CONSTRUCTION SEQUENCE
1• OBTAIN ALL NECESSARY PERMIT APPROVALS PRIOR TO ANY LAND DISTURBING ACTIVITY.
2. HOLD A PRE -CONSTRUCTION MEETING WITH THE EROSION CONTROL INSPECTOR.
3. INSTALL GRAVEL CONSTRUCTION ENTRANCE, COMMENCE CLEARING AND ROUGH GRADING
OPERATIONS TO ESTABLISH TEMPORARY DIVERSION SWALES, SEDIMENT TRAPS, AND BASINS.
4. ROUGH GRADE ROADWAY AND SITE.
5. INSTALL STORM DRAINAGE SYSTEM WITH INLET PROTECTION DEVICES.
6. CONSTRUCT UNDERGROUND UTILITIES (WATER AND SANITARY SEWER).
7. PROVIDE TEMPORARY PROTECTION MEASURES AND DEVICES AS REQUIRED UNTIL
UNDERGROUND UTILITIES AND PAVEMENT SECTION IS COMPLETE AND FINAL GRADES ARE
STABILIZED WITH TEMPORARY VEGETATIVE COVER,
8. STABILIZE gFERTILIZE, SEED, AND MULCH) ALL DISTURBED AREAS AS SOON AS FINAL GRADES
ARE ESTA1t�s�LISHED.
9• OTENMNORARYEROSION ICONTTROL MEASURES• RDISTURBED
MOVE S EDIMENT FROM STABILIZED REMOVE
AND
RESTORE TO ORIGINAL DIMENSIONS.
SEEDBED PREPARATION
1• CHISEL COMPACTED AREAS AND SPREAD TOPSOIL 3 INCHES DEEP OVER
ADVERSE SOIL CONDITIONS, IF AVAILABLE.
2. RIP THE ENTRANCE AREA TO 6 INCHES DEPTH.
3. REMOVE ALL LOOSE ROCK, ROOTS, AND OTHER OBSTRUCTIONS LEAVING
SURFACE REASONABLY SMCDTH AND UNIFORM.
4. APPLY AGRICULTURAL LIME, FERTILIZER, AND SUPER PHOSPHATE
UNIFORMLY AND MIX WITH SOIL (SEE BELOW*).
5. CONTINUE TILLAGE UNTIL A WELL - PULVERIZED, FIRM, REASONABLY
UNIFORM SEEDBED IS PREPARED 4 TO 6 INCHES DEEP.
6. SEED ON A FRESHLY PREPARED SEEDBED AND COVER SEED LIGHTLY
WITH SEEDING EQUIPMENT OR CULTIPACK AFTER SEEDING.
7. MULCH IMMEDIATELY AFTER SEEDING AND ANCHOR MULCH.
8. INSPECT ALL SEEDED AREAS AND MAKE NECESSARY REPAIRS OR
RESEEDINGS WITHIN THE PLANTING SEASON, IF POSSIBLE. IF STAND
SHOULD BE OVER 60% DAMAGED, REESTABLISH FOLLOWING ORIGINAL
LIME, FERTILIZER AND SEEDING RATES.
9. CONSULT CONSERVA-ION INSPECTOR ON MAINTENANCE TREATMENT AND
FERTILIZATION AFTER PERMANENT COVER IS ESTABLISHED.
* APPLY; AGRICULTURAL LIMESTONE - 2 TONS/ACRE
FERTILIZER -•- 1000 LBS 'ACRE (10--10-10)
SUPER PHOSPHATE - 500 LBS/ACRE (20%)
MULCH - 2 TONS/ACRE (SMALL GRAIN STRAW)
ANCHOR - ASPHALT EMULSION AT 450 GAL
EROSION CONTROL NOTES
1. ANY GRADING BEYOND THE DENUDED LIMITS SHOWN ON THE PLAN IS A
VIOLATION OF THE COUNTY EROSION CONTROL ORDINANCE AND IS
SUBJECT TO A FINE. LIMITS OF CONSTRUCTION - 14.4 ACRES.
2. GRADING MORE THAN ONE ACRE WITHOUT AN APPROVED EROSION
CONTROL PLAN IS A VIOLATION OF THE COUNTY EROSION CONTROL
ORDINANCE AND IS SUBJECT TO A FINE.
3, STABILIZATION IS THE BEST FORM OF EROSION CONTROL. TEMPORARY
SEEDING IS NECESSARY TO ACHIEVE EROSION CONTROL ON LARGE
DENUDED AREAS AND ESPECIALLY WHEN SPECIFICALLY REQUIRED AS
PART OF THE CONSTRUCTION SEQUENCE SHOWN ON THE PLAN. ALL
GRADED SLOPES MUST BE SEEDED AND MULCHED WITHIN 15 DAYS OF
COMPLETION OF GRADING. STABILIZE AREAS OTHER THAN SLOPES WITHIN
30 WORKING DAYS OR 120 CALENDAR DAYS, WHICHEVER IS SHORTER.
4. ADDITIONAL MEASURES TO CONTROL EROSION AND SEDIMENT MAY BE
REQUIRED BY A REPRESENTATIVE OF THE COUNTY ENGINEERING
DEPARTMENT.
5- SLOPES SHALL BE GRADED NO STEEPER THAN 3:1.
6. ADDITIONAL DEVICES MAY BE REQUIRED AS AGREED UP ON FIELD
INSPECTOR, ENGINEER, AND OWNER.
7, IF ACTIVE CONSTRUCTION CEASES IN ANY AREA FOR MORE THAN 30
DAYS, ALL DISTURBED AREAS MUST BE SEEDED, MULCHED, AND TACKED
UNLESS WRITTEN APPROVAL IS GRANTED BY THE EROSION CONTROL
OFFICER.
8. FOLLOWING EVERY RAINFALL EVENT, CONTRACTOR SHALL INSPECT AND
REPAIR, AS NECESSARY, ALL DAMAGED EROSION CONTROL MEASURES.
EROSION CONTROL MAINTENANCE PLAN
1. ALL EROSION AND SEDIMENT CONTPOL PRACTICES WILL BE CHECKED FOR
STABILITY AND OPERATION FOLLOWING EVERY RUNOFF - PRODUCING
RAINFALL BUT IN NO CASE LESS THAN ONCE EVERY WEEK. ANY NEEDED
REPAIRS WILL BE MADE IMMEDIATELY TO MAINTAIN ALL PRACTICES AS
DESIGNED.
2. THE SEDIMENT TRAPS SHALL BE CLEANED OUT WHEN 1/2 FULL. GRAVEL
WILL BE CLEANED OR REPLACED WHEN THE SEDIMENT POOL NO LONGER
DRAINS PROPERLY.
3. SEDIMENT WILL BE REMOVED FROM BEHIND THE SEDIMENT FENCE WHEN
IT BECOMES ABOUT 0.5 FEET DEEP AT THE FENCE. THE SEDIMENT
FENCE WILL BE REPAIRED OR REPLACED AS NECESSARY TO MAINTAIN A
BARRIER.
ALL AREAS WILL BE FERTILIZED, RESEEDED AS NECESSARY, AND
MULCHED ACCORDING TO SPECIFICATIONS IN THE VEGETATIVE PLAN TO
MAINTAIN A VIGOROUS, DENSE VEGETATIVE COVER.
4.
GRAVEL CONSTRICTION ENTRANCE TO BE CLEANED WHEN SEDIMENT
ACCUMULATIONS ARE VISIBLE OR SEDIMENT IS DEPOSITED ON THE
ASPHALT AND STONE WILL BE PERIODICALLY TOP DRESSED WITH 2
5' INCHES OF #4 STONE TO MAINTAIN 6 INCH DEPTH.
GRADING NOTES
I. INITIATE EROSION CONTROL SEQUENCE BEFORE BEGINNING
CLEARING AND GRADING OPERATIONS.
2, CLEAR AREAS TO BE GRADED OF ALL VEGETATION, PROTECT
VEGETATION BEYOND GRADING LIMIT'S.
3. STRIP TOPSOIL TO FULL DEPTH IN AREAS TO BE GRADED AND
STOCKPILE.
4. COMPACT ALL FILL AREAS TO 95% OF MAXIMUM DENSITY.
5, ALL BANKS AND SWALE SIDE SLOPES SHALL BE GRADED
WITH NO GREATER THAN 3:1 SLOPES.
6. ALL AREAS ARE TO BE GRADED SO THAT NO AREAS OF
STANDING WATER OCCUR.
7. PROPOSED SPOT ELEVATIONS ARE SHOWN AT FINISHED
GRADE.
S. OPERATOR SHALL FIELD VERIFY EXISTING TOPOGRAPHY IN
RELATION TO THE PROPOSED GRADES TO ENSURE DRAINAGE
IN THE DIRECTIONS INDICATED ON THE PLAN.
