Huger Street and King Street Drainage Improvements

The intersection of Huger Street and King Street has been subjected to flooding following major rainfall events for years. This flooding has prevented passage of vehicular traffic and has caused significant property damage in the past. During major rain events, parts of the intersection have experienced flood inundation depths near 2-3 feet.

In October 2018, Johnson, Mirmiran & Thompson (JMT) completed and submitted a drainage basin study to the City addressing the current challenges and recommendations on how to improve the drainage in and around the Huger Street and King Street intersection, including upsizing portions of the conveyance system and installing a pump station to manage the run-off of major rainfalls.

From the October 2018 study, the City is moving forward with implementing drainage improvements to the basin including increasing storage in the area, upsizing select existing conveyance systems, and building a pump station to handle flow from significant storm events. The work will be conducted in two phases: Phase 1 improvements are in preparation for the pump station that will be installed during Phase 2. 

Phase 1 construction lasted from 2021-2022.


Phase 2 of the project included the installation of a pump station and outfall system to move water from the intersection and out into the open waterways near the project. The design of this phase is curently underway. Construction is expected to start by 2024 and will complete by 2025.

When completed, this drainage basin will have more capacity and discharge of up to 70,000 gallons of floodwaters per minute to significantly reduce the intersection's flooding. 

The City was recently awarded $10 million in funding from the South Carolina Infrastructure and Economic Development Fund for the King-Huger project to help complete the second and final phase of the project.
