RE: File#08-103012-00-AD; GUMIRAN WETLAND DETERMINATION
35215 1st Avenue South,Federal Way
Dear Mr. Dickinson:
On June 20, 2008,the Department of Community Development Services received your request for a wetland
determination with regard to an on-site wetland located on the above-referenced property. Your request
included a wetland evaluation performed by Alder NW dated June 4, 2008.The Alder NW evaluation
produced findings that the on-site wetland located at 35215 1s`Avenue South should be classified as
Category II,not Category I as classified in the City's critical areas inventory. As part of the wetland
determination,the City has retained ESA Adolfson to conduct a peer review of the Alder NW report.
FINDINGS •
Review of the Alder NW evaluation and subsequent site visit conducted by Adolfson biologists Sara Noland
and Lara Thoreson concludes the on-site wetland is a Category I wetland and is classified correctly in the
City's critical areas inventory. As referenced in the enclosed technical memo,these findings include:
o The on-site wetland is hydrologically connected via major stream to the West Hylebos Wetland Park
which provides significant habitat, exceptional local significance, and a unique educational site
thereby satisfying Federal Way City Code 22-1357(a)(1)(b)criteria for Category I wetlands.
o Opportunity for water to flow between the on-site and off-site wetlands via culvert under 1st Avenue
South,thereby meeting the criterion that the wetlands on either side should not be considered
separate.
CLOSING
As the Adolfson findings confirm the City's Category I designation, applicable comments provided by the
City's Development Review Committee meeting with the applicant May 8, 2008, shall apply. If you have any
questions regarding this letter or your development project,please contact me at 253-835-2638 or

date September 26,2008
to Matthew Herrera,City of Federal Way
from Sara Noland
subject Gumarin Short Subdivision(File#08-101306-SU)
At the request of the City of Federal Way,ESA Adolfson has reviewed the wetland evaluation letter report
prepared by Alder NW for the Gumarin property(letter dated June 4,2008;received by ESA Adolfson from the
City on August 18,2008). The property is a 2.7-acre site located at 35215 First Avenue South in Federal Way,
Washington.
ESA Adolfson also reviewed the City's 2005 stream classification and critical areas map,as well as information
from the City's 1998 Wetland Inventory relevant to the Gumarin parcel. The purpose of this review was to
evaluate the submitted report per the requirements of Federal Way City Code(FWCC)Chapter 22 pertaining to
wetlands and streams.
Document Review
The Alder NW report describes the site as containing an existing single-family residence,garage,and sheds with
surrounding lawn,landscaping,and mixed forest. The site is described as sloping down toward the east and
northwest. Alder NW identified a stream(described as a branch of Hylebos Creek)crossing through a triangular
shaped wetland in the northeast corner of the site. The wetland was delineated by Alder NW in January 2008.
The report states that Alder NW revisited the wetland in May 2008 to review drainage patterns in the wetland.
Alder NW states that the on-site stream enters the north side of the property via a culvert underneath an access
driveway to apartments located northwest of the site. The stream runs through the on-site wetland and exits the
site via a second culvert under First Avenue South. The report describes that Hylebos Creek upstream and
downstream of the site has been mapped as a"major creek"by the City of Federal Way. The City's 2005 stream
classification map shows the on-site stream as a"major creek."
The Alder NW report concludes that the on-site wetland should be considered a Category II wetland because it is
larger than 2,500 square feet and contiguous with a water body that supports fish. The report states that the on-
site wetland should be considered separate from off-site wetland areas to the north and east for purposes of
assigning wetland classifications and buffer requirements. They conclude that both the stream and the wetland
require a buffer width of 100 feet under City code.
The City of Federal Way Wetland Inventory(1998)and critical areas map(2005)indicate that the wetland on the
Gumarin parcel is part of a large wetland system located along West Hylebos Creek. The central portion of this
wetland is located within West Hylebos Wetlands Park,east of First Avenue South. The map shows the
northwestern edge of this wetland extending onto the Gumarin parcel. While the Alder NW report describes the
Matthew Herrera\Gumarin Wetland Review

on-site wetland as Category II,the City of Federal Way Wetland Inventory identified this wetland system as a
Category I wetland. This classification appears to have been based on the presence of three or more wetland
classes,one of which is open water(FWCC 22-1357).
Site Visit
ESA Adolfson biologists Sara Noland and Lara Thoreson visited the site on August 28,2008. Site conditions
were generally consistent with the Alder NW report description. Wetland boundary flags were still present on-
site,and we agreed with the wetland boundary delineation. The on-site wetland contains a single vegetation
community type(forested).
Surface water three to six inches deep was flowing to the southeast within the on-site stream channel(Photo 1).
No ponding was present at the upstream culvert(under the access road to the off-site apartments). This portion of
the stream channel had a noticeable slope downward to the southeast.
Within the central portion of the on-site wetland,portions of the stream channel were incised. A pool
approximately three feet wide containing surface water approximately seven inches deep was present where the
stream entered the culvert under First Avenue South(Photo 2). A similar pool was present at the off-site end of
this culvert,east of First Avenue South. Both ends of this culvert were underwater and the culvert appeared to be
relatively level. Very little flow was evident in the ponded areas.
Review Comments
We concur with the Alder NW report that the on-site stream is a"major creek,"which requires a standard buffer
width of 100 feet(FWCC 22-1306). The stream buffer falls within the buffer for the surrounding wetland.
We disagree with the conclusion of the Alder NW report regarding the classification of the on-site wetland.
Based on the submitted wetland report and our site observations,we recommend that the on-site wetland should
be considered part of the larger Category I wetland system identified in the City's wetland inventory. The on-site
wetland would therefore require a 200-foot buffer(FWCC 22-1357). We do not believe that the available
information supports giving the on-site portion of this wetland system a lower rating(Category II)or smaller
buffer(100 feet)than the rest of the wetland system. The rationale for this conclusion is based on the following:
First,one of the City's criteria for defining a wetland as Category I is that it contains"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"(FWCC 22-1357(a)). The on-site wetland is hydrologically
connected via a major creek to the West Hylebos Creek wetlands. These wetlands and this stream system provide
significant habitat and have exceptional local significance for the City.
Second,Alder NW refers to the Department of Ecology's Western Washington Wetland Rating System Manual
for guidance on addressing wetlands bisected by human-made features such as roads. While the City does not use
this rating system in assigning wetland classifications,we agree that it is appropriate guidance in this situation.
Page 19 of the Manual(attached)specifically addresses when a wetland that is divided by a road should or should
not be divided into separate"units"(i.e.,separate wetlands).
Based on our site observations,there appears to be a level surface water connection between the wetland areas on
either side of First Avenue South. Both sides of the culvert on either side of First Avenue South were underwater
during our site visit in August 2008. The Alder NW report states that there is a difference of only 1.2 inches

elevation between the ends of the culvert based on survey data. There was very little flow evident in the ponded
areas on either side of the culvert. This situation provides the opportunity for water to flow between the on-site
and off-site portions of the wetland. This meets Ecology's criteria for when wetlands on either side of a roadway
should not be considered separate.
In addition,the Alder NW report argues that,while the culvert under First Avenue South is nearly level based on
survey data,there is an elevation difference of a foot or more between the"body of the wetlands"on either side of
the roadway. However,this statement is not supported by surveyed elevation data within the wetlands.
Recommendations
Based on the above review,ESA Adolfson recommends that the wetland on the Gumarin property should be
considered part of the larger Category I wetland system mapped by the City. The on-site wetland would therefore
require a 200-foot buffer width.
Limitations
Within the limitations of schedule,budget,and scope-of-work,we warrant that this study was conducted in
accordance with generally accepted environmental science practices,including the technical guidelines and
criteria in effect at the time this study was performed. The results and conclusions of this report represent the
authors'best professional judgment,based upon information provided by the project proponent in addition to that
obtained during the course of this study.No other warranty,expressed or implied,is made.
Thank you for the opportunity to provide this review. If you have any questions,please contact me at

usually assume that the water depth in this area of open water is shallower than the depth
in the area of the plants further offshore. In this situation the open water is considered a
part of one wetland that encompasses both the rooted submerged plants offshore and the
shore-side plants. The absence of plants in the area of open water may only be
temporary,or the submerged plants are present but not visible because they do not grow
to the surface. The vegetation may also be absent due to wave action,physical removal,
or herbicide applications.
Wetlands Bisected by Human-Made Features
When a wetland is divided by a human-made feature,such as a road embankment,the
wetland should not be divided into different units if there is a level surface-water
connection between the two parts of the wetland. Water should be able to flow equally
well between the two areas. For example,if there is a wetland on either side or a road
with a culvert connecting the two,and both sides of the culvert are partially or completely
underwater for most of the year,the wetland should be rated as one. Make the down
gradient wetland a separate unit,however,if the bottom of the culvert is above the high
water marks in the receiving wetland,or the high-water marks on either side differ by
more than 6 inches in elevation.
Cases When a Wetland Should Not be Divided
Differences in land uses within a wetland should not be used to define units,unless they
coincide with the circumstances described above. For example,if half a wetland has �_ Comment[6]: Many functions that a
been recently cleared for farming and the other half left intact,the entire area functions wetland unit performs are independent of

Dear Ms: Kondelis
As requested, I completed a wetland evaluation study for the property located on the northwest corner of the intersection
of First Avenue South and SW 353`d Street Court in the City of Federal Way,Washington. The purpose of this work was
to identify the limits of the wetland area on the property.
The scope of work included a site visit on January 30, 2008, at which time we completed our site evaluation and flagged
the limits of the wetland area on the property. We made a second visit to the site on May 25,to review drainage patterns
within and through the wetland.
PROCEDURES
For the purpose of this study, we used the wetland definition adopted by the Environmental Protection Agency(EPA)and
the Army Corps of Engineers (COE) for administering Section 404 of the Clean Water Act. According to this definition,
wetlands are:
Those areas that are inundated or saturated by surface water 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. (33 CFR 323)
In accordance with this definition, a given area is designated as jurisdictional wetland if the hydrology results in inundated
or saturated soils during the growing season, hydric soils are present, and the dominant vegetation is hydrophytic.
Delineation procedures are based on diagnostic environmental indicators of wetland vegetation, wetland soils, and
wetland hydrology. By definition, an area is designated as wetland when there are positive indicators for all three
parameters.
A listing of plant species has been developed for use in the methodology for delineating wetland areas. This listing
assigns plant species to one of five indicator status categories ranging from Obligate wetland species, which almost
always occur in wetlands, to Upland species, which rarely occur in wetlands. Under normal conditions, hydrophytic

vegetation is determined to be present if more than 50 percent of the dominant species are in the Obligate (OBL),
Facultative Wetland(FACW),or Facultative(FAC)indicator categories.
Diagnostic indicators of hydric soils are related to soil saturation, which leads to anaerobic conditions in the soil. Under
these conditions, decomposition of organic material is inhibited and soil minerals are reduced, creating characteristic soil
colors that can be quantified by comparison with Munsell Soil Color Charts. A chroma of one or less in unmottled soils
or a chroma of two or less in mottled soils generally indicates a hydric soil. In addition, soils that are saturated during the
growing season satisfy a criterion for hydric soils. We used a hand auger to collect soil samples from a depth of 8 to 16
inches.
Wetland hydrology is defined as inundated or saturated soil conditions for at least 14 consecutive days during the growing
season. If no water is present at the time of evaluation, other indicators may include topographic low points or channels,
flood debris, complete absence of vegetation, or presence of hydric soils.
SITE CONDITIONS/WETLAND
The subject property is rectangular shaped parcel of approximately 2.7 acres. The location of the property is illustrated on
the Vicinity Map (Figure 1). It is bounded on the east by 1st Avenue South, and on the north by a paved road providing
access to an apartment complex off the northwest corner of the property. A gravel surfaced driveway along the SW 353rd
Street right-of-way forms the south property line. The two properties to the west are currently occupied by existing
single-family residences.
There is an existing single-family residence on the subject property along with a garage and several smaller sheds. Except
for the area immediately surrounding the home, which is occupied by lawn and landscaping, the property is largely
undeveloped and is occupied by mixed forest.
Topographically, the property generally slopes down from approximately elev. 246 along the west property line to ward
the east and northwest. The low point on the property is on the northeast corner,where a branch of Hylebos Creek crosses
the northeast corner, and enters a 48"diameter culvert under 15t Avenue South.
We have identified the limits of a roughly triangular shaped wetland on the northeast corner of the property as shown on
site maps prepared by CramerNW and on the attached Site Map (Figure 2). The northern and eastern limits of the wetland
are generally defined by the road berms for 1'Avenue South and the roadway along the north property line. It appears
that there had been some grading on the property in the past to create a larger flat area around the existing house. The
southwest limits of the wetland are defined in part along the limits of the past grading.
Vegetation within the wetland is dominated by red alder (Alnus rubra) trees. Understory shrub species include
salmonberry (Rubus spectabilis), hardhack spirea (Spiraea douglasii), Himalayan blackberry (Rubus discolor) and red
osier dogwood(Cornus stolonifera).
A branch of Hylebos Creek flows through the site wetland. The creek enters the north property line through a 48"
diameter culvert, and flows across the northeast corner where it enters a 48: diameter culvert under 1S` Avenue South.
Upstream and downstream or the property, Hylebos Creek has been mapped as major creek under City of Federal Way
stream criteria.
There are forested wetland areas to the north and east of the subject property. The site wetland is separated from the off-
site wetland to the north by the approximately 50ft wide road berm for the roadway accessing the apartment complex off
Project No. 42508
Page No. 2

the northwest corner of the property. It is separated form the wetland off the property to the east by the approximately
60ft berm for 1' Avenue South.
The Washington State Wetland Rating System for Western Washington, Washington State Department of Ecology
publication number 04-06-025 provides guidance for defining the extent of wetlands where there are a wetland is divided
by a human-made feature, such as a road embankment. Wetlands divided by roadways are treated as separate wetlands
where there is one way flow through culverts connecting the two sides of the embankment. If the wetland on either side
of the embankment are to be considered as one unit, water should be able to flow equally well between the two areas on
either side of the road embankment.
There is a drop of almost two feet between the upstream and downstream elevations in the culvert entering the north side
of the wetland. The site wetland should be considered as a separate unit from the wetland to the north.
At the east end of the wetland there is less difference in the invert elevations for the upstream and downstream ends of the
culvert in 1'Avenue South. At the time of observations in January and in late May,there was water movement from west
to east through the culvert. Survey date shows that the difference in the culvert invert elevations across the road
embankment is approximately 1.2 inch. Them is li le_elexa;,i,s chars eawithin the stream ghannejacross .lies way,but
there is a foot or more elevation difference between the surface elevations in the body of the wetlands on either side of the
roadway. High water marks on the west side of the road way are contained within the stream channel and there is no back
up of water into the body of the wetland on either side of the stream channel.
It is our interpretation that the site wetland should be designated a separate unit from the wetlands to the north and east.
It is our interpretation of the City of Federal Way Wetland rating system, that the site wetland meets the criteria for
designation as a City of Federal Way Category II Wetland. It satisfies the criteria for this category because it is greater
than 2,500sq.ft in size and is contiguous with a water body which supports a fish population.
In accordance with City of Federal Way regulations, a buffer of 100ft is assigned to Category II wetlands. The buffer for
the branch of Hylebos Creek passing through the wetland is 100ft. As such the stream buffer does not extend beyond the
100ft wetland buffer.
We trust the information presented is sufficient for your current needs. If you have any questions or require
additional information, please call
Sincerely yours,
