DRAINAGE CONTROL. 6.06 The Developer shall, at its sole cost and expense, control surface drainage within the Development Area to the satisfaction of the Manager, Urban Development through:
DRAINAGE CONTROL. Contractor shall provide for the drainage of storm water and such water as may be applied or discharged on the Site in performance of the Work. Drainage facilities shall be adequate to prevent damage to the Work, Site and adjacent property. Also drainage facilities shall be constructed to minimize the potential pollution to the ocean. Existing drainage channels and conduits shall be cleaned, enlarged or supplemented as necessary to carry all increased runoff attributable to Contractor's operations. Dikes shall be constructed as necessary to divert increased runoff from entering adjacent property (except in natural channels), to protect District's private property and utility owner's facilities and the Work, and to direct water to drainage channels or conduits. Retention of drainage on the Site shall be provided as necessary to prevent downstream flooding.
DRAINAGE CONTROL. Contractor shall control drainage at each Transfer Station, to the greatest extent possible, in order to minimize the creation of, and prevent uncontrolled off- site migration of, contact water. Republic shall be responsible for maintaining updated SWPPP’s for each of the Transfer Stations and the Materials Recovery Facility and shall be responsible for securing storm water samples as may be required by the Regional Water Quality Control Board or other regulatory agencies. Contractor shall be responsible for implementation of BMP’s that are operational in nature such as the placement of canvass covers, straw wattles, drains inserts, sweeping and the like. Republic shall be responsible for implementation of BMP’s that are structural in nature such as permanent canopies, storm water treatment systems, metal covers to permanent containers or bunkers, and the like. The parties shall work together to control storm water run off in a manner that is consistent with applicable law and the permits for the Transfer Stations and the Material Recovery Facility.
DRAINAGE CONTROL. The County shall be responsible for the maintenance and repair of all drainage structures and for the construction of new facilities as may be required for the control of surface water run-on and run-off in order to prevent damage to site facilities and the accumulation of standing water in operations areas.
DRAINAGE CONTROL. The Contractor shall maintain drainage within and through the work areas. Earth dams will not be permitted in paved areas. Temporary dams of native material, sandbags, or other acceptable material will be permitted when necessary. Such dams shall be removed from the site as soon as their use is no longer necessary.
DRAINAGE CONTROL. The Contractor shall maintain drainage within and through the work areas. Earth dams will not be permitted in paved areas. Temporary dams of sandbags, asphaltic concrete, or other acceptable material will be permitted when necessary. Such dams shall be removed from the site as soon as their use is no longer necessary. The Contractor shall ensure that storm and drainage water does not pond due to the temporary blockage of existing drainage facilities. To this end, the Contractor shall provide temporary works that allow for the passage of storm and drainage water in a manner equivalent to the existing drainage system. No separate payment will be made for any work performed or material used in drainage control. Full compensation for such controls shall be considered as included in the price paid for the various items of work involved and no additional compensation will be allowed therefor. ADD:
DRAINAGE CONTROL. AREA A/B The FM 1512 relocation right-of-way is approximately the divider for the drainage in Area A. Drainage to the south and east of the right-of-way flow into Pond 023. Drainage to the north and west of the right-of-way and pit water flow into Mine Creek and Pond 009. Mine Creek permanent channel is being built as the pit advances. A gap is being left in the spoils and shaped during regrade. The diversion will channel run-off into Pond 009. Water will be controlled by pit dewatering and pumped into Mine Creek diversion. A spoil ridge will protect the pit and the spoil configuration will drain water away from the pit and regrade. Drainage in the reclaimed areas is controlled by ponds. Reclamation Ponds RP-A2 and A9 flow into Pond 023. Reclamation Ponds RP-A1, A3, A4, A5, A6 and A7 flow into Pond 009. Sediment Pond 027 was constructed in 1998 to allow for emergency reserves in Area B to be mined. Sediment Pond 028 will he complete in the fall of 1998 and will contain the overland drainage as mining progresses in Area B. Area C In Area C south, Lambs Creek Phase III channels pit water south into Pond 016 and Pond 018. Phase III diverts Lambs Creek through the spoil ridges parallel to the pit. The runoff from the regrade is channeled into this diversion and discharged into Pond 016 and Pond 018. During the next several years, inactive pits in the south half of the Area C pit will be left open as needed for more than a year. A spoil ridge will be left to control run-off into these pits. Area D As mining progresses to the east and begins to impact Pond 026 and Sediment Pond P01-D will be constructed to reduce the drainage area of Pond 026. Sediment Pond P02-D will be located at the end pit of the east-west pits and will be utilized in conjunction with P01-D to significantly reduce the volume of drainage on Pond 026 and on Pond 024 as mining progresses to the south. A spoilside diversion will be built to the north of the east-west pits. This diversion will channel surface runoff to the south during the mining of the east-west pits.
DRAINAGE CONTROL. The Contractor shall ensure that storm and drainage water does not pond due to the temporary blockage of existing drainage facilities. To this end, the Contractor shall provide temporary works which allow for the passage of storm and drainage water in a manner equivalent to the existing drainage system. The capacity of unlined and concrete-lined channels shall be maintained as follows: April 15 to May 31 33% June 1 to August 31 5% September 1 to October 15 33% October 16 to April 14 100% Any work which could adversely affect the hydraulic capacity or structural integrity of a flood control channel shall be performed during the period between April 15 and October 15. Any work started after April 15 shall be completed prior to the following October 15 and shall be coordinated with the Agency’s Storm Water Engineering Division, Operations Section, (000) 000-0000.
