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 near the intersection of Rainier Avenue N. and will include a connection to the existing Perimeter Road. 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. 5 scope of work provides additional services and changes to the 60% design, including the following: • Rainier Avenue Feasibility Study and Grant Support • Development of Alternative Cycle Track Plan Concept • Airport Way and Logan Avenue Intersection Feasibility • Extension of Design Period—approximately 18 months • Final Design Revisions to 100%PSE of Alternative Cycle Track Plan and Airport Way/Logan Avenue Intersection Improvements 1.0 PROJECT MANAGEMENT AND COORDINATION 1.1 Coordination with City of Renton OTAK will coordinate with the CITY of Renton on a regular basis to keep the CITY's project manager informed about project progress,project issues and schedule. OTAK will assist in scheduling project related meetings,reviews, and other coordination activities needed to keep the City of Renton — Lake Washington Loop Trail 1 otak K:A project\32400\32468\Contract\Supplement 5\Scope_Supplement 5_102918.doc Exhibit A-6 — Scope of Work Continued project moving forward. Regular communication with the CITY will occur on a weekly basis (by phone,regular meetings as described below, and/or by e-mail). Supplement No. 5 will extend Task 1.1 approximately 18 months. 1.2 Project Coordination Meetings with City (Assume 6 meetings) Project coordination meetings with CITY Staff will occur approximately monthly to review progress,to discuss project related issues, to review schedule, and to discuss current topics. Supplement No. 5 will include up to six (6) additional coordination meetings to be held during the final design period for Phase 3. Attendance will generally include OTAK's project manager and project engineer along with designated CITY Staff. 1.3 Project Monitoring and Reporting Project management will include the coordination of design team members,internal project scheduling,and the preparation of a monthly progress report and a monthly billing statement. Supplement No. 5 will extend Task 1.1 approximately 18 months. Deliverables • Monthly progress report and monthly invoice,per City of Renton requirements (monthly) 2.0 SUPPLEMENTAL DESIGN TASKS 2.1 Rainier Avenue Feasibility OTAK will update the preliminary design concepts developed as part of the Design Report to consider and determine the feasibility of a more compact cycle track solution along Rainier Avenue. Work will include preliminary engineering and layout/development of an alternative plan concept and roadway sections. The concept plan and sections will be used to support a funding/grant application being made by the City. Updated construction cost estimates will also be prepared for the updated concept plan. Deliverables • Updated Rainier Avenue Concept Plan—graphic roll plot • Updated Rainier Avenue Roadway Sections • Updated Rainier Avenue Concept Construction Cost Estimate 2.2 Alternative Cycle Track Plan Concept OTAK will update the 60% PSE layout to develop an Alternative Trail/Cycle Track Plan to minimize or avoid the need for right-of-way acquisition. The existing (60% PSE) regional trail section will be revised to extend the cycle track around the Logan Avenue/Airport Way intersection to create a more compact layout. The concept plan will be used to revise the right-of-way needs for the project. City of Renton — Lake Washington Loop Trail 2 otak K:Aproject\32400\32468\Contract\Supplement 5\Scope_Supplement 5_102918.doc Exhibit A-6 — Scope of Work Continued Deliverables • Updated Cycle Track Concept Plan 2.3 Airport Way and Logan Avenue Intersection Revisions OTAK and TENW will prepare alternative intersection concepts for the Airport Way and Logan Avenue intersection to provide improved pedestrian crossing accommodations. The proposed intersection improvements will include revisions to layout/medians, signing, striping, and signal system. There will be two (2) concepts developed—one that focuses on just the pedestrian crossing and a second that focuses on the full intersection and traffic movements through the intersection. Preliminary construction cost estimates will be developed for the concepts developed. Deliverables • Airport Way and Logan Avenue Intersection Revisions —Two (2) Alternative Concept Plans 3.0 FINAL DESIGN REVISIONS 3.1 Design Revisions—60% PSE to 100% PSE OTAK will prepare 90% level and 100%level civil design plans for the proposed Phase 3 trail alignment,including City directed design revisions. The design will include trail, sidewalk, cycle track and roadway improvements along Airport Way and Logan Avenue along with intersection improvements and pedestrian/bicycle connections within the project limits. The plans will include the revisions described in Task 2.2. Plans will be prepared to current CITY of Renton standards. Plans will be prepared at a horizontal scale of 1-inch = 20 feet and a vertical scale of 1-inch = 5 feet. Deliverables • Civil Design Plans with Revisions —90% and 100% Level 3.2 Airport Way and Logan Avenue Intersection Revisions OTAK and TENW will prepare 90% and 100%PSE for the alternative intersection concept developed for the Airport Way and Logan Avenue intersection to provide improved pedestrian crossing accommodations. The proposed intersection improvements will include revisions to layout/medians, signing, striping, and revisions to the existing signal system. Deliverables • Airport Way and Logan Avenue Intersection Revisions—90% and 100% Level 3.3 Design Review/Coordination Meetings (Assume 4 meetings) Design meetings will be held on a regular basis with the CITY to discuss project issues during the City of Renton — Lake Washington Loop Trail 3 otak K:A project\32400\32468\Contract\Supplement 5\Scope_Supplemcnt 5_102918.doc Exhibit A-6 — Scope of Work Continued design process. It is anticipated that up to four (4) additional design meetings will be held during the final design period. 3.4 Design Schedule Extension The design period for the project is being extended approximately 18 months. The 60% PSE for the project was completed in July 2017. Task 3.4 includes time to review the 60% PSE and previous City review comments and to re-mobilize the design team to move forward to 90% PSE,including the revisions described above.
