Parking Lots & Garages
During heavy rain events, a large amount of stormwater can quickly accumulate on the surface. Parking areas need a drainage system that can handle large amounts of water. A large inlet area and a good water flow coefficient are advantages that should be considered with channel systems.

Considerations
Loading
- Parking areas will need to withstand frequent car and truck traffic, a drainage system and grate with a minimum Load Rating of Class C or higher is recommended
- For pedestrian only areas, a system and grate with a minimum Load Rating of Class A is recommended. If wheeled carts are likely for deliveries then a higher load rating should be considered
Application
- Restricted construction depths may necessitate a shallow invert drainage system
- ADA compliant grates may be required in pedestrian access areas
- Wastewater from parking areas may contain hydrocarbons and an oil/water separator may be required
Areas with large run-off volumes may be ideal for modular water storage such as ACO StormBrixx
