RE: Response Letter #2 for SUB2021-00124 Proffit Road Townhomes South — Road Plan
Dear David,
Thank you for your review of the road plan for Proffit Road Townhomes South. This letter contains
responses to County comments dated October 20, 2021.Our responses are as follows:
12. Provide turning movement for fire/rescue and delivery trucks. 100' sight distance shall be
maintained. (Rev.1) Acknowledged. I'm waiting to hear back from fire/rescue on the turning
movements; otherwise comment addressed.
There were no comments from fire/rescue.
13. Note: Submit plat for the dedication of ROW and recording of easements. (Rev.1) Comment still
applies.
Acknowledged.
14. (Rev.1) Sheet 5, etc.:
a. Provide CG-2 at turnarounds.
CG-2 labels have been added to the turnarounds. Please see Sheet C5.
b. Provide CG-9 driveway entrances instead of roll top curb shown. The roll-top curb doesn't
provide a smooth transition into driveways. VDOT doesn't allow roll-top to be used in
driveways.
Per VDOT Appendix B — Subdivision Street Design Guide, Section B -4 Elements of
Typical Section, G. Curb and gutter designs, #3 — C. "Rolltop curb and gutter may be
used along subdivision streets having a design speed not greater than 30 mph."
The proposed roads will have 25 mph as a design speed; therefore, the rooltop curb will
be in compliance with the VDOT Subdivision Street Design Standards.
c. Provide curb transitions for the locations shown in purple highlight below.
Curb transitions labels are provided on Sheet C5 on the locations highlighted in purple.
A curb transition detail was added to the plan. Please see detail 4 on Sheet C14.
d. Remove ribbon curb provide CG-2.
There was no ribbon between lot 4 and lot 5. CG-2 is provided. A label was added to
Sheet C5 to clarify.
e. Remove CG-12 in parking spot.
The label has been revised to CG-6.

The angle of intersection is now labeled on Sheet C5.

Street signs locations have been revised so that they're 2' away from FOC.

18. (Rev.1) Show roof drainage and where they connect. Install header pipe to collect water from
downspouts (3 or more lots).
Roof drain for Lot 32 - Lot 40 is now shown on Sheet C7 to meet the Albemarle County Design
Standards. The discharge was accounted for in the approved stormwater calculations.
Roof Drain is not necessary for lots 1-21 as there is no cross lot runoff condition.
Please note that all the VDOT details have been removed from the plan with this revision per the
new VDOT requirements. A note was added to Sheet C1 under "VDOT Details" to instruct the
contractor to review the VDOT details specified in this project,
