2 ROJECT OVERVIEW SUMNER STATION ACCESS IMROVEMENTS ROJECT 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 KEY Existing station area Washington St 167 Existing parking roposed garage roposed surface parking Optional pedestrian bridge Not shown: additional non-motorized improvements Bridge St Fryar Ave Wood Ave Existing parking (68 stalls) Main St Existing leased parking (50 stalls) Maple St Sumner Station State St Hunt Ave E Main Ave Traffic Ave 410 Harrison St Cherry Ave New garage and reconfigured surface lot (505 stalls) Thompson St Alder Ave ark St Sumner Ave Academy St Existing Bonney Lake ark and Ride (356 stalls) 5 miles N

3 HOW WILL THE ROJECT IMROVE STATION ACCESS FOR DRIVERS? SUMNER STATION ACCESS IMROVEMENTS ROJECT roposed 4 1/2 story parking garage at the existing surface parking lot would provide a net increase of 505 parking spaces Before Conceptual After - Conceptual drawing (for discussion only)

4 HOW WILL THE ROJECT IMROVE STATION ACCESS FOR EDESTRIANS AND BICYCLISTS? SUMNER STATION ACCESS IMROVEMENTS ROJECT 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. otential improvements New or improved crosswalks Signal improvements New bike storage Sidewalk improvements Curb ramps Examples of a pedestrian crossing

5 WHAT IS A SEA CHECKLIST? SUMNER STATION ACCESS IMROVEMENTS ROJECT A State Environmental olicy Act (SEA) 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 lants ublic services Recreation Transportation Utilities Water * The project also complied with National Environmental olicy Act (NEA) evaluation requirements.

6 WHAT IS A MITIGATED DETERMINATION OF NON-SIGNIFICANCE? SUMNER STATION ACCESS IMROVEMENTS ROJECT 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 - otential 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.

7 SR 410 INTERCHANGE IMROVEMENTS SUMNER STATION ACCESS IMROVEMENTS ROJECT Sound Transit is participating in a partnership with WSDOT and the Cities of Sumner and uyallup 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 roject, 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.

10 HOW TO STAY INVOLVED SUMNER STATION ACCESS IMROVEMENTS ROJECT 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 Identify architectural elements Finalize non-motorized improvements Stay tuned for future opportunities in 2016 to provide design input.
