text: Some people might expect that green spaces are extravagant and excessively difficult to maintain, but high-performing green spaces can provide tangible economic, ecological, and social benefits. For example:
  * Urban forestry in an urban environment can supplement stormwater management and reduce associated energy usage costs and runoff.
  * Bioretention systems can be applied to the creation of a green transportation system.
  * Lawn grass is not an answer to runoff, so an alternative is required to reduce urban and suburban first flush (highly toxic) runoff and to slow the water down for infiltration. In residential applications, water runoff can be reduced by 30% with the use of rain gardens in the homeowner’s yard.  A minimum size of 150 sq. ft. up to a range of 300 sq. ft. is the usual size considered for a private property residence. The cost per square foot is about $5–$25, depending on the type of plants you use and the slope of your property. Native trees, shrubs, and herbaceous perennials of the wetland and riparian zones being the most useful for runoff detoxification.
  As a result, high-performing green spaces work to create a balance between built and natural environments. A higher abundance of green space in communities or neighbourhoods, for example, has been observed to promote participation in physical activities among elderly men, while more green space around one's house is associated with improved mental health.
  In addition to these benefits, recent studies have shown that residents highly value the experiential aspects of green infrastructure, emphasizing the importance of aesthetics, wellbeing, and a sense of place. This focus on cultural ecosystem services suggests that the design and implementation of green infrastructure should prioritize these elements, as they significantly contribute to the community's perception of value and overall quality of life.
