Seems like everyone has been looking for an cost--effective, low-impact, aesthetically-pleasing, filtration system for those pesky parking lot applications. We combined a state-of-the-art filtration system with a bioretention system, achieving several different goals:

• Accommodates heavy stormwater discharges, up to 9 Cfs each--(standard-sized unit)
  

• Low visual impact to surrounding areas--enhanced aesthetics with choice of grates / finishes
  

• Meets / exceeds vegetative requirements for developing properties
  

• Low annual maintenance cost with easi-access© debris removal
  

• Incorporates car-stop features (no more bumper to bumper impacts)
  

• Reinforced concrete (cast-in-place) units are H-20 load rated
  

• Units can be linked together, increasing drainage / filtration capacities in large parking lot areas
  

• Chambers can include perforated bases (optional) for groundwater recharging if desired
