RE: Wetland and Stream Reconnaissance – 3601 Lincoln Avenue NE, Renton, WA
Wetland Resources, Inc. (WRI) performed a site investigation on April 7, 2025, at the 1.10-acre
property located at the address referenced above. The King County tax identification number for
the subject parcel is 3345700230. The site is located within the May Creek sub-basin of the Cedar
River/Lake Washington watershed, Water Resource Inventory Area 8. The Public Land Survey
System (PLSS) locator for this parcel is Section 32, Township 24, Range 5E, W.M.
The parcel is developed with a single-family residence, a shop/garage, and driveway. Vegetation
near the house is maintained landscaping and lawn and a row of trees is present along the western
edge of the parcel. The site is relatively flat, with a west-facing slope beginning near the western
property line. Surrounding land use is generally single-family residential. May Creek, May Creek
Park, and associated undeveloped open space is located to the west/southwest of the parcel.
The purpose of this report is to present information related to wetlands and streams on and in the
vicinity of the subject parcel. Landslide, erosion, and other geological hazard areas are beyond the
scope of this report.
REVIEW OF EXISTING INFORMATION
Prior to conducting the site investigation, public resource information was reviewed to gather
background information on the subject property and the surrounding area regarding wetlands,
streams, and other critical areas. These sources include the following:
• United States Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI): This
resource maps a riverine feature (May Creek) to the west, on the west side of Jones Avenue NE.
• USDA/NRCS Web Soil Survey: The Web Soil Survey indicates that the property is underlain
by Alderwood gravelly sandy loam, 8 to 15 percent slopes.
• WDFW Priority Habitat and Species (PHS) Interactive Map: The PHS Interactive Map maps
May Creek off site to the west. This stream is listed as habitat for Chinook salmon, sockeye
salmon, coho salmon, and steelhead trout.

• King County iMap: King County depicts May Creek to the west of the site, on the west side of
Jones Avenue NE.
• City of Renton interactive GIS map: This resource maps May Creek and an associated wetland
over 300 feet off site to the west. Another wetland is mapped approximately 100 feet to the
south of the property. Landslide and erosion hazard areas are shown in the western portion of
the site. Geologically hazardous areas are outside of the scope for this report.
METHODOLOGY
The Washington State Department of Ecology document Determining the Ordinary High Water Mark
for Shoreline Management Act Compliance in Washington State (Anderson et al. 2016) was used to determine
the presence of any streams on the subject site.
Wetland areas were determined using the routine determination approach described in the Corps
of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987) and the Regional Supplement
to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version
2.0) (U.S. Army Corps of Engineers 2010). Under the routine methodology, the process for making
a wetland determination is based on three steps:
1) Examination of the site for hydrophytic vegetation (species present and percent cover);
2) Examination of the site for hydric soils;
3) Determining the presence of wetland hydrology
The wetland identified was rated pursuant to the Washington State Wetland Rating System for Western
Washington: 2014 Update as required by Renton Municipal Code (RMC) 4-3-050G.9.c. Please note
the wetland ratings presented in this report are based on preliminary information and are subject
to change if the wetlands are formally delineated.
FINDINGS
On-site vegetation near the residence includes Japanese maples, wisteria, rhododendrons, and
other installed landscaping plants. Native vegetation observed near the western boundary of the
site includes big leaf maple (Acer macrophyllum; FACU), western hemlock (Tsuga heterophylla; FACU),
snowberry (Symphoricarpos albus; FACU), and sword fern (Polystichum munitum; FACU). Sampled soils
were dry and generally very dark brown (10YR 2/2) in the upper layer and dark brown (10YR
3/3) in the second layer. Soil texture was typically loam or sandy loam across the site. Given the
lack of hydrophytic vegetation, wetland hydrology, or hydric soil indicators, there are no wetland
areas present on the property. No flowing water, channels, scours, or sorted material were observed
on the site; therefore, there are no streams on the site.
Off-site Wetlands and Streams
May Creek and an adjacent wetland are approximately 320 feet to the west/southwest of the site.
Since May Creek and the adjacent wetland are over 300 feet from the subject property, these
features do not cast a buffer onto the parcel. Shoreline jurisdiction would extend 200 feet from the
edge of these features and per the City of Renton’s GIS map information, the shoreline
environment associated with May Creek terminates west of the site.

A second wetland mapped by the City of Renton is present a little over 100 feet to the south the of
property. This wetland (Wetland A) was evaluated and is discussed below.
Wetland A (Off-site)
HGM Category: Slope
Wetland Rating Category: III
City of Renton Buffer: 100 feet
Wetland A is a located approximately 100 feet south of the subject property along a sloped area
east of Jones Avenue NE. As this wetland is off-site, information about this wetland was gathered
from aerial imagery, publicly available resources like the City of Renton interactive map, and
observations from adjacent rights-of-way.
Vegetation in Wetland A includes black cottonwood (Populus balsamifera; FAC), red alder (Alnus
rubra; FAC), Himalayan blackberry (Rubus armeniacus; FAC), horsetail (Equisetum sp.), and reed
canarygrass (Phalaris arundinacea; FACW). Saturation and standing water were observed at the toe
of the slope, along the west side of Jones Avenue NE. As the wetland is located off of the property,
soils within the wetland area were not sampled.
Wetland A is a Category III wetland with a moderate habitat score. Per RMC 4-3-050G.2, this
wetland requires a 100-foot buffer and a 15-foot building setback from the wetland buffer.
USE OF THIS REPORT
This Wetland and Stream Reconnaissance Report has been prepared for JKM Holdings, LLC to
assist with identifying on-site and nearby critical areas as required by the City of Renton. This
report is based largely on readily observable conditions and, to a lesser extent, on readily
ascertainable conditions. No attempt has been made to determine hidden or concealed conditions.
The laws applicable to critical areas are subject to varying interpretations and may be changed at
any time by the courts or legislative bodies. This report is intended to provide information deemed
relevant in the applicant's attempt to comply with the laws now in effect.
This report conforms to the standard of care employed by ecologists. No other representation or
