BMP C162: Scheduling <br /> Purpose <br /> Sequencing a construction project reduces the amount and duration of soil exposed to <br /> erosion by wind, rain, runoff, and vehicle tracking. <br /> Conditions of Use <br /> The construction sequence schedule is an orderly listing of all major land-disturbing <br /> activities together with the necessary erosion and sedimentation control measures <br /> planned for the project. This type of schedule guides the contractor on work to be done <br /> before other work is started so that serious erosion and sedimentation problems can be <br /> avoided. <br /> Following a specified work schedule that coordinates the timing of land-disturbing <br /> activities and the installation of control measures is perhaps the most cost-effective way <br /> of 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 rainy periods. <br /> • Schedule projects to disturb only small portions of the site at any one time. <br /> Complete grading as soon as possible. Immediately stabilize the disturbed <br /> portion before grading the next portion. Practice staged seeding in order to <br /> revegetate cut and fill slopes as the work progresses. <br /> Page 153 <br />
