Flooding Prevention in Heavy Rains: Strategies and Mitigation in British Columbia

British Columbia, with its diverse landscapes and proximity to the Pacific Ocean, is no stranger to heavy rains and the potential for flooding. To address this recurring challenge, a combination of proactive measures and innovative solutions, including hydro excavating, plays a crucial role in flood prevention and mitigation. In this article, we will explore various strategies and approaches for preventing flooding in British Columbia during heavy rains.

Clearing Storm Drains

One of the primary steps in flood prevention is keeping storm drains clear of debris and obstructions. Blocked storm drains can lead to localized flooding and pose a significant risk to communities. Regular maintenance and cleaning of storm drains ensure that rainwater can flow freely, reducing the risk of flooding in urban areas.

House Gutter and Rainwater Downspout Maintenance

A common source of flooding in homes is clogged gutters and downspouts. Ensuring that gutters and downspouts are clear of leaves and debris allows rainwater to be directed away from the foundation of the house, preventing basement flooding and water damage.

Sump Pump Provision

Installing sump pumps in basements is an effective way to prevent flooding. These pumps remove excess water from the area and direct it away from the property. Regular maintenance and testing of sump pumps are essential to ensure they function properly when needed.

Backflow Prevention Device Installation

Backflow prevention devices are critical for preventing sewage backup during heavy rains. These devices prevent contaminated water from flowing back into homes and businesses, safeguarding public health and preventing property damage.

Sandbags Provision During Heavy Rains

Sandbags are a traditional yet effective method for flood prevention. Placing sandbags strategically around vulnerable areas can divert and control water flow, protecting homes and infrastructure.

Demountable Flood Control Barrier System Installation

Innovative flood control barrier systems are gaining popularity in British Columbia. These systems are designed to be easily assembled and disassembled when needed, providing a flexible solution for flood prevention. They can be deployed to protect specific areas or entire communities during heavy rains.

Cleaning Clogged Drains

Clogged drains, whether in homes or public infrastructure, can exacerbate flooding issues. Regular inspections and cleaning of drains, including catch basins and culverts, help ensure that water can flow unimpeded, reducing the risk of flooding.

Hydro Excavating for Flood Mitigation

Hydro excavating is an advanced method that uses high-pressure water and vacuum technology to safely dig and remove soil. This technique can be a valuable tool in flood prevention and mitigation. Here’s how it can be used effectively:

1. Clearing Blocked Drainage Systems: Hydro excavating can efficiently clear blocked storm drains, culverts, and sewer lines, ensuring that rainwater can flow freely.
2. Creating Trenches for Drainage: Hydro excavation can be used to create trenches for improved drainage systems. These trenches can direct rainwater away from vulnerable areas and into designated water channels.
3. Excavating for Flood Barriers: Hydro excavation can be employed to create foundations or spaces for demountable flood control barriers. This precise method ensures that barriers are securely installed and can be easily removed when the threat has passed.

Preventing flooding during heavy rains in British Columbia requires a multi-faceted approach. Clearing storm drains, maintaining gutters, and installing preventive devices are essential steps. Additionally, innovative solutions like demountable flood control barriers and the use of hydro excavating technology can provide effective flood prevention and mitigation strategies. By implementing these measures and staying vigilant, communities in British Columbia can better protect themselves from the risks associated with heavy rainfall and potential flooding.

Coast Hydro Excavating is working with City West with a federal contract to place subsea fibre-optic cable, stretching from Prince Rupert, south to Vancouver, then around Vancouver Island. Currently, Coast Hydro is working with City West in the Sayward area to assist the directional drilling crews by locating the depth and position of underground services such as sewer, water and hydro. As existing village blueprints might be out of date, hydrovac is used when the fibre is laid under streets, driveways and parking lots.

Sayward is located in the Strathcona Regional District and the following communities will benefit from the Connected Coast Project:

  • Cortes Island
  • Gold River
  • Kyuquot
  • Quadra Island
  • Sayward
  • Tahsis
  • Zeballos

In total, it is estimated that the project has the potential to benefit 175,000 British Columbians living in 90,000 households.

Lafarge’s Texada Quarrying Ltd. has been operating the quarry since 1998. According to Jonathan Moser, Director of Environment and Public Affairs at Lafarge, “We believe it’s a 200-plus year deposit.” The mine currently employs about 90 people.

Two Coast Hydrovac trucks help get the quarterly maintenance completed. Our hydrovac trucks were on service to help complete the mine maintenance, including cleaning the large conveyor belt of debris.
