Projects that have the potential to incur negative impacts to identified environmentally significant areas, natural environment parks and natural areas often require a natural site assessment.

The objectives of a BIA are to ensure adequate protection of environmentally significant areas and natural areas with ecologically diverse components and prevent and/or minimize environmental impacts.

The various types of BIAs require the expertise of a qualified environmental consultant biologist to capture the biophysical elements and outline the potential impacts and the mitigation strategies to offset the project impacts.
