At 1-405, near Oakesdale Avenue. At SR-167, near SW
41 st Street interchange and near SW 19th Street. All within
WSDOT right-of-way.
PROPOSAL: Excavation of two "pot holes" at each lltility crossing
locati~ithin the WSDOT right-of-way. One pot hole will be made on each side of the highway
so th a Z survey can be done on top of the exposed underground utility pipe. The purpose
of the s y is to determine the' exact location, depth, and grade of the pipe. The SR 167 pot
holes will be located in the fill prism off the edge of the paved shoulder. The 1-405 pot holes will
be located in a flat graded area near an existing walkway under the Springbrook Creek side
channel bridge. '
The operation is as follows: The field crew digs out a plug of soil and sets it aside. They then
use injected air and vacuum hose from a work truck to remove the soil, creating a narrow
vertical hole in the soil, similar to a soil boring. The removed soil is kepfin an enclosed
container. The final depth'of thewe is equal to the depth of the top of the now-exposed utility
pipe. Once the top of the utility I 's exposed; an XYZ survey of the utility pipe is performed.
After the XYZ survey the crew pia the soil back into the hole, tamps the soil tightly into the
hole and places the sod plug back in place. Due to the length of the vacuum hose, the work
truck can be parked up to 100 feet away from the data collection location.
Once the data' collection is completed, the area will be restored to' its pr~ta collection
condition and the work truck will be removed from the site. All work will be pe~-ed within the
WSDOT right-of-way.

Re: Shoreline Substantial Development Permit (SSDP) Exemption and Critical Areas Exemption
request for proposed underground utility as-built data collection activities to be located within 200
feet of Springbrook Creek and Panther Creek.
Dear Ms. Ding:
The Washington State Department of Transportation (WSDOT) 1-405 Project Team is currently
designing traffic improvements for the 1-405 corridor within the jurisdictional boundaries of the
City of Renton. Additional underground utility as-built information regarding the exact location of
existing underground utilities is required to complete ongoing design documents. The 1-405 Project
Team proposes to collect this field data to assess the design elements for the protection of existing
underground utilities within the WSDOT right-of-way (ROW) as part of the 1-405 Renton Nickel
Improvement Project.
Attached to this letter is a detailed description of the. proposed as-built data collection activity. Also
attached is a set of drawings that includes a vicinity map, site plan and legal description of the site
parcels. The location of each proposed data collection site within critical area buffers and the
regulated shoreline of Springbrook Creek are described below:
c:::..
Ii) Two pot holes are proposed at the underground utility crossing of a King County 160"
sanitary sewer line under 1-405 at milepost 1.55, parallel to Springbrook Creek near
Oaksdale Avenue. The pot holes will be located directly over the existing utility line. The
pot holes are outside of the ordinary high water mark (OHWM) of Springbrook Creek, but
are within the 200' shoreline zone of Springbrook Creek (see attached drawings).
e Two pot holes are proposed at the underground utility crossing of a Seattle Public Utilities
60" water line under SR-167 at milepost 25.67, near the main channel of Panther Creek and
Panther Creek wetlands. The pot holes will be located directly over the existing utility line
and within the fill prism of SR -167. No work will occur within the OHWM of the stream
or within wetlands (see attached drawings).

Since the proposed work is located within critical area buffers and the regulated shoreline boundary
of Springbrook Creek, WSDOT requests a Critical Areas Exemption and Shoreline Substantial
Development Penhit (SSDP) Exemption from the City of Renton to perform this underground
utility as-built data collection activity. The activity constitutes "research and site investigation" and
is, therefore, exethpt from the standard requirements of the Critical Areas, Ordinance per RMC' 4-
03-0S0(C)(S)(b)(ii). The proposed data collection activity is also exempt from the Shoreline
Development Permit process based' on RCW 90.S8.030(3)(e)(xi), which states that: " ... The
following shall not be considered substantial developments for the purpose of this chapter:
(xi) Site exploration and investigation activities that. are prerequisite to preparation of an
application for development authorization under this chapter, if:
(A) The activity does not interfere with the normal public use of the surface waters;
(B) The activity will have no significant adverse impact on the environment
including, but not limited to; fish, wildlife, fish or wildlife habitat, water quality,
and aesthetic values;
(C) The activity does not involve the installation of a structure, and upon
completion of the activity the vegetation and land configuration of the site are
restored to conditions existing before the activity."
The proposed data collection activity will not interfere with normal public use of Springbrook
Creek. The proposed activity does not involve the installation of a structure, and upon completion
of the activity the vegetation and land configuration of the site are restored to conditions existing
before the activity.
The data collection activity will have no significant adverse impacts on the environment based on '
the following:
69 The time duration of the activity is limited. The underground utility as-built data collection
activity will be completed in less than 10 work days.
Cl The data collection activity within critical area buffers and shorelines has been minimized
to the greatest extent feasible (only 1 data collection location is within a regulated shoreline
and no data collection location is in a stream or wetland.).
e No trees are anticipated to be removed as a result of data collection activities ,unless
unforeseen site conditions arise during onsite operations.
Q The data collection locations are in areas that are easily accessible by the work vehicles.
" No structure will be installed as part of this project.
Ii) The least damaging method will be used for this type of data collection to minimize
vegetation and soil disturbance in each location.
Page 3 of5
Q Data collection locations have been placed as far away as possible from the Ordinary High
Water Mark (OHWM) of Springbrook Creek. In addition, all data collection locations are
outside the OHWM of streams and outside wetland boundaries.
WSDOT has determined that the proposed data collection activity is also exempt from SEP A under
WAC 468-12-800(3), which exempts "Information collection and research, as provided by WAC
197-11-800(18), including but not limited to the development, adoption, and revision of
transportation plans and six-year construction programs, arid any other studies, plans, and programs
which lead to proposals which have not yet been approved, adopted, or funded, and which do not
commit the transportation department to proceed with the proposals contained therein."
Please accept this letter as an official request from WSDOT for an exemption from both the
standard Critical Areas review requirements and a Shorelines Substantial Development Permit for
this underground utility as-built data·collection activity. Thank you in advance for taking the time
to process our request. If you have any questions, please feel free to contact Terry Drochak at (425)
456-8595 or e-mail terry.drochak@i4~5.wsdot.wa.gov.

Attachment 1:
Description of Project Activity:
This work would involve the excavation of two "pot holes" at each utility crossing location within
the WSDOT ROW. One pot hole will be made on each side of the highway so that a XYZ survey
can be done on top of the exp~sed underground utility pipe. The purpose of the survey is to
determine the exact location, depth, and grade of the pipe. The SR 167 pot holes will be located in
the fill prism off the edge of the paved shoulder. The 1-405 potholes will be located in a flat graded
area near an existing walkway under the Springbrook Creekside channel bridge.
The operation is as follows: The field crew digs out a plug of sod and sets it aside. They then use
injected air and vacuum hose from a work truck to remove the soil, creating a narrow vertical hole
in the soil, similar to a soil boring. The removed soil is kept in an enclosed container. The fmal
depth of the hole is equal to the depth of the top of the now-exposed utility pipe. Once the top of
the utility pipe is exposed, an XYZ survey of the utility pipe is performed. After the XYZ survey
the crew places the soil back into the hole, tamps the soil tightly into the hole and places the sod
plug back in place. Due to the length of the vacuum hose, the work truck can be parked up to 100
feet away from the data collectiori location.
Once the data collection is completed, the area will be restored to its pre data collection condition
and the work truck will be removed from the site. All work will be performed within the WSDOT
right-of-way.
BEST MANAGEMENT PRACTICES (BMPs):
Actions taken to avoid and minimize potential impacts during data collection activities include the
following BMPs:
~ The time duration of the activity is limited. The underground utility as-built data collection
activity will be completed in less than 10 work days.
o The data collection activity within critical areas and shorelines has been minimized to the
greatest extent feasible (only 1 data collection location is within a regulated shoreline and
no data collection location is located in a stream or wetland.).
e No trees are anticipated to be removed as a result of data collection activities unless
unforeseen site conditions arise during onsite operations.
e The data collection locations are in areas that are easily accessible by the work vehicles .
., No structure will be installed as part of this project.
6) The least damaging method will be used for this type of data collection to minimize
vegetation and soil disturbance in each location.
e Data collection locations have been placed as far away as possible from the Ordinary High
Water Mark (OHWM) of Springbrook Creek. In addition, all data collection locations are
_ outside the OHWM of streams and outside wetland boundaries.
