SUBJECT: Wetland Reconnaissance for Bilti Short Plat
19116 - 116th Ave. SE (Parcel 619840-0161), City of Renton, WA
Dear Simion:
On October 8, 2015 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 site review.
The western portion of the site is developed with a single-family residence and
associated detached out-building. The remainder of the property consisted of a
mowed lawn that slopes gently down from west to east. Vegetation on the site
included grasses, dandelion (Taraxacum officinale), and cats ear (Hypochaeris
radicata). The undeveloped area off-site to the north consisted primarily of scattered
trees and an understory of monotypic Himalayan blackberry (Rubus armeniacus).
No hydrophytic plant communities were observed on or adjacent to the site.
The entire property is mapped by the Natural Resources Conservation Service
(NRCS) as Alderwood Gravelly Sandy Loam, a non-hydric soil. Borings taken
throughout the site revealed high-chroma dry non-hydric soils and there was no
evidence of prolonged soil saturation or ponding anywhere on the property.
Conclusion
No wetlands were identified on or adjacent to the site during the field investigation.
