H 1.3 Richness of Plant Species (see p. 75):
Count the number of plant species in the wetland that cover at least 10 ft2 (different patches of the same
species can be combined to meet the size threshold)
You do not have to name the species. Do not include Eurasian Milfoil, reed canarygrass,purple
loosestrife, Canadian Thistle. If you counted: > 19 species points=2

Undercut banks are present for at least 6.6 ft. (2m)and/or overhanging vegetation extends at least 3.3
ft. (1m)over a stream(or ditch)in, or contiguous with the unit, for at least 33 ft. (10m)
❑ Stable steep banks of fine material that might be used by beaver or muskrat for denning
(>30 degree slope)OR signs of recent beaver activity are present (cut shrubs or trees that have
not yet turned grey/brown)
® At least 1/4 acre of thin-stemmed persistent vegetation or woody branches are present in areas that
are permanently or seasonally inundated (structures for egg-laying by amphibians)
® Invasive plants cover less than 25%of the wetland area in each stratum of plants

Old Growth Forest El Flats ❑
Coastal Lagoon ❑ Freshwater Tidal ❑
Interdunal ❑ ❑
None of the above ❑ Check if unit has multiple ❑
HGM classes present
Does the wetland being rated meet any of the criteria below? If you answer YES to any of the questions below you will
need to protect the wetland according to the regulations regarding the special characteristics found in the wetland.
Check List for Wetlands that Need Additional Protection YES NO
(in addition to the protection recommended for its category)
SP1. Has the wetland unit been documented as a habitat for any Federally listed Threatened or
Endangered animal or plant species (T/E species)? Cl ❑
For the purposes of this rating system, "documented" means the wetland is on the appropriate
state or federal database.
SP2. Has the wetland unit been documented as habitat for any State listed Threatened or
Endangered animal species? For the purposes of this rating system, "documented" means the ❑
wetland is on the appropriate state database. Note: Wetlands with State listed plant species
are categorized as Category 1 Natural Heritage Wetlands (see p. 19 of data form).
SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? ❑
SP4. Does the wetland unit have a local significance in addition to its functions? For example, the
wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or ❑
in a local management plan as having special significance.
To complete the next part of the data sheet you will need to determine the Hvdrogeomorphic Class of tile wetland being rated.
The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions need: . er how well the wetland
functions. The Hydrogeomorphic Class of awetland can be determined using the key below. See p.24 for more detailed'∎ _ .,L=� class' ',e.. ds.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated,you probably have a unit with
multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8.
1. Are the water levels in the entire unit usually controlled by tides(i.e. except during floods)?
®NO—go to 2 ❑ YES—the wetland class is Tidal Fringe
If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt(parts per thousand)?
❑YES—Freshwater Tidal Fringe ❑ NO—Saltwater Tidal Fringe(Estuarine)
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it
is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt
Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions,and
this separation is being kept in this revision. To maintain consistency between editions,the term"Estuarine"wetland is kept. Please
note,however,that the characteristics that define Category I and II estuarine wetlands have changed(seep. ).
2. The entire wetland unit is flat and precipitation is only source(>90%)of water to it. Groundwater and surface water
runoff are NOT sources of water to the unit.
®NO—go to 3 ❑YES—The wetland class is Flats
If your wetland can be classified as a"Flats"wetland, use the form for Depressional wetlands.
3. Does the entire wetland meet both of the following criteria?
❑ The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on
the surface)where at least 20 acres (8ha) in size;
❑At least 30%of the open water area is deeper than 6.6 (2 m)?
®NO—go to 4 ❑YES—The wetland class is Lake-fringe(Lacustrine Fringe)
4. Does the entire wetland meet all of the following criteria?
® The wetland is on a slope (slope can be very gradual).
® The water flows through the wetland in one direction(unidirectional) and usually comes from seeps. It may flow
subsurface, as sheetflow, or in a swale without distinct banks.
® The water leaves the wetland without being impounded?
NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and
shallow depressions or behind hummocks (depressions are usually<3 ft diameter and less than 1 foot deep).
❑NO—go to 5 ® YES—The wetland class is Slope
5. Does the entire wetland meet all of the following criteria?
❑ The unit is in a valley or stream channel where it gets inundated by overbank flooding from that stream or river.
❑ The overbank flooding occurs at least once every two years.
NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding..
®NO—go to 6 ❑ YES—The wetland class is Riverine
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of
the year. This means that any outlet, if present is higher than the interior of the wetland.
®NO—go to 7 ❑YES—The wetland class is Depressional
7. Is the entire wetland located in a very flat area with no obvious depression and no overbank flooding. The unit does not
pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The
wetland may be ditched,but has no obvious natural outlet.
®No—go to 8 ❑ YES—The wetland class is Depressional
8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example,seeps at the base of a
slope may grade into a riverine floodplain,or a small 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 10%of the unit,classify the wetland using the class that represents more than 90%of the total area.
HGM Classes within the wetland unit being rated ,AGM,Class to Use in Rating
Slope +Riverine Riverine
Slope+Depressional Depressional
Slope+Lake-fringe Lake-fringe
Depressional+Riverine along stream within boundary Depressional
Depressional+Lake-fringe Depressional
Salt Water Tidal Fringe and any other class of Treat as ESTUARINE under wetlands with special
freshwater wetland characteristics
If you are unable still to determine which of the above criteria apply to your wetland, or you ha e qN thvira AVM classes
within a wetland boundary, classify the wetland as Depressional for the rating.

SP 1. Has the wetland unit been documented as a habitat for any Federally listed Threatened or
Endangered animal or plant species (T/E species)? El
For the purposes of this rating system, "documented" means the wetland is on the appropriate
state or federal database.
SP2. Has the wetland unit been documented as habitat for any State listed Threatened or
Endangered animal species? For the purposes of this rating system, "documented" means the ❑
wetland is on the appropriate state database. Note: Wetlands with State listed plant species
are categorized as Category 1 Natural Heritage Wetlands (see p. 19 of data form).
SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? ❑
SP4. Does the wetland unit have a local significance in addition to its functions? For example, the CI wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or
in a local management plan as having special significance.
To complete the next part of the data sheet you will need to determine the Hvdrogeomorphic Class of the wetland being rated.
The hydmgeomoiphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed • .n. er how well the wetland

If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt(parts per thousand)?
❑ YES—Freshwater Tidal Fringe ❑NO—Saltwater Tidal Fringe(Estuarine)
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it
is rated as an Estuarine wetland Wetlands that were call estuarine in the first and second editions of the rating system are called Salt
Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions,and
this separation is being kept in this revision. To maintain consistency between editions,the term"Estuarine"wetland is kept. Please
note,however,that the characteristics that define Category I and II estuarine wetlands have changed(see p. ).
2. The entire wetland unit is flat and precipitation is only source (>90%) of water to it. Groundwater and surface water
runoff are NOT sources of water to the unit.
®NO—go to 3 ❑ YES—The wetland class is Flats
If your wetland can be classified as a"Flats" wetland, use the form for Depressional wetlands.
3. Does the entire wetland meet both of the following criteria?
❑ The vegetated part of the wetland is on the shores of a body of permanent open water(without any vegetation on
the surface)where at least 20 acres(8ha) in size;
❑ At least 30% of the open water area is deeper than 6.6 (2 m)?
®NO—go to 4 ❑ YES—The wetland class is Lake-fringe (Lacustrine Fringe)
4. Does the entire wetland meet all of the following criteria?
® The wetland is on a slope (slope can be very gradual).
® The water flows through the wetland in one direction(unidirectional)and usually comes from seeps. It may flow
subsurface, as sheetflow, or in a swale without distinct banks.
❑ The water leaves the wetland without being impounded?
NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and
shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 foot deep).
®NO—go to 5 ❑ YES—The wetland class is Slope
5. Does the entire wetland meet all of the following criteria?
❑ The unit is in a valley or stream channel where it gets inundated by overbank flooding from that stream or river.
❑ The overbank flooding occurs at least once every two years.
NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding..
❑NO—go to 6 ❑YES—The wetland class is Riverine
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of
the year. This means that any outlet, if present is higher than the interior of the wetland.
❑NO—go to 7 ® YES—The wetland class is Depressional
7. Is the entire wetland located in a very flat area with no obvious depression and no overbank flooding. The unit does not
pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The
wetland may be ditched, but has no obvious natural outlet.
❑No—go to 8 ❑ YES—The wetland class is Depressional
8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example,seeps at the base of a
slope may grade into a riverine floodplain,or a small 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 10%of the unit,classify the wetland using the class that represents more than 90%of the total area.

(in addition to the protection recommended for its category)
SP1. Has the wetland unit been documented as a habitat for any Federally listed Threatened or
Endangered animal or plant species (T/E species)? ❑
For the purposes of this rating system, "documented" means the wetland is on the appropriate
state or federal database.
SP2. Has the wetland unit been documented as habitat for any State listed Threatened or
Endangered animal species? For the purposes of this rating system, "documented" means the ❑ El
wetland is on the appropriate state database. Note: Wetlands with State listed plant species
are categorized as Category 1 Natural Heritage Wetlands (seep. 19 of data form).
SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? ❑
SP4. Does the wetland unit have a local significance in addition to its functions? For example, the
wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or ❑
in a local management plan as having special significance.
To complete the next part of the data sheet you will need to determine the Hydrogeomorphic Class of the wetland being rated.
The hdrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions need..o .1 er how well the wetland
functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p.24 for more detailed 1 ,,,; ,, • classifying wetlands.

Classification of Vegetated Wetlands for Western Washington lI .
If the hydrologic criteria listed in each question do not apply to the entire unit being rated,rated,yo probably have a unit-With
multiple HGM classes. In this case, identify which hydrologic criteria in questio apply, and go to Question 8.
1. Are the water levels in the entire unit usually controlled by tides (i.e. except during floo•s)? a
®NO—go to 2 El YES—the wetlan4 class is Tidal Fringe '
If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt(••• •• san " E LOPM[NT
El YES—Freshwater Tidal Fringe 1=1 NO—Saltwater Tidal Fringe(Estuarine)
Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it
is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt
Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions,and
this separation is being kept in this revision. To maintain consistency between editions,the term"Estuarine"wetland is kept. Please
note,however,that the characteristics that define Category I and II estuarine wetlands have changed(seep. ).
2. The entire wetland unit is flat and precipitation is only source (>90%)of water to it. Groundwater and surface water
runoff are NOT sources of water to the unit.
®NO—go to 3 El YES—The wetland class is Flats
If your wetland can be classified as a"Flats" wetland, use the form for Depressional wetlands.
3. Does the entire wetland meet both of the following criteria?
❑ The vegetated part of the wetland is on the shores of a body of permanent open water(without any vegetation on
the surface)where at least 20 acres (8ha) in size;
El At least 30%of the open water area is deeper than 6.6 (2 m)?
®NO—go to 4 ❑ YES—The wetland class is Lake-fringe (Lacustrine Fringe)
4. Does the entire wetland meet all of the following criteria?
❑ The wetland is on a slope (slope can be very gradual).
El The water flows through the wetland in one direction(unidirectional)and usually comes from seeps. It may flow
subsurface, as sheetflow, or in a swale without distinct banks.
El The water leaves the wetland without being impounded?
NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and
shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 foot deep).
®NO—go to 5 ❑ YES—The wetland class is Slope
5. Does the entire wetland meet all of the following criteria?
❑ The unit is in a valley or stream channel where it gets inundated by overbank flooding from that stream or river.
❑ The overbank flooding occurs at least once every two years.
NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding..
®NO—go to 6 ❑YES—The wetland class is Riverine
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of
the year. This means that any outlet, if present is higher than the interior of the wetland.
El NO—go to 7 ® YES—The wetland class is Depressional
7. Is the entire wetland located in a very flat area with no obvious depression and no overbank flooding. The unit does not
pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The
wetland may be ditched,but has no obvious natural outlet.
El No—go to 8 El YES—The wetland class is Depressional
8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example,seeps at the base of a
slope may grade into a riverine floodplain,or a small 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 10%of the unit,classify the wetland using the class that represents more than 90%of the total area.
HGM Classes within the wetland unit being rated HGM Class to Use in Rating
Slope +Riverine Riverine
Slope+Depressional Depressional
Slope+Lake-fringe Lake-fringe
Depressional+Riverine along stream within boundary Depressional
Depressional+Lake-fringe Depressional
Salt Water Tidal Fringe and any other class of Treat as ESTUARINE under wetlands with special
freshwater wetland characteristics
If you are unable still to determine which of the above criteria apply to your wetland, or you hat t$t�n A{ lM classes
within a wetland boundary, classify the wetland as Depressional for the rating. tt 1 11 IVhf

HYDROLOGIC FUNCTIONS–Indicators that wetland unit functions to reduce flooding and stream degradation.
D 3 Does the wetland have the potential to reduce flooding and erosion? (see p.46)
D 3.1 Characteristics of surface water flows out of the wetland unit
• Unit is a depression with no surface water leaving it(no outlet) points=4
• Unit has an intermittently flowing, OR highly constricted permanently flowing outlet points=2
• Unit is a"flat"depression(Q.7 on key)or in the Flats class,with permanent surface 4
outflow and no obvious natural outlet and/or outlet is a man-made ditch points= 1 ❑
(If ditch is not permanently flowing treat unit as "intermittently flowing")
• Unit has an unconstricted,or slightly constricted, surface outlet(permanently flowing) points=0
D 3.2 Depth of storage during wet periods. Estimate the height of ponding above the bottom of the outlet. For
units with no outlet measure from the surface of permanent water or deepest part(if dry).
• Marks of ponding are 3 ft. or more above the surface or bottom of the outlet points=7
• The wetland is a"headwater"wetland points=5 _ 3

D 4 Does the wetland have the opportunity to reduce flooding and erosion? (see p. 49)
Answer YES if the unit is in a location in the watershed where the flood storage,or reduction in water velocity,
it provides helps protect downstream property and aquatic resources from flooding or excessive and/or erosive
flows. Answer NO if the water coming into the wetland is controlled by a structure such as flood gate,tide
gate,flap valve,reservoir etc. OR you estimate that more than 90%of the water in the wetland is from
groundwater in areas where damaging groundwater flooding does not occur. Note which of the following
indicators of opportunity apply.
Wetland is in a headwater of a river or stream that has flooding problems.
Wetland drains to a river or stream that has flooding problems
Wetland has no outlet and impounds surface runoff water that might otherwise flow into a river or
stream that has flooding problems Multiplier

❑YES multiplier is 2 ® NO multiplier is 1 1
• TOTAL—Hydrologic Functions Multiply the score from D3 by D4;then add score to table on p. 1
Comments: Much of the information is presumed based on professional experience and judgment with kettle wetland
systems dominated by spiraea. This rating is for all practical purposes, information provided to address wetland buffer
widths for compliance with being greater thand 300 ft from proposed land use development

Remarks:Small stands of slough sedge surrounded by dense salal and sword fern. Sedge stands are benched in the terrain and follow the
general topography. Water was observed as flowing and inundation tended to extend outward of the hydrophytes delineation. Stands are
no greater than 200 sq ft in area. Where absent,water meandered through upland vegetation in absence of a common channel. Moving
further upgradient,a channel forms intermittently in areas typically absent of hydrophytes. Hydrologic break occurs at culverted crossing,

WETLAND FUNCTION SUMMARY
Water Depressional with no outlet, persistent woody vegetation provides high function for water
Quality quality. Location within the landscape limits its opportunity to improve water quality.
Hydrologic Dense, uncut, herbaceous vegetation and no outlet provides high functional potential; down
gradient promotes the opportunity to reduce flooding or excessive and/or erosive flows.
Wildlife habitat functions are moderate with multiple special features, sustained buffers for
Habitat greater than 50 percent circumference. The wetlands proximity to other habitats and
landscape setting provides higher habitat function within the landscape.
Buffer Buffers are high quality for greater than 50 percent circumference.

All field inspections,jurisdictional wetland boundary delineations, and OHWM determinations were prepared
by, or under the direction of Robbyn Myers of BGE Environmental, LLC. Wetland status depicted in this report
has not been confirmed by a government official, and therefore has no confirmation of boundary or
regulatory requirement. Agencies with jurisdictional authority over wetlands and streams at the local, state
and federal level need to be consulted for their signed agreement to our findings before there is any
guarantee of no change. Our estimation for the accuracy of the unconfirmed wetland boundaries portrayed
within this report is >95% Please See Appendix E for a description of professional qualifications.

Chapter 5. Background Information
5.1 Research and Data Synthesis
Background research and data review is essential in the assessment of critical areas in the landscape,
providing past and present documentation of conditions and actions which impact, alter or define
natural resources subject to anthropogenic actions. Data researched included relevant mapping from
Jefferson County, U.S. Fish and Wildlife Service, Natural Resources Conservation Service, Washington

5.1.1 Natural Resources Conservation Service (NRCS)
The NRCS Web Soil Survey Map indicates over fifty percent of parcel consisting of (SnC) Sinclair
gravelly sandy loam with 0 to 15 percent slopes. Three addition soil series are mapped in the eastern
region of the property. These soils include (DaC) Dabob very gravelly sandy loam, 0 to 15 percent
slopes, (EvD) Everett gravelly sandy loam, 15 to 30 percent slopes, and (StB) Swantown gravelly sandy
loam, 0 to 8 percent slopes. A general description o each mapped soil type is provided below.
DaC Dabob very gravelly sandy loam, 0 to 15 percent slopes is composed of till located on
terraces. It is moderately well drained with a water table range from 18 to 36 inches.
Flooding and ponding frequency is absent and the prominent restrictive feature is a densic
material between 20 to 36 inches. The available water capacity is very low. Typical profile
character is very gravelly sandy loam to 33 inches and gravelly sandy loam at greater depths.
EvD Everett gravelly sandy loam, 15 to 30 percent slopes. This soil series is glacial outwash
found within the landform of terraces and escarpments. The drainage is somewhat
excessively drained with a deep restrictive feature at depths greater than 80 inches. Flooding
and ponding is typically absent with a water table at 80 inches. Water capacity is low. Profile
character is gravelly sandy loam from 0 to 6 inches, very gravelly sandy loam from 6 to 16
inches, and very gravelly coarse sand from 16 to6 0 inches.
SnC Sinclair gravelly sandy loam, 0 to 15 percent slopes is a basal till on a terraced setting.
This soil type is moderately well drained with a restrictive feature between 20 to 40 inches
densic. Water table depths are observed at about 18 to 36 inches below the surface and the
frequency of flooding and ponding is none. Available water capacity is very low. Gravelly
sandy loam is persistent from the surface to profile depths of 60 inches.
SnD Sinclair very gravelly sandy loam, 15 to 30 percent slopes is a basal till on till plains. This
soil series is moderately well drained with a water table depth at about 18 to 29 inches.
Restricted at 20 to 30 inches to densic material, both flooding and ponding are absent. This
also restricts water capacity and transmittal capability.
StB Swantown gravely sandy loam, 0 to 8 percent slopes is composed of till. The soils are
restricted by densic material between 20 to 30 inches. Drainage class is somewhat poorly
drained with a shallow water table about 6 to 12 inches. Frequency of both flooding and
ponding is reported as none. Available water capacity is very low. Typical soil profile is
gravelly sandy loam from 0 to 5 inches, very gravelly loam from 5 to 13 inches, and very
gravelly sandy loam from 13 to 60 inches. ,------ v

5.1.2 National Wetland Inventory (NWI)
The US Fish and Wildlife Service National Wetland Inventory map shows a single wetland fronting
Coyle Road in the northwest region of the property. This wetland is observed as severed with
additional wetland north of Coyle Road, across the street. The on-site wetland is mapped palustrine,
emergent (PEM) and palustrine, scrub shrub, (PSS), semi-permanently flooded (F). This wetland is
estimated at 1.31 acres in area. Additional NWI wetland areas include two PSSC; palustrine, scrub
shrub, seasonally flooded wetlands. The first is northeast of the parcel, opposite side of Coyle Road,
approximately 0.86 acres in area. The second is south within the rural residential setting off
Blueberry Hill Road and is 0.90 acres. Details of the Cowardin classification of the identified wetlands
is further defined below.
Palustrine (P) includes all non-tidal wetlands dominated by trees, shrubs, emergents, mosses
or mosses or lichens, and all such wetlands that occur in tidal areas where salinity due to
ocean derived salts is below 0.5 ppt. Wetlands lacking such vegetation are also included if
they exhibit all of the following characteristics: 1. are less than 8 hectares (20 acres); 2. do
not have an active wave-formed or bedrock shoreline feature; 3. have at low water a depth
less than 2 meters (6.6 feet) in the deepest part of the basin; 4. have a salinity due to ocean-
derived salts of less than 0.5 ppt.
Emergent (EM) is characterized by erect, rooted, herbaceous hydrophytes, excluding mosses
and lichens. This vegetation is present for most of the growing season in most years. These
wetlands are usually dominated by perennial plants.
Scrub Shrub (SS) includes areas dominated by woody vegetation less than 6 m (20 feet) tall.
The species include true shrubs, young trees (saplings), and trees or shrubs that are small or
stunted because of environmental conditions.
Semi-permanently Flooded (F) is when surface water persists throughout the growing season
in most years. When surface water is absent, the water table is usually at or very near the
land's surface.
Seasonally Flooded (C) surface water is present for extended periods especially early in the
growing season, but is absent by the end of the growing season in most years. The water
table after flooding ceases is variable, extending from saturated to the surface to a water
table well below the ground surface.
5.1.3 Stream Databases
The Department of Natural Resources Forest Practice Activity Map (FPARS) indicates a Type N water
central to the parcel, set north to south. The typed water originates south of the Coyle Road right-of-
way, directed to the south, southeast corner of the subject property. The Type N water continues off-
site with a change in stream segment typing to Type F water, occurring approximately 1,000+ feet
downstream from the property. Fish use is not documented in the entire stream reach, from the
subject parcel to the shores of Hood Canal.

5.1.4 WDFW Priority Species and Habitat
The WDFW Priority Habitats and Species (PHS on the Web) database indicates the parcel and vicinity as
being a management buffer to the Northern Spotted Owl (Strix occidentalis). Pursuant WDFW Policy
5210, the information concerning the specific locations of the species and habitats for the Northern
Spotted Owl (Strix occidentalis) is determined to be sensitive. Therefore the information provided by"PHS
on the Web" is generalized to the finest resolution allowable without a release agreement. Standard
format is presented in this report for the criterion determination of vicinity priority habitat and species for
the completion of the Washington State Wetlands Rating System for Western Washington — Revised
(Hruby, 2004).
Because this information is determined to be sensitive, we recommend further review of PHS for a
determination of project impacts. We understand that this level of review was completed by the
representing consultant, Adapt Engineering, and that the project is not occurring within a Northern
Spotted Owl Management Buffer Zone. As this information is confidential and not for general
distribution, the determination was provided through personal communications between Adapt
Engineering and BGE"c The Sensitive Fish and Wildlife Information Release Agreement with WDFW and
Adapt Engineering is proprietary and the information takes precedence over "PHS on the Web"
documentation.
With the exception of palustrine wetlands, no other priority habitat or species is reported. Species
documentation and listing status is summarized below in Table 1.

5.1.5 Jefferson County Mapping
The Critical Areas mapping presented on the Jefferson County website mimics wetland features as
provided through the NWI. An additional wetland area is shown associated with the Type N water
aforementioned above in Section 5.1.3, off-site to the south east. County mapping also delineates
the Typed water, however it is recorded as non-fish habitat for the entire reach.
5.1.6 WDNR Natural Heritage Database
According to Washington Department of Natural Resource (WDNR) records, no threatened or
endangered species of plants are recorded as present within Section 10, Township 26 North, Range
01 West, W.M. No threatened or endanger plant species were observed during the site investigation
and assessment.

6.1 Wetland Assessment and Delineation
The subject parcel was assessed on March 7, 2014 under clear skies, no re •rPde O.01dbn and a
' 0 P1 N DFVE:LOPM NT
daily ambient temperature variant of 45 to 53° F. The field assessment aria - dli Lelerrnina Orls
and delineations were conducted by Robbyn Myers, a Professional Wetland Scientist (#1286
Certification under the Society of Wetland Scientists). A routine wetland delineation was performed
in accordance with methods defined in Chapter 3 of this report.
Precipitation records were reviewed to coincide with field assessments from the Accuview weather
records. Daily and weekly precipitation data shows that 2.36 inches of rain fell within the two weeks
prior to the field assessment. Cumulative precipitation analysis indicates that the precipitation is
above normal for the two months of February and March. A summary of precipitation leading to the
field review and throughout the month is provided below in Table 2.

*Incomplete data set for March
The field investigation included the jurisdictional determination of on-site wetland and typing for
surface waters as defined in Chapter 3. The review area included off-site determinations with
obstructed views requiring aerial interpolation. The review area is defined at 300 feet perpendicular
to the project area, to include access road and lease area. An additional 50 feet was assessed for
areas off-site where quantitative delineation was not accessible. Figure 3 provides an aerial
depiction of the review area and findings of both on-site and off-site wetlands and surface waters.
Off-site investigations were limited to over the fence assessments to the landscape and roadside
peek-a-boos, mostly obstructed by vegetation and/or topography along Coyle Road. Data plots and
flagged wetland boundaries were recorded using a hand held, Trimble Juno GPS coordinate Datum
NAD83. Mapping was confirmed and corrected to aerial photographs.
Two wetlands, divided as three wetland units, were delineated within the subject parcel; Wetlands A,
B and C. One wetland, Wetland C, is the aforementioned NWI documented wetland complex. The
second wetland is down gradient but isolated from Wetland C, and is bound along the Type N water.
This wetland is severed by a jeep trail and culvert, providing a hydrologic break for wetland ratings to
Wetland A and Wetland B independently. Wetlands were alpha-numerically labeled as Wetlands A, B,
and C. For the purpose of this report, only the project facing side of the wetlands were field flagged
and delineated. However, Wetlands A and B are narrow and were easily interpolated to the mapping
on the wayward side. Wetland C was not investigated with great detail due to its proximity to the
proposed lease area outside of the 350 ft investigation area. Wetland C is over 500 ft away from the
project area. The Type N water is present in small segments with association to Wetland units A and
B. Its conveyance continues down gradient and off-site to the south east. There is no connectivity to
Wetland C. The character and documented Typing criterion are provided later in this report.

Off-site aerial interpolations summarized two potential wetland areas to the east of the project area;
Wetland 1 and Wetland 2. The wetlands could not be visually confirmed in the field as they are set
interior of Coyle road and visually obstructed by vegetation from the property boundaries. These
two wetland areas are presumed isolated from surface waters. Wetland 1 is a well defined signature
with comparison to other observed wetlands. Wetland 2 appears to be an area of ponding, not likely
to be a jurisdictional wetland. These wetland areas and the basis of conclusions are provided in the
following sections. Summaries of all critical areas are provided in Tables 4, 5, 6, 7, 8 and 9 later in this
Chapter.
6.2 On-site Wetlands
6.2.1 Wetland A
Wetland A consists of a series of small benches along the landscape. These benched areas were
observed as inundated and hydrophyte dominated. Water was ponding and flowing within and
around the emergent vegetation. This trend continued up gradient for the duration of the wetland
boundary. Typically the wetland was defined with slough sedge (Carex obnupta), although a few
areas included Pacific willow (Salix lasiandra), spiraea (Spiraea douglasii), and salmonberry (Rubus
spectabilis). Although associated with surface water flow, the wetland was not observed to retain a
channel, bank or a bed with the exception of one 60 ft reach in the proximity of delineation flag
WA03. Surface waters tended to be ponded beyond the dense non wetland vegetation border of
salal (Gaultheria shallon), evergreen huckleberry (Vaccinium ovatum) and common sword fern
(Polystichum munitum). The wetlands traverse is along the mapped Type N water although a channel
was absent for more than 90 percent of the identified wetlands distance. Soils were inundated,
prohibiting immediate and direct investigation. Water was ponded up to 6 inches and/or flowing.
Near delineation flag WA04 the wetland area becomes a long narrowed strip of slough sedge (Carex
obnupta) against a wall of salal (Gaultheria shallon), Western red cedar (Thuja plicata) and Douglas fir
(Pseudotsuga menziesii). Beyond this reach the wetland is an open water area, observed to be over
one foot in depth at the center. The wetland terminates to the north along a road slope with
decadent coverage of salal. A culvert provides hydrologic overflow from Wetland B (separate unit)
across the road.
Wetland A is palustrine emergent seasonally flooded (PEMC) under the Cowardin et al. (1979)
classification system. This wetland has a HGM classification of Slope. The wetland was rated as a
Category Ill wetland under the Ecology four-tiered rating system (Hruby 2004). Habitat score was 20.
Pursuant Title 18.22.330(2) JCC, for moderate impact land uses, the buffer width with an identified
wetland boundary (delineated) is 110 ft.
6.2.2 Wetland B
Wetland B is best defined as two emergent wetland areas connected by a small surface water. The
emergent vegetation cover in the southern reach is not as dense due to ponding along the road bed,
giving rise to far fewer and less dense stands of slough sedge (Carex obnupta), some observed as
submerged. As the wetland extends north inundation persists but the depths are reduced to a range
of three to seven inches (observed). Hydrophytes abruptly terminate where a shallow surface water
is observed through non wetland variety shrubs. The surface water continues for not more than 50
feet before the vegetation opens again to an emergent wetland complex. Although the dominate
vegetation is slough sedge (Carex obnupta), spiraea (Spiraea douglasii) and salmonberry (Rubus

individuals piercing through dense salal (Gaultheria shallon). Like Wetland A, the benched
topography sustained water volumes beyond the extent of the jurisdictional wetland boundary.
The wetland is carved into the landform and retains immediate and abrupt inclines to non wetland
areas in all direction. Its terminus is an abrupt slope to the north. Wetland B is palustrine emergent
semi-permanently flooded (PEMF) under the Cowardin et al. (1979) classification system. This
wetland has two HGM classifications; Slope & Depressional. The wetland was rated as a
depressional, Category III wetland under the Ecology four-tiered rating system (Hruby 2004). Habitat
score was 19. Pursuant Title 18.22.330(2) JCC, for moderate impact land uses, the buffer width with
an identified wetland boundary (delineated) is 60 ft.
6.2.3 Wetland C
Wetland C is a regionally documented wetland complex adjacent Coyle Road to the south. Due to its
proximity to the lease area, this wetland was not fully investigated. Rather the wetland boundary
was assessed with consistency to the jurisdictional criterion and other identified wetlands within the
subject parcel. The eastern boundary was flagged for confirmation of buffer width setbacks and
observed conditions were recorded. The wetland is present north of the upslope terminus to
Wetland B. First observed was inundation and spiraea (Spiraea douglasii) among salal (Gaultheria
shallon) and rhododendron (Rhododendron macrophyllum). This area had a higher species diversity
to include cleavers bedstraw (Galium aparine), osoberry (Oemleria cerasiformis), bracken fern
(Pteridium aquilinum) and an abundance of Himalayan blackberry (Rubus armeniacus). The central
region of the wetland, as viewed from higher points around the wetlands perimeter, was observed as
a monocultured stand of spiraea (Spiraea douglasii). Open water is observed in the interior from the
road side. Soils were inundated. Ponded areas were encountered well beyond the defined edge of
wetland prominent to non wetland prominent vegetation. The outer edge and wetland line is a hard
break to salal (Gaultheria shallon), Douglas fir (Pseudotsuga menziesii), evergreen huckleberry
(Vaccinium ovatum), red huckleberry (Vaccinium parvifolium), red alder (Alnus rubra) and common
sword fern (Polystichum munitum).
Wetland C is palustrine emergent semi-permanently flooded (PEMF) under the Cowardin et al. (1979)
classification system. The observed vegetation relationships along the landform are consistent with
the areas finding for Wetland A and B. This wetland is depressional according to HGM classification,
whereas if an outlet is present, it is higher than the interior of the wetland. There is no surface water
connection between Wetland C and the wetland area mapped north, immediately across and
adjacent Coyle Road. This wetland was not investigated thoroughly for the purpose of this report due
to its proximity to the lease area over 500 feet to the east. A wetland rating was complete with semi-
quantitative analysis. As the eastern region of the wetland area was delineated and field verified, the
entire unit was not covered, decreasing accuracy of the rating questions. The wetland rated as a
Category II wetland under the Ecology four-tiered rating system (Hruby 2004). Habitat score was 21.
Pursuant Title 18.22.330(2) JCC, for moderate impact land uses, the buffer width with an identified
wetland boundary (delineated) and a Habitat score of 21, is 110 ft.
6.3 Off-site Interpolations
6.3.1 Wetland 1
Pursuant Title 18.22.330(2)(b) JCC, if the wetland is located off of the property involved in the project
application and is inaccessible, the best available information shall be used to determine the wetland
boundary and category. Wetland 1 is set approximately 300 ft east of the project area. Off-site and
inaccessible for visual confirmation, this wetland has a similar signature to a wetland area north and
adjacent Coyle Road. It is presumed that the wetland is an isolated monocultured complex of spiraea

. .
with seasonal flooding. The buffer is a mature mixed forest, well established for over 50 percent
circumference. Therefore, the wetland is likely a depressional, PEMC, Category III wetland with a
Habitat score of less than 20. Pursuant Title 18.22.330(2) JCC, for moderate impact land uses, the
buffer width with an identified wetland boundary (delineated) is 60 ft, plus an additional distance of
30 feet from an apparent wetland boundary (not delineated). The applied buffer width under these
requirements suggests a minimum buffer width of 90 ft for Wetland 1.
6.3.2 Wetland 2
Pursuant Title 18.22.330(2)(b) JCC, if the wetland is located off of the property involved in the project
application and is inaccessible, the best available information shall be used to determine the wetland
boundary and category. Wetland 2 is set approximately 280 ft east of the project area and 150 ft
from the parcel boundary. It is off-site and inaccessible. The topography is a down gradient from the
parcel, off-site towards Wetland 2. Despite the topographical benefit to overlook the property, visual
confirmation was restricted with dense red alder saplings over eight feet in height. Aerial
interpolation suggests the area is a seasonal impoundment having no vegetation or limited
hydrophytes. Since the parcel was logged within the past 5 to 10 years, and the buffer surrounding
Wetland 2 is absent of mature canopy, we presume that Wetland 2 is not jurisdictional, and not a
wetland. Wetland 2 is presented here for due diligence of procedural review of potential critical
areas adjacent, off-site and with 350 ft of the project area. Valid rating information was unavailable.
6.4 Wetland Rating and Function
HGM classifications are used to more accurately assess wetland functions. The HGM classification is
based on three fundamental factors that influence how wetlands function: position in the landscape
(geomorphic setting), water source (hydrology), and the flow and fluctuation of the water once in the
wetland (hydrodynamics). Functions and values for wetlands within the project vicinity were
classified under hydrogeomorphic method (HGM) and evaluated using the Washington State
Wetlands Rating System for Western Washington — Revised (Hruby, 2004). The methodology does
not assign quantitative values to a particular function, but identifies functional strengths and
weaknesses to help guide management decisions and aid in mitigation choices. Wetland functions are
divided into 14 categories. The function and value of identified wetland units, Wetland A, B and C,
are summarized below in Table 3. No functional assessment can be made with accuracy to off-site
wetland areas, Wetland 1 and Wetland 2.
6.5 Upland Descriptions
Uplands within the subject parcel and surrounding Wetlands A, B and C are mature mixed forest of
Douglas fir (Pseudotsuga menziesii), Western red cedar (Thuja plicata), Western hemlock (Tsuga
heterophylla), bigleaf maple (Acer macrophyllum), Western white pine (Pinus monticola) and red
alder (Alnus rubra). The understory and shrub layer is decadent in most areas and include salal
(Gaultheria shallon), Pacific rhododendron (Rhododendron macrophyllum), salmonberry (Rubus
spectabilis), evergreen huckleberry (Vaccinium ovatum) and other natives. Ground covers were
primarily defined with common sword fern (Polystichum munitum) with grasses and forbes dominant
in clearings or areas of reduced or absent canopy closures.
Invasive species were sparse and typically noted to the topographical knoll at and near the project
area where the existing roads have disturbed native species distribution and abundance. These roads
are rough and slightly overgrown. They encircle the knoll and continue to the south, severing
Wetland unit A and B with an elevated culvert. The roads continuation off-site to the south was not
investigated. Uplands surrounding Wetlands A, B and C were typically inundated under dense salal
(Gaultheria shallon), as the topography is high gradient with benched relief or gradual within the

ecotone. Soils were a medium brown sandy loam. Despite the presence of hydrology, nonhydric
soils and the predominance of upland vegetation are evidence that these areas do not meet wetland
criteria.

6.6 Type N Water
One surface water was observed intermittently within Wetland B and Wetland A with a continuation
of flow off-site to the south, southeast. Most often a channel was absent although misdirected flow
through inundated topography. Two areas with a segment length not greater than 80 feet
independently within Wetlands A and B were likely definable as a Typed water under Washington
Department of Natural Resources (DNR) Water Typing System as outlined in the Washington
Administrative Code (WAC) Section 222-16. The surface water was not assessed in detail for the
purpose of this report and is not challenged with a Type N status. Observed channels were noted and
mapped for reporting and buffer application provisions. Pursuant Title 18.22.270(1) the buffer
requirement is 75 ft. A summary of the Type F is provided in Table 8 at the end of this Chapter.

Water Relatively steep slopes, benched with ponding among dense, uncut, herbaceous vegetation
Quality provides high function for water quality. Location within the landscape limits its opportunity
to improve water quality.
Dense, uncut, herbaceous vegetation and benched topography provides high functional
Hydrologic potential; while limited downstream resources removes the opportunity to reduce flooding
or excessive and/or erosive flows.
Wildlife habitat functions are moderate with multiple special features, sustained buffers and
Habitat interspersions and complexity. The wetlands proximity to other habitats and landscape

Dear Mr. Chang:
The final Wetland Delineation report for the host parcel of project"BR0266/ Bangor Canal" is attached.
As requested by Jefferson County, all wetlands within 350-feet of the project area were delineated, rated
(using Department of Ecology's Western Washington Rating System) and buffer width requirements were
determined. Three on site wetlands were located within 350' of the project area. It was determined that
the proposed communications tower project will not be located within the buffer zone of those wetlands.
Adapt does not believe that any Federal, State or local permits will be required for this project, nor that
any mitigation will be necessary.
If you have any further questions, please contact me at(503)892-2346 or by email at

EXECUTIVE SUMMARY
AT&T Mobility Corporation (Applicant) is proposing a land lease agreement, utility easement and
cell tower construction/operation within a 20.48 acre parcel, undeveloped, in unincorporated
Jefferson County Washington. A routine wetland determination was completed within a 350 foot
perimeter review area to the proposed facilities and use; includes access road and cell tower lease
area. The review area included off-site assessments in which access was prohibited and aerial
interpolation with professional judgment applied. Two wetlands were identified on the subject
parcel, one of which was within the 350 foot review area. This wetland was hydrologically divided
into two wetland units delineated here as Wetland A and Wetland B. These wetland complexes are
associated with a Type N water which continues towards the south east corner of the subject
parcel. The second wetland system is outside the review area but its eastern boundary was
delineated for mapping accuracy. This wetland is defined as Wetland C and was generally assessed
along its eastern and northern boundary. All three wetland areas were field delineated along the
eastern boundary, project facing, and interpolated to the west. On-site Wetlands A and B are
Category Ill, Wetland C is a Category II under the Ecology four-tiered rating system (Hruby 2004).
Off-site aerial interpolations summarized two potential wetland areas to the east of the project
area; Wetland 1 and Wetland 2. The wetlands were inaccessible and could not be visually
confirmed in the field as they are set interior of Coyle road and visually obstructed by vegetation
from the property boundaries. These two wetland areas are presumed isolated from surface
waters. Wetland 1 is a well defined signature with comparison to the observed Wetland C on-site
and an additional wetland adjacent Coyle Road to the north. Wetland 2 appears to be an area of
possible ponding, but it was determined that this area is not likely a jurisdictional wetland. There
was not significant enough information to complete a wetland rating for either of the interpolated
wetland areas. Wetland ratings and criterion confirmation are strictly based on the assessments of
other jurisdictional wetlands reviewed under the scope of this report.
Habitat and species evaluation for the project area indicates the parcel and vicinity as being a
management buffer to the Northern Spotted Owl (Strix occidentalis)1. With the exception of
palustrine wetlands, not other priority habitat or species is reported nor observed.

Chapter 3. Methods
This chapter summarizes the methods used to assess, delineate and confirm jurisdictional critical
areas within and adjacent to the subject parcel. The methodology used is consistent and compliant
with federal, state, and local regulations. Please see Appendix A for methodology references and
tools used in the assessment for this report.
The wetland, surface waters and other potentially regulated fish and wildlife habitat onsite were
assessed by a Professional Wetland Scientist (PWS) on March 7, 2014. Potentially regulated critical
areas were inspected and delineated where determined jurisdictional under federal, state and local
regulations. All wetland determinations were completed using observable and documented
assessments of vegetation, hydrology, and soils. When applicable, ordinary high water mark
(OHWM) determinations were made using observable vegetation, hydrology, and soils with
precedence to bank full width determination. All determinations were concluded in conjunction with
data from the National Wetland Inventory, Jefferson County Mapping, maps of the U.S. Fish and
Wildlife Service, the Soil Survey of Jefferson County, and various visual and aerial photographs. See
Appendix B for maps detailing background data such as soils, topography, and resource inventories.
Wetland boundaries were determined using the Interim Regional Supplement to the Corps of
Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region. Wetland
Regulatory Assistance Program, Army Corps of Engineer. April 2008. This document is one of a series
of Regional Supplements to the Corps of Engineers Wetland Delineation Manual, which provides
technical guidance and procedures for identifying and delineating wetlands that may be subject to
regulatory jurisdiction under Section 404 of the Clean Water Act or Section 10 of the Rivers and
Harbors Act. The supplement is applicable to the Western Mountains, Valleys, and Coast Region,
which consists of portions of 12 states, including Arizona, California, Colorado, Idaho, Montana,
Nevada, New Mexico, Oregon, South Dakota, Utah, Washington and Wyoming. The Regional
Supplement is designed for use with the current version of the Corps Manual (Environmental
Laboratory 1987) and all subsequent versions.
Vegetation determinations were based on the analysis of the plant community that is normally
present during the wet portion of the growing season in a normal rainfall year. This determination
was weighted by the wetland indicator status of the plant species identified on-site. Indicator status
was minimized to the five basic levels (i.e., OBL, FACW, FAC, FACU, and UPL) approved by
Headquarters, U.S. Army Corps of Engineers'.
The procedure for using hydrophytic vegetation indicators is sequentially applied as follows:
• Apply Indicator 1, Dominance Test, where the plant community passes the dominance test,*
• Apply Indicatory 2, Prevalence Index, if plant community fails dominance test but indicators
of hydric soil and wetland hydrology are both present,*
• Apply Indicators 3, Morphological Adaptations, and/or 4, Wetland Non-Vascular Plants, where
either indicator is satisfied, the vegetation is hydrophytic.*
Hydric soil determinations were confirmed if one or more of the following characteristics were
present:

• Organic soils or soils with an organic surface layer,
• Matrix chroma just below the A-horizon (or 10-inches, whichever is less) of 1 or less in
unmottled soils, or 2 or less if mottles were present, or
• Gleying immediately below the A-horizon.
Indicators of wetland hydrology may include, but are not necessarily limited to: drainage patterns,
drift lines, sediment deposition, watermarks, historic records, visual observation of saturated soils,
and visual observation of inundation.
OHWM's were determined using Ecology's method as detailed in Determining the Ordinary High
Water Mark on Streams in Washington State (Olson, 2008) and definitions provided in RCW
77.55.011 (11) and WAC 220.110.020 (69). Drainages not associated with wetland conditions were
driven by a consistent and observable bank which provided a conservative, yet clear demarcation of a
surface water conveyance. Streams and surface water features were classified using both the
Washington Department of Natural Resources (DNR) Water Typing System as outlined in the
Washington Administrative Code (WAC) Section 222-16.
Wetland boundaries and associated drainages were inspected, delineated and mapped to Trimble
JUNO, GPS Datum NAD83. To mark the boundary between wetlands and uplands, orange surveyor's
flagging was alpha-numerically labeled and tied to vegetation or wood lath along the wetland
boundary. To mark the points where data was collected, additional surveyor's flagging or pin flags
were alpha-numerically labeled and tied or driven, at each sampling location. OHWM, or bank full
width, of the regulated streams was not delineated with flagging for the purposes of this report and
as wetland conditions were well defining of the feature.
Wetlands were classified using both the hydrogeomorphic (Brinson, 1993) and Cowardin (Cowardin,
1979) classification systems. Following classification, all wetlands were rated and categorized using
both the Washington State Wetlands Rating System for Western Washington — Revised (Hruby, 2004).
Streams and surface water features were classified using both the Washington Department of Natural
Resources Water Typing System as outlined in described in the Washington Administrative Code
(WAC) Section 222-16.
The fish and wildlife habitat assessment was conducted by qualified biologists during the same site
visits. Publicly available background data was queried for documented wildlife observations and/or
the presence of potentially regulated fish and wildlife habitat on or near the site. Data inquiries were
conducted using the "PHS on the Web", an interactive mapping tool through the Washington
Department of Fish and Wildlife. The data displayed on "PHS on the Wed" is for informational
purposes only and utilized in accordance to criterion requirements for wetland rating methodology
for Western Washington, Version 2 (7/06), updated with new WDFW definitions Oct. 2008 (Hruby,
2004). In addition, high-resolution aerial photography of the surrounding area was carefully
examined. Visual observations using stationary and walking survey methods were utilized for both
aquatic and upland habitats. Any special habitat features or signs of wildlife activity were noted.

Chapter 4. Existing Conditions
4.1 Landscape Setting
The subject parcel is located on the Dabob peninsula, nearly central to the landscape. The peninsula
is a mix of inholding and commercial forestry land, rural forest and rural residential. It includes a US
Naval Reservation buffer to the Bangor Naval Base across the Hood Canal to the east. Rural
residential parcels tend to be clustered off the main arterial of Coyle Rd. Shorelines development is
select in areas. Other developments to the peninsula are centered to the south in Coyle, a small
residential community with public boat launch and mooring facility within Fisherman Harbor. Silent
Lake is the peninsulas only significant water feature with the exception of numerous streams.
Documented wetlands are few and interspersed central to the landscape, typically classified as
freshwater ponds. Larger mapped wetlands are forested/scrub-shrub. See Figure 2 for aerial of
surrounding land use.
4.2 Parcel Specific Characteristics
The subject parcel is triangular in shape, fronting Coyle Road to the north. It includes and access
easement or panhandle in the southwest, at a turn in road. The parcel is forested under a mix of
conifers to include Douglas fir, Western red cedar, Western hemlock and American white pine.
Understory and shrub components are dense natives of salal, red huckleberry, evergreen
huckleberry, salmonberry, Pacific rhododendron. Sword fern is common. The landform is hilly in the
north with an elevation decline sloping both south west, south east and due east. A rough access to
the parcel is present off Coyle Rd; gated, rough and hardened with opportunistic red alder saplings
establishing within the interior. This access road rises to the height of the property, circling the knoll.
Another road merges to the south, where it crosses wetlands and surface waters. The road continues
off the parcel to the southern property.
One large wetland complex is apparent in the western region of the parcel. This wetland is palustrine
scrub-shrub. A mapped surface water set in the south eastern region was investigated to include
sloped wetland complexes associated with an intermittent channel. Wetlands are palustrine
emergent.
Immediately east, the adjacent parcel landscape is recovering from logging (approximated to have
occurred over five years prior) with dominate red alder and a dense shrub component. Immediately
south, rural residential homesites are aligned and perpendicular to Blueberry Hill Drive. To the north,
beyond Coyle Rd the parcel frontage is undeveloped, forested with a documented wetland.
