Transportation Improvement Program (TIP)

The Transportation Improvement Program (TIP) is a rolling 6-year plan updated annually with a focus on maintaining the existing transportation network and improving it in a thoughtful, safe manner working within the financial constraints of the Street Fund and other funding sources. The TIP covers City roadway, pedestrian, bicycle and other transportation projects.

State law requires that the TIP be updated and adopted by elected officials annually. The City Council typically adopts the TIP each spring after public comment.

The 2025-2030 TIP was adopted by the City Council at the June 18th, 2024 City Council meeting. The final version of the TIP documents can be found in the supporting documents below.
