Executive Summary
The purpose of the Hoopa Valley Tribe’s Multi-Hazard Mitigation Plan (MHMP) is to
guide current and future efforts effectively and efficiently, to mitigate natural,
technological and human caused hazards on the Hoopa Valley Indian Reservation
(HVIR). HVIR, in coordination with other agencies and governments as appropriate,
mitigate and respond to hazards that may generate off the Reservation and cross over
Reservation boundaries. The overall goal is to reduce or eliminate long-term risk to life
and property from various hazards.
Natural hazards such as floods, wild land fires, earthquakes, and severe winter storms
pose a significant threat to the natural resources, political integrity, economic stability,
health and well-being of the community members on all levels of the HVIR. The lack of
planning and preparation for those hazards could potentially increase the frequency and
severity of those hazards if left unregulated. The Office of Emergency Services led the
development and the Hoopa Tribal Local Planning Committee (LEPC) effectively served
as the Mitigation Planning Team. Sophi Beym, independent contractor, served as final
editor and assisted with the submission of the final plan.
The Office of Emergency Services will lead the implementation of the MHMP, will
secure funding for future community planning and develop grants to sustain the
mitigation actions within the plan. The Local Emergency Planning Committee (LEPC)
was developed as a government and community based organizations to be the Tribal
Emergency Response Committee (TERC) and fulfill the requirements of an LEPC as
well.
The original version of the MHMP was meant to be a living document. Once the original
document was approved and implemented by the Hoopa Valley Tribe, pre October 2008
before 201.7. The original document is in accordance with §201.4 1(c)(6) through Tribal
Resolution #09-233. As such the Hoopa Valley Tribe would ensure accordance with 44
CFR §13.11(c) and 44 CFR §13.11(d) with respects to periods for which it receives grant

In October 2008, Section 201.4 was replaced with 201.7 Tribal Mitigation Plans.
12
funding through FEMA. Below is the prerequisite 44 CFR §201.4 2(c)(7), providing the
requirements for a Standard State-Level Mitigation Plan:
The Hoopa Valley Tribe will comply with all applicable Federal statutes and regulations:
and in addition, the tribe will amend this Plan to reflect new or revised Federal
regulations or statutes, or changes in Tribal Law, organization, policy, or tribal
government operations. Such amendments will be added to the Plan as they are
developed and deemed applicable.
The Hoopa Valley Tribe has endured many events that have tasked the abilities of tribal
resources to respond to, mitigate, and recover from incidents such as flooding, severe
damage from storms, wildfires, and public health threats. A severe winter storm at the
end of 2005 through the New Year of 2006 caused an estimated $1.5 million dollars in
damage. Flood stage warnings were in effect for several days despite peaking
approximately 3 feet under the flood stage level. In 1999 the tribe found itself immersed
in smoke from wildfires that started off the reservation and burned onto Hoopa, creating a
public health incident from the effects of the long-term exposure to the smoke. Similarly,
the Hoopa Tribe once again found itself inundated and immersed in smoke in 2008 from
wildfires outside the boundary of the reservation. In 2007 and 2008, the Hoopa Tribe
evoked the Hoopa Tribes, Emergency Operation Plan (EOP), and was successful in
setting in place an Incident Management Organization, which dealt with the response,
mitigation, and recovery efforts of the 2007 Severe Storm Event and 2008 Air
Quality/Public Health Threat affecting the health and welfare of the community of
Hoopa. The Hoopa Valley Indian Tribe defines public as the community of Hoopa,
visitors of Hoopa, human beings on Hoopa. With the continued development of the 2011
MHMP Update and long-term infrastructure training and development, the Hoopa Tribe
will systematically identify policies, actions, and tools for maintenance for any type of
emergency or disaster.

In October 2008, 201.4 was replaced with 201.7 Tribal Mitigation Plan.

Chapter 2 describes the existing hazard conditions of the Hoopa Valley Indian
Reservation, as well as the current infrastructure, resources, and use patterns, as well as
attitudes and expectations. The Reservation has faced, and continues to face the threat
from several natural hazards. Among these discussed in the Risk Assessment found in
Chapter 3 are; dam failure, earthquakes, droughts, floods, severe storms, and wildfires.
The Tribe also faces threats from hazards such as chemical spills, arson, and other human
caused disasters. Since we live in a valley surrounded by conifer forests, we are subject to
unique dynamics that control the options we have in dealing with certain hazards. As
such, we have had to extensively research not only historical events, but potential threats
associated with living downstream from an earthen dam. Knowledge about these hazards
is a necessary element to the development of effective hazard mitigation strategies to
limit and/or prevent the loss of life and damage to structures and infrastructure.
Our Mitigation Strategy is the most critical portion of this document, as the Hoopa Tribe
attempts to evaluate every possible scenario that could result from a natural disaster or
potential risks outlined in Chapter 3.
Chapter 4 discusses the pre and post-disaster hazard management policies, programs, and
mitigation capabilities of the Hoopa Valley Tribe, as well as other regional jurisdictions
that provide support services to the Hoopa Valley Tribe during disasters impacting Hoopa
Valley Reservation. This discussion includes an evaluation of Hoopa Valley Tribe laws,
regulations, policies, and programs that are related to hazard mitigation, pre-disaster and
post-disaster laws and policies are addressed along with addressing new development
activities in hazard-prone areas. Funding capabilities for hazard mitigation projects are
also discussed.
Chapter 5 discusses the local and Tribal capability assessments including general
descriptions and analyses of mitigation policies, programs, and capabilities of local
organizations on the Reservation. Finally, the MPT prioritized the mitigation actions
based on precedence and funding to determine an action plan.
14
The Plan Maintenance Process is outlined in Chapter 6, and describes how the MHMP
will be monitored, evaluated, and maintained as a living document. The newer federal
hazard mitigation planning regulations (44 CFR 201.7) require revision every five years.
The MPT will review the mitigation plan annually. Federal regulations require a plan
maintenance process that includes an established method and schedule for monitoring,
evaluating, and updating the plan; a system for monitoring implementation of mitigation
measures and project closeouts; and a system for reviewing progress on identifying
projects, creating structural and non-structural projects, achieving mitigation goals as
well as specific activities and projects identified in this mitigation plan. Chapter 6
describes this process in detail.

Chapter 1 – Purpose and Need
Introduction
This 2011 update to the 2006 Hoopa Valley Tribal Multi-Hazard Mitigation Plan
(MHMP) has been prepared in accordance with 44 CFR 201.7 Tribal Mitigation Plans.
This plan is based on the Multi-Hazard Mitigation Planning Guidance of the Disaster
Mitigation Act of 2000 (P.L. 106-390), published by FEMA in 2004, revised in June
2007, November 2006 and June 2007 and the Tribal Multi-Hazard Mitigation Planning
Guidance in March 2010. This MHMP documents the coordination of planning efforts,
who was involved, public outreach, what tasks and resources were made available and
descriptions of the Hoopa Tribe’s existing resources and infrastructure, risks and hazard
assessments, and a mitigation strategy to prioritize risks and associated action plans.
The Federal Emergency Management Agency (FEMA) is the principal federal agency
with jurisdiction over the proposed updated mitigation plan. The Applicant for the
proposed updated plan is the Hoopa Valley Tribal Council (HVTC). The purpose of this
updated MHMP is to satisfy the requirements of FEMA as well as to document the needs
of the Hoopa Valley Tribe in regards to hazard planning preparedness. Beginning in
Federal Fiscal Year 07, all federal preparedness funding became conditioned upon full
compliance with the National Incident Management System (NIMS). Homeland Security
Presidential Directive (HSPD-5) was issued in 2003 and required all federal agencies to
use it in their individual domestic incident management and emergency prevention,
preparedness, response, recovery and mitigation programs and activities. The NIMS was
issued by the Department of Homeland Security (DHS) on March 1, 2004, to provide a
comprehensive and consistent national approach to all-hazard incident management at all
jurisdictional levels and across functional disciplines. In a September 8, 2004, letter to the
nation’s governors, DHS outlined a phased approach to NIMS implementation, with full
compliance required by September 30, 2006.
The goals of the Hoopa MHMP are to:
1. Reduce the threats to public health and safety posed by natural hazards;
16
2. Reduce infrastructure damages caused by natural hazards;
3. Reduce the environmental impacts of natural hazards, mitigation actions, and
future development activities;
4. Reduce the long-term costs resulting from natural hazards and their mitigation.
5. Mitigate threats of terrorist activities and illegal marijuana grows on Tribal lands
that result in health and safety impacts to humans and the watershed, including
sensitive wildlife and salmon species.
The objectives of the Hoopa MHMP are to:
1. Prevent future development areas of high risk or create ways to minimize risk;
2. Protect or alter existing hazardous areas;
3. Choose most cost effective way to deal with hazards and protect our Tribal
resources, which is in line with existing Tribal ordinances;
4. Develop a Cost Benefit analysis for all hazards and mitigation measures;
5. Redesign existing projects to be in compliance with MHMP;
6. Manage floodplains, rivers, streams, erosion, and slides to minimize impacts to
structures and the community;
7. Improve coordination between the Hoopa Valley Tribe and other local, state, and
Federal jurisdictions;
8. Increase public awareness through education, community meetings, and the media
in preparation for future hazards;
9. Improve warning systems for potential hazards.
10. Obtain support and secure Homeland Security and other federal funding for a
coordinated response from law enforcement to reduce and eradicate illegal
marijuana grows and the associated health, safety and environmental impacts.
In order to effectively respond to all natural hazards the MPT identifies all potential
hazards and areas of concern within the Hoopa Valley by conducting a thorough hazard
identification and risk assessment. To meet the goals and objectives outlined above, the
Hoopa Tribe must be prepared for the worst-case scenario. This includes upgrades to
existing medical facilities, adoption of a comprehensive Incident Command System with
properly trained personnel, comprehensive studies on seismic activity an fault line
17
locations, adoption of stricter uniform building codes and environmental monitoring,
valley wide warning systems, east and west side response/stockpile centers,
implementation of best management practices under the Forest Management Plan (FMP)
and associated Fuels Management Plan (revised and approved in 2008) for fuels
reduction, evacuation plans, and most importantly public outreach. Without public
outreach, any disaster has the potential to reach pandemonium. Also the Hoopa Tribe
needs to pursue funding either through the State, guaranteed Government-to-Government
agreements, grants, or even introduction of legislation for a Tribal portion of Homeland
Security funds. These funds can be used to bring infrastructure up to code, increase
protection for new development, staff training, public outreach, and critical equipment
necessary to carry out the goals and objectives of the Hoopa Tribal MHMP.
The Office of Emergency Services will serve as the lead tribal agency and conduct bimonthly meetings on the MHMP to discuss current issues and to implement projects and
activities conveying these matters to the HVTC. For the public, the OES will educate the
community on emergency preparedness through various measures, such as, implementing
a Mass Notification Warning Sirens System with educational outreach and disaster
preparedness drills to educate and encourage the community to prepare for disasters by
stocking extra supplies and keeping emergency survival kits, knowing family emergency
contact information and evacuation plans, and generally becoming more aware of all
hazard types. Public input will always be welcome as most people are aware of issues in
the community but, more importantly,
The LEPC, serving as the Mitigation Planning Team (MPT), recommends the
following action plans based on the development of this MHMP:
1. Establish a permanent all hazards emergency planning team evolved from the
LEPC from pertinent agencies and tribal departments; elect a chairperson, and
immediately identify infrastructure needs. This would be an advisory board to the
Chairman and Council, as well as a liaison between emergency services
departments;
18
2. Pursue permanent funding for building codes, infrastructure upgrades and
planning team efforts;
3. Approve this MHMP as a guiding document and ensure it is in line with existing
Tribal Codes and Ordinances;
4. Coordinate with other Tribal, Local, State and Federal agencies with interoperable
communications, and MOA’s where applicable, planning and emergency funding;
5. Review the existing Emergency Operation Plan and Hazardous Materials Plan and
amend where necessary to align and support the 2011 MHMP Update;
6. Review and amend existing models, maps and GIS coverage to be up to date with
current census and resource information of the Hoopa Tribe;
7. Implement a strong Public Education campaign in order to make the community
aware of potential hazards and how to respond to different situations. Also
8. Provide and maintain a current list of emergency contacts with numbers, cell
phones and e-mail addresses of pertinent employees of the Tribe.
To improve preparation for future hazard events, the HVTC has developed an Emergency
Operations
Plan
(EOP)
for
the
Hoopa
Valley
Tribe
(http://www.hoopansn.
gov/documents/TribalEOP.pdf). In addition, the Hoopa Tribe has developed a Hazardous
Materials Response Plan to guide the response to spills of hazardous materials on and
adjacent to the Reservation. Other documents pertinent to the guidance of this document
are the Hoopa Tribe’s Forest Management Plan (FMP), the Hoopa Tribal Water Quality
Control Plan (WQCP), the Hoopa Tribe’s Land Use Plan and Development Standards
(LUPDS), 1998 Draft Only - Integrated Resource Management Plan (IRMP), and the
revised and approved 2008 Hoopa Tribe’s Fuels Management Plan (FMP.
This MHMP provides detailed recommendations and an action plan designed to meet
each objective and, ultimately, the goals of the plan. The Hoopa Valley Tribal Council,
the governing body of the Hoopa Valley Tribe, originally passed Resolution No. 09-233
on December 3rd, 2009 and Resolution No.11-47 on November 21, 2011 to formally
adopt this updated plan.
19
This Hoopa Tribal MHMP is divided into seven Chapters:
•
Chapter 1 is this introduction, planning process and the purpose and need of the
Hoopa Tribal MHMP;
•
Chapter 2 describes the land use, socioeconomic conditions, and physical
characteristics of the Hoopa Indian Reservation;
•
Chapter 3 presents an assessment of hazard risks on the Hoopa Valley Indian
Reservation as well as a potential loss analysis;
•
Chapter 4 presents the Hoopa Tribe’s Mitigation Strategy;
•
Chapter 5 describes local mitigation planning coordination;
•
Chapter 6 describes the Hoopa Tribe’s MHMP maintenance process;
•
Chapter 7 summarizes this report.
The references cited in this plan and the acronyms and abbreviations used in this plan

Documentation of the Planning Process - §201.7(c)(1)
A Historic Perspective on the original development of the 2006 Multi-Hazard
Mitigation Plan
The core team members were invited to participate in 1- 2 or more planning meetings per
month from May through November 2011. Each meeting was facilitated by OES staff
who led the group planning process in determining Risk Assessment, Mitigation
Strategies, Funding Streams and Plan Maintenance. The beginnings of the MHMP
formed following the December 2005/January 2006 storm event experienced throughout
Northern California. Declaration of a state of emergency was issued by Humboldt
County, the State of California, and finally by the President of the United States for the
regions affected by that severe winter storm.
When the HVTC began assessing damage on the reservation, tribal officials contacted
federal and state agencies to determine what options were available to assist the Tribe
with disaster repairs. FEMA helped the Tribe start the process for site damage
evaluations and began educating tribal staff on the requirements for receiving FEMA
assistance. Most of the FEMA eligibility requirements for permanent assistance could be
met with existing tribal records and resources. However, the hazard mitigation plan
proved to be the one time-limiting factor because it would have to be constructed from a
variety of sources and made into a single cohesive plan. The Tribe’s staff, having
experience in developing broad policies to deal with a wide range of contingencies, began
drafting the MHMP with FEMA’s guidance and technical assistance beginning in
February 2006.
Preparation of the Original MHMP
The Tribe, with more than forty department managers, began assessing storm damage as
soon as January 3, 2006. In addition to documenting storm related damages, the
discussion encompassed the nature of the damages, the types of preventative measures
that could have been taken to prevent those same types of damage in the future, and the
process for recovery. On February 2, 2006, the hazard mitigation process began with a
conference call between the Tribe, department managers, FEMA, and the California’s
Office of Emergency Services (OES) because this was the first emergency the Tribe has
21
expedited since passing of the Disaster Mitigation Act of 2000. In addition to emergency
response and initial repairs, the Tribe is also required to begin a formalized mitigation
planning processes in order to be eligible for post disaster funding and repairs. While site
visits were being scheduled and damage assessments were being compiled, the Tribe sent
representatives to a FEMA applicants briefing in Eureka, CA on February 14, 2006 for
affected Humboldt and Del Norte entities. California OES and FEMA representatives
explained the recovery process and encouraged participation in all available recovery
programs. Indian tribes, as direct grantees, must submit an individual request for
assistance, which includes a FEMA-Tribal agreement and a mitigation plan.
On February 24, 2006, a hazard mitigation group was designated from the Tribe’s
emergency responders and essential services. The hazard mitigation group officially
formed under the Local Emergency Planning Committee (LEPC) and set about gathering
examples of successful mitigation plans from other tribes and cities for use in developing
the Hoopa Tribe’s plan. The Tribe held its annual General Meeting of the tribal
membership on March 4, 2006, and the Individual Assistance, Public Assistance, and
MHMP were topics for presentation and discussion. The LEPC incorporated comments
from the General Meeting into their planning process. In addition, previous occurrences
of certain types of hazards and disasters began to be verified and documented. The group
also began to chart the assets available to the Tribe in the event of a disaster through the
Office of Tribal Insurance. As the necessary information coalesced into usable
documents, each member of the group was delegated sections of the MHMP based on
technical expertise and logistical placement by department. The Tribe participated in
multi-agency collaboration at the Humboldt County OES on April 13, 2006, which
included US Bureau of Reclamation (USBOR), Central Valley Project (CVP), and
National Weather Service (NWS). The LEPC met with representatives from the KlamathTrinity Joint Unified School District (KTJUSD) and Hoopa’s downtown business
community. The group also met with cultural leaders on May 2, 2006.
22
Formation of the original Mitigation Planning Team (MPT) from the Local
Emergency Planning Committee (LEPC)
The MPT/LEPC members remain current with the exception of adding a few new
members to replace others who are no longer work for the Hoopa Valley Tribe or who
not directly involved with mitigation planning for their tribal department. Originally, the
core team of the MPT/LEPC solidified once responsibilities were assigned. The core
team met multiple times per month since March 2006 to gather the data necessary to
construct a hazard mitigation plan. The current LEPC member roster is shown in Table 1.

23
Hoopa Tribal Departments and community infrastructure continue to participate in HVT
MHMP goals, objectives and activities in actual all hazard incident disaster response and
threats in our local community and regional events. Hoopa department managers, other
than those listed as part of the core team, participated in the ongoing meetings, as their
respective expertise was needed. Those departments not called upon for their specific
expertise participated in the manager meetings called by the Tribal Chairman to discuss
mitigation planning progress. In addition, outside agencies (such as the KTJUSD) were
directly contacted to participate, including the Klamath Trinity Rural Community district
(KTRCD) to explore food sustainability. Efforts to reach the downtown business
community involved walking door to door. The core team made use of telephone, fax,
and email to reach interested parties. In addition, use of local media, KIDE 93.1FM radio
station and the Two Rivers Tribune Newspaper, helped spread information about the
ongoing mitigation planning efforts to the Hoopa community.
Coordination among Agencies - §201.4 3(b)
How Federal, State, and Tribal Agencies Participated
In early 2006, each tribal department was directed to make contact with all governmental
entities relevant to emergency preparedness, disaster planning, and recovery services.
Most tribal departments already have a gather data/generate report relationship with
outside funding agencies so outside participation frequently came through tribal
department channels. The Hoopa Valley Public Utilities District (HVPUD) and K’ima:w
Medical Center (KMC) are both operated by the Tribe, and the Hoopa Volunteer Fire
Department act under the auspices of the Tribe.
3
In October 2008, 201.4 was replaced with 201.7 Tribal Mitigation Plan.

How Other Interested Parties Participated
The Tribal Council directed all tribal departments to make disaster information available
in each of the respective offices. Many departments distributed and received damage
reports from a wide range of community members. Besides the overarching mandate to
all departments to assist with disaster and relief efforts, the LEPC held meetings open to
the public multiple times per month. In addition, meetings were scheduled to target other
interested parties in order to solicit their input for the hazard mitigation plan. See Table 3.

HVT Council Meeting Approval 2011 MHMP Update
Resolution
2011 MHMP Update
Participation by OEM-MPT/LEPC Members was represented over a (7) seven month
period from May through November 2011, by HVT Managers and Directors. The Hoopa
Tribal Forestry Department performed Geographic Information Systems (GIS) mapping
edits and update edits, including specific sections from other contributors in the Living
Resources Section. The Hoopa Fire Management Department contributed various update
edits, including the 2010 – 2011 Wildland Fire Analysis in Table 5. The Cultural Section
participated in the update with comments from members of the Hoopa Cultural
Committee. The Museum Curator updated this section by referencing locations of dance
sites that are intrinsic to our beliefs and are of extreme importance in connecting to our
ancestors/descendants and connecting the spiritual to ourselves. One or more of these
cultural sites are particularly vulnerable to erosion and must be protected and maintained.
Some Hoopa Tribal Departments had no changes, such as Hoopa Tribal Fisheries
Department, Hoopa Tribal Police Department, Hoopa Volunteer Fire Department, Hoopa
Tribal Environmental Protection Agency Geologist stated since the research and writing
of the Hazard Identification and Risk Assessment (HIRA) section of the Hoopa Valley
Tribe’s Multi-Hazard Mitigation Plan five (5) years ago in 2006, no new significant
information regarding the natural hazards covered in that section has been produced
which would warrant a rewrite of the Hazard Identification and Risk Assessment section.
A Community Disaster Preparedness Survey was distributed in August – October 2011 at
various community events and meetings, for the purposes of the community prioritizing
the greatest threat to least threat for all hazards preparedness and evaluating individual
and family disaster readiness. The Hoopa Community Emergency Preparedness Survey
provided a snap shot of our tribal community’s disaster preparedness knowledge and
readiness. There were 51 participants with, 32 females and 19 males who prioritized the
hazards to include:
•
#1 Wildfires – Highly Likely
•
#2 Dam Failure/Land Slides tied – Highly Likely
•
#3 Floods – Highly Likely
27
Approximately 50% of the survey participants were prepared for a disaster with resources
for survival and owned battery powered or solar radios for communication broadcasts.
Over 90% responded that they would be trained to help their neighbors and would
participate in a Citizen Emergency Response Team (CERT).
Over 90% of those
responding offered advice for mitigation projects that would make the community safer.
Meeting with Community Businesses
Due to a variety of personal and professional obligations, many of the Hoopa business
owners were unable to attend either of the two scheduled FEMA mitigation emergency
planning team meetings. So instead, members of the MPT/LEPC conducted door-to-door
visits with the businesses, distributing a brief survey at each site. They also took the
opportunity to discuss disaster preparedness with some of the local business owners and
their key staff. From the surveys and visit responses, the following summarized
documented information added to the MHMP.
•
Businesses in the Hoopa area both rent and own in roughly equal numbers. The
highest reported value of a business-owned building is $200,000, with some not
reporting a number. No one addressed the value of the property, but presumably
the building value includes the contents as well. The highest reported approximate
content value was $100,000 and the lowest reported was $8,000.
•
Each of the businesses believed that it is important to plan for emergencies. One
business indicated that it was present for the 1955 or 1964 floods. When asked
whether they were prepared for a flood or other disaster, two businesses answered
in the affirmative, but one identified transportation as being limited. One
responded “somewhat,” indicating a level of uncertainty. Two of the businesses
indicated that they had emergency plans and that their employees are aware of the
plan. One business did not have an emergency plan and did not have any
employees.
•
All of the businesses expressed an interest in meeting to discuss disaster planning,
but also indicated the schedule of the meeting would affect the ability to attend.
28
•
One business commented that a main concern should be alternative evacuation
and transportation routes out of the Hoopa Valley, especially in light of the
current conditions of our highways and roads.
The following businesses were contacted initially by telephone call and later received the
survey: Tent-man Sales, Burger Barn, Coast Central Credit Union, Laura’s Kitchen,
Thunderbird Intertribal, and Office FX.
Meeting with Community Elders
In August 2011 OES staff performed community outreach and education at the Hoopa
Valley Tribe’s 23rd Annual Sovereign’s Day Event using a Hoopa Community
Emergency Preparedness Survey targeting tribal elders and families. Distribution of
Household Disaster Preparedness Surveys, and the following handouts; Six Ways to Plan
Ahead for an Earthquake Event During Earthquake – Remember To STOP – COVER &
HOLD ON, What to Do During an Earthquake, and Disaster Preparedness For Seniors by
Seniors (American Red Cross/HSMI), Preparing Makes Sense for Older Americans –
Brochure targeting tribal elders made the event a success. Outreach and emergency
preparedness education was shared with tribal elders at the Senior Nutrition Center and at
various other community meetings from August – October 2011.
A meeting with Tribal Elders took place on May 26th, 2006 at the Senior Nutrition
Center in order to ascertain as much historical information as possible from these
valuable resources. Other informal interviews occurred between April and June usually in
passing, as sometimes the best place to visit an elder would be in a public place such as
the post office or grocery store. Interviews took place as well as questionnaires in order to
maintain anonymity for some of our elders do not wish to be recorded. Questions were
geared toward all disasters of memory however, there were only a few that most chose to
talk about.
The 1955 and 1964 floods were the most memorable for the interviewees who ranged in
age from 65 to 90 years old. The 1999 Megram fire was another disaster that many could
remember due to its recent occurrence as well as its devastating impact to the elderly in
particular. Other disasters of memory included other smaller floods, numerous power
outages, and food and drinking water shortages.
29
Many elders spoke of how they were taught to prepare for such emergencies by always
having extra blankets, candles, kerosene, water, and canned foods. Several individuals
spoke of how they would spend all summer canning fish and fresh fruits and vegetables,
so they would never be without during a harsh winter. Most said that if they ever ran out
of food that they could always borrow or trade for another who had surplus, but
community members learned to rely on each other in times of need.
We asked about evacuations and the only time they could really remember was in the
1999 Megram Fire where many were forced to leave their homes due to elevated smoke
levels that were very harmful to elders in particular.
In the 1955 and 1964 floods, nobody really left as they just had to wait it out until
supplies were dropped by helicopter. By the time the flood came through all the roads
were blocked off anyway, so there was no option of evacuation. Many who were washed
out of their homes were forced to stay at the school or with other family members or
relatives. The military dropped supplies such as sleeping bags, K Rations, flour, sugar,
powdered milk and other necessities. From speaking to many elders about these disasters,
there was a unifying theme which was that our community really knows how to come
together and help each other in times of need.
There were numerous stories of slides and power outages from severe storm events,
however they had a difficult time remembering exact years and dates for such disasters.
Not many remembered any great earthquakes in their lifetimes, but many have felt small
tremors here and there. There was a wealth of oral tradition in speaking with the elders.
Some told stories of great tsunami’s thousands of years ago that actually altered the flow
of the Trinity River, and of giant earthquakes that formed certain peaks and rock
formations in the Hoopa Valley.
30
Program Integration - §201.4 4(b)
Integration with Ongoing Tribal Planning Efforts
The Hoopa Tribal Council approves all projects and plans that the Tribe undertakes. The
volume of projects and plans create a wide range of timetables. In order to consolidate
information, dates, and public comments, tribal ordinance (the Legislative Procedures
Act) requires particular methods for distributing information to tribal departments and the
public. In addition, it specifies rules for public hearings and receiving public comments
prior to final enactment of legislation or major policy of the Tribe. In this regard,
planning efforts affecting the Hoopa Valley receive the widest possible distribution and
public input. Any final update draft of the MHMP will go through this process, as all
other major tribal policies do, to ensure that any interested party that has not already
commented has the opportunity to do so. Also, the MHMP will be the guiding document
for any new development, existing development or disaster response/recovery projects.
The mitigation planning is intended to complement existing tribal policies affecting the
public, including the Emergency Operations Plan (EOP) under the federal NIMS
requirements, Forest Management Plan (FMP), Tribal Transportation Plan (2002-2007),
EPA Spill Prevention Plan, and a preliminary Land Use Plan. Besides these
comprehensive, multi-department policies listed, the Tribe has long established and
enforced ordinances aimed to protect people and property. The formation of a tribal
court, development of civil action laws and rules of court was part of Hoopa’s pioneering
efforts in California. From 1986 to the present, the Tribe has adopted more than 50 fully
sectioned out ordinances aimed at regulation of resources and conduct on the reservation.
Some, like the Land Assignment Ordinance to regulate responsible land use and safe
development out of harm’s way, the Conservation and Trespass Ordinance to protect
tribal forest resources, the Netting and Fishing Ordinance to protect fishing resources,
and the Riparian Protection Ordinance to protect gravel and surface mining resources,
have been in effect for more than 10 years and survived complex challenges in federal
and state courts. Others, like the Solid Waste Ordinance regulating solid waste disposal
4
In October 2008, 201.4 was replaced with 201.8 Tribal Mitigation Plan.
31
and the Traffic Code regulating driver conduct and fines on the reservation, have gone
through a more recent adoption and enforcement.
Integration with FEMA Mitigation Programs and Initiatives
The MHMP was developed utilizing FEMA 386 documentation to develop the 2006 plan
and for the 2011 update. A review of FEMA Mitigation Best Practices was the guideline
for acceptable mitigation practices. Using this review of FEMA approved mitigation
projects created a template for searching for solutions to hazards likely to occur on the
reservation.
The underlying goal is to become NIMS compliant by FY07. The Tribe met this goal in
2007, and most recently in again April 2009 as part of the annual NIMS compliance
review.
The Emergency Manager will take full responsibility to update the Tribal Council on
developments regarding mitigation. Currently, in the State of California, there are no
“open” disasters to fund Hazard Mitigation Grant Program (HMGP). However, with the
return of Pre-Disaster Mitigation (PDM), Hoopa Emergency Manager will maintain the
connection with FEMA Region IX to potentially obtain funding for projects or a plan
upgrade. Under Flood Management Assistance, the Hoopa Emergency Manager will
develop outreach to the current Council and Administration in order to keep them aware
of funding streams for flood mitigation. The Emergency Manager is aware of the
differences between mitigation and NIMS compliance. Since the review of the mitigation
plan, the planner has been reassigned and replaced with a trained mitigation planner.
In being NIMS compliant, the Hoopa Tribe can;
•
Ensure common and proven incident management doctrine, practices, and
principles are used to plan for, protect against, respond to, and recover from
emergency incidents and pre-planned events;
•
Maintain a response operation capable of expanding to meet an escalating
situation and the ability to integrate resources and equipment from intrastate and
interstate mutual aid agreements, state-provided assistance, and federal
government response;
32
•
Order and track response assets using common resource typing and definitions,
and draw on mutual aid agreements for additional assistance;
•
Establish staging and allocation plans for the re-distribution of equipment,
supplies, and aid coming into the area from other localities, states, or the federal
government through mutual aid agreements;
•
Conduct situational assessments and establish the appropriate ICS organizational
structure to effectively manage the incident; and
•
Continue to maintain communication processes, procedures and protocols that
will ensure effective interoperable communications among emergency responders,
9-1-1 centers, and multiagency coordination systems (Emergency Operations
Centers).
Purpose and Need for the MHMP
Tribal and local authorities, not federal, have the primary responsibility for preventing,
responding to, and recovering from emergencies and disasters. The overwhelming
majority of emergency incidents are handled on a daily basis by a single jurisdiction at
the local level. Implementation of the NIMS in every tribal and local jurisdiction
establishes a baseline capability that once established nationwide, can be used as a
foundation upon which more advanced homeland security capabilities can be built. The
Office of Emergency Services values the information within the MHMP and regard it as
the foundation document for Emergency Management. Homeland Security Presidential
Directive 5 (HSPD- 5), Management of Domestic Incidents, requires all federal
departments and agencies to adopt and implement the NIMS, and requires state 1 and
local 2 jurisdictions to implement the NIMS to receive federal preparedness funding.
The Hoopa Tribe’s Office of Emergency Services (OES) is the focal point of all
emergency or disaster preparedness and management as well as public information
center. This department is responsible for maintaining and updating the MHMP, EOP,
Hazardous Materials Plan and any other personal health and safety document under the
Tribes archives. Our priority goal is to save lives, reduce risk & lessen property damage.
33
Furthermore, Hoopa OES maintains compliance with federal regulations including NIMS
compliance and maintaining a FEMA approved MHMP.
Through a systematic process, this MHMP analyzes the possible impacts of hazards on
vulnerable areas of the community infrastructure and focuses on the continued wellbeing of the Hoopa Valley Tribe. Preliminary conceptual hazard plans and models are
utilized for the basis of hazards analysis. Conceptual plans have been analyzed to
represent the maximum level of damage based in hazard type. The Disaster Mitigation
Act of 2000 requires that Tribes along with local governments have a disaster mitigation
plan that explains how you identify hazards, risks and vulnerabilities as well as how to
prioritize mitigation actions to deal with these hazards. The goal is to learn how to solicit
technical support when needed as well as develop a federally approved mitigation plan to
be eligible for future pre and post disaster funds through FEMA.
According to the 2010 Census there are 3,041 people living on the Hoopa Valley Indian
Reservation in 960 occupied homes. The Hoopa Tribe is a Self-Governance Tribe and
maintains a government-to-government compact; however the Tribe remains reliant on
Timber as its economic base. The Tribe has millions of dollars in assets and structures, as
we will address later in this plan. Natural disasters can occur frequently with the amount
of Tribal Assets and natural resources at risk. Protecting our community and member
wellbeing is very important, however protecting our way of life and cultural traditions is
of utmost importance.

Chapter 2 – Description of the Hoopa Valley Tribe Community and
Reservation
Introduction
The purpose of this section of the Hoopa Valley Tribe’s MHMP is to describe the
existing environment, land use patterns, and resources of the Hoopa Tribe and
Community. This chapter of the MHMP contains nine sections each of which may
include pertinent sub-subsections. The land uses, topography, climate, hydrology, soils,
watersheds, and surface water resources on the reservation affect the vulnerability of the
Reservation to natural hazards. This section briefly describes each of these elements.
Land Resources
Topography
The Hoopa Valley Indian Reservation, California’s largest Indian Reservation, is located
in the northeastern portion of Humboldt County (See Location Map Below). The
Reservation is shaped geometrically similar to a square with sides approximately 12
miles in length. The valley itself lies near the center of the Reservation. Hoopa Valley is
located about 65 miles east of Eureka and 120 miles west of Redding. It is 12 miles north
of Willow Creek and 10 miles south of Weitchpec, where the Trinity River flows into the
Klamath River. The valley floor, an alluvial plain approximately 6 miles long by 1 mile
wide and considered the Urban Zone in Chapter 3, is bisected in a north-south direction
by the meandering Trinity River. The Hoopa Reservation is separated into 8 districts, or
fields, which represent traditional villages of the Hoopa People. The field names are
Norton, Soctish/Chenone, Mescat, Hostler, Agency, Bald Hills, Matilton and Campbell.
Except for the relatively flat Hoopa Valley, most of the Reservation is steep and heavily
forested.
The Bald Hills area is on the northwest side of Reservation and considered Upland
Residential according to the hazard assessment areas in Chapter 3. The east side of the
35
region slopes steeply into the Trinity River which defines the area’s eastern border. The
western side of the area is defined by the change in slope to Hoopa Mountain and French
Camp Ridge. The rest of this mostly forested area of the Reservation is considered
Upland Regions as listed later in Chapter 3.

Soil Types & Characteristics
Past geologic conditions, the steep terrain and high amount of precipitation have all
contributed significantly to soils formation in the Hoopa Valley. These factors have
combined to produce erosion, which resulted in thicker soil mantle along the Trinity
River and thinner soil layers on the mountain valley slopes. The valley contains a series
of terraces; each composed generally of differing relationship of soils. The Agency and
Chenone soils lie at the lower terraces along the Trinity River. These are the most
recently formed and are coarse textured. They also lack profile development and have a
high base saturation. On the next terrace level are the Soctish soils, which are older than
the Agency and Chenone soils. They are finer textured, have a very weak profile
development, and a medium base saturation. Above the Soctish soils are the Norton soils,
which are the oldest. These soils are finer in texture, have a weak profile development
and have low base saturation. Matilton soils are also found at the higher terraces and, like
the Norton soils, support heavy forest vegetation. Above the higher terraces are the steep
upland areas of the valley, which support forest vegetation.
Soil types have been extensively mapped for the Hoopa Valley Indian Reservation. A soil
survey conducted in 1975 by Agricultural Extension Service and the University of
California at Davis classifies agricultural soils on the valley floor as follows:
Table 4 – Soil Grades and Acreage (based on 1975 UC Davis Soil Survey)
Grade 1 soils are suitable for a wide range of crops with excellent yields. Grade 2 soils
are suitable for a myriad of crops with average yields. Grade 3 soils have a limited range
of crop suitability but specialized crops may give good results. Grade 4 soils are either
38
marginal in production, or have been developed for human use. Soil surveys conducted
on the Hoopa Valley Indian Reservation are classified as Order III, or reconnaissance
level surveys. Soil characteristics, qualities, and ratings of interest to land managers on
the Hoopa Valley Indian Reservation were presented in a report entitled Soils of the
Hoopa Valley Indian Reservation, Humboldt County, California, Annette Parsons, 1985.
There are four main hydrologic soil groups, which indicate the soil’s potential for runoff.
Factors considered in determining the hydrologic soil group include structure and texture
of surface horizon, permeability of surface horizon, and the depth at which a reduction in
permeability begins. The groups are classified as follows:
Group A - very low runoff potential
Group B - low runoff potential
Group C - moderate runoff potential
Group D - high runoff potential
Geologic & Mineral Resources
The Hoopa Indian Reservation is in the Klamath Mountains geologic province. A
northerly trending, generally steep, thrust fault, the South Fork Mountain fault, separates
the Klamath Mountain from the Coast Range (Irwin, 1966). On the upper, or eastern,
plate are mildly metamorphosed shale, phyllite, thin-bedded chert, and altered volcanic
rocks assigned to the Galice Formation of the western Jurassic belt. Together with other
metamorphosed clastic sediments, chert, and volcanic rocks of the western plate are
metagraywacke, chert, and volcanic rocks of the Franciscan Formation that are more fully
described in the section on geology of the Coast Ranges. Just below the thrust these
underlying rocks are somewhat more metamorphosed than elsewhere and are referred to
as the South Fork Mountain schist (Irwin, 1966). Along the sole of the thrust is a sheet of
serpentinized peridotite of variable thickness that comprises a nearly continuous belt
extending northward into Oregon. Other thinner bands of serpentine, with northerly trend
found farther east, are believed to have been injected along steep faults. The east edge of
the Hoopa Valley Reservation cuts across a bulge on the western side of the extensive
39
granitic Ironside Mountain batholith. The rock here is chiefly quartz diorite or diorite and
has been radiometrically dated to the Jurassic period at 165-167 million years old.
Along Beaver Creek, about 4 miles north of Hoopa, are small patches of sandstone, shale,
conglomerate, and lignite that are poorly understood. They may be Oligocene equivalents
of the Weaverville Formation that contains coal near Hyampom and Hayfork, or they
may be a landward extension of the Miocene Wimer Formation of Maxson.
The sand and gravel deposits of the Hoopa Reservation have been mined for use nearby
in road or building construction by Hoopa Aggregates, a Tribal enterprise. The available
quantity is enormous, and no doubt this material will continue to be used wherever there
is sufficient local demand.
Seismic Conditions
The Hoopa Valley is not located within an Alquist-Priolo special study zone as classified
by the California Division of Mines and Geology (CDMG) thus indicating that no active
faults (movement occurring in the last 10,000 years) or potentially active faults
(movement occurring in the last 2.0 million years) are identified or significantly close to
the Reservation. Furthermore, review of the Preliminary Fault Activity Map of
California, CDMG Report 92-03, 1992 indicates that no known active faults are mapped
either in the reservation boundaries or on nearby land. There is however, an inactive fault
known as the Beaver Creek Fault located near Beaver Creek at the base of Pine Creek
Road.
40
Water Resources
Hydrology
The Reservation is bisected in a north-south direction by the Trinity River. The Klamath
River flows in an east-west direction through a small portion of the far-northeastern part
of the Reservation referred to as Saints Rest Bar. A number of smaller streams flow into
the Trinity and Klamath Rivers within the Reservation. The largest of these streams
include: Mill Creek, Hostler Creek, Tish-Tang Creek, Campbell Creek, Supply Creek,
and Soctish Creek. The valley floor consists of a sequence of prominent stream terrace
benches that step upward in elevation and age from the active channel of the Trinity
River. The terraces or benches represent ancient to modern flood plain levels. Across the
valley floor, the Trinity River has formed a series of broad meanders. The broad
meanders of the Trinity River naturally divide the alluvial valley into paired sets of
terraces, which the Tribe defines as “fields” of the Reservation.
Lewiston Dam and Trinity River Division
Prior to the completion of the Trinity and Lewiston Dams in 1963, flows in the Trinity
River were substantial year-round. Flows of the minor tributaries to the Trinity River
within the Hoopa Reservation are directly related to seasonal distribution of precipitation
in the area, and over 80 percent of the flows of these streams occur during the months of
November through March. Low summer flows in these tributaries have often been
inadequate to meet demands of water users for whom the tributary constitutes a sole
water source. The Hoopa Valley East and West water systems were interconnected by the
Trinity River Bridge connection and the pipeline through Blue Slide to form the Hoopa
Valley-Wide system. With these connections, the ability to move water between the east
and west of the Trinity River alleviated some of the water shortages. The Telescope
springs water system was incorporated into the Valley-Wide system when the Campbell
Creek water treatment plant was constructed.
When Congress authorized construction of the Trinity River Division (TRD) of the
Central Valley Project (CVP) in 1955, the expectation was that surplus water could be
41
exported to the Central Valley without harm to the fish and wildlife resources of the
Trinity River. The TRD began operations in 1963, diverting up to 90 percent of the
Trinity River’s average annual yield at Lewiston, California. Access to 109 river miles of
fish habitat and replenishment of coarse sediment from upstream river segments was
permanently eliminated by Lewiston and Trinity Dams. Within a decade of completing
the TRD, the adverse biological and geomorphic responses to TRD operations were
obvious. Riverine habitats below Lewiston Dam degraded and salmon and steelhead
populations noticeably declined.
In 1981, the Secretary of the Interior directed that a Trinity River Flow Evaluation
(TRFE) study be conducted to determine how to restore the fishery resources of the
Trinity River. The TRFE study provides recommendations to the Secretary to fulfill fish
and wildlife protection mandates of the 1955 Act of Congress that authorized the
construction of the Trinity River Division of the Central Valley Project. In June of 2000,
the TRFE was issued and the Secretary of Interior signed the Record of Decision (ROD)
in the fall of 2000 authorizing the release of additional water into the Trinity River,
equivalent to 48 percent of the river’s original natural flows.
Groundwater
The groundwater basin of the Hoopa Indian Reservation is confined to the terraces
adjacent to the river in the valley itself. The storage capacity of the Hoopa Valley has
been estimated by the Department of Water Resources, State of California, at
approximately 19,000 acre feet, has a maximum well yield of 300 gallons per minute, and
does provide a usable source of “small plot” agricultural water.
Hoopa Valley, in Humboldt County, is a 5 square-mile basin drained by the Trinity
River. Trinity River flow data has been collected by the USGS since the 1960’s. The
Hoopa Tribal Environmental Protection Agency has been collecting data on the Trinity
River and priority streams on the Reservation since 1989. Data from the lowest recorded
flows indicate that creek flows recorded in October can be less than half than the flows
42
recorded in June. Creek flow data from 1995 to present are recorded utilizing real-time
continuous data recorders.
The Hoopa Valley groundwater area is approximately 7 miles in length and 0.7 miles
wide with narrow, gorge-like canyons at both ends of the valley. Surface waters from the
Trinity River and springs along the edge of the valley provide the principal source of
water supply to the valley.
The terraces bordering the river on each side slope gently upward from the river to merge
with alluvial sands near the edge of the valley. The alluvial deposits are generally less
than 65 feet in depth along the center of the valley and consist mostly of terrace deposits
bordering each side of the river. (Winzler & Kelly, 1974)
The groundwater within the valley area occurs principally in unconsolidated alluvial
deposits. The water table appears highest at the edge of the valley near the tributary
streams and slopes away from them toward the Trinity River. Examples of this are the
wells supplying the Agency system adjacent to Supply Creek and to a lesser extent wells
that were constructed along Mill Creek which are of high yield but of low water quality.
The rate of groundwater movement, because alluvial deposits are highly permeable, is
quite rapid. The groundwater moves in relatively thin sheets above the underlying
bedrock, creating a very thin zone of saturation, resulting in notoriously low yields with
high draw-downs during late summer months.
One “valley-wide” community water system currently serves the Hoopa Valley east and
west of the Trinity River. According to the Hoopa Valley Public Utilities District, there
were a total of 539 metered service connections, with about 280 connections on the east,
and 259 on the west in 2004. Approximately 2,100 people are served by the water
system. The water system has various surface and groundwater sources, with varying
manners of treatment.
43
The recharge of groundwater in the Hoopa Valley is dependent upon two factors: direct
infiltration of precipitation, which falls on the terrace deposits, and the infiltration of
runoff derived from the various perennial streams. Groundwater can be recharged very
rapidly because of the high permeability of the material that composes the alluvial
terraces. The high permeability of the alluvial terrace deposits also allows for the rapid
movement of groundwater to points of discharge; therefore groundwater is retained on
the alluvial terraces for only short periods of time.
Upland areas are characterized by thin layers of surface soils exiting over bedrock. Soil
depths in upland areas vary with topography but are generally less than sixty inches. The
relatively shallow depth to lithic contact in upland areas means that groundwater is
sporadically present in limited quantities. The low amount of available groundwater in
upland areas makes the use of wells as a source of domestic water problematic or
impossible. Like most of California, Hoopa Valley enjoys a Mediterranean type climate
with hot dry summers and cool moist winters. The mean annual temperature is 57°F.
Recorded extremes include a low of 7°F and high of 118°F. The mean annual
precipitation is 57 inches with 90 percent occurring between October and April. Snowfall
on the valley floor is rare, but elevations above 4,000 feet, in the adjoining mountainous
areas, receive substantial amounts.
Droughts and Floods
During the winter of 1992-93, the area experienced an end of California’s seven-year
drought. Precipitation for the period ending December 30, 1992 exceeded 47 inches. The
Hoopa Valley Indian Reservation and surrounding areas sometimes receive warm rains
during the winter months, which quickly melt existing snow-packs. When this happens,
rivers and streams overflow their banks and flooding occurs. Major floods occurred in
1955 and 1964. The flood of 1955 was declared the 100-year flood (has a one percent
chance of occurrence in any given year) and the 1964 flood was declared a 1000-year
flood. These flood zone areas have been mapped by the U.S. Bureau of Reclamation and
entered into the Tribe’s GIS database.
44
Local regulations controlling activities within flood plains are contained in the
reservation’s draft comprehensive plan, land-use volume. The flood plain zone is
intended to be applied in areas subject to inundation by the 100-year flood and areas
subject to high liquefaction potentials as delineated in the Tribe’s 100-year flood plain
map and/or the U.S. Bureau of Reclamation’s 100-year flood plain for the Trinity River.
Land use is regulated within these areas to protect lives and property from destruction
and damage due to liquefaction, floodwaters and the transportation by water of wreckage
and debris, to protect the community from the cost that may be incurred when unsuitable
or premature development occurs in such areas, and to allow uses which are appropriate
in such areas. Mapping of these types of floods and maximum inundations can be found
in the Appendices.
Wetlands
In 1999 the Tribal EPA and Humboldt State University cooperated on a wetland
identification project using a geographic information system (GIS) and infrared aerial
photo interpretation. Data layers from the GIS were queried for attributes indicative of
wetland occurrences (soil, vegetation, slope and hydrography). Air photo interpretation
was then used to further validate the GIS results. The study area included Mill, Supply
and Tish Tang watersheds (uplands) and the Valley floor. Fifty potential wetlands were
identified: 13 on the Valley floor & 37 in the uplands. Six Valley floor wetlands and 3
upland wetlands were field verified. Aerial extent of these wetlands was not determined
due to the site-specific nature of wetland boundaries. Delineation of wetlands will
normally be conducted when a proposed project is adjacent to it.
Due to the restriction of agricultural, residential and commercial development largely to
the valley floor, long-term loss of wetlands in upland areas has probably been minimal.
Some upland riparian wetlands undoubtedly have been lost to road construction or stream
course alterations. Past logging practices have contributed to down-cutting of drainages
and sediment deposition in some areas, altering or destroying riparian vegetation.
Changes in species composition have undoubtedly occurred due to logging near to or
45
within the riparian corridors. No attempt was made to quantify change in wetland quality
or loss of wetlands as a result of these factors.
In contrast, decline in amount or quality of wetlands on the valley floor has probably
been significant over the past 50-60 years. Black cottonwood/alder swamp and other
stagnant wetlands were probably historically widespread in the valley, associated with the
mouths of some drainages. BIA agents apparently encouraged modern techniques of
farming about the turn of the century. Flat, moist, and fertile land would have been
desirable, since most crops required irrigation. Additional wetlands were probably lost to
mill construction and related water diversions later in the first half of the century.
Finally, significant loss or decline in quality of wetlands in the valley may have occurred
as a result of the 1964 flood and subsequent stream re-channelization by the Army Corps
of Engineers. Those impacts may have contributed to the high occurrence of exotic
species in the valley. Subsequent construction of irrigation channels serving Campbell
Field and other areas of the valley probably caused additional losses. Inspection of 1962
aerial photographs indicated no significant change in non-riparian wetlands in the valley
from 1990 photos. Therefore, aside from flood-related impacts on riparian vegetation
after 1964, the major historical impacts to wetlands on the valley floor appear to have
occurred prior to 1962.
46
Air Quality
General Air Quality Concerns
The overall air quality of the Hoopa Valley Indian Reservation and general vicinity is
excellent since topography and wind conditions usually limit the infiltration of outside
pollutants. When the right climatic conditions occur (a low inversion layer and a gentle
north or northeasterly wind); air pollution may be noticeable and possibly objectionable.
However wildland fires can cause serious impacts to air quality in Hoopa as documented
during the 1999 Megram fire where the first ever state of emergency was declared due to
poor air quality.
The major influence upon air quality in the area is from slash burning, cars and logging
trucks, with most of the vehicle generated pollutants occurring on the unpaved roads on
the Reservation. Major logging haul roads generate dust pollutants during the summer
months. Residential generators also have a minor influence, with most of the pollutants
created by fireplaces, woodstoves, and residential burning. With the proper atmospheric
conditions and sufficient densities, smoke may be noticeable and even objectionable at
certain times. However, even under these conditions, the Hoopa Valley Indian
Reservation remains “in attainment” of standards under the Clean Air Act.
Air Quality Monitoring
2008 Public Health Threat/Air Quality Alert Results in Historical Presidential
Declaration
The 2008 Fire Siege of Northern California caused from lightening strike fires turning
into a Public Health Threat/Air Quality Alert for the residents living on the Hoopa Valley
Indian Reservation and in Northern California. The Hoopa Tribe evoked their Emergency
Operation Plan (EOP) and Incident Command Center and dealt with the response,
mitigation, and recovery efforts of the 2008 Public Health Threat. Collaborative efforts
were coordinated with Humboldt County OES and CA State OES, USFS, FEMA,
Humboldt County Public Health, NCIDC, Red Cross, NWTEMA, IHS, UIHS, CDC,
County Law Enforcement, Calif. Hwy Patrol, CAL FIRE, and Air Quality Management
47
District. The Public Information and Communications Plan were put in place with PSA’s
and community meetings. As a result of the proactive efforts during the 2008 Public
Health Threat/Air Quality Alerts the Hoopa and Yurok Tribes were added to a
Presidential Declaration for this historical 2008 Public Health Threat/Air Quality Alert.
Air Quality Response
Effective March 16, 1998 the Clean Air Act (CAA) was amended to include section
301(d) Tribal Authority Rule TAR. In the TAR, the EPA set forth its interpretation that
the CAA is a delegation of Federal authority, to Tribes, approved by EPA to administer
CAA programs in the same manner as States over all air resources within the exterior
boundaries of the Reservation for such programs. However, unlike States, Tribes have
the flexibility to choose which parts of the CAA they wish to implement based on the
specific needs of the Tribe.
The Tribal Environmental Protection Agency (TEPA) monitors air quality continuously
throughout the year. TEPA utilizes mini-volume portable PM10 on-site samplers and a
Tapered Element Oscillating Microbalance (TEOM) to monitor air quality on the
Reservation. When smoke from wildfires invades the valley and degrades air quality,
TEPA responds by tracking increases in particulate matter (PM10) in real time. Increases
in PM10 values are compared to numeric criteria representing the level of threat to public
health. These criteria are organized into an Air Quality Action Plan (AQAP). The AQAP
serves as an inference of public health threats relative to air quality conditions. It
identifies objective criteria on stage levels relative to public health threats and provides
recommendations for community actions to protect respiratory health and mitigate the
impacts from increasing smoke.
The Tribal Environmental Protection Agency (TEPA) monitors air quality when
inversion layer conditions exist, or when forest fires may create objectionable air quality
conditions. TEPA utilizes mini-volume portable PM10 on-site samplers and a Tapered
Element Oscillating Microbalance (TEOM) to monitor air quality on the Hoopa Valley
Indian Reservation.
48
The 1990 amendments to federal Clean Air Act Section 176 required the EPA to
promulgate rules to ensure that federal actions conform to the appropriate State
Implementation Plan (SIP). These rules, known together as the General Conformity Rule
(40 CFR §§ 51.850-.860 and 40 CFR §§ 93.150-160), require any federal agency
responsible for an action in a non-attainment or maintenance area to determine that the
action is either exempt from the General Conformity Rule’s requirements or positively
determine that the action conforms to the applicable SIP. In addition to the roughly 30
presumptive exemptions established and available in the General Conformity Rule, an
agency may establish that forecast emission rates would be less than the specified
emission rate thresholds, known as de minimis limits. An action is exempt from a
conformity determination if an applicability analysis shows that the total direct and
indirect emissions from the project would be less than the applicable de minimis
thresholds and would not be regionally significant, which are defined as representing 10
percent or more of an area’s emissions inventory or budget.
49
Health Effects From Smoke
Wood smoke is a major air pollutant composed of a combination of fine carbon particles
and gases. Carbon monoxide (CO) is an odorless gas produced from burning wood
without enough air. CO reduces the ability of a person’s blood to supply oxygen to body
tissues. Even small amounts in the air can stress your heart and reduce your ability to
exercise. Nitrogen Dioxide (NO2) is also emitted as a gas. It impairs proper function of
the respiratory system and reduces its’ ability to fight infection. Volatile Organic
Compounds (VOC’s), are evaporated carbon compounds which react with (NO2) in
sunlight to produce ozone smog. When exposed to water vapor this combination
produces acid rain. In a combustion process, VOCs change into irritating and cancer
causing substances such as benzene, formaldehyde and polycyclic aromatic
hydrocarbons, which are very harmful to human health. Wood smoke also contains
Particulate Matter, (PM10), microscopic solid and liquid particles 10 microns or less.
Most wood smoke particles average less than one micron and can travel deep into the
lungs causing irritation and leading to chronic lung disease and cancer.
Wildland Fires
In 1991, the Hoopa Tribe through the self-governance process compacted the Wildland
Fire program from the BIA forming the Hoopa Fire Department. Since 1991 there are
nearly 300 fires on an average started each season to which that Wildland Fire responds.
Under Mutual Aid agreements the Fire Department is able to work with other agencies to
meet their objectives. The Hoopa Valley Volunteer Fire Department is one of these
mutual aid agencies that provide structural fire protection and suppression during a
Wildland fire event on the Hoopa Valley Indian Reservation.
Since coniferous forests surround the Hoopa Valley, the potential for outbreaks of
wildland fires is very high, especially during dry times of the year, where large fires have
been known to become unmanageable. The Hoopa Fire Department provides initial and
extended attack of fire suppression for Wildland fires on the Hoopa Reservation, however
there have been instances of large fires being very destructive and costly not only to the
50
Tribe but surrounding State and Federal agencies as well. Table 5 shows the number of
fires documented by Hoopa Fire Department over the past 11 years with the total acreage
burned on Reservation and the estimated costs to the Tribe.

The 1999 Megram Fire
The Hoopa Valley air program is operated with the underlying premise that local
catastrophic wildfires could erupt in any given year. Local wildfires produce extreme
plumes of smoke that settle in the valley, often causing hazardous air quality conditions
and threatening the immediate health of people. Particulate matter PM10 has been
measured as high as 325-800 μg/M3 for several days to a week during major fires.
Therefore, preparedness is of primary concern in the Hoopa air quality program.
The winter of 1998/1999 affects of the La Nina ocean currents altered weather patterns in
Northern California, causing a particularly dry winter and spring. This led to an
extremely dry summer and an increased susceptibility to wildfires. A total of 93,702
wildfires covering 5,661,976 acres burned Nationwide in 1999 resulting mostly from
lightning strikes. In August 1999 heavy fuels, extreme high winds and dozens of
51
lightening strikes set off the Big Bar/Megram fire complex East of Hoopa. This fire
engulfed 140,947 acres and burned from August 23rd to November 3rd 1999. Intensified
by autumn season inversions, smoke from this fire filled local valleys like Hoopa and
increased air-born particulate matter (PM10) from a normal average of 22 μg/M3 to over
800 μg/M3 for up to 24 hours or more. This situation cannot be tolerated by the
community. Therefore, in response to this event, an air quality action plan was developed
to act as an objective guide for alerting the local Hoopa community of air quality
conditions
and
the
associated
52
response
for
action.

Living Resources
It is a policy of the Hoopa Valley Tribal Council through the Hoopa Forest Management
Plan (FMP) to actively protect and conserve non-market resources associated with the
commercial forestlands on the Reservation. The management plan goes beyond state and
federal listings of rare and endangered species by identifying and providing for culturally
significant plant and animal life.
Since the Tribe actively manages the forest resources of the Reservation, the Hoopa
Tribal Forestry Department has initiated a comprehensive wildlife management program.
This program includes over twelve years of biological surveys, a Spotted Owl Habitat
survey and wildlife assessments, which are performed prior to all projects. As a result,
wildlife data on the Reservation is comprehensive as well as creditable.
Threatened Wildlife Species
The Hoopa Tribe took over management of its forest resources in 1989 when it became
one of the first Self Governance Tribes in the nation. Following the federal listing of the
northern spotted owl as a threatened species in 1990, Tribal Forestry hired a wildlife
biologist in the spring of 1991. From that point forward the tribe has been developing a
wildlife program focused primarily on surveying and monitoring of federally threatened
or endangered (T&E) species but also attempting to develop comprehensive management
of the wildlife resource.
Currently there are 2 species of wildlife that are federally listed as threatened (marbled
murrelet and northern spotted owl) and 2 candidate species (fisher and yellow-billed
cuckoo). Yellow-billed cuckoos have not been confirmed on the reservation and it is
doubtful that they are present. Extensive surveys of the potential marbled murrelet
nesting habitat have been conducted from 1992-2006 but have not confirmed occupancy
of any reservation habitat. The U.S. Fish and Wildlife Service (FWS or Service) has
removed survey requirements within the eastern portion of the reservation falling within
marbled murrelet zone 2.
Tribal Forestry is currently working on a Programmatic
54
Biological Assessment for the recently completed 15 year Forest Management Plan
(FMP) (2011-2026) which will be submitted for Consultation with the FWS in the next
several months. Survey requirements for marbled murrelets are expected to be dropped
as a result of the tribe’s intensive survey efforts and the establishment of a small reserve
of forest stands in the only area where potential marbled murrelet detections were
recorded using radar surveys in 2005 and 2006. Loss of potential marbled murrelet
habitat will occur through implementation of the tribe’s FMP and those losses will be
reported to the Service annually.
The tribe has also conducted intensive surveys and demographic monitoring of the
northern spotted owl population within the reservation since 1991. With 20 years of
demographic data the tribe has been able to document the decline of the population.
However, the cause of that decline is uncertain. The objectives of the monitoring were to
determine the effects of the tribe’s FMP on the species.
For the first 15 years of
monitoring the reservation population was essentially stable. However, the population
began to decline rapidly during the last 5 years. Although the cause of the decline can
not be positively identified, tribal biologist suspect that it is the result of a rapidly
increasing barred owl population rather than the implementation of the tribe’s FMP.
Tribal forestry has also monitored and reported changes in spotted owl habitat along with
the demographic data to the Service and will continue to do so following completion of
the programmatic consultation of the revised FMP.
In addition, Tribal Forestry
implements seasonal restrictions on disturbance activities near active spotted owl nesting
pairs and provides environmental review of other tribal department projects.
The fisher is a medium sized forest carnivore that has been of concern to biologists for
several decades within their Pacific coast range.
The species also holds cultural
significance to the tribe as its hides are used for dance regalia. Fishers are closely
associated with dense forest cover throughout their range in California. Fisher

populations in Washington, Oregon and California were substantially reduced following
the arrival of European settlers. They were believed to be completely extirpated from
Washington, and over 90% of their historic range in Oregon. In addition, they are
missing from at least 50% of their historic range in California.
Fortunately the
population in northern California has persisted and been considered relatively healthy for
many decades and the highest densities of fishers in the west is centered on the Hoopa,
Willow Creek, Orleans and surrounding area.
56
Tribal Forestry has been conducting
research on fishers since 1992 including two intensive radio telemetry studies (1996-1998
and 2005-present). Between 1998 and 2005 there was a fisher population crash on the
Reservation but due to funding restrictions no monitoring was occurring during that time
and the cause of the crash was unknown. Since 2005 the population has been relatively
stable or possibly growing slightly.
Both fishers and spotted owls are closely associated with structural elements of mature
and older forests for meeting a portion of their life requisites. Conservation of these
species requires close attention to habitat management and preservation. The biggest
threat to northern spotted owls at this time appears to be the invasion of the barred owl
followed closely by large scale habitat loss such as that which would be expected from
catastrophic fire. For fishers the biggest threats are large scale habitat loss or changes
which might occur as a result of climate change, including catastrophic fire. Fisher
research at Hoopa and more recently in the Southern Sierra’s has documented that fishers
are very vulnerable to predation by larger carnivores such as bobcats, mountain lions and
coyotes. These larger predators are associated with non-forested habitat, forest edges and
early seral forest stages. Causes of fisher mortality have been found to include a high
percentage of predation throughout California.
Therefore, changes in forest habitat
conditions through management, natural disasters (fires, insects, disease or blow down),
human caused disasters (fire spread of disease such as sudden oak death) or climate
change may create habitat conditions that favor the larger predators. In addition, it has
also become increasingly apparent that fishers are encountering rodenticide poisons in
their environment and are sometimes dying outright from the poisons but may also be
reduced in condition to the point where they are more vulnerable to other causes of
mortality including predation or natural diseases.
Following disasters impacts to T&E wildlife should be documented in a post disaster
Biological Assessment which is submitted to the FWS. Smaller scale impacts can be
reported in the tribe’s annual monitoring reports.
57
Tribal Traditional Species of Wildlife
Table I contains a list of species identified as having significance as cultural or
subsistence species important to the tribe (Traditional Species). These species have been
identified by speaking to tribal cultural leaders and inspecting historic regalia, clothing
and other items at the Tribal Museum. The table has indications as to potential effects of
the tribe’s FMP and a description of the type of affect and potential mitigating affects.
Effects of natural or human caused disasters would affect these species differently
depending on their habitat requirements. Species associated with the Trinity River,
Valley floor or the valley view shed could be heavily impacted by a dam break event but
not likely impacted much by wildfire. Many of the species are associated with edge, nonforest, shrub or early serial habitats and might be benefited by large scale stand
replacement fire.
A few (spotted owl, pileated woodpecker and fishers) could be
substantially impacted by catastrophic wildfire but not likely impacted by extreme
flooding.

Three threatened species under the Federal Endangered Species Act (ESA) are known to
occur on the Hoopa Valley Indian Reservation: the Northern Spotted Owl, the Bald
Eagle, and the Southern Oregon/Northern California Coasts Coho Salmon. The Marbled
Murrelet is another threatened species that may occur on the Hoopa Valley Indian
Reservation. Extensive surveys of potential Murrelet habitat on the reservation, occurring
between 1992 and 2002, have not discovered any Murrelets. The presence of Marbled
Murrelets on the Hoopa Valley Indian reservation is considered highly unlikely. Other
wildlife species on the Reservation that are afforded special protection under the
Migratory Bird Treaty Act include Peregrine Falcon, which was recently de-listed under
the ESA.
60
The Bald Eagle
The Bald Eagle is a rare but regular winter visitor to the lower Trinity River.
Occasionally individuals forage along the rivers and streams of the Reservation,
especially during salmon spawning seasons. At this time there are no known nests of
Bald Eagles on the Reservation. Management considerations for this species on the
Reservation include leaving snags and other perching sites along streams and rivers that
have salmon and steelhead runs (both present and potential).
The Northern Spotted Owl
The Northern Spotted Owl deserves special consideration because the subspecies that
occurs in the Pacific Northwest depends entirely on old-growth Douglas-fir forests. Its
population is considered to be declining because of the demise in its habitat due to timber
harvesting. Approximately forty-seven (47) Spotted Owl activity centers and 70 acres of
nesting habitat have been identified on forested lands in the Reservation. Spotted Owl
habitat constraints include large areas of old-growth Douglas-fir, the minimum size of
which has not been accurately identified. In a study conducted on Six Rivers National
Forest land adjacent to the Reservation by David Solis, (Masters Thesis, Humboldt State
University, June, 1983) Spotted Owls were found to concentrate most of their foraging
and roosting activities in stands of mature/old-growth timber greater than 250 acres in
size with an average stand size of over 500 acres. Nesting stands could apparently be
smaller. This should not be confused with minimum total area requirements however, as
these may be even larger. The geometric shape of stands managed for Spotted Owls can
be variable, but the following considerations may be useful:
1) Larger habitat areas are more useful than smaller areas.
2) Continuous habitats should be circular rather than linear.
3) Continuous habitats should be close and equally spaced from each other.
4) Fragmented habitats should be close and equally spaced from each other.
5) Corridors of suitable habitat should connect fragmented habitat areas.

The Coho Salmon
The
Southern
Oregon/Northern
California
Coasts
(SONCC)
Coho
Salmon
(Oncorhynchus kisutch) Evolutionary Significant Unit was listed as threatened under the
ESA on May 6, 1997 (62 FR 24588). The species was listed as threatened due to
numerous factors including habitat degradation, over harvest, water diversions, and
artificial propagation that have exacerbated the effects of natural disturbances such as
floods, drought, and poor ocean conditions. Designated critical habitat for SONCC Coho
salmon encompasses accessible reaches of all rivers, estuarine areas, and tributaries
between the Mattole River in California and the Elk River in Oregon.
Coho salmon exhibit a relatively simple three-year life cycle. Adult Coho salmon travel
from the ocean into river mouths traveling upstream. In non-winter months, many
California streams have sandbars that block the mouths of such rivers, and thus the entry
of adult Coho salmon typically occurs between September and February. The precise
timing of these entries is determined by the species history and by annual river flows.
Once upstream, spawning takes place. Spawning typically occurs from November to
January, but occasionally occurs as late as February or March. Coho eggs incubate for 35
to 50 days between November and March. The success of incubation is dependant on
several factors, including dissolved oxygen levels, temperature, substrate size, amount of
sediment, and water velocity. Fry begin to emerge from the gravel two to three weeks
after hatching and move into shallow areas with vegetative or other cover. As fry grow
larger, they disperse throughout their resident streams, both up and downstream. In
summer, Coho salmon fry prefer pools – or other slower velocity areas such as alcoves –
with woody debris or overhanging vegetation. Juvenile Coho salmon over-winter in slow
water habitat with cover as well. Juveniles may rear in fresh water for up to 15 months,
where after they migrate to the ocean as smolts from March to June. Coho salmon adults
typically spend two years in the ocean before returning to their natal streams to spawn as
three year- olds. While in the ocean, Coho salmon remain closer to their natal river than
do Chinook salmon.
62
Sensitive Species
The Tribe currently follows all conservation recommendations issued by the U.S. Fish &
Wildlife Service on all federally funded projects. Three sensitive species of wildlife exist
locally: Goshawk, Osprey and Golden Eagle. No Golden Eagle nests are known on the
Reservation, but the remaining two species have nesting populations of unknown size on
the Reservation.
Any operations in the vicinity of Osprey nests should be done during non-breeding
seasons (September–February). Goshawks depend on old-growth Douglas fir forests to
some extent and are therefore important indicator species for assessing the overall health
of Douglas fir stands. Goshawk habitat requirements have been studied locally by Pat
Hall, see Location and Identification of Essential Habitat for Goshawks (Accipiter
gentilis) on Six Rivers National Forest. Recommendations for this species include
maintaining closed canopy stands around nest sites, alternate nest sites, plucking sites and
roost sites. The protection zone should include coniferous stands contiguous with riparian
and open habitats.
Special Interest Species
Four special interest species occur on the reservation, Great Blue Heron, Sharp-shinned
Hawk, Cooper’s Hawk and Pileated Woodpecker. The first three of these species require
only protection around their nesting sites. The Pileated Woodpecker has some special
requirements in old growth forests, and is considered a culturally important species for
the Hoopa people. In a study performed in the Blue Mountains of Oregon, Evelyn Bull
(Master Thesis, Oregon State University, 1975) found the following optimum habitat
characteristics for Pileated Woodpeckers:
1) Snags greater than 16” diameter at 31’ above ground (greater than 20” dbh).
2) Two storied stands with 70% canopy closure.
3) Presence of Carpenter ants; therefore presence of logs with heart rot.
4) Stands large enough to contain 300-acre territories.
63
5) A density of snags above 7 snags/100 acres greater than 20” dbh in 100% forested
stands. A density of 12/100 acres in 60% forested areas.
6) At least 50% forested areas in territories. Pileated Woodpeckers were absent in
areas with 35% forested habitat.
Other Species
Species that are not endangered, but require special consideration include: steelhead,
sturgeon, eels, deer, elk and neo-tropical migrant birds. There are several fish stocks of
concern on the reservation. Surveys conducted by the Fisheries Department have focused
on the Trinity mainstem. The Trinity River currently contains Coho (Oncorhynchus
kisutch) in this Southern Oregon/Northern California Evolutionary Significant Unit,
which are listed as threatened species under the Federal Endangered Species Act (ESA)
(Federal Register. Vol. 62, No. 87). Klamath Mountains Province ESU Steelhead (O.
mykiss) and were formerly a candidate species for ESA listing (Federal Register. Vol. 63,
No. 53). Both species have been documented in the Trinity River and Reservation
tributaries.
Other fish species of cultural significance are green sturgeon and Pacific lamprey eels.
Green sturgeons are found mainly in the Trinity River and have reduced populations as a
result of the construction of the Trinity dam and regulated river flow. Pacific lamprey
eels frequent the mainstem Trinity River, as well as several tributaries on the reservation.
They are generally less abundant today than they have been historically due to degraded
habitat conditions. Protection of streamside zones from further encroachment of new
roads or development would aid in the maintenance recovery of the fisheries.
Vegetation
Natural resource subsistence is a very important aspect of contemporary Hoopa culture.
A majority of Hoopa Tribal members and their families rely on hunting, fishing, and
gathering to supplement their diets. Pursuant to Tribal law, ordinances have been written
which regulate resource uses for the fisheries, mushrooms, hunting and other gathering.
Given this extensive cultural reliance on the natural resources of the Hoopa Valley Indian
64
Reservation, concerns have been expressed by Tribal members to assure future access
and use of resources. According to the Cultural Resource Survey and Evaluation of
Portions of the Hoopa Valley Indian Reservation, Humboldt County, California (Sonoma
State University, David Fredrickson, 1982):
“interviews conducted to date with knowledgeable persons within the general
Northwestern California area have disclosed two major areas of cultural
resource concerns: (1) protection of and access to known traditional locations of
religious and ceremonial importance, and (2) protection and proper maintenance
of and access to natural resources especially those of importance in basketmaking and those with subsistence importance.”
Fredrickson further states “Concern was expressed by all individuals over the availability
and access to certain plant resources including food and nonfood items”. Of primary
concern is accessibility and protection of acorns, which are still an important part of the
diet of the Hoopa (Fredrickson).
Sensitive Species & Habitats
In 1986 only four (4) separate California sites were documented to contain populations of
Bald Hill Locoweed, a sensitive plant species, three of these sites were on the Hoopa
Valley Indian Reservation (Theiss, 1986). This species is found in disturbed soils along
roadsides in the Bald Hills area of the Hoopa Valley Indian Reservation. Any activity in
this upland area must consider impacts to this sensitive species.
2011 Hoopa Valley Tribe Botanical Update – Kimberly Davis, Botanist
Since 1986 there have been Botanical surveys conducted of the intended timber
harvesting areas on the Hoopa Reservation.
In accordance with the Hoopa Forest
Management Plan guidelines these surveys were conducted in order to identify, locate
and map any existing Threatened & Endangered plant species, any sensitive plant species
and any plant species of cultural interest and concern. In all of the surveys conducted not
one population of a listed Threatened & Endangered plant species was found within the
65
Hoopa Reservation Boundaries.
There have been numerous populations of listed
California Native Plant Society (CNPS) sensitive plant species and plants of cultural
interest and concern located. These have been mapped and the information on their
location is available from the Hoopa Tribal Forestry Department.
Agricultural Resources
Through the ages, the Hoopa’s superior hunting and fishing skills insured them a stable
food supply. They supplemented their diet with berries, acorns, chinquapin and pine nuts
gathered by the women. Little else was grown other than tobacco used for pipe smoking.
In 1890, about the time the government school was started, the Agency began to raise
crops in an effort to teach the Indians how to farm. Grains, mainly wheat and oats, were
the principal crops grown. Much of the land was cleared, houses were constructed of
mill-sawed lumber, and hogs, cattle and horses were raised. The Valley was especially
adapted to raising hogs, and by 1935 hogs were a very important source of cash income.
Besides raising hogs, cattle and horses, the Indians also raised chickens, turkeys,
waterfowl, goats, dairy cows, sheep and mules.
Agriculture uses in the Hoopa Valley include the cattle industry, the raising of feed crops
and subsistence gardening/orchards. Of the agricultural uses, raising cattle and the
growing of feed crops account for a significant economic sector of the local economy.
Several families utilize Big Hill, Bald Hill and occasionally Mill Creek Roads to drive
cattle to the summer grazing ranges in the high country of the Reservation or in the Six
Rivers National Forest where grazing permits allow for range access.
Timber Harvesting
Timber harvesting is the single most critical aspect of resource management on the
HVIR. The Tribe almost exclusively depends on the timber resources of the Reservation
for its income and employment opportunities. The timber industry in Hoopa is the single
largest sector of the Reservation economy. The Tribe has assumed all of the non-Trust
responsibilities of forest management on the HVIR under the Self-Governance
66
Demonstration Project. The Tribe prepared a Forest Management Plan (FMP) which was
subsequently approved on September 20, 1994 by the Bureau of Indian Affairs. This plan
covers the period of 1994 through the year 2008, and the plan was amended again on
March 22nd 2002. The purpose of the FMP is to manage the approximately 75,000 acres
of commercial timberland with an estimated volume of 1.2 billion feet of commercially
important timber. The annual timber harvest has impacts on both the Tribal economy and
the HVIR environment. The higher the harvest level, the more jobs created and the
greater the short-term income to the Tribe. Conversely, higher timber harvests disturb a
larger land area. In addition, increasing the Allowable Sale Quantity (ASQ) involves
bringing more acreage into intensive production, possibly affecting management of the
valley view shed, riparian areas, and Tribal reserves (both current and potential
additions). This ASQ increase in turn affects other natural resources of the Reservation,
and affects some site development areas that contain timber resources.
The Tribe has in recent years begun to incorporate the principles of new forestry into
their timber management operations. New forestry involves modifying timber
management activities to more closely resemble natural processes. Harvest techniques
include leaving harvest sites with some standing live and dead trees, large woody debris,
and corridors of residual trees. These practices can reduce the adverse effects to wildlife
from timber harvesting; however, they also create slash disposal problems, decrease
wood volume removed per acre, and increase the difficulty of regenerating conifers, all of
which may reduce both present and future income from timber. The use of “new forestry”
techniques involves the incorporation of integrated resource management planning.
Cultural Resources
Archaeological, Historic & Religious Resources
The locations of the dance sites, particularly the Chi dil ye’ (White Deerskin and Jump
Dance are of extreme importance. They are intrinsic to our beliefs of connecting to Me’
che kiwil di chwin il (ancestors/descendants) and the spiritual to ourselves. The
ceremonial sites themselves are part of our irreplaceable ceremonial locations identified
in the updating of this plan. Significant historical and cultural sites are abundant on the
67
Hoopa Valley Indian Reservation. Conservation and protection of prehistoric, historic
and contemporary sites are important to the people of the Hoopa Valley for historic,
religious, ceremonial, and subsistence purposes.
Surface investigations of approximately 23% of the timber producing land on the
Reservation have revealed at least 13 prehistoric sites. All have been assigned State of
California identification numbers. Findings at these sites range from sparse scatterings of
chipping debris to dense concentrations of artifacts. Recommendations for inclusion on
the National Register of Historic Places would require subsurface investigations. In
addition, the entire valley floor of the Reservation has been surveyed at a surface level.
Archaeological/ historical sites within the valley floor have been recorded and trinomials
have been issued.
The Hoopa Tribal cultural gill net fishery is managed by the Hoopa Valley Tribal
Fisheries Department, and is coordinated by Tribal Members family heads that control
fishing areas. The Trinity River fishery has been a cultural and subsistence mainstay of
the Hoopa people for thousands of years. The Tribe has and is harvesting from the Tribal
allocation of in-river salmonids runs that are headed for the upper reaches of the
watershed. The vast majorities of fish migrating through the Reservation do not spawn
within the Reservation, but spawn further up in the basin
The People of Hoopa Valley are one of California’s first cultures. The first American
trappers and gold miners entered Hoopa in 1828. They came up the Trinity River into the
rich valley which has always been the center of the Hoopa World, the place where the
trails return. Legends say this is where the people came into being. Our treaty was signed
providing the whole Hoopa Valley as a reservation. In 1876 an executive order was
signed acknowledging this treaty. Since first European contact the culture and traditions
remain to this day.
In 1864, a Peace and Friendship Treaty was negotiated with the United States. In 1896,
the Department of the Interior began preparing a land allotment list and in 1909 a
68
Proclamation was handed down by President Theodore Roosevelt. This list was not
completed and approved until 1923. The Hoopa People successfully avoided the physical
destruction of their valley homeland, and in modern times created one of the first
successful Self-Governance Tribal structures in the nation.
The Hoopa people traditionally occupied lands in the far northwestern corner of
California. The boundaries of the reservation were established by Executive Order on
June 23, 1876 pursuant to the Congressional Act of April 3, 1864. The boundaries were
expanded by Executive Order in 1891 to connect the old Klamath River (Yurok)
Reservation to the Hoopa Valley Reservation. Further confirmation of the ownership by
the Hoopa Tribe of the Hoopa Valley Reservation came on October 31, 1988 with
President Ronald Regan’s signature on Public Law 100-580, the Hoopa/Yurok Settlement
Act.
The Hoopa hold several ceremonial dances during separate parts of the year and usually
for different purpose. The White Deerskin Dance and Jump Dance is considered a world
healing ceremony where balance can be brought back to the Hoopa people, and is held in
the late summer every other year. The Brush Dance is more of a social dance where a
medicine man and woman are charged with praying for a sick or new child. There are
also coming of age dances for young women called the Flower Dance. All of our
ceremonies have been practiced for thousands of years and are meant to ward off evil,
such as disasters to our lands or droughts and famines, while at the same time bringing
our people together to celebrate our culture and strengths.
Socioeconomic Conditions
The 2000 U.S. Census indicated that there are 2,633 people residing on the Hoopa Valley
Indian Reservation. 2000 Census survey data indicates the median household family
income for Reservation residents was $23,384. The unemployment rate on the Hoopa
Valley Indian Reservation is 14 percent, and 29 percent of families, and 39 percent of
individuals residing on the reservation are below the poverty level. 46.4 percent of
69
families with a female householder and no husband present are below the poverty level
(U.S. Census, 2000).
Seasonal tourism, logging, the school district, tribal operations, the Federal government,
and the private sector provide most of the employment opportunities on the Reservation.
By January 1981, all five lumber mills that once existed on the Hoopa Valley Indian
Reservation had either closed down or had relocated to other areas. This situation is
largely due to the declining timber industry in Humboldt County.
The Hoopa Valley Indian Reservation is currently experiencing an extreme economic
depression. In years past, the Reservation population has been significantly dependent
upon the logging and timber production industry for non-professional employment
opportunities. However, in recent years, over production, increased automation, and
environmental impact priorities have crippled the timber industry. The lumber mills on
the Reservation that once employed many Tribal people have been shut down.
The available employment opportunities in the field of logging have been reduced by
approximately 85%. The Hoopa Valley Indian Reservation represents an isolated pocket
of extremely high unemployment. Recent analysis of the situation indicates that access to
employment is a major problem. The nearest job market for residents of the Reservation
is a more than 120 mile roundtrip commute to the Eureka/Arcata area. The age
distribution of Reservation residents indicated in the 2000 Census presents a dynamic
trend to rapid growth due to the median age of 26 years. As the level of growth increases,
so will be the demand for Tribal resources.
In projecting population growth and therefore the projected need for housing,
infrastructure, and related sociological factors, the conventional planning technique and
process will not work effectively in the Tribal spatial environment. For the purposes of
this plan, the assumption has been made that the projected population growth will
increase by 29.8 percent in the next decade. For this reason, projected Tribal resource
demands have been projected to increase at 5 percent per year for the next decade.
70
Attitudes and Expectations
Tribal government on the Hoopa Valley Indian Reservation is being dramatically
changed due to the Tribe’s designation as a Self-Governance Demonstration Tribe in
1988. Since designation, the Hoopa Valley Tribe entered into a “Compact” with the
United States government in July, 1990 pursuant to Title III of P.L. 100-472. Thus, in a
little more than ten years, the Hoopa Tribe has moved from a position of being one of the
most regulated tribes controlled by the United States to a position of freedom from such
regulation unprecedented among Indian Tribes. This radical change of circumstance has
had a considerable effect on all branches of Hoopa Tribal Government including Hazard
Mitigation and Planning.
Community Infrastructure
General Overview
The business sector of Hoopa includes a restaurant, delicatessen, fast-food restaurant, gas
station, auto repair shop, office supply store, credit union, an independent logging
company, Supermarket, and a self-storage facility. Community facilities housed in the
Neighborhood Facilities Center include the Tribal Recreation, Day Care Programs, Tribal
Administrative, and the Tribal Council. Adjacent buildings house the Public Utilities
District,
Senior
Meals/Volunteer
Program,
Hoopa
Housing
Authority,
Adult
Education/Career Center, and the Tribal Education Center. The Tribal Shopping Center
houses the Tribal Museum, Radio Station, grocery store, Hoopa Tsewenaldin Motel and
Lucky Bear Casino. Private vehicle transportation is required for virtually all travel.
Klamath Trinity Non Emergency Transportation (K/T NET) commenced transit
operations in January 2003. K/T NET is a nonprofit community based organization in
eastern Humboldt County which provides transit services in underserved areas, including
tribal lands in Hoopa, with connections to other existing transit systems, such as
Humboldt Transit Authority. The nearest commercial air service is 65 miles away. There
is only one paved road (Highway 96 between the Reservation and other population
centers. The Tribal Radio Station, KIDE FM, (a 250-watt educational facility, the only
Indian owned and operated radio station in California) began broadcasting in December
71
1980. Other radio and TV reception is poor to fair because of the mountain ranges
between the nearest transmitter (in Eureka/Arcata, 65 miles away) and the Reservation.
Fire Protection
The Hoopa Fire Department provides primary wildland suppression responsibilities for
the Hoopa Valley Indian Reservation. Department staff is comprised of a Fire
Management Officer (Fire Chief) and two Division Chiefs, one Operations and one
Prevention Chief. The department is supported administratively with an Office Manager
and a Fire Clerk/Receptionist, all full time employees. The Hoopa Fire Department
facility and grounds are designated as a location for an Incident Command Post and
Primary EOC.
Currently the department staffs 3 (three) Type III Urban interface engines, 5 (five) person
effective throughout the summer. These engines crews are lead by permanent Fire
Captains that work year around. As funding becomes available the department will be
increasing its permanent staffing to eventually staff 6 (six) engines with a minimum of 5
person staffing. Fire planning effort is supposed to eventually provide us with 3 Type III
engines, 3 Type IV engines and 2 (two) Type I water tenders. (Resource typing is per ICS
resource typing standards.) Currently the department has 4 Type III engines, 1 Type 4
engine, 1 Type 6 engine and 1 Type I Water Tender, though all apparatus is not staffed
due to the limiting factor of funding.
All department employees are ICS trained and qualified under NIIMS (National
Interagency Incident Management System) standards and is functioning at various levels
from introduction to ICS through Advanced Incident Management. Several department
members are attached to Local and National Incident Management Teams and/or are
trainees, Incident Commander and at the Command and General Staff level as Section
Chiefs.
Due to the seasonal nature of wildland fire suppression the majority of the resources are
themselves, seasonal in nature; however there is never a month during the calendar year
72
that the reservation has not experienced a wildland fire based on favorable weather
conditions for fire to burn. During periods outside what is normally viewed by the public
as “out of fire season” the department still maintains a “skeleton crew” to staff an engine
365 days a year. Our organization is frequently requested to provide suppression
resources for incidents off of the reservation and we have provided suppression resources
to other geographical locations throughout the country during any month of the calendar
year.
The Hoopa Volunteer Fire Department provides structural fire protection and responses
to “All Risk” incidents as such their services are rated by an independent insurance
ratings service for Hoopa Valley Tribal Insurance purposes. The Insurance Services
Office (ISO) designates public protection classification. The ISO bases its classifications
on a number of factors, including fire department location, equipment, and staffing; water
supply; and communications abilities. Ratings range from 1 to 10, with 1 being the best
possible fire protection, and 10 being the worst. The Hoopa Valley Indian Reservation is
classified with a rating of 7. In areas where access to water is limited, for example fire
suppression, the water must be trucked in.
Law Enforcement
The HTPD reviewed the 2011 Multi Hazard Mitigation Plan Law Enforcement section
and at this time there are no chances required by the Department. The Hoopa Tribal
Police Department during the several Incidents on the Hoopa Valley Indian Reservation,
continue to provide a Law Enforcement presence. Additional Patrol Officers are called
out to provide extra coverage depending on the Incident. In the unincorporated areas of
the County, the Humboldt County Sheriff’s Department provides limited law
enforcement due to State budget cuts. The Hoopa Valley Tribe is exploring Federal Law
Enforcement assistance for additional training and officers. The County maintains a
Sheriff Department sub-station and jail on the Reservation. In nearby Willow Creek, the
California Highway Patrol maintains a field office.
The Hoopa Valley Tribe is one of only a handful of Tribes in California that operate a
Tribal Police Department. The Tribal Police Department is subject to the same training,
73
policies and procedures as any municipal police department and through a landmark
agreement with the Humboldt County Sheriff’s Department and most Officers have been
cross-deputized as Sheriff Deputy’s. In addition, the Tribe exerts law enforcement
jurisdiction on trespass involving timber and fisheries by providing Resource Protection
Officers.
KIDE Radio Station FM 91.3
The local KIDE FM Radio station plays a major role in educating the community and in
the notification of emergency evacuation as part of the Office of Emergency Services
Whelen Warning Sirens Systems Notification. As part of the Evacuation Alert Protocol
all community residents will tune into KIDE FM 91.3 when they hear the Warning Sirens
alert to determine what type of emergency notification and what they are instructed to do.
This Evacuation Alert Protocol will require extensive community education and monthly
sirens testing and annual community drills
Schools
The Klamath-Trinity Unified School District Transportation Coordinator participated in
the 2011 MHMP Update planning process and indicated no changes in specific planning
and evacuation protocols. The Klamath-Trinity Unified School District encompasses both
the Reservation and surrounding areas, with district offices and elementary and high
schools located in Hoopa. The Klamath- Trinity Unified School District serves a total of
1,076 students. The school district has primary responsibility for education through high
school. The Hoopa Valley Elementary School has 440 students, 91.1% of whom are
Indian. The Hoopa Valley High School has 267 students, 69.7% of whom are Indian.
This data is from the 2003-2004 school year and comes from the California Department
of Education Educational Demographics Unit.
Solid Waste Disposal
Solid waste management is a serious problem on the Reservation. The Tribe once
operated a modified landfill near the Supply Creek drainage to serve the Tribal
Membership. This landfill has reached capacity and was closed by the Tribe in October
1998. Currently, solid waste is being disposed of at the Tribe’s transfer facility located in
the center of the valley on Highway 96. The Hoopa Valley Transfer Station is operated
74
by Hoopa Valley Public Utilities District. The proposed undertaking is not expected to
impact solid waste management on the Reservation.
Telephone
Verizon (formerly GTE) provides telephone service to the Reservation. Local ISP
providers now provide a local Internet exchanges. The Hoopa Tribe rents a T1 line for
tribal entities, however there is still a need for valley wide high speed internet. The Tribe
installed a cellular tower in the Bald Hills area in 2004 and cell phone coverage is now
available to Reservation residents.
Gas and Electric
Pacific Gas and Electric provides electrical service to the Reservation. Underground
natural gas is not available on the Reservation. Amerigas and Campora two local propane
gas providers provide propane gas service.
Water and Sewer
The Hoopa Valley Public Utilities District (HVPUD) provides municipal water service to
92 percent of the Reservation residents. The balance of the population obtains water from
individual wells and springs, these water sources may have been intermittent and of
dubious quality in the past, but since the installation of the Hoopa Valley Wide Water
Treatment facility, water has been consistent throughout the year. The Hoopa Valley
Public Utilities District aims to increase the access to safe reliable domestic water on the
Reservation. Plans are in progress to construct a sewer treatment facility to handle the
Hoopa Valley waste issues.
2007 Severe Storm Event
According to the original survey and project plans the Water Treatment Plant is at a
benchmark elevation of 333 ft., while the river is ~300 ft. Any significant rise in river
levels above +30 ft. (Severe, Major) would begin to inundate the building structure, tanks
and distribution pumps. Above that +30 level we can expect significant damage to occur.
Should the Water Treatment Plant become a total loss, or should the Plant be nonfunctional for an extended period of reconstruction/repair, the Telescope Treatment Plant
(el. 693’) would be utilized to provide treated water. However, this source would be
75
limited in capacity and conservation measures would need to be in place until such time
as the main Plant can be put back into operation. Distribution infrastructure could also be
damaged, for example, the water main river crossing under the Hwy 96 bridge. The loss
of this crossing would isolate eastern portion of the Valley from available potable water.
District structures have been constructed to applicable building codes at the time of
construction, however seismic standards are subject to amendment over time. Piping
infrastructure and storage tanks would most vulnerable to a significant seismic event.
Older pipelines, such as AC piping installed by IHS, would suffer the most damage. It is
difficult to determine what damages would occur to the system in the event of a major
seismic event. The only solution to this type of damage would be to isolate affected areas
and begin repairs.
Resource Use Patterns
Hunting, Fishing, & Gathering
Natural resource subsistence is a very important aspect of contemporary Hoopa culture.
A majority of Hoopa Tribal members and their families rely on hunting, fishing and
gathering to supplement their diets. Pursuant to Tribal law, ordinances have been written
which regulate resource uses for the fisheries, mushrooms, hunting and other gathering.
Timber Harvesting
Timber harvesting is the single most critical aspect of resource management on the
Hoopa Valley Indian Reservation. The Tribe almost exclusively depends on the timber
resources of the Reservation for its income and employment opportunities. The timber
industry in Hoopa is the single largest sector of the Reservation economy.
The Tribe has assumed all of the non-Trust responsibilities of forest management on the
Hoopa Valley Indian Reservation under the Self-Governance Demonstration Project. The
Tribe prepared a Forest Management Plan (FMP) which was subsequently approved on
September 20, 1994 by the Bureau of Indian Affairs. This plan covers the period of 1994
through the year 2010. The purpose of the FMP is to manage the approximately 75,000
76
acres of commercial timberland with an estimated volume of 1.2 billion feet of
commercially important timber.
Agriculture
Agriculture uses in the Hoopa Valley include the cattle industry, the raising of feed crops
and subsistence gardening/orchards. Of the agricultural uses, cattle production, and the
growing of feed crops account for a significant economic sector of the local economy.
Several families utilize Big Hills, Bald Hills and occasionally Mill Creek Roads to drive
cattle to the summer grazing ranges in the high country of the Reservation or in the Six
Rivers National Forest where grazing permits allow for range access.
2011 Update Local Food Sustainability – Community Emergency Preparedness
Although agricultural uses in the Hoopa Valley is no longer as economically significant
as in the past, the Valley is almost perfect for the growing of food crops, with superior
soils, available water and a long frost free growing season. The trending towards organic
and de-industrialized food systems bodes well for development of economical
agricultural enterprises, and expansion of subsistence production to meet local needs.
Unfortunately, more than half of the acreage has been developed for other purposes and
the remaining areas are much subdivided, overgrown with invasive plants and vulnerable
to housing pressure. In 2007, the Hoopa Valley Tribe became the first tribe in California
to form a Tribal Resource Conservation District, to serve as advocates for agriculture,
conservation and food systems issues. This tribally-chartered non-profit organization, the
Klamath Trinity Resource Conservation District, works under as MOU with the Hoopa
Valley Tribal Council and has been successful in building partnerships with USDA
agencies to assist local farmers and ranchers. One major project is an upgrade to a portion
of the BIA-era irrigation system that will result in more efficient, reliable and abundant
agricultural water supply to properties on the east of the Hoopa Valley. Funding and
technical assistance for the project was provided by a cost-share agreement between
Natural Resources Conservation Service and the Hoopa Valley Tribe. Project work has
been carried by the Hoopa Valley Public Utilities District. The KTRCD and NRCS have
also implemented a Local Food Policy Council, a fruit tree inventory, a community
77
garden, a farm-to-consumer direct marketing program, a tractor loan program and
technical assistance to individual landowners.
Land Use Patterns
The Hoopa Valley Indian Reservation is comprised of 93,702.73 acres with 88,840 acres
held in tribal trust, 2,947 acres allotted to tribal members, and 1,968 acres in fee or
government use status. It should be noted that the term fee status includes lands owned by
Tribal members in fee, non-Indian fee lands, and in some case fee lands owned by the
Hoopa Valley Tribal Council.
In addition, the Hoopa Valley Tribal Council owns 224 acres of fee lands outside the
reservation. Of the Reservation’s total gross acreage 48,332 acres is regarded as the forest
component available for intensive forest management, 29,137 acres is designated as
special or limited management forest zones. The balance or 16,233.73 acres is unsuitable
for forest management because of landslide potential, cultural use or residential,
commercial, and agricultural uses.
Approximately 2% of the Hoopa Valley Indian Reservation lands are in fee status. The
Reservation fee lands were at one time allotted land upon which a fee patent was issued.
Most, but not all, of this land is “alienated” --owned by non-Indians. The Hoopa Valley
Tribal Council has either purchased or has been gift deeded 600 acres of land that once
was in fee status and in some cases has retained the fee status for various reasons.
Recreation
Recreation opportunities on the Hoopa Reservation include areas designated for specific
active recreational uses such as swimming, fishing, boating and camping. Two types of
recreational levels exist; one for the local resident Indian population and one for the
occasional tourist. The adoption of the Wild and Scenic Rivers Act (16 USC 1273) has
classified the Trinity River as recreational river from the southern boundary of the
Reservation to a location approximately opposite Carpenter Lane. From Carpenter Lane
to the confluence of the Trinity with the Klamath, the designation is scenic with the short
78
segment of the Klamath River within the Hoopa Valley Indian Reservation classified as
recreational.
Transportation Network
State Highway 96, which runs north/south through the center of the Hoopa Valley, is both
the principal road within the valley and the chief access route to areas outside the
reservation. Highway 96 connects to U.S. 299 at one extreme and Interstate 5 at the other.
The only other road providing year round access is Bair Road, which ties into U.S. 299.
Other roads leading out of the valley are unimproved forest access roads.
The Hoopa road system conforms to the natural topography of the area. Various loop
roads off of Highway 96 provide access to residential and commercial development on
the valley floor and within the low-lying hills. Access to Reservation timberlands and
spur roads off Highway 96 provide access to adjacent national forest land or other valley
roads.
Along with Highway 96 there are 4 major evacuation routes through major arterial roads
off the Hoopa Reservation. On the Northeast corner, both Big Hill Road and Mill Creek
road lead to Red Cap Road which will lead you to Orleans area. To the Southeast is TishTang Road which leads to Horse Linto Creek Forest Service area and the Willow Creek
area. The Northwest evacuation route is the Bald Hills Road and Dowd Road which lead
to either the Weitchpec area or across to Orick area on the Pacific Coast. Finally the Bair
Road or Supply Creek Road will lead to the Redwood Creek area and eventually to
Highway 299 which can go back towards Willow Creek or out to Arcata/Eureka area
along the coast. These four main roads will be prioritized to maintenance in order to be
kept clear for emergency situations. Also they will be properly signed and publicized as
evacuation routes during emergency preparedness public outreach.
Humboldt County currently maintains an airstrip on the Reservation. This airstrip,
located on Matilton Field, can accommodate only small non-commercial aircraft. The
nearest commercial air service is 65 miles away. State, County, BIA, and Tribal Roads
serve the Hoopa Valley Indian Reservation. The Tribe has contracted road maintenance
79
and betterment from the BIA and is responsible for road maintenance activities of BIA
roads.
Mining
Both lode and placer deposits have been mined successfully on the Hoopa Reservation in
the past, with sand and gravel provided for local use. The Reservation has some potential
making use of copper deposits (including by-product gold and zinc), mercury lode
deposits, and for the recovery of gold and platinum from placer deposits. Resources of
sand, gravel, and stone are large, but their use depends on local requirements. Small or
low-grade deposits of manganese, chromite, coal, and graphite also exist on the
Reservation.

Chapter 3 – Natural and Human Caused Hazard Risk Assessment
Introduction
Effective hazard mitigation planning requires, as in depth as possible, knowledge of and
about the potential natural and human caused hazards which pose a threat to a
Community, its people, structures and infrastructure. Knowledge about these hazards is a
necessary element to the development of effective hazard mitigation strategies to limit
and/or prevent the loss of life and/or damage to structures and infrastructure. Because of
the limits to the knowledge about certain potential natural and human caused hazards,
there is a greater uncertainty in assessing the risk posed by these hazards. To the extent
then possible the natural and human caused hazards which pose a possible threat to the
health, welfare and safety of the Hoopa Valley Indian Reservation are assessed in this
section of the Hoopa Valley Indian Tribe’s Multi Hazard Mitigation Plan (MHMP).
The Hoopa Valley Indian Reservation faces the threat from several natural hazards
among these are Dam Failure, Earthquake, Drought, Flood, Severe Storm, Landslide, and
Wildfire. The Tribe also faces threat from certain human caused hazards such as; air
quality pollution from illegal burning of household garbage and construction materials,
chemical spill, arson, etc. To effectively assess the risk from these hazards the
Reservation has been divided into three hazard risk assessment areas, Urban, Upland
Residential, and Upland (see Map A). The Urban Area comprising all of Hoopa Valley
proper and includes approximately 85% of the populated area of the Reservation with
associated structures, infrastructure, and all Tribal government departmental offices. The
Upland Residential Area is located in the Bald Hill region of the Reservation and
includes approximately 15% of the Reservation’s population residing in a dispersed
pattern of residential development. The Upland Area is the largely unpopulated
mountainous region of the Reservation and the location of the majority of the Tribe’s
cultural, wildlife, and timber reserve areas.
The Natural and Human Caused Hazard Risk Assessment Chapter is divided into 9
sections. Following the Introduction, the initial section (3.1) is a brief description of the
81
methods used to identify the natural and human caused hazards in each assessment area
plus methods used to assess vulnerability. The following 7 sections address each natural
and/or human caused hazard of concern on the Hoopa Valley Indian Reservation. A
description of past events, an assessment of vulnerability, and potential losses are
discussed for each hazard. The hazards are discussed in alphabetical order not in an order
of ascending or descending of severity of risk or vulnerability.

Hazard Identification and Vulnerability Assessment Methods
In the 2011 MHMP Update planning meetings the Local Emergency Management
Committee (LEPC) determined there were not new identified Hazard Risk Assessment
Probabilities, Vulnerabilities or Impacts in the 2011 MHMP Update discussions and
review of recent local events, state and federal disaster designations. Including, regional
hazard information prepared by state, and federal agencies and internet web sites
containing local and regional hazard information. Originally in 2006 when developing the
hazard identification and vulnerability assessment methods the Local Emergency
Planning Committee (LEPC) took the following steps to identify hazards that have
affected the Reservation in the past and/or can be expected to affect the Reservation in
the future:
•
Review of past state and federal disaster designations
•
Review of regional hazard information prepared by state, and federal agencies
•
Review of Internet web sites containing regional hazard information
The seven main natural and human caused hazards that have affected the Reservation in
the past and/or could affect the Reservation in the future are dam breach, drought,
earthquake, flood, landslides, severe storm event, and wildland fires. In addition to these
hazards, other potential hazards such as tsunamis, tornados, and hurricanes where also
evaluated, but found to pose no real threat to the Reservation due to our location and
weather patterns. As a result of the literature described above and a draft review of the
Hoopa Valley Indian Tribe Emergency Operations Plan (EOP), all of the above natural
hazards are assessed in this plan with the exception of hazards not commonly recognized
as threats to the Tribe, as noted.
Information acquired from the materials listed above was also used to estimate the
vulnerability of the Reservation assessment areas to each hazard (see Tables 6 & 7 and
Map B). This information included the probability of occurrence of hazard events, the
types of damage associated with a hazard, and the relative vulnerability of each
84
assessment area. After compiling this hazard information, areas of the Reservation
vulnerable to the hazards were identified. The estimated relative levels of vulnerability
for each hazard assessment area were based on the following factors:
•
Probability of damage resulting from a large hazard event;
•
Types of damage associated with the hazard;
•
Historic and/or potential severity of damage;
•
Potential damage relative to other hazards; and
•
Vulnerability of each area relative to other areas within the Reservation.
The relative probability of hazard occurrence (between hazards) is not reflected in the
vulnerability assessments. For example, although the Urban Area was rated as having a
high vulnerability to both floods and earthquakes, it is much more likely to be affected by
floods. The ratings for each hazard therefore reflect the estimated vulnerability if a large
hazard event occurs. In addition, the amount of development in each assessment area was
not factored into the estimated vulnerability for an area. For example, although the
Upland Residential and Urban areas have very different levels of development, they have
the same estimated earthquake vulnerability. Different levels of development are
reflected in the estimated potential losses for each area; highly developed areas have
greater potential losses.
The following table explains the hazard/threat frequency measurement scale used to
determine the probability or how likely a hazard is to impact the community. Frequency
distributions measure the community’s exposure to a hazard, as shown in the table.
85
Exposure
Frequency
Highly Likely = 3
The potential for impact is very probable
(near 100%) in the next year.
Likely = 2
The potential for impact is between 10%
and 99% within the next year or there is at
least one chance of occurrence within the
next 10 years.
Possible = 1
The potential for impact is between 1 and
10% within the next year, or there is at
least one chance of occurrence in the next
100 years.
Unlikely = 0
The potential for impact is less than 1% in
the next 100 years.

Table 9 – Hazard Risk & Extent Assessment for Hoopa Valley Reservation
As you can see in Table 6, hazards are analyzed by risk and extent between the three
hazard assessment zones (Urban, Upland Residential, and Upland Region) and rated on a
scale of High, Low or None or similarly Wide, Limited, and N/A. In an effort to identify
highest priority to the Hoopa Tribe a combination of Risk and Extent was considered and
the Hazards are given specific actions within Chapter 4, the Mitigation Planning section.
Also a STAPLEE form was completed with all the hazard mitigation actions and ranked
according to Hoopa Tribal Priority and can be found in Appendix A.

Table 10 – Hazard Risk Occurrence Assessment for Hoopa Valley Reservation
Table 7 shows by occurrence and probability of reoccurrence between the three hazard
assessment zones (Urban, Upland Residential, and Upland Region) and rated on a scale
of Frequent, Infrequent or N/A or similarly High, Low, and N/A. In an effort to identify
highest risk to the Hoopa Tribe, a combination of Table 6 and Table 7 were considered
and the Hazards are given specific actions within Chapter 4, the Mitigation Planning
section. Also a STAPLEE form was completed with all the hazard mitigation actions and
ranked according to Hoopa Tribal Priority and can be found in Appendix A.

Dam Failure and Subsequent Flooding
The Trinity River, which flows through Hoopa Valley on the Reservation, has two major
dam structures the Lewiston Dam and the Trinity Dam located approximately 95 and 102
miles respectively, upstream from the Reservation (see Map C). These two dams
impound approximately 2,462,400 acre feet of water at capacity, of this total 14,700 acre
feet is impounded by Lewiston Dam in Lewiston Lake and 2,447,700 acre feet by Trinity
Dam in Clair Engle (Trinity) Lake. Both dams are earth filled dams constructed in the
early 1960’s by the Bureau of Reclamation as part of The Central Valley Water Project in
California. The Trinity Dam is the larger of the two dams with a structure height of 530
feet to Lewiston Dam’s 91 feet.
The two dams are located in the Klamath Geologic Province of Northern California,
which is seismically fairly stable. However there exist the potential for a magnitude 8.99.0 earthquake with an epicenter on the Cascadia Subduction Zone some 245 miles west
of the two dam sites or a series of moderate to high magnitude earthquakes caused by
eruptive activity of Mount Shasta, a historically active volcano, 52 mile Northeast of
Lewiston and Trinity Dam sites. These two sources of potential seismic activity pose a
threat to both dams.
The release of energy from an 8.9-9.0 magnitude Subduction Zone earthquake or a series
of 6.0-7.0 eruption related earthquakes could sufficiently weaken the structural integrity
of either the Lewiston or Trinity Dam to the point of failure. The failure of the Trinity
Dam would instantly release the 2,447,700 acre feet of water impounded by the dam in
Clair Engle Lake. The waters of Clair Engle Lake would surge downstream flow into
Lewiston Lake and breach the Lewiston Dam. The combined waters of Clair Engle and
Lewiston Lakes, some 2,462,400 acre feet would then surge down the stream channel of
the Trinity River as a wave front exceeding at time 150 feet in height and at a velocity of
approximately 15 miles/hour. At this rate the wave front would take approximately seven
hours to reach Hoopa Valley on the Reservation (see Map C).
The surge of water flowing down the Trinity River channel from the breached Trinity and
90
Lewiston dams would completely inundate the Hoopa Valley to an average depth of
approximately 225 feet above the current Hoopa gage datum of 274.82 feet. At this depth
all structures and infrastructure located on the floor of Hoopa Valley would be inundated
and would suffer near total destruction from the force of the wave front as it passed
through the valley (see Map D).
Highway 96 the principal access to and egress from Hoopa Valley would be severely
impacted by the flood waters surging down the Trinity River channel from a breach of
Trinity and Lewiston dams. Major sections of the highway, both North and South of
Hoopa Valley would be destroyed making Highway 96 impassable eliminating it as a
variable emergency route for evacuations or relief efforts. Although immediate relief
could be somewhat of an option if this worst case scenario were to occur, as the wave of
water would completely destroy every town between Lewiston and the Mouth of the
Klamath River creating one of the worst tragedies on US soil over the past century.
It is not unreasonable to expect near 100% lost of all structures and infrastructure in
Hoopa Valley caused by the wave front and inundation of the flood waters produced by a
breach of both the Trinity and Lewiston dams. According to USBOR Models and
calculations, it would take the wave front approximately seven (7) hours to reach Hoopa
Valley therefore; there would be adequate time to evacuate the entire resident population
thus reducing the probability injuries and/or deaths to near 0%.
Past and Probability of Future Dam Breach/Failures
Prediction of a dam breach based on past occurrences is in this case not possible since
nether dam has failed since construction. The probability of both the Trinity and
Lewiston dams breaching is extremely low. Both dams were constructed in the early to
mid 1960’s and as such the design criteria and construction of the dams took in to
account the potential seismic activity of the area. In addition both dams are continuously
monitored by the Bureau of Reclamation for their structural integrity thus early signs of
potential failure would be noted and remedial and corrective action taken. There has
never been an occurrence of a dam failure in our region in documented history.
91
Potential Dam Breach and Flood Losses
The recover period from such catastrophic events of a dam breach and ensuing flood
would be lengthy. Requiring a number of years to rebuild the Hoopa Valley community
and costly in terms of the amount of monies necessary to pay for the recovery. Given the
length of time for recovery and its high cost, it’s fortunate the hazard posed by a dam
breach on the Trinity River has a very low probability. Table 8 lists the flood
vulnerabilities and potential losses of structures to a dam breac
