| 摘要： | The National Park Service proposes to repair and stabilize Connecting Avenue to provide a sustainable solution that would prevent further erosion of Fort Hill within the Vicksburg National Military Park in Vicksburg, Mississippi. This Environmental Assessment analyzes the potential impacts of two alternatives (a No-Action Alternative and one action alternative) on the human environment in accordance with the National Environmental Policy Act of 1969. Under the No-Action Alternative, the slumping of Fort Hill from erosion would continue causing Connecting Avenue to continue to buckle. For the action alternative, the NPS would correct the slumping of Fort Hill by installing a shear key buttress, 200 feet below and roughly parallel to Connecting Avenue. A base drain would be installed in the area of the buttress, and it would outlet at both ends of the buttress. The existing asphalt and aggregate base along Connecting Avenue would be removed and replaced in kind, and a curb and gutter system would be installed. |
