1 <br /> planned for the project. This type of schedule guides the contractor on work to be done 1 <br /> before other work is started so that serious erosion and sedimentation problems can be <br /> avoided. I <br /> Following a specified work schedule that coordinates the timing of land-disturbing activ- <br /> ities and the installation of control measures is perhaps the most cost-effective way of <br /> controlling erosion during construction. The removal of surface ground cover leaves a <br /> site vulnerable to accelerated erosion. Construction procedures that limit land clearing <br /> provide timely installation of erosion and sedimentation controls, and restore protective • <br /> cover quickly can significantly reduce the erosion potential of a site. <br /> Design Considerations <br /> . Minimize construction during rainyperiods. <br /> . Schedule projects to disturb only small portions of the site at any one time. Corn- I <br /> plete grading as soon as possible. Immediately stabilize the disturbed portion <br /> before grading the next portion. Practice staged seeding in order to revegetate cut <br /> and fill slopes as the work progresses. <br /> 11-4.2 Runoff Conveyance and Treatment BMPs <br /> This section contains the standards and specifications for Runoff Conveyance and Treat- <br /> ment BMPs.
