For this project, the Belleville en Beaujolais town council teamed up with the Aintegra Saône Beaujolais design office for the project management, and with a consortium comprising Eiffage Route Agence de Beaujeu (lead contractor) and Green Style for the construction. The primary objective was to implement a solution for the rational management of rainwater.

ÉcOasis® is a comprehensive solution for reducing urban heat island phenomena, with the aim of countering them by cooling the air by around 5°C. It combines permeable Bioklair® planted surfacing, a reservoir pavement system and appropriate vegetation.

The project at Belleville-en-Beaujolais involved laying CarbonLight® low-carbon asphalt for the roadway and Bioklair® permeable plant-based asphalt for the pavements. The buffer storage of around 500 m³, created under the entire roadway, acts as a reservoir for the new plant species planted along the pavement. Gutters from neighbouring homes connect to the reservoir under the road, limiting the risk of downstream flooding.

This operation marks a major step towards the bio-climatic town of the future for Belleville-en-Beaujolais.
