Have you seen SWALE YEAH! yard signs around the city? What are they about?
Many people aren't aware they are traveling right by a piece of property that is working hard to do good things. Swales are low, shallow channels designed to manage water runoff, filter pollutants and increase groundwater recharge. They are an essential feature in sustainable landscaping and urban planning, offering a natural and effective solution to stormwater management.
Swales are constructed or can be natural depressions in the landscape that capture and convey stormwater. They are typically lined with vegetation, such as grasses and native plants, which help slow down the flow of water, allowing it to seep into the ground gradually. This process not only reduces the volume of runoff but also filters out pollutants before they reach larger bodies of water like our Spokane River or Spokane Valley-Rathdrum Prairie Aquifer.
What are the Benefits of Swales?
Ever wondered what makes swales so beneficial to our ecosystem, especially in Spokane? Below are just some of the benefits of swales, that tend to hide in plain sight but are working hard for us every day whether we realize it or not!
When designing a swale, it's important to consider the slope, soil type and vegetation. A gentle slope ensures water moves slowly, maximizing infiltration. The choice of vegetation is crucial for both aesthetics and functionality; native plants are often preferred for their adaptability and low maintenance requirements. Swales are a practical and environmentally friendly solution for managing stormwater. They offer multiple benefits, from reducing runoff and pollution to enhancing local ecosystems and groundwater recharge. As urban areas continue to expand, integrating swales into landscape design and city planning will be vital for sustainable water management and environmental protection.
