How should new BMPs be assessed for effectiveness?

The assessment of new Best Management Practices (BMPs) for effectiveness is crucial in ensuring that they meet their intended goals of reducing stormwater pollution and managing runoff effectively. Regular monitoring and evaluation against pre-defined performance criteria is a systematic approach that allows for a thorough assessment of how well the BMPs are functioning under actual conditions.

This method provides empirical data on the BMPs' performance, which can include measurements of pollutant reduction, changes in water quality, and overall impact on stormwater management objectives. By establishing specific criteria beforehand, organizations can objectively evaluate the BMPs, identify areas for improvement, and make informed decisions about any necessary adjustments or enhancements.

In contrast to other methods, relying solely on public feedback may not provide a comprehensive or scientifically valid understanding of BMP effectiveness, as it can be subjective and influenced by individual perspectives. Using historical data can be informative, but it may not accurately reflect the current conditions, technologies, or ecological contexts relevant to the new BMPs being implemented. Comparing plans from different states may yield useful insights, but it often lacks the specificity and relevance required to assess the effectiveness of BMPs in the unique circumstances of a particular project. Thus, regular monitoring and evaluation based on established performance criteria stands out as the most effective and robust approach
