SAND FENCING IS NOT PROPOSED TO BE USED FOR THIS PROJECT. ANDALUSIA HAS AN EXISTING 6 FOOT WALL AROUND THE ENTIRE PERIMETER OF THE PROJECT. THE CONSTRUCTION SITE IS LOCATED IN THE CENTRAL AREA OF THE PROJECT AND IS SURROUNDED BY THE EXISTING GOLF COURSE AND EXISTING RECREATIONAL FACILITIES THAT ARE OWNED AND MAINTAINED BY THE DEVELOPER. THE NEAREST RESIDENTIAL UNIT IS LOCATED APPROXIMATELY 175 FEET FROM THE EASTERLY BOUNDARY OF THE PROJECT WITH THE MAJORITY OF EXISTING RESIDENCES LOCATED IN EXCESS OF 300 FEET FROM THE CONSTRUCTION SITE. THE DEVELOPER PROPOSES TO USE ENHANCED SITE WATERING TO MITIGATE WIND BLOWN DUST ISSUES. J. PRE -WATERING SHALL COMMENCE AT LEAST THREE (3) DAYS PRIOR TO ACTUAL GRADING USING A TEMPORARY ON-SITE IRRIGATION SYSTEM CONNECTION TO ANY EXISTING WATER SYSTEM SHALL BE DONE IN COMPLIANCE WITH C.V.W.D. TEMPORARY WATER LINES SHALL BE INSTALLED WITH A MINIMAL DISTURBANCE OF ANY OFF-SITE AREAS THEY PASS THROUGH. WHEN THE GRADING BEGINS, A SPRINKLER SYSTEM SHALL BE PLACED AROUND THE PERIMETER OF THE PROJECT, WITH FREQUENT WATERING, ESPECIALLY IN THE TYPICALLY WINDY EVENINGS. PLACING THE PERIMETER SPRINKLERS ON THE SAND FENCE KEEPS THEM SAFE AND EFFECTIVE. WATERING FOR AREAS NOT COVERED BY THE SPRINKLERS SHALL BE PROVIDED BY WATER TRUCKS. (ONE TRUCK PER 8 ACRES FOR 8 HR. WORKDAYS. SEE ABOVE.) 4. ACTIVITY AREAS SUCH AS: EQUIPMENT STORAGE AREA, MATERIALS STORAGE AREA, TEMPORARY OFFICE TRAILERS, AND EMPLOYEE PARKING, SHOULD BE LOCATED IF POSSIBLE ON EXISTING PAVED SURFACES, IF TRAFFIC WOULD NOT BE AFFECTED. IN LIEU OF EXISTING PAVING, A SOIL STABILIZER THAT DOES NOT REQUIRE CONSTANT WATERING, SUCH AS A WASHED GRAVEL, OR "BIODEGRADABLE OIL" COULD BE USED FOR THE INITIAL STAGING AREA. ANY CHEMICALS USED MUST BE CLEARED WITH THE CITY AND REGIONAL WATER QUALITY CONTROL BOARD. 6. SPEED RESTRICTION SIGN LOCATION: 1 SPEED LIMIT SIGN AT CONSTRUCTION ACCESS 7.

OTHER PRELIMINARY WORK: PHASE "B':• ROUGH GRADING (MASS GRADING, PERIMETER WALLS) GENERAL REQUIREMENTS 1. HAULING PROCEDURES. ALL VEHICLES GOING FROM DIRT AREAS ONTO PAVED STREETS SHALL HAVE TIRES AND WHEELS INSPECTED AND WASHED IF NECESSARY TO AVOID "TRACKING -OUT" DIRT. TRUCKS HAULING DIRT ON PAVED STREETS SHALL MAINTAIN AT LEAST A HALF FOOT FREEBOARD" FROM RIM TO DIRT, AND COVER ALL DIRT OR DUSTY DEBRIS LOADS WITH AN APPROPRIATE TARP. THE HAUL ROUTE SHOULD BE SHOWN HEREON OR ON AN ATTACHED SHEET, AND SHALL BE CLEARED WITH THE CITY ENGINEER FOR ANY APPLICABLE TRANSPORT PERMITS PRIOR TO ITS USE. ALL HAULING TRUCKS SHALL HAVE A COPY OF THESE PROVISIONS WITH THEM AT ALL TIMES. THE IMPORT OR EXPORT SITE MUST HAVE A VALID GRADING PERMIT ALSO, AND SHOULD BE COMPLYING WITH ALL APPROPRIATE DUST MITIGATION MEASURES ALSO. WHEN PRACTICAL, TRUCKS AND EQUIPMENT SHOULD SHUT OFF ENGINES RATHER THAN IDLING FOR EXTENDED PERIODS, TO MINIMIZE EXHAUST EMISSIONS AND NOISE. THIS BECOMES MORE CRITICAL AS THE SIZE AND NUMBERS OF VEHICLES INCREASES. 2. ALL STRIPPED, GRADED OR OTHERWISE DISTURBED AREAS SHALL BE STABILIZED BY SOME APPROPRIATE MEANS. AREAS ACTIVELY BEING GRADED CAN USUALLY BE STABILIZED BY APPLYING LOTS OF WATER. DISTURBED AREAS NOT ACTIVELY BEING WORKED MAY BE EFFECTIVELY TREATED WITH SOME MORE DURABLE SOIL STABILIZER, SUCH AS HYDROMULCH, TO AVOID CONSTANT WATERING. THE PREFERRED METHOD OF SITE WATERING IS BY SPRINKLER, ESPECIALLY AROUND THE PERIMETER. SPRINKLERS MUST BE SET TO RUN ON WEEKENDS AND EVENINGS WHEN WATER TRUCK DRIVERS ARE NOT AVAILABLE, A TYPICAL WATER TRUCK CAN ONLY HANDLE WELL ABOUT 4 ACRES PER HOUR. J. IF PERIMETER BLOCK WALLS ARE TO BE BUILT THEY SHOULD BE GIVEN A HIGH PRIORITY SINCE THEY WILL HELP TO CATCH BLOWSAND AND COULD THEREBY REDUCE THE AMOUNT OF STREET SWEEPING REQUIRED. SITE SPECIFIC DETAILS: (PLEASE DESCRIBE ANY SPECIFIC OR ADDITIONAL CONTROL MEASURE PROPOSED.) 1. HAULING PROCEDURES. (AS SHOWN ABOVE UNLESS OTHERWISE DETAILED) PER GENERAL REQUIREMENTS. NO EXPORT FROM CONSTRUCTION SITE 2. SOIL STABILIZATION METHODS. ACTIVE AREA WATER SCHEDULE: (MIN. 4 TIMES PER 24 HRS.)

INACTIVE AREA STABILIZATION METHOD(S): (ACRYLIC POLYMER, HYDROMULCH, PLANTINGS, BIODEGRADABLE 'OIL'; OR AS SHOWN HERE) CHEMICAL STABILIZER SHALL INCLUDE GREEN COLORANT OR EQUAL AND USED ON INACTIVE AREAS. J. PERIMETER BLOCK WALL SCHEDULE: N/A 4. OTHER. AFTER 10 DAYS OF COMPLETING GRADING, AREAS THAT WILL NOT BE STABILIZED BY CONTINUED WATERING SHALL BE STABILIZED BY ACRYLIC POLYMER OR PLANTING PHASE "C" FINISH GRADING (UTILITY & STREET CONST.) GENERAL REQUIREMENTS. 1. DIRT STOCKPILED NEXT TO UTILITY TRENCHES SHALL BE KEPT WATERED OR OTHERWISE STABILIZED OR COVERED TO HELP COUNTERACT THEIR HIGH PROFILE EXPOSURE TO THE WIND. 2. ALL PREVIOUSLY ROUGH GRADED AREAS THAT WILL BE INACTIVE IN THIS PHASE SHOULD BE TREATED WITH A DURABLE SOIL STABILIZER OR GROUND COVER SYSTEM. IF A VEGETATED GROUND COVER IS UTILIZED IT IS ONLY NECESSARY TO GET IT INITIALLY ESTABLISHED, THE ROOT SYSTEM AND TOP STUBBLE MAY BE SUFFICIENT TO HOLD THE DUST EVEN IF WATERING IS DISCONTINUED. J. FOR TRACTS, MULTIPLE PARCELS, AND EXTENSIVE COMMERCIAL SITES, PAVED ACCESS TO THE BUILDING SITES SHALL BE COMPLETED AS SOON AS POSSIBLE. BUILDINGS. THIS CONSTRUCTION STAGE USUALLY INDICATES AN INCREASE IN THE NUMBERS OF WORKERS AND THEIR VEHICLES. ALSO, THE PAVED ACCESS IS RECOMMENDED FOR FIRE FIGHTING PURPOSES. IF PAVING IS DESIRED BEFORE ALL UTILITIES AND/OR LATERALS ARE INSTALLED, THE BASE LIFT OF ASPHALT IS SUFFICIENT FOR ACCESS. THE A.C. CAN BE 'CAPPED" LATER, LEAVING A FINAL SURFACE THAT IS FREE OF UTILITY CUTS AND PATCHES. 4. AS PAVED ACCESS IS EXTENDED, THE STAGING AREA CAN BE MOVED CLOSER TO THE BUILDING SITES. THE STORAGE AND OFFICE TRAILERS, EQUIPMENT, AND EMPLOYEE PARKING CAN BE MOVED ONTO PAVED PORTIONS OF THE SITE, SITE SPECIFIC DETAILS: (PLEASE DESCRIBE ANY SPECIFIC OR ADDITIONAL CONTROL MEASURE PROPOSED.) 1. TRENCH STOCKPILE TREATMENT• (WATER AS NECESSARY) BY WATER TRUCK 2. INACTIVE AREA TREATMENT: (SEAL WITH HYDROMULCH, ACRYLIC POLYMER, PLANTINGS, ETC.) ACRYLIC POLYMER OR PLANTING J.

UTIL., BLDG. CONST., LANDSCAPING) GENERAL REQUIREMENTS. 1. ALL INACTIVE AREAS SHOULD HAVE BEEN STABILIZED BY THIS STAGE, IF PREVIOUSLY COVERED, THE ACTUAL BUILDING PADS MAY NOW NEED TO BE STRIPPED, SCARIFIED, AND RECOMPACTED FOR BUILDING PAD COMPACTION AND ELEVATION CERTIFICATIONS. DUST WOULD BE KEPT DOWN BY WATERING, USUALLY BY TEMPORARY SPRINKLERS. 2. TRENCHING FOR BUILDING UTILITIES, DRYWELL CONSTRUCTION, POOLS, AND TENNIS COURT CONSTRUCTION FORM THE BULK OF EARTHWORK AFTER THE PADS HAVE BEEN CERTIFIED. TEMPORARY SPRINKLERS MAY STILL BE USED ON THE BUILDING SITE FOR DUST CONTROL PRIOR TO THE BEGINNING OF FRAMING. TREATMENT WITH A BIODEGRADABLE "OIL" APPROVED FOR DUST CONTROL IS RECOMMENDED WHERE IT IS DIFFICULT TO WATER, J. ESTABLISHING THE LANDSCAPE AND SPRINKLER SYSTEM AROUND THE PERIMETER OF LARGE PROJECTS SHOULD BE DONE AT THIS STAGE. PLANTINGS AROUND THE PERIMETER SERVE AS A WIND BUFFER AND COLLECTION SYSTEM FOR DUST AND SAND. IT IS GOOD TO HAVE DUST AND SAND WELL UNDER CONTROL PRIOR TO THE BUILDING PHASE FOR THE SAKE OF CERTAIN GLUING AND PAINTING PROCESSES THAT CAN BE RUINED BY BLOWSAND OR DUST. 4. DISTURBED AREAS AROUND BUILDINGS SHOULD BE WATERED BY HAND FOR DUST CONTROL UNTIL SUCH TIME THAT THE SPRINKLER SYSTEM IS FULLY FUNCTIONAL AND GROUND COVER AND OR LANDSCAPING IS ESTABLISHED. IF WATERING IS DIFFICULT DUE TO BUILDING INTERFERENCE, CHEMICAL OR MULCH TREATMENTS ARE AVAILABLE THAT CAN STABILIZE THE SOIL WITHOUT FREQUENT WATERING. 5. CONSTRUCTION DUST SUCH AS FROM CEMENT, PLASTER, PAINT OVERSPRAY, WOOD CUTTING, GRINDING OPERATIONS, ETC., SHOULD BE MINIMIZED ALSO. A PERIMETER BARRIER OF SPRINKLERS AND PLANTINGS CAN SERVE TO CATCH SOME OF THIS POTENTIALLY HAZARDOUS MATERIAL AS WELL AS NATURAL DUST AND BLOWSAND. CONCENTRATIONS OF CONSTRUCTION DUSTS CAN RESULT FROM WASHING OF EQUIPMENT AND SHOULD BE PROPERLY DISPOSED OF BEFORE THEY CAN DRY OUT AND BLOW OR BE WASHED ACROSS PROJECT BOUNDARIES. 6. NOTE THAT SWALES SHOULD BE INSPECTED BY CITY PRIOR TO SETTING OF PERMANENT GROUND COVER OR OTHER PLANTS, SITE SPECIFIC DETAILS.

ANY WATER TRUCKS OR VEHICLES SERVICING SPRINKLERS WOULD CONTINUE. 2. IN THE EVENT THAT AN ON-SITE IRRIGATION SYSTEM IS NOT INSTALLED AND/OR OPERATIONAL, THE CITY WILL CAUSE THE SITE TO BE WATERED OR TREATED WITH DUST CONTROL CHEMICALS. THE DUST CONTROL SECURITY WILL BE UTILIZED FIRST TO COVER ANY COSTS INCURRED. IF COSTS EXCEED ANY DUST CONTROL SECURITY REMAINING, ADDITIONAL COSTS MAY BE ASSESSED AGAINST THE OWNER OF THE PROJECT. J. IN THE EVENT AN ON-SITE IRRIGATION SYSTEM IS INSTALLED, BUT ITS CONTROL CLOCK HAS NOT TURNED THE SYSTEM ON WHEN NEEDED, THE CITY MAY TAKE ALL NECESSARY STEPS TO TURN ON THE SYSTEM. IF IT IS INACCESSIBLE BEHIND LOCKED GATES OR LOCKED CONTROL BOXES, AND THE CITY CAN NOT FIND THE APPROPRIATE KEYS, THE CITY MAY CUT OR BREAK LOCKS AS NECESSARY. E. IF, IN THE OPINION OF THE CITY ENGINEER OR HIS DESIGNEE, THE INTENSITY, FREQUENCY OR DURATION OF FUGITIVE DUST EMISSIONS FROM THE SITE CONSTITUTES A HAZARD TO THE SAFETY OF THE PUBLIC, BY INTRUSION BEYOND THE PROJECT BOUNDARY, THE CITY ENGINEER OR HIS DESIGNEE OR AGENT MAY IMMEDIATELY ENTER UPON THE SITE OR IMMEDIATELY TAKE OTHER SUCH ACTION AS MAY BE NECESSARY TO REMEDY THE HAZARD, SUCH AS, BUT NOT LIMITED TO COMMENCING WATERING ON THE SITE OR ORDERING THE CESSATION OF ANY EMISSION -GENERATING ACTIVITY OCCURRING ON-SITE.
