Learn Why It Matters

Developed Through Public Input

Charleston County developed the proposed Transportation Sales Tax Program through a broad-based public, municipal and stakeholder engagement process designed to identify transportation priorities across the county.

As part of that effort, County staff attended and presented at nearly 80 public and stakeholder meetings across Charleston County. This outreach resulted in approximately 29,000 public comments, more than 600 individual project requests and approximately $68 billion in identified transportation needs.

On January 13, 2026, staff presented the full public input report to County Council. The report documented the transportation, transit, greenspace and infrastructure needs identified through public engagement and helped inform the next phase of program development.

Using this public input, County Council adopted a set of guiding principles to help shape the proposed Transportation Sales Tax Program and directed staff to develop the program that the public will be asked to consider on November 3, 2026.
