Additional Benefits:
- Prevents soil erosion
- Easy to integrate into existing landscapes
- Low maintenance solution for flood control
8️⃣ 🌱 Tree Canopy Preservation
Description: Maintaining and expanding tree canopy coverage can significantly reduce flood risks. Trees act as natural sponges, absorbing water through their roots and releasing it slowly into the atmosphere. They also improve soil structure, reducing runoff and flooding in urban areas.
Additional Benefits:
- Reduces heat island effect in cities
- Enhances property value
- Improves air quality and reduces carbon footprint
9️⃣ 🌾 Constructed Wetlands
Description: Constructed wetlands are artificial ecosystems that mimic the natural filtering processes of marshes. These wetlands slow the flow of water, allowing sediment and pollutants to settle out before the water is absorbed or released downstream. They are highly effective for flood mitigation in large areas.
Additional Benefits:
- Acts as a wildlife habitat
- Enhances biodiversity
- Filters pollutants and improves water quality
🔟 💧 Rainwater Harvesting Systems
Description: Rainwater harvesting systems collect and store rainwater from rooftops for later use, reducing stormwater runoff and the risk of flooding. These systems are simple to install and can be used for irrigation or non-potable water needs.
Additional Benefits:
- Reduces water bills
- Provides a sustainable water source during droughts
- Lowers the risk of overloading stormwater systems

Additional Benefits:
- Improves urban resilience to heavy rainfall
- Reduces the need for artificial stormwater systems
- Increases water reuse and recycling potential
1️⃣3️⃣ 🏞️ Floodplain Restoration
Description: Restoring natural floodplains involves returning developed or altered land to its natural state, allowing it to store excess water during heavy rains. This can significantly reduce the risk of flooding downstream by providing space for water to spread out and slowly be absorbed.
Additional Benefits:
- Supports biodiversity and wildlife habitats
- Improves ecosystem services like water purification
- Helps in carbon sequestration through natural vegetation
1️⃣4️⃣ 🌿 Detention Basins
Description: Detention basins are engineered areas designed to temporarily hold and slowly release stormwater runoff.
