Ottawa Flood Prevention Checklist for Property Owners
Ottawa, Ontario property owners face seasonal flood risks and must follow municipal rules to reduce damage and liability. This checklist explains practical steps, relevant city enforcement roles, permit and inspection pathways, and what to do before, during and after a flood to comply with Ottawa bylaws and reduce harm to people and property.
Preventive Actions for Property Owners
Start with a site assessment and basic maintenance to reduce local flood risk. Prioritize actions that reduce water entry, protect utilities and preserve drainage paths.
- Clear eavestroughs and downspouts and direct roof runoff away from foundations.
- Confirm lot grading and drainage swales are intact and free of debris.
- Store important documents, equipment and valuables above expected flood levels.
- Install or test backwater valves and sump pumps; have battery backup for power outages.
- Document property conditions with dated photos to support insurance or enforcement cases.
Stormwater, Lot Grading and Construction Considerations
Any alteration that affects drainage, grading or stormwater management can trigger permit or approval requirements under Ottawa rules and the Ontario Building Code or local conservation authority rules.
- Before altering grade or installing major drainage features, check permit requirements.
- Secure permits for new structures, retaining walls or driveways that change runoff patterns.
- Follow any conservation authority floodplain restrictions where applicable.
