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.

Utility TrenchCase Studies
-
Lake County Health
ACO FlowDrain FG200 was installed at Lake County Tribal Health’s parking entryways and main lot to manage stormwater efficiently. The 1% built-in slope and ADA-compliant grates deliver high-capacity flow and safe pedestrian transitions. Long section lengths sped installation; 444 linear feet were installed to integrate with the site’s stormwater system. -
Lexington 7 Retail
ACO KlassikDrain K300 was installed at Lexington 7, a 66,000-square-foot retail and entertainment destination. The project required a trench drain that could withstand constant movement from frequent site traffic. Over 300 linear feet of K300 with Type 878Q grates were installed to manage runoff and reduce ponding. -
Loyola University Maryland
ACO KlassikDrain K300 was installed at Loyola University Maryland to provide discreet, efficient drainage without compromising design. Selected to complement the architecture of the new building and adjacent historic Beatty Hall, K300 quickly removes runoff to reduce slip hazards while aligning with the university’s Green Building Policy. -
Mount Timpanogos Utah Temple
ACO StormBrixx 900 SD replaced a failing French drain at the Mount Timpanogos Utah Temple, preventing visible ponding in parking and landscape areas. The HS-20 traffic rated system uses a column design to spread loads; three layers were installed quickly to deliver reliable underground storage with minimal surface disruption. -

Townhomes on 50th West
ACO StormBrixx 600 HD infiltration system was installed beneath the parking lot of a townhouse development to reduce flooding by absorbing and filtering stormwater. With a 95% void ratio, the modular cells provide high storage efficiency and quick, no-heavy-equipment installation, enabling fast assembly and long-term performance. -
Viva Rapid Transit Garage
ACO Oleopator P oil-water separator was installed at the Viva Rapid Transit Garage to capture hydrocarbons from washdown and stormwater. The unit removes oils, fuels, and fine particulates from runoff in service and parking areas, protecting water quality and supporting environmental compliance
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
