Charlotte-Mecklenburg Storm Water Services is requesting proposals from qualified companies interested in providing Professional Engineering Services for Various Storm Water Services Projects. The selected firms will use HEC-HMS, HEC-RAS, SWMM, and/or a hydraulic grade line closed system computer model, or an approved alternative method. All methods will be in accordance with the Charlotte-Mecklenburg Storm Water Design Manual. The City’s then current AutoCAD standards will be used for production of all plans and profiles. The selected company(ies) may be required to pursue stream restoration and enhancement for mitigation credit in accordance with NCDEQ and USACE requirements, where appropriate.
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.
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.
This project consists of 400 LF of existing 24” RCP along 6th St, from N Church St to N Popular St, will be rehabilitated through pipe bursting methods. Two work pits will be excavated, one at the corner of 6th & N Church St, and the other at 6th & N Popular St. The project will require road closures at 6th & N Church St and 6th & N Popular St, and 1 lane closure along 6th street. A new stormwater junction box will be installed at the corner of 6th street and N Popular St.
This project is bordered by Speer Boulevard, West Tyvola Road, and Yorkmont Road. The drainage system is open channel that was a previously stream restoration project. This project will repair one of the previously restored channel reaches.
Work performed under this contract will consist of storm water infrastructure repair and improvement projects within the city limits of Charlotte, NC. Work will involve mobilization, earthwork, drainage structures, storm drain pipe systems, channels, working over, under, near, and around existing private utilities, asphalt paving, concrete flatwork, and landscaping and any associated work required by the Engineer. Other work may include structural foundation protection, storm water pipe lining, storm water pipe joint and structure repair, water, and sewer (relocations, installations and adjustments). Storm Water maintenance work may be located entirely within or a combination of the street right-of-way, private, residential, and commercial properties.
