Montreal building more sponge parks, sidewalks to soak up heavy rainfall

The city of Montreal is planning to build more urban "sponge" infrastructure to protect against future flood waters brought on by climate change. The announcement Tuesday came as Montreal once again found itself drying out after heavy rainfall pummelled the city in the early morning. The city plans to build 30 sponge parks and 400 more sponge sidewalks by 2025  — green spaces that naturally absorb excess rainfall instead of draining the water directly into neighbourhood sewers.
