Notes on Fueling Island
1. Install drains centered between rows of fueling pumps. Drains shall connect to dead-end
sump(s).
2. Fueling pad to be impervious Portland cement or equivalent, sloping 2-4% on all sides
toward the drains.
Pad shall extend at least 6 ft. from edge of fueling dispenser.
3. If a graded pad is not achievable, the City may approve a pad with berms
located on all downslope edges of pad and a drain located near a bermed edge.
4. Fuel island shall be covered by a canopy to prevent rain or snow from falling
on the pad. Cover shall extend at least 2 ft. beyond the edge of the grade break
on the perimeter of the pad (or extend past berms).
5. Rain runoff from canopy can be directed to storm drain but not to pad.
Notes on Dead-End Sump
1. Sump shall be a solid wall inlet vault (no outlet openings). The City recommends a
6'L x 4'W size vault with a depth of 5½' which gives a capacity of approx. 700 gals.
Smaller sizes may be submitted for approval.
2. Top should fit a steel inlet grate rated H-20 with minimum 6” top frame thickness.
