Throughout many portions of Surrey there is an open drainage system of ditches that conveys stormwater to local creeks and streams. This open system may require the installation or upgrade of driveway culverts to allow access to properties. As this drainage system also supports a wide diversity of aquatic life and fish, construction works for culverts must be managed carefully so as not to damage the surrounding environment. The City of Surrey has prepared guidance documents to assist those who wish or need to install a driveway culvert.
These requirements will change depending on the classification of the ditch you are crossing.
