Abstract
The stresses the need to study potential environmental problems and to provide conceptual design of mitigative and compensatory measures such as excavations to enhance off-channel rearing areas and instream rock placements to reduce adverse effects of stream channelization caused by river diversions and bank armoring. Some of the other factors that minimized adverse effects of construction activities included stipulation of clearing restrictions, riprapping at culverts and in drainage channels, reseeding of cut-and-fill slopes, riprapping of cut-and-fill slopes extending into the river, inclusion of specifications for environmental protection in the contract documents, use of steel-pile bridge abutments rather than concrete, and employment of environmental monitors to inspect construction activities and assist contractors in resolving environmental problems. An environmental coordinator employed by the Highway Ministry maintained a good liaison between the consultants, the regulatory agencies, and the highway design engineers during the planning and design stages, and it is suggested that he or another senior employee should also have been assigned full responsibility to coordinate environmental protection during the construction stage.
