Stockpile materials in designated staging areas. 3. Install silt fencing to the limits shown on the plans and at any other locations as directed by the Engineer. Silt fencing will be installed around the limits of all staging and stockpile areas. 4. Install safety fencing as shown on the plans and at all other locations as directed by the Engineer. PHASE 2 ROAD REMOVAL, CULVERT REMOVAL, AND DITCH FILLING (Numbered callouts and arrows on Erosion Control Sheets correspond to the following items. Arrows indicate direction of work.) 1. Remove Road 6 on northern side of FSI crossing. Remove (2) 48” CMP culverts (previously damaged) at FSI. Regrade and stabilize banks of FSI. Remove remaining section of Road 6 on southern side of FSI. 2. Remove Road 6 and Road 3B up to FSI crossing. Remove (1) 60” CPP at FSI. Regrade and stabilize banks of FSI. 3. Remove Road 3A up to the location of the (2) 48” CMP culverts located in FSI and the (1) 42” CMP culvert that connects T19 to FSI. Remove the (2) 48” CMP culverts in FSI. Regrade and stabilize banks of FSI. 4. Remove (1) 42” CMP connecting T19 and FSI, breaking any remaining connection with the upstream ditch network. Regrade and stabilize banks of FSI. 5. Remove Road 3A and fill adjacent ditch (T19) working in direction towards the intersection of Road 3A and Road 5A. 6. Remove Road 5A and fill T5 / T19 working in direction towards the intersection of Road 3A and Road 5A. Complete grading for D9. 7.
