Green Belt Exercise:
Scenario: Imagine you are a city planner tasked with designing a new park that will serve as a green belt. The park is located on the edge of a residential area, bordering a river. Consider the environmental and water treatment benefits of a green belt when designing the park.
Task:
- List 3 features you would include in the park to improve water quality. (e.g., rain gardens, bioswales, etc.)
- Explain how these features would contribute to protecting the river.
- Suggest 2 ways to promote public awareness and engagement with the park.
Exercise Correction
1. Features for improving water quality:
- Rain gardens: These shallow depressions planted with native vegetation capture and filter stormwater runoff, reducing pollutants entering the river.
- Bioswales: Long, shallow ditches planted with vegetation that slow down stormwater flow, allowing water to infiltrate and filter before reaching the river.
- Riparian buffer: A strip of trees and vegetation planted along the riverbank that helps stabilize the soil, filter runoff, and provide shade, improving water temperature.
2. Contribution to river protection:
- Rain gardens and bioswales filter pollutants like fertilizers, pesticides, and oil from stormwater runoff before they reach the river.
- Riparian buffers act as natural filters, preventing erosion and sedimentation, which can harm aquatic life and water quality.
3. Public awareness and engagement:
- Educational signage: Place informative signs throughout the park explaining the benefits of green spaces and their role in protecting water quality.
- Community events: Host events like nature walks, river clean-ups, and planting days to engage the community and educate them about the park's importance.
