INTRODUCTION AND EXECUTIVE SUMMARY
Generally the first question asked when communities begin the process of preparing a Hazard
Mitigation Plan is very simply ―What is a Hazard Mitigation Plan and what is its intended
purpose?‖ First, it is imperative to define what precisely the term mitigation entails. One
definition of the term is stated most effectively by the Federal Emergency Management Agency
and is as follows: ―Mitigation is defined as any sustained action taken to reduce or eliminate
long-term risk to human life and property from a hazard event. Mitigation, also known as
prevention (when done before a disaster), encourages long-term reduction of hazard
vulnerability. The goal of mitigation is to decrease the need for response as opposed to simply
increasing the response capability.‖
With that definition in mind, a mitigation plan is a document that is intended to accomplish
several things. First, through the planning process the hazards that pose a risk to the community
will be identified. Second, an assessment of the hazards will be made that take into account
historic occurrence; the number of people that will be impacted; the area of the community that
will be affected; potential costs that the city, individuals, and organization may incur; the
likelihood of future occurrence; and the amount of warning time before an event occurs. Once
the assessment is completed, a list of current and historic mitigation efforts are discussed.
Through this discussion areas that can be improved upon are identified and developed into
―action steps‖.
Early in the planning process meeting attendees identify broad goals that briefly state what the
plan should attempt to accomplish. Every action step should, if implemented, work toward one
or more of the goals of the plan. An action step may suggest continuing a current mitigation
effort or propose a new project altogether.
Once the hazards have been assessed, mitigation steps identified, and the action steps have been
prioritized the plan makes some suggestions for implementation. Throughout the document there
are references to the cost of particularly identified projects. Some proposed projects are small in
scope and thus relatively low cost. Other projects are broad in nature and require more funding
than the local community can reasonably provide. Therefore, the final piece of the plan suggests
methods to implement the plan, how to keep the public involved, and what steps should be taken
by local government to ensure that the concept of hazard mitigation is always a priority.
In all, this plan details several million dollars of potential mitigation projects. Completion and
adoption of the plan does not, however, obligate the City of McGregor to the expenses associated
with the various action steps identified in the plan. The intent is to increase awareness of
mitigation measures that can be taken on behalf of the community, thereby increasing the
probability of finding the necessary funds through a variety of sources.
When implemented appropriately, mitigation projects can save lives, reduce property damage.
They are also cost-effective, and environmentally sound. This, in turn, can reduce the enormous
cost of disasters to property owners and all levels of government. In addition, mitigation can
protect critical community facilities, reduce exposure to liability, and minimize community
disruption.

THE PLANNING PROCESS
The first step in developing the Hazard Mitigation Plan was to hire a contractor to manage the
mitigation planning process. In May of 2008 the McGregor City Council contracted with
Consultant Steve Meyer to facilitate development of the City of McGregor’s Hazard Mitigation
Plan. On June 16, 2008, Meyer and Consultant Robyn Reese met with city council members and
city representatives to begin the planning process. The diverse group of people on the planning
committee possessed a variety of knowledge and backgrounds, yet all had some connection to
the goal of hazard mitigation. This group of people encompassed individuals representing local
government, law enforcement, fire and rescue, local emergency management, public utilities,
transportation, insurance, real estate, and citizen volunteers. Once established, this assembly was
considered to be the Hazard Mitigation Planning Committee. Beyond this core group of
individuals, great effort was made to inform local businesses and members of the general public
as well as neighboring communities of the planning process and invite all interested parties to
attend and contribute to the development of the plan. These efforts included mailed or e-mailed
invitations to hazard mitigation planning meetings for participants from city departments, school
system representatives, business and industry representatives, county emergency management,
county government, neighboring communities and residents of the communities. Public
announcements were also posted in key locations in the city and local newspapers. Details
pertaining to how notifications of these individuals and entities were conducted are provided in
Appendices 1-3 of this plan. Appendix 9, page 207 provides documentation of a public meeting
notice ran in The Outlook Newspaper. Following the establishment of the Hazard Mitigation
Planning Committee, three public meetings were held in order to establish what hazards the plan
would address, what the historical occurrence of those hazards in the community included, what
the probability of the hazard occurring again might be, and who would be likely effected should
a hazard occur. Furthermore, those who participated at the public meetings were charged with
identifying potential mitigation action steps that could be taken in order to reduce the
community’s risk to these hazards. Many of the identified action steps were projects that could
be accomplished by the local government independently. Other identified projects included
efforts that would either require the cooperation of two or more entities, or would not include the
local government at all. For each action step the parties that would most likely be responsible to
see that they were at least considered on an annual basis were identified in order to increase the
likelihood that the plan will be implemented. Finally, mitigation steps were prioritized.
Mitigation steps were determined for every hazard identified in the plan regardless of their
ranking as a high, medium or low risk. The three meetings that were held averaged two hours
and received varying degrees of attendance.
When the contractor had completed a draft of the McGregor Hazard Mitigation Plan a copy of
the plan was made available to all committee members for review. Additionally, as the plan was
being developed, review by those with particular expertise or knowledge in particular areas was
sought, particularly with regards to mitigation measures. The recommended revisions of
committee members and subject matter experts were incorporated into all sections of the plan.
The contractor who developed this plan and the planning committee reviewed applicable
ordinances and plans of the City of McGregor as well as those maintained by the Clayton County
Emergency Management Agency for their applicability to this Hazard Mitigation Plan. Among
the documents reviewed were the City of McGregor’s Building Codes and Ordinances, Clayton
County County-Wide Hazard Mitigation Plan and the Clayton County Strategic Performance
Plan. Where applicable the findings, recommendations and requirements of these plans were
incorporated into this plan.

HISTORY
The City of McGregor, Iowa is located on 2.5 square miles of land in Mendon Township located
in the northeast corner of Clayton County, Iowa. McGregor was founded as MacGregor's
Landing in 1847 by Alexandar MacGregor who had been operating a ferry across the Mississippi
River between Prairie du Chien, Wisconsin since 1837. MacGregor planned the new city as a six
block development. It was quickly populated and incorporated as McGregor in 1857. In that
same year, the Milwaukee & Mississippi Railroad finished building a railroad track from
Milwaukee, Wisconsin to Prairie du Chien, Wisconsin, thus connecting Lake Michigan with the
Mississippi River by rail. McGregor quickly became a major commercial center, and served as a
hub where grain from Iowa and Minnesota could be transported across the Mississippi and sent
on to Milwaukee via railroad. More railroads were built to connect McGregor with cities further
west, and the city of North McGregor (now Marquette, Iowa) was established just north of the
city to serve as the city's railroad terminus. After reaching McGregor from the west, trains were
disassembled and railroad cars were ferried across the Mississippi to continue on towards Lake
Michigan. During the 1870s, the population of McGregor exploded to over 5,500 as the city
became the busiest shipping port west of Chicago. In 1874, the system of ferrying railroad cars
across the river between North McGregor and Prairie du Chien, Wisconsin, was brought to an
end and the city’s population began to decline. Today the city's history is preserved in its
downtown business district, which contains many buildings constructed during the city's boom
years. Because of its colorful history and location beside the Mississippi River, the city has
become a popular summer tourist destination, and it is known for its many antique stores.
McGregor’s population according to the 2000 census stood at 871. The city has a public library;
a police department, volunteer fire department and ambulance service that are shared with the
neighboring City of Marquette (population 421). State Highway 76 and US Highway 18 are
major transportation routes through the city. Today the city’s economy is highly dependent upon
the Isle of Capri Casino in Marquette and the City of Prairie Du Chien, Wisconsin across the
Mississippi River.
GOVERNMENT
The City of McGregor is governed by a Mayor/Council form of government with five council
members and a mayor, all of whom are elected. The city also has a full-time professional city
administrator/clerk who serves as the treasurer, zoning administrator building inspections official
and floodplain manager. Other administrative staff includes a part-time clerical assistant; billing
clerk; a street superintendent; street foreman; assistant wastewater/streets person; water operator;
head lineman; assistant lineman; police chief, librarian and 2 assistant librarians.
PREVIOUS HAZARD MITIGATION PLANS
In August 2002, the City of McGregor adopted a Hazard Mitigation Plan developed by the Upper
Explorerland Regional Planning Commission. The plan was not DMA2000 compliant and did
not receive FEMA approval.
PROPERTY VALUE
The total assessed value of all property in the City of McGregor as detailed from information
provided by the McGregor City Clerk was $47,437,569 on January 1, 2007.

BUSINESS AND INDUSTRY
The City of McGregor is home to 123 commercial businesses and industries mostly centered in
agricultural, tourism and human services interests. The Great River Care Center with 30
employees is the city’s largest employer. Other large employers include the MFL Mar Mac
Middle School with 30 employees, the City of McGregor with 12 employees and Agri-Bunge
with 12 employees.
BUILDING REGULATIONS
The City of McGregor has various ordinances regulating development and building construction
in the city. Chapters of the city’s code relative to development and building construction include:
Chapter 145 – Dangerous Buildings
Chapter 146 – Mobile Homes and mobile Home Parks
Chapter 150 – Building Numbering
Chapter 151 – Trees
Chapter 155 – Building Code (Permits)
Chapter 156 – Sign Code
Chapter 160 – Flood Plain Regulations
Chapter 165 –Zoning Regulations
Chapter 166 – Subdivision Regulations
Certain provisions of the Iowa State Building Code promulgated by the State Building Code
Commissioner or State Fire Marshall as provided by Iowa Code, Chapters 100 and 103A, are
mandatory and supersede the above standards when they conflict.
The City of McGregor adopted a land use plan in 1970. The plan has not been updated.
ECONOMIC DEVELOPMENT
The McGregor-Marquette Chamber of Commerce functions as the City of McGregor’s economic
development entity. The chamber maintains an office at 146 Main Street in McGregor. In
addition to the McGregor-Marquette Chamber of Commerce, the Clayton County Economic
Development Group assists communities in the county with development and promotional
efforts.
One of the key elements of the local economy is tourism and gambling. Recreational pursuits
relative to the Mississippi River and the city’s old river town aura are a draw. Another huge draw
is the nearby Isle of Capri Riverboat Casino located in neighboring Marquette.

In order to remain a member of the National Flood Insurance Program, the community has
adopted and enforces a Floodplain Ordinance which is Chapter 160 of the Code of Ordinances
for the City of McGregor. The ordinance regulates what type of construction, if any, can occur
in identified flood hazard areas. By doing so, property owners in the community are eligible to
purchase flood insurance on property within the city limits, regardless of whether they are
actually in an identified floodplain.
NFIP COMMUNITY IDENTIFICATION (CIP) NUMBER
The identification number assigned to the City of McGregor, also known as a CID number, is
195183, made effective 1/19/1972. The first six digits of this number generally correspond with
the Community Panel Number found on the official Flood Insurance Rate Map for the
community and should be included in all flood insurance policies issued in the city.
16
November, 2008
NFIP COMMUNITY RATING SYSTEM
The City of McGregor is not currently active in the NFIP Community Rating System. Therefore,
no rating has been established.
FLOOD INSURANCE INFORMATION
As of June 30, 2008, there were 40 flood insurance policies in affect covering $5,248,500 worth
of property in the City of McGregor. Annual premium on these properties amounted to $31,711.
Since January 1, 1978, there have been 14 insurance claims for flood damage in the City of
McGregor. All totaled, $78,525 in property damage payments were made.
REPETITIVE LOSS PROPERTIES
The City of McGregor has no repetitive loss properties. Due to privacy issues no information is
available on the location or value of these structures.
VULNERABLE STRUCTURES
The City of McGregor has 103 structures that are located within flood zones A and B. These
structures include 54 classified as residential and 49 others including commercial, storage and
public or municipal facilities. Among the public facilities in the flood plain are: McGregor
Municipal Utilities; McGregor Sewage Treatment Plant; Well No. 6; McGregor City Hall;
McGregor Fire Station; McGregor Public Library; McGregor Museum and the Riverfront Park
Shelter House. Total value of all these structures from records provided by the City of McGregor
in September, 2008 is assessed at $11,862,723.
Within areas of the City of McGregor that have the possibility of being affected by a landslide
there are 40 residential and 25 commercial properties with an assessed value of $2.2 million.
All structures of the City of McGregor are vulnerable to the affects of a tornado and hazardous
materials events. Numerous scenarios and potential outcomes are possible with such events,
ranging from slight damage to total devastation of the community. Total devastation would mean
a loss of the city’s 374 residential structures, 74 commercial structures and 15 governmental
structures. Total assessed value of all such property in the City of McGregor is $47,437,569.
These assessed values were obtained from records maintained by the McGregor City Clerk’s
office.
There are currently no known plans for construction of any new structures in vulnerable areas of
the City of McGregor, namely those areas that would be within the flood plain or landslide areas.
DEVELOPMENT TREND
The City of McGregor experienced growth in most decades of the 20th century. The Farm Crisis of
the 1980’s that affected a majority of small communities in the Midwest slowed the population
growth in McGregor. From 1990 to 2000 the population of McGregor jumped by74 people from 797
to 871. This is related to new housing starts and an active housing program initiated by city
government. The city is also experiencing significant growth in tourism related business.

CLIMATE
Iowa’s climate is characterized by warm, generally moist summers and cold winters.
Temperatures vary considerably from season to season and, at times, from day to day. Although
total snowfall is rarely very great, the severity of the Iowa winter is often increased by high
winds that produce blizzard conditions and by prolonged periods of very low temperatures. The
City of McGregor lies in the northeast corner of Iowa and the climate is of the continental type.
The climate is marked by a great variation in temperature, humidity and precipitation.

WATERSHED/TOPOGRAPHY
Moderately sloping to steep slopes with well-drained soil, underlain with limestone bedrock
make up the area in and around McGregor, Iowa.
The City of McGregor is located in the Mississippi River Basin in northeast Iowa. In addition to
the huge watershed that flows into the Mississippi River from areas to the north that extends into
the states of Minnesota and Wisconsin, the city is uniquely located at the lower confluence of a
number of valleys and watersheds that drain into it essentially from all directions. All totaled, US
Geological Survey information documents a watershed area of 65,810 square miles that
influence the City of McGregor.

INVENTORY OF ASSETS
In order to identify the most appropriate mitigation techniques and projects, assets in the
community were identified. Assets that would be affected in the event of a large hazard that
could affect the entire community include all properties in the city. These hazards include:
Tornado/High Wind Event, Winter Storm, Thunderstorm/Lightning/Hail, Drought, Excessive
Heat and Earthquakes. In these events, the entire Community is the ―Hazard Area.‖ The only
information available for the community asset inventory is the total assessed value of all property
in the City of McGregor as detailed from information provided by the McGregor City Clerk’s
Office. On January 1, 2007 the total assessed value of all properties in the City of McGregor
stood at $47,437,569. This is the most recent information available.

HAZMAT Services
A regional Hazard Materials Team is on hand to assist the City of McGregor with a
Hazard Materials event or catastrophe. The Team is located within an hour of McGregor
and is operated by the Linn County Hazardous Materials Response Team headquartered
in Cedar Rapids. The Team assists Clayton County fire departments with hazard
materials emergency procedures. An evacuation plan is also in place in the City of
McGregor as part of the Clayton County Multi-Hazard Emergency Operations Plan that
can be used in conjunction with activities of the HAZMAT team and the McGregor Hook
and Ladder Co. No. 1 Fire Department.
Siren Warning System
The City of McGregor maintains a warning siren to alert residents of severe weather or other
threatening situations. The siren does have voice messaging capabilities.
Property Protection
The City of McGregor has undertaken some measures to mitigate the impact of floods on the
community. Most notable is a 1,500 feet US Army Corps of Engineers levee constructed in 1969
along Front Street. The levee was designed to withstand 100 year recurrent flood waters from the
Mississippi River. It protects 103 residential, commercial and municipal structures with a total
assessed value of $11,862,723. The city has also constructed a flood wall around the McGregor
Municipal Utilities plant. The Siegel Dam, Pike Peek Dam and Slaughter Dam were constructed
to create storm and flood water retention basins to protect the city in 1939. Two additional dams
were built by the City of McGregor to create retention basins in an area know as Methodist
Hollow. The City of McGregor is continuing to pursue further flood mitigation efforts.
36
November, 2008
Flood Research
One of the most important documents pertaining to flood hazards in the City of
McGregor is Flood Insurance Studies conducted by the Federal Emergency Management
Agency. Flood Insurance Studies are the preliminary requirement necessary for initial
participation in the National Flood Insurance Program. A FIRM map has been completed
For the City of McGregor. The map is number 195183A, with an effective date of
10/17/1975. FIRMettes from the map are found in Appendix 6, page 192 Flood Insurance
Studies and FIRM maps form the basis for Flood Plain Ordinances.
Floodplain Management
The City of McGregor has adopted a Floodplain Ordinance, which is Chapter 160 of the
city’s code of ordinances. The ordinance designates the McGregor City
Administrator/Clerk as the McGregor Floodplain Manager. The current City
Clerk/Administrator has not had any formal training in floodplain management.
Chapter 160 regulates development only in the city’s established Flood Plain District.
The ordinance establishes a development permit system which requires a permit within
the Flood Plain District. It also establishes specific performance standards for
construction within the Flood Plain District. As per the requirements of the ordinance,
most flood plain construction must be approved by the Iowa Department of Natural
Resources.
The Federal Insurance Administration manages the insurance component of the NFIP,
and works closely with FEMA’s Mitigation Directorate, which oversees the floodplain
management aspect of the program. Though little enforcement activities relative the
city’s floodplain ordinance have been undertaken; the City of McGregor remains in good
standing with the National Flood Insurance Program.
Other Mitigation Activities
Tornado/High Wind Event
Tornadoes have been known to cause great destruction. Numerous incidents of them
destroying entire buildings have been recorded in Clayton County. This being the case it
is important that mitigation efforts are made to protect people from this deadly force.
The most important measure in reducing the threat of injury is to be aware of the
oncoming danger. The City of McGregor currently has in place one siren that is
responsible for alerting the entire city of an impending tornado. The siren does have
voice transmission capabilities.
In addition to siren alerts in the community there are also a wide variety of early warning
messages provided through local radio and television stations as well as the cable
Weather Channel. Furthermore, the National Oceanic and Atmospheric Administration
(NOAA) Weather Radio provides an alternative media source for weather information.
NOAA Weather Radio is a nationwide network of radio stations broadcasting continuous
37
November, 2008
weather information direct from a nearby National Weather Service office. Weather
Radio broadcasts National Weather Service warnings, watches, forecasts and other
hazard information 24 hours a day.
In 2006 the Clayton County Emergency Management Commission purchased 100 NOAA
weather radios with DHS grant funds and distributed them free of charge to strategic
locations around the county such as county and city offices, libraries, schools, hospitals
and care facilities. This included every such location in the City of McGregor.
Shelters
The City of McGregor has unofficially designated the MFL MarMac Middle School with
an estimated capacity of 300 people and St. Mary’s Catholic Church with a capacity of
100 people as emergency shelters for the city. The city currently relies on the American
Red Cross of the Tri-States Chapter and the assistance of local volunteer organizations to
establish and operate shelter locations when necessary.
Communications
Emergency communications for the City of McGregor are handled through the Clayton
County Enhanced 911 System maintained and staffed by the Clayton County Sheriff’s
Office at 100 High Street, Elkader. At the center, multiple dispatchers, each with their
own workstation, are on duty at all times to handle emergency calls.
Electricity
The City of McGregor maintains its own electrical power generating plant that was built
in 1941. The McGregor Municipal Utilities plant is capable of providing electrical power
to the entire city and all of the city’s facilities in times of power outages. Total electrical
generating capacity of the plant is 2.0 MW. The plant has three generators installed in
1941, 1955 and 1977. The plant is used routinely during peak power usage situations to
supplement electrical power to the city. The plant is located in the flood plain of the city,
but it is protected by a concrete flood wall.

RISK ASSESSMENT
IDENTIFYING HAZARDS
In order to properly identify mitigation strategies and projects, the hazards that may affect the
City of McGregor must be identified. Iowa’s foundation for hazard mitigation is based on a hazard
analysis and risk assessment that is comprehensive and multi-hazard. This means that multiple
hazards that can possibly occur anywhere in the state are considered and analyzed, and that the
risk that each hazard poses is assessed in terms of a disaster or emergency situation that can be
created from that hazard.
Current hazard analysis and risk assessments, mostly from local plans that have been
received at HLSEM from local jurisdictions, were used to accumulate a total of all hazards that
occur in the State. The result of this input was the identification of 40 hazards in two major
categories, Natural (16) and Human-Caused/Combination hazards (24).
The hazards are as follows.
Natural: Thunderstorms/Lightning, Tornadoes, Windstorms, Hailstorms, Severe Winter
Storms, Extreme Heat, Expansive Soils, Earthquakes, Landslide, River Flood, Flash
Flood, Drought, Grass or Wildland fire, Sink Holes, Dam Failure, Levee Failure
Human-Caused/Combination: Fixed Hazardous Materials Incident, Transportation
Hazardous Materials Incident, Radiological Transportation, Air Transportation Incident,
Communications Failure, Energy Failure, Highway Transportation Incident, Pipeline
Transportation Incident, Rail Transportation Incident, Waterway Incident; Enemy
Attack, Public Disorder, Bio-Terrorism; Agro-Terrorism, Chemical Terrorism,
Radiological Terrorism, Conventional Terrorism, Cyber Terrorism; Human Disease
Incident; Human Disease Pandemic, Animal/Plant/Crop Disease, Structural Fire,
Structural Failure
The Hazard Profiles section lists the potential hazards to the city that were identified by
the planning committee. This section also discusses previous occurrences of the hazards, the
areas of the city most at risk from each hazard, and the populations most at risk. By identifying
the hazards and quantifying the risks, the city can better assess current mitigation strategies,
develop future mitigation strategies and identify needed mitigation projects.
It is important to note that the focus of mitigation is on reducing long-term risks of
damage or threats to public health and safety caused by hazards and their effects. Thus, in some
cases the hazards identified for mitigation will not include all of, or the same hazards, identified
for preparedness, response or recovery.
Hazards were identified through discussion by of the City of McGregor Hazard
Mitigation Planning Committee under direction from the contract planner and using documents
provided by FEMA and the State Emergency Management Division at a meeting held June 16,
2008. Hazards were eliminated if there were no historical occurrence and Committee members
felt there was no chance of occurrence in the future or the committee felt the city had adequate
resources to deal with the hazard.
41
November, 2008
At a meeting of the City of McGregor Hazard Mitigation Planning Committee held on June 16, 2008, the

HAZARDS NOT CONSIDERED
Hazards not considered in this plan and the rationale for not including them follows.


Drought: Though drought conditions have occurred in the McGregor area, specifically
with one recorded statewide drought event recorded by the National Climatic Data Center
in August of 1995, they have not been prolonged. The Hazard Mitigation Planning
Committee’s analysis based on historical occurrences is that drought does not present a
significant threat to the city and the welfare of its residents.
Earthquake: There has been no history of an earthquake that caused any damage to the
City of McGregor or any other city in the area and it is very improbable that one may
occur as shown in the following earthquake probability chart.
EARTHQUAKE PROBABILITY CHART FOR THE UNITED STATES


Expansive Soils: Expansive soils hazard and risk information provided by Iowa HLSEM,
the Multi-Hazard Identification and Risk Assessment document, USGS, and the County
Emergency Management Coordinator indicated the level of risk associated with
expansive soils was slight with little swelling clay potential in the McGregor area.
Hailstorm: National Climatic Data Center records indicate 3 hail events as having
impacted the City of McGregor since 8/19/1995, causing no reported property damages.
After reviewing the data, the Hazard Mitigation Planning Committee determined that the
level of damage was historically minor and residents of the City of McGregor and
facilities in the City of Elkader have the necessary resources to contend with hailstorm
incidents and could do nothing more to mitigate potential hail damages.
Sink Holes: Research efforts could find no incidents of sink holes occurring in the City of
McGregor, though they do occur in some areas of Clayton County. The Hazard
Mitigation Planning Committee determined that there are no mitigation measures that can
prevent a sink hole from occurring and any sink hole that would occur in the city would
have only minor consequences.
Grass or Wildland Fire: Minor grass and wildland fires have occurred in the City of
McGregor and the surrounding rural area. All such fires have been controlled with local
resources. The Hazard Mitigation Planning Committee determined that the level of fire
protection provided by the McGregor Hook and Ladder Co. No. 1 Fire Department and
fire departments it maintains mutual aid agreements with is sufficient to control any grass
or wildland fire in the area.
Air Transportation Incident: The City of McGregor has no airport nearby and is not part
of the flight path of any airport. The possibility of an air transportation incident affecting
the city are miniscule.
Fixed Radiological Incident: There is no facility within the City of McGregor that has an
amount of radiological materials that would pose a significant threat.
Radiological Transportation Incident: It could not be determined if any amounts of
radiological material was being transported through the City Of McGregor.

Rail Transportation Incident: The City of McGregor does have a railway that passes
through it. The Hazard Mitigation Planning Committee observed that there have only
been minor incidents relative to the rail line and that all crossings were sufficiently safe.
Therefore, no planning is necessary for rail transportation incidents.
Waterway/Waterbody Incident: Emergency response resources of the City of McGregor
and those resources that are available to the city via mutual aid agreements are sufficient
to manage any waterway or waterbody incident that could involve the city.
Enemy Attack: There has been no history of enemy attack on the City of McGregor and
the city does not have any facilities or locations that would be likely candidates for an
enemy attack.
Public Disorder: The Mar-Mac Unified Law Enforcement District has the resources
and can quickly gain additional resources through mutual aid with the Clayton County
Sheriff’s Office and neighboring police departments to suppress any public disorder
event.
Cyber Terrorism: After considering all relevant factors, the Hazard Mitigation Planning
Committee determined it could do nothing more than is already being done to prevent an
incident of cyber terrorism.
Chemical Terrorism: After considering all relevant factors, the Hazard Mitigation
Planning Committee determined it could do nothing more than is already being done to
prevent an incident of chemical terrorism.
Radiological: After considering all relevant factors, the Hazard Mitigation Planning
Committee did not feel the City of McGregor is at significant risk of a radiological
terrorist attack.
Agro-terrorism: After considering all relevant factors, the Hazard Mitigation Planning
Committee determined it could do nothing more than is already being done to prevent an
incident of agro-terrorism.
Pipeline Incident: The Hazard Mitigation Planning Committee did not feel there was an
underground pipeline of significant size within the City of McGregor that posed a threat
beyond what could be managed by local emergency response resources in an emergency
situation.
Animal/Plant/Crop Disease: After considering all relevant factors, the Hazard Mitigation
Planning Committee determined it could do nothing more than is already being done by
local, county, state and federal officials and agencies to prevent or prepare for incidents
of animal, plant or crop diseases.
Human Disease Incident: After considering all relevant factors, the Hazard Mitigation
local, county, state and federal officials and agencies to prevent or prepare for a human
disease incident.
Human Disease Pandemic: After considering all relevant factors, the Hazard Mitigation
local, county, state and federal officials and agencies to prevent or prepare for a human
disease pandemic.
Structural Failure: The Hazard Mitigation Planning Committee determined that there is
no structure within the City of McGregor that demonstrates a lack of structural integrity
such that it presents the probability of collapsing.

HAZARD PROFILES
Extreme Heat
Definition
Temperatures (including heat index) in excess of 100 degrees Fahrenheit or 3 successive
days of 90+ degrees Fahrenheit. A heat advisory is issued when temperatures reach 105
degrees and a warning is issued at 115 degrees.
Description
A prolonged period of excessive heat and humidity. The heat index is a number in degrees
Fahrenheit that tells how hot it really feels when relative humidity is added to the actual air
temperature. Exposure to full sunshine can increase the heat index by at least 15 degrees.
Extreme heat can impose stress on humans and animals. Heatstroke, sunstroke, cramps,
exhaustion, and fatigue are possible with prolonged exposure or physical activity due to the
body’s inability to dissipate the heat. Urban areas are particularly at risk because of air stagnation
and large quantities of heat absorbing materials such as streets and buildings. Extreme heat can
also result in distortion and failure of structures and surfaces such as roadways and railroad
tracks.
Historical
Occurrence
Probability
Vulnerability
Temperatures of 90 degrees or more occur in the City of McGregor area every
summer, sometimes for several days in a row. In Iowa, the record high
temperature of 110 for Des Moines was recorded in 1936. During July 1936, 12
record setting days topped 100 degrees in Des Moines. The record high
temperatures for Des Moines are above 90 degrees Fahrenheit beginning in
March and lasting through October. During the summers of 1997 and 1998, there
were a combined total of 31 days when the high temperature was 90 degrees
Fahrenheit or higher. There were 3 periods when temperatures were 90 degrees
or above for at least 3 consecutive days during the past 2 summers. Extreme heat
conditions, when they occur, are broad based. Therefore, events which occurred
in Des Moines would have impacted the City of McGregor also. The National
Climatic Data Center records indicate 7 incidents of heat waves or excessive heat
conditions that affected the City of McGregor since January 1, 1994.
Based on historical information, Iowa will likely experience about 26 days a year
with temperatures above 90 degrees. There is a very good chance that there will
also be a period of 3 consecutive days or more with temperatures in the 90s. It is
also common for the temperature to hit 100 degrees or more once every three
years during the summer months. Given these facts, the City of McGregor will
definitely experience extreme heat situations recurrently.
Elderly persons, small children, chronic invalids, those on certain medications or
drugs (especially tranquilizers and anticholinergics), and persons with weight
and alcohol problems are particularly susceptible to heat reactions. Healthy
individuals working outdoors in the sun and heat are vulnerable as well.
Individuals and families with low budgets as well as inner city dwellers can also
be susceptible due to poor access to air-conditioned rooms. See Heat Index Chart,
page 51.

Maximum
Threat
Most of the state would likely be impacted by extreme heat, but urban areas pose special
risks. The stagnant atmospheric conditions of the heat wave trap pollutants in urban areas
and add to the stresses of hot weather. Geographically, the entire City of McGregor
would be affected by an extreme heat event.
8
Severity
Extreme heat has broad and far-reaching impacts. These include significant loss
of life and illness, economic costs in transportation, agriculture, production,
energy, and infrastructure. Nationally, over the last 30 years, excessive heat
accounts for more reported deaths annually than hurricanes, floods, tornadoes,
and lightning combined. Transportation impacts include the loss of lift for
aircrafts, softening of asphalt roads, buckling of highways and railways, and
stress on automobiles and trucks (increase in mechanical failures). Livestock and
other animals are adversely impacted by extreme heat. High temperatures at the
wrong time inhibit crop yields as well. Electric transmission systems are
impacted when power lines sag in high temperatures. High demand for
3

electricity also outstrips supply, causing electric companies to have rolling black
outs. The demand for water also increases sharply during periods of extreme
heat. This can contribute to fire suppression problems for both urban and rural
fire departments.
Research efforts could not determine any estimates of damages to the City of
McGregor due to extreme heat conditions.
As with other weather phenomena, periods of extreme heat are predictable
within a few degrees within 3 days or so. Variations in local conditions can affect

Flash Flood
Definition
Description
A flood event occurring with little or no warning where water levels rise at an
extremely fast rate.
Flash flooding results from intense rainfall over a brief period, sometimes combined
with rapid snowmelt, ice jam release, frozen ground, saturated soil, or impermeable
surfaces. Most flash flooding is caused by slow-moving thunderstorms or
thunderstorms repeatedly moving over the same area. Flash flooding is an extremely
dangerous form of flooding which can reach full peak in only a few minutes and allows
little or no time for protective measures to be taken by those in its path. Flash flood
waters move at very fast speeds and can roll boulders, tear out trees, scour channels,
destroy buildings, and obliterate bridges. Flash flooding often results in higher loss of
life, both human and animal, than slower developing river and stream flooding.
Floods are the most common and widespread of all-natural disasters except fire.
In Iowa, as much as 21" of rain has fallen in a 24-hour period. As recently as June
1998, 13" of rain fell in western Iowa during a single rain event causing severe
flooding. The National Climatic Data Center lists 643 flash flooding/urban or
small stream flooding events occurring in Iowa since 1993.
For the City of McGregor, floods represent both the most frequent and most
devastating natural disaster. The City of McGregor is located in a low lying area
of the Mississippi River Basin in northeast Iowa. The Mississippi River borders
the city and is fed by a watershed that encompasses 65,810 square miles.
Historical
Occurrence
Probability
Flood stage for the Mississippi River as measured by a US Geological Service
Station in McGregor begins at 18 feet. The all time high crest occurred on April
24, 1965 when the river crested at 25.38 feet.. Of the many floods the City of
McGregor has endured, four floods that occurred on 5/16/1999, 5/21/2004,
5/23/2004 and 7/17/2007 are officially recorded by the National Weather Service
as flash floods.
The City of McGregor has undertaken some measures to mitigate the impact of
floods on the community. Most notable is a 1,500 feet US Army Corps of
Engineers levee constructed in 1969 along Front Street. The levee was designed to
withstand 100 year recurrent flood waters from the Mississippi River. It protects
103 residential, commercial and municipal structures with a total assessed value
of $11,862,723. The city has also constructed a flood wall around the McGregor
Municipal Utilities plant. The Siegel Dam, Pike Peek Dam and Slaughter Dam
were constructed to create storm and flood water retention basins to protect the
city in 1939. Two additional dams were built by the City of McGregor to create
retention basins in an area know as Methodist Hollow. The City of McGregor is
continuing to pursue further flood mitigation efforts.
As land is converted from fields or woodlands to roads and parking lots, it loses
its ability to absorb rainfall. Urbanization increases runoff 2 to 6 times over what
would occur on natural terrain. Portions of Iowa are very developed with
significant amounts of impervious surfaces. As more development occurs in the
watersheds, the amount of runoff produced also increases. Unless measures are
taken to reduce the amount of runoff (or slow its movement), flash floods will
continue to occur and possibly increase. Often, aging storm sewer systems are
not designed to carry the capacity currently needed to handle the increased storm
runoff in certain areas. While hundreds of homes and businesses have been
removed from the floodplains in the State of Iowa over the last decade, there are
many in the state remaining to be removed in areas that have a probability of
flooding.

Of Impact
November, 2008
With the City of McGregor’s history of flooding problems and disasters, it is
inevitable the city will witness more floods in the future, some of which may
cause damage.
Flash floods occur in all 50 states in the U.S. Particularly at risk are those in lowlying areas; close to dry creek beds or drainage ditches; near water; or
downstream from a dam, levee, or storage basin. People and property in areas
with insufficient storm sewers and other drainage infrastructure can also be put
at risk because the drains cannot rid the area of the runoff quickly enough.
Nearly half of all flash flood fatalities are auto-related. Motorists often try to
traverse water-covered roads and bridges and are swept away by the current. Six
inches of swiftly moving water can knock persons off their feet and only two feet
of water can float a full-sized automobile. Recreational vehicles and mobile
homes located in low-lying areas can also be swept away by the water
The City of McGregor has 103 structures that are located within the 100-year
flood plain. These structures include 54 classified as residential and 49 others
including commercial, storage and public or municipal facilities. Among the
public facilities in the flood plain are: McGregor Municipal Utilities; McGregor
Sewage Treatment Plant; Well No. 6; McGregor City Hall; McGregor Fire Station;
McGregor Public Library; McGregor Museum and the Riverfront Park Shelter
House. Total value of all these structures from records provided by the City of
McGregor in September, 2008 is assessed at $11,862,723.
Areas in a floodplain, downstream from a dam or levee, or in low-lying areas can
certainly be impacted. People and property located in areas with narrow stream
channels, saturated soil, or on land with large amounts of impermeable surfaces
are likely to be impacted in the event of a significant rainfall. Unlike areas
impacted by a river/stream flood, flash floods can impact areas a good distance
from the stream itself. Flash flood prone areas are not particularly those areas
adjacent to rivers and streams. Streets can become swift moving rivers, and
basements can become deathtraps because flash floods can fill them with water in
a manner of minutes.The Federal Emergency Management Agency has delineated
the probable extent of the 100-year flood hazard areas (see Diagram, page 57) in
most areas. These Flood Insurance Rate Maps (FIRMs) show properties affected
by the floods that have at least a 1% chance of occurring in any particular year.
Generally, these areas are in the floodplain or adjacent areas. Much of these areas
are parkland, agricultural areas, or conservation land, but residential and
commercial areas are impacted by river flooding as well. The McGregor map,
Community-Panel Numbers CID number, is 195183, was made effective January
19, 1972.
Flash floods are the number 1 weather-related killer in the United States. They
can quickly inundate areas thought not to be flood-prone. Iowa ranked number 1
in the United States for average annual flood damage for 1983 through 1997.
Much of this damage occurred in losses from the floods of 1993, but smaller-scale
floods are a regular occurrence in this state. According to national flood damage
reports, from 1997 through 2001, Iowa has had over $331 million dollars in
damages from flooding. A portion of this figure is covered by insurance, but
much is not. Public assistance programs also cover a portion of these damages
under a Presidential Declaration of Major Disaster, but apply only to certain
eligible damages. Flash flooding impacts include potential loss of life; property
damage and destruction; damage and disruption of communications,
transportation, electric service, and community services; crop and livestock
damage and loss and interruption of business. Hazards of fire, health and
transportation accidents, and contamination of water supplies are likely effects of
flash flooding situations. Associated with the 643 flash flooding events since
1993, there have been 4 deaths and 8 injuries in Iowa. Hazards of fire, health and

flash flooding situations as well.
Speed of

For the July 17, 2007 Flash Flood the National Climatic Data Center documents
$1.3 million in property damages to the City of McGregor.
Flash floods are somewhat unpredictable, but there are factors that can point to
the likelihood of a flood’s occurring in the area. Flash floods occur within a few
minutes or hours of excessive rainfall, a dam or levee failure, or a sudden release
of water held by an ice jam. Warnings may not always be possible for these
sudden flash floods. Predictability of flash floods depends primarily on the
data available on the causal rain. Individual basins react differently to
precipitation events. Weather surveillance radar is being used to improve
monitoring capabilities of intense rainfall. Knowledge of the watershed
characteristics, modeling, monitoring, and warning systems increase the
predictability of flash floods. Depending on the location in the watershed,
warning times can be increased. The National Weather Service forecasts the
height of flood crests, the data, and time the flow is expected to occur at a
particular location.
The Clayton County EMA monitors potential flood severity by using reports and
warnings issued by the National Weather Service. The county EMA and Clayton
County Sheriff’s office dispatch center notifies Clayton County emergency
responders in the event that flooding may affect or is affecting the county.
The City of McGregor monitors the level of the Mississippi River at the US
Geological Survey Station on the river. The gauge and river level is monitored
closely when flood conditions prevail.

River Flood
Definition
Description
A rising or overflowing of a tributary or body of water that covers adjacent land not
usually covered by water when the volume of water in a stream exceeds the channel’s
capacity.
Floods are the most common and widespread of all natural disasters, except fire. Most
communities in the United States can experience some kind of flooding after spring
rains, heavy thunderstorms, winter snow thaws, waterway obstructions, or levee or
dam failures. Often it is a combination of these elements that causes damaging floods.
Floodwaters can be extremely dangerous. The force of six inches of swiftly moving
water can knock people off their feet and two feet of water can float a car. Floods can be
slow-, or fast-rising but generally develop over a period of days. Flooding is a natural
and expected phenomenon that occurs annually, usually restricted to specific streams,
rivers or watershed areas.
The Floods of 1993 are still fresh in the minds of many Iowans. Flooding has been
a regular and frequent hazard in Iowa. Since 1993, here have been 2,473 river
flooding events in Iowa according to the National Climatic Data Center. Iowa has
been involved in 13 Presidential Declarations of a major disaster related to
flooding since 1990.
For the City of McGregor, river floods represent both the most frequent and most
devastating natural disaster. The City of McGregor is located in a low lying area
of the Mississippi River Basin in northeast Iowa. The Mississippi River borders
the city and is fed by a watershed that encompasses 65,810 square miles.
Flood stage for the Mississippi River as measured by a US Geological Service
Station in McGregor begins at 18 feet. Since 1993 there have been 3 documented
river flood events that have impacted the City of McGregor. The all time high

Given the history of this hazard it is likely that there will be many minor events
each year in Iowa and a high likelihood that a major flooding event requiring
federal assistance will occur in the next 5 years. While hundreds of homes and
businesses have been removed from the floodplains in the State of Iowa over the
last decade, there are many in the state remaining to be removed in areas that
have a probability of flooding.
With the City of McGregor’s history of flooding problems and disasters, it is
inevitable the city will witness more floods in the future, some of which may
cause damage.
The vulnerability from flooding is quite delineated. Much work in the area of
flood hazard mapping has allowed many communities to restrict development in
hazardous areas.
In the City of McGregor the most vulnerable areas are properties on low lying
ground adjacent to the Mississippi River. People most vulnerable in these areas
are those who do not have access to early warning capabilities such as are
available through siren systems or NOAA Weather Radio.
The City of McGregor has 103 structures that are located within the 100-year
flood plain. These structures include 54 classified as residential and 49 others
including commercial, storage and public or municipal facilities. Among the
public facilities in the flood plain are: McGregor Municipal Utilities; McGregor
Sewage Treatment Plant; Well No. 6; McGregor City Hall; McGregor Fire Station;
McGregor Public Library; McGregor Museum and the Riverfront Park Shelter
House. Total value of all these structures from records provided by the City of

Severe Winter Storm
Definition
Severe winter weather conditions that affect day-to-day activities. These can include
blizzard conditions, heavy snow, blowing snow, freezing rain, heavy sleet, and extreme
cold.
Description
Winter storms are common during the winter months of October through April. The various
types of extreme winter weather cause considerable damage. Heavy snows cause immobilized
transportation systems, downed trees and power lines, collapsed buildings, and loss of livestock
and wildlife. Blizzard conditions are winter storms which last at least three hours with sustained
wind speeds of 35 mph or more, reduced visibility of 1/4 mile or less, and white-out conditions.
Heavy snows of more than six inches in a 12-hour period or freezing rain greater than 1/4 inch
accumulation causing hazardous conditions in the community can slow or stop the flow of vital
supplies as well as disrupting emergency and medical services. Loose snow begins to drift when
the wind speed reaches 9 to 10 mph under freezing conditions. The potential for some drifting is
substantially higher in open country than in urban areas where buildings, trees, and other
features obstruct the wind. Ice storms result in fallen trees, broken tree limbs, downed power
lines and utility poles, fallen communications towers, and impassable transportation routes.
Severe ice storms have caused total electric power losses over large areas of Iowa and rendered
assistance unavailable to those in need due to impassable roads. Frigid temperatures and wind
chills are dangerous to people, particularly the elderly and the very young. Dangers include
frostbite or hypothermia. Water pipes, livestock, fish and wildlife, and pets are also at risk from
extreme cold and severe winter weather.
Historical
Occurrence
Probability
Vulnerability
Since 1993, Iowa has had 3,636 heavy snow, ice storm, or extreme wind-chill
events. The City of McGregor has been impacted by a number of these events. In
a normal year the county experiences at least one severe winter weather event,
and in many years more than one severe winter storm. There are many accounts
of large numbers of deaths due to cold and blizzards in Iowa's history, but none
recorded in the history of the City of McGregor. While we are not as vulnerable
as the early settlers, there are recent accounts of multiple deaths from snowstorms
and extreme cold around the state. Three Presidential Declarations of Major
Disaster have been declared in Iowa since 1990 for severe winter storms, the most
recent in February, 2007. Since January 11, 1993, National Climatic Data Center
records indicate 54 winter storm events that have affected the McGregor area.
Winter storms regularly move easterly and use both the southward plunge of
arctic cold air from Canada and the northward flow of moisture from the Gulf of
Mexico to produce heavy snow and sometimes blizzard conditions in Iowa and
other parts of the Midwest. From 1983 to 1998, Des Moines averaged nearly 50
days a year with falling snow. The cold temperatures, strong winds, and heavy
precipitation are the ingredients of winter storms. Most areas of the state,
including the City of McGregor, can usually expect 2 or 3 winter storms a season
with an extreme storm every 3 to 5 years on average (more in the northwest,
fewer in the southeast). A snowfall of six inches or more from one storm only
occurs in 49% of Iowa winters, while a large winter storm event of 10 inches or
more will occur about once every 3 years. In 2008, all of Iowa experienced one of
its worst winters ever with record and near record snowfalls recorded across the
state of Iowa. Dubuque, Iowa, 60 miles from McGregor posted a record snowfall
of 78.7 inches for the winter of 2007-2008.
Due to the historical frequency of severe winter storms and the City of
McGregor’s geographical location, it is a near 100 percent certainty the city will be
regularly—perhaps annually-- impacted by winter storms in the future.
Hazardous driving conditions due to snow and ice on highways and bridges lead
to many traffic accidents. The leading cause of death during winter storms is
transportation accidents. About 70% of winter-related deaths occur in
automobiles and about 25% are people caught out in the storm. The majority of
these are males over 40 years of age. Emergency services such as police, fire, and
ambulance are unable to respond due to road conditions. Emergency needs of

remote or isolated residents for food or fuel, as well as for feed, water and shelter
for livestock are unable to be met. People, pets, and livestock are also susceptible
to frostbite and hypothermia during winter storms. Those at risk in McGregor
are primarily either engaged in outdoor activity (shoveling snow, digging out
vehicles, or assisting stranded motorists), or are the elderly or very young. The
Central Community School District in McGregor often closes during extreme cold
or heavy snow conditions to protect the safety of children and bus drivers.
Citizens' use of kerosene heaters and other alternative forms of heating may
create other hazards such as structural fires and carbon monoxide poisoning.
Winter storms are quite vast and would likely impact multiple counties. Certain
areas may experience local variations in storm intensity and quantity of snow or
ice. The City of McGregor Public Works Department is responsible for the
removal of snow and treatment of snow and ice with sand and salt on the 12
miles of streets in the city. The entire City of McGregor would be affected by a
severe winter storm.
Immobilized transportation (including emergency vehicles), downed trees and
electrical wires, building and communication tower collapse, and bodily
injury/death are just a few of the impacts of a severe winter storm. Vehicle
batteries and diesel engines are stressed and the fuel often gels in extreme cold
weather. This impacts transportation, trucking, and rail traffic. Rivers and lakes
freeze and subsequent ice jams threaten bridges and can close major highways.
Ice jams can also create flooding problems when temperatures begin to rise. An
ice coating at least one-fourth inch in thickness is heavy enough to damage trees,
overhead wires, and similar objects and to produce widespread power outages.
Buried water pipes can burst causing massive ice problems, loss of water and
subsequent evacuations during sub-zero temperatures. Fire during winter storms
presents a great danger because water supplies may freeze, and firefighting
equipment may not function effectively or personnel and equipment may be
unable to get to the fire. If power is out, interiors of homes become very cold,
causing pipes to freeze and possibly burst. Cold temperature impacts on
agriculture are frequently discussed in terms of frost and freeze impacts early or
late in growing seasons and on unprotected livestock. The cost of snow removal,
repairing damage, and loss of business can have large economic impacts on the
community. Since 1993, Iowa has had 22 injuries related to winter storms and 12
deaths.
The City of McGregor has had no recorded death attributed to a winter storm. A
winter storm would normally impact the entire City of McGregor. Research
efforts could not determine any estimates of damages to the City of McGregor
due to severe winter storms.
The National Weather Service (NWS) has developed effective weather advisories
that are promptly and widely distributed. Radio, TV, and Weather Alert Radios
provide the most immediate means to do this. Accurate information is made
available to public officials and the public up to days in advance. Several
Speed of
notifications made by the National Weather Service include winter storm watch,

winter storm warning, blizzard warning, winter weather advisory, and a
frost/freeze advisory. The Clayton County Emergency Management Agency and
Clayton County Sheriff’s office dispatch center notifies the county’s emergency
responders of all weather warnings, including severe winter storms.

Thunderstorms and Lightning
Definition
Description
Historical
Occurrence
Probability
Atmospheric imbalance and turbulence resulting in heavy rains, winds reaching or
exceeding 58 mph; tornadoes or surface hail at least 0.75 inches in diameter. Can include
a hailstorm which is characterized be balls or irregularly shaped lumps of ice greater
than 0.75 inches in diameter fall with rain.
Thunderstorms are common in Iowa and can occur singly, in clusters, or in lines. They
are formed from a combination of moisture, rapidly raising warm air, and a lifting
mechanism such as clashing warm and cold air masses. Most thunderstorms produce
only thunder, lightning, and rain. Severe storms however, can produce tornadoes, high
straight-line winds above 58 mph, microbursts, lightning, hailstorms, and flooding. The
NWS considers a thunderstorm severe if it produces hail at least 3/4-inch in diameter,
wind 58 mph or higher, or tornadoes. High straight-line winds, which can often exceed
60 mph, are common occurrences and are often mistaken for tornadoes. Lightning is an
electrical discharge that results from the buildup of positive and negative charges
within a thunderstorm. When the buildup becomes strong enough, lightning appears
as a “bolt.” This flash of light usually occurs within the clouds or between the clouds
and the ground. A bolt of lightning reaches temperatures approaching 50,000 degrees F
in a split second. This rapid heating, expansion, and cooling of air near the lightning
bolt creates thunder.
At least 7,946 severe thunderstorm events have impacted Iowa since 1993. The
City of McGregor has been impacted by a number of these events. Because
thunderstorms may occur singly, in clusters, or in lines, it is possible that several
thunderstorms may affect the area in the course of a few hours. It is likely that
more than the 7,946 individual severe storms systems occurred in the county.
One system may spawn multiple events. A number of these thunderstorms have
9
caused other hazards such as flash flooding, river flooding, and tornadoes.
There have been three Presidential Declarations of Major Disasters since 1990
related to Severe Storms. National Climatic Data Center Records indicate that
since 5/23/1994, 6 severe thunderstorm events have been recorded as impacting
the City of McGregor.
Iowa, experiences between 30 and 50 thunderstorm days per year on average.
Clayton County and the City of McGregor are impacted by these events also.
With Iowa's location in the interior of the U.S., there is a very high likelihood that
a few of these summer storms will become severe and cause damage. Because of
the humid continental climate that Iowa experiences, ingredients of a severe
thunderstorms are usually available (moisture to form clouds and rain, relatively
9
warm and unstable air that can rise rapidly, and weather fronts and convective
systems that lift air masses).
Due to the historical frequency of severe winter storms and the City of
McGregor’s geographical location, it is a near 100 percent certainty the city will be
impacted by thunderstorms and lightning in the future.
Vulnerability
Those in unprotected areas, mobile homes, or automobiles during a storm are at risk.
Sudden strong winds often accompany a severe thunderstorm and may blow down trees
across roads and power lines. Lightning presents the greatest immediate danger to people
and livestock during a thunderstorm. It is the second most frequent weather-related killer
in the U.S. with nearly 100 deaths and 500 injuries each year. (Floods and flash floods are
the number one cause of weather related deaths in the U.S.) Livestock and people who are
outdoors, especially under a tree or other natural lightning rods, in or on water, or on or
near hilltops are at risk from lightning. Hail can be very dangerous to people, pets, and
livestock if shelter is not available. Flash floods and tornadoes can develop during
thunderstorms as well. People who are in automobiles or along low-lying areas when
flash flooding occurs and people who are in mobile homes are vulnerable to the impacts of
severe thunderstorms. Every resident and structure in the City of McGregor is vulnerable
to the affect of thunderstorms and lightning.

Severe thunderstorms can be quite expansive with areas of localized severe
conditions. Most severe thunderstorm cells are 5 to 25 miles wide with a larger
area of heavy rain and strong winds around the main cell. Most non-severe
thunderstorms have a lifespan of 20 to 30 minutes, while severe thunderstorms
last longer than 30 minutes. A lightning strike would most likely affect only a
single structure or person whereas a thunderstorm would affect the entire City of
McGregor.
Like tornadoes, thunderstorms and lightning can cause death, serious injury, and
substantial property damage. Severe thunderstorms can bring a variety of
associated hazards with them including straight-line winds in excess of 100 mph.
Straight-line winds are responsible for most thunderstorm damage. High winds
can damage trees, homes (especially mobile homes), and businesses and can
knock vehicles off of the road. The power of lightning's electrical charge and
intense heat can electrocute people and livestock on contact, split trees, ignite
fires, and cause electrical failures. Thunderstorms can also bring large hail that
can damage homes and businesses, break glass, destroy vehicles, and cause
bodily injury to people, pets, and livestock. One or more severe thunderstorms
occurring over a short period (especially on saturated ground) can lead to
flooding and cause extensive power and communication outages as well as
agricultural damage. Damages caused by thunderstorms and would likely impact
the entire City of McGregor. Lightning damage would be more localized.
National Climatic Data Center records indicate a total of $77,000 in property
damage with no deaths or injuries as having occurred due to the six severe
thunderstorm events impacting the city of McGregor since 5/23/1994.
Some thunderstorms can be seen approaching, while others hit without warning.
The National Weather Service issues severe thunderstorm watches and warnings
as well as statements about severe weather and localized storms. These messages
are broadcast over NOAA Weather Alert Radios and area TV and radio stations.
Advances in weather prediction and surveillance have increased warning times.
The resolutions of radar and Doppler radar have increased the accuracy of storm
location and direction. Weather forecasting and severe weather warnings issued
by the National Weather Service usually provide residents and visitors alike
adequate time to prepare. Isolated problems arise when warnings are ignored.
The Clayton County Sheriff’s office dispatch center notifies the county’s
emergency responders of all weather warnings, including severe thunderstorms.

Historical
Occurrence
Probability
Vulnerability
A violent, destructive, rotating column of air taking the shape of a funnel-shaped cloud
that progresses in a narrow, erratic path. Rotating wind speeds can exceed 200 mph
and travel across the ground at average speeds of 25 to 30 mph.
A tornado is a violent whirling wind characteristically accompanied by a funnel shaped
cloud extending down from a cumulonimbus cloud. A tornado can be a few yards to
about a mile wide where it touches the ground. An average tornado, however, is a few
hundred yards wide. It can move over land for distances ranging from short hops to
many miles, causing great damage wherever it descends. The funnel is made visible by
the dust sucked up and by condensation of water droplets in the center of the funnel.
The rating scale used to rate tornado intensity is called the Fujita Scale (See page 65).
In the U.S., Iowa is ranked third in the number of strong-violent (EF2-EF5)
tornadoes per 10,000 square miles. From 1950-1995, Iowa averaged 31 twisters
per year. In Iowa most tornadoes occur in the spring and summer months, but
twisters can and have occurred in every month of the year. Late afternoon to
evening hour tornadoes are the most common, but they can occur at any time of
the day.
There have been 12 recorded incidents of a direct hit to Clayton County by a
tornado since May 10, 1953. On May 30, 1985 an EF3 tornado touched down
west of Elkader. It hit the Clayton County Care Facility and killed two residents
and injured another 25. Twenty farmsteads were struck. Total damage was
estimated at $25 million, with $1.5 million occurring at the County Care Facility.
No specific incident of a tornado directly striking the City of McGregor could be
found in any records. McGregor Hazard Mitigation Planning Committee
members did recount, however, past incidents when reputed tornadoes or
tornado like winds caused minor damage to the city or the immediate area.
Historically, 30-40 tornadoes are confirmed in Iowa per year. Developed areas
occupy a growing portion of Iowa and stand a likely chance of having a tornado
occur in the next ten years. Included in these statistics are Clayton County and the
City of McGregor. Diagram 65 shows the tornado risk areas for the United States.
Those most at risk from tornadoes include people living in mobile homes,
campgrounds, and other dwellings without secure foundations or basements.
People in automobiles are also very vulnerable to twisters. The elderly, very
young, and the physically and mentally handicapped are most vulnerable
because of the lack of mobility to escape the path of destruction. People who may
not understand watches and warnings due to language barriers are also at risk.
People most at risk are also those who do not have access to early warning
capabilities such as are available through siren systems or NOAA Weather Radio.

Generally the destructive path of a tornado is only a couple hundred feet in
width, but stronger tornadoes can leave a path of devastation up to a mile wide.
Normally a tornado will stay on the ground for no more than 20 minutes;
however, one tornado can touch ground several times in different areas. Large
hail, strong straight-line winds, heavy rains, flash flooding, and lightning are also
associated with severe storms and may cause significant damage to a wider area.
It is feasible that a tornado of EF4 magnitude or larger could destroy the entire
City of McGregor.
The severity of damage from tornadoes can be very high. Impacts can range from
broken tree branches, shingle damage to roofs, and some broken windows; all the
way to complete destruction and disintegration of well constructed structures,
infrastructure, and trees. Injury or death related to tornadoes most often occurs
when buildings collapse; people are hit by flying objects or are caught trying to
escape the tornado in a vehicle. Since 1950, Iowa has had 1,831 injuries related to
tornadoes and 61 deaths over the same time period.

The Elkader area incurred two deaths, 25 injuries and $25 million in property
damages due to the tornado that touched down near on May 30, 1985.
Historically, since May 10, 1953, Clayton County has been hit by 12 reported
tornadoes. Total deaths in this time period were 2; injuries, 26; property damage,
$26.133 million and crop damages, $5 million.
Tornadoes strike with an incredible velocity. Wind speeds may approach 300
miles per hour and the storm can travel across the ground at more than 70 mph.
These winds can uproot trees and structures and turn harmless objects into
deadly missiles, all in a matter of seconds. Advancements in weather forecasting
have allowed watches to be delivered to those in the path of these storms up to
hours in advance. The best lead-time for a specific severe storm and tornado is
about 30 minutes. Tornadoes have been known to change paths very rapidly,
thus limiting the time in which to take shelter. Tornadoes may not be visible on
the ground due to blowing dust or driving rain and hail.

High speed winds of 50 mph or higher, often associated with severe winter storms,
severe thunderstorms, downbursts and very steep pressure gradients usually
accompanying frontal systems.
Extreme winds other than tornados are experienced in all regions of the United States.
It is difficult to separate the various wind components that cause damage from other
wind-related natural events that often occur with or generate windstorms.
Large-scale extreme wind phenomena are experienced over every region of the
United States. Historically, high wind events are associated with severe
thunderstorms and blizzards. It is often difficult to separate windstorms and
tornado damage when winds get above 70 knots. There have been 357 wind
events in Iowa since 1950 in which wind speeds have exceeded 70 knots (80.5
9
mph).
National Climatic Data Center statistics document 116 high wind events in
Clayton County Between 1950 and 2007. Six of these events are recorded as
affecting the City of McGregor on 5/23/1994; 7/19/1994; 8/19/1994; 6/15/1997;
4/11/2001 and 7/20/2006
Based on historical averages, Iowa would expect to have about 7 to 10 wind
events each year in which wind speeds exceed 70 knots (80.5 mph). It is a
certainty given the geographical location of the City of McGregor that the city
will be impacted by a windstorm or severe wind at least once every three years, if
not more frequently. The diagram on page 66 shows wind zones for the United
States.
Those most at risk from windstorms include people living in mobile homes,
campgrounds, parks, and other dwellings without secure foundations or
basements. People in automobiles are also very vulnerable to wind storms. The
elderly, very young, and the physically and mentally handicapped are most
vulnerable because of the lack of mobility to escape the path of destruction.
People who may not understand watches and warnings due to language barriers
are also at risk.
Unlike tornadoes, windstorms may have a destructive path that is tens of miles
wide. Large hail, strong straight-line winds, heavy rains, flash flooding, and
lightning are also associated with severe storms and may cause significant
damage to a wider area. A windstorm will affect the entire City of McGregor.
The severity of damage from windstorms can be very high. Impacts can range
from broken tree branches, shingle damage to roofs, and some broken windows,
all the way to complete destruction and disintegration of well-constructed
structures, infrastructure, and trees. Injury or death related to windstorms most
often occurs when buildings collapse, people are hit by flying objects or are
caught trying to escape the windstorm in a vehicle. Crop damage is often
associated with windstorms, laying down crops, breaking stalks, and twisting
plants, reducing the yield and making it difficult to harvest. Damages caused by
windstorms and severe winds would likely impact the entire City of McGregor.

Emergency 911, law enforcement, fire, emergency medical services, public works, and emergency
warning systems are just a few of the vital services which rely on communication systems to
effectively protect citizens. Business and industry rely heavily on various communication media
as well. Mechanical failure, traffic accidents, power failure, line severance, and weather can affect
communication systems and disrupt service. Disruptions and failures can range from localized
and temporary to widespread and long-term. If switching stations are affected, outage could be
more widespread.
No widespread communications failures have occurred in Iowa. In the City of

Dam Failure
Definition
Description
Historical
Occurrence
A break in, or imposed threat from, any water retention fixture which may endanger
population downstream of the containment area.
Dams are constructed for a variety of uses, including flood control, erosion control,
water supply impoundment, hydroelectric power generation, and recreation. Flooding,
operating error, poor construction, lack of maintenance, damage due to burrowing
animals, vandalism, terrorism, and earthquakes can cause dam failure. Dams are
classified into three categories based on the potential risk to people and property should
a failure occur: High Hazard - If the dam was to fail, lives would be lost and extensive
property damage could result; Moderate Hazard - Failure could result in loss of life and
significant property damage; and Low Hazard - Failure results in minimal property
damage only. The classification may change over time because of development
downstream from the dam since its construction. Older dams may not have been built
to the standards of its new classification. Dam hazard potential classifications have
nothing to do with the material condition of a dam, only the potential for death or
destruction due to the size of the dam, the size of the impoundment, and the
characteristics of the area downstream of the dam. The Iowa Department of Natural
Resources tracks all dams in the state of Iowa with a height of at least 25 feet or a total
storage of at least 50 acre feet of water. The inventory excludes all dams less than 6 feet
high regardless of storage capacity and dams less than 15 acre feet of storage regardless
of height.
Between 1960 and 1997, there have been at least 23 dam failures causing one or
more fatalities (318 deaths total) in the U.S. There have been no documented dam
failures in Iowa that resulted in death or severe property damage. There was
concern during the very wet period of 1993 that water would overtop Saylorville
1
Reservoir. With the outfall flowing at full capacity and water flowing out the
spillway, the reservoir did not overtop the dam.
In Clayton County and specifically the City of McGregor, there has been no
historical occurrence of dam failure.
With increased attention to sound design, quality construction, and continued
maintenance and inspection, dam failure probability can be reduced. It is
important to consider that by 2020, 85% of the dams in the United States will be
more than 50 years old (the design life of a dam).
Probability
Vulnerability
According to the National Performance of Dams Website two flood control dams,
the Pikes Peak Flood Control Dam and Siegele Flood Control Dam, designed to
protect the City of McGregor from flooding, are listed as high risk dams. These
dams were built in 1938. Local officials and the Clayton County Emergency
Management Agency state that neither of these dams, even during the worst
flooding that has occurred in the 69 years since their construction, has ever
approached the stage where water was flowing over the spillway.
People and property along streams are most vulnerable. Facilities and lives
considerable distances from the actual impoundment are not immune from the
hazard. Depending on the size and volume of the impoundment as well as the
channel characteristics, a flash flood can travel a significant distance.
Clayton County Emergency Management has determined that there are 15
residence and property locations in the unincorporated area of the county in
addition to the City of McGregor that could be impacted by a failure of either or
both of the Pikes Peak or Siegele Flood Control Dams. Appendix 8, page 206
provides a map detailing the Dam Overflow Basins of the Pikes Peak and Siegele
Flood Control Dams.

The area impacted following a dam failure would be limited to those areas in and
near the floodplain. People and property outside the floodplain could also be
impacted depending on the proximity to the dam and the height above the
normal stream level.
Maximum
Extent
Should either of the Siegele of Pikes Peak Flood Control Dams fail, the maximum
extent of damage would encompass 15 residence and property locations in the
unincorporated area of the county and potentially portions of the flood plain area
in the City of McGregor. Appendix 8, page 206 provides a map detailing the Dam
Overflow Basins of the Pikes Peak and Siegele Flood Control Dams.
There are 2,442 inventoried dams located in Iowa. Of these 63 are high hazard,
160 are categorized as significant hazard, and 2,219 are classified as low-hazard
dams. The severity of damage could range from property damage, if a small
subdivision impoundment failed, all the way to multiple deaths, injuries, and
extensive property damage if a large high-hazard dam, such as the Saylorville
Reservoir, failed upstream from Des Moines.

For the Pikes Peak and Siegele Flood Control Dams, damage would be limited to
the 15 residence and property locations in the unincorporated area of the county
and potentially 103 structures located in the flood plain area of the City of
McGregor. The Main Street Valley Profile Study conducted by Vierbacher
Engineering from Madison, Wisconsin during the summer of 2007 was
inconclusive as to what affect flooding would have on the City of McGregor.
A dam failure can be immediate and catastrophic leaving little or no time to warn
those downstream of the imminent hazard. With maintenance and monitoring,
weak areas and possible failure points can be identified allowing time for
evacuation and securing of the dam. Most dams are only inspected periodically
thus allowing problems to go undetected until a failure occurs. The Pikes Peak
and Siegele Dams in Clayton County are inspected by the Iowa DNR every three
years.
With Clayton County’s history of flood experiences, potential flood situations are
monitored closely. Any extreme rainfalls and the potential affect it could have on
the Siegele or Pikes Peak Flood Control Dams will be monitored closely. Local
officials would make every effort to make certain that residents and property
owners likely to be affected by an event such as a dam breach would receive
several hours of pre-notification.

Levee Failure
Definition
Description
Historical
Occurrence
Probability
Vulnerability
Loss of structural integrity of a wall, dike, berm, or elevated soil by erosion, piping,
saturation, or under seepage causing water to inundate normally dry areas.
Levees constructed of compacted clay with a high plasticity tend to crack during cycles
of long dry spells. During heavy rainfalls that follow the dry spells, water fills the cracks
and fissures. In addition to increasing the hydrostatic forces, the water is slowly
absorbed by the clay. The effect of the absorbed water is an increase in the unit weight
of the clay as well as a decrease in its shear strength. This results in a simultaneous
increase of the slide (driving) forces and a decrease of the resisting (shear strength)
forces. Furthermore, the cyclic shrink/swell behavior of the cracked clay zone results in
a progressive reduction of the shear strength of the clay, perhaps approaching its
residual strength. It also results in deepening of the cracked clay zone, which may
eventually reach a depth of 9 ft (2.74 m) or more, especially for clays with a plasticity
index greater than 40. The end result may be a sloughing failure following a heavy
rainfall. It is believed that fast removal of the runoff water from the interconnected
network of cracks could alleviate this surface instability problem.
The levee of concern to the City of McGregor is a 1,500 feet long dirt levee built by the
US Army Corps of Engineers in 1969 across the face of the town, paralleling Front
Street. The levee is part of the Rock Island District levee system.
The Flood of 1993 was so great that the limits of many levees were tested and
sometimes exceeded. Of 275 Corps of Engineers levees affected by the flood, 85%
held, but 31 were overtopped, 8 were eroded and ruptured, and 3 were breached.
The performance of nonfederal levees was much worse: only 43% withstood the
1
trauma, and 800 of 1,400 failed. During the Midwest floods in June of 2008, 13
levees that are part of the Rock Island District were overtopped or breached. The
McGregor levee was not one of those overtopped or breached in 1993 or 2008.
The rate of failure of a levee or floodwall is difficult to predict, and sudden failure
is a possibility. Proper design and construction can limit the probability of a
levee failure. Development in the watershed can raise flood levels and make a
levee designed and constructed under previous characteristics inadequate for
3
current runoff conditions. While the McGregor levee has never overtopped or
breached, settling of the levee which is thought to be as much as a foot to one and
a half feet since its construction is providing concern that such an event could
occur.
People, property, and utilities in the floodplain are most at risk. Levees and
floodwalls give a false sense of security. People feel that levees will protect them
and their property against any future flooding. While this is usually true, the
hazard is only temporarily contained.
There are 103 structures in the City of McGregor flood plain that have the
potential for being impacted by a failure of the McGregor Levee. Of these, 54 are
classified as residential and 49 others are classified as commercial, storage and
public or municipal facilities. Among the public facilities in the flood plain are:
McGregor Municipal Utilities; McGregor Sewage Treatment Plant; Well No. 6;
McGregor City Hall; McGregor Fire Station; McGregor Public Library; McGregor
Museum and the Riverfront Park Shelter House. Total value of all these structures
from records provided by the City of McGregor in September, 2008 is estimated
at $11,862,723. Using an average of 2.34 people per household, the potential
number of people who could be affected is 126, or 15 percent of the McGregor
population.

Floodwaters breaching a levee are usually contained in the historic floodplain.
Interestingly enough, levee failure in one area may prevent flooding in another
area. A levee breach or overtopping occurring along one segment may drop the
level of water along other segments of the stream. For initial overtopping, the
overriding concern is choosing the least hazardous location for initial inundation
of the interior. The least hazardous location could be a golf course, an oxbow
lake, a ponding area, undeveloped area such as agricultural land, or a
downstream reach. A total of 103 structures in the City of McGregor flood plain
that have the potential for being impacted by a failure of the McGregor Levee. Of
these, 54 classified as residential and 49 others are classified as commercial,
storage and public or municipal facilities. This comprises 22 percent of the total
structures in the City of McGregor.
Water bursting through a narrow levee breach is moving much faster than the
floodwaters in the main channel. The breaking out of this front of water and its
fast flow can cause more destruction to structures behind the levee than
floodwaters in the main channel would have caused. A failed levee continues to
cause damage long after it breaks. The breach allows large volumes of water to
enter formerly dry areas, forming temporary lakes. Such lakes do not go away
immediately, because the lake is blocked from returning to the main channel by
levee segments that were not destroyed. Consequently, the water level drops
along the main river days before it drops behind breached levees. Often, pumps
behind the levees are needed to remove floodwaters that breach the levees. This
alleviates some of the impacts associated with levee failures. Sudden failure in an
urban setting could cause a catastrophe. In an urban setting the severity and
duration may be important for health reasons, but in an agricultural area for
economic reasons. Impacts would be similar to those experienced during a river
or flash flood. In the City of McGregor the 103 residential, commercial and
governmental structures in the flood plain would incur damage in the event of a
levee failure. In addition, all of residents of the City of McGregor could incur a
loss of necessary services due to infrastructure damage to municipal facilities.
The amount of warning time depends on the type of levee failure. Local flood
warning systems can help in determining the maximum water surface and the
timing of a flood situation. Hours or days of warning may be available for high
water that may overtop levees, but this does not provide complete security from a
rupture in the levee itself. A sudden failure of a portion of the levee may send
floodwaters gushing from this break within seconds. Normally, occupants of the
floodplain can be warned about potential levee breaches or breaks when high
water encroaches upon the levee.
With Clayton County’s history of flood experiences, potential flood situations are
monitored closely. Local officials would make every effort to make certain that
residents and property owners likely to be affected by an event such as a levee
failure would receive several hours of pre-notification.

Fixed Facility Hazardous Materials Incident
Definition
Description
Historical
Occurrence
Accidental release of chemical substances or mixtures that presents danger to the public
health or safety during production or handling at a fixed facility.
A hazardous substance is one that may cause damage to persons, property, or the
environment when released to soil, water, or air. Chemicals are manufactured and used
in ever increasing types and quantities. As many as 500,000 products pose physical or
health hazards and can be defined as “hazardous chemicals.” Each year, over 1,000 new
synthetic chemicals are introduced. Hazardous substances are categorized as toxic,
corrosive, flammable, irritant, or explosive. Hazardous materials incidents generally
affect a localized area and the use of planning and zoning can minimize the area of
impact.
During the period 1998-2001, Hazardous Materials Teams responded to 844 calls
at fixed facilities according to the Iowa Department of Public Health HSEES
system. Fixed facility releases accounted for about 71% of total releases. (Note:
the number of responses to drug-related operations has also risen sharply in the
state.)
2
In the City of McGregor, Iowa DNR records show that between the years 1995
and 2006 there was 1 minor incident involving a spill of hazardous materials into
the Mississippi River from a fixed facility.
There are 2,728 sites in Iowa that, because of the volume or toxicity of the
materials on site, are designated as Tier Two facilities under the Superfund
Amendments and Reauthorization Act. Despite increasing safeguards, more and
more potentially hazardous materials are being used in commercial, agricultural,
and domestic activities.
Probability
Vulnerability
The City of McGregor has 2 facilities that are EPA regulated due to the hazardous
materials used in processes associated with the facility or that is stored at the
facility. These facilities are the McGregor Municipal Utility and Agri-Bunge.
There are 8 additional facilities or businesses in the City of McGregor that have
hazardous materials on hand, providing more possibilities of a fixed hazardous
materials incident. Given the presence of these facilities it is probable there will be
future fixed facility hazardous materials incidents in the City of McGregor.
A hazardous materials accident can occur almost anywhere, so any area is
considered vulnerable to an accident. People, pets, livestock, and vegetation in
close proximity to facilities producing, storing, or transporting hazardous
substances are at higher risk. Populations downstream, downwind, and downhill
of a released substance are particularly vulnerable. Depending on the
characteristics of the substance released, a larger area may be in danger from
explosion, absorption, injection, ingestion, or inhalation. Occupants of areas
previously contaminated by a persistent material may also be harmed either
directly or through consumption of contaminated food and water. Facilities are
required to have an off-site consequence plan that addresses the population of the
surrounding area. Responding personnel are required to be trained to HAZMAT
Operations Level to respond to the scene, and those personnel that come into
direct contact with the substances released are required to have HAZMAT
Technician level training.

The most vulnerable people in City of McGregor to injury or health affects from a
fixed facility hazardous materials incident are workers associated with hazardous
materials at the facilities and emergency responders and people living in close
proximity to fixed facilities having hazardous materials. Because of the wide
array of variables associated with a hazardous materials release, vulnerability

estimates are difficult to determine. Some releases may have virtually no affect,
while significant portions of the county could be affected in the case of an
anhydrous ammonia or LP gas leak.
Most of the hazardous materials incidents are localized and are quickly contained
or stabilized by the highly trained fire departments and hazardous materials
teams. Depending on the characteristic of the hazardous material or the volume
of product involved, the affected area can be as small as a room in a building or
as large as 5 square miles or more. Many times, additional regions outside the
immediately affected area are evacuated for precautionary reasons. More
widespread effects occur when the product contaminates the municipal water
supply or water system such as a river, lake, or aquifer.
A gas release such as anhydrous ammonia or LP could affect significant portions
of the City of McGregor. The release of a toxic hazardous material into the
Mississippi River could affect the river for its entire course through the county
and into neighboring counties. The unpredictable nature of hazardous materials
coupled with climatic and geographic variables and the unknown affects of
different hazardous materials reacting together creates a situation where the
maximum extent of damage from a hazardous material release is unpredictable.
Immediate dangers from hazardous materials include fires and explosion. The
release of some toxic gases may cause immediate death, disablement, or sickness
if absorbed through the skin, injected, ingested, or inhaled. Contaminated water
resources may be unsafe and unusable, depending on the amount of contaminant.
Some chemicals cause painful and damaging burns to skin if they come in direct
contact with your body. Contamination of air, ground, or water may result in
harm to fish, wildlife, livestock, and crops. The release of hazardous materials
into the environment may cause debilitation, disease, or birth defects over a long
period of time. Loss of livestock and crops may lead to economic hardships
within the community.

Records maintained and provided by the Iowa Department of Natural resources
regarding the only reported release of hazardous materials releases from a fixed
facility in City of McGregor do not mention any injuries. The records do not
mention any costs associated with cleanup or control of the chemicals or any costs
associated with damages caused by the chemicals.

Onset
When managed properly under regulations, hazardous materials pose little risk.
However, when handled improperly or in the event of an accident, hazardous materials
can pose a significant risk to the population. Hazardous materials incidents usually occur
very rapidly with little or no warning. Even if reported immediately, people in the area of
the release have very little time to be warned and evacuated. During some events,
sheltering in-place is the best alternative to evacuation because the material has already
affected the area and there is no time to evacuate safely. Public address systems,
television, radio and the NOAA Weather Alert Radios are used to disseminate emergency
messages about hazardous materials incidents.
7
The Clayton County Office of Emergency Management and Clayton County Sheriff’s office
dispatch center notifies applicable Clayton County emergency responders about
hazardous material incidents. Clayton County has an agreement with the Linn County
Hazardous Materials team for assistance at hazardous materials incidents. (See Diagram,

Accidental release of chemical substances or mixtures that presents danger to the public

A hazardous substance is one that may cause damage to persons, property, or the
environment when released to soil, water, or air. Chemicals are manufactured and used
in ever increasing types and quantities. As many as 500,000 products pose physical or
health hazards and can be defined as “hazardous chemicals.” Each year, over 1,000 new
synthetic chemicals are introduced and transported across the county via semi truck
and train. Hazardous substances are categorized as toxic, corrosive, flammable, irritant,
or explosive. Hazardous materials incidents generally affect a localized area, and the
use of planning and zoning can minimize the area of impact.
During the period 1998-2001, there where 346 transportation hazardous materials
incidents in Iowa. These were for a range of materials and varying severity.
According to information provided by the Iowa DNR, there have been 2 minor
transportation hazardous materials incidents in the McGregor area since 1995.
Both involved the spill of petroleum products and were cleaned up using local
resources. All were localized and none threatened any populated areas or caused
any evacuations.
Large quantities of hazardous materials are transported daily on Iowa streets,
highways, interstates, and railways. Roadways are a common site for the release
of hazardous materials. Railways are another source for hazardous materials
releases. The Department of Transportation regulates routes and speed limits
used by carriers and monitors types of hazardous materials crossing state lines.
Despite increasing safeguards, more and more potentially hazardous materials
are being used in commercial, agricultural, and domestic uses and are being
transported on Iowa roads and railways.

Given the historical occurrence of transportation hazardous materials incidents in
Clayton County and the highway system serving the City of McGregor and the
amount of hazardous materials passing through the city on a daily basis via semis
and other transports such as barges on the Mississippi River it is probable that
there will be transportation hazardous materials incidents occurring in the future.
A hazardous materials incident can occur almost anywhere, so any area is
considered vulnerable to an accident. People, pets, livestock, and vegetation in
close proximity to transportation corridors and populations downstream,
downwind, and downhill of a released substance are particularly vulnerable.
Depending on the characteristics of the substance released, a larger area may be
in danger from explosion, absorption, injection, ingestion, or inhalation.
Occupants of areas previously contaminated by a persistent material may also be
harmed either directly or through consumption of contaminated food and water.
Vulnerability
The City of McGregor is most vulnerable to experiencing a transportation
hazardous materials incident on US Highway 18 and State Highway 76 that serve
the city as well as from barge and other river traffic using the Mississippi River.
Property adjacent to these transportation routes is vulnerable to damage from a
hazardous materials release and people living or traveling near an incident are
vulnerable to physical harm from any release that may occur. Another area of
vulnerability is due to the Canadian Pacific Railroad which passes up to seven
trains a day through the City of McGregor. In 2008 the Canadian Pacific Railroad
had two significant incidents in Clayton County, one which resulted in a spill of
12,000 gallons of diesel fuel.

immediately affected area are evacuated for precautionary reasons. More
widespread effects occur when the product contaminates the municipal water
supply or water system such as a river, lake, or aquifer. For the City of McGregor
this means that a large release of hazardous materials in the right conditions
could affect large areas of the city, possibly even the entire city.
During the period 1993-2001, there where 68 injuries and 9 fatalities related to
transport of hazardous materials in Iowa. Many of these are related to the
collision itself rather than the product released. Immediate dangers from
hazardous materials include fires and explosions. The release of some toxic gases
may cause immediate death, disablement, or sickness if absorbed through the
skin, injected, ingested, or inhaled. Contaminated water resources may be unsafe
and unusable, depending on the amount of contaminant. Some chemicals cause
painful and damaging burns if they come in direct contact with skin.
Contamination of air, ground, or water may result in harm to fish, wildlife,
livestock, and crops. The release of hazardous materials into the environment
may cause debilitation, disease, or birth defects over a long period of time. Loss
of livestock and crops may lead to economic hardships within the community.
The occurrence of a hazmat incident many times shuts down transportation
corridors for hours at a time while the scene is stabilized, the product is offloaded, and reloaded on a replacement container.
Data provided by the Iowa Department of Natural Resources concerning the two
transportation hazardous materials releases that have occurred since 1995 near
the City of McGregor does not provide any information relative to costs
associated with cleaning up any of the spills or of any property damage that
occurred. The information does indicate there were injuries associated with one of
the incidents but the injuries were due to the accident, not the hazardous
materials involved.
When managed properly under current regulations, hazardous materials pose
little risk. However, when handled improperly or in the event of an accident,
hazardous materials can pose a significant risk to the population. Hazardous
materials incidents usually occur very rapidly with little or no warning. Even if

A single or multi-vehicle incident which requires responses exceeding normal day-today capabilities.
An extensive surface transportation network exists in Iowa. Local residents, travelers,
business, and industry rely on this network on a daily basis. Thousands of trips a day
are made on the streets, roads, highways, and interstates in the state. If the designed
capacity of the roadway is exceeded, the potential for a major highway incident
increases. Weather conditions play a major factor in the ability of traffic to flow safely
in and through the state as does the time of day (rush hour) and day of week. Incidents
involving buses and other high-occupancy vehicles could trigger a response that
exceeds the normal day-to-day capabilities of response agencies.
Numerous major and minor traffic accidents take place everyday in Iowa and
result in property damage and injury. Major accidents involving multiple
vehicles and serious injury unfortunately are not uncommon either. In the tenyear period from 1990 through 1999, there were a total of 714,322 total traffic
accidents. These resulted in 32,837 major injuries, 138,155 minor injuries, and
4,724 deaths.

Incident reports from the MarMac Rescue Squad document an average of 50
highway transportation incidents per year. In the past five years there have been
five fatalities associated with highway transportation incidents in the McGregor
area. The majority of these accidents are occurring on US Highway 18 and State
Highway 76.
Although traffic engineering, inspection of traffic facilities, land use management
of areas adjacent to roads and highways, and the readiness of local response
agencies have increased, highway incidents continue to occur. As the volume of
traffic on the state’s streets, highways, and interstates increases, the number of
traffic accidents will likely also increase. The combination of large numbers of
people on the road, unpredictable weather conditions, potential mechanical
problems, and human error always leaves open the potential for a transportation
accident.
Given the amount of traffic that travels US Highway 18 and State Highway 76
through McGregor; future traffic accidents are a 100 percent probability.
Considering past transportation fatalities in the McGregor area it is probable the
community will incur at least one highway transportation incident related fatality
every year.
Those who use the surface transportation system in the City of McGregor are
most vulnerable. Travelers, truckers, delivery personnel, and commuters are at
risk at all times that they are on the road. During rush hours and holidays the
number of people on the road in Iowa is significantly higher. This is also true
before and after major gatherings such as sporting events, concerts, and
conventions. Pedestrians and citizens of the City of McGregor are less vulnerable
but still not immune from the impacts of a highway incident. The hilly terrain
and curved roads in the McGregor area add to the vulnerability of transportation
accidents in the county.
Iowa is crisscrossed by thousands of miles of roads, highways, and interstates.
Highway incidents are usually contained to areas on the roadway or adjacent to
the roadway. Few highway incidents affect areas outside the traveled portion of
the road and the right-of-way. Extensive segments of the transportation system
can be impacted during significant weather events, such as a snowstorm, when
multiple separate accidents occur.

Severity
November, 2008
At its maximum extent in the City of McGregor a highway transportation
incident could involve multiple vehicles, including mass transit vehicles and have
multiple casualties, but it would still be localized in nature. Such a situation
would overwhelm the response capabilities of local emergency responders and
also the medical treatment capabilities of Prairie Du Chien and Clayton County
hospitals. The area of impact can extend beyond the localized area if the vehicle(s)
involved are transporting hazardous materials and could impact several square
miles.
Highway incidents threaten the health and lives of people in the vehicles,
pedestrians, and citizens of the community if hazardous materials are involved.
Mass casualty events can occur if mass transit vehicles are involved. Community
bus lines, metro transit buses, and school buses have a good safety record, but
accidents can and do occur. Numerous injuries are a very real possibility in
situations involving mass transit vehicles. Property damage would be limited to
vehicles and cargo involved; roads, bridges, and other infrastructure; utilities
such as light and power poles; and third-party property adjacent to the accident
scene such as buildings and yards. In the ten-year period from 1990 through
1999, there were a total of 714,322 total traffic accidents. These resulted in 32,837
major injuries, 138,155 minor injuries, and 4,724 deaths.
In Clayton County during the years of 2004-2006, the largest number of vehicles
involved in accidents was three and largest number of people injured in an
accident was five. In McGregor the maximum number of vehicles involved in a
highway transportation incident was two and the largest number of people
injured was three.

An extended interruption of electric, petroleum or natural gas service, which could
create a potential health problem for the population and possibly mass panic.
International events could potentially affect supplies of energy-producing products,
while local conditions could affect distribution of electricity, petroleum or natural gas.
The magnitude and frequency of energy shortages are associated with international
markets. Local and state events such as ice storms can disrupt transportation and
distribution systems. If disruptions are long lasting, public shelters may need to be
activated to provide shelter from either extreme cold or extreme heat. Stockpiles of
energy products eliminate short disruptions, but can also increase the level of risk to the
safety of people and property in proximity to the storage site.
The energy crisis of the 1970s had significant impacts on many consumers in
Iowa. High inflation and unemployment were associated with the excessive
dependence on foreign oil during the early and mid 1970s. An energy shortage of
that magnitude has not affected Iowa in recent years. Energy disruptions to the
8
City of McGregor have occurred, but have historically been of short duration and
are normally circumvented by activation of the city’s electrical power generating
plant, the McGregor Municipal Utility. In areas of the city that flood, both gas and
electric utilities are shut off by the utility companies during flooding.
Only when free market forces cease to provide for the health, welfare, and safety
of the citizens, can governments take appropriate actions to limit the effects of an
energy shortage. The state of Iowa has three strategies to limit the likelihood of
an energy shortage. Through voluntary and mandatory demand reduction
mechanisms; the substitution of alternative energy sources when possible; and
state government programs to curtail excessive use, energy supply and demand
can be kept in check. The federal government has a strategic petroleum reserve to
supplement the fuel supply during energy emergencies. Shortages, especially
electrical shortages, can be unpredictable with immediate effects. Natural events,
human destruction, price escalation, and national security energy emergencies
3
can cause unavoidable energy shortages. Recent severe winter storms that
caused extensive power outages in states like Kansas and Missouri in 2006 and
2007 add more credibility to the probability that some energy failure events will
impact the City of McGregor. A good example is the ice storm of February 24,
2007, which caused widespread extended power outages in Iowa and Clayton
County, though the City of McGregor was unaffected by that outage. It is also
worth noting that in order for the City of McGregor to be completely out of
electrical energy, both the power supply from Dairyland Power and the
capabilities of the McGregor Municipal Utility must be disrupted.
Because Iowa is almost entirely dependent on out-of-state resources for energy,
Iowans must purchase oil, coal, and natural gas from outside sources. World and
regional fuel disruptions are felt in Iowa. It is likely that increasing prices will
occur as market mechanisms are used to manage supply disruptions. This will
disproportionately affect the low-income population because of their lower
5
purchasing power. Agricultural, industrial, and transportation sectors are also
vulnerable to supply, consumption, and price fluctuations. In Iowa, petroleum
represents 97% of transportation fuel. Individual consumers such as commuters
are also vulnerable.
The effects of an energy shortage would be felt throughout the state. Because the
distribution systems are very developed, local shortages can quickly be covered.

A total natural gas or electrical energy disruption to the City of McGregor is
likely to affect all of the city.

November, 2008
Injuries and fatalities would not be directly caused by an energy shortage.
Injuries and fatalities could occur if energy was not available for heating during
extreme cold periods or for cooling during extreme heat. Hospitals, shelters,
emergency response vehicles and facilities, and other critical facilities would have
priority during energy shortages. Rotating blackouts, voluntary conservation
measures, and possibly mandatory restrictions could be used to limit the severity

of an energy shortage. Effects could range from minor heating and air
Impact
conditioning disruptions to transportation limitations all the way to civil unrest
due to the high demand, low supply, and subsequent high price. Business
disruption and increased cost of business would have far-reaching financial
implications across many sectors of the economy. The February 24, 2007 winter
storm and associated power outage which impacted nearly all of Clayton County
caused an estimated $10,000,000 in damages in the county.
The Iowa Department of Natural Resources Energy Bureau monitors domestic
and international energy situations and has developed a plan to deal with an
energy crisis. Signs that an energy shortage may be developing can be
recognized even months in advance, but energy shortages/emergencies can rise
suddenly and unexpectedly. Supply distribution problems in other countries and

local weather situations can lead to low supply coupled with high demand in a
matter of a day or two. A supply problem from Dairyland Power, the city’s
electrical provider would likely go unnoticed as the city’s electrical generating
plant; the McGregor Electrical Utility would be activated. The plant has the
capability of providing all of the city’s electrical power needs.

the United States for purposes of intimidation, coercion or ransom.
Liquid or solid contaminants can be dispersed using sprayers/aerosol generators or by
point or line sources such as munitions, covert deposits and moving sprayers.
Biological agents may pose viable threats from hours to years depending upon the
agent and the conditions in which it exits. Depending on the agent used and the
effectiveness with which it is deployed, contamination can be spread via wind and
water. Infections can be spread via human or animal vectors.
Iowa has not been immune to acts of terrorism or sabotage. The state has
experienced many bomb threats in the distant and recent past. The biological
terrorism history, fortunately, has been limited to threats and hoaxes only. While
1
these acts have caused terror, they have not resulted in injuries or deaths.
There have been no incidents of bioterrorism in the City of McGregor.
Internationally, such acts have, unfortunately, become quite commonplace, as
various religious, ethnic, and nationalistic groups have attempted to alter and
dictate political and social agendas, seek revenge for perceived past wrongdoing,
or intentionally disrupt the political, social, and economic infrastructure of
individual businesses, units of government, or nations. Unfortunately, there will
never be a way to totally eliminate all types of these clandestine activities.
3
Persons inclined to cause death and destruction are usually capable of finding a
way to carry out their plans. As perpetrators of terrorism improve their ability to
collect information, raise money and issue rhetoric, implementation of effective
counter measures becomes even more important. The most probable target for a
bioterrorism attack in the City of McGregor is the city’s water supply system.
Innocent people are often victims of terrorist activity targeted at certain
organizations and activities. Based on the method of delivery, the general public
is vulnerable to bio-terrorism. The American public is not vaccinated for many of
5
the agents used as weapons by terrorist groups. Iowa vaccinated volunteers
against smallpox at 15 Iowa hospitals in early 2003.
Because of the characteristics of the weapons terrorists use, the area can be
limited to a room, building, or the entire community. Depending on the agent
used and the effectiveness with which it is deployed, contamination can be
spread via wind and water. Infections can be spread via human or animal
5
vectors. Because of the variables described above, the geographic extent can
become quite broad before the incident is recognized as a terrorist act. A
bioterrorism attack on the City of McGregor’s water supply system holds the
potential for afflicting the entire population of the city.
The intent of the terrorist is to cause fear based on illness, injury, and death. A
bio-terrorism incident would likely result in illness at a minimum, with multiple
5
deaths and long-term health problems as a worst-case.

Use of conventional weapons and explosives against persons or property in violation of
the criminal laws of the United States for purposes of intimidation, coercion or ransom.
Conventional terrorism includes detonation of an explosive device on or near a target
delivered via person, vehicle, or projectile. Hazard effects are instantaneous; additional
secondary devices may be used, lengthening the duration of the hazard until the attack
site is determined to be clear. The extent of damage is determined by the type and
quantity of explosive. Effects are generally static other than cascading consequences,
incremental structural failures, etc. Conventional terrorism can also include tactical
assault or sniping from remote locations.
Iowa has not been immune to acts of terrorism or sabotage. The state has
experienced many bomb threats in the distant and recent past. During the spring
of 2002, 18 pipe bombs were found in mailboxes in five states stretching from
Illinois to Texas, including Iowa. Six people were injured in the bombings in
Iowa and Illinois.
In Clayton County the only incidents of conventional terrorism that have
occurred have involved the schools. According to Central Community School
District officials, the school system was the subject of one bomb threat in 1999. A
search of the school found no bomb. There have also been bomb threats at the
Clayton Ridge Community School District High School in Guttenberg. There have
been no such incidents at the MFL MarMaq Middle School in McGregor or any
other location in the city.
Unfortunately, there will never be a way to totally eliminate all types of these
clandestine activities. Persons inclined to cause death and destruction are usually
capable of finding a way to carry out their plans. As perpetrators of terrorism
improve their ability to collect information, raise money and issue rhetoric,
implementation of effective counter measures becomes even more important.
One of the most likely targets of a conventional terrorism attack in the City of
McGregor is the MFL MarMaq Middle School.
Energy decreases logarithmically as a function of distance from seat of blast.
Terrain, forestation, structures, etc. can provide shielding by absorbing or
deflecting energy and debris. Exacerbating conditions include ease of access to
target; lack of barriers/shielding; poor construction; and ease of concealment of
device.
Extent of damage is determined by type and quantity of explosive. Effects are
generally static other than cascading consequences, incremental structural failure,
etc.
Property damage and injuries are almost certain outcomes if a conventional bomb is
detonated in a developed or populated area. Threats and scares have psychological
impacts and disrupt activities at a cost to productivity.
Explosions are usually instantaneous; additional secondary devices may be used,
lengthening the duration of the hazard until the attack site is determined to be clear. Acts
of terrorism can be immediate and often come after little or no warning. There are
occasions when terrorists have warned the targeted organization beforehand, but often the
attack comes without previous threat. Terrorists threaten people and facilities through
"bomb threats" and other scare tactics. Even if it is a shallow threat, precautions must be
taken to ensure the safety of the people and property involved.

Structural Fire

Vulnerability
An uncontrolled fire in populated area that threatens life and property and is beyond
normal day-to-day response capabilities.
Structural fires present a far greater threat to life and property and the potential for
much larger economic losses. Modern fire codes and fire suppression requirements in
new construction and building renovations, coupled with improved fire fighting
equipment, training, and techniques, lessen the chance and impact of a major urban fire.
Most structural fires occur in residential structures, but the occurrence of a fire in a
commercial or industrial facility could affect more people and pose a greater threat to
those near the fire or fighting the fire because of the volume or type of the material
involved.
Structural fires are almost a daily occurrence in some communities. Nearly all are
quickly extinguished by on-site personnel or local fire departments. There have
been 1,535 deaths in Iowa from fires from 1974 to 2002 (not including the years
1978 to 1979).
The McGregor Hook and Ladder Company No. 1 Fire Department responds to an
average of 30 alarms per year. Fire Department reports indicate the department
responds to an average of 1 structural fire in the City of McGregor annually.
There are no recorded fire deaths or injuries in structural fires for the City of
McGregor.
Given the history of structural fire incidents in the City of McGregor, it is a
certainty that the city will experience at least one structural fire annually.
Even with the department’s focus on fire prevention effort, both residential and
nonresidential structural fires, fires will continue to occur. During colder months,
clogged chimneys and faulty furnaces and fire places can increase the probability
of structural fires. Structural fires occur routinely in the City of McGregor.
Particularly vulnerable in the City of McGregor are older structures with
outdated electrical systems not built to current fire codes. Combustible building
materials obviously are more vulnerable than structures constructed of steel or
concrete. Structures without early detection devices are more likely to be
completely destroyed before containment by response agencies. Structures in
areas served by older, smaller, or otherwise inadequate water distribution
infrastructure such as water mains and hydrants are also at significant risk.
Problems vary from region to region, often as a result of climate, poverty,
education, and demographics, but Iowa has about 13.4 fire deaths per million
population. The fire death risk for the elderly is more than two times that of the
average population. The fire death risk is nearly two times that of the average
population for children 5 years of age or less.

With modern training, equipment, fire detection devices, and building
regulations and inspections, most fires can be quickly contained and limited to
the immediate structure involved. Certain circumstances, such as the
involvement of highly combustible materials or high winds, can threaten a larger
area. The age and density of a particular neighborhood can also make it more
vulnerable to fire due to the spreading of fire from neighboring structures.
Based on national averages in the 1990s, there is one death for every 119
residential structure fires and one injury for every 22 residential fires. On
average, each residential fire causes nearly $11,000 of damage. In nonresidential
fires, there is one death for every 917 fires, one injury for each 52 fires, and each
nonresidential fire causes an average of nearly $20,000 in damage.
While fires usually start with little or no warning time, alert devices can allow
time for responders to contain the fire and allow occupants to evacuate the area.
McGregor Hook and Ladder Company No. 1 volunteer firefighter are notified of
fire incidents within the City of McGregor by pager via the Clayton County
Sheriff’s Office dispatch.

COMPOSITE SCORING WORKSHEET FOR HAZARDS IDENTIFIED BY CITY OF
MCGREGO HAZARD MITIGATION PLANNING COMMITTEE
Each hazard identified by the City of McGregor Hazard Mitigation Planning Committee can also
either be triggered by some other hazard or cause another hazard to occur. Thus they become
part of an event cascade. In developing a composite score for ranking the hazards identified by
the City of McGregor Hazard Mitigation Planning Committee a composite score was developed
that included the Hazard Analysis score and Cascading event scores consisting of the number of
hazards a hazard can resulting from and the number of hazards a hazard can trigger. The
cascading event scores were determined from a matrix found in Appendix 5A of the Iowa
Hazard Analysis.

VULNERABILITY ASSESSMENT
This section is intended to further identify the populations and areas that are most vulnerable
during each of the identified hazards for the City of McGregor. Whenever possible these
vulnerability assessments are supported by hard data obtained from a variety of sources.
A transportation hazardous materials incident can occur anywhere vehicles travel, so any area is
considered vulnerable to an accident. People, pets, livestock, and vegetation in close proximity
to transportation corridors and populations downstream, downwind, and downhill of a released
substance are particularly vulnerable. Depending on the characteristics of the substance released,
a larger area may be in danger from explosion, absorption, injection, ingestion, or inhalation.
The City of McGregor is most vulnerable to experiencing a transportation hazardous materials
incident on the major highways that serve the community. This includes state highways 18 and
76. Another potential source is due to an incident involving barge or other traffic on the
Mississippi River. Another area of vulnerability is due to the Canadian Pacific Railroad which
passes up to seven trains a day carrying large quantities of hazardous materials through the City
of McGregor. In 2008 the Canadian Pacific Railroad had two significant incidents in Clayton
County, one which resulted in a spill of 12,000 gallons of diesel fuel. Property adjacent to these
transportation routes is vulnerable to damage from a hazardous materials release and people
living or traveling near an incident are vulnerable to physical harm from any release that may
occur. Depending on the characteristics of the substance released, a larger area than the
immediate surroundings may be in danger from explosion, absorption, injection, ingestion, or
inhalation.
An agreement between the Clayton County Emergency Management Agency and the Linn
County Hazardous Materials Response Team, headquartered in Cedar Rapids, enhances local
emergency response agencies capability of managing a hazardous materials incident.
Structural Fire
Older structures with outdated electrical systems not built to current fire codes are particularly
vulnerable to fire. Combustible building materials obviously are more vulnerable than structures
constructed of steel or concrete. Structures without early fire detection devices are more likely to
be completely destroyed before a fire is contained by a response agency. Structures in areas
served by older, smaller or otherwise inadequate water distribution infrastructure (i.e., water
mains and hydrants) are also at significant risk. Problems vary from region to region, often as a
result of climate, poverty, education, and demographics.
Iowa has approximately 13.4 fire deaths per million people annually. According to the United
States Fire Administration, based on national statistics, senior citizens ages 65 and over, and
children under the age of 5 have the greatest risk of fire death. The fire death risk among seniors
over 65 is more than double; over age 75 triple; over age 85, three and one half times that
experienced by the general population. Children under the age of 10 account for an estimated
22.2 percent of all fire deaths.
90
November, 2008
Though the City of McGregor has experienced no fire deaths in its recent history, the city has
248 residents (20 percent of its population) who are in the ―most at risk‖ categories for fire death.
Key elements of effective fire suppression for the McGregor Hook and Ladder Co. No. 1 Fire
Department includes staffing, firefighter training, and modern firefighting equipment, all of
which present challenges to most contemporary fire departments.
Flash Flood
Due to the City of McGregor’s proximity to the Mississippi River and the confluence of valleys
that pour runoff water into the city, flooding occurs frequently in the city. Of the numerous
floods that have impacted the City of McGregor, the National Climatic Data Control Center
documents the floods of 5/16/1999, 5/21/2004, 5/23/2004 and 7/17/2007 as flash floods. The
7/17/2007 flash flood caused $1.3 million in damages to the city. Though flood mitigation
measures such as construction of a levee erection of concrete berms have been undertaken, they
have proven inadequate to protect the city from floods. The City of McGregor has documented
103 structures that are located within flood zones A and B. These structures include 54 classified
as residential and 49 others including commercial, storage and public or municipal facilities.
Among the public facilities in the flood plain are: McGregor Municipal Utilities; McGregor
Sewage Treatment Plant; Well No. 6; McGregor City Hall; McGregor Fire Station; McGregor
Public Library; McGregor Museum and the Riverfront Park Shelter House. Total value of all
these structures from records provided by the City of McGregor in September, 2008 is assessed
at $11,862,723.
River Flood
Due to the City of McGregor’s proximity to the Mississippi River and the confluence of valleys
that pour runoff water into the city, flooding occurs frequently in the city. Of the numerous
floods that have impacted the City of McGregor, the National Climatic Data Control Center
documents three river flood events that have impacted the city since 1993. Though flood
mitigation measures such as construction of a levee erection of concrete berms have been
undertaken, they have proven inadequate to protect the city from floods. The City of McGregor
has documented 103 structures that are located within flood zones A and B. These structures
include 54 classified as residential and 49 others including commercial, storage and public or
municipal facilities. Among the public facilities in the flood plain are: McGregor Municipal
Utilities; McGregor Sewage Treatment Plant; Well No. 6; McGregor City Hall; McGregor Fire
Station; McGregor Public Library; McGregor Museum and the Riverfront Park Shelter House.
Total value of all these structures from records provided by the City of McGregor in September,
2008 is assessed at $11,862,723.
Tornado
Everyone is vulnerable to the powerful forces that accompany a tornado. There are those who are
more vulnerable than others. For example:
1. People in automobiles
2. People in mobile homes
91
November, 2008
3. People who may not understand warnings due to language barriers
4. The elderly and very young
5. People with physical or mental impairments.
In the event of a tornado the City of McGregor has an outdoor warning siren that given enough
time, allows people to search for suitable shelter when the siren is activated.
As identified in the community profile section of the plan, certain populations are considered
more vulnerable than others based on their ability to properly respond, even after proper
notification has been given. For purposes of this plan these population shall include seniors age
65 and over, children age 18 and under, and those individuals with mental and/or physical
handicaps. Based on census figures we are able to determine that 352 individuals in the
community are identified as vulnerable based solely on age. This accounts for approximately 40
percent of the population. No solid data could be acquired as to the number of physically and/or
mentally challenged populations.
Another population considered to be more at risk than others are those in mobile homes.
According to 2000 Census data the City of McGregor had 16 mobile home units within the city
limits. This comprises 3.1 percent of the housing units in the city. Using the average household
size (2.34 people/housing unit) as a calculation tool, we can assume that the number of people
residing in mobile home in the City of McGregor is approximately 38.
Anyone who relies on communications technology such as telephones, cell phones, computers or
radios is vulnerable to experiencing some type of communications failure. Most communication
systems that are highly necessary have backup and redundant designs to provide continuity of
service. Financial or business institutions that rely on cyber technology for the transfer of data
and business transactions can suffer significant disruption of business activities due to
communications failures. Emergency responders and peace officers can be impacted by
disruptions to radio communications capabilities that impaired communications and paging
capabilities. Terrain and the location of the City of McGregor has historically presented radio
communications problems.
Because of the large number of streets, highways and intersections located in the City of
McGregor, any intersection could be the site of a traffic accident. The hazards of highway
accidents are further compounded by the rolling, hilly terrain of the area which makes driving
even more hazardous under poor driving conditions. Persons driving on major thoroughfares
such as Highways 76 and 18 are more vulnerable to traffic accidents due to the larger number of
drivers on these roads and the higher corresponding speed limits.
92
November, 2008
Windstorm
Everyone is vulnerable to the powerful forces that accompany a windstorm. There are those who
are more vulnerable than others. For example:
1. People in automobiles,
2. People in mobile homes,
3. People who may not understand warnings due to language barriers,
4. The elderly and very young, and
5. People with physical or mental impairments.
In the event of a windstorm the City of McGregor has an outdoor warning siren that given
enough time, allows people to search for suitable shelter when the siren is activated.
As identified in the community profile section of the plan, certain populations are considered
more vulnerable than others based on their ability to properly respond, even after proper
notification has been given. For purposes of this plan these population shall include seniors age
65 and over, children age 18 and under, and those individuals with mental and/or physical
handicaps. Based on census figures we are able to determine that 352 individuals in the
community are identified as vulnerable based solely on age. This accounts for approximately 40
percent of the population. No solid data could be acquired as to the number of physically and/or
mentally challenged populations.
Another population considered to be more at risk than others are those in mobile homes.
According to 2000 Census data the City of McGregor had 16 mobile home units within the city
limits. This comprises 3.1 percent of the housing units in the city. Using the average household
size (2.34 people/housing unit) as a calculation tool, we can assume that the number of people
residing in mobile home in the City of McGregor is approximately 38.
Energy Failure
An energy failure could occur by many means, for example, as a result of storms or severe
weather, a man-made accident, terrorist incident or equipment failure. Whatever the origin of the
disruption, particularly those of prolonged duration, an energy disruption holds the potential of
adversely affecting every person, household, institution or business within its sphere of
influence. In its most extreme state an energy disruption will create a high degree of personal
hardship and affect the health and well being of a high percentage of those affected. The majority
of residents in any community, such as the City of McGregor, have done little to prepare
themselves for a prolonged energy disruption situation. Their risk is minimized, however, due to
the City of McGregor having its own electrical generating plant, the McGregor Electrical Utility,
that could provide electrical power in a situation where Dairyland Power, the city’s primary
electrical provider, suffers an energy failure to the city.
93
November, 2008
Everyone is vulnerable to the powerful forces that accompany thunderstorms and lightning. The
most vulnerable are people who are out in the open during these events or who live in or work in
structures without lightning protection. Other vulnerabilities associated with thunderstorms and
lightning are those that occur due to the cascading affect of these events. Thunderstorms are
sometimes accompanied by heavy rain which lead to floods and lightning sometimes strikes
buildings and starts fires or is associated with localized or widespread power outages when it
strikes energy infrastructure or with communications failures when it strikes radio and phone
communications infrastructure. And, lightning does cause fires also.
Severe Winter Storm
Residents of the City of McGregor who are most vulnerable to the effects of a winter storm are
those who cannot fend for themselves in times of severe weather. Example populations would be
the elderly or disabled who rely on outside entities for delivery of food or medicine for their
livelihood. In the City of McGregor there are 219 residents (25 %of the population) over the age
of 65 according to 2000 census information People who work outdoors are also at greater risk of
being affected by wind chill, extreme low temperature, and wet winter conditions.
Unfortunately, based on the large area that these storms can cover and the cascading effects that
can accompany them, the entire population of the City of McGregor is vulnerable to some type
of impact from a winter storm..
Levee Failure
The City of McGregor is protected from flood waters of the Mississippi River by a 1,500 feet
long dirt levee built by the US Army Corps of Engineers in 1969 across the face of the town,
paralleling Front Street. The levee is part of the Rock Island District levee system. Since the
levee was constructed local officials have noticed a settling of the levee by as much as one to one
and a half feet. No information from any formal study could be found to substantiate this claim.
The concern of local officials is that if the levee is breached by a 100 or 500 year recurrent flood,
all 103 structures with a total assessed property value of $11,862,723 would be affected. This
also endangers 126 residents of the City of McGregor. With 31 Rock Island system levees over
topped in the Midwest floods of 1993 and 13 overtopped or breached in the Midwest floods of
2008 the concerns of local officials can be judged as legitimate.
Fixed Facility Hazardous Material Incident
A hazardous materials accident can occur almost anywhere, so any area is considered vulnerable
to an accident. People, pets, livestock, and vegetation in close proximity to facilities producing,
storing, or transporting hazardous substances are at higher risk. Populations downstream,
downwind, and downhill of a released substance are particularly vulnerable.
The most vulnerable people in the City of McGregor to injury or health affects from a fixed
facility hazardous materials incident are workers associated with hazardous materials at the
facilities and emergency responders and people living in close proximity to fixed facilities
94
November, 2008
having hazardous materials. Because of the wide vary of variables associated with a hazardous
materials release, vulnerability estimates are difficult to determine. Some releases may have
virtually no affect, while significant portions of the county could be affected in the case of an
anhydrous ammonia or LP gas leak.
Depending on the characteristics of the substance released, a larger area may be in danger from
explosion, absorption, injection, ingestion, or inhalation. Occupants of areas previously
contaminated by a persistent material may also be harmed either directly or through consumption
of contaminated foods and water.
The City of McGregor has Agri-Bunge and the McGregor Municipal Utility Plant that are EPA
regulated due to the hazardous materials used in processes associated with the business or facility
or that is stored at the facility. Given the presence of these facilities and a history that includes
one incident of a fixed facility hazardous materials release in the City of McGregor, it is highly
probable there will be future fixed facility hazardous materials incidents in the City of
McGregor.
Facilities are required to have plans that address hazmat release situations and emergency
procedures for the populations residing in the areas surrounding those facilities. Responding
personnel are required to be trained to hazmat operations level to respond to the scene and those
personnel that come into direct contact with the released substance are required to have hazmat
technician level training. All McGregor emergency responders have completed this requirement.
An agreement between the Clayton County Emergency Management Agency and the Linn
County Hazardous Materials Response Team, headquartered in Cedar Rapids, improves the
capability of local responders to manage a hazardous materials incident.
Extreme Heat
Everyone in the city of McGregor is susceptible to the impacts of a heat wave or extreme heat
event. Those who have an elevated risk include the elderly, young children, chronic invalids,
those on certain medications or drugs, persons who are over their recommended weight,
alcoholics, and individuals who work outdoors or in confined spaces without air conditioning.
Furthermore, economic class can also figure into who is vulnerable. Those individuals or
families who cannot afford air conditioning or do not have access to air conditioning are also
more susceptible to the effects of elevated temperatures.
The level of vulnerability can be greatly reduced by taking certain precautionary steps. Such
measures include, but are not limited to, drinking plenty of water to stay hydrated, moving to air
conditioned areas, using sun block, reducing the amount of physical exertion normally expended,
etc.
95
November, 2008
Dam Failure
The City of McGregor could be affected by failure of the Pikes Peak or Siegele Flood Control
Dams. Though there has been no instance of so much as an overflow of these dams since they
were built in 1938, both of these dams are considered high risk according to the National
Performance of Dams Program. Representatives of the Iowa DNR who inspect the dams consider
them ―hydrologically inadequate.‖ Property and infrastructure that could be affected by failure of
either of these dams lie within the floodplain area of the city. This includes 54 residential and 49
others including commercial, storage and public or municipal facilities. Among the public
facilities in the flood plain are: McGregor Municipal Utilities; McGregor Sewage Treatment
Plant; Well No. 6; McGregor City Hall; McGregor Fire Station; McGregor Public Library;
McGregor Museum and the Riverfront Park Shelter House. Total value of all these structures
from records provided by the City of McGregor in September, 2008 is estimated at $11,862,723.
Appendix 8, page 206 provides a map detailing the Dam Overflow Basins of the Pikes Peak and
Siegele Flood Control Dams.
The most glaring vulnerability to a terrorist act appears to be an act of conventional terrorism by
a renegade terrorist or organized group of terrorists targeting an area of mass assembly such as
the MFL MarMac Middle School in McGregor. The school has 350 students and staff. The
school has never incurred such an act of terrorism. The school has taken many steps to increase
security, but has surveillance and security needs.
Bio-terrorism
A major human welfare concern, given the many possible acts that can be perpetrated is
bioterrorism. The introduction of a human disease such as anthrax by a terrorist into a local
environment such as somewhere in the City of McGregor could have a range of consequences
from a small localized infection of a single individual to a sweeping pandemic affecting a large
portion of the city’s population. The City of McGregor has no plans in place to taken no
measures to address a biological terrorism event. The Clayton County Emergency Management
Agency and Clayton County Department of Public Health has developed broad-based plans for
such a situation, but nothing specific to the City of McGregor.
Another serious threat to the City of McGregor involving an act of bio-terrorism is
contamination of the city’s water supply. Water for the city is supplied by two active wells at 105
Eagle Drive and 118 Main Street. Some well field protection measures have been taken. The
city has an above ground covered bluff-top water reservoir which holds a maximum of 297,000
gallons of water. The city has a chlorination water treatment plant located at 118 Main Street.
The City of McGregor’s Water Operator manages and maintains the city’s water supply system.
Both of these facilities have minimal security.
An act of bio-terrorism involving the city’s water supply has the potential for affecting every
resident of the city.

Landslide
The City of McGregor is located in a valley surrounded by moderate to steeply sloping hillsides.
This terrain feature has historically created small localized landslide problems that have caused
minimal damage. The potential exists for a larger and more devastating landslide that could
damage structures and infrastructure in the City of McGregor. There are 40 residential and 25
commercial properties with an assessed value of $2.2 million in the City of McGregor that are
located in areas at the base of hills or on hillsides that could be affected by a landslide.

HAZARD PRIORITIZATION
Once the City of McGregor Hazard Mitigation Planning Committee had identified and scored the
hazards, they examined each hazard in relation to the risk that hazard presented to the
community. All of the identified hazards were then given a priority state. The Committee defined
high-risk hazards to be those hazards that caused substantial damage to the community in the
past, have a high probability of occurring in the future, and have the potential to affect a large
proportion of the community. High-risk hazards were also considered to be the hazards for which
immediate planning and mitigation activities are to be focused.
The Committee considered medium-risk hazards to be those hazards that should be addressed by
the community in the future; however, the need for mitigation activities for these hazards was not
considered to be as immediate. Finally, the Committee defined low risk hazards as hazards that,
at present time, have an acceptable level of risk. The hazards are listed below by priority.

HAZARD MITIGATION PLAN GOALS
The City of McGregor Hazard Mitigation Planning Committee set as a priority the development
of broad-based goals that would address a multitude of hazards and encompass a variety of
mitigation activities. By identifying these goals the Committee was able to develop mitigation
action steps that would work toward the broader goal. The hazard mitigation planning goals
developed by the Committee are identified are as follows:
1.
2.
3.
4.
5.
6.
7.
Improve the quality of life by mitigating potential hazards.
Take steps to mitigate the probable negative consequences that may occur as a
result of natural and human caused/combination disasters.
Identify potential funding sources needed to accomplish identified mitigation
projects.
Protect the health and welfare of the entire community by enhancing the training
and capabilities of all first responder organizations.
Return to pre-disaster or improved conditions as soon as possible after a disaster
occurs.
Protect businesses and industries by reducing the impact of hazards in order to
ensure economic viability of the city.
Continued compliance with NFIP requirements.
Each of the mitigation activities identified as a ―Future Hazard Mitigation Activity‖ in the
following section can be related to at least one of the hazard mitigation plan goals.
99

FUTURE HAZARD MITIGATION ACTIVITIES
While the mitigation activities discussed previously in this plan detail the City of McGregor’s
efforts to mitigate hazards when possible, and to respond to hazards in a timely and efficient
manner, the City also recognizes that there are many more mitigation activities and projects that
would benefit the residents of the community. The Hazard Mitigation Planning Committee
recognized this fact and developed a list of future hazard mitigation activities that, if
accomplished, would serve to further reduce the risk of hazards to the community. The list
includes a combination of projects the McGregor Hazard Mitigation Planning Committee feels
the community should try to accomplish. In addition, this list includes mitigation efforts that are
ongoing that the Committee view as vital to the continued well-being of the public. The final list
of future hazard mitigation activities was developed by the committee by first reviewing a list of
252 potential mitigation measures that any community could consider. After discussion and
review and incorporation of other mitigation measure concerns expressed by committee
members, this list was narrowed to the final list of future hazard mitigation projects accepted by
the Hazard Mitigation Planning Committee for inclusion in this plan and adoption by the
McGregor City Council. The entire list of 252 potential mitigation measures presented to the
hazard mitigation planning committee for consideration is found in Appendix 5, page 185.
Future hazard mitigation activities determined by the McGregor Hazard Mitigation planning
committee are as follows. Hazards are presented in the order from the ranking determined by the
composite scoring worksheet.

ANALYSIS OF MITIGATION ACTIVITIES—STAPLEE CRITERIA
The City of McGregor Hazard Mitigation Planning Committee used the STAPLEE evaluation
criteria (Social, Technical, Administrative, Political, Legal, Economic and Environmental) in
narrowing the list of potential mitigation measures to the 93 future hazard mitigation activities
accepted by the committee and adopted by the McGregor City Council. The Committee
identified a time line for each activity, identified the responsible party or parties for each activity
and finally related each activity to at least one of the five Hazard Mitigation Plan Goals.
Below is a summary of the STAPLEE evaluation criteria applied to each mitigation activity:
Social
Evaluates public support of the overall implementation strategy and specific mitigation actions.
Factors the Committee considered were:

Will the action adversely affect one segment of the population?

Will the action disrupt established neighborhoods or cause the relocation of lower
income people?

Is the action compatible with present and future community values?
Technical
Evaluates the technical feasibility of the proposed action. Factors the Committee considered
were:

How effective is the action in avoiding or reducing future losses?

Will it create more problems than it solves?

Does it solve the problem?
Administrative
Evaluates the community's staffing, funding, and maintenance capabilities. Factors the
Committee considered were:

Does the community have the staff, technical experts, and/or funding to
implement the action?

Can the community provide the necessary maintenance?

Can it be accomplished in a timely manner?
Political.
Evaluates the political acceptability of the action. Factors the Committee considered were:

Is there political support to implement and maintain the action?

Have political leaders participated in the planning process?

Have all stakeholders been provided with an opportunity to participate in the
planning process?
105
November, 2008
Legal
Evaluates the community's legal authority to implement the action. Factors the Committee
considered were:


Does the city have authority to implement the action?
Are the proper laws, ordinances and resolution in place to implement the action?
NOTE: The City has the legal authority to implement all alternatives selected for consideration.
Economic
Evaluates economic feasibility and cost-effectiveness of the action. Factors the Committee
considered were:

Are there current sources of funds 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 the
action?

Does the action contribute to other community economic goals?

What proposed actions should be considered but be "tabled" for implementation
until outside sources of funding are available?
Environmental
Evaluates the impact on the environment. Factors the Committee considered were:


How will the action affect the environment (land, water, endangered species)?
Will the action comply with local, state, and federal environmental laws or
regulations?
Each activity was also given a priority ranking of 1, 2 or 3: Following is the criteria applied to
ranking the mitigation activities.
1: Those mitigation activities that are ongoing in the community and need to be sustained. Those
activities that would have the largest and most immediate mitigation impact on threats to
the lives of McGregor residents and property in the City of McGregor. Mitigation
activities that the City of McGregor can undertake with the resources the city has
available. Mitigation activities that are required in order to satisfy regulation or
compliancy issues.
2: Those mitigation activities that are beyond the resources of the city of McGregor and are only
achievable with an infusion of resources such as a grant.
3: Those mitigation activities that are of the lowest impact. Mitigation activities that address
hazards that are of the remotest nature in their possibility of occurrence.

Establish ordinance to require fire extinguishers in multi-family units
Having a functional fire extinguisher readily available is an important
fire safety measure that allows a citizen to extinguish a fire while it is in
its incipient phase before it grows. Currently the City of McGregor has
no legal recourse requiring citizens to have a functional fire extinguisher
in their residencies. By requiring extinguishers in residencies the threat
of devastating fires will be significantly reduced.

An economical and efficient way of detecting a fire while it is still in its
incipient phase and providing a notice to building residents so that they can
exit and save their lives is use of working smoke detectors. Since their
invention, residential smoke detectors have saved millions of dollars in
property damage by fire and saved thousands of lives.
There is no ordinance in the City of McGregor that requires smoke detectors in
residencies except the state ordinance requiring smoke detector use in multifamily apartments. Estimates are that as high as one half the residencies in any
given community either lack smoke detectors or have smoke detectors that do
not function.
There are many measures that can be taken to encourage installation and
maintenance of smoke detectors by citizens. One method is a door-to-door
campaign by the Fire Department. Another is distribution of printed materials
such as those produced by the US Fire Administration that describe smoke
detector operation, maintenance and placement to City of McGregor residents.
The cost of this project can vary substantially based on what type of
educational effort is made. For purposes of this plan, the cost estimate will
assume that the City will contact every household by mail. According to the
2000 Census there are 518 households in the city. Assuming $1.00 cost per
household (copies, postage and handling) it would cost the City approximately
$518 annually for the educational effort.

Encourage purchase of NOAA weather radios by vulnerable populations
The purpose of NOAA weather radios is to increase the likelihood that the
general public is given sufficient warning of any impending hazard.
Unlike outdoor warning sirens, NOAA weather radios are intended to warn
people who are indoors and are loud enough to wake an individual even if they
are sleeping. Furthermore, the radios can follow a warning alert with
information on what the specific threat is and how one should react.
The Clayton County EMA has purchased NOAA weather radios and placed
them in areas of large population (i.e. nursing homes, schools, library, city hall
etc.).
The next step is to encourage citizens to install NOAA weather radios in
their home through such means as print media.
This is an ongoing mitigation effort.
Costs of the radios could be as high as $90 apiece.

In order to prevent future damage and financial loss due to river or flash
flooding, the City of McGregor needs to discourage, by ordinance if
necessary, construction of dwellings or other structures and basic
infrastructure in areas of the city that are prone to flooding. Currently 103
structures that are vulnerable to flood damage are located within the 100
year flood plain of the city. In order to avert escalation of the number of
structures that could be damaged by floods the city needs to restrict or if
possible prohibit further development in the 100 year flood plain. This can
be accomplished through adding more restrictive language to the city’s
Flood Plain Regulations found in Chapter 160 of the City of McGregor
Code of Regulations.

Update flood maps
FEMA is currently working on updating flood risk identification using
state of the art technology and through partnerships with communities,
through the Map Modernization Initiative. The products of this effort are
called Digital Flood Insurance Rate Maps (DFIRMs). As is the case with
all Flood Insurance Rate Maps, these new DFIRMS are used to calculate
the cost of insurance premiums, to establish flood risk zones and base
flood elevations to mitigate against potential future flood damages to
properties. Insurable buildings located in high-risk areas, called Special
Flood Hazard Areas (SFHAs), secured by a Federally backed loans, are
required to purchase flood insurance.
The floods of 2008 and previous floods which impacted the City of
McGregor, have demonstrated a need for the updated maps as properties
that are shown as being out of the 100 year floodplain according to current
maps have indeed incurred damage. The current FEMA flood map, dated
10/17/1975, as can be seen in Appendix 6, page 192, is inadequate and

Action Step 5
Analysis
Effective management of flooding and excess water situations for the City of
McGregor involves management of storm water influencing the City. The City of
McGregor is influenced by runoff water from a large network of hills and valleys
surrounding the city that are beyond the corporate limits of the city. In order to
effectively manage the storm water influencing the City of McGregor, these
surrounding rural areas must be managed as well. In order to accomplish this, a
united effort must be achieved that includes private, commercial and
governmental property owners surrounding the City of McGregor as well as City
of McGregor representatives and other interests such as the Iowa DNR. The
means of accomplishing this is by establishing a storm watershed district with
representation of all interests as detailed above in order to establish common
goals and objectives for effective storm watershed management and to provide
incentives for undertaking storm water management measures.

In order to prevent future damage and financial loss due to river or flash
flooding, the City of McGregor needs to discourage, by ordinance if
necessary, construction of dwellings or other structures and basic
infrastructure in areas of the city that are prone to flooding. Currently 103
structures that are vulnerable to flood damage are located within the 100
year flood plain of the city. In order to avert escalation of the number of
structures that could be damaged by floods the city needs to restrict or if
possible prohibit further development in the 100 year flood plain. This can
be accomplished through adding more restrictive language to the city’s
Flood Plain Regulations found in Chapter 160 of the City of McGregor
Code of Regulations.

Update flood maps
FEMA is currently working on updating flood risk identification using
state of the art technology and through partnerships with communities,
through the Map Modernization Initiative. The products of this effort are
called Digital Flood Insurance Rate Maps (DFIRMs). As is the case with
all Flood Insurance Rate Maps, these new DFIRMS are used to calculate
the cost of insurance premiums, to establish flood risk zones and base
flood elevations to mitigate against potential future flood damages to
properties. Insurable buildings located in high-risk areas, called Special
Flood Hazard Areas (SFHAs), secured by a Federally backed loans, are
required to purchase flood insurance.
The floods of 2008 and previous floods which impacted the City of
McGregor, have demonstrated a need for the updated maps as properties
that are shown as being out of the 100 year floodplain according to current
maps have indeed incurred damage.
As per FEMA schedule for completing Map Modernization efforts and

Analysis
Effective management of flooding and excess water situations for the City of
McGregor involves management of storm water influencing the City. The City of
McGregor is influenced by runoff water from a large network of hills and valleys
surrounding the city that are beyond the corporate limits of the city. In order to
effectively manage the storm water influencing the City of McGregor, these
surrounding rural areas must be managed as well. In order to accomplish this, a
united effort must be achieved that includes private, commercial and
governmental property owners surrounding the City of McGregor as well as City
of McGregor representatives and other interests such as the Iowa DNR. The
means of accomplishing this is by establishing a storm watershed district with
representation of all interests as detailed above in order to establish common
goals and objectives for effective storm watershed management and to provide
incentives for undertaking storm water management measures.

The City of McGregor views the education of the public as an essential step in
mitigating any hazard. While a comprehensive list of every possible topic of
education is not listed, a few items deemed of substantial importance for the
mitigation of a tornado or high wind event are as follows:
 What does the siren indicate?
 Where to find timely information regarding severe weather?
 Where is the safest place to take cover?
 What options are available to me (shelters, under bed cages,
basements, ete.)?
 What is the difference between a tornado watch and a tornado
warning?
This step can be implemented in a number of ways, but specific issues that will

mufti-lingual formats in order to ensure that most, if not all, individuals in the
community are able to understand the information.
Furthermore, for successful implementation of this action step, the City is

The current spillways of the Pikes Peak and Siegele dams are compacted
soil, making each dam susceptible to soil erosion. Erosion of the spillways
would be enhanced during a dam overflow, thereby making the dam more
susceptible to weakening and failure. To prevent erosion form occurring,
the US Army Corps of Engineers has suggested placing a concrete
spillway on the sides of each dam to take away rising water should water
overflow one or both of the dams. Construction of concrete spillways will
enhance resistance of the spillways to erosion and reduce the potential for
dam failure. The dams currently have overflow structures approximately
4/5 of the way up the down face. Should these structures not be adequate
to handle water within the storage basins, the concrete overflows will
allow water to leave without damaging the dam structure.

As with the other educational action steps identified in this plan, the act of
educating the public is viewed as essential, cost effective, and an obligation by
the County and the service organizations that serve the City’s residents. Some
examples of the types of educational topics needed include how the public can
prepare itself for an event. This would include informing people how to prepare
their own personal Emergency Disaster Plan, how to find information regarding
an event, how to recognize and where to report suspicious activities, how to
shelter in place, knowing what items to keep on hand, etc.
The purpose of this action step is to help the public prepare themselves and to
respond should a terrorist event occur in or near their community. By
maintaining an informed public, the County believes that the severity and cost of
a terrorist attack can be significantly reduced. Furthermore, much of the
education and preparation encouraged to mitigate terrorism also has benefits that
will help people prepare and respond to other hazards.
This action step is not exclusive to the City of McGregor. Rather, the education
of the public on this subject is a cooperative effort between the city and several
local, State and Federal organizations, both public and private.

PLAN MAINTENANCE, REVIEW, AMENDMENT, OTHER PLANS
Mitigation Prioritization
As shown in previous sections of the plan, there are a number of hazards that could potentially
affect the residents of the City of McGregor. In relation, as identified in this plan, there are also a
large number of activities that could be undertaken to mitigate the effects of these hazards.
Unfortunately, the City of McGregor does not have an unlimited amount of funds, funding
sources or human resources for mitigation projects. With this in mind, the City of McGregor
Hazard Mitigation Planning Committee prioritized the mitigation activities for each hazard, as
detailed in the above section of this plan.
In order to refine mitigation needs and priorities even further, the planning committee identified
and generalized the ten most attractive mitigation steps. These top mitigation steps were
determined by balancing the need for the project(s), the amount of good that it will accomplish,
the feasibility of the project, and the availability of outside (State and Federal) funding
assistance. The top mitigation objectives as identified by the planning committee are as follows:
1. Educate the Public on matters pertaining to hazard mitigation as discussed in this plan
(Continuing).
2. Seek out funding opportunities to help implement projects identified in this plan (Short
Term).
3. Continue all current mitigation efforts as identified in this plan (Continuing).
4. Make necessary updates and improvements to communications systems and capabilities
(Short Term).
5. Protect all public infrastructure from future hazard events (i.e. winter storms, security
concerns, etc.) (Long Term).
6. Improvement in security for critical facilities (Short Term).
7. Pursue training opportunities for first responders who serve the community (Short
Term).
8. Maintain viable law enforcement, fire protection and EMS capabilities (Continuing).
9. Identify facilities that can be used for mass care and sheltering and equip them for
managing large numbers of people (Short Term).
10. Improvement and maintenance of water shed and flood protection (Continuing).
Plan Adoption and Amendment
This plan and any major amendments to the plan shall occur only after an official Public Notice
has been posted in a local publication announcing a Public Hearing on the matter. After the
public has had the opportunity to review the proposed amendments the McGregor City Council
may, by resolution, choose to accept any amendment to the plan. Any and all amendments made
to this plan should be shared with the Clayton County Emergency Management Agency and the
Iowa Department of Homeland Security and Emergency Management Division.
Continued Public Participation
In order to ensure that the public remains involved in the future implementation of this plan a file
shall remain on hand at the McGregor City Hall. Copies of this plan shall be made available to
any party who requests to see it. Furthermore, if the City intends to make amendments to the
plan, a posted public notice should be made available so that the public can be made aware.
Public notice should also be posted for any meetings that deal with the amendment of this plan.
Said meetings are to remain open to the public.

Evaluation And Review Process
The City of McGregor will do a formal Update of their Hazard Mitigation Plan for submission to
the Federal Emergency Management Agency for review every five years. In addition the City of
McGregor has developed a method to ensure that an annual review and update of the Local
Hazard Mitigation Plan occurs. The city has formed a plan evaluation committee that consists of
local agencies, elected officials, emergency management officials, local economic development
officials, McGregor Fire, Police and EMS Departments and local citizens who is responsible for
organizing the meetings. The meeting will be held annually in December. The plan evaluation
committee is responsible for monitoring and evaluating the progress of the mitigation strategies
in the plan as well as how to consider and integrate the plan into other plans.
Copies of the Plan and the Committee’s review will be available at the McGregor City Hall.
Following the Planning Committee’s completion of the review process, the findings of the
annual review and recommended changes, if applicable, will be presented during the City
Council meeting. A public meeting will be held at that time.
The evaluation and review process will be conducted in accordance with the guidelines of
Worksheets 1, 2, 3, 4 and 5 of the FEMA Local Hazard Mitigation Review Crosswalk as found
in Appendix 7, page 196.

HAZARD MITIGATION PLANNING MEETING
Time: 1900-2100
Location: McGregor City Hall
MARQUETTE/MCGREGOR HMGP MEETING #1
16 JUNE 2008
MCGREGOR CITY HALL
The meeting began promptly at 7 p.m. Sign in sheets were explained and passed around as
introductions were made. Copies of the agenda were distributed to all present. Consultant Steve
Meyer advised the FEMA recommended guidelines include eight meetings in order to develop a
hazard mitigation plan, but the committee is only required to hold three. He has never needed to
conduct more than four meetings. Consultant Meyer followed that with the comment that once
the plan is complete it will be sent to FEMA and FEMA will send it back for changes before
their approval. Changes will be made and the plan will be resubmitted to FEMA for approval.
It was discussed that both cities (Marquette and McGregor) have mitigation plans but only to
state standards, not FEMA approved plans. Consultant Meyer comments that he is unsure why
the plans were not taken to the FEMA level. Consultant Meyer explains to the attendees that the
purpose of the planning process is to identify hazards in the community and identify mitigation
measures. In three cases, Consultant Meyer has taken the hazard mitigation planning process to
the next step, applying for and receiving grant funds for a community to complete a hazard
mitigation project following approval of their hazard mitigation plan. The plan itself will need
some background information including population information, number of fire calls, number of
EMS runs, etc. Some and those attending tonight may need to be contacted in order to get the
necessary information. The planning process is funded by federal grant with a 75% federal
match, 10% state match and 15% local match. The local match (15%) can be a soft match
consisting of attendance time and should not cost the community any money. All meeting time,
information gathering time, and review time will be documented and utilized. The contract for
planning services is $5,000.00.
Consultant Meyer began the process by first working with the attendees to identify hazards that
have impacted or could impact your community. The discussion followed the Hazard Analysis
Form provided by Consultant Meyer. Consultant Meyer advised that FEMA requires all 16
natural hazards be addressed but the others are voluntary. He recommends the group review and
discuss these additional hazards at minimum. There will be a compilation of hazards identified
and a scoring of those hazards. Some of the hazards discussed have historical links and others do
not. The group continued through the analysis process addressing only within the city corporate
limits. Once the hazards were identified, they were prioritized by high priority, medium priority,
low priority and not worth mentioning. Discussion was held throughout the identification and
prioritization process. It was noted in discussion that Marquette is in need of an evacuation plan
and potentially hazard mitigation project grant funds for bridging and roadways. Consultant
Meyer stated that he and Robyn Reese would complete the scoring/rating process. The next step
once the hazards are rated is to come up with possible mitigation measures for each hazard.
154
November, 2008
The group went through the mitigation measures included in their current mitigation plans. It
was noted which had been addressed and which still needed to be addressed since the plan was
completed. Consultant Meyer commented that if any studies had been conducted in the recent
past, those recommendations should be included in the hazard mitigation plan. It was noted that a
10x10 box culvert had been put in McGregor only. Back up generation was discussed for critical
services including city police and fire. McGregor has its own electric utility. Marquette does not
and is in need of generators.
In closing the first meeting, Consultant Meyer handed out a list of Mitigation Measures and
asked everyone to look over the list and mark any applicable ones. Once completed, each person
should submit their list to City Managers Norman Lincoln or Mary Anne Trudo within the next
two weeks. Norman and Mary Anne will submit those they collect to Consultant Meyer.
Consultant Meyer encouraged everyone to speak up if there are ideas that are not included in the
list as it could mean future grant funds for the community.
Consultant Meyer stated this planning process is on the fast track with scheduled completion by
the end of the calendar year. The next meeting will be held in August or September.

MINUTES OF OCTOBER 15, 2008
CITY OF MCGREGOR HMP MEETING
Time: 1900-2000
Location: McGregor City Hall
The meeting began promptly at 7 p.m. Consultant Meyer passed around the sign in sheet and the
McGregor synopsis. He reviewed the process up to this point. Originally the plan was to be
completed by the end of the year. Five to six weeks ago, Consultant Meyer was contacted by
FEMA Hazard Mitigation Specialists in Des Moines asking if he could complete both Elkader
and McGregor plans in a hurry. Consultant Meyer advised, he got busy and presented the
Elkader plan September 18th. Following that, he committed himself fully to McGregor Hazard
Mitigation Plan and sent out a completed draft by email last week. The draft plan has 205 pages.
Consultant Meyer advised the committee that the goal tonight is to make sure that everything is
in the McGregor plan that the committee wants included. This draft, with committee
recommendation, will be presented to the City Council for approval tomorrow night. Once it is
approved there, it will be sent on to FEMA in Des Moines for review and then on to FEMA
Region VII for approval. Norm Lincoln inquired as to the status of the old plan. Consultant
Meyer replied it was completed but was not DMA 2000 compliant to meet FEMA approval.
Consultant Meyer informed the group there would be similarities between the McGregor plan
and the Marquette plan due to shared services and area. The major difference will be found in the
dam hazard identified in McGregor and the rail transportation incident hazard identified in
Marquette. Consultant Meyer passed around a hard copy of the McGregor Hazard Mitigation
Plan. He explained that the real focus of the plan is the mitigation measures with everything else
being background information. There are 91 mitigation measures identified in the McGregor
plan. Consultant Meyer had sent out an electronic copy by email to all committee members last
week. There is a lot of redundancy within the plan; however that is to be expected. Randy Grady
commented there is mention of barricades under Highway Transportation Incident however that
is not enough as they are needed to keep vehicular traffic out, not only pedestrians. Consultant
Meyer inquired as to whether the EMS section had been reviewed. Burt Walters replied he had
reviewed that section. Consultant Meyer asked Fire Chief Dan Bickel if he had reviewed the fire
section. Chief Dan Bickel replied he had not had time to review it. Norm Lincoln advised that on
page 94, referring to hazmat, Northern Ag Services is referenced and it should be Agri-Bunge.
Consultant Meyer commented that Kris Eulberg of McGregor Utilities had already advised him
of this and it had been changed. Consultant Meyer asked Norm Lincoln and Tom Meyer if
everything regarding storm water and flood control included that they wanted. Norm Lincoln
advised it looked like it was all there. Kris Eulberg had provided Consultant Meyer with general
edits that he appreciated very much. Trudy Balcom commented that the plan seems to focus on
single hazard events and does not look at multiple events or when one event causes another.
Consultant Meyer advised that during the hazard analysis process multiple events or events
causing other events are considered. This is caused the Cascading Events Matrix and is used to
score and rank hazards. Randy Grady commented that during discussion on communications
failure, backup generators for the fire station in McGregor and the police station in Marquette
were discussed. Consultant Meyer advised those are included under energy failure. Randy Grady
requested they be included under communications failure as well. Trudy Balcom inquired as to
whether the plan was a shopping list. Consultant Meyer explained there were benefits to having
identified needs in the hazard mitigation plan and this could help with other grants outside of
176
November, 2008
FEMA. Norm Lincoln commented that FEMA grants are based on cost benefit analysis and the
trouble with McGregor is not enough structural damage expense to qualify for grant money. Dan
Bickle inquired as to if it is not in the plan then there is no chance of getting FEMA grant money.
Consultant Meyer replied that is a possibility or it may require a plan update. Consultant Meyer
added he is still unsure as to why FEMA wants the McGregor plan done so quickly. Norm
Lincoln advised McGregor filed for storm water expense reimbursement under Public Assistance
after the last disaster. That may be the reason. Dan Bickle asked if copies will be presented to all
committee members once the plan is approved by city council. Consultant Meyer replied once
the plan is approved by FEMA, he will provide one hard copy and 1 electronic copy to the city.
Dan Bickle inquired as to why tornado was ranked higher than communications failure.
Discussion was held on the scoring and rating process. Consultant Meyer reminded the
committee they are only required to include natural hazards so hazards such as communications
failure are not required and will not be evaluated by FEMA. However their inclusion makes for a
more well rounded plan. It helps to raise awareness and to help lend credibility to other grant
requests such as Assistance to Firefighter Grants. Norm Lincoln asked if this was addressed in
the county plan and at what ranking. Consultant Meyer replied it is addressed in the county plan
but he does not remember the ranking. He did write a communications project application for the
county and is awaiting approval.
Consultant Meyer requested approval of the committee of the plan as drafted if he includes the
changes discussed to present to the city council. A motion of approval was made by Dan Bickel.
Tom Sinclair seconded the motion and it was carried with all ayes.
Consultant Meyer advised the committee that the FEMA Hazard Mitigation Specialists placed in
Des Moines are there to review the plans before they are sent to FEMA Region VII. They may
push the plan back if they find any issues with it.
The plan presented and approved tonight is on the McGregor City Council Meeting agenda for
Thursday, October 16, 2008 at 8:00 pm.
Consultant Meyer asked the committee if this had been a worthwhile process. Dan Bickle replied
it had been eye opening and made him think. Consultant Meyer asked if there were
improvements that could be made in the process he uses to develop a hazard mitigation plan.
Norm Lincoln commented that they have plans but they don’t necessarily use them when the
event happens at 3am. Consultant Meyer advised the planning process is often more worthwhile
than the final plan itself. Randy Grady commented the situation often dictates as it goes. Burt
Walters commented there is a lot of diversity for a small town and he has all volunteer
responders. Dan Bickle added this has been a smooth process. Consultant Meyer stated he
appreciates all of the feedback and all of the work people in the community have done to provide
information for the hazard mitigation measures and hazard profiles. The assistance really helps to
narrow down and extract the information to build the plan. He can put together 95% of the plan
without the meetings however the most important fst 5% of the plan requires the meetings and
interviews.
The meeting was adjourned at 8:00 pm.

Worksheet #2: Evaluating Your Planning Team
When gearing up for the plan evaluation, the planning team should reassess its composition and ask the
following questions:
YES
Have there been local staffing changes that would warrant inviting different members to the planning team?
Comments/Proposed Action:
Are there organizations that have been invaluable to the planning process or to project implementation that should
be represented on the planning team?
Are there any representatives of essential organizations who have not fully participated in the planning and
implementation of actions? If so, can someone else from this organization commit to the planning team?
Are there procedures (e.g., signing of MOAs, commenting on submitted progress reports, distributing meeting
minutes, etc.) that can be done more efficiently?
Are there ways to gain more diverse and widespread cooperation?
Are there different or additional resources (financial, technical, and human) that are now available for mitigation
planning?
If the planning team determines the answer to any of these questions is ―yes,‖ some changes may
be necessary.
