This project consists of multiple isolated storm drainage improvements projects located throughout the City of Charlotte. Projects include storm drainage improvements and replacement and repair of existing storm drainage system facilities within the street right-of-way and private, residential properties.
Collective Storm Drainage Improvement Project Series Z will be comprised of two separate projects, 1818 Baxter Street and 7316 Thorncliff Drive. 1818 Baxter Street’s main component will include 46 linear feet of 9’x6’ precast reinforced concrete box culvert with sills. 7316 Thorncliff Drive’s main component is 213 linear feet of 6’x7’ precast reinforced concrete box culvert with sills. 7316 Thorncliff Drive will also include storm drainage improvements in the road way with approximately 300 linear feet of 18” to 30” reinforced concrete pipe, and several utility relocations.
This project is bordered by Laurel Avenue to the north, Dotger Avenue to the south, Randolph Road to the east and Hempstead Place to the west. The existing drainage system consists of closed pipe systems. This drainage system is currently undersized and street flooding has been reported on Colville Road and building flooding has been reported on Cranbrook Lane.
This project is bordered by Rama Road to the north, McAlpine Creek to the south, Monroe Road to the east and Burlwood Road to the west. The drainage system consists of open channel and closed pipe systems underneath City maintained roads. This was previously identified as a major capital project from the watershed ranking prioritization process with a score of 54 of 100. The ranking protocol identifies 30 structures that experience flooding in the 100-year storm event and 16 roads that experience transverse overtopping events that do not meet current standards. A holistic project is needed to cost beneficially address the drainage system issues.
Update: This project will no longer be standalone and will become part of Collective AC SDIP.
This project is located along Fairway Ridge Road bordered by 4 Mile Creek Rd and Ballantyne Commons Pkwy. The existing drainage system consists of the culvert and closed pipe system under city-maintained roads. The drainage system is in poor condition and flooding has been reported.
This project is bordered by Highway I-85 to the north, Cinderella Road to the south, Echo Glen Road to the east, and West Sugar Creek Road to the west. The drainage system consists of open channel and closed pipe systems underneath city-maintained roads. This was previously identified as a major capital project from the watershed ranking prioritization process, scoring 73 of 100. The ranking protocol identifies 18 structures that experience flooding in the 100-year storm event and 7 roads that experience transverse overtopping events that do not meet current standards. The entire neighborhood has received a patchwork of repairs over the years and a holistic project is needed to cost beneficially address the drainage system issues.
