EXHIBIT A
SCOPE OF SERVICES
FINAL DESIGN/ENGINEERING SERVICES
City of Renton, Washington
Lake Washington Loop Trail Phase 3 Supplement No. 9
Otak Project No. 32468
October 2020
Description of Project:
The purpose of the Lake Washington Loop Trail Project is to design and eventually build a 7,000
lineal feet regional trail facility to connect the existing Lake Washington Trail from the Logan
Avenue/Cedar River junction to a new trail at Rainier Avenue North. The project will complete a
missing gap in the regional trail system. The Phase 3 segment of the proposed trail will be primarily
located on the north side of Airport Way and will extend north along Logan Avenue to connect to
the existing Cedar River Trail. The Phase 3 segment will end at the intersection of Rainier Avenue
North. The trail segment along Airport Way will be an interim solution and will include a cycle track
to minimize impacts to the existing roadway and right-of-way. The cycle track is proposed to be an
interim solution until the Renton Municipal Airport finalizes their comprehensive Master Plan for
zoning and use requirements along Airport Way. The Phase 3 trail will accommodate pedestrians,
runners, bicyclists, and other non-motorized trail users. The trail will be designed to be accessible.
The Supplement No. 9 scope of work provides additional services including the following:
Project Management and Coordination (Extended Design Schedule)
Airport Way and Logan Avenue Intersection Revisions (Revise from Draft 100% Level)
Logan Avenue Grade Adjustments (Revise from Draft 100% Level)

2.2 Logan Avenue Grade Adjustments (Cedar River)
OTAK will prepare 100% PSE for revised layout and grade adjustments along Logan Avenue near
