Refinements in Design

• Curb Extensions

 – Safety needs (turning vehicle speeds)

 – Stormwater management opportunities

 – Historic Preservation Stakeholders

• Design of parks/plazas

• Utility locations/needs

• Final lane widths/median dimensions

Process and Approach

• Implement corridor-wide streetscape as

typical capital project using FHWA funds

• Address site-specific locations with interim

treatments

• Design – Bid – Build to resolve detailed design

issues
