(Rev. 1) Comment has not been addressed. Please provide proposed contours or spots of
elevations inside the parking garage.
11. Please check the Storm Drain Design Computations spreadsheet for consistency with the plans and
profiles. Measurements and hydrologic coefficients from the plan do not match the spreadsheet
(for example: STR -1 to STR -IA, & STR -1 to STR -EX3; ST -13).

proposed and existing pipes. Please check your CAD layers for any layers that might be turned
off (for example, STR -EX2, STR -EXI, etc.)
12. Please provide calculations for the pipe flow and capacity from manhole EX -2 to the pond.

STR -7, STR -8, STR -11, STR -12, and STR -14A due to the inlets being set on grade.
15. Storm sewer pipe slopes should be a maximum of 16 % or anchors per VDOT standards should be
provided.

example, STR -EX2).
23. Storm Drain Design Computations show pipe STR -14 to STR -13 to have excessive outlet
velocities greater than 15 fps.
24. Please provide a copy of the calculations, details and plan showing that the stormwater pond
design accounted for the water quality and quantity requirements of the Whitehouse site.
