The "Sponge Cities" concept is very similar to Low Impact Development (LID). LID commonly incorporates numerous best management practices to achieve environmental and economic benefits. Recommendations in this study for cluster subdivisions regulations, setbacks and riparian preservation, and low impact development regulations support the "Sponge Cities" concepts. In addition to these recommendations, there are many other voluntary practices that can be implemented by the public such as the installation of rain gardens, green roofs, using pervious pavement, and amending soils to increase infiltration, reduce runoff, and improve water quality.
Typically, these practices work well in more frequent rainfall events (i.e. smaller rainfall events that occur more often) and consequently work well for the purposes of stormwater quality. However, the "Sponge Cities" concept is typically less effective for larger rainfall events because the runoff volume greatly exceeds the capacity of the LID components to hold runoff. The intensity of rainfall in larger events can also create more runoff than the LID features can infiltrate. LID will not provide significant flood control benefits unless the LID practices are done very extensively and with significantly more capacity in both existing and developing areas.
