Review #1
Dear Mr. Wentland & Ms. Kanellopoulos:
The Department of Transportation, Charlottesville Residency Transportation and Land Use
Section, has reviewed the above referenced plan as submitted by Timmons Group, dated 30
October 2019, and offers the following comments:
1. Please show mill and overlay on plans in accordance with WP-2. Show limits of mill and
overlay to adjacent travel lane. Also, please add the WP-2 detail to the plans.
2. Please provide an MOT plan in accordance with the Virginia Work Area Protection
Manual. MOT plan should be on a separate sheet and designed for this project, include
the proposed mill and overlay.
3. Provide distances to nearest entrances or intersections on SR 631.
4. Please label SR 63I on the plan sheets.
5. Landscaping plants and trees adjacent to the sight distance triangle will need to be
maintained in area between 2 and 7 feet above ground as a clear zone to preserve sight
lines and accommodate pedestrians.
6. There are multiple pipe flow velocities that exceed 10 fps. The drainage manual states
that pipe velocities in excess of 10 fps are to be avoided. We recommend that velocities
be adjusted accordingly.
7. Several drainage structures on plan view do not appear to have designation labels
matching spreadsheets and profiles.
8. Please show how CD-1's will drain to structures.
9. CD-2 should be added to sag/inlet location for construction duration and to prevent
ponding prior to final topcoat of asphalt. Alternate methods to drain ponding areas will
be considered.
10. R/W needs to be 1 foot behind sidewalks.
11. Pavement design for new subdivision streets shall be developed using the
VirginiaDOT.org
