Subject: Wetland Determination for 9.96-Acre NE Roy Boad Road Parcel
Tax Parcel# 1123282300011,Belfair,Mason County,Washington
Dear Mr. Mauerman:
A wetland determination study was performed at your request on September 7,2018 for the above
9.96-acre parcel on NE Roy Boad Road in the Belfair UGA of unincorporated Mason County,
Washington. The property is situated in the SW'/4 NW'/4 of Section 28,Township 23N,Range 1
West, Willamette Meridian. The parcel is being considered for construction of multi-dwelling
apartment buildings.
The largely wooded,undeveloped parcel is bounded by SR3 along its eastern boundary. Roy Boad
Road bisects the property in a north-south direction in the western third of the parcel. The east
portion of the property was logged several years prior. The land descends approximately 100 feet
from the from the SR3 right-of-way in the east third of the property,where it transitions to moderate
and low gradient topography in the forested center and west portion of the site.
The vegetation,soils,and hydrology of the site were examined for the presence of wetlands using the
criteria of the Western Mountain, Valleys and Coast Regional Supplement (WMVC-Version 2)to
the U.S. Army Corps of Engineers Wetland Delineation Manual. The eastern portion of the property
was observed to be sloped,well-drained land with strongly non-hydrophytic vegetation. The low-
gradient portion of the parcel west of Roy Boad Road appears somewhat moister and was examined
closely for indicators of jurisdictional wetland. Two wetland data plots(enclosed)were established
in suspect areas along the west property boundary.
The entire parcel is mapped in the Soil Survey of Mason County, Washington(SCS 1960)as having
non-hydric soils. The upper slopes of the eastern portion of the property are mapped as Alderwood
gravelly sandy loam 15-30%slopes and Everett very gravelly sandly loam 8-15%. Most of the center
and west portion of the property is mapped as Indiianola sandy loam,0-5%slopes. The extreme west
edge of the property is identified as Saxon silt loam, 5-15%slopes. Overall,soils appear deep and
well drained. No signs of hydric soil conditions such as low chroma or color depletion,redox
features,etc.were observed anywhere on the property.

The east portion of the property supports young Douglas fir,salal,sword fern,beaked hazelnut,
ocean spray,Oregon grape,trailing blackberry, Scot's broom and other non-hydrophytic vegetation
adapted to well-drained conditions.
A wetland data plot near the northwest corner of the property(DPI)is typical of the lower areas west
of Roy Boad Road. The plant community is dominated by mixed hydrophytic and non-hydrophytic
vegetation including bigleaf maple,red alder,western red cedar,sword fern,Indian plum,
salmonbery,Oregon grape,salal,stinging nettle, lady fern and trailing blackberry,with Himalayan
blackberry occurring along the road and near clearings on adjacent property. The soil is deep,well
colored(chroma 4)sandy loam, and completely lacking in hydric soil indicators. Primary and
secondary indicators of wetland hydrology are completely lacking. It is concluded that the on-site
area west of Roy Boad Road is non-wetland.
A catch basin on the east side of Roy Boad Road on the south property line collects storm water from
the street and developed properties south of the subject property. The catch basin directs the water
via culvert to the west side of the road where it is released onto the subject parcel. The culvert
empties into an approximately 60-foot long swale with no outlet that is surrounded by non-wetland
vegetation. The catch basin was dry when examined on September 7,2018. During storm events
released water appears to infiltrate into the ground within the on-site swale,and does not contribute
to any nearby water features.
A suspect wetland area was noted immediately off-site near the center of the west property line
(DP2). The small(100-120 sq.ft.)depression is sparsely vegetated,and surrounded by red alder,
salmonberry,lady fern,creeping buttercup, lady fern and sword fern and stinging nettles. The soil is
marginally non-hydric,with a dark sandy loam surface layer 6 inches thick,chroma 3 sandy loam
with no redox features from 7-15 inches,and chroma 3 subsoil horizons with numerous redox mottles
below 15 inches. This isolated depression may be seasonally wet,but it does not meet the mandatory
hydric soil criteria for jurisdictional wetland. It is also smaller than the minimum Mason County size
threshold(1,000 sq.ft.)for regulated wetlands which are not part of mosaic systems and are not
associated with riparian areas.
Low-lying forest to the west was scanned to a distance of 250 feet from the property with no other
suspect areas observed. The National Wetland Inventory map of the area(Figure 1,enclosed)shows
a seasonally flooded wetland approximately 820 feet west of the subject parcel near the Old Belfair
Highway. The extent of the wetland as shown on the NWI mapping appears accurate when
compared to historic aerial photos available on Google Earth. The off-site wetland and surroundings
are reportedly owned by the non-profit Hood Canal Conservation Group and are referred to as the
Nance Property.
The maximum buffer width for wetlands in Mason County is 300 feet(8.52.110,Mason County
Code). Accordingly,the Nance property wetland to the west appears to be without regulatory
significance for the subject property.

P.3
No streams were observed on or near the Roy Boad Road parcel. Washington Dept. of Natural
Resources stream typing maps were referenced to check for documented streams in the project
vicinty. The Forest Practics Application Mapping Tool GIS map for the area is shown in Figure 2.
The nearest documented stream is approximately 740 feet northwest of the subject parcel(unknown
stream type per WDNR). The maximum Mason County stream buffer width is 150 feet;therefore,
the stream to the northwest is without regulatory significance to this property.
In summary,no regulated wetlands or streams were identified on or within 300 feet of the subject
parcel. The storm water released onto the property from Roy Boad Road does not support any on-
site wetland or drainages. A small off-site depression near the west property line does not appear to
be a jurisdictional wetland by federal,state or local definitions. It is concluded that the 9.96-acre
Roy Boad Road property is without any encumbrences from wetlands,streams or their associated
buffers.
