EROSION CONTROL NOTES
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,
TYPES, AND LOCATIONS OF BMP MEASURES AS SHOWN.
2.UNLESS OTHERWISE SHOWN, TEMPORARY CONTROL MEASURES SHALL BE REMOVED UPON
SATISFACTORY ESTABLISHMENT OF PERMANENT VEGETATION.
3.SEE SHEET C404-C405 FOR DETAILS AND SPECIFICATIONS REFERENCED ON THIS SHEET.
4.PERIMETER CONTROL MEASURES (I.E. SILT FENCE, DIVERSION DITCHES AND BERMS, 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.
1.EARTH MOVING ACTIVITIES MAY NOT BEGIN UNTIL AFTER ITEMS 2-5 HAVE BEEN COMPLETED.
2.DESIGNATE THE PERSON RESPONSIBLE FOR COMPLYING WITH THE ON-SITE SWPPP. COORDINATE
RESPONSIBILITY FOR COMPLETING THE SITE REVIEW AFTER EACH 12" RAINFALL AND A MINIMUM OF

INFORMATION FOR THE PERSON RESPONSIBLE FOR IMPLEMENTING THE SWPPP.
4.INSTALL SILT FENCE,CONSTRUCTION ENTRANCE, INLET/CULVERT PROTECTION AND CONCRETE
WASHOUT AS SHOWN ON THE PLANS. CONSTRUCT ROCK CHECK DAM SILT FENCE OPENINGS
IMMEDIATELY AFTER INSTALLING SILT FENCING. INSTALL DIVERSION CHECKS ALONG NORTH SILT
FENCE LINE AS SHOWN ON THE PLANS. INSTALL ALL TREE PROTECTION MEASURES AS SHOWN ON
THE PLANS.
5.CONTACT CARMEL ENGINEERING DEPARTMENT AT (317) 571-2441 FOR A PRE-CONSTRUCTION
CONFERENCE MEETING BEFORE BEGINNING ANY EARTHMOVING ACTIVITIES.
6.INSTALL PORT-A-LET, AND COVERED CONSTRUCTION DUMPSTER.
7.PERFORM REQUIRED SITE DEMOLITION AND CLEARING.
8.STRIP TOPSOIL AND STORE IN DESIGNATED AND PROTECTED TOPSOIL STOCKPILE AREA.
PERFORM MASS GRADING FOLLOWED BY UTILITY INSTALLATION. MAINTAIN STORM INLET
PROTECTION UNTIL SITE IS STABILIZED AND EROSION WILL NOT LIKELY OCCUR.
9.CONTRACTOR SHALL EXCAVATE WET DETENTION BASIN TO ACT AS TEMPORARY SEDIMENT BASIN
BEFORE PRECEDING WITH ANY OTHER EARTHMOVING ACTIVITIES. OVER-EXCAVATE BASIN FOR
SEDIMENT STORAGE AS INDICATED ON PLAN. MAINTAIN A STONE CHECK DAM IN FRONT OF THE
BASIN OUTLET UNTIL ENTIRE SITE HAS REACHED 70% VEGETATIVE COVER DENSITY.
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.IF WORK ON SITE WILL STOP FOR 2 WEEKS OR MORE AFTER COMPLETION OF MASS GRADING,
INSTALL TEMPORARY SEED AS INDICATED ON THIS SHEET AND SHEET C403.
12.ADDITIONAL EROSION AND SEDIMENT CONTROL MEASURES MAY BE REQUIRED BY THE INSPECTOR.
