Downtown Project

The Downtown Project will focus on upgrading the infrastructure - below and above ground - and improve the overall flow and safety of car, bike, and pedestrian travel in the downtown area.

Public Engagement: The development of the project will include a significant public outreach and engagement process to help determine the scope of the project. This includes the participation of a Design Advisory Committee. Community members will have opportunities to participate in a public engagement process, through stakeholder meetings, public workshops, and City Council Meetings. Throughout the engagement process, design engineers will develop conceptual plans that consider stakeholder feedback.

Phase I & II: 

Completed in 2022 and included pavement repair, upgraded ADA curb ramps, rehabilitated sewer and storm drain system along West Blithedale, Gardner, Corte Madera, Sunnyside and Throckmorton.

Phase III: 

This phase was completed in summer 2023 and focused on the Downtown paving and curb ramp improvements located along Throckmorton and Miller.  These curb ramps were upgraded to meet current ADA standards.
