Administration that provides flood profiles and the water surface elevation of the Base Flood.
Floodway: The channel of a river or other watercourse and the adjacent land areas that must
be reserved in order to discharge the Base Flood without cumulatively increasing the water
surface elevation by one tenth of a foot.

Green Infrastructure: Use of natural or human-made hydrologic features to manage water and
provide environmental and community benefits. Green infrastructure uses management
approaches and technologies that use, enhance, and/or mimic the natural hydrologic cycle
processes of infiltration, evapotranspiration, and reuse. At a large scale, it is an interconnected
network of green space that conserves natural systems and provides assorted benefits to human
populations. At a local scale, it manages stormwater by infiltrating it into the ground where it
is generated using vegetation or porous surfaces, or by capturing it for later reuse. Green
infrastructure practices can be used to achieve no net loss of pervious surfaces by creating
infiltration of stormwater in an amount equal to or greater than the infiltration lost by the
placement of new impervious surfaces.
Habitat Restoration Activities: Activities with the sole purpose of restoring habitats that have

infiltration and increases the amount and rate of surface water runoff, leading to erosion of
stream banks, degradation of habitat, and increased sediment loads in streams. Such surfaces
can accumulate large amounts of pollutants that are then “flushed” into local water bodies
during storms and can also interfere with recharge of groundwater and the base flows to water
bodies.
Indian Health: Means the Indian Health Service of the U.S. Public Health Service.
Junk Yard: A place where waste, discarded or salvaged materials are stored, bought, sold,
exchanged, baled, packed, disassembled or handled, including auto wrecking yards, house

SUB-CHAPTER M. FHO -- FLOOD HAZARD OVERLAY ZONE
SECTION 3.294
GENERAL INFORMATION:
The flood hazard areas of the Umatilla Indian Reservation are subject to periodic inundation which
may result in loss of life and property, health and safety hazards, disruption of commerce and
governmental services, extraordinary public expenditures for flood protection and relief, and
impairment of the tax base, all of which adversely affect the public health, safety, and general welfare.
These flood losses are caused by the cumulative effect of changes in stream morphology, bedload (size,
density, roughness of material), slope and related sinuosity of the stream, and in changes in carrying
capacity of the stream due to the placement of fill material or other development in areas of special
flood hazards, which increase flood heights and velocities, harms habitat critical to protected species,
and when structures and materials are inadequately anchored, damage uses and properties in other
areas. Uses that are placed in harm’s way, inadequately floodproofed, elevated, or otherwise protected
from flood damage also contribute to flood loss.
SECTION 3.295
PURPOSE:
The purpose of the Flood Hazard Overlay Zone (FHOZ) is to promote and protect the public health,
safety and general welfare, to protect soils, water quality, and quantity, to maintain and improve fish
and wildlife habitat and minimize public and private flood losses due to flood, mudflow or flood-related
erosion by provisions designed to:
1.
Restrict or prohibit uses which are dangerous to health, safety, or property in times of flood,
mudslide and flood-related erosion hazards or which cause increased susceptibility to damage
from these events;
2.
Require that uses vulnerable to floods, mudslide and flood-related erosion hazards, including
public facilities which serve such uses, locate or install such facilities as may be necessary for
flood protection at the time of initial construction;
3.
Ensure that potential buyers are notified when property is in a Special Flood Hazard Area;
4.
Minimize the expenditure of public money for costly flood control projects;
5.
Minimize the need for rescue and relief efforts associated with flooding, mudslide and floodrelated erosion hazards and generally undertaken at the expense of the general public;
6.
Minimize interruptions to commerce;
7.
Minimize damage to public facilities and utilities such as water and gas mains, electric,
telephone and sewer lines as well as streets and bridges located in a Special Flood Hazard Area;
8.
Ensure that those who occupy the Special Flood Hazard Areas assume responsibility for their
actions;
9.
Protect Tribal resources;
10.
Preserve natural and beneficial floodplain functions;
11.
Afford citizens and residents of the Umatilla Indian Reservation the opportunity to obtain flood
insurance through the National Flood Insurance Program by ensuring compliance with 44 CFR
60, Requirements for Flood Plain Management Regulations; and
12.
Minimize pain and suffering resulting from flooding and its aftermath.
SECTION 3.300
COMPLIANCE:
A lot may be used and a structure or part of a structure may be constructed, reconstructed, altered,
occupied or used in a FHOZ only as these overlay standards permit or allow (see Chapter 15,
Enforcement Procedures).
