Chapter 4 - Best Management Practices for Erosion and Sediment Control <br /> 4 . 01 IMPORTANCE OF CONSTRUCTION SEQUENCING <br /> Definition <br /> Coordinating the construction schedule to minimize the amount. of area disturbed at any one <br /> time and coordinating land clearing with the installation of erosion control measures . <br /> Purpose <br /> To minimize the amount of disturbed area , thereby reducing erosion potential . <br /> Condition where Practice Applies <br /> This practice applies to all construction projects . The level of planning and management <br /> necessary to minimize erosion and control sedimentation adequately is dependent upon the <br /> size , location , and complexity of the construction site. "r <br /> Planning Considerations <br /> The key to efficient and cost-effective erosion control is to plan construction activities in <br /> phases to reduce the erosion potential of the site . By clearing only areas that are to be <br /> developed , only limited areas of land are disturbed , making it much easier to prevent and <br /> control erosion than if the entire site were exposed at once . On larger projects sub-phases <br /> should be used to minimize the area of exposed soil . Before site disturbance occurs <br /> perimeter controls , sediment traps , basins , and diversions should be in place to control runoff <br /> and capture sediments . Prioritize disturbed areas in the vicinity of water bodies , wetlands , <br /> steep grades , long slopes , etc , for effective stabilization within seven days of disturbance . <br /> Graded areas that will not be worked on should be seeded and mulched immediately, rather <br /> than waiting until all project grading is done . Awell -planned and well-maintained construction <br /> entrancewith stabilized construction roads can preventoffsite sedimentation , keep sediments <br /> off of roads , minimize complaints from neighbors , and reduce future expenses and <br /> aggravation . <br /> Land disturbing activities are best scheduled during periods of low precipitation . Generally, <br /> Florida's wet season occurs from Mayto Novemberwith a dry season from Novemberto May. <br /> Check with your local Water Management District (WMD) or Florida Department of <br /> Transportation ( FDOT) office for more precise information in your area . <br /> Specifications ■ <br /> Management of construction projects can be viewed in three phases. Phase / is the initial <br /> installation of perimeter controls , sediment traps , basins, and diversions prior to site <br /> development. Phase /I is an interim stormwater management plan whereby components of <br /> the permanent stormwater management system are constructed and connected to the <br /> stormwater facilities as the site is developed . Phase /// is the finished product and should <br /> perform as such . <br /> 4A <br /> r <br />
