RE: FINANCIAL REPORT FOR THE PERIOD ENDING SEPTEMBER 30, 2023 BACKGROUND:

This report provides a detailed financial summary by department for the fiscal year 2023-2024. It offers a comprehensive overview of the budget allocations, expenditures, and accomplishments of each department within the city government. The report aims to transparently communicate the financial status and performance of various departments, highlighting their contributions to the city's overall development and well-being.

DISCUSSION:

In the initial three months, the city's General Fund revenues stand at 7% of the budget, falling short of the 25% target, which is a common trend in the first quarter of the fiscal year. This lower percentage is due to the majority of tax revenue being received and recognized in the previous fiscal year, specifically in July and August. However, it is expected that revenues will rise in the next quarter, gradually aligning more closely with the budgeted goals. The Enterprise fund revenue exceeds the budget target, standing at 26%.

The city's General Fund expense was at 20% of the budget, just below the 25% target. Savings were in salaries and benefits due to unfilled positions and deferred one-time purchases. This situation will improve in the next quarter as vacant positions get filled, salary expenditures are expected to increase, aligning with the budget. Enterprise Fund expenditures are slightly below target at 22%, indicating effective financial management within the organization.

Budget to Actual by Department
In the first quarter, most departments are under budget except for finance and general administration, which are slightly over due to one-time annual payments made at the beginning of the year. Despite this, overall operating costs are under budget by 7% in this department. 25%

Executive
Summary
3 This Executive Summary recaps the purpose of the Calaveras County Evacuation and Access Needs Assessment and Preparedness Plan (CCEANAPP) and provides an overview of the planned steps the County of Calaveras will take to build resiliency in the transportation systems from the impacts of wildfires, extreme weather, and other events. Additionally, the methods used to develop the CCEANAPP, including the evaluation of existing conditions, Hazard Risk and Vulnerability Assessment, and Public Outreach/Advisory Committee Meetings are discussed.
4 Purpose of This Plan
The Evacuation and Access Needs Assessment and Preparedness Plan (Plan) is a call to action for Calaveras County, including the City of Angels. Calaveras County’s transportation system faces a harsh reality from the Valley to the Sierra Nevada. The impacts of wildfires, extreme weather, and other events threaten the health and efficiency of the existing roadway network.

This plan aims to build resiliency in our transportation system by assessing the network’s demands, capacity, and deficiencies or needs in responding, recovering, and adapting to catastrophic events. This Plan will utilize data and findings from the recently completed Caltrans District 10 Vulnerability Assessment and the county’s Multi-jurisdictional Hazard Mitigation Plan.

Our region is best known for its wide range of recreational opportunities and thriving tourism industry. From the sea-level rolling hills sprinkled with century-old oaks to the Sierra crest exceeding 8,000 feet, more than 45,828 people have settled and call Calaveras County home. Our communities take pride in the numerous attractions including Calaveras Big Trees State Park, New Melones Reservoir, our Gold Rush History, and more than 15 wineries. Calaveras is home to the City of Angels (Angels Camp) and other census-designated communities including Arnold, Avery, Burson, Copperopolis, Dorrington, Douglas Flat, Hathaway Pines, Mokelumne Hill, Mountain Ranch, Murphy’s, Railroad Flat, Tamarack, Vallecito, Valley Springs, Wallace, West Point and the California Valley Miwok Tribe.

Our Home
Too Close to Home
Despite the natural beauty of the County, Calaveras faces a growing threat with its varying topography, and mix of urban and rural areas, which is subject to a wide variety of negative impacts from various hazards and threats. Calaveras County has a wide range of challenging topography, fuels, and weather, influencing the nature of wildland fires within the boundary. With the ongoing periods of drought, the aftermath of the bark beetle infestation, and overall forest health, the fire season has transformed into a year-round event. Since 1988, several state and federal disaster declarations for wildfires have been made. In addition, eight local states of emergency have been adopted by the Calaveras County Board of Supervisors for 2017, 2019, 2021, 2022 and 2023 winter storms, Butte Fire, removal of hazardous trees caused by the Butte Fire, and Tree Mortality.

The County is served by four main state routes that serve as our main arterials and travel corridors. Few other roadways in the county serve as community connectors, and the ones that do are narrow two-lane local roads with little to no shoulders. Due to the terrain, during extreme weather conditions and natural disasters, particularly in higher elevations, roadways are vulnerable to failure. Most of our highest-risk and vulnerable communities rely on one access route, and if that route fails, could result in devastating impacts.

Executive Summary 5
Protecting Our Home
As a result of past natural disasters and inevitable future catastrophes, we have been given a challenging opportunity, to better prepare by mitigating, repairing, and planning. By focusing on and assessing the transportation network’s demands, capacity, and deficiencies in responding, recovering, and adapting to catastrophic events, a more resilient and robust roadway network will be available to the community. 754 pins were dropped by community members during the Priority Corridors Evaluation 226 community members provided feedback to the online community surveys 7 community members participated in the Climate Debrief interviews Community Engagement

What We Have Done
An Existing Conditions Report
The foundation of this plan was developed by
identifying opportunities and constraints,
incorporating prior planning and development
efforts, and learning from past extreme weather
events. Calaveras County Office of Emergency
Services Hazard Mitigation Plan, Caltrans Climate
Change Vulnerability Assessment for District 10,
and Amador County Transportation Commissions'
Extreme Weather Preparedness Plan were studied
to understand and recognize existing plans and
mitigation processes and climate change
projections expected to impact the transportation
network. The Existing Conditions Report
characterized roadway assets including roadway
classification, use, ownership, current capacity, and
future traffic projections. Existing and planned
land use developments and population
characteristics including disadvantaged
community status were identified.

The Calaveras County Evacuation and Access Needs Assessment and Preparedness Plan was developed through extensive planning efforts between various agencies and stakeholders who shared the goal of further preparing and adapting our communities to become more resilient.

Recognizing the urgent transportation challenges caused by severe weather conditions like wildfire and flooding evacuations, motivated the community to make a change and prepare for future disasters.

The plan leveraged the combined efforts of more than 130 community members, stakeholders, subject matter experts, and emergency response personnel. The Plan was built around four key components: Public Outreach, Existing Conditions Assessment, Analysis of Hazard Risk and Vulnerability, and Priority Corridor Identification.

Project Advisory Committee (PAC)
To help guide the development of the project, a
Project Advisory Committee (PAC) was created
with a diverse group of agencies and external
stakeholders including representatives from the
City of Angels Camp, Calaveras County, Caltrans,
local fire districts, law enforcement, and others. Assessed Existing Conditions

A Climate Debrief Interview Summary
Public officials, first responders, and other key
stakeholders from Calaveras County were
interviewed to identify evacuation and access
needs, lessons learned, and to gather strategies
to address future events in the County. Events
discussed include the 2015 Butte Fire, and the
devastating 2017, 2019, and 2021 winter storms.

Interviews are summarized in the Climate
Debrief Interview Summary. (See Appendix D)
Community Workshops
The project was centered around community
workshops, which included both online and
in-person formats. The project was
introduced to community members at
Workshop #1, during the Existing Conditions
phase and the community was asked to
provide information about local experiences
during extreme weather and locations for
further review as risk, opportunity, and
constraint sites. Workshop #2 took place
during the Analysis Phase and was intended
to present and receive feedback on the
concept menu and gather information on
community priority locations to help inform
the selection of the Priority Sites for
Conceptual Alternatives. During Workshop
#3, a two-week review period was utilized to
assess the Draft plan.

Online Engagement
As a supplement to the community
workshops, an informative Project Website,
Interactive Mapping Tools, and Project
Surveys were developed and made available
to the public. The website was a host for
project information, event summaries,
recordings, and a place where comments
from community members could be made. In
addition to the in-person workshops,
MetroQuest Surveys were sent out to the
community to obtain specific information,
like identifying roads with high fire risk,
overgrown vegetation, narrow shoulders,
congestion, etc. Notifications and Surveys
were sent to all PAC members and
stakeholders for further distribution to their
associated agencies and community groups
throughout the county.

A Hazard Risk and Vulnerability
Assessment
The Hazard Risk and Vulnerability
Assessment includes an analysis of roadway
and transportation elements vulnerable in a
natural disaster scenario. Different areas of
the County were analyzed based on risk
factors including, flooding/dam failure,
wildfire, avalanche, extreme weather,
geologic hazards, and drought. (See
Appendix F)
8 Priority Corridors and Key Considerations
for Future Evacuation Plans
To fully understand the complexity and
uniqueness of the transportation network, a
data-based platform was used to analyze
traffic conditions and residents were asked to
help identify priority routes and
communications during an evacuation event.

The results from these exercises are
summarized in Chapter 5, Priority Corridors
and Key Consideration for Future
Evacuation Plans.

Figure E.4 Plan Processes Graphic (enlarged)
What We’ve Learned
The Calaveras County Evacuation and Access Needs Assessment and Preparedness Plan focuses on how climate catastrophes and extreme weather event disasters affect the transportation network throughout Calaveras County. During evacuation events, essential elements like road conditions, roadway access, roadway capacity, and communication become exceptionally challenging.

Public Officials, first responders, and other stakeholders in the region who could provide input on recent extreme climate events were interviewed in the Climate Debrief. Key challenges and constraints for evacuation and access, strategies employed, and opportunities for planning and response moving forward were discussed. Four unique fire events of various scales were identified and examined. In addition to wildfires, several other types of hazardous events were identified by interview participants, including the 2017 winter storm which resulted in a road closure of a section of State Route 26 for more than 30 days.

The Hazard Risk and Vulnerability
Assessment evaluated the susceptibility of
Calaveras County’s communities and
transportation assets to natural hazards. A
Community Assessment focused on the
impacts on people by examining vulnerability,
and a Transportation Asset Assessment
focused on the impacts on the County’s overall
transportation network by examining the risk
to roads and bridges that were built. Both
assessments used a relative framework that
assigned scores compared to the rest of
Calaveras County resulting in final scores that
categorize communities based on their risk
and vulnerability compared to all other
communities in the County. Mountain Ranch,
Dorrington, Douglas Flat, West Point,
Wilseyville, Sheep Ranch, Vallecito, and
Railroad Flat were identified as communities
with the highest vulnerability. The Highest-risk
roadways included State Route 4 in Murphys,
State Route 4 in Vallecito, State Route 4 in
Arnold, and State Route 49 in San Andreas.

Additionally, several bridges were identified as
high risk, including State Route 49 and
Vallecito Road at Angels Creek,
Vulnerability
Developed Hazard Planning Zones
Hazard Planning Zones were developed to
group areas within the County based on
location, demographics, roadway access,
and past events. The zones were developed
with an evacuation event in mind and are
shown by zones being generally located
along primary corridors. Each zone faces its
own unique challenges, from traffic
bottlenecks to limited cell phone service
and limited roadway access. Critical
facilities, potential evacuation centers, lane
miles, traffic volumes and population
demographics are summarized in Chapter
One, Hazard Planning Zones.

Monge Ranch Road at Coyote Creek,
Railroad Flat Road at Esperanza Creek,
Sheep Ranch Road at McKinney Creek,
Schaad Road at Middle Fork Mokelumne
River, Sheep Ranch Rd at O’Neil Creek,
Sheep Ranch Rd at San Antonio Creek and
Unnamed Road at Blue Creek.

Executive Summary 10
What We’ve Learned
In early 2023, Calaveras residents’ priority
routes and communication during evacuation
events were identified in the Priority Corridors
and Key Considerations for Future
Evacuation Plans. Community-wide surveys
(MetroQuest) and GPS-based data platforms
(Replica) were utilized to analyze traffic
conditions during evacuation incidents.

Westbound State Route 4, Westbound State
Route 12, Northbound State Route 49, and
southwest-bound State Route 26 were
identified as priority routes used by residents
leaving the county. Likewise, most Calaveras
County residents live in communities located
on state routes, making these Caltrans state
routes priority evacuation routes. In addition to
State Routes, local, county-maintained roads
were also identified and included O’Byrnes
Ferry Road, Parrotts Ferry Road, Milton Road,
Murphys Grade Road, and Railroad Flat Road.

Examining existing conditions, recognizing
vulnerable communities, and identifying atrisk, high-priority roadways and bridges were foundational components in developing this
plan. With the results from these assessments,
we were able to concentrate on projects that
have the greatest benefit for our region’s
transportation network. In Chapter 6,
Achieving a Resilient Network, improvement
projects varying from major (shoulder
widening, defensible space clearing, hazard
tree removal) to minor annual maintenance
programs (defensible space clearing, roadside
ditch clearing,
Identified Priority Corridors
Working Towards a More Resilient
Roadway Network
culvert clearing, etc,) were studied and
Planning Level Project Sheets were
developed. In addition to an Evacuation Plan,
completion of all phases of State Route 4
Wagon Trail, Shoulder Widening on State
Route 49 between Angels Camp and San
Andreas, Foundry Lane and Greenhorn Creek
Extension Project, Defensible Space Clearing
on State Route 49 between Angels Camp and
San Andreas, and a Unified Notification
System were chosen. Planning-level cost
estimates and project information sheets for
each project are located in Chapter 6,
Achieving a Resilient Network.

Steps that Follow
In order to move forward and achieve a
resilient transportation network,
implementation strategies, a strategic funding
plan, and allied partnerships will need to
continue to evolve. With these tools, the
region can progress and better address the
needs of our communities and better prepare
for future catastrophic events.

Hazard Planning Zones
Having a well-planned Emergency Evacuation strategy is crucial for ensuring the safety of all residents. In Calaveras County, specific evacuation zones have been identified based on factors like road accessibility, defensible space, and overall road conditions. While most people in the county live near major state routes like 4, 26, 12, or 49, there are some areas that are more remote and harder to reach. In case of a disaster, early warning, and notification is essential for the residents of these areas to evacuate safely. The county has identified seven major zones for evacuation - Zone A, Zone B, Zone C, Zone D, Zone E, Zone F, and Zone G. These zones will be used in the preparation of an Emergency Evacuation Plan.

Evacuation Zone Identifiers
In this section, a naming convention
using alphabetical order is utilized for the
general zoning conditions. It is
anticipated that there will be additional
divisions within the zones. The letters
chosen for the partitioning do not carry
any specific significance in terms of
evacuation order and were selected
randomly.

Outreach Strategy
In February 2022, a Public Outreach Plan was
developed and summarized the outreach strategy
implemented throughout the duration of the
project. The project used a hybrid approach,
incorporating online, and virtual community
engagement opportunities as well as in-person
community workshops to reach a wide array of
people and communities throughout the county.

Project Website
A project website was developed and used to present
information and make announcements. The website
had a top-down flow and was updated regularly,
leading visitors through content in an organized way.

Information included on the website includes –
• Project information and background
• Timeline of events to help the public understand
where the project is and what to expect
• Recordings of previous meetings for future
viewings
• Workshop Announcements
• Interactive survey and feedback opportunity
announcements
• Contact information for the Project Advisory
Committee (PAC)
To raise awareness of this Plan, educate the public, and provide opportunities for input, Public Outreach was conducted throughout the duration of the project. An integral part of this Plan was engaging and informing the community, giving the community a voice and hearing what they had to say.

Climate Debrief
Public officials, first responders, and other stakeholders in the region who experienced recent hazard events including wildfires, winter storms, flooding, and mudslides were interviewed during the Climate Debrief. The purpose of these interviews was to examine key challenges and constraints for evacuation and access, evaluate strategies employed, and discuss opportunities for planning and response moving forward. In addition, key successes and challenges experienced in the evacuation process were examined.

A total of four interviews with seven different participants were conducted between February 16 and February 22, 2022.

Climate Debrief Interview
“Every fire district in Calaveras had an engine present at one point or another (minus Ebbetts Pass). Outside
agencies were brought in via CALFIRE through the
mutual aid agreement, brought in, and rotated as
shifts. I believe Amador County had some engines
out there as well.“
“A lot more coordination because we learned from
the Butte Fire. We need a way to continue to train
and educate those newer people on how this all has
to work..”
Interview respondents identified four unique fire events of various scales that impacted Calaveras County in recent years, which included the Airola Fire in 2021, the Salt Fire in 2020, the O’Reilly Fire in 2020, and the Butte Fire in 2015. While the areas impacted and the duration of the wildfire events varied, there were common challenges identified during event evacuation and response. Interview participants highlighted key areas of concern during wildfire events as well as other hazard events and summarized challenges related to road conditions, access for community members and emergency responders, and capacity and resource limitations.

In addition to wildfires, several other types of hazard events were identified by interview participants. These included winter storms, flooding, and mudslides. In 2017, a large winter storm resulted in an extended road closure of a section of State Route 26 for over 30 days.

In 2019, winter storms resulted in a federal disaster declaration. Significant winter storms also occurred in December 2021, although no major State Route closures occurred in Calaveras County. In 2022, a major winter storm which flooded homes and caused created impossible roadways.

Interview respondents pointed out while major damages and threats to human safety were avoided in past hazard events, future planning will have to consider worst-case scenarios to adequately plan for events. Regular maintenance of roadways and defensible space can help keep evacuations clear and potentially reduce the threats of hazards or post-event hazards. These efforts require resources and funding, which can be a challenge. Exploring grant opportunities or other programs to support roadway maintenance and improvements will be important to address these needs.
“…Pavement can be a problem, roads are very old
out there and some of the roads are maintained by
road committees, or the owners of the land out
there, some are County-maintained.”

Survey One – Community Concerns
To fully understand the evacuation needs of
Calaveras County and supplement the climate
debrief interviews, online surveys were
prepared for three different focus groups:

Community, First Responders, and Critical
Facilities. A total of 113 residents participated
in the survey between June 20, 2022, and
September 30, 2022.
• Wildfires
• Floods
• Extreme Winter
Storms
• Extreme Heat
• Landslides
• Mudflow Avalanche
• Earthquakes
• Extreme Drought
• Other
Survey Results
Of those concerns, Wildfires,
Floods, and Extreme Drought
were the top three natural
disasters that concerned
residents the most, followed
closely by Extreme Heat.

Community members were asked
to rank the natural disasters they
were most concerned about,
including (in order) –
Additionally, community members
were asked about specific types of
conditions causing concern
including -
• Traffic Bottleneck
• Narrow Roadways
• Flooding
• One Way In, One Way
Out
• Other
Participants from around the County
dropped over 300 pins, identifying areas of
concern due to Traffic Bottlenecks, Narrow
Roadways, One Way In, One Way Out,
Flooding Issues, and other concerns based
on past experiences.
113 County residents identified
over 300 locations of concern
in the first community survey.

The layout of the surveys was similar for each
focus group, but the specific questions varied
based on each group’s unique experience.

Users opened the survey to a welcome
screen, which briefly described the purpose
of the survey and its significance. Following
the welcome screen, users were asked a
series of questions in a standard survey
format. Then, users were asked to help
identify priority corridors using an interactive
screen pin on a map; at this point, users had
the option to leave comments about why
they identified a location. In general, the
comments received reflected the sentiments
from the in-person climate debrief interviews.

Specific results from this survey were
used in the development of the Priority
Corridors and Key Considerations for
Future Evacuation Plans and discussed
further in Chapter Five.

Focus Groups and Targeted Outreach
to Disadvantaged Communities
In a joint effort with the Project Advisory Committee,
several groups within Calaveras County required
targeted outreach during the development of this
plan, including low-income, non-native English
speakers, those disabled with low mobility, and
residents with limited access to broadband/cellular
data sources. These groups have unique needs that
need to be understood and incorporated to develop
a meaningful plan. To reach these groups, efforts
were put into providing various platforms, including
the project website, Nextdoor (a website that
connects neighbors), and e-mails to stakeholders.

Existing Conditions
Assessment
42 Existing Conditions Assessment
In March 2022, an Existing Conditions Interim Report was developed; the report consolidated the existing adopted plans and guidance, local opportunities and constraints, and probable climate impacts that could be mitigated. Data was collected on existing County conditions, assets, and community characteristics. The assessment included:

Natural Hazards
According to the 2021 Calaveras County Multi-Jurisdictional Hazard Mitigation Plan (HMP), Calaveras County is affected by the following 12 hazards • Climate Change
• Dam Failure
• Debris Flows (Landslides, Mud
Flows, Avalanches, and
Erosion)
• Drought
• Earthquakes
• Flooding
• Land Subsidence (Sinkholes)
• Severe Weather – Extreme Heat
• Severe Weather – High Wind
and Tornadoes
• Severe Weather – Winter
Storms and Extreme Cold
• Volcano
• Wildfires
43 • Collection and review of emergency plans and hazard mitigation documents, including the 2021 Multi-Jurisdictional Hazard Mitigation Plan (MJHMP) developed by the Calaveras County Office of Emergency Services, the City of Angels Camp, and the Murphys Sanitary District (MSD).
• Identification and mapping of locations and characteristics of roadway assets and transportation networks, such as roadway classification and use • Identification and mapping of planned land use developments and population characteristics, including disadvantaged community status • Identification of climate change projections expected to impact the transportation network, such as precipitation, temperature, wildfire, and dam failure • Identification and review of additional case studies, reports, and reference documents
Existing Conditions Assessment
Existing Conditions Assessment
As part of the development of the 2021 MJHMP, planning and steering committee members were asked to score each hazard using the probability classifications and extent of damage to determine a score, varying from low to high risk. Table 3.1 summarizes the extent, probability of future occurrences, and risk ranking for eight hazards that may trigger an evacuation. Wildfire is the highest risk hazard across Calaveras County with a “high risk” ranking. Debris flow and flooding are the next highest risk hazard with a Serious Risk ranking. Dam failure, earthquake, and volcano hazards are Moderate to Low-risk ranking.

Flooding Critical Likely Serious
Volcano Negligible Unlikely Low
Wildfire Catastrophic Highly Likely High
Existing Conditions Assessment 44
Wildfire Risk (High Risk)
From early spring to late fall, Calaveras County is at high risk for Wildfires due to the lowlying foothills to the south and west, the Sierra ridge line to the north and east, and the general terrain and topography of the County.

In the 2018 Strategic Fire Plan For California produced by CalFire, all the major communities in the County were identified as at risk for wildfire based on fuel hazards, probability of fire, and areas of suitable housing density that could create wildland-urban interface fire protection strategy situations.

The terrain of the County makes it susceptible to wildfires. From the mountains to the valley, summer temperatures can be very hot and this in combination with the winds and different fuel types can make for perfect wildfire conditions. On the Calfire Fire Hazard Severity Scale, which uses three criteria to assess risk-fuel loading vegetation, fire weather, and topography, at least 85 percent of the county is an area of high and very high wildfire severity.

The extent of wildfire damage in
the County is rated as
catastrophic, with more than 50
percent affected and the
probability of a wildfire occurring
being highly likely. In addition to
the wildfire history that exists in
the County, projected
temperature and precipitation
changes are likely to significantly
increase the extent and severity
across Calaveras County.

According to the 2020 California
Adaptation Planning Guide,
“warmer weather, reduced
snowpack, and earlier snowmelt
can be expected to increase
wildfire through fuel hazards and
ignition risks...An increase in
wildfire intensity and extent will
increase public safety risks,
property damage, and emergency
response costs.”
Existing Conditions Assessment 45
Figure 3.1 Fire Severity Zones
Debris Flow (High Risk)
Debris flows are geological phenomena in which water-laden masses of soil and fragmented rock rush down mountainsides. Calaveras County is especially susceptible to the occurrences due to the history of wildfires and recently burned forests. In Calaveras County, there are three basic types of hazardous debris flow, including, landslides, mudflows, and avalanches.

Landslides
A landslide is a gravity-driven down-slope
movement of soil and rocks at varying
speeds. In general, landslides are caused
by disturbances in the natural stability of a
slope, they can accompany heavy rainfalls,
or follow droughts and often occur in burnscarred areas where wildfires occurred in previous years.

Calaveras County’s terrain and soil types
create a condition with a high probability
of landslides to critical extents. In recent
years, the county has had several
damaging landslides. In 2015, a heavy
rainstorm and high mountain snow in the
burned areas from Butte Fire caused
property damage from debris and
mudflows. In 2016, heavy rains on State
Route 26 between Mokelumne Hill and
Glencoe (within the Butte Fire Area),
caused property damage from debris
flows. Storms in February 2019 caused a
landslide that closed three miles of State
Route 26 for 69 days (about 2 and a half
months) and cost $3.5 million in repairs.

Most recently, in March 2023 an unknown
amount of property damage was caused
by debris flowing to several houses and
roadways in West Point.

Mudslides develop when water rapidly
accumulates in the ground and results in
a surge of water-saturated rock, earth,
and debris. It is a process characterized
by the mass movement of fine-grained
materials with a high degree of fluidity.

Like landslides, mudflow in Calaveras
County has a high probability with a
critical extent due to the steeply sloped
terrain and silty soils. Several large and
disastrous mudslides have occurred in
the County such as the 1997 event. The
slide started near State Route 4 and
Cottage Springs and slid one and a half
miles into the Stanislaus River, taking out
roads, a bridge, and service facilities. In
2015, heavy rain and snow in burned
areas from the Butte Fire caused road
closures, overtopping of bridges, and
property damage.

Mudflows have a powerful potential to
impact life and property on a much
larger scale. Mudflows can block roads,
take down utilities, move buildings from
their foundations, and cause injury or
death to persons caught in the path.

Mudslides
Existing Conditions Assessment 46
Existing Conditions Assessment 47
Figure 3.2 Copperopolis Fire Protection and Calaveras County Public Works gather at Black Creek and Copper Cove Drive. Photo courtesy of Noah Berner- Calaveras Enterprise Calaveras County has a risk for several types
of flooding, including riverine, flash, and
stormwater, all with likely probability and
critical extents. Flooding in the County
jeopardizes areas along the Mokelumne,
Calaveras, and Stanislaus Rivers and the
county’s numerous streams, channels, and
creeks.

Riverine flooding typically occurs when a
waterbody overtops or surpasses its
capacity limits due to a combination of
prolonged rainfall and/or snowmelt. In
Calaveras County, the risk for riverine-type
flooding occurs between November and
April.

Unlike riverine flooding, flash flooding
typically happens very quickly, and
evacuation time and planning are much
more limited. Enormous volumes of water
flow over a short time and occur from heavy
rainfall with restricted drainage areas.

Stormwater flooding occurs in areas that
have increased runoff from impervious
surfaces and inadequate drainage systems.

Calaveras County’s steep elevation reducing
terrain from the Sierra to the Valley creates a
complexity for drainage systems.

The County has a history of flooding events,
in 2012, 2017, 2018, 2019, 2021, 2022 and
2023. In 2019, State Route 49 was shut
down for hours due to flash flooding and
residents were trapped in their homes. The
County was included in a federal disaster
declaration that year and with each
intensifying event, flooding damage costs
increase. During the development of this
report, two additional instances occurred. In
one instance a search and rescue team was
required to save a couple from their home in
Sheep Ranch. In the second instance,
Copper Cove Drive was closed due to flash
flooding.

Analysis of Hazard Risk
and Vulnerability
48 Analysis of Hazard Risk and Vulnerability
In August 2022, a Hazard Risk and Vulnerability Assessment was prepared as part of the Calaveras County Evacuation and Access Needs Assessment and Preparedness Plan. The Hazard Risk and Vulnerability Assessment evaluated the susceptibility of Calaveras County’s communities and transportation assets to natural hazards. The key focus of the assessment was to identify areas within the County and its communities and assets that may experience adverse impacts due to natural hazards that impair the County’s ability to facilitate evacuations and emergency response activities.

Since communities and transportation assets are affected differently by hazards, two separate assessments were developed to achieve appropriate results. The Community Assessment focuses on impacts on people by examining the vulnerability (the potential of Calaveras Communities to experience adverse impacts) and the Transportation Asset Assessment focuses on the impacts on the County’s overall transportation network by examining the risk to roads and bridges.

Both assessments used a relative framework that assigned scores compared to the rest of Calaveras County. The score comprises multiple components that contribute to a community’s or assets’ overall likelihood of enduring damage or disruption due to hazards. Each of the components was characterized through a set of indicators that represent the scale of potential impacts.

The Community
Assessment
The Transportation Asset
Assessment
Geographic areas are populated by
individuals, businesses, and
governmental and non-governmental
organizations.

Physical structures, including roads and
bridges provide essential services, such
as evacuation, emergency response, and
movement of goods and people.

Hazard Risk and Vulnerability 49
Figure 4.1 Community and Transportation Assessment graphic The Community Assessment
The Community Assessment examined the County’s geographic communities and residents by characterizing vulnerability to potential hazard impacts. To determine a vulnerability score, community exposure and sensitivity were analyzed.

Vulnerability = Exposure x Sensitivity
Vulnerability – the
overall degree to which a
community is expected to
experience adverse
impacts due to hazards.

Vulnerability is a function
of exposure and
sensitivity.

Exposure – refers to the
likelihood and degree to
which physical contact
between a hazard and a
community will occur.

This component
incorporates hazard
characteristics, such as
frequency, intensity,
geographic scale, and
external factors that
affect event severity.

Sensitivity – refers to
the degree to which a
community can cope
with hazard impacts.

This component
incorporates the
composition of the
community that
influences its capability
to prepare for, respond
to, and bounce back
after a hazardous
event.

Using readily available datasets that provide information consistently across geographic areas, metrics are used to quantify various indicators that form each component. Each community is assigned a metric score ranging from a value of one (lowest relative to the County) to five (highest relative to the County). Metrics are weighted equally and then averaged to produce a single component score ranging from one to five. The component scores are multiplied to produce a single Vulnerability Score.

Communities exhibiting the highest hazard exposure are rural and higher elevation areas east of State Route 49. These communities include Dorrington, West Point, San Andreas, Mountain Ranch, Sheep Ranch, Paloma, Mokelumne Hill, and Vallecito. Higher exposure scores were driven primarily by high exposure to landslides and wildfires.

Communities exhibiting the highest sensitivity are rural areas located centrally in the County.

These communities include Douglas Flat, White Pines, Wilseyville, Mountain Ranch, Glencoe and Railroad Flat. High sensitivity scores are driven by a high concentration of census tracts meeting the thresholds for Disadvantaged Communities and Economically Distressed Areas.

Mountain Ranch received the highest Vulnerability Score of all communities due to high exposure to wildfire, landslides, and high sensitivity, driven by disadvantaged communities and economically distressed area indicators. Most Communities exhibiting high vulnerability are rural communities in the northeast part of the County. In contrast, communities exhibiting the lowest vulnerability are those in more developed areas along the County’s southwestern boundary.

The Transportation Asset Assessment
The Transportation Asset Assessment examines the susceptibility of the County’s transportation assets to potential hazard impacts by characterizing risk. An asset’s risk to hazard impacts is a function of two components: vulnerability and criticality. = Vulnerability
Exposure Sensitivity
Risk f( Criticality ) ,
Risk – refers to the
potential for adverse
consequences where
something of value is at
stake, and the occurrence
and degree of outcome
are uncertain.

Criticality – refers to the
importance of an asset to
the surrounding
community. This
component incorporates
indicators related to an
asset’s significance to the
larger transportation
network, such as its
frequency of use.

Risk scores are assigned using a lookup matrix which assigns higher weights to more critical assets, reflecting their relative importance to Calaveras County and its transportation network.

The Transportation Asset Assessment considers two types of transportation assets:
roads and bridges. The roads dataset was obtained from Calaveras County Open Data Portal and the bridge assets were downloaded from the 2021 National Bridge Inventory. The process for evaluating the sensitivity and criticality of each asset type varies based on the asset characteristics and functions.

Roads exhibiting the highest vulnerability are clustered in West Point along State Route 26 on the County’s Northern border and Camp Connell along State Route 4 on the southeast border. These results correlate with previously identified at-risk routes determined through the Climate Debrief Interviews conducted to develop the Preparedness Plan. Overall, in these areas, high vulnerability is driven by high wildfire exposure and the presence of predominantly unpaved roadways. The communities surrounding these roadways also exhibited the highest community Vulnerability Scores in the County.

Calaveras County’s most critical roadways include segments of Angels Camp Main Street, West St. Charles, and State Routes 4, 12, 26, 49. These roads have higher traffic capacities and are essential to the County’s overall transportation network. During the Climate Debrief Interviews, Calaveras officials identified State Route 4 as a critical road for ingress and egress during evacuations. Many roads in rural areas exhibit low criticality scores. These roads may be necessary to nearby communities, but they likely have limited capacity and connections to other vital roads in the County’s transportation network.

Priority Corridors and Key
Considerations for Future
Evacuation Plans
64 As part of this plan, a Priority Corridors and Key Considerations for Future Evacuation Plan identified residents’ priority routes and communications during an evacuation event. Replica®, a web-based data platform, and MetroQuest, an interactive survey platform were utilized and helped draw conclusions about the existing roadway network and communication systems in place.

Priority Corridors
A critical component of the Evacuation and Access Needs Assessment and Preparedness Plan, is understanding the County’s current roadway network use, i.e, which roads does the community rely on? Which roads are used as bypasses or parallel routes? Which roads have the highest volume of traffic?
Replica®
The web-based data platform utilizes GPS-based data from smartphones and vehicle computers to understand
roadway demographics including, who is traveling on the road and what they are traveling for. Data filters allowed the platform to highlight exit routes and the percentage of vehicles on each road. For this project, filters were applied to only report the following:
• Trips by Calaveras County residents
• Starting at their home location
• Traveling a distance greater than 15, 30, 45, 60 miles The Replica platform uses a
combination of actual data
and algorithms to create a
travel pattern model. These
models provide less-thanperfect vehicle counts but
provide highly reliable
percentages. Data tabulated
in this Chapter are entirely
shown as percentages. The
data is based on an average
Thursday in the Fall of 2021
under non-emergency
conditions.
65 Figure 5.1 Replica Model Preferred Routes of Residents Leaving the County Priority Corridors and Key Considerations for Future Evacuation Plans The model illuminated several County maintained
roads that are used as direct routes through and
out of the County. The rationale behind this is due
to Calaveras County’s unique characteristic of
having only one incorporated City, and many
Census-Designated Places (CDPs). Each local
roadway exiting CDPs was evaluated, and the
percentage of traffic was reported. As a result,
these local roads should be given priority in future
evacuation plans.

CDPs are statistical geographic
entities representing closely settled,
unincorporated communities
recognized and identified by name.

CDPs in Calaveras County include
Arnold, Avery, Burson, Copperopolis,
Dorrington, Douglas Flat, Hathaway
Pines, Mokelumne Hill, Mountain
Ranch, Murphys, Railroad Flat,
Tamarack, Vallecito, Valley Springs,
and West Point.

Priority Exit Routes
Four, two-lane state routes and three local roads serve Calaveras County as primary exit routes. State routes
include State Route (SR) SR-4, SR-49, SR-12, and SR-26.

Local Roads include O’Byrnes Ferry Road, Parrotts Ferry Road, and Milton Road. SR-4, 12, and 26 run east-west,
with SR-4 being the only route to exit the County’s
eastern boundary. SR-12, 26, and 4 exits the County’s
southern border. SR-49 is the only north-south running
route. However, SR-26, which is generally east-west,
turns north at its eastern end, crossing the county
boundary 12 miles east of the SR-49 county exit.

Altogether, these routes provide ten entrances and exits from the County.

In addition to the priority exit routes, it is important to note the westside, north/south connection corridor,
Burson Road, from Camanche Parkway to Milton Road
which provides an alternative route for State Routes, 4, 26, 12, and 88. This connection is crucial and allows
emergency response teams an alternative route,
avoiding bottlenecks and road closures on the State
Routes.

The state routes are maintained
by Caltrans, which staffs four
maintenance facilities
throughout the County. These
facilities are in Angels Camp
(SR-49), West Point (SR-26),
Camp Connell (SR-4), and
Cabbage Patch (SR-4, winter
only). The County Public Works
department maintains local
roads and has facilities located
in Arnold, Valley Springs, and
San Andreas. The City of Angels
Public Works Department
maintains local roads in the City
limits.

Table 5.1 summarizes the results from the Replica
model for the ten roadways that can be used to exit
the County. To adequately capture data that is
representative of the County, the model was run for
four different scenarios with traveling distances set at 15, 30, 45, and 60 miles, respectively. The purpose of
running the model with varying traveling distances was
to make certain all residents are included whether they live close to the County border (West Point residents), or further from the County border (residents from
centralized communities). Figure 5.5 shows the five
most utilized exit routes based on the Replica Model
and the average use of the routes by residents leaving
the county.

• Trips that start from Calaveras County;
• Trips that conclude in counties other than Calaveras County; and • Traveling a distance greater than 15, 30, 45, and 60 miles.

Priority Corridors and Key Considerations for Future Evacuation Plans 69 Sources: Caltrans 2019 Traffic Volumes AADT and Replica.

The data run reveals that for residents traveling 15 miles or more to leave the County, 21% of residents use SR-12, 17% of residents use both SR-49 (north) and SR-26 (southwest) and 12% of residents use SR-4 (west). Each of the remaining corridors are utilized less than 10% for residents leaving the County.

Results for residents traveling 60 miles or more to leave the County indicates that SR-4 (west) is utilized the most with 36% of residents using the route. 28% and 13% utilize SR- 12 (west) and SR-26 (southwest), respectively. Less than 10% of residents utilize each of the remaining routes.

The average percentage from all travel distances revealed SR-12 (west) being the most used corridor with 27% of residents choosing the route as a county exit. SR-4 (west), SR-26 (southwest) and SR-49 (north) had average percentages of 25%, 16% and 10%, respectively.

The SR-12 route provides the shortest path to Sacramento, while both SR-26 and SR-4 lead to Stockton. SR-49 serves as a primary connector for the respective State Routes. All four roadways offer access to SR-99 and Interstate-5 (I-5), both regionally significant north-south freeways used to access California's central Valley. SR-4 ultimately connects to the San Francisco Bay Area.

After analyzing the County’s priority exit corridors, the model was refined to understand the exit routes for each populated area. Most residents rely on State Routes as primary exit routes throughout the county, however, some residents, located in the northern and central county, rely on County maintained roads to access the State Route system.

Priority Corridors and Key Considerations for Future Evacuation Plans 71 Priority Local Roads
State-maintained routes pass through
most population centers in Calaveras
County. While having a State Route
double as a Main Street has
disadvantages, the trade-off occurs with
improved access. Caltrans maintains highquality roads through evolving design criteria and continuous investment.

However, the County does not have
access to the same resources, so County
roads do not evolve at the same pace.

Table 5.3 includes several Calaveras
County Communities that do not benefit
from direct access to a State Route. These
communities are Mountain Ranch, Sheep
Ranch, and Rail Road Flat. Therefore,
these communities will require special
consideration while developing an
Evacuation Plan.

An interesting observation from this
community-focused model run is that
residents on the SR-4 and SR-12/SR-26
use the connection of SR-49 between San
Andreas and Angels Camp to cross to
other routes. SR-49 between San Andreas
and Angels Camp is a heavily traveled
roadway segment; therefor this roadway
segment also merits careful consideration
for evacuation.

Most Calaveras County communities have less
than four viable exit routes and even the
communities with more than two exit routes rely
heavily on one or two primary roadways, with
the third used by single-digit percentages of
the population.

In addition to State Routes, several two-lane
local roads are used as parallel routes,
bypasses, and arterial roadways. Table 5.3
identifies key local roads, their direction, and
the communities they serve.

Priority Corridors and Key Considerations for Future Evacuation Plans 72 To fully understand the evacuation needs of Calaveras County and supplement the stakeholder interviews, online surveys were prepared for three different focus groups:

Community, First Responders, and Critical Facilities. In this section of the Plan, we will discuss the results of the survey. In the Project Advisory Committee and Public Outreach Chapter of this Plan, participation results were discussed.

MetroQuest
Survey Focus Groups
Community First Responders Critical Facilities
Figure 5.6 shows that Wildfire, Extreme Winter Storms, and Extreme Drought are the natural disasters that concern residents the most, followed closely by extreme heat. Of these concerns, wildfires are the only disaster that appears unexpectedly, minimizing the time residents must evacuate. While all events are cause for serious concern, most of the comments received related to the County’s roadways and capacity to accommodate sudden significant evacuations due to wildfire events.

What Type of Event Concerns you Most?
73 Figure 5.6 What Type of Event Concerns you Most?
Priority Corridors and Key Considerations for Future Evacuation Plans Modes of Transportation
When asked about the type of transportation residents relied on, the overwhelming majority relied on private passenger vehicles for transportation, with just one survey taker relying on public transportation. Informal discussions with residents during an in-person event highlighted several types of facilities where residents cannot drive and would require commercial vehicles for transport. The facilities mentioned were primarily resident care homes and senior living facilities. While Hospitals and correctional facilities have unique needs that need to be considered in individualized evacuation plans, Calaveras transit (Calaveras Connect) has vehicles that can assist with targeted residential evacuations. Including Calaveras Connect as an option in residential evacuations has the added benefit of reducing the number of singleoccupancy vehicles on the roadway network during evacuation events. Early coordination with transit should be considered in care facilities' evacuation plans.

All focus groups were asked which roads were the highest priority to be maintained for evacuations and access. Figure 5.8 shows the results of this question. Interestingly, the top four results mirror the results presented in Chapter 1 – Survey One. However, other local roads were identified by many survey takers as high-priority roads. This discrepancy exists because while other roads do not carry much traffic, they are the only routes available to communities with no State Route access. Therefore, the roads serving the communities of Sheep Ranch, Mountain Ranch, and Railroad Flat merit special consideration in developing a county-wide evacuation plan.

about how their residents will respond
during an evacuation event. Both surveyed
groups responded that Calaveras County
residents are not well notified during an
event, do not know what to do, and do not
know where to go. While out of the scope of
this initiative, a well-publicized and utilized
resident notification platform is
recommended.

An excellent suggestion through the first
responder's survey was creating an alert
system for Air B&B’s and a geofenced alert
system that would push alerts to anyone with
a cell phone within a certain area. An alert
system cannot rely on cell phones alone
because many areas have poor or no cell
phone service and cell towers tend to “crash”
when power is out.

When the First Responders were asked their
opinion of the functionality of the Counties
Evacuation Routes, the common response was
two stars on a scale of one to five, with five
being the highest score. This ranking indicates
that the Counties evacuation routes'
functionality needs improvement.

First Responders and Critical Facilities were
asked which roadways present the most
significant challenges to evacuation
operations; the responses mirrored that of
the general public's reactions. Figure 5.18
shows that State Route 4 was overwhelmingly
identified as the route that posed the most
significant difficulty for evacuation events.

While Evacuation Routes and Resident
Communication were identified as areas that
need improvement, the First Responders
indicated that they are generally well-trained
for Evacuation Events, with no one-star
responses and some five-star responses to
this question. Interestingly, when presented
with a variation of this question, changing
the word “training” to “preparation” the
positive response decreased with a portion
of the group giving one star to the
preparation question, and no five-star
responses.

Achieving a Resilient
Network
83 The final chapter of the Calaveras County Evacuation and Access Needs Assessment and Preparedness Plan (CCEANAPP) presents strategies for implementing the information discussed in the previous five chapters. It outlines steps for achieving implementation, identifies funding sources, and prioritizes projects to establish a robust transportation network.

These tools will help the region progress and meet the needs of our communities while working towards a continually evolving resilient transportation system.
84 Implementation
Strategies
85 To continue moving towards a more resilient transportation network, ongoing strategic planning is required. Through the analysis phase of this project, we were able to determine high-risk and vulnerable communities and roadway infrastructure, which aided in the development of resilience projects that will benefit the community and better prepare Calaveras County for future disastrous events. The Project Advisory Committee provided feedback and ranked the projects to help determine the most beneficial projects to Calaveras County. Based on the feedback, planninglevel project fact sheets have been developed to prepare for future funding opportunities, a crucial element in building a resilient network. In addition to building resilient infrastructure, ongoing public events and outreach will occur to educate the public and unify the communities throughout Calaveras County.

Prioritization
Achieving a Resilient Network
To achieve our goal of creating a stronger and more adaptable transportation network, it's crucial to give priority to projects that can respond to, prepare for, and minimize the impact of catastrophic events and scenarios. Therefore, we must prioritize Resiliency and Hazard Mitigation Projects to ensure that funding opportunities are not missed. This section covers different types of projects, such as major, minor, and planning projects.

Major Infrastructure Projects
Minor Infrastructure Projects
Planning Projects
Major infrastructure improvements typically cost several millions of dollars and take several years to develop.

Minor infrastructure projects generally cost less than a million dollars and can be implemented within a year or as ongoing maintenance.

Planning Projects can be used to prioritize a program of projects or develop strategies to manage potential emergency events. 87 Project Prioritization

* Projects with an asterisk were identified as priority projects. Project fact sheets were developed for these projects and included later in this section.
89 We identified Defensible Space Clearing and Hazard Tree Removal Projects by using aerial views from County roads and State Routes. We marked locations with less than 10 feet of defensible space on both sides of the road. Through this process, we discovered 76 County Road projects and 121 State Route Projects that require attention. You can view a visual representation of these locations on the Defensible Space Clearing and Hazard Tree Removal Projects Map below. For a full-size map, please refer to Appendix B.

92 By leveraging data from FEMA and the 100-year floodplain, we were able to identify at-risk areas, including roadways that are prone to flooding. These locations, where the floodplain intersects with a road, have been earmarked for future repair projects to prevent flooding. Some of these areas experienced flooding this winter due to record-high rainfall. For a comprehensive map, please refer to Appendix B.

Achieving a resilient transportation system in Calaveras County will require more resources and funding than is currently budgeted and available. From the priority projects outlined in this Plan alone, the County will need millions of dollars.

The prioritized major, minor, and planning projects mentioned in this Plan are based on the existing conditions and will help mitigate disaster during future catastrophic events. Creating a more resilient Calaveras County will require a combination of supplemental funds for individual transportation-related projects and the partnership and cooperation of individual property owners.

Even then, we understand the projects mentioned do not represent the entirety of what is needed to protect our Calaveras Communities.

We can’t afford the
cost of doing nothing.

State and Federal Funding Sources
The State Route system revolutionized the movement of goods and people across the country. Because mobility continues to be an economic differentiator, local, state, and federal governments invest in transportation infrastructure. In recent years, funding has been focused on making the transportation system more resilient against natural disasters. As such, many competitive funding programs exist to supplement local budgets for compelling local projects.

Specifically, the U.S. Department of Transportation and the State of California provide funding through the PROTECT (Promoting Resilient Operations for Transportation Efficiency and Cost Saving Transportation) program. This program provides funding to ensure surface transportation resilience to natural hazards and disasters through planning and infrastructure.

Competitive Funding Sources for Resilient Transportation Infrastructure
Achieving a Resilient Network
In addition, the Federal Emergency Management Agency manages annual programs for Hazard Mitigation assistance grants. FEMA funding is directed at projects that will reduce future disaster recover costs.

Implementing Priority Projects
We are dedicated to establishing resilient transportation infrastructure through ongoing project implementation. Our team is actively seeking funding opportunities like PROTECT and the Hazard Mitigation Grant Program (HMGP).

Several projects, including the State Route 4 Wagon Trail, Foundry Lane and Greenhorn Extension Project, and a County-Wide Evacuation Plan, are currently in progress and preparing for the next phase of execution.

Achieving a Resilient Roadway Network
Our region's transportation network is becoming more resilient thanks to the Evacuation and Access Needs Assessment and Preparedness Plan. This important initiative has helped us identify vulnerabilities, risks, and challenges unique to our area. By engaging with the public, we have identified primary roads and evacuation routes while also recognizing the specific challenges each roadway presents. As a result, we have developed a comprehensive list of resiliency projects that prioritize the most valuable initiatives and enable us to plan and prepare for funding opportunities.

We understand that more public outreach, data analysis, and proposed projects are necessary to achieve our goal of enhancing the resilience of the Calaveras roadway network. We are committed to working towards this objective.

We want to extend our sincere gratitude to the Project Advisory Committee, emergency responders, critical facilities, and community members who shared their valuable insights and feedback during the creation of this plan. Your contributions were instrumental in making this project a success, and we are truly grateful for your support.

Climate Debrief Interview Summary Report
2 1. Introduction
The Calaveras County Council of Governments is developing an Evacuation and Access Needs Assessment and Preparedness Plan for Calaveras County. In support of this effort, Dewberry conducted climate debrief interviews with stakeholders who experienced recent hazard events, including wildfires, winter storms, flooding, and mudslides. The objectives of the climate debrief interviews were as follows:
(1) interview relevant public officials, first responders, and other stakeholders in the region who could provide input on recent extreme climate events; (2) examine key challenges and constraints for evacuation and access, evaluate strategies employed, and discuss opportunities for planning and response moving forward; and (3) examine key successes and challenges experienced in any evacuation processes. The Dewberry team extended email invitations to 25 different stakeholders representing various organizations and roles in natural hazard management and response in the County. Table 1 summarizes the list of interview participants. A total of four interviews with seven different participants was conducted between February 16 and February 22, 2022.

In addition to wildfires, several other types of hazard events were identified by interview participants.

These included winter storms, flooding, and mudslides. In 2017, a large winter storm resulted in an extended road closure of a section of Highway 26 for over 30 days. Significant winter storms also occurred in December 2021, although no major highway closures occurred in Calaveras County. 3 Source: https://www.mymotherlode.com/news/local/1207159/75-percent-containment-on-saltfire.html#foobox-1/0/saltfire-1.jpg 4 Source: https://www.mymotherlode.com/news/local/1165540/arson-being-investigated-in-oreilly-fire-inangels-camp.html#foobox-1/1/OReilly-Incident-fire-in-Angels-Camp-11.jpg 5 Source: https://wildfiretoday.com/wp-content/uploads/2015/09/Map-Butte-Fire-9-12-2015-CAL-FIRE570x432.jpg Climate Debrief Interview Summary Report

3. Event Evacuation and Response
Evacuations occurred during each of the four wildfire events identified by interview participants. While the areas impacted and duration of the wildfire events varied, there were common challenges identified during event evacuation and response. Interview participants highlighted key areas of concern during wildfire events as well as other hazard events and summarized challenges related to road conditions, access for community members and emergency responders, and capacity and resource limitations.

3.1 Evacuation Routes
While evacuation routes have been mapped across Calaveras County, these routes have not been documented in an evacuation plan. Interview participants noted roads that are critical for ingress and egress during an emergency event. This includes Highway 4, particularly the upper corridor from Ebbetts Pass to City of Angels Camp. In addition to wildfire concerns, the upper Highway 4 corridor has historically had issues during winter storm events, especially if any trees/limbs or power lines block the ability for snow plows to access this route. Highway 49 was also identified as a concern for evacuations. During the 2020 O’Reilly Fire, Highway 49 was shut down for approximately 3-4 hours.

Highway 49 also crosses over Angels Creek on an old two-lane bridge at the southern end of the City of Angels Camp. If this bridge is impacted at all during an event, the only alternative is for people to travel east or west for several miles to be able to evacuate.

Around Angels Camp, interview participants noted several other areas where roadway access is challenging during a natural hazard event, including Birds Way, Finnigan Lane, Bush Street, Echo Street, Crystal Street, and Big Horn Mobile Park. Participants noted several subdivisions with limited access, including Greenhorn Creek and Stelte Park near Angels Camp and Forrest Meadows near Ebbetts Pass. Many of these subdivisions have gated access points, which can pose challenges in emergency situations.

In the Copperopolis Fire District, specific areas mentioned with limited access routes include Little John Road, Kiva recreational area, Diamond XX, Circle XX, and Bar XX neighborhoods. In addition, there is a bridge over Lake Tulloch that provides that only exit route to Tuolumne County. There have been several occasions where a truck has hit the bridge abutment, requiring closure of the bridge and restricting access to this evacuation route. If critical bridge crossings like these are impacted, major re-routings could cause significant traffic delays during an evacuation event. 6 Source: https://www.mymotherlode.com/wp-content/uploads/2019/02/hway26e-1.jpg Climate Debrief Interview Summary Report

Climate Debrief Interview Summary Report
7 3.2 Road Condition Challenges
Given the historic infrastructure of the County, especially in the City of Angels Camp, roads are often narrow and not built to modern standards. This causes challenges for simultaneously trying to provide access for emergency responders and residents trying to evacuate. The City of Angels Camp also has a two-lane bridge, last refurbished over 70 years ago, that crosses over Angels Creek along Highway 49.

This route is critical to southbound evacuation during a natural hazard event, and interview participants noted there is a need for an alternative route.

Across Calaveras County, poor road pavement conditions or unpaved roads can also be a challenge. In communities with homeowner associations (HOAs), the roads can be privately maintained, and in select areas, emergency access roads for the community subdivisions are unpaved or gated.

3.3 Access Challenges
For several subdivisions, only one paved road provides access to the community. This creates challenges with traffic flow and re-routing in the event of a road blockage. Secondary hazards, such as fallen trees or limbs, power lines, and mudslides can limit road access. During the winter storms of 2017, a mudslide occurred that created a road blockage and trapped a vehicle along the route. When road blockages occur, participants noted there is a lack of alternative roads for re-routing, or limited redundancy. In addition to secondary hazard road blockages, parked cars along the narrow streets of the City of Angels Camp can restrict roads to one-way access. Community access gates also create access barriers to residential subdivisions.

3.4 Capacity and Resource Challenges
Staff capacity, including the amount of people on duty, can be a limiting factor for emergency response within Calaveras County. Participants noted that communities rely on each other for routine needs to address capacity and resource challenges. The start of the COVID-19 pandemic in 2020 also exacerbated staffing challenges in select situations. For example, during the winter storm events in December 2021, Caltrans experienced staffing shortages from COVID-19 impacts that affected response capabilities. The Copperopolis Fire Protection District also experienced staffing shortages in summer 2021 when extreme heat caused exhaustion issues. COVID-19 limited who could be on duty at the time, resulting in staffing challenges.

In remote areas of Calaveras County, water access is limited. For example, during the Salt Fire, portions of the County were impacted where no fire hydrants are available, and water had to be sourced from elsewhere. For winter storm events, there are additional resource considerations for residents who may be snowed in. One interview participant noted the importance of pre-event messaging to ensure people have enough water, food, and fuel to withstand multiple days of potentially being stuck at home during a winter storm event.

4. Coordination Between Responding Groups
Multiple agencies and organizations are involved with response to hazard events across Calaveras County. These include local municipal departments, such as Calaveras County Office of Emergency Services (OES) and City of Angels Camp Fire Department, state agencies, such as the California Department of Transportation (Caltrans), California Highway Patrol (CHP), and California Department of Forestry and Fire Protection (CAL FIRE), and non-profit groups. Interview participants shared successes and challenges with coordination between responding groups during previous hazard events.

4.1 Successes
A major success noted by multiple interview participants was that no one was hurt during the majority of the hazard events that were discussed. Across these events, people were able to evacuate quickly enough to avoid harm. While some assets were destroyed or damaged, none of the interview participants identified any critical infrastructure impacted during any of the events.

Climate Debrief Interview Summary Report
8 Participants highlighted the successes of the City of Angels Camp, Calaveras County, and CAL FIRE coordination in responding to the 2020 O’Reilly Fire and containing it within 3-4 hours. During the 2020 Salt Fire, an interview participant noted the dispatch and mutual aid plan across the County worked seamlessly and helped secure resources from outside of the County. Communication throughout the Calaveras County Schools system worked well during the 2021 Airola Fire, and updates were delivered to parents and students almost daily.

At the state level, Caltrans relies on CHP and the local Sheriff’s Office to provide information on where traffic control support is needed. During winter storm events, this has supported Caltrans teams with quickly providing road signage and distributing updates through Changeable Message Signs (CMS).

4.2 Challenges
Given the large extent of the 2015 Butte Fire, many jurisdictions, agencies, and organizations were involved in coordinating a response. At the time of the Butte Fire, mutual aid agreements did not exist across Calaveras County, which caused challenges in coordinating a response. Since 2015, mutual aid agreements have been established to improve response coordination.

Non-profit organizations, such as the American Red Cross, have also provided volunteers or resources to establish emergency shelters and aid in post-event recovery. Participants noted a better mechanism needs to be established for coordination between local governments and volunteer organizations to improve effectiveness of these efforts.

Across Calaveras County, there are currently limitations with communication between emergency operations/command centers and first responders in the field during a hazard event. First responders will relay conditions to the emergency command center to initiate evacuations. The County is researching the potential to migrate to a cloud-based system, such as Zonehaven, that would streamline communication of conditions and evacuation requests. The Sherriff’s office also plays a role in directing people where to evacuate, adding a third level of coordination. Law enforcement can communicate via dispatch radio; however, Caltrans does not have the same capability and noted a better line of communication with first responders would be helpful. Caltrans interview participants noted that communication generally has to go through their traffic management center, which takes more time and may result in resources not being deployed as quickly as if direct communication went to the emergency operations staff.

4.3 Opportunities for Improvement
The creation of an evacuation plan can help identify roles and responsibilities for all agencies involved in coordinating evacuations and response during hazard events. Currently the County and City lack a plan for routine training drills and exercises focused on natural hazard incident planning and response. Several participants emphasized the importance of training and opportunities for improved frequency of training offerings. Caltrans has full emergency operation capabilities, but that is not always communicated to local partners. By involving Caltrans in County training drills, the resources Caltrans offers could be better understood and utilized by local partners. Non-profit organizations involved with event response could also be included in these drills to support improved coordination.

Participants noted that local knowledge of previous event responses has been lost with staff turnover.

Hazard planning and response training resources could help address this gap and support knowledge transfer between staff.

Interview participants also noted opportunities to improve outreach with community members around actions they can take before and during a hazard event. For example, the Copperopolis Fire District is preparing an outreach campaign to encourage individual actions that promote fire safe communities, such as maintaining defensible space and having an evacuation plan. Key audiences include HOAs, road committees, and community groups. Subdivision HOAs across the County can also support improved access during a hazard event by having a plan for opening gates and maintaining emergency access roads.

Climate Debrief Interview Summary Report
9 5. Communication with the Community
During recent hazard events, responding agencies used various methods for communicating with the community. The methods and messages depended on the hazard, timing of the event, and whether evacuation was required.

5.1 Existing Communications Tools

5.1.1 Everbridge
The main communication alert system used by Calaveras County OES is the Everbridge system (CALAVERAS ALERT Emergency Notification Program). This system allows Calaveras County OES to alert residents and businesses by telephone, cell phone, text message, email and social media when there is a threat to the health or safety of Calaveras County residents, and is used when evacuation alerts are necessary.

The Everbridge system can be effective in communicating alerts to the community, but it requires people to sign up for system alerts. As of February 16, 2022, the Everbridge system had 21,062 individual contact points (which represents about half of the 45,292 population for the County). Alerts can be sent to the whole system or portions depending on their location. For example, in the case of the O’Reilly Fire incident, an Everbridge evacuation notice was sent out to just over 200 contacts in the affected area. When evacuation orders are lifted, the Everbridge system will rebroadcast to the same contacts. In addition, the system does geofencing. This means that if you are an Everbridge customer and have the Everbridge app, it will notify you with alerts if you happen to be in an affected area when an event happens (even if you are not a resident of that area).

5.1.2 Nixle
The Calaveras County Sheriff’s Office utilizes the Nixle community notification service. This web-based service is a geographic-based public notification system for residents of Calaveras County. An address is required as the basis for sending messages relevant to the neighborhood. Once registered, residents can receive email and text messages alerts from the Sherriff’s Office. Similar to the Everbridge system, it requires users to sign up in order to receive any notifications.

5.1.3 Social Media
Some of the public agencies within Calaveras County leverage social media platforms for communicating with the community during hazard events or evacuations, though this generally is done on an as-needed basis. For example, Calaveras OES did leverage social media releases during the O’Reilly Fire incident after the Everbridge alert was sent out. The City of Angels Camp has plans to revamp their website and will be creating a Facebook page to help keep people notified for future events through those methods.

Residents tend to share information through social media platforms like Facebook, Nextdoor, and others. Several interview participants noted that community members may share details about a fire or road closure much faster than responding agencies can share information. Due to the nature of social media, this information can be shared and updated very quickly across the community.

5.1.4 Door-to-Door or Word of Mouth
When evacuations are necessary during hazard events, responding agencies often will go door-todoor in affected areas to ensure that residents are informed and able to evacuate. In some cases, this is done by the Sherriff’s office, but police and fire departments are also often on the scene and able to communicate directly with residents by going door-to-door. With fire events being very dynamic and rapidly changing, going directly to residences and businesses is often the most efficient way to communicate information. This method is also used in some cases with events that have more time for planning and response, such as winter storms or flooding. For example, in areas that are known to flood within the City of Angels Camp (e.g., Birds Way), responding agencies may go to Climate Debrief Interview Summary Report
10 residences ahead of time to let people know where they may be able to go for temporary housing needs in the case of displacement.

Several interview participants noted that they also received information about hazard events through informal communication with other community members. In the case of a fire, for example, community members may hear from their neighbors or others in the area that an evacuation is occurring, a road is closed, etc. Informal word-of-mouth communication is frequently used by community members to share rapidly changing information as these events unfold.

5.2 Communications Challenges
As noted above, the main alert notification systems used by Calaveras County are Everbridge and Nixle. While these systems can be effective in sending out evacuation alert notifications or other important communication updates during hazard events, they have several limitations. The first is that these systems are primarily organized by the County, so other responding agencies (such as City of Angels Camp staff, fire protection districts, or other County departments) need to coordinate with the County to send out messages. Secondly, while these systems are geofenced, they require enrollment in order for community members to receive alerts. As noted by one of the interview participants, the number of Everbridge contacts currently only represents about half of the population of the County. In addition, tourists and visitors to the area may not be enrolled in the system and therefore would not receive any alerts during evacuations. Several interview participants noted that having a system that pushes notifications out to any cell phones within the region would reach more of the community during hazard events.

Another communication challenge is the cell phone reception throughout the County. There are many areas with limited or no cell phone reception, including a portion of downtown Angels Camp.

This challenge can pose issues with communication, not only across responding agencies who are actively coordinating in the field, but also with residents and visitors who may need to receive alert notifications or hear from neighbors that they need to evacuate. Many people have gotten rid of their home phone lines, so cell phones are the main method of communication for community members.

Those who do have home phone lines may be impacted if the power goes out or these communication lines are damaged, and therefore prevent transmission of notifications.

Many of the stakeholders interviewed are aware of communications challenges and emphasized that connecting directly with community members is often the best way to provide information in a rapidly changing emergency event. Those who work for responding agencies often know where cell phone reception is spotty, or know particular areas where residents might not be receiving alert notifications. Responding agencies focus on going door-to-door or reaching out directly to community members in those locations to make sure they are evacuating, have a plan in place, or know where to go. However, as people who work for the responding agencies turn over, this learned information may be lost.

More visitors and seasonal residents have been coming to the area, especially as Covid has allowed more people to work from home. Several interview participants noted that many of these people are not necessarily prepared for the types of hazard events that happen in the region, especially when they have not experienced regular winter storms, fires, etc. Communicating with these new community members can pose a challenge, especially if they have not signed up for emergency alerts or if responding agencies are not as aware of where they are located.

6. Conclusions
Calaveras County experiences various types of hazard events, including wildfires, winter storms, mudslides, and flooding. The most recent major county-wide hazard event that had significant impacts on evacuation was the Butte Fire in 2015. However, there have been smaller events that did require evacuation in portions of the County in more recent years, such as the Airola, O’Reilly, and Salt Fires, recent winter storms, and flooding events especially in Angels Camp. Some of these events had challenges with evacuation or access, especially in areas with narrow roadways.

Climate Debrief Interview Summary Report
11 Various interview participants noted that emergency planning for hazard events has improved significantly since the Butte Fire. In 2015 during the Butte Fire, the County OES was not fully functioning yet, but this event also crossed jurisdictional boundaries, requiring significant coordination. Many lessons were learned during this event, especially as roadways became backed up during the evacuation.

Improvements have been made with planning, mutual aid agreements, and communication systems.

However, continued improvements to emergency planning will help as the community prepares for hazards in the future.

While the County has mapped evacuation routes, currently a formal evacuation plan does not exist.

Identifying problem areas for ingress and egress is a first step in planning for improved evacuations.

Many roadways throughout the County are narrow, older, are in poor condition, or have access constraints (e.g., gated subdivisions). Some of these aspects are difficult to change but can be taken into account when planning for evacuations. While major damages and threats to human safety were avoided in past hazard events, future planning will have to consider worst-case scenarios to adequately plan for events.

Regular maintenance of roadways and defensible space can help keep evacuations clear and potentially reduce the threats of hazards or post-event hazards. These efforts require resources and funding, which can be a challenge. Exploring grant opportunities or other programs to support roadway maintenance and improvements will be important to support these needs.

Hazard events require coordination from many different groups. In recent events, the County OES has helped provide organization, structure, and resources to respond to hazards. The County OES coordinates very closely with other County offices, the Sherriff’s Office, fire districts, City of Angels Camp staff, California Highway Patrol, Caltrans, and CAL FIRE. Mutual aid agreements support this coordination and allow for resources to be put into place quickly when an emergency event occurs. As noted by several interview participants, there are also some state resources that the County can leverage that historically have not been used in past events, such as mobile units, portable bridges, mapping capabilities, communication systems, and other resources available from Caltrans and utilities.

Additional training, planning exercises, and continued relationship building and communication between responding groups will be very important. Knowledge transfer will also be important to consider with any staff turnover across these responding agencies. Planning exercises or “mock events” will help responding agencies to identify any challenges or gaps that should be addressed before a major hazard occurs. These types of exercises can also be extremely useful for public education and training to help the community understand what to do in the case of an evacuation.

Communication with community members will always have challenges because of the dynamic, rapidly changing nature of hazard events, as well as the rural aspects of the County. Existing communication systems like Everbridge and Nixle provide a rapid notification alert that can help blast information out quickly. Continuing to develop more robust communication systems and improving coverage will support information sharing and alerting residents and visitors in the event of an emergency.

Regular communication and outreach can also support community awareness-building. Pre-planning education, training, and outreach will help residents and visitors understand how to evacuate, where to evacuate to, and potential problem areas. Various agencies do regular outreach and education for the community, and these efforts can continue to emphasize the importance of not only emergency planning, but also potential mitigation strategies (such as maintaining defensible space around homes). All of these efforts will be important to consider as hazard events evolve in the future.

Please describe any recent large-scale hazard events that required evacuation or had transportation access impacts which you have been responsible for responding to or been affected by in your professional role.
o Hazard type: Fire
o Date(s): 2020
o Geographic area impacted: Within city limits of Angels Camp o Assets impacted: 1 residence lost, not occupied, had some business damages o Approximate duration of impact: 1 day (fire contained within about 3-4 hours), but 1 week incident time
Nate: Within City of Angels Camp we have only had one recent incident that meets this criteria – a wildfire within the city limits; required evacuations but other events have not. The wildfire occurred in 2020 (about

1.5 years ago). We lost a single-family residence, luckily it was not occupied and was already in a deteriorated state when it burned. Other businesses and single-family residences had damages, maybe a vehicle or two. The fire was extinguished within a day, but the incident spanned over a week or so (mopping up, doing damage assessment, etc.). The cause of the fire was not determined – insufficient evidence to move forward.

John: That fire was known as the O’Reilly incident. It was within the WUI but more urban than anything else, and was an extremely fast moving fire. Because of its location and topography within the City, it presented significant threat to the City itself.

Nate: The fire was about less than 10 acres in size. There is a pocket of open land about 15 acres in size that sits in the middle of the community; fire consumed most of this open area (or more than half), but fortunate that it did not turn into a conflagration across houses and the community. Not a large extension of wildland beyond that point, but there was definitely the potential of it continuing house-to-house.

Event Preparation, Communication, and Coordination

1. If there was time to prepare for the event, what strategies were used in preparation for this event?
(N/A – response only)

2. What communication methods were used to notify people about how and when to evacuate?
o Were they informed where to evacuate to?
Nate: Some of the areas surrounding the incident did need to be evacuated, the majority of this happened by people going door-to-door knocking (officers and firemen).

John: We sent out an Everbridge evacuation message to 200+ contacts. People were not told a specific area to evacuate to, they were just told to leave the area. o Were there any challenges in communication?
John: The fire unfolded very quickly. It went from a small spot fire to a house being impacted within 3-4 minutes.
o How did people know when they could return to their homes/businesses? John: When we lift any evacuation notices, we rebroadcast through Everbridge after the event to the original set of contacts that we used. In addition to that, we use geofencing. If you are an Everbridge Climate Debrief Interview Summary Report
15 customer and have the Everbridge app, and say you’re from Kentucky but happen to be in Angels Camp when something like that happens, it will push a notification to your phone if you’re an Everbridge customer. Or if you live here locally and say your phone was off or you were out of the area, when you come back into that geofence it will push that notification out to you. We always make sure we follow up an evacuation notice with a ‘you can go home now’ follow-up message.

3. Was coordination with other agencies, groups, or jurisdictions necessary? If so, who? Nate: Red Cross was contacted, but not really used because no one was really displaced. Primary coordination was between the City and the County and their various departments, but also CHP and probably Caltrans.

John: Caltrans, CAL FIRE, City of Angels Camp, local fire districts.

Nate: Local fire districts were there - Copperopolis, Murphys, Altaville Melones, San Andreas.

John: Because we closed off a state highway, CHP and Caltrans were involved. Angels Camp is a small police department (10-12), so there was mutual aid from the Sherriff’s office, which meant that my office stood up an EOC and started putting those people into the same room. Fortunately our guys on the ground got out in front of the fire and got it stopped before we really got rolling like Nate said. American Red Cross was contacted, and they may have made it to the EOC but I don’t think they stood anything up because the fire got extinguished quickly.

Nate: Coordination between CAL FIRE was really good, they were able put some assets in place, like aircraft that we needed very quickly.

Event Evacuation and Access

4. When evacuation was required during an event, how well did the evacuation routes function?
Nate: Evacuation routes didn’t function all that well – we are an old mining community, so several of the residential streets are very narrow, they were originally built for horse and wagon. So trying to get responders in while trying to get residents out posed a challenge. There were some parked cars along those streets which made it harder. Had to shut down the highway, so there was a back-up there in turning vehicles around (like logging trucks or larger commercial vehicles). So that was a challenging in getting them to turn around. But once we got them out of the area, the routes seemed to function okay because it was a small event.

John: One of the problems that we foresaw (but didn’t encounter because we stopped the fire) was because of where the fire started, there was no real alternative route to 49 in that particular part, especially for large commercial vehicles that would not be able to traverse the smaller residential streets.

We were starting to see that swirl effect where people are going in circles around the incident just trying to get past it but they just couldn’t. So that is just a feature of that particular incident. On a broader scale, we have mapped evacuation routes but in my 3 years, I have never seen an evacuation plan. It is important to acknowledge that now that we don’t really have much of a plan. Part of that is we never know which direction the fire is coming from. Hope to have a more refined set of guidelines that will allow us to do some evacuation planning through this effort with Dewberry.

5. Were people informed about where to evacuate to?
o If to a central location, did the access points to that location become backed up? For how long/how far?
As noted above, people were not told where to evacuate to.

6. Were there any road conditions that impacted the use of evacuation routes? (e.g., unmaintained defensible space, narrow roadway widths, poor pavement condition) o If so, how were individuals re-routed?
As noted above, narrow roadway widths were the main challenge.

Nate: Large vehicles pretty much just had to park on the side of the road until we could open up the road so they could get through.

Climate Debrief Interview Summary Report
16 John: And that just accentuates the problem – you have log trucks stacked up and no one can get around them. It could have become a serious thing had we had an extended attack and mop-up, but the whole incident was 3-4 hours until we contained the fire. Highway was also shut down about 3-4 hours.

Nate: Back-up probably was no more than a mile long, probably more like 0.5 mile.

John: Once word got out that the highway was closed, people could re-route long before then and avoid the area, which a lot of folks did. The problem that we had was that there wasn’t really a way to do that right in the vicinity of the event.

Nate: Defensible space and pavement conditions were good. Parked cars were really the only problem.

7. Were there any post-event secondary hazards (e.g., standing burned trees, mudslides) that impacted evacuation or transportation routes?
o What impact did they have (e.g., detours, temporary closures)? Both: None.

8. Did most people evacuate using a personal vehicle or was transportation required/provided?
Both: No transportation was provided, all personal vehicles.

9. Were there any challenges in evacuating particular groups of people? (e.g., senior populations, those with mobility issues)
o If so, how were they evacuated (e.g., types of vehicles)? Nate: There was one residence where someone was disabled, luckily that person did not need to be evacuated. Planning was started on how to get that person to where they needed to be, but did not end up having to evacuate. It was a single person at a residence.

Lessons Learned

10. What do you see as the 3 biggest successes in preparing for and responding to this event?
Nate: Biggest success is that even though we haven’t trained on this and don’t have a really good plan, the agencies worked well together to make it happen in a short amount of time.

John: Agree, the amount of resources we were able to bring to bear made a significant impact. The interactions we were able to have with the community – within moments of us broadcasting the Everbridge alert, we followed that up with social media and traditional media releases that helped spread the word to folks who don’t normally use those channels on a regular basis. It’s the organic nature of social media that it is grassroots, so I think our communication was effective.

11. What do you see as the 3 biggest challenges in preparing for and responding to this event?
Nate: Being a rural city and county, the amount of people we have on duty on any daily basis, and they are spread out throughout the County, so getting them to the scene in a relatively quick time period is a challenge. Having the manpower to fulfill all of the necessary needs.

John: I would broaden that and say the number of resources is always a challenge. We routinely rely on each other for “routine” needs. In a perfect world that shouldn’t be happening, but it happens in our rural world on a daily basis.

Nate: Due to our old road infrastructure, the area does not support better roads in some of these areas.

It’s already built, but it was not built in the standards it needs to be for modern times; it is what we have to work with and that’s a challenge.
o How do you plan on addressing the challenges you’ve identified? Nate: We’ve talked about trying to help ourselves out by having an ordinance where residents would not be allowed to park alongside the street on some of the narrow streets, so that we can best utilize what’s there without these parked vehicles. I don’t see our staffing or assets getting better anytime soon, just because of funding.

12. Are there any ways that planning, training, or exercises could be improved for this type of event in the future?
Climate Debrief Interview Summary Report
17 Nate: This was a good event to open the eyes for those of the community as well as those at the City to show the need for planning and training for incidents like this on a regular basis. We can utilize what we saw and what we have been talking about for creating a plan. And it may not be in that specific area, but we can use that to start the discussion of – if we have an incident here, and we need to shut down the highway, we would immediately start to reroute people this direction, and we would plan for this area to be the evacuation center, etc. Those types of discussions.

John: The current construction of a good portion of our roads, especially in the City of Angels Camp, does not meet modern building standards, were built for horse-drawn carts. It’s also important to pay attention to vegetation management on the sides of the roads; this has an effect on our biggest threat of wildfire, but this also has an effect on our ability to move large pieces of emergency equipment around.

Nate: It emphasizes the need to get important information out as soon as possible and communicate to as many people as quickly as possible, as the event allows. For this event, we didn’t have much time. But if we had a flooding event where we knew we were going to receive a lot of rainfall, we could start pushing out more advanced information and have people thinking about a plan ahead of time, or having people leaving the area earlier.

13. Did COVID-19 have any impact on the event response? Can you share any lessons learned for managing future events given ongoing pandemic management issues? Nate: No not for this event.

Other Questions
Any other events of note?
John: The biggest two threats to the County are wildfire and extreme weather events; there is a transportation component to both of them. In our planning, I can foresee a need to have a Highway 4 plan in place for the upper Highway 4 corridor. Not only for wildfire, which is by far the most prevalent threat, but also for winter storms. Obviously, you can’t drive away from heat very well, but you can drive away from snow. The Highway 4 corridor is the area most affected by the top two threats that we face. Extreme weather is mostly for winter storm for transportation aspects. Heat is also a consideration for people, especially as people want to escape the heat, but they usually would go up the hill. But if you live up the hill and 75 is the normal and 105 is what it is, that’s a heat event for you as well.

Do winter storm events require evacuation?
John: It usually poses the opposite problem. People are often trapped in their homes, run out of fuel or food, and we may be unable to get to them in a timely manner or something inhibits the snow plow and we have to extract them to a safe location.

Are there aspects of the routes that make them difficult for access in those winter events? John: Highway 4 is difficult because it is a 2-lane highway; can fit 40,000 people down this road but it will take a long time, that’s an issue for mass evacuations (like if we had a big wildfire). On the flip side, limbs and power lines across the roadway affect our snow plowing ability. We start running into kinks like Caltrans berming the County roads, and so we have to go dig the County berm out from the snow plow blowing snow onto the roadway. And we have to deal with the lines and trees that are commonly down.

This last year was worse than the year before because drought weakened trees that we had near roadways, trees fell across the roadway, collected power lines, and then it’s difficult for us to get that plowed.

Have portions of those roads been closed during winter events? John: Yes, most of them.

Is it easy to re-route people?
John: No; while we are concerned with making sure residents are safe, have their medications, etc., people from the San Joaquin Valley come up in their Prius with their wire chains to play in the snow. In the last two winter cycles we’ve had, we noticed a great influx in the number of people visiting their vacation homes or secondary homes during the winter. We have heard numerous accounts of companies Climate Debrief Interview Summary Report
18 saying they will never go back to the office, will always be remote. So then people from the Bay Area may be moving into their vacation homes at 4,500 ft elevation, having never really been there in January or December when the snow falls, and were very poorly prepared from personal preparedness and a resiliency standpoint. It’s an anomaly that we don’t really know how to solve quite yet. They don’t have an understanding that 3-4 ft of snow is common, but they may be unaware since they were previously visiting in the summer.

Is there education or awareness building done about having the right cars/tires for winter? John: We do winter storm preparedness education. A feature of Everbridge is you can opt in to receive weather alerts, including winter storms. We try to get information out if there is a storm looming, encourage everyone to make sure they have enough fuel, food, and water to get through at least a 72- hour period. But a lot of the time what we’re finding is that 72-hour number is pretty short.

Any other considerations you want us to capture – any areas that pose particular issues for evacuation or transportation?
John: The upper Highway 4 corridor is really paramount to me; even as far back as the Butte Fire. In that fire, there was bumper-to-bumper traffic downslope from Ebbetts Pass to at least Angels Camp which lasted for hours - heard reports for as many as 3-4 hours to reverse that 30-40 miles. There is a ‘demon’ stoplight in Murphys that people attribute the back-up to, but I think it’s more that it’s capacity issues with getting people through basically one lane. It’s narrow and windy, so don’t think that we could do reverse flow, because we still have to have a way to get equipment up the hill. I don’t see contra flow working well. At some point, the only thing we could do to try to relieve that is try to attack it from two fronts – maybe through very early and timely evacuation notices through Everbridge system; and then at some point if you are up the slope, if you are east or north of that point, you get sent over the hill to Bear Valley.

But I don’t know how to determine that cutoff point – where that would be effective. Another concern is more people moving to the area, and what impact that will have on evacuations.

Nate: There is a need for an alternative route where Highway 49 goes over Angels Creek in the south end of the city. It is a two-lane bridge that is old, and if that is impacted in any way, the only alternative to leave the City is east or west to get south. It’s several tens of miles east or west before you can start going south. There is a need for additional road to go south in case that bridge is impacted by an event.

The bridge was refurbished in the 1920s or 1930s. Getting resources in or people out is a challenge if that bridge is impacted in any way. It would be pretty easy using Highway 4 to get on the other side of the creek, but there is not any way to get south once you are on the other side of the creek, except for going across that bridge.

We also have several subdivision problem areas. There is a subdivision called Greenhorn Creek that was added in the 1990s, and is adjacent to the older part of the City. Three emergency access roads that connect the subdivision to the City; highlight the need for those emergency access points to be upgraded to actual streets or roadways to increase evacuation routing and traffic flow. That is a subdivision of about 400 homes, with only one paved way in or out. Those emergency access points are gated, requires someone to go and physically open that gate to allow circulation. In a community that does not have much staffing to begin with, to break someone off of incident response to go open the gates would be a challenge. Stelte Park is another subdivision with one way in and one way out, another emergency access road that is not pave, is also gated.

John: Meadow Bar is like that too, right?
Nate: Yes. Forrest Meadows.

John: Pretty interesting to me, being new to the County, that in subdivisions there are a lot of roads that are not County-maintained, to the point of entire communities. It is hard for the HOA to maintain the roads alone, let alone the escape routes that hardly ever get used. Communities have responsibility for maintaining those roads.

Climate Debrief Interview Summary Report
19 On the community HOA roads, are they also responsible for plowing of those roads in winter events?
John: Yes.

What is the coverage of Everbridge system within the community? John: We devised a map overlay of our County by fire mapping standards, so we broke the County down into 2x2 mile squares. We are able to look at those and interact seamlessly with CAL FIRE. The downside is that it is essentially a homegrown GIS layer or story board, so the problem is it’s difficult to get shapes out of them. At some point we are hoping to migrate to a more cloud-based system like Zonehaven, so that we can have people in the field can look at it on whatever device they have, determine areas that need to be evacuated, and send that information to the EOC via the cloud. That is a feature we are looking to upgrade on the alert and warning side. As of this very moment, we have 21,062 individual contact points in our Everbridge system. The County population is 45,292 (as of the last Census).

20 B.2. Scott Hertzog, Copperopolis Fire Protection District Date: February 18, 2022, 1-2 pm PT
Participant: Scott Hertzog, Interim Fire Chief, Copperopolis Fire Protection District Background: Scott has been at the Copperopolis Fire District since 2013; was a paramedic and now interim fire chief. Background with CAL FIRE before that. Most experience has been in Copperopolis in southern portion of Calaveras County. Don’t venture out to due to tax measure restrictions. Small department with 2 fire stations. Area covers 1,400 square miles. Have homes, golf courses, lakefront property mixed in with the wildland environment, some vegetation comes right up to homes. Significant amount of homes in the WUI.

Hazard Events
Please describe any recent large-scale hazard events that required evacuation or had transportation access impacts which you have been responsible for responding to or been affected by in your professional role.
o Hazard type: Salt Fire
o Date(s): July/August 2020
o Geographic area impacted: Near Salt Springs Reservoir o Assets impacted: Homes impacted, but none lost
o Approximate duration of impact: Several days (fire under control within first 24-48 hours, containment took several days to a week)
Scott: It has been almost 2 years since the most significant fire in the district. Don’t get a lot of the weather events that happen elsewhere; the area is right at the 1,000 ft level so did not experience the “snowmaggedon” in recent winter event. Most recent event was a vegetation fire out in Salt Springs Reservoir, called the Salt Fire. It was on the border of the district, so had a challenge with getting resources there because it is 20 miles from nearest fire station. It is a one and a half lane road that is not well maintained where the fire occurred; caused access problems with ingress/egress. A lot of livestock in that area. Only two entrances into the fire. Had resources coming in from all over Calaveras and Tuolumne; eventually they did a strike team request from a more southern region to get anyone they could to come down to it. With these one and half lane roads you have issues with people trying to evacuate, also people trying to get into their homes to make sure everything is safe. No hydrants/zero water out there. No steady water source for rural fire departments.

No homes lost, maybe an outbuilding or two lost to the fire. But more of the problem was people who live in that area were waiting at the last minute to know if they had to evacuate, trying to get animals and livestock out as well. Few businesses out there, just a few wineries. Two wineries that were closed for the season so minimal workers out there.

Fire was controlled within the first 24-48 hours, but took several days to a week after to completely extinguish the fire. Within 48-72 hours, people were allowed to come back to their homes. Typically Sherriff’s office (or CHP, depending on where it is), they are monitoring roadblocks and they allow residents back in to that area.

Event Preparation, Communication, and Coordination

1. If there was time to prepare for the event, what strategies were used in preparation for this event?
N/A, not much time to prepare

2. What communication methods were used to notify people about how and when to evacuate?
Climate Debrief Interview Summary Report
21 Scott: At the fire department level, we do not have a reverse 911 system within Copperopolis Fire Protection District, but the Emergency Command Center (ECC) has the ability to talk to the Sheriff’s office to do the reverse 911, calling out to land lines. Not 100 percent sure that that is the direct path it takes, but our primary responsibility is life, so if we see homes or people in harm’s way, we notify them right away. If it’s something we can get into quicker and not need to evacuate, we can go right to fire’s edge.

So you don’t know until you are there. Most of the time the residents will have their own community-based notification where they often share information with each other – they may use Next Door, Facebook, cell phone chain, email, text, and may even ride from house to house on ATVs or horses to let their neighbors know. A bit like the old west in that sense, especially in that area. But for us in that initial dispatch, we can request through the ECC to start evacuations, especially when we get aircraft over the fire and we need to let people know to get out, so it is often an ongoing event with multiple people involved. o Were they informed where to evacuate to?
Scott: Generally the Sheriff’s office will tell people where to evacuate to (e.g., they may set up evacuation center in town square – depends on size and location of the fire). o Were there any challenges in communication?
Scott: I’m generally at the station while everyone is at the scene, just listening to everybody. We operate off a tactical channel and a command channel, so it can get cumbersome. The tactical channel is just meant for the troops on the ground working, and the command acts as the in-between for the command center and other resources, so you have two different channels going on. For evacuations, we would just say – we need evacuations ordered for X, Y, Z streets, and the ECC will confirm it, and then get support from Sheriff’s office. I don’t know how well that unfolded. There were probably only about 20 homes in that area, so can’t say for certain how that played out. But generally there are some folks that will stay at their property no matter what, and others will leave as soon as possible. There were more updates on social media quicker than I would get it from guys on the fire line, so that aspect of today’s technology is vastly faster than we can be.
o How did people know when they could return to their homes/businesses? Scott: When a major event happens the Sherriff’s office goes into unified command – each department has representation. Everyone comes together for morning briefings generally about plans for what’s going on; may say today we will open things back up to the public, so that will get disseminated there.

3. Was coordination with other agencies, groups, or jurisdictions necessary? If so, who? Scott: Every fire district in Calaveras had an engine present at one point or another (minus Ebbetts Pass). Outside agencies were brought in via CAL FIRE through the mutual aid agreement; brought in and rotated as shifts. I believe Amador County had some engines out there as well.

Event Evacuation and Access

4. When evacuation was required during an event, how well did the evacuation routes function?
Scott: I was not there for the evacuations, but there was only two ways in and out and roads are very narrow. It’s hard because fire is so dynamic and changing, you can develop a plan and implement it but within seconds that plan is gone. So having the versatility of multiple plans or evacuation routes in place would be the best option. I didn’t hear or see anything about issues of access because of roads being blocked or cars backed up on the roadway for that particular fire. In general, certain areas are tough, but you have to make it work.

5. Were people informed about where to evacuate to?
o If to a central location, did the access points to that location become backed up? For how long/how far?
N/A

6. Were there any road conditions that impacted the use of evacuation routes? (e.g., unmaintained defensible space, narrow roadway widths, poor pavement condition) o If so, how were individuals re-routed?
Scott: Pavement can be a problem, roads are very old out there and some of the roads are maintained by road committees, or the owners of the land out there, some are County-maintained. Like everything Climate Debrief Interview Summary Report
22 else in California, the roads aren’t the best and could definitely use some attention out there. They spray painted about every pothole for about 10 miles there.

7. Were there any post-event secondary hazards (e.g., standing burned trees, mudslides) that impacted evacuation or transportation routes?
o What impact did they have (e.g., detours, temporary closures)? Scott: It was so far off the main road, that it wouldn’t have affected the main roads. But maybe driveways or access roads there were some burned trees that had to be felled or dropped. I did not hear any reports of mudslides.

8. Did most people evacuate using a personal vehicle or was transportation required/provided?
Scott: Everyone evacuated on their own.

9. Were there any challenges in evacuating particular groups of people? (e.g., senior populations, those with mobility issues)
o If so, how were they evacuated (e.g., types of vehicles)? Scott: People who are physically disabled can be input into the system as needing help, but not necessary for anyone in the area of this event.

Lessons Learned

10. What do you see as the 3 biggest successes in preparing for and responding to this event?
Scott: Our mutual aid system in the County is effective; got resources going right away and updated as the fire progressed. Were even able to call in resources outside of the County; three different agencies in the state SRA. The dispatch was correct, resource orders were correct; dispatch and mutual aid plan worked seamlessly.

11. What do you see as the 3 biggest challenges in preparing for and responding to this event?
Scott: Location was the only real downside given the access issues; had this been closer to the main road rather than 10-12 miles off, it would have been a different outcome. Most of the resources came in from the north side, other entrance is on the south.
o How do you plan on addressing the challenges you’ve identified? Scott: No major challenges to address there.

12. Are there any ways that planning, training, or exercises could be improved for this type of event in the future?
Scott: Nothing really to do differently in that case. Only a handful of roads in that area so you can’t get too confused; rolling gas oak woodland area so it’s pretty apparent where things are.

13. Did COVID-19 have any impact on the event response? Can you share any lessons learned for managing future events given ongoing pandemic management issues? Scott: July/August 2020 was when event occurred. Because it was 100+ degrees, we had several people going down from heat exhaustion and fatigue, and because of Covid we were limited by how many people could be on duty at the time. Not sure how many people were out that day because of Covid, but it had indirect impacts.

Other Questions
Any particular areas that could pose problems within the area? Scott: Area off of Little John Road that accesses the golf course and Kiva that is a boat launch and recreation area; that is a dead end. If there was a rapidly moving fire towards it, there would be access egress challenges. It is a 2-lane paved road with no shoulder. A lot of one-way road within those streets.

Climate Debrief Interview Summary Report
23 Everything is a dead end, multiple courts. Were a fire to occur in that area, there could be several issues with evacuation. Only saving grace is it is farther from everything else so it would be 15 minutes for next truck to get in, 30-40 minutes for second wave of engines to come in. That is definitely a point that has been brought up in the past by residents here. The district supervisors were going to build a bridge out towards Knight’s Ferry with a land grant that fell through, so now residents in that corner are going to have a challenge getting out to the main road, but once on the main road they should be okay to get out safely (two lane paved road). But that is an area of concern.

Another place - Diamond XX, similarly has two ways in. It is 20 acre parcels with moderate to fair condition roads. So spread out, intermixed roadways with oak woodlands with 2-4 ft tall grass. It’s another access egress issue; get several fires out there a year. Luckily able to catch them before they grow to significance, biggest several years ago was a couple hundred acres.

Another one – Circle XX, near where Salt Fire was. And Bar XX. All one way in, with multiple homes on 20 acre parcels. Access to get there is 20-30 minutes, and once you’re there the roads get really narrow so with a fire engine you will be hard pressed to find a spot to switch off. And in those outside areas there are no hydrants out there, and the access gets really narrow. We’ve gotten really lucky in the past few years that we’ve been able to control and contain with the aircraft resources getting there quicker. But those three – Diamond, Circle, and Bar XX and the Kiva/Little John area are the ‘hot points’ you could say that could use some attention.

There is a bridge over Lake Tulloch that separates Tuolumne and Calaveras. I’d say 3-5 times a year we have a big rig tractor trailer that hits the bridge or abutment or guardrail, which can close bridge for several hours, down to one lane or both lanes. We’ve gotten lucky that there’s been no fire at the same time, because that’s the only exit route to Tuolumne County. Just past the bridge, we typically lose another tractor trailer – either logs or lumber – tip over probably once or twice a year on average. If that happened during a fire, no one could exit to 108, everyone would have to re-route down 4 up to 49.

Any other challenges?
Scott: See the value of defensible space – that’s what helps save peoples home. Did defensible space inspections in previous work – unfortunately people are seeing the impact of not having defensible space.

That makes our job easier to focus on the bigger picture rather than having to focus on one neighborhood. We don’t have the people, personnel, or equipment to dedicate to every area. Everyone needs to do their part. Hurdles: it’s expensive, labor intensive and some people just don’t have the means or are disabled, though there are some help programs out there. I will be meeting with stakeholders to do outreach to educate on how to be a fire safe community. This might include Lion’s Club, Red Hat ladies, HOAs, road committees.

Have not made contact with them yet, but we are planning to this summer. Getting the message out there is important so that when fires do occur, homes and people will be fine if they stay in their home, or have a plan on where/how to evacuate (no matter where fire is coming from) and backup plans.

Anything else you’d like to share?
Scott: It really comes down to the roads at the end of the day in my opinion – whether it’s public or private. It’s unfortunate, but we have to make do with what we have.

What outreach have you done with stakeholders on fire safe communities? Scott: I am new in my role, so haven’t done the outreach yet. But it is my plan to work on bringing the district more together. There are a lot of road committees here – it is their form of an HOA. So there is the Rocky Road committee, which is the Diamond XX folks; Black Creek HOA; Copper Cove HOA; Poker Flat HOA; Copper Valley, which encompasses town square and Saddle Creek Golf Course; Copper Meadows HOA; Calypso Bay HOA; Lion’s Club; and Red Hat. Those are the ones I’ve gathered on my list just through meeting and talking to people so far. Will start getting that going next month, before summer kicks off.

Climate Debrief Interview Summary Report
24 B.3. Scott Nanik, Calaveras County Schools, and Rebecca Callen, City of Angels Camp
Date: February 18, 2022, 2-3 pm PT
Participants: Scott Nanik, Calaveras County Superintendent of Schools and Rebecca Callen, City Administrator, City of Angels Camp Background: Scott oversees all of the schools, coordinate all of the emergency responses for the schools; conduit between OES and the schools. Rebecca has experience from all over the County; worked for Calaveras County through 2019, worked with CCWD until December, then came to City of Angels Camp just a few weeks ago.

Hazard Events
Please describe any recent large-scale hazard events that required evacuation or had transportation access impacts which you have been responsible for responding to or been affected by in your professional role.

Scott: Have been here all the way back to Butte Fire (occurred before John Osbourn’s position existed), have been through several floods and washouts, heavy winter storms; most recent event was Airola Fire this last summer.
o Hazard type: Airola Fire
o Date(s): August 2021
o Geographic area impacted: was burning in the river canyon o Assets impacted: schools
o Approximate duration of impact: almost 1 week
Scott: With the Airola Fire, had to decide if it came up the canyon, it would’ve been coming up the backside of some of our schools. Our transportation for the most part is down in Angels Camp. Decided to close schools rather than risk leaving them open. If the fire jumped the highway, there is no way to get buses up there to evacuate school sites. Typical for our area is one way in and one way out. That was something the local fire guys had not thought of (schools). Since OES was created, having schools on there has been an important piece. Fire lasted almost a week. (Note that Scott’s answers to specific questions below correspond with the Airola Fire).

Rebecca: In all of my roles, have been involved in any emergencies that occurred. But since I just started at the City, I talked to staff with what experiences they have had. But I live in the City so I have experience as a member of the public here. A lot of our City staff who are in response capacity are also still relatively new so have not had a lot of experience with any major issues. Except for our Fire Chief.

Our Fire Chief and Public Works Director have both experienced various emergencies that have happened here. Public Works focuses more on winter storms. City of Angels Camp is a historic city and has a lot of very aged infrastructure, very small roads not built for current construction requirements.

When winter storms do occur, it does create a lot of flooding and erosion issues. Angels Camp is very hilly, not a lot of flat space, especially in historic areas. It is very steep, homes are then built up on terraces, so erosion in those areas during a winter storm event can be pretty drastic. There is a creek that runs through the City of Angels, have had issues if flow is really high, we have had to have evacuations on a road called Birds Way. There is only one way into and out of Birds Way, so there have had to be evacuations back there. Even if evacuations don’t have to happen, those homes flood on the lower floors.

What we try to do if we know a major storm event is going to happen, we reach out to those residents to make sure they are prepared or that they cannot be there when the storm events do occur. We try to help make sure they can relocate somewhere else, maybe another family member, or will point them to any County temporary housing or shelter if those are set up.

Climate Debrief Interview Summary Report
25 There is a road called Finnigan Lane – runs along Angels Creek. If Angels Creek is overflowing, those areas will flood. There are two ways to get in and out, depending on where you are, but we are always mindful of that.

Wildfires: We had the Airola Fire, also the O’Reilly Fire in 2020 – that one required formal evacuation, we coordinated with the County OES and law enforcement. We used Calaveras Alert and Nixle. Evacuated 3 streets in our City. Have had 4 other moderate-sized wildfires from 2018 to present where we considered evacuations but didn’t have to.

We did implement a new weed abatement ordinance to work with property owners to make sure we have clearing, so that if there is a fire we have ability to not have as much property damage.

In all cases, whether flooding or fire, we do have an issue with emergency equipment access and evacuation routes. In the case of the O’Reilly Fire, it was going right down the middle of the City of Angels, so everyone went to the back roads to try to get out, and people could not get out of their driveways. Roads are single lane or single and a half; in addition, we cannot get a fire truck up in some of those areas, couldn’t get a dozer up in some of those areas. So things pop up anytime there is an evacuation or a major event. We really are restricted by egress/ingress, because there often really is only one way in and one way out. That is primarily in the older part of our city, west of Highway 49.

We also have Big Horn Mobile Park – can be an issue getting people out, because it is just one road that goes around, so it gets completely congested.

Another issue is on a lot of skinny streets, if homeowners have cars parked there, you cannot get a fire truck through.
(Note that Rebecca’s answers to specific questions below address various hazard events, including Airola and Butte Fires, as well as flooding events).

Event Preparation, Communication, and Coordination

1. If there was time to prepare for the event, what strategies were used in preparation for this event?
(N/A – response only for Airola Fire)

2. What communication methods were used to notify people about how and when to evacuate?
Scott: I communicate directly with the superintendents, and then they send out communications through their systems. For my own office, we use Remind as a connecting source for all employees. Everbridge system is primarily used through County government.

Rebecca: For flooding events when we do have evacuations, we do a lot of knocking on doors. A lot of people back there are tenants so could change, there is not a great way for us to always know who is living back there. So we generally just have to go knock on their doors to let them know. o Were they informed where to evacuate to?
Scott: They opened a couple of evacuation centers down the hill in Angels Camp. We use the Mark Twain Elementary School gym in Angels Camp for that. We start to point people there – if they chose to evacuate. There were some mandatory evacuations; the community does a pretty good job of absorbing people that need to evacuate, so it is more of our at-risk population (low income, couch surfers, temporary housing) that is at our shelters. They evacuated animals to our fairgrounds. o Were there any challenges in communication?
Scott: No, worked really well in the case of the Airola Fire.

Rebecca: We are also the utility for everyone for water and sewer. We have not leveraged that contact information in terms of outreach. Most outreach historically has been door-to-door and flyers. We’re not a huge city, but that does take time, so when you’re in an emergency situation, it’s hard to get information.

Climate Debrief Interview Summary Report
26 During the O’Reilly Fire, I heard about it at work when I was in San Andreas, and as an Angels Camp resident, I had to go to other people’s Facebook pages and reach out to people who work in the city myself to try to figure out what was going on, or what was the best way for me to get home, or if where I live was in any evacuation area. We do have a shortfall there; we need to figure out a better way of reaching out to our population.

Scott: When we have smaller incidents that are not County-wide, our Nixle Red Alert system does not geocache cell phones in use in the area. We’ve got a lot of tourists in the area, and we have no way to alert them if there is an emergency. We need a way to reach everyone’s cell phone in the area to get a message to them.

Rebecca: What we have found is that most people have dropped their home phone line and only have a cell phone. County OES did outreach over a month or two for people to enroll their cell phones, but it is up to the population to enroll. But if you are a tourist here, you aren’t going to go to our Everbridge to enroll your cell phone. So we need the technology to be able to grab everyone who is pinging off a tower around here and alert them. The two problems are the tourists and there are the people who dropped their home lines and so are no longer on the list. So if they haven’t enrolled, we don’t have any way of contacting them.

Rebecca: The County really controls Nixle and the Everbridge system – we don’t control that, so we have to rely on them. So it depends on who is in charge of the system for the type of collaboration that we get. o How did people know when they could return to their homes/businesses? Scott: Did almost daily updates with parents and students via email and phone system.

Rebecca: From my understanding, same people who let people know to evacuate will reach out and give them a call to let people know when to return. We are planning to revamp our website here at the City; we don’t’ have a Facebook page, so we are going to get that up and running. Planning to leverage more communication that route so that we can keep the population notified.

3. Was coordination with other agencies, groups, or jurisdictions necessary? If so, who? Scott: Public health was involved, because of need to manage that during Covid. American Red Cross took over the shelter – that created some challenges when it came to shutting it down. Some communication issues between County and Red Cross not getting the okay to shut down the facility, wouldn’t accept that directive from the County. Shelter ran for 3-4 days longer than it should have.

Are there challenges in coordinating with agencies when a hazard crosses boundaries? Rebecca: For the Butte Fire, absolutely. For the more recent emergencies, because we have had an OES at the County, that piece has gone a lot better. A lot more coordination because we learned from that event. As you have staff turnover in these respective jurisdictions, we need a way to continue to train and educate those newer people on how this all has to work. For the Butte Fire, that was the biggest downfall. They had all these things in place during Old Gulch Fire (in the 1990s), but between that and 2015, everyone at the County had turned over. There had been no training, and no one knew where the Emergency Operations Plan was, or if there even was one. It would be helpful for our OES to lead the charge and make sure that there is training available for all of the jurisdictions so that we in leadership know who we need to contact, who’s on first, etc.

Event Evacuation and Access

4. When evacuation was required during an event, how well did the evacuation routes function?
Scott: Evacuation in this case functioned well because we had time and the routes were open. If the highway gets blocked, it can get ugly, if it is a major event it overloads the highway completely.

Rebecca: If an evacuation is necessary, tourists often have no idea how to reroute in the area.

Generally what happens is we will ask for assistance from a mutual aid perspective (whoever we can get) to stage and direct traffic. The Butte Fire was tough because it was the entire County. So in Angels Camp it was just City fire and police, because the County was trying to evacuate other pieces of the County first.

Climate Debrief Interview Summary Report
27 At that time, we did not have mutual aid agreements with all of the entities during the Butte Fire – had to work on putting those together while the fire was still burning, but those pieces are in place now.

5. Were people informed about where to evacuate to?
o If to a central location, did the access points to that location become backed up? For how long/how far?
As noted above, there were some evacuation centers in Angels Camp and there were no issues with backups.

6. Were there any road conditions that impacted the use of evacuation routes? (e.g., unmaintained defensible space, narrow roadway widths, poor pavement condition) o If so, how were individuals re-routed?
Scott: No, there are narrow roads but it didn’t create any problems.

7. Were there any post-event secondary hazards (e.g., standing burned trees, mudslides) that impacted evacuation or transportation routes?
o What impact did they have (e.g., detours, temporary closures)? Scott: No, because most of the scar was on the water side of the reservoir.

8. Did most people evacuate using a personal vehicle or was transportation required/provided?
Scott: Mostly personal vehicles. We don’t have a robust transit system that can be activated. School buses are secondary after students are taken care of, no event where that’s been needed.

9. Were there any challenges in evacuating particular groups of people? (e.g., senior populations, those with mobility issues)
o If so, how were they evacuated (e.g., types of vehicles)? Scott: Mobility issues can be a big issue, but really not in designated areas, it is home by home. Have a very small ESL population in the County, so that’s not an issue.

Lessons Learned

10. What do you see as the 3 biggest successes in preparing for and responding to this event?
Scott: Nobody got hurt. It worked really well, it was not a huge event, which allowed us to work together and figure some things out on the communication pieces; team came together quickly.

11. What do you see as the 3 biggest challenges in preparing for and responding to this event?
o How do you plan on addressing the challenges you’ve identified? Scott: None that I can think of.

Rebecca: As a resident during the Airola Fire – I saw the flames and thought, I probably shouldn’t drive down that way, so I went a different way. But during the Butte Fire in 2015, that was horrid. We didn’t have a functioning OES really. The schools were frustrated because there was just a complete lack of communication.

Scott: We evacuated kids – took them home on school buses and dropped them in evacuation zones.

That’s how bad it was.

Rebecca: They bussed kids to the fairgrounds, and the fairgrounds were no longer an evacuation site, it was where all the emergency response people were at that point, so it was a total cluster. I know from working at the County, and from being a resident of the County and living in Angels Camp, no one knew what was going on. That fire – even though it started in Amador, no one thought it could get to Angels Camp. By the time I got to Angels Camp, we were trying to get people out of County offices, part of Angels Camp was evacuated. But I didn’t know that until I got home. So we’ve come a long way since 2015, but that was a real tough one. A lot of changes have been put into place because of that Butte Fire, but we still have some pretty significant gaps. And we are always contemplating the whole Climate Debrief Interview Summary Report
28 ingress/egress, especially in historic areas in our planning, to see if there are ways we can incorporate that hazard mitigation into potential grant opportunities that would help us identify grant funding so that we could expand different ingresses and egresses, but it’s been pretty challenging and hard to do that.

12. Are there any ways that planning, training, or exercises could be improved for this type of event in the future?
Scott: Not really training, it’s really just a communication issue, working with other agencies and schools just to coordinate because it’s all so fluid. We are going to still with our plan of having just one person communicate to the group from OES, seems to work smoothly. (See planning and training improvements noted by Rebecca above)

13. Did COVID-19 have any impact on the event response? Can you share any lessons learned for managing future events given ongoing pandemic management issues? Scott: Did not have a huge response to need for shelter, but that could have been a challenge. Shelter did have limitations on number of people and spacing considerations.

Other Questions
Any other particular problem areas?
Rebecca: Birds Way and Finnegan are the two streets that always have issues with flooding, because those are the two streets right on the creek. Other areas: Bush, Echo, and Crystal were heavily impacted with the O’Reilly Fire. Those are all in historic part of Angels Camp – all on steep slopes with very narrow roads. Those roads were right in the path of that fire. If we hadn’t got as quick assistance as we did with air support, it would have gone right through Angels Camp, would have been all through the historic streets. Once you get into the middle of downtown, you cannot get out.

Any challenges that need to be addressed as we look towards future hazard events? Scott: Emergency routes system are not communicated well and don’t know how well the public will respond to being told – don’t come down the hill and take a back road that is dirt to get out. I’m really concerned about how that plays out in a crisis. It’s a great system, and it’s probably our best alternatives, but how we communicate it is my biggest concern. We don’t have any way to monitor it to route people in that direction. We could not get people here fast enough during the Butte Fire; if we get another one of those, there’s no way. We’re just lucky that everyone on Highway 4 – that no one died, because it went across Highway 4, which was a parking lot. So we need to re-train our public.

Rebecca: Having a more robust communication system is really important. Benefit of being in the City is we don’t have cell reception issues – except some areas in downtown we have a few issues. So if you’re downtown, you might not get the call because there is a dead spot for cell phones in downtown. Unlike the rest of the County where there are whole swaths of dead spots across the county for cell phones.

Everyone who is not registered for the notification system or doesn’t have a home phone, we don’t have a great way of communicating with them.

Have there been any evacuation practice exercises?
Both – no.

Rebecca: That’s the missing piece with our OES. What I fear is if we don’t plug that hole and another Butte Fire happens, we will have the same problems. While there are some people who are around now during that fire, we might not be around for the next one. We need to train the next group, who may not have experienced the Butte Fire.

Other lessons?
Rebecca: The other thing during Butte Fire was we relied heavily on non-profits, church organizations, etc. (County-wide). There was an enormous amount of outreach and support, but it is still important that it needs to be managed. Very well intended people that showed up to volunteer, but there has to be a better mechanism in place to manage that response. Not just about training people in the schools and government, but also about training the public or volunteer groups who would support in an emergency.

Climate Debrief Interview Summary Report
29 B.4. Gregoria Ponce and Charly Modrell, Caltrans
Date: February 22, 2022, 8-9am PT
Participants:

Gregoria Ponce. Chief, Office of Rural Planning Caltrans District 10 Planning Charly Modrell, Mountain Region Manager, Caltrans District 10 Maintenance Background:
• Gregoria assists rural cities and counties in planning their infrastructure, implementing community visions, and applying for grants related to scenario planning, complete streets, and traditional planning components. Gregoria helped support the District 10 climate vulnerability assessment. • Charly Modrell oversees maintenance operations and is part of the emergency operations team for District 10.

Hazard Events
Please describe any recent large-scale hazard events that required evacuation or had transportation access impacts which you have been responsible for responding to or been affected by in your professional role.
o Hazard type: Winter storms, floods, mudslides and the Butte Fire o Date(s): Significant winter storm in 2017; Butte Fire 2015 o Geographic area impacted: Calaveras County and other areas in District 10 o Assets impacted: Road impacts for winter storms; extensive impacts from Butte Fire o Approximate duration of impact: Not specified
Charly: We have not had any serious events in the last few years, but we did have the Butte Fire in 2015.

We have had some flooding and mudslide activities. There were significant storm impacts in December of 2021, no major closures on our highways, and we were pretty much able to keep our ingress/egress open during that event.

There was a huge winter storm event in 2017, and a section of Highway 26 was closed down for a significant amount of time and we had to detour folks (shut down for over 30 days). We also worked to keep people informed and provide ingress/egress. When county roads have difficulty, they look towards Caltrans to keep roads open.

As far as the Butte Fire, we had Highway 26 shut down for a significant period and had to keep ingress and egress for emergency crews. Our role is to have those road closures in place and take the burden off of law enforcement or fire crew. We also have some responsibility if there is damage to roadway infrastructure and responding to immediate hazards, such as fallen trees.

Event Preparation, Communication, and Coordination

1. If there was time to prepare for the event, what strategies were used in preparation for this event?
Gregoria: Certain counties have local emergency preparedness plans and we, Caltrans, are asked to provide input as to our role, in their plans (response submitted prior to interview).

2. What communication methods were used to notify people about how and when to evacuate?
o Were they informed where to evacuate to?
o Were there any challenges in communication?
o How did people know when they could return to their homes/businesses? Climate Debrief Interview Summary Report
30 Charly: We rely on the Sheriff’s office/highway patrol for communication. We work a lot with the highway patrol. We provide traffic control that is requested. The only information we provide to public will be what’s passed on from the Sherriff’s Office or County emergency services. We re-share messages on social media, tweet, and use CMS (changeable message) signs.

3. Was coordination with other agencies, groups, or jurisdictions necessary? If so, who? Charly: We are very open with CAL FIRE and the other local gov staff as well. 2017 was a big year, same with the Butte Fire, so there were cooperators meetings where we had representation.

Event Evacuation and Access

4. When evacuation was required during an event, how well did the evacuation routes function?
Charly: 2017 was not a full evacuation situation, but the Butte Fire was. Previously folks have been rerouted up Highway 4, and the re-routing could have been better coordinated. We provide crew and detour, but we do not lead evacuation. We do have full emergency operation capability, but this is not necessarily recognized or realized by partners. Our EOC could provide maps, engineering technology, mobile unit, or a portable bridge. We have a lot of resources that could be utilized, but it is not always communicated well. We can do more than just traffic control.

Have practice events happened?
Charly: We do them occasionally, but since COVID, we have not really had one. We generally do this on an annual basis. This would be helpful for new staff as well and learning what everyone has in terms of resources and capabilities.

5. Were people informed about where to evacuate to?
o If to a central location, did the access points to that location become backed up? For how long/how far?
As noted above, Caltrans does not lead evacuation efforts.

6. Were there any road conditions that impacted the use of evacuation routes? (e.g., unmaintained defensible space, narrow roadway widths, poor pavement condition) o If so, how were individuals re-routed?
Charly: There were other smaller scale slides and flooding areas due to weather conditions. There are not many alternatives, and that is always a challenge in these rural communities. There is not a lot you can do, but communication is important. Power outages, limited cell service, also create communication challenges.

7. Were there any post-event secondary hazards (e.g., standing burned trees, mudslides) that impacted evacuation or transportation routes?
o What impact did they have (e.g., detours, temporary closures)? See Question 11 response.

8. Did most people evacuate using a personal vehicle or was transportation required/provided?
(N/A)

9. Were there any challenges in evacuating particular groups of people? (e.g., senior populations, those with mobility issues)
o If so, how were they evacuated (e.g., types of vehicles)? (N/A)
Climate Debrief Interview Summary Report
31 Lessons Learned

10. What do you see as the 3 biggest successes in preparing for and responding to this event?
Charly: For the 2017 winter storm event, the response was quick. It was really impressive how quickly we got an emergency contractor out there to start repairs, how quickly we got the road shutdown, and got signs in place. The teams did a great job on instant response.

11. What do you see as the 3 biggest challenges in preparing for and responding to this event?
Charly: We did have a secondary incident. Having a little more foresight to focus on the larger picture of other potential hazards outside of the direct impact area would have been helpful. The secondary incident was another mudslide up the road and someone was stuck. No one was injured, but having a person trapped in between was hard.
o How do you plan on addressing the challenges you’ve identified? Charly: Relationship building is super important because Counties may not recognize the capabilities we have. Caltrans can be an afterthought after decisions are made. Law enforcement can communicate via radio, but we do not have the same capability on the radio network. Something to work on would be a better line of communication between us and first responders.

12. Are there any ways that planning, training, or exercises could be improved for this type of event in the future?
Gregoria: Include Caltrans in field training/simulation with other emergency responders. This would include communication, and also finding where are the ‘dead comm zones’ as this would reduce communication coverage (response submitted prior to interview).

13. Did COVID-19 have any impact on the event response? Can you share any lessons learned for managing future events given ongoing pandemic management issues? Charly: With the December storms, there were challenges with heavy snows and trees coming down. We were short staffed because of COVID effects. Our goal is to provide 24-7 coverage, but we were a little light on staff, and this affected our ability to respond directly.

Other Questions
Did you have any involvement with the 2020 O’Reilly Fire response? Charly: We were involved very minimally, I found out about it through a personal call that the highway was shut down. We were able to provide support, but direct communication about the highway shutdown did not happen.

Do you have general suggestions or thoughts on how evacuation could be done better for Calaveras County?
Charly: We do dam exercises with local dams, so we know what the emergency actions plans are for all of them. We do not have a copy of Calaveras County plan and that would help us. We are working with another county on an exercise currently, and we are more than willing to provide support and help.

Do you have thoughts on how to keep potential climate change impacts in mind as we are looking at evacuation and transportation needs for Calaveras County? Gregoria: I think there is some information about priorities from the vulnerability assessment that may help inform this, and I’d like to think more about this.

With regards to emergency preparedness plans, we can think beyond Caltrans, and ask how is Calaveras coordinating with their neighbors? Emergencies don’t have boundaries. Also, how can dead comm zones be evaded? Dead comm zones are when you look geographically, there are communication dead zones where this is no coverage. The tower could not be picking up. How can that be bridged? What can be done? In the times when it matters, it is often too late.

Climate Debrief Interview Summary Report
32 Also consider doing an inventory of what is Calaveras doing for a community emergency response team? What capacity does Calaveras have in terms of organizational citizenry? Additional Notes
Gregoria: Please reach out to GIS staff (Austin) for available vulnerability assessment data layers.

1. Introduction

1.1 Background
The Calaveras Council of Governments (CCOG) was awarded a California Department of Transportation’s (Caltrans) Sustainable TransportationPlanning Grant in response to Senate Bill 1 (SB 1), the Road Repair and Accountability Act of 2017. The SB 1 grant funding is intended to support and implement Regional Transportation Plan (RTP) Sustainable Communities Strategies (SCS).

Because wildfires in the west are moving faster, growing larger, and behaving with unprecedented fire activity, the CCOG and many rural northern California communities recognize the investments in evacuation route resiliency and function is a cost-effective tool in wildfire response. Calaveras County experienced this modern style of fire activity with the Butte Fire in 2015 and learned how inadequate existing evacuation routes were.

The CCOG has also participated in an Extreme Weather and Natural Disaster Prevention and Response Strategies Needs Assessment Program with funding provided by Caltrans's Adaptation Planning Grant program. The Assessment Program developed response strategies and recommended actions to mitigate potential natural disaster risks (primarily wildfire) within Amador and Calaveras counties. In response to the plan the CCOG needs information for these key actions:
• Understand the evacuation routes that serve several high-risk communities and identify potential ingress / egress impairments that may impact use of these routes during emergencies.

These impairments include unmaintained defensible space, narrow roadway widths, and poor pavement condition.
• Identify and document structural and vegetation related issues that impair evacuation routes along roadsides, roadways and shoulder widths and roadway turnouts and identify opportunities for vegetation management / expansion of defensible space along evacuation routes.
• Examine how climate vulnerability may impact roadside drainage ditches and drainage undercrossings (culverts, bridges). Of these, the most critical need is the maintenance of defensible space along roadway evacuation routes.
• Create a forum for resiliency stakeholders to conduct annual or biannual meetings to advance the discussion of improving the road network for extreme weather events. This forum can be used to coordinate emergency preparedness, resiliency planning and implementation efforts.

Stakeholder discussions of what is, and is not, working, create mutual efficiencies for pursuing grants, prioritizingresiliency projects, and engaging in public outreach and participation efforts.
• Share community training materials to educate residents about the importance of defensible space, preparing for an evacuation, and knowing where to get information in the event of an evacuation.

Evacuations may necessitate the relocation of the affected population to other parts of a locality, to adjacent localities, to another part of the state. The evacuation of large numbers of people from vulnerable areas will stress the capabilities of road networks, potentially increasing the time necessary to evacuate the threatened risk area. Re-entry to the area post-event is also a critical component requiring an assessment of the road-network, debris remaining in the area, and critical facility operational status and capacity. CCOG seeks to improve the ability of their service area to respond to evacuation needs and plan for the safereturn of their communities.

1.2 Project Overview
To help address County emergency and evacuation planning needs, the CCOG has launched a new project called the Evacuation and Access Needs Assessment and Preparedness Plan (hereafter called the project). The goal of the project is to build resiliency in the Calaveras County transportation system from the impacts of wildfire, extreme weather, and other events, which are exacerbated by climate

CALAVERAS COUNTY EXISTING CONDITIONS INTERIM REPORT

change. The project is developing a plan to facilitate adequate and sustained access to and from high-risk communities in Calaveras County, including the City of Angels Camp, during and after catastrophic events. The focus is on assessing the transportation network’s demands, capacities, and deficiencies or needs in responding, recovering, and adapting to catastrophic events. The project is evaluating the potential for wildfires and extreme events to impact the communities and infrastructure at the highest risk.

The project is proceeding in four progressive tasks: an existing conditions assessment, an analysis of hazard risk and vulnerability, an advisory and public outreach campaign, and the development of a final plan. This report presents results from the desktop research component of the existing conditions assessment.

1.3 Existing Conditions Report Overview
This Existing Conditions Report was prepared as part of the overall existing conditions assessment under Task 1 of the project. Data was gathered on existing County conditions, assets, and community characteristics, with a focus on identifying opportunities and constraints, incorporating prior planning and data development efforts, and learning from past extreme weather events. The assessment included:
• Collection and review of emergency plans and hazard mitigation documents, including the draft 2021 Multi-Jurisdictional Hazard Mitigation Plan (MJHMP) under development by Calaveras County Office of Emergency Services;
• Identification and mapping of locations and characteristics of roadway assets and transportation network, such as roadway classification and use;
• Identification and mapping of planned land use developments and population characteristics, including disadvantaged community status;
• Identification of climate change projections expected to impact the transportation network, such as precipitation, temperature, wildfire, and dam failure;
• Identification and review of additional case studies, reports, and reference documents.

The remainder of this report is organized into seven sections that overview information that was gathered on the existing Calaveras County conditions. Each section contains language from the MJHMP and other relevant reports. These reports and other sources contain much more detailed information that will inform the next step in the project, which is an analysis of hazard risk and vulnerability. The topics covered in the seven sections are:
• Section 2 - Environment: geography, natural resources, hydrology, and land use. • Section 3 – Boundaries: major political and natural borders. • Section 4 – Communities: demographics and vulnerable populations. • Section 5 – Infrastructure: roads, buildings, and other infrastructure. • Section 6 – Natural Hazards: risk profile due to hazards that impact evacuation. • Section 7 – Climate Change: projected changes to local climate and impacts on evacuation. • Section 8 – Emergency Planning Documents: government emergency and hazard mitigation planning documents.

Appendix A contains maps of existing conditions throughout the County.

1.4 Companion Databases
As a supplement to the Existing Conditions Report, there are two companion databases that archive the most pertinent information that was reviewed for the existing conditions assessment. They are described in Appendix B and Appendix C, respectively, and briefly summarized below.

2. Environment

2.1 Geography
Calaveras County is situated in the central Sierra foothills between Yosemite National Park to the east, Lake Tahoe to the northeast, Sacramento to the northwest, and Stockton to the west (see Figure 1 in Appendix A). It is bordered by several lakes and reservoirs, including New Melones Lake to the south, and Camanche and Pardee reservoirs to the north. Mountainous terrains to the east and central parts of the County slope down to valleys in the west.

The County covers 1,037 square miles, or 663,478 acres, and includes the 3.6-square miles incorporated City of Angels Camp as well as multiple unincorporated communities: Arnold, Avery, Burson, Copperopolis, Dorrington, Douglas Flat, Glencoe, Forest Meadows, Mokelumne Hill, Mountain Ranch, Murphys, Paloma, Rail Road Flat, Rancho Calaveras, San Andreas, Sheep Ranch, Tamarack, Vallecito, Valley Springs, Wallace, West Point, and Wilseyville. Calaveras County is considered part of the Gold Country and High Sierra Regions of California. Together with neighboring foothill counties, Calaveras County forms a central part of the Mother Lode Region, an area with remarkably rich mineral deposits, including gold, asbestos, chromite, clay, copper, zinc, limestone, quartz, and tungsten. The unique limestone geology of Calaveras County as part of the “Calaveras Formation” has resulted in the formation of a significant number of caverns throughout the County. These caverns range in size from small openings only a few feet in extent to deep caverns hundreds of feet in length and depth that consist of numerous passageways and rooms that host marvelous formations. The limestone formations also contribute to the formation of sinkholes.

2.2 Natural Resources
Calaveras County has a variety of natural resource assets that to a large extent serve as the basis for the County’s economy and quality of life. These assets include water, critical species, wildlife and plant habitat.
• Non-Native Annual Grasslands – Grasslands provide food for livestock; habitat for birds, squirrels, hares, rabbits, voles mice, raptors, and hawks. Coyote, red fox, striped skunk, and Virginia opossum are also present.
• Chaparral – Chaparral is a one- to two-layer thick layer of drought-adapted, evergreen shrubs that are 6 to 13 feet tall. These shrubs often form dense thickets that can shade out herbaceous species. If a herbaceous understory is present, it varies seasonally and annually. The chaparral layer is fire-adapted. It is home to many wildlife species. • Conifer Forests – Several different types of coniferous trees are present in the County and can be sub-divided according to elevation into upper and lower montane mixed coniferous forest.

The lower montane forests are commonly referred to as Sierra mixed-conifer forests and include ponderosa pine, black oak, cedar, Douglas fir, canyon live oak, and giant sequoia. There is one grove of giant sequoia in the North Calaveras Grove in the Calaveras Big Trees State Park. The upper montane consists of forests, meadows, aspen, chaparral, and non-forested rock outcrops and provides habitat for a variety of wildlife. Upper montane coniferous trees include red fir, lodgepole pine, and Jeffrey pine.
• Hardwood Forests – Hardwood forests consist of evergreen trees such as evergreen oaks, and madronoe and broad-leaved deciduous trees.
• Seasonal Wetlands – Seasonal wetlands are located throughout the County and provide important functions including groundwater recharge, pollutant filtration, and aquatic habitat and water source for a variety of wildlife species.

2.3 Hydrology
According to the U.S. Geological Survey (USGS), California has 10 hydrologic regions. Calaveras County sits in the San Joaquin hydrologic region, which encompasses the middle portion of the Central Valley bounded by the Sierra Nevada Mountains, the Coast Range, the divide between the American and

CALAVERAS COUNTY EXISTING CONDITIONS INTERIM REPORT
E N V I R O N M E N T 8
Cosumnes river watersheds, and the divide between the San Joaquin and Kings River watersheds. The region also includes portions of the Sacramento-San Joaquin Delta. Although predominantly agricultural, this region has experienced increased urbanization in recent years and is subject to flooding from winter storm events and snowmelt.

2.4 Waterways and Watersheds
Calaveras County contains three major rivers – Mokelumne, Calaveras, and Stanislaus. The rivers carry runoff from the western slopes of the Sierra Nevada westward across Calaveras County, and into the Central Valley. All three rivers are dammed at one or more locations. The lower stretches of the rivers provide irrigation water for valley agriculture and are used for municipal water supply within the County and the surrounding areas. The seven primary watersheds in the County are:
• North Valley Floor
• Middle Sierra
• Upper Calaveras
• Stanislaus River
• San Joaquin Valley Floor
• Gopher Ridge
• Lower Calaveras
In addition to the three major rivers, there are a number of perennial and seasonal creeks throughout Calaveras County (see rivers map in Figure 4 in Appendix A).

2.5 Land Use
Calaveras County consists of a number of small, historic communities established primarily during the Gold Rush period of early California history, separated by large landholdings of agricultural land (primarily used for grazing) and timberland, interspersed with rural residential homes on larger acreage lots of five to twenty acres or more. There are several active and inactive mines in the County along with the recreational resources of several reservoirs, Stanislaus National Forest lands, and Calaveras Big Trees State Park. More recently, more than 20 boutique wineries have been established in the area around Murphys. Approximately 21 percent of the land in the County is publicly owned.

Calaveras County’s communities lie primarily along the historic routes of Highways 49 and 12. These include Mokelumne Hill, San Andreas, Valley Springs, and the incorporated city of Angels Camp. State Route 4 is the only trans-Sierra route in the County; Copperopolis, Murphys, and Arnold lie along this route. Other smaller communities include Wallace and Burson in the western end of the County, West Point, Wilseyville, and Mountain Ranch in the north-central part, and Avery and Dorrington on Highway 4.

Calaveras County has historically relied on industries such as timber production, mining, and agriculture for its economy. The historic communities that have grown up around these industries have been the centers of commerce and population for much of the County’s history. In more recent decades, beginning in the 1960s and 1970s, manufacturing and resource-based jobs began to decline when the cement plant in San Andreas closed and the timber industry contracted. The economy has shifted in the past several decades to rely more on tourism and service industries, and residential home construction. New residential subdivisions were built near Valley Springs, Copperopolis and along the Highway 4 corridor between the 1970s and 2008 to accommodate growth within the County, which at that time was about

4.8%. The 1996 General Plan land use map designated large areas of land for future residential development throughout western and central parts of the County. However, when an economic crisis struck in 2007-2008, population growth was stagnant and started to decline, pausing new residential construction, which has remained stagnant since that time.

CALAVERAS COUNTY EXISTING CONDITIONS INTERIM REPORT
E N V I R O N M E N T 9
Future land use and growth management strategies in Calaveras County aim to concentrate future development into and toward existing communities away from locations where natural characteristics may limit development (e.g., steep slopes or sensitive habitats), and to areas that have, or can readily be supplied with, adequate public facilities and services. This is done through various policies relating to zoning and minimum development standards and requirements. Zoning designations prescribe allowed land uses and minimum lot sizes for the purpose of supporting efficient infrastructure design, conservation of natural resources, and to avoid conflicting uses.

Existing land use is summarized in the table below.

3. Boundaries
Calaveras County has been subdivided according to a multitude of natural, political, and administrative boundaries. Many of these boundaries need to be taken into account in the development of County evacuations and emergency preparedness plans. Table 2 describes some of the major County boundaries, which are all included in the supplemental Geospatial Database (see Appendix B).

4. Communities

4.1 Demographics
Calaveras County is home to approximately 45,600 people, and the City of Angels Camp is home to another 4,020 people. The overall population density is about 40 people per square mile. The table below provides selected demographic information.

Table 3. Calaveras County selected demographics.

4.2 Vulnerable Communities
According to the FEMA National Risk Index for Natural Hazards, the social vulnerability index varies from relatively low to relatively high across the County’s ten 2010 census tracts.1 The census tracts along the southwest border, closer to the Pacific coast, tend to have a lower social vulnerability, while the tracts in the eastern mountainous terrain tend to have higher social vulnerability. The tracts containing the City of Angels Camp also have relatively high social vulnerability.

According to the definition of low-income communities developed for Assembly Bill 1550, most of the County that is north of the Golden Chain Highway (SR 49) are low income communities. Low-income areas are defined as census tracts that are at or below 80 percent of the statewide median income, or at or below the threshold designated as low-income by the California Department of Housing and Community Development.2 According to the definition and maps developed for Senate Bill 535, there are no disadvantaged communities in Calaveras County.3

5. Infrastructure

5.1 Transportation Assets

5.1.1 Roads
The County is served by four state highways and numerous secondary roads (see Figure 2 in Appendix A). State Highway 49 is the main north-south route through the County. It meanders through the foothills and extends from Mokelumne Hill in the north through Angels Camp to Melones in the south. State Highway 4 is another major east-west route that runs through the eastern and southern parts of the County. It runs from Bear Valley just east of the County toward the southwest through Angels Camp to Copperopolis and then out of the County toward Stockton. Sixty-one miles of this highway, starting in Arnold and extending into the high Sierras, has been designated a National Scenic Byway by the U.S. Department of Transportation. State Highway 26 is a major eastwest route through the northern part of the County. It runs from West Point in the northeast toward the southwest through Valley Springs and Scenic Valley Ranchos. State Highway 12 runs east-west in the northwestern part of the County. It extends eastward from Wallace in the west toward Valley Springs, where it connects with Highway 26.

5.1.2 Airports
Calaveras County is well served by air as well as roads. Fifty airports/ heliports of various sizes and capacities are within fifty miles of Angels Camp. Calaveras County operates its own General Aviation Airport, Calaveras County Airport/Maury Rasmussen Field. It has hangars, tie downs, and aircraft maintenance services. It is located between San Andreas and Angels Camp at an elevation of 1,325 feet.

The runway is 3,600 feet long and will accommodate 95% of general aviation aircraft. Columbia Airport (COA) in Columbia and Westover Field Airport (JAQ) in Jackson are two other General Aviation Airports in the area. Columbia Airport, fourteen miles south of Angels Camp, is located within walking distance of the historic town of Columbia in the Sierra Nevada foothills. It sits at an elevation of 2,118 feet and has a lighted 4,650-foot paved runway and a 2,600 foot irrigated turf runway. The Westover Field (Amador County Airport) is located approximately 15 miles northwest of Calaveras County in Jackson. It is at an elevation of 1,690 feet and has a runway that is 3,400 feet long.

5.1.3 Buses

5.1.3.1 School Buses
Calaveras County is home to four school districts plus Calaveras River Academy, Mountain Oaks Charter School, and Building Bridges preschool that have a total of 19 schools that serve approximately 5,300 students.

Additional bus service is available on-demand with some restrictions on days for certain parts of the County. The current bus schedule is available at the Calaveras Connect website at http://calaverasconnect.org/.

5.2 Critical Facilities
The 2021 Calaveras County Multi-Jurisdictional Hazard Mitigation Plan (MJHMP) adopts FEMA’s definition of critical facility and categorizes its facilities accordingly: Essential Facilities, High Potential Loss Facilities, and Transportation and Lifelines.4 The following are general categories of critical facilities in Calaveras County. The MJHMP describes the number and location of each.

6. Natural Hazards
The 2021 MJHMP provides a comprehensive review of natural hazards across Calaveras County. The analysis used three criteria – extent, probability, and risk rating – to fully understand the potential impacts of these hazards in Calaveras County. Hazard extent refers to the potential severity of a disaster and any secondary events caused by the hazard in the County, and is designated as either catastrophic, critical, limited, or negligible. Hazard probability is the expected frequency of future events, and is designated as either highly likely, likely, occasional, or unlikely.

As part of the development of the 2021 MJHMP, planning and steering committee members were asked to score each hazard using the probability classifications and extent of damage to come up with a score which varies from low to high risk. Table 6 summarizes the extent, probability of future occurrences, and risk ranking for eight hazards that may trigger an evacuation: dam failure, debris flow (landside, mud flow, or avalanche), earthquake, flooding, volcano, or wildfire. Wildfire is the highest risk hazard across Calaveras County with a High Risk ranking. Debris flow and flooding are the next highest risk hazard with a Serious Risk ranking. Dam failure, earthquake, and volcano hazards are Moderate to Low risk ranking.

The hazards are summarized using language and information from the 2021 MJHMP in the sections below.

Wildfire Catastrophic Highly Likely High

6.1 Wildfire (High Risk)
Wildfires are an ongoing threat for Calaveras County. The fire season usually runs from early spring to late fall, but this is rapidly changing because of recent droughts and dry conditions. Wildfires in Calaveras County are now possible almost year-round. Fires generally ignite due to some combination of hot weather, an accumulation of vegetation, low moisture content in the air, and anthropogenic activities.

These factors, in addition to high winds and drought, increase the chances of wildfire.

Several conditions within the County make it susceptible to wildfires such as its low-lying foothills to the south and west, and in the mountainous areas to the north and east, the terrain and topography are such that fires can spread quickly upslope and suppression equipment is limited. In the brush fields in the central portions of the County, summer temperatures can be very hot and this in combination with winds, and different fuel types (e.g., brush, timber, ladder, ground) can make the perfect wildfire conditions. On the CalFire Fire Hazard Severity Scale, which uses three criteria to assess risk – fuel loading vegetation, fire weather (winds, temperatures, humidity levels, moisture content), and topography (degree of slope) – at least 85 percent of the County is an area of high or very high wildfire severity (see Figure 3 in Appendix A).

CALAVERAS COUNTY EXISTING CONDITIONS INTERIM REPORT
N A T U R A L H A Z A R D S 15
The County has a long history of wildfires and potential losses can be very devastating, impacting everything from human life, structures, power lines, and water supplies. Wildfire smoke and haze can also degrade air quality and breathing conditions for at-risk populations. In the natural environment, wildfires can have long-lasting effects through vegetation loss, soil erosion, increasing sedimentation, and reduced natural water storage capacity. The extent of wildfire damage in the County is rated as catastrophic, with more than 50 percent affected and the probability of a wildfire occurring is highly likely. In the National Fire Plan produced by CalFire, all of the major communities in the County were identified as at risk for wildfire based on fuel hazards, probability of fire, and areas of suitable housing density that could create wildland urban interface fire protection strategy situations. Because rural residential development is increasing, more property and people are at risk – approximately 45,000 people in the planning area and the unincorporated areas of the County may be impacted by a wildfire.

6.2 Debris Flow (Serious Risk)
Debris flows are geological phenomena in which water-laden masses of soil and fragmented rock rush down mountainsides. In Calaveras County, there are three basic types of hazardous debris flow:
landslides (including rockslides), mud flows, and avalanches. The risk from each is discussed below.

6.2.1 Landslide
A landslide is the breaking away and gravity-driven downward movement of hill slope materials, which can travel at various speeds. In Calaveras County, landslides occur most often on steep slopes in the mountainous eastern part of the County. The 2021 MJHMP assesses the extent of a landslides in Calaveras County as critical and its probability as likely. Approximately 2 percent of the land area of Calaveras County has soil types that are highly susceptible to landslides, and the USGS has developed County-wide maps of landslide vulnerability. Specifically, locations near Jenny Lind and Ebbetts Pass are at greatest risk from landslides. Also, the western edge of New Hogan Reservoir and southwest of Ebbetts Pass have significant areas of soils classified as having severe erosion potential. Landslides in these mountainous areas with high elevations and steep ravines could block major roads and therefore limit access to emergency vehicles. In recent years, the County has had several damaging landslides. In 2015, a heavy rainstorm and high mountain snow in the burned areas from Butte Fire caused over $10,000 in property damage from debris and mud flows. In 2016, heavy rains on State Highway 26 between Mokelumne Hill and Glencoe (within the Butte Fire area), caused over $5,000 in property damage from debris flows. Storms in February 2019 caused a landslide that closed three miles of State Highway 26 for 69 days and cost $3.5 million in repairs.

6.2.2 Mud Flow
A mud flow is a broad term for a mass-movement process characterized by a flowing mass of fine-grained earth material with a high degree of fluidity. Across Calaveras County, mud flows tend to occur on steep slopes in the mountains and can occur without warning. Unlike landslides, mud flows have the potential to impact life and property on a much larger scale. A mud flow can block roads, take down power lines, move buildings off their foundations, and cause injury and death to persons caught in the path. The impact of a mud flow event depends on the amount of land moved, the amount of infrastructure and people present, and the volume of water in an affected waterway. Areas located at the base of stream alluvial fans have extreme susceptibility to flows, as do areas where mud and debris can be channeled such as downslope roads and waterways. This includes any of the major County roads where a flow could wash out a portion of the road or sitting vehicles, making rescue efforts difficult.

Due to their widespread area of occurrence, the extent of a mud flows in Calaveras County is rated as critical and its probability as likely. Several large and disastrous mudslides have occurred in the County, such as the January 1997 event. The slide started near Highway 4 and Cottage Springs as the result of a storm and slid one and a half miles into the Stanislaus River, taking out roads, a bridge, and Forest Service facilities. It is estimated a total of one million cubic yards of mud came down. In 2015, heavy rain and snow in burned areas from the Butte Fire caused road closures and overtopped bridges, totaling over $10,000 in property damage.

N A T U R A L H A Z A R D S 16

6.2.3 Avalanche
An avalanche is a rapid flow of snow down a hill or mountain. Snow can fracture at any point on a slope, but it typically starts higher up on slopes and an avalanche run can take out everything in its path. Several factors affect the likelihood of an avalanche occurring including weather, temperature, slope steepness and orientation, terrain, vegetation, and snowpack conditions. Historically, avalanches occur in California between December and March, but climate change may exaggerate this hazard as events may occur outside this window and weather patterns of heavy snowfalls followed by thawing may increase the likelihood of an event.

Due to its small area of occurrence, the extent of an avalanche in Calaveras County is rated as limited and its probability of occurring as unlikely. The northeast section of the County is most prone to avalanches near Bear Valley in Alpine County along State Highway 4. Avalanches can bury buildings and people in the runout zone, the area where the falling snow and debris finally come to a stop and pile the highest. These events can also bury County roads and vehicles and significantly impact the response time of first responders. The 2021 MJHMP notes that there have been no recorded avalanches to date in Calaveras County. Smaller avalanches do occur in the backcountry areas of the County with no affects and only one avalanche near Lake Tahoe which is outside the County boundaries, was recorded.

6.3 Flooding (Serious Risk)
Flooding results from the rising and overflowing of a body of water onto normally dry land. Calaveras County experiences different types of flooding events: riverine, flash, and stormwater. Riverine flooding occurs when a waterbody exceeds its “bank-full” capacity because of prolonged, heavy rainfall combined with snowmelt. This type of flooding is often characterized by high peak flows and a large volume of runoff. In the County, riverine flooding can happen anytime between November and April from heavy rains (sometimes combined with snowmelt), increased outflows from upstream dams, or heavy flow from streams. There is often enough warning time with riverine flooding to evacuate people to safer areas.

Flash flooding are events with enormous volumes of water over a short period of time that happen from heavy rainfall over a small drainage area. Flash floods can pop up very quickly and evacuation time is much more limited – early threat detection and warning is critical. Lastly, stormwater flooding usually occurs in areas that have increased runoff from impervious surfaces and inadequate drainage systems.

Calaveras County dramatically drops in elevation from the eastern side (Sierra Nevada) to the western side where rain and snow can contribute to downstream flooding.

The probability of a flood event in Calaveras County is rated as likely, given previous occurrences. The highest at-risk areas are along the Mokelumne and Stanislaus Rivers but the County also has numerous smaller streams, channels, and creeks that can also flood. Overall vulnerability in the County from flooding is high and the extent of a flood event is critical. According to FEMA and Calaveras County 2014 Assessor’s data, there are 730 improved parcels and approximately $222 million of structures and contents in the one percent annual chance floodplain in the County planning area (see Figure 4 in Appendix A). In the unincorporated areas of the County, there are slightly fewer improved parcels and approximately $215 million of structures and contents in the one percent annual chance floodplain.

Regarding population at risk, around 1,400 residents of both the County’s planning area and unincorporated areas are at risk from flooding.

According to the draft 2021 MJHMP, there are 14 critical facilities in the one percent annual floodplain in the unincorporated areas of the County from 2010 Federal Emergency Management Act (FEMA) flood insurance rate maps. Several of the facilities are fire and police stations, as well as powerhouses and dam spillway gates and releases.

The County has a history of flooding events and most recently in 2012, 2017, 2018, and 2019. In 2019, for example, Highway 49 was shut down for hours due to flash flooding and many residents were trapped in their homes. The County was included in a federal disaster declaration that year and with each intensifying event, flooding damage costs the County increasingly more and more.

6.4 Dam Failure (Moderate Risk)
Dams are classified into three categories based on their potential hazard to life and property: 1) High

CALAVERAS COUNTY EXISTING CONDITIONS INTERIM REPORT
N A T U R A L H A Z A R D S 17
Hazard indicates a failure would most likely result in the loss of life; 2) Significant Hazard indicates a failure could result in appreciable property damage, and 3) Low Hazard indicates a failure would result in minimal property damage and loss of life is unlikely. In the County, there are 18 mapped high-hazard dams, 2 unmapped high-hazard dams, 17 mapped significant hazard dams, 8 mapped low-hazard dams, 7 unmapped unclassified dams, and 1 mapped unclassified dam. Many of the mapped high-hazard dams are owned by utility districts, water districts, and power authorities and should one fail, have the potential to impact more than 1,000 people. There are also 7 high-hazard and 16 significant hazard dams located outside Calaveras County, that if breached, could impact Bear Valley, Pioneer, and other localities inside the County.

The 2021 HMP estimates that it is likely that a catastrophic dam failure will affect Calaveras County, but the extent of a failure would be limited. If any of the County’s large dams were to fail – including New Melones, Hogan, Tulloch, Hunters, McKays, Spicer, Camanche, and Pardee – property damage, utility failure, and loss of life could result. Between 10-25% of the County could be impacted by the failure of any one major dam.

There is a history of dam failure in and surrounding Calaveras County. Major historic events include an uncontrolled release from the Melones Dam in 1997, another uncontrolled release from the Don Pedro Dam in Tuolumne County in 1997 that flooded 300 miles, including parts of Calaveras County, and more recently in 2017, storms damaged the Lake Oroville spillways so much that mandatory evacuation orders were issued in Butte, Yuba, and Sutter counties. The 2021 MJHMP provides brief summaries of the potential consequences of dam failures across the County. For example, a sunny day failure of either the Andrew Cademartori Dam or Murphys Forebay could flood approximately 140 residences, roads, and other businesses along Angles Creek before flows would eventually disperse downstream into New Melones Lake.

6.5 Earthquake (Low Risk)
Due to the absence of fault lines, Calaveras County has not experienced any instance of earthquakerelated shaking that has registered on the Modified Mercalli Intensity Scale over recorded history.

Therefore, the probability of damaging seismic ground shaking is unlikely, and the risk of surface fault rupture is low.

6.6 Volcano (Low Risk)
According to the 2021 MJHMP, volcanic activity in the County is negligible and the probability of future occurrences for a volcanic eruption impacting the County in the next 100 years is unlikely. The greatest risk to Calaveras County from a volcanic eruption is the deposition of ash, as this could affect breathing conditions for certain at-risk populations, such as the young, elderly, and those with respiratory conditions. In the event of evacuation, first responders may prioritize these higher-risk populations. Falling volcanic ash can also disrupt communication infrastructure, transportation, and water supplies and reservoirs.

7. Climate Change
This section describes the projected climate change in Calaveras County and its anticipated impact on natural hazards that drive emergency and evacuation situations. This material uses language and data from two primary sources: the Cal-adapt Local Climate Change Snapshot Tool (hereafter the “Cal-adapt Snapshot Tool”)5 and the 2019 Caltrans District 10 Climate Change Vulnerability Assessment Report (hereafter the “Caltrans Climate Change study”).
6 7.1 Temperature Changes
According to the Cal-Adapt Snapshot Tool, the average annual maximum temperature across Calaveras County is most likely to increase +5.3 °F by the end of the century in a medium emissions scenario (RCP4.5) and +8.8 °F by the end of the century in a high emissions scenario (RCP8.5). As shown in the Figure below, there will be similarly significant increases in other high temperature metrics including number of extreme heat days and number of warm nights.

The 2019 Caltrans Climate Change Vulnerability Assessment Summary report identifies several ways in which rising temperatures can impact transportation systems. Water saturation levels and ground conditions can affect foundations and retaining walls. Materials, such as pavements, that are exposed to high temperatures for a long period of time can deform. Higher temperatures could also deteriorate bridge joint seals from expansion, which could impact the bridge structure and accelerate replacement schedules.

An important consideration for the durability and reliability of transportation routes is pavement design.

Pavement design considers two primary criteria: average maximum temperature over seven consecutive days, and the change in absolute minimum air temperature. As temperatures are predicted to rise, designers will need to carefully consider design and the design life of an asset. Assets such as asphalt

pavement are replaced every 20 to 40 years depending on use, while bridges are built to last for 50 years or longer. Higher temperatures, in combination with other events heightened by climate change such as increased precipitation or droughts, could all negatively impact the road network in Calaveras County.

7.2 Precipitation Changes
According to the Cal-Adapt Snapshot Tool, climate change is not projected to significantly increase the projected average annual rainfall across Calaveras County. However, precipitation will likely be delivered in more intense storms and produce much smaller snowpack volumes. As shown in Table 8, the maximum 1-day precipitation is projected to increase by as much as 13% by end-century, and the April snowpack volume measured as snow-water equivalent (SWE) is projected to drop up to 92% under a high emission scenario.

The projected increasing intensity in storms, in conjunction with other changes in land cover and land use, can affect transportation assets in a number of ways such as from landslides, flooding, washouts, erosion, and structural damage. The 2019 Caltrans Climate Change Vulnerability Assessment states that “the primary threat to transportation assets comes not from a higher overall volume of rainfall over an extended period, but rather from larger and more frequent storm events – and their potential for damaging the [state highway system].” Given the widely dispersed population in Calaveras County and its many narrow, mountainous roads, washouts and other road closures from intense precipitation events can make evacuations difficult. Public notification and advance warning systems are critical to timely evacuations.

7.3 Impacts on Wildfire
The projected changes in temperature and precipitation are likely to significantly increase the extent and severity wildfire across Calaveras County. According to the California Adaptation Planning Guide, “warmer weather, reduced snowpack, and earlier snowmelt can be expected to increase wildfire through fuel hazards and ignition risks…An increase in wildfire intensity and extent will increase public safety risks, property damage, and emergency response costs.”7 The Cal-adapt Snapshot Tool shows the

7.4 Impacts on Other Hazards
Compared to wildfire, the effect of climate change on other hazards is generally less significant and more poorly understood. The table below provides a qualitative description of how climate change might affect other hazards based on information in the 2021 MJHMP.

Table 10. Calaveras County climate change impacts on other hazards (Source: 2021 MJHMP) CALAVERAS COUNTY CLIMATE CHANGE IMPACTS – OTHER HAZARDS

HAZARD MAJOR CONSIDERATIONS
Dam Failure - Severe weather causes cracks to the concrete portion of dams and gunite portion of the water delivery flume structures.
- As the cracks freeze during cold events and then thaw during heat events, this expansion and contraction can expand/lengthen the cracks and threaten the integrity and stability of the dam, which may result in structural damage.

Flooding - Flooding could be less likely due to projected drops in soil moisture, or more likely due to projected increases in extreme precipitation events. - The risk of post-wildfire flooding is likely to increase.

Debris Flow - Debris flows could be less likely due to projected drops in soil moisture, or more likely due to projected increases in extreme precipitation.

Earthquake - Climate change is not expected to affect earthquakes.

Volcanic Eruption - Climate change is not expected to affect volcanic eruption.

8. Emergency Planning Documents
The Calaveras County and City of Angels Camp governments have developed several plans that discuss emergency preparedness and evacuation. Appendix C has links to each document.

8.1 Calaveras County General Plan (2019)
The Calaveras County General Plan was developed to guide County growth and promote public health and safety. The plan contains a “Safety Element” section that addresses protecting the County from natural hazards including earthquakes, dam failure, debris flow, flooding and fires. The Safety Element section incorporates the analyses and recommendations of the MJHMP for four different hazards: flood, fire, geotechnical, and emergency evacuation. The Safety Element section is associated with the Calaveras County Emergency Operations Plan (EOP), which plans initial and extended emergency response and the recovery process (as described below).

The Safety Element section sets policies to address the fact that there are “no comprehensive evacuation plans serving most of the County’s population (see pg. S8). Emergency evacuation is challenging in Calaveras County due to a highly dispersed rural population, narrow roads, and mountainous terrain. In addition, there are many campgrounds and recreational facilities with season or intermittent occupants.

As part of its Implementation Program, the Safety Element aims to improve evacuations and emergency planning with the following measures:
• Identification of general evacuation routes, sites, and centers on the Calaveras County GIS site (labeled S1-C);
• Use Dam Failure Inundation Zone maps to ensure that future developments do not locate high residency structures in the inundation area (S-2D);
• Identify road culverts that are undersized and/or contribute to upstream flooding (S-2E); • Continue to participate in and support cooperative fire prevention and response planning efforts (S3G); and • Identification of wildfire specific evacuation routes and preparation of a consolidated map (S-3V).

8.2 Angels Camp 2020 General Plan (2009)
The Angels Camp 2020 General Plan is a detailed look at the Angles Camp community including land use, housing, economic development, and public services and facilities. Like the Calaveras County General Plan, it contains a Safety Element with a summary of the natural hazards facing Angels Camp and the plans in place to address them. The background information and implementation measures are broadly similar to those in the Calaveras County General Plan.

8.3 Angel Camp Flood Plan 2020
The Emergency Operations and Floodwater Plan outlines a strategy for preparedness, readiness, flood flighting, and recovery in the event of a significant event in the City of Angels. The report highlights areas of potential flooding within the City, properties and businesses that would be impacted, floodwater protection and monitoring strategies, and also summarizes the flood fight plan, evacuation priorities, and strategies for public notification. Flooding is a major concern for the City as an event could be triggered by a significant rainfall event or from overtopping of a manmade dam into Angels Creek. In general, areas along China Gulch, Angels Creek, and Greenhorn Creek have flooding potential. Additionally, hydroelectric facilities are located at Angels and Murphys and any uncontrolled release to Angels Creek could result in a flood event. Occupants of residential and commercial properties impacted by a flood event would be the top priority for evacuation. Because flooding along the Angels Creek corridor could overtop the Angels Creek bridge crossing at Vallecito Road, rescue crews should focus on residences along Angles Creek.

8.4 Calaveras County Emergency Operations Plan
The Calaveras County Emergency Operations Plan (EOP) published by the County’s Office of Emergency Services outlines the planned response to extraordinary emergencies associated with natural or human caused disasters. The EOP addresses each phase of an emergency – mitigation, preparedness, response, and recovery. Per the plan, authority and responsibility for evacuations lies with the Calaveras County Sherriff’s Office. In conjunction with the Angels Camp Police Department, the California Highway Patrol, the Sherriff’s Office will work to:
• Expedite the evacuation of persons from hazardous areas • Identify evacuation routes
• Control evacuation traffic
• Institute access control measures to prevent unauthorized persons from entering vacated or partially vacated areas
• Secure the safety and well-being of persons in the affected areas of the emergency • Provide field level coordination of transportation for victims in an emergency.

The California Highway Patrol is responsible for evacuation and movement control on state highways and the local law enforcement agency will primarily control evacuation and movement on other roadways and on off-road areas.

Last Updated November 23, 2022
5 1 Executive Summary
The Calaveras Council of Governments (CalaverasCOG) initiated the Evacuation and Access Needs Assessment and Preparedness Plan ("the Preparedness Plan") to address Calaveras County's emergency and evacuation planning needs. As part of the Preparedness Plan's development, the Hazard Risk and Vulnerability Assessment evaluates the susceptibility of Calaveras County's communities and transportation assets to natural hazards. This assessment supports the identification of high-priority areas and assets for potential strategies to improve the overall resilience of the County's transportation network.

The assessment focuses on impacts to communities and transportation assets, specifically roads and bridges. Because communities and transportation assets are affected by hazards differently, the assessment adopts different technical approaches for each impact type. These distinct approaches are summarized in Section 3.0: Community Assessment and Section 4.0: Transportation Asset Assessment.

The Community Assessment focuses on impacts to people by examining the vulnerability – the potential to experience adverse impacts – of Calaveras communities. Vulnerability is a function of exposure and sensitivity. Exposure refers to the likelihood and degree of physical contact between a hazard and a community, whereas sensitivity refers to a community's ability to cope with hazard exposure. Sensitivity incorporates demographic information, such as socioeconomic status and disabilities and access and functional needs, that influence a community's ability to prepare for, respond to, and recover from hazards. Exposure and sensitivity are equally weighted to produce a single Vulnerability Score for each community.

Figure 1. Community Assessment Approach
The Transportation Asset Assessment focuses on the impacts to the County's overall transportation network by examining the risk to roads and bridges. Risk examines to what degree an individual asset's vulnerability to hazards will impact the larger transportation network. An asset's vulnerability is determined by examining physical exposure to hazards and sensitivity to withstand potential impacts, characterized by structural conditions. To measure risk, this assessment examines vulnerability and criticality, referring to the importance of an asset to the larger transportation network. Criticality is weighted heavier than vulnerability to produce a single risk for each asset that reflects its significance to the overall transportation network.

6 A total of 18 different indicators were identified and used to assess exposure, sensitivity, and, for transportation assets, criticality (Table 1). Some indicators were applied to both the Community and Transportation Asset Assessment, whereas several others were only used where applicable. For example, the local wildfire severity rating was one of the indicators used to assess both community and asset exposure, the pavement condition index was one of the indicators used to assess asset (road) sensitivity, and the average annual daily traffic (AADT) was one of the indicators uses to assess asset criticality. More details on data sources and methods can be found in the following sections.

Table 1. Component-Indicator Matrix for Community and Transportation Assessments Both assessments use a relative framework that assigns scores compared to the rest of Calaveras County. For example, a community's exposure to the flood hazard is determined by the percentage of land area within the 1% or 100-year FEMA floodplain. Among Calaveras communities, this percentage ranges from 0% to 25%. The percentages are reclassified into five score groups based on the actual distribution of the data. Communities are assigned scores from one, containing the lowest percentage values within the County (including 0%), up to five, containing the highest percentage values (including 25%). This reclassification produces final scores that categorize communities based on their flood exposure relative to all other communities in the County.

A total of 28 Address Communities and 1,134 Public Land Survey System (PLSS) Sections were each assigned a Vulnerability Score from 1 (lowest vulnerability) to 5 (highest vulnerability). Similarly, 9,275 road sections, which represent 2,470 miles of roadway including local roads and highway, and 105 bridges were assigned a Risk Score from 1 (lowest risk) to 5 (highest risk). Table 2 lists the highest vulnerability Address Communities and the highest risk roads and bridges, along with each one's exposure to the hazards and stressors considered in this assessment. The report and an appendix contain maps with the geographic distribution of all scores across the county. In addition, supplemental e-files include the score of all the individual components and indicators so users can further understand the drivers for each score.

1.2 Limitations
This Hazard Risk and Vulnerability Assessment relies on readily and the best available datasets identified by the assessment team. Due to gaps and limitations in the available data, this assessment may be missing important aspects of vulnerability and overall risk. For example, there was limited data on the structural conditions of County bridges, roads, and critical facilities. In recognition of these data gaps and the inherent difficulty in using a single scoring metric to capture the many facets of vulnerability, the assessment results are intended to supplement but not replace local professional judgment about the condition, vulnerability, and risk to County communities and transportation assets.

9 2 Overview
The following section provides a broad overview of the Hazard Risk and Vulnerability Assessment, including its purpose, relationship to related efforts, and overall approach.

2.1 Background
The Hazard Risk and Vulnerability Assessment is an effort initiated by the Calaveras Council of Governments (CalaverasCOG) to evaluate the susceptibility of Calaveras County's communities and transportation assets to natural hazards. A key focus of this assessment is to identify areas within the County and its communities and assets that may experience adverse impacts due to natural hazards that impair the County's ability to facilitate evacuations and emergency response activities.

This assessment informs the development of the Calaveras County Evacuation and Access Needs Assessment and Preparedness Plan ("the Preparedness Plan") by identifying priority areas and assets expected to experience more severe natural hazard impacts. This process aims to ultimately identify strategies for these high-risk areas and assets to improve the resilience of the County's transportation network (Figure 3.).

Select Conceptual Strategies for Priority Areas

2.2 Assessment Approach
This Hazard Risk and Vulnerability Assessment focuses on potential adverse impacts of hazards to communities and transportation assets, defined as the following:

Communities
Geographic areas populated by individuals, businesses, and governmental and nongovernmental organizations.

Transportation Assets
Physical structures, including roads and bridges, that facilitate the provision of essential services, such as evacuations, emergency response, and the movement of goods and people.

A community's susceptibility to hazards differs from that of transportation assets. For example, a community's potential to endure adverse effects involves examining social factors that contribute to inhabitants' capability to prepare and respond to hazards. In contrast, a transportation asset's potential to endure adverse effects is a function of physical attributes, like age. In recognition of these differences, this assessment adopted two separate sets of metrics to characterize both types of impacts.

Last Updated November 23, 2022
11 A key output of this assessment is a final score indicating a community's or transportation asset's susceptibility to hazard impacts. This score comprises multiple components that contribute to a community's or asset's overall likelihood of enduring damage or disruption due to a hazard. Each component is characterized through a set of indicators that represent the scale of potential impacts.

Indicators are quantified by specific metrics that quantify potential impacts. Figure 4. illustrates the overall assessment approach, using the Community Assessment as an example.

The framework and methods for communities and assets are found in Section 0: Community Assessment and Section 4.0: Transportation Asset Assessment. Where the assessment adopts identical components, indicators, or metrics, the Community Assessment describes the approach, and the Transportation Asset Assessment refers to that initial description.

12 3 Community Assessment
The Community Assessment examines the susceptibility of Calaveras County's geographic communities and their residents to potential hazard impacts by characterizing vulnerability. Vulnerability refers to the overall degree to which a community is expected to experience adverse impacts due to hazards.

Vulnerability is a function of two components, exposure, and sensitivity, defined as the following:
• Exposure refers to the likelihood and degree to which physical contact between a hazard and a community will occur. This component incorporates hazard characteristics, such as frequency, intensity, geographic scale, and external factors that affect event severity. • Sensitivity refers to the degree to which a community can cope with hazard impacts. This component incorporates the composition of the community that influences its capability to prepare for, respond to, and bounce back after a hazard event.

Each component is comprised of multiple indicators that are quantified through metrics. Metrics use readily available datasets that provide information consistently across geographic areas. Each community is assigned a metric score ranging from a value of one (lowest relative to the County) to five (highest relative to the County). Metrics are weighted equally and then averaged to produce a single component score ranging from one (lowest exposure or sensitivity relative to the County) to five (highest relative to the County). The component scores are multiplied to produce a single Vulnerability Score (Figure 5.).

Figure 5. Community Assessment Components
For the Community Assessment, this process is applied to two geographic scales, Address Communities and Public Land Survey System (PLSS) sections (Figure 6.), which are defined as the following:
• Address Communities as defined by the County in the Calaveras County Open Data Portal. These areas include named communities that are both incorporated and unincorporated. Applying the assessment process to Address Communities can be useful for communicating results to established communities and for planning purposes. However, these areas vary widely by size and shape. • PLSS Sections as defined by the County in the Calaveras County Open Data Portal. The PLSS Sections were delineated by the California Department of Conservation's Geologic Energy Management Division (CalGEM) to support permitting workflows. They are used in this analysis because they can showcase the spatial distribution of community vulnerability in a nearly uniform, high-resolution grid space.

The following section outlines the Community Assessment process by component, providing a summary of indicators and metrics, and concludes with a summary of the results.

3.1 Exposure
Exposure refers to the likelihood and degree to which physical contact between a hazard and a community will occur. Total exposure is characterized by a community's exposure to hazards and stressors. Exposure is the extent to which communities are exposed to hazards that tend to trigger evacuations in Calaveras County. Stressors are conditions that exacerbate hazards, complicating evacuations, such as projected future changes in temperature and precipitation patterns.

3.1.1 Exposure to Hazards
According to the 2021 Calaveras County Multi-Jurisdictional Hazard Mitigation Plan (HMP), Calaveras County is affected by the following 12 hazards:
• Climate Change
• Dam Failure
• Debris Flows (Landslides, Mud Flows,
Avalanches, and Erosion)
• Drought
• Earthquakes
• Flooding
• Land Subsidence (Sinkholes)
• Severe Weather – Extreme Heat
• Severe Weather – High Wind and Tornados
• Severe Weather – Winter Storms and
Extreme Cold
• Volcano
• Wildfires
This assessment focuses on hazards that meet the following three criteria: the potential to trigger an evacuation, the availability of spatial exposure data, and the high risk it poses to Calaveras County. Of the 12 hazards in the HMP, the following three hazards met these criteria: flooding, wildfires, and debris flow. The HMP's risk assessment process ranked wildfires as high risk and flooding and debris flow as serious risks to the region (Table 3). In addition, these three hazards were all identified as priority hazards in a series of climate debrief interviews that were completed as part of this project. See the project report "Climate Debrief Interview Summary Report" for more details CalaverasCOG Hazard Risk and Vulnerability Assessment

3.1.2 Exposure to Stressors
The intensity, frequency, and geographic scale of hazards are influenced by stressors, which refer to conditions or trends that worsen events. These stressors contribute to a community's hazard exposure and affect Calaveras County's ability to facilitate evacuations and emergency services. Stressors are represented by three indicators: precipitation trends, air temperature trends, and economic loss.

Changes to a region's climate, such as precipitation amounts or air temperatures, can create more suitable conditions for floods, wildfires, and debris flow events. The assessment incorporates projections for changes to average annual maximum temperature and annual precipitation.

Economic losses due to hazards create significant post-event stress to communities. Economic losses refer to the average annual damage or harm to buildings, people, and agriculture incurred by any hazard event. The assessment uses estimates of annual economic loss from FEMA's National Risk Index.

3.1.3 Metrics
Each hazard event and stressor contribute to a community's exposure (Figure 7. ). This section defines and describes the process of quantifying each indicator through metrics.

Metrics leverage different datasets and raw values to indicate community exposure, as outlined in Table

4. All metrics are assigned relative scores compared to the rest of Calaveras County, from one (indicating low exposure) to five (high exposure).

The assessment uses readily available datasets that provide scores continuously across geographic areas. An area-weighted average is calculated to produce a single score for each geography to adapt these scores to Address Communities and PLSS Sections.

For example, each community's exposure to flooding is measured using a flood exposure indicator. The metric for the flood exposure indicator is the percentage of land area in each community boundary that is within the 1% or 100-year FEMA floodplain. Among the County's 28 Address Communities, the percentage varies from 0% to 25%. The percentages are reclassified into five score groups, from one containing the lowest percentage values (including 0%) to five containing the highest percentage values (including 25%).

16 The reclassification from the raw metric values to the indicator score uses a statistical clustering algorithm called K-means, similar to the natural breaks or Jenks classification symbology frequently used in standard GIS software. The algorithm assigns the lowest grouping of communities a score of one, the next lowest grouping a score of two, and so forth. The groups vary in size depending on the natural distribution of the data.

3.1.3.1 Methods
This section briefly describes each indicator and the methods adopted to quantify its associated metric's value.

4 Representative Concentration Pathways are standardized scenarios used to model climate impacts. These scenarios represent different trajectories for greenhouse gas concentrations in the atmosphere. Of these scenarios, RCP8.5 reflects the highest future concentrations and is referred to as a high emissions scenario. This assessment selected RCP8.5 as a conservative “business-asusual” scenario to highlight areas and assets with the potential to become increasingly vulnerable to adverse hazard impacts.

17 Flood Exposure
Flooding occurs when water levels in rivers, streams, and other waterbodies rise due to prolonged precipitation and overflows onto normally dry land. A community's flood exposure is measured by the percentage of the land area contained with the 1% annual chance floodplain, delineated by Special Flood Hazard Areas (SFHAs). The 1% annual chance floodplain refers to the geographic area that will be inundated by a flood event with a 1% probability of occurring or being exceeded in any given year. The FEMA Flood Zones shapefile was downloaded from the Calaveras County GIS website.5 Communities that contain significant land area within the floodplain are more likely to be exposed to flooding than those with no or limited area. Address Communities and PLSS Sections are assigned scores from one (no-to-limited land area in the floodplain) to five (significant land area in the floodplain).

Wildfire Severity
Wildfires are unplanned fires in natural areas that typically ignite due to multiple factors, including air temperatures and moisture content, presence of vegetation, wind direction and strength, drought conditions, and human-initiated activities. Wildfire exposure in the vulnerability assessment is determined by Fire Severity Zones, including Moderate Hazard, High Hazard, and Very High Hazard. The zones are determined based on potential fuels, fire-weather conditions, and terrain, and they represent potential fire hazard exposure to structures and other infrastructure assets. The Fire Severity Zones shapefile was downloaded from the CAL FIRE website.6
Address Communities and PLSS Sections tend to contain multiple zones. Zones are reassigned a numeric value of zero (no Fire Severity Zone present) to three (Very High Hazard) to attribute a single score to these geographies. An area-weighted average is calculated based on the proportion of each Fire Severity Zone contained within community boundaries. Address Communities and PLSS Sections are assigned scores from one (lowest average wildfire severity) to five (highest average wildfire severity).

Debris Flow Susceptibility
Debris flows occur when large masses of soil and fragmented rock become loose and rapidly move down mountainsides or steep slopes, endangering development in its path. Three types of debris flow events affect Calaveras County: landslides (including rockslides), mudflows, and avalanches. Landslides occur when hill slope materials break away due to heavy rainfall or snowmelt, erosion, weakened materials, or earthquakes. Mudflows occur when heavy rainfall, snowmelt, or high groundwater levels flow through cracked bedrock or cause extensive erosion, triggering the downward movement of soils or sediments.

Avalanches refer to the fast, downward movement of snow and occur when snow fractures due to multiple factors, including water, temperature, slope orientation and steepness, vegetation, and snowpack conditions. All three types of events can occur with little warning and have the potential to harm communities in their paths.

The assessment uses landslide data as an approximation for debris flow susceptibility. The US Geological Survey's Landslide Susceptibility dataset evaluates exposure to debris flow events. This dataset evaluates an area's vulnerability to potential landslide incidences based on slope and soil type.

Areas are assigned one of five classifications from Low Incidence to High Incidence. The landslide susceptibility raster was downloaded from the California Department of Conservation GIS server.7

18 Address Communities and PLSS Sections tend to contain multiple classes. An area-weighted average is calculated based on the proportion of each class contained within community boundaries to assign a single score to these geographies. Address Communities and PLSS Sections are assigned scores from one (lowest average landslide susceptibility) to five (highest average landslide susceptibility).

Temperature Change
Temperature change refers to the difference in the average annual maximum temperature between baseline historical observations (1961 to 1990) and the end of the century (2099) under a high emissions scenario (RCP8.5). By 2099, Calaveras County's average annual maximum temperature is expected to be 8.8° Fahrenheit hotter than that witnessed between 1961 and 1990. Temperature increases are expected to intensify the extent and severity of wildfires and debris flow across Calaveras County. Hotter seasonal temperatures, reduced snowpack, and earlier snowmelt will collectively create more potential fuel and suitable conditions for wildfires to ignite and spread. Temperature increases will accelerate snowmelt rates, elevating the risk for potentially severe debris flow as soils become saturated and water accumulates along slide planes between soil layers.

Cal-Adapt provides temperature change projections in an approximately four-mile-by-four-mile gridded raster.8 An area-weighted average is calculated to assign a single score to each Address Community and PLSS Section. Address Communities and PLSS Sections are assigned scores from one (limited increase) to five (high increase).

Precipitation Change
Precipitation change refers to the difference in the annual precipitation between baseline historical observations (1961 to 1990) and the end of the century (2099) under a relatively high emissions scenario (RCP8.5). By 2099, Calaveras County's average annual precipitation is expected to fall 0.2%, and snowpack volume is expected to fall 92% compared to levels recorded between 1961 and 1990. Reduced precipitation and snowpack are expected to intensify the extent and severity of wildfires across Calaveras County by creating more potential fuel for wildfires to ignite and spread.

Cal-Adapt provides precipitation change projections in an approximately four-mile-by-four-mile gridded raster.9 An area-weighted average is calculated to assign a single score to each Address Community and PLSS Section. Address Communities and PLSS Sections are assigned scores from one (limited change) to five (significant change).

All-Hazards Economic Loss
Economic loss is the expected annual loss in dollars due to hazards in any given year. These losses include damage to buildings and agriculture and impacts to people, measured by fatalities and injuries.

Using data from the National Risk Index, the assessment incorporates economic loss scores for 18 hazards down to the census tract level. An area-weighted average is calculated to assign a single score to each Address Community and PLSS Section. Address Communities and PLSS Sections are assigned scores from one (limited economic loss) to five (high economic loss). The data was downloaded from the FEMA website.10

19 3.2 Sensitivity
Sensitivity refers to the degree to which a community can cope with hazard impacts. This component incorporates indicators related to community composition that influence its capability to prepare for, respond to, and bounce back after a hazard event.

3.2.1 Community Characterization
A community's sensitivity is determined by the shared social characteristics of its residents, captured by specific demographic indicators that are known to amplify hazard impacts, such as median household income, poverty rates, or access to a vehicle. Communities with populations that exhibit higher rates of these characteristics are more likely to experience adverse hazard impacts.

3.2.2 Metrics
The assessment leverages three indicators that capture different demographic information to quantify community sensitivity (Figure 8.). The following section defines and describes the process of quantifying each indicator through a specific metric.

The metrics leverage datasets and raw values to indicate community sensitivity, as outlined in Table 5. All metrics are assigned relative scores compared to the rest of Calaveras County, from one (indicating low sensitivity) to five (high sensitivity).

21 Social Vulnerability
Social vulnerability refers to the susceptibility of social groups to adverse hazard impacts, including death or injury, financial loss, or disruption of livelihood. Multiple demographic factors determine a community's SoVI score. Specifically, these factors include income, poverty rates, race and ethnicity, vehicle access, housing tenure, English proficiency, age, disabilities, and access and functional needs. The SoVI data was downloaded as part of the FEMA National Risk Index.11 The SoVI score is a national dataset developed by the University of South Carolina’s Hazards and Vulnerability Research Institute.12 SoVI assigns scores down to the census tract level. An area-weighted average is calculated to assign a single score to each Address Community and PLSS Section. Address Community and PLSS Section are assigned scores from one (low social vulnerability relative to the rest of the County) to five (high social vulnerability).

Disadvantaged Status
Defined by the California legislature, disadvantaged communities refer to census tracts that meet one of two thresholds: tracts with median household incomes at or below 80% of the statewide median income; or those with median household incomes at or below the "low income" threshold identified by the California Department of Housing and Community Development. 13 Each Address Community and PLSS Section is assigned a score based on the percentage of its area that meets these criteria, from one (lowest percentage share relative to the rest of the County) to five (highest percentage).

Economically Distressed Areas
Economically distressed areas refer to communities exhibiting low population densities, higher unemployment relative to the state, and annual median household incomes less than 85% of the statewide median household income. 14
Each Address Community and PLSS Section is assigned a score based on the percentage of its area that meets these criteria, from one (lowest percentage share relative to the rest of the County) to five (highest percentage).

3.3 Vulnerability

3.3.1 Vulnerability Approach
Vulnerability refers to the degree to which a community is expected to experience adverse impacts due to hazards. This component incorporates indicators related to community composition that influence its capability to prepare for, respond to, and bounce back after a hazard event.

For exposure and sensitivity, metrics are averaged across indicators to produce a single composite score for each component. These component scores are multiplied to produce a single Vulnerability Score (Figure 9.). The following section summarizes the Community Assessment results and highlights key findings.

23 3.3.2 Address Communities Results
The following section summarizes the Community Assessment results for Address Communities, organized by component.

3.3.2.1 Exposure
Address Communities exhibiting the highest hazard exposure are rural and/or higher elevation areas northeast of State Route 49 (Map 1). These communities include Dorrington, West Point, San Andreas, Mountain Ranch, Sheep Ranch, Paloma, Mokelumne Hill, and Vallecito. Higher exposure scores were driven primarily by high exposure to landslides and wildfires. Note that the wildfire severity rating was not available in all areas including parts of Hathoway Pines and Avery communities, which resulted in a lower apparent wildfire severity score, and a lower overall exposure score. The wildfire severity rating map shows all of the areas with missing data. Future work could aim to fill data gaps with better information.

3.3.2.2 Sensitivity
Address Communities exhibiting the highest sensitivity are rural areas located centrally in the County (Map 2). These communities include Douglas Flat, White Pines, Wilseyville, Mountain Ranch, Glencoe, and Rail Road Flat. High sensitivity scores were driven by a high concentration of census tracts meeting the thresholds for Disadvantaged Communities and Economically Distressed Areas.

3.3.2.3 Vulnerability
Mountain Ranch received the highest Vulnerability Score of all Address Communities due to high exposure to wildfire and landslides and high sensitivity, driven by the Disadvantaged Communities and Economically Distressed Area indicators. Most communities exhibiting high vulnerability are primarily rural communities to the north of the County (Map 3). In contrast, communities exhibiting the lowest vulnerability are those in more developed areas along the County's southwestern boundary. Some of these communities exhibited moderate exposure but received the lowest sensitivity scores.

3.3.3 PLSS Sections Results
The following section summarizes the Community Assessment results for PLSS Sections, organized by component.

3.3.3.1 Exposure
Overall, sections exhibiting the highest hazard exposure are in the central and northeastern portions of the County, whereas those with the lowest are predominately located to the southwest (Map 4). High exposure in the northeastern sections was driven primarily by high landslide exposure and more significant expected changes to both annual temperatures and precipitation amounts.

3.3.3.2 Sensitivity
Sections exhibiting the highest sensitivity are located centrally in the County (Map 5). This pattern aligns with the Address Communities results, except for sections covering San Andreas, Murphys, Angels Camp, and City of Angels. The higher resolution approach shows that some areas within these Address Communities may exhibit higher sensitivity to hazards than the entire community.

3.3.3.3 Vulnerability
Sections exhibiting the highest Vulnerability Scores are located centrally in the County (Map 6). These sections exhibited among the highest exposure scores and tended to have the highest sensitivity scores within the County. These sections cover areas that are primarily rural and located in higher elevations.

Sections exhibiting the lowest vulnerability tend to be clustered in more developed areas along the County's southwestern boundary. Some of these sections exhibited moderate exposure but received the lowest sensitivity scores.

24 4 Transportation Asset Assessment
The Transportation Asset Assessment examines the susceptibility of the County's transportation assets to potential hazard impacts by characterizing risk. Risk refers to the potential for adverse consequences where something of value is at stake, and the occurrence and degree of an outcome are uncertain. An asset's risk to hazard impacts is a function of two components: vulnerability and criticality, defined as the following:
• Vulnerability refers to the overall degree to which an asset is expected to experience adverse impacts due to hazards. Vulnerability is a function of an asset's exposure and sensitivity to hazards, defined as the following:
• Exposure refers to the likelihood and degree to which physical contact between a hazard and an asset will occur. Exposure indicators incorporate event characteristics, such as frequency, intensity, geographic scale, and exposure to hazard stressors. • Sensitivity refers to the degree to which an asset is expected to cope with hazard impacts.

Sensitivity indicators approximate an asset's structural composition, such as road surface and the surrounding community that the asset serves.
• Criticality refers to an asset's importance to the surrounding community. This component incorporates indicators related to an asset's significance to the larger transportation network, such as its frequency of use.

This assessment focuses on evaluating the risk to roads and bridges. This analysis did not include culverts due to a lack of readily available data. To fill this data gap, impacts to culverts may be identified through qualitative means, like community outreach and interviews, to include in considerations for priority locations.

Each component is quantified by multiple indicators that are quantified through metrics. Metrics use readily available datasets that provide information about road and bridge characteristics. Each road or bridge is assigned a metric score relative to all roads or bridges within Calaveras County, from one (lowest) to five (highest). Metrics are weighted equally and averaged to produce a single component score (Figure 10).

An asset's risk is a function of its vulnerability and criticality. Risk scores are assigned using a lookup matrix (refer to Section 4.3.1 for more details and the matrix figure). The matrix assigns higher weights to more critical assets, reflecting their relative importance to Calaveras County and its transportation network. For example, a bridge with a high criticality score receives a higher Risk Score than a less critical bridge, even if both brides receive the same Vulnerability Score.

25 The Transportation Asset Assessment considers two types of transportation assets: roads and bridges. • Roads: The roads dataset was obtained from the Calaveras County Open Data Portal.15 The dataset was clipped to the Calaveras County boundary to remove a few roads that extended into neighboring counties. The final road dataset contains a total of 9,275 road sections, which represent 2,470 miles of roadway including local roads and highway. The distribution of roadway length by road type is provided in Table 6.

Table 6. Distribution of roadway length by road type.
• Bridges: The bridge assets were downloaded from the California bridges in the 2021 National Bridge Inventory.16 There are a total of 105 bridges across the county. A review of the bridge locations suggests that some bridges might be missing from the inventory (e.g., in the Arnold address community). Future work might try to identify a more complete bridge dataset.

The process for evaluating the sensitivity and criticality of each asset type varies based on the asset characteristics and functions. The process for evaluating exposure is consistent for each asset type.

Additionally, this assessment methodology differs from efforts by others to evaluate Calaveras County's transportation assets, specifically the methodology used to assess bridges in the Caltrans District Adaptation Priorities Report (2020). This assessment adopted different methods and metrics to incorporate social vulnerability components and structural and condition metrics to help support decisionmaking related to evacuations at the County level. A comparison of results between this assessment and the Caltrans report is discussed in Section 4.3.3.3.

The following section outlines the Transportation Asset Assessment process by component, summarizing indicators and metrics and concluding with results.

4.1 Vulnerability

4.1.1 Exposure
Asset exposure refers to the likelihood and degree to which physical contact between a hazard and asset will occur. Exposure indicators incorporate indicators related to event characteristics, such as frequency, intensity, geographic scale, and event stressors.

The assessment focuses on the exposure to three hazards: flooding, wildfires, and debris flow (see explanation in Section 3.1.1). In addition to hazard exposure, the assessment examines assets' exposure to stressors. Two indicators represent stressors: precipitation trends and air temperature trends (see

27 4.1.1.1.1 Methods
The following section provides abbreviated descriptions of each indicator and the methods adopted to quantify its associated metric's value. For additional information, refer to Section 3.1.3.1: Methods.

Flood Exposure
A roadway's flood exposure is determined by intersection with the 1% annual chance floodplain, delineated by Special Flood Hazard Areas (SFHAs). Roads that fall within the floodplain are more likely to be exposed to flooding than those outside the floodplain. Roads are assigned scores based on the asset's intersection with the floodplain in a binary fashion. Assets that do not fall within the floodplain receive a one (asset faces no flood exposure), and those that do receive a five (asset is exposed to flooding).

A bridge's flood exposure is determined by its waterway adequacy, referring to the ability of water to pass or flow through its structure. A bridge with insufficient waterway adequacy can experience overtopping water that can cause traffic delays. The National Bridge Inventory assigns bridges a Waterway Adequacy Score based on potential overtopping frequency and level of service (traffic capacity). A bridge with a high chance of experience overtopping and that has a higher level of service (such as an interstate or freeway) receives a higher Waterway Adequacy Score. In Calaveras County, bridges received Waterway Adequacy Scores ranging from two (occasional or frequent overtopping and potentially severe traffic delays) to nine (remote chance of overtopping). Closed bridges receive a score of zero, and bridges that do not cross waterways are not ranked. For the Transportation Asset Assessment, Waterway Adequacy Scores are reclassified from one (lowest chance of overtopping and traffic delays) to five (highest chance of overtopping).

Wildfire Severity
Asset exposure is determined by its intersection with Fire Severity Zones, including Moderate Hazard, High Hazard, and Very High Hazard.Roads are assigned scores based on a length-weighted average based on the proportion of their length within each Fire Severity Zone. Roads receive scores from one (no data) to five (highest length-weighted average Fire Severity Zone). Bridges are assigned scores based on the zone with which it intersects.

Debris Flow Susceptibility
An asset's debris flow susceptibility is determined by its intersection with areas of high landslide incidence and susceptibility, indicated by the Landslide Susceptibility dataset. Each road segment is scored using the length-weighted average landslide susceptibility class. Roads receive scores from one (lowest lengthweighted average susceptibility class) to five (highest length-weighted average susceptible class).

Bridges are assigned scores based on the susceptibility class at its point location.

Temperature Change
Cal-Adapt provides temperature change projections in an approximately four-mile-by-four-mile gridded raster. Roads are assigned scores based on an area-weighted average based on the proportion of their mileage that overlaps with different tracts and their respective projections. Roads receive scores from one (lowest increase) to five (highest increase). Bridges are assigned scores based on the projection for the census tract with which it intersects.

Precipitation Change
Cal-Adapt provides precipitation change projections in an approximately four-mile-by-four-mile gridded raster. Roads are assigned scores based on an area-weighted average based on the proportion of their mileage that overlaps with different tracts and their respective projections. Roads receive scores from one (limited change) to five (high change). Bridges are assigned scores based on the projection for the census tract with which it intersects.

28 4.1.2 Sensitivity
Sensitivity refers to the degree to which an asset is expected to cope with hazard impacts. Sensitivity indicators incorporate indicators related to an asset's structural composition, such as road surface and the surrounding community that the asset serves.

4.1.2.1 Sensitivity Approach
An asset's sensitivity is determined by physical characteristics critical to its function and the social characteristics of the surrounding community. Asset sensitivity varies based on its type. The Transportation Assessment characterizes sensitivity by two types of indicators:
• Structural conditions refer to the physical attributes of a road or bridge that indicate potential deficiencies. Specific attributes, like road pavement materials or scour potential, indicate that an asset is more likely to endure damage or disruption during a hazard. • Community vulnerability refers to the vulnerability of the PLSS Section community surrounding the asset. This indicator is derived from the process described in Section 3.0: Community Assessment.

4.1.2.2 Metrics
The Transportation Asset Assessment characterizes sensitivity through distinct metrics for each asset type (Figure 11.). The following section defines and describes the process of quantifying each indicator through metrics.

Metrics leverage different datasets and raw values to indicate asset sensitivity, as outlined in Table 8. All metrics are assigned scores from one (indicating low sensitivity) to five (high sensitivity).

30 4.1.2.2.1 Methods
This section briefly describes each indicator and the methods adopted to quantify its associated metric's value.

Road Surface
Unpaved or dirt roads are more likely to experience flood and debris flow damage than paved roads.

Calaveras County road data indicates whether a road is paved or unpaved, or its surface materials are unknown. Roads are assigned a score in a binary fashion, receiving one (low sensitivity) if they are paved or a five if they are dirt or unpaved (high sensitivity).

Pavement Condition Index
A road's ability to withstand damage depends on physical conditions, such as the presence of cracks or potholes on its surface. A newly constructed or maintained road is less likely to endure adverse impacts than one older or has not recently been maintained. The Calaveras County 2019 Pavement Management Program Update produces a Pavement Condition Index that measures a roadway's pavement condition from zero (poor condition) to 100 (pristine condition). The index considers several factors that affect pavement conditions, including the surrounding environment, traffic volumes and loads, surface materials, and age.

For this assessment, the Pavement Condition Index scores were spatially joined to the Calaveras County road dataset used for this effort. These scores are reclassified from one (worst conditions) to five (best conditions). Roadways lacking data are assigned the median value of all index scores in Calaveras County.

Bridge Age
Older bridges may exhibit more deficiencies or have been built under design requirements that have since been improved. The National Bridge Inventory includes what year a bridge was built or reconstructed. Bridges are assigned a score indicating their age, ranging from one (low sensitivity due to young bridge age) to five (high sensitivity due to old bridge age). Bridges lacking data are assigned the median score for all bridges in Calaveras County.

Bridge Structural Conditions
Structural conditions indicate the overall robustness of a bridge. The National Bridge Inventory includes data on inspections that characterize a bridge's structural conditions. Bridges are assigned a score indicating structural conditions, ranging from one (most structurally sound) to five (least structurally sound). Bridges lacking data are assigned the median structural score of all bridges in Calaveras County.

Bridge Scour
Bridge scour refers to sediment removal around a bridge's foundation, such as its abutments or piers. The presence of scour and scour-related conditions is associated with bridge failure during flood events. The National Bridge Inventory assigns bridges a Scour Critical Ranking based on observed scour or the potential for scour to occur based on previous studies. The Scour Critical Ranking assigns bridges a score from zero (bridge failure and closed to traffic) to nine (bridge foundation on dry land well above flood evaluations). A bridge does not receive a ranking if it does not cross a waterway; has not been evaluated for scour; or crosses tidal waters and is considered low risk.

For this assessment, Scour Critical Ranking scores are reclassified from one (low chance of scouring or no scour present) to five (scour observed or possible). Bridges lacking data are assigned the median value of all scour scores in Calaveras County.

Community Vulnerability
Assets are assigned a Community Vulnerability Score based on the encompassing PLSS section. For more details on the methods to produce these scores, refer to Section 3.0: Community Assessment.

CalaverasCOG Hazard Risk and Vulnerability Assessment
Last Updated November 23, 2022
31 4.2 Criticality
Criticality refers to an asset's importance to the surrounding community. This component incorporates indicators related to an asset's significance to the continuous operation of the larger transportation network. The Transportation Assessment characterizes criticality by examining two types of indicators:
• An asset's frequency of use indicates how much a community depends on it to travel. The frequency of use is indicated by the average annual daily traffic recorded for bridges and roads. • An asset's redundancy indicates how easily an asset can be substituted with another in the same transportation network. More redundant assets are less critical to the network, whereas those that cannot be replaced are essential to facilitate travel throughout Calaveras County.

4.2.1 Criticality Approach
Criticality is characterized by distinct metrics for each asset type (Figure 12.). The following section defines and describes the process of quantifying each indicator through specific metrics.

Metrics leverage different datasets and raw values to indicate asset criticality, as outlined in Table 9. All metrics are assigned scores from one (indicating low criticality) to five (high criticality).

33 4.2.2 Metrics
This section briefly describes each indicator and the methods adopted to quantify its associated metric's value.

Road Type
A road type refers to the level of service it aims to provide. Calaveras County road data assigned each roadway a qualitative type, such as highway, main roads, or private driveways. Road types that can serve higher traffic levels are considered more critical to the road network because if these roads become impassable, it will affect a larger number of travelers than a small or private roadway. Roads were assigned the scores outlined in Table 10.

Table 10. Road Types Scores
Bridge Detour Distance
Some bridges are important connectors for isolated communities, and their closures can cut off travelers from other neighborhoods or parts of the region. Detour distances indicate the miles a traveler must go to circumvent a bridge in the event of its closure. Higher distances indicate that a bridge is vital to the surrounding area's connectivity to the rest of the region, whereas lower distances indicate that travelers have other route options. Bridges were assigned a score from one (lowest detour travel distances) to five (highest detour travel distances).

Average Annual Daily Traffic
Average annual daily traffic indicates the frequency with which a road or bridge is used. An asset with higher traffic volumes is more critical to the surrounding region, as more people and businesses depend on it. These roadways' safe and clear passage is also essential to facilitate evacuations and provide emergency services. Assets are assigned scores from one (lowest traffic counts) to five (highest traffic counts).

4.3 Risk

4.3.1 Risk Approach
Risk refers to the potential for adverse consequences where something of value is at stake, and the occurrence and degree of an outcome are uncertain. An asset's risk is a function of its vulnerability to adverse hazard impacts and criticality to the larger region.

Metrics are averaged across vulnerability and criticality indicators to produce a single composite score for each component. Based on these component scores, a Risk Score is assigned using a lookup matrix (Table 11). The matrix assigns higher weights to more critical assets, reflecting their relative importance to Calaveras County and its transportation network. For example, a bridge with a high criticality score receives a higher Risk Score than a less critical bridge, even if both brides receive the same Vulnerability Score.

4.3.2 Roads Results
The following section summarizes the Transportation Asset Assessment results for roads, organized by component. These sections identify high vulnerability routes, some of which that cross into neighboring jurisdictions. Recognizing the shared reliance on these critical roadways, CalaCOG plans to coordinate evacuation planning needs and potential project development with these jurisdictions.

4.3.2.1 Vulnerability
Roads exhibiting the highest vulnerability are clustered in West Point along State Route 26 on the County's northern border and Camp Connell along Highway 4 on the southern border (Map 7). These results correlate with previously identified at-risk routes, determined through the Climate Debrief Interviews conducted to develop the Preparedness Plan. Specifically, Calaveras officials identified Highway 4 as a road critical for ingress and egress during emergencies and historically has had access issues during winter storms due to fallen trees, limbs, and power lines blocking the route. Overall, in these areas, high vulnerability is driven primarily by high wildfire exposure and the presence of predominately unpaved roadways. The communities surrounding these roadways also exhibited the highest Community Vulnerability Scores in the County.

4.3.2.2 Criticality
Calaveras County's most critical roadways include segments of Main Street, West St. Charles, and Highways 4, 12, 26, and 49 (Map 8). These roads have higher traffic capacities and are essential to the County's overall transportation network. During the Climate Debrief Interviews, Calaveras officials identified Highway 4 as a critical road for ingress and egress during evacuations. Many roads in rural areas exhibit low criticality scores. These roads may be necessary to nearby communities, but they likely have limited capacity and connections to other vital roads in the County's transportation network.

4.3.2.3 Risk
Roads exhibiting the highest risk include segments of Highways 4 and 49 (Map 9). These roads exhibit moderate vulnerability but high criticality to the County's overall transportation network, driving their higher Risk Scores. Roads exhibiting the second-highest Risk Scores include additional segments of Highways 4 and 49, major thoroughfares (such as Highways 12 and 26, Main Street, and East and West St. Charles Streets), and several rural roads in Rail Road Flat, West Point, Mountain Ranch, Murphys, and Wilseyville. The high risk of these rural roads is driven by high exposure and high Community Vulnerability scores, despite lower criticality scores.

35 These results correlate with previously identified at-risk routes, determined through the Climate Debrief Interviews conducted to develop the Preparedness Plan. Highway 4 has been previously identified as a critical route for ingress and egress during evacuations and access issues during winter storms.

Additionally, Calaveras officials identified Highway 49 as a concern for evacuations and noted that the route was shut down for three to four hours due to the 2020 O'Reilly Fire.

4.3.3 Bridges Results
The following section summarizes the Transportation Asset Assessment results for bridges, organized by component.

4.3.3.1 Vulnerability
The majority of the County's most vulnerable bridges are located north of Highway 49 (Map 10). Bridges exhibiting the highest vulnerability are located primarily in the central and northern portions of the County.

High vulnerability in these areas is driven primarily by high wildfire exposure and high Community Vulnerability scores.

4.3.3.2 Criticality
Out of the 32 bridges with the highest criticality score, most are clustered around the City of Angels, Vallecito, and Angels Camp (Map 11). These bridges tend to have higher average annual daily traffic counts than other bridges within the County. However, at least two of the County's most critical bridges are in northern rural areas (West Point and Wilseyville). The criticality of these bridges is driven primarily by the high scores for detour distance.

4.3.3.3 Risk
Bridges exhibiting the highest risk in Calaveras County are typically centrally located in Mountain Range and Sheep Ranch (Map 12). Only one of these bridges serves high traffic values. The remaining bridges tend to exhibit low average annual daily traffic counts, possibly due to their rural locations. However, these bridges typically exhibit the highest hazard exposure and detour distance scores, indicating their importance to the transportation network.

36 4.3.3.3.1 Results Comparison
The following section summarizes key differences between this assessment and the Caltrans Adaptation Priorities Report for District 10, including Calaveras County. The Caltrans Report assessed the vulnerability of Caltrans-owned roads and bridges to climate-influenced hazards. The CalaverasCOG assessment builds off this previous effort but adopts different metrics and methods tailored to Calaveras County's unique hazard exposure, asset inventory, and specific evacuation-related needs. For example, the Caltrans report studies 248 Caltrans-owned bridges, of which 19 are in Calaveras County. This assessment examined a broader set of assets by using the National Bridge Inventory to select the 105 bridges located in Calaveras County.

Additionally, each assessment focused on different hazards to determine asset exposure. As discussed in previous sections, this assessment focuses on hazard exposure to flooding, wildfires, and debris flow.

The Caltrans report focuses on riverine flooding, sea level rise, and storm surge flooding. Sea level rise and storm surge flooding were not included in this process since Calaveras County is not exposed to these hazards. As a result, these methodologies emphasize different types of hazard exposure for bridges. In addition to considering hazard exposure and structural condition, the CalaverasCOG assessment incorporates a social vulnerability component not included in the Caltrans evaluation.

Further, both the Caltrans report and this assessment apply a relative framework to produce final scores or results compared to all assets examined. For example, this assessment assigns risk and Vulnerability Scores relative to the 105 assets contained in the National Bridge Inventory. The Caltrans report assigns bridges a priority score compared to the 248 Caltrans-owned bridges, and the results for Calaveras County represent just a subset of the District 10 assessment. Due to all the factors discussed above, this assessment produced different results from the Caltrans Report (Table 12) CalaverasCOG Hazard Risk and Vulnerability Assessment

38 5 Climate Debrief Interview Comparison
As part of the Preparedness Plan's development, four climate debrief interviews were conducted with seven subject matter experts between February 16 and February 22, 2022. The interviewees represented various organizations and roles in natural hazard management and response across the county, including City of Angels Camp, Calaveras County, and Caltrans. The interviews are summarized in more detail in a separate project report titled “Climate Debrief Interview Summary Report”.

The interviewees identified several areas and assets across the county that may be at especially vulnerable to natural hazards and/or especially critical to the operation of the transportation network.

While very valuable, these observations were too qualitative to be incorporated into the system-wide hazard risk and vulnerability assessment scores. Instead, the observations are summarized below and compared as closely as possible with the assessment results. • Airola Fire: In August 2021, the Airola Fire resulted in evacuations and temporary road closures near River Canyon in the Vallecito address community. Based on this assessment, this community has a high wildfire severity score (4 out of 5).
• Salt Fire: In August 2020, the Salt Fire caused temporary road closures near Salt Springs Reservoir in the Copperopolis address community. Based on this assessment, this community has a moderate wildfire severity score (3 out of 5).
• O’Reilly Fire: In July 2020, the O’Reilly Fire temporary closed Highway 49 in the City of Angle Camp address community. Based on this assessment, this community has a low wildfire severity score (1 out of 5).
• Butte Fire: In September 2015, the Butte Fire caused closures and evacuations in the Mokelumne Hill, Rail Road Flat, Mountain Road, and San Andreas address communities. Based on this assessment, all of these communities have the highest wildfire severity score (5 out of 5). • Winter Storms: In 2017 and 2018 winter storms closed Highway 26 and prompted a federal disaster declaration in the county. Based on this assessment, the average risk score for the segments of Highway 26 is high (4 out of 5).
• Evacuation Routes: Interviewees identified Highway 49 and Highway 4 from the City of Angles to Ebbetts Pass as critical for evacuations. Based on this assessment, the segments of both highways have the highest criticality (5 out of 5).
• Angels Camp Vulnerable Roads: Interviewees identified the following roads in City of Angels Camp as vulnerable to natural hazards: Birds Way, Finnegan Lane, Bush Street, Echo Street, and Crystal Street. Based on this assessment, these roads have a moderate criticality (3 out of 3) and risk score (3 out of 3).
• Angels Camp Subdivisions: Interviewees identified the following neighborhoods and subdivisions as vulnerable to hazards due to access limitations: Big Horn Mobile Park, Greenhorn Creek, Stelte Park near Angels Camp, Kiva recreational area, Diamond XX , Circle XX, and Bar XX. Based on this assessment, the Angels Camp and City of Angles Camp communities, which contains these subdivisions, have has the lowest (1 out of 5) and low (2 out of 5) community vulnerability, respectively.
• City of Angel Camp Bridge: Interviewees identified an old two-lane bridge at the southern end of City of Angels Camp as critical to local transit and evacuation. Based on this assessment, assuming this is structure number 30-0019 built in 1909, this bridge has the highest criticality score (5 out of 5) and a high risk score (4 out of 5).
• O’Byrnes Ferry Bridge: Interviewees noted that trucks have hit the road abutments at this bridge, which cause major traffic delays. Based on this assessment, the bridge has the highest criticality (5 out of 5) and high risk (4 out of 5)
In summary, the feedback from the interviews was generally consistent with the results of the assessments. For example, most of the wildfires occurred in areas with moderate or higher wildfire risk, CalaverasCOG Hazard Risk and Vulnerability Assessment
Last Updated November 23, 2022
39 and most of the roads and bridges identified as important for evacuation had the highest criticality. There were, however, important differences, especially at the local level. For example, the small (5 acre) O’Reilly fire occurred in an area with the lowest wildfire severity score. Furthermore, the assessment seemed to underestimate the vulnerability of some local roads and neighborhoods in the Angels Camp region. The assessment might be improved by more explicitly considering neighborhood access (including gated entrances) as well as snow and wind hazards that cause fallen branches and other obstacles.
6 Assessment Summary
The following section summarizes the combined results from the Community and Transportation Asset Assessments. Mountain Ranch received the highest Vulnerability Score of all address communities due to a combination of high exposure to wildfires and landslides and high social vulnerability (Map 13). In Mountain Ranch, there are several high-risk bridges, including structures crossing Rail Road Flat Road, South Jesus Maria Road, and Mountain Ranch Road. Overall, the northern portion of Calaveras County contains a significant cluster of high vulnerability communities and high-risk bridges and roadways.

Specifically, Rail Road Flat, Wilseyville, and West Point received high Vulnerability Scores. These three communities also exhibit high Sensitivity Scores, particularly West Point, which received the highest possible score for social vulnerability. Within these communities, high-risk roads include Baily Ridge Road, Blue Mountain Road, Cooks Camp Road, Dorothy Way, Fay Street, Grinding Rock Court, and Patricia Way. These communities contain several of the County’s highest risk bridges, including structures crossing Ridge Road and Jesus Maria Road in Rail Road Flat, Schaad Road in Wilseyville, and Forest Route 07N28 in West Point.

Priority Corridors
2 1. Introduction
The Calaveras County Council of Governments (CCOG) is developing an Evacuation and Access Needs Assessment and Preparedness Plan for Calaveras County. The next step in developing this plan is identifying residents' priority routes and communications during evacuation events. Two tools were utilized to understand how the County functions during an evacuation event. Section 2 presents the results of this data platform which utilizes location data of devices and vehicles to understand which routes residents currently use to travel through and exit the County. Section 3 presents the results of a community-wide survey designed to understand concerns related to evacuation routes and communication platforms. And Section 4 presents projects aimed at mitigating the risks along the priority corridors.

2. Priority Corridors
A foundational element of this evacuation needs assessment is understanding the County's current roadway network use. For example, which roads does each community rely on? Which roads are the most heavily traveled? And which local roads are used as bypasses or parallel routes? To answer these questions, we used a web-based data platform Replica®. This platform utilizes GPS-based data from smartphones and vehicle computers to understand who travels on roadway segments and for what purpose. For this initiative, data was filtered only to report the following:
• Trips by Calaveras County Residents
• Starting at their home location
• Traveling a distance greater than 65 miles
With these data filters, the platform highlighted exit routes and the percentage of vehicles on each road.

Calaveras County has a considerable number of part-time residents and vacation homes; however, this information was not able to be modeled or filtered using Replica®. The reader is cautioned that this data platform uses a combination of actual data and algorithms to create a travel pattern model. These models can provide less-than-perfect vehicle counts, but they provide highly reliable percentages. Therefore, the data in the tables below are shown as percentages. This model run utilized an average Thursday in the Fall of 2021. The model cannot be run to pinpoint a specific event day, so the trips presented reflect the travel patterns under non-emergency conditions.

Priority Corridors
3 Figure 1: Routes of Hwy 4 Up-Country Residents Leaving the County While Calaveras County has just one incorporated City, it has many Census-Designated Places (CDPs).

CDPs are statistical geographic entities representing closely settled, unincorporated communities locally recognized and identified by name. They are the statistical equivalents of incorporated cities but lack legally defined boundaries and governmental structure administered by elected officials. CDPs are areas with a population concentration with a locally recognized name. Figure 2 shows the CDPs within Calaveras County and the comparative populations of each.

Interestingly the model illuminated several County Maintained roads that are used as more direct routes through and out of the County. Therefore, each local roadway exiting CDPs was evaluated, and the percentage of traffic carried was reported. As a result, these local roads should be given priority in future evacuation plans.

2.1 Priority Exit Routes
Four two-lane state highways and three local roads serve Calaveras County and provide exit routes. The state highways are State Route (SR) SR-4, SR-49, SR-12, and SR-26, and the local roads are O'Byrnes Ferry Road, Parrotts Ferry Road, Milton Road and Burson Road. State Routes 4, 12, and 26 run eastwest, with SR-4 being the only route to exit the County's eastern boundary. SR-12, 26, and 4 exit the County's southern border. SR-49 is the only north-south running route. However, SR-26, which generally runs east-west, turns north at its eastern end, crossing the county boundary 12 miles east of the SR-49 county exit. Altogether these routes provide ten entrances and exits from the County. The state highways are maintained by Caltrans, which staffs four maintenance facilities throughout the County. These facilities are in Angels Camp (SR-49), West Point (SR-26), Camp Connell (SR-4), and Cabbage Patch (SR-4, winter only). The County Public Works Department maintains the local roads.

In addition to the priority exit routes, it is important to note the westside, north/south connection corridor, Burson Road, from Comanche Parkway to Milton Road for State Routes, SR-4, 26, 12, and 88. This connection is crucial and allows emergency response teams an alternative route, avoiding bottlenecks and road closures on the State Routes.

Table 1 presents the roadways residents use to leave the County. For this analysis, the whole County was selected as the trip origin, and surrounding counties were selected as destinations. Table 2 below isolates each community to understand community-specific preferred exit routes better. For this analysis, the distance traveled by residents when leaving the County was Priority Corridors

*AADT: Annual Average Daily Traffic
**Average percentages of residents utilizing each route for trips longer than 15, 30, 45, or 60 miles.

The data above in Table 1 were filtered by the following:
• Trips by Calaveras County Residents;
• Trips that start from Calaveras County;
• Trips that conclude in counties other than Calaveras County; and • Traveling a distance greater than 15, 30, 45, and 60 miles.

Table 1 summarizes results from the Replica® model for the eleven roadways that can be used to exit the County. To adequately capture data that is representative of the County, the model was run for four different scenarios with travelling distances set at 15, 30, 45, and 60 miles, respectively. The purpose of running the model with varying travelling distances was to make certain all residents were included - from those who live close to the County border i.e, West Point, and residents who live further from the County Priority Corridors
6 border, i.e, centralized communities. To conclude the results, an average percentage from the various traveling distances was determined.

The data run reveals that for residents traveling 15 miles or more to leave the County, 21% of residents use SR-12, 17% of residents use both SR-49 (north) and SR-26 (south west) and 12% of residents use SR-4 (west). Each of the remaining corridors are all utilized less than 10% for residents leaving the County.

Results for residents traveling 60 miles or more to leave the County indicates that SR-4 (west) is utilized the most with 36% of residents using the route. 28% and 13% utilize SR- 12 (west) and SR-26 (southwest), respectively. Less than 10% of residents utilize each of the remaining routes.

The average percentage from all travel distances revealed SR-12 (west) being the most used corridor with 27% of residents choosing the route as a county exit. SR-4 (west), SR-26 (southwest) and SR-49 (north) had average percentages of 25%, 16% and 10%, respectively. The SR-12 route provides the shortest path to Sacramento, while both SR-26 and SR-4 lead to Stockton. SR-49 serves as a primary connector for the respective State Routes. All four roadways offer access to SR-99 and Interstate-5 (I-5), both regionally significant north-south freeways used to access California's central Valley. SR-4 ultimately connects to the San Francisco Bay Area.

Once the County resident's exit road preferences were understood, the model was refined to understand the exit routes for each populated area. Residents rely on state highways as the primary routes through the County. However, several small towns in the northern and central portions of the County rely on County maintained roads to access the state highway system.

Table 2 shows the preferred exit roads for each community and the percentage of residents that use each. Similar to the limited roadway options for residents in the center of the County, the SR-4 corridor north of Vallecito provides access to one of the largest population groups. Unfortunately, this corridor has few alternate roadways and similarly will require special considerations for evacuation.

The data above in Table 2 were filtered by the following:
• Trips by Calaveras County Residents;
• Trips that start from each community based on block groups; • Trips that conclude in counties other than Calaveras County; and • Traveling a distance greater than 30 miles.

2.2 Priority Local Roads
State-maintained highways pass through most population centers in Calaveras County. While having a highway double as a Main Street has disadvantages, the trade-off occurs with improved access. Caltrans maintains high-quality roads through evolving design criteria and continuous investment. However, the County does not have access to the same resources, so County roads do not evolve at the same pace.

Priority Corridors
8 As shown in Figure 2 and confirmed with Table 2, several Calaveras County Communities do not benefit from direct access to a state highway. These communities are Mountain Ranch, Sheep Ranch, and Rail Road Flat. Therefore, these communities will require special consideration while developing an Evacuation Plan.

An interesting observation from this community-focused model run is that residents on the north-to-south running routes of SR-4 and SR-12/SR-26 use the connection of SR-49 between San Andreas and Angels Camp to cross to the other north-south route. While SR-4 is the most heavily used exit point, SR-49 between San Andreas and Angels Camp is the most heavily traveled east-west roadway segment.

Therefore, this roadway segment also merits careful consideration for evacuation.

Most Calaveras County communities have less than four viable exit routes. And even the communities with more than two exit routes rely heavily on one or two primary roadways, with the third used by singledigit percentages of the population.

In addition to State Highways, several two-lane local roads are used as parallel routes, bypasses, and arterial roadways. Table 3 identifies key local roads, their direction, and the communities they serve.

9 3. Community Outreach Survey Data
To fully understand the evacuation needs of
Calaveras County and supplement the
stakeholder interviews, online surveys were
prepared for three different focus groups:

Community, First Responders, and Critical
Facilities. These interactive online surveys were
available for two months. The community was
asked to take the survey through a variety of
outreach methods, including:
• Email with survey links provided to the
project stakeholders.
• Direct email to each stakeholder
• Targeted emails to representatives of
community groups and facilities
• Through outreach materials handed out at a
widely attended Angels Camp Farmers
Market
• Links provided on the project website
• Calaveras Council of Governments (CCOG)
Facebook posts and on the CCOG August
Meeting Agenda
A unique aspect of the selected survey platform
is the ability for survey takers to share the
survey link on various social media platforms,
expanding the survey reach.

Each survey consisted of five screens, the first being the welcome and introduction and the last being the wrap-up. The second screen asked a series of questions in a standard survey format. After the questions screen, each survey had an interactive screen that presented options to help identify priorities. For example, the Community Concerns Survey asked survey takers to rank the types of natural disaster events that concern them most, while the First Responders Survey asked about agency preparedness.

The fourth slide was also interactive, providing a google earth map that survey takers could zoom in and out of and navigate to specific areas of concern. Once the location had been reached, survey takers could drop markers on the map and tell us more about why they identified that location. As seen from the Map Markers Results screen, figure 3 shows survey takers placed pins all over the map and for all communities indicating the broad reach of the survey. The map screen alone collected three hundred and nine pins. Of those, ninety-seven identified the locations of Traffic Bottlenecks, eighty-three pointed out narrow roadways, seventeen identified flooding issues, and forty-nine other pins were placed with associated user comments. A summary of all comments is provided at the end of this report.

In general, the comments received mirrored the sentiments from the in-person interviews. Below are the key survey results, following images of each of the three surveys.

Figure 3: MetroQuest Map Markers Results
Priority Corridors
10 3.1 Disaster Event Concerns
As seen in Figure 4, Wildfire, Extreme
Winter Storms, and Extreme Drought were
the top three natural disasters that
concerned residents the most, followed
closely by Extreme Heat.

Of these concerns, wildfires are the only
disaster that appears unexpectedly,
minimizing the time residents have to
evacuate. While all events are cause for
serious concern, most comments received
related to the County's roadways and
capacity to accommodate sudden
significant evacuations due to wildfire
events.

3.2 Modes of Transportation
When asked about the type of
transportation residents relied on, the
overwhelming majority relied on private
passenger vehicles for transportation, with
just one survey taker relying on public transportation. Informal discussions with residents during an inperson event highlighted several types of facilities where residents cannot drive and would require commercial vehicles for transport. The facilities mentioned were primarily resident care homes and senior living facilities. In addition, transportation would need to be determined for the local hospital and correction facility. While Hospitals and correctional facilities have unique needs that need to be considered in individualized evacuation plans, Calaveras transit (Calaveras Connect) has vehicles that can assist with targeted residential evacuations. Including Calaveras Connect as an option in residential evacuations has the added benefit of reducing the number of single-occupancy vehicles on the roadway network during evacuation events. Early coordination with transit should be considered in care facilities' evacuation plans.

3.3 Local Roads of Concern
All three surveys asked which roads were the
highest priority to be maintained for evacuations
and access. Figure 5 shows the results of this
question. Interestingly, the top four results mirror
the results presented in section 1. However,
other local roads were identified by a large
number of survey takers as high-priority roads.

This discrepancy is because while the other
roads do not carry much traffic, they are the only
routes available to communities with no highway
access. Therefore, the roads serving the
communities of Sheep Ranch, Mountain Ranch,
and Railroad Flat merit special consideration in
developing a county-wide evacuation plan.

The other local roads of concern identified in
figure 5 are listed in Table 4 below.

3.4 Emergency Event Notification
Finding Information:

Across the three surveys, a typical
response was that residents don't know
where to go for information or where to
evacuate.

Residents responded that 28% use
Calaveras County OES Alert for
Emergency Notifications, followed by 19%
using various Facebook Groups for
emergency information. Additional sources
include MyMotherlode.com, fire.ca.gov
(CalFire), and PineTree.net. Around
twenty different platforms were identified
where residents looked for information
during emergencies. These sources are
listed in Table 5.

Several residents commented that they get
their information only from neighbors, with
one stating that "my granddaughter's
parents will call." And one resident said they have no way of knowing about evacuation events.

The First Responders groups stated that they get their information from the following platforms: OES Alerts, the Cal Fire Website, Calaveras Alert, ECC, Radio dispatch, phone, reports, community, Angels Fire, CCSO, dispatch centers, Emergency Command Center, Emergency Command Center TCU, and the Calaveras County Sheriff Office.

12 Notifying Others:

The First Responders and Critical Facilities groups
were asked how they notified people about the need
to evacuate: The response was predominantly Text
Notifications, with a few responding that they alerted
people by email, phone calls, or in-person
notifications. There was not a dominant form of
notification identified. There was a strong consensus
among survey takers that residents do not know what
to do or where to go during an evacuation event.

Figures 7, 8, and 9 convey the First Responders and
Critical Facilities' feedback about how their residents will respond during an evacuation event. On a scale
of one to five, with five being the best, both surveyed groups responded that Calaveras County residents
are not well notified during an event, do not know
what to do, and do not know where to go. While out
of the scope of this initiative, a well-publicized and
utilized resident notification platform is
recommended.

An excellent suggestion through the first responder's
survey was creating an alert system for Air B&B's, and better yet, a geofenced alert system that would push alerts to anyone with a cell phone within a certain area. An alert system cannot rely on cell phones alone because many areas have poor or no cell phone service.

13 3.5 Challenges Preparing for and Responding to Evacuations Challenges Preparing:

Of the First Responders and Critical Facilities surveyed, 71% had an operational evacuation plan, and one is working on a plan. Two do not have evacuation plans and are not currently developing them. Of the agencies that had developed plans, the plans were developed in coordination with other agencies.

Both groups were asked what they saw as the biggest challenges in preparing for and responding to evacuations. Survey takers were allowed to check all that applied. Resident preparation before an event and knowledge of what to do during an event were common responses, along with funding challenges, staff, and resources.

15 Most Challenging Roads for Evacuations:

When the First Responders were asked their opinion of the functionality of the Counties Evacuation Routes, the
majority response was two stars on a scale of one to five, with five being the highest score. This ranking indicates that the Counties evacuation routes' functionality needs improvement. The following technical memorandum of this initiative will provide options for evacuation route
improvement. Please see figure 14 for the functionality ranking.

Not surprisingly, when the First Responders and Critical Facilities were asked which roadways present the most
significant challenges to evacuation operations, the
responses mirrored that of the general public's reactions.

Figure 18 shows that State Route 4 was overwhelmingly
identified as the route that posed the most significant difficulty for evacuation events. This response supports the data in section 2, indicating that State Route 4 is the most heavily utilized exit route for traffic leaving Calaveras County.

16 3.6 First Responders Evacuation Preparedness
While the Evacuation Routes and Resident Communication were identified as areas that need improvement, the First Responders indicated that they are generally well-trained for Evacuation Events, with no one start responses and some five start responses to this question. Interestingly, when presented with a variation of this question, changing the word “training” to “preparation” the positive response decreased with a portion of the group giving one star to the preparation question, and no one responded with five stars. These responses indicate that the First Responders feel well-trained but not fully prepared for an evacuation event. Please see figures 16 and 17 for the specific rankings.

3.7 Map Markers and Written Comments
As discussed above, all three surveys included an opportunity for survey takers to drop markers on a map and add comments about why the marker was dropped. Pre-set markers included: Traffic Bottlenecks, Narrow Roadway, Flooding, One Way In/One Way Out, and Other. The First Responders Survey also had a marker for Road Not Accessible To Us. The listing of markers, their locations, and any additional comments are provided in Appendix 1

4. Projects to Mitigate Risks Along the Priority Corridors Hazard Mitigation projects can be divided into three categories. The first is major infrastructure improvements, typically costing several million dollars and taking several years to develop. The second is minor infrastructure projects, generally costing less than a million dollars, that can be implemented within a year or as ongoing maintenance. And the last is planning projects that can be used to prioritize a program of projects or to develop strategies to manage potential emergency events.

17 The following project recommendations were developed using the Hazard Risk and Vulnerability Assessment, Stakeholder Interviews, and Community Outreach.

4.1 Major Infrastructure Improvements
Combining the community outreach and traffic data platform reveals the three highest-use roadway segments in the County. These segments are listed in order of highest volume:

1. Highway 4 from Angels Camp toward Stockton

2. Highway 49 from Angels Camp to Highway 12 in San Andreas

3. Highway 4 from Angels Camp east to Arnold
The first segment experiences the volume of residential traffic exiting the County due to the large population centers along the Hwy-4 corridor. The second most used roadway segment for residential traffic leaving the County is Hwy-49 between Angels Camp and San Andreas because it is the only northsouth highway across the County. And the third highest volume roadway segment for residential traffic leaving the County is the Hwy-4 corridor Northeast of Angels Camp.

While few alternative routes exist, if Hwy-4 is blocked, Highways 12 and 26 could be used to exit the County to the Central Valley. Similarly, Pool Station Road could be an alternate route to Hwy-49; however, Pool Station Road is a narrow two-lane road not recommended for large vehicles and cannot be used by all highway traffic. Additionally, Parrotts Ferry is used as an alternative route to Highway 49 when events or congestion occur at the Fairgrounds. No alternate routes exist for Hwy-4 east of Angels Camp; however, segments of County maintained roads, such as Murphys Grade Road and Moran Road, can provide bypasses for segments of Highway 4
In general, the Caltrans-maintained highways provide the most reliable evacuation routes. Conveniently these highways pass through the major population centers. While a network of County maintained roads connects the smaller population centers, these roads should be used as evacuation routes only for the small number of residents that live along them.

Major Infrastructure Improvement Projects Include:
• Completion of all phases of the Hwy-4 Wagon Trail project • Shoulder widening on Hwy-49 between Angels Camp and San Andreas (Hwy-12 intersection) • Defensible Space Clearing along Hwy 4 and Hwy 49
• Hazard Tree Removal along Hwy 4 and Hwy 49
• Replacement of all medium and high-risk bridges
• State Route 49 Mobility Project – Addition of roundabouts and traffic signals at the Highway 4/Highway 49 intersection in Angels Camp

4.2 Minor Infrastructure Improvements
Major themes revealed during outreach were requests for roadside defensible space clearing and drainage improvements. If sufficient funding is identified for a County Wide annual Defensible Space Clearing program, this project can be moved to the Major Infrastructure Improvements. More realistically, roadside defensible space clearing on County and City Maintained Roadways will become part of the roadway maintenance program. Similarly, roadside ditch clearing, grading, and culvert replacement could become part of the prioritized maintenance plan of the County and Angels Camp.

A second online survey is circulating to prompt residents and stakeholders to provide specific locations for targeted maintenance activities. This list will be provided in the final report.

Major Infrastructure Improvement Projects Include:
• Defensible Space Clearing – Prioritized Annual Maintenance Program • Roadside Ditch Clearing and Grading – Prioritized Annual Maintenance Program • Culvert Clearing/Replacement – Prioritized Annual Maintenance Program • Roadside slope evaluation with erosion control / slope stabilization - Prioritized Annual Maintenance Program
Priority Corridors
18 4.3 Planning Projects
While the County has a few privately developed evacuation plans, a unified plan does not yet exist. Key challenges discovered with this initiative include residents' inconsistent use of communication platforms.

After completing this Evacuation Needs Assessment and Preparedness Plan, the next step is developing a County-wide Evacuation Plan. This plan would identify evacuation routes, shelter locations, communication platforms, interagency partnerships, and ongoing training. For example, Caltrans regularly runs dam failure emergency response training and would be a great partner for emergency response scenario training.

Community outreach is a significant component of a County-wide Evacuation Plan to ensure that all community members are aware of the plan and are regularly reminded about what to do in an evacuation event.

Planning Projects Include:
• County-Wide Evacuation Plan
• Unified Notification System that can reach all residents (including those out of cell phone range) • Annual Training Program for First responders and community leaders.

5. Conclusions
Because most of the population in Calaveras County lives in communities accessed by Caltrans highways, the highest priority evacuation routes are state highways. Highway 4 and Highway 49 (between Angels Camp and San Andreas) are the two routes used by most residents leaving the County. Future investments to protect residents during emergency events should be prioritized along these two corridors.

In addition to large Infrastructure projects, prioritized annual maintenance programs are recommended to support communities not served by a highway and along routes that can provide parallel capacity or bypasses for the highways. In addition to infrastructure projects, additional planning work can help residents and first responders understand what to do during emergency evacuation events. The final report for this initiative will include additional information about these projects.

Comment Response
1 page 75 Disagree "Greenhorn Road", if the referring to Grennhorn Resort, Angels Camp. Generally flat wide roadways build based on the most current requirements. The highest income, highest home value resort also has additional exit roadway via Finnegan Lane.

Thank you for your comment. At this time, the public does not have a legal right to access Finnegan Lane from Greenhorn Creek Road. The informal access crosses a privately held parcel, and access can be legally blocked at any time by the property owner.
2 I was evacuated three (3) times from Arnold & Murphys during 1991 to 2007. never suffered property damage but the exit routes were Highway 4 ONLY, either up or down the mountain - no other way! The main problem, I think, is the lack of access roads. In addition, the lack of fire safe engfrocement by authorities abd negligence by property owners creates the dangers. Forest acccess roads that exist are not cleared on either side so become unusable when needed.

Having dry underbrush anywhere is invitation to fires. Removal of the underbrush and dead trees should be a yeararound job for the entire forest, State and Federal. Fire PREVENTION should be emphasized instead Fire FIGHTING! Thank you for providing feedback on the Draft Evacuation and Access Needs Assessment and Preparedness Plan. In the plan, a lack of access roads, especially for the vulnerable communities located in dense vegetation areas, such as the central and more eastern zones were identified, as you said. As a result, Routine defensible space clearing was chosen as a priority project to help better prepare the county for future events. Continuous funding opportunities are being sought out. Ideally, annual defensible space clearing and clean-up maintenance programs will be in place. In the meantime, please stay on the lookout for the Evacuation Plan project updates, as community feedback will be an important part in developing an effective plan.
3 Thank you for doing this. Please keep me informed. Thank you for providing feedback on the Draft Evacuation and Access Needs Assessment and Preparedness Plan. Please stay on the lookout for project updates, as community feedback will be important in developing future plans and projects.
4 Excellent, detailed Evacuation and Access Needs & Assessment Preparedness Plan! Thank you for your public outreach meetings and fact-gathering, maps and data needs assessment. Calaveras County needs road and bridge improvements, a countywide Evacuation Plan, education, and a Unified Notification system, Thank you very much! Thank you for providing feedback on the Draft Evacuation and Access Needs Assessment and Preparedness Plan. Please stay on the lookout for project updates, as community feedback will be important in developing future plans and projects.
5 Will the stop light on Hwy 4 in Murphys be disabled? This needs to NOT be working in order to facilitate traffic moving continuously through Murphys. CHP/Sheriff needs to direct traffic at that intersection rather than the stop light working. When we evacuated for the Camp Fire it took hours to get down the hill from Arnold due to that light working as usual. A flashing yellow would be fine, but no red light whatsoever.

Thank you for providing feedback on the Draft Evacuation and Access Needs Assessment and Preparedness Plan. At this time, no precise procedures have been developed but will be during the making of the county-wide Evacuation Plan.

During the design of the Evacuation Plan, various traffic analyses will be looked at for all possible evacuation scenarios.

One of the evacuation techniques we've discovered to be successful through research is just what you described, allowing traffic to flow freely and relieving congestion. It is input like yours that will help us implement an effective Evacuation Plan. Please stay on the lookout for project updates, as community feedback will be an important part. 6 I would like to bring the following to your attention: Important as it is to make sure escape routes on the larger highways in this county are ready for an emergency, I would like to point out that it is equally important for citizens of this county to reach these major roads. I live in a small Homeowners Association (Murray Creek ranch HOA, 23 parcels) off Gold Strike Rd just outside of San Andreas. Wr has had a recent arrival in this HOA, who went to the County Building Department resenting falsified surveyor documents, that allowed for building on an HOA easement of a fire escape route. The Building Department could not be bothered to check the actual records and gave permits for a well and the building to this property owner to build and block the escape route. At this point, the HOA cannot use this escape route, because we have a well and building foundations obstructing our emergency route. The owner of this property has also living for months now in a trailer parked on this easement. The HOA has tried several times to rectify this situation, but the County's Building Department is uncooperative. The point I am making here is, that if the county does not do its due diligence when it comes to building on a "so-called" abandoned easement, then what are we to expect from this county in terms of emergency response? Never mind that they will not enforce their rules about living in a trailer without any toilet facilities right next to a creek. I believe that a large part of the emergency response in this county should be placed on smaller roads as well, How many of us live right next to Hwys 4,12,49 and 26? What is the distance most of us have to travel to reach those big roads? I think that there us a big piece missing in this emergency escape plan and it is called small access roads. Enforcing existing emergency response escape easements seems so basic. But this county will not even do that.

Thank you for your comment.

Calaveras Access Needs Assessment and Preparedness Plan Community Comments and Responses Appendix H
7 We can't afford the cost of doing nothing." This statement sums up the totality of this report and plan….and also what needs to be done to finalize and implement a Greenhouse Gas Reduction Plan and implement the new General Plan.

This county has avoided spending and planning for as long as I have lived here. It will take years and years to catch up and the county needs to make all of these things a priority NOW.

Thank you for providing feedback on the Draft Evacuation and Access Needs Assessment and Preparedness Plan. Please stay on the lookout for project updates, as community feedback will be important in developing the next phase of this initiative, the County Wide Evacuation Plan.
8 My current concerns are regarding the proposed roundabouts in Angels Camp. I see those as being a liability in any evacuation emergency. The amount of traffic will also make it difficult and confusing for some of us who are senior citizens as well as people who need to cross at that point. For instance, my son is in a wheelchair and a roundabout can be extremely dangerous.

Thank you for your comment.
9 Only today did I come across the Plan Draft quite by accident. In general, I think all public agencies in Calaveras need a better way(s) to notify public about projects and specifically when ' community input' is being sought. And we as community members, of course, need to figure out how to keep a finger on pulse of the myriad projects, development plans, etc. going on in our county. That being said, I think the "Priority Corridors and Key Considerations" Dewberry Report was well documented and captured the gist of the community concerns. I pray it doesn't take years for county agencies to take action to address the highest concerns. I skimmed a couple of the other appendices, it should be noted THERE IS NO "Copper Cove High School" and it should be removed from your list as a "Potential Shelter" location! Thank you for the opportunity to participate.

We appreciate your feedback and apologize that you only came across the plan, accidentally. We're always looking for suggestions from residents regarding where they get their information and specific channels they may use. One of our main priorities for this initiative is figuring out what works best for people; it's crucial to hear back from residents, like you! Is there a specific platform you use to receive information? We're always open to posting more places. Regarding Copper Cove High School, you are right! The school apparently closed in 2006. In the final plan, Copper Cove High School is removed as a potential shelter location.
10 Please consider Little John Rd in Copperopolis as a vital evacuation route. This road is now at emergency evacuation capacity with the release of the new Copper Valley (CV) neighborhood two years ago. Former Planning Director Peter Mauer said this additional new neighborhood will put Litttle John Rd at its maximum capacity for emergency evacuations. Copperopolis fire district and CalFire need to be more liligent when reviwing these plans. In the case of the new CV neighborhood, Copperopolis Fire didn't address emergency evacuation on Little John Rd. CalFire didn't respond at all! Any new development in this area should be severly restricted until more viable emergency evacuation routes are developed.

Thank you for providing feedback on the Draft Evacuation and Access Needs Assessment and Preparedness Plan. Please stay on the lookout for project updates, as community feedback will be important in developing the next phase of this initiative, the County Wide Evacuation Plan.
11 The letter by Megan Fiske in the West Point News reached me after August 31. I'm currently chairing the recently reconstituted Blue Mountain Emergency Preparedness Committee (BMEPC) in the West Point / Wilseyville area. The two main types of scenarios that concern us here are (1) wildfire and evacuation and (2) extreme winter storm impacts that disable the road network, grid, and other lifeline services. Soon I will take the time to look carefully at your online materials. Meanwhile, I want to reach out, make contact, and ask that you loop us into your communications, expecially regarding activities and events. At some point we could talk, and our committee could enjoy a conversation.

So far we've organized one town hall with the county, on wildfire; more are possible, and workshops are planned.

Good wishes -- Rick
Thank you for your comment. Now that the needs assessment is complete, the next step will be to develop a County Wide Evacuation Plan. This next step will not be possible without the input and collaboration with community organizations such as your group. We look forward to the next phase of this important work. 12 Flooding hazards in lower sections of Calaveras County (La Contenta and Rancho Calaveras saw flooding) need to be reflected in Report.

All of the locations where the 100 year flood plain crossed a road, are included in the report (page 92) which is included as a larger attachment and full project list in Appendix B. Additionally the local flooding problem locations are called out on the MetroQuest Pins slide on pages 38 and 40 Also detailed in Appendix G. and Finally, we added additional projects to the Zone D (Valley Springs area) project list included in Appendix B. 13 People were going down Burson Rd and cutting across Olive Orchard Rd because they were cut-off on Hwy 12 and at Gold Course and on Cosgrove Creek by the Zippy Mart due to flooding.

These locations have been identified as recommended Zone D projects. This information will be used to develop evacuation zones in the next phase of this initiative, the formal evacuation plan. 14 2 Seperate emergency evacuations at Mobile Home Park (Winter of 2023/23) and Valley Springs Proper was on Notice. Yes, the flooding issues in 22/23 and 23/24 were identified in the report. 15 Include local roads because this is what locals will use when evacuation because they know them. Agreed. 16 Widening is a good consideration Agreed.
17 Highlight the fire hazards, lots of dry brush will result from heavy rains throughout lower sections of the County. Potential project added for Zone D: Roadside grass mowing 18 Need to identify best evacuation routes (including local roads) and make the information readiliy and easily accessible to public to utilize in emergency.

Thank you for your comment. Specific evacuation routes will be further identified in the next phase and during the development of the County WIde Evacuation Plan.

Design new commercial and industrial development to be compatible with the natural, scenic, and cultural resources and rural character of Angels Camp (commercial community character and design is addressed through proposed code amendments addressing storage containers, excessive slopes)

BACKGROUND
The Planning Commission recommended to the City Council approval of the proposed code changes at its September 14, 2023, meeting. On September 19, 2023, the City Council introduced the ordinance, waived the first reading and set October 3, 2023, for a second reading. On October 3, 2023, the City Council took public input and referred the proposed code changes to the City Attorney for review. The City Attorney is currently completing that review. Continuing the item to a date certain at the October 17, 2023, meeting allows the City to forego the cost of resubmitting a new legal notice for the item.

The City received a Local Early Action Planning (LEAP) Grant to update various sections of the City Code including those related to housing, design standards and permit streamlining. In conducting a review of the city codes for design standards and permit streamlining, staff also identified uses that have not been addressed, were addressed insufficiently, have resulted in multiple code violations, or are included in multiple code sections with conflicting regulations. To resolve these issues, in conjunction with undertaking LEAP code amendments, multiple code changes are proposed and summarized as follows:

Table 1: Purpose(s) of proposed code changes
Proposed code change Reason for Code Change
Mobile food vendors, temporary and seasonal
sales stands
Public health and safety, code violations, eliminate
conflicting code sections, clarification
Certificates of occupancy Housing standard (LEAP), Public health and safety, code violations
