<br /> 2.3.2 Stream A
<br /> Stream A is a tributary to Swamp Creek, within the upper Swamp Creek sub-basin (WRIA 8).
<br /> Within the subject site, Stream A is an open channel flowing north to south in the western
<br /> portion of the property. The stream channel enters the site via a roadway culvert at the northern
<br /> property boundary, and exits the site via another culvert at the southern property boundary.
<br /> Between the southern property boundary and its conveyance point with Swamp Creek, Stream A
<br /> almost exclusively remains within an underground stormwater system.

<br /> 2.3.3 Non-wetland Area
<br /> The upland or non-wetland portion of the site is dominated by disturbed scrub-shrub and
<br /> emergent vegetation, with several mature and immature trees scattered throughout. Non-wetland
<br /> vegetation is represented by Douglas fir (Pseudotsuga menziesii; FACU), western hemlock (Tsuga
<br /> heterophylla; FACU), red alder (Alnus rubra; FAC), poplar species (Populus spp.), Himalayan
<br /> blackberry (Rubus armeniacus; FAC), sword fern (Poystichum munitum; FACU), stinging nettle (Urtica
<br /> dioica; FAC), reed canarygrass (Phalaris arundinacea; FACW), and common pasture grasses.
<br /> The soils within the non-wetland area adjacent to the wetland were dry at the time of inspection.
<br /> Sampled soils were very dark grayish brown (10YR 3/2) to a depth of 6 to 8 inches below the
<br /> surface, and ranged from dark olive brown (2.5Y 3/3) to dark yellowish brown (10YR 3/4) to a
