Review #1
Dear Mr. Yauger:
The Department of Transportation, Charlottesville Rsidency Transportation and Land Use
Section has reviewed the above referenced plan as submitted by Bohler Engineering, revised 11
November 2019, and offers the following comments:
1. At station 16+50 newly proposed DI-3 Inlet Top; could the manhole on the south side of
the road be relocated to the proposed grate inlet location? This would also allow for the
level spreader to be connected through pipe crossings and remove the proposed flume.
The existing drainage culvert must be crossed at some point regardless. This also allows
for removal of the elbow (change of pipe directions should take place at an accessible
manhole).
2. At station 22+90 the structure and elbow must be moved outside the travel lane. This
could be moved to the median or outside the travel way.
3. Non-standard drainage items, if necessary to remain, must be more fully detailed
(elbows, flumes, etc.). Non-standard items require perpetual maintenance land use
permits.
4. Cross sections should show the existing and proposed grades (at minimum).
5. There are numerous cross section grade breaks greater than the 4-5% recommended by
AASHTO.
6. Why is there a grade break to the opposite direction for the turn lane? It can be at a
flatter slope than the existing lane, but it is not clear why it must transition so sharply
here.
7. It appears that there are through lanes proposed in a crowned section with slopes greater
than 2%. Why is this (in particular with the centerline curvature)?
8. If Polo Grounds is being reconstructed why does the new left turn lane go from 3.98° o to
2.65% then back up to 3.6%? Similar issue in both directions, not gradual and smooth.
9. Parabolic curves are necessary and should be noted where flow line drainage is to be
accommodated.
10. The shared use path, signal pole, and control cabinet have changed locations. Please
update the plans accordingly.
11. There are insufficient details on the plans regarding guardrail elements and required
dimensions (shoulder widths, MASH standards). Please coordinate guardrail plans with

VDOT prior to installation as some may be able to be removed while other areas may
need additional grading.
12. The cross sections refer to a proposed right turn lane when it appears to be a left turn
Iane.
13. Culvert B60-61 appears that it may be oversized. Could a smaller drainage section work
here?
14. Please note that other areas in the Polo Grounds roadway plans will need to be reviewed
for existing cross slope compatibility with current design. Recommend cross sections
showing existing vs. proposed roadway improvements every 25 or 50 feet.
15. Please schedule a field meeting with this office to discuss the plan submission.
Please provide two copies of the revised plan along with a comment response letter. If further
information is desl red, please contact Joel Kauppila at 434-422-9373.
A VDOT Land Use Permit will be required prior to any work within the right-of-way. The
owner/developer must contact the Charlottesville Residency Transportation and Land Use
Section at (434) 422-9399 for information pertaining to this process.
