to develop first the background for the

systemic view of SLR adaptation strategies for the Tidewater Virginia region. Second,

indicators are identified to properly frame the problem situation. Next, the nature of the

adaptation strategies is formulated using a systems-based perspective, which is the

foundation for the methodology. The methodology is then presented, discussed at recent

Hampton Roads SLR adaptation workshops, and applied to an individual, high-risk

property in Norfolk. Engineering management concepts (systems analysis and

knowledge management) will be used to formulate this approach.

Developing the Systemic Perspective: Application of Systems Principles There are three key principles that apply to this particular problem, and these help inform

the systemic perspective as follows:

Satisficing: There will never be an “optimal” solution for SLR adaptation, but one can be

found that adequately addresses the issue and “satisfies” the complex problem scenario.

This “satisficing” concept needs to be considered when aligning the context, framing,

approach, and expectations. Furthermore, identifying an appropriate solution must be

predicated on the available resources and the best probability of success for all

stakeholders, but particularly Norfolk landowners.

Transferability: SLR adaptation strategies must be transferable to all Norfolk property

owners, businesses and community planners. However, each application is unique, and

there is not a “one size fits all” approach on a tactical level. The policies, guidance, and

tools developed and implemented locally should be capable of being shared with other

coastal communities such as New Orleans, Corpus Christi, and Miami, which are

suffering similar destructive SLR-related impacts.

Page 22: Applying Engineering Management Concepts to Sea Level Rise

17

Sustainability: The solution must be capable of addressing the problem on both near-

term and sustainable bases. Climate change is making an indelible mark on the region

due to increased flooding, storm surges, shoreline erosion, and saltwater intrusion.

Unfortunately, the situation appears to be irreversible. Thus the research, planning, and

vulnerability studies ought to continue to ensure the City of Norfolk is best postured to

respond and take a leadership role in this global issue. A sustainable local strategy ought

to be the city’s primary objective. In turn, individual mitigation projects must be property

aligned with this strategy.

Analytical Strategy: The analytic strategy is the design for qualitative and quantitative

exploration needed to understand and make decisions concerning a complex problem.

It entails strategy formulation, data gathering, analysis methods, and data interpretation.

The strategy ought to provide a basis for “reframing” the problem if required.

Globally, a recent UN Conference on Climate change in Copenhagen underscored

that not enough is being done to support mechanisms between scientific knowledge and

adaptation policies in mobilizing stakeholders (people, businesses, and institutions) to

prepare for the negative impacts of rising seas. Multiple dimensions in the coastal system

include the bio-physical, economic, social, and institutional arrangements of coastal

communities (Lane and Watson, 2010).

Criteria are given relative to the broad definition of participating groups within coastal

communities: (1) governance and local policy makers, (2) public and private infrastructure

communities, (3) business and economic activity organizations, (4) citizens’ interest

groups, and (5) special interest groups (conservation and environmental). The analytical

approach captures and profiles community data via graphical information system (GIS),

Page 23: Applying Engineering Management Concepts to Sea Level Rise

18

which identifies sensitive areas to storm surge, erosion, and SLR. The decision model

compares among stakeholders alternative evaluations or community adaptation strategies

in the face of extreme weather conditions and provides a ranked group decision evaluation

procedure to assist decision-makers in operational and strategic negotiation and

evaluations (Paskoff, 2006).

Is the solution deterministic and probabilistic? No, but the situation can be improved. The

problem statement is formulated by information provided. Literature review is an

important part of problem solving. There are other coastal communities (nationally or

globally) experiencing similar challenges. Although the magnitude and specifics may

differ, the concepts are essentially the same. Lastly, any models formulated must be

tested with empirical data in the form of case studies to the maximum extent possible.

Systemic Perspective: What must be addressed to avoid a Type III system error?

This project focuses on local SLR adaptation strategies. The specifics involve analyzing

the dynamic factors to help Norfolk property owners and other stakeholders understand

the issues, perspectives and irrationalities to influence informed decisions. The systemic

approach applied in this scenario must take into account the following concepts:

Uniqueness of problem and context: An “off-the-shelf” approach will not likely work. Case

studies are available which examine strategies for SLR mitigation, adaptation, and

accommodation in other vulnerable areas in the United States. Some of the

circumstances, however, are unique to those particular regions and may not be fully

relevant to Norfolk stakeholders.

Page 24: Applying Engineering Management Concepts to Sea Level Rise

19

Human influences: Modeling and simulation are effective and can help develop

simulation methodology to determine which areas of a coastal community are most

vulnerable to destructive SLR effects. Also, these models will help identify some of the

interactions between natural and socio-economic systems. However, this logic and

science must be reconciled with “human” needs. In other words, irrationalities will be

introduced into the design. Decision-makers will have to determine the “best fit” based

on allocation of resources such as time, manpower, and finances. Regardless, these

approaches will not address the root cause of SLR (i.e., global warming and climate

change).

Iteration of understanding: An iterative decision-making process will produce plans in

which resources are converted into systems meeting human needs and solving problems.

The initial plan developed may require further data collection and processing, negotiating,

and problem solving.

Emergence (instabilities in the environment): As the design is being formulated, there will

be new instabilities (relationships, limitations, constraints, etc.) to consider. For example,

some of the socio-economic factors (population growth, coastal development trends,

insurance subsidization, effects on fisheries, etc.) may change, which will need to be

factored into the design process.

Compatibility: There must be compatibility among the problem, problem domain,

expectations and resources (M5I: manpower, material, money, methods, minutes, and

information). Ultimately, there must be shared stakeholder consensus.

Misclassification: The solution to an improperly framed problem can lead to costly

consequences (i.e., poor resource allocation, wasted time, etc.). For example, a

Page 25: Applying Engineering Management Concepts to Sea Level Rise

20

community decides to address shoreline erosion along a bay using coastal armoring (hard

structuring) to support the new development of luxury condominiums. One of the builders

contends that a seawall (coastal armoring) was used effectively to fortify a construction

project located alongside marshlands in another state.

Armoring is one of the oldest flood protection tools but is only engineered as a

short-term solution for a certain storm size and relative SLR change. Coastal armoring

must be designed by considering the system’s energy level (oceans, bays, rivers,

streams, watersheds, and marshes all have varying degrees of wind and wave actions).

The seawall must be monitored and maintained periodically to ensure its integrity.

Paradoxically, a seawall increases vulnerability. Hard shoreline protection is not

as effective as natural shorelines at dissipating the energy from wind and waves. This

makes these structures more vulnerable to erosion, and they actually promote erosion of

nearby unfortified areas such as beaches and natural sand dunes (Tam, 2009). The

structural flood protection can also increase human vulnerability by giving condominium

residents a false sense of security and further encourage development in areas prone to

flooding or storm surge damage. This puts more people and assets at risk.

In the end, this expensive countermeasure does not solve the problem. The

community property owners are unhappy because: (1) private beach owners adjacent to

the complex are coping with excessive shoreline erosion, (2) the seawall dimensions are

not being adjusted to accommodate new sea level baselines, (3) nobody is responsible

for maintaining the seawall, and it was ineffective in preventing the flooding of several

condominiums during a recent nor’easter storm.

Systems Model: Developing the right approach

Page 26: Applying Engineering Management Concepts to Sea Level Rise

21

Soft Systems Methodology (SSM) (Checkland, 1999). SSM is appropriate for ambiguous

problem statements with a higher degree of uncertainty using primarily qualitative data.

The problem system boundaries are not normally clearly defined, and the contextual

considerations appear in the foreground. Therefore, SSM applications are best used in

addressing an unstructured problem situation, describing it from as many perspectives as

possible, and using these discussions to develop cogent conceptual systems models.

These models are not used for developing an ultimate solution but rather for instituting

system change. The problem domains often defy those solved using hard systems

approaches with quantitative data collection exclusively.

SSM Benefits: SSM is used to embed the community and individual landowners to

establish local priorities, define the scope of the local research, pinpoint institutional

arrangements, involve decision makers and affected organizations, establish measurable

vulnerability and performance indicators, and develop decision alternatives. SSM is the

tool that addresses the issues with adaptation and sustainable development at the local

community level by acknowledging that human problems are complex and issue-based. It

employs a “participatory” approach requiring interdisciplinary collaboration to develop

solutions. This is accomplished using situational accommodation by community members

rather than through problem optimization. SSM seeks “common ground” through structured

debate on management where the need is for a system of inquiry and adaptive learning,

which reacts to events by responding to behavior rather than changing behavior patterns

and their underlying causes (Senge, 1990).

SSM Problems: SSM has its share of criticisms. First, it is not suited for the design of

complex system solutions where there is a high level of conflict. There is a danger of model

Page 27: Applying Engineering Management Concepts to Sea Level Rise

22

“supremacy” in which system experts could potentially create bias by considering their

models more correct or relevant to the problem situation. Additionally, bias can be

introduced via a lack of accountability in power, conflict, and irrationalities inherent in these

ill-structured problems. Conflicts of interest can be introduced at the expense of structured

discussions. Since SSM approaches are participatory in nature, inconsistent worldviews

generated by “homogenous” or “like-mindedness” among the stakeholders will tend to

break down the process. Moreover, the stakeholder must be capable of implementing a

SSM skill set and being a subject matter expert in the problem situation. Lastly, SSM is not

a panacea for addressing all messy, ill-structured problems. It must be tailored to the

situation and is not intended to be a rote application process.

SSM Application: SSM will follow the systems thinking in the seven stages defined and

described by Checkland (1999).

SSM Stage 1: Inquire into the (real world) situation.

Virginia has the highest rates of relative SLR recorded on the East Coast of the United

States (Harper, 2010). The Tidewater region of the state has significant economic and

strategic activities at risk from both current and future SLR projections. This increases

the urgency for coastal Virginia residents to execute SLR adaptive planning and

implementation with the support of federal, state, and local authorities. Presently there is

no single agency responsible for SLR policy, information or guidance to local

communities. Successful adaptation strategies will require all sectors (federal, state,

local, academic, non-governmental and private) to collaborate throughout the process to

provide local communities and homeowners with resources, scientific data, and political

support (Culver et al., 2009). The dynamic regional SLR situation, varying

Page 28: Applying Engineering Management Concepts to Sea Level Rise

23

interests/perspectives among the stakeholders, complexity accompanying interagency

coordination, and lack of concise guidance result in an inability to confront the issues

“concretely.” Hence there is the need for SSM.

SSM Stage 2: Describe the (real world) situation.

The Commonwealth of Virginia and many coastal communities have commissioned studies

and are carrying out local research related to SLR. The majority of these efforts are being

conducted by academic institutions like Old Dominion University, the Virginia Institute of

Marine Sciences, and the University of Virginia (Brighton, 2012). Adaptive strategy

“toolkits” are available to businesses and homeowners through non-governmental

organizations and conservation groups such as the Chesapeake Bay Foundation,

Wetlands Watch, Elizabeth River Project and The Hermitage Foundation. However, land

use decisions are the domain of local governments and as the inundation and erosion

threats grow in Tidewater Virginia, the local governments need the policy and tools to

develop, fund, and implement mitigation strategies. The situation is expressed by the

interactions between these elements in the “rich picture” below (Figure 1).

Page 29: Applying Engineering Management Concepts to Sea Level Rise

24

Figure 1: SSM “Rich Picture” of Interactions

The main issues to address in the SSM are the following: (1) define the SLR problem

situation for Norfolk property owners, (2) explore impacts on the built environment, natural

systems, and regional economy, (3) gather the data, information, and tools, (4) discuss

the approaches for adaptive planning and implementation, and then (5) build and sustain

capacity/support (Culver et al., 2009).

SSM Stage 3: Define relevant systems (“CATWOE” elements identified)

Clarity is acquired through viewing stakeholder perspectives, understanding their

implications, and using these insights to develop conclusions and recommendations for

future action. This stage helps to set up the system conceptualization using Checkland’s

“CATWOE” mnemonic as follows:

(C) Customers: Norfolk property owners, businesses, and community planners.

Page 30: Applying Engineering Management Concepts to Sea Level Rise

25

(A) Actors: Federal, state, and local agencies, local coastal communities, academic

institutions, financial and insurance agencies, non-government and private

organizations.

(T) Transformation: Strategic-level (regional) and tactical-level (community &

homeowner) adaptive approaches (i.e., living shorelines, hardened structures,

“aquatecture”, etc.) and SLR “adaption authority” organization.

(W) World View: Improve quality of life/quality of service in Norfolk by providing cost-

effective SLR adaptation strategies that minimize impact on the local economy and

native habitats (wildlife and wetlands), while increasing the resilience of both residents

and the built environment.

(O) Owners: Federal, state, and local governments and their associated agencies.

(E) Environmental Constraints: SLR tactical and strategic approaches might not be

economically feasible and may be unable to keep pace with the present rate of coastal

inundation and shoreline erosion. There may be incongruence between these

approaches in the specific application of problem areas (i.e., land use, storm histories,

“high-energy” versus “low-energy” shorelines, topography, bathymetry, existence of

protected wetlands, habitats, and species, etc.).

SSM Stage 4: Conceptual Modeling

The model consists of the various terms and concepts previously defined in the paper.

Moreover, Lane and Watson (2010) suggest proper modeling simulation requires three

additional groups of parameters:

Visual/Spatial Mapping: Integrated dynamics of the ecological, socioeconomic and

cultural subsystems can be developed using Geographical Information Systems (GIS)

Page 31: Applying Engineering Management Concepts to Sea Level Rise

26

software and Google Earth to produce maps, graphs and tables to support analyses.

Mapping is used to simulate/animate storm events supporting community/small group

discussions to help make informed decisions regarding mitigation strategies.

Vulnerability Assessment: Community vulnerability indices are devised using static

and dynamic mapping. These are weighted by the detrimental impacts assessed to

natural systems and economic bases (i.e., loss of property, infrastructure damage,

cleanup/rebuilding costs, etc.).

Adaptive Capacity & Resilience: Models the communities’ aptitude to develop and

implement strategies for environmental changes, which are determined by: (1)

technological options, (2) available resources, (3) structure and decision-making, and

(4) ability to manage information. Adaptation is constrained by the resilience of

“natural” systems in evolution with “human” systems. Resilience refers to the coping

ability of the adaptive capacity of the affected community to recover from a damaging

external impact (flooding, storm surge, erosion, etc.).

The objective of models is to provide a means to structure debate about a problematic

situation. This conceptual model construct is depicted in Figure 2 on the following page.

Figure 2: Conceptual Model of SLR Adaptive Planning & Implementation

SSM Stage 5: Comparing conceptual model with real world

The conceptual model enables the development and assessment of policy options for

decision-makers. These complement the participant-based SSM to identify areas of

agreement to further investigate and prepare for future environmental scenarios.

Performance indicators can assess the ongoing spatial and temporal status of coastal

properties at risk from adverse environmental effects. Stiles (2010) asserts that the

models will influence the adaptation plans to cope with the SLR risks in Southeastern

Virginia. If the risks become more severe over time, then financial incentives, carefully

planned infrastructure investment, and regulatory programs can be aimed at the high-risk

zones to minimize property owners to the probabilities of higher inundation. Moser (2005)

suggests that uncertainties in the human dimensions of global change deeply affect the

responses to climate change impacts such as SLR.

Page 33: Applying Engineering Management Concepts to Sea Level Rise

28

SSM Stage 6: Debate desirable and feasible change

There are several required elements of local government adaptation strategies for SLR,

erosion control, and storm surge protection. The first requirement is public support and

awareness, especially from private landowners, who possess the majority of the properties

in and around Virginia shorelines. Second, technical resources need to be sufficient to

focus and prioritize local government efforts. This information will help to influence

planning, land use, incentives/disincentives, direct investment, and public infrastructure.

Third, financial resources must be made available to meet the adaptation strategy identified

(living shoreline, barrier, coastal armoring, planned retreat, etc.). Direct funding and tax

credits may be needed to either purchase vulnerable properties or secure development

rights/easements on private properties. Financial compensation will be required. Lastly,

localities within Norfolk must have programs available to execute adaptive planning. To

ensure success, they must also have the “regulatory authority” to place conditions on land

use options. This authority would be the responsible point of contact to help communities

and individual property owners navigate the process as well as shepherd the research,

policy, guidance, and funding processes.

SSM Stage 7: Implement changes

The final stage is assigning and implementing action from proposed changes in the previous

stage. SSM rests on the assumption that changes identified as systemically desirable are

easier to implement than final solutions derived through “hard” technology focused systems

thinking. Regardless, these changes have to be implemented in a clear, measureable way

and translated into planned service objectives. This may entail a change to business rules

and close communication between all the involved agents. The key to developing an

Page 34: Applying Engineering Management Concepts to Sea Level Rise

29

effective system is to ensure participation by all the key stakeholders. Stiles (2010) suggests

that a “toolkit” using an organizational approach can bundle the adaptation program for local

governments, businesses, property owners, and planners into functional categories as

follows:

Presentations creating awareness of and preparation for climate change impacts

(planning tool).

Programs providing monetary incentives to influence behavior to mitigate risks; secure

funds for the projects increasing the SLR risks to infrastructure and natural resources

(financial tool).

Procedures that prevent or redirect land use decisions so as to reduce the risks of

climate change (regulatory tool).

A board, activity, or agency appointed to coordinate community and individual

adaptation strategies to include data packaging, processing, and funding

assistance/authorization (planning, financial, and regulatory tools).

The next step must entail using these tools to begin SLR adaptation work today and make

the process more effective through prompt legislative and regulatory changes.

PROJECT RESULTS AND IMPLICATIONS

Data Interpretation: Methodology Outputs

One of the project’s objectives is to develop a methodology to address a complex problem

such SLR adaptation. The methodology, in turn, must then be capable of satisfying the

other project’s other objectives. More specifically, the results and implications of this project

are specified in terms of outputs formulated from the SSM approach. These include the

following criteria in Table 2 (Lane and Watson, 2010):

Application of the Methodology: The methodology captures and provides local

community data using the Geographical Information System (GIS) and identifies high-risk

areas to SLR and storm surge. The decision model illustrates, displays, highlights, and

confirms among the participants the evaluation of SLR adaptation strategies subjected to

extreme weather simulations (hurricanes and nor’easter flooding events) to aid decision-

makers in operational and strategic negotiations and evaluations.

This methodology was discussed at two workshops on 16 November 2012 (hosted

by Old Dominion University) and 13-14 February 2013 (hosted by the Virginia Institute of

Marine Sciences and Wetlands Watch), and then applied to an existing case study of a

Page 36: Applying Engineering Management Concepts to Sea Level Rise

31

high-risk property in Norfolk, Virginia. The workshops discussed the innovation and

adoption of best practices for reckoning with SLR issues in Hampton Roads. Specifically,

one breakout group explored the effectiveness of adopting and implementing actual

adaption activities to enable adaptive management among Tidewater Virginia

municipalities and individual property owners. The outputs developed by the methodology

are discussed in terms of enablers and constraints, and they are applied to the high-risk

property in Norfolk.

Overview of the application: The methodology was used in a specific application (a high-

risk property) to evaluate its effectiveness. The term “high-risk” is used here to describe

Norfolk residential properties, which have repetitively experienced damage/material losses

and amassed a progressively higher number of insurance claims due to episodic flooding

caused by the effects of SLR (City of Norfolk Letter, 2012). Engineering management

concepts such as engineering design, environmental planning, and project management

are utilized in this application.

Property description: The property is located in Norfolk, Virginia, and has been subjected

to the deteriorative forces of shoreline erosion since it was built in 1984. The site is situated

on the Lafayette River watershed in the city’s Larchmont section. In recent years the

erosion problem has been exacerbated by combined effects of rising diurnal tides and

recurring destructive weather patterns (i.e., Nor’easter storms in 2007 and 2009 and

Hurricanes Isabel, Irene, and Sandy). The combined effects of these events have caused

the loss of about 145 square feet of dry land property since April 2005.

The progressive water levels and significant shoreline encroachment have put a

single-car detached garage in jeopardy of structural weakening due to water damage.

Page 37: Applying Engineering Management Concepts to Sea Level Rise

32

This garage may have to be dismantled or relocated within the next five years in view of

present trends unless this erosion issue is addressed via an adaptive strategy.

Furthermore, the shoreline erosion is occurring along protected wetlands, which provides

a critical habitat to threatened flora and fauna. Thus this location is subject to strict

regulations excluding projects that create wetland environmental disturbances. The

property is located in an “A4 flood zone,” meaning that it has at least a 26% chance of

flooding out the house over the lifespan of a 30-year mortgage. SLR-induced effects are

starting to impact property values, and the ability to contract for flood insurance coverage

by the Federal Emergency Management Agency (FEMA) is more problematic.

Output Enablers and Constraints: This systems-based methodology does not solve the

identified systemic issues. Rather, it makes important contributions to the SLR adaptation

strategy for an individual landowner or community planner. The following results are

offered using the five outputs:

First, the knowledge creation and communications, co-learning and decision-

support tools desired outputs were enabled via website literature reviews and site surveys

conducted at local SLR remediation projects. These sites employed different techniques

to help inhibit coastal erosion on low-energy systems (minimal wind and wave action) using

a range of armored structures (bulkheads and revetments) and living shorelines. The

dozens of sites visited were all on public record and could be accessed by referrals and

websites. The projects most comparable to this one used the living shoreline methods.

Two local precedents were the 46th Street (and Colley Avenue) Wetlands Restoration

Project <http://www.lrwpartners.org/LWP/46th_St_Wetlands> and Virginia Zoo Wetlands

Project <http://www.virginiazoo.org/documents/Wetlandsfactsheet>, both of which share

Page 38: Applying Engineering Management Concepts to Sea Level Rise

33

the same waterway with this particular property in Larchmont. Subject matter experts

who designed and implemented these projects discussed the use of biodegradable

structural materials and herbaceous plants to help rebuild or “supplement” the wetlands,

which have a natural propensity to absorb floodwaters and curb shoreline erosion. These

outputs were constrained by the informal context of the process. Specifically, there are

multiple organizations, references, and websites containing information but no specific,

“one-stop-shopping” for projects of this type. Rather the Norfolk property owner has to

perform all the research and seek consultation individually without the assistance of a

centralized authority or agency.

Next, the monitoring and evaluation indicators were established through

environmental modeling and simulation. Visual mapping using the Geographical

Information System (GIS) is the best tool, and it can provide the property owner with state-

of-the-art vulnerability data based on present and predictive SLR related activity.

However, in the process of executing this output, the flood insurance rate map (FIRM)

was found to be incorrect for the high-risk property used in this application. It is the official

map of the community on which FEMA delineates special hazards and risk premium

zones. The flood zone characterization on the deed was taken from inaccurate FIRM

data, and the property had insufficient flood insurance coverage. Although this error was

discovered and is in the process of being corrected, it underscores the importance of

monitoring as an iterative function. Thus, a constraint to vulnerability data is that risk

assessments and monitoring indices must be updated periodically due to the dynamic

nature of climate change and SLR, as well as their overall effects on the region.

Page 39: Applying Engineering Management Concepts to Sea Level Rise

34

Third, the training output was enabled through many no-cost, informal workshops

offered by academic institutions, environmental organizations, and non-profit interest

groups. This training uses subject matter experts to discuss the highlights of local

adaptation projects and recommends certain techniques to ensure implementation

success. However, the major constraint is that there is no hands-on training unless an

individual desires to perform on-the-job training with volunteers, paid consultants, or

environmental construction companies. Additionally, the laborious joint permit application

(JPA) required for these types of projects can be confusing, but it can be successfully

completed by referring to on-line resources.

The remaining two outcomes, adaptation action plans (AAPs) and central SLR and

flooding agent, have not been created and could not be assessed as enablers. Therefore,

until these desired outcomes are developed and implemented with responsible

individuals, they will continue to be constraints to the process.

PROJECT MANAGEMENT: “Roadmap” for Norfolk Property Owners

Overview: Engineering-based project management is used to develop the design goals,

critical knowledge factors, stakeholder analysis metrics, design specifications, work

breakdown structure (WBS), program evaluation and review techniques (PERT) including

critical path activities, resource loading matrix, and budgeting for this specific application

in Norfolk.

Design Parameters and Specifications: The following details are provided as key

project management and design elements for this “living shoreline” treatment project.

These parameters are needed to plan and execute this type of SLR adaptation strategy.

Page 40: Applying Engineering Management Concepts to Sea Level Rise

35

Design goals: The goals for this specific application are to mitigate the detrimental effects

of SLR-induced flooding and erosion by: (1) using the minimum amount of structural

protection necessary; (2) having high potential to achieve wetlands restoration; (3) having

high potential to significantly improve wildlife habitat; (4) offering innovation to wetlands

protection, restoration, and management methods; (5) providing monitoring and

evaluation of restoration activity effectiveness, and (6) incorporating all the previous goals

at a reasonable cost (assuming that Federal, state and/or local compensation will not be

an option). The general assumptions for developing a SLR adaptation project for Norfolk

home and property owners are specified in Appendix A.

Critical knowledge factors: The understanding of permit laws and regulations, site

observations and evaluations, structural erosion control components, and selection of

vegetation are the four (4) key critical knowledge factors considered for this particular

project. Appendix B shows why these knowledge factors are essential to the project,

details the sources and creation methods, and identifies the respective transfer media.

Stakeholder analysis: It is important to identify the following stakeholder influences

present in this application: (1) alignment of interests, (2) linkage to the project, (3) power

over execution and deliverables, and (4) project management experience. Appendix C

examines the interactions of the stakeholders specifically identified to execute action in

this “living shoreline” treatment application. Naturally, larger projects of this type would

require a broader range of stakeholders (especially those carried out on public lands).

Design specifications: The use of natural alternatives was chosen for this particular

application. The waterfront is subjected to low-energy wave and wind actions, so a “living

shoreline” could best absorb the impacts of SLR-induced erosion and best function like a

Page 41: Applying Engineering Management Concepts to Sea Level Rise

36

“sponge” to absorb floodwaters. The shoreline along the property can be “hardened” by

biodegradable structural components and (re)planting wetlands vegetation.

Aesthetically-pleasing vegetative techniques are preferred when combined with other

natural alternatives to help counter erosion while minimizing wetland disturbances.

Native plants and wetland-friendly vegetation are naturally adapted to the area’s

characteristics (soil, climate, pests, and temperature ranges). These plants are easier to

grow and require minimal upkeep. Moreover, a border of these plants (fringe marsh) can

act as a buffer to slow down the flow of run-off water and provide a natural filter for

impurities. The technical details are specified in Appendix D, and these include the

project site (highlighted as an overlay on the property survey), plan view, and cross-

sectional drawings. The plan was developed to satisfy the design goals using the

knowledge factor and stakeholder inputs. Figures 3 and 4 provide an overview of the

work breakdown schedule (WBS) for project activities and their corresponding

(alphanumeric) event, while the program evaluation and review technique (PERT) for

activity sequencing is presented in Figure 5.

As per Figure 5, the living shoreline project is to be carried out in three distinct

phases: research and information gathering, construction and planting, and post-

execution monitoring and education. The first phase is consists of knowledge acquisition,

consultation with subject matter experts, and permit authorization. The next phase

incorporates the key preparatory and site labor, which includes soft-structure installation

as well as the planting of native vegetation. The final phase involves post-construction

inspection, evaluation and maintenance as well as providing outreach to/lessons learned

for other Norfolk property owners.

Figure 4: Project WBS activities specified by event.

Critical path activities and resource loading: Prior to determining the critical path activities

for this application, the estimated normal time using the optimistic, pessimistic and most

likely time completion is calculated for each WBS activity (Appendix E). The critical path

activities are shown in Appendix F. In referring to the PERT charts, the living shoreline

project should be accomplished in 336 days with a 97.9% probability of completing it

within one year (365 days) as per Appendix G. The overall project duration is about 48

weeks, which differs significantly from the 68 weeks estimated in the project proposal.

This divergence is due to inaccurate estimates regarding the time period required

between steps in the permitting process as well as availability and delivery of custom-

made structural materials.

Page 44: Applying Engineering Management Concepts to Sea Level Rise

39

Figure 5: PERT graphic for project activities by event.

A resource loading matrix for each phase (Appendix H) gives the specific WBS activity

duration (overall for each item and in time units per week).

Budgeting: Appendix I shows the time-phased and WBS-based project budgeting. The

total cost of installing a living shoreline on this property is calculated to be $2274.96.

There are some longer lead-time items (i.e., permit approval, material procurement, and

maintenance) required for the plan, which are based on conservative estimates. Crashing

can reduce the material acquisition time, but the other critical path activities are

dependent upon other external factors such as agency review processes and favorable

weather conditions.

Design issues: The following issues had to be reconciled with the original plan:

JPA design parameters: The original design plan was inadequate for the initial permit

application and needed modification. Specifically, only a plan view drawing was

submitted when a cross-sectional view was also required (added to WBS 1.1.1.2.2.1).

This second submission had to show the mean range of tides, elevation, and slope of the

property as well as the proposed location of the coir logs, substrate fill, and installed

vegetation. This step could be accomplished without delaying the approval process.

Site observation: An essential element of the project planning entailed a site observation

(WBS 1.1.1.1.2.1) to determine the impact on the site’s flora and fauna. An abandoned

mallard duck nesting area was discovered close to an area that was to be cleared, graded,

and replanted. Mallard hens tend to be “philopatric,” meaning they may return to the site

of previously successful nests. Consultation with bird experts deemed that on-site work

could be conducted if no hatchling/duckling activity is present.

Debris removal: This activity (WBS 1.2.1.2.1.2) included removal of invasive plant

species. Specifically, the site had a non-native marsh reed (phragmites australis), which

reduces the diversity of plant and wildlife species. It was discovered that physical

eradication was not enough and chemical treatment would also be required to inhibit its

return. This condition may also impact site long-term maintenance (WBS 1.3.1.1.2.1).

PROJECT EVALUATION AND RECOMMENDATIONS

The next step entails an evaluation of the results and implications. First, the factors for

complex systems failures are explored. Next the discussions will cover the interpretations

of the overall approach developed using SSM and apply the evaluation criteria to the

specific application. The long-term and short-term assessments of the “living shoreline”

treatment project will be discussed. Lastly, the paper concludes with the implications and

limitations of the methodology and recommends the way ahead for this approach.

Complex Systems Failure: What can go wrong and why?

There are some possible conditions in the project that could cause it either not to meet or

unacceptably diverge from its specified or implied performance requirements.

Regardless the goal is to identify these, preferably prior to failure.

Page 46: Applying Engineering Management Concepts to Sea Level Rise

41

Design, deployment, or operational failure: Models will not always obtain the level of

resolution needed to be truly predictive for the many communities requesting the

information. Therefore, they should be used as scenario-generators to inform individual

SLR adaptation strategy selections. Examining a range of scenarios will enable the

community and local property owners to understand the priorities. A robust solution is

one that meets the minimum number of criteria across a broad spectrum of characteristics

(Culver et al., 2010).

Contextual alignment or integration failure: The verification phase of the models could

fail in their transformation from input to output. In other words, the boundaries, entities,

and parameters (any one or all of them) could be determined incorrectly. In particular, the

SSM approach validation may not be a viable alternative to actual experimentation.

Indirect impacts: The analytical approach here cannot possibly address all the indirect

impacts of a SLR adaptive strategy, which are more difficult to identify and analyze. For

example, a hardened structure, such as a levee, was built to fortify coastal development.

But it can negatively impact the local ecosystems. Although the levee benefits the

homeowners and businesses, the costs are extracted elsewhere. Specifically, the

reduced sediment supply, morphological changes, and impeded drainage created the

demise of adjacent wetlands. The receding marsh-water interface interrupted the life

cycles of many fish species and affected the yield at the local fisheries. So there are both

environmental and socio-economic consequences of this particular method. This

example underscores the need for an environmental impact study to be integrated into

the process to help identify the non-linear effects posed by the implementation of the

particular SLR adaptation strategy.

Page 47: Applying Engineering Management Concepts to Sea Level Rise

42

Failure to manage risk: All projects have risks, which are the possible undesired events

that could result in the failure to meet one or more of the project’s objectives. The most

important aspect of project risk management entails identifying which risks are most

severe and then evaluating their impact on the project. In the case of the “living shoreline”

treatment project on the high-risk property in Norfolk, the risk management was assessed

using four (4) risks that could cause it to fail: regulatory/permit rejection, survival of the

planted vegetation (flora), water/storm damage, and design failure. Quality, schedule,

and season/weather were three (3) dimensions with which to measure the impact of these

risks. The scales for both risk impact and the probability of occurrence were determined

for each of the four risks identified above. The overall project risk factor was determined

to be “medium” (the specific values and equation are provided in Appendix J). However,

risk management evaluation is an ongoing process throughout the project’s lifecycle.

Thus the hazards and safeguards must be revisited periodically to minimize the

probability of project failure.

Framework for Project Evaluation: Common to all the SLR adaptation strategies is a

host of adaptive tools which are analyzed by the following:

Power needed to execute them (i.e., planning, regulatory, spending, tax tools)

Policy objectives being addressed (i.e., protection, preservation, retreating methods)

Existing or potential land uses (i.e., critical infrastructure, developable lands)

The trade-offs among tools are then assessed against relevant metrics. The trade-offs

will be defined in terms of evaluation criteria (Grannis, 2011) provided in Table 3. This

framework evaluation will enable decision-makers (community and individual

landowners) to consider the viability of the individual SLR adaptation strategy desired.

Page 48: Applying Engineering Management Concepts to Sea Level Rise

43

Table 3: Evaluation criteria for SLR adaptation strategies

Evaluation criterion Description

Economic - Strategy’s economic benefit (public and private) - Minimizes: (1) loss of critical infrastructure, (2) costs to design, implement, insure and maintain, and (3) economic disruptions

Environmental - Minimizes impacts on natural resources and ecosystems - Enhances autonomous adaptation processes - Safeguards existing wetlands and critical habitats

Social - Maximizes protection to people and property - Implements a strategy that results in unintended consequences for other public or private property

Administrative - Technical, fiscal, and political feasibility - Minimal administrative complexity and likelihood of permits - Flexibility in response to range of SLR-induced hazards

Legal - Implements strategy within existing authorities - Potential for legal barriers or liabilities

Recommendations and Implications at the Local Level

Applying this framework to the erosion control case in Norfolk, the evaluation of the

strategy can be obtained based on the criteria defined above. Figure 6 depicts this

evaluation using a stoplight chart employing several tools defined by Grannis (2011),

Stiles (2010), and Volk (2011). The SLR adaptation strategies having the best success

for permits locally are the “living shoreline” treatments, beach nourishment, tidal marsh

enhancement, and marsh sills. These methods best address the erosion control

problems in lower energy situations by having good potential for long-term protection,

shoreline restoration, and enhancement of vegetated habitats. The “living shoreline”

treatment has the best benefits for this specific application because it has the best

possibility of reducing bank erosion to the affected site and the neighboring properties.

The use of biodegradable materials helps improve marine habitat and spawning while

enhancing the water quality. Lastly, this treatment also has the most affordable

construction costs of all the planned adaptation strategies discussed earlier.

Figure 6: Evaluation Criteria Applied to High-Risk Property in Norfolk, Virginia

The specific application used throughout this paper could be considered as part of a larger

local strategy (once it is formally developed). Thus it must be assessed using the above

evaluation factors along with short-term and long-term assessments as follows:

Short-term: This “living shoreline” treatment project’s success will be gauged by its

feasible completion within time and budgetary constraints. From start to finish, it should

be completed within about 48 weeks. There are two critical path activities (WBS

1.1.2.1.1.2 and 1.2.1.1.1.1) having the longest dwell times. The first activity is joint permit

application (JPA) approval, which is a bureaucratic process that cannot normally be

expedited due to the generally high number of caseloads within the responsible agencies.

Second is procurement of the organic structural components. These materials are made

from coconut husks cured in water and are made to order. The manufacturer could

accelerate these items by about two weeks (for about a 15 to 20 percent increase in cost).

Page 50: Applying Engineering Management Concepts to Sea Level Rise

45

However, the Norfolk property owner might decide not to act or may execute

another strategy if the costs (time, effort, money) outweigh the benefits. In discussing

this with other homeowners experiencing similar effects, their first inclination is to “harden”

the shorelines with railroad ties, bulkheads and revetments. Others see that the “living

shoreline” treatment has distinct advantages but are more reticent to devote the effort

needed toward site maintenance. Therefore, an outreach program laying out the “pros”

and “cons” is important to ensure Norfolk homeowners and community leaders have the

most accurate data available to them to make an informed decision.

Long-term: The long term advantage of the “living shoreline” treatment is that it is

sustainable with minimal maintenance required once the plants have matured past at

least two growing seasons. If the plants are native species, they will be able to thrive in

the environment and germinate on their own toward self-sustainment. There is no proof

that residences with a “living shoreline” or some other type of soft hardening (beach

nourishment or natural waterline revetment) are assessed at higher property values.

Realtors have yet to use these as selling points when the properties are put up for sale.

If homeowners using these treatments can convince their neighbors to do so, then this

will be proof that a local strategy works. Ideally, multiple homeowners along a particular

waterway using a single SLR adaptation strategy would lend itself better to the cause.

Local Level Implications and Recommendations as a Result of the Project

Developing the SLR Adaptation Plan & Authority for Norfolk, VA: To date, the SLR

adaptation strategies in Norfolk have been carried out predominantly at individual levels

using data produced by science and research without supporting an overarching strategy.

Mitchell (2012) claims that in areas where government takes little or no action, individuals

Page 51: Applying Engineering Management Concepts to Sea Level Rise

46

will be left to take action to protect their own properties. So where is the appropriate level

of action needed to help control the number of disparate, ad hoc SLR mitigation projects?

Efforts at the federal or state level may be too general to address the local conditions and

concerns. Culver et al. (2009) assert that the regional level is the “sweet spot for

adaptation planning.” Thus planning ought to be both formulated and integrated at the

local level under the auspices of a local authority or agency. Without this, the

implementation of individual projects may be ineffective or even harmful. For example, if

one area protects its shoreline while the neighboring localities do not, then it is likely that

all of them will flood or be subjected to accelerated erosion.

Stages of protection: Policymakers must consider three stages when developing an

overarching local SLR adaptation strategy. First, the level of protection versus degree of

risk must be considered. Next, the planning horizon must be identified. For example,

should the strategy support minimizing risk in response to the 1 in 20 year storm?, 1 in 50

year storm?, 1 in 500 year storm?, or 1 in 5000 year storm? Finally, the strategy should

be able to dissolve the risk into distinct steps (Mitchell, 2012).

Coastal Zone Management: The concept of locally integrated coastal zone management

is a good basis for an urban policy. It considers the expected SLR and sets up a program

of action for sustainable development (Culver et al., 2009). Before coastal zone

adaptation strategies can be developed, tools for mapping shoreline flooding hazards

must be accurate and updated periodically. Imprecise or incomplete topographic and

bathymetric data are the primary causes for inaccurate flood models. If the data is

incorrect, then the result will be inaccurate Base Flood Elevations, which are used to

establish insurance premiums.

Page 52: Applying Engineering Management Concepts to Sea Level Rise

47

Community profiles: Lane and Watson (2010) suggest community profile databases

ought to capture the risks from SLR effects, and these should be guided by structured

development of resource inventories including physical, economic, and social capital.

The data consisting of base maps, storm histories, topography, and coastal hydrography

can be useful for assessing outcomes and projecting the likelihood of real threats to

regional infrastructure, environments, and economies.

Implications and Recommendations Beyond the Local Level: A range of further work

that would be particularly useful to policymakers can be identified to include the following

topics (Nicholls, 2003):

Continued development of local, regional, national, and global impacts and

vulnerability assessments of coastal areas. Studies will provide more detailed

knowledge and allow validation of regional and global integrated assessment models.

This will promote further quantification of the impacts of SLR, including more

consistent identification and mapping of vulnerable “hot spots.”

Consideration of the impacts of other climate change as well as the broader

implications of global change for the coastal zone.

Continued assessment of the adaptation process in coastal zones.

All the studies above would need to be supported by:

Modifying existing data and guidance on impact and vulnerability assessments.

Developing more robust databases on global coastal zones as existing data is not

ideal for integrated assessment.

Conceptualization, validation, and strategic visioning through a social learning

process.

CONCLUSION AND DISCUSSION OF DELIVERABLES

The following précis provides the status and content of each of the project deliverables.

First, this paper advocated that a systems-based approach can be applied to a complex,

“wicked” problem like SLR-induced challenges for Norfolk Virginia property owners. Next

the nature of the adaptation strategies was formulated using soft systems methodology

(SSM), the most appropriate means for addressing problems having higher degrees of

uncertainty. The specifics for developing the methodology involved analyzing the

dynamic factors to help regional property owners and other stakeholders understand the

issues, perspectives, and irrationalities to influence informed decisions. Project thinking

was important for effective systems organization to achieve complex problem resolution.

Although disciplinary knowledge and technological expertise were key enablers, it

was vital to understand the insights and contributions of those who comprehend the

problem context to ensure the legitimacy of the outputs. Thus knowledge management

during two interactive workshops fostered collective action through participatory

engagement thereby enabling stakeholders to move towards a common goal to institute

system change. An iterative decision-making process produced plans in which resources

are converted into systems, meeting human needs and solving problems.

A specific application of this methodology was used on a high-risk property in

Norfolk’s Larchmont section. Engineering management concepts such as project

management, engineering design, and environmental planning were used to carry out an

individual “living shoreline” treatment project. This application was laid out as a “road

map” to influence other local property owners to decide upon this particular SLR planned

adaptation strategy, which is financially reasonable and provides good erosion control

Page 54: Applying Engineering Management Concepts to Sea Level Rise

49

benefits while enhancing the natural shoreline habitats. Since most properties on Norfolk

are built around tidal marshes and wetlands, the assumption for employing this treatment

is very feasible.

The paper discussed some of the reasons for complex systems failure both

macroscopically and at the individual project level. Failure can occur at various stages in

the process: design, deployment or operational failure and/or contextual alignment, or

integration failure. Risk analysis for the specific high-risk property project was performed

using four risk factors along three dimensions that could lead to project failure. Moreover,

the project evaluation used economic, environmental, social, administrative, and legal

assessment criteria with each of these terms being defined within context of the project.

The most important challenge presently facing Norfolk residents is the absence of

a “go-to” centralized authority and comprehensive plan regarding SLR issues. Thus

Norfolk property owners must carry out their own individual projects executed more in a

piecemeal, ad hoc fashion, which are normally not part of an overall community

adaptation strategy. The paper discussed some implications and provided logical

recommendations for addressing this issue.

APPENDIX D: “Living Shoreline” Treatment Technical Specifications

The project will use biodegradable coir logs, sand for substrate composed of less than 10

percent clay, and a variety of herbaceous plants and grasses native to the local wetlands.

Coir products are fibrous, natural materials manufactured from coconut husks cured in

water. The erosion control area consists of about 54.2 feet of linear shoreline, and the

assembly will extend from the shoreline to about 3-5 feet into the waterway (minimizing

water flow obstructions). Five coir logs (BioD-Roll 30) are 1 ft x 10 ft each and will be

fitted in a loose row parallel to the shoreline with each side anchored every 2.5 feet by

wooden stakes and secured with twine. Coir matting (700 g/m2 mesh; BioD-Mat 90), will

be laid out along the cleared grade on the landward side of the mean low waterline. Sand

substrate will be used as fill between the logs and shoreline. The vegetation will be

planted in the coir logs, the filler substrate, and landward along the waterline in the

matting. Marsh elder (iva frutescens) shrubs will be introduced at or slightly above mean

high water mark. Cordgrass (spartina alterniflora) will be emplaced from the mid-tide line

(to seaward). Since the site is on a tidal mudflat with brackish water, both of these plants

have a high survival rate, provide food for and cover to a variety of native birds, and have

excellent erosion control and soil stabilization characteristics.

APPENDIX G: Probability of Completing “Living Shoreline” Project on Time

In referring to the PERT charts, the expected time to complete the project is 336 days.

So µ = 336 days.

Critical path activities have been identified as B-C-D-F-H-I-O-P-Q-S-U-V-W.

Standard deviation of each activity is determined by the formula: σ = (p – o)/6.

Variance of critical path (CP) activities is σB-C-D-F-H-I-O-Q-S-U-V-W = ∑σcp2 = 203.86 days2.

The standard deviation of the CP activities is √∑σcp2 = 14.28 days

Ideally, the project must be completed within one year (365 days). So the deadline is

set at P = 365 days.

Using the Z statistic, a probabilistic analysis can be performed as follows:

Z = (P - µ)/ √∑σcp2 = (365 – 336)/14.28

Z = 2.03

Referring to Standard Normal Cumulative Probability Tables, for Z = 2.03, the

probability is 0.9788.

There is a 97.88% probability of completing the project within the 365 day timeframe.

APPENDIX J: “Living Shoreline” Project Risk Management Assessment

The erosion control project has four (4) risks that can cause it to fail:

1. Regulatory/permit rejection (RPR)

2. Survival of flora (SF)

3. Water/storm damage (WSD)

4. Design failure (DF)

There are three dimensions to measure the impact of these risks:

1. Quality (Q)

2. Schedule (S)

3. Season/Weather (SW)

Scale of the probability of occurrence (Po):

Po RPR SF WSD DF

Low (0.1)

All natural means; minimal wetlands impact

Native plants and grasses

Regular diurnal tides & normal precipitation

Simple: easy acclimation & sustainability

Medium (0.5)

Mix of natural & artificial means; minor wetlands disturbances

Mix of native and exotic plants

and grasses

Mix of tidal fluctuations;

short heavy rain periods

Standard: more detail & requires greater upkeep

High (0.9)

Mostly manmade structures; major wetlands impacts

Mostly exotic plants and

grasses

Irregular diurnal tides; abnormal

rain/storm surge

Complex: difficult to execute &

maintain

The scale of risk impact (Ri):

Ri Q S SW

Low (0.1)

Minimal quality impact; good project results

No impact on critical path activities

Conducive to planting, construction & maintenance

Medium (0.5)

Moderate quality impact; results usable

Moderate impact on critical path activities

Conducive to construction; some

impact on planting & maintenance

Page 83: Applying Engineering Management Concepts to Sea Level Rise

78

High (0.9)

Results not usable Time goals not met Not conducive to

construction, planting or maintenance

The erosion control project has four (4) risks that can cause it to fail:

1. Regulatory/permit rejection (RPR): Natural means with no inorganic (artificial)

structures. Minimal disturbance to wetlands.

2. Survival of flora (SF): Native plants, seedlings and grasses.

3. Water/storm damage (WSD): Probable instances of irregular storm surges and

periods of heavy rain and tidal fluctuations (i.e., nor’easter season)

4. Design failure (DF): Design is simple to install and maintain.

Risk, probability assessment, and risk value assigned are summarized by the following:

Risk Probability assessment Risk value assigned

RPR Low 0.1

SF Low 0.1

WSD Medium 0.5

DF Low 0.1

The erosion control project has three (3) dimensions to measure the impact of the risks

should they materialize:

Regulatory/permit rejection (RPR) impact on the following:

Quality: low (0.1)

Schedule: medium (0.5)

Season/Weather: low (0.1)

Survival of flora (SF) impact on the following:

Quality: high (0.9)

Schedule: low (0.1)

APPENDIX J: “Living Shoreline”

Project Risk Management Assessment

Page 84: Applying Engineering Management Concepts to Sea Level Rise

79

Season/Weather: low (0.1)

Water/storm damage (WSD) impact on the following:

Quality: high (0.9)

Schedule: medium (0.5)

Season/Weather: low (0.1)

Design failure (DF) impact on the following:

Quality: high (0.9)

Schedule: low (0.1)

Season/Weather: low (0.1)

The overall project risk factor (OPRF) is calculated using the following equation:

Po = (0.1 + 0.1 + 0.5 + 0.1)/4 = 0.200

Ri = (0.1 + 0.5 + 0.1 + 0.9 + 0.1 + 0.1 + 0.9 + 0.5 + 0.1 + 0.9 + 0.1 + 0.1)/12 = 0.367

OPRF = Po + Ri – (Po x Ri) = 0.494

Criteria for determining OPRF is as follows:

Low: 0.000-0.299

Medium: 0.300-0.699

High: 0.700-1.000

Therefore, this endeavor can be considered a MEDIUM risk project.
