Dike Design & Construction Guidelines

Good dike design practice involves a variety of activities each aimed at ensuring that the new, repaired, upgraded or changed works are constructed to an appropriate standard.

The following guide has been developed to present basic principles used in the design and construction of dikes. The guidelines discuss sound engineering practices and help to address issues that a design professional may typically encounter.

Climate Change

The Climate Change Adaption Guidelines are intended to inform and encourage engineers, planners and others to address sea level rise. These reports are for information only and do not represent official B.C. Government policy.

The report below provides an estimate of the cost to construct flood protection to meet the rise in sea level predicted by 2100. The study area covers Metro Vancouver coastal shorelines and Fraser River shorelines west of the Port Mann Bridge.


This document provides guidance and information for qualified professionals to consider when conducting seismic designs of high-consequence dikes located in Southwestern British Columbia.


This guide discusses the design and construction of protective works to prevent erosion of river banks and dike slopes from stream flow.


These guidelines present minimum standards for managing vegetation on flood control structures in a manner that protects public and environmental safety.

Flood Profiles & Scenarios

Hydraulic modelling is used to generate flood profiles and flood scenarios. The B.C. Government uses these profiles and scenarios in dike engineering and land use planning.
