Planning for Resiliency: Evaluation of State Hazard
Mitigation Plans under the Disaster Mitigation Act
Philip Berke1; Gavin Smith2; and Ward Lyles3
Abstract: State mitigation plans play a critical role in supporting disaster loss reduction and long-term resiliency of human communities.
The Disaster Mitigation Act of 2000 requires all states to prepare mitigation plans. Based on six principles of plan quality, we content
analyzed a sample of 30 coastal state plans to determine how well they support mitigation. Findings indicate that although plans scored
moderate to low for all plan quality principles, plan quality has modestly improved over the past decade. In addition, some states scored low
for one principle, which can undermine implementation of otherwise high-scoring plans for the remaining principles. Recommendations are
offered on how plan quality evaluation can be used to guide and monitor state development of hazard mitigation plans. DOI: 10.1061/

Introduction
The role of state planning for mitigation to achieve disaster resiliency has been a subject of interest and contention. The federal
Disaster Mitigation Act (DMA) of 2000 requires states to prepare
plans that are to guide state hazard mitigation activities. This role
involves a variety of choices. States can choose to advance mitigation narrowly by preparing standalone mitigation plans or integrate
mitigation plans with ongoing efforts in land use planning, ecosystem management, economic development, disaster recovery, and
climate change adaptation. Further, the relationship between state
mitigation plans and local mitigation activities, and the interrelationship among other state agency plans, is subject to controversy
and debate (Godschalk et al. 1999). In all cases, state mitigation
plans can serve a critical role in fostering intergovernmental
coordination (Burby and May 1997), enhancing local plan compliance with broader state goals (Deyle and Smith 1998), and ultimately building resiliency of human communities to resist or
absorb and rapidly recover from disaster impacts (Beatley 2009;
Godschalk et al. 2009; Peacock et al. 2008).
If state plans are intended to guide state and local government
behavior to support state and federal interests in hazard mitigation,
then the quality of plans becomes a critical issue. The DMA
strongly encourages all state and local governments to prepare hazard mitigation plans based on a participatory process and technical
vulnerability analysis. DMA-based plans should identify and

prioritize a range of incentives (e.g., funding, technical assistance),
regulatory powers, taxing and spending powers, and infrastructure
investment strategies that state and local governments can apply to
mitigation. Once DMA plans are in place, state (and local) governments become eligible for pre- and postdisaster federal mitigation
funds. However, with the exception of the Godschalk et al. (1999)
pre-DMA study, state mitigation plans have not received attention
by planning and hazard mitigation researchers, and no nationallevel studies have assessed the quality of plans produced under
the DMA.
This study examines the quality of state plans prepared under
DMA. Plans are but one step in a broader process aimed at effectuating change (Berke and Smith 2010). However, without setting
clear and practicable goals for the future and a coordinated strategy
for achieving the goals, the prospects for real change are limited.
Two research questions are examined here: (1) How well do state
mitigation plans prepared under DMA achieve the principles of
plan quality? (2) What are the comparative strengths and weaknesses of individual state plans by plan quality principle?
This paper is organized as follows. First, past efforts at plan
quality conceptualization are reviewed, and a set of principles of
plan quality is derived that provides criteria for evaluating state
mitigation plans. Then key requirements for state mitigation plans
as stipulated by DMA are reviewed. Next, the study methods are
described, and findings from the evaluation of plans are provided.
Finally, conclusions are summarized, recommendations for improving state mitigation plan quality are presented, and guidance
for future research is offered.
Conceptual Foundations: Principles of Plan Quality
Given the potential benefits of mitigation, state plans should be
evaluated to enable examination of the quality of plans, both to
review the effectiveness of past processes and to guide future processes. The literature has begun to yield an agreed-upon set of
principles for assessing the quality of plans. In one of the earliest
empirical evaluations of comprehensive plans, Gruft and Gutstein
(1972) developed a set of criteria based on a set of principles
indicating that plans should be derived from a rational process

in a scientific sense, and a democratic process that included representation of all stakeholders.
Various plan quality studies focused on hazard mitigation began
to appear in the 1980s and 1990s. In the first empirical work
on plans aimed at disaster reduction, sociologists Wenger et al.
(1985) explored the links between disaster plans and public perceptions. Soon, planning scholars started to show steady interest in the
topic. Deyle and Smith (1998) assessed local plan quality and plan
compliance with Florida’s coastal hazards planning mandate, and
Tang et al. (2008) examined plan quality in response to the national
tsunami mitigation program. Berke and French (1994), Burby and
May (1997), and Dalton and Burby (1994) examined the directionsetting function (facts, goals, and policies) of hazard mitigation
elements of plans in six states and addressed data reliability issues
by double coding 139 comprehensive plans and computing intercoder agreement scores. Hopkins (2001) suggested including the
external validity of plans, addressing their relevance in meeting
the needs of local situations. As noted, the Godschalk et al. (1999)
empirical evaluation of plans represents the only study of state
mitigation plan quality.
In an assessment of plan evaluation as embodied in the plan
document, Baer (1997) extended plan quality thought and practice
by developing the most robust set of plan quality principles completed at that time. He developed a composite list of 60 criteria
arranged according to various basic principles including, for example, rational model considerations (problems, goals, policies); procedural validity (who was involved, why they were chosen); scope
that connected to larger geographic scales; implementation; and
communication linked to convincing presentation. More recently,
Norton (2008) observed that a fundamental approach to deriving
principles of plan quality comes from communicative action theory.
Viewed as a communicative policy act, Norton argues that the
plan can be thought of as originating from a rational process that
embraces place-making and democratic discourse. He contends
that the principles of plan quality should reflect certain conditions
that support democratic discourse in that plans must be (1) comprehensible to all as they should be clearly understood, (2) legitimate
in that they reflect the interests of stakeholders affected by the plan,
(3) accurate in a scientific sense and in an emancipatory sense in
that information has been subject to alternative interpretations
and corrections by stakeholders, and (4) sincere in that they include
implementation and monitoring procedures that hold organizations
accountable for carrying out the plan (Forester 1989; Innes 1995;
Innes and Booher 1999).
Since the mid-1990s the empirical base of plan quality evaluation has expanded dramatically. This allowed Berke and
Godschalk (2009) to conduct a meta-analysis that quantitatively
compared plan quality scores. The 16 published studies included
in the meta-analysis covered a range of topics, research designs,
domestic and international settings, and samples. Natural hazard
mitigation was the most frequent topic (seven studies), followed
by smart growth, sustainable development, watershed protection,
housing affordability, landscape ecosystems, coastal resources,
and human rights of indigenous peoples. From the plan quality
studies, Berke and Godschalk proposed a refined approach to plan
quality evaluation that recognizes the core purpose of a highquality plan, which is to “provide a clear and convincing picture
of the future, which strengthens the plan’s influence in the land
planning arena” (2009, p. 229). They maintain that two dimensions
of principles should be included in plan quality evaluation: the
internal plan quality dimension includes principles that guide
the content and format of the key components of a plan, and
the external plan quality dimension offers principles related to how
well the plan fits its local situation to maximize its use fulness and
influence. As will be discussed subsequently, six principles are
important since they are closely aligned with DMA requirements
for preparing state mitigation plans, with principles 1–4 representing the internal dimension and principles 5–6 representing the
external dimension:
1. Goals are future desired conditions that reflect the breadth of
values affected by the plan.
2. The fact base provides the empirical foundation to ensure
that key hazard problems are identified and prioritized and
mitigation policy making is well informed.
3. Policies (or actions) serve as a general guide to decisions about
development and assure that plan goals are achieved.
4. Implementation and monitoring involves the assignment of
organizational responsibilities, timelines, and funds to implement plan. It also involves tracking the extent to which policies
are carried out.
5. Interorganizational coordination entails recognition of the
interdependent actions of state and local organizations that
need coordination for plan implementation.
6. Participation involves recognition of formal and informal
actors engaged in preparing the plan, including other governmental bodies, private-sector institutions, nonprofits, and
individual citizens.
Confidence in the validity of the plan quality principles has
grown as there is an expanding literature that examines the effect
of plan quality principles on the degree of success in plan implementation. While some principles have a greater of an effect than
others (Brody et al. 2006; Deyle et al. 2008), there is an emerging
trend showing that plan quality is influential across the range of
principles. At the local level, studies have found that plan quality
is a powerful driver on local government adoption of land use and
building code regulations that reduce damage from an earthquake
(Nelson and French 2002), integration of stormwater mitigation
techniques in development permits (Berke et al. 2006), adoption
of mitigation tools through increased commitment of local planners
(Dalton and Burby 1994), and the strength of landscape protection
provisions of zoning ordinances (Norton 2008). Less attention is
directed at state plan quality effects on local plans and implementation, but the limited research on state planning indicates that state
plan goals, policies, and implementation efforts have a significant
influence on local plan quality and actions (Burby and May 1997;
Deyle and Smith 1998).
Disaster Mitigation Act and the Role of States
Congress passed the DMA in 2000 in response to rising disaster losses in the United States, a desire to more effectively
and efficiently distribute federal mitigation funds, a growing network of hazard scholars emphasizing the importance of improved
risk-reduction measures, and questions regarding the efficacy of
existing hazard mitigation programs (Mileti 1999; Godschalk et al.
1999, 2009; Burby et al. 1999; Birkland 2006; Smith 2008). The
DMA represents a more proactive approach than the federal legislation predating the DMA, known as the Stafford Act. The primary
difference in the two pieces of federal legislation is the increased
emphasis on the importance of preevent planning at the state and
local levels. While the Stafford Act required state “409 hazard mitigation plans,” such plans were not evaluated on a regular basis by
the Federal Emergency Management Agency (FEMA) plan quality
was not tied to the receipt of postdisaster federal mitigation funds
(Godschalk et al. 1999).
The DMA can be characterized as a reflexive law that emphasizes collaborative solutions and devolution of power from the

federal government to state and local governments (Mazmanian
and Kraft 1999; Nolon 2009). The intent is to build lower level
capacity (funding, training, technical assistance, databases) to
develop and achieve performance-based solutions. Reflexive
laws establish intergovernmental partnerships that encourage the
engagement of stakeholders affected by the outcomes of proposed
solutions, ensure connectivity and communication, and enhance the
resiliency of networks capable of adapting to change. In contrast,
formal regulatory mandates require higher-level governments to
create and impose standards on lower-level governments.
Using the reflexive-law approach, the DMA provides a framework for federal, state, and local cooperation that is a model for
a more comprehensive and integrated approach to hazard mitigation
(Nolon 2009). State and local governments are encouraged to undertake a collaborative process to develop hazard mitigation plans,
and once plans are approved by FEMA—the lead federal agency
charged with implementation of DMA—they become eligible for
pre- and postdisaster funding for mitigation, such as appropriations
under the the Pre-Disaster Mitigation program and the Hazard Mitigation Grant Program (FEMA 2004). States are to coordinate activities related to risk assessment, identification and implementation of
mitigation strategies, and monitoring and evaluation of mitigation
performance by supporting the development of local mitigation plans
and providing technical assistance to local governments.
Thus, state plans are the linchpin for successful mitigation and
long-term disaster resiliency under DMA. Their function is to
establish comprehensive regimes for building cooperation among
state agencies and between state and local government planning
and regulation. Evaluation of the quality of state mitigation plans
reveals whether they offer a strong foundation for proactive policy
guidance to prevent or lessen loss and build resiliency.
Data and Methods
Sample Selection and Data Collection
The sampling unit of the present study is the state hazard mitigation
plan. The sample is based on the 30 coastal states, including the
Great Lakes states. The focus is on coastal states because they
represent diverse geographic locations and have wide variation in
population growth and development rates. Moreover, mitigation
may be an especially important planning issue for coastal states
because coastal areas are especially prone to hazards and tend to
experience higher growth rates than the rest of the country [Beatley
et al. 2002; National Oceanic and Atmospheric Administration
(NOAA) 2004].
State hazard mitigation plans were collected primarily by downloading them from official state websites, typically the emergency
management agency or planning department website. However, a
number of states did not make their plans available online or had
out-of-date plans posted online. These plans were obtained by
submitting e-mail, phone, and mail requests to the state hazard
mitigation officer or other mitigation planning staff. All 30 state
hazard mitigation plans were obtained (Table 1). Each of the plans
was an updated State Hazard Mitigation Plan and compliant with
the DMA 2000. Two of the plans were adopted in 2006, 17 in 2007,
and 11 in 2008.
Coding Instrument
A coding instrument was developed based on a derivation of
coding items to serve as the recording unit for the study's data.
The items were selected to assess how well each of the six plan
quality principles was accounted for in a plan. The principles,
corollary indexes, and items are illustrated in the appendix, and
the coding protocol is available online [Institute for the Environment (2011)]. Multiple rounds of testing the coding instrument
were conducted following standard code development procedures
(Krippendorff 2004). Each item was measured on one of two
scales, a 0 to 1 binary scale or a 0 to 2 ordinal scale. For the binary
items, 0 denoted that the item in question was not included and 1
denoted that the item was present. For the ordinal items, 0 denoted
that the item was not included, 1 denoted that there was a general,
brief description related to the item, and 2 denoted a clear and
detailed narrative description, with lists, table, figures, and maps
where applicable. The items were developed to measure the principles of plan quality and adapted to correspond with the FEMA
plan development guidelines that assist states in development of
state mitigation plans (FEMA 2004). Table 2 indicates how the
sections in the FEMA planning guidelines correspond to the plan
quality principles used in this study.
There are differences in the literature on the use of scales in plan
coding. For example, this study uses a binary scale for goals that is
consistent with the use of this scale by almost all previous studies
that examined plans based on this principle (Berke and Godschalk
2009) with the exception of the Tang et al. (2008) study, which
coded goals (and all other items for all principles) using an ordinal
scale. The fundamental rationale for assignment of scales in the
present study is based on coder interpretations of plan documents.
Some analysts desire scale equivalency for all items because it
eases comparison across items and does not require weighting
of scales, which requires an assumption that weighting achieves
equivalence. The present authors contend that scale equivalence
could lead to a forced requirement for either binary or ordinal scales
for all items that may not meaningfully capture the data. On the one
hand, use of only binary scales is not necessarily meaningful if
coders are able to make fine-grained distinctions through the
use of an ordinal scale. This would significantly reduce the amount
of information in the data when there are items that could be reliably coded based on ordinal scales. On the other hand, the present
authors' counterargument against the use of only an ordinal scale
is that for some items coders may be more prone to guess which
category an item should be placed in because the distinctions
among the categories are not always clear.
Content Analysis Procedures
To increase reliability in evaluation scores, each of the 30 state
hazard mitigation plans was content analyzed by two of four coders
on the coding team who independently coded each plan. Rules
were developed by the coding team to ensure that all coders interpreted the items as consistently as possible. Coder pairings were
systematically varied to ensure that each coder double-coded with
each of the other three coders on multiple plans. This tactic minimized the potential for intercoder dynamics, which could have
reduced reliability. An example of coder dynamics is the deference
of one coder to another during the reconciliation process whereby
the coders reviewed each difference in measurement and rechecked
the plan document to determine which code was accurate. Overall
percentage agreement scores reported in the plan quality literature
ranged between 70 and 97% (Berke and Godschalk 2008). The
present study's overall score of 73%, calculated from the
double-coded data before the reconciliation process, falls within
this range of acceptable scores.
Computation of Plan Quality Scores
Index scores for each of the four internal principles and two
external principles were computed for each plan (see appendix).
Consistent with previous plan quality evaluation studies, an index

Findings on the Quality of State Hazard Mitigation
Plans
First, overall mean scores of plan quality are presented as an indicator of states’ commitment to hazard mitigation. Then mean
scores, standard deviations, and the range from lowest to highest
scores are presented for each of the internal and external principles
of plan quality. Next, the spatial distribution of the plan quality
scores is presented on maps to permit comparison of state plans,
followed by an assessment of how well plans account for hazards
linked to climate change.
Overall Plan Quality Scores
Plans offer limited direction to guide short-term decisions to
achieve long-term mitigation. For each of the four internal plan
quality principles the overall mean score ranged from only 0.97
for goals to 0.60 for policies out of a maximum score of 2 (Table 3),
indicating that none of the internal principles received more than
half the maximum. Plans will also likely have limited influence on
hazard mitigation outcomes. For the two external plan quality principles the overall mean score was only 0.87 for interorganizational
coordination and 0.65 for participation out of a maximum score
of 2 (Table 4), which indicates that none of the external principles
received more than half the maximum. The findings showed that,
overall states do not have well-organized, technically sound, and
thoroughly prepared plans that reflect a strong commitment to
mitigation.
Internal Principles of Plan Quality Scores
As noted, the goals principle had the highest overall mean score
among internal principles, but there was considerable variation
in the extent to which plans included various types of goals
(Table 3). Three indexes are reported under the goals principle.
Plans most strongly focused on goals addressed the reduction of
hazard loss, including, for example, protecting life and property,
minimizing economic impacts, and reducing inequities of impacts
on socially vulnerable population groups (mean ¼ 1:21 on a 0–2
scale). Plans only moderately focused on interorganizational coordination (mean ¼ 1:10) scored very low on advancing a broader
vision tied to resiliency and sustainability (mean ¼ 0:23). These
findings indicate that goals of state plans concentrate most on
interorganizational coordination to understand, seek, and implement mitigation solutions aimed at reducing various types of losses.
Under a broader view, mitigation is not just about reducing loss
but also about achieving gains such as enhancing the resiliency
of human communities to resist, absorb, and bounce back from impacts of natural hazards (Peacock et al. 2008).This would require
promoting economic development, protecting the life support
functions of natural systems upon which human communities
depend, and reducing poverty.
The fact base principle scored moderately low (overall
mean ¼ 0:90). Among the five indexes included in the fact base,
the quality of hazard assessment (e.g., location, magnitude, likelihood of occurrence of each hazard) received the highest score
(mean ¼ 1:44), followed by moderate scores for vulnerability assessments that identify the number of exposed people and property

(mean ¼ 1:17) and risk estimates that integrate the probabilities of
occurrences of hazard events with vulnerabilities to approximate
loss (mean ¼ 1:05). However, systematic prioritization of hazards
based on the level of risk from each hazard only received a moderately low score (mean ¼ 0:73). Insufficient data on hazard priorities reduce the capability to shape mitigation policy and use
funding to maximize reduction of risk. Finally, the assessment
of states’ capability to manage mitigation efforts based on policies,
laws, and funding received a moderately low score (mean ¼ 0:79).
Thus, knowledge about existing management strengths and areas
in which the state needs to strengthen its capabilities is generally
incomplete in state plans.
For mitigation policies it was reasoned that since mitigation of
the multiple impacts of natural hazards is a complex problem, no
single policy tool effectively mitigates the multiple impacts. Rather,
the greater the number of tools and the clearer the explanation of
how they apply to mitigation, the more complete and effective the
mitigation policy. The overall score for mitigation policies was
low (overall mean ¼ 60). This finding is troublesome since a weak
set of policies means that a state is less likely to exert control over
its planning agenda and ensure that long-range statewide interests
supersede short-range local interests, and that plans will not provide
a clear, relevant basis for implementing and monitoring a state plan.
While the policies of plans scored low, there is considerable
variation across policy types. Acquisition of structures and land
in hazardous locations received the highest score (mean ¼ 1:17)
largely due to financial support provided by federal programs
for floodplain buyouts. The two primary programs that offer
federal funds for buyouts of structures in flood-prone areas are
the Pre-Disaster Mitigation program and Hazard Mitigation Grant
Program (FEMA 2004). The next highest scoring policy is promotion of awareness and knowledge (mean ¼ 1:04), which is low cost
and requires little political commitment. A low scoring group of
policies involves more significant commitment and intervention,
including land development regulations aimed at controlling the
type, design, and arrangement of land uses in hazardous areas
(mean ¼ 0:60), adjusting the location and design of public infrastructure (mean ¼ 0:58), financial assistance for mitigation projects (mean ¼ 0:52), and structural controls (e.g., levees and
seawalls) to lessen the effects of hazardous forces (mean ¼ 0:46).
Market incentives (e.g., tax abatements, reduced impact fees, density bonuses) aimed at encouraging private investment away from
hazardous locations received a very low score (mean ¼ 0:22).
Researchers emphasize the importance of integrating mitigation
with disaster recovery (Smith 2010), but this policy received the
lowest score among all policies (mean ¼ 0:11).
The overall mean score for the implementation and monitoring
principle is moderately low (overall mean ¼ 0:85). If plans score
high on policies, for example, but low on implementation and
monitoring, then plans may become paper documents that are
not carried out and lack regular evaluation and updating to improve
their performance. There is limited variation in mean scores across
the three index scores that include evaluating and updating the plan
(mean ¼ 0:80), monitoring implementation (mean ¼ 0:85), and
implementation support involving identification of sources of
funds, staffing, and mediation expertise to enable implementation
(mean ¼ 0:90).
External Principles of Plan Quality Scores
Table 4 indicates that under the external plan quality principles the
interorganization coordination principle received a subpar score
(overall mean ¼ 0:87). Variation among the three types of activities
under interorganization coordination is considerable. Descriptions
of criteria for prioritizing assistance to communities for project
grants were clear and detailed as reflected by the high score
(mean ¼ 1:73). A second set of coordination activities involving
provisions of support for local plan development received a moderately low score (mean ¼ 0:93). While descriptions of the types of
local support were included in most plans, the level of detail varied
by type of assistance. Technical assistance and grants associated
with federal funds were described in detail, but plans only included
vague explanations about guidance, best practices, and training
programs to help local governments conduct analyses, select strategies, and design public engagement programs. Thus state plans
often missed the opportunity to serve as a single-stop reference
for local officials who often desire identification of types, sources,
and steps toward obtaining plan-making assistance. Finally, state
review of local plans received a low score (mean ¼ 0:47). Plans
generally did not provide a clear and detailed description of review
criteria wherein results of a systematic assessment of local plans
could be used to improve local plan quality. Instead, the review
process described in the plans typically consisted of verbal statements indicating that a basic precheck of local plans would be
conducted to avoid rejection by FEMA.
As noted, the overall score for the documentation of the participation process was somewhat low (mean ¼ 0:65). Among the
three indexes under the participation principle, the explanation
of how each component of the plan was analyzed during the updating process scored highest (mean ¼ 1:33). Plans that clearly
identified how fact base, policies, and monitoring and implementation were updated demonstrated how mitigation planners were
learning over time and adapting their plans. The second index,
which aims to explain organizational involvement, received a
low score (mean ¼ 0:64). Plans often did not identify new organizations that became involved in the most recent update process or
why organizations that were involved in prior planning were not

involved in the update. This finding raises concern that plan authors
have not given a clear rationale for any changes in the organizations
involved and their coordination with others. Finally, the range of
techniques described in plans to engage the public received a
low score (mean ¼ 0:53). Typically, plans indicated that only
one public participation technique was used or none at all. The most
common techniques used were the posting of a draft copy of the
plan to a website and soliciting comments and public notice of
official meetings. Neither technique is proactive in reaching out to
stakeholders, especially those disadvantaged groups (e.g., lowwealth, racial and ethnic minorities) often underrepresented in
government decision-making processes.
In sum, our analysis of state mitigation plans reveals that
their overall quality is moderate to low. While unsatisfactory,
these findings suggest that plans show modest gains in improvement over the last decade. A study of 50 state mitigation plans
revealed that entire sections that cover goals, fact base, policies,
implementation, monitoring, and organizational coordination were
absent in many plans (Godschalk et al. 1999, ch. 9). The present
analysis indicates that all 30 coastal state plans covered each of
these sections.
Comparison of State Plan Quality Scores
To permit comparison of plan quality scores for individual states,
scores using standard deviations from the mean were classified and
mapped. Because this study's primary focus is on the degree of
the distribution, high and low plan qualities (PQ) are defined as
those states with PQ scores greater than one standard deviation
from the mean (high PQ ¼ þ1 SD; low PQ ¼ #1SD).
The geographic patterns of scores are illustrated for internal
plan quality principles in Figs. 1(a)–1(d) and external principles
in Figs. 1(d) and 1(e). The distribution of scores across states is
displayed for each principle. For example, for the fact base
principle [Fig. 1(b)], three states (California, Florida, and North
Carolina) have high scores, but four states (Indiana, Massachusetts,
Pennsylvania, and Texas) have low scores. In another example, under
interorganizational coordination with local planning [Fig. 1(f)],
four states (Florida, North Carolina, Texas, and Wisconsin) scored
high, whereas eight states (Alabama, Connecticut, Georgia, Hawaii,
Maine, Massachusetts, New Jersey, and Pennsylvania) had low
scores.
Although it is instructive to see the national pattern for each
principle of plan quality, mapped scores provide insight about
the strengths and weaknesses of individual plans. California has
the strongest mitigation plan, with above average scores on all
principles, while another three states (Delaware, Florida, and
Wisconsin) have above average scores on all but one principle.
Meanwhile three states (Connecticut, Georgia, and Maine) have
below average scores on all principles. In some instances, states
prepared strong plans for all principles but scored below average
for one principle, which could prevent an otherwise strong plan
from being implemented. For example, scores for Wisconsin are
above average for all plan quality principles, except for a below
average score for participation. Wisconsin’s plan includes a sound
set goals, fact base, mitigation strategy, implementation and monitoring program, and interorganizational coordination, but all this
effort may not be fully realized given the low score for participation. Since engagement with the public, interest groups, and other
state-level organizations with a stake in mitigation is critical to
successful plan implementation, it could be that Wisconsin’s
otherwise strong plan may not be fully carried out.
Conclusions: Quality and State Hazard Mitigation
Plans
The results of this study address two research questions. First, how
well do state mitigation plans prepared under DMA achieve the
principles of plan quality? The results indicate that states have
moderate- to low-quality plans for all internal and external principles. Second, what are the comparative strengths and weaknesses
of state plans across the plan quality principles? Only one state
(California) had above average scores for each of the six plan quality principles, three states (Connecticut, Georgia, and Maine) had
uniformly below average scores on all principles, and some states
prepared strong plans but scored below average for one principle,
which could jeopardize successful implementation.
This study's results are partially consistent with the only
previous study on state hazard mitigation plan quality (Godschalk
et al. 1999). In that study, pre-DMA state mitigation plan quality
was shown to be generally low in the 1990s. Weaknesses were
found in the fact base, goals, policies, and provisions for monitoring and implementation. The plan quality indexes were slightly different in this study, which precludes determination of differences in
scores for each plan quality principle. However, as noted, entire
sections for goals, fact base, policies, implementation and monitoring, and interorganizational coordination were often absent in the
pre-DMA plans (Godschalk et al. 1999, but the present study's results indicate that all contemporary DMA plans addressed each of
these plan quality principles.
There are several possible reasons for the range of plan
quality scores across states. The disaster experiences of states vary
widely. In some cases, states experience a number of smaller
events, whereas in other states major disasters are more common.
The degree to which these experiences lead to policy learning is
instructive. Although many states scored low on policy principles,
there were exceptions. For instance, several high-risk states learned
from past events and modified their policies accordingly; Florida,
North Carolina, and California established state-level planning initiatives prior to the passage of the DMA. In other situations, states
may question the value of engaging in a lengthy preevent hazard
mitigation planning exercise, particularly if clear benefits are not
readily available, hence a possible reason for low public participation and interorganizational coordination scores.
Another reason for the range of plan quality scores across states
is that state agencies responsible for emergency management
(which is typically where the state hazard mitigation plan is
housed) view the importance of hazard mitigation differently. In
some cases, hazard mitigation is not seen as a primary mission of
the agency, nor as important as a strong response capability. Not
only can this lead to a weak state mitigation plan, but it may not
be supported by the necessary state-level policies that span other
agencies and departmental responsibilities, including economic
development, coastal management, and environmental protection.
Viewed from a broader external perspective, the legitimacy of state
mitigation planning may suffer as other state agencies tend to view
the work of emergency management agencies narrowly, failing to
recognize the complementary nature of hazard mitigation activities,
environmental preservation, water quality, sustainability, and, more
recently, resiliency and climate change adaptation. This observation
is also reflected in low fact base scores associated with the identification of a state’s ability to manage hazard mitigation efforts
using existing laws, programs, plans, and financial resources that
go well beyond those administered by state emergency management agencies. Conversely, a hazard mitigation plan benefits from
a strong, broad-based risk-reduction-policy milieu that includes
the emergency management agency and the larger network of

state agencies, private-sector organizations, nonprofits, and others.
California is emblematic of a state with a strong hazard mitigation
policy framework, derived in part from a number of major earthquakes that triggered improvements in mitigation policy over time
(Birkland 2006).
Variation in the strength of state plans may also stem from the
presence of a hazard mitigation advocate or a network of actors that
provide collective advocacy. Mitigation advocates provide technical,
political, and collaborative leadership or a combination thereof.
(a)
Technical leadership may involve the development of a strong fact
base that serves to undergird good policy. Political leadership may
involve taking a strong position on the role of land use and hazards
that may face strong opposition from those that stand to benefit from
weak risk-reduction policies and development standards. Collaborative leadership involves the ability to garner support and build multifaceted coalitions that support strong mitigation policies.
We maintain that FEMA standards for approving state mitigation plans may partially explain the low state plan quality scores.

Current standards for plan quality are minimal. Under these standards, state (and local) governments gain approval of plans and
become eligible for pre- and postdisaster mitigation funds. For
example, eligibility to receive appropriations from the largest
source of postdisaster federal assistance, the Public Assistance
Program (used to fund debris removal and the repair of damaged
infrastructure, often to those states vulnerable preevent conditions),
requires an approved plan based on the minimal standards.
Implications for Policy and Future Research
This study provides a comprehensive set of plan quality principles
(see appendix) that the authors recommend states use to guide the
development of hazard mitigation plans. Application of the principles allows for empirical documentation of patterns of gaps in
current plans, identification of specific weak points that could
undermine the effectiveness of individual plans, and insights on
how these plans can be improved. By understanding the areas
in which these plans are deficient, states can be more effective
in the establishment of a cooperative and proactive policy framework aimed at achieving disaster resiliency.
By following these principles, state hazard mitigation plans can
be more effectively reviewed as part of FEMA’s 3-year plan update
cycle for state mitigation plans and following disasters. Applying
the principles also allows for comparative analysis across states
during the higher-level external review conducted by FEMA.
The findings can provide FEMA with tangible measures to make
targeted improvements in enabling administrative rules that guide
plan making and federal legislation.
As with all research, there are questions left unanswered by
this study. The prominent issue of whether plan quality scores help
lead to successful implementation and better outcomes should be
examined. Researchers and practitioners have long questioned the
value of plans when the issues raised by plans are not acted on.
Three basic questions will guide future research on state mitigation
plan implementation: (1) How successfully are the hazard issues
raised by state plans integrated into local jurisdiction mitigation
plans? (2) Does the quality of state plans affect state agencies’ commitment to hazard mitigation? (3) How influential are the local
building practices used by state agencies, and what is the effect
of these practices on bringing about local plans and actions focused
on these issues?
In sum, the authors maintain that plan quality evaluation is
emerging as a valuable tool for systematic analysis of plans.
The concepts and methods presented in this paper offer an objective
and straightforward approach to studying plan quality and guiding
plan preparation. While implementation of plans is a critical next
step for exploration, the issue of plan quality should come first.
Without good plans, implementation could merely become an
act of carrying out empty policy promises.
