Hitchcock Woods Stormwater Management Project – Aiken, SC

Project Details
Hitchcock Woods, located in the heart of Aiken, South Carolina, is one of the largest urban forests in the nation.
Due to excessive urban stormwater runoff discharged to the forest over several years, the site has experienced severe damage to its health and integrity, including massive erosion, sedimentation, and pollution.
Two interconnected 15′ DoubleTrap underground vaults were installed at Hitchcock Woods to store and control the stormwater runoff.
The StormTrap basins provide approximately 25 acre-feet of stormwater storage within the Sand River watershed. Each basin was built with 368 and 902 precast concrete modular pieces, respectively.
The Sand River Stormwater BMP Implementation was complete by November 2022. At this time, this is the largest underground stormwater management system installed in South Carolina.
A passive park was built overtop these facilities as part of the site restoration serving as a new, grand entryway into the Hitchcock Woods.
