Instructions:
/, Check the box to the left of ail applicable construction activity (first column) expected to occur during construction.
2. Located along the top of the BMP Table is a fist of BMP's with it's corresponding California Stormwater Quality Association (CASQA) designation number,
or more BMP"s you intend to use during construction from the list. Check the box where the chosen activity row intersects with the BMP column.
Choose one
3. Refer to the CASQA construction handbook for information and details of the chosen BMPs and how to apply them to the project.
STORM WATER POLLUTION PREVENTION NOTES
GENERAL SITE MANAGEMENT REQUIREMENTS
THE FOLLOWING GENERAL SITE MANAGEMENT REQUIREMENTS SHALL BE ADHERED TO
THROUGHOUT THE DURATION OF THE CONSTRUCTION WORK (YEAR ROUND),
7. IN CASE EMERGENCY WORK IS REQUIRED, CONTACT-QFNNl'i MA THl'i
AT (TEL.NO.) (760) 402 )4 l5
2. DEVICES SHOWN ON CITY APPROVED PLANS SHALL NOT BE MOVED OR MODIFIED
WITHOUT THE APPROVAL OF THE ENGINEERING INSPECTOR,
J, THE CONTRACTOR SHALL RESTORE ALL EROSION CONTROL DEVICES TO WORKING ORDER
TO THE SA T/SFACT/ON OF THE CITY ENGINEER AFTER EACH RUN-OFF PRODUCING RAINFALL .
4. THE CONTRACTOR SHALL INSTALL ADDITIONAL EROSION CONTROL MEASURES AS MAY BE
REQUIRED BY THE CITY ENGINEER DUE TO UNCOMPLETED GRADING OPERATIONS OR UNFORSEEN
CIRCUMSTANCES WHICH MAY ARISE.
5. THE CONTRACTOR SHALL BE RESPONSIBLE AND SHALL TAKE NECESSARY PRECAUTIONS
TO PREVENT PUBLIC TRESPASS ONTO AREAS WHERE IMPOUNDED WATERS CREA TE A HAZARDOUS
CONDITION.
6. GRADING AREAS AROUND THE PROJECT PERIMETER MUST DRAIN AWAY FROM THE FACE
OF SLOPE AT THE CONCLUSION OF EACH WORKING DAY.
7. ALL REMOVABLE PROTECTIVE DEVICES SHALL BE IN PLACE AT THE END OF EACH WORKING
DAY WHEN FIVE (5) DAY RAIN PROBABILITY FORECAST EXCEEDS FORTY PERCENT (40%}. SILT
AND OTHER DEBRIS SHALL BE REMOVED AFTER EACH RAINFALL.
8. ALL GRAVEL BAGS SHALL CONTAIN 3/4 INCH MINIMUM AGGREGATE.
9. ALL EXPOSED DISTURBED AREAS MUST HA VE EROSION PROTECTION BMPs PROPERLY
INSTALLED. THIS INCLUDES ALL BUILDING PADS, UNFINISHED ROADS, AND SLOPES.
10 ADEQUATE PERIMETER PROTECTION BMPs MUST BE INSTALLED AND MAINTAINED AND
WILL BE UPGRADED, IF NECESSARY, TO PROVIDE SUFFICIENT PROTECTION FROM RUNOFF
DURING RAIN EVENTS.
11. ADEQUATE SEDIMENT CONTROL BMPs MUST BE INSTALLED AND MAINTAINED.
12. ADEQUATE BMPs TO CONTROL OFFS/TE SEDIMENT TRACKING MUST BE INSTALLED AND
MAINTAINED,
13. A MINIMUM OF 125% OF THE MATERIAL NEEDED TOO INSTALL STANDBY BMPs TO
PROTECT THE EXPOSED AREAS FROM EROSION AND PREVENT SEDIMENT DISCHARGES,
MUST BE STORED ONSITE. AREAS ALREADY PROTECTED FROM EROSION USING PHYSICAL
STAB/LIZA T/ON OR ESTABLISHED VEGETA T/ON STAB/LIZA T/ON BMPs ARE NOT CONSIDERED
TO BE "EXPOSED" FOR PURPOSfS OF THIS REQUIREMENT.
14, THE OWNER/DEVELOPER/CONTRACTOR MUST FOLLOW ''WEATHER TRIGGERED" ACTION
PLAN AND BE ABLE TO DEPLOY STANDBY BMPs TO PROTECT THE EXPOSED PORTIONS OF
THE SITE WITHIN 48 HOURS OF A PREDICTED STORM EVENT (A PREDICTED STORM EVENT
IS DEFINED AS A 40% CHANCE OF RAIN WITHIN A 5-DA Y NATIONAL WEATHER SERVICE
FORECAST}. ON REQUEST, THE OWNER/DEVELOPER/CONTRACTOR MUST PROVIDE PROOF
OF THIS CAPABILITY.
15. DEPLOYMENT OF PHYSICAL OR VEGETATION EROSION CONTROL BMPs MUST COMMENCE
17. ALL DISTURBED AREAS THAT ARE NOT COMPLETED AND/OR NOT BEING ACTIVELY GRADED
MUST BE FULLY PROTECTED FROM EROSION IF LEFT FOR 14 OR MORE DAYS. THE ABILITY
TO INSTALL BMP MATERIALS IN A PROMPT MANNER IS NOT SUFFICIENT. BMPs NEED TO BE
INSTALLED IN THESE AREAS
/8, BMPs MUST BE STOCKPILED AT VARIOUS LOCATION THROUGHOUT THE PROJECT SITE
THROUGHOUT THE YEAR. WHENEVER THERE IS A 40% CHANCE OR GREATER OF A RAIN
WITHIN A THREE (J) DAY FORECAST, THE INSPECTOR WILL VERIFY THAT BMPs ARE
ADE QUA TEL Y STOCKPILED, BMPs MUST BE STOCKPILED AND READY FOR OEPLO YMENT WHEN /J:lf;I/lr,/i0 50% CHANCE OF RAIN WITHIN A 48 HOUR FORECAST FAILURE TO COMPLY WITH mrs 'lfl!'i!Jr:JIREMENT COULD RESULT IN THE ISSUANCE OF A STOP WORK NOTICE OR OTHER
ENFORCEMENT ACTION.
19. ALL TREATMENT AND EROSION CONTROL BMPs MUST BE INSPECTED WEEKLY AND
PRIOR TO A FORECASTED RAIN EVENT OF CREA TER THAN 50%, AND AFTER A RAIN EVENT.
IN ADDITION, TREATMENT CONTROL BMPs MUST BE SERVICED AS NEEDED THROUGHOUT
20. IF SELECTED BMP FAILS DURING A RAIN EVENT, IT MUST BE REPAIRED OR IMPROVED
OR REPLACED WITH AN ACCEPTABLE ALTERNATE AS SOON AS IT IS SAFE TO DO SO. THE
FAILURE OF A BMP IND/CA TES IT WAS NOT ADEQUATE FOR THE CIRCUMSTANCES IN WHICH
IT WAS USED, REPAIRS AND REPLACEMENT MUST THEREFORE PUT A MORE ROBUST BMP
MEASURE IN PLACE
21. ALL CONSTRUCT/ON EMPLOYEES MUST BE TRAINED ON THE IMPORTANCE OF STORM
WATER POLLUTION PREVENTION ANO BMP MAINTENANCE.
WEATHER TRIGGERED ACTION PLAN
THE DEVELOPER SHALL DEPLOY STANDBY BEST MANAGEMENT PRACTICE MEASURES TO
COMPLETELY PROTECT THE EXPOSED PORTIONS OF THE SITE WITHIN 48 HOURS OF A
PREDICTED STORM EVENT ( A PREDICTED STORM EVENT IS DEFINED AS A FORECASTED, 40%
CHANCE OF RAIN BY THE NATIONAL WEATHER SERVICE}, IN ADDITION TO BMPs IMPLEMENTED
YEAR-ROUND INCLUDING PERIMETER CONTROL, WIND EROSION CONTROL, TRACKING,
NON-STORM WATER CONTROL, WASTE MANAGEMENT, ANO MATERIALS POLLUTION CONTROL
THE NATIONAL WEATHER SERVICE FORECAST SHALL BE MONITORED AND USED BY
THE DEVELOPER ON A DAILY BASIS. IF PRECIPITATION IS PREDICTED (40% CHANCE OF
RAIN), THEN THE NECESSARY WATER POLLUTION CONTROL PRACTICES SHALL BE DEPLOYED
WITHIN 48 HOURS AND PRIOR TO THE ONSET OF THE PRECIPITATION.
THE DEPLOYMENT OF THE BMPS SHALL INCLUDE BUT NOT BE LIMITED TO GRAVEL BAGS AND
SILT FENCES A MINIMUM OF 125% OF THE MATERIAL NEEDED TO INSTALL STANDBY BEST
MANAGEMENT PRACTICES MEASURES TO PROTECT THE EXPOSED AREAS FORM EROSION AND
PREVENT SEDIMENT DISCHARGES MUST BE STORED ON-SITE. AREAS THAT HAVE ALREADY
BEEN PROTECTED FROM EROSION USING PHYSICAL STAB/LIZA TION OR ESTABLISHED
VEGETA T/ON STAB/LIZA TION BMPS AS DETERMINED BY THE CITY OF CARLSBAD ARE NOT
CONSIDERED TO BE "EXPOSED" FOR THE PURPOSES OF "WEATHER TRIGGERED ACTION PLAN".
AN ADEOUA TE SOURCE OF EQUIPMENT AND WORKERS SHALL BE AVAILABLE FOR
