Stormwater

Stormwater moves through a connected system of natural and built features across the community.

When it rains:

• Water flows over roads, rooftops, and other hard surfaces
• It enters ditches and catch basins, which collect and direct runoff
• It moves through culverts, allowing water to pass beneath roads and driveways
• It continues through ditches and natural watercourses
• It is ultimately released into creeks, wetlands, and the Sooke Harbour and Basin

Culverts play an important role in this system by maintaining the natural flow of water while allowing it to safely pass under roads and other infrastructure.

During heavy rainfall, water moves more quickly through the system and can exceed capacity in some areas, which may lead to localized pooling or flooding.

Water eventually flows into creeks, wetlands, and the ocean.

The District manages municipal stormwater infrastructure, including ditches, culverts, and drainage systems.

We work to reduce flood risk, maintain proper drainage, and protect the environment—especially creeks, wetlands, and the Sooke Harbour and Basin.

During heavy rainfall, the District responds to stormwater concerns, such as flooding, on a priority basis. Priority is given to locations where there is a higher risk to public safety, property, or critical infrastructure.

Residents play an important role in keeping our stormwater system working well. You can help by:

• Keeping leaves and debris out of roadside ditches and drains
• Properly managing runoff from roofs and driveways
• Avoiding dumping anything (paint, oils, wash water, yard waste) into drains or ditches
• Planting native vegetation to absorb water and stabilize soil
• Reporting blocked drains, flooding, or erosion to the District

Small steps at home help reduce localized flooding and protect water quality.

Stormwater management is a key part of all new development in Sooke.

Developers must follow the Subdivision and Development Standards Bylaw and provincial best practices to ensure:

• Runoff from new buildings and pavement is properly managed
• Natural drainage patterns are protected where possible
• On-site systems (e.g., swales, retention areas) are incorporated
• Erosion and sediment controls are in place during construction

This helps ensure that growth happens in a way that protects downstream properties and sensitive ecosystems.

Stormwater flows through the drainage system and is released directly into local creeks, wetlands, and the Sooke Harbour and Basin. It is not treated before entering the natural environment. That’s why it is important to:

• Avoid polluting runoff
• Reduce use of chemicals on lawns and gardens
• Maintain vegetated buffers near waterways

Keeping contaminants out of stormwater is a simple way to protect salmon, wildlife, and sensitive habitats.

Sooke experiences increased rainfall, especially during fall and winter. To reduce risk during heavy rain events:

• Clear gutters and downspouts
• Keep nearby culverts and ditches free of debris
• Ensure sump pumps are functioning
• Report flooding concerns promptly

The District monitors high-risk locations and responds to drainage concerns on a priority basis.

No. Stormwater flows directly into natural water bodies. Only the sanitary sewer system goes to the Wastewater Treatment Plant.

The District maintains ditches and drains along municipal roads. Driveway culverts are privately owned and must be maintained by the property owner.

Blocked ditches can cause localized flooding, property damage, and road hazards. Keeping ditches clear helps water flow safely.

If safe to do so, check for debris and clear leaves or branches. If flooding persists, contact the District.

A culvert is a pipe or structure that allows water to flow beneath roads, driveways, or pathways. It helps move stormwater through the drainage system while keeping roads safe and passable. 

Culverts are an important part of both the stormwater system and the road network, helping prevent flooding, erosion, and damage to infrastructure.

The District maintains culverts located within municipal road right-of-way as part of its road maintenance program.

Driveway culverts are the responsibility of the property owner and must be kept clear to allow water to flow properly.

Culverts under municipal roads are monitored and maintained as part of the District’s road maintenance program. This may include:

• Inspecting culverts on a regular cycle
• Clearing debris and sediment buildup
• Repairing or replacing damaged structures over time

Maintenance is prioritized based on factors such as flood risk, condition, and potential impacts to roads and properties.

Culverts located under private driveways are the responsibility of the property owner and should be kept clear to allow water to flow properly. Keeping these culverts free of debris helps reduce the risk of localized flooding and drainage issues.

If it is safe to do so, you can remove light debris such as leaves or branches from the culvert opening—especially if it is located near your property or under your driveway.

Property owners are responsible for maintaining driveway culverts and keeping them clear to allow water to flow properly.

If the blockage is within the municipal road right-of-way, or if water continues to pool after clearing, report the issue to the District so it can be assessed and prioritized as part of the road maintenance program.

Green infrastructure uses natural processes, like rain gardens, bioswales, and permeable surfaces, to absorb and filter stormwater. It reduces flooding and protects water quality.
