degrees.
20. Please submit inlet drainage area maps with drainage acreage, limits of all areas and sub -areas
draining to proposed structures (and existing structures or channels which will be impacted,
hydrologic coefficients, and time of concentration for each drainage area.

B. Stormwater Management Plan (WPO200900030)
22. Please label pre - development and post - development drainage area maps with acreage, coefficients,
and time of concentration.
(Rev. 1) Comment has been addressed.

illustrate how this area will be treated.
(Rev. 1) Comment has not been addressed. Stormceptor facilities are awarded up to 20%
removal rate in the Virginia Stormwater Management Handbook (Section 3.15). However, the

Method Spreadsheet) is 83%.
25. Please provide Albemarle County general stormwater notes. Please refer to the Design Standards
Manual.

Engineering Review Comments

29. Prior to the installation of the curb and gutter and inlets, much of the site does not drain to the
proposed sediment basin. It seems that a diversion dike may be necessary at the top of the
proposed lot embankment.
(Rev. 1) Comment has been addressed.
30. Please provide dust control symbols (DC).
(Rev. 1) Comment has been addressed.
31. There seem to be discrepancies between the sediment basin calculations on the plans and the
sediment basin sizing computations.
(Rev. 1) Comment has not been addressed. The pond bottom elevation of the plan detail does
not match with the engineering calc. packet.
32. The construction entrance must drain to a sediment trap.
(Rev. 1) Comment has not been addressed. The construction entrance should be moved up the
travelway so that a sediment trap can be installed outside of the VDOT right -of -way.
33. Please provide a staging and /or parking area.
(Rev. 1) Comment has been addressed.
34. Please provide outlet protection to all proposed outlets.
(Rev. 1) Comment has been addressed.
