Introduction
Olympic Wetland Resources, LLC has been authorized by John Colden to perform a Wetland Delineation
and Analysis report on the subject parcel on Marrowstone Island, Washington. Field work was conducted
on March 2, 2020 to determine the wetland boundary and rating of a wetland as mapped on the Jefferson
County Critical Areas Map. The wetland boundaries are accurate within 5 feet as determined by
topography, soils, and vegetation.
Project Proposal
The project proposal includes installing a septic for a single family residence that will be designed by
Everett Sorenson. Currently there is an existing homesite that will be expanded to accommodate a larger
home. John Colden owns the parcel and this delineation and buffer determination will determine
development potential.
Site Description and Existing Conditions
The parcel slopes gently west towards Fort Flagler Road (SR 116). Jefferson County Critical Areas map
indicates a small wetland on the lower elevations near the road. This wetland is shown to extend south to
adjacent parcels. The majority of the parcel is forested with an understory of native shrubs and herbaceous
species.

Methodology
Due to the mapped wetlands on this parcel this Wetland Delineation and Analysis is required by Jefferson
County Environmental Health and DCD as part of the permit application process. This assessment is
prepared according to the current Unified Development Code, Chapter 18.22, Critical Areas (18.22.270,
18.22.330, 18.22.440 and 18.22.450) with updates from March 10, 2020.
The characteristics of an area that result in its classification as "wetland" have been formally defined by
federal and state agencies. All wetland delineations must be prepared in accordance with the U.S. Army
Corps of Engineers Regional Supplement to the Corps of Engineers Wetland Delineation Manual:

Background Information
The following resources were consulted prior to field work for this project: 1�91 '�C�,
• Jefferson County UDC Chapter 18 Critical Areas (updated March 2020)����''rpr
• Washington Department of Fish and Wildlife Priority Habitat Species (PHS)
Aerial Photographs (Google Internet)

Wetland Delineation Findings
This delineation follows a wet spring during the early start of the growing season. Vegetation was mostly
dormant with minimal leaf budding. Air and temperature were from 43' to 41' (soils at 16" below the
surface). Determining a wetland edge is difficult during early spring due to seasonal high water table and
dormant herbaceous species. It is advised to re-examine the site later in the spring when the water tables
are stable.
The Jefferson County Critical Areas map indicates only a small area in the western end the 1.6 acre parcel
is mapped as wetland. This area is along Flagler Road historically be due to the elevation and
construction of Fort Flagler Road interrupting and capturing the flow of stormwater towards Mystery Bay.
NRCS soil maps do not indicate hydric soils on site. (Figure 1).
The wetland edge was determined by examining soils, vegetation layers, and hydrology at each data point.
The wetland boundary is defined by a slight drop in topography, change of vegetation (predominantly
FAC), the presence of redoximorphic features in the soils, and the presence of hydrology both in the pit
and ponding nearby.
Findings reveal the wetland edge corresponds roughly with the Jefferson County Critical Areas wetland
map. Once the wetland edge was established it was flagged at 20' to 30' intervals. The Findings Map
(Figure 2) includes the property boundaries, delineated wetland edge, associated buffers, and data point
locations overlaid on an aerial photograph with 5'contours (Google).
Soils
NRCS Soil Survey (internet) lists all soils on the subject parcel as DaC Dabob very gravelly loam and
Casey silt Loam. Findings were relatively consistent with this soil description as observed in the 5 data
points and soil test pit locations.
The Soil matrix color in Data Points 1, 2, and 4 were very dark brown (1 OYR 2/2) with no redoximorphic
features. Below 6 to 9" soils were greyish brown and sandy (1 OYR 5/2) with abundant redoximorphic
features in a loamy clay layer (1 OYR 4/4). Water or soil saturation was only observed at the bottom inch or
less of the 16" soil test pits.
Data Point 3 was slightly upslope to the east and did not contain hydric soils. The soil matrix color was
black 1 OYR 2/1 overlaying a light brown soil 1 OY/R dry soil. Data Point 3 is clearly outside the wetland.

March 2020
Data Point 5 was 40 feet to the east of Flagler road and had wetland soils. There was a mature Douglas fir
with an understory of shrubs that clearly defined the wetland/upland boundary.
Vegetation
This wetland delineation was conducted during very early spring when most vegetation was in bud or
starting to show leaf budding. Trees and shrubs were identified by familiarity of branching, bud
formation, and residual leaves on the ground. There is a healthy understory of shubs with down branches
that provide habitat for many species. There were very few non-native species. Most species on the
parcel are rated as FAC and can also be found in uplands.
The dominant vegetation and percent cover are recorded on the Data Forms at the end of this

Hydrology
Hydrology was present at DP 1, 2, 4, and 5 and occurred 15 inches below the surface. Surface ponding
and soil saturation were observed near Flagler Road. Due to a recent series of storms with'signiflcant
rainfall the water table was potentially higher than normal and the drainage ditch along Flagler Road had
flowing water. All water from this site will eventually end up in Mystery Bay less than 1 iiie. from the
parcel.

Watershed and tlydrologic Assessment
This parcel drains toward Mystery Bay, Nordland Washington. The subject parcel rises slightly upslope
to an elevation of 30 to 40 feet above Flagler Road which is near sea level. Marrowstone is relatively flat
with no significant elevation and harbors several wetland areas due to glacial compacted soils.
Potential Impacts of Proposed Development
Short-term impacts during the septic installation and completion of the house will be minimized by
careful construction practices. Quantities of excavated soils for the septic system and the final design for
the single-family residence will be discussed in detail in the final plans. All other impacts and impervious
surfaces will be addressed when the final plans are submitted. All construction will take place outside of
delineated buffers and are over 150 feet from the waters of Mystery Bay. There will be "No Net Loss" of
any ecological functions during or after construction.
The proposed building envelope consists of an existing cabin and no trees will be removed for the new
homesite. Due to the gently sloping landscape there will be no potential for erosion or siltation entering
Mystery Bay or the delineated wetland. Best Management Practices (BMPs) should be followed during
and after construction. There will be no alteration of surface water flows since the site is moderately
sloped, well drained and final contours will follow the original slopes in the landscape.

The final authority over approval of this Wetland Delineation and Categorization Buffer will be Jefferson
County DCD and Department of Environmental Public Health. Final jurisdictional authority over
wetland, shoreline, and buffer determinations rests with the local, state and federal agencies. If there are
further questions or planning requirements for this project, please do not hesitate to call.
Summary
Olympic Wetland Resources, LLC conducted a Wetland Delineation and Analysis for John Colden on his
parcel located near Nordland Washington on March 2, 2020.
The proposed project includes the installation of a septic system and permitting of a single-family
residence.
Findings from this report include a Category III wetland with 60-foot buffers. The final site plan will
indicate the building envelope and septic location outside all wetland buffers. Best Management Practices
(BMPs) should be followed during and after construction to insure "No Net Loss" of ecological functions
or impacts to wetlands or waters of Mystery Bay.

Applied Methodology for Wetland Delineation _ Ew;�r�rvn:�rl..
2020
The characteristics of an area that result in its classification as "wetland" have been formally defined by
federal and state agencies. All wetland delineations must be prepared in accordance with the U.S. Army
Corps of Engineers Regional Supplement to the Corps of Engineers Wetland Delineation Manual:
Western Mountains, Valleys, and Coast Region, Version 2.0 (May 2010).
The wetland delineation report will include how the wetland boundary was determined and include a map
of the delineated wetland, data sheets, and descriptions of site characteristics in both upland and wetland.
The methodology outlined in the Corps Manual is based upon three essential characteristics of wetlands:
(1) hydrophytic vegetation; (2) hydric soils; and (3) wetland hydrology. Field indicators of these three
characteristics must all be present to determine that an area is a wetland (unless problem areas or atypical
situations are encountered). All wetlands identified using this methodology may be regulated regardless of
size.
Determining Wetland Edges
Wetland edges were determined by establishing pairs of data points. In general, the wetland edge falls
between the sampling plot with all three positive wetland requirements and where one or all of the
requirements were not present. Other difficult situations encountered in identifying wetlands are described in
greater detail in the Corps Regional Supplement.
Hydrophytic Vegetation
Hydrophytic vegetation decisions are based on communities of species that tolerate prolonged inundation
or soil saturation during the growing season. Vegetation sampling will follow the guidance outlined in
the Corps Manual. Several methods can be applied; however, one method includes recording vegetation
of a sampling point to determine if more than 50% of the dominant species have a wetland indicator status
of OBL, FACW, or FAC. Dominance of plant species is determined by calculating actual aerial cover
within an appropriate radius for trees, shrubs, and herbaceous species at each data point. Commonly
occurring plant species have been rated by the U.S. Army Corps of En insets Nations! Wetland Plant List
(NWPL). 2014 COE Western Mountains, Valleys, and Coast. During the fieldwork, each species was
recorded and given a rating based on indicator status and percent cover. The 2014 NWPL will be used in
any wetland delineations or determinations performed after May 1, 2014.
Key to Wetland Indicator Status codes — Northwest Region (Source: USFWS, 1988, 1993):
OBL Obligate: species that almost always occur in wetlands under natural conditions (est. probability
>99%).
FACW Facultative wetland: species that usually occur in wetlands (est. probability 67 to 99%), but are
occasionally found in non -wetlands.
FAC Facultative: species that are equally likely to occur in wetlands or non -wetlands (est. probability 34
to 66%).
FACU Facultative upland: species that usually occur in non -wetlands (est. probability 67 to 99%), but are
occasionally found in wetlands.
UPL Upland: species that almost always occur in non -wetlands under normal conditions (est. probability
>99%).
NL Not listed: species that are not listed by USFWS (1988, 1993) and are presumed to be upland
species.
NI No indicator: species for which insufficient information is available to determine status, or which
were not evaluated by USFWS.
Hydrophytic Soil
A hydric soil is a soil that forms under conditions of saturation, flooding, or pondind"ll"sting long enough '
during the growing season to result in an anaerobic upper layer (USDA-NRCS 1995). Hydric soils favor ri
the growth and regeneration of hydrophytic vegetation. The Natural Resources Conservation Service
(NRCS), in cooperation with the National Technical Committee for Hydric Soils, has compiled lists of
hydric soils. It is common, however, for a map unit of non -wetland (non-hydric) soil to have inclusions
of hydric soil, and vice versa. Therefore, field examination of soil conditions is important to determine if
hydric soil conditions exist.
In general, anaerobic conditions create certain characteristics in hydric soils, collectively known as
"redoximorphic features" and include low chroma, depletions, gleying, sulfidic material (rotten egg odor)
and/or high organic content within the soil immediately below the A -horizon. Holes were dug on the site and
soil colors were described by texture, color name, value, and chroma (Munsell Color 2000). Soils were
categorized in accordance with NRCS Field Indicators of Hydric Soils of the United States (Version 7.0,
2010 with updates). This manual further defines organic soils, sandy soils, loamy and clayey soils with a
numeric value.
Wetland Hydrology
Water must be present in order for wetlands to exist; however, it need not be present throughout the entire
year. The standard requires 14 or more consecutive days of flooding, or ponding or a water table 12" or
less below the soil surface during the growing season. The growing season has begun when two or more
different non -evergreen vascular plants are identified.
Indicators of hydrology may include, but are not necessarily limited to, ponded water, drainage patterns, drift
lines, sediment deposition, historic records, water -stained leaves, cracking of the soil surface, oxidized root
channels, and/or sediment deposits. The Regional Supplements provide methods for evaluating situations
in wetlands that periodically lack indicators of wetland hydrology but where hydric soils and hydrophytic
vegetation are present.
Categorization
Wetland categorization is determined using the Washington State Department of Ecology (DOE) Wetland
Rating System Revised (Ecology Publication #14-06-029, Effective January 2015 and as amended),
according to type and category of wetland. The wetland is assigned a score of High, Medium, or Low for
wetland values; including water quality function, hydrologic function, and habitat function. The total rating
determines the category of wetland. Wetlands are rated as entire systems and quite often exceed project
boundaries. Ratings range from Category I to Category IV. Buffers are assigned according to intensity of
land use for specific parcel size using final numeric scores. Category I indicates wetlands with the highest
quality of function for improving water quality, preventing flooding problems, and providing habitat. These
are not replaceable and therefore receive the largest buffer and highest protection.
Classification
Two classification systems are commonly used to describe wetlands. The hydrogeomorphic (HGM)
system describes wetlands in terms of their position in the landscape and the movement of water in the
wetland (Brinson, 1993). The U.S. Fish and Wildlife Service classification system (Cowardin et al.,
1979) describes wetlands in terms of their vegetation communities; for example, emergent (PEM), scrub-
(PSS) shrub, and forested (PFO) community types.

HABITAT FUNCTIONS - Indicators that site functions to provide important habitat
H 1.0. Does the site have the potential to provide habitat?
H 1.1. Structure of plant community: Indicators are Cowardin classes and strata within the Forested class. Check the
Cowardin plant classes in the wetland. Up to 10 patches may be combined for each class to meet the threshold
of % ac or more than 10% of the unit if it is smaller than 2.5 oc. Add the number of structures checked.
_Aquatic bed 4 structures or more: points = 4
Emergent 3 structures: points = 2
_Scrub -shrub (areas where shrubs have > 30% cover) 2 structures: points = 1
_Forested (areas where trees have > 30% cover) 1 structure: points = 0
If the unit has a Forested class, check if.•
YThe Forested class has 3 out of 5 strata (canopy, sub -canopy, shrubs, herbaceous, moss/ground-cover)
that each cover 20% within the Forested polygon
H 1.2. Hydroperiods
Check the types of water regimes (hydroperiods) present within the wetland. The water regime has to cover
more than 10% of the wetland or Y4 ac to count (see text for descriptions of hydroperiods).
_Permanently flooded or inundated 4 or more types present: points = 3
Seasonally flooded or inundated 3 types present: points = 2
_Occasionally flooded or inundated 2 types present: points = 1
__Saturated only 1 type present: points = 0
_
_Permanently flowing stream or river in, or adjacent to, the wetland
_Seasonally flowing stream in, or adjacent to, the wetland
_Lake Fringe wetland 2 points
Freshwater tidal wetland 2 points
H 1.3. Richness of plant species
Count the number of plant species in the wetland that cover at least 10 ftZ.
Different patches of the same species can be combined to meet the size threshold and you do not have to name
the species. Do not include Eurasian milfoil, reed canarygrass, purple loosestrife, Canadian thistle
If you counted: > 19 species points = 2
5 - 19 species points = 1
< 5 species points = 0
H 1.4. Interspersion of habitats
Decide from the diagrams below whether interspersion among Cowardin plants classes (described in H 1.1), or
the classes and unvegetated areas (can include open water or mudflats) is high, moderate, low, or none. If you
have four or more plant classes or three classes and open water, the rating is always high.
