Urbanization often results in issues such as flooding, pollution, and fewer open spaces. LID is a smart way of managing such issues that make cities more livable and sustainable.
What is LID?
LID is a way of designing cities which works with nature. It has its focus on managing rain where it falls; hence, reduces runoff and prevents environmental degradation. In place of massive drainage systems, LID resorts to simple eco-friendly solutions.
Common LID Practices
Green Roofs: Plants on rooftops soak up the rain, reduce heat, and clean the air.
Rain Gardens: Small gardens collect and absorb rainwater, thus preventing flooding.
Permeable Pavements: Special materials allow water to pass through, thus reducing puddles and runoff. Learn how permeable pavements are beneficial in stormwater management.
Bioswales: Ditch-like areas with plants clean and slow down stormwater.
Rainwater harvesting: Catching the rain for use in irrigation and for other uses later on.
Why LID is Important
Preserves Nature: Reduces contaminants from entering local water bodies.
Controls Flooding: Enhances proper control over stormwater in large amounts of rain.
Saves Money: It costs less to erect compared to the bigger stormwater system.
Beautifies Cities: Incorporating greenery makes the place look even more attractive and serene.
Disadvantages
- Has the disadvantage of offering some high-upfront costs; for example, green roof solution.
- Regular maintenance on working systems.
- Community awareness and support are needed to make it successful.
LID Success Stories
- Portland, USA: Known for its green streets and bioswales.
- green streets program. Singapore: Integrate rainwater storage with green parks into urban designs.
- New York City: Incorporates rain gardens and green roofs in fighting flooding.
Conclusion
Low-Impact Development is a concept of constructing cities in line with nature instead of against nature. Ideas that are very simple, such as planting rain gardens or using permeable pavements, can make the difference. In adopting LID, cities may become cleaner, greener, and better to live in.
