SUBJECT: Wetland Reconnaissance for Wilson Property (Parcel 312305-9125)
720 So. 551h Street, Renton, WA
Dear Steve:
On January 15, 2009 1 conducted a wetland and stream reconnaissance on the
subject property and the adjacent new 50 -foot wide access easement utilizing the
methodology outlined in the 1997 Washington State Wetlands Identification and
Delineation Manual. No wetlands or streams were identified on or immediately
adjacent to the property or the new access easement during the reconnaissance.
The south-central portion of the subject property is currently developed with an
existing single-family residence and associated maintained lawn area. The
remainder of the property consists of a mostly coniferous forest that generally slopes
moderately down from east to west.
Vegetation on the site included western red cedar (Thuja plicata), Douglas fir
Pseudotsuga menziesh), big -leaf maple (Acer macrophyllum), hazelnut (Corylus
comuta), Indian plum (Oemleda cerasiformis), snowberry (Symphoricarpos albus),
tall Oregongrape (Mahonia aquifolium), Himalayan blackberry (Rubes discolor),
trailing blackberry (Rubes ursinus), sword fern (Polystichum munitum), and English
ivy (Hedera helix). The plant community within the undeveloped new access
easement consisted of a mix of trees and brush including black cottonwood (Populus
trichocarpa), big -leaf maple, Himalayan blackberry, snowberry, sword fern, and
English ivy. No hydrophytic plant communities were observed on the site.
Barings taken throughout the property revealed high chroma non -hydric soils and
there was no observation or evidence of prolonged soil saturation.
