Two proposals are currently open for public consultation: the creation of a spillway channel along the RN 109 and the development of a flood expansion zone on the right bank of the Mosson at the Engarran site. These measures are intended to complement the section of the environmental impact study that addresses flood risk for the western bypass of Montpellier, known as the COM project. The western bypass is a major infrastructure project that involves redesigning a two-lane highway route, made up of several sections of metropolitan roads deemed too small for the current traffic levels. This addition to the project was mandated by a court decision. The project, declared of public interest by a ministerial decree on September 2, 2021, and later extended on July 27, 2026, involves the communes of Juvignac, Montpellier, and Saint-Jean-de-Védas. On July 21, 2026, the Toulouse administrative court of appeal found that the environmental impact study was lacking in its analysis of compensatory measures related to flood risk. However, the court noted that this deficiency could be corrected through a supplement to the study and a decree outlining the measures to be implemented. The electronic consultation, which opened this Friday, is part of this corrective process. To participate in the consultation, the public can review the project file and submit their observations and proposals until Monday, November 2, inclusive, via the public consultation platform of the ministry. The prefect of the Hérault has encouraged citizens to take part in this process, emphasizing that the project is considered structuring for the department. This means it is expected to have a significant and lasting impact on the region's infrastructure and development.
