INTRODUCTION
The Wetland Corps has been authorized by the Drew Davies to perform a wetland
delineation at the above referenced property located in Allyn, Mason County,
Washington, (Tax Identification Number 122205015003). The delineation was
performed to identify wetlands and associated buffers within the parcel. The delineation
was completed on May 28', 2008.
The subject property is located in the NE'/4 4 Section 20, Township 22 North, Range 01
West WM(Figure 1 Vicinity Map). The parcel is approximately 1.8 acres in size.
For the purposes of federal, Washington State, and Mason County jurisdictional
oversight, methodology used for the wetland delineation is consistent with the wetland
definition provided in paragraph 25a of the Washington State Wetlands Identification and
Delineation Manual (Washington State Department of Ecology, 1997). The sections
below provide: (1) an introduction to the site; (2) a description of methods used in the
field delineation; and, (3)technical results.
GENERAL SITE CONDITIONS
The subject parcel is accessed via an easement off of North Bay Road, which enters the
parcel at the southeast portion of the property. North Bay Road makes up the western
property boundary. The shoreline of Case Inlet borders the eastern portion of the parcel,
and residential parcels of similar size and shape border the parcel to the north and south.
Currently the parcel contains a small cabin near the shoreline, occupying approximately
900 square feet.
The majority of the parcel is maintained as residential lawn, with the exception of the
easternmost portion of the parcel which contains a forested/shrub wetland. The area
maintained as residential lawn extends approximately 8,000 square feet into the
delineated wetland boundary. Three curtain drains are situated within the wetland, which
converge into a single culvert that directs water out of the wetland, extends
approximately 275 feet under the lawn area and drains into the shoreline of Case Inlet.
Since the wetland hydrology has been altered and portions of the vegetation within the

wetland have been replaced by lawn, this study site meets criteria for an Atypical
Situation.
METHODOLOGY
Review of Existing Information
Consistent with procedures detailed in the Washington State Wetlands Identification and
Delineation Manual (Washington State Department of Ecologic, 1997). (1997 .Manual),
preliminary information was gathered on the project site prior to the field review and
delineation. General information sources included: United States Geological Service
(USGS) topographic maps, 1974 United States Fish and Wildlife Service (USFWS)
National Wetland Inventory (NWI) maps, the Soil Survey of Mason County Area,
Washington (USDA, 1951), 2005 Mason County Online GIS Aerial Photo, and Mason
County's critical areas regulations.
Field Delineation
Methodology used for wetland delineation was consistent with the technical approaches
articulated in the 1997 Manual. This document is the wetland delineation manual that is
used in determining wetland areas when applying state and local government regulations
under the Shoreline Management Act and the Growth Management Act in Washington
State.
The extent and location of suspect wetlands were determined during field work
performed on May 2e, 2008. Field work was conducted under cloudy skies with an
ambient temperature ranging between 60 and 70 degrees Fahrenheit. The time of year
and recent precipitation history were considered in assessing the extent of the suspect
wetland presumed to exist on site.
Specific field methodology used in determining the extent and location of wetland areas
include:
1. As part of the initial project site reconnaissance, the site was walked to determine
the general extent and location of potential wetland areas;
2. Wetland and upland sample plots were established in the identified potential
wetland areas and in the adjacent upland area; and
3. Wetland boundaries were delineated with flagging by noting localized topography
and vegetation patterns and comparing parameters of hydrology, soil, and
vegetation with data collected at the wetland and upland sample plots.
The project area was investigated and data was collected at three sample plot locations,
within the wetland and corresponding upland. One data ,plot was recorded within the
relatively undisturbed portion of the wetland within the southeastern portion of the
property, and two data plots were recorded within the northern half of the wetland within

the property. Data collected at each sample plot were entered onto a Routine Wetland
Determination Data Form (Washington State Department of Ecology 1997). Copies of
data forms for each sample plot are provided in Appendix A.
BACKGROUND INF40RMATION
Mason County Soil Survey
The soil survey of Mason County indicates one onsite soil type within the approximate
parcel location,(USDA, 1951):
McKenna gravelly loam, 0 to 3 percent slopes (Mc) The McKenna series consists of
poorly drained, very dark, gravelly soils in depressions and along natural drainageways.
They have developed in Vashon glacial drift, under rainfall that ranges from 45 to 60
inches a year. The vegetation consists of deciduous trees and shrubs, sedges, reeds,
spirea, and wild rose, with occasional thickets of quaking aspen and Oregon-oak.
McKenna soils occur mainly in association with the Alderwood and Everett soils and
only rarely with the Grove or Shelton soils. McKenna soils differ from the Norma and
Bellingham soils in having very gravelly subsoils and substrata. They are much darker
colored than the Koch soils. The Deckerville soils, which closely resemble the McKenna,
have developed from more basic parent material. McKenna gravelly loam, 0 to 3
percent slopes (Mc).This soil occurs as small scattered areas.
A more detailed soil description can be found in Appendix B Mason Soil Survey Text.
The Masan:Soi1:Survcy snap is.shown in Figure 4.
National Wetlands Inventory
The USFWS NWI map (online wetlands mapper) shows one estuarine wetland mapped
within the eastern portion of the approximate parcel location, and is associated with Case
Inlet. The classified by the NWI as [E] Estuarine, [2] Intertidal, [AB] Aquatic Bed/[US]
Unconsolidated Shore, [N] Regularly Flooded (Figure 3. National Wetland Inventory
Map).
Department of Natural Resources Water Resource
The Department of Natural Resources Water Resource Map shows no streams within the
approximate parcel vicinity. The nearest stream is mapped approximately 1000 feet north of the
subject parcel(Figure 6. DNR Stream Map).
WETLAND DELINEATION RESULTS
One slope freshwater wetland was identified within the western side of the subject
property. The wetland is classified as a slope wetland because water generally moves in
one direction (easterly) and water leaves the wetland without being impounded. Surface
water leaves the wetland via curtain drains and also through an untyped channel located
on the parcel to the south of the property.

A portion of the wetland meets DOE criteria for an atypical situation due to the alteration
of hydrology, by the placement of three curtain drains that direct water to Case Inlet; and
also due to the alteration of vegetation by removal of native vegetation and maintenance
of lawn grass. Based on inundation/soil saturation during the growing season throughout
the undisturbed portions of the wetland, it appears that wetland hydrology is most
significantly altered in the areas near the curtain drains, within the lawn area. It should be
.noted that the entire wetland hydrology has been altered by the-curtain drains. However,
based on observed surface inundation during the growing season within areas dominated
by facultative and obligate wetland vegetation, surface water does not appear to be
greatly reduced within undisturbed portions of the wetland, likely due to the very poor
drainage of the onsite soil.

In Order to identify the extent of Wetland hydrology for-delineation purposes within the
lawn area, adjacent undisturbed areas in the same topographic position that are similarly
influenced by the same sources of inundation were used develop a pattern of wetland
hydrology prior to disturbance.
The Mason County GIS 2005 aerial photo indicates that the site was previously occupied
by a mixed forested/shrub community similar to what is present to the south of the grass
area and in non-cleared areas to the-north. This being the case, the identification of the
extent and type of wetland vegetation that previously existed was obtained by examining
the vegetation in adjacent areas located in non-disturbed areas of the same topographic

position. In addition, wetland vegetation that is beginning to voluntarily recruit the
disturbed area, such as creeping buttercup (Ranunculus repens, FACW), big leaf sedge
(Carex amplifolia, FACW), and skunk cabbage (Lysichiton americanum, OBL) were
used to characterize the original ve vegetation and identify
g the extent of the wetland
boundary. The portion of the wetland that is disturbed by the vegetation removal
occupies approximately 8,000 square feet.

Vegetation
The vegetatively undisturbed portions of the wetland within the property contains an
overstory of red alder (Alnus rubra, FAC) and western red cedar (Thuja plicata, FAC)
with a shrub understory of salmonberry (Rubus spectabilis, FAC+) and nootka rose (Rosa
nutkana, FAC), a and herbaceous layer comprised of lady fern (Athyrium frlix femina,
FAC), water horsetail (Equisitum fluviatile, OBL), wild lily-of-the-valley (Maianthemum
dilatatum, FAC), piggy back plant (Tolmiea menziesii, FAC), reed canarygrass (Phalaris
arundinacea, FACW), creeping buttercup (Ranunculus repens, FACW) and slough sedge
(Carex obnupta, OBL). The volunteer vegetation within the disturbed portion of the
wetland, is comprised of creeping buttercup (Ranunculus repens, FACW), big leaf sedge
(Carex amplifolia, FACW), skunk cabbage (Lysichiton americanum, OBL) and piggy
back plant (Tolmiea menziesii, FAC), and lesser amounts of salmonberry (Rubus
spectabilis, FAC). A portion of the disturbed area contains a nonnative pine species of
similar size and age, which appears to have been planted and was not included in the
plant species inventory.

disturbed data plot revealed similar characteristics, with the exception of a 4-inch upper
layer of gravelly sandy loam of matrix chroma 1 OYR 4/4. This upper layer appears to be
nonnative. The gravelly loam found in the wetland soils profiles is consistent with the
mapped soil type,McKenna gravelly loam. McKenna gravelly loam is listed on the 2008
National Hydric Soils List.
Hydrology
Although hydrology throughout the entire wetland has been altered due to the installation
of curtain drains, inundation and soil saturation were still present during the growing
season throughout the majority of the wetland. Hydrology was indicated within the
vegetatively undisturbed wetland data plots by FAC-neutral vegetation, drainage patterns,
sediment deposits, and water-stained leaves. In addition, portions of the wetland were
inundated up to four inches during the growing season. The physical extent of wetland
hydrology, prior to disturbance within the portion of the wetland that has been both
vegetatively and hydrologically disturbed was identified by developing a pattern using
adjacent undisturbed areas in the same topographic position that are similarly influenced
by the same sources of inundation.
Upland test pits showed no indicators of wetland hydrology.
WETLAND EVALUATION
The wetland within the western portion of the property meets criteria for a Slope wetland
per Washington State Wetland Rating System for Western Washington (Hruby 2004) for
the purposes of rating. Based on functional attributes associated with the wetland
including habitat, water quality, and hydrology functions, it has been rated as a Category
III wetland, scoring 41 points on the state rating form. The score for water quality
functions in this wetland is 14, hydrological functions scored 5, and the score for habitat
functions is 22 (see Appendix C for rating form). According to Table 17.01.070 D of the
Mason County Resource Ordinance, the base buffer width for a Category III Wetlands
scoring between 20 and 28 points in habitat function, within parcels intended for E
I
Moderate Impact Land Use require a base buffer width of 110 feet with an additional 15- e�cJ
foot building setback. Moderate Impact Land Use is described in Table 17.07.070 B of
the Mason County Resource Ordinance as single-family residential lots or residential
subdivisions with 1 unit/acre or less.
CONCLUSION
This wetland report documents the presence of one Category III Slope Wetland within
the western portion of the property. According to Table 17.01.070D of the Mason
County Resource Ordinance, both wetlands require a I I0-foot buffer with an additional
15-foot building setback for Moderate Impact Land Use (single-family residential lots
with less than one unit per acre).

Onsite Soil Conditions Used on Mason County Soil Survey
Subject Site Soils:
McKenna gravelly loam, 0 to 3 percent slopes(Mc)The McKenna series consists of poorly drained,very
dark, gravelly soils in depressions and along natural drainageways. They have developed in Vashon
glacial drift, under rainfall that ranges from 45 to 60 inches a year. The vegetation consists of deciduous
trees and shrubs, sedges, reeds, spirea, and wild rose, with occasional thickets of quaking aspen and
Oregon-oak. McKenna soils occur mainly in association with the Alderwood and Everett soils and only
rarely with the Grove or Shelton soils. McKenna soils differ from the Norma and Bellingham soils in
having very gravelly subsoils and substrata. They are much darker colored than the Koch soils. The
Deckerville soils, which closely resemble the McKenna, have developed from more basic parent
material. McKenna gravelly loam, 0 to 3 percent slopes(Mc).This soil occurs as small scattered areas.
A more detailed soil description can be found in Appendix B Mason Soil Survey Text.

APPENDIX B
Soil Survey Text
McKENNA SERIES
The McKenna series consists of poorly drained, very dark, gravelly soils in depressions
and along natural drainageways. They have developed in Vashon glacial drift, under
rainfall that ranges from 45 to 60 inches a year. The vegetation consists of deciduous
trees and shrubs, sedges, reeds, spirea, and wild rose, with occasional thickets of quaking
aspen and Oregon-oak. McKenna soils occur mainly in association with the Alderwood
and Everett soils and only rarely with the Grove or Shelton soils. McKenna soils differ
from the Norma and Bellingham soils in having very gravelly subsoils and substrata.
They are much darker colored than the Koch soils. The Deckerville soils, which closely
resemble the McKenna, have developed from more basic parent material. McKenna
gravelly loam, 0 to 3 percent slopes (Mc).This soil occurs as small scattered areas. The
surface soil is friable and granular, dark-gray (nearly black when moist) gravelly loam
that is high in organic matter. Below this, to depths of 10 to 15 inches, is fun, dark
grayish-brown very gravelly loam or gravelly clay loam that has a weak, subangular
blocky structure and is moderately high in organic matter. This grades to firm, massive
subsoil consisting of light brownish-gray very gravelly loamy sand. The substratum
begins at depths of 24 to 30 inches and consists of slightly to moderately compact, olive-
brown and palebrown coarse gravel and sand that is faintly mottled and stained.ln many
areas there is a thin, highly organic silty layer on the surface. The soil is medium acid to
strongly acid in all layers. Gravel prevents cultivation. The soil is wet most of the year
but dries rapidly in summer. Use and suitability.-Nearly all this soil is in natural cover. A
few areas have been cleared for pasture and grazing. The narrow areas of this soil, and of
other McKenna soils,provide green pastures after those on surrounding upland soils have
dried. This soil is in capability subclass IVw; it is poor for evergreen and deciduous trees.

wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To
maintain consistency between editions, the term"Estuarine"wetland is kept. Please note, however,that the
characteristics that define Category I and II estuarine wetlands have changed(see p. ).
2. Is the topography within the wetland flat and precipitation is only source(>90%) of water'to it.
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 wetland meet both of the following criteria?
The vegetated part of the wetland is on the shores of a body of open water(without any vegetation on the
surface)where at least 20 acres(8ha)are permanently inundated(ponded or flooded);
At least 30%of the open water area is deeper than 6.6(2 m)?
NO—go to 4 YES—The wetland class is Lake-fringe(Lacustrine Fringe)
4. Does the wetland meet all of the following criteria?
x The wetland is on a slope(slope can be very gradual).
x The water flows through the wetland in one direction(unidirectional) and usually comes from seeps. It may
flow subsurface, as sheetflow, or in a swale without distinct banks.
x The water leaves the wetland without being impounded?
NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and
shallow depressions or behind hummocks(depressions are usually<3 ft diameter and less than 1 foot deep).
NO—go to 5 YES—The wetland class is Slope
5. Is the wetland in a valley, or stream channel,where it gets inundated by overbank flooding from that stream or river? The
flooding should occur at least once every two years, on the average, to answer"yes". The wetland can contain
depressions that are filled with water when the river is not flooding.
NO—go to 6 YES—The wetland class is Riverine
6. Is the wetland in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year.
This means that any outlet, if present is higher than the interior of the wetland.
NO—go to 7 YES—The wetland class is Depressional
7. Is the wetland located in a very flat area with no obvious depressional and no stream or river running through it and
providing water. The wetland 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 seems to be difficult to classify. 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. Sometimes we find
characteristics of several different hydrogeomorphic classes within one wetland boundary. Use the following table to
identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland.
NOTE: Use this table only if the class that is recommended in the second column represents 10%or more of the total area
of the wetland being rated. If the area of the second class is less than 10% classify the wetland using the first class.

and/or forbs form the natural climax plant community.
Talus: Homogenous areas of rock rubble ranging in average size 0.15—2.Om(0.5—6.5 ft),
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.
Oregon white Oak: Woodlands stands of pure oak or oak/conifer associations where canopy 1
coverage of the oak component of the stand is 25%.
Urban Natural Open Space: A priority species resides within or is adjacent to the open space and
uses it for breeding and/or regular feeding;and/or the open space functions as a corridor connecting
other priority habitats,especially those that would otherwise be isolated; and/or the open space is an
isolated remnant of natural habitat larger than 4 ha(10 acres)and is surrounded by urban
development.

X Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches,and
may also include the backshore and adjacent components of the terrestrial landscape(e.g.,cliffs,
snags,mature trees,dunes,meadows)that are important to shoreline associated fish and wildlife and
that contribute to shoreline function(e.g.,sand/rock/log recruitment,nutrient contribution,erosion

C3 Bogs(seep. 88)
Does the wetland(or part of the wetland)meet both the criteria for soils and vegetation in bogs? Use
the key below to identify if the wetland is a bog. If you answer yes you will still need to rate the
wetland based on its function.
1. Does the wetland have organic soil horizons (i.e. layers of organic soil), either peats or mucks,that
compose 16 inches or more of the first 32 inches of soil profile? (See Appendix B for a field key to
identify organic soils)? YES=go to question 3 NO=go to question 2
2. Does the wetland have organic soils, either peats or mucks that are less than 16 inches deep over
bedrock, or an impermeable hardpan such as clay or volcanic ash,or that are floating on a lake or
pond? YES=go to question 3 NO=is not a bog for purpose of rating
3. Does the wetland have more than 70%cover of mosses at ground level, AND other plants, if
present,consist of the"bog"species listed in Table 3 as a significant component of the vegetation
(more than 30%of the total shrub and herbaceous cover consists of species in Table 3)?
YES=Is a bog for purpose of rating NO=go to question 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 hold dug at least 16"deep. If the pH is
less than 5.0 and the"bog"plant species in Table 3 are present,the wetland is a bog.
4. Is the wetland forested(>30%cover)with sitka spruce,subalpine fir,western red cedar,western
hemlock, lodgepole pine, quaking aspen,Englemann's spruce,or western white pine. WITH any of

C4 Forested Wetlands (seep. 96)
Does the wetland have at least 1 acre of forest that meet one of these criteria for the 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 function.
— Old-growth forests: (west of Cascade Crest) Stands of at least two three species forming a
multi-layered canopy with occasional small openings; with at least 8 trees/acre(20 trees/hectare)
that are at least 200 years of age OR have a diameter at breast height(dbh)of 32 inches(81 cm or
more).
NOTE: The criterion for dbh is based on measurements for upland forests. Two-hundred year old trees
in wetlands will often have a smaller dbh because their growth rates are often slower. The DFW
criterion is and"OR"so old-growth forests do not necessarily have to have trees of this diameter.
Mature forests: (west of the Cascade Crest) Stands where the largest trees are 80—200 years old
OR have an average diameters(dbh)exceeding 21 inches(53 cm); crown cover may be less than
100%; decay, decadence,numbers of snags,and quantity of large downed material is generally

Shoreline Wetland Identified as E2AB/USN
[E] Estuarine - The Estuarine System describes deepwater tidal habitats and adjacent tidal
wetlands with low energy and variable salinity, influenced and often semi-enclosed by land.
(2) Intertidal - This is defined as the area from extreme low water to extreme high water and
associated splash zone.
[AB] Aquatic Bed - Includes wetlands and deepwater habitats dominated by plants that
grow principally on or below the surface of the water for most of the growing season
in most years. Aquatic beds generally occur in water less than 2 meters (6.6 feet)
deep and are placed in the Littoral Subsystem (if in Lacustrine System )
[US) Unconsolidated Shore - Includes all wetland habitats having three
characteristics: (1) unconsolidated substrates with less than 75% areal cover of stones,
boulders, or bedrock; (2) less than 30% areal cover of vegetation other than pioneering
plants; and 3) any of the following water regimes: irregularly exposed, regularly
flooded,irregularly flooded, seasonally flooded, temporarily flooded, intermittently flooded,
saturated, seasonal-tidal, temporary-tidal,or artificially flooded. Intermittent or
intertidal channels of the Riverine System or intertidal channels of the Estuarine System are
classified as Streambed. Landforms such as beaches, bars, and flats are included in the
Unconsolidated Shore class.
[N] Regularly Flooded - Tidal water alternately floods and exposes land surface at
least once dail
