Project Overview:
Civil Construction Charlotte: Repair failed stormwater retention pond.
Project Description:
Repair earthen embankment for failed stormwater retention pond at an educational institution. Carolina Civil had to clear the existing pond of all organic materials, mud, and muck from the bottom. We also imported, placed and compacted particular soils, meeting project specifications, to restore the failed pond dam.
Carolina Civil’s team repaired existing utilities restoring them to proper function. Once the earthwork and utility operations were completed, final grading and stabilization operations began. We installed a new rip rap overflow spillway, and the site was planted with grasses to meet the stabilization needs.
Project Challenges:
The failed retention system was the final collection point for the campus’s storm water system. Failure to remediate the pond posed enormous liabilities. Without a properly functioning earthen embankment, storm water, collected throughout the campus, would pass through the system indirectly into the wooded area and streams on the adjacent property. Without retaining the storm water and allowing sediment to settle, sediment-laden storm water would impact other properties and potential wetland areas by flowing uncontrolled.
Excavating and placing material in such environmentally and sensitive weather conditions remained at the forefront of everyone’s focus. Excavators, trucks, and bulldozers were utilized to remove the muck from the basin. In a highly-coordinated effort, trucks carrying earthen materials were chartered through the campus in a one way in, one way out fashion. The weather was a focus as torrential rains showers would flood the work area. Engine driven water pumps were utilized to control the water levels in the basin, allowing work to proceed.
Project Highlights:
Carolina Civil completed the project and restored the storm water retention system to a functioning capacity. Storm water runoff was controlled during construction without impacting adjacent properties or the environment. The project was safely delivered, on time and on budget, meeting the client’s expectations and satisfaction.
