Improperly maintained permanent stormwater quality features can increase the pollutants in our rivers, increase the amount of erosion that could occur, and even increase flooding risk. Over time, stormwater quality features can accumulate trash, sediment, vegetative debris, etc. that reduces storage capacity and functionality which could lead to flooding. Yearly maintenance ensures that trash, vegetation, and debris accumulation does not compromise your stormwater quality feature’s functionality. As monsoon season continues and we start to move towards the fall season, it is important to check your permanent stormwater quality features and perform routine maintenance to ensure these features are operating correctly and reducing potential flooding risk.
To ensure a permanent stormwater quality feature is operating as it should, it must receive routine inspection and maintenance. All permanent stormwater quality feature maintenance should include:
- Removing trash and vegetation debris from inlets, trickle channels, and outlet structures
- Preventing EDB and pipe system clogging by removing obstructions
- Cleaning and removing sediment from inlets, trickle channels, and outlet structures
If a flood were to occur due to an improperly maintained stormwater quality feature backing up or during or following a large rain event, it is always important to remember:
- Six inches of water will reach the bottom of most passenger cars causing loss of control and possible stalling
- A foot of water will float many vehicles
- Two feet of rushing water can carry away most vehicles including sport utility vehicles (SUV’s) and pick-ups
