<br />PGSF WMVD Storm and Combined Sewer - Construction Package 2 Erosion and Sedimentation Control <br />Project No. 180162 31 25 00 - 13 <br /> <br />F. Submit a separate Final TESC Plan for erosion control and BMP measures that will <br />remain in place after completion of construction, and indicate temporary measures that <br />will be removed. Install permanent erosion control measures and final landscaping as <br />soon as practical after final earthwork activities have been completed within a specific <br />area of Work. <br />G. Submit the TESC Plan and receive a review action of “1” or “2” per 01 33 00 prior to <br />commencement of Work. <br />H. Install perimeter protection prior to clearing and grubbing. <br />I. Construct erosion and sediment control BMPs prior to commencing trenching, cut and fill, <br />or other earthwork activity. <br />3.03 SITE PREPARATION <br />A. Prior to clearing, demolition below grade, excavation, and placement of fill; install <br />clearing limits fences, perimeter silt fences, temporary stabilized construction entrance <br />and perimeter control. <br />B. Prepare Site for surface water to flow away from excavations and disturbed soils. <br />C. Sediment control BMPs (sediment tanks, traps, diversion dikes, berms, etc) shall be <br />constructed as a first step in grading. These BMPs shall be functional before other land <br />disturbing activities take place. <br />D. The boundaries of the clearing/construction limits indicated on the Drawings shall be <br />clearly marked in the field by a continuous length of high visibility fencing. <br />1. No disturbance beyond the clearing limits shall be permitted. <br />2. Maintain the clearing limit fencing for the duration of construction. <br />E. Protect storm drainage inlets to drainage system from sediment influx by installing and <br />maintaining inlet protection. <br />F. In preparation of paving, clean all catch basins and conveyance lines. The cleaning <br />operation shall not flush sediment-laden water into the downstream system. <br />G. Prepare any permanent flow control facilities that will be used as a temporary settling <br />basin with the necessary erosion control measures and provide adequate storage <br />capacity. <br />3.04 INSTALLATION <br />A. Soils and Slopes <br />1. If soil stockpiles (imported or native) are placed on or along a street Right-of-Way, <br />these shall be covered with plastic at all times when not being actively worked, use <br />hold-downs where appropriate. <br />2. Any areas of exposed soils (i.e. excavated areas, spoil piles and imported or stored <br />fill) that will not be disturbed for two days during the wet season or seven days during <br />the dry season shall utilize approved erosion control BMP methods to prevent turbid <br />runoff into surface waters.
