SOD PREPARATION
1. REMOVE UNDESIRABLE GROUND COVERS INCLUDING ANY TEMP. SEEDING.
2. RIP THE AREA TO BE SODDED TO A MINIMUM DEPTH OF 4 - 6".
3. REMOVE ALL LOOSE ROCKS, ROOTS, ETC. LEAVING SURFACE
SMOOTH AND UNIFORM.
4. PREPARE SOD BASE PER A.A.N. STANDARDS.
5. APPLY SOD & IMMEDIATELY STAKE/FLAG OFF ALL NEW LAWN AREAS
FROM PEDESTRIAN AND VEHICLES FOR THREE (3) WEEKS.
6. IRRIGATE SODDED AREAS FOR THE THREE WEEK PERIOD.

ALL UNPAVED DISTURBED AREAS (OR LAWN TO BE RE-ESTABLISHED)
OUTSIDE PLANTING BED TO BE SODDED W1 AN EVEN MIXTURE OF KENTUCY
31, OR APPROVED EQUAL FOR REGION, SO AS TO PRODUCEA THICK, FIRM
STAND OF GRASS. DO NOT FERTILIZE SODDED AREAS. ALL AREAS TO BE
SODDED TO HAVE APPROPRIATE SOIL PREPERATIONS, SEE
SPECIFICATIONS. SOD SHALL BE OF GOOD & HEALTHY COLOR WHEN
DELIVERED. SOD SHALL BE HARVESTED & DELIVERED W/IN A PERIOD OF 36
HOURS OR PRECAUTIONS MUST BE TAKEN TO PREVENT SOD FROM DRYING
OUT WHILE IN TRANSIT.
EROSION CONTROL MAINTENANCE PLAN:
1. INSPECT ALL SEDIMENTATION & EROSION CONTROL DEVICES FOR STABILITY
AND FUNCTION EACH WEEK AND FOLLOWING EACH RAINFALL EVENT.
2. REMOVE ALL SILT/SEDIMENT FROM TEMPORARY TRAPS WHEN ACCUMULATED
VOLUME HAS REACHED 50% OF CAPACITY.
3. REMOVE ACCUMULATED SILT/SEDIMENT FROM BEHIND TEMPORARY
SEDIMENT FENCE WHEN DEPTH EXCEEDS APPROXIMATELY 0.5' REPAIR AND
REPLACE SILT FENCE AS NECESSARY.
4. SEED AND STABILIZE TEMPORARY DIVERSION BERMS IMMEDIATELY AFTER
CONSTRUCTION INCLUDING "CLEAN" WATER DIVERSION BERMS. RE -GRADE/
REPAIR BERMS AS REQUIRED.
5. CONTRACTOR SHALL APPOINT AN ONSITE INSPECTOR AND MAINTAIN
RECORDS OF INSPECTIONS IN ACCORDANCE WITH THE PROVISIONS OF THE
GENERAL NPDES STORMWATER DISCHARGE PERMIT, IF REQUIRED, FOR
CONSTRUCTION ACTIVITIES
6. ALL SEDIMENT AND EROSION CONTROL DEVICES SHALL BE INSPECTED
EVERY SEVEN (7) DAYS AND WITHIN 24 HOURS AFTER EACH RAINFALL
OCCURRENCE THAT EXCEEDS ONE-HALF (0.5) INCH, IF SITE INSPECTIONS
IDENTIFY BMPS THAT ARE DAMAGED OR NOT OPERATING EFFECTIVELY,
MAINTENANCE MUST BE PERFORMED AS SOON AS PRACTICABLE OR AS
REASONABLY POSSIBLE AND BEFORE THE NEXT STORM EVENT WHENEVER
PRACTICABLE.
