The Cedars East Storm Drainage Improvement project consists of a 300+ acre watershed located in southeast Charlotte, North Carolina, near Idlewild Road. Charlotte-Mecklenburg Storm Water Services (CMSWS) identified this area for study and improvements to the storm drainage infrastructure due to failing infrastructure and residential structure flooding reports. CMSWS partnered with STV Engineers, Inc. to complete the planning study, design, public outreach, utility coordination, and construction administration services. Drainage improvements within the project area include reinforced concrete box culverts ranging in size from dual 8-foot by 4-foot to 12-foot by 8-foot totaling more than 1,300 feet in length and natural stream enhancement techniques. Due to the space constraints, an extensive shoring plan was developed to protect existing infrastructure. The design reduced impacts to vital existing utilities to reduce relocation costs and disruption of services to the residents in the neighborhood.
