Reasonable Alternative Concepts

In accordance with the National Environmental Policy Act (NEPA), Charleston County focused on minimizing social, economic, and environmental impacts and reaching national, state, and local environmental protection goals, while providing safe and efficient transportation. Thorough traffic analysis and public feedback helped narrow eight possible alternatives down to three reasonable ones. The three remaining reasonable alternatives continued through the NEPA process, where the Project Team studied their impacts to wetlands, streams, existing communities, protected species, noise, traffic, cost, and more for each option.
