SEEDBED PREPARATION NOTES:
1. SURFACE WATER CONTROL MEASURES TO BE INSTALLED ACCORDING TO PLAN.
2. AREAS TO BE SEEDED SHALL BE RIPPED AND SPREAD WITH AVAILABLE
TOPSOIL 3" DEEP. TOTAL SEEDBED PREPARATION DEPTH SHALL BE 4' -6" DEEP.
3. LOOSE ROCKS, ROOTS AND OTHER OBSTRUCTIONS SHALL BE REMOVED FROM THE
SURFACE SO THAT THEY WILL NOT INTERFERE MATH THE ESTABLISHMENT AND
MAINTENANCE OF VEGETATION. SURFACE FOR FINAL SEEDBED PREPARATION,
AT FINISH GRADES SHOWN, SHALL BE REASONABLY SMOOTH AND UNIFORM.
4. IF NO SOIL TEST IS TAKEN, FERTILIZER AND LIME TO BE ACCORDING TO SEEDING
SPECIFICATIONS ABOVE. IN ADDITION, PROVIDE 15 LBS/1000 S.F. OF SUPER
PHOSPHATE.
5. IF SOIL TEST IS TAKEN, PROVIDE LIME AND FERTILIZER ACCORDING TO SOIL TEST
REPORT.
6. LIME AND FERTILIZER SHALL BE APPLIED UNIFORMLY AND MIXED WITH THE SOIL
DURING SEEDBED PREPARATION.
CONSTRUCTION SEQUENCE OF EACH SECTION
1. OBTAIN PLAN APPROVAL.
2. INITIATE CLEARING & INSTALL CONSTRUCTION ENTRANCE, GRAVEL, & RIP -RAP FILTER BASINS,
& INTERCEPTOR DIKES ADJACENT TO DITCH.
3. BEGIN STRIPPING SITE & EARTHWORK. INSTALL ROCK DAMS & SEDIMENT TRENCHES IMMEDIATELY
UPON OPENING OF ENTRANCE, ALSO INSTALL CONSTRUCTION ENTRANCE.
4. INSTALL CULVERT, MAINTAINING FLOW IN EXISTING CHANNEL. UPON COMPLETION, INSTALL U.S. &
D.S. RIP -RAP & BEGIN PLACING FILL OVER PIPE. ELIMINATE INTERCEPTOR DIKES.
5. MAINTAIN STRUCTURES DURING CONSTRUCTION.
6. STABILIZE SLOPES & DITCHES AS THEY ARE BROUGHT TO GRADE.
7. REMOVE TEMPORARY MEASURES.
