Spring Park Drainage Improvements

Severe bank erosion along the stream at Spring Park in Winston-Salem, North Carolina, was threatening the integrity of the roadway along West End Boulevard. Storm drainage infrastructure upstream of the park collapsed, causing a large sinkhole and flooding conditions during storms. A section of streambank experienced a catastrophic shear failure during a storm in 2015.

Construction documents were prepared to provide slope stabilization, stream restoration, and drainage and roadway improvements. Before being acquired by LJB Inc., the JEWELL Engineering Consultants team contracted with Kris Bass Engineering for design of the stream improvements, which was based on natural channel design techniques to stabilize streambanks and reduce stormwater velocity in lieu of traditional engineering techniques, such as rip-rap, gabion baskets and retaining walls. JEWELL designed the storm drainage infrastructure, replacing undersized and degraded pipes upstream of the tributary and adding infrastructure along West End Boulevard. In addition to infrastructure design, JEWELL provided overall project management and submittals for regulator agency permitting and approvals, and JEWELL assisted the City in the bidding process. The City added additional scope and budget for JEWELL to provide construction management and full-time construction oversight as well.

This project included restoring approximately 550 linear feet of stream, installing 798 linear feet of pipe and 15 structures, and transportation improvements to West End Boulevard that have improved drainage and public safety. Water Quality Certification and Army Corps permits were obtained, and the City acquired the necessary easements. Construction was completed in the summer of 2018.
