Delineation Report ii June 15,2020
INTRODUCTION
Ecological Land Services, Inc. (ELS) was contracted by R1 Peabody to complete a wetland
delineation and report for the lot at 71 NE Schooner, Mason County Parcel Numbers 122301-2-
038-2006, 122301-2-046-2008, and 123305200019, in Belfair, Washington. The lot is within a
portion of Section 30, Township 23 North, Range 1 West of the Willamette Meridian, in Mason
County, Washington (Figure 1). This report summarizes the findings of the wetland delineation
and categorization according to the Mason County Code (MCC), Chapter 8.52.110 Wetlands and
Chapter 8.52.170 Fish and Wildlife Habitat Conservation Areas for wetland categorization, stream
typing and required buffer widths.
METHODOLOGY
The onsite wetland determination followed the Routine Determination Method according to the
U.S. Army Corps of Engineers, Wetland Delineation Manual(Environmental Laboratory 1987) and
the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western
Mountains, Valleys and Coast Region, Version 2.0 (U.S. Army Engineer Research and
Development Center, 2010).
The Routine Determination Method examines three parameters—vegetation, soils, and
hydrology—to determine if wetlands exist in a given area. Hydrology is critical in determining
what is wetland, but is often difficult to assess because hydrologic conditions can change
periodically (hourly, daily, or seasonally). Consequently, it is necessary to determine if
hydrophytic vegetation and hydric soils are present, which would indicate that water is present
for long enough duration to support a wetland plant community. By definition, wetlands are
those areas that are inundated or saturated by surface or ground water at a frequency and
duration sufficient to support, and that under normal circumstances do support, a prevalence of
vegetation typically adapted for life in saturated soil conditions. Wetlands are regulated as
"Waters of the United States" by the U.S. Army Corps of Engineers (USACE), as "Waters of the
State" by the Washington Department of Ecology(Ecology), and locally by Mason County.
To determine the wetland boundary onsite, ELS collected data on vegetation, soils, and
hydrology. During the site visit on June 1, 2020, one wetland was identified at the east end of the
lot. The wetland continues offsite to the north, east, and south. Vegetation, hydrology, and soil
data were collected at two test plots to verify the boundary (Appendix A). ELS biologists hung
consecutively numbered florescent flagging labeled "Wetland Delineation". ELS determined the
boundaries through breaks in topography, changes in vegetation, and changes in water regime.
ELS located test plots and boundary flags using GPS to show their location on the site map (Figure
2).
SITE DESCRIPTION
The 0.24-acre lot is situated at the terminus of NE Schooner Place in Belfair, Mason County,
Washington (Figure 1). The wedge-shaped lot is narrow at NE Schooner Place and widens away
from the road (Figure 2). There is a relatively level terrace immediately adjacent to NE Schooner
RJ Peabody—Schooner Place Ecological Land Services,Inc.
Delineation Report 1 June 16,2020
Place and then the lot slopes down moderately to the wetland boundary at the east end
(Photoplates 1 and 2). The lot is undeveloped except for several perk holes which were dug on
the terrace. Vegetation onsite is characterized by a mix of deciduous and coniferous tree cover,
relatively sparse shrubs, and an even layer of ferns. ELS identified one wetland (Wetland A) was
identified and delineated along the east edge of the lot (Figure 2). Wetland A is a sloping system
that begins offsite to the north and continues offsite to the south.
VEGETATION
Vegetation in Wetland A was sampled at the west edge due to saturated soils. Therefore, the
overhanging tree vegetation was not representative of the wetland and shrub vegetation. Tree
cover outside the sampled area was dominated by red alder (Alnus rubra, FAC). The shrub layer
outside the sampled area was dominated by salmonberry (Rubus spectabilis, FAC). The
herbaceous layer was dominated by lady fern (Athyrium cyclosorum, FAC).
Upland vegetation was dominated by bigleaf maple (Acer macrophyllum, FACU) and Western
hemlock (Tsuga heterophylla, FACU) in the tree layer. The shrub layer was dominated by Oregon
grape (Mahonia nervosa, FACU). The herbaceous layer is dominated by sword fern (Polystichum
munitum, FACU), nipplewort (Lapsana communis, FACU), and herb Robert (Geranium
robertionum, FACU).
The dominant vegetation found onsite is recorded on the attached wetland determination data
forms (Appendix A). The indicator status, following the common and scientific names, indicates
how likely a species is to be found in wetlands. Listed from most likely to least likely to be found
in wetlands,the indicator status categories are:
■ OBL(obligate wetland)—Almost always occur in wetlands.
■ FACW (facultative wetland)— Usually occur in wetlands, but may occur in non-wetlands.
■ FAC(facultative)—Occur in wetlands and non-wetlands.
■ FACU (facultative upland)—Usually occur in non-wetlands, but may occur in wetlands.
■ UPL(obligate upland)—Almost never occur in wetlands.
■ NI (no indicator)—Status not yet determined.
SOILS
As referenced on the Natural Resources Conservation Service (NRCS 2020) website, the soil
mapped on the lot is Everett gravelly loamy sand, 5 to 15 percent slopes (Figure 4). Everett soils
are not classified as hydric (NRCS 2015). Areas mapped as hydric soils do not necessarily mean
that an area is or is not a wetland—hydrology, hydrophytic vegetation, and hydric soils must all
be present to classify an area as a wetland.
Soil data in Wetland A revealed a dark brown (10YR 2/1) mixed organic soil. Redoximorphic
features were absent. The area met hydric soil indicator Al, Histosal. The upland soils evaluated
onsite were composed of sandy silt loam with brown to light brown (10YR 3/2 to 10YR 3/3)
matrix colors. The upland test plot did not meet hydric indicators.

Delineation Report 2 June 16,2020
HYDROLOGY
Hydrology was observed in Wetland A during the June 1, 2020 site visit as saturation to the soil
surface. Wetland A is situated on sloping terrain and is likely primarily fed by groundwater
seepage.
There is a stream channel untyped by DNR mapped offsite east of the lot (Figure 6). Due to
property ownership, the channel was not observed during the site visit. SalmonScape, an online
tool that maps fish distribution and fish passage features in Washington, indicates fish blockages
near NE Anchor Way where the channel eventually drains, and it does not indicate salmonid
species in the reach adjacent to the wetland. Therefore, it is reasonable to assume that the
stream meets the definition of a Type Ns water. Additionally, it is mapped over 300 feet east of
the lot and would not have a buffer extending onsite.
NATIONAL WETLAND INVENTORY
The National Wetlands Inventory (NWI) map indicates the presence of a riverine wetland in the
same location as the untyped stream (Figure 5). The findings of the ELS site visit identified
Wetland A at the east lot boundary. The NWI maps should be used with discretion because they
are used to gather general wetland information about a regional area and therefore are limited in
accuracy for smaller areas because of their large scale.
MASON COUNTY CRITICAL AREAS
The Mason County Critical Areas map (MC 2020) indicates the presence of low geologic hazard
across the lot and the untyped stream offsite to the east (Figure 6). MCCA does not indicate the
presence of wetland onsite, however, ELS biologists identified Wetland A at the east end of the
lot.
CONCLUSIONS
WETLAND CATEGORIZATION
Wetland A is in a sloping system along the east edge of the lot and drains south via the Type Ns
channel. It eventually drains into Hood Canal after crossing several roads with blockages.
Wetland A was rated according to Washington State Wetlands Rating System for Western
Washington-2014 Update (Rating System) (Hruby 2014) (Appendix B). The rating is summarized
in Table 1 below.

CRITICAL AREA REGULATIONS
The MCC 8.52.110 specifies wetland buffers based on the wetland category, the intensity of land
use proposed, and the habitat scores. The proposed land use is high intensity because it is a
single-family residential development on less than one acre. The wetland scored 5 points for
habitat which was previously considered a moderate score. In July 2018, Ecology released new
guidance which made 5 points low habitat function. Therefore, the buffer is based on a "low
habitat" functions despite having 5 points. An additional 15-foot building and impervious surface
setback is specified from the edge of the wetland buffer.

MCC 8.52.110 also specifies that wetlands having low habitat scores can use moderate intensity
land use buffers under the provisions in Table 8.52.110 G. MCC also specifies provisions that
allow the buffer to be averaged under certain parameters. These criteria are addressed below.
MCC 8.52.11O(2)(d)(i) For wetlands that score moderate or high for habitat (five points or more
for the habitat functions), the width of the buffer may be reduced to that required for moderate-
intensity impacts provided that:
(a) A relatively undisturbed, vegetated area corridor at least one hundred feet wide is
protected between the wetland and any other priority habitats as defined by the
Washington State Department of Fish & Wildlife. Protection of the entire corridor shall be
assured by a conservation easement or equivalent legal protection;
There are no mapped priority habitats in the vicinity of the wetland; however, the
wetland is in a relatively undisturbed corridor that will not be disturbed by the project.
(b) Measures to minimize the impacts of the land use shall be applied. Examples of these
measures are shown in Table 8.52.11O(G)

Compliance with the above provisions allows the project to utilize the moderate intensity land
use buffer of 40 feet (Figure 2).
MCC 8.52.110(2)(d)(ii) Averaging to allow reasonable use of a parcel may be permitted when all
of the following are met:
(a) There are no feasible alternatives to the site design that could be accomplished without
buffer averaging;
The 0.24-acre lot is too constrained to accommodate a reasonable single-family residence
and septic drainfield without averaging.
(b) The averaged buffer will not result in degradation of the wetland's functions and values as
demonstrated by a report from a qualified wetland professional;
The wetland and buffer will not be negatively impacted by averaging. The slope will serve
to protect the wetland as well as native forest vegetation.
(c) The total buffer area after averaging is equal to the area required without averaging,and
The project proposes to reduce the buffer in one area by 313 square feet and increase the
buffer in another area by 313 square feet. The amount of buffer onsite is maintained.
(d) The buffer at its narrowest point is never less than 314 of the required width.
Using a 40 foot buffer, 3/4 of that width is 30 feet. The buffer is 32 feet at its narrowest
with the buffer averaging plan. In addition,the 15 foot building and impervious setback is
observed (Figure 10).

Plot 1 was conducted. It is located
at the edge of the wetland, between
boundary flags A-3 and A-4. The
area was characterized by over-
ram- hanging cover of western hemlock,
lady fern, mixed organic and mineral
soil, and saturation to the soil sur-
face.
Photo 6 was taken of the area where Test
Plot 2 was conducted. It is located
on the upland slope outside bound-
ary flags A-3 and A-4. This area is
characterized by mixed deciduous
and coniferous tree cover and sword
1 ` ferns. The soil did not meet hydric
indicators and there was no pres-
ence or evidence of wetland hydrol-
ogy. This area was therefore deter-
mined to be upland.

HGM Classification of Wetlands in Western Washington
For questions 1-7 the criteria described must apply to the entire unit being rated.
q � pP Y g
If the hydrologic criteria listed in each question do not apply to the entire unit being rated,you
probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in
questions 1-7 apply,and go to Question 8.
1. Are the water levels in the entire unit usually controlled by tides except during floods?
NO-go to 2 YES-the wetland class is Tidal Fringe-go to 1.1
1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt(parts per thousand)?
NO -Saltwater Tidal Fringe (Estuarine) YES- Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO-go to 3 YES-The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
_The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
_At least 30% of the open water area is deeper than 6.6 ft(2 m).
NO -go to 4 YES-The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
The wetland is on a slope (slope can be verygradual),
The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
The water leaves the wetland without being impounded.
NO-go to 5 MS-The wetland class is Slope
NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and
shallow depressions or behind hummocks (depressions are usually<3 ft diameter and less than 1 ft
deep).
5. Does the entire wetland unit meet all of the following criteria?
The unit is in a valley,or stream channel,where it gets inundated by overbank flooding from that
stream or river,
The overbank flooding occurs at least once every 2 years.
Wetland Rating System for Western WA:2014 Update 3
Rating Form-Effective January 1,2015
Wetland name or number Schooner
NO-go to 6 YES-The wetland class is Riverine
NOTE:The Riverine unit can contain depressions that are filled with water when the river is not
flooding
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the
surface,at sometime during the year? This means that any outlet, if present, is higher than the interior
of the wetland.
NO -go to 7 YES-The wetland class is Depressional
7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank
flooding? The unit does not pond surface water more than a few inches. The unit seems to be
maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural
outlet.
NO-go to 8 YES-The wetland class is Depressional
8. Your wetland unit seems to be difficult to classify and probably contains several different HGM
classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small
stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY
WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT
AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the
appropriate class to use for the rating system if you have several HGM classes present within the
wetland unit being scored.
NOTE: Use this table only if the class that is recommended in the second column represents 10% or
more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2
is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the
total area.
HGM classes within the wetland unit HGM class to
being rated use in rating
Slope + Riverine Riverine
Slope+ Depressional Depressional
Slope + Lake Fringe Lake Fringe
Depressional + Riverine along stream Depressional
within boundary of depression
Depressional + Lake Fringe Depressional
Riverine+ Lake Fringe Riverine
Salt Water Tidal Fringe and any other Treat as
class of freshwater wetland ESTUARINE
lfyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have
more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the
rating.
