Our work aims to address gaps related to Green Infrastructure (GSI) longevity, efficiency, and maintenance needs. By evaluating mature GSI systems and documenting our findings, we aim to develop a standard method that can be widely applied in the Great Plains region, and beyond.
What is GSI forensics?
It is the method of scientifically evaluating known stormwater management practices and strategies in order to collect and disseminate knowledge that promotes potential benefits to communities, infrastructure, ecosystems, and overall resilience. Our work supports professionals in infrastructure design and construction, landscape maintenance, local and tribal governments, along with curious and informed citizens, who are integral in the process of implementation and adoption.
GPSCOE GSI Forensics Strategy:
1. Document review to understand the design and provide feedback (as needed).
2. Operations and maintenance review with practice owners and operators (more detailed consulting).
3. Performance Evaluations
Visual Assessment
- Inlet/outlet structure
- Debris accumulation
- Vegetation assessment
Measurements
- Infiltration
- Pollutant Accumulation
- Soil density
Select systems will be instrumented with water sampling equipment and trail cameras to capture system performance during runoff events and document the use of stormwater BMP systems by wildlife.
