CityLab: Paris Wants to Grow ‘Urban Forests’ at Famous Landmarks

Under a plan announced last week by Mayor Anne Hidalgo, thickets of trees will soon appear in what today are pockets of concrete next to landmark locations, including the Hôtel de Ville, Paris’s city hall; the Opera Garnier, Paris’s main opera house; the Gare de Lyon; and along the Seine quayside.

The new plantings are part of a plan to create “islands of freshness”—green spaces that moderate the city’s heat island effect. It also falls into an overall drive to convert Paris’s surface “from mineral to vegetal,” introducing soil into architectural set-piece locations that have been kept bare historically. As a result, the plan will not just increase greenery, but may also provoke some modest rethinking of the way Paris frames its architectural heritage.

While “forest” might be far too big a term for plots this modest in size, the plans as a type are necessary if Paris is to meet its ambitious greening goals. By 2030, city hall wants to have 50 percent of the city covered by fully porous, planted areas, a category that can include anything from new parkland to green roofs. This means that, when it comes to planting, pretty much any urban space needs to be up for grabs. [...]

As the mayor notes in this interview with newspaper Le Parisien, traffic on Paris’s roads has been reducing at a rate of 5 percent every year during her term, a reduction that is not always apparent on the roads because car lane space has also been reduced. With the number of cars steadily falling, Hidalgo has suggested steadily removing parking spaces and replacing each one with mini-gardens, a process that is due to start already this year on Avenue Daumesnil, an axial thoroughfare bisecting the city’s southeast.
