STANDARD D.F.O. REQUIRMENTS FOR BRIDGES

In order to comply with the Fisheries Act, it is recommended that you incorporate the following measures into your project proposal:

Culverts

• Ensure that fish migration through the culvert is maintained such that the structure will not create a velocity barrier to migrating fish or destabilize the channel downstream

• Embed water crossings as appropriate to ensure fish passage and channel crossing stability

Timing

• If you are conducting in stream work during periods of low flow to further reduce the risk to fish and their habitat no in-stream work or construction activity should occur from March 15th to June 30th

• If the drain is dry, work can proceed at any time of the year

Erosion and Sediment Control

• Install effective erosion and sediment control measures before starting work to prevent sediment from entering the water body

• Conduct regular inspections and maintain erosion and sediment control measures and structures during the course of construction

• Repair erosion and sediment control measures and structures if damage occurs

• Remove non-biodegradable erosion and sediment control materials once site is stabilized

Shoreline Re-vegetation and Stabilization

• Clearing of riparian vegetation should be kept to a minimum

• Immediately stabilize shoreline or banks disturbed by any activity associated with the project to prevent erosion and/or sedimentation, preferably through re-vegetation with native species suitable for the site

• If replacement rock reinforcement/armouring is required to stabilize eroding or exposed areas, ensure that appropriately-sized, clean rock is used; and that rock is installed at a similar slope to maintain a uniform bank/shoreline and natural stream/shoreline alignment

• Remove all construction materials from site upon project completion

Operation of Machinery

• Operate machinery in a manner that minimizes disturbance to the banks of the watercourse
