NOTES:
1. NO BEDDING MATERIAL TO BE USED. THEREFORE, DO NOT FOLLOW
STANDARD DRAWINGS FOR METHOD OF PIPE INSTALLATION FOR
OUTLET PIPE THROUGH EMBANKMENT.
2. 8" MIN. ORIFICE WITH SLUICE GATE IS FOR MAINTENANCE AND SHOULD REMAIN
CLOSED DURING NORMAL OPERATION. A GATE VALVE MAY BE
USED IN LIEU OF THE 8" SLUICE GATE.
3. SLUICE GATE SHALL PROVIDE WATERTIGHT SEAL. PROVIDE
ADEQUATE CLEARANCE FOR GATE OPERATION AND FOR PROPER
SEATING OF GATE OVER PIPE.
4. SELECT BOX STANDARD AS REQUIRED TO ACCOMMODATE SLUICE GATE
AND ORIFICE TRASH RACK WIDTH.
5. ENSURE TRASH RACK OPENS FREELY AND WITHOUT INTERFERENCE WITH
SLUICE GATE.
6. FOOTER DIMENSION (B) IS ADJUSTED FOR ANTI -FLOTATION.
7. WATER TIGHT SEALS ARE REQUIRED AT ALL PIPE CONNECTIONS TO STRUCTURE.
