SUBJECT: Wetland and Stream Reconnaissance for 13016 – 156th Ave. SE Renton, WA (Parcels 366450-0185 an -0205)
Dear Dan: On January 21, 2020 I conducted a wetland and stream reconnaissance on the
subject property utilizing the methodology outlined in the May 2010 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0). No wetlands or streams were identified on or adjacent to the property during the field investigation.
The western portion of the site on Parcel 366450-0205 is currently developed with a single-family residence and associated yard. The remainder of this parcel is undeveloped and consisted of a mixed upland forest and brush patches that included Douglas fir (Pseudotsuga menziesii), western red cedar (Thuja plicata), Himalayan blackberry (Rubus armeniacus), English holly (Ilex aquilinum), sword fern
(Polystichum munitum), and English ivy (Hedera helix). Parcel 366450-0185 consisted primarily of upland pasture and fill areas. Common plant species were generally typical of disturbed more mesic environments and
included a variety of grasses, cats ear (Hypochaeris radicata), English plantain (Plantago lanceolata), and oxeye daisy (Chrysanthemum leucanthemum). No hydrophytic plant communities were observed on or adjacent to the property.
Borings taken throughout the site revealed high chroma non-hydric soils and there
was no evidence of ponding or prolonged soil saturation anywhere in the vicinity of the property.

Conclusion No wetlands or streams were identified on or immediately adjacent the site. This determination is based on a field investigation during which no hydrophytic plant
communities, hydric soils, or evidence of wetland hydrology or channels were observed. If you have any questions regarding the reconnaissance, please give me a call.
