Surface Water Quality Projects Support

The City has collected water quality data throughout the City limits and ETJ and developed 22 sub-watershed data matrices. Watershed modeling is nearly complete for one watershed, and watershed planning efforts are currently underway for two watersheds. The contracted firm will aid and support current and future watershed modeling and planning efforts.

The awarded firm will provide services for several pond and dam rehabilitation/stormwater control measures (SCM) projects. This will include initial feasibility studies, planning and design for projects that are not specified at this time. Additional tasks will include the evaluation and repair design of existing municipal SCM projects. These projects are anticipated to start scoping upon contract award. 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.
