SITE DESCRIPTION
On September 12, 2016 Acre Environmental Consulting, LLC visited the approximate 4.54-acre
site located at 13833 156th Avenue SE in the City of Renton, Washington. The site is further
located as a portion of Section 14, Township 23N, Range 5E, W.M. The parcel number for this
property is 146340-0060. The purpose of this site visit was to locate and assess regulated
critical areas on and adjacent to the subject site. Surrounding land use is comprised of single-
family residential development and pasture. There are no wetlands or streams located on or
adjacent to the subject site.
Acre Environmental Consulting, LLC used the routine methodologies described in the
Washington State Wetlands Identification and Delineation Manual (Washington State
Department of Ecology Publication #96-94, March 1997) to make a determination regarding the
presence of regulated wetlands on the site. In addition, Acre Environmental Consulting, LLC
evaluated the site using the U.S. Army Corps of Engineers Wetland Delineation Manual
produced in 1987 and the U.S. Army Corps of Engineers Regional Supplement to the Corps of
Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region
produced in May 2010.
Access to this site from the east via 156th Avenue SE located along the eastern border of the
property. This site has a gentle west aspect. A single-family residence and associated
infrastructure are located in the east-central part of the property. The rest of the site is
occupied by actively grazed pasture with scattered big leaf maple (Acer macrophyllum, FacU).
Typical vegetation in the pasture is represented by small patches of Himalayan blackberry
(Rubus armeniacus, Fac) with colonial bentgrass (Agrostis capillaris, Fac), velvetgrass (Holcus
lanatus, Fac), tall fescue (Schedonorus arundinaceus, Fac), creeping buttercup (Ranunculus
repens, Fac), common Tansy (Tanacetum vulgare, FacU), purple dead-nettle (Lamium
purpureum, Nol/ Upl), English plantain (Plantago lanceolata, FacU), and white clover (Trifolium
repens, Fac). Typical soils on the site have a Munsell color of dark brown (10YR 3/3), with a
texture of sandy loam from 0 to 18 inches below the surface. Soils were dry throughout the
profile during our September 12, 2016 site investigation.
No wetlands or streams are located on the subject site, and there are no adjacent wetlands or
streams that would extend buffers on to the subject site.
