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 <br /> one 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 /> + <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 <br /> + the size , location , and complexity of the construction site . <br /> Planning Considerations <br /> + <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 <br /> runoff and capture sediments. Prioritize disturbed areas in the vicinity of water bodies , <br /> wetlands , steep grades , long slopes , etc. for effective stabilization within seven days of <br /> disturbance . Graded areas that will not be worked on should be seeded and mulched <br /> immediately, rather than waiting until all project grading is done . A well-planned and well- <br /> maintained construction entrance with stabilized construction roads can prevent offsite <br /> sedimentation , keep sediments off of roads , minimize complaints from neighbors , and <br /> reduce future expenses and aggravation . <br /> Land disturbing activities are best scheduled during periods of low precipitation . Generally, <br /> Florida's wet season occurs from May to November with a dry season from November to <br /> May. 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 1 is the initial <br /> installation of perimeter controls , sediment traps , basins , and diversions prior to site <br /> development. Phase 11 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 111 is the finished product and should <br /> perform as such . <br /> 4- 1 <br />
