With Gwinnett’s population north of 800,000, it is hard to imagine that, years ago, the number of people calling the county home hovered around 100,000. Today, it’s the second largest county in the state.

Although overall population growth is down significantly, Gwinnett still accounted for one-third of metro Atlanta’s population growth this past year. Some point to these numbers as proof positive that Gwinnett’s resources have been, and continue to be, strong assets. Others see those growth statistics as the root of some of the county’s most significant challenges.

Both are correct.

Those interested in the county’s future can find out more at the third annual Gwinnett Redevelopment Forum from 8 a.m. to 1:30 p.m. Friday at Atlanta Marriott Gwinnett Place. The event — hosted by the Gwinnett Chamber, Council for Quality Growth and the Congress for New Urbanism — will outline why the county is the place for new investment, development and business. It also will include segments on real estate success stories throughout the southern United States. Christopher Leinberger of the Brookings Institution is keynote speaker.

Gwinnett is now considered a “mature community.” Sustainable redevelopment has become the focus. County officials and leaders are moving toward urban solutions to urban issues: traffic congestion, crime, and aged or vacant developments. The resolve and resources exist for solutions, with strong partnerships among the county, cities, community improvement districts and businesses.

Five years ago, the Gwinnett Chamber of Commerce launched its Partnership Gwinnett initiative. Officials recognized these urban issues and provided a framework for results-oriented tasks.

Gwinnett’s cities, its heartbeat, are investing in their downtowns, strengthening their character and offering a sense of place. One example: Norcross, which converted land adjacent to its historic downtown into a large urban open space that’s now a year-round focal point.

The Gwinnett County Board of Commissioners also has recognized the need for change. Officials are overhauling zoning ordinances and regulations that have not been significantly modified in more than 25 years.

The best example of adapting to a rapidly shifting demographic setting can be found in Gwinnett’s public schools. The system is a recent recipient of the Broad Prize, which recognizes the nation’s best school system in an urban setting.

Community Improvement Districts and the business community recently outlined their desire for transit alternatives, securing funds for an exhaustive study of the I-85 corridor. This initiative is critical to the community’s long-term success and sustainability.

Have we addressed all issues? No. I am encouraged by the fact that officials, residents and businesses are coming together to seek initiatives that continue to make Gwinnett a great place to invest.

Chuck Warbington is executive director of the Gwinnett Village Community Improvement District.
