Lake Washington Loop Trail — Phase 3
Otak Project No. 32468
December 2016
Description of Project:
The purpose of the Lake`�'ashington Loop Trail Project is to design and e�rentually build a 7,000
lineal feet regional trail facility to connect the existing Lake��'ashington Trail from the Logan
A�Tenue/Cedar River junction to a ne�v trail at Rainier A�renue North. The project will complete a
missing gap in the regional trail sj�stem. The Phase 3 segment of the proposed trail�vill be primaril5�
located on the north side of Airpart�`'ay and�vill extend north along Logan Avenue to connect to
the ezisting Cedar River Trail. The Phase 3 segment�vill end near the intersection of Rainier r��renue
N. and�vill include a connection to the existing Perimeter Road. The trail segment along Airport
��'ay�vill be an interim solution and�vill include a cycle track to miniinize impacts to the existing
road�vay and right-of-way. The cycle track is proposed to be an interim solution until the Renton
l�Tunicipal Airport finalizes their comprehensive master plan for zoning and use requirements along
Airport��'ay. The Phase 3 trail will accommodate pedestrians,runners,bicyclists, and other non-
motorized trail users. The trail will be designed to be accessible. Key project elements include:
• A 2,500 LF segment of regional trail
• 12 foot�vidth asphalt concrete pavement trail or 9 foot�vidth cycle track
• Enhanced bridge crossing over the Cedar River
• Connections to the Cedar River regional trail
• Pedestrian connections to the downto�vn core
• Coordination��ith Renton Municipal Airport
• Street crossings and dri�-e�vay crossings
• Storm��ater management
• Enhanced aesthetics,hardscape,landscape, and interpretive/�vayfinding
• Utilit�� coordination
• Federal funding— (FHWA funding included)
• Anticipated construction cost of$1.5 to $2.0 million
Following is the proposed scope of work for final design/engineering of the Lake"'ashington Loop
Trail—Phase 3.

Lake Washington Loop Trail - Phase 3
Renton, Washington
File No. 0693-077-00
INTRODUCTION
GeoEngineers, Inc. (GeoEngineers) is pleased to present this Contract Amendment No. 1 for geotechnical
engineering services to support geotechnical design for Phase 3 of the planned Lake Washington Loop
Trail in Renton, Washington. The Phase 3 portion of the project will consist of improvements for segments
of the regional trail along Logan Avenue North and Airport Way.
GeoEngineers previously completed preliminary geotechnical engineering services for 30 percent design
of the trail project,the results of which are presented in our report dated May 6, 2016.
We understand the Phase 3 portion of the project will include installation of a multi-use trail and bicycle
lane with connections to other trails and crosswalks at roadway intersections along Logan Avenue North
and Airport Way. The proposed connection to the Cedar River Trail in the vicinity of Logan Avenue North
will include modifications to an existing roadway bridge over the Cedar River. Existing pavement and
sidewalks along Logan Avenue North and Airport Way will be modified. New street lighting along Logan
Avenue North and pedestrian signal systems at two intersections (Airport Way/Logan Avenue North and
Airport Way/Shattuck Avenue South)will be constructed.
SCOPE OF SERVICES
The purpose of our geotechnical consulting services is to evaluate existing site conditions as a basis for
establishing geotechnical criteria and recommendations for design of the Phase 3 portion of the trail
alignment. We will evaluate subsurface conditions by reviewing existing information and by observing
conditions encountered in excavations ("potholes") made by others to locate and identify underground
utilities along the alignment.
Otak,Inc. 'September 23,2016 Page 2
Our specific scope of services for Phase 3 design includes the foilowing:
1. Review available geologic and geotechnical information for projects we and others have completed
alongthe Phase 3 alignment,as appropriate.
2. Observe subsurface conditions encountered in utility potholes along the alignment. The utility
potholes will be coordinated by Otak, Inc. (Otak). Our representative will observe the potholing on a
full-time basis at selected locations near pianned light pole foundation locations, and will obtain
representative soil samples, classify the soils encountered, record groundwater conditions (if
encountered),and prepare a detailed log of each pothole.
3. Evaluate pertinent physical and engineering characteristics of the near-surFace soils based on
existing data and the pothole explorations. We anticipate the laboratory test program will consist of
moisture content and gradation (sieve analyses)tests,as appropriate.
4. Develop recommendations for foundation support of new light and pedestrian signal poles, including
bearing pressure, embedment depth, minimum diameter, lateral resistance and settlement
estimates.
5. Comment on anticipated construction issues related to pole foundation installation such as the
potential for caving soils and groundwater.
6. Provide recommendations for underground utility installation, including backfilling and compaction
criteria.
7. Attend one project team meeting to discuss our findings and present our preliminary
recommendations for pole foundation design.
8. Prepare a written report in both draft and final versions containing our findings, conclusions and
recommendations.
Our services will be provided as an amendment to an existing Subconsultant Agreement between
GeoEngineers and Otak dated September 23, 2015. The agreement includes negotiated hourly rates
based on a 2014 Washington State Department of Transportation (WSDOT) audit. Exhibit A summarizes
our fee estimate based on these rates. A breakdown of hours for the services described above is
presented in Exhibit B. We understand additional geotechnical design services will be requested for
subsequent design phases for this project in the future. Please contact us if you have questions regarding
the proposed scope of services or fee estimate.
Sincerely,
GeoEngineers, Inc.

SCOPE OF SERVICES
Lake Washin�ton Loop Trail—Phase 3 Final Desi�n
PROJECT DESCRIPTION
The following is TENW's proposed Scope of Services for Phase 3 of the Lake Washington Loop Trail project.
This scope assumes that design will be progressed to final design with submittal levels at 60%/90%Bid,with
the project to consist of the following general improvements:
o Regional Trail along Logan Avenue S.,and Airport Way
o Cedar River Bridge Crossing
o Connections to Cedar River Trail
o Enhanced Pedestrian Connections to downtown core
o Street and Driveway Crossings
o Traffic Signal modifications at Logan/Airport and Airport/Shattuck necessary to
accommodate trail crossings.
SCOPE OF SERVICES
Below is a summary of task items that the TENW team will provide for this scope of services:
Task 1:Proiect ManaQement and Coordination
1.1 Scope: TENW will provide project management and coordination services, and will
attend project team/agency coordination meetings as follows:
Deliverables:
• Project coordination meetings with City(Assume 4 meetings)
• Stakeholder/Agency Meetings(Assume 1 meeting)
Task 2:Final DesiQn/EnQineerinQ
2.1 Scope: TENW will prepare illumination, and traffic signal construction documents for
60%/90%Bid submittal levels as necessary to accommodate new trail. TENW will
evaluate trail lighting along the Cedar River focused on light spillover associated with
proposed bridge lighting. TENW will also provide assistance to the team with respect to
channelization/t►orizontal alignment. Documents will include signal phasing, signal
heads, pedestrian heads, placement of poles, conduit, junction boxes, general wiring,
interconnection,and other associated elements.
Deliverables:
�TENW 1 September 19, 20�6
