Integrated Parking & Stormwater Storage

Summary

Underground parking garages and basements are often first to flood during severe rain events, this concept proactively combines green and traditional surface and subsurface stormwater retention and flood management systems with underground parking to integrate their design for cost savings and connect two separate revenue streams, water rates and parking fees. Installation of underground district-scale water management systems could also help city agencies and building owners reduce the energy costs of pumping out water in areas with high groundwater tables or significant chronic flooding.
