Remediation of Urban Stormwater Using Best Management Practices and Low-Impact Development Green Infrastructures

There are many factors to determine the long-term effectiveness of a BMP such as the maintenance performed on the structure, the health of the plant life, the age of the structure, climate conditions, and public knowledge on the purpose of BMPs. Over the lifetime of the BMP the plant life in the structure will eventually die off, weeds and other invasive plant species will propagate crowd out the native plants in the structure, sediment and refuse will clog physical structures, and the BMP will take structural damage. To establish a BMP performance index, it is necessary to first determine a benchmark for performance. The effectiveness of a BMP decreases over time and the amount of stormwater remediation decreases. The decrease in effectiveness over time can be charted and used to determine a maintenance schedule and important optimization milestones.
