RE: My client Strada da Valle LLC’s proposed U.S. Bank Expansion Project located at 2500
East Valley Road
Requests for (1) your waiver of a habitat/wildlife assessment pursuant to RMC 4-3-
050F.7.a, (2) your waiver of the wetland assessment report requirement pursuant to
RMC 4-3-050F.7.c, and (3) your determination pursuant to RMC 4-3-050B.1.g that
the Wetland Critical Areas regulations of RMC 4-3-050 do not apply to the
proposed expansion project activity/project site
Dear Chip:
Concerning the proposed minor expansion of part of the north end of my client Strada da
Valle LLC’s (“Strada’s”) existing single-story office building located at 2500 East Valley Road,
and in follow-up to a recommendation from Planning Director Jennifer Henning to Associate
Planner Angelea Weihs that Ms. Weihs conveyed to me by phone in regard to the third of the
three above-referenced requests that I address in this letter to you, I am writing on Strada’s
behalf to make the following three requests:
(1) A request for your waiver of a habitat/wildlife assessment pursuant to
RMC 4-3-050F.7.a because the proposed project activities are neither (a)
located within or abutting a critical habitat defined in RMC 4-11-030 nor
(b) located adjacent to a critical habitat;
(2) A request for your waiver of the wetland assessment report requirement
pursuant to RMC 4-3-050F.7.c because (a) no wetlands exist on the
subject parcel and (b) an extensive segment of the existing concrete-paved
parking lot and drive aisle that exists between the off-site wetland in the
Valley Freeway’s west right-of-way margin and the proposed building
addition is a barrier that is proposed to be retained; and
(3) A request for your determination that, pursuant to RMC 4-3-050B.1.g. the
Wetland Critical Areas regulations of RMC 4-3-050, the Wetland Critical

Areas regulations of RMC 4-3-050 do not apply to the proposed
activity/project site of the proposed expansion because that above-
mentioned existing off-site wetland is separated from the upland proposed
activity/project site area by the pre-existing, intervening, and lawfully
created (a) concrete-paved parking lot and drive aisle and (b) the existing
stormwater detention and conveyance system, which together prevent
delivery of functions from the subject upland area to the wetland.
Let me begin by explaining background circumstances of the proposed U.S. Bank
Expansion project on the subject parcel and an accompanying critical areas determination report
concerning an off-site wetland and concerning the lack of any critical habitat on, abutting, or
adjacent to the subject property.
Background
Summary of the Proposed Expansion Project
The U.S. Bank expansion project is a proposed ±2,673-square-foot building addition that
is proposed to consist primarily of a high-security two-bay parking garage1 along part of the
north end of the Strada’s ±28,065-square-foot single-story office building that is located on a
3.08-acre parcel of land referred to as Lot 3 of the Strada da Valle Short Plat (City of Renton
File No. LUA-02-042-SHPL, King County Recording No. 20110112900004). The existing
building and site improvements were completed in 1991. Upon their completion, the City issued
a Certificate of Occupancy dated August 20, 1991. (A copy of that certificate is attached as
Attachment 1.)
Attachment 2 is an exhibit created from an overall parcel site plan (Sheet A1.0) prepared
by Cornerstone Architectural Group on which I had one of my legal assistants add some color
outlining, shading, and labeling. Attachment 2 depicts existing site improvements throughout
Lot 3 (outside of the proposed addition’s project site area) in addition to the following:
(1) The layout of the proposed addition to the building [an addition that is
proposed to be located in (a) an area of existing concrete-paved parking
stalls, (b) the southern part of the associated existing concrete-paved
driveway that currently runs east-to-west through the existing parking lot
to the north of the existing building, (c) an existing landscape planting
1 Nearly all the proposed building addition’s space (a floor plate of ±2,411 square feet) will be constructed for
use as a high-security two-bay truck garage for pickups from and deliveries to the existing building to be
handled within the garage when the overhead garage doors are shut. A ±252-square-foot portion of the
addition to the south of the parking garage floorplate (a portion of the addition that will lie beneath what is
currently much of the existing building’s north eave at the interface of the addition to the existing building)
will slightly increase the size of the space in the building available for office use.

strip along the existing building’s north facade, and (d) an existing
concrete sidewalk along the north edge of that landscape strip)] and
(2) Proposed minor site improvements relating to the building addition,
including the following:
(a) A driveway connection between the proposed overhead garage
doors on the addition’s west facade and the existing parking lot’s
north-south driveway aisle to the west;
(b) A northward shift of the existing driveway located to the north of
the existing building, a shift to be accomplished by
(i) eliminating parking-stall striping from 15 of the
existing parking stalls along the north edge of the
parking lot to the north of the existing building and
(ii) replacing with concrete pavement the portion of the
existing landscape planter island that currently stems to
the south off the west end of the main portion of the
existing landscape planter island along the north edge
of the north parking lot;
(c) An addition of a new landscape planter strip along the proposed
addition’s north facade (with an extension thereof to the west that
will extend approximately 16 feet west of the proposed building
addition’s west facade)];
(d) Installation of a new landscape planter strip along roughly the
north two-fifths of the proposed addition’s east facade; and
(e) Installation of a new concrete sidewalk along roughly the south
three-fifths of the proposed addition’s east facade.
Attachment 2 also illustrates a layout of a City water main that is proposed to replace a
segment of the City’s existing 10-inch diameter water main which currently lies beneath part of
the existing north parking lot along the very north edge of the proposed building addition’s
footprint.
For a more close-up and detailed depiction of the north end of the subject parcel with
extensive labeling, see Attachment 3, which has been created from Sheet A1.1 (Topography
Map, Demolition Site Plan, & Proposed Project Site Plan) prepared by Cornerstone (on which I
had my legal assistant add some color shading and labeling). The left half of Exhibit 3 depicts

the existing conditions of the north end of the subject parcel [with indicators of existing
improvements therein that are to be removed or modified, including an area of concrete
pavement to be eliminated (most of that area to be permanently eliminated but a segment of it is
to be temporarily eliminated for a short time period during project construction as explained in
footnote 3 on page 6, below, in conjunction with the installation of the replacement water main)].
The right half of Attachment 3 depicts the north end of the subject parcel as proposed with the
building expansion and associated project site improvements.
Explanation of the Existence of a Narrow Linear Wetland
in the West Margin of the Valley Freeway Right-of-Way
That Abuts the Subject Parcel’s East Boundary
The environmental consulting firm Wetland Resources, Inc. (“WRI”) has performed a
critical areas study and determination concerning the subject parcel and its surroundings and has
prepared an updated Critical Areas Determination Report dated May 15, 2017 for the U.S. Bank
Expansion project.2 A PDF of that report accompanies this letter as Attachment 4. At the end of
section 1.0 of the Attachment 4 report, WRI summarizes the report’s key findings as follows:
There are no wetlands on the subject parcel. There is also no stream or lake on,
abutting, or adjacent to the subject parcel. Similarly, there is no critical wildlife
habitat on, abutting, or adjacent to the subject parcel.
There is one Category III wetland present off-site, to the east of the subject parcel.
That wetland is identified as “Wetland A” on the Determination Map in Appendix
2 Note that I provided a copy of an original version of WRI’s Critical Areas Determination Report dated April
13, 2017 to Associate Planner Angelea Weihs during a meeting that project architect Rick Utt, AIA of
Cornerstone Architectural Group and I had with her concerning the proposed project. During that meeting, I
provided her a copy of the original version of the report in support of a request I orally made to her during that
meeting that the wetland assessment report requirement pursuant to RMC 4-3-050F.7.c be waived. (During
that meeting, I went over carefully with her the portion of that original report dealing with RMC 4-3-050F.7.c
in the circumstances of the subject proposal.) Following her discussion of that waiver request with Current
Planning Manager Vanessa Dolbee, Ms. Weihs advised me by phone that submittal of the wetland assessment
report would not be required as part of Strada’s application for the proposed U.S. Bank Expansion project, but
to my surprise she nevertheless contended that the building would have to be located outside of the ordinarily
required buffer (a 75-foot buffer according to WRI’s original report) for the class of the subject off-site
wetland plus a 15-foot building setback beyond the buffer.
Subsequently, after reviewing RMC 4-3-050B.1.g, I explained to Ms. Weihs by phone why, under the
circumstances of the proposed project site, wetland critical areas regulations are inapplicable to the proposed
project. After she discussed my comments with Planning Director Jennifer Henning, Ms. Weihs phoned me
back and advised me that Ms. Henning told her that I should prepare and submit a letter addressed to you
requesting a determination. Before preparing this letter, I asked WRI to prepare an updated report, adding a
section (section 5.0) to provide documentation specifically addressing RMC 4-3-050B.1.g. The updated WRI
report accompanying this letter as Attachment 4 was thus prepared.

C. Wetland A received 5 points for habitat on the Wetland Rating Form for
Western Washington (Hruby 2014).
The locations of the wetland flags that WRI placed along Wetland A’s west edge as part
of WRI’s field work were field surveyed by a land surveying crew of Bush, Roed, & Hitchings,
Inc. (“BRH,” a land surveying and civil engineering firm) and plotted by BRH at its office in a
CAD file of a survey sheet in proximity to Lots 2 and 3. Based on the plotted flag locations,
BRH depicted with a dashed line in the CAD file the interpolated west boundary of Wetland A in
relation to the east boundary of Lot 3 and in relation to the southern part of the east boundary of
Lot 2 (the abutting lot to the north of Lot 3).
Upon completion of the CAD file, BRH provided it for use by both WRI and Cornerstone
Architectural Group. WRI used that CAD file depiction of the surveyed wetland edge in WRI’s
creation of the Determination Map (a map depicting Wetland A included as Appendix C to
Attachment 4). Likewise, Cornerstone has used that CAD file depiction of the wetland edge on
Cornerstone Sheets A1.0 and A1.1 (see, again, Attachment 2 and Attachment 3).
Explanation of the Existing Concrete-Paved Parking Lot
Driveway That Will Remain between the Proposed Addition and
Wetland A Following Completion of the Expansion Project
Attached as Appendix D to the Attachment 4 WRI report is a May 15, 2017 technical
memorandum from BRH civil engineer Zachary J. Evans, PE. Please review that memorandum,
which carefully summarizes (1) the existing stormwater detention and conveyance system that
serves Lots 1, 2, and 3 and that discharges stormwater runoff to a City of Renton storm drain
pipe within East Valley Road, (2) the lack of discharge of stormwater runoff from Lot 3 to the
off-site wetland to the east, and (3) the proposed retention of an extensive area of concrete
parking lot improvements between the proposed building addition and the off-site wetland to the
east.
Attachment 3 makes clear that the shortest distance between the proposed building
addition and Wetland A lies between the proposed addition’s northeast corner along a line that
(1) is drawn from that corner of the addition perpendicular east-northeast to the SR 167 (Valley
Freeway) west right-of-way line and (2) extends across that right-of-way line to the wetland’s
west boundary. Cornerstone has used its CAD system to determine that the total distance along
that line lying between the northeast corner of the proposed building addition and the wetland is
87.5 feet. As can be seen along that line (which is the yellow-highlighted line on Attachment 3),
Cornerstone’s Sheet A1.1 breaks down that total distance along that line into the following four
segments:
(a) A 6’-1” segment between (i) the building addition’s northeast corner and
(ii) the proposed new concrete curb to be installed along the east edge of
the new planting strip to be created along the north half of the proposed
addition’s west facade (this 6’-1” segment of the overall distance currently

crosses some of the existing concrete parking lot driveway that lies along
the existing building’s north end);
(b) A 61’-4” segment between (i) that above-noted proposed new curb and (ii)
the existing curb along the east edge of the existing concrete-paved
parking lot driveway near the subject parcel’s east edge (this 61’-4”
segment of the overall distance crosses part of the existing concrete
parking lot driveway that is to remain3);
(c) A 10’-0” segment across the existing landscape planting strip located
between (i) that existing curb along the east edge of the existing concrete-
paved parking lot driveway and (ii) the subject parcel’s east boundary line
[a boundary line that is also the Valley Freeway (SR 167) west right-of-
way line]; and
(d) A 10’-1” segment from the subject parcel’s east boundary to the wetland’s
west boundary.
Excerpts from RMC 4-30-050 That
Relate to the Subject Requests
Subsections B, D, and F of RMC 4-30-050 (CRITICAL AREAS REGULATIONS) state
in part as follows:
*
*
*
B. APPLICABILITY:
1. Lands to Which These Regulations Apply and Non-Regulated Lands: The
following critical areas are regulated by this Section. Multiple development
standards may apply to a site feature based upon overlapping critical area(s)
and/or critical area classifications:
3 Note that near the building addition’s northeast corner, a new segment of 10-inch-diameter water main is
proposed to be installed as a replacement to an existing segment of the City’s water main that would otherwise
lie beneath the proposed addition. A segment of the existing concrete pavement along the route of the
replacement water main segment is to be removed to enable the installation of the new replacement water main
segment. Immediately following the new main segment’s installation, a replacement concrete slab will be
poured in the area of the pavement slab removed for the replacement water main installation. (On Attachment
2, the location of the replacement water main segment and of the maximum expected extent of the area of
concrete pavement removal and replacement associated with the water main segment installation has been
shaded in blue.)

g. Sites Separated from Critical Areas, Nonregulated: As determined by the
Administrator, these regulations may not apply to development proposed on
sites that are separated from critical areas by pre-existing, intervening, and
lawfully created structures, roads, or other substantial existing
improvements. For the purposes of this Section, the intervening lots/parcels,
roads, or other substantial improvements shall be found to:
i. Separate the subject upland property from the critical area due to their
height or width; and
ii. Substantially prevent or impair delivery of most functions from the
subject upland property to the critical area. Such determination and
evidence shall be included in the application file. Public notification shall
be given as follows:
(a) For applications that are not subject to notices of application
pursuant to Chapter 4-8 RMC, notice of the buffer determination shall
be given by posting the site and notifying parties of record, if any, in
accordance with Chapter 4-8 RMC.
(b) For applications that are subject to notices of application, the buffer
determination or request for determination shall be included with
notice of application. Upon determination, notification of parties of
record, if any, shall be made.

site shall be indicated on the plans submitted based upon an inventory provided
by a qualified specialist.
*
*
*
b. Habitat Conservation Areas: Based upon subsection G6 of this Section,
Habitat Conservation Areas, the City shall require a habitat/wildlife
assessment for activities that are located within or abutting a critical habitat,
defined in RMC 4-11-030, or that are adjacent to a critical habitat, and have
the potential to significantly impact a critical habitat. The assessment shall
determine the extent, function and value of the critical habitat and potential
for impacts and mitigation consistent with report requirements in RMC 4-8-
120D.
*
*
*
e. Wetlands:
i. Wetland Categorization: The applicant shall be required to conduct a
study to determine the categorization of the wetland if the subject property
or project area is within two hundred feet (200') of a wetland even if the
wetland is not located on the subject property but it is determined that
alterations of the subject property are likely to impact the wetland in
question or its buffer.4 If there is a potential Category I or II wetland
within three hundred feet (300') of a proposal, the City may require an
applicant to conduct a study even if the wetland is not located on the
subject property but it is determined that alterations of the subject property
are likely to impact the wetland in question or its buffer.
ii. Wetland Delineation: A wetland delineation using the methods
identified in the approved federal delineation manual and applicable
regional supplement, as required by WAC 173-22-035, is required for any
portion of a wetland on the subject property that will be impacted by the
permitted activities.
4 Note that in the Attachment 4 Critical Areas Report, WRI went ahead and determined the categorization of
Wetland A (determining it to be a Category III wetland) despite the fact that (for the reasons explained in that
report and in the BRH memorandum attached to that report as Appendix D) the proposed alterations of the
subject property will not impact the wetland in question or its buffer.

The Definition of “Critical Habitat” in
RMC 4-11-030 DEFINITIONS C
In RMC 4-11-030 DEFINITIONS C, the definition of “Critical Habitat” (a term that,
therein, is synonymous with “Critical Wildlife Habitat”) is set forth as follows:
CRITICAL HABITAT or CRITICAL WILDLIFE HABITAT: Habitat areas
associated with threatened, endangered, sensitive, monitored, or priority species
City of Renton Department of Community and Economic Development
Attn: Chip Vincent, Administrator
May 16, 2017
Page 11
of plants or wildlife and which, if altered, could reduce the likelihood that the
species would maintain and reproduce over the long term. See also RMC 4-3-
050K.
Why Strada’s Request for Waiver of a Habitat Assessment
Report Pursuant to RMC 4-3-050F.7.a Should be Granted
The fourth main paragraph on page 7 of WRI’s Attachment 4 Critical Areas Report states
in its entirety as follows:
As noted above in section Error! Reference source not found. of this report,
critical wildlife habitat is not present on, abutting, or adjacent to the proposed
project site. In view of the introductory clause of above-quoted subsection F.7 of
RMC 4-3-050, and considering the field documentation herein provided that
critical habitat is not present, a waiver of the habitat assessment requirement is
appropriate. (Consideration of subsection F.7.a is only needed when critical
habitat is present, which is not the case here.)
Because of (1) WRI’s field documentation that no critical wildlife habitat is present on, abutting,
or adjacent to the proposed project site and (2) above-quoted RMC 4-3-050F.7.a’s predicate for
the requirement of a habitat assessment is that “activities … are located within or abutting a
critical habitat, defined in RMC 4-11-030, or … are adjacent to a critical habitat, and have the
potential to significantly impact a critical habitat” (emphasis added), the waiver should be
granted.
Why Strada’s Request for Waiver of a Wetland Assessment
Pursuant to RMC 4-3-050F.7.c Should Be Granted
Strada’s request for waiver of a wetland assessment should be granted for the following
reasons:
(1) The Attachment 4 WRI Critical Areas Determination Report provides
field documentation of the location of the subject off-site wetland
(Wetland A) in relation to the subject parcel (see the Determination Map,
which is Appendix C to the WRI report); and
(2) As discussed on pages 5 to 6, above, Attachment 2 and Attachment 3
illustrate that, following completion of the construction project, an
existing concrete-paved parking lot that is 61’-4” wide (along the line of
the closest distance between the proposed building addition and the
wetland) will remain between (a) the proposed activity/project site area
and (b) the wetland (while on page 2 of the memorandum from BRH civil
engineer Zachary J. Evans, PE that is attached as Appendix D to the
City of Renton Department of Community and Economic Development
Attn: Chip Vincent, Administrator
May 16, 2017
Page 12
Attachment 4 WRI report states that “[t]he completed proposed project will
retain the substantial existing intervening 60-foot-wide area of parking lot
driveway aisle and vertical curbing between Wetland A and the closest point of
the proposed building addition”);
(3) Because (a) a road, building or other barrier are alternative barriers for
purposes of above-quoted RMC 4-3-050F.7.c, (b) the subject concrete-
paved parking lot with its poured-in-place vertical curb has a surface
construction comparable to that of a road, and (c) the 60-foot-width of the
existing concrete-paved parking lot between Wetland A and the proposed
building addition to remain is much wider than most roads in Renton, the
portion of the existing subject parking lot to be retained between Wetland
A and the proposed building addition constitute an “other barrier” for
purposes of above-quoted RMC 4-3-050F.7.c; and
(4) Under these circumstances the text of RMC 4-3-050F.7.c explicitly
mandates waiver of the wetland assessment report requirement.
Why Strada’s Request for a Determination Pursuant to RMC 4-3-050B.1.g
that the Wetland Critical Areas Regulations of RMC 4-3-050 Do Not Apply
to the Proposed Addition’s Activity/Project Site Should Be Granted
Under the heading No Project Effects on the Hydrology of Off-site Wetland, the final
section of the memorandum from BRH civil engineer Zachary J. Evans, PE (which is attached as
Appendix D to the Attachment 4 WRI report) states in part as follows:
The proposed building expansion project will not change the subject parcel’s
drainage pattern in any way. The completed proposed project will retain the
substantial existing intervening 60-foot-wide area of parking lot driveway aisle
and vertical curbing between Wetland A and the closest point of the proposed
building addition (the building addition’s northeast corner)…. Because of the
combined width of the retained pavement and vertical curbing and the 6” height
of the retained vertical curbing, those substantial existing intervening
improvements will separate the subject building addition project site property
from the Wetland A critical area.
*
*
*
The U.S. Bank Expansion project involves retention of both (1) the substantial
width of the intervening existing concrete pavement and the vertical curbing
between the proposed building expansion and Wetland A (which together serve as
City of Renton Department of Community and Economic Development
Attn: Chip Vincent, Administrator
May 16, 2017
Page 13
a barrier separating the subject expansion project site from the wetland critical
area due to the retained overall width of the pavement and vertical curbing and
due to the retained vertical curbing’s 6-inch height) and (2) the associated
substantial intervening stormwater detention and conveyance system that has
directed all stormwater runoff from Lot 3 (with the exception of runoff from Lot
3’s west parking lot, which drains into grass-lined infiltration swale segments
along parts of Lot 3’s west edge, and with the possible exception of runoff, if any,
from the east edge of the existing landscape planting strip along the parcel’s east
10 feet) to the west into the East Valley Road drainage system (away from the
Valley Freeway right-of-way and Wetland A). Those substantial existing
intervening project features, which have been in existence since the original
building’s completion in 1991, will continue to serve as a barrier (1) separating
from Wetland A the subject expansion project site upland area and (2) preventing
that upland area (as well as the area of the intervening parking lot
improvements) from delivering any storm water runoff to Wetland A.
(Emphasis added.)
After referencing civil engineer Evans’ memorandum, Section 5.0 of the Attachment 4
WRI report states in part as follows:
The proposed retained substantial intervening improvements will continue to
prevent any stormwater runoff from both (1) the proposed building addition’s
project site area (the area that is referred to as the “subject upland area” in above-
quoted RMC 4-3-050B.1.g.ii) and (2) the area of those retained intervening
improvements from draining to the east into Wetland A. Therefore, there is no
hydrologic connection between the off-site wetland area and the subject
upland property area where development activity is proposed. Thus, the
subject upland area is currently prevented, and will continue to be prevented,
from providing protection or enhancement functions to the water quality or
flood protection functions of Wetland A.
Additionally, no screening, vegetative structure, or other habitat elements are
present within the existing paved area to remain, and no substantial alteration of
this condition is proposed. Therefore, protection or enhancement, by the subject
upland property area, of habitat functions in the adjacent off-site wetland is
also currently prevented and will continue to be prevented.
In view of the above, delivery of all functions from the subject upland
building addition project site area to Wetland A will be prevented by the
intervening improvements proposed to be retained between the proposed
building expansion and Wetland A. Under these circumstances, the wetland

Strada da Valle LLC Critical Areas Determination Report
WRI #17029 – May 2017 U.S. Bank Expansion 1
1.0 INTRODUCTION
The subject U.S. Bank Expansion project is proposed at the north end of the existing office
building that is situated on a 3.08-acre parcel of land (Assessor’s parcel #3023059103) located at
2500 East Valley Road in the City of Renton, Washington, within a portion of Section 30,
Township 23N, Range 05E, W.M. Access between the subject parcel and East Valley Road is
provided by two existing driveways on the west side of the parcel. The subject parcel is located
within the Duwamish-Green Watershed, Water Resources Inventory Area (WRIA) 9.
Surrounding land uses consist primarily of commercial and industrial development. The east
boundary of the subject parcel abuts the west boundary of State Route 167 (Valley Freeway)
right-of-way and is located approximately 40 feet west of the westernmost edge of the paved
Valley Freeway improvements. The subject parcel is located approximately 1.3 miles east of the
Green River. The subject parcel is entirely developed, primarily with an existing office building
and associated concrete-paved impervious surfaces (driveways, parking stalls, and walkways).
Topography of the subject parcel is relatively flat.
Wetland Resources, Inc. (WRI) conducted a site investigation on February 7, 2017 to locate
wetlands, streams, or critical wildlife habitat that may exist on or adjacent to the subject parcel.
Aerial view of the subject parcel. Figure 1:

WRI #17029 – May 2017 U.S. Bank Expansion 2
There are no wetlands on the subject parcel. There is also no stream or lake on, abutting, or
adjacent to the subject parcel. Similarly, there is no critical wildlife habitat on, abutting, or
adjacent to the subject parcel.
There is one Category III wetland present off-site, to the east of the subject parcel. That wetland
is identified as “Wetland A” on the Determination Map in Appendix C. Wetland A received 5
points for habitat on the Wetland Rating Form for Western Washington (Hruby 2014).
The applicant, Strada da Valle LLC, is proposing to construct a two-bay truck parking garage as
an extension to the existing on-site building. The garage will be built against part of the north
face of the existing building on the subject parcel.
1.1 CRITICAL AREAS CLASSIFICATIONS
Cowardin System Classifications
According to the Cowardin System, as described in Classification of Wetlands and Deepwater Habitats
of the United States (Cowardin 1979), the classification of the off-site wetland critical area is as
follows:
Wetland A: Palustrine, Forested, Seasonally Flooded (PFOC).
City of Renton Classifications
Pursuant to RMC 4-3-050F.2.e, the off-site critical area is classified as a Category III wetland
under the Washington State Wetland Rating System for Western Washington: 2014 Update (Hruby 2014).
Using this system, Wetland A received a total score of 19 points, with a habitat score of 5 (see
Appendix B).

3.0 CRITICAL AREAS DETERMINATION REPORT
3.1 PUBLICLY AVAILABLE DATA AND DATA FROM THE PROPOSAL’S GEOTECHNICAL REPORT
Prior to conducting the site investigation, public resource information was reviewed to gather
background information on the subject parcel and the surrounding area in regards to wetlands,
streams, and other critical areas. These sources included the following:
USDA/NRCS Web Soil Survey
The Web Soil Survey indicates Tukwila Muck present at the subject parcel. Tukwila Muck is
mapped as hydric (i.e. wetland) soil per the USDA/NRCS. A more detailed soil map unit
description is provided in section, 3.2.2 Soils Criteria and Mapped Description, below.
StreamNet Mapper
This public resource maps Panther Creek along the east side of the Valley Freeway. A segment
of Panther Creek is located approximately 0.2 miles north of the subject parcel as well.
WDFW SalmonScape Interactive Mapping System
StreamNet Mapper confirms the presence of Panther Creek identified by StreamNet.
USFWS National Wetlands Inventory (NWI)
Wetland A is shown immediately off-site to the east of the subject parcel. No wetlands are
depicted on the subject parcel.
WDFW Priority Habitat and Species (PHS) Interactive Map
According to the WDFW Priority Habitat and Species (PHS) online mapping application, no
priority species or habitats are present on the subject parcel. This resource identifies Panther
Creek as described above. A large wetland system is also mapped approximately 230 feet east of
the subject parcel, east of the Valley Freeway improvements.
City of Renton Public GIS Streams and Wetlands Maps
The Renton Map public GIS mapping system indicates a wetland within the west margin of the SR
167 freeway along the east edge of the subject parcel. Additionally, Panther Creek is identified
along the east edge of the freeway right-of-way.
On-Site Soils Data from the Geotechnical Report Prepared for the Subject Proposal
A Geotechnical Report for the subject proposed U.S. Bank Expansion Project dated April 17,
2017 was prepared by Terra Associates, Inc. following a test boring for soils data in the location
of the proposed building expansion performed on April 1, 2017 under the auspices of Terra
Associates. The first paragraph of Section 3.2 (Soils) of the Geotechnical Report states as
following:
The soils observed in the test boring consist of approximately 9.5 feet of fill overlying native
lacustrine and alluvial deposits. The fill soils generally consist of loose to medium dense, moist,
Strada da Valle LLC Critical Areas Determination Report
WRI #17029 – May 2017 U.S. Bank Expansion 4
silty fine sand to fine sandy silt with varying amounts of gravel and scattered brick fragments, and
stiff, moist, clayey silt with scattered angular siltstone fragments.
3.2 FIELD DETERMINATION METHODOLOGY
Wetland boundaries were determined using the routine 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 following criteria must be met in order to make a positive wetland determination:
3.2.1 Hydrophytic Vegetation Criteria
The Corps Manual and 2010 Regional Supplement define hydrophytic vegetation as “the
assemblage of macrophytes that occurs in areas where inundation or soil saturation is either
permanent or of sufficient frequency and duration to influence plant occurrence.” Field
indicators are used to determine whether the hydrophytic vegetation criteria have been
met. Examples of these indicators include, but are not limited to, the rapid test for hydrophytic
vegetation, a dominance test result of greater than 50%, and/or a prevalence index score less
than or equal to 3.0.
3.2.2 Soils Criteria and Mapped Description
The 2010 Regional Supplement (per the National Technical Committee for Hydric Soils) defines
hydric soils as soils “that formed under conditions of saturation, flooding, or ponding long
enough during the growing season to develop anaerobic conditions in the upper part.” Field
indicators are used to determine whether a given soil meets the definition for hydric
soils. Indicators are numerous and include, but are not limited to, presence of a histosol or histic
epipedon, a sandy gleyed matrix, depleted matrix, and redoximorphic depressions.
According to the NRCS Web Soil Survey, the soil map unit Tukwila Muck is predicted to occur
on the subject property. Tukwila Muck is identified as a hydric soil. This very poorly drained
soil is likely to be found in areas that experience frequent ponding and has very high available
water storage in its profile. Available water capacity is described as moderately high to high.
While Tukwila Muck may exist at the site of Wetland A, it is absent from the proposed project
area. As described in the excerpt from the Geotechnical Report referenced in section 3.1 above,
on-site soil in the location of the proposed building expansion is comprised of fill material, which
is not a hydric soil.
Strada da Valle LLC Critical Areas Determination Report
WRI #17029 – May 2017 U.S. Bank Expansion 5
3.2.3 Hydrology Criteria
Wetland hydrology encompasses all hydrologic characteristics of areas that are periodically
inundated or have soils saturated to the surface for a sufficient duration during the growing
season. Areas with evident characteristics of wetland hydrology are those where the presence of
water has an overriding influence on the characteristics of vegetation and soils due to anaerobic
and chemically reducing conditions, respectively. The strongest indicators include the presence
of surface water, a high water table, and/or soil saturation within at least 12 inches of the soil
surface.
3.2.4 Wetland Demarcation
Wetland delineation flags were installed along the western edge of the portion of Wetland A that
lies to the east of the subject parcel (see Appendix C) to demarcate its extents. In the case of off-
site wetland areas, such as Wetland A, the edge(s) adjacent to an investigated parcel are
demarcated with flagging. The nearest flag to the subject parcel boundary was placed
approximately 6 feet to the east of the boundary.
Bush, Roed & Hitchings, Inc. (professional civil engineers and land surveyors) had a field survey
crew field locate wetland flags installed to the east of the subject parcel, and then had its office
staff plot the locations of the flags in relation to the subject parcel’s boundary. Subsequently,
they prepared and provided a CAD file with the wetland flag locations plotted, and an
interpolated dashed line indicating the western extent of flagged Wetland A.
3.3 WETLAND BOUNDARY DETERMINATION FINDINGS
Based on the results of the site investigation, one wetland (Wetland A) was identified off-site, to
the east of the subject parcel. No wetlands are located on the subject parcel. Wetland A is linear
and lies within the west margin of the Valley Freeway right-of-way (see Appendix C). We
classified this wetland pursuant to RMC 4-3-050F.2.e.
3.3.1 Off-site Wetland A
Wetland A is a depressional wetland located off-site to the east of the subject parcel within the
Valley Freeway’s west margin. The wetland extends north and south of the subject parcel within
the Valley Freeway’s west margin.
Dominant vegetation within the wetland includes: hardhack (Spiraea douglasii; FACW), reed
canarygrass (Phalaris arundinacea; FACW), and duckweed (Lemna minor; OBL). The majority of the
dominant species rate “facultative” or wetter, indicating that a hydrophytic vegetative
community is present.
Typical soils in Wetland A extending from 0 to 16 inches below the surface have a Munsell color
of black (10YR 2/1), with prominent strong brown (7.5YR 4/6) redoximorphic features, and a
silty loam texture. Soils were saturated at the time of our February 2017 site investigation. This
soil profile meets the Redox Dark Surface (F6) hydric soil indicator.
Strada da Valle LLC Critical Areas Determination Report
WRI #17029 – May 2017 U.S. Bank Expansion 6
Precipitation, surface water runoff, and culverts draining areas east of the freeway provide
hydrology to the wetland. Ponding up to 10 inches deep and saturated soils were observed in
Wetland A during the February 7, 2017 site visit, thus meeting the Surface Water (A1), High
Water Table (A2), and Saturation (A3) primary indicators of hydrology.
Given the hydrophytic community, hydric soils, and presence of hydrology, the area mapped as
off-site Wetland A meets the criteria for a wetland.
3.3.2 Non-wetland Areas
In non-wetland areas adjacent to the western edge of the off-site wetland (Wetland A), dominant
vegetation includes: western red cedar (Thuja plicata; FAC), red osier dogwood (Cornus alba;
FACW), Sitka willow (Salix sitchensis; FACW), trailing blackberry (Rubus ursinus; FACU), and
English laurel (Prunus laurocerasus).
Typical soils from 0 to 18 inches below the soil surface in the area adjacent to the wetland have a
Munsell color of dark brown (10YR 3/3), with a loamy sand texture. Soil was slightly moist at the
time of our February 2017 site investigation. This soil profile does not meet any hydric soil
indicators.
No hydrological indicators were observed in the non-wetland areas adjacent to Wetland A.
Although a hydrophytic vegetation community is present, given the lack of hydrology and hydric
soils, the areas mapped as non-wetland adjacent to Wetland A do not meet the criteria for
wetlands.
3.3.3 Wildlife
The narrow off-site wetland critical area is somewhat forested, providing limited habitat for
urban wildlife. The immediately adjacent freeway and surrounding commercial and industrial
development (including the subject parcel) isolate forested Wetland A. Nevertheless, the wetland
critical area and the vegetated portion of its buffer, which together lie within the west margin of
the freeway right-of-way, provide minimal habitat elements in the form of resources such as food,
water, thermal cover, and hiding cover in close proximity. Given the small size of Wetland A, as
well as the isolated nature of this wetland created by nearby development, this off-site wetland
provides relatively low-quality wildlife habitat. The habitat associated within Wetland A does
not meet the definition of Critical Habitat as set forth in RMC 4-11-030.
Mammalian species expected to occur within the wetland critical area and its vegetated buffer
within the west margin of the Valley Freeway right-of-way include gray squirrel (Sciurus spp.),
Virginia opossum (Didelphis virginiana), skunk (Mephitis spp.), and raccoon (Procyon lotor). Given the
habitat available, it is expected that the following avian species may use the area: American Crow
(Corvus brachyrhynchos), American Robin (Turdus migratorius), Song Sparrow (Melospiza melodia),
Black-capped Chickadee (Poecile atricapillus), Golden-crowned Kinglet (Regulus satrapa), Ruby-
crowned Kinglet (Regulus calendula), and Dark-eyed Junco (Junco hyemalis). Song Sparrow
(Melospiza melodia) activity was observed within the wetland during the site visit. No threatened or
endangered species are known or expected to be associated with the subject parcel. In sum, no
critical wildlife habitat area is present on, abutting, or adjacent to the subject parcel.

WRI #17029 – May 2017 U.S. Bank Expansion 7
4.0 PLANNED REQUESTS FOR WAIVERS OF CRITICAL AREAS ASSESSMENTS
No wetlands, streams, lakes, or critical wildlife habitat are present on the subject parcel. One
wetland (Wetland A) is adjacent to the eastern boundary of the subject parcel, but no streams,
lakes, or critical wildlife habitat abut or are adjacent to the subject parcel.
We understand that, pursuant to subsection F.7 (Waiver of Submittal Requirements) of Renton
Municipal Code (RMC) Section 4-3-050 (CRITICAL AREAS REGULATIONS), Strada da
Valle LLC intends to request from the City a waiver of both (1) the habitat assessment report
(aka a habitat data form) submittal requirement and (2) the wetland assessment report submittal
requirement.
Concerning the topics of criteria for waiver of habitat assessment report and wetland assessment
report submittal requirements, the relevant portions of Subsection F.7, presented in italics below,
read as follows (some of the text outside of the subsection titles has been underlined and
boldfaced):
7. Waiver of Submittal Requirements: An applicant may request that the
Administrator waive the report requirement pursuant to subsection D of this Section, where it
has been determined through field documentation that critical areas
are not present or as specified below:
a. Habitat Assessment: In cases where a proposal is not likely to significantly
impact the critical habitat and there is sufficient information to determine the effects of a
proposal, an applicant may request that this report be waived by the Administrator.
*
*
*
c. Wetland Assessment: The wetland assessment shall be waived by the
Administrator when the applicant provides satisfactory evidence that a
road, building or other barrier exists between the wetland and the
proposed activity, when the buffer area, determined with a wetland categorization,
needed or required will not intrude on the applicant’s lot, or when applicable data and
analysis appropriate to the project proposed exists and an additional report is not necessary.
As noted above in section 3.3.3 of this report, critical wildlife habitat is not present on, abutting,
or adjacent to the proposed project site. In view of the introductory clause of above-quoted
subsection F.7 of RMC 4-3-050, and considering the field documentation herein provided that
critical habitat is not present, a waiver of the habitat assessment requirement is appropriate.
(Consideration of subsection F.7.a is only needed when critical habitat is present, which is not the
case here.)
Concerning a request for a waiver of the wetland assessment submittal requirement, above-
quoted subsection F.7.c of RMC 4-3-050 sets forth three alternative criteria, each of which
begins with the word “when.” (Note that the use of the word “or” after the second of the three
criteria makes each of the criteria independent.) The satisfaction of any one of those three
criteria qualifies an applicant for a wetland assessment submittal requirement waiver.
Strada da Valle LLC Critical Areas Determination Report
WRI #17029 – May 2017 U.S. Bank Expansion 8
The first of those alternative three criteria is satisfied under the circumstances of the proposed
project site conditions and the proposed building addition. Concerning the existence of a barrier
between Wetland A and the proposed U.S. Bank Expansion building addition project, the civil
engineer for the U.S. Bank Expansion project, Zachary J. Evans, PE of Bush, Roed, & Hitchings,
Inc. (Professional Land Surveyors and Civil Engineers) prepared a memorandum dated May 10,
2017 in which he explains in detail the existing physical circumstances of the subject parcel. This
explanation includes subject parcel’s existing improvements and drainage system (and drainage
pattern away from Wetland A) that act as a barrier, and the planned retention of existing
improvements between the site of the proposed building addition that will continue to act as such
a barrier (see Appendix D).
Since, as explained in detail in Mr. Evans’ memorandum, the width of the impervious parking lot
driveway and the 6-inch high vertical curb that currently exist between the upland project site
(location of proposed activity) and Wetland A, together with the subject parcel’s existing
stormwater detention and conveyance system (features that are shown on EXHIBITS 1, 2, and 3
within Appendix D), are all to be retained in place, they will act as a barrier separating Wetland
A from the upland project site.
The various components of this barrier described in Mr. Evans’ memorandum will act together
to direct all of the subject parcel’s stormwater runoff away from the Valley Freeway right-of-way
and Wetland A, thus preventing the upland project area from delivering any storm water runoff
to Wetland A
Also, because of the extent of the existing parking lot and driveway pavement and vertical
curbing between the upland proposed building addition project site and the offsite wetland, the
paved parking lot and driveway to be retained are at least as substantial a barrier as a road for
purposes of RMC 4-3-050F.7.c.
For the above reasons, the paved parking lot and driveway constitute an “other barrier” for
purposes of RMC 4-3-050F.7.c, making a request for, and grant of, a waiver of the wetland
assessment submittal requirement consistent with RMC 4-3-050F.7.c.
5.0 PLANNED REQUEST FOR A DETERMINATION OF NON-REGULATION
We also understand that, pursuant to subsection g (Sites Separated from Critical Areas,
Nonregulated), below, of RMC 4-3-050B.1 (Lands to Which These Regulations Apply and Non-
regulated Lands), Strada da Valle LLC plans to submit a request to the Administrator of the
Renton Department of Community and Economic Development for a determination that the
proposed project site is a non-regulated land for purposes of the Renton wetlands critical areas
regulations because of the pre-existing, intervening, and lawfully created parking lot and
stormwater detention and conveyance system improvements that were installed before the City’s
August 20, 1991 issuance of a certificate of approval for the existing building on the subject
parcel. Excerpts from RMC 4-3-050B.1 are set forth below in italics (our comments concerning
those excerpts are set forth below in non-italicized type):
RMC 4-3-050B.1 (Lands to Which These Regulations Apply and Non-regulated Lands):
Strada da Valle LLC Critical Areas Determination Report
WRI #17029 – May 2017 U.S. Bank Expansion 9
g. Sites Separated from Critical Areas, Nonregulated: As determined by the
Administrator, these regulations may not apply to development proposed on sites that are
separated from critical areas by pre-existing, intervening, and lawfully created structures,
roads, or other substantial existing improvements. For the purposes of this Section, the
intervening lots/parcels, roads, or other substantial improvements shall be found to:
i. Separate the subject upland property from the critical area due to their height or
width; and
As explained in the memorandum from project civil engineer Zachary Evans, PE (see Appendix
D), the extent of the proposed retained width of the existing impervious parking lot driveway
(which is a 60-foot-total width of concrete between Wetland A and the closest point of the
proposed building addition) and the 6-inch high vertical curb will serve as a barrier separating
Wetland A from the project site on the subject upland property.
ii. Substantially prevent or impair delivery of most functions from the subject upland
property to the critical area. Such determination and evidence shall be included in the
application file. Public notification shall be given as follows:
In general, the primary functions upland areas can potentially provide to an adjacent wetland are
protection and enhancement of the wetland’s functions. The three categories of functions
provided by wetlands are water quality, hydrology (flood protection), and habitat.
As explained in project civil engineer Zachary Evans’ memorandum (see Appendix D), the
existing east parking lot and driveway improvements already prevent delivery of runoff from any
portion of Lot 3 into Wetland A (with the possible exception of a small amount of runoff from the
eastern edge of the landscape strip that lies between the east parking lot and Wetland A). Mr.
Evans’ memorandum further explains that, with the proposed addition project, the runoff from
Lot 3 will continue to be prevented from draining to the wetland.
The proposed retained substantial intervening improvements will continue to prevent any
stormwater runoff from both (1) the proposed building addition’s project site area (the area that is
referred to as the “subject upland area” in above-quoted RMC 4-3-050B.1.g.ii) and (2) the area
of those retained intervening improvements from draining to the east into Wetland A.
Therefore, there is no hydrologic connection between the off-site wetland area and the subject
upland property area where development activity is proposed. Thus, the subject upland area is
currently prevented, and will continue to be prevented, from providing protection or
enhancement functions to the water quality or flood protection functions of Wetland A.
Additionally, no screening, vegetative structure, or other habitat elements are present within the
existing paved area to remain, and no substantial alteration of this condition is proposed.
Therefore, protection or enhancement, by the subject upland property area, of habitat functions
in the adjacent off-site wetland is also currently prevented and will continue to be prevented.
In view of the above, delivery of all functions from the subject upland building addition project
site area to Wetland A will be prevented by the intervening improvements proposed to be
retained between the proposed building expansion and Wetland A. Under these circumstances,
Strada da Valle LLC Critical Areas Determination Report
WRI #17029 – May 2017 U.S. Bank Expansion 10
the wetland critical areas regulations should not apply to the proposed U.S. Bank expansion
development proposal per subsection g of RMC 4-3-050B.1.
6.0 USE OF THIS REPORT

Wetland Rating System for Western WA: 2014 Update 3
Rating Form – Effective January 1, 2015
+*0&ODVVLILFDWLRQRI:HWODQGVLQ:HVWHUQ:DVKLQJWRQ
1. Are the water levels in the entire unit usually controlled by tides except during floods?
NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1
1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)?
NO – Saltwater Tidal Fringe (Estuarine) YES – Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the unit.
NO – go to 3 YES – The wetland class is Flats
If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
___The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
___At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
____The wetland is on a slope (slope can be very gradual),
____The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
____The water leaves the wetland without being impounded.
NO – go to 5 YES – The wetland class is Slope
NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and
shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft
deep).
5. Does the entire wetland unit meet all of the following criteria?
____The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that
stream or river,
____The overbank flooding occurs at least once every 2 years.
For questions 1-7, the criteria described must apply to the entire unit being rated.
If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you
probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in
questions 1-7 apply, and go to Question 8.
Go to First Page
Wetland name or number ______
Wetland Rating System for Western WA: 2014 Update 4
Rating Form – Effective January 1, 2015
NO – go to 6 YES – The wetland class is Riverine
NOTE: The Riverine unit can contain depressions that are filled with water when the river is not
flooding
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the
surface, at some time during the year? This means that any outlet, if present, is higher than the interior
of the wetland.
NO – go to 7 YES – The wetland class is Depressional
7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank
flooding? The unit does not pond surface water more than a few inches. The unit seems to be
maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural
outlet.
NO – go to 8 YES – The wetland class is Depressional
8. Your wetland unit seems to be difficult to classify and probably contains several different HGM
classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small
stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY
WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT
AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the
appropriate class to use for the rating system if you have several HGM classes present within the
wetland unit being scored.
NOTE: Use this table only if the class that is recommended in the second column represents 10% or
more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2
is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the
total area.

Wetland Rating System for Western WA: 2014 Update 15
Rating Form – Effective January 1, 2015

Priority habitats listed by WDFW (see complete descriptions of WDFW priority habitats, and the counties in which they can
be found, in: Washington Department of Fish and Wildlife. 2008. Priority Habitat and Species List. Olympia, Washington.
177 pp. http://wdfw.wa.gov/publications/00165/wdfw00165.pdf or access the list from here:
http://wdfw.wa.gov/conservation/phs/list/)
Count how many of the following priority habitats are within 330 ft (100 m) of the wetland unit: NOTE: This question is
independent of the land use between the wetland unit and the priority habitat.
Aspen Stands: Pure or mixed stands of aspen greater than 1 ac (0.4 ha).
Biodiversity Areas and Corridors: Areas of habitat that are relatively important to various species of native fish and
wildlife (full descriptions in WDFW PHS report ).
Herbaceous Balds: Variable size patches of grass and forbs on shallow soils over bedrock.
Old-growth/Mature forests: Old-growth west of Cascade crest – Stands of at least 2 tree species, forming a multi-
layered canopy with occasional small openings; with at least 8 trees/ac (20 trees/ha ) > 32 in (81 cm) dbh or > 200
years of age. Mature forests – Stands with average diameters exceeding 21 in (53 cm) dbh; crown cover may be less
than 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally less than that
found in old-growth; 80-200 years old west of the Cascade crest.
Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak
component is important (full descriptions in WDFW PHS report p. 158 – see web link above).
Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and
terrestrial ecosystems which mutually influence each other.
Westside Prairies: Herbaceous, non-forested plant communities that can either take the form of a dry prairie or a wet
prairie (full descriptions in WDFW PHS report p. 161 – see web link above).
Instream: The combination of physical, biological, and chemical processes and conditions that interact to provide
functional life history requirements for instream fish and wildlife resources.
Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and
Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report –
see web link on previous page).
Caves: A naturally occurring cavity, recess, void, or system of interconnected passages under the earth in soils, rock,
ice, or other geological formations and is large enough to contain a human.
Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation.
Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite,
and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs.
Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to
enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western
Washington and are > 6.5 ft (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft
(6 m) long.
Note: All vegetated wetlands are by definition a priority habitat but are not included in this list because they are addressed
elsewhere.

information shown on that exhibit is from the 2009 BRH field survey. In addition, that exhibit shows our
firm’s plot of the March 2017 field survey of the location of the west boundary of the off-site wetland that
Wetland Resources, Inc. flagged within the west margin of the SR 167 (Valley Freeway) right-of-way this
February along Lot 3’s east edge and along a portion of the east edge of Lot 2, a wetland that Wetland
Resources refers to as Wetland A. On this exhibit, I have now shown in blue the existing stormwater system
infrastructure, along with surface flow arrows in both Lots 2 and 3. In red, I have added the outline of the
proposed building expansion, along with a few dimensions relating to the wetlands.
Strada’s private stormwater system serves Lots 1, 2, and 3. The system contains a detention pond along
the southern edge of Lot 3, multiple detention pipes beneath the western parking lot of Lots 2 and 3, an
oil/water separator, and multiple catch basins and drainage conveyance pipes to capture and convey runoff
from the existing building and from the site’s east, north, and south parking lots. Runoff from the west
parking lots of Lots 2 and 3 drain into grass-lined infiltration swale segments along parts of the west edge
of those two lots. Aside from the west parking lot runoff that infiltrates within those swales, the runoff
from all the rest of the development’s hard surfaces, including the roofs, parking areas, and sidewalks, are
captured in the detention and conveyance system, a system that discharges to the public stormwater system
in East Valley Road near Lot 2’s north-to-south mid-point.
The west edge of the delineated Wetland A runs roughly parallel to the eastern boundary of Lot 3 and the
eastern boundary of the southern portion of Lot 2. A 6-inch-high poured-in-place concrete curb along the
eastern edge of Lot 3’s eastern parking lot prevents any stormwater runoff from that eastern parking lot
from entering the wetland. Two catch basins along that curb’s gutter direct this stormwater into the private
stormwater conveyance and detention system described above. The eastern 10’ of Lot 3, between the
property line and the curb line, consists of a mounded landscape planter strip with trees and shrubs. The
larger portion of the runoff from this landscape planter strip drains west into Lot 3’s eastern parking lot,
while a small portion of the runoff from the strip may drain east toward the wetland. No other portions of
Lot 3 drain toward Wetland A.
No Project Effects on the Hydrology of Off-site Wetland
The proposed building expansion project will not change the subject parcel’s drainage pattern in any way.
The completed proposed project will retain the substantial existing intervening 60-foot-wide area of parking
lot driveway aisle and vertical curbing between Wetland A and the closest point of the proposed building
addition (the building addition’s northeast corner)—see attached EXHIBIT 2 and EXHIBIT 3, which
Halinen Law has created on Cornerstone Architectural Group’s 05-10-2017 U.S. Bank Expansion overall
parcel site plan sheet A1.0 and project site plan sheet A1.1, respectively. Because of the combined width
of the retained pavement and vertical curbing and the 6” height of the retained vertical curbing, those
substantial existing intervening improvements will separate the subject building addition project site
property from the Wetland A critical area.
No lowering of the existing surface grade within the area of the existing intervening pavement and curbing
between the building addition and Wetland A is proposed. (Nor is lowering of the existing surface grade
proposed anywhere else within Lot 3’s east parking lot.) The proposed retention of the intervening
