The specifier was looking for a solution that would improve the treatment of urban stormwater runoff as well as eliminate any excess water in the park. After a heavy rainfall, the park often experienced flooding, which made the park less usable.
The park already had two storm drains and water quality units that covered about six acres of local neighborhoods, but the water from these drains would eventually flow into a nearby creek – and then make its way into the ocean – so it was critical to find a solution that could ensure water quality improvements.
StormChamber System Addresses Water Quality
The NDS Design Worx® team recommended an underground drainage solution that included the installation of approximately 100 NDS StormChamber units. This equated to 11,212 cf. of storage beneath the surface of the park. The system is highly effective at improving water quality and would help eliminate the excess water in the park, allowing the city to utilize the space above ground for recreation.
