The site consists of an irregular shaped parcel with a total area of 1.93
acres and located within the SW ¼ of Section 11, Township 23 North,
Range 5 East of the W.M. The site is a mix of undeveloped forested area,
old pasture and disturbed areas.
METHODOLOGY
Ed Sewall of Sewall Wetland Consulting, Inc. inspected the site between
February 11 and April 22 of 2025.
The site was reviewed using methodology described in the Washington
State Wetlands Identification Manual (WADOE, March 1997). This is the
methodology currently recognized by the City of Renton and the State of
Ultima/#25-103
Sewall Wetland Consulting, Inc.
May 20, 2025

Washington for wetland determinations and delineations. The site was
also inspected using the methodology described in the Corps of Engineers
Wetlands Delineation Manual (Environmental Laboratory, 1987), and the
Western Mountains, Valleys and Coast region Supplement (Version 2.0)
dated June 24, 2010, as required by the US Army Corps of Engineers.
Soil colors were identified using the 1990 Edited and Revised Edition of
the Munsell Soil Color Charts (Kollmorgen Instruments Corp. 1990).
Wetlands in Maple Valley are rated using the 2014 Washington State
Department of Ecology Washington State Wetland Rating System for
Western Washington, 2014 Update, dated June 2014 Publication No. 14-
06-018.
The ordinary high water mark (OHWM) of any streams was located based
upon the criteria described in the Washington Department of Ecology draft
publication Determining The Ordinary High Water Mark on Streams In
Washington State (WADOE Publication 08-06-001, March 2008).
Hydrology Monitoring
The hydrology of the site was monitored through the early growing
season using 15 monitoring wells placed throughout the site. The wells
were inspected weekly through the late winter and early growing season
to determine what, if any parts of the site met wetland hydrology criteria.
OBSERVATIONS
Existing Site Documentation.
Prior to visiting the site, a review of several natural resource inventory
maps was conducted. Resources reviewed included the King County
iMap website, City of Renton Critical Area Mapping, National Wetland
Inventory Map and the NRCS Soil Survey online mapping and Data, the
WADNR Fpars stream mapping website and the WDFW Priority Habitats
and species maps website. In addition, the 2010 Critical Area Study and
mitigation plan by Sewall Wetland Consulting, Inc. for the Olympus Villa
development south of the site was reviewed.

Altman-Oliver Reconnaissance Mapping
A previous reconnaissance type study of the site by Altman-Oliver at an
unknown date identified two potential wetland areas on the site. It
appears this determination was done from a single site visit with no
hydrologic monitoring, nor were these areas flagged.

Olympus Villa Critical Area Study-Sewall Wetland Consulting, Inc.
December 2010.
A Critical Area study and associated mitigation plan were prepared by
Sewall Wetland Consulting for the Olympus Villa subdivision
immediately south of the site in 2010. This was reviewed and approved
as part of the subdivision by the City. The study found two wetlands on
the site to the south, one of which is to the southeast of the site and was
called a Category 2 wetland under an old rating system with an
associated 50’ buffer. This wetland was at its closest point 105’ from the
southeast corner of the site.

Field observations
As previously stated the site is a mix of deciduous forest and disturbed
areas. The overstory is generally a mix of big leaf maple, black
cottonwoods, bitter cherry, red alder and scattered mountain ash and
apple trees to the west.
The understory consists of thickets of Himalayan blackberry, sword fern,
Indian plum, vine maple and in disturbed areas some soft rush. The
western side of the site is a fallow pasture area vegetated with a mix of
pasture grasses and scotch broom. This area contains a garden on the
Ultima/#25-103
Sewall Wetland Consulting, Inc.
May 20, 2025
Page 11
south side of the pasture area. The site is surrounded by single family
homes to the north, south west and west.
Soil pits excavated in the majority of the site consist of high chroma
gravelly loam soils which do not meet hydric soil criteria.
As two potential wetland areas were previously identified on the site, a
total of 15 groundwater monitoring wells were located across the site in
low spots and areas identified in the Altman Oliver reconnaissance
mapping. These were placed on January 14, 2025 and were monitored
weekly from February 11 – April 24 2025 to determine what if any of the
site contained saturated or inundated soils long enough to meet wetland
hydrology criteria as identified in the Corps Manual.

Following the hydrologic monitoring of the site through the early growing
season it was found that two small areas meet wetland criteria. These
areas were in the locations of wells #4,#8 & #9. Below is a description of
these areas;
Wetland A
Wetland A consists of a small (522sf), disturbed area on the southeast
corner of the site that is partially within an old excavated ditch and
abuts a gravel driveway to the east. This wetland was flagged with pink
wire flagging labeled A1-A6.
The wetland is vegetated with a mix of reed canary grass, soft rush,
creeping buttercup and some hardhack.
Soil pits excavated within the wetland revealed a silty loam with a B-
horizon soil color of 10YR 2/1 with few, fine faint redoximorphic
concentrations. Soils within this area remained saturated within 9”-12”
of the surface in the early growing season (march). This area was
observed to be saturated to the surface during our non -growing season
winter observations of the site.
Using the 2014 WADOE Wetland Rating system (2023 updated form)
and rating the wetland as a depressional type wetland, this wetland
scored a total of 14 points with 3 for habitat which indicates a Category
IV wetland.
According to City of Renton Municipal Code 4-3-050G.2, Category IV
wetlands with a land use such as a subdivision have a 50’ buffer
measured from the wetland edge.
Wetland B
Wetland B consists of a small (469sf), depression near the north edge of
the site on the western side. It appears uncontrolled roof runoff from the
garage building to the north may contribute to this area.
This small wetland was flagged with pink wire flags labeled B1-B6. The
wetland is a partially bare depression with some sedge, dagger leaf rush,
creeping buttercup and Watsons willow herb.
Ultima/#25-103

Soil pits excavated within the wetland revealed a silty loam with a B-
horizon soil color of 10YR 2/2 with few, fine faint redoximorphic
concentrations. Soils within this area remained saturated within 10”-12”
of the surface in the early growing season (march). This area was
observed to be saturated to the surface during our non -growing season
winter observations of the site.
Using the 2014 WADOE Wetland Rating system (2023 updated form)
and rating the wetland as a depressional type wetland, this wetland
scored a total of 13 points with 3 for habitat which indicates a Category
IV wetland.
According to City of Renton Municipal Code 4-3-050G.2, Category IV
wetlands with a land use such as a subdivision have a 50’ buffer
measured from the wetland edge.
Off-site Wetland
As previously discussed, there is a forested wetland to the southeast of the
site. The following is a description of the wetland from the December 16,
2010 Critical Area Study for Olympus Villa;
This depressional type wetland is heavily overgrown wit h blackberry and contains a
deciduous overstory canopy approximately 50 years in age. The wetland sits in a
shallow depression that has an old dug ditch at the north end of the wetland near flag
A11. It is unknown if water actually drains in or out this ditch as it has been dry during
Ultima/#25-103
Sewall Wetland Consulting, Inc.
May 20, 2025
Page 14
our site visits. There was no evidence that any flow occurred in this ditch, although in
the winter it is feasible it does drain to some degree.
Above: Looking north at the east end of the site where Wetland A is loca ted.
Vegetation in this wetland consists of an overstory of red alder that is 6”-18”dbh, with
an understory comprised of vine maple (Acer circinatum), red -osier dogwood (Cornus
stolinifera), salmonberry (Rubus spectabilis), and a substantial amount of Him alayan
blackberry. The herb strata is sparse due to the heavy blackberry cover, but consists of
patches of slough sedge (Carex obnupta), creeping buttercup (Ranunculus repens), lady
fern (Athyrium filix-femina) and some manna grass (Glyceria elata).
Soil pits excavated within the wetland revealed a sandy loam with a matrix color of 10YR
2/2 with few, fine redoximoprhic concentrations. Soils were only moist during our dry
season site inspection, but water stained leaves and water marks on vegetation in dicate
standing water is present within this wetland during the wet season.
This wetland would be classified as PFO1E (palustrine, forested, broad leaved
deciduous, persistent, saturated) according to the US Fish and Wildlife Wetland
Classification methodology (Cowardin et al. 1979).

According to the criteria in City of Renton Municipal Code (RMC) Chapter 4 -3-050.M.1,
This wetland would be classified as Category 2 wetland. Category 2 wetlands are
defined in the Code as follows;
ii. Category 2: Category 2 wetlands are wetlands which meet one or more
of the following criteria:
(a) Wetlands that are not Category 1 or 3 wetlands; and/or
(b) Wetlands that have heron rookeries or osprey nests, but are not
Category 1 wetlands; and/or
(c) Wetlands of any size located at the headwaters of a watercourse,
i.e., a wetland with a perennial or seasonal outflow channel, but with no defined influent
channel, but are not Category 1 wetlands; and/or
(d) Wetlands having minimum existing evidence of human -related
physical alteration such as diking, ditching or channelization; and/or
Current rating: Using the 2014 WADOE Wetland Rating system (2023
updated form) and rating the wetland as a depressional type wetland,
this wetland scored a total of 16 points with 5 for habitat which indicates
a Category III wetland.
According to City of Renton Municipal Code 4-3-050G.2, Category III
wetlands with 5 habitat points and a land use such as a subdivision
have a 100’ buffer measured from the wetland edge. This wetland is at
its closet point just over 105’ from the site. Therefore the buffer of this
off-site wetland does not extend onto the site.
Proposed Project
The proposed project is a 6 lot plat with associated infrastructure. The
City requires Pasco Place SE, which abuts the south end of the site to be
extended into the site. This will require filling of Wetland A completely to
construct the road. Wetland B, a small low function Category IV wetland
which is 469sf in size is also proposed to be filled. This wetland is of very
low function, yet the wetland and its associated buffer greatly reduce the
available area for development on the site.
These two small, Category IV wetlands with a total area of 991sf area
proposed to be mitigated off-site within a City of Renton Mitigation bank.
Section 4.3.050H allows alterations to wetlands under the following
criteria;
Ultima/#25-103
Sewall Wetland Consulting, Inc.
May 20, 2025
Page 16
4. Criteria for Approving Wetland Alterations: Wetland alterations may only be authorized
after the City makes a written finding that the proposal is c onsistent with the following criteria:
a. No Net Loss: Activities that adversely affect wetlands and/or wetland buffers shall
include mitigation sufficient to achieve no net loss of wetland function and acreage and to
achieve, where practicable, a net resource gain in wetlands over present conditions. The
concept of “no net loss” means to create, restore and/or enhance a wetland so that there is
no reduction to total wetland acreage and/or function.
Response: The functions and are of the two small, isolated Category IV
wetlands areas proposed to be mitigated through use of the City
Mitigation bank or King County Mitigation Reserves program. The
mitigation will be off-site mitigation at City approved ratios of 1.5:1 for
creation.
b. Compensation for wetland alterations shall occur in the following order of preference:
i. Re-establishing wetlands on upland sites that were formerly wetlands.
Response: Creating wetlands on the site is not feasible with the required
road location to pass through Wetland A. If wetland A were mitigated on
site it would result in expanding Wetland B which would push the buffer
further onto the site making the project impracticable.
ii. Rehabilitating wetlands for the purposes of repairing or restoring natural and/or
historic functions.
Response: This is not feasible on this site.
iii. Creating wetlands on disturbed upland sites such as those consisting primarily of
nonnative, invasive plant species.
Response: This is not feasible on this site.
Ultima/#25-103
Sewall Wetland Consulting, Inc.
May 20, 2025
Page 17
iv. Enhancing significantly degraded wetlands.
Response: This is not feasible on this site
v. Preserving Category I or II wetlands that are under imminent threat; provided, that
preservation shall only be allowed in combination with other forms of mitigation and
when the Administrator determines that the overall mitigation package fully replaces
the functions and values lost due to development.
Response: This is not feasible on this site.
vi. Cooperative compensation to mitigation banks or in-lieu fee programs, as
indicated in subsection G9e of this Section.
Response: The proposed mitigation for the impacts to 991sf of Category
IV wetland is to participate in the City’s mitigation bank program or King
County Mitigation Reserves program to mitigate the functions and values
of these small, low function wetlands.
c. Mitigation Ratios for Wetland Impacts: Compensatory mitigation for wetland
alterations shall be based on the wetland category and the type of mitigation activity
proposed. The replacement ratio shall be determined according to the ratios provided in
the table below. The created, re -established, rehabilitated, or enhanced wetland area shall
at a minimum provide a level of functions equivalent to the wetland being altered and shall
be located in an appropriate landscape settin g.

HGM Classification of Wetlands in Western Washington
For questions 1-7, the criteria described must apply to the entire unit being rated.
If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably
have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply,
and go to Question 8.
Are the water levels in the entire unit usually controlled by tides except during floods?
YES-the wetland class is Tidal Fringe-go to 1.1
fthe salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)?
NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is
Saltwater Tidal Fringe, it is an Estuarine wetland and is not scored. This method cannot be used to score
functions for estuarine wetlands.
2. The entire wetland unit is flat, and precipitation is the only source (>90%) of water to it. Groundwater and
surface water runoff are NOT sources of water to the unit.
JO - go to 3\) YES - The wetland class is Flats
land can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size,
At least 30% of the open water area is deeper than 6.6 ft (2 m).
YES-The wetland class is Lake Fringe (Lacustrine Fringe)
Joesthe entire wetland unit meet all of the following criteria?
_The wetland is on a slope (slope can be very gradual),
_The water flows through the wetland in one direction (unidirectional) and usually comes from seeps.
It may flow subsurface, as sheet flow, or in a swale without distinct banks,
The water leaves the wetland without being impounded.
YES - The wetland class is Slope
•TSurface 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).

Does the entire wetland unit meet all of the following criteria?
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that
stream or river,
The overbank flooding occurs at least once every 2 years.
NO - go to 6^ YES - The wetland class is Riverine
le Riverine unit can contain depressions that are filled with water when the river is not flooding
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at
some time during the year? This means that any ojjtlelif-prosent. is higher tliaaJJie-interloTof'th^wetland.
NO - go to 7 ^— YES-The wetland class is pepressiQnaJL^---^
7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding?
The unit does not pond surface water more than a few inches. The unit seems to be maintained by high
groundwater in the area. The wetland may be ditched but has no obvious natural outlet.
NO-go to 8 YES-The wetland class is Oepressional
Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For
example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a
Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE
HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a
rough sketch to help you decide). Use the following table to identify the appropriate class to use for the
rating system if you have several HGM classes present within the wetland unit being scored.
NOTE: Use this table only if the class that is recommended in the second column represents 10% or more
of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than
10% of the unit; classify the wetland using the class that represents more than 90% of the total area.

WDFW Priority Habitats
See complete descriptions of Priority Habitats listed by WDFW, and the counties in which they can be
found, in: Washington Department of Fish and Wildlife. 2008 (current year, as revised). Priority Habitat and
Species List.133 This list was updated for consistency with guidance from WDFW.
This question is independent of the land use between the wetland unit and the Priority Habitat. All vegetated
wetlands are by definition a Priority Habitat but are not included in this list because they are addressed by this
rating system.
Count how many of the following Priority Habitats are within 330 ft (100 m) of the wetland unit:
— Aspen Stands: Pure or mixed stands of aspen greater than 1 ac (0.4 ha).
— Biodiversity Areas and Corridors: Areas of habitat that are relatively important to various species of
native fish and wildlife. This habitat automatically counts if mapped on the PHS online map within 100m
of the wetland. If not mapped, a determination can be made in the field.
— Caves: A naturally occurring cavity, recess, void, or system of interconnected passages under the earth
in soils, rock, ice, or other geological formations and is large enough to contain a human.
— Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation.
— Fresh Deepwater: Lands permanently flooded with freshwater, including environments where surface
water is permanent and often deep, so that water, rather than air, is the principal medium within which
the dominant organisms live. Substrate does not support emergent vegetation. Do not select if Instream
habitat is also present, or if the entire Deepwater feature is included in the wetland unit being rated
(such as a pond with a vegetated fringe).
— Herbaceous Balds: Variable size patches of grass and forbs on shallow soils over bedrock.
— 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. Do not select if
Fresh Deepwater habitat is also present.
— Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast
Nearshore, and Puget Sound Nearshore.
— 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) diameter at breast height (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.

are Priority Habitats
— Riparian: The area adjacent to freshwater aquatic systems with flowing or standing water that contains
elements of both aquatic and terrestrial ecosystems which mutually influence each other.
— 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

— 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.
— Westside Prairies: Herbaceous, non-forested plant communities that can either take the form of a dry
prairie or a wet prairie.

HGM Classification of Wetlands in Western Washington
For questions 1-7, the criteria described must apply to the entire unit being rated.
If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably
have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply,
and go to Question 8.
1. Are the water levels in the entire unit usually controlled by tides except during floods?
<^"j\IO - gotcT^ YES - the wetland class is Tidal Fringe - go to 1.1
1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)?
NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is
Saltwater Tidal Fringe, it is an Estuarine wetland and is not scored. This method cannot be used to score
functions for estuarine wetlands.
2. The entire wetland unit is flat, and precipitation is the only source (>90%) of water to it. Groundwater and
surface water runoff are NOT sources of water to the unit.
•^O^goto^lr* YES - The wetland class is Flats
^-Ji-/_trTwetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size,
At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO - go to4} YES - The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
The wetland is on a slope (slope can be very gradual),
The water flows through the wetland in one direction (unidirectional) and usually comes from seeps.
It may flow subsurface, as sheet flow, or in a swale without distinct banks,
The water leaves the wetland without being impounded.
JO - go to 53 YES - The wetland class is Slope
NOTETSurface 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).

Wetland name or number
Does the entire wetland unit meet all of the following criteria?
The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that
stream or river,
The overbank flooding occurs at least once every 2 years.
10 - go to§P YES - The wetland class is Riverine
rrfhe Riverine unit can contain depressions that are filled with water when the river is not flooding
Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at
some time during the year? This means that any outlet, if present, is higher than the interior of the wetland.
NO-go to 7 ^ YES-The wetland class is Depressional
7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding?
The unit does not pond surface water more than a few inches. The unit seems to be maintained by high
groundwater in the area. The wetland may be ditched but has no obvious natural outlet.
NO - go to 8 YES - The wetland class is Depressional
8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For
example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a
Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE
HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a
rough sketch to help you decide). Use the following table to identify the appropriate class to use for the
rating system if you have several HGM classes present within the wetland unit being scored.
NOTE: Use this table only if the class that is recommended in the second column represents 10% or more
of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than
10% of the unit; classify the wetland using the class that represents more than 90% of the total area.

WDFW Priority Habitats
See complete descriptions of Priority Habitats listed by WDFW, and the counties in which they can be
found, in: Washington Department of Fish and Wildlife. 2008 (current year, as revised). Priority Habitat and
Species List.133 This list was updated for consistency with guidance from WDFW.
This question is independent of the land use between the wetland unit and the Priority Habitat. All vegetated
wetlands are by definition a Priority Habitat but are not included in this list because they are addressed by this
rating system.
Count how many of the following Priority Habitats are within 330 ft (100 m) of the wetland unit:
— Aspen Stands: Pure or mixed stands of aspen greater than 1 ac (0.4 ha).
— Biodiversity Areas and Corridors: Areas of habitat that are relatively important to various species of
native fish and wildlife. This habitat automatically counts if mapped on the PHS online map within 100m
of the wetland. If not mapped, a determination can be made in the field.
— Caves: A naturally occurring cavity, recess, void, or system of interconnected passages under the earth
in soils, rock, ice, or other geological formations and is large enough to contain a human.
— Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation.
— Fresh Deepwater: Lands permanently flooded with freshwater, including environments where surface
water is permanent and often deep, so that water, rather than air, is the principal medium within which
the dominant organisms live. Substrate does not support emergent vegetation. Do not select if Instream
habitat is also present, or if the entire Deepwater feature is included in the wetland unit being rated
(such as a pond with a vegetated fringe).
— Herbaceous Balds: Variable size patches of grass and forbs on shallow soils over bedrock.
— 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. Do not select if
Fresh Deepwater habitat is also present.
— Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast
Nearshore, and Puget Sound Nearshore.
— 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) diameter at breast height (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.

the oak component is important. For single oaks or oak stands <0.4 ha in urban areas, WDFW's
Management Recommendations for Oregon White Oak134 provides more detail for determining if they
are Priority Habitats
— Riparian: The area adjacent to freshwater aquatic systems with flowing or standing water that contains
elements of both aquatic and terrestrial ecosystems which mutually influence each other.
— 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.
— Westside Prairies: Herbaceous, non-forested plant communities that can either take the form of a dry
prairie or a wet prairie.
