Kendall County Multi-Hazard Mitigation Plan February 14, 2011
Section 1 - Public Planning Process
1.1 Narrative Description
Hazard mitigation is defined as any sustained action to reduce or eliminate long-term risk to
human life and property from hazards. The Federal Emergency Management Agency (FEMA)
has made reducing hazards one of its primary goals; hazard mitigation planning and the
subsequent implementation of resulting projects, measures, and policies is a primary mechanism
in achieving FEMA's goal.
The Multi-Hazard Mitigation Plan (MHMP) is a requirement of the Federal Disaster Mitigation
Act of 2000 (DMA 2000). The development of a local government plan is required in order to
maintain eligibility for certain federal disaster assistance and hazard mitigation funding
programs. In order for the National Flood Insurance Program (NFIP) communities to be eligible
for future mitigation funds,they must adopt an MHMP.
In recognition of the importance of planning in mitigation activities, FEMA created Hazards
USA Multi-Hazard (HAZUS-MH), a powerful geographic information system (GIS)-based
disaster risk assessment tool. This tool enables communities of all sizes to predict estimated
losses from floods, hurricanes, earthquakes, and other related phenomena and to measure the
impact of various mitigation practices that might help reduce those losses. The Illinois
Emergency Management Agency (IEMA) has determined that HAZUS-MB should play a
critical role in Illinois's risk assessments. Southern Illinois University, Carbondale (SIUC) and
the Polis Center (Polis) at Indiana University Purdue University Indianapolis (IUPUI) are
assisting Kendall County planning staff with performing the hazard risk assessment.
1.2 Planning Team Information
The Kendall County Multi-Hazard Mitigation Planning Team is headed by Terry Tichava, who is
the primary point of contact. Members of the planning team include representatives from various
county departments, cities and towns, and public and private utilities. Table 1-1 identifies the
planning team individuals and the organizations they represent. In December 2010, Terry
Tichava retired and EMA Coordinator Joseph T. Gillespie replaced him.

Communications
The Disaster Mitigation Act (DMA) planning regulations stress that planning team members
must be active participants. The Kendall County MHMP committee members were actively
involved on the following components:
• Attending the MHMP meetings
• Providing available GIS data and historical hazard information
• Reviewing and providing comments on the draft plans
• Coordinating and participating in the public input process
• Coordinating the formal adoption of the plan by the county
An MHMP kickoff meeting was held at the Kendall County Sheriffs Office on March 10, 2010.
Representatives from Southern Illinois University explained the rationale behind the MHMP
program and answered questions from the participants. The SIUC also provided an overview of
HAZUS-MH, described the timeline and the process of the mitigation planning project, and
presented Kendall County with a Memorandum of Understanding (MOU) for sharing data and
information.
The Kendall County Multi-Hazard Mitigation Planning Committee met on March 10, 2010,
April 14, 2010, June 9, 2010, August 11, 2010 and October 13, 2010. Each meeting was
approximately two hours in length. The meeting minutes are included in Appendix A. During
these meetings, the planning team successfully identified critical facilities, reviewed hazard data
and maps, identified and assessed the effectiveness of existing mitigation measures, established
mitigation projects, and assisted with preparation of the public participation information.
1.3 Public Involvement in Planning Process
An effort was made to solicit public input during the planning process, and a public meeting was
held on June 9, 2010 to review the county's risk assessment. Appendix A contains the minutes
from the public meeting. Appendix B contains articles published by the local newspaper
throughout the public input process.

3.1 Topography
Kendall County is situated in the Central Lowland Province of the Till Plains Section. The
northwestern part of the county is within the Bloomington Ridged Plain physiographic division,
and the southeastern part of the county is within the Kankakee Plain physiographic division. The
Bloomington Ridged Plain includes most of the Wisconsin Moraines, which are characterized by
low, broad concentric ridges with intervening wide stretches of relatively flat or gently
Kendall County Multi-Hazard Mitigation Plan Page 10 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
undulating ground moraine. The Kankakee Plain is a level to gently rolling plain. The origin of
this physiographic division is believed to be fluviolacustrine. The landforms commonly found on
in this division include low moraine islands, glacial terraces, bars, and dunes. Figure 3-2 shows

Kendall County Multi-Hazard Mitigation Plan February 14, 2011
Kendall County is one of the fasting developing counties in the United States. The County and
nearly all of incorporated communities (Oswego, Plano, Minooka, Montgomery, Plainfield,
Sandwich, and Yorkville) have either a comprehensive or a future land use plan (see Table 1-4).
The purpose of these plans is to provide guidance for future development. Each plan calls for no
development in floodplains and carefully considers placement of residential space in relation to
industrial and commercial land uses. Figures 3-5 through 3-12 shows the planned land use in
each these jurisdictions.

Section 4 - Risk Assessment
The goal of mitigation is to reduce the future impacts of a hazard including loss of life, property
damage, disruption to local and regional economies, and the expenditure of public and private
funds for recovery. Sound mitigation must be based on sound risk assessment. A risk assessment
involves quantifying the potential loss resulting from a disaster by assessing the vulnerability of
buildings, infrastructure, and people. This assessment identifies the characteristics and potential
consequences of a disaster, how much of the community could be affected by a disaster, and the
impact on community assets. A risk assessment consists of three components—hazard
identification, vulnerability analysis, and risk analysis.
4.1 Hazard Identification/Profile
4.1.1 Existing Plans
The plans identified in Table 1-3 did not contain a risk analysis. These local planning documents
were reviewed to identify historical hazards and help identify risk. To facilitate the planning
process, flood data for the Federal and State Government were used for the flood analysis.
4.1.2 National Hazard Records
4.1.2.1 National Climatic Data Center (NCDC) Records
To assist the planning team, historical storm event data was compiled from the National Climatic
Data Center (NCDC). NCDC records are estimates of damage reported to the National Weather
Service from various local, state, and federal sources. However, these estimates are often
preliminary in nature and may not match the final assessment of economic and property losses
related to given weather events.
The NCDC data included 202 reported events in Kendall County between May 27, 1954 and the
October 31, 2009 (the most updated information as of the date of this plan). A summary table of
events related to each hazard type is included in the hazard profile sections that follow. A full
table listing all events, including additional details, is included as Appendix D. In addition to
NCDC data, Storm Prediction Center (SPC) data associated with tornadoes, strong winds, and
hail were plotted using SPC recorded latitude and longitude. These events are plotted and
included as Appendix E. The list of NCDC hazards is included in Table 4-1.

4.1.2.2 FEMA Disaster Information
Since 1965 there have been 55 Federal Disaster Declarations for the state of Illinois. Emergency
declarations allow states access to FEMA funds for Public Assistance (PA); disaster declarations
allow for even more PA funding including Individual Assistance (IA) and the Hazard Mitigation
Grant Program (HMGP). Kendall County has received federal aid for both PA and IA funding
for seven declared disasters since 1965. Figure 4-1 depicts the disasters and emergencies that
have been declared for Kendall County since 1965. Table 4-2 lists more specific information for
each declaration that has occurred since 1965.

4.1.3 Hazard Ranking Methodology
Based on planning team input, national datasets, and existing plans, Table 4-3 lists the hazards
Kendall County will address in this multi-hazard mitigation plan. In addition, these hazards
ranked the highest based on the Risk Priority Index discussed in section 4.1.4.

4.1.4 Calculating the Risk Priority Index
The first step in determining the Risk Priority Index (RPI) was to have the planning team
members generate a list of hazards which have befallen or could potentially befall their
community. Next, the planning team members were asked to assign a likelihood rating based on
the criteria and methods described in the following table. Table 4-4 displays the probability of
the future occurrence ranking. This ranking was based upon previous history and the definition
of hazard. Using the definitions given, the likelihood of future events is "Quantified" which
results in the classification within one of the four "Ranges" of likelihood.
Kendall County Multi-Hazard Mitigation Plan Page 27 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
Table 4-4: Future Occurrence Ranking
Probability Characteristics
Event is probable within the calendar year.
4-Highly Likely Event has up to 1 in 1 year chance of occurring.(1/1=100%)
History of events is greater than 33%likely per year.
Event is probable within the next three years.
3-Likely Event has up to 1 in 3 years chance of occurring.(1/3=33%)
History of events is greater than 20%but less than or equal to 33%likely per year.
Event is probable within the next five years.
2-Possible Event has up to 1 in 5 years chance of occurring.(1/5=20%)
History of events is greater than 10%but less than or equal to 20%likely per year.
Event is possible within the next ten years.
1 -Unlikely Event has up to 1 in 10 years chance of occurring.(1/10=10%)
History of events is less than or equal to 10%likely per year.
Next, planning team members were asked to consider the potential magnitude/severity of the
hazard according to the severity associated with past events of the hazard. Table 4-5 gives four
classifications of magnitude/severity.
Table 4-5: Hazard Magnitude
Magnitude/Severity Characteristics
Multiple deaths.
8-Catastrophic Complete shutdown of facilities for 30 or more days.
More than 50%of property is severely damaged.
Injuries and/or illnesses result in permanent disability.
4-Critical Complete shutdown of critical facilities for at least 14 days.
More than 25%of property is severely damaged.
Injuries and/or illnesses do not result in permanent disability.
2-Limited Complete shutdown of critical facilities for more than seven days.
More than 10%of property is severely damaged.
Injuries and/or illnesses are treatable with first aid.
1 -Negligible Minor quality of life lost.
Shutdown of critical facilities and services for 24 hours or less.
Less than 10%of property is severely damaged.
Finally, the RPI was calculated by multiplying the probability by the magnitude/severity of the
hazard. Using these values, the planning team member where then asked to rank the hazards.
Table 4-6 identifies the RPI and ranking for each hazard facing Kendall County.

4.1.5 Jurisdictional Hazard Ranking
Because the jurisdictions in Kendall County differ in their susceptibilities to certain hazards—for
example, The United City of Yorkville which is located on the Fox River floodplain is more
likely to experience significant flooding than Lisbon or Joliet which are located on the uplands
outside of any large stream's or river's floodplain which could potentially cause significant
flooding—the hazards identified by the planning team were ranked by SIUC for each individual
jurisdiction using the methodology outlined in Section 4.1.4. The SIUC rankings were based on
input from the planning team members, available historical data, and the hazard modeling results
described within this hazard mitigation plan. During the five-year review of the plan this table
will be updated by the planning team to ensure these jurisdictional rankings accurately reflect
each community's assessment of these hazards. Table 4-7 lists the jurisdictions and their
respective hazard rankings (Ranking 1 being the highest concern).

4.1.6 GIS and HAZUS-MH
The third step in this assessment is the risk analysis, which quantifies the risk to the population,
infrastructure, and economy of the community. Where possible, the hazards were quantified
using GIS analyses and HAZUS-MH. This process reflects a Level 2 approach to analyzing
hazards as defined for HAZUS-MH. The approach includes substitution of selected default data
with local data. This process improved the accuracy of the model predictions.
HAZUS-MH generates a combination of site-specific and aggregated loss estimates depending
upon the analysis options that are selected and the input that is provided by the user. Aggregate
inventory loss estimates, which include building stock analysis, are based upon the assumption
that building stock is evenly distributed across census blocks/tracts. Therefore, it is possible that
overestimates of damage will occur in some areas while underestimates will occur in other areas.
With this in mind, total losses tend to be more reliable over larger geographic areas than for
individual census blocks/tracts. It is important to note that HAZUS-MH is not intended to be a
substitute for detailed engineering studies. Rather, it is intended to serve as a planning aid for
communities interested in assessing their risk to flood-, earthquake-, and hurricane-related
hazards. This documentation does not provide full details on the processes and procedures
completed in the development of this project. It is only intended to highlight the major steps that
were followed during the project.
Site-specific analysis is based upon loss estimations for individual structures. For flooding,
analysis of site-specific structures takes into account the depth of water in relation to the
structure. HAZUS-MH also takes into account the actual dollar exposure to the structure for the
costs of building reconstruction, content, and inventory. However, damages are based upon the
assumption that each structure will fall into a structural class, and structures in each class will
respond in a similar fashion to a specific depth of flooding or ground shaking. Site-specific
analysis is also based upon a point location rather than a polygon, therefore the model does not
account for the percentage of a building that is inundated. These assumptions suggest that the
loss estimates for site-specific structures as well as for aggregate structural losses need to be
viewed as approximations of losses that are subject to considerable variability rather than as
exact engineering estimates of losses to individual structures.
The following events were analyzed. The parameters for these scenarios were created through
GIS, HAZUS-MH, and historical information to predict which communities would be at risk.

4.2 Vulnerability Assessment
4.2.1 Asset Inventory
4.2.1.1 Processes and Sources for Identifying Assets
The HAZUS-MH data is based on best available national data sources. The initial step involved
updating the default HAZUS-MH data using State of Illinois data sources. At Meeting #1, the
planning team members were provided with a plot and report of all HAZUS-MH critical
facilities. The planning team took GIS data provided by SIUC-Polis; verified the datasets using
local knowledge, and allowed SIUC-Polis to use their local GIS data for additional verification.
SIUC GIS analysts made these updates and corrections to the HAZUS-MH data tables prior to
performing the risk assessment. These changes to the HAZUS-MH inventory reflect a Level 2
analysis. This update process improved the accuracy of the model predictions.
The default HAZUS-MH data has been updated as follows:
• The HAZUS-MH defaults, critical facilities, and essential facilities have been updated
based on the most recent available data sources. Critical and essential point facilities have
been reviewed, revised, and approved by local subject matter experts at each county.
• The essential facility updates (schools, medical care facilities, fire stations, police
stations, and EOCs) have been applied to the HAZUS-MH model data. HAZUS-MH
reports of essential facility losses reflect updated data.
Kendall County provided SIUC with parcel boundaries and county Assessor records. Records
without improvements were deleted. The parcel boundaries were converted to parcel points
located in the centroids of each parcel boundary. Each parcel point was linked to an Assessor
record based upon matching parcel numbers. The generated building inventory points represent
the approximate locations (within a parcel) of building exposure. The parcel points were
aggregated by census block.
• The aggregate building inventory tables used in this analysis have not been updated.
Default HAZUS-MH model data was used for the earthquake.
• For the flood analysis, user-defined facilities were updated from the building inventory
information provided by Kendall County.
Kendall County Multi-Hazard Mitigation Plan Page 31 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
Parcel-matching results for Kendall County are listed in Table 4-8.
Table 4-8: Parcel-Matching for Kendall County
Data Source Count
Assessor Records 53,498
County-Provided Parcels 53,498
Assessor Records with Improvements 40,234
Matched Parcel Points 40,234
The following assumptions were made during the analysis:
• The building exposure for flooding, tornado, and HAZMAT is determined from the
Assessor records. It is assumed that the population and the buildings are located at the
centroid of the parcel.
• The building exposure for earthquake used HAZUS-MH default data.
• The algorithm used to match county-provided parcel point locations with the Assessor
records is not perfect. The results in this analysis reflect matched parcel records only. The
parcel-matching results for Kendall County are included in Table 4-8.
• Population counts are based upon 2.5 persons per household. Only residential occupancy
classes are used to determine the impact on the local population. If the event were to
occur at night, it would be assumed that people are at home (not school, work, or church).
• The analysis is restricted to the county boundaries. Events that occur near the county
boundaries do not contain damage assessments from adjacent counties.
4.2.1.2 Essential Facilities List
Table 4-9 identifies the essential facilities that were added or updated for the analysis. Essential
facilities are a subset of critical facilities. A map and list of all critical facilities is included as

4.3 Future Development
As the county's population continues to grow, the residential and urban areas will extend further
into the county, placing more pressure on existing transportation and utility infrastructure while
increasing the rate of farmland conversion; Kendall County will address specific mitigation
strategies in Section 5 to alleviate such issues.
Because Kendall County is vulnerable to a variety of natural and technological threats, the
county government—in partnership with state government—must make a commitment to
prepare for the management of these types of events. Kendall County is committed to ensuring
that county elected and appointed officials become informed leaders regarding community
hazards so that they are better prepared to set and direct policies for emergency management and
county response.

4.4 Hazard Profiles
4.4.1 Tornado Hazard
Hazard Definition for Tornado Hazard
Tornadoes pose a great risk to Illinois and its citizens. Tornadoes can occur at any time during
the day or night. They can also happen during any month of the year. The unpredictability of
tornadoes makes them one of the state's most dangerous hazards. Their extreme winds are
violently destructive when they touch down in the region's developed and populated areas.
Current estimates place the maximum velocity at about 300 miles per hour, but higher and lower
values can occur. A wind velocity of 200 miles per hour will result in a wind pressure of 102.4
pounds per square foot of surface area—a load that exceeds the tolerance limits of most
buildings. Considering these factors, it is easy to understand why tornadoes can be so devastating
for the communities they hit.
Tornadoes are defined as violently-rotating columns of air extending from thunderstorms to the
ground. Funnel clouds are rotating columns of air not in contact with the ground; however, the
violently-rotating column of air can reach the ground very quickly and become a tornado. If the
funnel cloud picks up and blows debris, it has reached the ground and is a tornado.
Tornadoes are classified according to the Fujita tornado intensity scale. The tornado scale ranges
from low intensity FO with effective wind speeds of 40 to 70 miles per hour to F5 tornadoes with
effective wind speeds of over 260 miles per hour. The Fujita intensity scale is described in Table
4-11.

Previous Occurrences for Tornado Hazard
There have been several occurrences of tornadoes within Kendall County during the past few
decades. The NCDC database reported 14 tornadoes/funnel clouds in Kendall County since
1954. The most recent recorded event occurred on July 27, 2003, during a chain of
thunderstorms. The tornado touched down near the Hideaway Lake Camp near Yorkville,
Illinois.

* NCDC records are estimates of damage compiled by the National Weather Service from various local, state, and federal
sources. However, these estimates are often preliminary in nature and may not match the final assessment of economic and
property losses related to a given weather event.
Geographic Location for Tornado Hazard
The entire county has the same risk for occurrence of tornadoes. They can occur at any location
within the county.
Hazard Extent for Tornado Hazard
The historical tornadoes generally moved from southwest to northeast across the county. The
extent of the hazard varies both in terms of the extent of the path and the wind speed.
Kendall County Multi-Hazard Mitigation Plan Page 35 of 174
Kendall County Multi-Hazard Mitigation Plan February 14,2011
Risk Identification for Tornado Hazard
Based on historical information, the occurrence of future tornadoes in Kendall County is likely.
Tornadoes with varying magnitudes are expected to happen. According to the RPI, tornadoes
ranked as the number two hazard.
RPI=Probability x Magnitude/Severity.
Probability x Magnitude = RPI
/Severity
3 x 2 = 6
Vulnerability Analysis for Tornado Hazard
Tornadoes can occur within any area in the county; therefore, the entire county population and
all buildings are vulnerable to tornadoes. To accommodate this risk, this plan will consider all
buildings located within the county as vulnerable. The existing buildings and infrastructure in.
Kendall County are discussed in Table 4-10.
Critical Facilities
All critical facilities are vulnerable to tornadoes. A critical facility will encounter many of the
same impacts as any other building within the jurisdiction. These impacts will vary based on the
magnitude of the tornado but can include structural failure, damaging debris (trees or limbs),
roofs blown off or windows broken by hail or high winds, and loss of facility functionality(e.g. a
damaged police station will no longer be able to serve the community). Table 4-9 lists the types
and numbers of all of the essential facilities in the area. A map and list of all critical facilities is
included as Appendix F.
Building Inventory
The building exposure in terms of types and numbers of buildings for the entire county is listed
in Table 4-10. The buildings within the county can all expect the same impacts, similar to those
discussed for critical facilities. These impacts include structural failure, damaging debris(trees or
limbs), roofs blown off or windows broken by hail or high winds, and loss of building function
(e.g. damaged home will no longer be habitable causing residents to seek shelter).
Infrastructure
During a tornado the types of infrastructure that could be impacted include roadways, utility
lines/pipes, railroads, and bridges. Since the county's entire infrastructure is equally vulnerable,
it is important to emphasize that any number of these items could become damaged during a
tornado. The impacts to these items include broken, failed, or impassable roadways, broken or
failed utility lines (e.g. loss of power or gas to community), and railway failure from broken or
impassable railways. Bridges could fail or become impassable causing risk to traffic.
An example scenario is described as follows to gauge the anticipated impacts of tornadoes in the
county, in terms of numbers and types of buildings and infrastructure.

GIS overlay modeling was used to determine the potential impacts of an F4 tornado. The
analysis used a hypothetical path based upon the F4 tornado event that ran for 18 miles
southwest to northeast across the County impact portions of The United City of Yorkville and
the Village of Oswego. The selected widths were modeled after a recreation of the Fujita-Scale
guidelines based on conceptual wind speeds,path widths, and path lengths. There is no guarantee
that every tornado will fit exactly into one of these six categories. Table 4-13 depicts tornado
damage curves as well as path widths.
Table 4-13: Tornado Path Widths and Damage Curves
Fujita Scale Path Width(feet) Maximum Expected Damage
5 2,400 100%
4 1,800 100%
3 1,200 80%
2 600 50%
1 300 10%
0 150 0%
Within any given tornado path there are degrees of damage. The most intense damage occurs
within the center of the damage path with decreasing amounts of damage away from the center.
After the hypothetical path is digitized on a map the process is modeled in GIS by adding buffers
(damage zones) around the tornado path. Figure 4-2 and Table 4-14 describe the zone analysis.
The selected hypothetical tornado path is depicted in Figure 4-3, and the damage curve buffers
are shown in Figure 4-4.

An F4 tornado has four damage zones, depicted in Table 4-10. Total devastation is estimated

The results of the analysis are depicted in Tables 4-15 and 4-16. The GIS analysis estimates that
1,560 buildings will be damaged. The estimated building losses were $140.4 million. The
building losses are an estimate of building replacement costs multiplied by the percentages of
damage. The overlay was performed against parcels provided by Kendall County that were
joined with Assessor records showing property improvement.
The Assessor records often do not distinguish parcels by occupancy class if the parcels are not
taxable. For purposes of analysis, the total number of buildings and the building replacement
costs for government,religious/non-profit, and education should be lumped together.

vulnerability to Future Assets/Infrastructure for Tornado Hazard
The entire population and buildings have been identified as at risk because tornadoes can occur
anywhere within the state, at any time of the day, and during any month of the year.
Furthermore, any future development in terms of new construction within the county will be at
risk. The building exposure for Kendall County is included in Table 4-10.
All critical facilities in the county and communities within the county are at risk. A map and list
of all critical facilities is included as Appendix F.
Analysis of Community Development Trends
Preparing for severe storms will be enhanced if officials sponsor a wide range of programs and
initiatives to address the overall safety of county residents. New structures need to be built with
more sturdy construction, and those structures already in place need to be hardened to lessen the
potential impacts of severe weather. Community warning sirens to provide warnings of
approaching storms are also vital to preventing the loss of property and ensuring the safety of
Kendall County residents.

4.4.2 Flood Hazard
Hazard Definition for Flooding
Flooding is a significant natural hazard throughout the United States. The type, magnitude, and
severity of flooding are functions of the amount and distribution of precipitation over a given
area, the rate at which precipitation infiltrates the ground, the geometry and hydrology of the
catchment, and flow dynamics and conditions in and along the river channel. Floods can be
classified as one of two types: upstream floods or downstream floods. Both types of floods are
common in Illinois.
Upstream floods, also called flash floods, occur in the upper parts of drainage basins and are
generally characterized by periods of intense rainfall over a short duration. These floods arise
with very little warning and often result in locally intense damage, and sometimes loss of life,
due to the high energy of the flowing water. Flood waters can snap trees, topple buildings, and
easily move large boulders or other structures. Six inches of rushing water can upend a person;
another 18 inches might carry off a car. Generally, upstream floods cause damage over relatively
localized areas, but they can be quite severe in the local areas in which they occur. Urban
flooding is a type of upstream flood. Urban flooding involves the overflow of storm drain
systems and can be the result of inadequate drainage combined with heavy rainfall or rapid
snowmelt. Upstream or flash floods can occur at any time of the year in Illinois, but they are
most common in the spring and summer months.
Downstream floods, sometimes called riverine floods, refer to floods on large rivers at locations
with large upstream catchments. Downstream floods are typically associated with precipitation
events that are of relatively long duration and occur over large areas. Flooding on small tributary
streams may be limited, but the contribution of increased runoff may result in a large flood
downstream. The lag time between precipitation and time of the flood peak is much longer for
downstream floods than for upstream floods, generally providing ample warning for people to
move to safe locations and, to some extent, secure some property against damage. Riverine
flooding on the large rivers of Illinois generally occurs during either the spring or summer.
Hazard Definition for Dam and Levee Failure
Dams are structures that retain or detain water behind a large barrier. When full or partially full,
the difference in elevation between the water above the dam and below creates large amounts of
potential energy, creating the potential for failure. The same potential exists for levees when they
serve their purpose, which is to confine flood waters within the channel area of a river and
exclude that water from land or communities land-ward of the levee. Dams and levees can fail
due to either 1) water heights or flows above the capacity for which the structure was designed;
or 2) deficiencies in the structure such that it cannot hold back the potential energy of the water.
If a dam or levee fails, issues of primary concern include loss of human life/injury, downstream
property damage, lifeline disruption (of concern would be transportation routes and utility lines
required to maintain or protect life), and environmental damage.
Many communities view both dams and levees as permanent and infinitely safe structures. This
sense of security may well be false, leading to significantly increased risks. Both downstream of
dams and on floodplains protected by levees, security leads to new construction, added
Kendall County Multi-Hazard Mitigation Plan Page 42 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
infrastructure, and increased population over time. Levees in particular are built to hold back
flood waters only up to some maximum level, often the 100-year (1% annual probability) flood
event. When that maximum is exceeded by more than the design safety margin, the levee will be
overtopped or otherwise fail, inundating communities in the land previously protected by that
levee. It has been suggested that climate change, land-use shifts, and some forms of river
engineering may be increasing the magnitude of large floods and the frequency of levee failure
situations.
In addition to failure that results from extreme floods above the design capacity, levees and dams
can fail due to structural deficiencies. Both dams and levees require constant monitoring and
regular maintenance to assure their integrity. Many structures across the U.S. have been under-
funded or otherwise neglected, leading to an eventual day of reckoning in the form either of
realization that the structure is unsafe or, sometimes, an actual failure. The threat of dam or levee
failure may require substantial commitment of time, personnel, and resources. Since dams and
levees deteriorate with age, minor issues become larger compounding problems, and the risk of
failure increases.
Previous Occurrences for Flooding
The NCDC database reported 17 flood events in Kendall County since 1996. One of the most
recent significant events occurred during September 2008. The remnants of hurricane Ike moved
across northern Illinois producing the second round of heavy rain in a 24 hour period. The heavy
rain amounted to 6 to 11 inches across northern Illinois caused extensive and widespread
flooding. Total property damage from this event was estimated at $2 million.
Kendall County NCDC recorded floods are identified in Table 4-18. Additional details for
NCDC events are included in Appendix D.

* NCDC records are estimates of damage compiled by the National Weather Service from various local, state, and federal
sources. However, these estimates are often preliminary in nature and may not match the final assessment of economic and
property losses related to a given weather event.
Previous Occurrences for Dam and Levee Failure
According to the Kendall County planning team, there are no records or local knowledge of any
dam or certified levee failure in the county.
Repetitive Loss Properties
FEMA defines a repetitive loss structure as a structure covered by a contract of flood insurance
issued under the NFIP, which has suffered flood loss damage on two occasions during a 10-year
period that ends on the date of the second loss, in which the cost to repair the flood damage is
25% of the market value of the structure at the time of each flood loss.
The Illinois Emergency Management Agency(IEMA) was contacted to determine the location of
repetitive loss structures. Table 4-19 lists 2009 data for damages to these repetitive loss
structures.

Geographic Location for Flooding
Most river flooding occurs in early spring and is the result of excessive rainfall and/or the
combination of rainfall and snowmelt. Severe thunderstorms may cause flooding during the
summer or fall, but tend to be localized. The primary source of river flooding in Kendall County
is the Wabash River.
Flash floods, brief heavy flows in small streams or normally dry creek beds, also occur within
the county. Flash flooding is typically characterized by high-velocity water, often carrying large
amounts of debris. Urban flooding involves the overflow of storm drain systems and is typically
the result of inadequate drainage following heavy rainfall or rapid snowmelt.
DFIRM was used to identify specific stream reaches for analysis. The areas of riverine flooding
are depicted on the map in Appendix E.
The National Oceanic and Atmospheric Administration (NOAA) Advanced Hydrologic
Prediction Service provides information from gauge locations at points along various rivers
Kendall County Multi-Hazard Mitigation Plan Page 44 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
across the United States. For Kendall County, one gage is located on the Fox River at
Montgomery. Historic flood levels for this gage are provided in Appendix F.
Geographic Location for Dam and Levee Failure
HAZUS-MH identified three dams in Kendall County. The maps in Appendix F illustrate the
locations of Kendall County dams. All three of these dams are low hazard dams (L) and they do
not have an Emergency Action Plan(EAP). Table 4-20 summarizes the dam information.
Table 4-20: National Inventory of Dams
Dam Name River Hazard EAP
Milhurst Lake Dam Tributary to the Fox River L No
Yorkville Dam Fox River L No
Black Berry Creek Dam Black Berry Creek L No
A review of the United States Army Corps of Engineers and local records revealed no certified
levees within Kendall County.
* The dams and levees listed in this multi-hazard mitigation plan are recorded from default HAZUS-MH data. Their physical
presences were not confirmed;therefore,new or unrecorded structures may exist.A more complete list of locations is included in
Appendix F.
Hazard Extent for Flooding
The HAZUS-MH flood model is designed to generate a flood depth grid and flood boundary
polygon by deriving hydrologic and hydraulic information based on user-provided elevation data
or by incorporating selected output from other flood models. HAZUS-MH also has the ability to
clip a Digital Elevation Model (DEM)with a user-provided flood boundary, thus creating a flood
depth grid. For Kendall County, HAZUS-MH was used to extract flood depth by clipping the
DEM with the DFIRMs Base Flood Elevation (BFE) boundary. The BFE is defined as the area
that has a 1% chance of flooding in any given year. Planning team input and a review of
historical information provided additional information on specific flood events.
Hazard Extent for Dam and Levee Failure
When dams are assigned the low (L) hazard potential classification, it means that failure or
incorrect operation of the dam will result in no human life losses and no economic or
environmental losses. Losses are principally limited to the owner's property. Dams assigned the
significant (S)hazard classification are those dams in which failure or incorrect operation results
in no probable loss of human life; however it can cause economic loss, environment damage, and
disruption of lifeline facilities. Dams classified as significant hazard potential dams are often
located in predominantly rural or agricultural areas, but could be located in populated areas with
a significant amount of infrastructure. Dams assigned the high (H) hazard potential classification
are those dams in which failure or incorrect operation has the highest risk to cause loss of human
life and significant damage to buildings and infrastructure.
Kendall County Multi-Hazard Mitigation Plan Page 45 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
According to default HAZUS-MH data, the three dams in Kendall County are low hazard and do
not have Emergency Action Plans (EAP). An EAP is not required by the State of Illinois but is
strongly recommended by the Illinois Department of Natural Resources.
Accurate mapping of the risks of flooding behind levees depends on knowing the condition and
level of protection the levees actually provide. FEMA and the U.S. Army Corps of Engineers are
working together to make sure that flood hazard maps clearly reflect the flood protection
capabilities of levees, and that the maps accurately represent the flood risks posed to areas
situated behind them. Levee owners—usually states, communities, or in some cases private
individuals or organizations—are responsible for ensuring that the levees they own are
maintained according to their design. In order to be considered creditable flood protection
structures on FEMA's flood maps, levee owners must provide documentation to prove the levee
meets design, operation, and maintenance standards for protection against the one-percent-annual
chance flood.
Risk Identification for Flood Hazard
Based on historical information and the HAZUS-MH flooding analysis results, future occurrence
of flooding in Kendall County is highly likely. According to the Risk Priority Index (RPI),
flooding is ranked as the number four hazard.
RPI=Probability x Magnitude/Severity.
Probability x Magnitude = RPI
(Severity
4 x 1 = 4
Risk Identification for Dam/Levee Failure
Based on operation and maintenance requirements and local knowledge of the dams in Kendall
County, the occurrence of a dam or levee failure is unlikely. However, if a high hazard dam were
to fail, the magnitude and severity of the damage could be great. The warning time and duration
of the dam failure event would be very short. Based on input from the planning team, the risk of
dam and levee failure is insignificant, and dam and levee failure was not ranked as a risk.
HAZUS-MH Analysis Using 100-Year Flood Boundary and County Parcels
HAZUS-MH generated the flood depth grid for a 100-year return period by clipping the USGS
1/3 Arc-second (approximately 10-meter raster cell size) Digital Elevation Model (DEM) to the
Kendall County flood boundary. Next, HAZUS-MH utilized a user-defined analysis of Kendall
County with site-specific parcel data provided by the county.
HAZUS-MH estimates the 100-year flood would damage 439 buildings with building related
flood losses totaling approximately $32.1 million. The total estimated numbers of damaged
buildings are given in Table 4-21. Figure 4-6 depicts the Kendall County parcel points that fall
within the 100-year floodplain. Figure 4-7 highlights damaged buildings within the floodplain
areas in urban areas.

Critical Facilities
A critical facility will encounter many of the same impacts as other buildings within the flood
boundary. These impacts can include structural failure, extensive water damage to the facility
and loss of facility functionality(e.g. a damaged police station will no longer be able to serve the
community). A map and list of all critical facilities is included as Appendix F.
The analysis identified Plano Sewage Treatment Plant, the Oswego Pump House, and the
Farnsworth House as the only critical facilities subject to flooding. Figure 4-8 shows the location
of these three critical facilities.

Infrastructure
The types of infrastructure that could be impacted by a flood include roadways, utility
lines/pipes, railroads, and bridges. Since an extensive inventory of the infrastructure is not
available for this plan, it is important to emphasize that any number of these items could become
damaged in the event of a flood. The impacts to these items include broken, failed, or impassable
roadways; broken or failed utility lines (e.g. loss of power or gas to community); or railway
failure from broken or impassable railways. Bridges could also fail or become impassable,
causing traffic risks.
Vulnerability Analysis for Flash Flooding
Flash flooding could affect any low lying location within this jurisdiction; therefore, a significant
portion of county's population and buildings are vulnerable to a flash flood. These structures can
expect the same impacts as discussed in a riverine flood. A map and list of all critical facilities is
included as Appendix F.
Kendall County Multi-Hazard Mitigation Plan Page 49 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
Vulnerability Analysis for Dam and Levee Failure
An EAP is required to assess the effect of dam failure on these communities. In order to be
considered creditable flood protection structures on FEMA's flood maps, levee owners must
provide documentation to prove the levee meets design, operation, and maintenance standards
for protection against the "one-percent-annual chance" flood.
Vulnerability to Future Assets/Infrastructure for Flooding
Flash flooding may affect any low lying or poorly drained location within the county; therefore
many buildings and infrastructure are vulnerable to flash flooding. Currently, the Kendall County
Planning, Building, and Zoning Department reviews new development within the unincorporated
parts of the County for compliance with the County's Zoning ordinances. At this time no
construction is planned within the area of the 100-year floodplain. Therefore, there is no new
construction which will be vulnerable to a 100-year flood.
Vulnerability to Future Assets/Infrastructure for Dam and Levee Failure
The Kendall County Planning, Building, and Zoning Department reviews new development
within the unincorporated parts of the County for compliance with the County's Zoning
ordinances.
Analysis of Community Development Trends
Controlling floodplain development is the key to reducing flood-related damages. Areas with
recent development within the county may be more vulnerable to drainage issues. Storm drains
and sewer systems are usually most susceptible. Damage to these can cause the back up of water,
sewage, and debris into homes and basements, causing structural and mechanical damage as well
as creating public health hazards and unsanitary conditions.

4.4.3 Earthquake Hazard
Hazard Definition for Earthquake Hazard
An earthquake is a sudden, rapid shaking of the earth caused by the breaking and shifting of rock
beneath the earth's surface. For hundreds of millions of years, the forces of plate tectonics have
shaped Earth as the huge plates that form the earth's surface move slowly over, under, and past
each other. Sometimes the movement is gradual. At other times, the plates are locked together
unable to release the accumulating energy. When the accumulated energy grows strong enough,
the plates break free causing the ground to shake.
Most earthquakes occur at the boundaries where the plates meet; however, some earthquakes
occur in the middle of plates, as is the case for seismic zones in the Midwestern United States.
The most seismically active area in the Midwest is the New Madrid Seismic Zone. Scientists
have learned that the New Madrid fault system may not be the only fault system in the Central
U.S. capable of producing damaging earthquakes. The Wabash Valley fault system in Illinois
and Indiana shows evidence of large earthquakes in its geologic history, and there may be other,
as yet unidentified, faults that could produce strong earthquakes.
Ground shaking from strong earthquakes can collapse buildings and bridges; disrupt gas, electric,
and phone service; and sometimes trigger landslides, avalanches, flash floods, fires, and huge
destructive ocean waves (tsunamis). Buildings with foundations resting on unconsolidated
landfill and other unstable soil and trailers and homes not tied to their foundations are at risk
because they can be shaken off their mountings during an earthquake. When an earthquake
occurs in a populated area it may cause deaths, injuries, and extensive property damage.
The possibility of the occurrence of a catastrophic earthquake in the central and eastern United
States is real as evidenced by history and described throughout this section. The impacts of
significant earthquakes affect large areas, terminating public services and systems needed to aid
the suffering and displaced. These impaired systems are interrelated in the hardest struck zones.
Power lines, water and sanitary lines, and public communication may be lost; and highways,
railways, rivers, and ports may not allow transportation to the affected region. Furthermore,
essential facilities, such as fire and police departments and hospitals, may be disrupted if not
previously improved to resist earthquakes.
As with hurricanes, mass relocation may be necessary, but the residents who are suffering from
the earthquake can neither leave the heavily impacted areas nor receive aid or even
communication in the aftermath of a significant event.
Magnitude, which is determined from measurements on seismographs, measures the energy
released at the source of the earthquake. Intensity measures the strength of shaking produced by
the earthquake at a certain location and is determined from effects on people, human structures,
and the natural environment. Earthquake magnitudes and their corresponding intensities are
listed in Tables 4-22 and 4-23.

Previous Occurrences for Earthquake Hazard
Numerous instrumentally measured earthquakes have occurred in Illinois. In the past few
decades, with many precise seismographs positioned across Illinois, measured earthquakes have
varied in magnitude from very low microseismic events of M=1-3 to larger events up to M=5.4.
Microseismic events are usually only detectable by seismographs and rarely felt by anyone. The
most recent earthquake in northern Illinois—as of the date of this report—occurred on February
10, 2010 at 3:59:35 local time about 3.0 km (2 miles) east-northeast of Virgil, IL and measured
3.8 in magnitude.
The consensus of opinion among seismologists working in the Midwest is that a magnitude 5.0
to 5.5 event could occur virtually anywhere at any time throughout the region. Earthquakes
occur in Illinois all the time, although damaging quakes are very infrequent. Illinois earthquakes
causing minor damage occur on average every 20 years, although the actual timing is extremely
variable. Most recently, a magnitude 5.2 earthquake shook southeastern Illinois on April 18,
Kendall County Multi-Hazard Mitigation Plan Page 52 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
2008, causing minor damage in the Mt Carmel, IL area. Earthquakes resulting in more serious
damage have occurred about every 70 to 90 years mainly in Southern Illinois.
Seismic activity on the New Madrid Seismic Zone of southeastern Missouri is very significant
both historically and at present. On December 16, 1811 and January 23 and February 7 of 1812,
three earthquakes struck the central U.S. with magnitudes estimated to be 7.5-8.0. These
earthquakes caused violent round cracking and volcano-like eruptions of sediment (sand blows)
over an area of>10,500 km , and uplift of a 50 km by 23 km zone (the Lake County uplift). The
shaking collapsed scaffolding on the Capitol in Washington, D.C., and was felt over a total area
of over 10 million kM2 (the largest felt area of any historical earthquake). Of all the historical
earthquakes that have struck the U.S., an 1811-style event would do the most damage if it
recurred today.
The New Madrid earthquakes are especially noteworthy because the seismic zone is in the center
of the North American Plate. Such intraplate earthquakes are felt, and do damage, over much
broader areas than comparable earthquakes at plate boundaries. The precise driving force
responsible for activity on the New Madrid seismic zone is not known, but most scientists infer
that it is compression transmitted across the North American Plate. That compression is focused
on New Madrid because it is the site of a Paleozoic structure—the Reelfoot Rift—which is a
zone of weakness in the crust.
The United States Geological Survey (USGS) and the Center for Earthquake Research and
Information (CERI) at the University of Memphis estimate the probability of a repeat of the
1811-1812 type earthquakes(magnitude 7.5-8.0)is 7 0/0-10% over the next 50 years (USGS Fact
Sheet 2006-3125.) Frequent large earthquakes on the New Madrid seismic zone are geologically
puzzling because the region shows relatively little deformation. Three explanations have been
proposed: 1) recent seismological and geodetic activity is still a short-term response to the 1811-
12 earthquakes; 2) activity is irregular or cyclic; or 3) activity began only in the recent geologic
past. There is some dispute over how often earthquakes like the 1811-12 sequence occur. Many
researchers estimate a recurrence interval of between 550 and 1100 years; other researchers
suggest that either the magnitude of the 1811-12 earthquakes have been over-stated, or else the
actual frequency of these events is less. It is fair to say, however,that even if the 1811-12 shocks
were just magnitude –7 events, they nonetheless caused widespread damage and would do the
same if another such earthquake or earthquake sequence were to strike today.

The earliest reported earthquake in Illinois was in 1795. This event was felt at Kaskaskia, IL for
a minute and a half and was also felt in Kentucky. At Kaskaskia, subterranean noises were heard.
Due to the sparse frontier population, an accurate location is not possible, and the shock may
have actually originated outside the state.
An intensity VI-VII earthquake occurred on April 12, 1883, awakening several people in Cairo,
IL. One old frame house was significantly damaged, resulting in minor injuries to the
inhabitants. This is the only record of injury in the state due to earthquakes.
Kendall County Multi-Hazard Mitigation Plan Page 53 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
On October 31, 1895 a large M6.8 occurred at Charleston, Missouri,just south of Cairo. Strong
shaking caused eruptions of sand and water at many places along a line roughly 30 km (20 mi)
long. Damage occurred in six states, but most severely at Charleston, with cracked walls,
windows shattered, broken plaster, and chimneys fallen. Shaking was felt in 23 states from
Washington, D.C. to Kansas and from southernmost Canada to New Orleans, LA.
A Missouri earthquake on November 4, 1905, cracked walls in Cairo. Aftershocks were felt over
an area of 100,000 square miles in nine states. In Illinois, it cracked the wall of the new
education building in Cairo and a wall at Carbondale, IL.
Among the largest earthquakes occurring in Illinois was the May 26, 1909 shock,which knocked
over many chimneys at Aurora. It was felt over 500,000 square miles and strongly felt in Iowa
and Wisconsin. Buildings swayed in Chicago where there was fear that the walls would collapse.
Just under two months later, a second Intensity VII earthquake occurred on July 18, 1909,
damaged chimneys in Petersburg, IL, Hannibal, MO, and Davenport, IA. Over twenty windows
were broken, bricks loosened and plaster cracked in the Petersburg area. This event was felt over
40,000 square miles.
On November 7, 1958, a shock along the Indiana border resulted in damage at Bartelso, Dale
and Maunie, IL. Plaster cracked and fell, and a basement wall and floor were cracked.
On August 14, 1965, a sharp but local shock occurred at Tamms, IL, a town of about 600
people. The magnitude 5 quake damaged chimneys, cracked walls, knocked groceries from the
shelves, and muddied the water supply. Thunderous earth noises were heard. This earthquake
was only felt within a 10 mile radius of Tamms, in communities such as Elco, Unity, Olive
Branch, and Olmsted, IL. Six aftershocks were felt.
An earthquake of Intensity VII occurred on November 9, 1968. This magnitude 5.3 shock was
felt over an area of 580,000 square miles in 23 states. Damage consisted of bricks being knocked
from chimneys, broken windows, toppled television antenna, and cracked plaster. There were
scattered reports of cracked foundations, fallen parapets, and overturned tombstones. Chimney
damage was limited to buildings 30 to 50 years old. Many people were frightened. Church bells
rang at Broughton and several other towns. Loud rumbling earthquake noise was reported in
many communities.
Dozens of other shocks originating in Missouri, Arkansas, Kansas, Nebraska, Tennessee,
Indiana, Ohio, Michigan, Kentucky, and Canada have been felt in Illinois without causing
damage. There have been three earthquakes slightly greater than magnitude 5.0 and Intensity
level VII which occurred in 1968, 1987 and 2008 and that were widely felt throughout southern
Illinois and the midcontinent.

Hazard Extent for Earthquake Hazard
The extent of the earthquake is countywide. One of the most critical sources of information that
is required for accurate assessment of earthquake risk is soils data. A National Earthquake
Hazards Reduction Program (NEHRP) compliant soils map was used for the analysis which was
provided by FEMA. The map identifies the soils most susceptible to failure.
Risk Identification for Earthquake Hazard
Based on historical information as well as current USGS and SIUC research and studies, future
earthquakes in Kendall County are possible but, large ( >5.5 M) earthquakes that would cause
catastrophic damage are unlikely. Severe to catastrophic earthquake damage is unlikely because
of the large distance (>300 miles) between Kendall County and the major Midwestern seismic
zones, the New Madrid Seismic Zone and the Wabash Valley Fault Zone. According to the RPI,
earthquakes are ranked as the number seven hazard.
RPI=Probability x Magnitude/Severity.
Probability x Magnitude = RPI
/Severity
1 x 2 = 2
Vulnerability Analysis for Earthquake Hazard
This hazard could impact the entire jurisdiction equally; therefore, the entire county's population
and all buildings are vulnerable to an earthquake and can expect the same impacts within the
affected area. To accommodate this risk, this plan will consider all buildings located within the
county as vulnerable.
Critical Facilities
All critical facilities are vulnerable to earthquakes. A critical facility would encounter many of
the same impacts as any other building within the county. These impacts include structural
failure and loss of facility functionality (e.g. a damaged police station will no longer be able to
serve the community). A map and list of all critical facilities is included as Appendix F.
Building Inventory
A table of the building exposure in terms of types and numbers of buildings for the entire county
is listed in Table 4-10. The buildings within the county can all expect the same impacts, similar
to those discussed for critical facilities. These impacts include structural failure and loss of
building function which could result in indirect impacts (e.g. damaged homes will no longer be
habitable causing residents to seek shelter).
Infrastructure
During an earthquake, the types of infrastructure that could be impacted include roadways,utility
lines/pipes, railroads, and bridges. Since an extensive inventory of the infrastructure is not
Kendall County Multi-Hazard Mitigation Plan Page 56 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
available to this plan, it is important to emphasize that any number of these items could become
damaged in the event of an earthquake. The impacts to these items include broken, failed, or
impassable roadways, broken or failed utility lines (e.g. loss of power or gas to community), and
railway failure from broken or impassable railways. Bridges could also fail or become
impassable causing traffic risks. Typical scenarios are described to gauge the anticipated impacts
of earthquakes in the county in terms of numbers and types of buildings and infrastructure.
The SIUC-Polis team reviewed existing geological information and recommendations for
earthquake scenarios. A deterministic and a probabilistic earthquake scenario were developed to
provide a reasonable basis for earthquake planning in Kendall County. The deterministic
scenario was a moment magnitude of 5.5 with the epicenter located in Kendall County along the
Sandwich Fault Zone south of Yorkville. This represents a realistic scenario for planning
purposes.
Additionally, the earthquake loss analysis included a probabilistic scenario based on ground
shaking parameters derived from U.S. Geological Survey probabilistic seismic hazard curves for
the earthquake with the 500-year return period. This scenario evaluates the average impacts of a
multitude of possible earthquake epicenters with a magnitude that would be typical of that
expected for a 500-year return period.
The following earthquake hazard modeling scenarios were performed:
• 5.5 magnitude earthquake local epicenter
• 500-year return period event
Modeling a deterministic scenario requires user input for a variety of parameters. One of the
most critical sources of information that is required for accurate assessment of earthquake risk is
soils data. Fortunately, a National Earthquake Hazards Reduction Program (NEHRP) soil
classification map exists for Illinois. NEHRP soil classifications portray the degree of shear-
wave amplification that can occur during ground shaking. FEMA provided a soils map and
liquefaction potential map that was used by HAZUS-MH.
Earthquake hypocenter depths in Illinois range from less than 1.0 to —25.0 km. The average
hypocenter depth, —10.0 km, was used for the deterministic earthquake scenario. For this
scenario type HAZUS-MH also requires the user to define an attenuation function. To maintain
consistency with the USGS's (2006) modeling of strong ground motion in the central United
States, the Toro et al. (1997) attenuation function was used for the deterministic earthquake
scenario.
The building losses are broken into two categories: direct building losses and business
interruption losses. The direct building losses are the estimated costs to repair or replace the
damage caused to the building and its contents. The business interruption losses are the losses
associated with inability to operate a business because of the damage sustained during the
earthquake. Business interruption losses also include the temporary living expenses for those
people displaced from their homes because of the earthquake.

Results for 5.5 Magnitude Earthquake in Kendall County
The results of the initial analysis, the 5.5 magnitude earthquake with an epicenter along the
Sandwich Fault Zone south of The United City of Yorkville, are depicted in Tables 4-24 and 4-
25 and Figure 4-10. HAZUS estimates that approximately 2,600 buildings will be at least
moderately damaged. This is more than 12% of the total number of buildings in the region. It is
estimated that 109 buildings will be damaged beyond repair.
The total building related losses totaled $253.6 million; 14% of the estimated losses were related
to the business interruption of the region. By far, the largest loss was sustained by the residential
occupancies, which comprised more than 64% of the total loss.

Before the earthquake, the region had 188 care beds available for use. On the day of the
earthquake, the model estimates that only 7 care beds (4%) are available for use by patients
already in medical care facilities and those injured by the earthquake. After one week, 58% of
the beds will be back in service. By day 30, 85% will be operational.
Results 5.0 Magnitude 500-Year Probabilistic Scenario
The results of the 500-year probabilistic analysis are depicted in Tables 4-26 and 4-27. HAZUS-
MH estimates that approximately 183 buildings will be at least moderately damaged. This is
more than 1% of the total number of buildings in the region. It is estimated that seven buildings
will be damaged beyond repair. The total building-related losses totaled $8.64 million; 27% of
the estimated losses were related to the business interruption of the region. By far, the largest
loss was sustained by the residential occupancies, which made up more than 60% of the total
loss.

Vulnerability to Future Assets/Infrastructure for Earthquake Hazard
New construction, especially critical facilities, will accommodate earthquake mitigation design
standards.
Analysis of Community Development Trends
Community development will occur outside of the low-lying areas in floodplains with a water
table within five feet of grade that is susceptible to liquefaction.
In Meeting #4, the MHMP team discussed specific mitigation strategies for potential earthquake
hazards. The discussion included strategies to harden and protect future, as well as existing,
structures against the possible termination of public services and systems including power lines,
water and sanitary lines, and public communication.

4.4.4 Thunderstorm Hazard
Hazard Definition for Thunderstorm Hazard
Severe thunderstorms are defined as thunderstorms with one or more of the following
characteristics: strong winds, large damaging hail, or frequent lightning. Severe thunderstorms
most frequently occur in Illinois during the spring and summer months, but can occur any month
of the year at any time of day. A severe thunderstorm's impacts can be localized or can be
widespread in nature. A thunderstorm is classified as severe when it meets one or more of the
following criteria.
• Hail of diameter 0.75 inches or higher
• Frequent and dangerous lightning
• Wind speeds equal to or greater than 58 miles per hour
Hail
Hail is a product of a strong thunderstorm. Hail usually falls near the center of a storm, however
strong winds occurring at high altitudes in the thunderstorm can blow the hailstones away from
the storm center, resulting in damage in other areas near the storm. Hailstones range from pea-
sized to baseball-sized,but hailstones larger than softballs have been reported on rare occasions.
Lightning
Lightning is a discharge of electricity from a thunderstorm. Lightning is often perceived as a
minor hazard, but in reality lightning causes damage to many structures and kills or severely
injures numerous people in the United States each year.
Severe Winds (Straight-Line Winds)
Straight-line winds from thunderstorms are a fairly common occurrence across Illinois. Straight-
line winds can cause damage to homes, businesses, power lines, and agricultural areas, and may
require temporary sheltering of individuals who are without power for extended periods of time.
Previous Occurrences for Thunderstorm Hazard
The NCDC database reported 37 hail storms in Kendall County since 1956. Hail storms occur
nearly every year in the late spring and early summer months. The most recent reported
occurrence was in October 2006 when severe thunderstorms developed over northeast Illinois.
Kendall County hail storms are identified in Table 4-28. Additional details for NCDC events are
included in Appendix D.

sources. However, these estimates are often preliminary in nature and may not match the final assessment of economic and
property losses related to a given weather event.
Geographic Location for Thunderstorm Hazard
The entire county has the same risk for occurrence of thunderstorms. They can occur at any
location within the county.
Hazard Extent for Thunderstorm Hazard
The extent of the historical thunderstorms varies in terms of the extent of the storm, the wind
speed, and the size of hail stones. Thunderstorms can occur at any location within the county.
Risk Identification for Thunderstorm Hazard
Based on historical information, the occurrence of future high winds, hail, and lightning is highly
likely. High winds with widely varying magnitudes are expected to happen. According to the
RPI, thunderstorms and high wind damage ranked as the number one hazard.
RPI=Probability x Magnitude/Severity.
Probability x Magnitude = RPI
/Severity
4 x 2 = 8
Vulnerability Analysis for Thunderstorm Hazard
Severe thunderstorms are an equally distributed threat across the entire jurisdiction; therefore,
the entire county's population and all buildings are vulnerable to a severe thunderstorm and can
expect the same impacts within the affected area. This plan will therefore consider all buildings
located within the county as vulnerable. The existing buildings and infrastructure in Kendall
County are discussed in Table 4-10.
Critical Facilities
All critical facilities are vulnerable to severe thunderstorms. A critical facility will encounter
many of the same impacts as any other building within the jurisdiction. These impacts include
structural failure, damaging debris(trees or limbs), roofs blown off or windows broken by hail or
high winds, fires caused by lightning, and loss of building functionality (e.g. a damaged police
station will no longer be able to serve the community). Table 4-9 lists the types and numbers of
Kendall County Multi-Hazard Mitigation Plan Page 66 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
all of the essential facilities in the area. A map and list of all critical facilities is included as
Appendix F.
Building Inventory
A table of the building exposure in terms of types and numbers of buildings for the entire county
is provided in Table 4-10. The buildings within the county can all expect the same impacts,
similar to those discussed for critical facilities. These impacts include structural failure,
damaging debris (trees or limbs), roofs blown off or windows broken by hail or high winds, fires
caused by lightning, and loss of building functionality (e.g. a damaged home will no longer be
habitable causing residents to seek shelter).
Infrastructure
During a severe thunderstorm, the types of infrastructure that could be impacted include
roadways, utility lines/pipes, railroads, and bridges. Since the county's entire infrastructure is
equally vulnerable it is important to emphasize that any number of these items could become
damaged during a severe thunderstorm. The impacts to these items include broken, failed, or
impassable roadways; broken or failed utility lines (e.g. loss of power or gas to community); or
railway failure from broken or impassable railways. Bridges could fail or become impassable
causing risk to traffic.
Potential Dollar Losses for Thunderstorm Hazard
A HAZUS-MH analysis was not completed for thunderstorms because the widespread extent of
such a hazard makes it difficult to accurately model outcomes.
To determine dollar losses for a thunderstorm hazard, the available NCDC hazard information
was condensed to include only thunderstorm hazards that occurred within the past ten years.
Kendall County's MHMP team then reviewed the property damages reported to NCDC and
made any applicable updates.
It was determined that since 1999, Kendall County has incurred $245,000 in damages relating to
thunderstorms, including hail, lightning, and high winds. The events resulting in property
damage are listed in Table 4-30.

The historical data has not been collected systematically or confirmed. As a result, potential
dollar losses for a future event cannot be precisely calculated; however, based on averages in the
last decade, it can be determined that Kendall County incurs an annual risk of approximately
$24,500 per year.
Vulnerability to Future Assets/Infrastructure for Thunderstorm Hazard
All future development within the county and all conununities will remain vulnerable to these
events.
Analysis of Community Development Trends
Preparing for severe storms will be enhanced if officials sponsor a wide range of programs and
initiatives to address the overall safety of county residents. New structures need to be built with
more sturdy construction, and those structures already in place need to be hardened to lessen the
potential impacts of severe weather. Community warning sirens to provide warning of
approaching storms are also vital to preventing the loss of property and ensuring the safety of
Kendall County residents.

4.4.5 Winter Storm Hazard
Hazard Definition for Winter Storm Hazard
Severe winter weather consists of various forms of precipitation and strong weather conditions.
This may include one or more of the following: freezing rain, sleet, heavy snow, blizzards, icy
roadways, extreme low temperatures, and strong winds. These conditions can cause human
health risks such as frostbite, hypothermia, and death.
Ice (glazing) and Sleet Storms
Ice or sleet, even in small quantities, can result in hazardous driving conditions and can cause
property damage. Sleet involves frozen raindrops that bounce when they hit the ground or other
objects. Sleet does not stick to trees and wires. Ice storms, on the other hand, involve liquid rain
that falls through subfreezing air and/or onto sub-freezing surfaces, freezing on contact with
those surfaces. The ice coats trees, buildings, overhead wires, and roadways, sometimes causing
extensive damage.
The most damaging winter storms in southern Illinois have been ice storms. Ice storms occur
when moisture-laden gulf air converges with the northern jet stream causing strong winds and
heavy precipitation. This precipitation takes the form of freezing rain coating power and
communication lines and trees with heavy ice. The winds will then cause the overburdened limbs
and cables to snap; leaving large sectors of the population without power, heat, or
communication.
Snowstorms
Significant snowstorms are characterized by the rapid accumulation of snow, often accompanied
by high winds, cold temperatures, and low visibility. A blizzard is categorized as a snowstorm
with winds of 35 miles per hour or greater and/or visibility of less than one-quarter mile for three
or more hours. The strong winds during a blizzard blow about falling and already existing snow,
creating poor visibility and impassable roadways. Blizzards have the potential to result in
property damage.
Illinois has repeatedly been struck by blizzards. Blizzard conditions cannot only cause power
outages and loss of communication, but also make transportation difficult. The blowing of snow
can reduce visibility to less than one-quarter mile, and the resulting disorientation makes even
travel by foot dangerous if not deadly.
Severe Cold
Severe cold is characterized by the ambient air temperature dropping to around O'F or below.
These extreme temperatures can increase the likelihood of frostbite and hypothermia. High
winds during severe cold events can enhance the air temperature's effects. Fast winds during
cold weather events can lower the wind chill factor (how cold the air feels on your skin). As a
result,the time it takes for frostbite and hypothermia to affect a person's body will decrease.
Previous Occurrences for Winter Storm Hazard
Kendall County Multi-Hazard Mitigation Plan Page 69 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
The NCDC database identified 33 winter storm and extreme cold events for Kendall County
since 1994. The most recent reported event occurred on January 14, 2009, when a small winter
storm moved across northern Illinois. Snowfall amounts ranged from 6 to 7 inches.
The NCDC winter storms are listed in Table 4-32. Additional details for NCDC events are

Geographic Location for Winter Storm Hazard
Severe winter storms are regional in nature. Most of the NCDC data is calculated regionally or in
some cases statewide.
Hazard Extent for Winter Storm Hazard
The extent of the historical winter storms varies in terms of storm location, temperature, and ice
or snowfall. A severe winter storm can occur anywhere in the jurisdiction.
Risk Identification for Winter Storm Hazard
Based on historical information and input from the planning team, the occurrence of future
winter storms is likely. Winter storms of varying magnitudes are expected to happen. According
to the RPI, winter storms were ranked as the number five hazard.
RPI=Probability x Magnitude/Severity.
Probability x Magnitude = RPI
/Severity
3 x 1 = 3
Vulnerability Analysis for Winter Storm Hazard
Winter storm impacts are equally distributed across the entire jurisdiction; therefore, the entire
county is vulnerable to a winter storm and can expect the same impacts within the affected
area. The building exposure for Kendall County, as determined from the building inventory, is
included in Table 4-10.
Critical Facilities
All critical facilities are vulnerable to a winter storm. A critical facility will encounter many of
the same impacts as other buildings within the jurisdiction. These impacts include loss of gas or
electricity from broken or damaged utility lines, damaged or impassable roads and railways,
broken water pipes, and roof collapse from heavy snow. Table 4-9 lists the types and numbers of
the essential facilities in the area. A map and list of all critical facilities is included as Appendix
F.
Building Inventory
A table of the building exposure in terms of types and numbers of buildings for the entire county

Kendall County's MHMP team then reviewed the property damages reported to NCDC and
made any applicable updates.
Review of NCDC Database and other historical records revealed Kendall County has not
incurred significant property damages over the last decade (1999-2009) from winter storms,
including sleet/ice and heavy snow.
Vulnerability to Future Assets/Infrastructure for Winter Storm Hazard
Any new development within the county will remain vulnerable to these events.
Analysis of Community Development Trends
Because the winter storm events are regional in nature future development will be equally
impacted across the county.

4.4.6 Hazardous Materials Storage and Transport Hazard
Hazard Definition for Hazardous Materials Storage and Transport Hazard
Illinois has numerous active transportation lines that run through many of its counties. Active
railways transport harmful and volatile substances between our borders every day. The
transportation of chemicals and substances along interstate routes is commonplace in Illinois.
The rural areas of Illinois have considerable agricultural commerce creating a demand for
fertilizers, herbicides, and pesticides to be transported along rural roads. These factors increase
the chance of hazardous material releases and spills throughout the state of Illinois.
The release or spill of certain substances can cause an explosion. Explosions result from the
ignition of volatile products such as petroleum products, natural and other flammable gases,
hazardous materials/chemicals, dust, and bombs. An explosion can potentially cause death,
injury, and property damage. In addition, a fire routinely follows an explosion which may cause
further damage and inhibit emergency response. Emergency response may require fire,
safety/law enforcement, search and rescue, and hazardous materials units.
Previous Occurrences for Hazardous Materials Storage and Transport Hazard
Kendall County has not experienced a significantly large-scale hazardous material incident at a
fixed site or during transport resulting in multiple deaths or serious injuries, although there have
been many minor releases that have put local firefighters, hazardous materials teams, emergency
management, and local law enforcement into action to try to stabilize these incidents and prevent
or lessen harm to Kendall County residents.
Geographic Location for Hazardous Materials Storage and Transport Hazard
The hazardous material hazards are countywide and are primarily associated with the transport of
materials via highway, railroad, and/or river barge.
Hazard Extent for Hazardous Materials Storage and Transport Hazard
The extent of the hazardous material hazard varies both in terms of the quantity of material being
transported as well as the specific content of the container.
Risk Identification for Hazardous Materials Release
Based on input from the planning team, the occurrence of a hazardous materials accident is
likely. According to the RPI, Hazardous Materials Storage and Transport ranked as the number
three hazard.
RPI=Probability x Magnitude/Severity.
Probability x Magnitude = RPI
/Severity
3 x 2 = 6

Vulnerability Analysis for Hazardous Materials Storage and Transport Hazard
Hazardous material impacts are an equally distributed threat across the entire jurisdiction;
therefore, the entire county is vulnerable to a hazardous material release and can expect the same
impacts within the affected area. The main concern during a release or spill is the population
affected. The building exposure for Kendall County, as determined from building inventory, is
included in Table 4-10. This plan will therefore consider all buildings located within the county
as vulnerable.
Critical Facilities
All critical facilities and communities within the county are at risk. A critical facility will
encounter many of the same impacts as any other building within the jurisdiction. These impacts
include structural failure due to fire or explosion and loss of function of the facility (e.g. a
damaged police station will no longer be able to serve the community). Table 4-9 lists the types
and numbers of all essential facilities in the area. A map and list of all critical facilities is
included as Appendix F.
Building Inventory
A table of the building exposure in terms of types and numbers of buildings for the entire county
is listed in Table 4-10. The buildings within the county can all expect the same impacts, similar
to those discussed for critical facilities. These impacts include structural failure due to fire or
explosion or debris and loss of function of the building (e.g. a damaged home will no longer be
habitable causing residents to seek shelter).
Infrastructure
During a hazardous material release the types of infrastructure that could be impacted
include roadways, utility lines/pipes, railroads, and bridges. Since an extensive inventory of the
infrastructure is not available to this plan it is important to emphasize that any number of these
items could become damaged in the event of a hazardous material release. The impacts to these
items include broken, failed, or impassable roadways; broken or failed utility lines (e.g. loss of
power or gas to community); and railway failure from broken or impassable railways. Bridges
could fail or become impassable causing risk to traffic.
In terms of numbers and types of buildings and infrastructure, typical scenarios are described to
gauge the anticipated impacts of hazardous material release events in the county.
The U.S. EPA's ALOHA (Areal Locations of Hazardous Atmospheres) model was utilized to
assess the area of impact for an anhydrous ammonia release at the intersection of Burlington
Northern and Santa Fe Railroad and Fox River Drive Road in Plano. The target area was selected
for three primary reasons: 1) the high volume traffic, 2) the area is highly populated and 3)
proximity to several critical facilities.
Chlorine is a greenish yellow gas with a pungent suffocating odor. The gas liquefies at-35°C and
room pressure or will liquefy from pressure applied at room temperature. Contact with

unconfined liquid chlorine can cause frostbite from evaporative cooling. Chlorine does not burn,
but, like oxygen, supports combustion. The toxic gas can have adverse health effects from either
long-term inhalation of low concentrations of vapors or short-term inhalation of high
concentrations. Chlorine vapors are much heavier than air and tend to settle in low areas.
Chlorine is commonly used to purify water, bleach wood pulp, and make other chemicals
(NOAA Reactivity 2007).
Source: http://cameocliemicals.noaa.gov/chemical/2862
ALOHA is a computer program designed especially for use by people responding to chemical
accidents, as well as for emergency planning and training. Chlorine is a common chemical used
in industrial operations and can be found in either liquid or gas form. Rail and truck tankers
commonly haul Chlorine to and from facilities.
For this scenario, moderate atmospheric and climatic conditions with a slight breeze from the
west-southwest were assumed. The target area was chosen due to its proximity to the residential,
commercial, and essential facility locations. The geographic area covered in this analysis is
depicted in Figure 4-12.

Analysis
The ALOHA atmospheric modeling parameters, depicted in Figure 4-13, were based upon a
westerly wind speed of five miles per hour. The temperature was 70°F with 50% humidity and a
cloud cover of five-tenths skies.
The source of the chemical spill is a horizontal, cylindrical-shaped tank. The diameter of the tank
was set to 10.4 feet and the length set to 53 feet (33,500 gallons). At the time of its release, it was
estimated that the tank was 85% full. The chlorine in this tank is in its liquid state.
This release was based on a leak from a 2.5-inch-diameter hole, 12 inches above the bottom of
the tank. According to the ALOHA parameters, approximately 10,600 pounds of material would
be released per minute. The image in Figure 4-14 depicts the plume footprint generated by
ALOHA.

Confidence Lines
Acute Exposure Guideline Levels(AEGLs) are intended to describe the health effects on humans
due to once-in-a-lifetime or rare exposure to airborne chemicals. The National Advisory
Committee for AEGLs is developing these guidelines to help both national and local authorities,
as well as private companies, deal with emergencies involving spills or other catastrophic
exposures. As the substance moves away from the source, the level of substance concentration
decreases. Each color-coded area depicts a level of concentration measured in parts per million
(ppm). The image in Figure 4-15 depicts the plume footprint generated by ALOHA in ArcGIS.
• AEGL 3: Above this airborne concentration of a substance, it is predicted that the
general population, including susceptible individuals, could experience life-
threatening health effects or death. The red buffer(> 20.0 ppm) extends no more than
six miles from the point of release after one hour.
Kendall County Multi-Hazard Mitigation Plan Page 77 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
• AEGL 2: Above this airborne concentration of a substance, it is predicted that the
general population, including susceptible individuals, could experience irreversible
or other serious, long-lasting adverse health effects or an impaired ability to escape.
The orange buffer (> 2.0 ppm) extends no more than six miles from the point of
release after one hour.
• AEGL 1: Above this airborne concentration of a substance, it is predicted that the
general population, including susceptible individuals, could experience notable
discomfort, irritation, or certain asymptomatic nonsensory effects. However, the
effects are not disabling and are transient and reversible upon cessation of exposure.
The yellow buffer (> 0.5 ppm) extends more than six miles from the point of release
after one hour.
• Confidence Lines: The dashed lines depict the level of confidence in which the
exposure level will be contained. The ALOHA model is 95% confident that the
release will stay within this boundary.

Results
By summing the building inventory within all AEGL levels (AEGL 3: > 20.0 ppm, AEGL 2: >_
2.0 ppm and Level 1: >_ 0.5 ppm.), the GIS overlay analysis predicts that as many as 3,486
buildings could be exposed at a replacement cost of$1.06 billion. If this event were to occur,
approximately 9,100 people would be affected. The results are depicted in Figure 4-16.
The Assessor records often do not distinguish parcels by occupancy class when the parcels are
not taxable; therefore, the total number of buildings and the building replacement costs for
government, religious/non-profit, and education may be underestimated.

Vulnerability to Future Assets/Infrastructure for Hazardous Materials Storage and
Transport Hazard
Any new development within the county will be vulnerable to these events, especially
development along major roadways.
Analysis of Community Development Trends
Because the hazardous material hazard events may occur anywhere within the county, future
development will be impacted. The major transportation routes and the industries located in
Kendall County pose a threat of dangerous chemicals and hazardous materials release.
Kendall County Multi-Hazard Mitigation Plan Page 82 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
4.4.7 Fire Hazard
Hazard Definition for Fire Hazard
This plan will address three major categories of fires for Kendall County: 1) tire/scrap fires; 2)
structural fires; and 3)wildfires.
Tire Fires
The state of Illinois generates thousands of scrap tires annually. Many of those scrap tires end up
in approved storage sites that are carefully regulated and controlled by federal and state officials.
However, scrap tires are sometimes intentionally dumped in unapproved locations throughout the
state. The number of unapproved locations cannot be readily determined. These illegal sites are
owned by private residents who have been continually dumping waste and refuse, including
scrap tires, at those locations for many years.
Tire disposal sites can be fire hazards, in large part, because of the enormous number of scrap
tires typically present at one site. This large amount of fuel renders standard firefighting
practices nearly useless. Flowing and burning oil released by the scrap tires can spread the fire to
adjacent areas. Tire fires differ from conventional fires in the following ways:
• Relatively small tire fires can require significant fire resources to control and extinguish.
• Those resources often cost much more than Kendall County government can absorb
compared to standard fire responses.
• There may be significant environmental consequences of a major tire fire. Extreme heat
can convert a standard vehicle tire into approximately two gallons of oily residue that
may leak into the soil or migrate to streams and waterways.
Structural Fires
Lightning strikes, poor building construction, and building condition are the main causes for
most structural fires in Indiana. Kendall County has a few structural fires each year countywide.
Wildfires
When hot and dry conditions develop, forests may become vulnerable to devastating wildfires. In
the past few decades an increased commercial and residential development near forested areas
has dramatically changed the nature and scope of the wildfire hazard. In addition, the increase in
structures resulting from new development strains the effectiveness of the fire service personnel
in the county.
Previous Occurrences for Fire Hazard
Kendall County has not experienced a significant or large-scale explosion at a fixed site or
transportation route that has resulted in multiple deaths or serious injuries.
Kendall County Multi-Hazard Mitigation Plan Page 83 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
Geographic Location for Fire Hazard
Fire hazards occur countywide and therefore affect the entire county. The forested areas in the
county have a higher chance of widespread fire hazard.
Hazard Extent for Fire Hazard
The extent of the fire hazard varies both in terms of the severity of the fire and the type of
material being ignited. All communities in Kendall County are affected by fire equally.
Risk Identification for Fire Hazard
Based on input from the planning team, a future occurrence of a fire or explosion is possible.
According to the RPI, fire/explosion is ranked as the number six hazard.
RPI=Probability x Magnitude/Severity.
Probability x Magnitude = RPI
/Severity
2 x 1 = 2
Vulnerability Analysis for Fire Hazard
This hazard impacts the entire jurisdiction equally; therefore, the entire population and all
buildings within the county are vulnerable to fires and can expect the same impacts within the
affected area.
Table 4-9 lists the types and numbers of all essential facilities in the area. A map and list of all
critical facilities is included as Appendix F.
The building exposure for Kendall County, as determined from the building inventory, is
included in Table 4-10. Because of the difficulty predicting which communities are at risk, the
entire population and all buildings have been identified at risk.
Critical Facilities
All critical facilities are vulnerable to fire hazards. A critical facility will encounter many of the
same impacts as any other building within the jurisdiction. These impacts include structural
damage from fire and water damage from efforts extinguishing fire. Table 4-9 lists the types and
numbers of essential facilities in the area. A map and list of all critical facilities is included as
Appendix F.
Building Inventory
A table of the building exposure in terms of types and numbers of buildings for the entire county
is provided in Table 4-10. Impacts to the general buildings within the county are similar to the
damages expected to the critical facilities. These impacts include structural damage from fire and
water damage from efforts to extinguish the fire.
Kendall County Multi-Hazard Mitigation Plan Page 84 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
Infrastructure
During a fire the types of infrastructure that could be impacted include roadways, utility
lines/pipes, railroads, and bridges. Since the county's entire infrastructure is equally vulnerable,
it is important to emphasize that any number of these items could become damaged during a fire.
Potential impacts include structural damage resulting in impassable roadways and power
outages.
Vulnerability to Future Assets/Infrastructure for Fire Hazard
Any future development will be vulnerable to these events.
Analysis of Community Development Trends
Fire hazard events may occur anywhere within the county, because of this future development
will be impacted.
Kendall County Multi-Hazard Mitigation Plan Page 85 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
Section 5 - Mitigation Strategy
The goal of mitigation is to reduce the future impacts of a hazard including property damage,
disruption to local and regional economies, and the amount of public and private funds spent to
assist with recovery. The goal of mitigation is to build disaster-resistant communities. Mitigation
actions and projects should be based on a well-constructed risk assessment,provided in Section 4
of this plan. Mitigation should be an ongoing process adapting over time to accommodate a
community's needs.
5.1 Community Capability Assessment
The capability assessment identifies current activities used to mitigate hazards. The capability
assessment identifies the policies, regulations,procedures, programs, and projects that contribute
to the lessening of disaster damages. The assessment also provides an evaluation of these
capabilities to determine whether the activities can be improved in order to more effectively
reduce the impact of future hazards. The following sections identify existing plans and mitigation
capabilities within all of the communities listed in Section 2 of this plan.
5.1.1 National Flood Insurance Program (NFIP)
Kendall County, all its jurisdictions are members of the NFIP expect Boulder Hill. Boulder Hill
does have an identified flood area but has chosen not to participate due to lack of interest or
perceived need. Kendall County will continue to educate this jurisdiction on the benefits of the
program.
HAZUS-MH identified approximately 439 structures are located within the Kendall County
Special Flood Hazard Area. However, 2,128 households paid flood insurance, insuring
$300,563,000 in property value. The total premiums collected amounted to $1,368,412, which on
average was $47,186 annually. From 1978 through 2007, 1,142 claims were filed totaling
$9,814,877. The average claim was $8,594.
The county and incorporated areas do not participate in the NFIP'S Community Rating System
(CRS). The CRS is a voluntary incentive program that recognizes and encourages community
floodplain management activities that exceed the minimum NFIP requirements. As a result, flood
insurance premium rates are discounted to reflect the reduced flood risk resulting from the
community actions meeting the three goals of the CRS: 1) reduce flood losses; 2) facilitate
accurate insurance rating; and 3)promote the awareness of flood insurance.
Table 5-1 identifies each community and the date each participant joined the NFIP.

5.1.2 Stormwater Management Stream Maintenance Ordinance
The most recent Stormwater Management Ordinance for Kendall County was enacted in
September of 2002. The overall goal of the Stormwater Management Ordinance is to have no
change in runoff rate or volume from pre-development conditions. For every development
project a stormwater management plan must be created. The stormwater management plan must
address the following issues: minimization of increases in runoff volume and rates, water quality
and multiple uses, release rates, detention basin outlet design and storage requirements, drainage
system design and evaluation, methods of generating runoff hydrographs, wet detention basin
design, wetland and dry detention basin design, detention in flood plains, wetland protection,
urban area drainage, infiltration practices, and safety an maintenance considerations.
Several other jurisdictions within Kendall County have similar stormwater management
ordinances except for the Village of Lisbon and Boulder Hill CDP which is not available.
5.1.3 Zoning Management Ordinance
The first zoning ordinance for Kendall County was passed on January 16, 1940. The Kendall
County zoning ordinance was recently revised in October 19, 2010. The overall goal of the
zoning ordinance, which still pertains today, is to promote the public health, safety, morals,
comfort and the general welfare of the people of Kendall County. The full text of the zoning
ordinance for Kendall County can be found on the county website along with several other
ordinances. The website also has links to the other jurisdictions within Kendall County. Table

5.1.7 Building Codes
Unincorporated Kendall County uses the International Building Code as their guide for building
standards. All other jurisdictions within Kendall County also use the International Building
Code except for the Village of Lisbon and Boulder Hill whose building codes are not available.
5.2 Mitigation Goals
In Section 4 of this plan, the risk assessment identified Kendall County as prone to eight hazards.
The MHMP planning team members understand that although hazards cannot be eliminated
altogether, Kendall County can work toward building disaster-resistant communities. Following
are a list of goals, objectives, and actions. The goals represent long-term, broad visions of the
overall vision the county would like to achieve for mitigation. The objectives are strategies and
steps that will assist the communities in attaining the listed goals.
Goal 1: Lessen the impacts of hazards to new and existing infrastructure
(a) Objective: Retrofit critical facilities and structures with structural design practices
and equipment that will withstand natural disasters and offer weather-proofing.
(b) Objective: Equip public facilities and communities to guard against damage caused
by secondary effects of hazards.
(c)Objective: Minimize the amount of infrastructure exposed to hazards.
(d) Objective: Evaluate and strengthen the communication and transportation abilities
of emergency services throughout the community.
(e) Objective: Improve emergency sheltering in the community.
Goal 2: Create new or revise existing plans/maps for the community
(a)Objective: Support compliance with the NFIP.
(b) Objective: Review and update existing, or create new, community plans and
ordinances to support hazard mitigation.
(c) Objective: Conduct new studies/research to profile hazards and follow up with
mitigation strategies.
Goal 3: Develop long-term strategies to educate community residents on the hazards
affecting their county
(a)Objective: Raise public awareness on hazard mitigation.
(b) Objective: Improve education and training of emergency personnel and public
officials.
5.3 Mitigation Actions/Projects
Kendall County Multi-Hazard Mitigation Plan Page 89 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
Upon completion of the risk assessment and development of the goals and objectives, the
planning committee was provided a list of the six mitigation measure categories from the FEMA
State and Local Mitigation Planning How to Guides. The measures are listed as follows:
• Prevention: Government, administrative, or regulatory actions or processes that
influence the way land and buildings are developed and built. These actions also include
public activities to reduce hazard losses. Examples include planning and zoning, building
codes, capital improvement programs, open space preservation, and stormwater
management regulations.
• Property Protection: Actions that involve the modification of existing buildings or
structures to protect them from a hazard or removal from the hazard area. Examples
include acquisition, elevation, structural retrofits, storm shutters, and shatter-resistant
glass.
• Public Education and Awareness: Actions to inform and educate citizens, elected
officials, and property owners about the hazards and potential ways to mitigate them.
Such actions include outreach projects, real estate disclosure, hazard information centers,
and school-age and adult education programs.
• Natural Resource Protection: Actions that, in addition to minimizing hazard losses,
preserve or restore the functions of natural systems. These actions include sediment and
erosion control, stream corridor restoration, watershed management, forest and vegetation
management, and wetland restoration and preservation.
• Emergency Services: Actions that protect people and property during and immediately
after a disaster or hazard event. Services include warning systems, emergency response
services, and protection of critical facilities.
• Structural Projects: Actions that involve the construction of structures to reduce the
impact of a hazard. Such structures include dams, levees, floodwalls, seawalls, retaining
walls, and safe rooms.
After Meeting #3, held June 9, 2010, MHMP members were presented with the task of
individually listing potential mitigation activities using the FEMA evaluation criteria. The
MHMP members brought their mitigation ideas to Meeting#4 which was held August 11, 2010.
The evaluation criteria (STAPLE+E) involved the following categories and questions.
Social:
• Will the proposed action adversely affect one segment of the population?
• Will the action disrupt established neighborhoods, break up voting districts, or cause the
relocation of lower income people?
Kendall County Multi-Hazard Mitigation Plan Page 90 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
Technical:
• How effective is the action in avoiding or reducing future losses?
• Will it create more problems than it solves?
• Does it solve the problem or only a symptom?
• Does the mitigation strategy address continued compliance with the NFIP?
Administrative:
• Does the jurisdiction have the capability (staff, technical experts, and/or funding) to
implement the action, or can it be readily obtained?
• Can the community provide the necessary maintenance?
• Can it be accomplished in a timely manner?
Political:
• Is there political support to implement and maintain this action?
• Is there a local champion willing to help see the action to completion?
• Is there enough public support to ensure the success of the action?
• How can the mitigation objectives be accomplished at the lowest cost to the public?
Legal:
• Does the community have the authority to implement the proposed action?
• Are the proper laws, ordinances, and resolution in place to implement the action?
• Are there any potential legal consequences?
• Is there any potential community liability?
• Is the action likely to be challenged by those who may be negatively affected?
• Does the mitigation strategy address continued compliance with the NFIP?
Economic:
• Are there currently sources of funds that can be used to implement the action?
• What benefits will the action provide?
• Does the cost seem reasonable for the size of the problem and likely benefits?
• What burden will be placed on the tax base or local economy to implement this action?
• Does the action contribute to other community economic goals such as capital
improvements or economic development?
• What proposed actions should be considered but be "tabled" for implementation until
outside sources of funding are available?
Environmental:
• How will this action affect the environment(land, water, endangered species)?
• Will this action comply with local, state, and federal environmental laws and regulations?
• Is the action consistent with community environmental goals?
5.4 Implementation Strategy and Analysis of Mitigation Projects
Implementation of the mitigation plan is critical to the overall success of the mitigation planning
process. The first step is to decide, based upon many factors, which action will be undertaken
first. In order to pursue the top priority first, an analysis and prioritization of the actions is
Kendall County Multi-Hazard Mitigation Plan Page 91 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
important. Some actions may occur before the top priority due to financial, engineering,
environmental,permitting, and site control issues. Public awareness and input of these mitigation
actions can increase knowledge to capitalize on funding opportunities and monitoring the
progress of an action.
In Meeting #4, the planning team prioritized mitigation actions based on a number of factors. A
rating of high, medium, or low was assessed for each mitigation item and is listed next to each
item in Table 5-5. The factors were the STAPLE+E (Social, Technical, Administrative, Political,
Legal, Economic, and Environmental) criteria listed in Table 5-4.
Table 5-4: STAPLE+E planning factors
S—Social Mitigation actions are acceptable to the community if they do not adversely affect a particular
segment of the population,do not cause relocation of lower income people,and if they are
compatible with the community's social and cultural values.
T—Technical Mitigation actions are technically most effective if they provide a long-term reduction of losses and
have minimal secondary adverse impacts.
A—Administrative Mitigation actions are easier to implement if the jurisdiction has the necessary staffing and funding.
P—Political Mitigation actions can truly be successful if all stakeholders have been offered an opportunity to
participate in the planning process and if there is public support for the action.
L—Legal It is critical that the jurisdiction or implementing agency have the legal authority to implement and
enforce a mitigation action.
E—Economic Budget constraints can significantly deter the implementation of mitigation actions.Hence,it is
important to evaluate whether an action is cost-effective,as determined by a cost benefit review,
and possible to fund.
E—Environmental Sustainable mitigation actions that do not have an adverse effect on the environment,comply with
federal,state,and local environmental regulations,and are consistent with the community's
environmental goals,have mitigation benefits while being environmentally sound.
For each mitigation action related to infrastructure, new and existing infrastructure was
considered. Additionally, the mitigation strategies address continued compliance with the NFIP.
While an official cost benefit review was not conducted for any of the mitigation actions, the
estimated costs were discussed. The overall benefits were considered when prioritizing
mitigation items from high to low. An official cost benefit review will be conducted prior to the
implementations of any mitigation actions. Table 5-5 presents mitigation projects developed by
the planning committee, as well as actions that are ongoing or already completed. Since this is
the first mitigation plan developed for Kendall County, there are no deleted or deferred
mitigation items.

The Kendall County Emergency Management will be the local champions for the mitigation
actions. The County Commissioners and the city and town councils will be an integral part of the
implementation process. Federal and state assistance will be necessary for a number of the
identified actions.
5.5 Multi-Jurisdictional Mitigation Strategy
As a part of the multi-hazard mitigation planning requirements, at least two identifiable
mitigation action items have been addressed for each hazard listed in the risk assessment and for
each jurisdiction covered under this plan.
Each of the nine incorporated communities within and including Kendall County was invited to
participate in brainstorming sessions in which goals, objectives, and strategies were discussed
and prioritized. Each participant in these sessions was armed with possible mitigation goals and
strategies provided by FEMA, as well as information about mitigation projects discussed in
neighboring communities and counties. All potential strategies and goals that arose through this
process are included in this plan. The county planning team used FEMA's evaluation criteria to
gauge the priority of all items. A final draft of the disaster mitigation plan was presented to all
members to allow for final edits and approval of the priorities.
Kendall County Multi-Hazard Mitigation Plan Page 98 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
Section 6 - Plan Maintenance
6.1 Monitoring, Evaluating, and Updating the Plan
Throughout the five-year planning cycle, the Kendall County Emergency Management Agency
will reconvene the MHMP planning committee to monitor, evaluate, and update the plan on an
annual basis. Additionally, a meeting will be held during February 2011 to address the five-year
update of this plan. Members of the planning committee are readily available to engage in email
correspondence between annual meetings. If the need for a special meeting, due to new
developments or a declared disaster occurs in the county, the team will meet to update mitigation
strategies. Depending on grant opportunities and fiscal resources, mitigation projects may be
implemented independently by individual communities or through local partnerships.
The committee will review the county goals and objectives to determine their relevance to
changing situations in the county. In addition, state and federal policies will be reviewed to
ensure they are addressing current and expected conditions. The committee will also review the
risk assessment portion of the plan to determine if this information should be updated or
modified. The parties responsible for the various implementation actions will report on the status
of their projects, and will include which implementation processes worked well, any difficulties
encountered,how coordination efforts are proceeding, and which strategies should be revised.
Updates or modifications to the MHMP during the five-year planning process will require a
public notice and a meeting prior to submitting revisions to the individual jurisdictions for
approval. The plan will be updated via written changes, submissions as the committee deems
appropriate and necessary, and as approved by the county commissioners.
The GIS data used to prepare the plan was obtained from existing county GIS data as well as
data collected as part of the planning process. This updated HAZUS-MH GIS data has been
returned to the county for use and maintenance in the county's system. As newer data becomes
available, this updated data will be used for future risk assessments and vulnerability analyses.
6.2 Implementation through Existing Programs
The results of this plan will be incorporated into ongoing planning efforts since many of the
mitigation projects identified as part of this planning process are ongoing. Kendall County and
its incorporated jurisdictions will update the zoning plans and ordinances listed in Table 5-2 as
necessary and as part of regularly scheduled updates. Each community will be responsible for
updating its own plans and ordinances.
6.3 Continued Public Involvement
Continued public involvement is critical to the successful implementation of the MHMP.
Comments from the public on the MHMP will be received by the EMA director and forwarded
to the MHMP planning committee for discussion. Education efforts for hazard mitigation will be
ongoing through the EMA. The public will be notified of periodic planning meetings through
notices in the local newspaper. Once adopted, a copy of this plan will be maintained in each
jurisdiction and in the County EMA Office.

Introduction to the Pre-Disaster Mitigation Planning Process
The meeting is called to order
Narrative: A power-point presentation was given by Jonathan Remo. He explained that this
project is in response to the Disaster Mitigation Act of 2000. The project is funded by a grant
awarded by FEMA. A twenty-five percent match will be required from the county to fund this
project. The county match will be met by sweat equity and GIS data acquired from the County
Assessor's Office. The sweat equity will be an accumulation of time spent at the meetings, on
Kendall County Multi-Hazard Mitigation Plan Page 104 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
research assignments, surveys, along with the time spent reviewing and producing the planning
document.
Jonathan Remo introduced the Pre-Disaster Mitigation Website to the planning team. A
username and password was given to the planning team,which will grant them access to the web
site. The web site is used to schedule meetings,post contact information and download material
pertaining to the planning process.
Jonathan Remo divided the planning project into five to six meetings. At the 1St meeting,the
planning team will review critical facility maps. The planning team will be asked to research
and verify the location of all critical facilities within the county. Jonathan stated that public
participation is very important throughout the planning process. He explained that all of the
meetings are open to the public but there will be a particular effort made to invite the public to
the 3`d meeting. At that meeting,the SIUC Geology Department will present historic accounts of
natural disasters that have affected this area. At the 2nd meeting the discussion will focus on
natural disasters that are relevant to this area. These hazards will be given a probability rating
and ranked by their occurrence and potential level of risk. Polis and SIUC Geology will research
these hazards and present them to the planning team. The 3`d meeting is publicized in order to
encourage public participation. Polis and SIUC Geology will produce a risk assessment in draft
form; each planning team member will get a copy. Also they will present strategies and projects
that FEMA and other counties have undertaken for the planning team to review. The 4th meeting
consists of a brain storming session focused on disasters that were analyzed in the risk
assessment report. The Planning Team will list strategies and projects that could be
implemented to mitigate the potential hazards that threaten the county. FEMA requires that for
every identified hazard, a strategy to mitigate the loss and damage must be in place. The
strategies may range from educational awareness to hardening a building or building a levee.
After the 4`"meeting the plan will be in its final draft form. At the 5t"meeting the planning team
will need to review the plan prior to sending it to IEMA. IEMA will review the plan and will
make recommendation to it as they see fit, then it is submitted to FEMA for review and approval.
Once the plan has been submitted to FEMA, local governments are eligible to apply for grants to
mitigate these established hazards. After FEMA approves the plan, it is sent back to the
Planning Team. At the 6t" meeting the Planning Team will present the Pre-Disaster Mitigation
Plan to the County Board for adoption. Incorporated communities must either adopt the county
plan or prepare its own plan, in order to access mitigation assistance from FEMA. The
communities are encouraged to participate and contribute to development of the plan. Once the
County Board has adopted the plan, each incorporated community will have the opportunity to
adopt the plan as well.
Jonathan Remo then introduced Megan Carlson of SIUC. Megan Carlson presented three maps
that identified critical facilities in the county. She asked the planning team to come up to review
the maps to identify any corrections that need to be made to the maps. She assigned research
homework arranged by categories to individual planning team members to locate missing or
incorrect critical facilities.
Meeting was adjourned.

The meeting was called to order.
Jonathan Remo thanked everyone for attending the meeting and stated that if the planning team
members needed extra mitigation strategy handbooks that they were available upon request. He
introduced John Buechler from the Polis Center that was in attendance that day also.
Jon Remo began by explaining that today's meeting would cover mitigation strategies that the
planning team believed would prevent or eliminate the loss of life and property. He explained
that the planning team should not make any reservations in the form of money or resources when
developing this list. John Buechler stepped in to direct the mitigation ideas brainstorming
period. Whenever possible,the planning team was directed to be specific about the location or
focus area of a strategy, in respect to being within a municipality or county wide. Each hazard
was addressed one at a time. The planning team listed new and current on-going mitigation

The meeting was called to order.
Terry Tichava opened the meeting with an overview of what was to happen from this point on
with the plan. He stated that the plan could be reviewed by the Planning Team members for
about 2 weeks so everyone would have ample amount of time look at and review the plan for any
discrepancies. He also stated that in approximately 3 weeks the plan would be sent to
IEMA/FEMA. They would then review it and if everything is OK with the plan, then we should
hear back from IEMA/FEMA hopefully by October for their approval.
Terry then explained that once it comes back approved,then a Resolution will have to be passed
by all municipalities. After they are passed, they needed to be returned Terry and he will
forward them on to FEMA. Once FEMA gets the Resolutions,they will send notification that
the municipality has a completed and approved plan.
Kendall County Multi-Hazard Mitigation Plan Page 118 of 174
Kendall County Multi-Hazard Mitigation Plan February 14, 2011
He also explained that once the plan is submitted to IEMA/FEMA for their review,the
municipalities can begin formulating and putting together their projects for funding. .
It was also explained to the planning team that FEMA will require a five-year update to the plan.
Terry told the planning team that in another five years, the members should come together again,
most likely under the direction of the ESDA Director, to review the plan and make any necessary
changes to it. He explained that FEMA will probably send out a reminder as to when this is
supposed to take place.
After Terry explained the above process, he pointed out specific tables and places in the plan that
needed clarification from the team members. After discussing a few changes, the planning team
members looked at the plan for a while longer.
Since there were no more comments about the plan, the meeting was adjourned.
