## Description

The purpose of this project is to provide Architecture and Engineering (A&E) Pre-Design (PD) and Schematic Design (SD) services that entail the rehabilitation of four CCC-era retaining walls at the boarding/disembarking areas at the Green River Ferry Crossing. These walls are structural elements that hold the riverbank and roadway in place for the only vehicle access to the ferry landing. If these walls fail due to continued degradation or a major flood event, the ferry boarding/disembarking locations will slump into the riverbank, rendering the Green River Ferry unusable at Mammoth Cave National Park Mammoth Cave, Kentucky.
