18.22.600 Purpose.
The purpose of this article is to:
(1) Protect, restore, and maintain native fish and wildlife populations by protecting and conserving
fish and wildlife habitat and protecting the ecological processes, functions and values, and
biodiversity that sustain these resources.
(2) Protect valuable aquatic and terrestrial habitats, including lakes, ponds, rivers, and streams and
their associated riparian areas, corridors for Washington State Department of Fish and Wildlife
(WDFW) Priority Species, state or federally listed species and the ecosystem processes on which
these areas depend.
(3) Regulate development so that isolated populations of species are not created and habitat
degradation and fragmentation are minimized.
(4) Maintain the natural geographic distribution, connectivity, and quality of fish and wildlife
habitat and ensure no net loss of ecological functions and values of such important habitats,
including net losses through cumulative impacts. [Ord. 5-20 § 2 (Appx. A)]
18.22.610 Classification and designation.
FWHCAs are areas that serve a critical role in sustaining needed habitats and species for the
functional integrity of the ecosystem, and which, if altered, may reduce the likelihood that the
species will persist over the long term. FWHCAs may include, but are not limited to, rare or
vulnerable ecological systems, communities, habitat or habitat elements including seasonal ranges,
breeding habitat, winter range, and movement corridors; and, areas with high relative population
density or species richness. FWHCAs does not include such artificial features or structures as
irrigation delivery systems, irrigation infrastructure, irrigation canals, or drainage ditches that lie
within the boundaries of, and are maintained by, a port district or an irrigation district or
companyirrigation districts.
(1) The following are designated as FWHCAs:
(a) Areas where federally listed species (endangered and threatened) and state-listed species
(endangered, threatened, and sensitive species) have a primary association. This may also
include candidate species as listed on WDFW Priority Habitats and Species (PHS) program;
(b) Rivers and streams not otherwise addressed under Washington State Forest Practices
regulations (chapter 76.09 RCW and title 222 WAC);
(c) Commercial and recreational shellfish areas;
(d) Kelp and eelgrass beds;
(e) Surf smelt, Pacific herring, and Pacific sand lance, and other forage fish spawning areas;

18.22.630 Protection standards.
(1) General. An application for development, land disturbing activity, or use land disturbance,
development or use on a parcel of real property containing a designated FWHCA or its associated
buffer shall adhere to the all of the requirements set forth below.
(2) Types of special reports for FWHCA. When a development, land disturbing activity or use, or
activity is proposed on lands which may contain a FWHCA or its associated buffer, an on-site
habitat evaluation may be required to determine if a FWHCA or its associated buffers occur in the
project area. When required by this section, an applicant shall submit a report documenting the
results of an on-site habitat evaluation conducted by a qualified professional or wildlife biologist
pursuant to the special report requirements found in Article IX (Special Reports) of this chapter
for review and approval by the countyDCD. Based on the results of the on-site evaluation, a special
report shall be prepared by a qualified professional or wildlife biologist and shall be one of the
following:
(a) Habitat reconnaissance letter. This type of report shall be used if the field evaluation
determines that no regulated FWHCA or buffer is present in the proposed project area, which
includes those areas that may be temporarily or permanently affected by construction-related
activities or would be within the limits of clearing for construction. Habitat reconnaissance
letters shall be prepared by a qualified professional or wildlife biologist based on requirements
presented in Article IX (Special Reports) of this chapter;
(b) Habitat management plan. This type of report shall be used if the field evaluation
determines that any portion of the development occurs within a regulated FWHCA or buffer,
which includes those areas that may be temporarily or permanently affected by construction-
related activities or would be within the limits of clearing for construction. Habitat
management plans shall be prepared by a wildlife biologist based on report requirements in
Article IX (Special Reports) of this chapter;
(c) Enhancement Plan. An enhancement plan of degraded FWHCA or its associated buffer
may be prepared by a qualified individual professional, agency, or wildlife biologist. The plan
shall be reviewed and approved by DCD;
(d) Dive survey. If the proposed use, development, or activity occurs in marine water, a dive
survey shall be required to determine if any FWHCA is present in the project area and if any
FWHCA has the potential to be affected by the proposal. The results of the survey shall be
described in a special report and supported by photos taken underwater; or
(e) Use of best available information. If the potential FWHCA is located off of the property
involved and is inaccessible, the best available information shall be used to determine the
FWHCA boundary and any buffer.
(3) Vegetation retention required within a FWHCA or its buffer. Compliance with all of the
following regarding vegetation retention is required:
(a) Vegetation within a FHWCA or its associated buffer shall be retained to the extent
practicable. Unless exempt under this chapter, vegetation removal or alteration of a FWHCA
or an associated buffer shall be approved by DCD;

DCD will ensure that they are adequate. Change made
Commented [GB12]: Steve Mader 12/14/25
(b) Altering the habitat conditions (existing functions and values) of a FWHCA or its
associated buffers without prior approval by DCD is prohibited;
(c) All trees and understory vegetation lying outside of road rights-of-way and utility
easements shall be retained (except for hazard trees) during maintenance clearing of rights-of-
way for roadways and utilities; provided, understory vegetation damaged during approved
clearing operations may be pruned; and
(d) Damage to FWHCA and their associated buffers from land disturbing activity vegetation
retained during initial clearing activities shall be minimized by installing temporary
construction fencing before grading near the buffers, and the falling of trees away from the
these areasdirectional felling of trees to avoid critical areas and vegetation to be retained.
(4) Buffer marking. To ensure that buffers are not impacted by adjacent new development or new
land disturbing activity and to provide notice of the location of buffers, DCD may require any of
the following:
(a) Showing the location of the critical area and buffer on all approved site plans adjacent to
development or land disturbing activity;
(b) Adding permanent fencing, berms, barriers, or native vegetation plantings. This is intended
to ensure that development or land disturbing activity does not encroach upon buffers;
(c) Posting signs along the buffer edge adjacent to the development or land disturbing activity
for commercial, industrial development or uses, or for development or uses on public lands.
This is intended to ensure that the public knows the location of the buffers.
(d) Record a notice to title on the property with the Jefferson County Auditor prior to approval
of the application, if the location of the critical area or its associated buffer FWHCA is not
identified in the development application or on the County’s GIS mapping system. This is
intended to disclose to future buyers the existence of critical areas and their associated buffers.
(5) Buffers – standard requirements. The administrator shall have the authority to require buffers
from the edges of all FWHCAs in accordance with this chapter based on all of the following
requirements:
(a) General buffers.
(i) Buffers shall be established for activities adjacent to FWHCAs as necessary to protect
the integrity, functions, and values of the resource, consistent with the requirements in
Tables 18.22.630(1) and 18.22.630(2) of this section.
(ii) A building setback line of five feet is required from the edge of any buffer area;
however, nonstructural improvements such as septic drain fields may be located within
setback areas.
(iii) Buffers shall be retained in their natural condition; however, minor pruning of
vegetation (as outline is Section 18.22.230(3)(q) JCC) to enhance views or provide access
may be permitted as long as the function and character of the buffer are not diminished.

a given year. Addressed in Section 18.22.230(3)(q)
(iv) Lighting shall be directed away from the FWHCA.
(b) Standard buffers for FWHCAs.
(i) The standard buffer widths required by this article are considered to be the minimum
required to protect the FWHCA functions and values at the time of the proposed activity.
When a buffer lacks adequate vegetation to protect critical area functions, the
administrator may require additional documentation before allowing a proposal for buffer
reduction or buffer averaging.
(ii) The standard buffer shall be measured landward horizontally from the ordinary high-
water mark (OHWM),channel migration zone (CMZ), or from the outer edge of the
FWHCA as identified in the field. The following standard buffer width requirements are
established for streams; provided, portions of streams that flow underground may be
exempt from these buffer standards at the administrator’s discretion when it can be
demonstrated that no adverse effects on aquatic species will occur.

(6) When buffer averaging may be allowed.
(a) The administrator shall have the authority to average buffers widths adjacent to in a
FWHCA area up to 25 percent when all of the following criteria are met:
(i) The specific standards for mitigation sequencing in JCC 18.22.640 have been applied
during the siting and design of the proposed project. To the extent practicable, that may
include consideration all of the following avoidance and minimization measures:
(A) Trees and other existing native vegetation are avoided, and
alterationsdevelopment, land disturbing activities, and uses are placed on existing
road grades, utility corridors, or other developed lands if present; or
(B)The buffer is increased adjacent to the higher-functioning area or more-sensitive
portion of the buffer or FWHCA and decreased adjacent to the lower functioning
or less-sensitive portion; and
(ii) Lower intensity land uses are located in the reduced buffer area if feasible;
(iii) The development is designed to separate and screen impacts such as noise, glare,
and vegetation trampling, etc. of adjacent land uses from the critical area. The site
design shall consider the varying degrees of impacts of different land uses. For
example, parking lots, store entrances, and roads generally have higher noise and glare
impacts than the rear of the store. Site screening should take advantage of natural
topography or existing vegetation, wherever possible. Where natural screening is not
available, berms, landscaping, and structural screens should be implemented (e.g.,
orient buildings to screen parking lots and store entrances from critical area).
Landscaping shall be consistent with JCC 18.30.130; and
(iiiv) The total area contained in the buffer after averaging is no less than that which would
be contained within the standard buffer area and all increases in buffer dimension are
parallel to the FWHCA;
(iiiv) The buffer averaging does not reduce the functions or values of the FWHCA or
riparian habitat, or the buffer averaging, in conjunction with vegetation enhancement,
increases the habitat function;
(ivvi) The buffer averaging is necessary due to site constraints caused by existing physical
characteristics such as slope, soils, vegetation, or existing legally permitted development;
(vii) The slopes adjacent to the FWHCA within the buffer area are stable;
(viii) Buffer averaging of reduced buffers shall not be allowed; and
(viiix) The modified buffer shall meet the well vegetated buffer standard, which is
comprised of at least 40 percent aerial cover of native trees and shrubs in its existing or
proposed enhanced condition at maturity. This shall also include the removal of invasive
non-native plants (e.g., Himalayan blackberry) or noxious weeds and replacement with
native vegetation. An enhancement plan or habitat management plan shall be required to

standards are met.
(b) The administrator shall have the authority to average buffer widths adjacent to in a
FWHCA area up to 50 percent when all of the following requirements are met:
(i) A habitat management plan shall be submitted;
(ii) The modified buffer shall meet the definition of a fully vegetated buffer, which shall
contain at least 80 percent aerial cover of native trees and shrubs in its existing or proposed
enhanced condition at maturity. This shall also include the removal of invasive non-native
plants (e.g., Himalayan blackberry) or noxious weeds and replacement with native
vegetation. An enhancement plan or habitat management plan shall be required to achieve
this standard. Thisese plans shall include a 5-year monitoring plan to ensure that standards
are met;
(iii) Allows for the natural movement of a stream within its floodplain or channel migration
zone;
(iv) Separates development from potential flooding impacts taking climate resilience
measures into consideration;
(v) Limits visual, auditory, and direct intrusion between critical areas and developed
environments;
(vi) The buffer averaging does not reduce the functions or values of the FWHCA or riparian
habitat andPprotects important wildlife habitat components for species dependent on or
associated with wetland, marine, and riverine environments;
(vii) Protects wildlife movement corridors; and
(viii) Does not significantly impact erosion and landslide hazard areas adjacent to the
critical area.
(7) When buffer reduction may be allowed.
The administrator has the authority to reduce standard buffer widths outlined in Table 18.22.630(1)
and Table 18.22.630(2) at the location of a proposed development on a case-by-case basis up to
25 percent. The decision to reduce standard buffer widths of up to 25 percent shall be processed
as a Type I land use decision under JCC 18.40.040.

Applicants for a reduced buffer shall demonstrate in a habitat management plan to the satisfaction
of the administrator that all of the following criteria are met:
(a) Buffer averaging is not feasible;
(b) The specific standards for mitigation sequencing in JCC 18.22.640 have been applied
during the siting and design of the proposed development, which may include consideration
of all or the following avoidance and minimization measures:
(i) Trees and other existing native vegetation are avoided, and alterations are placed on
existing road grades, utility corridors, or other developed lands if present;
(ii) The buffer is reduced adjacent to the lower functioning or less-sensitive portion of
the buffer or FWHCA;
(iii) Lower intensity land uses are located in the reduced buffer area if feasible;
(iv) The development is designed to separate and screen impacts such as noise, glare,
vegetation trampling, etc. of adjacent land uses from the critical area. The site design
shall consider the varying degrees of impacts of different land uses. For example,
parking lots, store entrances, and roads generally have higher noise and glare impacts
than the rear of the store. Site screening should take advantage of natural topography
or existing vegetation, wherever possible. Where natural screening is not available,

(c) The buffer reduction shall not adversely affect the habitat functions and values of the
adjacent FWHCA or other critical area;
(d) The buffer shall not be reduced to less than 75 percent of the standard buffer;
(e) The slopes adjacent to the FWHCA within the buffer area are stable;
(f) The reduced buffer shall be fully vegetated. A fully vegetated buffer is one that contains or
will mature into a dense, multi-storied, diverse native vegetation community that provides
riparian functions adequate to protect the adjacent waterbody. A fully vegetated buffer
contains at least 80 percent aerial cover of trees and shrubs in its existing or proposed enhanced
condition at maturity. This shall also include the removal of invasive non-native plants (e.g.
Himalayan blackberry) or noxious weeds and replacement with native vegetation. Based on
the condition of the buffer the administrator may require an enhancement plan or habitat
management plan to achieve the fully vegetated standard in its existing or proposed enhanced
condition at maturity. These plans shall include a 5-year monitoring plan to ensure that
standards are met; and
(g) For overwater development or uses, a reduction of the buffers shall be based on the review
of reports, established criteria or through consultation with federal and state agencies.

2. Buffer reduction not allowed if buffer averaging is feasible.
(9) Increasing Buffer Widths. Buffer widths may be increased on a case-by-case basis, as
determined by the administrator, to protect the functions and values of a FWHCA. Supporting
documents that may be used to support this determination include but are not limited to:
(a) The FWHCA is used by, or has habitat features that could be used by, state or federally
listed threatened or endangered species;
Formatted: Font color: Accent 6
(b) The FWHCA serves as nesting or foraging habitat for raptors or great blue herons;
(c) The area adjacent to the FWHCA is susceptible to erosion or landslide; or
(d) The area adjacent to the FWHCA has minimal deep rooting, native vegetation or the slopes
are greater than 30 percent.
(10) Voluntary Restoration. FWHCAs and their associated buffers that have been previously
altered such that the functions, values, and natural processes have been diminished are encouraged
to be restored to conditions that existed historically or prior to the alteration.
Voluntary restoration requires the submission of an enhancement plan or habitat management plan
to DCD for review and approval prior to issuance of a County permit to restore a FWHCA or its
associated buffer.
DCD shall provide information or technical expertise, where possible, in facilitating restoration of
a FWHCA or its associated buffer to previously existing conditions. This could include, but is not
limited to, referring interested property owners to restoration information, efforts, and funds.
(11) Stream Crossings. Stream crossing may be permitted within FWHCA or their associated
buffers only when no practicable or reasonable alternative location is available. Any private or
public road expansion or construction which is proposed and shall cross streams classified within
this article shall comply with all of the following minimum development standards:
(a) There are no practicable or reasonable alternative location is available;
(b) A habitat management plan and site plan shall be submitted that show how the impacts
to the FWHCA and its buffer are minimized, that any disturbed areas shall be immediately
restored, and the enhanced withthat restoration shall be through the establishment of native
vegetation;
(c) The design of stream crossings shall meet the requirements of the Washington State
Department of Fish and Wildlife Water Crossing Design Guidelines, as amended. Fish
passage shall be provided restored if necessary to address manmade obstructions on site.
Other alternatives may be allowed upon a showing that, for the site under review, the
alternatives would be less disruptive to the habitat or that the necessary building
foundations were not feasible;
(d) Crossings shall not occur in salmonid spawning areas unless no other reasonable
crossing site exists;
(e) Bridge piers or abutments may be allowed either within the floodway or between the
ordinary high water marks, provided no other reasonable alternative placement exists;
(f)Crossings shall serve multiple properties whenever possible; and,
(g) Where there is no reasonable alternative to providing a culvert, the culvert shall be the
minimum length necessary to accommodate the permitted activity.

(12) Utilities. Utilities including sewer lines, on-site sewage systems and stormwater facilities
(serving one parcel, development or legal lot of record) may be permitted in critical area buffers
only when no practicable or reasonable alternative location is available.
Placement of utilities within FWHCA may be allowed pursuant to all of the following
requirements:
(a) A habitat management plan or enhancement plan and site plan shall be submitted that
show the impacts to the FWHCA and its buffer are minimized, that any disturbed areas
shall be immediately restored, and the enhanced with restoration of the site through the
establishment of native vegetation;
(b) Construction of utilities may be permitted in FWHCAs when no practicable or
reasonable alternative location is available and the utility corridor does not cause or
increase habitat fragmentation for state or federally listed species and meets the
requirements for installation, replacement of vegetation and maintenance outlined below.
Utilities are encouraged to follow existing or permitted roads where possible;
(c) Construction of sewer lines or on-site sewage systems may be permitted in FWHCA
buffers when it can be demonstrated that it is necessary to meet state or local health code
requirements, that there are no other practicable alternatives available, and construction
meets the requirements of this article. Joint use of the sewer utility corridor by other utilities
may be allowed;
(d) New utility corridors shall not be allowed in FWHCAs with known locations of federal-
or state-listed endangered, threatened, or sensitive species, except in those circumstances
where an approved habitat management plan is in place;
(e) In addition to meeting the utilities standards a above, new utility corridors (serving more
than one property) proposed within fish and wildlife habitat conservation areasFWHCA or
their associated buffers shall require a critical area variance under JCC18.22.250;
(f) Utility corridor construction and maintenance shall protect the environment of
FWHCAs as follows:
(i) New utility corridors shall be aligned when possible, to avoid cutting trees greater
than 12 inches in diameter at breast height (four and one-half feet) measured on the
uphill side; and,
(ii) New utility corridors shall be revegetated with appropriate native vegetation at not

(a) A habitat management plan or enhancement plan shall be submitted with a site plan
addressing the impacts to the FWHCA and its buffer are minimized, that any disturbed
areas shall be immediately restored, and the enhancedthat restoration shall be with through
the establishment of native vegetation;(b) Trails and other facilities shall, to the extent
feasible, shall be placed on existing road grades, utility corridors, or other previously
disturbed areas;
(c) Trails and other facilities shall be planned to minimize removal of trees, shrubs, snags,
and important wildlife habitat;
(d) Viewing platforms, interpretive centers, benches, and access to them, shall be designed
and located to minimize impacts to wildlife, fish, and/or their habitat;
(e) Private trails, serving one parcel or legal lot of record, may be permitted within the
buffer provided that they do not exceed three feet in width and are designed to minimize
the impact to wetlandsFWHCA and their associated buffers. Trails serving multiple parcels
or subdivision shall not exceed six 6 feet in width in the buffer. Trails shall be constructed
with pervious surfaces or boardwalks and shall not be utilized by motorized vehicles;
(f) The size, configuration and surfacing of regional and public trails within a buffer shall
be determined through a Type II Variance. Regional trails shall be limited to a maximum
of 12-foot-wide paved surface and with a total width of 6-foot-wide gravel shoulders for
non-motorized public access. This shall also include the submission of a mitigation plan
prepared by wetlands specialist qualified professional addressing the impacts to the
FWHCA and its buffer are minimized, so that any disturbed areas shall be immediately
restored, and the enhanced with that restoration shall be through the establishment of native
vegetation.
(17) Stream Relocation.
(i) In addition to the submission of a habitat management plan, the relocation of streams,
or portions of streams requires a variance under JCC18.22.250.
(ii) Relocation of a stream may be allowed when there is no other feasible alternative and
when the relocation will result in equal or better habitat and water quality and quantity, and
will not diminish the flow capacity of the stream or other natural stream processes;
provided, the relocation meets state hydraulic project approval requirements, the relocation
will not impact the based flood elevation of existing development areas (outside of the
project area) within the frequently flooded area, and that relocation of shoreline streams
shall be prohibited unless the relocation has been identified formally by the Washington
State Department of Fish and Wildlife as essential for fish and wildlife habitat enhancement
or identified in watershed planning documents prepared and adopted pursuant to chapter
90.82 RCW. [Ord. 5-20 § 2 (Appx. A)]
18.22.640 Impact Assessment and Mitigation.
The overall goal of mitigation shall be no net loss of ecological functions or values, and no
degradation of natural processes, value, and area within a FWHCA or its associated buffer.
All unavoidable impacts to FWHCA require mitigation.

(1) FWHCA Mitigation Sequence. Mitigation includes avoiding, minimizing, or compensating for
adverse impacts to an FWHCA or its associated buffers. When a proposed use or development
activity development, land disturbing activity, or use poses potentially significant adverse impacts
to a FWHCA or its associated buffer, the preferred sequence of mitigation as defined below shall
be followed unless the applicant demonstrates that an overriding public benefit would warrant an
exception to this preferred sequence.
(a) Avoiding the impact altogether by not taking a certain action or parts of an action;
(b) Minimizing adverse impacts by limiting the degree or magnitude of the action and its
implementation;
(c) Rectifying the adverse impact by repairing, rehabilitating, or restoring the affected
environment to the historical condition or the condition existing at the time of the initiation of
a project;
(d) Reducing or eliminating the adverse impact over time by preservation and maintenance
operation during the life of the actionPreserving or maintaining FWHCA to reduce or
eliminate adverse impacts over time;
(e) Compensating for the adverse impact by replacing, enhancing, or providing substitute
resources or environments;
(f) Monitoring the required rectification, preservation, maintenance or compensation, and
taking appropriate corrective measures when necessary.
(2) Impact Assessment. All potential impacts to a FWHCA and its associated buffer shall be
identified and described in the habitat management plan. Impact assessments shall be made based
on requirements in Article IX (Special Reports).
(3) Mitigation – Minimum Requirements and Types of Mitigation.
(a) Minimum mitigation requirements are as follows:
(i) Unavoidable impacts to a FWHCA area or buffer shall be mitigated with at least a 1:1
mitigation ratio. The administrator has the authority to require buffer mitigation at a higher
ratio if the area to be adversely affected consists of intact native habitat or the risk of
failure is judged unacceptable.
(ii) Unavoidable impacts to a FWHCA shall require mitigation that fully compensates for
all adverse effects to FWHCA functions and values, natural processes, and area.
(b) A FWHCA mitigation shall includeaddress the following options:
(i) On-Site Mitigation. The applicant may propose on-site mitigation if the mitigation
proposal compensates for the loss of functions and valuesor degradation to existing
habitat.
(ii) Off-Site Mitigation. The applicant may propose off-site mitigation if:

(A) On-site mitigation is not feasible and the mitigation proposal compensates for the
loss or degradation of existing habitats and species of functions and values; or
(B) Off-site mitigation occurs within the same watershed or a connected habitat of a
similar nature to the maximum extent practicable and provides equal or better
protection of the FWHCA and compensates for the loss of functions and valuesor a
significant ecological and functional improvement to the FWHCA; and
(C) There is a willing owner that accepts the proposed mitigation; and
(D) A mitigation agreement or easement is recorded that specifies the individuals or
parties responsible for implementing, maintaining, and monitoring the mitigation area.
(c) In-Lieu Fee Mitigation (ILF). As an alternative to permittee-responsible mitigation, an in-
lieu fee program may be used to compensate for impacts or alterations to a FWHCA or a
buffer, if an established in-lieu fee program is available for the project area. Use of the in-lieu
fee program to address impacts to an FWHCA or buffers shall adhere to the in-lieu mitigation
requirements in JCC 18.22.740(4). [Ord. 5-20 § 2 (Appx. A)
