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 EMERGENCY WORK IS REQUIRED, CONTACT: PETER &-SUNNY LO
FROM: ARIZONA AT (TEL.NO.) 480-657-8540
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 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 CREATE 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 HAVE 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 OFFSITE 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 STABILIZATION OR
ESTABLISHED VEGETATION STABILIZATION BMPs ARE NOT CONSIDERED TO
BE "EXPOSED" FOR PURPOSES 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-DAY 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 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 HAVE 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 NOT 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.
TEMPORARY. EROSION CONTROL

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, AND 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-Sl,TE. AREAS THAT HAVE. ALREADY BEEN PROTECTED FROM
EROSION USING PHYSICAL STABILIZATION OR ESTABLISHED VEGETATION STABILIZATION BMPS AS
DETERMINED BY THE CITY OF CARLSBAD ARE NOT CONSIDERED TO BE "EXPOSED" FOR THE
PURPOSES OF "WEATHER TRIGGERED ACTION PLAN". AN ADEQUATE SOURCE OF EQUIPMENT AND
WORKERS SHALL BE AVAILABLE FOR DEPLOYMENT OF "WEATHER TRIGGERED BMPS".
OWNER'S CERTIFICATE
I UNDERSTAND AND ACKNOWLEDGE THAT I MUST: (1) IMPLEMENT BEST MANAGEMENT
PRACTICES (BMPs) DURING CONSTRUCTION ACTIVITIES TO THE MAXIMUM EXTENT
PRACTICABLE TO AVOID THE MOBILIZATION OF POLLUTANTS SUCH AS SEDIMENT AND
TO AVOID THE EXPOSURE OF STORM WATER TO CONSTRUCTION RELATED
POLLUTANTS; ANb (2) ADHERE TO, AND AT ALL TIMES, COMPLY WITH THIS CITY
