BMP Visual Assessments

Regular inspection of stormwater best management practices (BMPs) is critical to ensure they are functioning as designed. If stormwater isn't being diverted off roadways and into the structures, pollutants can't be removed from the contaminated water. 

​

BMPs need to remain free of trash, leaves, sediment, and debris that would obstruct stormwater from flowing into and out of the structure and slow down proper drainage rates. If stormwater isn't draining into the ground within 48 hours after a rain event, there is likely a problem with the performance of soils in the structure. 

​

Healthy and proper vegetation plays a critical role in BMPs’ success, soaking up and filtering nutrients from stormwater runoff. 

​

Photo and video documentation of BMPs over time is also essential to tracking their long-term effectiveness.
