Grand County
Grand County, located in southeastern Utah, was founded in 1890 with a population
estimated in 2016 at 9,579 (United States Census 2016 Quick Facts). Named for the
Colorado River—then known as the Grande River—the county is bounded by the Green
River on the west and the state of Colorado on the east, covering a total area of
3,671.54 square miles according to the National Conservation Resource Service (NCRS).
Grand County’s natural features include its namesake river, which runs through its
southeastern corner; Arches National Park just north of Moab in the south; and the
northernmost portion of Canyonlands National Park in the southwest corner. The
county seat is Moab City which, along with Castle Valley Town, are the two incorporated
areas. Other communities include Thompson Springs, the Moab suburb of Spanish
Valley, and Cisco—a ghost town with a population of approximately 10.

Introduction
Mission
The Grand County Pre‐Disaster Natural Hazard Mitigation Plan was created with the
goal of substantially and permanently reducing the County’s vulnerability to natural
hazards through sound public policy. By increasing public awareness of potential harm,
documenting resources for risk reduction and loss‐prevention, and identifying activities
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
6
to guide the development of less vulnerable and more sustainable communities, the
Pre‐Disaster Natural Hazard Mitigation Plan aims to protect citizens, critical facilities,
infrastructure, private property, and the natural environment.
Plan Review and Update 2018
After an extensive review to incorporate the most current demographic data, maps,
vulnerability assessments, and mitigation projects, this 2018 Grand County Pre‐Disaster
Natural Hazards Mitigation Plan (PDM) has been created to update the original PDM
plan created in 2003, updated in 2013, which was approved by the county, the state,
and FEMA. The review incorporates the revision of names, critical facilities, hazard
history, and economic development throughout the region over the previous five years.
Other changes include a reorganization of the mitigation goals, objectives, and actions
for ease in reading and for more clearly identifying projects. There have been some
minor changes to appendices and general maintenance parts, however there were no
changes to background history and data which continues to accurately reflect the
region.
Organization
As with the original Pre‐Disaster Mitigation Plan (PDM), this updated version was
developed and organized within the rules and regulations established under CFR Title
44, Part 201.6. Contained within the plan is a consideration of the purpose and
methodology used in developing the plan, as well as a profile of communities within the
county, and a vulnerability analysis of nine potential natural hazards. Several appendices
are included to provide further detail on specific elements of the above content. This
plan is intended to create a foundation that will enable Grand County and the
communities within Grand County to develop projects that provide for both the safety
of their populations and the protection of the environment.
Plan Financing
The Grand County Pre‐Disaster Natural Hazard Mitigation Plan was financed and
developed under the Pre‐Disaster Natural Hazard Mitigation Program guidelines
established by the FEMA and the Utah Department of Public Safety Division of
Emergency Management.
Plan Participation
The 2018 Grand County Pre‐Disaster Natural Hazards Mitigation Plan was completed
through the collaborative efforts of the Utah Department of Public Safety Division of
Emergency Management, Grand County Emergency Manager, Fire Departments, Grand
County Sheriff’s Office, Public Works Department, Planning Commission, Assessor’s
Offices, City, County, and State GIS Departments, Elected Officials, Public Employees,
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
7
Utah Division of Forestry, Fire and State Lands, and Citizens of the cities and towns
within Grand County. Feedback was solicited through the Grand County Pre‐Disaster
Natural Hazard Mitigation Plan Working Group during the plan development. Public
participation was also encouraged through a public hearing and review of the 2018 PDM
Plan on the Grand County website. All comments, questions, and discussions resulting
from these activities were given thoughtful consideration as the plan was developed.
Purpose
This plan exists to identify natural hazard threats to the community, prepare mitigation
management strategies to address those threats, develop short‐term and long‐term
goals and objectives for mitigation planning, and to fulfill federal, state, and local hazard
mitigation planning obligations. The intention of this plan is to enhance awareness of,
and provide mitigation strategies for, elected officials, agencies, and the public, develop
actions which will minimize negative outcomes to Grand County’s citizens, the economy,
and the environment due to potential natural hazard threats. The well‐being of the
county and local communities’ rests on reducing risks to life and property in the event of
a natural hazard event.
Community Capabilities
Grand County and the municipalities of Moab City and Castle Valley Town face many
challenges to improve the natural hazard mitigation efforts and sustain the Grand
County Pre‐Disaster Natural Hazards Mitigation 2018 Plan. The following capabilities
have been identified for consideration for discussion and strengthening to implement
and sustain the plan.
Financial:
Grand County nor Moab City or Castle Valley Town maintain a natural hazard mitigation
specific fund or funding mechanism. Grand County, Castle Valley Fire Protection District
and the Moab Valley Fire Protection District do participate in the Utah Wildland
Suppression Fund and has developed the Community Wildfire Preparedness Plan
(Appendix 8). The CWPP does provide for some mitigation funding for Urban Wildland
Interface fire reduction programs. The challenge as acknowledged in the Grand County
General Plan is 95% of the county is owned by other Federal, State government agencies
or is Tribal land and only 5% of the county is providing the tax base for county and
municipal services. Additionally, there is very large portion of the County that is not
served by any of the Fire Districts. The two‐fire protection special service districts have
their own taxing authority and governing boards. The Thompson Springs Fire
Department serves the towns of Crescent Junction and Thompson Springs but is limited
by volunteers to the point that they generally do not have enough staff to respond. The
County does have a Memorandum of Understanding (MOU) with the Lower Valley Fire
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
8
Protection District based in Loma, Colorado to provide some limited service into the
Utah portion of the I‐70 corridor.
Planning and Technical Services:
The planning and technical capabilities of Grand County and the municipalities are
impacted by the limited tax base as the hiring of professional staff is often unobtainable.
The elected officials and appointed staff perform many of the tasks normally completed
by professional staff members. An example of a technical shortfall is that within Grand
County there is not currently a GIS trained staff member. The county and municipalities
will contract out for specific planning documents such as Master Plans, General Plans,
and Zoning Ordinances. The Southeast AOG is an organization the county can reach out
to for assistance with planning and technical services.
Administration:
Grand County has an elected seven‐person County Council and an appointed County
Council Administrator. The emergency manager is also overseeing the special projects
such as the jail remodeling, county communication system, assisting the County Public
Safety Answering Point (PSAP) dispatchers, and is responsible for the Community
Wildfire Preparedness Plan. The county has three full time building inspectors and one
full time staff person. The County provides the building inspection services for the City
of Moab and the north part of San Juan County under contracts with these entities. This
department also oversees the flood plain management program for the County. The
County has a full‐time staff for planning and zoning duties. The elected Sheriff provides
law enforcement services throughout the county and unincorporated towns with a
limited staff. The fire and EMS first responders are a mixture of paid staff and volunteers
along with the County Search & Rescue organization within the county. The county does
maintain a Public Works/Road Department.
Moab City and the Town of Castle Valley have an elected mayor and city council and
Moab has a city administrator. The City of Moab does support a small police
department. The City of Moab has a Public Works and Roads Department along with a
Planning & Zoning Department and is considering hiring its own full time building
inspector.
The ability of Grand County and the municipalities to expand the funding opportunities,
roles and responsibilities beyond the current capability of implementing and sustaining
the Pre‐Disaster Natural Hazards 2018 Plan is constrained by the limited tax base.

Scope
The plan provides comprehensive natural hazard identification, risk assessment,
vulnerability analysis, mitigation actions, and an implementation schedule.
Grand County Plan Goals and Objectives
The goals of the Pre‐Disaster Natural Hazard Mitigation Plan include coordinating with
local governments to develop Grand County plans and processes that meet the planning
components identified in the FEMA Region VIII Crosswalk document, as well as Utah
DEM planning expectation, and public input from the local community. The overall
objective is risk reduction from natural hazards in the State of Utah through
implementing and updating county, regional, and the State of Utah mitigation plans.
Short Term Goals:
These goals form the basis for the development of the Pre‐Disaster Natural Hazard
Mitigation Plan and are shown from highest to lowest priority.
1. Protection of life before, during, and after the occurrence of a natural
disaster.
2. Preventing loss of life and reducing the impact of damage where problems
cannot be eliminated.
3. Protection of emergency response capabilities (critical infrastructure).
4. Protect and/or create communication and warning systems.
5. Protect emergency medical services and medical facilities.
6. Ensure mobile resource availability and survivability.
7. Ensure the continuity of government.
8. Protect developed property, homes and businesses, industry, educational
institutions and the cultural fabric of the community. While utilizing hazard
loss reduction within the community’s environmental, social and economic
needs.
9. Protect natural resources and the environment, when considering mitigation
measures.
10. Promote public awareness through education of community hazards and
mitigation measures.
11. Preserve and/or restore natural features.
Long Term Goals:
1. Eliminate or reduce the long‐term risk to human life and property from
identified natural hazards.
2. Aid both the private and public sectors in understanding the risks they may
be exposed to and find mitigation strategies to reduce those risks.
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
10
3. Avoid risk of exposure to identified natural hazards.
4. Minimize the impacts of those risks when they cannot be avoided.
5. Mitigate the impacts of damage because of identified natural hazards.
6. Accomplish mitigation strategies in such a way that negative environmental
impacts are minimized.
7. Provide a basis for funding; prioritizing of natural hazard mitigation projects.
8. Establish a county platform to enable all the communities to take advantage
of shared goals and resources.
Objectives:
The following objectives are meant to serve as a measure to evaluate natural hazard
mitigation projects. The criterion becomes especially important when two or more
projects are competing for limited resources.
1. Identification of persons, agency or organization responsible for implementation.
2. Project a time frame for implementation.
3. Explanation of how the project will be financed including the conditions for
financing and implementing (as information is available).
4. Identifying alternative measures, should financing not be available.
5. Be consistent with, support, and help implement the goals and objectives of
natural hazard mitigation plans already in place.
6. Projects should significantly reduce potential damages to public and/or private
property and/or reduce the cost of state and federal recovery for future
disasters.
7. Projects should have practical, cost‐effective, and environmentally sound
alternatives after options are considered.
8. Projects should address repetitive problem(s), or one that has the potential to
have a major impact on a critical facility.
9. Projects should meet applicable permit requirements where development in
hazardous areas is avoided.
10. Projects should contribute to both the short and long‐term solutions to the
hazard vulnerability risk problem assuring the benefits of a mitigation measure is
equal to or exceeds the cost of implementation.
11. Projects should have manageable maintenance and modification costs when
possible.
12. Projects should accomplish multiple objectives including improvement of life‐
safety risk, damage reduction, restoration of essential services, protection of
critical facilities, and security of economic development, recovery, and
environmental enhancement whenever possible.

Authorities
Federal:
Public Law 93‐288 as amended, established the basis for federal hazard mitigation
activity in 1974. A section of this Act requires—as prerequisite for state receipt of future
disaster assistance outlays—the identification, evaluation, and mitigation of hazards.
Since 1974, many additional programs, regulations, and laws have expanded on the
original legislation to establish hazard mitigation as a priority at all levels of government.
Several additional provisions were also included when PL 93‐288 was amended by the
Stafford Act that provide for the availability of significant mitigation measures in the
aftermath of a Presidentially declared disaster. Civil Preparedness Guide 1‐3, Chapter 6‐
Hazard Mitigation Assistance Programs places emphasis on hazard mitigation planning
directed toward hazards with a high impact and threat potential.
The Disaster Mitigation Act of 2000 (DMA 2000) was signed into Law on October 30,
2000 by President Bill Clinton. Section 322, defines mitigation planning requirements for
state, local, and tribal governments. Under Section 322, if states submit a mitigation
plan (a summary of local/regional mitigation plans) identifying natural hazards, risks,
vulnerabilities, and proposed actions to reduce those risks and vulnerabilities, the state
is eligible for an increase in the Federal share of hazard mitigation.
State:
The Governor’s Emergency Operation Directive, The Robert T. Stafford Disaster Relief
and Emergency Assistance Act, amendments to Public Law 93‐288, as amended, Title 44,
CFR, Federal Emergency Management Agency Regulations, as amended, State
Emergency Management Act of 1981, Utah Code 53‐2, 63‐5, Disaster Response
Recovery Act, 63‐5A, Executive Order of the Governor, Executive Order 11, Emergency
Interim Succession Act, 63‐5B.
Local:
Effective natural hazard mitigation is dependent upon local governments assuming a
vital role. As such, each local government will review all present or potential damages,
losses, and related impacts associated with natural hazards to determine what is
required for mitigation action and planning. For Grand County and the Cities and Towns
of Grand County, the local executives responsible for implementing plans and policies
are the Grand County Council and City or Town Mayors. It is critical that local
governments be prepared to participate in the post‐disaster Hazard Mitigation Team
process, as well as the pre‐mitigation planning outlined in the Pre‐Disaster Natural
Hazard Mitigation Plan.

Demographics and Population Growth
Demographics provide a way of understanding both the stability of a community
(through determining the degree of change within the community [see Table 1] and
showing the ethnic diversity within the community [see Table 2], as well as potential
impacts any natural hazard may have. To that end, the following information regarding
Population, Population Estimates, and Development Trends is provided.
In recent years, Grand County has seen a slight increase in population. According to the
2010 census, the population was 9,225, while the 2016 population count was estimated
at 9,579. Over 50% of the population lives in the county seat of Moab City on the
southern edge of the county. According to the 2010 census the population of Moab City
was 5,062, while the 2016 census count was estimated at 5,242. Due to its proximity to
nearby Arches and Canyonlands national parks, Moab attracts a large number of tourists
during the year who uses the town as a base for hiking and climbing, mountain biking
adventures along an extensive network of trails, including Slickrock Trail, and the off‐
roading at the annual Moab Jeep Safari.

Economy
Tourism is the heart of Grand County’s economy. Visitors from around the world travel
to the area to take advantage of mountain biking, rock climbing, jeep tours, river
running, and the natural beauty of Arches and Canyonlands National Parks. In addition
to tourism and recreation, the county has begun expanding the economy, moving
forward by focusing on light manufacturing, the fine arts, educational programs,
television and film production, agriculture, and the development of natural resources.
As of December 2016, the unemployment rate for the county was 5.8 percent, with

Transportation and Commuting Patterns
Interstate 70 (I‐70) and U.S. Highway 191 provide the principle transportation routes
through Grand County. I‐70 runs east‐west through the center of the county to the
Colorado border. U.S. Highway 191 is the north‐south corridor through the county,
travelling south from Crescent Junction off I‐70 through Moab City and into San Juan
County. State Route 128 parallels the Colorado River from US Highway 91 in Moab,
crossing the Colorado River at Dewey and joining I‐70 west of the Colorado border.

Land Use
The early 1950’s saw the rise of uranium mining in Grand County, leading to a jump in
population to nearly 10,000 over three years. Potash, salt mining, and milling
operations provided additional sources of economic prosperity. However, since the
1990’s, the primary economic driver has been the tourism industry. Over 1 million
visitors annually (according to Grand County History) visit the area to enjoy access to
outdoor recreation such as mountain biking, river rafting, rock climbing, hiking, and off‐
road motorsports. Federal and State agencies including the Bureau of Land
Management (BLM), the Forest Service (FS), the National Park Service (NPS), and the
Utah Divisions of Forestry, Fire and State Lands (FFSL) own and maintain most of the
county’s land.

The guiding document for current land use and future development since the 2013 Pre‐
Disaster Mitigation Plan is the 2012 Grand County General Plan Update. The number of
residential building permits over the last five years (Table 4) reflects a steady increase in
growth for Grand County. The growth has occurred primarily as single‐family residences,
townhomes, as overnight rentals. There are three major hotels and a convention center
under construction scheduled for completion by 2019. The new developments fill in
areas identified in the general plan and adhere to Grand County Flood Plain Ordinances
and the adopted Building Code. The Grand County Building Inspector also provides the
building inspection services to the City of Moab and is the Grand County Flood Plain
Manager. Construction within identified problem soils areas require an engineering
study be submitted to the building inspector.
The 2012 Grand County General Plan Update clearly states the priorities for
development includes open space for the 100‐year flood plain and geologic hazard
areas. These priorities have been and will continue to be implemented by Grand County.
The following list of priorities represent the priority level of each type of open space.
The types of open space with the highest priority are encouraged to be set aside first to
achieve development incentives, followed by the lower priority types of open space.
#1 Riparian Areas ‐ A riparian area is a plant community contiguous to and affected by
rivers, streams, drainage‐ways or lakes that supports an ecosystem that is distinct from
the surrounding areas not affected by hydrologic features.
# 2 100‐Year Floodplain – The 100‐year floodplain includes any land area along a river,
stream, or drainage way that is susceptible to inundation. The 100‐year floodplain is an
area with a 1% probability of a flood occurring in any given year.
#3 Trail Corridors ‐ Ready access to public lands contributes greatly to quality of life and
prosperity in Grand County. Historic routes as well as new opportunities for accessing
public lands were identified as a top priority for open space.
#4 Ridgelines – The FLUP focuses on ridgelines viewed from major public rights of way:
US Highway 191, State Road 128, Mill Creek Road, Spanish Valley Drive and La Sal Loop
Road. Skylines and prominent ridgelines in the foreground that define the natural form
of the landscape are the highest priority for protection.
#5 Agricultural Land ‐ Agricultural land uses include the cultivation of plants and raising
of animals useful to humans.
#6 Historic or Archeological Sites ‐ Physical evidence of the county’s history and pre‐
historic human settlement.
#7 Geologic Hazard Areas ‐ Geologic hazards include rock‐fall, landslides, debris flows,
avalanches, expandable/ collapsible soils, and unstable slopes.

Risk Assessment
The following risks were identified through the risk assessment process conducted by
the Grand County Pre‐Disaster Natural Hazard Mitigation Working Group: Drought,
Flood, Wildfire, Severe Weather, Landslide, Earthquake, Problem Soil, Dam Failure, and
Infestation. The Grand County Pre‐Disaster Natural Hazard Mitigation Group conducted
a further review of the identified hazards to establish probability, severity, and county
ranking.
The Risk Assessment methodology for developing this updated plan included several
steps to gather information from the whole community, prepare the input, analyze and
discuss the data to provide information of the potential impacts of the nine natural
hazards identified for Grand County. The Grand County Working Group primarily used
available GIS maps for the identified natural hazards, historical data, local knowledge,
and the potential impact on the critical facilities and infrastructure. The gathered
information was shared with the appropriate subject matter experts for their review
and input. The final compilation of data was discussed by the Working Group and the
Risk Assessment for each of the nine identified natural hazards was reached by
consensus of the Working Group.

Grand County Critical Facilities
The Grand County Critical Facilities List was updated by the Grand County Pre‐Disaster
Natural Hazards Mitigation Working Group and coordinated through the Grand County
Emergency Manager.
Natural Hazard Impact Legend:
Grand County’s summary for the risk assessment for all the critical facilities by hazard (DF = Dam
Failure, DR = Drought, EQ = Earthquake, FL = Flood, IN= Infestation, LS= Landslide, SW= Severe
Weather, PS= Problem Soils, WF= Wildfire).
Each hazard has its own criteria for risk:
Wildfire categories of Very, Very Low (VVL), Very Low (VL), Low (L), Low‐Moderate (L‐M),
Moderate (M), Moderate‐High (M‐H, High (H), Very High (VH), Extreme (E), and Urban,
Agriculture, Water, or Barren (W).
(DNR for the Utah Wildfire Risk Assessment Portal has identified)

Application, Moab Hazard Mitigation Plan, and Utah DEM Flooding HAZUS
Report 2016.
Description of Location and Extent
Regarding streams and rivers (Pack, Mill, Placer, Castle, Onion, Professor, Kane—
tributaries to the Colorado River—and Tusher creek, a tributary to the Green River)
creates a very high flood threat. Over half of the City of Moab is in a floodplain and
subject to flash flooding from frequent thunderstorms and cloudbursts that occur in the
steep slickrock canyons. Local roads, infrastructure, and residences are subjected to
repeated flooding at Walker Canyon, Stewart Canyon, the Kelling Property, and Williams
Way.
Since Moab City is the county seat and the largest community in the county, it has been
designated as a Project Impact Community. As such, the Moab City Storm Water Master
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
26
Plan was created to identify flood control issues and put in place provisions for Pack
Creek, Mill Creek, and the Colorado River.
Castle Valley is vulnerable to flooding in severe concentrated rain events, when the
water comes over a longer period the multitude of drainages can handle the water quite
well, however more and more isolated cloudbursts are affecting Castle Valley in very
destructive short‐lived storms.
The Town of Castle Valley does not have a second exit that can handle the volume of
traffic that Castle Valley Drive does now. This creates a situation of significant isolation
and safety concerns.
Currently the Town of Castle Valley is not participating in the National Flood Insurance
Program.
Vulnerability Assessment
The impact of a 100‐Year flooding event on Grand County would likely see at least
moderate damage to 56 buildings with 9 destroyed. 27 additional buildings would
suffer minimal damage and at least two schools would suffer moderate damage or
greater. Financial estimates for building‐related losses are 23.02 million dollars, there
would be approximately 189 displaced households and 284 persons will be seeking
public sheltering. (Hazus‐MH: Flood Global Risk Report, October 2017)

Grand County and Moab City Floodplain Administrators
The Grand County Floodplain Administrator is responsible by Ordinance to enforce the
provisions of the Grand County Flood Damage Prevention Ordinance 526 adopted
September 2014. The Grand County Floodplain Administrator has developed and
submitted to FEMA a proposed revision of the Pack Creek Floodplain area as an update
to the FEMA Flood Insurance Rate Map. The County is waiting for the approval from
FEMA. (Grand County Website December 2017)
The Moab City Floodplain administrator has been enforcing the provisions of the Moab
City Floodway Zoning Ordinance 17.33. The Ordinance was successfully updated and
adopted November 2017.

Grand County Pre‐Disaster Hazard Mitigation Plan 2018

Description of Location and Extent
Five hazard categories were assigned by the Division of Forestry, Fire, and State Lands to
the wildfire risk data provided in the statewide fire risk assessment—Extreme, High,
Medium, Low, and Very Low. These ratings are based on the type and density of
vegetation in each area (although factors influencing wildland fire behavior such as
weather conditions, wind speed, and direction are not considered in this risk
assessment) and cover all Grand County. For a history of wildfires in the county in the
years 1984‐2018 refer to Table 14.
Vulnerability Assessment
In order to complete loss estimates, wildland fire areas of extreme, high, and moderate
risk within the county were identified and then overlaid with vulnerable areas drawn
from a GIS database. Table 10 shows the population and number of both commercial
and residential structures within Grand County that lie inside extreme, high, and
moderate wildfire risk areas.
Table 10 Structures and Population in Wildfire Area
Potential Wildfire Loss Estimates
Annual sales for the businesses inside each wildfire risk area as well as the assessed
value of residential property are included in Table 11. Contents are not included in
residential loss estimates (doing so would increase the values listed by 50%). No
businesses in Grand County are in the Extreme wildfire risk areas.
Table 11 Inventory of Properties Located in Wildfire Risk Areas in Grand County

Catastrophic Wildfires Cascading Effects
The occurrence of a Catastrophic Wildfire in Grand County is fortunately a rare event.
The post fire effect may produce a cascading series of events requiring immediate action
and mitigation. The effect on the water shed may impinge upon the County or
Communities’ wells, springs, and the water delivery system. There may be landslides,
mudflows, and debris flow in the burn scar that may impact streams and reservoirs or
damage infrastructure such as roads and power transmission lines. Awareness of the
potential and considering a plan of action to implement if a Catastrophic Wildfire should
occur may mitigate the effects on the County and Communities of the cascading series
of events.

Location
Landslides generally, occur in canyon mouths and foothill areas. Manti‐La Sal National
Forest, near foothills on steep slopes, cliff faces, canyon walls.
Seasonal Pattern or
Conditions
Spring and Summer usually caused by the stress release of over‐weighted soils and or
loosening of rock and debris.
Duration
Landslides generally last hours or days, but some can last weeks.
Analysis Used Information and maps provided by UGS, DEM, AGRC.
Description of Location and Extent
The map “Grand County Landslide Hazard” shows the locations of high‐risk landslide
areas by identifying historical landslide locations. The main historical landslides in Grand
County occurred in the Southeastern portion of the Manti‐La Sal National Forest, just
east of Green River. Generally, landslides are in well‐defined, localized areas. The
identified historical areas will most likely be the location of future landslides.
The impacts of Rockfall/Landslides on the community of Castle Valley would depend on
the location and severity of the event. Rockfalls can cause damage to structures, roads,
and can alter drainages which could negatively impact other properties and roads.
Rockfalls will mostly happen higher up on the rim side of the valley.
Vulnerability Assessment
The hazard analysis indicates that there are no business or critical facilities in Grand
County that are located within the high landslide risk area. There are residential units as
well as general infrastructure within the risk area (Tables 15,16).

Soils type map from the City of Moab Storm Water Master Plan
Explanation of Soil Types:
The hydrologic soil group is a general indication of a soil’s infiltration capacity and is a
key determinant of runoff behavior. The Natural Resources Conservation Service (NRCS)
has classified soils into four hydrologic groups: A, B, C, and D. Soils of group A have the
highest infiltration rate and therefore produce the least amount of runoff. Group A soils
include permeable gravels and well‐drained sands. Group B soils have moderate
infiltration rates and moderately fine or coarse textures. Developed portions of each
study area were assumed to have a minimum of nonnative group B soils to represent
the desert landscaping common on developed parcels. Group C soils have a lower
infiltration rate and finer textures, sometimes with a layer that impedes infiltration.
Soils of group D have the lowest infiltration rate and produce the highest amount of
runoff. Group D soils include fine silts, fine clays, and other soils with low infiltration
Grand County Pre‐Disaster Hazard Mitigation Plan 2018

rates. Soil groups are described in TR-55 (NRCS, 1986). Soil data were retrieved from
the Natural Resource Conservation Service’s (NRCS) Web Soil Survey. Some map units
defined in the soil data required the use of the Soil Survey of Grand County to determine
corresponding curve numbers (Soil Conservation Service, 1989).
Group A soils are the most prevalent in the City of Moab.

Analysis Used Review of information and maps provided by County soil classification books,
Soil Conservation Service, local input, USGS, DEM, and AGRC.
Description of Location and Extent
To determine runoff conditions, the Soil Conservation Service (SCS) investigated the
Canyonlands area, just south of the Grand County border. The soil makeup of the area
ranged from well‐drained silty soils to impervious rock, and SCS found permeability in
the bluffs of the southeastern portion of the county to be generally moderate, setting
the stage for conditions of medium to rapid runoff. In the Moab City Developed area,
SCS findings show the soil to have moderate to rapid permeability indicating slow to
medium runoff. In the mid‐southern portion of the county SCS found minor amounts of
silica dune, while expansive soil and rock affect the central and southern portions of the
county.
In September 2015, a sinkhole developed in Moab City. As a result, one home was
condemned. According to the Grand County Building Inspector, “sinkholes typically
occur naturally because of percolating water and the gradual removal of soluble
bedrock. This process creates a void that ultimately results in a collapse of the overlying
cave roof. Though most often occurring in regions with heavy limestone deposits,
sinkholes also appear in areas of chalk, gypsum, basalt, and where there are underlying
salt beds.
“Human activities such as mining, groundwater over‐extraction, drainage diversion and
failing infrastructure – such as water main leaks, or the collapse of sewer systems and
other buried pipes – can also create sinkholes”.
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
43
Present day subsidence and sinkholes have yet to make a significant impact on the
Castle Valley community however the larger concern could be directed at the reason
why they appear or increase in size. Many of the activities that are responsible for
creating sinkholes could be very detrimental to the holistic health of Castle Valley. Over‐
mining water in the valley could lead to drought and seriously impact the community.
Other activities such as mining in the region could affect Castle Valley’s Sole Source
Aquifer if sinkholes begin to appear from mining practices.
Table 17 shows the results from an analysis in which the problem soils and major
roadways map developed for the State of Utah and a map of Census block data were
overlaid to indicate where households and roadways were in relation to problem soil
areas (no households were identified in problem soil areas). Potential roadway
replacement was calculated assuming a cost of $5 Million per mile. Areas of problem
soils within Grand County are indicated by the map “Grand County Problem Soils.”

Analysis Used Utah Water Rights Dam Safety, Bureau of Reclamation and DWR
Description of Location and Extent
Downstream uses, size, height, volume, and incremental risk/damage assessments
determine hazard ratings, which are: Low‐insignificant property loss; Moderate‐
significant property loss; High‐possible loss of life. For the record, dam safety hazard
classifications are only in the event of a dam failure. Just because a dam is classified as a
high hazard does not mean there is a high failure probability. See Table 18.

Vulnerability Assessment
A high hazard threat to Grand County comes from Ken’s Lake Reservoir. While Ken’s
Lake Dam is in San Juan County, the risk is in both San Juan and Grand Counties. Built in
1981, the dam is owned by the Grand County Water Conservancy District. The reservoir
storage at spillway crest is 2,820 acre‐feet and the reservoir storage at dam crest is
2,620 acre‐feet. The dam’s spillway type is open channel and the maximum dam breach
flow is 64,000 cfs with a 3‐square mile drainage basin area. A failure of Ken’s Lake Dam
would have a major effect on Moab City, 6 miles away and the first downstream town.
Because of this potential, the possible failure of Ken’s Lake Dam in San Juan County
raises the magnitude for Dam Failure to critical for Grand County.

Vulnerability Assessment
The historical record indicates Grand County, The City of Moab, and the Town of Castle
Valley experience a wide variety of severe weather from thunderstorms with heavy
rainfall and lightning, tornadoes, dense fog, hail, and heavy snowfall. The heavy rains
impact the transportation system with road flooding causing road damage and road
closures in the County, City of Moab, Town of Castle Valley and the National Parks.

Description of Location and Extent
Countywide; Grand County, the City of Moab, and the Town of Castle Valley are in the
southeast climate division of Utah and are affected with periodic drought events. The
culinary water supply, irrigation water, and stock ponds are depleted during the drought
events. Grand County has signed a Drought Disaster Declaration in April 2018 and
resigned each month since. The drought has impacted the economic, social, and
environmental fabric of Grand County.
Vulnerability Assessment
Grand County is located on the Colorado Plateau an historically arid area of the State of
Utah. There have been 10 recorded drought events since 2002 according to the National
Weather Service records. Grand County is currently in the 11th drought event
categorized as a Severe Drought event.

Description of Location and Extent
Grand County continues to experience an infestation problem of insects, disease, and
noxious weeds. The unhealthy forests are conducive to insect and disease issues.
Several factors contribute to the decline in forest health including: lack of active
management, poor grazing patterns, fire exclusion, and invasive/noxious weeds.
Vulnerability Assessment
Infestation will continue to be an issue in the future because of Grand County’s climate.
The drought conditions, invasive weeds, insects, and species diversity are all affected by
climate and will continue to be a limited problem for Grand County’s forestlands and
communities.
Adequate precipitation and growing space is necessary to maintain tree vigor, thereby
increasing tree resistance to insects and disease. The drought conditions persistent in
Grand County continues to place more stress on the forests already in poor health. The
associated insect and disease issues may not be the cause of poor forest health but a
result of it.

Natural Hazard Disaster History
Identifying past natural hazard events is key in predicting where future events are likely
to occur. The following available relevant information such as date, location, area
affected, and impacts are identified in the table below (Table 19). Due to the frequency
and geographic extent of problem soil, and some severe weather events past events
have not been recorded and are therefore not identified in the table below.

Goal Priority for mitigation actions are: High, Medium, or Low. It is possible that
economic, environmental, and even political relations may cause conditions to this type
of priority system to change. As such, goal priorities are only used to understand that
ensuring the project is completed is of greater urgency than others. For these purposes,
Objective is a general statement of the project(s) to be completed, and the Action is the
specific mitigation project. The prioritization high, medium, low for each goal and
associated action project was established based on the perceived need, ability to
support the action project, and cost of the action project. The Grand County Working
Group, Subject Matter Experts (SMEs), and the Grand County Emergency Manager
finalized the priority of each action project.
High: Priority goal and project to complete.
The project can be supported.
A portion of the funding is obtainable.
Medium: Would like to complete goal and project.
The project can be supported.
The funding is questionable.
Low: Nice to complete the goal and project.
May be able to support the project.
Funding may not be available.

Goal 1: Priority High
Objective 1: FL1 To mitigate the effects of hillside floods and to improve storm
drainage conveyance throughout the City of Moab.
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
75
Action projects:
FL1.
Several projects included: Moab area canyon projects including
Stewart Canyon, Johnson Canyon, Tusher Canyon, and Walker
Canyon. Moab southwest hillside drainage projects. Dam and
check dam projects. Storm drainage improvement projects.
Time Frame: 2018‐2023
Funding: Federal funds from FEMA., Transportation
Enhancement and others, State hazard Mitigation
funds, Utah Department of Transportation and
City funds
Estimated
Cost:
$7,000,000
Staff: Contracted work with some in‐kind help
Background Much of the City of Moab is in the 100 and 500‐
year floodplains due to creek and hillside
flooding. Damage to Moab properties frequently
occurs from hillside flooding because the flows
are not adequately attenuated nor properly
conveyed to a safe area of discharge. The City,
County, and Federal Government have built dams
in an attempt to mitigate damage. Tusher
Canyon and Walker Canyon now have detention
ponds. However, there are needs for more hillside
flooding mitigation in other areas especially in
Stewart Canyon and Johnson Canyon. Additional
areas of concern exist north of Stewart Canyon
along the highway. In these areas, large flows are
concentrated and released mostly unimpeded
into populated areas. In order to best address
these flows, storm drainage conveyance is
necessary to safely convey these flows to an area
where they can be discharged safely.
Goal 2 Priority: High
Objective 1: FL2 Continue to support and update the Grand County
Storm Drain Master Plan.
Action project: FL2 Review and revise the Storm Drain Master Plan as
development warrants.
Location: Countywide
Time Frame: Ongoing
Funding: Local
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
76
Estimated Cost: $120,000
Staff: County Staff, Private
Contractors
Background The Storm Drain Master
Plan protects the County
from flood losses. The Plan
also contains identified
storm water basins and
other structural control
projects.
Countywide Problem Identification: The continued development in the county has
caused a need to continually re‐evaluate the system and update the Storm Water
Management Plan to effectively manage storm water. Development also directly
impacts the historical drainage ways with culverts, roads, and structures.
Goal 3 Priority: High
Objective 1: FL3 Encourage 100% Participation in the National Flood
Insurance Program (NFIP)
Action project: FL3 Assist Unincorporated Areas of Grand County to
participate in the NFIP by creating outreach documents
promoting flood insurance and include educational
materials in local newspaper(s), on the county social
media sites, libraries, and in other public buildings.
Location: Unincorporated Portions of
Grand County
Time Frame: 2018‐2020
Funding: Local
Estimated Cost: 8,000.00
Staff: County Emergency
Manager, County Engineer,
State Flood Plain Manager
Background Special Flood Hazard Areas
have been identified by
FEMA in the
Unincorporated areas of
the County.
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
77
Countywide Problem Identification: Participation in the Nation Flood Insurance
Program is available but underutilized by eligible participants residing in the identified
flood plains.
Objective 4: FL4 Support updating of flood hazard data
Action project:
FL4
Support and encourage Grand County to develop a Pack Creek
flood map modification program.
Time Frame: Ongoing
Funding: Federal
Estimated
Cost:
Unknown
Staff: County Engineer and State Floodplain Manager
Background Accurate flood maps assist the County in the
administration of the pack creek flood way and
better reflects flood risk within the County.
County shall continue to regulate construction
within the Pack Creek flood way. Ninety five
percent of the population in the County is
exposed to Pack Creek flood area to include Moab
City. To have this project accomplished this
would protect the majority of Grand County
population.
Countywide Problem Identification: Moab City’s Water Reclamation Facility (WRF) serves
all the City of Moab, Grand County in Spanish Valley, and potentially San Juan County
within Spanish Valley. The plant is in the Colorado River floodplain and has several
components that are below the Base Flood Elevation.
Goal 2: Priority High
Objective 1: FL5 Mitigation to protect Moab City’s WRF from floodwaters of the
Colorado River.
Action project:
FL5
Provide berms, pumps, and/or the rising of component walls to
prevent floodwaters from Colorado River from inundating Moab
City’s WRF.
Time Frame: On‐Going
Funding: Funding sources may include FEMA or other
mitigation grants, local funding from Moab City or
Grand Water and Sewer, or state department of
water quality.
Estimated
Cost:
$14,000,000
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
78
Staff: Contracted work design and construction of flood
control features.
Background Moab City’s WRF is located within the 100‐year
floodplain for the Colorado River. Based on the
current configuration, the elevations of several of
the plant’s components are below the river’s base
flood elevation. A berm was placed around the
plant in 1996, but it is not sufficiently tall to
prevent the inflow of floodwater onto the facility.
The plant serves a current population of over
10,000 residents including all the City of Moab,
Grand County in Spanish Valley. In addition to the
residents, a couple million visitors come to the
area every year. This WRF is the only public
treatment plant in Grand County. A major flood
event would cause contamination of the river as
well as rendering the WRF temporarily inoperable
and potentially causing considerable damage to
the facility.
Countywide Problem Identification: Grand County initiates projects through the
Community Impact Fund Board (CIB) for capital improvements. The following projects
are those that mitigate flooding problems in the county and unincorporated areas.
These projects are from the Permanent CIB list and are for the terms 2013‐ 2018 and
2018‐2023.

Appendix 1
Plan Maintenance, Evaluation, and Implementation
Monitoring, Evaluating, and Updating the Plan
Periodic monitoring and updates to this Plan are required to ensure the goals and
objectives for the Grand County Pre‐Disaster Mitigation Plan 2018 are kept current and
the mitigation strategies are being carried out. This Plan has been designed to be user‐
friendly in terms of maintenance and implementation. This portion of the plan outlines
the procedures for completing such revisions and updates. The Plan will also be revised
to reflect lessons learned or to address specific hazard incidents arising out of a disaster.
The Grand County LEPC meets quarterly to review emergency management efforts
within the county. This meeting is open to the public and attended by County and City
governmental officials, local businesses, EMS, hospitals, fire departments, and local
citizens. To keep the Grand County Pre‐Disaster Mitigation Plan 2018 up‐to date the
LEPC will conduct an annual review to discuss the incorporation of new hazards,
mitigations, or other data into the Plan.
Annual Review Procedures
Grand County will annually review the mitigation strategies described in this plan or as
situations dictate, such as following a disaster declaration. The process will include
Grand County Emergency Manager organizing a Pre‐Disaster Hazard Mitigation Planning
Working Group comprised of individuals from organizations responsible for
implementing the described mitigation strategies. Progress towards the completion of
the strategies will be assessed and revised as warranted. The Grand County Emergency
Manager will regularly monitor the Plan and is responsible for making revisions and
updates.
Five Year Plan Review
The entire Plan including, background studies and analysis shall be revised and updated
every five years by the participating jurisdictions to determine if there have been any
significant changes in the County that would affect the Plan.
Increased development, increased exposure to certain hazards, the development of new
mitigation capabilities or techniques, and changes to State or Federal legislation are
examples of changes that may affect the applicability of the Plan.
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
88
The Grand County Pre‐Disaster Hazard Mitigation Working Group will be reconstituted
for the Five‐Year Review/Update Process. Typically, the same process that was used to
create the original Plan will be used to prepare the update.
If the participating jurisdictions or the Utah Division of Emergency Management
determine the recommendations require modifications, an amendment may be initiated
as described below.
Plan Amendments
The State of Utah Division of Emergency Management Hazard Mitigation Officer,
members of the Local Hazard Mitigation Working Group, County Emergency Manager,
or County Council Members/Mayor/City Manager of an affected jurisdiction may initiate
amendments and updates to the Plan.
Upon initiation of an amendment to the Plan, the Grand County Emergency Manager
will forward information on the proposed amendment to all interested parties including,
but not limited to, all affected county and city departments, residents and businesses.
Depending on the magnitude of the amendment, the full Hazard Mitigation Planning
Working Group may be reconstituted.
At a minimum the information will be made available through a public notice in a
newspaper of general distribution within the county providing a comment period of no
less than forty‐five days.
At the end of the comment period, the proposed amendment and all review comments
will be forwarded to participating jurisdictions for consideration. If no comments are
received from the reviewing parties within the specified review period, such will be
noted accordingly. The Utah Division of Emergency Management will review the
proposed amendment along with comments received from other parties and submit a
recommendation to FEMA within sixty days.
In determining to recommend approval or denial of a Plan amendment request, the
following factors will be considered:
1. There are errors or omissions made in the identification of issues or needs during
the preparation of the Plan
2. Contemporary issues or needs have been identified which were not adequately
addressed in the Plan
3. There has been a change in information, data, or assumptions from those which
the Plan was based
4. The nature or magnitude of the risks have changed
5. There are implementation problems such as technical, political, legal, or
coordination with other agencies
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
89
Upon receiving the recommendation from the Utah Division of Emergency
Management, a public hearing will be held by the Grand County Emergency Manager.
The Division of Emergency Management will review the recommendation (including the
factors listed above) any oral or written comments received at the public hearing.
Following the review, the Division of Emergency Management will take one of the
following actions:
1. Adopt the proposed Amendment as presented
2. Adopt the proposed Amendment with modifications
3. Defer the Amendment request for further consideration and/or hearings
4. Reject the Amendment request
Implementation Through Existing Programs
Once the Plan has been promulgated, participating cities and the County will be able to
include this Plan’s information in existing programs and plans. These could include the
General or Master Plan, Capital Improvements Plan, Emergency Operations Plan, State,
County, and/or City Mitigation Plans. Many of the mitigation actions developed by the
cities and county have mitigation elements of other programs such as the National
Flood Insurance Program, the Utah Wildland‐Interface Code, the Building Code
Effectiveness Grading System, and the Community Rating System.
Process
It will the responsibility of the participating jurisdiction’s political body to ensure that
these mitigation projects are carried out no later than the target dates unless
reasonable circumstances prevent their implementation. (i.e. Lack of funding)
Funding Sources
Although all mitigation techniques will likely save money by avoiding future losses,
projects may be costly to implement. The County and participating jurisdiction will
continue to seek funding sources to assist funding the completion of mitigation projects.
This portion of the Plan identifies primary Federal and State Grant Programs, local and
non‐governmental funding sources.
Federal Programs
The following Federal Grant Programs have been identified as funding sources which
specifically target hazard mitigation projects:
The Pre‐Disaster Hazard Mitigation Program administered by FEMA. The program
provides funding to States, Counties, and Cities for cost effective hazard mitigation
activities that complement a comprehensive mitigation program that reduces loss of
life, reduces injuries, or damage to property.
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
90
The funding is based on a 75% Federal Share and a 25% Non‐Federal Share. The Non‐
Federal Share may be in the form of cash or in‐kind or a combination. The following
maybe eligible mitigation activities:
1. Pre‐Disaster Mitigation Planning
2. Technical Assistance (i.e. risk assessments, project development)
3. Mitigation Projects
4. Acquisition or relocation of vulnerable properties
5. Hazard Retrofits
6. Minor structural hazard control or protection projects
7. Community outreach and education
The Flood Mitigation Assistance Program is provided by FEMA and administered by the
State. The program provides funds to reduce or eliminate the risks of long term flood
damage to structures insurable under the National Flood Insurance Program. The
funding is available for mitigation planning and the implementation of mitigation
measures only. The funding levels are a 75% Federal Share and 25% Non‐Federal Share.
State Grant Programs
Local Funding
Local government depends on property taxes as a primary source of revenue. These
taxes are typically used to finance services that must be available and delivered on a
routine, regular basis to the public. If local budgets permit these funds may be used as
matching funds for State and Federal Grants.
Non‐Governmental Funding
Another potential source of funding for implementing mitigation projects are monetary
contributions from private sector companies, faith‐based organizations, charities, or
other non‐profit organizations.

Appendix 2
Grand County PDM Planning Process
Integrating the 2018 Grand County Pre‐Disaster Natural Hazards
Mitigation Plan into other County, City, and Town Plans
The most direct application for local jurisdictions is to create or update a natural hazards
zone or overlay in the local General Plans, zoning, and land use ordinances. Regulating
land uses in natural hazard areas can effectively reduce losses of life and property.
Communities should be updating their General Plan about every five years at a
minimum anyway. This regular update process is a great opportunity for communities to
review their sections of the Grand County Pre‐Disaster Natural Hazards Mitigation Plan
2018, identify risks documented in the plan, and to update their local General Plan,
zoning, and ordinances accordingly.
The responsibility and authority to regulate development in natural hazard areas lies
with the County, City, or Town. The State of Utah does not regulate most development,
and while the Utah Geological Survey and others offer assistance to
Counties/communities, they do not have authority to regulate. Public health, safety, and
welfare can be protected most effectively as communities exercise the authority given
them and use the resources available to them to plan development responsibly near
hazard areas.
Local emergency management officials train for emergency response to all types of
natural hazards. This plan can serve as a reference to them providing historical hazard
events, points of contact, general geographic locations of hazards, and potential losses
per jurisdiction per hazard. Also, continued involvement in several follow‐up Pre‐
Disaster Mitigation planning meetings will provide useful forums for discussion and
collaboration among various organizations and levels of government.
Public Works and Roads Departments can also implement the information from this
plan. As communities view the natural hazards data and mapping in this plan, they can
accordingly identify where infrastructure could be damaged in the event of a natural
disaster or where weak sections are in the various systems. Data sets for the various
hazards identified in this plan are continually being updated and refined. The Utah
Geological Survey and others can provide zoning and ordinance assistance for geological
hazard areas and can provide the most up‐to‐date data and mapping.
As far as Flood Mitigation Plans, those communities that do have a plan can update it
referencing the data and statistics in this plan. Potential losses and the general number
of structures in FEMA floodplains can be very beneficial in those plan updates. However,
the best resource for updating floodplain planning efforts is the Utah Division of
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
92
Emergency Management. The State Floodplain Manager has the necessary training and
resources to assist communities in this respect. Likewise, for wildfire protection, the
Utah Division of Forestry, Fire, and State Lands can aid communities which can help
them become eligible for funding. The cooperative and collaborative development of
the Community Wildfire Preparedness Plans and the Pre‐Disaster Natural Hazard
Mitigation Plans enhances the community’s preparedness for all‐natural hazards. For
general pre‐disaster mitigation funding and project assistance, the Utah Division of
Emergency Management hazard mitigation planning staff can provide the most up‐to‐
date knowledge and experience.
Perhaps the most direct way communities in Grand County can implement this plan into
current planning mechanisms is by completing the mitigation strategies for their
respective community found in this plan. These strategies were written by the Grand
County Working Group comprised of representatives from throughout the county to
find ways to decrease potential losses to life and property. As communities strive to
improve natural hazards planning within their jurisdictional boundaries, they will more
effectively protect the public’s health, safety, and welfare by implementing these
mitigation strategies.
Grand County 2018 Pre‐Disaster Natural Hazard Mitigation Planning
Process Overview
The Grand County 2018 Pre‐Disaster Natural Hazard Mitigation Plan update began after
a Request for Proposal and a bid award with the selection of Scott Mabe LLC, a Disabled
Veteran Small Business, as the contractor to work with and assist Grand County with
updating the Grand County 2013 Pre‐Disaster Natural Hazard Mitigation Plan. The
contractor hired Ron Mosher of Ron Mosher Consulting, a sole proprietorship, to assist
the contractor with the task.
The Kick‐Off Meeting was held on 6/27/2016 chaired by the Grand County Emergency
Manager, Rick Bailey and the San Juan County Emergency Manager, Kelly Pehrson,
attended by Tammy Gallegos, Deputy San Juan County Emergency Manager, Angelia
Crowther, State of Utah Division of Emergency Management Southeastern Utah Liaison,
Scott Mabe, Lead Contractor, and Ron Mosher, Contractor. The purpose of the meeting
was to brainstorm the composite of the 2018 PDM Working Groups for Grand County
and San Juan County. A tentative meeting schedule was discussed for each county. The
roles and responsibilities of the contractor and the county were discussed and agreed
upon.
As a result of this Kick‐Off Meeting the Grand County 2018 Pre‐Disaster Natura Hazard
Mitigation Plan Working Group and Grand County Core Planning Team were identified.
The invitations to participate in and attend the first Grand County 2018 Pre‐Disaster
Grand County Pre‐Disaster Hazard Mitigation Plan 2018

The first Grand County 2018 PDM Working Group Meeting was held on 10/03/2016
facilitated by the contractor. The key stakeholders were present, and the current 2013
Grand County Natural Hazard Pre‐Disaster Plan was reviewed to establish what basic
information required updating. The participants were asked, based on their knowledge
and experience, for input to begin the process of updating some areas of the plan. Their
spontaneous responses were recorded for inclusion in the plan as they recalled various
activities that had occurred over the past 5 years. Jim Pringle, the NOAA weather
representative offered to research and provide a severe weather history update for
Grand County. Jason Johnson, Area Supervisor, State of Utah Forestry, Fire, and State
Lands agreed to obtain the 2012‐2017 Grand County Fire Records from the Salt Lake City
Office and provide them to the contractor. Mayor Dave Erley, The Town of Castle Valley,
informed the Working Group that Castle Valley had recently completed their own Pre‐
Disaster Natural Hazard Mitigation Plan and it had been approved by FEMA Region 8. He
requested the Town of Castle Valley’s 2015 Pre‐Disaster Natural Hazard Mitigation Plan
be an Appendix to the Grand County Plan and suggested Jazmine Duncan would be a
valuable asset to the Working Group as she was involved in the Castle Valley planning
process. The contractor began working with the Grand County Emergency Manager to
develop a current list of Grand County critical facilities and identify which of the natural
hazards impacted each facility. The contractor was tasked with researching and
updating the basic county descriptive and demographic information. The contractors
began contacting members of the Grand County 2018 PDM Working Group to assemble
information from their respective jurisdictions and departments to complete the plan.
The process of sharing information with the Grand County Emergency Manager was
agreed upon to keep the county involved in every step of developing the plan.
The second Grand County Working Group Meeting was held on May 31, 2017 and was
facilitated by the contractor. The basic Plan information that had been gathered by the
contractors was reviewed and comments made by the participants were incorporated
into the document. The status of current mitigation projects and potential future
mitigation projects with points of contact were discussed. The contractor was assigned
to follow up through the Grand County Emergency Manager to document future
mitigation action projects proposed by the subject matter experts and insert them into
the plan. A review of existing plans and ordinances was conducted to determine if there
have been any changes with particular attention to flooding and flood plain issues. The
flood plain manager indicated the following ordinances were up to date and being
enforced. The Grand County Storm Water& Flood Control Ordinances 13.12.010 thru
13.12.060, the 2014 Grand County Flood Damage Prevention Ordinance and the City of
Moab Updated Code 17.33 Floodway Zone Ordinance. The updated severe weather
information gathered by Jim Pringle, NOAA, was shared with the contractors and
incorporated into the plan. The issue of how to cooperate and collaborate with the
development of the Community Wildfire Preparedness Plan (CWPP) was discussed. The
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
97
consensus was to include the CWPP an appendix in the Grand County Pre‐Disaster
Natural Hazard Mitigation Plan when the CWPP was completed. The identification and
prioritization of the natural hazards affecting Grand County, municipal jurisdictions, and
the critical facilities were discussed and agreed upon by the Working Group.
During the interim between the second and third Grand County Working Group
Meetings information flowed between the contractors, the Grand County Emergency
Manager and the members of the core planning group as the impacts of the natural
hazards on the respective jurisdictions were identified and hazard mitigation action
projects were developed and prioritized for presentation to the Working Group. The
October 2017, Hazus Earthquake Risk Report and October 2017, Hazus 100‐year Flood
Risk Report for Grand County provided by the State of Utah Division of Emergency
Management establish the basis for the vulnerability assessments for the flood natural
hazard profile and the earthquake natural hazard profile. The Grand County Storm Drain
Master Plan provided the mitigation action projects for the Grand County Roads based
on the priorities established in the plan. The Grand County General Plan provided
guidance for prioritizing mitigation projects related to wildfire along Mill Creek and Pack
Creek. The General Plan specifically indicates the number one priority is maintaining the
riparian areas along the creek beds which influenced the development of the mitigation
action plans to reduce ladder fuels and build defensible space along the creek beds.
The third Grand County Working Group Meeting was held on March 6, 2018 and the
contractors presented a Draft 2018 Grand County Pre‐Disaster Natural Hazard
Mitigation Plan for review and comment by the Working Group. The contractor
facilitated a point by point review of the document seeking additional input from the
Working Group. The Working Group suggested some modifications which were
incorporated into the plan. The Working Group endorsed moving onto the next step of
the process, the public hearing.
The Grand County 2018 Pre‐Disaster Natural Hazard Mitigation Plan was posted on the
Grand County website on November 21, 2017 by Matt Ceniceros, Grand County IT, and
each version update added to the site for citizen review and comment. There were no
comments from the community. The Public Hearing Notice was posted in five public
locations, following Grand County policy, on July 19, 2018 and the Public Hearing was
held on July 30, 2018. There were no citizens in attendance and no comments were
received in person or electronically.

APPENDIX 4
Environmental Considerations
Natural disasters are any major, adverse event which occurs from the natural
meteorological, hydrologic, or geologic processes of the Earth. These events can include
floods, severe weather, volcanic eruptions, and earthquakes. Any natural disaster can
result in loss of life or property damage, often with concomitant economic damage. The
affected population’s resilience or ability to recover will impact the severity of any
economic damage.
Natural disasters are an integral part of the environment’s capacity to maintain balance.
Over millions of years, the processes of wind, water, and geology have shaped Utah as
we know it, and they will continue to do so—affecting humans and their structures. This
meeting of natural events and human communities is what constitutes a natural
disaster, and while modern engineering has made it possible to mitigate some of the
effects of natural disasters, the potential for economic and environmental costs can be
high. Human tampering with natural systems can also create an imbalance in the
environment which might create problems in the future which cannot yet be seen. As
such, it seems living with a small amount of risk (respecting the natural processes as
much as possible), rather than constructing mitigation for every eventuality, might be
best in the long run.
In order to work harmoniously with the environment, nature’s own mitigation measures
need to be identified, protected and/or strengthened. In addition, all applicable city
codes, county codes, and state and federal laws pertaining to the environment must be
followed, doing the utmost to ensure that our environment is not harmed through
mitigation measures. In the main, mitigation programs proposed in this plan will be
funded through federal, state, or local programs/funding. During the planning process,
the following acts were evaluated, and their consideration and incorporation was
deemed necessary while organizing and implementing the PDM plan.
The Clean Air Act (CAA) 1970: The Clean Air Act is the comprehensive Federal Law that
covers the entire country under the Environmental Policy Act (EPA) regulating air
emissions from area, stationary, and mobile sources. This law sets limits or National
Ambient Air Quality Standards (NAAQS) on how much of a pollutant can be in the air
anywhere in the United States, this controls the emissions of air pollutants. These limits
ensure that all Americans have the same basic health and environmental protections.
Maximum pollutant standards were set, and states may have stronger pollution controls
on an individual basis, but not weaker pollution controls than those set for the whole
country.
Each state explains how it will do its job under the Clean Air Act by developing a
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
149
mandated “state implementation plan” (SIP) that must be approved by EPA. The 1977
amendment was to set new dates for areas of the country that failed to meet the initial
deadlines for achieving NAAQS. The 1990 amendments addressed problems such as acid
rain, ground‐level ozone, stratospheric ozone depletion, and air toxics. This act required
that facilities with copious amounts of certain hazardous chemicals to have special
emergency planning requirement; based on a facilities potential threat or risk from
chemical spills, fires, explosions, etc. A Risk Management Plan (RMP) is prepared that
includes hazard identification, assessments, design, and maintenance of a safe facility;
necessary steps to prevent releases and ways to minimize the consequences from an
accidental release (Clean Air).
The Clean Water Act (CWA): The Federal Water Pollution Control Act Amendments of
1972 came about because of the growing awareness for controlling water pollution. As
amended in 1977, this law became known as the Clean Water Act whose mission is to
establish the basic structure for regulating discharges of pollutants into the waters of
the United States, and to reduce and maintain the chemical, biological, and physical
veracity. The act gave the Environmental Protection Agency (EPA) the authority to set
wastewater standards for industry.
The act also required that each state adopt water quality standards, act to protect
wetlands, and limit industrial and municipal discharges into navigable waters unless
permitted. It funded the construction of wastewater treatment plants for nearly every
city in the United States, under construction grant programs from the EPA and
recognized the need for planning for future problems that posed a threat from nonpoint
source pollution (Clean Water).
Endangered Species Act of 1973: This act provides a plan for the protection of
threatened and endangered plants and animals and the habitats in which they are
found. Congress finds and declares that various species of fish, wildlife, and plants in the
United States have been caused to become extinct, or are so depleted in numbers they
are in danger of becoming extinct, because of economic development and expansion
without adequate concern for conservation. Aesthetic, ecological, educational,
historical, recreational, and scientific importance come from these species and are a
value to our nation and its people.
The U.S. will conserve, to a practicable extent, the species that face extinction and will
encourage the States through federal assistance to develop and maintain conservation
programs. The reason for the Act is to provide a means in which ecosystems with
endangered and threatened species will be conserved. It is also declared that all state
and local agencies resolve water resource issues in connections with conservation of
endangered species (Endangered).
Floodplain Management Policy: The main points of the policy are to reduce the loss of
life and property and the disruption of societal and economic pursuits caused by
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
150
flooding or facility operations as well as to restore, sustain, and enhance the natural
resources, ecosystems, and other functions of the floodplains. Activities will search for a
balance between the, sometimes competing, uses of floodplains in a way that makes
the most benefit to society. To pursue and encourage appropriate use of floodplains and
to avoid long and short term negative impacts associated with the inhabitants and
modification of floodplains and to avoid direct and indirect support of floodplain
development, whenever there is a practicable alternative.
“Functions (Natural) of floodplains include natural moderation of floods; fish, wildlife,
and plant resources and habitat; groundwater recharge; and water quality maintenance.
Uses of floodplains include the following: storm water management, erosion control,
open space, natural beauty, opportunity for scientific study, outdoor education,
recreation, and cultural preservation, and compatible economic utilization of floodplain
resources by human society” (Floodplain, Reclamation).
National Historic Preservation Act of 1966: This act was found and declared by Congress
because “the spirit and direction of the Nation are founded upon and reflected in its
historic heritage…the historical and cultural foundations of the Nation should be
preserved as a living part of our community life and development to give a sense of
orientation to the American people.” Some of the other main points of the act include
the awareness of historic properties that are being lost or substantially altered. The
preservation will continue a legacy of cultural, educational, aesthetic, inspirational,
economic, and energy benefits for future generations.
The knowledge of historic resources and the encouragement of their preservations will
improve the planning and execution of federal and federally assisted projects and will
assist economic growth and development. The act would like to use measures that will
foster conditions in which historic resources can exist in productive harmony with
present and future generations (National). Section 106 of NHPA “requires all Federal
agencies to take into account the effects of their actions on historic properties, and that
provide the Advisory Council on Historic Preservation (ACHP) with a reasonable
opportunity to comment on those actions and the manner in which Federal agencies are
taking historic properties into account in their decisions” beginning at the early stages of
planning to mitigate any adverse effects on historic properties (Section 106).
Utah’s Noxious Weed Control Act, July 2008: was established to provide a means to
control destructive noxious weeds. The act goes hand in hand with helping to
prevent wildfires as well as control insects that are both destructive to our economic
and environmental landscapes. The invasive noxious weeds can spread rapidly
causing enormous economic losses. It is reported that millions of acres in North
America have been invaded or are at risk of being invaded by weeds which include
destruction of cropland, pastures, rangelands, forests, wilderness areas, national
parks, recreation sites, wildlife management areas, transportation corridors,
waterways, wetlands, parks, golf courses, even yards and gardens. The Utah Weed
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
151
Control Association reports that the spread of noxious weeds is spreading at a rate of
more than 4,600 acres per day on federal lands in the United States.
Noxious weeds can cause damage to watersheds and increase soil erosion leaving
the land permanently damaged. The economic losses from weeds exceed $20 billion
annually in the United States, and the cost continues to grow. The mitigation efforts
in each county help protect and preserve our lands.

APPENDIX 5
General Mitigation Strategies
Section 1. Mitigation Categories
For the purpose of this mitigation plan, the mitigation strategies were divided into one
of six categories according to how they accomplish mitigation. Below are the categories
with examples; following, in Section 2, the regional natural hazard mitigation strategies
are addressed using this categorization.
A. Emergency Services
B. Natural Resource Protection
C. Prevention
D. Property Protection
E. Public Information and Involvement
F. Structural Protection
A. Emergency Service: Emergency Services protect people during and after a disaster.
Examples include:
• Mutual aid agreements
• Protection of critical facilities
• Health and safety maintenances
• Inventory of assets
• EMS/Police/Fire response and skill
B. Natural Resource Protection: Natural Resource Protection includes strategies that
preserve or restore natural areas or the natural function that an area provides.
Examples include:
• Wetlands protection
• Pollution reduction
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
155
• Erosion and sediment control
• Fuels reduction
• Watershed maintenance
C. Prevention: Prevention measures are intended to prevent the problem from
occurring and/or keep it from getting worse.
Examples include:
• Planning, zoning, and ordinance regulations
• Open space preservation
• Floodplain and wetland development regulations
• Storm water management
• Minimum set back requirements
• Evacuation plans
D. Property Protection: Property Protection measures are used to modify buildings
within high‐risk areas in an attempt to reduce damage. For the most part property
protection measures do not affect a buildings appearance of use making them less
expensive and particularly suitable for historical sites and landmarks.
Examples include:
• Utility relocation
• Burying or flood proofing
• Non‐structural earthquake mitigation
• Backup protections
• Insurance and other monetary loss minimization actions
• Technical evaluations and mapping
E. Public Information and Involvement: Public Information and Involvement activities
are intended to advise property owners, potential property owners, and visitors
about the particular hazards associated with a property and ways to protect people
and property from these hazards.
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
156
Examples include:
• Education
• NFIP
• URWIN areas
• Hazard Identification
• Maps with high hazard locations identified
• Informational mailings
• Workshops
• Real Estate disclosures for natural hazards
• Real Estate insurance
F. Structural Protection/Projects: are man‐made structures, which prevent damage
from impacting property.
Examples include:
• Detention/Retention basins
• Larger culverts
• Elevated seismic design
• Floodwalls
• Debris basins
• Landslide stabilization and levees
Section 2. General Mitigation Strategies
Flood/ Riverine Mitigation
Generic Mitigation: The following are generic mitigation strategies appropriate for
addressing the hazard of flooding. Many of these strategies are expanded upon in the
text that follows.
• Avoidance, land‐use planning and zoning ordinances
• Better flood routing through communities
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
157
• Annual warning of risk information on how to protect property and lives
• Flood insurance awareness, emphasis, and marketing
• Projects such as levees/dams
• Funding by a storm water tax in cooperation with Federal and State programs
• Additional SNOwpack TELemetry (SNOTEL) sites and enhanced instrumentation
• Protection of roads and bridges
• Greater reservoir capacities
• Curtail development in flood‐prone areas
• General infrastructure protection
• Develop river corridor parkways
• Protection of wastewater treatment facilities from excessive inflows
• Protection of drinking water supply systems
• Gather hazard and risk data/information
• Development of improved mitigation techniques
• Education of local officials, developers, and citizens
• Protecting natural floodplain resources
• Good watershed management
A. Emergency Services
Flood Warning: Warning systems designed to alert residence of rising floodwaters.
Warning systems can disseminate the information through many means such as sirens,
radio, television, mobile public‐address system, reverse 911, or door‐to‐door contact.
Multiple or redundant warning systems are most effective, giving people more than one
opportunity to be warned.
Flood Response: Flood response refers to the actions that are taken to prevent or
reduce damage once a flood starts, and example of flood response is the turning of
State Street into a river during the 1983 flood event. Many of the below actions should
be part of an emergency response plan EOP developed in coordination with the
agencies that share responsibilities. The EOP once developed should be exercised and
continually evaluated so when the plan is needed key players know what to do. Flood
response actions might include:
• Activation of the emergency operations center
• Sandbagging designated areas
• Closing streets and bridges
• Shutting off power to threatened areas
• Releasing children from school
• Ordering an evacuation
• Opening evacuation shelters
Critical Facilities Protection: Protecting critical facilities is vital, yet this protection draws
workers and resources away from protecting other parts of a town or county. For this
reason, listed below are vital facilities and facilities with the potential of causing a
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
158
secondary disaster if destroyed. It is important to keep these locations in mind with
considering potential mitigation projects.
Facilities or locations vital to flood response efforts:
• Emergency operations centers
• Police and fire stations
• Hospitals
• Highway garages
• Selected roads and bridges
• Evacuation routes
Facilities and locations, which if flooded would create a secondary disaster, applicable to
all disasters:
• Facilities housing hazardous materials
• Wastewater treatment plants
• Schools
• Nursing homes
Health and Safety Maintenance: Response to floods or other natural disasters should
include measures to prevent damage to health and safety such as:
• Patrolling evacuated areas to prevent looting
• Providing safe drinking water
• Vaccination of residents for tetanus
• Clearing streets
• Cleaning up debris
Many of these recommendations should be integrated into a public information
program to educate citizens on the benefits of health and safety precautions.
B. Natural Resource Protection
Wetlands Protection: Wetlands are capable of storing copious amounts of floodwater,
slowing and reducing downstream flows, and filtering the water. Any development that
is proposed in a wetland is regulated by either federal and/or state agencies. Mitigation
techniques are often employed, which might consist of creating a wetland on another
site to replace what would be lost through the development. This is not an ideal
practice, however, since it takes many years for a new wetland to achieve the same
level of quality as an existing one.
Erosion and Sedimentation Control: Controlling erosion and sediment runoff during
construction and on farmland is important, since eroding soil will typically end up in
downstream waterways. Sediment tends to settle where the water flow is slower, it will
gradually fill in channels and lakes, reducing their ability to carry or store floodwaters.
Sediment and erosion control have two principal components: minimize erosion with
vegetation and capture sediment before it leaves the site. Slowing runoff increases
infiltration into the soil, thereby controlling the loss of topsoil from erosion and the
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
159
resulting sedimentation. Runoff and erosion control can be done through vegetation,
terraces, contour strip farming, no‐till farm practices, and impoundments.
C. Prevention
Planning and Zoning: Land use plans are put in place to guide future development, they
recommend where development should and should not take place. Sensitive and
vulnerable lands can be designated for uses that would not be incompatible with
occasional flood events. The zoning ordinances can regulate development in these
sensitive areas by limiting or preventing some or all development.
Open Space Preservation: Preserving open space is the best way to prevent flooding and
flood damage. Open space preservation should not be limited to the flood plain. Other
areas within the watershed may contribute to controlling the runoff that exacerbates
flooding.
Floodplain Development Regulations: Floodplain development regulations typically do
not prohibit development in the special flood hazard areas, but they do impose
construction standards on what is built there. The intent is to protect roads and
structures from flood damage and to prevent the development from aggravating the
flood potential. Floodplain development regulations are generally incorporated into
subdivision regulations, building codes, and/or floodplain ordinances.
Subdivision regulations: These regulations govern how land will be divided into separate
lots or sites. In some Utah cities these are known as Site Based Ordinances.
Building Codes: Standards can be incorporated into building codes that address flood
proofing from all new and improved or repaired buildings.
Floodplain Ordinances: Communities that participate in the National Flood Insurance
Program NFIP are required to adopt the minimum floodplain management regulations,
as developed by FEMA. The regulations set minimum standards for subdivision
regulations and building codes. Communities may adopt more stringent standards than
those set forth by FEMA.
Storm Water Management: Development outside of a floodplain can contribute
significantly to flooding by covering impervious surfaces, which increase storm water
runoff. Storm water management is usually addressed in subdivision regulations.
Developers are typically required to build retention or detention basins to minimize any
increase in runoff caused by new or expanded impervious surfaces, or new drainage
systems. Larger cities and counties within Utah enforce an ordinance prohibiting storm
water from leaving a site at a rate higher than it did before the development.
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
160
Drainage System Maintenance: Ongoing maintenance of channel and detention basins is
necessary if these facilities are to function effectively and efficiently over time. A
maintenance program should include regulations that prevent dumping in or altering
watercourses or storage basins; regarding and filling should also be regulated.
D. Property Protection
Relocation: Moving structures out of the floodplain are the surest and safest way to
protect against damage. Relocation is expensive, so this approach will probably not be
used except in extreme circumstances.
Acquisition: Acquisition by governmental entity of land in a floodplain serves two main
purposes: it ensures that the problem structure is addressed; and it has the potential to
convert problem areas into community assets
Building Elevation: Elevating a building above the base flood elevation is the best on‐site
protection strategy. The building could be raised to allow water to run underneath it, or
fill could by brought in to elevate the site on which the building sits.
Insurance: Above and beyond standard homeowner’s insurance, there is other coverage
a homeowner can purchase to protect against flood hazard. Although this doesn’t
mitigate the problem it does allow the homeowner to shift the monetary loss/risk onto
another party. Two of the most common insurances offered against flood loss are:
• National Flood Insurance: when a community participates in the NFIP, any local
insurance agent can sell separate flood insurance policies under rules and rates
set by FEMA. Rates do not change after claims are paid because they are set on a
national basis.
• Basement Backup Insurance: National Flood Insurance offers an additional
deductible for seepage and sewer backup, provided there is a general condition
of flooding in the area that was the proximate cause of the basement getting
wet.
E. Public Information and Involvement
Outreach Programs: Outreach projects are proactive; giving the public information even
if they have not asked for it. Outreach projects should be designed to encourage people
to seek out more information and take steps to protect themselves and their properties.
Examples include:
• Mass mailing or newsletters to all residents
• Notices directed to high risk area residents
• Displays in public buildings
• Newspaper articles and special sections
• Radio and TV news releases and interviews
• A detailed property owner’s handbook tailored for local conditions
• Presentations at meetings and neighborhood groups
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
161
Real Estate Disclosure: Disclosure of information regarding flood or hazard prone
properties is important if potential buyers are to be able to mitigate damage. Federally
regulated lending institutions are required to advise applicant that a property is in the
floodplain. However, this requirement needs to be met only five days prior to closing,
and by that time, the applicant is typically committed to the purchase. This only includes
flood prone areas, at the exclusion of other hazards.
Map Information: Flood plain maps developed by FEMA outline the boundaries or the
flood hazard areas. These maps can be used by anyone interested in a property to
determine if it is in the floodplain. These maps are available from FEMA, the Utah
Division of Emergency Management, and at many city and county planning offices. In
addition, the Utah Geologic Survey creates and maintains maps illustrating geologic
hazards. These maps are available for sell at the Division of Natural Resources books
store.
F. Structural Projects
The intent behind structural projects for flood mitigation is to prevent floodwaters from
reaching properties. The shortcomings of almost all structural mitigation projects are
that:
• They can be very expensive
• They disturb the land, disrupt natural water flows, and destroy natural habitats.
• They are built to an anticipated flood event, and maybe exceeded by a greater‐
than‐expected flood.
• They can create a false sense of security
Reservoirs: Reservoirs control flooding by holding water behind dams or in storage
basins. After a flood peaks, water is released or pumped out slowly at a rate the river
downstream can handle. Reservoirs are expensive to build, occupy large tracts of land,
require maintenance, and if they fail often result in greater downstream flooding than
would occur during a natural flooding event.
Levees/Floodwalls: One of the best‐known structural flood control measure levees and
floodwalls are steel or concrete structures placed between the watercourse and the
land.
Diversions: A diversion is simply a new channel that sends floodwaters to a different
location, thereby reducing flooding along an existing watercourse. Diversions structures
can consist of surface channels, overflow weirs, or tunnels. During normal flows, the
water stays in the old channel but during flooding events floodwaters spill over into the
diversion channel.
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
162
Channel Modifications: Channel modifications include making a channel wider, deeper,
smoother, or straighter. Common channel modifications include:
• Dredging: Dredging is often cost‐prohibitive because the dredged material must be
disposed of somewhere else, and dredged streams usually fill back in with
sediment.
• Drainage Modifications: These include man‐made ditches and storm sewers that
help drain areas where the surface drainage system is inadequate or where
underground drainage ways may be safer or more attractive.
Storm Water Management: Mitigation techniques for managing storm water include
installing storm water systems, enlarging pipes, and street improvements in existing
storm water systems.
Earthquakes
Generic Mitigation is a list of generic earthquake mitigation strategies pertaining to
secondary threats often associated with earthquakes.
Generic Ground Shaking Mitigation
• Understand peak horizontal acceleration and recurrence interval
• Design appropriately
• Zoning ordinances and building codes
Generic Liquefaction Mitigation
• Move soil out
• Density soils in place
• Remove ground water
• Structural design
Generic Surface Fault Rupture Mitigation
• Avoidance
• Zoning ordinances
• Earthquake resistant building design codes
• Retrofitting of critical facilities and supporting equipment
• Retrofitting under‐designed buildings
• Annual warning of risk/info on how to protect property and lives
• Projects to seismically upgrade critical public facilities/utilities and shelters
• Gather hazard and risk data/information
• Protection of roads and bridges
• General infrastructure protection
• Development of improved mitigation techniques
• Education of local officials, developers, and citizens
A. Emergency Services
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
163
Emergency Operations Planning: Maintain an earthquake response plan to account for
secondary problems, such as fire and hazardous material spills.
Critical Facilities Protection: Protecting critical facilities are vital as the facilities play a
significant role in coordinating response and recovery following an earthquake. For this
reason, listed below are vital facilities and facilities with the potential of causing a
secondary disaster if destroyed.
• Facilities or locations vital to earthquake response efforts
• Emergency operations centers
• Police and fire stations
• Hospitals
• Highway garages
• Selected roads and bridges
• Evacuation routes
Facilities and locations, which if destroyed would create a secondary disaster:
• Facilities housing hazardous materials
• Wastewater treatment plants
• Schools
• Nursing homes
B. Natural Resource Protection
• Design of pipelines
• Land‐use planning
• Community master plans and zoning ordinances
C. Prevention
While earthquakes are not preventable proper planning, zoning, and building codes can
prevent much of the damage common with earthquakes. Planning, zoning, and building
codes should address minimums setbacks, critical facility locations, steep slopes, areas
with liquefiable soils, and insure high factor of safety ratings for critical facilities.
Community master plans and zoning ordinances define hazard areas and require
developers to show that any existing hazards have been investigated and new
construction will not be exposed to unacceptable risk.
D. Property Protection
Nonstructural Mitigation: Nonstructural mitigation consist of mitigation measures that
do not affect the overall look or purpose of the building yet prevent damage to non‐
structural aspects and lessen the loss of life. In addition, buildings with non‐structural
mitigation are frequently usable after an event.
Grand County Pre‐Disaster Hazard Mitigation Plan 2018
164
• Tie downs
• Flexible utility connections
• Mylar film on windows to prevent the glass from shattering
• Added bracing.
Retrofitting: consists of upgrading the seismic safety of a building through structural and
nonstructural mitigation techniques.
Insurance: Above and beyond standard homeowner’s insurance, there is other coverage
a homeowner can purchase to protect against earthquake hazard, something not
covered under most homeowner’s insurance plans. Although this doesn’t mitigate the
problem it does allow the homeowner to shift the monetary loss/risk onto another
party.
E. Public Information and Involvement
Public information and involvement for earthquakes is like the mitigation strategies
outlined in the flood and riverine section mentioned above.
Real Estate Disclosure: Disclosure of information regarding earthquakes and hazard
prone properties are important if potential buyers can mitigate damage. Unlike
floodplains there are no federal laws, which require disclosure of earthquakes.
F. Structural Protection
Mitigation measures can be any type of activity that reduces the likelihood or modifies
what is at risk from the hazard. Earthquake mitigation can be accomplished through
building codes that ensure safe and adequate construction including earthquake
resistant designs and construction. Older building should be retrofitted to comply with
the codes.

B. Natural Resource Protection
a. Soil awareness
C. Prevention
• Landscaping with vegetation that does not concentrate or draw substantial
amounts of water from the soil near foundations
• Insulating floors or walls near heating or cooling units to prevent evaporation
that could cause local changes in soil moisture
• Avoid areas underlain by limestone and dolomite to prevent ground water
contamination and foundation problems in karst terrain
• Use soil tests to find gypsum; do not plant high level of water plants near the
house
• Reduce piping damage by limiting construction that disturbs natural drainage
• Peat deposits should be removed or avoided at construction sites
• Avoid abandoned mine areas
• Sands and calcareous loamy soils are highly erodible
