WHILE THE PRELIMINARY GEOTECHNICAL INVESTIGATION AND REPORT PROVIDE GUIDELINES WHICH ARE USED BY THE DESIGN TEAM, I.E., ARCHITECTS, GRADING ENGINEERS, STRUCTURAL ENGINEERS, LANDSCAPE ENGINEERS, ETC., IN COMPLETING THEIR RESPECTIVE TASKS, REVIEW OF PLANS AND SITE REVIEW AND TESTING DURING EARTHWORK OPERATIONS ARE VITAL ADJUNCTS TO THE COMPLETION OF THE GEOTECHNICAL ENGINEER'S TASKS. THE MOST PREVALENT CAUSE OF FAILURE OF A STRUCTURE FOUNDATION SYSTEM IS LACK OF ADEQUATE REVIEW AND TESTING DURING THE EARTHWORK PHASE OF THE PROJECT PROJECTS RARELY REACH COMPLETION WITHOUT SOME ALTERATION BEING REQUIRED SUCH AS MAY RESULT FROM A CHANGE IN SUBSURFACE CONDITIONS, AN AMENDMENT IN THE SIZE AND SCOPE OF THE PROJECT, A REVISION OF THE GRADING PLANS OR A VARIATION IN STRUCTURAL DETAILS. OCCASIONALLY, EVEN MINOR CHANGES CAN SIGNIFICANTLY AFFECT THE PERFORMANCE OF FOUNDATIONS. THE MOST PREVALENT SECONDARY CAUSE FOR FOUNDATION FAILURE IS INADEQUATE IMPLEMENTATION OF GEOTECHNICAL RECOMMENDATIONS DURING THE FORMULATION OF FOUNDATION DESIGNS AND GRADING PLANS. THE ERROR IN A FOUNDATION DESIGN OR AN OMISSION OF A KEY ELEMENT FROM A GRADING PLAN OCCURS MOST OFTEN AS A RESULT OF INADEQUATE COMMUNICATION BETWEEN THE VARIOUS PROJECT CONSULTANTS AND -- WHEN A CHANGE IN CONSULTANTS OCCURS -- IMPROPER TRANSFER OF AUTHORITY AND RESPONSIBILITY. (2IFTHE CIVIL ENGINEER, THE SOILS ENGINEER, THE ENGINEERING GEOLOGIST OR THE TESTING AGENCY OF RECORD IS CHANGED DURING THE COURSE OF THE WORK, THE WORK SHALL BE STOPPED UNTIL THE REPLACEMENT HAS AGREED TO ACCEPT THE RESPONSIBILITY WITHIN THE AREA OF HIS TECHNICAL COMPETENCE FOR APPROVAL UPON COMPLETION OF THE WORK.) IT IS IMPERATIVE, THEREFORE, THAT ANY REVISIONS TO THE PROJECT SCOPE, ANY CHANGE IN STRUCTURAL DETAIL, OR CHANGE IN CONSULTANT, BE BROUGHT TO THE ATTENTION OF SOILS ENGINEERING, INC. TO ALLOW FOR TIMELY REVIEW AND REVISION OF RECOMMENDATIONS AND FOR AN ORDERLY TRANSFER OF RESPONSIBILITY AND APPROVAL. IT IS THE RESPONSIBILITY OF THE OWNER OR HIS REPRESENTATIVE TO ENSURE THAT A REPRESENTATIVE OF OUR FIRM IS PRESENT AT ALL TIMES DURING EARTHWORK OPERATIONS RELATING TO SITE PREPARATION AND GRADING, SO THAT RELATIVE COMPACTION TESTS CAN BE PERFORMED, EARTHWORK OPERATIONS CAN BE OBSERVED AND COMPLIANCE WITH THE RECOMMENDATIONS PROVIDED HEREIN CAN BE ESTABLISHED.

ALTERNATE METHODS PROVIDING EQUAL OR GREATER PROTECTION MAY BE UTILIZED. FOR ADDITIONAL BMPs REFER TO CALIFORNIA STORMWATER BMP HANDBOOKS. 2. ALL CONSTRUCTION SHALL CONFORM TO THIS PLAN AND IMPLEMENTED IN ACCORDANCE WITH THE REQUIREMENTS OF THE CURRENT NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) PERMIT, THE STATE'S GENERAL PERMIT, AND LOCAL STORMWATER MANAGEMENT PROGRAMS. CONTRACTOR SHALL OBTAIN A COPY OF THESE PROGRAMS FOR HIS OWN USE. 3. THE CONTRACTOR MUST IMPLEMENT AN EFFECTIVE COMBINATION OF EROSION AND SEDIMENT CONTROL ON ALL DISTURBED AREAS PER THE BMP HANDBOOK. 4. NON—STORMWATER DISCHARGES SHALL BE PROHIBITED FROM ENTERING ANY STORM DRAIN SYSTEM AND THE EXISTING STREET. 5. NON—STORMWATER MANAGEMENT CONTROLS AND WASTE MANAGEMENT CONTROLS SHALL BE PROPERLY IMPLEMENTED AS NECESSARY TO COMPLY WITH ALL APPLICABLE CODES. 6. SEDIMENT CONTROL PRACTICES SHALL EFFECTIVELY PREVENT A NET INCREASE OF SEDIMENT LOAD IN STORMWATER DISCHARGE. 7. ALL CONTROL DEVICES SHALL BE INSPECTED FOR PROPER INSTALLATION PRIOR TO QUALIFYING RAIN EVENTS AS OUTLINED IN THE GENERAL ORDER. 8. A STANDBY CREW FOR EMERGENCY WORK SHALL BE AVAILABLE AT ALL TIMES. NECESSARY MATERIALS SHALL BE AVAILABLE ONSITE AND STOCKPILED AT CONVENIENT LOCATIONS TO FACILITATE RAPID CONSTRUCTION OF TEMPORARY DEVICES OR DAMAGED EROSION CONTROL MEASURES OR SEDIMENT CONTROL MEASURES WHEN RAIN IS IMMINENT. 9. AFTER A RAINSTORM, ALL SILT AND DEBRIS SHALL BE REMOVED FROM CHECK BERMS, DESILTING BASINS AND OTHER DEVICES. ANY DEVICES AND SLOPE SURFACE PROTECTION DAMAGED DURING A RAINSTORM SHALL BE IMMEDIATELY REPAIRED. 10. POLLUTANTS SHALL BE REMOVED FROM STORMWATER DISCHARGES TO THE MAXIMUM EXTENT PRACTICABLE (MEP) THROUGH DESIGN AND IMPLEMENTATION OF THIS PLAN. 11. PORTABLE SANITARY FACILITIES SHALL BE LOCATED ON RELATIVELY LEVEL GROUND AWAY FROM TRAFFIC AREAS, DRAINAGE COURSES AND STORM DRAIN INLETS. 12. EMPLOYEES, SUBCONTRACTORS AND SUPPLIERS SHALL BE EDUCATED BY THE DEVELOPER OR HIS GENERAL CONTRACTOR ON ALL BEST MANAGEMENT PRACTICES (BMPs) INCLUDING CONCRETE WASTE STORAGE AND DISPOSAL PROCEDURES. 13. THE CONTRACTOR SHALL PREVENT A DUST NUISANCE FROM ORIGINATING FROM THE SITE OF WORK AS A RESULT OF HIS OPERATIONS DURING THE EFFECTIVE PERIOD OF THIS PROJECT.

THE CONTRACTOR SHALL OBTAIN A COPY OF THE REGULATION FOR HIS USE. UST CONTROL BEST MANAGEMENT PRACTICES: 1. THE CONTRACTOR SHALL PREVENT A DUST NUISANCE FROM ORIGINATING FROM THE SITE OF WORK AS A RESULT OF HIS OPERATIONS DURING THE EFFECTIVE PERIOD OF THIS PROJECT. PREVENTATIVE MEASURES SHALL BE TAKEN BY THE CONTRACTOR TO MITIGATE THE IMPACT OF DUST AND PM10 EMISSIONS ACCORDING TO THE SAN JOAQUIN VALLEY AIR POLLUTION CONTROL DISTRICT REGULATION VIII (8). THE CONTRACTOR SHALL OBTAIN A COPY OF THE REGULATION FOR HIS USE. THESE MEASURES SHALL INCLUDE, BUT NOT BE LIMITED TO THE FOLLOWING: A. PRE —ACTIVITY: a) PRE —WATER SITE SUFFICIENT TO LIMIT VISIBLE DUST EMISSIONS (VDE) TO 20% OPACITY. b) PHASE WORK TO REDUCE THE AMOUNT OF DISTURBED SURFACE AREA AT ANY ONE TIME. B. DURING ACTIVE OPERATIONS: a) APPLY WATER OR OTHER APPROVED SUBSTANCE SUFFICIENT TO LIMIT VDE TO 20% OPACITY. b) LIMIT ACTIVITY TO PERIODS OF LOW OR NO WIND, OR CONSTRUCT AND MAINTAIN WIND BARRIERS SUFFICIENT TO LIMIT VDE TO 20% OPACITY. c) APPLY WATER OR OTHER APPROVED SUBSTANCE TO UNPAVED HAUL/ACCESS ROADS AND UNPAVED VEHICLE/EQUIPMENT TRAFFIC AREAS SUFFICIENT TO LIMIT VDE TO 20% OPACITY AND MEET THE CONDITIONS OF A STABILIZED UNPAVED ROAD SURFACE. C. TEMPORARY STABILIZATION DURING PERIODS OF INACTIVITY: a) RESTRICT VEHICULAR ACCESS TO THE AREA. b) APPLY WATER OR OTHER APPROVED SUBSTANCE SUFFICIENT TO COMPLY WITH THE CONDITIONS OF A STABILIZED SURFACE. IF ANY AREA HAVING 0.5 ACRES OR MORE OF DISTURBED SURFACE AREA REMAINS UNUSED FOR SEVEN OR MORE DAYS, THE AREA MUST COMPLY WITH THE CONDITIONS FOR A STABILIZED SURFACE AREA AS DEFINED IN RULE 8011, D. CARRYOUT AND TRACKOUT ON PUBLIC ROADS: a) ALL VISIBLE CARRYOUT AND TRACKOUT WITHIN 50 FEET OF THE SITE SHALL BE REMOVED AT THE END OF EACH WORKDAY. TRACKOUT BEYOND 50 FEET Or THE SITE SHALL BE REMOVED IMMEDIATELY. b) CLEANUP SHALL BE ACCOMPLISHED BY MANUAL SWEEPING OR APPROVED EQUIPMENT AND METHOD AS SPECIFIED BY THE SJVAPCD. c) THE USE OF BLOWER DEVICES OR DRY ROTARY BRUSHES OR BROOMS, FOR REMOVAL OF CARRYOUT AND TRACKOUT ON PUBLIC ROADS IS EXPRESSLY PROHIBITED. d) ANY PERMITS REQUIRED FOR MUD AND DIRT CLEANUP SHALL BE OBTAINED BY THE CONTRACTOR.
