SUMMARY


A Charleston, South Carolina government authority is seeking engineering support for conceptual drainage channel and infrastructure improvements. The work includes site assessment, surveying, hydrologic and hydraulic modeling, regulatory coordination, and review of property and easement considerations.

DESCRIPTION


The government authority in Charleston, South Carolina, seeks professional engineering services for improvements to a central drainage channel and associated drainage infrastructure. The project will evaluate varying design storm and tidal conditions while seeking to avoid adverse upstream or downstream impacts and account for environmental considerations, property and easement requirements, constructability, and cost.

Services are expected to include a preliminary assessment of existing site conditions, limited topographic surveying, and selected field investigations needed to evaluate conceptual alternatives. The selected provider will review available studies, GIS data, stormwater inventories, existing models, survey information, and other relevant materials; perform conceptual-level hydrologic and hydraulic modeling of existing and proposed conditions; assess potential regulatory and permitting issues; coordinate with applicable utilities and regulatory agencies as needed; and review property and easement information to identify potential real estate considerations.

The contract period will be one year.
