Development of a Stormwater Detention/Infiltration System for Urban Highways Using Permeable Light-weight Cellular Concrete, Phase I

We propose developing a decentralized stormwater detention system using permeable cellular concrete (PLCC) as an “underground” detention/infiltration material. This system will benefit urban roadways where land or utility constraints do not allow for conventional detention and stormwater treatment. We believe the underground storage and infiltration of runoff can reduce the negative impacts of urban flooding on safety and roadway durability. This decentralized system will also benefit downstream waterways and groundwater by minimizing erosion, improving aquatic ecology, and providing in situ stormwater quality treatment.
