Wetland Delineation Report 1 April 18, 2021
INTRODUCTION
Ecological Land Services, Inc. (ELS) was contracted by Josiah Brown, to complete a wetland
delineation and report on a 5.13-acre 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
in the Nordland area of Jefferson County, Washington (Figure 1). This report summarizes the
findings of the wetland delineation according to Jefferson County Code (JCC), Chapter 18.22:
Wetlands for delineation methodology, wetland categorization, and required buffer widths.
METHODOLOGY
The wetland delineation followed the Routine Determination Method according to the 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 Corps of Engineers 2010).
The Routine Determination Method examines 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 support 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 the U.S. Army Corps of
Engineers (USACE), as “Waters of the State” by the Washington Department of Ecology (Ecology),
and locally by Jefferson County.
Three onsite wetlands and one largely offsite wetland, hereinafter referred to as Wetlands A, B, C,
and D, were delineated on March 12, 2021. The wetlands were delineated using consecutively
numbered fluorescent flagging labeled “WETLAND DELINEATION”. 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 a
handheld Global Positioning System (GPS) unit and are shown on Figure 2.
Wetland A was delineated in 2015 because of disturbances, including clearing, excavation, and road
construction. Restoration of the wetland was not fully completed by the previous owner however,
the road and culvert were removed from the west end of Wetland A. The current owner is planting
native trees within the wetland and buffer to meet the restoration requirements of Jefferson County
and the Washington Department of Ecology. The Washington Department of Ecology confirmed
the 2015 delineation of Wetland A and the wetland boundary has changed only slightly since then.
PROPERTY 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 the end of Gybe Ho Road. It is
DCD RECEIVED 5/12/2022

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 previously cleared (Photoplate 1) (Figure 2). Soil
logs have been conducted by a septic system designer to prepare a septic system site plan for future
development.
Three wetlands were delineated onsite and one offsite. Wetland A was previously delineated by
ELS and is situated in the depressional trough across the east half of the property. A large portion
of the wetland had been previously disturbed by construction of a driveway, dredging of the south
half of the wetland, and spread of dredge spoils. The previous owner did not complete restoration,
but the driveway and culvert were removed, and current owners are planting native trees to meet
restoration requirements (Photoplate 2). Undisturbed forested wetland remains north and south of
the disturbed area and represents the historic condition of the disturbed wetland. Wetland A is a
forested depressional system with a seasonally flooded hydroperiod. Wetland B was delineated
offsite and is situated in a depressional trough southwest of the property. This wetland is present in
the legal easement to the property, which enters the southwest corner of the property (Photoplate 3).
Wetland B is a forested depressional system with a seasonally flooded hydroperiod. Wetland C was
identified and delineated onsite near the western property line, just north of Wetland B. Wetland C
extends offsite to the west and is a forested sloping system with a saturated only hydroperiod.
Wetland D was identified and delineated onsite near the northern property line, northwest of Wetland
A. Most of wetland D extends offsite to the north. Wetland D is a forested depressional system
with a seasonally flooded hydroperiod (Photoplate 4).
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. These areas appear to be old logging roads
where surface water collects for short periods during the winter (Photoplate 4).
VEGETATION
Wetlands
Prior to the disturbance, Wetland A 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 in Wetland A included red alder (Alnus rubra, FAC), salmonberry (Rubus
spectabilis, FAC), Himalayan blackberry (Rubus armeniacus, FAC), slough sedge (Carex obnupta,
OBL), soft rush (Juncus effusus, FACW), lady fern (Athyrium cyclosorum, FAC), stinging nettle
(Urtica dioica, FAC), hedge nettle (Stachys chamissonis, FACW), 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.
Wetland B is also a forested system and had a canopy layer with red alder and Pacific crab apple
(Malus fusca, FACW); salmonberry in the shrub layer; and water parsley and wood fern (Dryopteris
expansa, FACW) in the herbaceous layer.
Wetland C is a sloping forested system and had a canopy of western red cedar (Thuja plicata, FAC)
and a shrub layer of salmonberry. The herbaceous layer of Wetland C was sparse with scattered
sword ferns (Polystichum munitum, FACU).
DCD RECEIVED 5/12/2022

Wetland Delineation Report 3 April 18, 2021
Wetland D is a forested system with red alder in the canopy and salmonberry in the shrub layer. The
herbaceous layer of Wetland D was sparse.
Uplands
The upland areas of the property are composed of a mixed forest dominated by Douglas fir
(Pseudotsuga menziesii, FACU), western red cedar, cherry (Prunus emarginata, FACU), 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), Himalayan blackberry, and Oregon grape (Mahonia
nervosa, FACU). The herbaceous layer is dense where the shrub cover is sparse and is dominated
by sword fern, trailing blackberry (Rubus ursinus, FACU), large-leaf avens (Geum macrophyllum,
FAC), velvet grass (Holcus lanatus, FAC), stinging nettle, and bracken fern (Pteridium aquilinum,
FACU). Slough sedge and soft rush are present in some areas of the upland that appear to be old
logging roads but are generally not a dominant species.
The indicator status, following the scientific names, indicates the likelihood of the species 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) - occur almost always under natural conditions in wetlands.
▪ FACW (facultative wetland) - usually occur in wetlands, but occasionally found in non-
wetlands.
▪ FAC (facultative) - equally likely to occur in wetlands or non-wetlands.
▪ FACU (facultative upland) - usually occur in non-wetlands, but occasionally found in wetlands.
▪ UPL (obligate upland) - occur almost always under natural conditions in non-wetlands.
▪ NI (no indicator) - insufficient data to assign to an indicator category.
SOILS
As referenced on the U.S.D.A. Natural Resources Conservation Service (NRCS 2020) 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 2020).1
Wetland Soils
Wetland soils were sampled at 5 locations.
• Test Plots 2 and 4 were conducted within Wetland A. Test Plot 2 had an 8-inch-thick surface
layer of black (10YR 2/1) gravelly sandy loam and a subsurface layer of dark grayish brown
(10YR 4/2) gravelly sandy loam with 2 percent yellowish brown (10YR 5/6) redoximorphic
features. Test Plot 2 met hydric soil indicator Depleted Matrix (F3). Test Plot 4 had two
inches of standing water so a soil sample could not be obtained. Upon investigation there

was a hydrogen sulfide smell when the shovel was inserted into the soils meeting hydric soil
indicator Hydrogen Sulfide (A11).
• Test Plot 8 was conducted in Wetland B soils. Test Plot 8 had four inches of standing water
so a soil sample could not be obtained. Upon investigation there was a hydrogen sulfide
smell when the shovel was inserted into the soils meeting hydric soil indicator Hydrogen
Sulfide (A11).
• Test Plot 9 was conducted within Wetland C. Test Plot 9 had a 2-inch-thick surface layer of
very dark gray (10YR 3/1) gravelly sandy loam with a subsurface layer of gray (10YR 5/1)
sandy loam with 20 percent dark yellowish brown (10YR 4/6) redoximorphic features. Test
Plot 9 met hydric soil indicator Depleted Matrix (F3).
• Test Plot 14 was conducted within Wetland D. Test Plot 14 had two inches of standing water
so a soil sample could not be obtained. Upon investigation there was a hydrogen sulfide
smell when the shovel was inserted into the soils meeting hydric soil indicator Hydrogen
Sulfide (A11).
Upland Soils
Upland soils were sampled at 9 locations. Soil profiles varied greatly between plots, so are listed
below in a bulleted format:
• Test Plot 1 had an 8 inch thick surface layer that was very dark gray (10YR 3/1) gravelly
sandy loam and a subsurface layer of dark brown (10YR 3/3) gravelly sandy loam.
• Test Plot 3 had a 7 inch thick surface layer that was black (10YR 2/1) loam and a subsurface
layer of dark yellowish brown (10YR 3/6) sandy loam.
• Test Plot 5 had a mixed surface layer that was 6 inches thick with 90 percent very dark
grayish brown (10YR 3/2) and 10 percent brown (10YR 4/3) sandy loam. A 3 inch layer of
wood was found at 6 inches of depth. The subsurface layer began at 9 inches and consisted
of very dark grayish brown (10YR 3/2) gravelly sandy loam.
• Test Plot 6 had a 2 inch thick surface layer of very dark brown (10YR 2/2) gravelly sandy
loam with a subsurface layer of brown (10YR 4/3) gravelly sandy loam. A restrictive layer
was found at 12 inches of depth.
• Test Plot 7 had a 6 inch thick surface layer that was very dark grayish brown (10YR 3/2)
gravelly sandy loam. The subsurface layer was mixed with 50 percent very dark grayish
brown (10YR 3/2) and dark yellowish brown (10YR 3/6) gravelly sandy loam.
• Test Plot 10 had an 8 inch thick surface layer of very dark grayish brown (10YR 3/2) gravelly
sandy loam and a subsurface layer of dark brown (7.5YR 3/3) gravelly sandy loam with 5
percent yellowish red (5YR 4/6) redoximorphic features.
• Test Plot 11 had a 6 inch thick surface layer of dark brown (10YR 3/3) gravelly sandy loam.
A restrictive layer was located at 6 inches of depth.
• Test Plot 12 had an 8 inch thick surface layer of very dark grayish brown (10YR 3/2) gravelly
sandy loam and a subsurface layer with brown (10YR 4/3) gravelly sandy loam and 3 percent
strong brown (7.5YR 4/6) redoximorphic features.
• Test Plot 13 had a 1 inch surface layer of dark brown (10YR 3/3) gravelly sandy loam
underneath 8 inches of duff. A restrictive layer was located at 9 inches of depth.

None of the upland test plots meet hydric soil criteria because the matrix chromas were too high to
be considered hydric.
HYDROLOGY
Hydrology was observed in Wetland A as standing water, saturation to the surface, and a high water
table at 6 inches where there was not standing water. Wetland A receives water from upslope runoff,
direct precipitation, and groundwater discharge. Water leaves Wetland A through an intermittently
flowing ditch at the south end.
Hydrology was observed within Wetland B as surface water 4 inches deep and a hydrogen sulfide
odor. Wetland B receives water from upslope runoff, direct precipitation, and groundwater
discharge. Water leaves Wetland B through evapotranspiration.
Hydrology was observed within Wetland C as a high water table approximately 4 inches depth.
Wetland C receives water from direct precipitation and groundwater discharge. Water leaves
Wetland C via evapotranspiration.
Hydrology was observed within Wetland D as surface water 2 inches deep and a hydrogen sulfide
odor. Wetland D receives water from upslope runoff, direct precipitation, and ground water
discharge. Water leaves Wetland D through evapotranspiration.
Wetland hydrology indicators (e.g., saturation, water marks, or a high water table) were present at
upland Test Plot 6. Surface water was approximately 2 inches deep at this test plot, but the soils
were not hydric therefore this test plot did not meet wetland criteria.
NATIONAL WETLAND INVENTORY
The National Wetlands Inventory (NWI) map does not show wetlands on or within 300 feet of the
property (Figure 5). The findings of the ELS delineation do not agree with the NWI mapping
because wetlands were identified on and adjacent to the property.2
JEFFERSON COUNTY CRITICAL AREAS
The Jefferson County Critical Areas map (JC 2020) does not indicate the presence of wetlands on
or within 300 feet of the property (Figure 6). The ELS biologist disagrees with the JC map because
wetlands were identified on and adjacent to the property (Figure 2).
CONCLUSIONS
Wetland Categorization
Wetland A is a forested depressional system with a seasonally flooded hydroperiod. Wetland B is a
depressional system with forested with three layers Cowardin classes and a seasonally flooded
hydroperiod. The stream within Wetland B does not compose greater than 10 percent of the wetland
area and therefore is not included in the hydroperiod. Wetland C is a forested slope system with a
saturated only hydroperiod. Wetland D is a forested depressional system with a seasonally flooded
2 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.

CRITICAL AREA REGULATIONS
According to JCC, standard wetland buffers are based on wetland category, scores for habitat
functions on the rating form, and the intensity of the proposed land uses in accordance with the 2014
wetland rating system. The resulting buffers of 110 feet and 40 feet are based on moderate land use
intensity3 and moderate habitat scores. Table 2 summarizes the wetland buffers (Figure 2). A 15-
foot building and impervious setback is also required from the edge of each critical area buffer.

DEVELOPMENT PROPOSAL
The project proposes to build a single-family home with an attached garage, driveway, and a septic
system near the middle of the property (Figure 3). An 8-foot-wide walking path is proposed from
the northern property to the clearing within the subject property. The septic system is proposed
3 Residential development at less than 1 unit per acre is considered a moderate intensity land use.

north of the proposed home with the reserve drainfield proposed to the northwest of the proposed
home. The home and drainfield areas are proposed within formerly cleared upland where there is
sufficient room outside the wetland buffers.
DRIVEWAY OPTIONS
Option A: The established legal easement extends north from Gybe Ho Road along the west line
of the property directly to the south (Figure 3). The 40-foot-wide easement is partially within
Wetland B. Using the easement would require direct impacts to Wetland B including clearing the
wetland, its buffer, and filling at least a portion of the wetland. This is not a viable option because
it would have significant impacts to Wetland B and potentially Wetland C.
Option B: There is an existing road along the east line that provides access to the neighboring
property to the east from Gybe Ho Road (Figure 3). The previous property owner had installed a
culvert and driveway through Wetland A to access the subject property from the east line instead of
using the existing easement. The road across the wetland was considered a violation because permits
had not been obtained prior to the activity. The road has been removed as a result and restoration is
ongoing. However, this access point remains an option because it be proposed across the disturbed
upland buffer and wetland and would avoid new buffer and/or wetland impacts that would be
associated with Options A and C. Federal, state, and local permits for crossing the wetland with a
new road would be required as would mitigation for wetland and buffer impacts. You will need to
demonstrate that this is the only viable option for the crossing and that you cannot avoid, minimize,
or rectify the impacts before the permit and mitigation can be obtained.
Option C: This option would also utilize the same road as Option B. The current owner of the
property to the east will not allow an easement to be created on that property. The onsite construction
of the road would cross a small tip of Wetland A and would significantly disturb existing conifer
forested buffer that was not cleared by the previous owner. It would also result in a significantly
longer driveway that would introduce new impervious surfaces that could affect the wetland
overtime. This option does not appear to be viable because of the level of impact that would occur
to the onsite critical areas.
LIMITATIONS
ELS bases this report’s determinations on standard scientific methodology and best professional
judgment. In our opinion, local, state, and federal regulatory agencies should agree with our
determinations. However, the information contained in this report should be considered preliminary
and used at your own risk until it has been approved in writing by the appropriate regulatory
agencies. ELS is not responsible for the impacts of any changes in environmental standards,
practices, or regulations after the date of this report.

Photo 12 was taken from Test
Plot 6. An old logging road
created a compact layer in the soil
allowing for water to pond at this
location. Soils are not hydric,
and the vegetation is not
hydrophytic, therefore this
location is not wetland.

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, 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 except during floods?
NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1
1.1 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. 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 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 any
plants 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 from
seeps. 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 and
shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft
deep).
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 that
stream or river,
The overbank flooding occurs at least once every 2 years.
DCD RECEIVED 5/12/2022
Wetland name or number A
Wetland Rating System for Western WA: 2014 Update Rating Form – 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 not
flooding
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the
surface, 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 Depressional
7. Is the entire wetland unit 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 the
wetland unit being scored.
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 HGM 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 of depression
Depressional
Depressional + Lake Fringe Depressional
Riverine + Lake Fringe Riverine
Salt Water Tidal Fringe and any other
class of freshwater wetland
Treat as
ESTUARINE
If you are still unable to determine which of the above criteria apply to your wetland, or if you have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

HABITAT FUNCTIONS - Indicators that site functions to provide important habitat
H 1.0. Does the site have the potential to provide habitat?
H 1.1. Structure of plant community: Indicators are Cowardin classes and strata within the Forested class. Check the
Cowardin plant classes in the wetland. Up to 10 patches may be combined for each class to meet the threshold
of ¼ ac or more than 10% of the unit if it is smaller than 2.5 ac. Add the number of structures checked.
Aquatic bed 4 structures or more: points = 4
Emergent 3 structures: points = 2
Scrub-shrub (areas where shrubs have > 30% cover) 2 structures: points = 1
X Forested (areas where trees have > 30% cover) 1 structure: points = 0
If the unit has a Forested class, check if:
X The Forested class has 3 out of 5 strata (canopy, sub-canopy, shrubs, herbaceous, moss/ground-cover)
that each cover 20% within the Forested polygon
1
H 1.2. Hydroperiods
Check the types of water regimes (hydroperiods) present within the wetland. The water regime has to cover
more than 10% of the wetland or ¼ ac to count (see text for descriptions of hydroperiods).
Permanently flooded or inundated 4 or more types present: points = 3
X Seasonally flooded or inundated 3 types present: points = 2
Occasionally flooded or inundated 2 types present: points = 1
Saturated only 1 type present: points = 0

H 1.3. Richness of plant species
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 and 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
5 - 19 species points = 1
< 5 species points = 0

http://wdfw.wa.gov/conservation/phs/list/)
Count how many of the following priority habitats are within 330 ft (100 m) of the wetland unit: NOTE: This question is
independent of the land use between the wetland unit and the priority habitat.
⎯ Aspen Stands: Pure or mixed stands of aspen greater than 1 ac (0.4 ha). ⎯ Biodiversity Areas and Corridors: Areas of habitat that are relatively important to various species of native fish and
wildlife (full descriptions in WDFW PHS report).

layered canopy with occasional small openings; with at least 8 trees/ac (20 trees/ha ) > 32 in (81 cm) dbh or > 200
years of age. Mature forests – Stands with average diameters exceeding 21 in (53 cm) dbh; crown cover may be less
than 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally less than that
found in old-growth; 80-200 years old west of the Cascade crest.
⎯ Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak component is important (full descriptions in WDFW PHS report p. 158 – see web link above). ⎯ Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and
terrestrial ecosystems which mutually influence each other. ⎯ Westside Prairies: Herbaceous, non-forested plant communities that can either take the form of a dry prairie or a wet
prairie (full descriptions in WDFW PHS report p. 161 – see web link above).
⎯ Instream: The combination of physical, biological, and chemical processes and conditions that interact to provide functional life history requirements for instream fish and wildlife resources.
⎯ Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and
Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report –
see web link on previous page).
⎯ Caves: A naturally occurring cavity, recess, void, or system of interconnected passages under the earth in soils, rock, ice, or other geological formations and is large enough to contain a human.
⎯ Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation. ⎯ Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite,
and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs.
⎯ Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to
enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western
Washington and are > 6.5 ft (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft
(6 m) long.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are addressed
elsewhere.

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, 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 except during floods?
NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1
1.1 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. 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 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 any
plants 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 from
seeps. 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 and
shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft
deep).
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 that
stream or river,
The overbank flooding occurs at least once every 2 years.

Wetland name or number B
Wetland Rating System for Western WA: 2014 Update Rating Form – 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 not
flooding
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the
surface, 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 Depressional
7. Is the entire wetland unit 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 the
wetland unit being scored.
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 HGM 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 of depression
Depressional
Depressional + Lake Fringe Depressional
Riverine + Lake Fringe Riverine
Salt Water Tidal Fringe and any other
class of freshwater wetland
Treat as
ESTUARINE
If you are still unable to determine which of the above criteria apply to your wetland, or if you have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.

These questions apply to wetlands of all HGM classes.
HABITAT FUNCTIONS - Indicators that site functions to provide important habitat
H 1.0. Does the site have the potential to provide habitat?
H 1.1. Structure of plant community: Indicators are Cowardin classes and strata within the Forested class. Check the
Cowardin plant classes in the wetland. Up to 10 patches may be combined for each class to meet the threshold
of ¼ ac or more than 10% of the unit if it is smaller than 2.5 ac. Add the number of structures checked.
Aquatic bed 4 structures or more: points = 4
Emergent 3 structures: points = 2
Scrub-shrub (areas where shrubs have > 30% cover) 2 structures: points = 1
X Forested (areas where trees have > 30% cover) 1 structure: points = 0
If the unit has a Forested class, check if:
X The Forested class has 3 out of 5 strata (canopy, sub-canopy, shrubs, herbaceous, moss/ground-cover)
that each cover 20% within the Forested polygon
1
H 1.2. Hydroperiods
Check the types of water regimes (hydroperiods) present within the wetland. The water regime has to cover
more than 10% of the wetland or ¼ ac to count (see text for descriptions of hydroperiods).
Permanently flooded or inundated 4 or more types present: points = 3
X Seasonally flooded or inundated 3 types present: points = 2
Occasionally flooded or inundated 2 types present: points = 1
Saturated only 1 type present: points = 0
Permanently flowing stream or river in, or adjacent to, the wetland
Seasonally flowing stream in, or adjacent to, the wetland
Lake Fringe wetland 2 points
Freshwater tidal wetland 2 points
0
H 1.3. Richness of plant species
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 and 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
5 - 19 species points = 1
< 5 species points = 0

H 1.4. Interspersion of habitats
Decide from the diagrams below whether interspersion among Cowardin plants classes (described in H 1.1), or
the classes and unvegetated areas (can include open water or mudflats) is high, moderate, low, or none. If you
have four or more plant classes or three classes and open water, the rating is always high.
None = 0 points Low = 1 point Moderate = 2 points

⎯ Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation. ⎯ Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite,
and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs.
⎯ Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to
enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western
Washington and are > 6.5 ft (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft
(6 m) long.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are addressed
elsewhere.

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, 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 except during floods?
NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1
1.1 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. 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 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 any
plants 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?
X The wetland is on a slope (slope can be very gradual),
X 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, X 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 and
shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft
deep).
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 that
stream or river, The overbank flooding occurs at least once every 2 years.
DCD RECEIVED 5/12/2022
Wetland name or number C
Wetland Rating System for Western WA: 2014 Update Rating Form – 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 not
flooding
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the
surface, 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 Depressional
7. Is the entire wetland unit 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 the
wetland unit being scored.
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 HGM class listed in column 2

HABITAT FUNCTIONS - Indicators that site functions to provide important habitat
H 1.0. Does the site have the potential to provide habitat?
H 1.1. Structure of plant community: Indicators are Cowardin classes and strata within the Forested class. Check the
Cowardin plant classes in the wetland. Up to 10 patches may be combined for each class to meet the threshold
of ¼ ac or more than 10% of the unit if it is smaller than 2.5 ac. Add the number of structures checked.
Aquatic bed 4 structures or more: points = 4
Emergent 3 structures: points = 2
Scrub-shrub (areas where shrubs have > 30% cover) 2 structures: points = 1
X Forested (areas where trees have > 30% cover) 1 structure: points = 0
If the unit has a Forested class, check if:
X The Forested class has 3 out of 5 strata (canopy, sub-canopy, shrubs, herbaceous, moss/ground-cover)
that each cover 20% within the Forested polygon

⎯ Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation. ⎯ Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite,
and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs.
⎯ Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to
enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western
Washington and are > 6.5 ft (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft
(6 m) long.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are addressed
elsewhere.

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, 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 except during floods?
NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1
1.1 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. 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 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 any
plants 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 from
seeps. 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 and
shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft
deep).
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 that
stream or river,
The overbank flooding occurs at least once every 2 years.

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 not
flooding
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the
surface, 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 Depressional
7. Is the entire wetland unit 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 the
wetland unit being scored.
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 HGM 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.

If you are still unable to determine which of the above criteria apply to your wetland, or if you have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.
