RE: Submittal ID 2025-S-9806, WDFW’s comments for Renton’s Critical Area Ordinance
Amendments
Dear Ms. Kerrihard,
On behalf of the Washington Department of Fish and Wildlife (WDFW), thank you for the
opportunity to comment on Renton’s draft Critical Area Ordinance (CAO) amendments as part
of the current periodic update. Within the State of Washington’s land use decision-making
framework, WDFW is considered a technical advisor for the habitat needs of fish and wildlife
and routinely provides input on the implications of land use decisions.
We provide these comments and recommendations in keeping with our legislative mandate to
preserve, protect, and perpetuate fish and wildlife and their habitats for the benefit of future
generations – a mission we can only accomplish in partnership with local jurisdictions.

Applicability
g. Sites Separated from Critical
Areas, Nonregulated: As
determined by the Administrator,
these regulations may not apply to
development proposed on sites
that are separated from critical
areas by pre-existing, intervening,
and lawfully created structures,
roads, or other substantial existing
improvements. For the purposes
of this Section, the intervening
lots/parcels, roads, or other
substantial improvements shall be
found to:
i. Separate the subject upland
property from the critical area due
to their height or width; and
ii. Substantially pPrevent or impair
the delivery of most all functions
and values from the subject
upland property to the critical
area.
To align this section with the Growth Management
Act (GMA), all critical area functions and values
must be protected (WAC 365-196-830). We
recommend incorporating the adjacent edits in
red to align with state standards.
Additionally, we strongly recommend defining and
incorporating terminology for functionally isolated
critical area buffers. Specific information can be
found in Ecology’s guidance document.
For example, Woodinville outlines:
“If a portion of a riparian management zone is
determined to be functionally isolated and
physically separated from the watercourse due to
existing, legally established public roadways,
railroads or other legally established structures or
paved areas...the director may exclude this area
from a riparian management zone provided:
(i) The area does not provide any of the primary
riparian management zone functions of bank
stability, shade, pollution control, contributions of
detrital nutrients, wildlife habitat corridor
connection, or recruitment of large woody debris;
(ii) To the extent feasible, the remaining areas
within the riparian management zone are restored
or enhanced to achieve a net gain in ecological
functions; and (iii) A critical areas report confirms
the area of the riparian management zone as
being functionally isolated and physically
separated from the watercourse, and WMC
21.51.120(6)(c)(i) is satisfied,” which can be found
in the July 24th, 2025 planning commission packet.
Riparian management zone (RMZ) is used here in
place of stream buffers as recommended by
WDFW’s best available science (BAS).

Discharging stormwater into streams, lakes, or

quality degradation, and impacts to fish and
wildlife, even if covered under stormwater
permits. Even if an NPDES permit applies, site-
level impacts (like discharge directly into a salmon
stream) may still require critical area protections
that stormwater codes alone don’t cover. At a
minimum, we recommend including the need to
seek other permits for these activities even if
exempt within city code, such as WDFW’s

We strongly recommend reviewing this chapter in

Additionally, streams/lakes are typically classified

City of Anacortes’ FWHCA section as an example.

REQUIREMENTS

2(c.) Streams and Lakes: The
applicant shall be required to
conduct a stream or lake study
pursuant to RMC 4-8-120 if a site
contains a water body or buffer
area and changes to buffer
requirements or alterations of the
water body or its associated buffer
are proposed, either
administratively or via a variance
request. A stream or lake study is
also required when the project
area is within three hundred feet
(300’) one hundred feet (100') of a
water body even if the water body
is not located on the subject
property.
We recommend revising this section to require
stream or lake studies within 300 feet rather than
100 feet. A 100-foot threshold does not
adequately capture the ecological processes
streams and lakes depend on, including shading,
water quality, and large woody debris recruitment.
WDFW’s BAS (Riparian Ecosystems Vol. 1)
supports wider riparian management zones, often
up to 250 feet or larger, to ensure alignment with
no net loss standards. Another approach may
include basing the need for a stream or lake study
on a watershed-scale analysis, recognizing that
projects upslope or outside a narrow buffer can
still significantly affect hydrology, water quality,
and habitat functions downstream. For example, a
project at the top of a slope that substantially
increases impervious surfaces could worsen
flooding and runoff for property owners
downslope and degrade stream conditions
hundreds of feet away.

The following critical area buffers

- Streams and Lakes
The widths in this table do not meet WDFW’s BAS
standards for riparian areas. All streams,
independent of fish use, shall have protection
measures that ensure no net loss of ecological
values and functions. WDFW’s current best
available science standards and management
recommendations outline the need to use the Site
Potential Tree Height at 200 years (SPTH200) to
measure riparian management zone (RMZ) widths
(see WDFW’s mapping tool and field delineation
guidance). RMZ terminology should replace
“stream buffer,” as RMZs should be considered a
critical area and not a buffer to a critical area.
To stop pollutants from entering streams, RMZs
must be 100 feet wide and fully vegetated at a
minimum. Meeting RMZ standards is especially
critical in highly developed areas like Renton,
where elevated levels of impervious surface
contribute to increased stormwater runoff and
water quality degradation. The importance of
addressing water quality concerns is
demonstrated by the listing of many water bodies
within the city on Ecology’s 303(d) list, which
outlines a trend of continued degraded biological
integrity over time.
Several urban jurisdictions have already aligned
with WDFW’s recommendations. For example,
7
King County is proposing urban stream regulations
that include 180–200-foot buffers for Type S and F
streams. Woodinville is similarly advancing
amendments aligned with WDFW’s BAS. Shoreline
is proposing a standard 200-foot width for all
stream types. These examples illustrate how urban
jurisdictions are proactively collaborating with
WDFW to incorporate scientifically based
standards.

iii. The City may require
enhancement of native growth
protection areas to improve
functions and values, reduce
erosion or landslide potential, or
to meet another identified
purpose of these critical area
regulations.
A common addition to this section that many
jurisdictions are utilizing includes:
“Standard riparian management zone widths
presume the area is densely vegetated with a
native plant community appropriate for the
ecoregion, consisting of an average of 80% native
cover comprised of trees, shrubs and groundcover
plants. If the existing area is sparsely vegetated or
vegetated with invasive species, the buffer must
either be enhanced through an approved
mitigation plan or increased by 33%.” This ensures
that there is an incentive to enhance degraded
RMZs. Covington (Planning Commission meeting),
Woodinville (planning commission packet), Skagit
County (meeting agenda packet (14.24.530)), and
other jurisdictions all utilize some version of the
above language to incentivize healthy critical area
buffers.

Please review WAC 365-190-130, which outlines
the types of FWHCAs that require specific

we recommend designating the riparian

also recommend designating wildlife habitat
corridors here. WAC 365-196-335 states, “Each
county or city planning under the [growth
management] act must identify open space
corridors within and between urban growth areas.
They must include lands useful for recreation,
wildlife habitat, trails, and connection of critical

STANDARDS:
7. Streams and Lakes: (a).
Classification systems: The
following classification system is
hereby adopted for the purposes
of regulating Streams and Lakes in
the City. This classification system
is based on the State’s Permanent
Water Typing System WAC 222-16-
030. Stream and lake buffer widths
are based on the following rating
system:
WAC 222-16-030 and WAC 222-16-31 are used to
classify streams for Forest Practices under the
Forest Practices Board. These stream
determinations are used for temporary impacts
associated with Forest Practices in forested areas
and are not designed to be used for regulations for
urban or permanent impacts.
WDFW’s BAS finds that all streams are important
for ecosystem services and salmon recovery,
regardless of whether or not they are fish-bearing.
Type Np and Ns streams provide cold water,
sediment regulation, and organic inputs that are
critical to maintaining the physical, chemical, and
biological integrity of downstream fish-bearing
waters. Np and Ns streams often function as
stormwater overflow channels, a role that
becomes especially critical in highly urbanized
areas where extensive impervious land cover
increases flooding risks.
The loss or degradation of Np and Ns streams
through reduced buffer widths or unregulated
disturbance leads to cascading effects on water
quality, which has cascading impacts on fish-
bearing waters downstream and public safety.
For these reasons, we do not recommend utilizing
the Forest Practice stream typing system as a
mechanism to help establish RMZ widths based on
fish use.

D(i)(b) Piped or Culverted Streams:
(1) Building structures over a
natural stream located in an
underground pipe or culvert
except as may be granted by a
variance in RMC 4-9-250 are
prohibited. Transportation or
utility crossings or other
alterations pursuant to subsection
J of this Section are allowed.
Pavement over a pre-existing
piped stream is allowed.
Relocation of the piped stream
system around structures is
allowed...
(2) No buffers are required along
segments of piped or culverted
streams. The City shall require
easements and setbacks from
pipes or culverts consistent with
stormwater requirements in RMC
4-6-030 and the adopted drainage
manual.
If a piped stream segment is not currently covered
by pavement, we recommend prohibiting new
pavement in these areas. The long-term goal
should be to daylight streams where feasible.
Additional paving would only create further
obstacles to achieving that outcome and would
likely result in a net loss of critical area functions
and values.
Additionally, due to age and environmental
factors, piped stream segments will eventually fail
and need to be replaced in compliance with
current fish passage standards, as required by
state law (WAC 220-660-190). With no buffer for
these stream segments, future restoration efforts
and infrastructure maintenance will be difficult to
achieve. Development placed too close to piped
stream segments may perpetuate non-conforming
structures and increase public safety hazards
related to flooding and erosion as storm
intensities increase. A wider buffer for piped
segments would provide better stormwater
management support, water quality protections,
and provide enough space to allow flexibility to
meet state requirements for fish passage and/or
flow capacity of water crossing structures (e.g.,
culverts) when aging infrastructure needs to be
updated.

If buffer averaging is retained, we strongly
recommend adding a provision that no portion of
the buffer may be reduced below 100 feet.
Scientific research compiled in WDFW’s Best
Available Science demonstrates that 100 feet is
the minimum width necessary to provide basic
functions such as pollution filtration. Allowing
buffers narrower than this threshold would
compromise water quality protection and fail to
meet no net loss standards. An additional
provision could specify that buffer averaging may
only occur in portions of the stream buffer that
currently provide no ecological function, such as
paved parking lots. Importantly, areas with even
limited function, such as a blackberry patch,
should not be considered for averaging, as these
types of areas still contribute ecological value.

mitigation sequence is intended to guide all
decisions related to potential impacts on critical
areas and should serve as the overarching
framework for how impacts are addressed.
Importantly, the first step in this sequence is
avoidance, which must be proven to the fullest
extent. Language commonly found to help guide
avoidance includes:
“All feasible and reasonable measures as
determined by the department have been taken
to avoid impacts, including, where applicable;

for RMZs. Fish-bearing streams rely on intact
ecosystem functions and values, such as shading,
large wood recruitment, filtration, and habitat
connectivity, precisely where they occur. These
functions cannot be replicated elsewhere, as
aquatic species depend on them across the
watershed for survival and recovery. Off-site or
mitigation banking may provide some benefits,
but it does not often replace the localized
functions critical to maintaining fish populations
and overall watershed health. Please review WAC
