Owner Objective

The Keowee-Toxaway State Park is located on 1,000 acres in Pickens County, South Carolina, on Lake Keowee. CEC was retained by Duke Energy (Duke) for design, permitting, and construction related services in support of upgrades to the Park owned and operated by South Carolina Department of Parks, Recreation and Tourism (SCPRT). The Project, named Camp Cedar Creek at Keowee-Toxaway State Park, included approximately 5,000 linear feet of access road, multiple parking facilities including kayak off-loading zones, a campground, restroom and bathhouse facilities, cabins, picnic shelters, fishing pier and utility connections in the 16-acre project area.

CEC Approach

The site design, incorporated stormwater quality treatment measures including stormwater inlet filters and lake and stream buffers. The roadway widening improvements required the replacement of an existing undersized roadway culvert. The culvert replacement and fishing pier design included 404/401permitting with the USACE, SCDHEC and SCDNR.

Due to the rugged topography and grading activities occurring in close proximity to Lake Keowee, extensive erosion control measures were designed and permitted through Pickens County and SCDHEC.

Camp Cedar Creek was completed and opened to the public in 2019.
