Hello Jill,
On November 1, 2022, I emailed you to let you know that I had some questions regarding the regulatory
status of the area denoted as Feature G at the Sounders FC Center at Longacres project site. I’ve
included the email to you as an attachment for the benefit of those copied to this email.
I was able to visit the site on November 8, 2022, to observe the conditions within and around Feature
G. I’ve also reviewed most of the materials submitted to the city for the Sounders project, along with
other widely available desktop resources.
The following submitted materials are most relevant to my review:
· Talasaea Consultants, Inc.’s Critical Areas – Existing Conditions Letter Report dated April 29,
2022 (Report)
· Otak, Inc.’s Peer Review Memorandum dated June 9, 2022 (Memo)
· Talasaea Consultants, Inc.’s Critical Areas Report and Conceptual Mitigation Plan dated October
7, 2022 (Mitigation Plan)
· NV5’s ALTA/NSPS Survey – Boeing Longacres Property dated October 14, 2021 (Survey)
· Existing Conditions Survey Map of the Longacres Property Unknown author, undated
In the Report, Talasaea determines that Feature G is not a regulated wetland per Renton’s Municipal
Code, and Otak concurred with this determination in the Memo.
Ecology Review of the Regulatory Status of Feature G
Washington State’s definition of a wetland (see RCW 90.58.030(2)(h)) is as follows:
"Wetlands" means areas that are inundated or saturated by surface water or groundwater at a
frequency and duration sufficient to support, and that under normal circumstances do support, a
prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally
include swamps, marshes, bogs, and similar areas. Wetlands do not include those artificial wetlands

intentionally created from nonwetland sites, including, but not limited to, irrigation and drainage
ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and
landscape amenities, or those wetlands created after July 1, 1990, that were unintentionally created as a
result of the construction of a road, street, or highway. Wetlands may include those artificial wetlands
intentionally created from nonwetland areas to mitigate the conversion of wetlands.
The City of Renton’s definition of areas not considered wetland is essentially the same as the last
sentence in the paragraph above (see RMC 4-3-050B).
It is important to note that a feature has to be artificial in nature, intentionally created/constructed, and
created in non-wetland (i.e., in upland) to not be considered a regulated wetland under state
law. Feature G is artificial in nature and was created in non-wetland but was not intentionally
created/constructed. Since Feature G does not meet all of the characteristics of a non-wetland area,
as defined in state law, Ecology’s Shorelands and Environmental Assistance (SEA) Program considers
Feature G to be a state regulated wetland.
Ecology’s rationale for this determination is as follows:
· Ecology is in agreement with the Report that there is no substantive evidence to indicate the
presence of wetland within or in the immediate vicinity of Feature G prior to the construction
activity on the Longacres properties in the late 1990’s.
· Sample Point TP-G1 in the Mitigation Plan, which is located within Feature G, meets wetland
criteria (vegetation, soils, and hydrology). Ecology confirmed the presence of wetland
conditions within Feature G during the November 8, 2022 site visit, and Ecology assumes that
both Talasaea and Otak agree that Feature G currently meets wetland criteria. If this is not the
case, please let me know and we can discuss potential steps to take that might support a
different conclusion.
· Photo 4 in the Report is a low elevation aerial of Feature G. No stormwater inlets or outlets can
be observed within or around Feature G in the photo, and the lack of any direct or designed
stormwater input into Feature G was confirmed during Ecology’s November 8, 2022 site visit. As
such, there is no evidence on the ground to indicate that Feature G currently serves any
intentional stormwater management function.
· The Report provides a detailed account of the history of the activity within and around Feature
G over the past 40 years, and it cannot be disputed that a sedimentation basin was located in
the same general area as the current Feature G in the late 1990’s. The snip below is taken from
the Report; it is a high resolution aerial photo from the late 1990’s that clearly shows this
feature:
It is also just as apparent that this sedimentation basin was intended to be temporary. The snip
below is a 2000 aerial photo of Feature G and vicinity, which shows that the sedimentation basin was
filled in:
In the over 20 years since the area within and around Feature G was filled in, wetland
characteristics have developed within Feature G. There is no evidence to indicate that this
wetland was intentionally created; it appears that the wetland conditions within Feature G have
developed inadvertently and naturally over time.
Additional evidence to support that Feature G currently serves no stormwater management
function can be found in the Survey. The snip below is the portion of the Survey around Feature
G:
The Survey snip above shows the wetland boundary of Feature G, presumably as delineated by
NV5 in March 2021, along with the existing stormwater infrastructure in the vicinity of Feature
G.
There are two stormwater lines near Feature G. The line to the south collects water from areas
to the south and east of Feature G and conveys it into the feature called Pond B in the Report;
there is no direct connection between this line and Feature G. The line to the east and north of
Feature G is denoted with the abbreviation (ABOND), which might be an abbreviation for
abandoned. The structure at the end of this line has a callout that says “Per As-Built Could Not
Locate”.
Taking into account that neither the surveyors in 2021 nor Ecology in November 2022 were able
to find any evidence of the existence of this stormwater line, it is reasonable to assume that this
stormwater line was constructed to convey water into the temporary sedimentation ponds
during the late 1990’s activity on the Longacres Park property and was abandoned once the
sedimentation ponds were filled in.
Next Steps
Since Feature G is considered a state regulated wetland and will be impacted by the proposed project,
the applicant will need to apply for federal and/or state permits/certifications. Please contact me with
any specific questions about the state wetland permitting process; contact the U. S Army Corps of
Engineers for specific questions relating to the Federal wetland permitting process.
Feature G will need to be rated. I’ve attached my attempt to rate Feature G to this email; if there is
general agreement that this rating is appropriate, feel free to use it. Let me know if there are any
specific questions regarding my rating. I can provide the supporting figures for the rating upon request.
Lastly, since the proposed project will impact Feature G, the current wetland mitigation plan for the
project will need to be updated to account for and appropriately compensate for the loss of this wetland
area.
Please feel free to contact me with any questions regarding this email.
