Chapter 4- - Best Management Practices for Erosion and Sediment Control <br /> Olin <br /> 4, 01 IMPORTANCE OF CONSTRUCTION SEQUENCING <br /> Definition <br /> Coordinating the construction schedule to minimize the amount. ofarea disturbed at any <br /> one time and coordinating land clearing with the installation of erosIon ccontrol .measures . <br /> Purpose <br /> To minimize the amount of disturbed area, thereby reducing erosion potential. <br /> ` Conditio•n 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 <br /> the size, location , and complexity of the construction site. <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. onlyareas 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 t6 minimize the. area of exposed , soil: Before site dlStUrbance occurs <br /> perimeter controls , sediment traps, basins, and diversions should lie in . place. to control <br /> runoff and capture sediments . Prioritize disturbed . areas im1he vic nity:.of water bodies, <br /> wetlands ; steep grades , long slopes, etc: fpr effective stabilization within seven days <br /> - 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. Aweii planned and well- <br /> " maintained construction entranoe ,with stabilized. constructlon . roads : wrn prevent offsite <br /> sedimentatibn , keep sediments off of roads ; minimize complaints from neighbors, and <br /> reduce future expenses and aggravation . <br /> r ' <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 focal Water Management DistriO ('WMD) or Fiorida Department of <br /> Transportation (FDOT) office for more precise information in your area. <br /> ­ <br /> Management <br /> Specifications <br /> Management of construction projects can be viewed in three phases, Ph.mse f is the initial <br /> ` installation of perimeter controls, sediment traps ; basins , and' diversions"prior to site <br /> development. Phase f/ is an interim stormwater management plan whereby components of <br /> the permanent stonrnvater 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 /> r <br /> 4-1 <br />
