9. Approval of this FDCP does not in and of itself constitute or otherwise authorize any
site disturbance, preparation or construction. The developer is required to obtain all
necessary permits and clearances as set forth in any development approvals issued and
currently in effect pertaining to this site. This includes any type of testing, monitoring
or sampling required as a condition of development approval, such as that conducted
for archaeologic, hydrologic and geologic reporting purposes:
SITE DEVELOPMENT:
10. Pre -watering of all areas proposed for grading shall be in accordance with requirements
of the Public Works Department, based on the area soil conditions as described in the
associated soils report(s)..
11. Track -out and other accumulation of soil material(s) onto any paved areas outside the
limits of grading shall be minimized in accordance with the measures stipulated in the
FDCP. Any unpaved construction exit/entry point along existing paved roads/areas shall
be improved as set forth in the FDCP. Wet sweeping/flushing (dry -sweep not
permitted) of soil accumulations from all paved areas shall be conducted daily, and
kept damp during construction hours until so removed. Applicant shall provide details
on wheel washing method for acceptance prior to issuance of a grading permit.
12. All on -site traffic on unpaved roads shall be limited to 15 MPH as stated in the FDCP
application. Signs shall be posted at all entries and along all unpaved access and travel
ways at maximum 300-foot intervals.. Size and height of the signs shall be appropriate
for their respective locations, and shall not be posted on any adjacent private
properties. Project site superintendent(s) and any security personnel shall be
responsible, for enforcing this requirement.
13. All unpaved construction access and travel ways within the site shall be prepared for
traffic prior to commencing grading activities and kept watered down and compacted
to retain moisture content during all construction traffic/activity, including building
construction. At a minimum, temporary construction travel ways shall be improved to
a 20 foot width. All unpaved road lengths shall be watered each day, prior to and at
intervals during any traffic activity, and at the end of the day after all activity has
ceased. All track -out shall be removed as per Condition #10.
14. FDCP 99-73 indicates balanced grading. However, any on or off -site soil transport and
stationary storage piles shall be sufficiently stabilized, watered down and/or covered
as required. Minimum freeboard shall be as established by the Public Works
Department. Any borrow areas shall be routinely watered and chemically stabilized
after borrow activity to mitigate airborne dust. Off -site borrow/spreading areas shall
be subject to requirements of this FDCP, and any such areas outside the City limits
shall have the appropriate agency and property owner authorizations (see Cond. 3).
15. Any on -site temporary employee facilities (sales, construction, equipment
.storage/staging, etc.) shall be provided with paved, compacted or otherwise stabilized
parking and access during their operation, with those improvements to .be
constructed/installed to the applicable Public Works Department standards. This
requirement shall apply to any approval for such facilities under a minor use or other
permit process.
16. If approved on -site roadways/parking areas are constructed to ultimate design prior to
completion of construction activities, then traffic and parking shall be limited to those
paved areas as feasible. No vehicular parking or traffic of any kind is permitted on or
over any previously stabilized or undisturbed soil areas.
17. Disturbed but inactive development areas subject to additional grading or building
construction within 30 days of completion of the initial disturbance, shall be watered
daily in conjunction with watering of access roads and developing areas, unless an
appropriate dust suppressant defined in Chapter 6.16 of the LQMC and approved by
the California Water Quality Control Board, Region 7, or as specified in the FDCP, has
been applied in lieu of daily watering.
All disturbed areas where no further grading, construction or other land disturbance will
occur for at least 30 days, shall be stabilized with the dust suppressant specified in the
FDCP, or by establishment of vegetation, no later than four days after completion of
the initial grading. These areas shall be staked, posted or otherwise restricted in order
to prevent any access on or across them.
18. At least one water truck shall be stationed on -site on weekends and holidays. All
security personnel shall be alerted to the need for dust control and instructed to
monitor graded areas for wind -generated dust as part of their routine duties.
19. On Sundays, holidays and other non -construction days, personnel shall be on -call for
emergency watering in the event of high winds. Wind forecasts can be obtained by
dialing 1-800-CUT-SMOG and following menu options for Air Quality and High Wind
and Dust. In the event that winds are forecast to exceed 25 MPH (403.1 High Wind
Day), all construction activities and on -site traffic shall be closely monitored to insure
compliance with the FDCP. If such measures are ineffective in minimizing airborne
'dust, then grading activity shall cease until high wind conditions subside or other
effective dust control measures are employed to allow grading to continue.

RE: PM 10 PROGRAM REPORTING REQUIREMENTS FOR FUGITIVE DUST CONTROL
PLANS
Dear Developer/Builder:
The Coachella Valley PM IO.Program has been in its implementation phase since December, 1992.
Among. the required control measures was the enactment by Valley cities of dust control ordinances
which require builders to implement dust control actions during construction, demolition and paving
activities. In conjunction with City staff members, we ask your help with thre reporting requirements.
A significant aspect of the PM 10 Program is the need to report, statistical information to the Federal
Environmental Protection Agency via the South Coast AQMD and the State of California Air Resources
Board. In response to this requirement, a Dust Control Reporting Form has been created, a copy of
which is attached. It is requested that if any project developers have amounts to report for any PM 10
mitigation, these forms must be filled out. This form is intended to supplement Attachment "B" of the
Fugitive Dust Control Plan by providing specific cost figures related only to dust control measures.
The South Coast AQMD has requested that the retroactive operative date be January 1, 1993, for
reporting purposes. This means, that each jurisdiction is requested to review projects since that date
where PM 10 control measure expenses have been incurred by developers, whether or not they have
been incorporated as part of a Dust Control Plan, and forward this data to CVAG as soon as practical.
Your cooperation in completing these forms as part of the grading permit procedure will help assure
that the Coachella Valley and the development community as a whole receive deserved credit for the
effort to attain Clean Air Act standards for PM 10.
Very truly
