New station would be built across Damen Avenue, below the existing tracks.] Slide 25 Damen – Scheme B1 New Station Location [2 photos of area immediately across Damen from current station.] Slide 26 Scheme B1 New Station Elevator Location (Outbound) [Photo across Damen from existing station.

Significant impact on historical station house. OUtboudn stairs impacted. Adjacent historical properties – impact TBD. Transfer bridge – yes. New southeast exit stairs on both sides. No impact on alley access. Scheme A2: 2 elevators (both to street level). Significant impacts on historic station house; for example, a new enclosed walkway to one of the elevators. Adjacent historical properties – impact TBD. Transfer bridge – No. New southeast exit stairs on both sides. No impact on alley access. Schemes B1 and B2 – note that existing operations can be maintained during construction because these schemes involve building a new station house across Damen Avenue from the existing historic one. Scheme B1: 2 elevators (one to street level). The existing station would become a secondary exit. Adjacent historical properties – impact TBD. Transfer bridge – yes. New southeast exit stairs on both sides. A bridge would be built over the alley next to the new station. Scheme B2: 2 elevators (both to street level). The existing station would become a secondary exit. Adjacent historical properties – impact TBD. Transfer bridge – No. New southeast exit stairs on both sides. The alley would become dead ended.
