SR 522 / NE 145th BRT Phase 2David Evans & Associates scope of work: Conceptual Design

• Fieldwork, data collection and technical studies • Stakeholder involvement • Roadway, station area, and parking facilities designed to 10 percent

Environmental Review with SEPA Checklist• Expanded checklist process• Stakeholder involvement and sufficiency for cities’ SEPA needs

1111

• Using consistent methodology: 2018$; construction, real estate, etc.

• Based on limited design (1-2%): 2018$; updated construction figures, updated real estate, etc.

• Estimates do not establish project budget: Project budget established during final design
