The following is a general description of the Scopes of Service included in this RFQ. The selected firms will use HEC-HMS, HEC-RAS, and/or a hydraulic grade line closed system computer model, or an approved alternative (SWMM) 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.
Work will be issued via written Task Orders, which will specify the requirements of the various projects. Multiple Task Orders may be issued for each project. Multiple Task Orders may be issued at once. The City of Charlotte reserves the right, upon successful completion of a given Task Order, to issue subsequent Task Orders to the same or a different Company.
The below list provides a general list of the tasks required. Task orders may include any of the following:
- Surveying, utility locating, and PACP stormwater asset inspections.
- Existing and Proposed Conditions Analyses
- Channel Stabilization and/or Restoration
- Utility Coordination
- Easement/Plat Preparation
- Public Engagement
- Preliminary and final design
- Permitting/Encroachments
(404/401, NCDOT, Railroad Agencies and FEMA Floodplain Development Permitting)
- Preparation of Construction Documents (Plans, Specifications, and Cost Estimates)
- Bid and Construction Phase Services
- Geotechnical and Structural Engineering Services
The city anticipates selecting multiple firms to provide these services. These will be drainage area-based storm drainage improvement projects that involve differing land uses within the project areas. Drainage basins may include closed and open systems. The study areas may be on a portion of the watershed or the entire watershed. Task orders may be issued for multiple projects at once. Upon satisfactorily completing a task order, the City may issue additional task orders. Scoping on these projects is anticipated to begin in early 2026.
There is an existing wetlands system and stream adjacent to the Bruns Academy that are in need of improvements. The intent of this project is to reset an existing wetlands system to its original design and provide enhancement, where applicable. Wetland restoration efforts will include regrading, sodding and planting of vegetation, installation of a new pedestrian bridge and retaining wall. Additionally, stream improvements, such as regrading banks and adding riffles, are proposed. The proposed improvements will enhance the overall performance of the system for conveying and treating stormwater.
The Hastings/Princeton Storm Drainage Improvement Project will reduce street and structure flooding throughout the neighborhood. Located within a drainage area of approximately 80 acres, the project will replace aging infrastructure and provide adequate system capacity. The project area is bordered by Wellesley Avenue to the north, Hastings Drive to the south, Selwyn Avenue to the east and Jamestown Drive to the west.
Old Plank portion of project: Project initiated due to failure of 84” CMP system on Old Plank Rd. City plans to remove and replace 86” CMP with 56LF 8’x7’ RCBC; Add (2) concrete wingwalls;
Caldwell Williams portion of project: Project initiated due to road flooding. City plans to replace (2) 60” CMP pipes with 39 LF of 13×5 Box culvert. City also intends to add 40LF of 18” RCP; (2) Double catch basins and (2) concrete wingwalls; Pavement and curb replacement.
Project initiated to permanently fix what was an old AFT project. City intends to replace the existing 12’x8’ CMP and replace with approx. 50 LF of 10×8 RCBC; Add (2) concrete wingwalls; (4) CBs; (1) JB; Asphalt and curb replacement; Tie existing sewer crossing into a separate system (2) SSMH’s and approx 30 LF of 8” DIP; 15 LF 15” PVC
The project is bounded by Pondella Drive to the West and North, Georgetown Drive to the South and Rosada Ave to the East. The project involves storm drainage improvements along Georgetown Rd primarily with some improvements in intersections with Rosada Avenue and Pondella Drive.
The project is bounded by the Park Rd Shopping Center to the South, Park Rd to the West, Arbor Lane to the North and Little Sugar Creek to the East. The project involves storm drainage improvements along Reece Rd primarily with some improvements in intersections with Park Rd and Arbor Lane.
Project consists of removing a gabion wall and replacing it with a new segmental block wall. Minimal stream impacts will be made only to install wall. Partial storm system in ROW will be removed and replaced with no outfall impacts.
This project involves installing a closed drainage system down both Briargrove Dr. and Milton Rd. to reroute runoff from an existing stream. The proposed closed drainage system ties back into the existing culvert under Colby Pl.
