It is a good idea, as this article from Meeting of the Minds notes, hat tip to Urban Exus, http://www.urbanexus.com
“When it comes to water sustainability and climate resilience, urban outdoor landscapes represent a wealth of opportunity.
“Outdoor landscapes are a vital component of our cities. Whether it’s outside a home, a store, an office, or a manufacturing plant, the landscape is a property’s primary interface with the community and the environment. Properly designed and managed using sustainable landscape strategies, these outdoor areas can help communities weather droughts, mitigate floods, sequester carbon, improve human well-being, and more.
“We can build sustainable landscapes, by which I mean landscapes that are in balance with local climate and ecology and actively contribute to watershed health. Key elements of sustainable landscapes include:
- Building healthy soils
- Preserving vegetative cover
- Using climate-appropriate plants
- Conserving water and other resources
“This could include strategies like removing turf, building rain gardens, or installing permeable pavement or rain tanks.
“To achieve sustainability, we need to make some changes.
“Take California, my home state, as an example. California has notoriously variable precipitation patterns, and this is increasing with climate change. We are seeing longer and hotter droughts, and more intense storms; and more dramatic fluctuations between these two extremes. This means that our cities are facing increasing threats of water shortage on one hand, and flooding on the other.
“Our current urban landscapes, marked by big lawns and paved areas, don’t do much to alleviate these problems. In fact, in many cases, they exacerbate them. Thirsty turf grass requires a lot of irrigation, especially in the peak of summer when it’s dry and hot, and water is in shorter supply. Over half of urban water use in California goes to landscape irrigation, and that portion is higher in the summer. Vast expanses of pavement—parking lots in particular—leave no place for rain water to go but down the drain, which has limited capacity to handle intense storms, leading to flooding and pollution.
“There is a better option.
“We can turn our urban landscapes into assets for climate resilience, rather than a source of risk. For example, look below at this side-by-side case study of two residential yards in Santa Monica, California (sustainable landscape on the left, traditional landscape on the right). Nine years of monitoring both landscapes showed that the sustainable landscape uses 83 percent less water, creates 56 percent less green waste, and requires 68 percent less maintenance than the more traditional landscaping.”
