What it is

A watercourse crossing is a structure placed in or over a watercourse. Normally it is a plastic or metal culvert, or a wooden bridge.

Standards and assessment

Look for alternatives first. Before building a permanent crossing, consider:

Get the permit. Any crossing, temporary or permanent, needs a watercourse alteration permit from the Environment Division of the Department of Environment, Energy and Climate Action.

Follow the guidelines. Construction must comply with the provincial Watercourse, Wetland and Buffer Zone Activity Guidelines (Government of PEI website).

Rules that apply at every crossing

RuleStandard
TimingNew crossing work normally June 1 – September 30, unless it fixes an existing erosion problem
Heavy equipmentNot within 15 m of a watercourse without a permit
DebrisRemove anything entering the stream immediately. Fallen trees lying in the watercourse within 5 m of the structure count as debris.
Older, unpermitted crossingsHave a PEI Forests, Fish and Wildlife professional check them before a road is re-established

The general road rules near water are on Roads & Water Diversion.
