Sumner Sounder Station Acess Improvements Environmental Reports State Environmental Policy Act (SEPA) Checklist

Sound Transit (ST) has prepared a State Environmental Policy Act (SEPA) Checklist along with Technical Reports and issued a Mitigated Determination of Nonsignificance (MDNS)under SEPA Rules (Chapter 197-11 WAC) for the Sumner Station Access Improvements Project. The project would enhance the access to Sumner’s Sounder Station, by constructing a parking garage along with non-motorized improvements in the City of Sumner, Pierce County, Washington. The project includes a new 4 1/2 story parking garage with approximately 623 parking stalls. On completion of the project, the total number of parking spaces would be 857, which is an increase of 505 parking spaces over the existing number of 352. Exit from the new parking garage would be restricted to right turn onto Thompson St from Station Lane. The project also includes access and non-motorized improvements, such as driveway replacements, sidewalks, bicycle storage in the parking garage, curb ramps, pedestrian signal, and an optional pedestrian bridge over the railroad. Based on the Checklist, Sound Transit has determined that this proposal will not have a probable significant adverse impact on the environment .
