SUMMER 2018

WELCOME/BIENVENIDO ///

Moving forward together

Lynnwood Link Extension

SUMMER 2018

The Lynnwood Link Extension is a key part of Sound Transit’s mass transit system

expansion approved by voters. Targeted for operation in 2024, four new stations and

8.5 miles of light rail will connect north Seattle, Shoreline, Mountlake Terrace and

Lynnwood with the entire region.

Schedule

At Sound Transit, sustainability is about making long-term investments and choices

that keep the region’s environment, communities and economy healthy. The agency

encourages sustainability by providing affordable, environmentally friendly travel

options that connect people to where they live, work and play.

SYSTEM EXPANSION

Sound Transit system expansion is:

• Building a 116-mile network extending regional light rail from Tacoma to Everett,

and from densely developed Seattle neighborhoods to Redmond and Issaquah,

and extending Tacoma Link.

• Establishing Bus Rapid Transit to the north, east and south of Lake Washington.

• Expanding Sounder south line capacity and service, adding two new stations.

• Improving access and expanding parking at Sounder stations.

TREE REMOVAL AND REPLACEMENT

SUMMER 2018

Starting in early 2019, Sound Transit will begin removing trees in areas where track,

guideway or other transit infrastructure will be located in order to protect safe and

uninterrupted light rail service. Trees could potentially fall onto tracks or disrupt

power service.

Sound Transit is committed to replacing

trees removed during construction based

on replacement requirements in each

jurisdiction. Where feasible, agency crews

will replant short trees under elevated

guideways as depicted in the graphic

above.

Crews will plant additional replacement

trees around the project corridor. The table

below shows the estimated number of

trees slated for removal and the number the

agency will plant as replacements.

Jurisdiction Number of trees to be removed (est.)

Proposed plantings (est.)

Seattle 180 900

Shoreline 550 2,800

Mountlake Terrace 270 950

Lynnwood 350 1,200

WSDOT 3,950 14,550

MITIGATING NOISE

SUMMER 2018

Construction of the guideway requires the removal of some existing Interstate-5

noise walls along the corridor; those will be replaced as needed. Crews will also

place new walls along the guideway at select locations to mitigate noise from light

rail operations and at stations to enhance the patron experience by mitigating noise

from I-5.

Temporary Noise Walls• Temporary removal of existing traffic noise walls during project construction will

be required to make room for work activities and equipment mobilization.

• Crews will replace removed I-5 noise walls with new in-kind walls before the end

of project construction.

• In the interim, the use of temporary noise barriers, where feasible, will provide

partial traffic noise mitigation.

• Specifics regarding locations and duration of temporary noise barriers locations

will be available after the development of a detailed construction plan.

Examples of Sound Curtains

CONSTRUCTION

Selective demolition work Sound Transit has acquired several properties along the corridor.

These properties are needed for construction and transit operation,

and have been brought to Sound Transit’s attention by their neighbors

as potential areas of nuisance now that they are empty. Starting June

2018, we will begin demolishing existing structures and clearing

debris.

Fieldwork This spring, crews have been drilling in the project corridor to locate

utilities and evaluate underground soil conditions for future systems

that support light rail operation. This fieldwork is nearly complete and

helps to pave the way for construction.

Third-party utility relocations Private utility companies, such as electrical, cable and telecoms, will

be moving their infrastructure in advance of construction work in the

area. Contact your utility company if you have any questions about

service interruptions and planned work.

Sound Transit-led utility relocation

Sound Transit will install and relocate utilities in order to remove

infrastructure that may be in the way of upcoming construction, as

well as better align service to the future guideway and stations.

Clearing and grading of vegetationIn advance of construction work, Sound Transit contractors will

remove vegetation to allow space for construction work, equipment

and materials staging, or access to construction areas.

Active construction beginsIn fall 2018, look for specific information about areas of work,

construction sequencing and potential impacts. Major construction

activities are scheduled to begin in mid-2019. At this time, crews

will move large equipment into place, fence in work areas, create

detours around active construction sites.

New bike access to First Avenue Northeast in Seattle Crews will remove bicycle access to First Avenue Northeast from Northeast

115th Street in order to build the new guideway. After construction of the guideway is

complete, the building of a new trail will restore access.

Pedestrian and bicycle access to new Shoreline South/145th Station in Shoreline People who walk or bike to the new Shoreline South/145th Station from the north

will have a new option to access the station. Sound Transit will build a new trail that

will connect Northeast 152nd Street to the north side of the station, running in part

underneath the new guideway.

Ronald Bog improvements The city of Shoreline and Sound Transit propose using an area of Ronald Bog Park for

a wetland mitigation site to replace wetlands affected by light rail construction. Under

the plan, trail enhancements would balance the use of other portions of the park for

wetland mitigation.

McAleer Creek buffered work area The elevated light rail guideway will cross the State Route 104 interchange loop

50-60 feet above the grade of Interstate 5. To support the structure, crews will construct

four columns along the west side of the interchange loop, spaced approximately 120

feet apart. The columns and guideway in this location are within Washington State

Department of Transportation right of way.
