Section 4 - Projected Impacts from Hazards on the Umatilla Indian Reservation

This section of the UIR Hazard Mitigation Plan takes the information in the Plan’s risk assessment in Section 3 one step further. It responds to a number of hazard mitigation planning requirements. This section: (1) identifies “the hazard area” for each hazard; (2) provides a list of critical facilities, and tribe-owned and operated assets impacted by identified hazards; and (3) contains an overview and analysis of potential losses to identified structures and assets for certain hazards where information was available . Included in the overview of potential losses are estimates of potential dollar losses from the hazards as determined by the TERC.

(1) Identified Hazard Areas

The “identified hazard areas” for each hazard are described using the descriptions and maps below:

1. Epidemiological Disasters – The entire UIR, but primarily places with the greatest concentration of people such as the Wildhorse Casino and Resort, schools, Elizabethan Manor, Yellowhawk Clinic.
2. Severe Winter Storms – The entire UIR
3. Wildfires – The entire UIR, but primarily areas located outside the immediate Mission Community (the most populated portion of the reservation that is protected by the CTUIR Fire Department). The possibility of a grassland wildfires and wheat fires exists for the lands at the base of the Blue Mountains.

The forested areas outlined in red on the map below are the most vulnerable to wildfires on the reservation.

4. Fog- for the identified hazard areas, see the map below:

5. Drought – The entire UIR
6 Flooding – For the identified hazard areas see the maps in Appendix __
7. Dam Failure – The identified hazard area that would be primarily affected by an Indian Lake Dam failure is the city of La Grande (which is located outside the UIR) as identified by red lines on the map below:

8. Dust Storms – Primarily the valley areas at the base of the Blue Mountains – See Map
9. Spring/Summer Storms – The entire UIR
10. Earthquake - The entire UIR
11. Wind Storms – The entire UIR
12. Landslides – The populated areas of UIR are not significantly affected by landslides although landslides do occur on the reservation. See the map below (also located in Appendix H):

13. Man-Made Disasters – - CSEPP area – The UIR is not in the CSEPP danger zone - See map and arrow identifying Pendleton which is west of the UIR.

- Hazardous Material Spills – In the unlikely event of a hazardous material spill, it would probably occur along one of the routes identified on the following map. Safety distances for a number of hazardous materials are identified on the map below for rail and highways near UIR’s populated areas:

- Gas Pipeline Disaster – Most of the UIR would not be affected by a gas pipeline break. If a break were to occur, the hazard area would be in the immediate vicinity of the gas pipelines identified on this map.

14. Volcanoes – The UIR is not in the danger zone for volcanic events. But if a small amount of ash were expelled from a Cascade Mountain Range volcanic event, it would be deposited on the entire UIR.
15. Extreme Heat – The UIR is not in a danger zone for extreme heat. Heat that occurs during summer and early fall affects the entire UIR.

(2) Critical Facilities and Assets Impacted by Hazards

After determining which hazardous events can impact the UIR in Section 3, the TERC inventoried assets located on the reservation and then, at a regular TERC meeting, made a link between the identified hazards and the critical facilities, tribal assets, and resources that could be impacted. In making that determination, the TERC considered responses to the following questions:

Two tables, which follow, help answer many of these questions. The Table 1 presents most of the significant assets located on the Umatilla Indian Reservation. Where information was available about the year a building was constructed, its replacement value and building type, it is presented in the table. In some cases, the Tribe acquired some of these structures, so information regarding the year of construction was not readily available.

Table 2 identifies the critical facilities, infrastructure, economic assets, cultural – historic assets, and environmental assets that could be impacted by the hazards listed in the table. In each column under a specific hazard, the type and level of damage to each asset from each hazard is identified by the following letters:

Possible Impacts

S = Structural Damage

E = Economic Loss

D = Disruption of Services

I = Injury/death

A = Likely Emergency Response from Tribe

C = Cultural Loss

H = Environmental and Habitat Damage

R = Recreational Loss

m = Damage most likely to be major

n = Damage most likely to be minor
