This document is a preliminary plan for a Streambank Stabilization Assessment prepared by Freese and Nichols for Lilburn City Park, located in the City of Lilburn. Alternative 3 of the stream restoration project involves comprehensive streambank improvements along Camp Creek, including grading, stabilization, and infrastructure modifications. The project scope includes installing stacked rock wall stabilization along erosional areas, stabilizing exposed soil along the creek's left bank with coir matting and vegetation, installing in-stream structures like rock cross vanes and log vanes, and creating stream engagement areas. The project will also involve removing existing stone structures and potentially constructing a pedestrian bridge and trail.

The site plan details specific engineering interventions across approximately 180 feet of stream, with technical specifications for bank grading, boulder cluster placements, and stream center line adjustments. The project appears to be a municipal infrastructure improvement initiative focused on environmental restoration, erosion control, and recreational enhancement. The preliminary plan includes detailed topographical annotations, proposed grading zones, existing property lines, and a comprehensive legend explaining the proposed structural and landscape modifications. The design emphasizes ecological restoration techniques while maintaining the natural characteristics of the stream corridor.
