IRON MOUNTAIN QUARRY WETLAND INVENTORY UPDATE (BGE19_0170.020)
INTRODUCTION
An objective review of 22 wetland boundaries within the Iron Mountain New Shine Quarry (NSQ)
was completed for MDNS conditional requirements of approval for the current mining operation.
NSQ is beginning Phase 2 which requires an update to the wetland boundaries for support and
development of the Final Wetland Mitigation Plan. The investigation was semi-quantitative in
which wetland determination was confirmed. Wetland flagging was verified where present and
boundaries approximated for consistency to the New Shine Quarry Wetland Delineation and
Inventory, July 2009, and Addendum, June 2011. These documents are further referenced in this
report as 2009 Report. Where confirmed the observed wetland boundary was evaluated
objectively as having no change, larger, smaller, or non wetland. Assessment data was taken for
determination of function, value and category rating fo r processing wetland category to the
current guidance using the Western Washington Wetland Rating System-2014 by the
Department of Ecology (Ecology).
The scope of this report entails the findings of the 2019 wetland review by BGE Environmental,
LLC for all NSQ wetlands. The 2020 wetland review concludes that Wetland F is non wetland
where hydrophyte coverage is limited to individuals and hydrology was absent. Wetland S is
larger. All other subject wetlands are unchanged.
This wetland inventory provides an inventory of the 2019 findings prepared to satisfy JCC Title
18.22.960 and includes the following:
• Site description and area of assessment;
• Background research and identification of potentially regulated critical areas, wetland
and surface waters, in the vicinity of the proposed project;
• Wetland findings, review, and summary;
• Determination Forms ; and
• Category Rating update using the 2014 Ecology guidance.

IRON MOUNTAIN QUARRY WETLAND INVENTORY UPDATE (BGE19_0170.020)
METHODS
Resource information in the public-domain was reviewed for this delineation. Data researched
included relevant mapping from U.S. Fish and Wildlife Service, Washington State Department of
Fish and Wildlife (WDFW), and Washington Department of Natural Resour ces (WDNR) Natural
Heritage Database, and the Kitsap County GIS mapping resource. Reference sources are
summarized in Appendix A.
The wetlands and surface waters were objectively reviewed and assessed in March 2019 by a
Senior Professional Wetland Scientis t (SPWS). All wetlands were relocated with plan maps and
confirmed with remnant flagging based on the 2009 delineation by Environ. Wetland flagging
was frequently encountered. Where absent, the boundary was field walked and confirmed for
accuracy to the projects plan maps (survey).
Wetland determinations were completed for all subject wetlands on August 24, 25, and 26, 2020.
The findings of determination are provided in Appendix B. Wetlands were confirmed using the
Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western
Mountains, Valleys, and Coast Region. Wetland Regulatory Assistance Program, Army Corps of
Engineer. May 2010.
Delineated wetlands were classified using the Western Washington Wetland Rating System -2014
by the Department of Ecology (Ecology). Wetland ratings are provided in Appendix C. Category
ratings were used to determine and identify standard buffer widths using JCC Title Table
18.22.730(1)(a).

BACKGROUND INFORMATION
RESEARCH AND DATA SYNTHESIS
Background research and data review are essential for the assessment wetlands, surface waters
and documented habitat and species within the vicinity of the project site. Data researched
included relevant mapping from U.S. Fish and Wildlife Service, Natural Resources Conservation
Service Web Soil Survey, Washington State Department of Fish and Wildlife (WDFW),
Washington Department of Ecology, and Washington Department of Natural Resources (WDNR)
Natural Heritage Database.
U.S. FISH & WILDLIFE SERVICE NATIONAL WETLAND INVENTORY (NWI)
The US Fish and Wildlife Service National Wetland Inventory indicates no wetlands within the
general boundaries of the lease area with the exception to a freshwater pond near the southeast
corner. A forested complex is shown to the west of the investigation area, aligned to the Shine
Quarry. Three surface waters are delineated to the area; two intermittent and one unknow n
perennial.
NATURAL RESOURCES CONSERVATION SERVICE WEB SOIL SURVEY
Multiple soil series are mapped within the lease area. A Jefferson County Soil Map and
supporting legend and series unit descriptions is provided in Appendix A.
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 the vicinity of the project area.
WDFW PRIORITY SPECIES AND HABITAT (PHS)
The Washington Department of Fish and Wildlife Priority Habitats and Species database has no
documented resources to the parcel. Shine Creek is documented as supporting occurrences,
migration, and breeding for coho (Oncorthynchus kisutch), cutthroat (Oncorhynchus clarki),
winger steelhead (Oncorhynchus mykiss), and resident coastal cutthroat.

IRON MOUNTAIN QUARRY WETLAND INVENTORY UPDATE (BGE19_0170.020)
PROJECT SUMMARY AND SCOPE
The Iron Mountain Quarry is located within 142 acres of leased land under the ownership of
Pope Resources. It is bound within two par cels with tax parcel numbers 821302001 and
821291002. The site is located on the north side of SR -104/SR-19 intersection in unincorporated
Jefferson County. Regional setting is Section 29, Township 28 N, Range 01 E, W.M.
The quarry is identified as the approved facilities and uses which include the New Shine Quarry
mining areas, Shine Quarry processors, stormwater ponds, and office. The NSQ is approved as
two Phases 1 and 2, with conditions per a Mitigated Determination of Non -significance (MDNS)
by Jefferson County.
Phase 1 approval included areas 1A mining and 1B operations. To date Phase 1A is being mined
and Phase 1B was partially implemented for stockpiles. Processing operations were
implemented to the existing adjacent Shine Quarry instead.
Phase 2 is currently posed for final approval with storm water applications and critical area
review and status for satisfying the conditions of approval. The SEPA MDNS #16 requires that all
onsite wetlands that have the potential to be indirectly affected by the project activity shall be
re-delineated before “Phase 2” commences. Both the boundaries shall be confirmed by the
County and/or the U.S. Army Corps of Engineers. The prior approved jurisdiction determination
is expired (July 25, 2016) and therefore the project is seeking a JD (NWS-2020-156) for
consistency to move forward with Phase 2.
Known and predicted impacts shall be re-evaluated to the Final Phase 1B & 1A Wetland
Mitigation Plan (ENVIRON dated May 2012) for conformance to the applied mitigation to ensure
that the goals and standards have been satisfied. The Final Wetland Mitigation plan may include
on- and off-site mitigation cumulative for all mining Phases 1B, 1A, and Phase 2.

FINDINGS
WETLAND REVIEW
The subject parcel was assessed over multiple days in mid to late March 2019 and again in
August 2020. Characterization of climatic conditions for precipitation in the Wetland
Determination Data Forms were determined using the WETS table methodology (USDA, NRCS
2015). The “Chimacum 4 S” station from 1971-2000 was used as a source for precipitation data
(http://agacis.rcc-acis.org/). The WETS table methodology uses climate data from the three
months prior to the site visit month to determine if normal conditions are present in the study
area region.
WETLANDS
All wetlands were relocated and assessed for jurisdiction and category rating. Boundary review
was replicated if flags were present or objectively considered if flags were absent. Most of the
wetlands had HGM classifications of depressional and sloped. One wetland, WD, was assessed
for rating purposes only, as a riverine complex. This wetland is nearly exclusively off-site to the
south east. Sample plots were deferred to the 2009 Report due to proximity of the project
action area to the wetland location.
All relocated wetlands were present under previously documented m ostly evergreen forested
conditions. No direct wetland impacts have occurred with the implementation of Phase 1A. The
exception is a set of wetland areas term Quarry wetlands and are within the area of active
mining to Phase 1A.
Wetlands were field reviewed and assessed for jurisdiction, boundary, and category. Vegetation
inventory included red alder (Alnus Rubra, FAC), Western red cedar (Thuja plicata, FAC),
Wes tern hemlock (Tsuga heterophylla, FACU), Pacific willow (Salix Iucida, FACW), cascara
(Frangula purshiana, FAC), spiraea (Spiraea douglasii, FACW), salmonberry (Rubus spectabilis,
FAC), Henderson's sedge (Carex hendersonii, OBL), lady fern (Athyrium cuclosorum, FAC), sword
fern (Polystichum munitum, FACU), and Himalayan blackberry (Rubus armeniacus, FAC).
Soils varied among wetlands and within sub basins. The most common hydric soil indicator was
redox dark surface, mostly along the sloped wetland areas. Within the deeper depressional
complexes, histosols, loamy mucky mineral soils, and depleted below dark surface conditions
were documented.

IRON MOUNTAIN QUARRY WETLAND INVENTORY UPDATE (BGE19_0170.020)
Wetland boundaries were reviewed, not delineated, in March 2019 in which hydrology was
commonly observed as inundation or saturation. The determination via sample plots occurre d in
August 2020 where hydrologic conditions were documented and confirmed more consistently
with secondary indicators due to summer dry conditions. Hydrologic conditions were noted or
applied as professional judgement, when deemed necessary, from the obs ervations in 2019.
Wetlands are assigned a numeric score based on the combined scores for site, landscape
potential and for society value. The numeric score determines the category rating of the wetland.
The Jefferson County Code (JCC) then uses the rating for the determination of standard buffer
widths, mitigation requirements, and permitted uses in the wetland. To satisfy the wetland
inventory update, all wetlands were rated to the 2014 Update, Western Washington Wetland
Rating System. A summary of the 2019 determination is provided below.

Summaries of all wetlands are provided at the end of this report. The summaries include the
facts and findings determinations and comparisons of the 20 09 and 2020 NSQ wetlands.
Determination Forms (August 2020) are provided in Appendix B and 2019 Rating forms in
Appendix C.
NON WETLAND
The non-wetland portions of the property outside of the quarry facilities are dominant
evergreens with variable densities of strata. Species typical included Douglas fir (Pseudotsuga
menziesii, FACU). Western red cedar, Western hemlock, Indian plum (Oemleria cerasiformis,
UPL), red elderberry (Sambucus racemose, UPL), stinging nettle (Urtica dioica. FAC), sword fern,
salal (Gaultheria shallon, FACU), dull Oregon grape (Mahonia nervosa, FACU), evergreen
huckleberry (Vaccinium ovatum, FACU), red huckleberry (V. parvifolium, FACU), and English
holly (Ilex aquifolium, FACU).
Upland soils tended to be too dry during the sampling period to retain profiles for consistency.
Commonly, the excavated minerals were wetted to obtain Munsell accuracy for Hue and Value.
Shovel refusal was also frequently encountered within the upper te n inches. The absence of
hydrology was confirmed.

REGULATORY REQUIREMENTS
Wetland buffers are based on three factors: the wetland category, the wetland habitat score, and the
impact of proposed land use intensity. All buffers shall be measured horizontally from a perpendicular
line established at the wetland edge. Buffer widths may be reduced through the implementation of
impact-reduction measures or upon submission of wetland evaluation by a wetland specialist that
demonstrates the reduction does not adversely affect the existing functions and values of the wetland.
Reductions include the implementation of averaging. Mitigation sequencing applies for reasonable
analysis to avoid and minimize impacts before mitigating. The following table is a summary of all wetland
ratings and standard buffer provisions.

IRON MOUNTAIN QUARRY WETLAND INVENTORY UPDATE (BGE19_0170.020)
It should be noted that the Hruby (2004b) wetland rating methods indicates in the annotated version of
the rating system that the rating system for wetland s smaller than 4,356 sq ft (0.1 acre) “will not work
well”. As many of the site wetlands are less than 0.1 acre, the related scores appeared to overestimate
the potential function. With the updated 2014 version of the rating system, most of these small wetlands
resulted in Category IV system, as theorized and projected by ENVIRON.

distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more

This information only documents the location of fish and wildlife resources to the best of our knowledge. It is not a complete inventory and it is important to note that fishand wildlife resources may occur in areas not currently known to WDFW biologists, or in areas for which comprehensive surveys have not been conducted. Site specific surveys are frequently necesssary to rule out thepresence of priority resources. Locations of fish and wildlife resources are subject to vraition caused by disturbance, changes in season and weather, and other factors.

Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - January 14, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).
HGM Classification of Wetland in Western Washington
If 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.
Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 3 WSDOT Adapted Form - January 14, 2015
Wetland name or number
NO - go to 7 YES - The wetland class is Depressional
NO - go to 8 YES - The wetland class is Depressional
Slope + Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional + Lake Fringe
Riverine + Lake Fringe
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.
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.
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.
Treat as
ESTUARINE
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
Slope + Riverine
Slope + Depressional
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.

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.
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 ).
Old-growth/Mature forests: Old-growth west of Cascade crest – Stands of at least 2 tree species,
forming a multi-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 ).
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.
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.
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.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are
addressed elsewhere.

Has the WA Department of Natural Resources updated their website to include the list
of Wetlands of High Conservation Value?
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 .
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?

Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - January 14, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).
HGM Classification of Wetland in Western Washington
If 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.

NO - go to 8 YES - The wetland class is Depressional
Slope + Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional + Lake Fringe
Riverine + Lake Fringe
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.
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.
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.
Treat as
ESTUARINE
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
Slope + Riverine
Slope + Depressional
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.

WDFW Priority Habitats
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.
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 ).
Old-growth/Mature forests: Old-growth west of Cascade crest – Stands of at least 2 tree species,
forming a multi-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.

Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - January 14, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).
HGM Classification of Wetland in Western Washington
If 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.
Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 3 WSDOT Adapted Form - January 14, 2015
Wetland name or number
NO - go to 7 YES - The wetland class is Depressional
NO - go to 8 YES - The wetland class is Depressional
Slope + Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional + Lake Fringe
Riverine + Lake Fringe
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.
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.
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.
Treat as
ESTUARINE
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
Slope + Riverine
Slope + Depressional
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.

Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).
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.
If 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.
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
HGM Classification of Wetland in Western Washington
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;
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.
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).

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.
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.
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.
HGM classes within the wetland unit
Wetland rating determination concluded with original findings and limited observations as much of the wetland
area is located outside of the project area. No Figures provided with rating due to location and proximity to
action 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.

Has WDNR identified the wetland within the S/T/R as a Wetland of High Conservation
Value and listed it on their website?
Has the WA Department of Natural Resources updated their website to include the list
of Wetlands of High Conservation Value?
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 .
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?
Does an area within the wetland unit have organic soils, either peats or mucks, that are

ash, or that are floating on top of a lake or pond?
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?
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.

Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - January 14, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).
HGM Classification of Wetland in Western Washington
If 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.

Rating Form - Effective January 1, 2015 3 WSDOT Adapted Form - January 14, 2015
Wetland name or number
NO - go to 7 YES - The wetland class is Depressional
NO - go to 8 YES - The wetland class is Depressional
Slope + Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional + Lake Fringe
Riverine + Lake Fringe
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.
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.
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.
Treat as
ESTUARINE
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
Slope + Riverine
Slope + Depressional
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.

of Wetlands of High Conservation Value?
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 .
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?

Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - January 14, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).
HGM Classification of Wetland in Western Washington
If 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.
Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 3 WSDOT Adapted Form - January 14, 2015
Wetland name or number
NO - go to 7 YES - The wetland class is Depressional
NO - go to 8 YES - The wetland class is Depressional
Slope + Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional + Lake Fringe
Riverine + Lake Fringe
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.
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.
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.
Treat as
ESTUARINE
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
Slope + Riverine
Slope + Depressional
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.

Old-growth/Mature forests: Old-growth west of Cascade crest – Stands of at least 2 tree species,
forming a multi-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.

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 ).
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.
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.
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.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are

Has WDNR identified the wetland within the S/T/R as a Wetland of High Conservation
Value and listed it on their website?
Has the WA Department of Natural Resources updated their website to include the list
of Wetlands of High Conservation Value?
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 .
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?
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?
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?
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.
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?
CATEGORIZATION BASED ON SPECIAL CHARACTERISTICS
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?
The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing,

Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - January 14, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).
HGM Classification of Wetland in Western Washington
If 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.
Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 3 WSDOT Adapted Form - January 14, 2015
Wetland name or number
NO - go to 7 YES - The wetland class is Depressional
NO - go to 8 YES - The wetland class is Depressional
Slope + Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional + Lake Fringe
Riverine + Lake Fringe
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.
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.
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.
Treat as
ESTUARINE
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
Slope + Riverine
Slope + Depressional
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.

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.
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.
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.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are
addressed elsewhere.

Has the WA Department of Natural Resources updated their website to include the list
of Wetlands of High Conservation Value?
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 .
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?

Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - March 2, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
If 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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).
HGM Classification of Wetland in Western Washington
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.

Rating Form - Effective January 1, 2015 3 WSDOT Adapted Form - March 2, 2015
Wetland name or number
NO - go to 7 YES - The wetland class is Depressional
NO - go to 8 YES - The wetland class is Depressional
NOTES and FIELD OBSERVATIONS:
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.
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.
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.
Riverine
Treat as
ESTUARINE
Slope + Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional + Lake Fringe
Riverine + Lake Fringe
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.

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.
These questions apply to wetlands of all HGM classes.
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
2
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.

Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - March 2, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
If 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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).
HGM Classification of Wetland in Western Washington
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 3 WSDOT Adapted Form - March 2, 2015
Wetland name or number
NO - go to 7 YES - The wetland class is Depressional
NO - go to 8 YES - The wetland class is Depressional
NOTES and FIELD OBSERVATIONS:
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.
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.
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.
Riverine
Treat as
ESTUARINE
Slope + Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional + Lake Fringe
Riverine + Lake Fringe
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.

Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - March 2, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
HGM Classification of Wetland in Western Washington
If 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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).

class of freshwater wetland
HGM class to
use in rating
Riverine
Depressional
Lake Fringe
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.
Riverine
Treat as
ESTUARINE
Slope + Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional + Lake Fringe
Riverine + Lake Fringe
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
Slope + Riverine
Slope + Depressional
Depressional
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.
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.
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.

Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - March 2, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
HGM Classification of Wetland in Western Washington
If 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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).

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.
Riverine
Treat as

Depressional + Lake Fringe
Riverine + Lake Fringe
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

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.
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.
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.

Has the WA Department of Natural Resources updated their website to include the list
of Wetlands of High Conservation Value?
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 .
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?
Does an area within the wetland unit have organic soils, either peats or mucks, that are

level, AND at least a 30% cover of plant species listed in Table 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.

Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - March 2, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
HGM Classification of Wetland in Western Washington
If 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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).

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.
Riverine
Treat as

Slope + Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional + Lake Fringe
Riverine + Lake Fringe
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

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.
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.
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.

not have to name the species. Do not include Eurasian milfoil, reed canarygrass, purple
loosestrife, Canadian thistle 1
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.

Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - March 2, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
HGM Classification of Wetland in Western Washington
If 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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).

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

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.
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.
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.

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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
HGM Classification of Wetland in Western Washington
If 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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).

Depressional + Lake Fringe
Riverine + Lake Fringe
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.

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.
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.
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.

Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - March 2, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
HGM Classification of Wetland in Western Washington
If 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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).

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.
Riverine
Treat as
ESTUARINE
Slope + Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional + Lake Fringe
Riverine + Lake Fringe
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

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.
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.
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.

Has the WA Department of Natural Resources updated their website to include the list
of Wetlands of High Conservation Value?
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 .
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?
Does an area within the wetland unit have organic soils, either peats or mucks, that are

level, AND at least a 30% cover of plant species listed in Table 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.

Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - March 2, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
HGM Classification of Wetland in Western Washington
If 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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).

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.
Riverine
Treat as

Depressional + Lake Fringe
Riverine + Lake Fringe
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

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.
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.
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.

Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - March 2, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
HGM Classification of Wetland in Western Washington
If 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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).

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.

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.
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.
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 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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
HGM Classification of Wetland in Western Washington
If 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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).

Depressional + Lake Fringe
Riverine + Lake Fringe
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.

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.
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.
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.

Wetland Rating System for Western WA: 2014 Update
Rating Form - Effective January 1, 2015 2 WSDOT Adapted Form - March 2, 2015
Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
HGM Classification of Wetland in Western Washington
If 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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).

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.
Riverine
Treat as
ESTUARINE
Slope + Lake Fringe
Depressional + Riverine along stream
within boundary of depression
Depressional + Lake Fringe
Riverine + Lake Fringe
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
Slope + Riverine
Slope + Depressional

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.
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.
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.

Has the WA Department of Natural Resources updated their website to include the list
of Wetlands of High Conservation Value?
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 .
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?
Does an area within the wetland unit have organic soils, either peats or mucks, that are

ash, or that are floating on top of a lake or pond?
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?
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.

Wetland name or number
For questions 1 -7, the criteria described must apply to the entire unit being rated.
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
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?
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 leaves the wetland without being impounded.
NO - go to 5 YES - The wetland class is Slope
5. Does the entire wetland unit meet all of the following criteria?
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.
If 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.
HGM Classification of Wetland in Western Washington
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.
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;
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.
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).
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding
from that stream or river,
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.
At least 30% of the open water area is deeper than 6.6 ft (2 m).

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.
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.
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.
Treat as
Slope + Lake Fringe
Depressional + Riverine along stream

Wetland name or number
Aspen Stands: Pure or mixed stands of aspen greater than 1 ac (0.4 ha).
Herbaceous Balds: Variable size patches of grass and forbs on shallow soils over bedrock.
Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation.
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 ).
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.
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.
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.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are
addressed elsewhere.
Old-growth/Mature forests: Old-growth west of Cascade crest – Stands of at least 2 tree species,
forming a multi-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.
WDFW Priority Habitats
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.
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 ).

CATEGORIZATION BASED ON SPECIAL CHARACTERISTICS
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?
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.
Has WDNR identified the wetland within the S/T/R as a Wetland of High Conservation
Value and listed it on their website?
Has the WA Department of Natural Resources updated their website to include the list
of Wetlands of High Conservation Value?
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 .
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?
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?
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?
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.
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?

Does the wetland have at least 1 contiguous acre of forest that meets one of these
criteria for the WA Department of Fish and Wildlife’s forests as priority habitats? If you
answer YES you will still need to rate the wetland based on its functions.
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.
Is the wetland west of the 1889 line (also called the Western Boundary of Upland
Ownership or WBUO)? If you answer yes you will still need to rate the wetland
based on its habitat functions.
Is the wetland 1 ac or larger and scores an 8 or 9 for the habitat functions on the form
(rates H,H,H or H,H,M for the three aspects of function)?
Is the unit between 0.1 and 1 ac, or is it in a mosaic of wetlands that is between 0.1 and
1 ac?
