RIPRAP NOTE: RIPRAP DU CLASS I (OR EQUIVALENT) REQUIRED, 12" DEPTH AS SHOWN ON SHEET 5 FOR PRIMARY SPILLWAY AND DEPTH AS SHOWN ON SHEET 5 FOR ROCK CHECK DAMS. NON-WOVEN FILTER FABRIC IS REQUIRED BENEATH ROCK RIPRAP IN PRIMARY SPILLWAY LOCATION AND ROCK CHECK DAM LOCATIONS AND SHALL BE SECURED TO SLOPES AND BOTTOM USING PINS AS NOTED IN SPECIFICATION 305. RIPRAP SUPPLY SOURCE SHALL BE IDENTIFIED ON-SITE DURING THE PRE-CONSTRUCTION MEETING. THERE ARE MULTIPLE EXISTING ROCK PILES ON-SITE; CONTRACTOR TO UTILIZE EXISTING ROCK PILES FOR SPILLWAY. SEE SHEET 2 FOR ADDITIONAL NOTES. MULCHING NOTE: CONTRACTOR TO APPLY STRAW MULCH TO ALL DISTURBED AREAS RECEIVING SEED (SEEDING TO BE DONE BY DUCKS UNLIMITED PRIOR TO MULCHING) AND/OR AS DIRECTED BY THE DU FIELD REPRESENTATIVE AT A RATE OF 2 TONS/ACRE. CONTRACTOR TO UNIFORMLY COVER SEEDED AREAS WITH MULCH WITHIN 24 HOURS AFTER SEEDING HAS BEEN INITIATED. CONTRACTOR SHALL ALSO ANCHOR MULCH INTO TOPSOIL AFTER SEEDING IS INITIATED. SEE CONSTRUCTION SPECIFICATION 402 AND CONSTRUCTION NOTES ON SHEET 2 FOR ADDITIONAL DETAILS.
