PM102019-0004PLEASE READ AND FILL OUT THIS DOCUMENT APPROPRIATELY, EVEN SMALL PROJECTS MUST
DO THEIR PART. P% p DUST (POWDERY OUST OF 10 MICRONS OR SMALLER DIAMETER) HAS
BEEN IDENTIFIED AS A POTENTIALLY SERIOUS HEALTH THREAT. THIS FINE DUST CAN LODGE
DEEP IN THE LUNGS AND HAS BEEN ASSOCIATED WITH BRONCHITIS AND OTHER RESPIRATORY
ILLNESSES. DESERT DUST CAN BE PARTICULARLY UNHEALTHFUL, BEING ASSOCIATED WITH
"DESERT LUNG SYNDROME" AND LUNG INFEC77ONS CAUSED BY FUNGAL SPORES CARRIED IN
DESERT DUST. CHILDREN, THE ELDERLY, AND PERSONS W/TH RESPIRATORY CONDITIONS, ARE
PARTICULARLY SENSITIVE TO FINE DUST, BUT EVERYONE IS ADVERSELY AFFECTED BY THE
RELA77VELY HIGH LEVELS OF PA4 THAT OCCUR IN THE COACHELLA VALLEY. LARGER SAND
PAR77CLES CAN BE TURNED INW THIS DUST THROUGH THE GRINDING ACTION OF 77RES ON
ROADWAYS AND THROUGH REPETITIVE PLOWING AND DISKING OPERATIONS.

1. WRITTEN AND NOTARIZED PERMISSION LETTERS SHALL BE SUBMITTED TO THE PUBLIC WORKS
DEPARTMENT FROM ANY ADJACENT LAND OWNERS WHOSE PROPERTY WILL BE USED IN ANY
MANNER FOR CONSTRUCTION, STAGING, ACCESS, ETC., PRIOR TO ANY SUCH USAGE.
THE OWNER AND AUTHORIZED DUST CONTROLLER FOR THIS PROJECT WILL BE RESPONSIBLE
FOR THE DUST CONTROL ON ANY OFF -SITE DISTURBED AREAS AS WELL AS ON THIS PROJECT
A DUST CONTROL SECURITY OF $2, 000 PER ACRE, OR AS OTHERWISE APPROVED BY THE CITY
ENGINEER, SHALL BE POSTED FOR ALL AREAS TO BE DISTURBED BY THE PROJECT, BOTH
ON -SITE AND OFF -SITE DISTURBANCE OF SITE AREAS NOT INCLUDED IN THIS AGREEMENT
SHALL BE REASON FOR THE CITY TO ASSESS ADDITIONAL CHARGES, AND POSSIBLY STOP ALL
WORK AT THE SITE UN77L THE EXTENT OF THE DISTURBANCE IS MEASURED. THEREFORE, IF IT
IS SUSPECTED THAT OFF -SITE AREAS MAY BE DISTURBED DURING 174E WORK, SHOW THEM ON
THIS PLAN AND MAKE THE APPROPRIATE ARRANGEMENTS IN ADVANCE.
2. SAll FENr'.•'VG OF EITHER THE WOOD AND WIRE OR THE PLAS77C TYPE, SHALL BE INSTALLED
AROUND THE PERIMETER OF THE PROJECT ON ALL SIDES THAT DO NOT HAVE EXISTING MASONRY
WALLS OR SIMILAR SOLID FENCING OR HEDGES. THIS SERVES THE MULTIPLE PURPOSES OF -
CATCHING SOME WINDBLOWN DUST; REDUCING WIND SPEEDS ON THE PROJECT PERIMETER, AND
RESTRICTING VEHICULAR ACCESS POINTS INTO THE. PROJECT. THIS RESTRICTED ACCESS HELPS
REDUCE DAMAGE TO ANY "CRUST' OF STABILIZED SOIL ON THE PROJECT, AND ALLOWS PLACING
OF THE EXIT WHERE 'TRACK OUT" CAN BE STOPPED PER 15 BELOW.

3. 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 T14E TYPICALLY WINDY EVENINGS
PLACING THE PERIMETER SPRINKLERS ON 774E 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.
5. THE 77RES OF VEHICLES BEING USED ON -SITE SHOULD BE INSPECTED AND WASHED IF
NECESSARY TO STOP TRACKING OF DIRT ONTO PUBLIC STREETS IF EXTENSIVE EXPORT OR
IMPORT OF DIRT IS TO BE DONE, A PAVED OR GRAVELED WHEEL WASHING AREA AT LEAST 12'
WIDE BY 100' LONG SHOULD BE PROVIDED AT THE EXIT, TO FACILITATE THE INSPECTION AND
CLEANING OF TIRES "RUMBLE STRIPS" MADE FROM LUMBER, RAILROAD 7RACKOR SIMILAR
MATERIALS CAN HELP REDUCE THE MUD GETTING ONTO THE CLEANING AREA. STREET SWEEPING
AND WASHING IS S77LL TYPICALLY REQUIRED, BUT MAY BE REDUCED BY PROPER USE OF A
"WHEEL WASHING AREA" LIKE THIS THEY ARE REQUIRED ON PROJECTS OVER 5 ACRES OR WITH
OVER 5,000 CUBIC YARDS OF IMPORT OR EXPORT.
6. A STANDARD SIGN WITH THE FOLLOWING INFORMATION MUST BE POSTED ON THE SITE, AT LEAST
ONE SIGN PER FRONTING STREET. T74E SIGN MUST INCLUDE: THE GRADING PERMIT NUMBER,
THE PROJECT NAME, MAP NUMBER IF APPROPRIATE, THE AUTHORIZED DUST CONTROLLER PHONE

GENERAL REQUIREMENTS
1. HAULING PROCEDURES.
ALL VEHICLES GOING FROM DIRT AREAS ONTO PAVED STREETS SHALL HAVE 77RES 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 W17H 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. 774/S
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 L07S 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.
4. VEHICLES TRAVELING ON DIRT AND/OR ON UNPAVED ROADS SHOULD RESTRICT THEIR SPEED TO
15 M.P.H. MAXIMUM. SIGNS TO THAT EFFECT SHOULD BE PLACED AT 774E PROJECT ENTRANCE
ON PROJECTS OVER 5 ACRES TO IMPROVE COMPLIANCE.
5. UNPAVED ROADS SHALL BE WATERED A MINIMUM OF 4 PASSES OR AS NEEDED.

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.
3. FOR TRACTS, MULTIPLE PARCELS, AND EXTENSIVE COMMERCIAL SITES, PAVED
ACCESS TO THE BUILDING SITES WILL BE REQUIRED PRIOR TO FRAMING OF THE
BUILDINGS THIS CONSTRUCTION STAGE USUALLY INDICATES AN INCREASE IN THE
NUMBERS OF WORKERS AND THEIR VEHICLES ALSO, THE PAVED ACCESS IS
RECOMMENDED FOR FIRE F7GH77NG PURPOSES. IF PAVING IS DESIRED BEFORE
ALL U77LIT7ES 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 PORT70NS OF THE SITE

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, SCARIF7ED,
AND RECOMPACTED FOR BUILDING PAD COMPACTION AND ELEVA77ON CERTIFICATIONS
DUST WOULD BE KEPT DOWN BY WATERING, USUALLY BY TEMPORARY SPRINKLERS
2. TRENCHING FOR BUILDING UTILITIES, DRYWELL CONSTRUCTION, POOLS, AND TENNIS
COURT CONSTRUCT70N FORM THE BULK OF EARTHWORK AFTER THE PADS HAVE BEEN
CERTIFIED. TEMPORARY SPRINKLERS MAY S77LL BE USED ON THE BUILDING SITE FOR
DUST CONTROL PRIOR TO THE BEGINNING OF FRAMING TREATMENT W1774 A BIODEGRADABL
"OIL" APPROVED FOR DUST CONTROL IS RECOMMENDED WHERE IT IS DIFFICULT TO WATER.
3. 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 COLLEC77ON 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 77ME THAT THE SPRINKLER SYSTEM IS FULLY FUNC77ONAL
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 PLAN7NGS CAN SERVE TO CATCH SOME OF THIS
POTENTIALLY HAZARDOUS MATERIAL. AS WELL AS NATURAL DUST AND BLOWSAND.
CONCENTRATIONS OF CONSTRUCTION DUSTS GAN 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 CITr PRIOR TO SETTING OF PERMANENT
GROUND COVER OR OTHER PLANTS,
