Arizona-based artist Mary Lucking is working on a series of murals and cut metal screens populated with images of imagined birds and plants. She thinks of the birds as stand-ins for the station’s neighbors and writes “in some places, the birds are

Detail of mosaic fabrication technique. Concept sketch showing cut metal bird and plant forms on north entrance building.

Lucking’s inspiration comes from a variety of sources, including her exploration of local neighborhoods set amid tall trees, the forests of folktales and the notion of nests as a metaphor for home.

Sound Transit Art ProgramMountlake Terrace Station Artist: Kipp Kobayashi

ABOUT THE ARTIST As an artist and urban designer, Kipp Kobayashi has a keen interest in the nature of human interaction in our public environments and is in constant search for ways to initiate dialogue and to promote sociability within these spaces. His

combinations that are unique to each project. By focusing on these intersections of the human, cultural and natural factors, he aims to create artwork that can continue to change, grow and evolve along with the world around it; forever changing how we perceive a particular place or thing.

At the entrance to a multi story mixed-use project in Pasadena, Kobayashi chose to explore different types of social connectivity abstractly through a project winding up through an outdoor courtyard.

In 2016, Kobayashi was invited to create 6 unique street crossings as part of the Southern California Vision Zero street safety improvements. The initial process involved the tracing of the actual movement of people as they crossed the street.

The artwork also refers to natural systems of migration and

breakwater, serving as an analogy to the rejuvenation of this redeveloping downtown area.

project in Southern California. Here, Kobayashi photographed local skaters, turning those images into silhouettes.

Rendered life-size onto the park’s surfaces, the silhouettes create the impression that the entire deck is like the surface of a pool of water full of blue rippling waves.

Containing the layers of stories that ultimately form each company’s unique identity, the objects and tools collected by

hallways provided inspiration for this suspended sculptural composition.

Over 200 scanned and printed objects were arranged in sequential strands. Reminiscent of hoses hanging within traditional drying towers, they serve as an archive of past events while implying multiple combinations of narratives in a lyrical and playful way.

EXAMPLES OF THE ARTIST’S PAST WORK

Imagining what future activities and dialogue might occur here, hundreds of folded “aerogami” shapes were envisioned swirling whimsically above the plaza.

Below are types of noise mitigation that Sound Transit can use to help reduce noise along Link light rail alignments.

Elevated sound walls• Installed close to the track

• Made of stainless steel or aluminum

• Inside surface absorbs sound

• Wall heights range from four feet to 10 feet over the elevated deck

• Provide noise reduction up to 15 decibels

• Audible emergency messages at platform

Elevated sound barriers• Thick plastic/rubber sheets used on elevated guideway

• Used when less than 10 decibels noise reduction is needed

At-grade sound walls• Typical sound walls seen along freeways

• Made of concrete or engineered composites

• Wall heights can range from eight feet to 26 feet

• Provide noise reduction up to 15 decibels

UNDERSTANDING NOISE WALLS AND NOISE MITIGATION

TREE MITIGATION

Trees removed for construction and future operationsConstruction of the guideway and stations requires removal of trees along the corridor. Trees will be planted to mitigate those being removed. Sound Transit continues to work with local jurisdictions to maximize planting opportunities and will plant more trees than those being affected.

Tree placement strategiesSound Transit continues to work with local jurisdictions to determine where new trees will be planted. Plans may include strategic replacement plantings and community engagement opportunities. The Roadside Master Plan also outlines the future restoration and vegetation landscaping along Interstate 5 where light rail will be constructed.

TREE SAFETY ASSESSMENT

Primary clearing and grading limits All trees and vegetation in this area are removed for construction access and guideway operations.

LEGEND

Secondary clearing and grading limitsTrees that could fall into the primary area are removed. Branches that reach into the primary area are pruned. Vegetation and trees could be removed for construction or guideway access.

Peripheral limits Trees and vegetation are monitored for potential future safety risks and are pruned accordingly.

Maintaining a clear area around the Link light rail guideway ensures a safe and reliable space for trains to travel. Removing trees and vegetation minimizes the chance for branches to fall onto the tracks and disrupt service.

Area of wetland impacts

Wetland impacts are mitigated through reestablishment of wetlands at Ronald Bog Park.

The Lynnwood Link Extension project will permanently impact approximately 0.42 acres of wetlands along I-5 in the City of Shoreline. Sound Transit will mitigate these impacts by reestablishing approximately one acre of wetlands at Ronald Bog Park, which will increase ecological functions and values. Outside of the wetland mitigation areas, new and improved trails will enhance pedestrian access.
