Laval Stormwater Bylaw Requirements for Contractors
Laval, Quebec requires contractors and builders to follow municipal stormwater best practices during construction to protect drainage systems, watercourses and adjacent properties. This guide explains typical obligations on-site, inspection and complaint pathways, and practical steps to reduce runoff, sediment and pollution during all phases of work. It links to Laval's official municipal bylaws and permitting pages so contractors can confirm requirements and submit applications. See municipal bylaws[1] and permits and inspections[2] for authoritative details.
Common contractor obligations
- Install and maintain erosion and sediment controls (silt fences, sediment traps) for the duration of works.
- Obtain any required municipal permits or authorizations before beginning grading, drainage or discharge works.
- Prevent unauthorized discharge of sediment, oil, concrete wash water or other contaminants to storm sewers and natural waterbodies.
- Keep records of inspections, maintenance, and corrective actions on-site for review by inspectors.
- Comply with seasonal or weather-related restrictions specified by the city or permit conditions.
Site best practices
Contractors should prepare a simple stormwater management plan for the site that identifies run-off routes, erosion controls, staging areas and stabilization timelines. Ensure equipment refuelling and wash areas are located away from drains, and that disturbed soil is stabilized within the timelines required by permits or the municipality.
