About Us

Transportation Development

Charleston County Transportation Development Department staff is most concerned with serving the citizens of Charleston County and those who travel our roadways each day. Our commitment to promote and protect the quality of life in Charleston County by delivering services of value to the community is at the heart of everything we do. Our licensed professional engineers and staff work diligently as stewards of the transportation sales tax funding bestowed upon the County by her citizens, and are consistently seeking cost effective solutions to the County's transportation needs.

Many of our staff members are Charleston County residents themselves and call Charleston home and because of this we are keenly aware of the important responsibility we hold to improving community relations and reducing the impact of your commute and daily travels.

We do this by taking a proactive approach to regularly inform our citizens of the progress and work we do by hosting public informational meetings, creating and maintaining an informative interactive website, publishing frequent press releases with traffic and construction updates and encouraging public questions, comments, and suggestions. In this Charleston County Transportation Development Department has been able to build lasting relationships within the community amongst those we proudly serve and call our neighbors, family and friends.

Our Mission: Transportation Development provides consolidated services for construction management, quality control, design and materials testing on multi-jurisdictional infrastructure projects that span federal, state, county and municipal roads, streets, bridges, sidewalks and other transportation-related projects to ensure that funding is expended in an economical and efficient manner.


On May 21, 2013, Transportation Development was one of three Charleston County Government departments to receive the APWA full accreditation award. Charleston County is the eighty-third agency in North America to receive the award. The purpose of the accreditation program is to provide a means of formally verifying and recognizing public works agencies for compliance with the recommended practices set forth in the Public Works Management Practices Manual. It is a voluntary, self-motivated approach to objectively evaluate, verify, and recognize compliance with the recommended management practices.

The objectives of the accreditation program are to:

  • create impetus for organization self-improvement and stimulate general raising of standards
  • offer a voluntary evaluation and education program rather than government regulated activity
  • recognize good performance and provide motivation to maintain and improve performance
  • improve public works performance and the provision of services
  • increase professionalism
  • instill pride among agency staff, elected officials and the local community

The Transportation Development Department conducted a self- assessment of the entire department to determine how the agency's policies, procedures and practices compared to the recommended practices identified by nationally recognized experts in the field of public works. These practices were used as a model to improve existing practices to enhance performance, increase productivity, and to strengthen employee morale.

The next accreditation process will be in May 2017.

The beginning:

In the fall of 2004, Charleston County voters agreed to add a half-cent sales tax on purchases made in the county for 25 years or a total investment of $1.3 billion (click here to download the ordinance). The sales tax will be spent on two priorities - green space acquisition and transportation projects including mass transit. Collections of sales tax funds began in May of 2005.

Voters passed a second bond referendum in November, 2006, which approved an additional issuance of up to $205 million that may be used on additional roadway projects (click here to download the referendum).
