Creating Continuous Green Spaces
Manage stormwater and enhance urban aesthetics
The “Green Urban Corridors for Water Management” project in Chiang Mai aims to create continuous green spaces that serve dual purposes: managing stormwater and enhancing urban aesthetics. These corridors integrate Water Sensitive Urban Design (WSUD) principles to transform the city’s infrastructure, making it more resilient and environmentally friendly.
Objectives
- Stormwater Management: Utilize green corridors to capture and manage stormwater, reducing urban flooding and minimizing runoff.
- Water Quality Improvement: Implement biofiltration systems within the corridors to filter pollutants and improve water quality before it reaches natural water bodies.
- Biodiversity Enhancement: Create habitats for various plant and animal species, supporting urban biodiversity and ecosystem health.
- Urban Cooling: Mitigate the urban heat island effect by increasing green spaces and providing shade, leading to cooler urban areas.
- Community Engagement: Provide accessible recreational spaces for residents and promote awareness of sustainable water management practices.
Key Features
- Permeable Pavements: Install permeable surfaces along the corridors to allow water infiltration, reducing surface runoff and replenishing groundwater.
- Rain Gardens and Bioswales: Develop rain gardens and bioswales to collect and filter stormwater, enhancing water quality and supporting native vegetation.
- Green Roofs and Walls: Incorporate green roofs and walls on adjacent buildings to manage rainwater, reduce energy consumption, and improve air quality.
- Public Spaces: Design parks and walking paths within the corridors, offering recreational areas and educational signage about WSUD practices.
- Integration with Traditional Architecture: Use elements of traditional Lanna architecture, such as wooden structures and intricate carvings, to blend modern water management with cultural heritage.
The Impact
Reduce Flooding,
Improve Water Quality,
Enhance Biodiversity
The project is expected to significantly reduce flooding, improve water quality, and enhance urban biodiversity in Chiang Mai. It will also create cooler, more livable urban environments and increase public awareness of sustainable water management.
