9. SAFETY + HAZARDS
172 // YOUNTVILLE GENERAL PLAN
9.1 PURPOSE OF THE CHAPTER
Yountville is vulnerable to a range of public safety
threats including both natural and human-made
hazards. Earthquakes, flooding, fire, and extreme
heat events pose serious and real threats to the Town.
Planning is critical to identify potential hazards and
provide policies and regulatory actions to reduce
the community’s risk of death, illness, injury, property damage, and economic and social disruption.
This chapter presents a framework for governing future
decisions about how the Town will provide a safe
community and protect the community from natural
and man-made hazards. The chapter addresses the
requirements of the State-mandated safety element
and partially addresses the requirements of the land
use element of the general plan.
The Safety and Hazards chapter includes the following
sections.
9.2 Geologic and Seismic Hazards. Describes
environmental and man-made hazards including
earthquakes and soil stability.
9.3 Flooding Hazards. Describes flood hazards and
flood control measures to protect the community form
flooding.
9.4 Fire Hazards. Discusses fire risks, fire hazard
zones, and fire protection measures and service.
9.5 Climate Change Adaptation and Resilience.
Describes the impacts of a warming climate on
Yountville, including increased risk of extreme heat
events, more frequent and intense storms, sea level
rise, and wildfire.
9.6 Public Safety. Provides an overview of crime in
Yountville and police protection services.
9.7 Goals, Policies, and Programs. Identifies goals,
policies and programs minimize hazards and risks to
life and property.

9.2 GEOLOGIC AND SEISMIC HAZARDS
Yountville is located in the seismically active San
Francisco Bay region, an area with a long history
of tectonic movements. The region sits on the
boundary between two of the Earth’s major tectonic
plates—the Pacific and North American Plates—
which move inexorably past each other at a rate of
about two inches per year. Much of this motion is
accommodated from time to time by sudden slips on
faults, producing an earthquake. Although the San
Andreas fault is the main origin of slip, other faults
splay out from the plate boundary throughout most of
California.
The San Andreas fault, located about 32 miles
southwest of Yountville, was the source of the
magnitude 7.9 earthquake in 1906. The most recent
large earthquake on the San Andreas fault was the
magnitude 6.9 Loma Prieta earthquake in 1989. The
Loma Prieta earthquake caused intense seismic activity
throughout the Bay Area, collapsing a double-decked
freeway in West Oakland and destroying buildings in
San Francisco’s fill-based Marina District.
Active and potentially active faults in the Yountville
area include the West Napa Fault, which traverses
the planning area, and the Soda Creek Fault, which
is located approximately three miles to the northeast
of the Town limits, as shown in Figure SH-1. An
active fault is defined as one which has had surface
displacement within Holocene time, approximately
over the past 11,000 years. The southern section
of the West Napa fault is active while the northern
section is not active. Other inactive and unnamed
faults also traverse the Town limits.
The West Napa Fault has been identified to have
the potential to generate a 6.8 to 7.1 magnitude
earthquake. Earthquakes of this magnitude can kill
and injure many people and cause extensive damage
to buildings, roads, bridges, and utilities.
The Alquist-Priolo Earthquake Zoning Act (1972)
and the Seismic Hazards Mapping Act (1990) directs
the State Geologist to delineate regulatory zones
of required investigation, including Alquist-Priolo
earthquake fault zones and areas that are potentially
at high-risk for liquefaction and/or landslides. Cities and counties affected by the zones must regulate
certain development projects within them. The Acts
also require sellers of real property and their agents
within a mapped hazard zone to disclose at the time
of sale that the property lies within such a zone. There are no zones of required investigation within the Town.
However, Alquist-Priolo earthquake fault zones are
located in Napa County from the City of American
Canyon to the City of Napa, as shown in Figure SH-2.
These earthquake fault zones were identified after an
earthquake struck south Napa in 2014.
A magnitude 6.0 earthquake occurred in south Napa,
northwest of American Canyon, on the West Napa
fault in 2014. The earthquake injured nearly 200
people, mostly in Napa County, while touching off fires that destroyed at least six homes, buckled local roads, and damaged dozens of buildings in Napa and across
the region. The ground shaking was very strong along
the fault in in the Napa Valley, and many historical
masonry buildings and older residences in the City of
Napa were damaged. Buildings in Yountville were also
damaged.
The Town of Yountville was subject to a magnitude
5.2 earthquake on the West Napa fault in 2000.
More recently, a magnitude 4.1 earthquake occurred
in Yountville in May 2015. According to the US
Geological Survey, the epicenter was about nine miles
north of Napa and six miles northeast of Yountville, at a depth of 9.3 miles.
Significant earthquakes documented in the regional
vicinity are shown in Table SH-1.

Damage resulting from earthquakes is mainly from
shaking. The intensity of shaking that a structure will experience during an earthquake depends upon the
magnitude of the earthquake, the proximity to the
epicenter, and the type of ground materials beneath
the structure. Soft soils amplify the shaking, while hard bedrock does not.
All buildings located in Yountville are vulnerable
to earthquake damage, but depending upon
construction, some buildings are expected to perform
better than others. One and two-story wood-frame
buildings generally perform well, but they may shift
if not bolted to the foundation or partially collapse
if cripple walls (short walls between the foundation
and first floor that create a crawl space) are not
braced. Homes with rooms built over garages are also
vulnerable to collapse if walls are not reinforced or
braced. While current building codes address seismic
safety, they are designed to protect occupant lives
during an earthquake. Newly constructed buildings
can still be significantly damaged during a major
earthquake.

178 // YOUNTVILLE GENERAL PLAN
Unreinforced masonry buildings (including materials
such as brick, concrete and stone), pre-1940 woodframe houses, and pre-1973 concrete buildings are very likely to be damaged during earthquakes. In most
cases, these older buildings require retrofit, or they risk significant structural damage during an earthquake.
The Town of Yountville has six unreinforced masonry
buildings, three of which have undergone a partial
retrofit, including V Marketplace, Maison Fleurie, and
Gates Estates. In the 2014 earthquake in Yountville,
one unreinforced masonry building was red-tagged
and underwent a partial retrofit at that time. Another
historic building in the Town lost its brick chimney as a result of the 2014 earthquake.
Structures built in areas of water-saturated granular
sediment or fill material are susceptible to liquefaction.
The ground shaking from an earthquake transforms
the material from a solid state to a temporarily liquid state. Liquefaction is a serious hazard because
buildings in areas that experience liquefaction may
sink or suffer major structural damage. Most single
and multifamily homes under ten stories are unlikely
to have foundations stable enough to withstand
liquefaction even if they can withstand ground
shaking.
Liquefaction potential in the planning area includes
designation of “Very Low” to “Moderate” as shown
in Figure SH-3. Areas in Yountville designated with
moderate potential for liquefaction are generally
located on the Vintners Golf Club near California
Drive, as well as in the residential areas east of Yount Street and Washington Street. The remainder of the
planning area is designated “Very Low” and “Low”
potential for liquefaction.
Although an earthquake on the Hayward and Rodgers
Creek fault complex, which runs beneath San Pablo
Bay, could create a tsunami, there is believed to be
little potential for a tsunami to affect Yountville.
LANDSLIDE
Landslides are a potential hazard to structures, roads, and utilities on hillsides in Napa County. Landslides
can move slowly, as in hillside creep, or can move
quickly and disastrously, as is the case with debris
flows.
Almost every landslide has multiple causes. Landslides
can be initiated in slopes already on the verge of
movement by rainfall, erosion, earthquake, and
disturbance by human activities. Factors that indicate
the probable formation and relative risk of landslide
and slope instability include:
• Slope Steepness: Most landslides occur on
moderate to steep slopes.
• Slope Material: Loose, unconsolidated soils and
soft, weak rocks are more hazardous than are firm,
consolidated soils or hard bedrock.
• Water Content: Increased water content increases
landslide hazard by decreasing resistance to
sliding and adding weight to the materials on a
slope.
• Vegetation Coverage: Abundant vegetation with
deep roots increases slope stability.
• Proximity to Areas of Erosion or Man-Made Cuts:
Undercutting slopes may greatly increase landslide
potential.
• Earthquake Ground Motions: Strong ground
shaking may trigger landslides in marginally stable
slopes or loosen slope materials and thus increase
the risk of future landslides.
Hillsides in Napa County have a medium to high
susceptibility for landslides, while the valley has a low susceptibility. Figure SH-4 illustrates the landslide
potential in the vicinity of the planning area. Given
the relatively level slope throughout the Town, the
landslide potential is very low. The landslide potential increases in the foothills to the north and west of the planning area.

9.3 FLOODING HAZARDS
Yountville is subject to flooding problems along the
natural creeks and drainages that traverse the area,
particularly as a result of excessive overflow of the
Napa River and Hopper Creek. Land adjacent to the
Napa River is subject to flooding, with numerous
damaging floods recorded since 1862 when settlers
began keeping track of such events. Since that time,
21 serious floods have been recorded. The 1986 flood
is considered to be the worst flood experienced in
Napa County since 1900. A series of tropical Pacific
storms dumped between 12 and 28 inches of rain
throughout Napa Valley, causing the Napa River to
crest at 30 feet, five feet above flood stage in Napa.
The flood resulted in in three people dead, 27 injured, 5,000 evacuations, 250 homes destroyed, 2,500
residences damaged, and $100 million in damages.
Major floods since 1940 are shown in Figure SH-5.
The Town experiences localized flooding with heavy
rain events. Impacted areas typically include:
• Oak Circle adjacent to Vineyard Park
• Oak Circle at Heather Street
• Yount Mill Road at the cemetery
• Solano Avenue near Hinman Creek
• Finnell Road neighborhood
• Washington Street at California Street
• Yountville Bike Path
• Paths at Heather Street, behind mobile home
parks, and behind the Yountville Elementary
School.
Congress passed the National Flood Insurance Act of
1968 and the Flood Disaster Protection Act of 1973 to
address the increasing cost of flood-related disaster
relief. The intent of the National Flood Insurance
Program, which was established by the 1968 Act, is
to reduce the need for large, publicly-funded flood
control structures and disaster relief by restricting
development on floodplains.
The Federal Emergency Management Agency
(FEMA) administers the National Flood Insurance
Program to provide subsidized flood insurance to
communities that comply with FEMA regulations
and limit development on floodplains. FEMA issues
Flood Insurance Rate Maps (FIRM) for communities
participating in the flood insurance program. The
FIRM maps delineate flood hazard zones in the
community.
The FIRM maps play several critical roles. First, the
maps are used by local and county agencies to identify
and plan for local or area flood protection. Second,
the maps are used by the banking and insurance
industries to determine if flood insurance is mandated
for a specific property or area. Lands located within
the Special Flood Hazard Areas (areas subject to
1 percent chance of flooding in any given year)
require that flood protection insurance be secured
for federally-regulated or insured loans. Lastly, the
maps are used at the federal and State level to plan
for waterway projects that are administered by the
US Army Corps of Engineers. The most current FIRM
maps for Yountville were last updated and published
in 2008.
Improvements, construction, and developments within
Special Flood Hazard Areas are generally subject to
the following standards:
• All new construction and substantial improvements
of residential building must have the lowest floor
(including basement) elevated to or above the
base flood elevation (BFE).
• All new construction and substantial improvements
of non-residential buildings must either have the
lowest floor (including basement) elevated to or
above the BFE or dry-floodproofed to the BFE.
• Buildings can be elevated to or above the BFE
using fill, or they can be elevated on extended
foundation walls or other enclosure walls, on piles,
or on columns.

• Extended foundation or other enclosure walls
must be designed and constructed to withstand
hydrostatic pressure and be constructed with
flood-resistant materials and contain openings
that will permit the automatic entry and exit of
floodwaters. Any enclosed area below the BFE
can only be used for the parking of vehicles,
building access, or storage.
The Town’s Floodplain Management Regulations
are contained in Title 15, Division 2 of the Yountville Municipal Code. These regulations implement the
FEMA standards for construction and development
within Special Hazard Zones in Yountville.
Figure SH-6 shows the areas of Yountville that are
prone to flooding, as identified by FEMA. Areas in
the 100-year flood zone have a 1 percent chance of
flooding in any given year, while areas in the 500-year flood zone have a 0.2 percent chance of flooding.
Buildings with habitable living space or critical
building equipment below grade are likely to be
significantly damaged by flooding.
The 100-year floodplain is located mainly in the
eastern area of Town, as well as a small area near
Hinman Creek, west of Highway 29. These areas are
considered high flood hazards. Areas in the 500-
year floodplain include the Town’s mobile home
parks, which are protected by a flood wall that was
completed in 2006. These areas are considered low to
moderate flood hazards. The remaining areas outside
the 500-year flood zone are minimal flood hazards.
In addition to the flood wall project, the Town has
completed several projects to reduce flooding risks.
Most recently, the Town completed the Hopper Creek
flood control project in 2016. This project included
installation of three 36-inch pipes that drain to Beard ditch, three sedimentation basins, and curb, gutter,
and sidewalk improvements on Finnell Road. Ongoing
projects are planned to install drainage inlets on
Washington Street, underground the open ditch on
Monroe Street, and install full trash capture devices
at all drainage inlets. The Town also provides funding
annually to address localized flooding and drainage
issues in Town.
Despite the many improvements, Yountville will
experience local flooding in future years. During
the winter months, Napa County experiences
“atmospheric river” storms that can deliver over
one-inch of rain per hour over extended time frames,
causing localized and Napa River flooding. Scientists
warn that climate change could increase the frequency
and intensity of atmospheric river storms in California, mostly in the form of occasional years with more
extreme storms. These tendencies could produce
more frequent and severe flooding.
The Town works closely with other Napa County
jurisdictions to manage and reduce the impacts of
flooding from the Napa River. The Town is a member
of the Napa County Flood Control and Water
Conservation District, which is a separate government
entity responsible for developing and managing
domestic water supplies and managing flood and
storm water in Napa County. The District coordinates
projects intended to protect local communities from
inundation by maintaining and clearing tributary
channels and sponsoring capital improvements. This
includes serving as the local sponsor of the Napa
River/Napa Creek Flood Protection Project.
Yountville has completed several
projects to reduce flooding risks, and
works on an ongoing basis to address
flooding and drainage issues.

DAM INUNDATION
Yountville is subject to potential flooding resulting
from the failure of Rector Creek Dam. The earthen
embankment dam, built in 1946, stores about 4,600
acre-feet of water and the crest height is 164 feet.
Earthquakes centered close to a dam are typically the
most likely cause for failure. The area that would be
inundated in the event of a sudden failure of the dam
is shown in Figure SH-7. The California Department
of Water Resources considers downstream hazards of
the dam to be extremely high, with considerable loss
of life and major impacts to critical infrastructure or property should the dam fail when operating with a full reservoir.
Rector Creek Dam is owned and maintained by the
California Department of Veteran Affairs. According
to the Department of Water Resources, the dam is
certified and may safely impound water. It is also in
satisfactory condition, with no existing or potential
dam safety deficiencies.

9.4 FIRE HAZARDS
The California Department of Forestry and Fire
Protection (CAL FIRE) identifies fire hazard severity
zones based on the severity of the fire hazard
expected to prevail there. These areas are based on
factors such as fuel type (vegetation that is fire prone), slope, aspect, and fire weather. There are three zones, based on increasing fire hazard: moderate, high, and
very high.
Areas under State jurisdiction are referred to as State Responsibility Areas (SRAs). Within the vicinity of the Town, these SRAs are primarily found to the north
and west of the Town limits. As shown in Figure SH-8,
areas adjacent to the north of Town are categorized as
a moderate fire hazard severity zone, while areas to the west of Town are categorized as moderate, high, or
very high. The very high zone extends to the Sonoma
County line, which is approximately 4.65 miles to the
west of Town.
Areas under the jurisdiction of local entities are
referred to as Local Responsibility Areas. CAL
FIRE identifies very high fire zones within Local
Responsibility Areas. The majority of Town is not
categorized as a fire hazard severity zone. However,
a small area in the southwestern corner of the Town
limits is categorized as a very high fire hazard severity zone. This zone is in a remote, undeveloped area
within the Veterans Home property, which is owned
and maintained by the California Department of
Veterans Affairs.
Historically, fires in the Yountville area have occurred mainly to the east and west of the Town in the hillside areas. The devastating wildfires of October 2017
largely conformed to this historic pattern, with the
Nuns Fire located in the hills to the west of Town and
the Atlas Fire to the east of Town, as shown in Figure
SH-9.
The Atlas Fire started on October 8, 2017. By the
time it was fully contained on October 27th, the fire
had burned 51,624 acres in Napa and Solano counties
and destroyed 783 structures. There were six civilian
fatalities. CAL FIRE determined the fire started in two locations from a large tree limb and a tree that fell on PG&E power lines.
The Atlas Fire encompassed a north-south trending
ridge that is roughly bounded by Napa Valley to the
west, Highway 128 to the north, Capell Valley Road to
the northeast, Wooden Valley Road to the southeast,
and Highway 12 and Green Valley road to the South.
The closest the Atlas Fire got to Yountville was at
the Silverado Trail, about 1.5 miles to the east of the Town limits. The burn area ranged from about 200
feet above mean sea level west of Napa to Atlas Peak
at 2,663 feet and comprised grassland, chaparral,
and oak woodland. The area within the Atlas Fire
perimeter had an active fire history, with approximately 58 percent of the area having been previously burned
since 1980.
The Nuns Fire also started on October 8, 2017, and,
according to CAL FIRE, was caused by a broken top
of a tree coming in contact with a PG&E power line.
The Nuns Fire was part of series of fires that merged
in Napa and Sonoma counties. These fires burned
a total of 56,556 acres, destroyed 1,355 buildings,
and resulted in three civilian fatalities. The fire was fully contained on October 31, 2017. The fire area
was located on the western and eastern flanks of the
Mayacamas Mountains and extended into Sonoma
County’s Highway 12 Corridor and Bennet Valley. In
the Yountville vicinity, the fire reached Dry Creek Road, about one-half mile to the west of the Town limits.
The burn area ranged in elevation from about 200 feet
along Sonoma Creek to 2,730 feet at Hood Mountain.
Vegetation was largely comprised of oak woodland,
chaparral, mixed hardwood/conifer forest, grassland,
and vineyards. Approximately 27 percent of the area
had been previously burned since 1951.
Defensive positions and significant fire resources
deployed at Mt. Veeder Road and Dry Creek Road to
the west of Town and at the Silverado Trail to the east of Town spared Yountville from the most devastating

impacts of the fires. The Town was never under a
mandatory evacuation order, although the Veterans
Home opted to move their skilled nursing facility
residents on the second day of the fire. Heavy smoke
resulted in poor air quality in Town, and residents
with respiratory concerns were encouraged to leave
the area. Although the Town was initially hampered
by compromised internet and cell phone service, by
October 11th the Town was providing regular email
updates on fire conditions and available resources.
Information was also provided through the Town’s
emergency alert system, NIXLE, and the Town’s
social media outlets. The Town kept the Yountville
Community Center open daily and distributed
breathing masks to community members.
FIRE PROTECTION SERVICES
The Town of Yountville contracts for fire protection
services with the Napa County Fire Department
(County Fire). The Veterans Home has a separate
contract with County Fire. County Fire, in turn,
contracts with the California Department of Forestry
and Fire Protection (CAL FIRE). Countywide, CAL FIRE
provides administrative support and coordination
with five full-time paid stations and nine volunteer fire companies operating under a County Fire Plan, which
is approved by the Napa County Board of Supervisors.
The Napa County Fire Chief is responsible for the
direction and coordination of fire protection services
by these organizations on a countywide basis.
A three-way cost sharing arrangement between Napa
County, the Town, and the Veterans Home funds
operation of Fire Station 12 located at 7401 Solano
Avenue in Yountville, shown in Figure SH-8. County
Fire/CAL FIRE services in Yountville include staffing
the fire station and providing structure fire protection, wildland fire protection, emergency medical response,
technical rescue/extrication, hazardous materials,
water supply, dispatch, training, fire safety education, fire (arson) investigation, fire prevention, vegetation management, and Fire Marshal (code enforcement)
services. Additionally, County Fire offers domestic
preparedness planning and response.
Yountville is assured a minimum level of staffing of four persons 24 hours a day, seven days per week. Service
levels are evaluated on a regular basis by County Fire.
The Town’s municipal fire hydrant system has a fire
hydrant strategically placed within 1,000 feet of all
locations throughout the Town limits. The hydrant
capacity/rating is sufficient at more than 1,000 gallons per minute. There are seven water tenders in the
Napa County Fire Department that can be utilized in
addition to or in place of the hydrant system.
County Fire/CAL FIRE’s average response time is three
minutes. The goal is to be at the scene within four
minutes, 90 percent of the time. The response time
includes the 911 call, dispatching, turnout time, and
response time to the scene.
Through a series of automatic aid and contractual
agreements with the other five fire agencies in Napa
County, County Fire augments its level of service by
providing closest resource response to those areas
of the County that are immediately adjacent to
these jurisdictions. These agreements also include
a reciprocal response of County Fire resources when
requested.
The Yountville Fire Station 12 responded to 1,716 calls during 2016, of which 17 percent were incidents within
the Town limits. A large majority of these calls were for medical aid response.
The Napa County Fire Marshal’s Office is a division
within the Napa County Fire Department. Personnel
assigned to this office are CAL FIRE employees
under contract by the County of Napa to provide
fire prevention and code enforcement duties in the
unincorporated areas of Napa County and the Town
of Yountville. The Fire Marshal provides plan review
and inspection for use permits, new construction,
and special events. The Fire Marshal’s Office enforces
the California Fire Code and locally adopted
amendments, including residential and commercial
development standards, address signage and
sprinkler requirements, defensible space requirements
for structures and roadways, and road and street
standards.

9.5 CLIMATE CHANGE ADAPTATION AND RESILIENCE
The Earth’s climate is warming, mostly due to human
activities such as changes in land cover and emissions
of certain pollutants. Greenhouse gases are the major
human-induced drivers of climate change. These
gases warm the Earth’s surface by trapping heat in the
atmosphere.
The evidence that the climate is warming is
unequivocal. Global surface temperatures have
increased 0.9 °C (1.6 °F) relative to the 1951-1980
average temperatures. Seventeen of the 18 warmest
years in the 136-year record have occurred since
2001, and the year 2016 ranks as the warmest on
record (NASA/GISS, 2018). Consistent with global
observations, annual average air temperatures
have increased by about 1.8 °F in California, with
temperatures rising at a faster rate beginning in the
1980s.
As temperatures continue to rise, California faces
serious climate impacts, including:
• More intense and frequent heat waves
• More intense and frequent drought
• More severe and frequent wildfires
• More severe storms and extreme weather events
• Greater riverine flows
• Shrinking snowpack and less overall precipitation
• Accelerating sea level rise
• Ocean acidification, hypoxia, and warming
The Cal-Adapt.org web portal provides resources to
help communities understand how climate change
will raise temperatures and exacerbate extreme heat
events, drought, wildfire, and coastal flooding in their area. The Cal-Adapt tool shows projections for two
possible climate futures, one in which greenhouse gas
emissions peak around 2040 and then decline (RCP
4.5) and another in which emissions continue to rise
strongly through 2050 and plateau around 2100 (RCP
8.5). Both futures are considered possible depending
on how successful the world is at reducing emissions
and atmospheric carbon dioxide.
Emissions scenarios used in the General
Plan are the same as those used by the
Intergovernmental Panel on Climate
Change’s Fifth Assessment Report and
are called Representative Concentration
Pathways, or RCPs. There are four RCPs:
2.6, 4.5, 6.0, and 8.5. Each represents a
set of possible underlying socioeconomic
conditions, policy options, and technological
considerations, spanning from a low-end
scenario that requires significant emissions
reductions resulting in zero global emissions
by 2080 (RCP 2.6) to a high-end, “businessas-usual,” fossil fuel-intensive emissions scenario (RCP 8.5). The low-end scenario
is most closely aligned with California’s
ambitious greenhouse gas reduction targets
and the aspirational goals of the United
Nations Framework Convention on Climate
Change 2015 Paris Agreement. Thus far,
global emissions continue to follow the
business-as-usual trajectory.

AVERAGE MAXIMUM
TEMPERATURES
Overall temperatures are projected to rise substantially throughout this century. The historical (1990-2005)
annual maximum mean temperature for Yountville is
72.0oF. Under the low emissions (RCP 4.5) scenario, the maximum mean temperature in Yountville is expected
to rise about 3°F by 2050 and 5°F by 2100 (see Table
SH-2). Under the high emissions (RCP 8.5) scenario,
the maximum mean temperature is projected to rise
9°F to about 81°F by 2100.
Warmer temperatures will increase the demand for air
conditioning and cooling systems. A common proxy
used to understand the demand for energy needed
to cool buildings is Cooling Degree Days (CDD).
A Cooling Degree Day is defined as the number
of degrees by which a daily average temperature
exceeds a reference temperature, in this case
65°F, which loosely represents the average daily
temperature above which space cooling is needed.
According to the Cal-Adapt modeling tool, the
average number of Cooling Degree Days will increase
from an historical average of 609 CDD in Yountville
to 991 CDD by 2050 and will double to 1,271 CDD
by 2100 under the RCP 4.5 scenario. Under the high
emissions scenario, that average more than triples to
2,117 CDD.
AVERAGE MINIMUM TEMPERATURES
The historical annual minimum mean temperature for
Yountville is 45.9°F. Under the low emissions scenario
(RCP 4.5), the minimum mean temperature is expected
to rise about 2°F by 2050 and 3°F by 2100. Under the
high emissions scenario (RCP 8.5), the maximum mean
temperature is projected to rise 7°F by the end of the
century.
Warmer temperatures should reduce the demand
for energy for space heating, and the Cal-Adapt tool
shows a decrease in the projected number of Heating
Degree Days (HDD). A Heating Degree Day is defined
as the number of degrees by which a daily average
temperature is below the reference temperature of
65°F. The historical annual number of Heating Degree
Days in Yountville is 2,821 HDD. That number is
projected to decrease about 14 percent by 2050 and
27 percent by 2100 under the low emissions scenario
(RCP 4.5). Under the high emissions scenario (RCP 8.5), the number of Heating Degree Days declines by 50
percent by the end of the century.
Overall, the models project an increase of about 380
Cooling Degree Days and a decrease of about 400
Heating Degree Days by mid-century under a low
emissions scenario. Considering that most heating
systems use natural gas and most cooling systems

Yountville, this may be somewhat positive news for
future mitigation of greenhouse gas emissions.
EXTREME HEAT DAYS
As the climate changes, some of the more serious
threats to public health will stem from more frequent
and intense extreme heat days and longer heat waves.
Extreme heat events are likely to increase the risk of
mortality and morbidity due to heat-related illness,
such as heat stroke and dehydration, and exacerbation
of existing chronic health conditions.
An extreme heat day is defined as a day in April
through October where the maximum temperature
exceeds the 98th historical percentile of maximum
temperatures based on daily temperature data
between 1961-1990. In Yountville, the extreme heat
threshold is 100.2°F.
Cal-Adapt projects a significant increase in the number of extreme heat days for Yountville, as detailed in
Table SH-2. Between 1990-2005, there was an average
of 2.7 days above 100.2°F. That average is projected
to increase to 11 days by 2050 under the low emissions
scenario (RCP 4.5). By the end of the century, the
average number of extreme heat days is expected to
increase to 13 days and could be as many as 33 days
under the high emissions scenario (RCP 8.5).
Those most at risk and vulnerable to heat-related
illness are the elderly, infants, the socially or
economically disadvantaged, those who work
outdoors, and individuals with chronic conditions
such as heart and lung disease, diabetes, and mental
illnesses. In Yountville, where there is already a large senior population that is expected to grow by nearly
60% by 2040, heat-related illness is of significant
concern. Currently, nearly half of Yountville’s
population are 65 and older and 25 percent are over
80 years old. There are also many individuals with
disabilities and chronic illnesses at the Veterans Home.
RAINFALL
The historical annual mean rainfall for Yountville is
37.5 inches. Under the low emissions scenario (RCP
4.5), annual mean rainfall is expected to rise about 3
inches by 2050 and 4 inches by 2090, as shown in Table
SH-3. Under the high emissions scenario (RCP 8.5),
annual mean precipitation is projected to increase
about 9 inches by 2090. As discussed in the section
on flooding, climate scientists warn that climate
change could increase the frequency and intensity
of atmospheric river storms in northern California,
potentially producing more frequent and severe
flooding. While the expected increase in rainfall may
exacerbate local flooding, the projections also mean
that local water resources may not be negatively
impacted by climate change.

SEA LEVEL RISE
The San Francisco Bay is vulnerable to a range of
natural hazards, including storms, extreme high
tides, and rising sea levels resulting from global
climate change. Flooding already poses a threat to
communities along the Bay and there is compelling
evidence that these risks will increase in the future.
As temperatures rise globally, sea levels are rising
mainly because ocean water expands as it warms,
and water from the melting of major stores of land ice
and glaciers flow into the ocean. In the past century,
average global sea level has increased by 7 to 8
inches. Sea level at the San Francisco tide gauge has
risen by about 7 inches since 1900.
Rising seas put new areas at risk of flooding and
increase the likelihood and intensity of floods in
areas that are already at risk. The State’s Sea Level
Rise Guidance Document projects a “likely” (66%
probability) increase in sea level at the San Francisco tide gauge of 10 inches by 2040 and 13 inches by 2050.
By the end of the century, sea levels are likely to rise by 2.4 feet under a low emissions scenario (RCP 2.6)
and 3.4 feet under a high emissions scenario (RCP 8.5).
Flooding will be more severe when combined with
storm events.
Although Yountville is located far enough away
from the coastline to avoid direct impacts of sea
level rise, flooding could impact travel to and from
Yountville. State Route 37, for example, passes
through the marshes of North San Francisco Bay,
providing commuters, tourists, and trucks with access
to Napa County from Interstate 80 and US Highway
101. Models show that stretches of the highway are
inundated at 1.6 feet of sea level rise. Thus, sea level rise could impact Yountville’s tourist economy, as well as the transport of goods and services to the Town.
WILDFIRE
Wildfire is a serious hazard in California. Several
studies have indicated that the risk of wildfire will
increase with climate change. According to Cal-Adapt,
the historical annual average area burned by wildfire in Napa County is 3,343 acres. As shown in Table SH-4,
that average is expected to increase under both low
and high emissions scenarios throughout the century.
By 2090, the models predict an increase in burned
areas of about 26 to 28 percent.
Prolonged and more severe drought may exacerbate
conditions for wildfires to ignite and spread. An
increase in wildfire intensity and extent will increase public safety risks, property damage, fire suppression
and emergency response costs, watershed and water
quality impacts, vegetation conversions, and habitat
fragmentation.

ADAPTIVE CAPACITY
Adaptive capacity is the current ability of a community to address the potential impacts of climate change.
Yountville has existing policies, plans, programs,
resources, and institutions that are already in place
to adapt to climate change and reduce potential
impacts. Resources to address flooding and storm
events are described in Section 9.3 of the Safety +
Hazards Chapter, and resources for fire prevention
and protection are covered in Section 9.4. In addition, the Town has an emergency operations plan which
can be activated for a variety of emergency situations, including flooding, wildfire, and extreme heat events.
The Town’s Community Center operates as a cooling
center during extreme heat days and heat waves.
The Town’s local hazard mitigation plan, described in
Section 9.6 of this chapter, was adopted in 20132020.
The next update of the plan will include an analysis of climate change impacts and adaptation and resiliency
strategies.

9.6 PUBLIC SAFETY
The Town contracts with the Napa County Sheriff’s
Department to provide law enforcement and police
protection services throughout Yountville. County
Sheriff is responsible for enforcing all State statutes, local codes, and ordinances, including traffic
enforcement within the Town limits. The current
contract obligates the County Sheriff to provide a
minimum of 160 hours of patrol services in Yountville
weekly and provides for a full spectrum of municipal
law enforcement services, including:
• Personnel management (recruitment, hiring,
training, etc.)
• Vehicles and equipment, including maintenance
• Dispatch services
• Records management
• Crime scene and lab processing
• Property/evidence management and storage
• Investigative services (major crimes and major
traffic collisions)
• Supplemental patrol services
• Canine services
• Animal control services
• Hazardous device mitigation
• SWAT and hostage negotiation
• Disaster response management and training
• Special event services
• Participation in DARE program
• Attendance at Town Council, board and
commission, and other Town meetings as
requested
Yountville contracts with the Napa County Sheriff ’s Department to provide law enforcement and police protection services.
The Napa County Sheriff’s Office is located near the
Napa County Airport at 1535 Airport Blvd. There are
several substations in locations throughout the county.
The Town of Yountville Police Station is located at
1950 Mulberry Street and is shown in Figure LU-4. The
Town is responsible for providing and maintaining the
substation.
The Sheriff’s Department has approximately 135
employees. There are three dedicated deputies
assigned to the Town as well as one sergeant who
acts as the Chief of Police for the Town. The sergeant
attends Town Council meetings, and supervises any
deputies working in the Town. County Sheriff evaluates
and makes recommendations regarding Yountville’s
service levels at least once per quarter.
As shown in Table SH-5, the majority of crimes
committed in Yountville consist of non-violent property crimes, primarily theft of personal property without
the use of force. The table shows crime statistics
through 2016, the latest year for which data is
available. An active shooter incident in March of 2018
at the Veterans Home resulted in the deaths of three
hostages. The gunman, a veteran suffering from posttraumatic stress disorder who was formerly housed at a residential program within the Veterans Home, also
died during the standoff with police.

EMERGENCY OPERATIONS AND
HAZARD MITIGATION
The Town works with the Napa County Office of
Emergency Services to develop and implement
emergency and hazard mitigation plans.
The Napa County Multi-Jurisdictional Hazard Mitigation
Plan for the Town of Yountville planning area (the
Town’s “Local Hazard Mitigation Plan” or “LHMP")
was developed in accordance with the Disaster
Mitigation Act of 2000 and followed FEMA Local
Hazard Mitigation Plan guidance. The LHMP was
prepared in cooperation with the Town of Yountville,
the Cities of American Canyon, St. Helena, and
Calistoga, the Napa County Flood Control and Water
Conservation District, Napa Valley College, and
the Napa County Office of Education. The California
Office of Emergency Services (Cal OES) and FEMA Region
IX officials have reviewed and approved the MJHMP.
Major threats addressed in the plan include flooding,
earthquake, and wildland urban interface fires. In
2013, the County of Napa adopted the Napa County
Operational Area Hazard Mitigation Plan, The Hazard
Mitigation PlanLHMP addresses a wide variety of
disasters that could affect Napa County and provides measures for reducing or mitigating these threats. The plan is prepared pursuant to the requirements of the Disaster Mitigation Act of 2000 and is updated periodically.
Major threats addressed in the plan include flooding,
earthquake, and wildland urban interface fires climate change, drought, earthquake, flood, wildfire, and dam failure. The Hazard Mitigation Plan analyzes the risk of each
197
of these hazards and includes a detailed
assessment of how critical facilities (public
buildings, hospitals, day care centers, etc.)
would be affected by fire, earthquake, and
other disasters.
The Town maintains an Emergency
Operations Center at Town Hall. The
Center facilitates a coordinated response
during a major emergency or disaster.
The Town’s Emergency Operations Plan
guides the planned response to emergency
situations as well as coordination with other
governmental agencies when required.
The Town prepares evacuation routes in
cooperation with Napa County OES which
are intended for use by first responders.
Actual evacuation routes may need to be
modified in the field during emergencies.
Evacuation policies and procedures are
addressed in Section3 of the Town’s All
Hazards Emergency Operations Plan.
