(19) Wetland Assessment – Kennydale Gateway
Vulcan Real Estate
Renton, Washington
Wetland Assessment
No wetlands were identified on the Site, and there is no proposed development within adjacent
wetlands or their buffers. Two areas of evident surface water were observed in the southern portion of
the property. These areas are the result of soil compaction resulting from trailer and equipment
storage, as well as many years of vehicular traffic. Puddles are not regulated under the Clean Water Act
(U.S. Army Corps of Engineers 2015).
One wetland is mapped within the May Creek Trail Park. We evaluated and flagged the existing limits of
this wetland and found it to be smaller than presented on the City’s GIS database. We rated the
wetland based on RMC 4-3-090.D.2.d.ii. The wetland scored 16 points for Water Quality Functions, 10
points for Hydrologic Functions, and 15 Points for Habitat Functions. The Total Score for Functions is 41,
which qualifies the wetland for a Category III rating. Category III wetlands located within a shoreline
jurisdiction, and having a Habitat Score less than 20, have a 75-foot standard buffer. Applying this
buffer to the wetland boundary as mapped by the City of Renton (not Talasaea’s smaller wetland
boundary) clearly shows that the buffer does not extend onto the Site.
Project Description
The Site will be redeveloped with three apartment buildings providing 378 units of apartments. Access
to the Site will be provided by a new roundabout constructed off Lake Washington Boulevard N at the
northwestern corner of the multi-family residential development.
Multi-Family Residential Development. The multi-family residential development (Residential
Development) will consist of a three-story “wrap” apartment development with courtyards (Figure 5).
The development will occupy approximately 255,379 sf (5.9 acres) of the total Site area (approximately
7.76 acres). A multi-story concrete cast-in-place parking garage will be wrapped by a wood-framed
apartment construction. The purpose of this particular design is to “hide” the parking structure to be
more aesthetic visually from Lake Washington Boulevard N. The Residential Development will provide
approximately 378 units of studio, one-bedroom, and two-bedroom configurations. Access to the
apartments will be provided by air-conditioned corridors. The upper floors of the apartments will have
elevator access. The Residential Development will also “wrap” around a central courtyard area. Five
additional courtyards will be provided around the periphery of the apartment complex: two will be

associated with Building 1 (northernmost proposed building), one associated with Building 2
(southeastern corner of the site), and three associated with Building 3.
An access road along the eastern and southern portions of the proposed development will provide
parking stalls as well as fire and emergency access to the eastern and southern portions of the complex.
The access road will connect to the main entrance off of Lake Washington Boulevard N and will
terminate at the Site’s southwestern corner, also off of Lake Washington Boulevard N. Access to this
road from Lake Washington Boulevard N will be restricted by removable bollards.
Retail Space. The retail space will be provided at the southwestern corner of Building 1. The retail space
will be approximately 1,550 sf in size. Access to the retail space, including fire and emergency services,
will be provided by the main access road off of Lake Washington Boulevard. Eight parking stalls will be
provided for the retail space.
Vegetative Cover
The wetland located adjacent to the Site is dominated by a mix of FACW, FAC, and FACU species
including Corylus cornuta, Alnus rubra, Populus balsamifera, Acer macrophyllum, Lonicera involucrata,
Rubus spectabilis, Oemleria cerasiformis, Polygonum sachalinense, Ranunculus repens, and Epilobium
ciliatum.
