Samson Oceanfront Park <br />City of Sunny Isles <br />Technical Specifications <br />EROSION, SEDIMENTATION AND DUST CONTROL 02270-3 <br />prevent the formation of gullies or the spread of mud and debris across roads, into waterways or other <br />areas where it may be considered a nuisance. <br /> <br />3.02 <br /> <br />PLANNING OF CONSTRUCTION: <br />A. Planning and coordination of the construction is needed to minimize sediment pollution. Clearing shall <br />be kept to shortest distance possible ahead of construction. Cleared areas shall be kept to minimum <br />required to facilitate construction. <br /> <br />B. Restoration work shall be performed as the Project progresses and not be left until the end of the <br />Project. No areas shall be left unprotected for longer than 10 days without some form of temporary <br />seeding or, if during a non-growing season, some other form of stabilization, such as mulch. <br /> <br />3.03 <br /> <br />EXCAVATION AND BACKFILL: <br />A. Excavation shall be closely controlled. The material removed from the excavation shall be selectively <br />stockpiled in areas where a minimum of sediment will be generated and where other damage will not <br />result from piled earth. Drainage swales and ponds shall be protected at all times and the piling of soil <br />in drainageways shall not be allowed. Repaving shall be placed promptly following completion of <br />backfilling and compaction in improved areas. <br /> <br />3.04 <br /> <br />STOCKPILES: <br />A. Stockpile areas shall be selected and maintained by on-site personnel. Site selection and stockpile <br />design shall incorporate sediment and erosion control considerations to prevent the potential direct <br />production and delivery of sediment to waterways, and damage to vegetation. Temporary stabilization <br />of stockpiles shall be promptly instituted. The existence of critical slopes on stockpiles shall be <br />avoided. Stockpiling in or immediately adjacent to diversion channels shall not be allowed. If a <br />stockpile is to remain for over sixty (60) days, it shall be stabilized by soil stabilizing chemicals, <br />temporary vegetation, interim structures or other approved practices. <br /> <br />B. Temporary vegetative measures planned for implementation on stockpiles shall be established <br />immediately after stockpile completion. Proper mulching and soil stabilization in conjunction with <br />these seeding operations shall also be carried out. <br /> <br />3.05 <br /> <br />SILT FENCES: <br />A. Place silt fences in a continuous row, parallel to the slope, waterway, roadway or other area being <br />protected. Anchor the silt fence fabric to posts set at a minimum of 10 ft. apart. Embed the bottom of <br />the fabric a minimum of 4" deep and backfill and compact soil over the embedded portion. Replace or <br />repair any sections of fence, which collapse or are washed out during the construction period as soon <br />as reasonably possible. <br /> <br />B. Inspect all silt fences immediately after each rainfall and at least daily during prolonged rainfall. <br />Immediately correct any deficiencies. In addition, make a daily review of the location of silt fences in <br />areas where construction activities have changed the natural contour and drainage runoff to ensure that <br />the silt fences are properly located for effectiveness. Where deficiencies exist, install additional silt <br />fences as directed by the Engineer. <br /> <br />C. Remove sediment deposits when the deposit reaches approximately 1/2 of the volume capacity of the <br />silt fence or as directed by the Engineer. Dress any sediment deposits remaining in place after the silt <br />fence is no longer required to conform to the finished grade, and prepare and sod them in accordance <br />with the requirements of this section. <br /> <br />3.06 <br /> <br />SODDING:
