These general practices have been collected from multiple DOTs and from requirements
by federal land management agencies to protect the environment in the course of
- Select the right equipment for the job.
Establish an emergency notification program.
- Before beginning a project, conduct an on-site meeting. At a minimum, include
team members with vegetation, local climate, and soils knowledge.
- Avoid earthwork in saturated soils. When possible, schedule heavy equipment
work during periods of low precipitation.
Develop and implement BMPs for mobile operations common to the construction of a
project as well as the earthwork: include asphalt recycling, concrete mixing, crushing
and the storage of materials, as appropriate to control the individual situations
these mobile operations can create.
Inspect project work daily.
- Consider the following often overlooked erosion and sedimentation control areas:
- Round the top edge of a slope failure, which is often a vertical face. For project
success, it is critical to address this "initiation point" or persistent
source of erosion by removing or rounding off the slope overhang.
- Smooth all eroding areas such as rills or gullies. In addition, prepare a seed
bed by slightly roughening Do this by raking across the slope face, not downhill.
- Create terraces when slopes exceed 35 percent. Dig these terraces
10 to 14 inches deep across the slope face. Horizontal spacing usually varies from
14 to 10 feet depending on conditions. The steeper the slope, the closer the terraces
should be to one another. The objective is to accelerate establishment of plants
by reducing the slope angle of the planted locations.
