Since environmental impacts from road development are quite common, such projects usually call for comprehensive environmental assessment studies, carried out by Environmental Assessment (EA) professionals (both specialists and generalists) who support the main engineering team. Substantial time and effort is often required to identify potential impacts and options for minimizing them, to consult with various groups who have an interest in the project, and to develop and implement mitigation
