In Grenoble, a “freshness plan” to combat the growing heat

Faced with increasing and intense heat waves, the city of Grenoble announced on Thursday the implementation of a “freshness plan” with more green space, sprinklers and less concrete.

With global warming, the city of Grenoble and Météo France predict up to 50 days of heat in 2050, compared to 3 a year today. The agglomeration is located in a pool that can become suffocating in summer.

The municipality wants to “create cooler spaces for places to live,” notes her deputy for nature in the city of Gilles Namur, and “freshness comes through the water”.

With each new peak of heat, in Grenoble and elsewhere, the fountains turn into makeshift pools, when fire hydrants are not forcibly opened to create urban geysers.

To counter these forbidden phenomena, the city will set up several nebulae near ornamental pools, especially in the popular Mistral district, and temporary nebulae, hung high up to prevent damage.

These microcap projections “put us in acceptable sanitary conditions” and consume very little water, advance Gilles Namur, second deputy mayor, ecologist Eric Piolle.

“We have the will to reopen the fountains, to make them more accessible,” the deputy adds, and these blurs are an experiment that will expand if it succeeds.

Schools converted into recreation centers in the summer will use water play equipment, such as punctured pipes. New drinking tanks will also be set up, for example, along the new bike paths.

This “freshness plan” also emphasizes the goal of greening and “dehumidifying” the city, especially around schools. “Wood is an air conditioner,” says Mr. Namur.

The city plans in the long run to develop a water pool located south of the city, in the working-class district of Villeneuve, as a water body for authorized swimming. And remember, on a map dedicated to points of freshness, the capital of the Alps is surrounded by mountains and high lakes that can be accessed by bus.
