Depaving, also known as desealing, is the act of removing impermeable surfaces such as parking lots and replacing with a permeable surface, especially green space.^[1]^[2] Depaving can help manage stormwater runoff, ensuring that runoff is less polluted.^[3]

The Depave Portland group in Portland, United States says that it has depaved more than 70 parking lots and removed 150,000 square feet (14,000 m²) of paving since it was founded in 2008.^[4] Some cities, including Portland, charge impervious pavement fees to cover the cost of dealing with runoff, which incentivizes depaving.^[2] Eindhoven, Netherlands depaved parts of its area.^[5] The city of Leuven, Belgium is planning depaving as part of its Leuven2050 plan to become carbon-neutral and combat the urban heat island effect.^[6]^[7] Other motivations for depaving include providing habitat for wildlife,^[8] combating climate change or increasing quality of life by replacing underutilized paved areas with green space.^[1] A 2020 study found that depaving had high effectiveness for increasing groundwater replenishment.^[5]

According to a 2016 study by the Transportation Research Board of the National Academies, depaving is common on rural roads as a cost-saving measure due to the high cost of maintaining paved surfaces.^[9]
