RECITALS
1.10 P'IHDIKGS
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 camnerce 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
veloci ties, and, when inadequately anchored, damage uses in other
areas. Uses that are inadequately flood proofed, elevated, or
othezwise protected from flood damage also contribute toward the flood
loss. .
1.20 fORPOSES
It is the purpose of this Ordinance to proJlDte the public health, safety ,
arrl general welfare, arrl to minimize public arrl private losses due to flood
conditions in SPecific areas by provisions designed to:
1. Protect human life and health.
2. Minimize expenditure of public money and costly flood control
projects .
3. Minimize the needs 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 facil1 ties and utili ties such as water arrl
gas mains; electrical, telephone, and sewer lines; and streets arrl
bridges located in areas of special flood hazard.
6. Help maintain a stable tax base by providing for the sound use arrl
developnent of areas of special flood hazard so as to minimize future
flood blight areas.
7. Ensure that potential buyers are notified that prOPerty is in an area
of speCial flood hazard.
8. Ensure that those who occupy the areas of SPecial flood hazard assume
responsibility for their actions.

whereas the floodway fringe stores excess flocx:i waters. The floodway is
often defined as that portion of the river channel and flood plain requ.ired
to pass flood flows without a significant increase in flood height. By
blocking flow, structures and other developnents in the floodway could
raise flocx:i heights substantially, causing increased water velocities, thus
increasing damages. Due to the hazard of developing wi thin the floodway,
the following standards shall apply wi thin f loodways in addition to those
found in Section 5.
6.10 CCJk::ì.1K1.Jli"'l'.lON
1. Construction or reconstruction of residential structures is prohibited
wi thin designated floodways, except for ( 1 ) repairs, reconstruction,
or improvements to a structure which do not increase the grourXl floor
area; and (2) repairs, reconstruction, or improvements to a structure,
the cost of which does not exceed 50 percent of the market value of
the structure either, (a) before the repair, reconstruction, or repair
is started, or (b) if the structure has been damaged and is being
restored, before the damage occurred. ~rk done on structures to
compl y wi th exis t 1ng heal th, sani tary , or safety codes or to
structures identified as historic places shall not be included in the
50 percent.
2. New construction, substantial improvements, encroachments, and other
developments are prohibited unless certification by a registered
professional engineer or arch! tect is provided demonstrating that
developnents shall not result in any increase in flocx:i levels during
the occurrence of the base f locx:i discharge.

3. Construction materials and methcxis shall conform to Section 5.104,
"Materials and Methcxis," of this Ordinance. , .
4. On existing lots of record where sufficient lot area is available to
meet county standards, new construction, substantial developnent, or
the placement of utili ties shall occur outside of the floodway.
5. The construction of basements shall not be permitted within the
fl~y. . ~
6. The placement of fill for the purpose of elevating a structure shall
not be permitted wi thin the fl~y.
7. Foundation construction for 'structures within the floodway shall be
designed to allow for the free flow of flood waters.
6.20 SUBDIVISIONS
1. The floodway shall not be considered usable lot area for proposed
subdivisions. Proposed subdivisions must contain sufficient area
outside of the floodway with sui table characteristics to meet county
standards .
2. Floodway areas may be included in the boundaries of a plat as
canmunity property, recreational area, or other similar open space.
3. Camper vehicles occupying recreational vehicle or travel trailer parks
may utilize the floodway areas for temporary use only and shall be
readily removable in the event of a flood.
6.30 STœAGE
1. The storage or processing of materials that, during the time of
flooding, are flanmable, eJ<plosive, or othezwise injurious to human,
animal, or plant life shall not be stored in the floodway.
2. Materials that are buoyant shall not be stored or placed in the
floodway unless secured against roovement during a flood.
6.40 .t'!<Œ.I:!J'dœu USES
Uses that do not obstruct floodways or threaten other land and have a low
flood damage potential shall be preferred wi thin floodways. Examples
include but ,are not limited to agriculture, stock grazing, parks, golf
courses, horticulture, forestry, parking areas, or activities that are
readily removable in the event of floods.

SECTION 7
WETLANDS MANAGEMENT IN FLOOD
HAZARD AREAS
Wetlands are areas of great natural productivity and hyàrologica1 utility,
providing natural flood control, flood desynchronization, and flow
stabilization of rivers and streams. The unrestricted use and developnent
of wetlands may destroy many of these beneficial qualities which directly
affect human health and safety during flood events. The piecaneal
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 wi thin Jefferson County should, to the maximum extent
possible, seek to avoid the short and long tenn adverse impacts associated
wi th the destruction or modification of wetlands, especially those
activities which limit or disrupt the ability of the wetland to ameliorate
flooding impacts.
7.101 WETLANDS MANAGEMENT
1. Proposals for developnents within flood hazard areas shall be revi~
by the Jefferson County Planning and Building Department for impacts
on wetlands located within flood hazard areas.
2. Developnent activities in wetlarXIs 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 WetlarXIs Inventory, the Jefferson County
Flood Insurance Rate Maps, and any subsequent wetland studies shall be
available to the public at the Jefferson Co1mty Planning and Building
Department to aid in identifying wetland areas wi thin flood hazard
areas .

SECTION a
COASTAL HIGH HAZARD AREAS
Coastal high hazard areas, designated on the FIRMs as zones Vl-V30, VE,
and/or V, are located in areas of flood hazard associated with high
veloci ty water fran surges, including but not limited to storm surges and
tsunamis. Therefore, in addition to meeting all provisions in this
Ordinance, the following provisions shall also apply:
1. All new all~ble construction and substantial improvements in zones
VI-V30 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 ccmpments. Wind and water loading values shall
each have a one percent chance of being equalled or exceeded in
art'f given year (lOa-year mean recurrence interval).
c. A registered professional engineer or arch! tect 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 bot tan of the lowest structural member of the lowest
floor (excluding pilings and columns) of all new and substantially
improved structures in Zones Vl-30 and VE and whether or not such
structures contain a basement. The local administrator shall maintain
a record of all such infonnation.
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 wi thcut 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 10 and no more
than 20 pounds per square foot.
21
15 ¡.~';; 00
558
c. Use of breakaway walls which exceed a design-safe loading
resistance of 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 arch1 tect certifies that the
designs proposed meet the following conditions:
1) Breakaway wall collapse shall result from a water load less
than that which would occur during the base flood.
2) 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 canponents (structural and ncnstructural) . Maximum
wind and water loading values to be used in this
determination shall each have a one-percent chance of being
equalled or exceeded in any given year (100-year mean
recurrence interval).
5'. If brealœwa.y walls are utilized, such enclosed space shall be usable
solely for parking of vehicles, building access, or storage. Such
space shall net be used for human habitation.
6. The use of fill for structural' support of buildings shall be
prohibi ted.
7. Man-made alteration of sand dunes which would increase potential flocxi
damage shall be prohibited.

missioners on February 13, 1989, at
2:00 p.m, in the Commissioner's
Chambers of the Jefferson County
Courthouse, 1820 Jefferson Street
Port Townsend, Washington. Th~
purpose of the revisions is to bring
the Jefferson County Flood Plain
Management Ordinance into confor-
mity with Chapter 86. 16 RCW
"Flood Plain Management," and
Chapter 173- 158 WAC "Flood
Plain Management," ,
The document complete with propos-
ed text changes is available at the
Jefferson County Planning and
Building Department, County Court-
house, Port Townsend, Washington

may do so in writing to the jeffer~o;
County Planning and Building
Department (PO Box 1220, Port
Townsend, Washington 98368) or
provide testimony at the public hear-
ing,
The proposal is to revise the follow-
ing sections:
Section 2, "Definitions": Expanded
to include definitions for areas of
shallow fl~oding, breakaway walls,
coastal high hazard areas critical
facilities, and wetlands. Th~ coastal
flood hazard area is deleted.
Section 4, "Administration": A sec-
tion is added that addresses flood
hazard areas which do not have
detailed base flood elevation data, It
states what information shall be re-
quired by the County to ensure that
proposed construction will be suffi-
ciently elevated to be reasonably
free .from_ fl'?O,ding.
SeCtion 5, "Flood Area t'rot~
Provisions": Residential construction
requirements and nonresidential con-
struction requirements are addressed
in separate sections, New restrictions
are added to construction of enclos-
ed areas below the lowest floor of
residential and nonresidential struc-
tures. . Flood proofing of heating,
plumbmg, and other service facilities
would be required. New sections on
critical facilities and shallow flooding
areas are added.
Section 6, "Floodways": New con-
struction and substantial im-
provements to residential structures
in flood ways are prohibited.
Reference is made to construction
materials and methods required by
Section 5.
Section 10, "legal Provisions": The
Jefferson County Prosecuting At-
torney is given authority to ensure
compliance with the provisions of the
Ordinance through the use of civil
penalties. Enforcement procedures
are enumerated.
Two new sections are proposed:
"Wetlands Management in Flood
Hazard Areas": The section refers to
th@.llln.ctions,_that:wetlands perform, ,.
their capacity to mitigate impacts of
flooding, and the adverse effects on
flood area management that result
from altering or destroying wetlands.
The section then proposes review of
development activities in wetlands
that are within flood hazard areas to
ensure that wetlands capacity to
reduce flood hazards is not adverse-
lýimpacted. This section is suggested
by the Department of Ecology. It is
not required.
"Coastal High Hazard Areas": This
is a new section dealing with area
subject to storm¡wCPtes and..tsunamis.-.
It specifies required :elevations and
methods for new construction in these
areas and prohibits the use of fills
and alteration of dunes,
These revisions (with one exception)
are required by WAC 1730158,
Flood Plain Management, in order to
meet the standards of the National
Flood Insurance Program. The op-
tional revision proposed in the
Department of Ecology's model or-
dinance is "Wetlands Management
in Flood Hazard Areas."

revise the following sections:
1. Definitions
2. Administration
3. Flood Area Protection Provisions
4. Floodways
5. Legal Provisions.
In addition, the following twO new sections are proposed: "Wetlands Management
in Flood Hazard Areas, II and IlCoastal High Hazard Areas. II
~
These revisions (with one except1OÏÏ) are required by WAC 173-158, Flood Plain
Management, in order to meet the standards of the National Flood rnsurance
Program. The optional revision proposed in the Department of Ecology's model
ordinance is IlWetlands Management in Flood Hazard Areas. II
Section 2, IIDefini tions" : This section is expanded to include definitions for
areas of shallow flooding, breakaway walls, coastal high hazard areas, critical
facilities, and wetlands. The coastal flood hazard area is deleted.
Section 4, IIAdministrationll: A section is added that addresses flood hazard
areas which do not have detailed base flood elevation data. It states what
information shall be required by the County to ensure that proposed
construction will be sufficiently elevated to be reasonably free fran flooding.

Dear Mr. Pearson:
Thank you for the opportunity to review Jefferson County's
Draft Floodplain Management Ordinance. Based upon my
review, I find the ordinance to be compliant with both stata -
and federal requirements. The effective date of the
ordinance will have to be changed to reflect the new
aùupl.lon däte, though.
Upon final adoption of the ordinance by the County
Commission, please forward a copy to Mr. Joe weber, Federal
Emergency Management Agency, Region x, Federal'Regional
Center, Bothell, WA, 98021-9796.
Thank you for your prompt and thorough attention to the
ordinance amendment process. It I can be of further
assistance, plea~e call me tit (206) 459-6791.
