Wetland Delineation Report 1 August 2015
INTRODUCTION
Ecological Land Services, Inc. (ELS)was contracted by Tim Wilkins to complete a wetland
delineation and report for the property on Gybe Ho Road,which is comprised of parcel number
921092007 in Section 9, Township 29 North, and Range 1 West of the Willamette Meridian within
the Nordland area of Jefferson County, Washington (Figure 1).This report summarizes findings of
the wetland delineation according to the Jefferson County Unified Development Code,Chapter
18.22,Critical Areas (JCUDC).
METHODOLOGY
The wetland delineation followed the Routine Determination Method according to the U.S. Army
Corps of Engineers,Wetland Delineation Manual (Environmental Laboratory 1987)and the
Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains,
Valleys and Coast Region, Version 2.0 (U.S. Army Engineer Research and Development Center
2010).
Delineations of undisturbed wetlands is typically conducted using the Routine Determination
Method, which examines the three parameters—vegetation, soils, and hydrology—to determine if
wetlands exist in a given area.Hydrology is critical in determining what is wetland, but is often
difficult to assess because hydrologic conditions can change periodically (hourly, daily, or
seasonally).Consequently, it is necessary to determine if hydrophytic vegetation and hydric soils
are present, which would indicate that water is present for long enough duration to supp ort a
wetland plant community.By definition, wetlands are those areas that are inundated or saturated by
surface 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 soil
conditions.Wetlands are regulated as “Waters of the United States” by th e U.S. Army Corps of
Engineers (USACE),as “Waters of the State”by the Washington Department of Ecology
(Ecology), and locally by Jefferson County.
The onsite wetland has been significantly disturbed by construction of a driveway, clearing of
forested vegetation, dredging, and spread of dredge spoils. Portions of the buffer have also been
impacted by these activities. Because of the disturbance, the Atypical Situations Method for
Unauthorized activities of the referenced delineation manual and supplement was utilized to
delineate the wetland boundary.The Atypical Situations Method examines the disturbance and
utilizes the least impacted parameter to determine the presence or absence of the wetland.For this
delineation, the hydric soil criterion was the most reliable because both hydrophytic vegetation and
wetland hydrology parameters were significant disturbed. The presence of hydrophytic vegetation
and wetland hydrology prior to the disturbance was assumed present by the observation of hydric
soil indicators particularly in the areas disturbed by spread of dredge spoils.
To determine the presence or absence of wetlands on this property, ELS biologists collected data
on soils in the disturbed areas and vegetation, hydrology, and soils in the undisturbed portions of
the property. During the site visit,one wetland was identified on the property. The onsite forested
wetland lies across the west half of the property on sloping terrain.The wetlands were delineated
Wilkins-Gybe Ho Road Property Ecological Land Services, Inc.
Wetland Delineation Report 2 August 2015
using consecutively numbered fluorescent flagging labeled “WETLAND BOUNDARY”.Wetland
boundaries were determined through breaks in topography, changes in vegetation, and evidence of
surface hydrology.Vegetation, hydrology, and soil data was collected at fourteen test plots to
verify the wetland boundary delineations (Appendix A). The wetland boundary and test plot flags
were located using the Magellan Triton handheld Global Positioning System (GPS)unit and are
shown on Figure 2.
Undisturbed portions of the wetland remain to the north and south of the disturbances and
represent conditions that were most likely present in the disturbed areas. The wetland extends
offsite to the south and ends at Gybe Ho Road where there is currently a small raised culvert under
the road (Photoplate 10).
SITE DESCRIPTION
The property is located at the end of Gybe Ho Road in the Nordland area of Jefferson County
(Figure 1).Gybe Ho Road runs east of State Highway 116 just after it enters Marrowstone Island.
The property is located at the north end of a gravel drive that leaves Gybe Ho Road as it ends.It is
rectangular in shape and is oriented east to west (Figure 1). The topography is undulating to flat
with a shallow linear trough oriented north to south across the east end of the property. It is
currently undeveloped but portions of the east half were recently cleared and a driveway was
constructed about midway across the east half (Figure 2). Soil logs have been conducted by a
septic system designer to prepare a septic system site plan for future development.A fence is
proposed just inside the perimeter of the property (Figure 2).The fence and property lines have
been staked around the entire property.
The delineated wetland is situated in the depressional trough across the east half of the property. A
large portion of the wetland has been disturbed by construction of the driveway, dredging of the
south half of the wetland, and spread of dredge spoils (Photoplates 1 through 4). Undisturbed
forested wetland remains north and south of the disturbed area and represents the historic condition
of the disturbed wetland (Photoplates 4 and 6). The wetland begins just north of the disturbance
and extends south to Gybe Ho Road where it often floods the roadway. A small pipe was installed
across the road to facilitate drainage under the road and avoid flooding (Photoplate 10). The
remainder of the site is composed of upland forest with a dense shrub understory. In some areas,
wetland plant species and wetland hydrologic indicators were observed, but these areas are upland
because they lack positive indicators for hydric soils (Photoplate 8). These areas appear to be old
logging roads where surface water collects for short periods during the winter.
There are depressional wetlands offsite to the east (Offsite Wetland A)and west (Offsite Wetland
B). These wetlands extend just to the property line and do not continue onto the property so do not
connect to the onsite wetland. There may be some overland flow from the wetland to the east but
there is no continuous wetland across the property line and into the onsite wetland. Although the
wetlands do not extend onto the property, the buffers required from each one will extend onto the
east and west ends of the property.

VEGETATION
Prior to the disturbance, the entire onsite wetland was composed of a depressional forested system
judging by the vegetation cover observed in the undisturbed wetlands north and south of the
disturbed area. The dominant species included red alder (Alnus rubra, FAC), salmonberry (Rubus
spectabilis, FAC), slough sedge (Carex obnupta, OBL), lady fern (Athyrium filix-femina, FAC),
and water parsley (Oenanthe sarmentosa, OBL). The disturbed areas of the wetland were mostly
bare of vegetation with some of the wetland plant species growing up through the fill including
slough sedge and water parsley. The Offsite Wetlands A and B are also composed of depressional
forested wetlands that are dominated by the same plant species.
The upland areas of the property are composed of a mixed forest dominated by Douglas fir
(Pseudotsuga menziesii, FACU), western red cedar (Thuja plicata, FAC), western hemlock (Tsuga
heterophylla, FACU), grand fir (Abies grandis, FACU), bigleaf maple (Acer macrophyllum,
FACU), Scouler’s willow (Salix scouleriana, FAC), and red alder in the forest canopy. Most of
the shrub layer is very densely vegetated and dominated by salmonberry, ocean spray (Holodiscus
discolor, FACU),red elderberry (Sambucus racemosa, FACU),salal (Gaultheria shallon, FACU),
and Oregon grape (Mahonia nervosa, FACU). The herbaceous layer is dense where the shrub
cover is more sparse and is dominated by sword fern (Polystichum munitum, FACU),cleavers
(Galium aparine, FACU),trailing blackberry (Rubus ursinus, FACU), and Siberian miner’s lettuce
(Claytonia sibirica, FAC).Slough sedge is present in some areas of the upland that appear to be
old logging roads but is generally not a dominant species.
The dominant vegetation found onsite is recorded on the attached wetland determination data
forms (Appendix A). The indicator status, following the common and scientific names, indicates
how likely a species is to be found in wetlands. Listed from most likely to least likely to be found
in wetlands, the indicator status categories are:
OBL (obligate wetland)–Almost always occur in wetlands.
FACW (facultative wetland)–Usually occur in wetlands, but may occur in non-wetlands.
FAC (facultative)–Occur in wetlands and non-wetlands.
FACU (facultative upland)–Usually occur in non-wetlands,but may occur in wetlands.
UPL (obligate upland)–Almost never occur in wetlands.
NI (no indicator)–Status not yet determined.
SOILS
As referenced on the U.S.D.A. Natural Resources Conservation Service (NRCS 2015) website,
Whidbey gravelly sandy loam, 15 to 30 percent slopes (WhC)is mapped for this property (Figure
3).Whidbey soils are not classified as hydric and but can have inclusions of hydric soils in
depressions (NRCS 2014).Areas mapped as hydric soils do not necessarily mean that an area is or
is not a wetland—hydrology, hydrophytic vegetation, and hydric soils must all be present to
classify an area as a wetland.
The evaluated wetland soils in the undisturbed areas (Test Plots 1 and 8)were composed of muck
to gravelly loam with black to yellowish-brown (10YR 3/1 to 2.5Y 3/2) soil matrix colors.
Wilkins-Gybe Ho Road Property Ecological Land Services, Inc.
Wetland Delineation Report 4 August 2015
Redoximorphic features were present in each of the subsurface soil layers occurring as
concentrations within the matrix and having brownish red (10YR 4/4 to 10YR 4/6) colors.The
soil within the disturbed areas of the onsite wetland (Test Plots 4 and 5) revealed identical profiles
consisting of at least 4 inches of dredge spoil material over the native soil. The dredge spoil layer
consisted of a silt loam that has a dark brown (10YR 2/2) matrix color with no redoximorphic
features. The native profile consisted of silt loam to gravelly sandy loam with dark brown to
yellowish brown (10YR 2/1 to 2.5Y 3/2) matrix colors. The lower horizon in the native soil
contained concentration type redoximorphic features covering about 15 percent of the matrix and
have a reddish (10YR 4/4) color.Each of the soil profiles was determined to meet hydric soil
indicators A11 and A12 due to the dark soil surface layers over depleted matrix subsurface layers.
The evaluated upland soils consisted of gravelly sandy loam that had black to yellowish-brown
(7.5YR 4/4 to 2.5Y 5/2) soil matrix colors.Redoximorphic features were observed in several of
the upland soil profiles but were determined to be non-hydric because the soil conditions did not
meet the descriptions for any of the hydric soil indicators.
HYDROLOGY
Water was not present in any of the wetland test plot areas during the field delineation; however,
evidence of seasonal flooding was present in each area.The indicators of wetland hydrology
include bare ground, algal mats, and water stained vegetation. Oxidized rhizospheres were
observed in several of the wetland plots indicating the soil saturation also occurs when the wetland
is flooded.The source of hydrology is primarily a shallow water table that rises to the surface
during the winter and early growing season. Additional sources of water include direct rainfall and
surface water runoff.The wetland drains southerlyn and flows across Gybe Ho Road (Photoplate
11) and into offsite wetlands south of the road. The Offsite Wetlands A and B have similar
characteristics as the onsite wetland with regard to the presence of wetland hydrology indicators.
The Offsite Wetland A appears to intermittently flow across the property line and into the onsite
wetland. The outlet from the Offsite Wetland B was not observed during the field delineation but
it appears that it outlets either to the north or west. Evidence of surface water was observed at
several of the upland test plot areas but primarily in areas that appear to be old logging roads where
water collects in the winter and early spring. These areas were determined to be upland based on
the absence of hydric indicators within the soil profiles.
NATIONAL WETLAND INVENTORY
The National Wetlands Inventory (NWI)map does not show wetlands on or within 250 feet of the
property (Figure 4).The findings of the ELS delineation do not agree with the NWI mapping
because wetland was identified on and adjacent to the property.The NWI maps should be used
with discretion because they are used to gather general wetland information about a regional area
and therefore are limited in accuracy for smaller areas because of their large scale.

JEFFERSON COUNTY CRITICAL AREAS
The Jefferson County Critical Areas map (JC 2015) does not indicate the presence of wetlands on
or within 250 feet of the property (Figure 5). The ELS biologist disagrees with the JC map because
wetlands were identified on and adjacent to the property (Figure 2).
CONCLUSIONS
WETLAND CATEGORIZATION
The onsite wetland is situated in a shallow depression that ends at Gybe Ho Road south of the
property.This wetland was rated according to Washington State Wetlands Rating System for
Western Washington,2014 Update (Rating System)(Hruby 2014).It scored 18 points on the
rating form and is considered a Depressional,Category III forested wetland based on functions
(Appendix B).The wetland scored 6 points for habitat functions, which is a moderate rating. The
boundaries of the Offsite Wetlands A and B were not formally delineated except in the small areas
where boundary flags were placed to identify their location. Although most of the offsite
boundaries were not observed during the field visit, each of these wetlands are depressional with a
similar hydrophytic vegetation, hydric soil, and wetland hydrology conditions as the onsite
wetland. Therefore,Offsite Wetlands A and B are also determined to be depressional, Category III
forested wetlands based on functions.
CRITICAL AREA REGULATIONS
The JCUDC Chapter 18.22 specifies buffers based wetland category, scores for habitat functions
on the rating form, and the intensity of the proposed land use in accordance with the 2004 wetland
Rating System. The JCUDC has been revised to reflect the 2014 rating system scores and reflects
the new point totals for determining the buffer widths based on habitat scores. Each of the
wetlands identified on and offsite are determined to be Category III systems with mo derate scores
for habitat functions so a buffer of 110 feet will be required (Figure 2).A 15-foot building and
impervious surface setback is specified from the edge of stream and wetland buffers.
LIMITATIONS
The conclusions listed above are based on standard scientific methodology and best professional
judgment. In our opinion, local, state, and federal regulatory agencies should agree with our
conclusions; however, this should be considered a preliminary jurisdictional determination and
should be used at your own risk until it has been reviewed and approved in writing by the
appropriate regulatory agencies.

Road. It looks southwesterly
from the start of the driveway
constructed earlier this year. The
photo shows the south half of the
disturbed wetland and buffer area
for which restoration will be
conducted.
Photo 3 is taken from the same
location as Photos 1 and 2. It
looks northwesterly toward the
undisturbed forested wetland
area immediately north of the
impacted wetland and buffer
area.Photo 2 is taken from the same
location as Photo 1 and looks north
along the trail. The area beyond
the maple tree on the right is a
historic clearing that is now
dominated by blackberry thickets.

Photo 4 was taken on May 15,
2015 from the driveway at the
culvert installed to allow water
flow from one side to the other.
The area shown is primarily
wetland that was dredged during
construction of the driveway.
The wetland extends up the slope
on both sides of the created
drainage.
Photo 6 is taken on the same
day and from the same location
as Photo 5. It looks across the
disturbed area of wetland west
of the drainage channel
pictured in Photos 4 and 5.It
looks like the spoils from the
excavated area were spread
across this area of wetland so
represents wetland fill.
Photo 2 is taken from the same
location as Photo 1 and looks north
along the trail. The area beyond
the maple tree on the right is a
historic clearing that is now

conducted, which is along the
north property line and
downslope of offsite wetland A.
This area is not wetland due to
the dominance of non-wetland
plant species and lack of hydric
soil indicators even though there
is evidence of short-term surface
water.
Photo 27 is taken from near
Test Plot 16 and looks south

HGM Classification of Wetlands in Western Washington
For questions 1-7,the criteria described must apply to the entire unit being rated.If the hydrologic criteria listed in each question do not apply to the entire unit being rated,youprobablyhave a unit with multiple HGM classes.In this case,identify which hydrologic criteria inquestions 1-7 apply,and go to Question 8.1.Are the water levels in the entire unit usually controlled by tides except during floods?
NO –go to 2 YES –the wetland class is Tidal Fringe –go to 1.11.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)?
NO –Saltwater Tidal Fringe (Estuarine)YES –Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands.If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored.This method cannot be used to
score functions for estuarine wetlands.2.The entire wetland unit is flat and precipitation is the only source (>90%)of water to it.Groundwaterandsurfacewaterrunoffare 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 unit meet all of the following criteria?The vegetated part of the wetland is on the shores of a body of permanent open water (without anyplants on the surface at any time of the year) at least 20 ac (8 ha) in size;At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO –go to 4 YES –The wetland class is Lake Fringe (Lacustrine Fringe)4.Does the entire wetland unit 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 fromseeps.It may flow subsurface,as sheetflow,or in a swale without distinct banks,The water leaves the wetland without being impounded.
NO –go to 5 YES –The wetland class is Slope
NOTE:Surface water does not pond in these type of wetlands except occasionally in very small andshallowdepressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ftdeep).5.Does the entire wetland unit meet all of the following criteria?The unit is in a valley, or stream channel,where it gets inundated by overbank flooding from thatstream or river,The overbank flooding occurs at least once every 2 years.
Wetland name or number on andoffsite wetlands
Wetland Rating System for Western WA:2014 UpdateRatingForm–Effective January 1,2015 4
NO –go to 6 YES –The wetland class is Riverine
NOTE:The Riverine unit can contain depressions that are filled with water when the river is notflooding6.Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to thesurface,at some time during 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 Depressional7.Is the entire wetland unit located in a very flat area with no obvious depression and no overbankflooding?The unit does not pond surface water more than a few inches.The unit seems to bemaintainedbyhighgroundwater in the area.The wetland may be ditched,but has no obvious naturaloutlet.NO –go to 8 YES –The wetland class is Depressional8.Your wetland unit seems to be difficult to classify and probably contains several different HGMclasses.For example,seeps at the base of a slope may grade into a riverine floodplain,or a smallstreamwithin a Depressional wetland has a zone of flooding along its sides.GO BACK AND IDENTIFYWHICHOFTHEHYDROLOGICREGIMESDESCRIBEDINQUESTIONS1-7 APPLY TO DIFFERENTAREASINTHEUNIT(make a rough sketch to help you decide).Use the following table to identify theappropriateclass to use for the rating system if you have several HGM classes present within thewetland unit being scored.
NOTE:Use this table only if the class that is recommended in the second column represents 10% ormore of the total area of the wetland unit being rated.If the area of the HGM class listed in column 2is less than 10% of the unit; classify the wetland using the class that represents more than 90% of thetotal area.

Check off any criteria that apply to the wetland.Circle the category when the appropriate criteria are met.
Category
SC 1.0.Estuarine wetlands
Does the wetland meet the following criteria for Estuarine wetlands?
The dominant water regime is tidal,
Vegetated,and
With a salinity greater than 0.5 ppt Yes –Go to SC 1.1 No=Not an estuarine wetland
SC 1.1.Is the wetland within a National Wildlife Refuge,National Park,National Estuary Reserve,Natural Area
Preserve,State Park or Educational,Environmental,or Scientific Reserve designated under WAC 332 -30-151?
Yes =Category I No -Go to SC 1.2 Cat.I
SC 1.2.Is the wetland unit at least 1 ac in size and meets at least two of the following three conditions?
The wetland is relatively undisturbed (has no diking,ditching,filling,cultivation,grazing,and has less
than 10%cover of non-native plant species.(If non-native species are Spartina,see page 25)
At least ¾ of the landward edge of the wetland has a 100 ft buffer of shrub,forest,or un-grazed or un-
mowed grassland.
The wetland has at least two of the following features:tidal channels,depressions with open water,or
contiguous freshwater wetlands.Yes =Category I No =Category II
Cat.I
Cat.II
SC 2.0.Wetlands of High Conservation Value (WHCV)
SC 2.1.Has the WA Department of Natural Resources updated their website to include the list of Wetlands of High
Conservation Value?Yes –Go to SC 2.2 No –Go to SC 2.3
SC 2.2.Is the wetland listed on the WDNR database as a Wetland of High Conservation Value?
Yes =Category I No =Not a WHCV
SC 2.3.Is the wetland in a Section/Township/Range that contains a Natural Heritage wetland?
http://www1.dnr.wa.gov/nhp/refdesk/datasearch/wnhpwetlands.pdf
Yes –Contact WNHP/WDNR and go to SC 2.4 No =Not a WHCV
SC 2.4.Has WDNR identified the wetland within the S/T/R as a Wetland of High Conservation Value and listed it on
their website?Yes =Category I No =Not a WHCV
Cat.I
SC 3.0.Bogs
Does the wetland (or any part of the unit)meet both the criteria for soils and vegetation in bogs?Use the key
below.If you answer YES you will still need to rate the wetland based on its functions.
SC 3.1.Does an area within the wetland unit have organic soil horizons,either peats or mucks,that compose 16 in or
more of the first 32 in of the soil profile?Yes –Go to SC 3.3 No –Go to SC 3.2
SC 3.2.Does an area within the wetland unit have organic soils,either peats or mucks,that are less than 16 in deep
over bedrock,or an impermeable hardpan such as clay or volcanic ash,or that are floating on top of a lake or
pond?Yes –Go to SC 3.3 No =Is not a bog
SC 3.3.Does an area with peats or mucks have more than 70%cover of mosses at ground level,AND at least a 30%
cover of plant species listed in Table 4?Yes =Is a Category I bog No –Go to SC 3.4
NOTE:If you are uncertain about the extent of mosses in the understory,you may substitute that criterion by
measuring the pH of the water that seeps into a hole dug at least 16 in deep.If the pH is less than 5.0 and the
plant species in Table 4 are present,the wetland is a bog.
SC 3.4.Is an area with peats or mucks forested (>30%cover)with Sitka spruce,subalpine fir,western red cedar,
western hemlock,lodgepole pine,quaking aspen,Engelmann spruce,or western white pine,AND any of the
species (or combination of species)listed in Table 4 provide more than 30%of the cover under the canopy ?
