Back to BMPs Overview
Post-Construction Stormwater Management
Post-construction stormwater management practices are permanent measures designed to reduce pollutants in stormwater runoff from completed development projects. These controls must be maintained throughout the life of the development.
Structural Controls
Permanent infrastructure for long-term stormwater management.
Infiltration Systems
- Bioretention areas
- Rain gardens
- Infiltration trenches
- Permeable pavements
Detention Systems
- Extended detention basins
- Underground storage
- Constructed wetlands
- Green roofs
Water Quality Treatment
Practices designed to remove pollutants from stormwater runoff.
Filtration Systems
- Sand filters
- Bioswales
- Filter strips
- Media filtration units
Separation Devices
- Oil/water separators
- Hydrodynamic separators
- Catch basin inserts
- Baffle boxes
Long-Term Maintenance
Requirements for ensuring continued effectiveness of post-construction BMPs.
Inspection Program
- Regular performance evaluations
- Maintenance schedules
- Documentation requirements
- Corrective action procedures
Operation Guidelines
- Maintenance agreements
- Staff training programs
- Replacement schedules
- Budget planning
Design Considerations
- Site-specific conditions and constraints
- Long-term maintenance requirements
- Cost-effectiveness of selected practices
- Integration with site landscaping
- Compliance with local regulations
