Review #2
Dear Mr Reitelbach:

Fax: (804) 786,2940
The Department of Transportation, Charlottesville Residency Transportation and Land Use Section, has
reviewed the above referenced plan as submitted by Bottler, dated 17 August 2020, and find it to be
generally acceptable. The following items will need to be adequately addressed prior to site plan
approval:
1. The access plan shown is reliant on the acquisition or encumbrance of land owned by the
Commonwealth of Virginia". Has the developer contacted VDOT's Right of Way division to
begin the process of surplus property evaluation?
2. Traffic Impact Analysis (TIA) comments :
Synchro Files:
• Build AM plan has split timings that do not match the existing coordination split timings plan. As
stated in the previous set of comments in response to the I" submittal, if signal -timing
modification is deemed necessary to accommodate the development, the modified signal timings
should be added to the recommendation section for review. Furthermore, any signal timing
modification to this intersection may require updating the entire coordination system along US 29
corridor.
• For the Build PM model:
o The TIA states the following as one of the recommendations for the southbound left
movement "Increase the maximum split for the southbound left -turn movement in
the PM peak hour from 20 seconds to 30 ". The TIA did not state that this increase
of the SBL split timing would decrease the signal split timing for northbound
through movement on U.S. 29 by 10 seconds (from existing 90 seconds to
proposed 80 seconds). Decreasing the green bandwidth for northbound US. 29
leads to creating additional delays and building longer queues for northbound
U.S. 29 during the PM peak. Furthermore, any changes to the signal split timing
at this intersection would skew the offset time for upstream and downstream

intersections and skew the coordination plan. If the developer desires to change
the signal timing at this intersection, traffic signal coordination models and
analysis for the entire corridor of U.S. 29 need to be developed and submitted to
VDOT/ Culpeper District Traffic Engineering and Staunton Traffic Operation
Center for review and approval. In addition, the modified coordination plans need
to prove that the signal operation would have sufficient green bandwidth to
accommodate the traffic volume along the entire corridor.
o Alternatively, maintaining the existing split timing, clearance interval and offset
leads to a 95 a percentile queue of #332-ft; as a result, the southbound left turn
lane needs to be extend to a minimum 350-ft to accommodate the length of the
queue without spilling over U.S. 29.
3. Note that the final plan must show conformance with the VDOT Road Design Manual
Appendices B(1) and F, as well as any other applicable standards, regulations or other
requirements.
If further information is desired, please contact Max Greene at 434-422-9894.
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.
