PERMISSION FOR RIGHT-OF-ENTRY TO CEDAR RIVER TRAIL
Dear Mr. Baldi:
The City of Renton Community Services Department hereby permits King County(Permittee), its
engineering consultant Shannon & Wilson, Inc. (S&W) and S&Ws subcontractors to enter the
Cedar River Trail for the purpose of a field investigation consisting of site reconnaissance,
topographic surveying, and drilling two (2)to four(4) geotechnical borings, in the general location
shown in Figure 1, 'Proposed Exploration Area,' subject to and per the terms specified below and
described in Figure 4.
Permittee's Representations
Purpose of Permittee's work:
As a part of a hazard assessment and risk analysis study, S&W intends to evaluate certain
conditions on the left bank of the Cedar River Trail Site A (CRT-A) (RM 2.4 -2.5), Renton,
Washington (approximately 0.8 miles upstream of 1-405).
To complete this evaluation, S&W and its subcontractors will complete geotechnical explorations
to collect subsurface information at the site. Holt Services, Inc. (Holt) is under subcontract to
S&W to complete the explorations, and Advance Government Services (AGS) is under
subcontract to S&W to provide flagging and traffic control. The explorations shall consist of drilling
two(2)to four(4)geotechnical borings on the north shoulder of the CRT at RM 2.4 to 2.5. Cultural
Resource Consultants, LLC (CRC) is under subcontract to S&W to provide cultural resources
monitoring of the samples and material removed from the explorations. Subsurface data gathered
from the geotechnical explorations will be used to develop subsurface interpretations for use in
later analyses. CRC will complete a monitoring report that meets the Washington Department of
Archaeology and Historic Preservation's reporting standards and create a new project in
WISAARD. Pacific Geomatic Services, Inc. (PGS)will complete a topographic survey of the slope
above the trail.
S&W walked the site with City of Renton representatives on November 13, 2019 to evaluate site
access, discuss proposed site activities and subsurface investigation plan details. The following
details reflect permissible actions based on that site walk.
Permittee will perform work as follows:
1055 South Grady Way,Renton,WA 98057- rentonwa.gov
• S&W will meet with Holt, CRC, PGS and AGS at the Cedar River Trailhead near the
underpass at 1-405 on the morning of December 9, 2019.
• S&W and its subcontractors will proceed to the City of Renton's laydown and storage area
north of the Dog Park, to park non-essential vehicles and materials (See Figure 1 and,
more specifically, Figure 3).
• AGS will provide two flaggers for traffic control while the drill rig and support vehicle(s) are
mobilizing along the trail to the site and while the explorations are being completed.
• While Holt moves the drill rig to the planned exploration locations, it is anticipated that one
lane of the trail shall remain open. Drill rig dimensions are provided in Figure 2. AGS will
assist pedestrians navigating around the drill rig.
• Holt will position the drill rig toward the river-side trail shoulder at the exploration locations
such that one lane of the trail remains open.
• AGS will place traffic control around the work area in general accordance with the FHWA
Manual on Uniform Traffic Control Devices (MUTCD). Traffic signs and channelizing
devices shall be illuminated as to be visible in low-light and night time conditions.
• Holt will use a utility vehicle to move supplies from the laydown yard/support vehicle to the
exploration locations.
• A representative from S&W will be on site to supervise drilling activities and document
subsurface conditions.
• At the end of each shift Holt will lock and secure the drill rig and tools, remove equipment
keys, and place a locked chain-link fence perimeter around the equipment. Illuminated
traffic control devices shall remain in place.
• A minimum of two days and a maximum of four days are required to complete the
exploration program.
• At the end of the exploration program Holt will walk the drill rig back to the laydown and
storage area, and one lane of the trail shall remain open. Flaggers from AGS will assist
trail users in navigating around the drill rig.
The Permittee will adhere to the following:
• While conducting the work, permittee, S&W, and S&W subcontract representatives must
wear identifiable, bright-colored vests;
• Permittee will minimize impacts to flora and fauna to the maximum extent possible;
• Permittee will minimize profiles of above-ground caps and monitoring equipment in boring
holes to the maximum extent possible to avoid trip and trail hazards to trail users.

DESCRIPTION OF WORK/PROJECT OBJECTIVES
This hazard assessment and risk analysis study will assess and characterize existing flood and landslide hazards and risks,
and their interactions on the left bank of the Cedar River Trail Site A(CRT-A) (RM 2.4-2.5), Renton, Washington
(approximately 0.8 miles upstream of I-405). In the event that substantial risks are present, a feasibility study to develop
potential alternatives to address those risks may be conducted under a separate work order.
The CRT-A area is identified in King County Flood Control District's(District) Cedar
River Capital Investment Strategy (CIS),passed by District Executive Committee Motion 2017-03. Approximately 200
feet of bank erosion to CRT-A was identified during the 2017 CIS process and while conducting the 2018 annual facility
low-flow inspections just upstream at the Haddad revetment; however, the exact extent of newly eroded areas is unknown
at this time. A site reconnaissance conducted in January 2019 by River and Floodplain Management Section(RFMS) staff
identified two areas of slope failure below the trail and along the river bank. Tension cracks observed in the trail
downstream of the erosion identified during the CIS process appear to be associated with adjacent bank/slope movement.
An active shallow bedrock landslide and active rock-fall were observed on the slope above the trail.
Under this work order the Consultant will conduct field investigations, laboratory testing, and slope-stability modeling to
characterize conditions and assess slope stability hazards in the trail embankment and the hillslope above the trail. To the
extent that slope instability hazard(s)exist,the consultant will assess potential risks to structures and property, landslide,
and landslide-channel interaction hazards.

Subject:Cedar River Trail Site A Information
Hi Amanda,
Attached is a map showing the location of the feasibility study. The consultant will be working up the exact locations of
the borings which I expect to be included in the Right-of-Entry request.
I hope we are able to connect next week to discuss the project and the permits we will need. In addition to the task
below,we are conducting a slope stability analysis but the consultants will be using HOAR and I think a drone survey and
i
special software. The end result will be a hazard and risk assessment of the slope,trail, and erosion we identified along
the river.
Below is information regarding the borings currently scheduled to take place on Dec 9(I pulled this from the consultants
scope of work).
Task 2—Cedar River Trail Embankment Subsurface Exploration
Task Description: The Consultant shall collect subsurface information to inform embankment slope stability assessment
described under Task 3. Subsurface exploration will consist of at least two and up to four borings. Contingent upon the
variability of the subsurface information encountered in the first two borings, a third and fourth boring may be drilled to
characterize the site subsurface conditions.
The Consultant shall:
• Perform a site reconnaissance of the left bank erosion and/or instability sites and confirm their
extents based on visual observation and County survey/topography. Reconnaissance to include:
o Ground surface observations along the trail and left bank accessible by foot.
o Left bank erosion observations accessible by boat, should conditions preclude safe access by
foot.
• Using the information from the site reconnaissance, and working with the County, develop two
boring locations for subsurface exploration. Include third and fourth boring locations as a contingency
if the subsurface conditions are variable.
• Drill up to four borings, each to a total depth of up to 50 feet, including 10 feet into bedrock. The
total depth of borings shall be determined based on data needs in subsequent tasks.
• Provide an on-site geologist or geotechnical engineer to log and obtain soil samples at 21/2-foot
intervals to 30 feet, and then at 5-foot intervals thereafter.
• Perform laboratory index testing of subsurface samples as needed to inform slope stability
analysis. Testing to include
o Moisture content analyses—up to 40 samples
o Grain size analyses—up to 12 samples.
o Atterberg limits plasticity analyses—up to 6 samples.
• Retain and store all samples for up to one year.
• Develop a temporary traffic control plan and provide for flagger(s) to control pedestrian and bicycle
traffic on the trail at all times when heavy equipment is in operation within the trail right-of-way.
Borings within the trail corridor should avoid impacting the paved trail surface and must be
performed in a manner that maintains safe pedestrian and bicycle use of the trail with no more than
a 20-minute delay to trail users. A rubber-track rig and mud mats will be used to minimize impacting
the trail pavement when moving the rig and during drilling.
• The borings shall be backfilled according to Washington State regulations using bentonite pellets. At
the surface, the final 1- 2 feet of the boring will be backfilled with gravel followed by patching of the
trail surface with cold-mixed asphalt.The Drilling Contractor will place auger cuttings in 55-gallon
drums during exploration, and remove and dispose of the cuttings off-site after drilling is complete.
The surface of the asphalt will be swept clean after drilling is complete.
2
■ A groundwater monitoring well consisting of a vibrating wire piezometer and data logger will be
installed in two of the borings. Well monuments will be constructed flush with their
surroundings. The Consultant will download the groundwater monitoring data two times for this
work order.
■ Prepare and submit the appropriate Notice of Intent forms to the Department of Ecology prior to the
start of drilling. Consultant shall be responsible for preparing and submitting boring and well
construction logs to the Department of Ecology.
■ Arrange all required utility location services.
■ Prepare a contingency plan for unexpected discovery such as potentially contaminated soil.
■ Provide cultural resources monitoring by a professional archaeologist during the drilling.The
professional archaeologist shall complete a monitoring report that meets the Washington
Department of Archaeology and Historic Preservation's reporting standards.The archaeologist shall
screen excavated sediments (as necessary) through
%-inch mesh. Artifacts shall be recorded in the field (photographed, basic attributes described),
placed in bags in the hole(s) in which they were found; and detectable tape or metal tags placed with
the artifact bags.The professional archaeologist shall complete a monitoring report that meets the
Washington Department of Archaeology and Historic Preservation's reporting standards, create a
new project in WISAARD, upload the report, and add the King County Historic Preservation Program
as an Organization with Editor Access in the project.The monitoring report shall include a USGS
topographic map and an aerial photograph showing the area monitored, and summary stratigraphic
information for the area monitored. The report shall rely on Sonja Kleinschmidt Kopperl et al.'s (2016)
"Archaeology of King County, Washington: A Context Statement for Native American Archaeological
Resources" (NADB 1688468) and Boswell's (2017) King County Historic Settlement Context 1850-1920
(NADB 1691230)for relevant general background information. In the event an archaeological site is
found, no additional disturbance to the site will occur without a DAHP permit, which would be
obtained at a later date and scope.
Requirements:
■ The borings shall be performed between 8:00 a.m. and 6:00 p.m., and during daylight hours only,
Monday through Friday.
■ Equipment remaining on site for the duration of exploration activities shall be secured with locked
temporary chain-link perimeter fencing during off-work hours.
■ The exploration locations will be cleaned and restored to the extent specified in the permits, except
for repaving completed by the County.
■ Exploration spoils from the drilling operations will be drummed and disposed of offsite. The spoils are
assumed to be non-hazardous.
■ Boring equipment shall access the site as it currently exists. Ramps, roads, or other access
requirements shall not be constructed.Vegetation clearing needed for access shall be done by hand,
without mechanized equipment.
Assumptions:
■ The County will provide one set of consolidated comments on the draft monitoring report within two
weeks of receipt, and one report revision will occur.
3
■ The County-specified hollow-stem auger drilling method will be capable of drilling to the required
depth through embankment fill and native soil to the top of bedrock.
■ The decision to complete either one or two additional borings will be made via verbal County
authorization at the completion of the second and potentially third boring such that drilling and
support services will be under a single mobilization.
■ The County will provide preliminary geomorphic site assessment in PDF format.
■ Any revegetation necessary as a result of this work will be performed by the County.
■ Any repairs to the trail pavement as a result of this work will be performed by the County.
■ The County will furnish the letter of conditions to conduct borings in the trail right-of-way, permission
from the landowner, and the Shoreline Exemption documentation from the City of Renton. It is
assumed no other permits are needed.
■ Right-of-entry shall be coordinated with and provided by the County.
Deliverables:
■ Site map showing planned boring locations.
■ Traffic control plan for trail pedestrian traffic.
■ Unexpected discovery plan.
■ Draft and final cultural and archeological field monitoring report.
■ Draft boring logs (deliverable date: two weeks after exploration fieldwork completed).
