RE: File #08-100260-00-AD; FORWARD GRETTE TECHNICAL MEMORANDUM
McHugh Wetland Verification, 803 South 3481h Street, Federal Way, WA
Dear Mr. McHugh:
This letter forwards comments from the City's wetland consultant on reports prepared in conjunction with
development of your property, and identifies the next steps for proposed development.
Grette Report
Grette Associates, LLC was asked to review the Wetland Verification Reports prepared by John Comis
Associates and the peer -review based Technical Memorandum of Review prepared by Otak, Inc_ for
wetlands and streams on or adjacent to the above -referenced property. Two copies of their January 17,
2008, Technical Memorandum are enclosed.
In their review, Grette summarizes differing points of view between the two reports, and provides a
means to resolve the matter. They have independently assessed the wetland and stream areas adjacent to
the subject property using post corrected GPS coordinates, and identified these areas in Figure I of the
report.
Grette also found that the Comis report does not provide all relevant wetland information required under
Federal Way City Code (FWCC) Section 22-1356 (3) through (7). Grette has listed specific tasks that
your wetland consultant must pursue in order for the report to meet adopted standards.
Lastly, Grette confirmed that wetlands located adjacent to the property are Category I wetlands with 200-
foot buffers. Grette Figure 1 depicts wetlands approximately 145 to 195 feet from the SW comer of your
property. All other wetland areas are more than 200 feet from the site and the major stream area has been
confirmed as 124 feet from the southern property line.
Next Steps
In order to proceed with a development application for this property, the formal land use application must
include a wetland report that addresses the requirements of FWCC Section 22-1356, as well as points
identified in section 5.0 of the Grette report. As discussed at the preapplication conference for Marista's
Coffee, any improvements, including clearing, grading activities that are proposed within any buffer from
the wetland will require Use Process IV review by the Federal Way Hearing Examiner`. However, if all
1 If Process IV review is required, the wetland report must include analysis of applicable intrusion criteria listed in FWCC
Section 22-1359.

TECHNICAL MEMORANDUM
Prepared by: Grette AssociatesLLc January 17, 2008
Prepared for: City of Federal Way File No.: 205.005
Attention: Deb Barker
Re: McHugh Property — Wetland Review
1.0 Introduction
Grette Associates has contracted with The City of Federal Way (City) to assist in the review of
Wetland Verification Reports prepared by John Comis Associates (JCA) dated February 21,
2005 and February 18, 2006 (Reports) for the Joseph Pircey property. In addition, Grette
Associates reviewed a Technical Memorandum of review prepared by Otak (Memo), the City's
former environmental consultant dated September 29, 2006. It should be noted here that the
property has since changed ownership and is now owned by Mr. John McHugh (Applicant). The
property is located at 803 South 348h Street in Federal Way, Washington (Subject Property).
The Subject Property is recorded as King County Tax Parcel 2021049067.
2.0 Review
A Grette Associates biologist conducted a thorough review of the Reports prepared by JCA and
the Memo prepared by Otak. The review focused on verifying the accuracy of the Reports and
Memo for compliance with the requirements of the currently adopted Federal Way City Code
(FWCC) Section 22, Article XIV-Critical Areas. In addition, review goals were to examine the
site in an unbiased manner using the best available science in order to determine the nature of
conflicting findings between the JCA Reports and Otak Memo.
A site assessment was conducted on December 181h, 19'h, and 26 h, 2007. The site assessment
included a verification of the location of previously identified wetlands and regulated streams.
The off -site wetlands and streams were not delineated at the time of our review. Verification of
wetlands was based on the methodology of the Washington State Department of Ecology's
(Ecology) Washington State Wetlands Identification and Delineation Manual, the US Army
Corps of Engineers' Wetlands Delineation Manual, and associated regional guidance letters.
Stream Typing was based on the stream definitions described under WAC 222-16-030 and
FWCC Section 22-1 Definitions. The Subject Property and accessible adjacent areas were also
assessed for additional wetlands not identified in the JCA Reports or Otak Memo. Once
identified, we utilized post -corrected GPS coordinates to determine the closest extent of wetlands
and streams in relation to the Subject Property boundaries. GPS data is provided in Figure 1 at
the end of this memorandum. Wetlands were categorized using currently adopted Federal Way
City Code, Section 22, Article XIV-Critical Areas.

3.0 Summary of Conflicting Findings between JCA and Otak
Otak was contracted by the City to perform a review of the JCA Reports and complete an
inspection of the Subject Property. According to the Memo prepared by Otak, a site inspection
was conducted August 30, 2006. Otak staff conclusions differed from those of JCA regarding
wetland locations, findings of additional wetlands, stream locations and characteristics, and
wetland test pit determinations. These differences in findings are summarized below:
1. Otak disagrees that JCA Test Pit 1 is upland (Otak Test Pit 1);
2. Otak identified one new wetland 150-200 feet SW of JCA Test Pit 2 (Otak Test Pit 6);
3. Otak disagrees that JCA Test Pits 2 and 4 are wetland;
4. Otak disagrees with JCA at what point the drainage ditch south of the property meets the
definition of a stream; and
5. Otak identified an additional drainage or possible stream along the western property line
not identified in the Reports.
In addition to the general assessment of the site, each of these areas was thoroughly examined on
December 18t', 19'', and 26th 2007 by Grette Associates Biologists in order to determine whether
or not each of the above conclusions is accurate. After completing our review of these specific
areas we have come to the following conclusions:
1. We agree with JCA that Test Pit 1 is upland;
2. We agree with Otak that wetland is present at Otak Test Pit 6;
3. We agree with Otak that JCA Test Pits 2 and 4 are upland;
4. We disagree with both JCA and Otak at which point the drainage ditch south of the
property meets the definition of a stream; and
5. We disagree with Otak that a possible stream is present on the western property line.
These conclusions are discussed in detail in the following section.
4.0 Findings — Site Assessment
Wetlands
According to the JCA Reports Test Pit 1 is upland and no wetlands are located on the Subject
Property. We agree with this statement. Our investigation of the area identified as Test Pit 1 in
both the Reports and Memo concluded a preponderance of hydrophytic vegetation, 10YR 2/2
soils at 0-14" and 10YR 3/1 soils with faint mottles at 14-16", and no wetland hydrology or
wetland hydrology indicators present after very heavy rains. As this sample plot only satisfies
one of the criteria for wetland status, this sample plot was determined to be upland.
According to the Otak Memo, a wetland is present approximately 150-200' west of JCA Test Pit
2 (Otak Test Plot 6). We agree with Otak that this area is a wetland. We estimate the size of the
wetland to be approximately 300 square feet. Approximately 60 feet west of this location we
identified an additional wetland area associated with the JCA "western wetland". According to
GPS data, these wetlands are 145 feet and 190 feet from the SW property corner respectively.

151 S. WORTHEN ST. STE. 101 9 WENATCHEE, WA 98801 2111 NORTH 30TH STREET • TACOMA, WA 98403
According to the Otak Memo, JCA Test Pits 2 and 4 are not wetland based on the dominance of
upland vegetation at these locations. We agree with Otak in that these areas have hydric soils,
wetland hydrology, but do not contain a predominance of hydrophytic vegetation and are
therefore upland plots.
Streams
JCA and Otak disagree at which point the drainage south of the Subject Property meets the
definition of a regulated stream. According to FWCC Section 22-1 Definitions:
Stream means "a course or route, formed by nature, including those which have
been modified by humans, and generally consisting of a channel with a bed, banks
or sides throughout substantially all its length, along which surface waters
naturally and normally flow in draining from higher to lower elevations. A stream
need not contain water year-round. In a developing setting, streams may run in
culverts or may be channeled in a concrete, rock or other artificial conveyance
system. This definition is not meant to include irrigation ditches, stormwater
facilities or other artificial watercourses unless they are used by resident or
anadromous salmonid fish, or the feature was constructed to convey natural
streams which existed prior to construction of the watercourse".
During our investigation we observed flowing water, signs of active scour and deposition at a
point 124' south the Subject Property. This point was located using GPS and is shown on Figure
1 at the end of this report. As this is the highest point in the drainage containing both flowing
water and a defined channel, we determined that this is the point at which the drainage becomes
regulated as a stream (Photo 1).

151 S. WORTHEN ST. STE. 101 • WENATCHEE, WA 98801 2111 NORTH 30TH STREET • TACOMA, WA 98403
This stream flows into the West Hylebos wetland complex and subsequently Hylebos Creek, a
salmon bearing stream. It is therefore considered a tributary to Hylebos Creek and is regulated
as a Major Stream. Major Streams require a 100' buffer (FWCC 22-1306). According to FWCC
Section 22-1 Definitions:
Major stream means "any stream, and the tributaries to any stream, which
contains or supports, or under normal circumstances contains or supports, resident
or migratory fish. If there exists a natural permanent blockage on the stream
course which precludes the upstream movement of anadromous salmonid fish,
then that portion of the stream which is downstream of the natural permanent
blockage shall be regulated as a major stream".
The Otak Memo identifies a "ditch-swale-stream system" along the western property boundary
not identified in the JCA Reports. We observed a linear depression along the western property
boundary. After heavy rains, no signs of flowing water, saturated soils, defined channels, or
observations of sediment scour and deposition was observed in this area (Photo 2). This area
therefore does not meet the criteria for a regulated stream or wetland.

5.0 Findings — Report Review
According to FWCC 22-1356 a wetland report shall be prepared by a City approved qualified
professional and contain the following information concerning wetlands identified on or within
200 feet of the Subject Property:
(1) An evaluation of whether the area in question is a regulated wetland, based on
the definition of "regulated wetland" in FWCC 22-1.
(2) An overview of the methodology used to conduct the study.
(3) A description of the wetland and plant communities found therein, a map
delineating the edge of the wetland and location of plant communities, and a
detailed description of the method used to identify the wetland edge.
(4) The wetland classification, according to the U.S. Fish and Wildlife Service
"Classification of Wetlands and Deep Water Habitats in the U.S."
(5) A list of observed plant and wildlife species, using both scientific and
common names, and a description of their relative abundance.
(6) A list of potential plant or animal species based on signs or other observation.
(7) An evaluation and assessment of the existing or potential functions and values
of the wetland based on the following factors: surface water control; wildlife
habitat; pollution and erosion control; groundwater exchange; open space and
recreation; and educational and cultural opportunities.
We find that the JCA Reports accurately describe background information and methods used to
make wetland determinations. However, the JCA Reports fail to provide all the required
information listed in FWCC 22-1356 numbers 3 through 7 above. In addition, although the
"Field Note Sketch Maps" identify general wetland locations and test pits, they do not clearly
show wetland boundaries. In order to meet the FWCC 22-1356 number 3 requirements, JCA
needs to delineate the wetland boundaries within 200 feet of the Subject Property and prepare a
professionally drawn, legible, scaled delineation map, clearly showing property boundaries and
the location, shape and extent of the off -site wetlands, streams, and their associated buffers
within 200' of the Subject Property. Furthermore, JCA will need to prepare an addendum to
their reports that provides the additional information required by numbers 4 through 7 of FWCC
22-1356.

Wetland Rating
The off -site area south of the Subject Property slopes down to the West Hylebos Wetland
Complex. This area contains several slope wetlands that are maintained by subsurface
groundwater moving down slope. The topography of the slope is hummocky and many small
wetlands have formed in shallow depressions created by the hummocks. As such, the off -site
wetlands 145' and 190' SW of the Subject Property form a mosaic with additional off -site
wetlands further down slope that are functionally connected to the West Hylebos Wetland
Complex. The West Hylebos Wetlands are regulated as Category I Wetlands as they contain
more than three Cowardin Classes, one of which is open water. In addition, these wetlands are
considered to be of exceptional local significance and thus Category I. The off -site wetlands
145' and 190' SW of the Subject Property have a functional connection to the West Hylebos
Wetland Complex and are therefore Category I Wetlands and require a 200 foot buffer (FWCC
22-1357).
The review of the Reports, Memo, and site assessment was conducted using the best available
scientific information and methodologies and the best professional judgment of Grette
Associates staff biologists. Final acceptance and approval of Wetland Reports and Delineations
is at the discretion of City staff. If you have any questions regarding this review please contact
me at (253) 573-9300.

Subject: McHugh Site for Marista's Coffee @ Federal Way
John,
I went ahead and did some research and preparation for the meeting with Deb Barker, Senior Planner, at the City of
Federal Way. We prepared 2 map Figures 4 and 5 as supplement data for the JCA reports. They indicate the National
Wetland Inventory (NWI) locations of wetland classes and the USGS topography and drainage features in the area south
and west of the site.
The attached maps show the relationship of the project site to the offsite wetland called "West Hylebos Wetland Complex"
by the Grette biologist. Note that the open water zones (indicated as "PUBW on the NWI map) are more than 1500 feet
south and west of the site. The main stream corridor (for "West Hylebos Creek") extends through the wetland complex
800 feet west of the site. The nearest offsite wetland (designated by our study as "Wetland A") is 145 feet SW of the site
(measured by the Grette biologist). This small Wetland A (at 300 sq. ft. area) is not hydrologically connected to the other
offsite wetlands by surface water or hydric soils. It appears to drain by subsurface flow in a south to southwest direction
based on the overall surface topography for this area. Based on the current version of the 2006 wetland rating manual by
WDOE for a "slope" wetland, the wetland complex (or mosaic) nearest to the site appears to be rated Category III. By the
City's Code definition for wetlands, it appears to be rated a Category 2 wetland and not a Category I as prescribed by the
Grette biologist.
I will present this data to Deb at the City at our meeting Monday morning at 9:00 AM at City Hall. I assume that we are
meeting at the Planning Department.

John Comm -

Subject: Wetland Verification for the Joseph Pirggy Site A Federal Way, located at
803 S. 348th Street, Tax Parcel No. 2021049087, situated in the SW 1/4 of the SE 1/4 of
Section 20-T21N-R4E, W.M., City of Federal Way, King County, Washington
To Whom It May Concern:
John Comis Associates (JCA) has conducted onsite and offsite investigations on February
1, 2005 and again on January 14, 2006, to verify the presence or absence of any regulated
wetlands that may be found within the subject property or on adjacent offsite properties
(see enclosed maps for site specific information including locations and test results).
The original field investigation was done in February 2005 for Architects BCRA (Jeffrey
Brown, Principal) for a reconnaissance study of onsite and adjacent offsite areas within
approximately 100 feet of the property. Then in January 2006, an extended offsite study
was done for the current property owner (Joseph Pircey) to investigate further the offsite
areas within 300 of the property boundary.
The field investigations were limited to a determination of "regulated wetlands" on the
site, or within 300 feet'- of the site boundary. The identification of wetlands was based
on the current 1997 Washin tan Stale Wetlands 1dena ication and Delineation Manual.
This methodology is consistent with methods used by the 1987 Carps of tg'neers
Wetland Delineation Manual. The identification of "regulated wetlands" was also made
The 300-foot distance is the maximum buffer width for the highest rated Class 1 wetland. This represents a
reasonable distance from which a "regulated activity" should not impact a "regulated wetland" (per City of Federal Way
Critical Areas Regulations (definitions, exemptions and buffers).

in accordance with the City o Federal W Critical Areas Re ulation-v. (See Appendix 1
for details on methodology used and standards applied to regulated wetlands in the City).
The extended study includes evaluation for possible offsite wetlands that may be present
in the adjacent areas along the western and southern site boundary as indicated on the
current City of Federal Way Sensitive and Critical Area Inventory Map (see Figure 4).
For the extended offsite study, JCA examined adjacent depressions along measured
transects extending west and southwest from the subject property. These areas were
examined in detail for field indicators including hydrophytic vegetation, hydric soils and
possible saturation within 12 inches of the surface that may occur in the early growing
season.
The scope of work includes review of available map information showing onsite and
offsite conditions within the study area such as the King County "iMAP" information
(Figure 2), the soils survey map (Figure 3) and the City of Federal Way 1998 Sensitive
and Critical Areas Inventory Map (Figure 4).
The "West Hylebos Wetlands Park" and its associated wetland are indicated on the
Sensitive and Critical Areas Map near the southwest corner of this site (see Figure 4).
However, the wetland boundaries are approximate as shown on this map. JCA checked
the adjacent offsite areas within 300 feet using standard wetland delineation methods
along the measured transects and found that all regulated wetlands are mare than 200 feet
from the site. This is indicated on the Field Note Sketch Maps (FNSM) included with
this report (see Figures 5 and 6 for details).
The onsite and offsite work included "routine onsite determination methods" to find any
wetlands that may be exist within or near this site. The FNSM (Figures 5 and 6) and the
sample test plot data (TP 1 thru TP8) show the locations results of the wetland and non -
wetland determinations for the representative test areas (see Appendix 2 for details).
The test plot locations are marked and flagged as indicated on the FNSM. The numbered
points are flagged with blue and green colored ribbons tied to vegetation. The TP's
include holes dug by hand 16-19 inches deep to analyze soils and hydrology conditions
that exist at these representative locations along the measured transects. Vegetation is
used where areas are not significantly disturbed and "typical" conditions are present.
Findings
• The onsite and extended offsite investigations are done during winter wet weather
conditions. The first field investigation (February 2005) was done during normal wet
weather conditions. The second field investigation (January 2006) was done during
very wet weather conditions following periods of much rainfall during the preceding
weeks and rainfall having occurred the previous 24 hours.
• NO onsite or offsite regulated wetlands are found within 220 feet of the subject
property.

■ The "non -wetland" determination within 4 test holes dug in the lower parts of onsite
and adjacent offsite areas is based on a lack of hydrology found in February 2005 (see
FNSM, Figure 5, dated 2/l/05 for locations, and test plot data for TPI, TP2, TP3 and
TP4).
■ TP2 (offsite) @ 67 feet south of the SE property corner and TP4 (offsite) at 50 feet
west of the property are dug in what appears to be the lowest parts of natural
topographic depressions. Both TP2 and TP4 do not have sufficient hydrology
indicators on 2/l/05, but do have saturation at 4" on 1/14/06 after periods of extended
and abnormally heavy rainfall. Both of these depressions are very small (less than
1000 square feet in size) and totally isolated from other offsite wetlands located
farther south and west of the site (see FNSM for other TP locations done in 2006 for
the extended offsite survey).
• Soils in the extended offsite areas to the west and southwest appear to be an "Bverett-
Alderwood" series (EwC), gravelly sandy loam with variable slopes of 6 to 15%. The
Everett-Alderwood series is not listed as a hydric soil on the "Hydric Soils of King
County by the NRCS. However, inclusions of other soil types may occur within a
soil mall unit. See the "Soil Survey Report for Kin County" for details of soil
p Y p g Y
descriptions (excerpts included in Appendix 3).
• The "Seattle Muck" soil type as indicated by the Soils Survey Map (Figure 3) is NOT
found in the extended offsite areas within 250 to 300 feet of the subject property.
• Surrounding upland UP areas are identified extending approximately 220 feet west
and 300 feet southwest as shown by JCA on the FNSM (Figure 5 and 6). The upland
(non -wetland) areas are identified first by dominant non-hydrophytic vegetation
established in the relatively undisturbed forested areas, and appear to have a soil type
that matches the description of an "Everett-Alderwood" series (see field data and soil
descriptions in Appendix 3).
• A regulated offsite wetland area is identified approximately 220 feet west of the
site as shown by JCA on the FNSM (Figure 6).
• A regulated offsite wetland area is identified approximately 300 feet southwest of
the site as shown by JCA on the FNSM (Figure 6).
• A regulated offsite stream corridor is identified approximately 230 feet southwest
of the site as shown by JCA on the FNSM (Figure 6).
Please note that this work did not include a detailed land survey of test plot locations or
property boundaries. Locations as shown on FNSM by JCA are approximate, but based
on accurate hip -chain measurements and hand compass directions made along clearing
lines at the property boundaries. If additional information is requested by the Client or
required for regulatory agency review(s), this can be prepared only after authorization by
the client/applicant. A more accurate map may be prepared by having the delineated
wetland locations surveyed by a licensed land surveyor.

APPENDIX 1
METHODOLOGY FOR WETLAND
DETERMINATION AND DELINEATION
Pircey Property @ Federal Way Wetland Verification
By John Comis Associates
Date 02/18/06
Page 5 of 20
METHODOLOGY
A. APPROACH USED FOR WETLAND DETERMINATION
Wetlands are identified using the Washington State Wetlands Identi ication and Delineation
Manual, prepared by the Washington State Department of Ecology (WDOE), Publication 496-94,
dated March 1997. The 1997 WDOE Wetlands Manual is required to be used by all state
agencies in the application of any state laws and regulations as well as any city or county in the
implementation of any regulations under the Growth Management Act.
The US Army Corps of Engineers, Seattle District has reviewed this manual method and
approved it as a revised version of their Carps of Engineers Wetlands Delineation Manual,
Technical Report Y-87-1, January 1987. The State Manual incorporates the amendments and
clarifications in the 1991 and 1992 documents published by the COE that reflect more current
technical information developed since the original COE Manual was published. It is the intent of
the State Wetlands Manual to result in the identification and delineation of the same areas as
would be identified and delineated under the COE Manual as may be applied for Federal reviews.
The "criteria" which an investigator must use to determine if a test plot is a "wetland" are limited
to the presence of all 3 wetland criteria: hydrophytic vegetation, hydric soils, and wetland
hydrology. This means that to make a positive wetland determination, all 3 criteria must be
positive. The absence of one, two, or all three of the criteria should result in a non -wetland
determination. The presence of dominant "field indicators" is used to determine if a criterion is
met. if a field indicator is absent, then an indirect indicator may be used. For example, the
absence of inundation or saturation during a dry summer field investigation could result in the
hydrology criterion not being met. However, the presence or absence of encrusted detritus on
twigs or blackened leaves on bare ground in a depression may be used to help verify sufficient
inundation during a wetter period of the growing season.
The Manual stipulates 3 key provisions of the definition of wetlands include:
a. Inundated or saturated soil conditions resulting from permanent or periodic inundation
or saturation by ground water or surface water (saturation within 12 inches of the surface for at
least 20 to 30 consecutive days during periods in the Mesic growing season [March thru
October]).
b. A prevalence of vegetation typically adapted for life in saturated soil conditions
(hydrophytic vegetation).
c. The presence of "normal circumstances".
The selection of a specific method and procedure for identifying wetlands may follow one of the
following methods:
■ the "routine determination method" for undisturbed and non -problem area wetlands;
■ the "offsite determination method" for areas within 300' of the site boundary; and/or
• the "disturbed area and problem area wetland determination procedures" for areas with
disturbed or atypical vegetation, soils or hydrology. If an area is disturbed, then a higher
level of analysis such as a "Comprehensive" determination method may be required.
The preferred and simplest method is the "ROUTINE Determination Method" forMica],
generally undisturbed areas with normal environmental conditions. For areas that are complex,
confused, or have disturbed or altered environmental conditions, a "Comprehensive
Determination Method" may be used. This method employs transect sampling procedures in
Pircey Property @ Federal Way Wetland Verification

Date 02/18/06
Page 6 of 20
areas that have been filled or graded where the vegetation, soils or hydrology condition can not be
readily observed.
Generally, the investigator is looking for a portion of the site (called a test plot) where a "typical
condition" exists --where a well established plant community is present with no evidence of recent
clearing, grubbing, filling, grading, or soil drainage activities. This situation should occur during
a period when "normal circumstances" are present. That is during periods of the year when
nonnal environmental conditions such as moderate rainfall and average antecedent moisture
conditions (AMC) exist within a wetland or a watershed area.
For the hydrophytic vegetation criterion to be met, a dominant number (i.e. more than 50%) of
"OBL, FACW and/or FAC" indicator species must be present in the sample plot (see the
discussion of these abbreviations in a later section of this appendix). The vegetation analysis is
based on the 3 dominant species in each of 4 vegetation layers (or strata: trees, saplings/shrubs,
herbs/grasses, and woody vines). Or if only 1 or 2 vegetation layers exist at the test plot, then 5
dominant species are used to make the determination.
If a test plot has no well established vegetation due to recent clearing and grubbing, or the soils
have been severely disturbed due to excavation, filling or grading activities, the test plot is called
an "atypical situation". In atypical or disturbed situations the wetland determination may be
based only on soil borings into the undisturbed soil stratum below the fill line and by hydrology
criteria. if an area is disturbed, then a higher level of analysis such as a "comprehensive"
determination method may be required.
The procedure used for each test plot is indicated on the individual data sheets. The
environmental conditions that exist at the site on the day of the field investigations are indicated
in field notes and marked in the appropriate "normal" (or not nonnal) blank at the top of the data
sheet. if the vegetation, soils or hydrology are found disturbed, this is explained at the bottom of
the sheet. The results for each test plot are recorded on data forms and included with this report
in Appendix 2.
S. KEY DEFINITIONS USED
For this study, "wetlands" are defined using the adopted Slate of W shin eon's Growth
Man menl Act definition:
"Those areas that are inundated or saturated by surface water or ground water at a
frequency and duration sufficient to support, and that under nonnal circumstances do
support, a prevalence of vegetation typically adapted for life in saturated soils conditions.
Wetlands generally include swamps, marshes, bogs, and similar areas." (Corps of
Engineers Regulation 33 CFR 328.3, 1988)
"Wetlands do not include those artificial wetlands intentionally created from non -wetland
sites, including but not limited to, irrigation and drainage ditches, grass -lined swales,
canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape
amenities, or those wetlands created after July 1, 1990, that were unintentionally created
as a result of the construction of a road, street, or highway. Wetlands may include those
artificial wetlands intentionally created from non -wetland areas to mitigate the
conversion of wetlands."

Other key definitions may also apply such as "regulated wetlands" defined by the adopted City of
Federal Way Envirannientalty Sensitive Aregs Ordinance (City Code Article XIV, Div. 7, Section
22-1356 to 1359 for Regulated Wetlands), including codes pertaining specifically to wetland size
and wetland rating referred to in sections of the Federal Way Municipal Code (FWMC).
C. WETLAND DELINEATION CRITERIA
By Vegetation:
For this study, vegetation was primarily used, along with the soils and hydrology criterion, to
delineate the edges of the identified wetland areas. This was due to the general lack of
disturbances within the forested areas of the site. For wetland plant community delineations, we
used vegetation that exists along the wetland margins where plants were well established and
represent typical and normal conditions between hydrophytic and upland conditions.
Plant communities were analyzed in detail and vegetation data were documented on Field Data
Sheets for the individual test plots (TP, or sample plots) shown at locations -on the report figures
and on our field note sketch maps. The onsite analysis test plot data were extrapolated into the
areas shown by JCA as "upland" on the Field Note Sketch Maps (FNSM, see Appendix 2).
For this study, a species is considered dominant in a test plot if more than 10% of the plants
growing in that area appear to be the same species. This is an estimate of the relative density of a
species in a sample area. By routine methods, this is usually made by visual inspection of the
dominant plants in a representative sample area. As defined in the 1997 State Manual, a
dominant species exerts a controlling influence on or defines the character of a plant community.
Dominance on the other hand is used as a descriptor of vegetation that is related to the standing
crop of a species in an area, usually measured by height, aerial cover, or basal area (for trees).
This should not to be confused with a vegetation class that must comprise more than 30% of the
aerial cover in the entire wetland (or upland).
If more than 50% (i.e. 51 or more percent) of the dominant plant species in a test plot are OBL,
FACW and FAC, then the hydrophytic vegetation criteria is said to be met and it is marked "yes"
on the field data form.
The specie identifications are based on available plant keys such as Hitchcock and Cronquist's
Flora o the Pacific Northwesi (1973). To determine whether plant species exhibit hydrophytic
adaptations, if they are native or non-native (introduced), and which strata (tree, shrub, herb) they
normally occupy, we use the National List a Plan! S ecier That Occur in Wetlands: Northwest
(Region 9), published by the US Fish and Wildlife Service, May 1988. The indicator statuses for
the various species found in the area are determined based on the National List together with the
December 1993 supplement for the Northwest Region.
The indicator status describes the estimated probability of a plant species occurring in wetlands.
Indicators are:
OBL = Obligate Wetland species ("almost always occurs", >99% probability)
FACW = Facultative Wetland species ("usually occurs", 67-99% probability)
FAC = Facultative species ("equally likely to occur", 34-66% probability)
FACU = Facultative Upland species ("usually occurs in non -wetlands", 67-99% probability)
UPL = Upland species ("almost always occurs in non -wetlands", >99% probability)
NI = No Indicator assigned (If a species does not occur in wetlands in any region of the National List, then
"no indicator is assigned".)
+ = Slightly more frequently found in wetlands

- = Slightly less frequently found in wetlands
* = Tentative assignment based on either limited information or conflicting reviews from the 1993
Northwest Supplement of the National List.
Parenthesis ( ) around an indicator signifies the status is assigned by JCA, and a question mark (?) after an
indicator signifies it is tentative based on our (JCA) field experience & observations.
By Soils:
For wetland soil determination, we use the hydric soil criterion prescribed in Part III of the
Washington State Manual. Hydric soils are defined as "a soil that formed under conditions of
saturation, flooding, or ponding long enough during the growing season to develop anaerobic
conditions in the upper part. " (USDA-NRCS 1995, Federal Register, 7/13/94, Vol. 59, No. 133,
pp. 35680-83). Note that the definition and criteria for hydric soils may change periodically as a
result of revisions by the National Technical Committee for Hydric Soils (NTCHS). In general,
this occurs in the upper 12" of the soil profile and usually for 20 or more days during the period
when soil temperatures are above biologic zero (410F).
In general, "organic hydric soils" develop as a result of prolonged anaerobic conditions with long
periods of saturation impeding decomposition (peat or muck) and have greater than 16" of
organic matter in the surface layer (Histosols). "Mineral hydric soils" have less than 16" of
organic matter (if some is present, then it may have a'histic epipedon'). They are saturated for
more than 20 consecutive days during tthe_growing season (the period when soil temperatures are
above biologic zero, 41 OF, as defined by "Soil Taxonomy", 1975; usually March -October), and
contain dominant gleying and/or mottling.
The soil color and/or presence of mottling and gleying in a sample are primary field indicators of
whether a mineral soil is either hydric or non-hydric. Non-hydric soils are generally a rusty red
or yellow color. Hydric soils are generally black, gray, or washed out in color. A field indicator
for a saturated organic hydric soil is a rich black matrix color of say 2/1 or 2/2. A field indicator
for a saturated mineral soil is a leached matrix color of say 3/1 or 4/1 or 5/1 or 6/1). A hydric
mineral soil must have a low chroma color feature (at least 1 if not mottled, or a chroma 2 if
prominent mottles are present in the soil matrix).
Gleying and prominent mottling are color indicators of prolonged saturation and indicate that
anaerobic conditions probably exist for sufficient periods of time to develop wetland soils.
Gleyed soils are generally bluish -green to grayish -green in color throughout the soil mass or in
mottles (spots or streaks) interspersed within the dominant soil color (matrix color) in a layer (soil
horizon). Gleying results from the leaching of the dissolved (reduced) iron and manganese
minerals out of the soil matrix. Soils gleyed to the surface or to the surface layer of organic
material are generally considered hydric. Soils that are saturated throughout the year are usually
uniformly gleyed to the surface (Tiner and Veneman 1987).
Mottles are generally yellow to reddish brown blotches or spots accumulating in mineral soil due
to a fluctuating water table during the growing season. The size, number and color of mottles
reflect the duration of soil saturation and thus whether the soil is hydric. Mottling in hydric soils
should be "distinct" or "prominent" in the upper horizon. Mineral soils that have a grayish matrix
(chroma 2 or less) with mottles are hydric if the mottles are not relict mottles. Mineral soils with
a predominantly brown or yellow matrix and light gray mottles are not usually hydric. 2

The National Technical Committee for Hydric Soils has developed criteria for hydric soils and a
list of the Nation's hydric soils (USDA Soil Conservation Service 1987). However, the federal
manual describes certain limitations (page 12-13) for the National and State lists. Therefore, the
SCS maintains a list of hydric soil map units for each county in the US. The list is used for
identifying which soils are hydric by the local soil series description. Soil series descriptions
from the 1973 [MRCS] Soil San ney oLKiLig County is included in Appendix 3.
By Hydrology:
For the wetland hydrology determination, we use the presence of inundation and/or saturation for
a sufficient "hydroperiod" to determine whether hydrology criteria are met. The depth to
freestanding water in a pit or soil probe hole must be less than 12" in wetland margins where
hydric and upland soils and vegetation are transitional. Topographic elevations, encrusted
detritus or debris, silt lines, hydraulic gradients, capillary fringe, or a drainage analysis of offsite
and onsite tributary areas are other means and indicators that may be used to help determine the
presence or absence of sufficient hydrology for a positive wetland determination.
After a wetland determination is made, the wetland area is analyzed to determine if it is a high
quality wetland or if it has any of several irreplaceable ecological functions. The wetland is then
analyzed for any significant habitat values such as size, classifications, plant species diversity,
structural diversity, special habitat features, buffer conditions, and connection to streams or other
habitat areas.
D. WETLAND CLASSIFICATION
Wetlands identified by this study are classified using a hierarchical multi -level approach
developed by the US Fish and Wildlife Service for their scientific classification system. The
classification system is published in the report titled Classiftcation gfWellands a Beep Water
Habitats fihe United States, FWS/OBS-79/31, by Cowardin, et al. (December 1979).
The system of classification divisions is based on habitats that share the influence of similar
hydrology, geomorphology, chemical, or biological factors. The wetland systems involved in the
project site are generally limited to "palustrine" systems. Palustrine wetlands (these are the only
wetlands identified by this study) are divided into classes and subclasses determined by dominant
vegetation such as "emergent" (EM), "scrub -shrub" (SS) and/or'forested' (FO), "aquatic bed'
(AB), and/or "open water" (OW). Water regimes are assigned for each class based on the
hydroperiod or duration of flooding (inundation) or saturation associated with the wetland area.
These are defined for freshwater, non -tidal areas as follows:
WATER REGIME MODIFIERS [NON -TIDAL]
temporarily flooded (A): flooded (inundation by surface water) for brief periods during growing
season but the water table is otherwise well below the soil surface
saturated (13): substrate is saturated for an extended period during growing season but surface
water is seldom present
seasonally flooded (C): flooded for extended periods during the growing season, but usually no
surface water by the end of the growing season
seasonally flooded/well drained (D)
seasonal flooded/saturated (E): flooded for periods, but usually saturated by groundwater at or
near the surface thru most of the growing season
semipermanently flooded (F) flooded throughout growing season in most years, when surface
water is absent, water table is at or near the surface
intermittently exposed (G): flooded throughout year except in years of extreme drought
permanently flooded (H): flooded (water covers land surface) throughout the year in all years

The class of a particular wetland describes its general appearance in terms of either the dominant
vegetation or the substrate. When over 30% cover by vegetation is present, a vegetation class is
used (e.g., "emergent", "scrub -shrub" and/or ':forested'). When less than 30% of the substrate is
covered by vegetation, then a substrate class is used (e.g., "unconsolidated bottom", "aquatic
bed', or "moss -lichen"). Typical demarcations of these classes of palustrine wetland systems are
shown in the Cowardin report. [Also reference is made to the current (1988) National Wetlands
Inventory (NWI) map and legend.]
Wetlands that have a single vegetation species that dominate 90% of the total wetland area are
called a "mono -type". This may occur where more than the one species is present but the total
area of their coverage is less than 10%. If another vegetation class or species dominates more
than 10% of the wetland, then it has higher habitat diversity. This can be based on the number of
plant species found in a class, the number and quality of the structural layers and the interspersion
of classes which creates increased "edge effect" and habitat diversity. This may also result in a
higher wetland "rating".
E. CITY OF FEDERAL WAY WETLAND REGULATION AND RATING
STANDARDS
Wetlands are rated for regulatory purposes using the 3-tiered system specified by the City of
Federal Way Municipal Code for Crilical Areas Regulcnions (FWMC, <<2005). Wetlands may
also be rated using the 4-tiered system published in the Washington State Department of
Ecology's (WDOE) Wetlands Ratin &stem for Western Washin ton (Pub. #04-06-025, August
2004). However, this rating is not used except as a guide in for the wetland analysis and rating as
prescribed by the FWMC criteria and standards.
The standards adopted by the City are applied to areas that are "regulated wetlands". Basically no
regulated activities shall be permitted within a Class I wetland or its buffer. Class II and III
wetlands that are regulated may be allowed to have some alterations if the applicant can
demonstrate either a) no practicable alternative; b) extraordinary hardship; or c) public interest as
defined by the ordinance. For all wetlands types, the applicant must demonstrate all of the
following conditions are met: a) the existence of any plant or wildlife species appearing on the
federal or state endangered or threatened species list will not be jeopardized; b) the proposal will
not lead to significant degradation of groundwater or surface water quality; and c) the proposal

complies with the remaining standards of the chapter, including those pertaining to wetland
compensation and the provision of bonds.
The minimum threshold size for all wetlands is 2,500 square feet. If a wetland is hydrologically
isolated, classified and identified as a Class I,11 or III wetland, and has a total cumulative area of
less than 2,500 square feet, regardless of property lines, then it is exempt from the provisions of
this chapter. Wetlands which are determined to not have exceptional value, and are a Class II
wetland less than 2,500 sq. ft., may be excluded from the provisions of this chapter. Lower
quality Class III wetlands which are determined to be less than 1/4 acre, are severely disturbed, or
are newly emerging wetlands, may also be excluded from the provisions of this chapter.
If a wetland has a large enough area and high enough rating requiring regulation, then appropriate
measures for buffering or impact mitigation shall be required for a new development. Generally,
the minimum threshold size for an "isolated" wetland is 2,500 square feet. An isolated wetland is
one that is not connected directly to another wetland in a system of definite channels or by hydric
soils. This may be defined as "a functional part of an interconnected aquatic system containing 2
or more wetlands contributing to that system".
The size of a wetland shall be measured after a wetland specialist completes the detailed
delineation. The size of smaller areas may be measured by onsite methods such as hip chain or
tape measure by the wetland specialist if the area is clearly less than the threshold size. However,
if the area is close to the threshold size, then a measurement by more detailed methods such as a
land survey may be required to determine the precise size of the wetland for regulatory purposes.
After the wetland boundary is delineated and the size is measured, the wetland is "rated" or
categorized for regulatory purposes. The rating includes the criteria that may be applied to
situations where the boundaries of wetlands may overlap or be contiguous along a stream (i.e.
riparian) corridor or separated by open water bodies or uplands in a patchwork on the landscape.
The rating forms for onsite and offsite wetlands evaluated by this analysis are included with this
report in Appendix 4.

facultative and u land vegetation indicators. This area was tested during very wet site conditions after
significantly heavy rainfall periods in February 2006. The lack of persistent saturation or inundation even at
this time indicates a non -wetland determination along the lower swale area at least 230 feet southwest of the
subject site. Note that the drainage course emerging from the seepage point at TP8 is just a trickle at this
time. It is emergin-q out from under a fallen tree and root wad. But this aRRears to be a well defined channel
downstream from this point as indicated by washed gravels In the bottom and defined banks. No vegetation
is growing In the channel bottom but is growinct along the low banks.
At 320 feet southwest from the SW property corner, and. downstream from the seepage point at TP8,
there is slough sedge (Carex obnupta, OBL indicator species) that is growing in large clumps at the lower
part along the broad swale where it begins to spread out into the northern part of the "West Hylebos

The subsurface layers are stratified mucky peat,
muck, and peat that formed mostly from sedges. Where
these soils adjoin mineral soils, some layers are 2S
percent wood fragments. Thin lenses of Aineral
soil a half inch to 2 inches thick occur at any
depth below 1S inches in some places, but they make
up no more than S percent of the soil mass.
Some areas are up to 30 percent inclusions of
Tukwila sails, which are deep mucks, and Shalcar
soils, which are shallow over a mineral substratum;
and some areas are up to 15 percent inclusions of
the wet Bellingham and Norma soils. Total 'inclusions
do not exceed 30 percent.
Permeability is moderate. There is a seasonal
high water table at or near the surface. If the
water table is controlled, the effective rooting
depth is 60 inches or more. rn undrained areas,
rooting depth is limited. The available water capac-
ity is high. Runoff ponds, and there is little or
no erosion hazard.
This soil is used for seeded grass pasture, hay,
blueberries, and truck crops. Capability unit IIw-3;
no woodland classification.
Shalcar Series
The Shalcar series is made up of very poorly
drained organic soils that are stratified with miner-
al soils and overlie mineral soil material at a
depth of 16 to 30 inches. These soils formed in
deposits of sedge peat and alluvium in the stream
valleys and on rolling, glaciated uplands. Slopes
are 0 to 1 percent. The annual precipitation is 35
to 80 inches, and the mean annual air temperature is —
about 50° F. The frost -free season ranges from 150
to 200 days. Elevation ranges from 25 to 750 feet.
In a representative profile, the surface layer is
very dark brown muck about 14 inches thick. Below
is is 5 inches of grayish -brown silt loam and

The muck and mucky peat layers range in color
from black to very dark brown, have a combined thick-
ness of 16 to 28 inches, and occur within a depth
of 32 inches. Thin layers of mineral soil material
also occur within this depth in places. The mineral

mottled very dark grayish brown, gray, and olive
gray.
Some areas are up to 30 percent inclusions of the
very deep muck and mucky peat Tukwila and Seattle
soils; and some areas are up to 15 percent the poor-
ly drained Norma, Bellingham, Puget, and Snohomish
soils. Inclusions make up no more than 30 percent
of the total. -acreage.
Permeability is moderate in the organic layers
and moderate to rapid in the lower part of the pro-
file. There is a seasonal high water table at or
near the surface. If the water table is controlled,
the effective rooting depth is 60 inches or more. In
undrained areas, rooting depth is restricted. The
available water capacity is high.. Runoff is ponded.
There is no erosion hazard.
This soil is used for row crops and pasture. Ca-

J oscph Pircey Property Sensitive Areas Assessment
and Review of Wetland Verification Reports
by John Comis Associates
30879H
As requested by the City of federal Way, on August 30, 2006 Suzanne Bagshaw. and Stephanie
Smith conducted a field visit to the Pircey property located at 803 South 348r". Street in Federal Way.
Washington. Tlie purpose of the site visit was to deternnc whether jurisdictional wetlands or
streams arc located within approximately 300 feet of the subject property, and to evaluate the
wetland verification reports by John Comis Associates QCA) listed below for consistency with
Federal Way City Code. 'Towards that end, we reviewed the following documents:
• Wetland Verification For the Joseph Pircey Site @ federal Way by John G. Comis of John
Comis Associates, dated February 21, 2005; stamped Received by the City of Federal Way
Building Dept. Junc 6, 2006;
• Wetland Verification for the Joseph Pircey Site @ Federal Way by John G. Comis of John
Comis Associates, dated February 18, 2006; stamped Received by the City of Federal Way
Building Dept. June 6, 2006;
• United States Department of Agriculture, Washington Soil Survey Reports,
http://ww-,v.or.rites.usda.gov/pnw_soil/wa_reports.html, September 14, 2006; and
• Federal Way City Code (MCC).
Summary:
• As required by FWCC 22-1 (Wetland Definition), John Corms Associates QCA) followed
methodology specified in the March 1997 IPashington Slate Vetlands Ideni acation and Delineation
Afanural (Department of Ecology publication No. 96-94) to identify wetlands.
• We agree with the conclusions of the JCA wetland reports that there are no jurisdictional
wetlands or) the subject property, or within approximately 100 feet offsifc to the west or south. -

1 More information will be required relgarding the sizes, ratings, and locations relative to the
subject property of the wetland associated with the stream and the western wetland south of the
old stormwater pond.
We Iocated a wetland that was not identified in the JCA reports, this additional wetland is
" located approximately 150-200 feet southwest of the subject property Q
t More
information regarding the size and rating of this wetland anditslocation relative tTP ) he subject
Property will be required.
• It appears that the section of the drainage course that satisfies I,WCC criteria for a regulated
l stream begins north (upstream) of location identified in the JCA reports - at approximately 70
feet southwest of the subject parcel instead of 230 feet. We also located a drainage ditch along
the western boundary of the subject property that was not identified in the JCA reports. The
ditch may be connected to the stream, and so it may also be jurisdictional. In order to determine
the extent and location of the jurisdictional stream, more information will be required regarding
• the connectivity of surface flow through the ditch-swale-stream system during the rainy season.
With the exception of the old stormwater pond, wetlands located west or south of the subject
parcel are likely to be rated as Category I either because they are part of the large Category I
wetland located in `Vest Hylebos Wetlands State Parls (Federal Way Wcdand Inventory # 20-21.-
4-121), or because they arc hydrologically and/or functionally associated with that wetland
(FWCC 22-1). Category I Wetlands have a 200-foot buffer [FVV'CC 22-1357 1 r
Any regulated stream located west or south of the subject parcel is likely to be)( ted is Major
Stream because it is likely to be a tributary to IIylebos Crcek which is salmon -bearing (FWCC

Results of the Site Visit and Review of the JCA Wetland and Stream Verification Reports
The Pircey property is located at 803 South 348`s Street. T1,v0 houses and associated small
outbuildings are located on site. West .T.-Iylebos Wetlands State Park is located diagonally southwest
from the southwest property coiner. John Comis Associates performed two visits to the Pircey
property on I'cbruary 1, 2005 and January, 14, 2006. They followed methodology specified in the

identify wetlands on the subject property and in areas adjacent to the
south and west sides of the subject property. JCA used a hip -chain to measurc distances to their test
pits, therefore those distances are only approximations. Because the string lines are laid down as one
wallas over rough ground, scrambles over fallen trees, through dense vegetation, and around
impenetrable vegetation, the lines arc not straight. As a result, actual distances are likely to be shorter
than those measLu•ed with ahip-chain., The longer the measure

JCA TP 3, but we were able to identify its approximate location. We dug test pits at all of those
locations and at other additional locations. Copies of our data sheets (Otak 1P1 — 11'8) are included
at the end of this memorandum.
The JCA reports conclude that there are no wetlands located on the subject property, within 220
feet west of the subject parcel, or within 300 feet southwest of the subject parcel. We disagree with
these conclusions. We identified a non -jurisdictional wetland onsite, and an additional wetland
located approximately 150-200 feet west southwest of the subject property (discussed in more detail
below). The JCA reports identify two wetland areas approximately 220 feet west of the subject
parcel, one of which appears to be an old stormwater detention pond located just south of S. 348's
Street The second wetland to the west is located south of the stormwater pond. The J CA reports
also identify a wetland associated with the drainage course located approximately 300 feet southwest
of the subject property. We agree with the characterizations of those wetlands; however more
precise information regarding their locations relative to the subject property is required (see below).
The JCA reports conclude that the drainage course which flows from north to south becomes a
regulated stream at a point approximately 230 feet southwest of the subject parcel. We disagree with
that conclusion. We found that the drainage course satisfies the criteria for a jurisdictional stream
closer to the subject property —possibly as close as 70 feet (see below). We located a drainage ditch
adjacent to the west side of the subject property that is not identified in the JCA reports. It is
possible that the ditch night satisfy the criteria for a jurisdictional stream (sec below).
Wetlands
The JCA site visits were performed during the winter (February 2005 and January 2006). Although
winter is a good season for observing hydrology, most herbaceous and deciduous species are
dormant at that time. As a result, many herbaceous species were not present in the JCA sample
plots. In addition, some indicators, such as oxidized rhizospheres, are absent when roots are not
actively growing. Seasonal differences account for many of the specific differences between the JCA
data sheets and the Otak data sheets.
JCA TP 11.9 the only test pit located on the subject property that is documented in the ]CA reports.
It is located in a low spot in the lawn near the southwest corner of the property (see attached copy
�y of JCA Field Note Sketch Map Figure 6). We disagree with the JCA conclusion that JCA'11' 1 is
L� upland. We agree that the sample area is dominated by hydrophytic vegetation, but we also found
distinct mottles in a 2.5YR 6/2 sandy clay from 5-12 inches below the surface, and oxidized root
channels above 12 inches (see the attached data sheet for Otak TP 1). As a result, Otak TP 1
satisfies all three criteria necessary for wetland determination. T.-Iowever, the area appears to be
isolated and significantly smaller than 2,500 square feet, so the wetland is probably not jurisdictional
under Federal Way City Code (FWCC 22-1).

We agree with most of the JCA conclusions for the offske test pits. We agree that JCA TP 3, 5; 6, 7,
and 8 are upland plots because they do not satisfy all three criteria (hydrophytic xegetation, hydric
soil, and hydrology) required for wetland determination (see data sheets for Otak TP 3 —.TP 5).
Although JCA TP 7 and 8 are not wetland plots, they are associated with a seasonal stream (see
stream section below).
The JCA reports identified JCA TP 2 and 4 as upland plots in 2005, but identified them as very
small isolated wetlands in 2006. Based on the dominance of vine maple (Acer zx nalum, FAC-) and
other non-hydrophytic species, we determined that both of these sample plots arc upland areas (see,
data sheets For Otak �.l`P 2 and 8). JCA TP 2 appears to be associated with a seasonal strearn, and
JCA TP 4 appears to be associated with a ditch/drainage swale system which may be a jurisdictional
stream (sec stream section below).
We agree with the JCA conclusion that the old stormwater pond located tvest of the subject
property (south of S. -348'b Street) is a wetland (see data sheet for Otak TP 7). We also located a
wetland south of the storm pond. This forested wetland is dominated by alders (A. lnus rubra, FAC),
with salmonberry (Rmbw speclabilis, FAC+) and slough sedge (Carer obnupta, OBL) in the understory.
This wetland is probably the western wetland identified in the JCA reports. We also located the
stream -associated wetland that is identified in the JCA reports south ofJCA TP 8 (south southwest
of the subject property). The wetlands may or may not be located within 200 feet of the subject
property —more accurate information is necessary. Although we did not delineate them, the
wetlands, other than the stormwater pond, are likely to be hydrologically connected to the Category
I wetland to the south. If so, they would also be rated as Category 1. FWCC requires 200-foot
buffers for Category I wetlands.
Additional Wetland
We located an additional wetland west southwest of JCA TP 2 (sec data sheet for Otak TP 6). This
wetland may be within 200 feet of the subject property. The scrub -shrub wetland is dominated by
vine maple and salmonberry, with skunk cabbage in the understory. Even after an extremely dry
summer, the 10YR 3/ 1 clay was so moist that it vas nearly saturated at two inches below the
surface. The wetland is located west of the ditch -Swale -stream system (see stream section below) in a
southward sloping, wide Swale -like area, Although we did not delineate the wetland, it is likely to be
hydrologically connected to the Category I wetland to the south. If so, the additional wedand would
also be rated Category I. further investigation will be necessary to determine the size and rating of
this additional wetland and its location relative to the subject property.
Stream and Drainage Ditch Characterization
The JCA reports identify a regulated stream which flows from north northeast to south southwest
beginning approximately 230 feet southwest of the subject property, in the vicinity of JCA TP 8
IC\p toiect\30800\30879H \ Reports Vircep092606M.doc

(Otak TP 4). Although we agree that there is a seasonal regulated stream, we conclude that the point
at which the drainage course satisfies FWCC criteria for a regulated stream (FWCC 22-1) begins
further upstream, closer to the subject property. There is a clearly defined channel at JCA TP 7
(Otak TP 3) approximately 175 feet southwest of the subject property. Although somewhat less
clearly defined, there appears to be a channel close to JCATP 2 (Otak TP 2), approximately 70 feet
southwest of the subject property. FWCC requires 100-foot buffers for Major Streams. North of
JCA TP 2 there is a broad, vine maple dominated, swale-like depression, This drainage
swale/depression runs close to the western boundary of the subject property, and it appears to be
the upstream continuation of the stream channel —we observed some evidence of flow in it.
We located a drainage ditch along the central portion of the western side of the subject property that
is not identified in the JCA reports. The ditch takes a sharp turn away from the subject property in
the vicinity of JCA TP 4 (Otak TP 8). Shortly thereafter, the ditch becomes less defined and it
outlets into the drainage swale/depression that extends southward (downstream) to JCA TP 2. If
surface flow from the drainage ditch continues through the swale/depression into the defined
stream channel, it is possible that the drainage ditch may be a jurisdictional stream. As previously
mentioned, FWCC requires 100-foot buffers for Major Streams.
The only way to make an accurate determination as to the extent and location of the jurisdictional
stream is to re-examine the ditch-swale-stream system during the rainv season to assess surface flow
and connectivity. rRA-,�- 15 f4 -=
C, Q
Additional Information Required
Additional information is required regarding the estimated size and subsequent ratings and
buffers, and locations relative to the subject property of the wetland associated with the stream
(south of JCA i'P 8) and the wetland west of the site (south of the old stormwater pond).
Distances from the subject property to the wetlands and streams offsite should be provided by
an actual survey, not estimated by hip -chain in order to more accurately determine the extent of
required buffers relative to the property lines.
Additional field information is required regarding the size and rating of the additional wetland
that we observed (Otak 1'P 0) and its location relative to the subject property.
In order, to determine the extent and location of the jurisdictional stream, it will be necessary to
field confirm conditions regarding the connectivity of surface flow through the ditch-swale-
stream system when soils are completely saturated and surface flows most likely to be present.

REMARKS:
John Comis Associates (JCA) has completed a site visit and field investigation at the subject
property. This work included a routine onsite determination of "regulated wetlands" that exist
within the site boundary. i The field investigation also includes a reasonable effort to find offsite
wetlands that may be located within 315 feet Z of the site boundary. The identification and
delineation of "regulated wetlands" is made in accordance with the City of Federal Way Critical
Area Regulations for wetlands per the current Federal Way Municipal Code (FWMC).
We have reviewed the "Technical Memorandum" by Otak dated September 29, 2006, to the City
of Federal Way, and find that there are offsite jurisdictional wetlands that they identified and
flagged on 8/30/06 near the subject property. At this time, I would like to thank them for such a
Wetlands are delineated using the Washtngran .Srpte Wetlands ldenriPrrnlian and f?alinearl r Mon , March 1997, prepared by
the Washington State Department of Ecology (WDOE Publication #96-94). This State Wetlands Manual is required to be used by all
state agencies in the application of any state laws and regulations as well as any city or county in the implementation of any
regulations under the Grovah Management Act. This methodology used is also consistent with the 1987 SyrQJ.QLEiJgirteers liretlairu!

The 315-root distance is the maximum buffer width for the highest rated Category I wetland, plus 15 feet for building setback.
This represents a distance from which a `regulated activity" should not impact a "regulated wetland".

through review of the onsite and offsite areas and respectfully request a field meeting with their
wetland biologist at the site to discuss some of the findings and our recommendations for this
site.
The data points are flagged with colored ribbon marked as follows:
• "WETLAND DELINEATION -number" (pink ribbon, tied to wooden stakes or vegetation, see
circled points on sketch map)
• "TEST PLOT -number" (blue and green ribbons, tied to wooden stakes or vegetation, see triangles
on sketch map) (Note that. JCA has marked TP's #1 thru #8 dated 1/14/06; TP's #9 thru #13 dated
10/19/07 are done for this verification of offsite wetlands and streams)
• "TRANSECT-distance" (blue ribbon, as measured by JCA hip -chain and tied to vegetation)
• "FLAGGING BY OTAK" (pink&black stripped ribbon, tied to vegetation, see points marked
"TH#" dated 8/30/06 on flags tied to vegetation as noted on the JCA sketch map)
The enclosed field note sketch maps (FNSM) and aerial photo map show numbered data points
such as the test plots (TP), transect lines, habitat features such as large trees, landmarks such as
houses, surveyed property corners, drainage features and various other site -specific information
that we have noted based on our field investigations.
The location of the property corners are based on the actual property survey that was recently
done by EMS Engineering. We have used these property corner locations as a basis for offsite
wetland and stream corridor locations that are plotted to scale on the aerial photo map included
with this memorandum.
SUMMARY OF WETLAND AND STREAM FINDINGS:
The offsite wetland that we found located southwest of the southwest property corner is herein
designated as Wetland "A" by this study. Generally, Wetland A appears to be a "slope wetland"
and appears to be a headwater wetland associated with a stream or tributary area that drains
farther offsite to the southwest.
Wetland A is located more than 150 feet from the southwest property corner. We measured the
distance from the closest edge of Wetland A to the subject site and found that this distance is
more than 156 feet measured by JCA with hip -chain. This appears to be the same wetland
described in the "Technical Memorandum" by Otak for the data point marked on the pink and
black stripped flag at "TH6", dated 8/30/06.
Please note that Wetland A is located entirely offsite from the subject property. Offsite wetlands
and streams are located as shown on the maps included with this memorandum but these areas
are not located or delineated in detail. This is due to their being on adjacent private property that
we do not have permission to survey in detail. We believe it would be a liability to us and to the
client if the City were to require any further detail delineation of offsite areas.
Also note that earlier onsite and offsite investigations were done by JCA during winter wet
periods (February of 2005 and January of 2006) when saturation and/or inundation was found to
be present in the identified jurisdictional wetland areas. At this time (October of 2007) there is
groundwater saturation or "interflow" that we found on 10/19/07 indicating subsurface flows
along a drainage corridor at a point that is near the south boundary of the site.

Vegetation classes within Wetland A are identified and generally characterized in accordance
with Cowardin et al 3 as follows:

SYSTEM
CLASS WATER REGIME
abbreviation
A
Mustrine
Scrub -Shrub/ Saturated *
emergent
(PSS/emB)
* saturated (B): substrate is saturated for an extended period during growing season but surface water is
seldom present
Wetland A is classified as "slope" by the WDOE hydrogeomorphic classification system.
Wetland A is rated Category III based on the 4-tiered system of the "Washington State Wetlands
Rating Systemfor Western Washington", August 2004, revised 2006 (WDOE Pub #04-06-025).
Wetland A appears that it may be rated Category II or III by the FWMC definitions (see
Appendix 1, part E, for details). If it is "contiguous with water bodies or tributaries to water
bodies which under normal circumstances contain or support a fish population, including streams
where flow is intermittent, then it may be a Category II wetland. However, further study of this
offsite area may show that Wetland A does not have direct surface connection to a downstream
water body and therefore may be rated Category III.
A standard buffer width is required to be 100 feet for a Category 11 wetland in accordance with
FWMC requirements (see Appendix 1, part E for details). A minimum building setback (BSL)
of 15 feet is also required to be measured from the edge of a wetland buffer.
A small drainage Swale (unnamed) appears to extend to a point near the southwest corner of the
site. However, we found that the upper -most end of sub -surface "interflow" is 53 feet south of
TP2. This is located on the FNSM at TP13. At TP13 we found sub -surface water in a test hole
to be at 10" to 12" deep. This was measured just below the duff layer in relatively undisturbed
offsite area [See FNSM page 7 for details]. Where saturation was found in this test hole, we
noted that there was no apparent flow but groundwater saturation and freewater were present at
depth. Furthermore, we noted that there was no saturation or freewater present in a test hole that
was dug to a depth of 15 inches located at TP12 just 12 feet north of TP13 (this corresponds to a
location 41' south of TP2 which is located 50 feet south of the surveyed property line).
Therefore, we conclude that the closet point of sub -surface flow is 103 feet south of this site.
This location is the closest point of a stream corridor to the south side of this site; and a 100-foot
stream buffer does not extend into the subject property. Note that for a watercourse to be
classified as a "stream" by the FWMC, it must have an ordinary high water mark which this
stream corridor does not have as it is sub -surface flow in the area of the site (see Appendix I for
details).
An emergent surface drainage course is located 160 feet south of TP2. TP2 is located 50 feet
south of the surveyed property. Therefore, the surface drainage course is more than 200 feet
south of this property.
Offsite wetlands and the stream corridor that are within 300 feet of the subject property are NOT
influenced by drainage from this site. The stream corridor within 300 feet of the property is not

Park. There are no'salmonids that are known to migrate this far into the upper part of this
watershed.
I believe this concludes our wetland and stream reconnaissance for this area. I think that we can
meet with the Otak wetland biologist at the site to review these data and information if they feel
it is necessary. I understand that the City has recommended that we do meet with them to resolve
any differences. Please feel free to call me if you have any questions about our field data,
findings or conclusions.

APPENDIX 1
METHODOLOGY FOR WETLAND
DETERMINATION AND DELINEATION
McHugh (Pircey) Site @ Federal Way
By John Comis Associates
Date: 10/26/07
METHODOLOGY
A. APPROACH USED FOR WETLAND DETERMINATION
Wetlands are identified using the Wasfzington Stale Wetlands Idenlificalion and Delinealion
Manual, prepared by the Washington State Department of Ecology (WDOE), Publication #96-94,
dated March 1997. The 1997 WDOE Wetlands Manual is required to be used by all state
agencies in the application of any state laws and regulations as well as any city or county in the
implementation of any regulations under the Growth Management Act.
The US Army Corps of Engineers, Seattle District has reviewed this manual method and
approved it as a revised version of their corps ofEVJneers Wetlands Delineation Manual,
Technical Report Y-87-1, January 1987. The State Manual incorporates the amendments and
clarifications in the 1991 and 1992 documents published by the COE that reflect more current
technical information developed since the original COE Manual was published. It is the intent of
the State Wetlands Manual to result in the identification and delineation of the same areas as
would be identified and delineated under the COE Manual as may be applied for Federal
reviews.
The "criteria" which an investigator must use to determine if a test plot is a "wetland" are limited
to the presence of all 3 wetland criteria: hydrophytic vegetation, hydric soils, and wetland
hydrology. This means that to make a positive wetland determination, all 3 criteria must be
positive. The absence of one, two, or all three of the criteria should result in a non -wetland
determination. The presence of dominant "field indicators" is used to determine if a criterion is
met. If a field indicator is absent, then an indirect indicator may be used. For example, the
absence of inundation or saturation during a dry summer field investigation could result in the
hydrology criterion not being met. However, the presence or absence of encrusted detritus on
twigs or blackened leaves on bare ground in a depression may be used to help verify sufficient
inundation during a wetter period of the growing season.
The State Manual stipulates 3 key provisions of the definition of wetlands include:
a. Inundated or saturated soil conditions resulting from permanent or periodic
inundation or saturation by ground water or surface water (saturation within 12 inches of the
surface for at least 20 to 30 consecutive days during periods in the Mesic growing season [March
thru October]).
b. A prevalence of vegetation typically adapted for life in saturated soil conditions
(hydrophytic vegetation).
c. The presence of "normal circumstances".
The selection of a specific method and procedure for identifyin wetlands may follow one of the
following methods:
■ the "routine determination method" for undisturbed and non -problem area wetlands;
• the "offsite determination method" for areas within 300' of the site boundary; and/or
• the "disturbed area and problem area wetland determination procedures" for areas with
disturbed or atypical vegetation, soils or hydrology. If an area is disturbed, then a higher
level of analysis such as a "Comprehensive" determination method may be required.
The preferred and simplest method is the "ROUTINE Determination Method" for ical,
generally undisturbed areas with normal environmental conditions. The routine method is used
in areas where the vegetation, soils and hydrology condition can be readily observed.
McHugh (Pircey) Site @ Federal Way

Date: 10/26/07
For areas that are complex, atypical, disturbed or altered environmental conditions, a
"COMPREHENSIVE Determination Method" may be used. The comprehensive method
employs transect sampling procedures that may require deeper test holes to be dug in areas that
have been filled or graded.
Generally, the investigator is looking for a portion of the site (called a test plot) where a "typical
condition" exists --where a well established plant community is present with no evidence of
recent clearing, grubbing, filling, grading, or soil drainage activities. This situation should occur
during a period when "nonnal circumstances" are present. That is during periods of the year
when normal environmental conditions such as moderate rainfall and average antecedent
moisture conditions (AMC) exist within a wetland or a watershed area.
For the hydrophytic vegetation criterion to be met, a dominant number (i.e. more than 50%) of
"OBL, FACW and/or FAC" indicator species must be present in the sample plot (see the
discussion of these abbreviations in a later section of this appendix). The vegetation analysis is
based on the 3 dominant species in each of 4 vegetation layers (or strata: trees, saplings/shrubs,
herbs/grasses, and woody vines). Or if only 1 or 2 vegetation layers exist at the test plot, then 5
dominant species are used to make the determination.
If a test plot has no well established vegetation due to recent clearing and grubbing, or the soils
have been severely disturbed due to excavation, filling or grading activities, the test plot is called
an "atypical situation". In atypical or disturbed situations the wetland determination may be
based only on soil borings into the undisturbed soil stratum below the fill line and by hydrology
criteria. If an area is disturbed, then a higher level of analysis such as a "comprehensive"
determination method may be required.
The procedure used for each test plot is indicated on the individual data sheets. The
environmental conditions that exist at the site on the day of the field investigations are indicated
in field notes and marked in the appropriate "normal" (or not normal) blank at the top of the data
sheet. If the vegetation, soils or hydrology are found disturbed, this is explained at the bottom of
the sheet. The results for each test plot are recorded on data forms and included with this report
in Appendix 2.
B. KEY DEFINITIONS USED
For this study, "wetlands" are defined using the adopted .State of Was laingtor�'s Gsotivth
hfanagenrenl Act definition:
"Those areas that are inundated or saturated by surface water or ground water at a
frequency and duration sufficient to support, and that under normal circumstances do
support, a prevalence of vegetation typically adapted for life in saturated soils
conditions. Wetlands generally include swamps, marshes, bogs, and similar areas."
(Corps of Engineers Regulation 33 CFR 328.3, 1988)
"Wetlands do not include those artificial wetlands intentionally created from non -
wetland sites, including but not limited to, irrigation and drainage ditches, grass -lined
swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and
landscape amenities, or those wetlands created after July 1, 1990, that were
unintentionally created as a result of the construction of a road, street, or highway.

Wetlands may include those artificial wetlands intentionally created from non -wetland
areas to mitigate the conversion of wetlands."
Other key definitions may also apply which are defined in the City of Federal Way Municipal
Code (FWMC), Chapter 18 and 22 for Regulated Wetlands, current Ordinance 06-536, passed
November 7, 2006 [note the 3-tiered rating system, see part E. of this appendix for details].
C. WETLAND DELINEATION CRITERIA
By Vegetation:
For this study, vegetation was primarily used, along with the soils and hydrology criterion, to
delineate the edges of the identified wetland areas. This was due to the general lack of
disturbances within the forested areas of the site. For wetland plant community delineations, we
used vegetation that exists along the wetland margins where plants were well established and
represent typical and normal conditions between hydrophytic and upland conditions.
Plant communities were analyzed in detail and vegetation data were documented on Field Data
Sheets for the individual test plots (TP, or sample plots) shown at locations on the report figures
and on our field note sketch maps. The onsite analysis test plot data were extrapolated into the
areas shown by JCA as "upland" on the Field Note Sketch Maps (FNSM, see Appendix 2).
For this study, a species is considered dominant in a test plot if more than 10% of the plants
growing in that area appear to be the same species. This is an estimate of the relative density of a
species in a sample area. By routine methods, this is usually made by visual inspection of the
dominant plants in a representative sample area. As defined in the 1997 State Manual, a
dominant species exerts a controlling influence on or defines the character of a plant community.
Dominance on the other hand is used as a descriptor of vegetation that is related to the standing
crop of a species in an area, usually measured by height, aerial cover, or basal area (for trees).
This should not to be confused with a vegetation class that must comprise more than 30% of the
aerial cover in the entire wetland (or upland).
If more than 50% (i.e. 51 or more percent) of the dominant plant species in a test plot are OBL,
FACW and FAC, then the hydrophytic vegetation criteria is said to be met and it is marked "yes"
on the field data form.
The specie identifications are based on available plant keys such as Hitchcock and Cronquist's
Flora of the Pacific Nonhwes! (1973). To determine whether plant species exhibit hydrophytic
adaptations, if they are native or non-native (introduced), and which strata (tree, shrub, herb)
they normally occupy, we use the National List of flans Species That Occur in Wetlands:
Northwest (Rion 9), published by the US Fish and Wildlife Service, May 1988. The indicator
statuses for the various species found in the area are determined based on the National List
together with the December 1993 supplement for the Northwest Region.
The indicator status describes the estimated probability of a plant species occurring in wetlands.
Indicators are:
OBL = Obligate Wetland species ("almost always occurs", >99% probability)
FACW = Facultative Wetland species ("usually occurs", 67-99% probability)
FAC = Facultative species ("equally likely to occur", 34-66% probability)
FACU = Facultative Upland species ("usually occurs in non -wetlands", 67-99% probability)
UPL = Upland species ("almost always occurs in non -wetlands", >99% probability)
McHugh (Pircey) Site @ Federal Way
By John Comis Associates
Date: 10/26/07
NI = No Indicator assigned (If a species does not occur in wetlands in any region of the National List, then
"no indicator is assigned".)
+ = Slightly more frequently found in wetlands
- = Slightly less frequently found in wetlands
* = Tentative assignment based on either limited information or conflicting reviews from the 1993
Northwest Supplement of the National List.
Parenthesis () around an indicator signifies the status is assigned by JCA, and a question mark (?) after an
indicator signifies it is tentative based on our (JCA) field experience & observations.
By Soils:
For wetland soil determination, we use the hydric soil criterion prescribed in Part III of the
Washington State Manual. Hydric soils are defined as "a soil that formed under conditions of
saturation, flooding, or ponding long enough during the growing season to develop anaerobic
conditions in the upperpart. " (USDA-NRCS 1995, Federal Register, 7/13/94, Vol. 59, No. 133,
pp. 35680-83). Note that the definition and criteria for hydric soils may change periodically as a
result of revisions by the National Technical Committee for Hydric Soils (NTCHS). In general,
this occurs in the upper 12" of the soil profile and usually for 20 or more days during the period
when soil temperatures are above biologic zero (410F).
In general, "organic hydric soils" develop as a result of prolonged anaerobic conditions with long
periods of saturation impeding decomposition (peat or muck) and have greater than 16" of
organic matter in the surface layer (Histosols). "Mineral hydric soils" have less than 16" of
organic matter (if some is present, then it may have a'histic epipedon'). They are saturated for
more than 20 consecutive days during the growing season (the period when soil temperatures are
above biologic zero, 41OF, as defined by "Soil Taxonomy", 1975; usually March -October), and
contain dominant gleying and/or mottling.
The soil color and/or presence of mottling and gleying in a sample are primary field indicators of
whether a mineral soil is either hydric or non-hydric. Non-hydric soils are generally a rusty red
or yellow color. Hydric soils are generally black, gray, or washed out in color. A field indicator
for a saturated organic hydric soil is a rich black matrix color of say 2/1 or 2/2. A field indicator
for a saturated mineral soil is a leached matrix color of say 3/1 or 4/1 or 5/1 or 6/1). A hydric
mineral soil must have a low chroma color feature (at least 1 if not mottled, or a chroma 2 if
prominent mottles are present in the soil matrix).
Gleying and prominent mottling are color indicators of prolonged saturation and indicate that
anaerobic conditions probably exist for sufficient periods of time to develop wetland soils.
Gleyed soils are generally bluish -green to grayish -green in color throughout the soil mass or in
mottles (spots or streaks) interspersed within the dominant soil color (matrix color) in a layer
(soil horizon). Gleying results from the leaching of the dissolved (reduced) iron and manganese
minerals out of the soil matrix. Soils gleyed to the surface or to the surface layer of organic
material are generally considered hydric. Soils that are saturated throughout the year are usually
uniformly gleyed to the surface (Tiner and Veneman 1987).

Redoximorphic features 4 or "mottles" are generally yellow to reddish brown blotches or spots
accumulating in mineral soil due to a fluctuating water table during the growing season. The
size, number and color of mottles reflect the duration of soil saturation and thus whether the soil
is hydric. Mottling in hydric soils should be "distinct" or "prominent" in the upper horizon.
Mineral soils that have a grayish matrix (chroma 2 or less) with mottles are hydric if the mottles
are not relict mottles. Mineral soils with a predominantly brown or yellow matrix and light gray
mottles are not usually hydric. s
The National Technical Committee for Hydric Soils has developed criteria for identifying hydric
soils and a list of the Nation's hydric soils is maintained by the National Resource Conservation
Service (NRCS [formerly Soil Conservation Service, SCS], 1987). A federal manual has also
been published by the USDA-NRCS that describes methods and limitations for identifying hydric
soils for the National and State lists.
The NRCS maintains the list of hydric soil map units for each county in the US. The list is used
for identifying which soils are hydric based on the local soil series descriptions. These soil series
descriptions for soil map units are indicated by this study as within or associated with the project
site. The soil descriptions for the mapped areas may be found in the 1973 [NRCS] Soil Survey of
King Coun .

For the wetland hydrology determination, we use the presence of inundation and/or saturation for
a sufficient "hydroperiod" to determine whether hydrology criteria are met. The depth to
freestanding water in a pit or soil probe hole must be less than 12" in wetland margins where
hydric and upland soils and vegetation are transitional. Topographic elevations, encrusted
detritus or debris, silt lines, hydraulic gradients, capillary fringe, or a drainage analysis of offsite
and onsite tributary areas are other means and indicators that may be used to help determine the
presence or absence of sufficient hydrology for a positive wetland determination.
After a wetland determination is made, the wetland area is analyzed to determine if it is a high
quality wetland or if it has any of several irreplaceable ecological functions. The wetland is then
analyzed for any significant habitat values such as size, classifications, plant species diversity,
structural diversity, special habitat features, buffer conditions, and connection to streams or other
habitat areas.
D. WETLAND CLASSIFICATION
Wetlands identified by this study are classified using a hierarchical multi -level approach
developed by the US Fish and Wildlife Service for their scientific classification system. The
classification system is published in the report titled Classification ofWellcrnrls cnrd Dew Water
Habitats of the Unifed Slugs, FWS/OBS-79/31, by Cowardin, et al. (December 1979).
The system of classification divisions is based on habitats that share the influence of similar
hydrology, geomorphology, chemical, or biological factors. The wetland systems involved in the
"Redoximorphic features" are formed by the processes of reduction, trans location, or oxidation of Fe and Mn oxides
(formerly called mottles and low chroma colors). Redox concentrations (reddish mottles) occur as pore linings along
root channels and ped faces (Vepraskas, 1994). "Distinct" and "prominent" are defined in the glossary of the reference
text Field Indicators of Hydric Soils in the United States.

project site are generally limited to "palustrine" systems. Palustrine wetlands (these are the only
wetlands identified by this study) are divided into classes and subclasses determined by dominant
vegetation such as "emergent" (EM), "scrub -shrub" (SS) and/or 'forested" (FO), "aquatic bed"
(AB), and/or "open water" (OW). Water regimes are assigned for each class based on the
hydroperiod or duration of flooding (inundation) or saturation associated with the wetland area.
These are defined for freshwater, non -tidal areas as follows:
WATER REGIME MODIFIERS [NON -TIDAL]
temporarily flooded (A): flooded (inundation by surface water) for brief periods during growing
season but the water table is otherwise well below the soil surface
saturated (B): substrate is saturated for an extended period during growing season but surface
water is seldom present
seasonally flooded (C): flooded for extended periods during the growing season, but usually no
surface water by the end of the growing season
seasonal] flooded/welI drained (D)
seasonally flooded/saturated (E): flooded for periods, but usually saturated by groundwater at or
near the surface thru most of the growing season
semipermanently flooded (F) flooded throughout growing season in most years, when surface
water is absent, water table is at or near the surface
intermittently exposed (G): flooded throughout year except in years of extreme drought
permanently flooded (H): flooded (water covers land surface) throughout the year in all years
intermittently flooded (J): surface is usually exposed with surface water present for variable
periods with no seasonal pattern
artificially_ flooded (K)
intermittently flooded/temporary (W)
saturated/semi-peniianent/seasonal (Y)
intermittently exposed/permanent (Z)
unknown (U)
SPECIAL MODIFIERS
beaver (b)
partially drained/ditched (d)
farmed (f)
diked/impounded (h)
artificial substrate (r)
spoil (s)
excavated(x)
The class of a particular wetland describes its general appearance in terms of either the dominant
vegetation or the substrate. When over 30% cover by vegetation is present, a vegetation class is
used (e.g., "emergent", "scrub -shrub" and/or 'forested"). When less than 30% of the substrate is
covered by vegetation, then a substrate class is used (e.g., "unconsolidated bottom", "aquatic
bed', or "moss -lichen"). Typical demarcations of these classes of palustrine wetland systems are
shown in the Cowardin report. [Also reference is made to the current (1988) National Wetlands
Inventory (NWI) map and legend.]
Wetlands that have a single vegetation species that dominate 90% of the total wetland area are
called a "mono -type". This may occur where more than the one species is present but the total
area of their coverage is less than 10%. If another vegetation class or species dominates more
than 10% of the wetland, then it has higher habitat diversity. This can be based on the number of
plant species found in a class, the number and quality of the structural layers and the

interspersion of classes which creates increased "edge effect" and habitat diversity. This may
also result in a higher wetland "rating".
E. CITY OF FEDERAL WAY CRITICAL AREA REGULATIONS AND
BUFFER STANDARDS
Chapter 18, ENVIRONMENTAL PROTECTION, Definitions:
"Wetlands" means those areas that are inundated or saturated by surface or groundwater at a
frequency and duration sufficient to support, and that under normal circumstances do support, a
prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands
generally include swamps, marshes, bogs and similar areas. The March 1997 Washr?top? Slate
Wetlands ldenlifrcalron and Delineation Manual (Department of Ecology publication No. 96-94)
will be used for identification and delineation of wetlands within the city.
Although a site -specific wetland may not meet the criteria described above, it will be considered
a regulated Welland if it is functionally related to another wetland that meets the criteria.
Regulated wetlands means:
(1) Those wetlands, as described below, which fall into one or more of the following categories:
a. Category I wetlands meet one of the following criteria:
1. Contain the presence of species or documented habitat recognized by state or federal
agencies as endangered, threatened or potentially extirpated plant, fish or animal species;
or
2. Contain the presence of plant associations of infrequent occurrence, irreplaceable
ecological functions, or exceptional local significance including but not limited to
estuarine systems, peat bogs and fens, mature forested wetlands, groundwater exchange
areas, significant habitat or unique educational sites; or
3. Have three or more wetland classes, one of which is open water.
b. Category II wetlands are greater than 2,500 square feet in area, do not exhibit the
characteristics of Category I wetlands, and meet one of the following criteria:
1. Are contiguous with water bodies or tributaries to water bodies which under normal
circumstances contain or support a fish population, including streams where flow is
intermittent; or
2. Are greater than one acre in size in its entirety; or
3. Are less than or equal to one acre in size in its entirety and have two or more wetland
classes, with neither class dominated by non-native invasive species.
c. Category III wetlands are greater than 2,500 square feet in area and do not exhibit
those characteristics of Category I or II wetlands.
"Fish and wildlife habitat, conservation area" means the management of land for maintaining
species in suitable habitats within their natural geographic distribution so that isolated
subpopulations are not created. Habitat conservation areas include but are not limited to such
areas as:
(1) Areas with which endangered, threatened, and sensitive species have a primary association;
(2) Habitats and species of local importance;
(3) Commercial and recreational shellfish areas;
(4) Kelp and eelgrass beds; herring and smelt spawning areas;
(5) Naturally occurring ponds under 20 acres and their submerged aquatic beds that provide fish
or wildlife habitat;
(6) Waters of the state;
(7) Lakes, ponds and streams planted with game fish by a governmental or tribal entity;

(8) State natural area preserves and natural resource conservation areas; or
(9) Streams.
"Streams" means courses or routes, fonned by nature, including those modified by man, and
generally consisting of a channel with a bed, banks or sides throughout substantially all their
length, along which surface waters naturally and normally flow in draining from higher to lower
elevations. A stream need not contain water year-round. In a developing setting, streams may
run in culverts or may be channeled in a concrete, rock or other artificial conveyance system.
This definition is not meant to include irrigation ditches, stormwater facilities or other artificial
watercourses unless they are used by resident or anadromous salmonid fish, or the feature was
constructed to convey natural streams which existed prior to construction of the watercourse.
Chapter 22:
Division 5. Streams
22-1306 Setbacks.
(a) No land surface modification or improvements may take place or be located in a stream or
within the following setback areas except as allowed within this article:
(1) The setback area for a major stream includes all areas within 100 feet outward from the
ordinary high water mark of a major stream.
(2) The setback area for a minor stream includes all areas within 50 feet outward from the ordinary
high water mark of a minor stream.
(b) The setback areas established by this section do not apply to any segment of a stream that is
presently within a culvert, unless that stream will be taken out of the culvert as part of
development of the subject property.

Division 7. Regulated Wetlands
22-1356 Determination of wetland and regulated wetland.
(a) Generally. This section contains procedures and criteria for determining whether an area is
defined as a regulated wetland under this chapter.
(b) Evaluation. If the city determines that a wetland may exist on or within 200 feet of the subject
property, the director of community development shall require the applicant to submit a wetland
report, prepared by a qualified professional approved by the city, that includes the information
set forth in subsections (b)(1) through (b)(7) and (c) of this section. The director of community
development shall use the information required by subsections (b)(1) and (b)(2) to determine if
the area is a regulated wetland and, if so, shall use the information required by subsections (b)(3)
through (b)(7) and (c) to determine the category and the precise boundaries of that regulated
wetland.
(1) An evaluation of whether the area in question is a regulated wetland, based on the definition of
"regulated wetland" in FWCC 22-1.
(2) An overview of the methodology used to conduct the study.
(3) A description of the wetland and plant communities found therein, a map delineating the edge
of the wetland and location of plant communities, and a detailed description of the method used to
identify the wetland edge.
(4) The wetland classification, according to the U.S. Fish and Wildlife Service "Classification of
Wetlands and Deep Water Habitats in the U.S."
(5) A list of observed plant and wildlife species, using both scientific and common names, and a
description of their relative abundance.
McHugh (Pircey) Site @ Federal Way
By John Comis Associates 13
Date: 10/26/07
(6) A list of potential plant or animal species based on signs or other observation.
(7) An evaluation and assessment of the existing or potential functions and values of the wetland
based on the following factors: surface water control; wildlife habitat; pollution and erosion
control; groundwater exchange; open space and recreation; and educational and cultural
opportunities.
(e) Drainage facilities. Surface water ponds, drainage ditches, and other such facilities which
were designed to impound or convey water for an engineered purpose are not considered
regulated wetlands under this article provided they meet all of the following criteria:
(1) The drainage facility must have been intentionally human created. This is to differentiate from
those wetland sites that are accidental consequences of development actions, such as road
construction or culvert placement. Such sites may be considered regulated wetlands by the director
upon a review, under subsection (b)(7) of this section, of the ecological functions and values of the
site.
(2) The drainage facility must have been originally constructed on uplands (nonwetland areas). If
the drainage facility is located within a straightened, channelized, or otherwise disturbed natural
watercourse, it may be considered a regulated wetland by the director upon a review, under
subsection (b)(7) of this section, of the ecological functions and values of the site.
(3) The facility must be actively operated as a surface water drainage facility. Abandoned drainage
facilities may be considered regulated wetlands by the director upon a review, under subsection
(b)(7) of this section, of the ecological functions and values of the site.
(4) Wetland conditions have not expanded beyond the originally constructed drainage facility
boundary. In such a case the expanded area may be considered a regulated wetland by the director
upon review, under subsection (b)(7) of this section, of the ecological functions and values of the
site.
(5) The drainage facility was not designed or constructed as a requirement to mitigate previous
wetland impacts.
(6) The director finds that limited ecological functions and values do not warrant application of the

_ The unit is in a valley, or sueam channel, where it gets inundated by overbank
flooding from that stream or river
_ The overbank flooding occurs at least once every two years.

stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND
IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7
APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use
the following table to identify the appropriate class to use for the rating system if you have several
HGM classes present within your wetland. NOTE: Use this table only if the class that is
recommended in the second column represents 10"/ or more of the total area of the wetland unit
being rated. If the area of the class listed in column 2 is less than UP/, of the unit; classify the
wetland using the class that represents more than 90% of the total area.

McHugh Wetland Verification, 903 South 349* Street, Federal Way, WA
Dear Mr. McHugh:
This letter forwards comments from the City's wetland consultant on reports prepared in conjunction with
development of your property, and identifies the next steps for proposed development.
Grette Report
Grette Associates, LLC was asked to review the Wetland Verification Reports prepared by John Comis
Associates and the peer -review based Technical Memorandum of Review prepared by Otak, Inc. for
wetlands and streams on or adjacent to the above -referenced property. Two copies of their January 17,
2008, Technical Memorandum are enclosed.
r
In their review, Grette summarizes diffc6ngpoints of view etween the two reports, and provides a
means to resolve the matter. They have independently assessed the wetland and stream areas adjacent to
the subject property using post correcw4�QP�.cawdiaates, and identified these areas in Figure 1 of the
report.
Grette also found that the Comis repo goes not provide all relevant wetland information required under
Federal Wqv City Code (FWCQ Section 22-1356 (3) through (7). Grette has listed specific tasks that-V
your wetland consultant must pursue in order for the report to meet adopted standards.
Lastly, Grette confirmed that wetlands iomdted adjacent to the property are Category I wetlands with 2130
foot buffem.• Grette Figure 1 depicts.wedands approximately 145 to 195 few. from the SW pouter of your
property, All other wetland areas are more than 200 feet from the site and the major stre?alt �b been
confirmed as 124 feet fiom the southern property line.
Next Steps
In order to proceed with a development application for this property, the formal land use application must
include a wetland report that addresses the requirements of FWCC Section 22-1356, as well as points
identified in section 5.0 of the Grette report. As discussed at the preapplieation conference for Marista's
Coffee, any improvements, including clearing, grading activities that are proposed within any buffer from
the wetland will require Use Process IV review by the Federal Way Hearing Examiner'. However, if all
' If Process 1V review is required, the wetland report must include analysis of applicable intrusion criteria listed in FWCC
Section 22-1359.

Attention: Deb Barker
Re: McHugh Property — Wetland Review
1.0 Introduction
Grette Associates has contracted with The Ciy of Federal Way (City) to assist in the review of
Wetland Verification Reports prepared by John Comis Associates (JCA) dated February 21,
2005 and February 18, 2006 (Reports) for the Joseph Pircey property. In addition, Grette
Associates reviewed a Technical Memorandum of review .prepared by Otak (Memo), the City's
former environmental consultant dated September 29, 2006. 1t should be noted here that the
property has since changed ownership and is now owned by Mr. John McHugh (Applicant). The
property is located at 803 South 3481h Street in Federal Way, Washington (Subject Property).
The Subject Property is recorded as King County Tax Parcel 2021049067.
2.0 Review
A Grette Associates biologist conducted a thorough review of the Reports prepared by JCA and
the Memo prepared by Otak. The review focused on verifying the accuracy of the Reports and
Memo for compliance with the requirements of the currently adopted Federal Way City Code
(FWCQ Section 22, Article .EV-Critical Areas. In addition, review goals were to examine the
site in an unbiased manner using the best available science in order to determine the nature of
conflicting findings between the JCA Reports and Otak Memo.
A site assessment was conducted on December 181h, 10, and 26", 2007. The site assessment
in a verification of the location of previously identified wetlands and regulated streams.
The off -site wetlands and streams were not delineated at the time of our review. Verification of
wetlands was based on the methodology of the Washington State Department of Ecology's
(Ecology) Washington State Wetlands Identification and Delineation Manual, the US Army
Corps of Engineers' Wetlands Delineation Manual, and associated regional guidance letters.
Stream Typing was based on the stream definitions described under WAC 222-16-030 and
FWCC Section 22-1 Definitions. The Subject Property and accessible adjacent areas were also
assessed for additional wetlands not identified in the JCA Reports or Otak Memo. Once
identified, we utilized post -corrected GPS coordinates to determine the closest extent of wetlands
and streams in relation to the Subject Property boundaries. GPS data is provided in Figure I at
the end of this memorandum. Wetlands were categorized using currently adopted Federal Way.

3.0 Summary of Conflicting Findings between JCA and Otak
Otak was contracted by the City to perform a review of the JCA Reports and complete an
inspection of the Subject Property. According to the Memo prepared by Otak, a site inspection
was conducted August 30, 2006.Xtak staff conclusions differed From those of JCA regarding
wetland locations, findings of additional wetlands, stream locations and characteristics, and.
wetland test pit deterrninatiops., These differences in findings are summarized below:
1. Otak disagrees that JCA Test Pit 1 is upland (Otak Test Pit I), .
2. Otak identified one new wetland 150-200 feet SW of JCA.Test Pit 2 (Otak Test Pit 6);
3. Cit.ak disagrees that 1CA Test Pits 2 and 4 are wetland;
4. Otak disagrees with JCA at what point the drainage ditch south of the property meets the
definition of a stream; and
5. Otak identified an additional drainage or possible stream along the western property line
not identified in the Reports.
In addition to the general assessment of the site, each of these areas was thoroughly examined on
December 181h, 19`h. and 26th 2007 by Grette Associates Biologists in order to determine whether
or not each of the above conclusions is accurate. After completing our review of these specific
areas we have come to the following conclusions.
J. We agree with JCA that Test Vit i is upland;-,,* �
kWe agree with Otak that wetland is present at Othk Test Pit 6;
_,We agree. with Otak that JCA Test Pits 2 and 4 are upland.'
4. We disagree .with. both JCA and Otak.at which point the drainage ditch south of the
property meets the definition of a stream; and
5. We disagree with Otak that -a -possible stream is present on the western property line.
These conclusions are discussed in detail in the following section.
4,0 Findings — Site Assessment
Wetlands
According to the JCA Reports Test Pit 1 is upland and no wetlands are located on the Subject
Property. We agree with this statement. Our investigation of the area identified -as -Test Pit 1 to,
both the Reports and Memo concluded a preponderance of hydrophytic vegetation, 10YR 212
soils at 0-14" and IOYR 3/1 soils with faint mottles at 14-16", and no wetland hydrology or..
inland hydrology indicators present after very heavy rains. As this sample plot only satisfies '
cone of the criteria for wetland status, this sample plot was determined to be upland.
According to the Otak Memo, a wetland is present approximately 150-200' west of JCA Test Pit
2. (Otak Test Plot 6). We agree with Otak that this area is a wetland. _We.estimate-tile size of the:
wetland to be approi(4irtately 300 square feet. , Approximately 60 feet west of this location we
identified an additional wetland area associated with the JCA "western wetland". According to
GPS data, these wetlands are 145 feet and 190 feet from the SW property corner respectively.

Streams
JCA and Otak disagree at which point the drainage south of the Subject Property meets the
definition ofa regulated stream. According to FWCC Section 22-1 Definitions:
Stream means "a Course or route, formed by nature, including those which have
been modified by humans, and generally consisting of a channel with a bed, banks
or sides throughout substantially all its length, along which surface waters
naturally and normally flow in draining from higher to lower elevations. A stream
need not contain water year-round. in a developing setting, streams may run in
culverts or may be channeled in a concrete, rock or other artificial conveyance
system. This definition is not meant to include irrigation ditches, stormwater
facilities or other artificial watercourses unless they are used by resident or
anadromous salmonid fish, or the feature was constructed to convey natural
streams which existed prior to construction of the watercourse".
During our investigation we observed flowing water, signs of active scour and deposition at a
point 124' soUth the Subject Property. This point was located using GPS and is shown on Figure
1. at the end of this report. As this is the highest. point in the drainage containing both flowing
water and a defined channel, we determined that this is the point at which the drainage becomes
regulated as a stream (Photo 1).

This stream flows into the West Hylebos wetland complex and subsequently Hylebos Creek, a
salmon bearing stream. It is therefore considered a tributary to Hylebos Creek and is regulated
as a Major Stream. Major Streams require a 100' buffer (FWCC 22-1306). According to FWCC
Section 22-1 Definitions:
Major stream means "any stream, and the tributaries to any stream, which
contains or supports, or under normal circumstances contains or supports, resident
or migratory fish. if there exists a natural permanent blockage on the stream
course which precludes the upstream movement of anadromous salmonid fish,
then that portion of the stream which is downstream of the natural permanent
blockage shall be regulated as a major stream".
The Otak Memo identifies a "ditch-swale-stream system" along the western property boundary
not identified in the ICA Reports. We observed a linear depression along the western property
boundary. After heavy rains, no signs of flowing water, saturated soils, defined channels, or
observations of sediment scour and deposition was observed in this area (Photo 2). This area
therefore does not meet the criteria for a regulated stream or wetland.

5.0 Findings — Report Review
According to FWCC 22-1356 a wetland report shall be prepared by a City approved qualified
professional and contain the following information concerning wetlands identified on or within
200 feet of the Subject Property:
(1) An evaluation of whether the area in question is a regulated wetland, based on
the definition of "regulated wetland" in FWCC 22-1.
(2) An overview of the methodology used to conduct the study.
(3) A description of the wetland and plant communities found therein, a map
delineating the edge of the wetland and location of plant communities, and a
detailed description of the method used to identify the wetland edge.
(4) The wetland classification, according to the U.S. Fish and Wildlife Service
"Classification of Wetlands and Deep Water Habitats in the U.S."
(5) A list of observed plant and wildlife species, using both scientific and
common names, and a description of their relative abundance.
(6) A list of potential plant or animal species based on signs or other observation.
(7) An evaluation and assessment of the existing or potential functions and values
of the wetland based on the following factors: surface water control; wildlife
habitat; pollution and erosion control; groundwater exchange; open space and
recreation; and educational and cultural opportunities.
We find that the JCA Reports accurately describe background information and methods used to
make wetland determinations. However, the JCA Reports fail to provide all the required
information listed in FWCC 22-1356 numbers 3 through 7 above. in addition, although the
"Field Note Sketch Maps" identify general wetland locations and test pits, they do not clearly
show wetland boundaries. In order to meet the FWCC 22-1356 number 3 requirements, JCA
needs to delineate the wetland boundaries within 200 feet of the Subject Property and prepare a
professionally drawn, legible, scaled delineation map, clearly showing property boundaries and
the location, shape and extent of the off -site wetlands, streams, and their associated buffers
within 200' of the Subject Property. Furthermore, JCA will need to prepare an addendum to
their reports that provides the additional information required by numbers 4 through 7 of FWCC
22-1356,

Wetland Rstin
The off -site area south of the Subject Property slopes down to the West H_yiebas Wetland
Complex This area contains several slope wetlands that are maintained by subsurface
groundwater moving down slope. The topography of the slope is hummocky and many small
wetlands have formed in shallow depressions created by the hummocks. As such, the off -site
wetlands 145' and 190' SW of the Subject Property form a mosaic with additional off -site
wetlands further down slope that are functionally connected to the West H ly ebos Wetland
Cormplex. The West Hplebos Wetlandr are_ regulated as ory-L MLct1A►*s ac ;l,ey_so

Subject: Wetland Verification for the ,Ias h+ke_W Site Q, Federal Wa , located at
803 S. 348th Street, Tax Parcel No. 2021049087, situated in the SE %4 of Section 20-
T21N-R4E, W.M., Federal Way, WA
To Whom It May Concern:
In response to your request, John Comis Associates (JCA) conducted an onsite
investigation on February 1, 2005 to verify the presence or absence of regulated wetlands
that may be within the subject property or on adjacent offsite properties (see enclosed
maps for site specific information including locations and test results).
The field investigation was limited to a determination of "regulated wetlands" on the site,
or within 150 feet z of the site boundary. The identification of wetlands was based on the
current 1997 Washin ton State Wetlands Identification and Delineation Manual. This
methodology was consistent with methods used by the 1987 Corps gfngineers Wetland
Delineation Manual. The identification of "regulated wetlands" was also made in
accordance with the City of Federal Way Critical Areas Regulations.
This work included a routine onsite determination for any wetlands that may be found
within or adjacent to this site. The Field Note Sketch Map (FNSM) by JCA shows the
locations of sample test plots that were dug by hand to analyze the vegetation, soils and
hydrology conditions that exist at these representative locations. We also examined the
adjacent offsite area to the west within the grove of cottonwood trees to determine if any
wetland(s) may exist within that area with buffers that may extend into the subject site.
The 150-foot distance is the standard buffer width for the highest rated Class 1 wetland. This represents a reasonable
distance from which a "regulated activity" should not impact a "regulated wetland" (per City of Federal Way Critical Areas
Regulations (definitions, exemptions and buffers).

The sample test plots are marked and flagged by JCA. These locations are numbered as
shown on the FNSM and flagged with blue and green colored ribbons tied to wooden
stakes or vegetation.
The wetland verification included evaluation of possible wetlands that may be present
within or along the western site boundary as indicated by wetland field indicators
including some hydrophytic vegetation, marginal hydric soils and possible saturation or
inundation. The evaluation of possible wetlands is also based on current City of Federal
Way critical area regulations.
The scope of work included review of available map information showing onsite and
offsite conditions within the subject property such as the soils survey map (Figure 3). We
also examined the adjacent depression along the southwestern property line. We
examined conditions at this time within possible wetland area as indicated on the
County's "Wetland Indicator Mapping" (Figure 2). We examined offsite areas adjacent
to the west side of the site within the forested cottonwood area to determine if sufficient
field indicators are present to meet all 3-parameters for a positive wetland determination:
hydrophytic vegetation, hydric soils and hydrology (inundation and/or saturation).
Findings
NO onsite or adjacent offsite wetlands are found within the subject property.
• The "non -wetland" determination is based on a lack of hydrology found within 3 test
holes that we dug in the lower parts of the onsite and offsite depression (see Field
Note Sketch Map, Figure 4, by JCA dated 2/l/05 for locations and notes).
• Test plot #2 (TP2) is dug offsite in what appears to be the lowest part of the natural
topographic depression (see Field Notes, Figure 4a and 4b, by JCA dated 2/l/05).
• The soils in the lower parts of the depression (the adjacent offsite area) appear to be a
"Everett-AIderwood" series gravelly sandy loam (EwC) and not the "Seattle Muck"
as indicated on the Soils Survey Map as shown by the Soils Survey Map (Figure 3).
• The surrounding area, including the onsite portion of the lobe of possible wetland at
the southwestern part of the site, appears to have a soil type that matches the
description of the "Everett-Alderwood" series (see field note data on Figure 4b).
• Potential wetland areas along the western boundary of the site were examined by JCA
at this time and found to all be non -wetland (see our Field Note Sketch Map, Figure
4a, for locations and Figure 4b for test plot results for TP1, TP2 and TP3).
Please note that this work did not include a detailed land survey. Locations are
approximate (but accurate) based on our hip -chain measurements from the front of the
property. If additional work is requested by the Client or required for regulatory agency
review(s), this can be prepared only after additional work is authorized by the client.

Joseph Pircey Property Sensitive Areas Assessment
and Review of Wedand Verification Reports
by John Comis Associates
30879H
As requested by the City of federal Way, on August 30, 2006 Suzanne Bagshaw and Stephanie
Smith conducted a field visit to the Pircey property located at 803 South 348`b Street in Federal Way,
Washington. The purpose of the site visit was to determine whether jurisdictional wetlands or
streams are located within approximately 300 feet of the subject property, and to evaluate the
wetland verification reports by John Cornis Associates OCA) listed below for consistency with
Federal Way City Code. 'Towards that end, we reviewed the following documents:
• Wetland Verification for the Joseph Pircey Site @ federal Way by John G. Comis of John
Corms Associates, dated February 21, 2005; stamped Received by the City of Federal Way
Building Dept. June 6, 2006;

As required by FWCC 22-1 (Wetland Definition), John Comis Associates QCA) followed
methodology specified in the March 1997 Washington State Vetlands Identification and Delineation

• More information will be required regarding the sizes, ratings, and locations relative to the
subject property of the wetland associated with the stream and the western wetland south of the
old stormwater pond.
• We located a wetland that was not identified in the JCA reports. This additional wetland is
located approximately 150-200 feet southwest of the subject property (Otak TP 6). More
information regarding the size and rating of this wetland and its location relative to the subject
property will be required.
• It appears that the section of the drainage course that satisfies FWCC criteria for a regulated
stream begins north (upstream) of location identified in the JCA reports - at approximately 70
feet southwest of the subject parcel instead of 230 feet. We also located a drainage ditch along
the western boundary of the subject property that was not identified in the JCA reports. The
ditch may be connected to the stream, and so it may also be jurisdictional. In order to determine
the Went and location of the jurisdictional stream, more information will be required regarding
the connectivity of surface flow through the ditch-swale-stream system during the rainy season.
With the exception of the old stormwater pond, wetlands located west or south of the subject
parcel axe likely to be rated as Category I either because they are part of the large Category I
wetland located in West Hylebos Wetlands State Park (Federal Way Wetland Inventory # 20-21-
4-121), or because they arc hydrologically and/or functionally associated with that wetland
(MCC 22-1). Category I Wetlands have a 200-foot buffer [FWCC 22-1357(b)(1)].
Sny regulated stream located west or south of the subject parcel is likely to be rated as a Major
Stream because it is likely to be a tributary to W iylebos Creek which is salmon -bearing (FWCC
22-1). Major streams have a 100-foot buffer [FWCC 22-1306(a)(1)].
Results of the Site Visit and Review of the JCA Wetland and Stream Verification Reports
The Pircey property is located at 803 South 348ffi Street. Two houses and associated small
outbuildings are located on site. West Tlylebos Wetlands State Park is located diagonally southwest
from the southwest property corner. John Comis Associates performed two visits to the Pircey
property on February 1, 2005 and January 14, 2006. They followed methodology specified in the
March 1997 f�/ashington State Wfetlands Identfication and Delineation Manual (Department of Ecology
publication No. 96-94) to identify wetlands on the subject property and in areas adjacent to the
south and west sides of the subject property. JCA used a hip -chain to measure distances to their test
pits, therefore those distances are only approximations. Because the string lines are laid down as one
walks over rough ground, scrambles over fallen trees, through dense vegetation, and around
impenetrable vegetation, the lines arc not straight. As a result, actual distances are likely to be shorter
than those measured with a hip -chain. The longer the measured distance, the greater the inaccuracy
of the hip -chain measurement.
The two JCA wetland reports include data sheets for eight test pits (labeled JCA TP 1— 8 and a
Field Note Sketch Map which shows the approximate locations of their test pits (see attached JCA
Figure 6). During our site visit on August 30, 2006, we located all of the JCA test pit flags except

JCA TP 3, but we were able to identify its approximate location. We dug test pits at all of those
locations and at other additional locations. Copies of our data sheets (Otak TP1— 11-38) are included
at the end of this memorandum.
The JCA reports conclude that there are no wetlands located on the subject property, within 220
feet west of the subject parcel, or within 300 feet southwest of the subject pareeL We disagree with
these conclusions. We identified a non -jurisdictional wetland onsite, and an additional wetland
located approximately 150-200 feet west southwest of the subject property (discussed in more detail
below). The JCA reports identify two wetland areas approximately 220 feet west of the subject
parcel, one of which appears to be an old stormwater detention pond located just south of S. 3481"
Street. The second wetland to the west is located south of the stormwater pond. The JCA reports
also identify a wetland associated with the drainage course located approximately 300 feet southwest
of the subject property. We agree with the characterizations of those wetlands; however more
precise information regarding their locations relative to the subject property is required (see below).
The JCA reports conclude that the drainage course which flows from north to south becomes a
regulated stream at a point approximately 230 feet southwest of the subject parcel. We disagree with
that conclusion. We found that the drainage course satisfies the criteria for a jurisdictional stream
closer to the subject property —possibly as close as 70 feet (see below). We located a drainage ditch
adjacent to the west side of the subject property that is not identified in the JCA reports. It is
possible that the ditch might satisfy'the criteria for a jurisdictional stream (see below).
Wetlands
The JCA site visits were performed during the winter (February 2005 and January 2006). t\lthough
winter is a good season for observing hydrology, most herbaceous and deciduous species are
dormant at that time. As a result, many herbaceous species were not present in the JCA sample
plots. In addition, some indicators, such as oxidized rhizospheres, are absent when roots are not
actively growing Seasonal differences account for many of the specific c differences between the JCA
data sheets and the Otak data sheets.
JCA TP 1 is the only test pit located on the subject property that is documented in the JCA reports.
It is located in a low spot in the lawn near the southwest corner of the property (see attached copy
of JCA Field Note Sketch Map Figure 6). We disagree with the JCA conclusion that JCA TP 1 is
upland. We agree that the sample area is dominated by hydrophytic vegetation, but we also found
distinct mottles in a 2.5YR 6/2 sandy clay from 5-12 inches below the surface, and oxidized root
channels above 12 inches (see the attached data sheet for Otak TP 1). As a result, Otak TP 1
satisfies all three criteria necessary for wetland determination. However, the area appears to be
isolated and significantly smaller than 2,500 square feet., so the wetland is probably not jurisdictional
under Federal Way City Code (FWCC 22-1).

We agree with most of the JCA conclusions for the offsite test pits. We agree that JCA TP 3, 5, 6, 7,
and 8 are upland plots because they do not satisfy all three criteria (hydrophytic vegetation, hydric
soil, and hydrology) required for wetland determination (see data sheets for Otnk TP 3 — TP 5).
Although JCATP 7 and 8 are not wetland plots, they are associated with a seasonal stream (see
stream section below).
The JCA reports identified JCA TP 2 and 4 as upland plots in 2005, but identified them as very
small isolated wetlands in 2006. Based on the dominance of vine maple (Ater cininatum, FA.G) and
other non-hydrophytic species, we determined that both of these sample plots are upland areas (see
data sheets for Otak TP 2 and 8). JCA TP 2 appears to be associated with a seasonal stream, and
JCA TP 4 appears to be associated with a ditch/drainage swale system which may be a jurisdictional
stream (see stream section below).
We agree with the JCA conclusion that the old stormwater pond located west of the subject
property (south of S. 348``' Street) is a wetland (see data sheet for Otak TP 7). We also located a
wetland south of the storm pond. This forested wetland is dominated by alders (Alnus rubra, FAC),
with salmonberry (13ubur speclabilis, FAC+) and slough sedge (Cams obnupta, OBL) in the understoxy.
This wetland is probably the western wetland identified in the JCA reports. We also located the
stream associated wetland that is identified in the )CA reports south of JCA TP 8 (south southwest
of the subject property). The wetlands may or may not be located within 200 feet of the subject
property --more accurate information is necessary. Although we did not delineate them, the
wetlands, other than the stormwater pond, are likely to be hydrologically connected to the Category
1 wetland to the south. if so, they would also be rated as Category I. TWCC regLires 200-16ot
buffers for Category I wetlands.
Additional Wetland
We located an additional wetland west southwest of JCA TP 2 (see data sheet for Otak'1'P 6). This
wetland may be within 200 feet of the subject property. The scrub -shrub wetland is dominated by
vine maple and salmonberry, with skunk cabbage in the understory. Even after an extremely dry
summer, the 10YR 3/1 clay was so moist that it was nearly saturated at two inches below the
surface. The wetland is located west of the ditch -Swale -stream system (see stream section below) in a
southward sloping, wide swale-like area. Although we did not delineate the wetland, it is likely to be
hydrologically connected to the Categoxy I wetland to the south. If so, the additional wetland would
also berated Category 1. ltiurther investigation will be necessary to determine the size and rating of
this additional wetland and its location relative to the subject property.
Stream and Drainage Ditch Characterization
The JCA reports identify a regulated stream which Flows from north northeast to south southwest
beginning approximately 230 feet southwest of the subject property, in the vicinity of JCA TP 8

(Otak TP 4). Although we agree that there is a seasonal regulated stream, we conclude that the point
at which the drainage course satisfies FWCC criteria for a regulated stream (FWCC 22-1) begins
further upstream, closer to the subject property. 'there is a clearly defined channel at JCA TP 7
(Otak TP 3) approximately 175 feet southwest of the subject property. Although somewhat less
clearly defined, there appears to be a channel close to JCA TP 2 (Otak TP 2), approximately 70 feet
southwest of the subject property. FWCC requires 100-foot buffers for Major Streams. North of
JCA TP 2 there is a broad, vine maple dominated, swale-like depression. This drainage
swale/depression runs close to the western boundary of the subject property, and it appears to be
the upstream continuation of the stream channel —we observed some evidence of flow in it.
We located a drainage ditch along the central portion of the western side of the subject property that
is not identified in the JCA reports. The ditch takes a sharp turn away from the subject property in
the vicinity of JCA TP 4 (Otak TP 8). Shortly thereafter, the ditch becomes less defined and it
outlets into the drainage swale/depression that extends southward (downstream) to JCA TP 2. If
surface flow from the drainage ditch continues through the swale/depression into the defined
stream channel, -it is possible that the drainage ditch may be a jurisdictional stream. As previously
mentioned, FWCC requires 100-foot buffers for Major Streams.
The only way to make an accurate determination as to the extent and location of the jurisdictional
stream is to re-examine the ditch-swale-stream system during the rainy season to assess surface flow
and connectivity.
Additional Information Required
Additional information is required regarding the estimated size and subsequent ratings and
buffers, and locations relative to the subject property of the wetland associated with the stream
(south of JCA TP 8) and the wetland west of the site (south of the old storm -water pond).
Distances from the subject property to the wetlands and streams offsite should be provided by
an actual survey, not estimated by hip -chain in order to more accurately determine the extent of
required buffers relative to the property lines.
Additional field information is required regarding the size and rating of the additional wetland
that we observed (Otak TP 6) and its location relative to the subject property.
In order to determine the extent and location of the jurisdictional stream, it will be necessary to
field confirm conditions regarding the connectivity of surface flow through the ditch-swale-
stream system when soils are completely saturated and surface flows most likely to be present.

Graffiti complaint numerous signs tagged on telephone poles on north side of street on Dash Point Road just west of Pacific
Highway, and stretching all the way to at least 9th Ave. S. They are yellow and black warning signs posted on each telephone
pole as the road curves around. The complainant is Mary Jane Marshall @ 253-839-4684. Let me know if that is enough info.
Thanks, Becky
