The winter road maintenance plan, coordinated by the Prefect of Police of Paris, aims to anticipate weather events, inform users, manage heavy goods vehicle traffic, and coordinate assistance operations. It includes four levels, from seasonal watch to the activation of the road safety plan in Cergy.
In critical situations, an on-call team of sixty agents and equipped vehicles are mobilized to secure the 70 km of roads and 35 km of sidewalks in the municipality. Coordinated and preventive interventions cover municipal roads, public works, public facilities (schools, nurseries, gyms), and dangerous areas, with limited salting for environmental reasons.
The city collaborates closely with the Cergy-Pontoise Agglomeration Community and the Val-d'Oise department. It is reminded that each resident is responsible for ensuring the safety of the sidewalk along their property for a minimum width of 1.5 meters.
