DATUM IS ASSUMED AND PROVIDED FOR EACH SITE ON PLANS. 3. INSPECT SITE WITH FWC STAFF AND VERIFY CENTER OF PROJECT AND INTENT. MOVE CENTER OF PROJECT (+/-) 20' MAXIMUM TO FACILITATE CONSTRUCTION, IMPROVE FUNCTION OF STRUCTURE, OR DIRECTED AND APPROVED BY FWC.. CLEAR AND GRUB THE AREA OF CONSTRUCTION. STOCKPILE DEBRIS IN NEAT ROWS ALONGSIDE OF ROADWAY SHOULDER. STOCKPILE ORGANIC MATERIAL IN SEPARATE PILE FOR LATER USE. 5. INSTALL HAY BALES AS SHOWN ON PLANS AND TYPICAL SECTIONS. HAY BALES SHALL BE MAINTAINED THROUGHOUT CONSTRUCTION. SILT FENCE OR OTHER ARTIFICIAL SEDIMENT BARRIER MATERIAL IS NOT ALLOWED. 6. INSTALL STRUCTURE AS DESCRIBED. USE CLEAN MATERIAL EXCAVATED AND STOCKPILED FROM OTHER SITES FOR USE IN DITCH PLUGS. 7. AFTER STRUCTURE IS COMPLETE, INSPECTED AND APPROVED BY FWC REPRESENTATIVE, USE ORGANIC SOIL TO BACKFILL DISTURBED AREAS NOT PROTECTED BY ROCK. 8. SEED ALL DISTURBED AREAS AND COVER WITH HAY. 9. REMOVE AND SPREAD OUT HAYBALES PRIOR TO LEAVING SITE. 10. FOR DITCH BLOCKS, PLACE DEBRIS (TREES, SHRUBS, ETC.)
