Lake County, Illinois, is subject to natural hazards that threaten the life, health, and safety of
residents and visitors. Natural hazards have caused extensive property damage throughout the
County and can be expected to cause more damage in the future. In recent years:
� Major flood events struck the County in187Q.1882.188@.1883.1888.2OOO.2OO4.2OO8and
2013�
.
�Sixteen tornadoes have touched down since 1A57;

The update of the ANHMP was based on discussion and data provided by the
participating municipalities as they followed the recommended 1 O-step planning process.
An ANHMP introduction and a description of the planning process are presented in
Chapters 1 and 2. Natural hazards that can impact Lake County have been assessed in
Chapter 3. Goals and guidelines established by the HMPC are presented in Chapter 4.
Six mitigation strategies and a capabilities assessment of Lake County are examined in
Chapter 5. The ANHMP action plan is detailed in Chapter 6, and procedures for
monitoring and maintaining this ANHMP are included in Chapter 7.

Planning Process
The HMPC followed a 1 0-step planning
process to update the ANHMP. The
HMPC met three times from June to
October 2016. The HMPC reviewed the

property, considered a variety of ways
to reduce and prevent damage, and
recommended the most appropriate
and feasible measures for
implementation. Existing plans and
programs were reviewed during the
planning process. It should be
underscored that this ANHMP does not
replace other planning efforts, such as
Lake County Comprehensive
Stormwater Management Plan. This
ANHMP complements those efforts.
The public was invited to participate
through several concurrent means,
including the HMPC meetings, online
surveys,Ra,ner surveys press releases_
newsletter articles, and the Lake
County website. A public meeting was
held on October 21, 2016 at the Lake
County Administration Building in
t WKWUAK
period extended from October 21 to
November 21, 2016.
The AMPC reviewed all potential natural hazards that could impact Lake County, and
evaluated them based on their causes, their likelihood of occurring, and their impact on
people, property, critical facilities, and the local economy. The information was based on
ayaila�la t6chnical stviiies ai54 ra�#Ks Wy th&-paKicipating agencies ai-4 otmmynities an4
on their past experiences. The table below shows the natural hazards that are the focus
of this ANHMP and provides a summary of the hazards' potential impact on Lake County's
health and safety, total assets, and economy from the risk assessment.

Hazard Mitigation Goals and Guidelines
The qoals of the ANHMP were reviewed and reaffirmed bv the HMPC. The ANHMP aoals
Goal 1, Protect the lives, health, and safety of the people of Lake County from the
impact and effects of natural hazards.
Goal 2. Protect public services, utilities and critical facilities from potential damage
from natural hazard events.
Goal 3: Mitigate existing buildings to protect against damage from natural hazard
events.
Goal 4. Ensure that new developments do not create new exposures of people and
property to damage from natural hazards.
Goal 5. Mitigate to protect against economic and transportation losses due to
natural Wazards.
Hazard gation Strategies
The HMPC then considered mitigation strategies for the natural hazards shown on page
ES-4. The HMPC reviewed current preventive mitigation measures being implemented
by the County and municipalities. Preventive measures include activities such as building
codes and the enforcement of the Lake Countv Watershed Develooment Ordinance. Lake

Mitigation Action Plan
The action plan outlines the recommended activities and initiatives to be implemented
over the next five years. It is understood that implementation is contingent on the
availability of resources (staff and funding). The action plan identifies those responsible
for implementing the action items, and when they are to be completed.
There are 33 action items included in this ANHMP update. The first two action items are
administrative. The first action item calls for the formal adoption of this ANHMP. Formal
adoption is a requirement for recognition of the ANHMP by mitigation funding programs.
The HMPC will provide the mechanism and a vehicle for the ANHMP to be implemented,
monitored, evaluated and updated, and for continued public involvement. The HMPC will
report to the County Board and municipal councils and boards, annually, and participate
in the next five-year update.
The other action items are mitigation program items. Many are ongoing activities of
stormwater management and emergency management offices and agencies. The action
items were prioritized by the HMPC based on action that they felt should be implemented
countywide and which each municipality should undertake. Below is a list summarizing
the action items included in Chapter 6. Action items are also presented as community -
specific action items in Chapter 6.

jurisdictional ANHIVIP to meet federal mitigation planning requirements. This ANHIVIP
updated the examination of natural hazards facing Lake County, establishes mitigation
goals, evaluates and highlights the existing mitigation activities underway in Lake County,
and recommends a mitigation action plan for the County and municipalities to undertake
in the next five years. The mitigation efforts included in this ANHIVIP are for protecting
people, property and other assets of Lake County. Some action items are ongoing efforts;
