10 <br />Chapter 4-- Best Management Practices for Erosion and Sediment Control <br />4.01 IMPORTANCE OF CONSTRUCTION SEQUENCING <br />Definition <br />Coordinating. the construction scheduie to minimize the amount.of area disturbed at any <br />one time and coordinating land clearing with the installation of eros ion control. 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 find 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 iie in.place.to control <br />runoff and capture sediments. Prioritize disturbed. areas inthe 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 piecipitaiion. 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 />Specifications <br />Management of construction projects can be viewed in three phases. Ph.mse f is the initial <br />` instailation 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 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 />4-1 <br />W <br />
