Stormwater Control
The comprehensive set of practices, infrastructure, and policies designed to manage precipitation runoff in urban and developed areas to prevent flooding and protect water quality.
Stormwater Control
Stormwater control encompasses the systematic management of rainfall and snowmelt in developed areas, representing a critical intersection of urban planning and environmental protection.
Core Components
Infrastructure
- Detention basins for temporary water storage
- Bioswales and rain gardens for natural filtration
- Permeable pavement systems
- Underground storage tanks and tunnels
- Green roofs for rainfall capture
Management Practices
-
Source Control
- Reducing impervious surfaces
- Implementation of erosion control measures
- Strategic landscape design
-
Treatment Methods
- Water filtration systems
- Sediment removal facilities
- Biological treatment processes
Environmental Benefits
Effective stormwater control delivers multiple environmental advantages:
- Prevention of urban flooding
- Protection of water quality
- Groundwater aquifer recharge
- Reduction of stream erosion
- Support for local ecosystems
Regulatory Framework
Stormwater management is governed by various regulations:
- Clean Water Act requirements
- Municipal separate storm sewer system (MS4) permits
- Local zoning laws and building codes
- Environmental impact assessment standards
Modern Approaches
Green Infrastructure
Modern stormwater control increasingly emphasizes green infrastructure solutions that:
- Mimic natural water cycles
- Provide additional ecosystem services
- Enhance urban aesthetics
- Support climate resilience
