“Since January 2024, developers in Leuven have had to demonstrate that any rain that falls on new or significantly renovated homes can either be capture and re-used on-site or filtrate into the property’s garden rather than pool up and cause a flood.”
Depave in Portland has pulled up more than 33,000 sq m of asphalt since 2008 and diverts about 24.5 million gallons of rain from storm drains a year. Leuven removed 6,800 sq m in 2023 alone and sends a “tile taxi” to haul away your cobblestones. Leuven made developers pay for their own runoff, which is the part most cities skip.
