Re: North Pointe — Route 29 Improvements Plan (Lewis & Clark Drive)
SUB-2016-00196
Review #3
Dear Mr. Wentland:
The Department of Transportation, Charlottesville Residency Transportation and Land Use
Section and Culpeper District Traffic Engineering, Hydraulics, and Structure & Bridge Sections,
have reviewed the above referenced plan as submitted by Collins Engineering, dated 31 July
2017, and offer the following comments:
Traffic Engineering/Land Use
1. The proposed northbound right turn lane storage may be shortened to 200 feet.
2. The lane drop on Lewis & Clark must be marked in accordance with MUTCD.
3. The proposed U-turns should be designed to prevent traffic egression from the existing
entrances (at both the NB and SB sides) from being able to use it. The SB U-turn should
be shifted so as to not line up with existing entrances on Route 29.
4. The proposed Ieft turn lane for the U-Turn on Route 29 SB, should be offset to
accommodate future through lanes on Rte. 29; this change may call for a new Auto Turn
analysis for WB-65 or WB-67.
5. The Traffic Engineering Section will provide a sketch of how the Lewis & Clark Drive
approach to Route 29 should be designed, which will be forwarded to the applicant.
6. The note on sheet 3 concerning RCUT, North U-Turn, and South U-Turn should be
changed to "may be" and not "shall be", upon Traffic Engineering approval.
7. The proposed splitter island should be extended into the future through lane. We
acknowledge that this is different from previous comment but is based on updated
information from Traffic Engineering.
8. Under Traffic Control Notes, the allowable work hours for Route 29 are not accurate;
Copies of the allowable work hours can be provided, if needed.
9. Traffic control measures should be shown to scale on the proposed Layout & Striping
Plan, to reflect the proposed sequence of construction and their associated maintenance of
traffic. Preparer of the MOT plan must provide verification of completion of the VDOT
Advanced Work Zone Traffic Control Training.
10. Tubular markers are not to be used as channelizing devices on Rte. 29; barrels or cones
should be used instead.

Structure & Bridge
11. Previous comment incorrectly stated that the 2008 Virginia Department of Transportation
Road and Bridge Standards should be noted, it should be written such that the 2016
Standards are used. Please revise note 1.3 on sheet 1 I as follows: "Shall adhere to
applicable standards in accordance with 2016 Virginia Department of Transportation
Road and Bridge Standards; including all current revisions."
The following comments pertain to the proposed retaining wall plans that were provided on 19
September 2017.
12. The provided geotechnical report, dated 3/12/2010, does not provide enough information
to perform a comprehensive review of the wall system. The report states that 41 borings
were performed; however, no logs were included (the appendices of the report were not
included). The primary purpose of the borings was to determine where rock was Iocated,
particularly in the areas of the site where deep cuts are required. Therefore, the borings
appear to be basically auger probes (no Standard Penetration testing). It is indicated that
samples of the cuts were obtained for lab testing, but no results are provided.
13. The subsurface exploration for the proposed retaining wall must be performed in
accordance with the minimum guidelines as indicated in Chapter 3 of the Materials
Division's Manual of Instruction (MOI), which can be found at the link below.

14. Both the structural and geotechnical design of the proposed retaining wall design must be
performed in accordance with the applicable AASHTO Specifications.
15. Mechanically stabilized earth (MSE) walls must satisfy the Structure and Bridge
requirements, which can be found at the link below.

Please provide two copies of the revised plan along with a comment response letter. If further
information is desired, please contact Justin Deel 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.
