3.16 PROJECT OVERVIEW

SUMNER STATION ACCESS IMPROVEMENTS PROJECT

• Access improvements to Sumner Station were approved by voters in 2008 as part of the Sound Transit 2 ballot measure to expand mass transit throughout the region. • In August 2014, the Sound Transit Board identified a preferred package of access improvements at Sumner Station for environmental review and preliminary design. • The improvements include a parking garage and an additional surface lot at the station and pedestrian and bicycle improvements. • Improving easy and reliable access to the station will be necessary as ridership and service increases. • Average daily ridership on the south Sounder line is expected to increase by more than 13,000 by 2035.

• Proposed 4 1/2 story parking garage at the existing surface parking lot would provide a net increase of 505 parking spaces

3.16 HOW WILL THE PROJECT IMPROVE STATION ACCESS FOR PEDESTRIANS AND BICYCLISTS? SUMNER STATION ACCESS IMPROVEMENTS PROJECT

Sound Transit is working with city staff to identify improvements that will make it easier for people who walk and bike to the station. Sound Transit is also evaluating an optional pedestrian bridge over the railroad tracks.

Potential improvements • New or improved • Signal improvements crosswalks • New bike storage • Sidewalk improvements • Curb ramps

Examples of a pedestrian crossing

3.16 WHAT IS A SEPA CHECKLIST?

SUMNER STATION ACCESS IMPROVEMENTS PROJECT

A State Environmental Policy Act (SEPA) checklist is an environmental evaluation that studies potential impacts and benefits of a project.

The following categories were studied*: • Aesthetics • Air • Animals – includes Endangered Species Act • Coordination with local transit • Earth • Energy and natural resources • Environmental health – includes hazardous materials and noise • Historic and cultural preservation • Housing • Land and shoreline use • Light and glare • Plants • Public services • Recreation • Transportation • Utilities • Water

* The project also complied with National Environmental Policy Act (NEPA) evaluation requirements. 3.16 WHAT IS A MITIGATED DETERMINATION OF NON-SIGNIFICANCE?

SUMNER STATION ACCESS IMPROVEMENTS PROJECT

A Mitigated Determination of Non-significance (MDNS) means that the proposal is unlikely to have significant adverse environmental impact with mitigation measures incorporated as part of the project. Some of the environmental study highlights include the following: • Aesthetics - The project would be consistent with the City of Sumner’s Design and Development Guidelines for the parking garage. Stakeholder and citizen input in regards to the exterior facade will be incorporated as the design progresses. The exterior facade and landscape design would be aesthetically pleasing, functional and work within the context of its surroundings. • Noise - Potential noise levels from the proposed project and its construction were evaluated. Noise mitigation was considered and found not to be necessary because the existing noise levels are higher than the predicted noise from the parking garage. • Transportation - The evaluation concluded that no localized mitigation measures would improve the affected intersections due to the current congestion caused by the SR 410 interchange at Traffic Avenue. Therefore, the proposed approach to addressing these intersections is to coordinate with the City on sequencing the Sumner parking garage and SR 410/Traffic Avenue improvements.

3.16 SR 410 INTERCHANGE IMPROVEMENTS

SUMNER STATION ACCESS IMPROVEMENTS PROJECT

Sound Transit is participating in a partnership with WSDOT and the Cities of Sumner and Puyallup to develop the design for the SR 410 interchange improvements and obtain the funding to construct them. As part of the Sumner Station Access Improvements Project, Sound Transit would contribute financial support to the SR 410/Traffic Avenue interchange improvements, which would improve access for people walking, biking, taking the bus and driving to the station.

3.16 HOW TO STAY INVOLVED

SUMNER STATION ACCESS IMPROVEMENTS PROJECT

In spring 2016, Sound Transit will select a project to be built. The project will enter preliminary engineering, then final design. Between now and construction, Sound Transit will: • Continue developing station design Stay tuned for future • Identify architectural elements opportunities in 2016 • Finalize non-motorized improvements to provide design input.

• Continue partnering with City of Sumner staff Sign up for project email updates at: soundtransit.org/subscribe • Coordinate with private property owners

• Conduct field work

• Coordinate permits

• Define the construction schedule and methods
