Review #1
Dear Mr. Anderson:

The Department of Transportation, Charlottesville Residency Transportation and
Land Use Section, has reviewed the above referenced plan as submitted by
Roudabush & Gale, Engineering, dated 15 September 2021, and find the
following:
1. Please remove trees within 30' of intersections per 13(1)-44 RDM.
2. 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. The HOA will be
responsible for the maintenance of sight lines.
3. 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. It's
recommend that velocities be adjusted accordingly.
4. For step down manholes located in the VDOT right of way that require
manhole bottom protection (e.g., additional concrete, steel plate, etc.),
bottom protection designs shall be submitted for VDOT approval prior to
fabrication.
5. CG-12 design appears to be from the commercial entrance detail (Heavy
Truck Traffic Anticipated) or the method of installation on radius pages of
VirginiaDOT.org

the Road & Bridge Standards. Please utilize Type A (With Buffer) or Type
C (Perpendicular) application.
6. Temporary turn -around or cul-de-sac's are required per Road Design
Manual Appendix B, page B(1)-25. See details for minimum lengths.
7. Please verify inlet #106 is placed in the lowest point of the sag so no
ponding will occur.
8. Storm MH #144 should be moved out of the roadway prism.
9. San. Sew. MH #4 appears to be in the curb/gutter and should be moved out
of the roadway prism.
10.Every effort should be made to minimize manhole installations at street
intersections and in the normal wheel path of the travel lanes.
11.Please show and label the cross drains in plan and profile and where they
will be attached or day lighted to drain. Please see UD's and CD"s in the
Road & Bridge Standards, Section 108.
12.Stop signs appear to be missing or in the wrong locations. Please review
the stop sign locations for through traffic design.
13.Please show the mail boxes & cluster box units per RDM Appendix B(1)
14.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.
