SCALE: 1" = 60'
1.THE EROSION AND SEDIMENT CONTROL MEASURES SHOWN ON THE DRAWINGS ARE
CONSIDERED THE MINIMUM PRACTICES NECESSARY FOR COMPLIANCE WITH THE NPDES
GENERAL PERMIT FOR STORM WATER DISCHARGES ASSOCIATED WITH CONSTRUCTION
ACTIVITY AS IDENTIFIED UNDER SECTION 327-IAC-15-5 OF THE INDIANA ADMINISTRATIVE
CODE. HOWEVER, SITE CONDITIONS, CONSTRUCTION METHODS, SEQUENCING OF WORK
AND GENERAL PRACTICE MAY WARRANT VARIATION AND/OR ADDITIONS TO THE QUANTITIES
AND LOCATIONS OF MEASURES AS SHOWN.
2.UNLESS OTHERWISE SHOWN, TEMPORARY CONTROL MEASURES SHALL BE REMOVED UPON
SATISFACTORY ESTABLISHMENT OF PERMANENT VEGETATION.
3.SEE SHEET C403 FOR DETAILS AND SPECIFICATIONS REFERENCED ON THIS SHEET.
4.PERIMETER CONTROL MEASURES (I.E. SILT FENCE, DIVERSION DITCHES, TREE PROTECTION
FENCING) SHALL BE INSTALLED PRIOR TO COMMENCING EARTHWORK ACTIVITIES.
5.IN ADDITION TO THE MAINTENANCE REQUIREMENTS IDENTIFIED FOR INDIVIDUAL MEASURES,
ALL EROSION CONTROL MEASURES INSTALLED UNDER THIS PROJECT SHALL BE INSPECTED
WEEKLY TO ENSURE THEY ARE FUNCTIONING PROPERLY. MEASURES FOUND TO BE
DEFICIENT SHALL BE REPAIRED OR REPLACED IMMEDIATELY THEREAFTER.
6.THE CONTRACTOR SHALL MAINTAIN A STABLE CONSTRUCTION ENTRANCE AT ALL TIMES AND
SHALL MAKE EFFORTS TO MINIMIZE THE ACCUMULATION OF SOIL, MUD AND DEBRIS ON
ADJOINING ROADWAYS.
7.SYMBOLS FOR INLET PROTECTION MEASURES AND DITCH CHECKS ARE SHOWN LARGER
THAN ACTUAL SIZE.
8.DISTURBED AREAS AND STOCKPILES THAT ARE TO REMAIN IDLE FOR MORE THAN 14 DAYS
SHALL BE STABILIZED WITH TEMPORARY SEEDING.
9.ADDITIONAL EROSION CONTROL MEASURES MAY BE REQUIRED BY THE INSPECTOR.
10.PORTABLE TOILETS SHALL BE ANCHORED TO THE GROUND TO PREVENT TIPPING AND
SPILLS.
THERE SHALL BE NO DIRT, DEBRIS, OR
STORAGE OF MATERIAL IN THE STREET
ADJACENT ROADS MUST BE SWEPT DAILY

1.REPAIR OR REPLACE ALL EXISTING SILT FENCE, CHECK DAMS OR INLET PROTECTION
DAMAGED DURING EARTHWORK OR CONSTRUCTION ACTIVITIES.
2.DESIGNATE THE PERSON RESPONSIBLE FOR COMPLYING WITH THE ON-SITE SWPPP
INSPECTIONS UNTIL ALL DISTURBED AREAS ON SITE SITE HAVE REACHED 70 PERCENT
VEGETATIVE COVER DENSITY.
3.IF WORK OR CONSTRUCTION HAS STOPPED FOR 2 WEEKS OR MORE BEFORE PERMANENT
SEED IS APPLIED, INSTALL TEMPORARY SEED AND MULCH AS DESCRIBED ON SHEET C403.
COORDINATE RESPONSIBILITY FOR COMPLETING THE SITE REVIEW AFTER EACH 12" RAINFALL
AND A MINIMUM OF ONE TIME A WEEK.
4.FOR ALL PHASES, COMPLETE MASS GRADING AND EXCAVATION. INSTALL ALL UTILITIES AS
INDICATED. HAUL ALL EXCESS EXCAVATION SPOILS OFFSITE.
5.THIS SITE DRAINS TO AN UNDERGROUND DETENTION SYSTEM. THE UNDERGROUND
DETENTION SYSTEM AND THE UPSTREAM AQUASWIRL STRUCTURES (3) SHALL BE INSPECTED
MONTHLY THROUGHOUT THE PROJECT CONSTRUCTION. ALL VISIBLE SEDIMENT, IF PRESENT,
SHALL BE REMOVED BY VACUUM TRUCK AFTER EACH INSPECTION.
8. COMPLETE FILL, BACKFILL, AND ROUGH GRADING REQUIRED TO RETURN ALL AREAS WITHIN
CONSTRUCTION ZONE TO SUBGRADE GRADE ELEVATION INDICATED ON PLANS. ALL FILL
MATERIAL UNDER PAVEMENT OR BUILDINGS SHALL BE APPROVED BY ON-SITE
GEOTECHNICAL ENGINEER.
9. PREPARE ALL PAVEMENT SUBGRADES PER PLANS AND SPECIFICATIONS.
10. MAINTAIN ALL INLET PROTECTION, CHECK DAMS AND SILT FENCING IN THE SITE PROJECT BY
CLEANING OUT EVERY WEEK AND AFTER EVERY RAIN EVENT OF 1/2" OR GREATER DEPTH.
11. PERFORM FINAL GRADING AND SEEDBED PREPARATION.
12. PLACE PERMANENT SEEDING AND MULCH OR EROSION CONTROL BLANKET WITHIN 30
HOURS OF SEEDBED PREPARATION. INSTALL EROSION CONTROL BLANKETS INDICATED ON
PLANS.
13. FINAL STABILIZATION IS CONSIDERED COMPLETE WHEN ALL LAND DISTURBING ACTIVITIES
HAVE BEEN COMPLETED AND A UNIFORM VEGETATED SURFACE WITH 70% DENSITY IS
ACHIEVED ON ALL DISTURBED/DENUDED AREAS AND AREAS NOT HAVING A PERMANENT
STRUCTURE. THE CONTRACTOR SHALL OVER-SEED AS REQUIRED TO OBTAIN 70 PERCENT
VEGETATIVE DENSITY IF REQUIRED.
14. AFTER SITE HAS REACHED 70% VEGETATIVE COVER, CONTRACTOR SHALL REMOVE
REMAINING TEMPORARY BMP STRUCTURES AND REPAIR AND RE-SEED ANY DISTURBED
AREAS AS REQUIRED.
15. ONCE THE CONSTRUCTION ACTIVITY IS COMPLETED (BY RULE LANGUAGE, WHEN FINAL
STABILIZATION HAS OCCURRED), A COMPLETED RULE 5 NOTICE OF TERMINATION (NOT) MUST
BE SUBMITTED TO IDEM.

NOTES:
1. ALL DISTURBED AREAS SHALL BE
STABILIZED WITH SEED AND MULCH,
SEED AND EROSION CONTROL BLANKET,
PAVEMENT OR LANDSCAPE BEDS
WHETHER INDICATED ON THESE PLANS
OR NOT.
2.SEE LANDSCAPE PLANS FOR SPECIFIC
STABILIZATION METHODS AND
MATERIALS IN PARKING LOT BEDS, AND
AREAS AROUND THE BUILDING.
