Brich, P.E. 1401 East Broad Street Commissioner Richmond, Virginia 23219 January 17, 2022 County of Albemarle Department of Community Development 401 McIntire Road Charlottesville, VA 22902 Attn: Kevin McDermott Re: North Fork Residences — Rezoning Request ZMA-2021-00016 Review # 1 Dear Mr. McDermott: (804) 7862701 Fax: (804) 7862940 The Department of Transportation, Charlottesville Residency Transportation and Land Use Section, has reviewed the above referenced plan as prepared by Timmons Group, dated 13 December 2021, and offers the following comments: Comments on the Traffic Impact Analysis: a. Appendix A i. Can you please provide signed copies of the pre scope of work meeting documents? ii. Can you please ensure internal allowance/capture is checked on the scoping form? b. General i. Is there a reason why Berkmar Dr and Towncenter Dr were not included as study intersections? ii. Is there a reason why Connor Dr and Timberwood Blvd were not included as study intersections? iii. The agency has yet to adopt the 1 Ith edition of the ITE Trip Generation Manual; latest approved edition is the loth edition. All trip generation must use the loth edition. iv. The agency has yet to adopt SIDRA 9 and thus SIDRA 8 is the currently approved version for analysis. All round -a -bout analysis must be compatible with SIDRA 8. c. Page 13 - Towncenter Dr is 35mph between Dickerson Rd and Berkmar Dr and 25mph between Berkmar Dr and Route 29 d. Page 18 (Figure 2-2) - Brianwood Dr/Boulders Rd/Seminole Trail intersection (intersection 5) VirginiaDOT.org WE KEEP VIRGINIA MOVING January 17, 2022 Attn: Kevin McDermott e. Is there a reason for the storage lane reductions from the Existing to Total scenarios? f. Page 1-2, Data Collection — was there any adjustment made in the traffic volume due to COVID-19 pandemic? Please add a sentence here to inform the readers. (I saw in the later part of report, it was clarified that no adjustments were made for pandemic. Still I would recommend clarifying it in the Executive Summary.) g. Figure 2-1 — Per Google Earth, SB leg of Lewis and Clark Dr and Quail Run intersection has two through lanes. However, Figure 2-1 shows only one through lane on this approach. Please revise or confirm if there is only one through lane currently in the field. h. Figure 2-1 — Per Google Earth, SB leg of US 29 and Timberwood Blvd intersection seems inconsistent to Google Earth. Please revise or confirm if the lane configuration shows the current field condition. i. Update the Synchro Models if there's any changes in lane configuration based on the comments on Figure 2-1. j. Exiting Condition Synchro Models: All conditions should be analyzed with the provided signal timing details; optimized iterations can be recommended as separate mitigation conditions. This process helps better gauge the extent of impact in comparison with the submitted alternative i. US 29 and Towncenter Dr: Per the signal timing plan, Phase 3 (WBTL) has minimum green of 6 sec. But the model existing condition models currently have 5 sec. Please revise. Yellow and All -Red time in the existing condition models do not match with the timing plan for all phases. Please revise to make sure all phases have correct Yellow and All -Red times. Also revise the minimum splits accordingly. ii. US 29 and Timberwood Blvd: Please make sure Yellow and All -Red times in the existing condition models match with sign plan provided. Revise the minimum splits accordingly, when applicable. iii. US 29 and Lewis & Clark Dr: Please make sure minimum green, yellow, and All -Red times in the models matches with the sign plan provided. Revise the minimum splits accordingly, when applicable. iv. US 29 and Boulders Rd: Please make sure Yellow and All -Red times in the existing condition models match with sign plan provided. Revise the minimum splits accordingly, when applicable. k. Please make sure the models for background and total conditions are also updated based on the above comments on existing condition models. 1. Table 3-3 — Should it be "HCM" 95th percentile queue length instead of "HCS"? (This comment also applies to Table 5-1, Table 6-1, Table 7-1, Table 9-1, Table 10-1, and Table 11-1). in In many cases, the 95th percentile queue lengths are significantly different than the simulated maximum queue lengths. Please explain why? Which queue lengths are more representative of the existing field conditions, 95th percentile queue lengths or simulated maximum queue lengths? n. The number of trips from the proposed development (when complete) appears to be different on Page 1-1 and Page 8-1. Please revise or explain. January 17, 2022 Attn: Kevin McDermott o. Page 12-1, Section 12.1, Paragraph 1 states that "The intersections of US Route 29 with Airport Road/Proffit Road and with Boulders RoadBriarwood Drive operate with significant delay during the PM peak hour and create operational issues for adjacent intersections." Please clarify how it creates operational issues to adjacent intersections. 2. 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. Please provide a digital copy in PDF format of the revised plan along with a comment response letter. If further information is desired, please contact Doug McAvoy Jr. at (540) 718-6113.
