SECTION 1: RECITALS
1.10 FINDINGS
1.
The flood hazard areas of Jefferson County are subject to periodic inundation that
results 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.
2.
These flood losses are caused by the cumulative effect of obstructions in areas of
special flood hazards that increase flood heights and velocities, and, when
inadequately anchored, damage uses in other areas. Uses that are inadequately
flood-proofed, elevated, or otherwise protected from flood damage also contribute
toward the flood loss.
1.20 PURPOSES
It is the purpose of this Ordinance to promote the public health, safety, and general
welfare, and to minimize public and private losses due to flood conditions in specific areas
by provisions designed to:
1. Protect human life and health.
2.
6.
7.
8.
Minimize expenditure of public money and costly flood control projects.
3.
Minimize the need for rescue and relief efforts associated with flooding and generally
undertaken at the expense of the general public.
4.
Minimize prolonged business interruptions.
5.
Minimize damage to public facilities and utilities such as water and gas mains;
electrical, telephone, and sewer lines; and streets and bridges located in areas of
special flood hazard.
Help maintain a stable tax base by providing for the sound use and development of
areas of special flood hazard so as to minimize future flood blight areas.
Ensure that potential buyers are notified that property is in an area of special flood
hazard.
Ensure that those who occupy the areas of special flood hazard assume

responsibility for their actions.
1030 METHODS
In order to accomplish its purposes, this ordinances includes methods and provisions for:
1. Restricting or prohibiting uses which are dangerous to health, safety, and property
due to water or erosion hazards, or which result in damaging increases in erosion or
in flood height or velocities.
2.
Requiring that uses vulnerable to floods, including facilities which serve such uses,
be protected against flood damage at the time of initial construction;
3.
Controlling the alteration of natural flood plains, stream channels, and natural
protective barriers, which help accommodate or channel flood waters;
4.
Controlling filling, grading, and other development which may increase flood damage;
and,
5.
Preventing or regulating the construction of flood barriers which will unnaturally divert
flood water or may increase flood hazards in other areas.

the cost of which equals or exceeds fifty (50) percent of the market value of the
structure either: (A) Before the improvement is started; or (B) If the structure has
been damaged and is being restored before the damage occurred. For the purposes
of this definition, substantial improvement is considered to occur when the first
alteration of any wall, ceiling, floor, or other structural part of the building
commences, whether or not that alteration affects the external dimensions of the
structure. The term does not, however, include any project for improvement of a
structure to comply with existing state or local health, sanitary, or safety code
specifications that are solely necessary to assure safe living conditions or any

SECTION 3: SCOPE
3010 FLOOD HAZARD AREAS
Flood hazard areas, including the coastal flood hazard areas, are identified by the Federal
Insurance Administration in a scientific and engineering report entitled, "The Flood
Insurance Study for Jefferson County, Washington, Unincorporated Areas," dated January
19, 1982, and subsequent amendments, with accompanying flood insurance rate maps,
and are hereby adopted by reference and declared to be part of this Ordinance. These
documents are on file at the Jefferson County Permit Center, 621 Sheridan St., Port
Townsend, WA.
In the event there is a discrepancy between flood insurance rate maps and other
information, or where detailed base information is not provided by the flood insurance rate
maps, verification of flood hazard area information and boundaries may be obtained
following the procedure s established in Sections 4.101.4 of this Ordinance.
3.20 CONSISTENCY
All developments in the flood plain should be consistent with the Jefferson County
Comprehensive Plan, and subsequent amendments, and other applicable plans, policies,
ordinances, regulations, and restrictions, including the Jefferson-Port Townsend
Shoreline Management Master Program, and subsequent amendments, and any
easements, covenants, or deed restrictions where applicable. If any portion of this
Ordinance is inconsistent with any applicable plans, policies, ordinances, regulations, or
restrictions, the stricter shall apply.
3030 LIABILITY DISCLAIMER
The degree of flood protection required by this Ordinance is considered reasonable for
regulatory purposes and is based on scientific and engineering considerations. Larger
floods can and will occur on rare occasions. Flood heights may be increased by man-made
or natural cause. This Ordinance does not imply that land outside the areas of special
flood hazards or uses permitted within such areas will be free from flooding or flood
damages. This Ordinance shall not create liability on the part of Jefferson County, or any
officer or employee thereof, or the Federal Insurance Administration, for any flood
damages that result from reliance on this Ordinance or any administrative decision lawfully
made thereunder.

CHANNEL
Floodways are the portion of the flood plain consisting of the stream channel and
over-bank areas capable of conveying a selected flood discharge and keeping it within
designated heights and velocities. The floodway is intended to carry the deep and fast
moving water. It is the waters within the floodway that most substantially threaten man's
activities and development. It is the floodway that conveys flood waters, whereas the
floodway fringe stores excess flood waters. The floodway is often defined as that portion
of the river channel and flood plain required to pass flood flows without a significant
increase in flood height. 8y blocking flow, structures and other developments in the
floodway could raise flood heights substantially, causing increased water velocities, thus
increasing damages. Due to the hazard of developing within the floodway, the following
standards shall apply within floodways in addition to those found in Section 5 of this
ordinance.
60 10 CONSTRUCTION
1.
Construction or reconstruction of residential structures is prohibited within
designated floodways, except for:
A. repairs, reconstruction, or improvements to a structure which do not increase
the ground floor area; and
8.
repairs, reconstruction, or improvements to a structure, the cost of which
does not exceed 50 percent of the market value of the structure either:

SECTION 7: WETLANDS
Wetlands are areas of great natural productivity and hydrological utility, providing natural
flood control, flood desynchronization, and flow stabilization of rivers and streams. The
unrestricted use and development of wetlands may destroy many of these beneficial
qualities which directly affect human health and safety during flood events. The piecemeal
alteration and destruction of wetlands through draining, dredging, filling, and other means
has an adverse cumulative impact on their ability to reduce flood damages.
Developments within Jefferson County should, to the maximum extent possible, seek to
avoid the short and long term adverse impacts associated with the destruction or
modification of wetlands, especially those activities which limit or disrupt the ability of the
wetland to ameliorate flooding impacts.
70101 Wetlands Management
1. Proposals for developments within flood hazard areas shall be reviewed by the
Jefferson County Development Review Division for impacts on wetlands located
within flood hazard areas.
2.
Development activities in wetlands which are within flood hazard areas shall not be
permitted if they would adversely affect public health, safety, and welfare by
disrupting the wetlands capacity to reduce flood hazards.
3.
Information from the National Wetlands Inventory, the Jefferson County Flood
Insurance Rate Maps, and any subsequent wetland studies shall be available to the
public at the Jefferson County Development Review Division to aid in identifying
wetland areas within flood hazard areas.

SECTION 8: COASTAL HIGH HAZARD AREAS (V1-V30 & VE Zones)
Coastal high hazard areas, designated on the FIRMs as zones V1-V3D, VE, and/or V, are
located in areas of flood hazard associated with high velocity water from surges, including
but not limited to storm surges and tsunamis. Therefore, in addition to meeting all other
provisions in this Ordinance, the following provisions shall also apply:
1. All new allowable construction and substantial improvements in zones V1-V3D and
VE (V if base flood elevation data is available) shall be elevated on pilings and
columns so that:
A. The bottom of the lowest horizontal structural member of the lowest floor
(excluding the pilings or columns) is elevated one foot or more above the
base flood level.
B.
The pile or column foundation and structure attached thereto is anchored to
resist flotations, collapse, and lateral movement due to the effects of wind
and water loads acting simultaneously on all building components. Wind and
water loading values shall each have a one percent chance of being equaled
or exceeded in any given year (1 DD-year mean recurrence interval).
C.
A registered professional engineer or architect shall develop or review the
structural design, specifications, and plans for the construction and shall
certify that the design and methods of construction to be used are in
accordance with accepted standards of practice for meeting the provisions
of A and B of this Section.
2.
The proponent shall obtain the elevation (in relation to mean sea level) of the
bottom of the lowest structural member of the lowest floor (excluding pilings and
columns) of all new and substantially improved structures in Zones V1-3D and VE
and whether or not such structures contain a basement. The local administrator
shall maintain a record of all such information.
3.
All new construction shall be located landward of the reach of mean high tide.
4.
A.
All new construction and substantial improvements shall have the space
below the lowest floor either free of obstruction, or constructed with
nonsupporting breakaway walls, open wood lattice-work, or insect screening
intended to collapse under wind and water loads without causing collapse,
displacement, or other structural damage to the elevated portion of the
building or supporting foundation system.
B.
For the purpose of this section, a breakaway wall shall have a design safe

loading resistance of not less than ten (10) and no more than twenty (20)
pounds per square foot.
Use of breakaway walls which exceed a design-safe loading resistance of
twenty (20) pounds per square foot (either by design or when required by
local or state codes) may be permitted only if a registered professional
engineer or architect certifies that the designs proposed meet the following
conditions:
i. Breakaway wall collapse shall result from a water load less than that
which would occur during the base flood.
ii.
The elevated portion of the building and supporting foundation
system shall not be subject to collapse, displacement, or other
structural damage due to the effects of wind and water loads acting
simultaneously on all building components (structural and
nonstructural). Maximum wind and water loading values to be used
in this determination shall each have a one-percent chance of being
equaled or exceeded in any given year (1 DO-year mean recurrence
interval).
5.
If breakaway walls are utilized, such enclosed space shall be usable solely for
parking of vehicles, building access, or storage. Such space shall not be used for
human habitation.
6.
The use of fill for structural support of buildings shall be prohibited.
7.
Man-made alteration of sand dunes which would increase potential flood damage
shall be prohibited.
