What is the main purpose of Best Management Practices (BMPs) in stormwater management?

The main purpose of Best Management Practices (BMPs) in stormwater management is to prevent pollution and manage stormwater runoff effectively. BMPs are techniques or measures that are designed to minimize the adverse impacts of stormwater on the environment. These practices can include various strategies such as retention ponds, vegetated swales, and filtration systems that help to treat and control stormwater before it reaches natural waterways.

By implementing BMPs, communities and developers can reduce the amount of pollutants that enter stormwater systems, thereby protecting water quality in lakes, rivers, and coastal areas. Additionally, BMPs help manage the quantity of stormwater runoff, mitigating issues such as flooding and erosion. The effectiveness of BMPs in addressing these environmental concerns underscores their importance in promoting sustainable development and protecting aquatic ecosystems.
