STORM WATER POLLUTION PREVENTION
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 A L C,ER DA FROM
AJI L F AT (7bo) Lilt?· 10 "7 ~ .
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 UNFORESEEN CIRCUMSTANCES WHICH MAY ARISE.
S. THE CONTRACTOR SHALL BE RESPONSIBLE AND SHALL TAKE NECESSARY
PRECAUTIONS TO PREVENT PUBLIC TRESPASS ONTO AREAS WHERE
IMPOUNDED WATERS CREATE A HAZARDOUS CONDITION .
6. GRADED 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 THE FIVE (S) DAY RAIN PROBABILITY FORECAST
EXCEEDS FORTY PERCENT (40%). SILT AND OTHER DEBRIS SHALL BE
REMOVED AFTER EACH RAINFALL.
8. ALL GRAVEL BAGS SHALL BE BURLAP TYPE WITH 3/4 INCH MINIMUM
AGGREGATE.
9. ALL GRADED AREAS MUST HAVE EROSION CONTROL PROTECTION BEST
MANAGEMENT PRACTICE MEASURES PROPERLY INSTALLED.
1 o. ADEQUATE PERIMETER PROTECTION BEST MANAGEMENT PRACTICE
MEASURES MUST SE INSTALLED AND MAINTAINED.
11. ADEQUATE SEDIMENT CONTROL BEST MANAGEMENT PRACTICE MEASURES
MUST BE INSTALLED AND MAINTAINED.
12. ADEQUATE MEASURES TO CONTROL OFFSITE SEDIMENT TRACKING MUST BE
INSTALLED AND MAINTAINED.
13. A MINIMUM OF 12S% OF THE MATERIAL NEEDED TO INSTALL STANDBY BEST
MANAGEMENT PRACTIVE MEASURES 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 MEASURES ARE NOT
CONSIDERED TO BE "EXPOSED" FOR PURPOSES OF THIS REQUIREMENT.
Standard Construction SWPPP Notes 3/24/08

•
14. THE OWNER/DEVELOPER/CONTRACTOR MUST HAVE AN APPROVED "WEATHER
TRIGGERED" ACTION PLAN AND BE ABLE TO 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). ON REQUEST, THE
OWNER/CONTRACTOR MUST PROVIDE PROOF OF THIS CAPABILITY THAT IS
ACCEPTABLE TO THE CITY.
15. DEPLOYMENT OF PHYSICAL OR VEGETATION EROSION CONTROL MEASURES
MUST COMMENCE AS SOON AS SLOPES ARE COMPLETED. THE
OWNER/CONTRACTOR MAY NOT CONTINUE TO RELY ON THE ABILITY TO
DEPLOY STANDBY BEST MANAGEMENT PRACTICE MATERIALS TO PREVENT
EROSION OF SLOPES THAT HAVE BEEN COMPLETED.
16. UNLESS OTHERWISE SPECIFIED ON THE GRADING PLANS OR THE
CONSTRUCTION STORM WATER POLLUTION PREVENTION PLAN DOCUMENTS,
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 RAINSTORM. IT MAY BE
NECESSARY TO DEPLOY EROSION AND SEDIMENT CONTROL BEST
MANAGEMENT PRACTICE MEASURES IN AREAS THAT ARE NOT COMPLETED
AND ARE NOT ACTIVELY BEING WORKED BEFORE ADDITIONAL GRADING IS
ALLOWED TO PROCEED, AT THE DISCRETION OF THE PUBLIC WORKS
INSPECTOR.
RAINY SEASON SITE MANAGEMENT REQUIREMENTS (OCTOBER 1 -APRIL 30)
THE FOLLOWING RAINY SEASON SITE MANAGEMENT REQUIREMENTS SHALL BE
ADHERED TO THROUGHOUT THE RAINY SEASON DEFINED AS BEGINNING ON
OCTOBER 1 OF ANY YEAR AND EXTENDING THROUGH APRIL 30TH OF THE FOLLOWING
YEAR:
1. EROSION CONTROL, PERIMETER PROTECTION AND SEDIMENT CONTROL BEST
MANAGEMETN PRACTICE MEASURES MUST BE UPGRADED IF NECESSARY TO
PROVIDE SUFFICIENT PROTECTION FOR STORMS LIKELY TO OCCUR DURING THE
RAINY SEASON.
2. EQUIPMENT AND WORKERS FOR EMERGENCY WORK SHALL BE MADE AVAILABLE
AT ALL TIMES DURING THE RAINY SEASON. ALL NECESSARY MATERIALS SHALL BE
STOCKPILED ON SITE AT CONVENIENT LOCATIONS TO FACILITATE RAPID
CONSTRUCTION OF TEMPORARY DEVICES WHEN RAIN IS EMINENT.
3. ADEQUATE PHYSICAL OR VEGETATION EROSION CONTROL BEST MANAGEMENT
PRACTICE MEASURES MUST BE INSTALLED AND ESTABLISHED FOR ALL
COMPLETED SLOPES PRIOR TO THE START OF THE RAINY SEASON. THESE BEST
MANAGEMENT PRACTICE MEASURES MUST BE MAINTAINED THROUGHOUT THE
RAINY SEASON. IF A SELECTED BEST MANAGEMENT PRACTICE MEASURE FAILS, IT
MUS'T BE REPAIRED AND IMPROVED, OR REPLACED WITH AN ACCEPTABLE
ALTERNATE AS SOON AS IT IS SAFE TO DO SO. THE FAILURE OF A BEST
MANAGEMENT PRACTICE MEASURE INDICATES IT WAS NOT ADEQUATE FOR THE
CIRCUMSTANCES IN WHICH IT WAS USED. REPAIRS OR REPLACEMENTS MUST
THEREFORE PUT A MORE ROBUST BEST MANAGEMENT PRACTICE MEASURE IN
PLACE.

CONTROL AND SEDIMENT CONTROL BEST MANAGEMENT PRACTICE MEASURES
PRIOR TO A PREDICTED RAINSTORM.
6. A DISTURBED AREA THAT IS NOT COMPLETED BUT THAT IS NOT BEING ACTIVELY
GRADED MUST BE FULLY PROTECTED FROM EROSION IF LEFT FOR 10 OR MORE
DAYS. THE ABILITY TO DEPLOY STANDBY BEST MANAGEMENT PRACTICE MEASURE

BMP Selection:
The following tables are provided to help identify and select appropriate site specific BMPs for
the proposed project. Review the list of potential site construction activities and site conditions
described along the left hand column of each sheet. Then, for each activity or site condition that
is included in the proposed project, pick one or more of the BMPs described at the top of the
form and place an Xes) in the box(es) that formes) an intersection between the activity/site
condition row and BMP column(s).
All structural (physical facility) BMP's should be shown on the site plan in the Construction
SWPPP drawing set. Any proposed no-structural BMP should be noted in the Special Notes on

BMP Objectives
o Soil Stabilization
o Sediment Control
o Tracking Control
o Wind Erosion Control
• Non-Storm Water Management
• Materials and Waste Management
Definition and Procedures and practices to minimize or eliminate the discharge of construction
Purpose site sanitary/septic waste materials to the storm drain system or to watercourses.
Appropriate Sanitary/septic waste management practices are implernented on all construction
Applications sites that use temporary or portable sanitary/septic waste systems.
Limitations • None identified.
Standards and Education
Specifications • Educate employees, subcontractors, and suppliers on sanitary/septic waste
storage and disposal procedures.
• Educate employees, subcontractors, and suppliers of potential dangers to
humans and the environment from sanitary/septic wastes.
• Instruct employees, subcontractors, and suppliers in identification of
sanitary/septic waste.
• Hold regular meetings to discuss and reinforce disposal procedures
(incorporate into regular safety meetings).
• Establish a continuing education program to indoctrinate new employees.
Storage and Disposal Procedures
• Temporary sanitary facilities shall be located away from drainage facilities,
watercourses, and from traffic circulation. When subjected to high winds or
risk .
