Advanced Stormwater Management Built for Urban Density
At Earth Development, we help commercial general contractors and developers in Metro Atlanta manage stormwater with more innovative, space-saving systems that meet today’s stringent regulations, without sacrificing buildable real estate. Our Underground Stormwater Detention Systems are turnkey-installed using GPS-guided grading, zero-incident safety protocols, and deep coordination expertise that keeps your project on schedule and inspection-ready.
From retention structures to advanced outlet control features, we deliver everything your site needs, below grade and ahead of schedule.
Underground Retention Ponds
Maximize Buildable Space Without Sacrificing Compliance
Unlike traditional open ponds, underground retention systems enable the storage of stormwater beneath parking lots, driveways, and green spaces, thereby freeing up surface area for development while ensuring drainage compliance.
Our Underground Retention Systems Feature:
- Modular Storage Units: Engineered chambers, pipes, or crates that provide scalable detention capacity.
- Integrated Runoff Collection: Captures rainwater from rooftops, hardscapes, and subgrade systems.
- Custom Sizing for Site-Specific Storm Events: Installed to meet local and federal compliance benchmarks.
- Space Optimization: Installed beneath active-use areas like parking lots or sports courts.
- Turnkey Installation: Earth Development handles excavation, chamber setting, backfill, compaction, and tie-ins, all with one expert team.
We help you reclaim your surface while complying with the municipality’s post-construction stormwater ordinances.
Outlet Control Structures
Engineered for Controlled, Compliant Water Discharge
An underground system is only as effective as the structure controlling its outflow. Earth Development installs Outlet Control Structures to regulate discharge rates with pinpoint precision, ensuring water is released slowly, safely, and in full regulatory compliance.
Key Components We Install:
- Multi-Stage Riser Structures: Handle varying storm intensities with tiered flow release.
- Orifice Plates and Weirs: Sized to your system’s capacity and local hydrology requirements.
- Energy Dissipation Features: Reduces velocity to prevent downstream erosion.
- Access Ports and Cleanouts: For maintenance-friendly operations.
- Connection to Detention and Overflow Systems: Seamlessly integrates with your site’s overall drainage infrastructure.
All structures are positioned with GPS Auto Grade equipment to guarantee elevation and slope accuracy.
