III. DESCRIPTION/BACKGROUND
SR 520 Trail Grade Separation Project at NE 40th Street
This project will improve safety and operations for all users at the intersection of the SR 520 Trail and NE 40th Street by grade separating non-motorized users from vehicle traffic. A tunnel will be constructed underneath 40th Street for pedestrians and bicyclists and associated infrastructure improvements will connect the 520 Trail to the tunnel. Specific benefits of the project include:
• Improved safety for the high volume of pedestrians and bicyclists currently using the at-grade trail crossing, which conflicts with both through and turning traffic on NE 40th Street;
• Improved operations for vehicles and buses by reducing the number of pedestrians and bicycle crossing NE 40th Street; and
• Safe and efficient path for pedestrians and bicycles needing to cross NE 40th Street.
Please see Attachment A for a vicinity map.

Project Schedule and Coordination with Downtown Redmond Light Rail Extension
Construction of the Grade Separation project tunnel is scheduled to be substantially complete before construction begins at NE 40th Street for the Sound Transit Light Rail Extension from Overlake to Downtown Redmond. Remaining portions of the Grade Separation project are scheduled to be substantially complete by January 2021.
Below is a table showing the construction schedules for these two projects:

The tunnel construction for the Grade Separation project will occur on the west side of the SR 520 interchange at NE 40th Street, requiring a full closure of NE 40th Street at this location. The Downtown Redmond Light Rail Extension will require a partial closure on the east side of the SR 520 interchange at NE 40th Street. The City needs to avoid overlapping lane closures between the two projects, which is accomplished with the schedule above.

V. IMPACT
A. Service/Delivery:
The recommended actions will enable construction of the Trail Grade Separation project on schedule.
The Governor issued a Proclamation on March 23 Stay Home/Stay Healthy, requiring residents to stay home except as needed to maintain continuity of operations of essential critical infrastructure sectors. Under this order, the City’s 40th Street Trail Grade Separation Project and Sound Transit’s Light Rail extension projects are considered critical infrastructure projects, and therefore work will continue on both projects.
B. Fiscal Note:
The low bid is approximately $1.4 million below the Engineer’s estimate. The project funding and costs have been revised to reflect the actual bid price, including revised staff costs and contingencies that result from revised costs. The total project cost is nearly $2 million less than the estimate of $16.2 million that was provided to the Planning and Public Works Committee-of-the-Whole on February 11, 2020, before the bids were received.
Prior estimates of Community Facilities District 2016-1 funding included a higher dollar amount due to the uncertainty of project costs. Funding from the CFD reflects the amount of money needed to complete the project.
Additional State funding of $1.8 million from the Connecting Washington Transportation package is included in the adopted Supplemental Transportation Budget approved by the Legislature and included in the funding for this project.
Current funding and estimates costs for the project are below:
Current Project Budget:
Connecting WA Transportation package $10,589,302
Community Facilities District (CFD) 2016-1 $ 1,494,352
Additional State Funding from Connecting WA $ 1,818,277
Transportation CIP $ 360,000
Total Funding $14,261,931
Estimated Project Costs:
Preliminary Design Phase $ 441,639
Design Phase $ 1,428,191
Right-of-Way $ 64,164
Construction Phase $12,327,937
Total Estimated Project Cost $14,261,931
VI. ALTERNATIVES TO STAFF RECOMMENDATION
If the project is not constructed, the City will need to repay the State approximately $1.5 million that has been spent on design.
VII. TIME CONSTRAINTS
In order for Granite Construction to meet the construction schedule, the contractor must order steel pilings needed for construction of the tunnel portion of the project. These steel pilings need to be ordered immediately due to the lead time required to fabricate and deliver these to the jobsite. The contract with Granite Construction needs to be approved by Council so contractor can start the order process.
This project needs to begin construction in the Spring 2020, including ordering needed materials, so work on the Grade Separation tunnel can be substantially complete before construction begins at NE 40th Street for the Sound Transit Light Rail Extension from Overlake to Downtown Redmond. If the project does not meet this schedule, it will be at risk of delay up to two years due to the construction of the Sound Transit Downtown Redmond Light Rail Extension and cost increases due to the delay.
