The city of Charleston already provides special incentives for high-tech businesses that want to move to the heart of downtown. Now the city plans to extend its "Digital Corridor" to the suburban frontier.

The expansion of the corridor aims to tempt high-tech businesses to the fast-growing Daniel Island/Cainhoy peninsula area, already home to software giant Blackbaud, said Ernest Andrade, the city's assistant economic development director.

The corridor, an initiative designed to bring in high-wage, high-tech jobs, provides several incentives. Benefits, some of which are in place throughout the city, include reduced property taxes and business license fees, a fast-track permitting process, preferred parking in city garages and access to a group health insurance plan.

Andrade said adding parts of Daniel Island and the Cainhoy area could help foster a perception that Charleston is becoming a hot spot for high-tech businesses. About a dozen currently call the city home.

The city is marketing the corridor in other ways, including press releases being sent to national media outlets and on a Web site. The corridor, image-wise, also could be bolstered today with the addition of Cambar Software, which recently moved its headquarters from North Charleston to Cainhoy. City Council will consider a request to annex the company's campus, now under construction just off Clements Ferry Road.
