TIER 2 CITY STORM WATER POLLUTION PREVENTION PLAN (TIER 2 SWPPP)
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).
1. IN CASE EMFRr.FNCY W{JRK IS REQUIRED, CONTACT.~ Cameron Gonzales FROM: Prescott Companies
AT {TEL.NO.} 760-419-0609
2. DEVICES SHOWN ON CITY APPROVED PLANS SHALL NOT BE MOVED OR MODIFIED
WITHOUT THE APPROVAL OF THE ENGINEERING INSPECTOR.
3. THE CONTRACTOR SHALL RESTORE ALL EROSION CONTROL DEVICES TO WORKING ORDER
TO THE SATISFACTION 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 UNFDRSEEN
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 MAIN TA/Nm 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 TION OR ESTABLISHED VEGETATION STAB/LIZA TION BMPs ARE NOT CONSIDERED
TO BE "EXPOSED" FOR PURPOSES OF THIS REQUIREMENT.
14. THE OWNER/DEVELOPER/CONTRACTOR MUST FOLLOW "M"A THER 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 4D% CHANCE OF RAIN WITHIN A 5-DA Y NATIONAL M"A THER SERVICE
FORECAST). ON REQUEST, THE OWNER/DEVELOPER/CONTRACTOR MUST PROVIDE PROOF
OF THIS CAP AB/LI TY.
15. DEPLOYMENT OF PHYSICAL OR VEGETATION EROSION CONTROL BMPs MUST COMMENCE
AS SOON AS SLOPES ARE COMPLETED. THE OWNER/DEVELOPER/CONTRACTOR MAY NOT RELY
ON THE ABILITY TO DEPLOY STANDBY BMP MATERIALS TO PREVENT EROSION OF SLOPES THAT
HA VE BEEN COMPLETED.
16. THE AREA THAT CAN BE CLEARED, GRADED, AND LEFT EXPOSED AT ONE TIME IS
LIMITED TO THE AMOUNT OF ACREAGE THAT THE CONTRACTOR CAN ADEQUATELY PROTECT
PRIOR TO A PREDICTED RAIN EVENT. FOR LARGER SITES, GRADING SHOULD BE PHASED.
IT MAY BE NECESSARY TO DEPLOY EROSION AND SEDIMENT CONTROL BMPs IN AREAS THAT
ARE NOT COMPLETED, BUT ARE NOT ACTIVELY BEING WORKED BEFORE ADDITIONAL GRADING
IS ALLOWED TO PROCEED, AT THE DISCRETION OF THE CITY INSPECTOR.
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 11QI SUFFICIENT. BMPs NEED TO BE
INSTALLED IN THESE AREAS.
18. 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 (3) DAY FORECAST, THE INSPECTOR WILL VERIFY THAT BMPs ARE
ADEQUATELY STOCKPILED. BMPs MUST BE STOCKPILED AND READY FOR DEPLOYMENT WHEN
THERE IS 50% CHANCE OF RAIN WITHIN A 48 HOUR FORECAST. FAILURE TO COMPLY WITH
THIS REQUIREMENT 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 GREATER THAN 50%, AND AFTER A RAIN EVENT.
IN ADDITION, TREATMENT CONTROL BMPs MUST BE SERVICED AS NEEDED THROUGHOUT
THE YEAR.
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 INDICATES 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 CONSTRUCTION EMPLOYEES MUST BE TRAINED ON THE IMPORTANCE OF STORM
WATER POLLUTION PREVENTION AND 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 MEA THER SERVICE), IN ADDITION TO BMPs IMPLEMENTED
YEAR-ROUND INCLUDING PERIMETER CONTROL, WIND EROSION CONTROL, TRACKING,
NON-STORM WATER CONTROL, WASTE MANAGEMENT, AND MATERIALS POLLUTION CONTROL.
THE NATIONAL MEA THER 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 OEPLOYEO
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 STABILIZATION OR ESTABLISHED
VEGETATION STAB/LIZA TION BMPS AS DETERMINED BY THE CITY OF CARLSBAD ARE NOT
CONSIDERED TO BE "EXPOSED" FOR THE PURPOSES OF "M"A THER TRIGGERED ACTION PLAN".
AN ADEQUATE SOURCE OF EQUIPMENT AND WORKERS SHALL BE AVAILABLE FOR
DEPLOYMENT OF "WEATHER TRIGGERED BMPS~
EROSION CONTROL H'fDROSEEDING, PLANTING AND /RR/GA TION
1. ALL PERMANENT AND TEMPORARY EROSION CONTROL PLANTING ANO IRRIGATION SHALL
BE INSTALLED AND MAINTAINED AS REQUIRED IN SECTION 212 OF THE STANDARD
SPECIF/CATIONS AND THE FOLLOWING:
A H'fDROSEEDING SHALL BE APPLIED TO:
I ALL SLOPES THAT ARE GRADED 6: 1 {HORIZONTAL TO VERTICAL) OR

COVERAGE OF GRADING SLOPES {90% COVERAGE) PRIOR TO OCTOBER 1, THE SLOPES SHALL
BE STABILIZED BY AN APPROPRIATE EROSION CONTROL MA TT/NG MATERIAL APPROVED BY
THE PUBLIC WORKS INSPECTOR.
4. LANDSCAPING SHALL BE ACCOMPLISHED ON ALL SLOPES AND PADS AS REQUIRED BY
THE CITY OF CARLSBAD LANDSCAPE MANUAL, THE LANDSCAPING PLANS FOR THIS PROJECT
OR AS DIRECTED BY THE CITY ENGINEER OF PLANNING DIRECTOR.
