Brich, P.E. Commissioner June 11, 2018 County of Albemarle Department of Community Development 401 McIntire Road Charlottesville, VA 22902 Attn: Christopher Perez Re: Rivanna Village Phase II — Final Site Plan SDP-2018-00031 Review #1 Dear Mr. Perez: The Department of Transportation, Charlottesville Residency Transportation and Land Use Section, has reviewed the above referenced plan as submitted by Alan Franklin PE, LLC, dated 24 April 2018, and offers the following comments: I. Oversized structures, such as the proposed arch bridges, will only be approved if a maintenance agreement is recorded with the County of Albemarle. If VDOT is to maintain these structures, their sizes must be hydraulically justified. 2. Regardless of maintenance, arch bridges, box culverts, and retaining walls that are located within the ROW or- support structures within the ROW must be approved by the Culpeper District Structure & Bridge Section, as well as the Culpeper District Hydraulics Section prior to permit issuance. A maintenance agreement with the County/HOA for retaining walls located in or supporting structures within the ROW should be recorded prior to street acceptance. Comments from the Structure & Bridge and Hydraulics Sections will be forwarded as they are received. 3. Also concerning the arches, box culverts, and walls, a Geotechnical report is required including borings at each end wall. Borings must be performed in accordance with Chapter 3 of the VDOT Manual of Instructions (MOI). 4. Excessive right-of-way should not be granted for the purposes of having utilities. The right-of-way line should be I foot beyond the sidewalk. 5. Where DI-3s are greater than 8 feet deep, DI-3AA, -3BB, or -3CC should be specified as applicable and those details should be provided. The 9' requirement is for DI-2s. 6. The Drainage Manual states that pipe velocities that exceed 10 fps are to be avoided. 7. PIease show HGL's on profiles. Also provide HGL calculations, which should be consistent with existing plans showing existing structures that are being tied in to. 8. Typical Sections; pavement materials should be daylighted to the shoulder/slope, not abruptly terminated as shown. The pavement materials on the typical sections do not appear to have changed from the previous submission. 9. The Route 250 Improvements typical sections call for 2" of SM 9.5; as previously noted, the maximum lift thickness for SM 9.5 is 1.5". 10. Please provide the Route 250 Improvements on a single sheet, or two, fully dimensioned. VirginiaDOT.org WE KEEP VIRGINIA MOVING June 11, 2018 Christopher Perez Page 2 11. Why does the Lazy Branch Lane section decrease to 29 feet f/c to f/c? The roadway section should remain consistent throughout. This decrease in section width is not reflected in the typical sections. 12. PIease callout arches on layout plans, including dimensions. Note that design plans for only one of the three proposed arches has been provided. 13. It would be preferable to aid in and quicken the review process if the plans were scaled to a smaller scale. Note that the Department only requires that scales be 1":50'. 14. If the resubmission is printed and scaled to an architectural paper size, the Department will require hard copies to review. 15. Show the required area of mill and overlay on Route 250. 15. Provide pavement design calculations. 17. Please include the attached Construction Notes on the plans. 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. Sincerely, a6m, Adam J. Moore, P.E.
