A bioswale is a landscaping feature that helps manage rainwater and prevent flooding. Think of it as a natural drainage system - like a shallow ditch filled with plants, rocks, and special soils that clean and filter rainwater. Landscapers create these features in parking lots, along roads, or in parks to help protect the environment and meet local water management rules. They're becoming more popular as cities and businesses focus on "green infrastructure" and sustainable landscaping. You might also hear them called "rain gardens," "filter strips," or "drainage swales," but they all serve the same basic purpose.
