shall be used, as required, to sprinkle the job site to keep down dust conditions and shall be used immediately after backfill.
DE -WATER OPERTATIONS: If de -watering operations are required and pumps are forcing water on City of La Quinta roads, it shall.be the
responsibility of the permittee (contractor) to control this water and to provide off-street barricades when necessary.
CLOSING STREETS: No street shall be closed. A minimum of one lane of traffic shall be maintained at all times to provide limited access for the
