Understanding Swales

Swales play an important role in stormwater management, helping slow and absorb rainwater to reduce flooding. A swale is a shallow, grassy depression—typically wider than it is deep—commonly found along streets, sidewalks, parking lots, and driveways.

In recent years, heavy rains and tropical storms have shown how vital swales are to keeping neighborhoods safe. When trees or debris block swales and storm drains, water can back up, roots may damage underground pipes, and flooding becomes more severe.

By keeping swales clear and healthy, we can:

• Reduce flooding during heavy rains

• Protect infrastructure from tree roots and debris

• Improve water quality by filtering stormwater naturally

With South Florida’s rainy season and frequent storms, caring for your swale is a simple but powerful way to support your community and protect your home.

Swale Guidelines:

• Regular Mowing - Keep the grass in the swale area healthy and under control by mowing it regularly.
• Minimal use of Chemicals - Reduce the use of fertilizers, pesticides, and herbicides on both your lawn and the swale area.
• Proper Irrigations - Avoid over-watering the swale; adjust the irrigation to prevent standing water when it hasn't rained.
• Clear of debris - Keep the swales free of litter , branches, leaves, and limbs. Do not plant shrubs or hedges along the swale to ensure water can soak into the ground.
• Avoid paving - Refrain from paving or laying asphalt/cement on the swale area unless it's for a permitted driveway approach.
• No parking - Avoid paring cars on the swale, as it compacts the soil and hinders stormwater absorption.
• Preserve natural drainage features - Do not alter the swale's natural slope, as it my disrupt it's drainage functionality.
• Report if you see - Illegal dumping, clogged storm drains, or overflowing manholes by calling Public Works.
