Commissioner August 29, 2014 Ms. Ellie Carter Ray Senior Planner County of Albemarle Department of Community Development 401 McIntire Road CharIottesviIle, VA 22902 Re: SUB - 2014 - 000126 Belvedere Phase IIB Preliminary Subdivision PIat Dear Ms. Ray: We have reviewed the preliminary subdivision plat for Belvedere Phase IIB dated 7.'21 `14 as submitted by Collins Engineering and offer the following comments: 1. The private versus public roads should be clearly labeled on the preliminary plat. 2. Phillips Alley is labeled at two separate locations on the preliminary plat. 3. The available sight distance for Belvedere Boulevard and Fowler Street should be shown on the preliminary plat. 4. The proposed ADT for Belvedere Boulevard should be added to the preliminary plat. 5. The typical sections for Farrow Drive and Colbert Street indicate parking on one side of the road only. The side that will be available for parking should be identified. 6. The typical section for Belvedere Boulevard indicates 12' travel lanes and 4' bike lanes. Will this be acceptable to Emergency Services in lieu of their 20' clear travel path requirement? 7. The proposed alignment of the roads shown on the preliminary plat have previously been reviewed and commented on by Joel DeNunzio in an e-mail dated April 6, 2012. These comments, which do not appear to have been addressed are summarized below: a. The section of road that will be the future connector road needs to be within the reserved 100 foot right of way as shown with the Belvedere Rezoning Plan. The Stormwater Management Facility should not be located within this reserved right of way. b. The future road should be designed to allow for construction by the County for the future construction to have minimum impacts on the subdivision and minimum reconstruction of the collector road. The County should only expect to reconstruct a small portion of the future collector road for the tie in's. c. The future collector road should not have multiple reverse curves throught this section to go around a stormwater management facility. This alignment will require this section of road to be constructed with superelevation and will complicate the future construction. d. Road G and Y (Colbert Street and Fowler Street respectively) need to have adequate horizontal curves. This item appears to have been discussed with the applicant in a meeting at the County office in 2012. This plan shows t- intersections that may not be constructed. The plan needs to meet the VDOT standards assuming the future road is not constructed. e. Access points to the section of the future road need to be in accordance with the VDOT Access Management Regulations for an Urban Collector Road with a minimum design speed of 35 mph. I would recommend that the design speed be set at 40 mph. f. I am attaching a sketch of what I would consider to be an acceptable design according to a meeting with the applicant in 2012. A design similar to the attached will minimize future demolition and reconstruction and meet the minimum requirements in the interim. The horizontal curves were set at 20 mph and we think this will be acceptable assuming the roads prior to the future collector have relatively low volumes. The curves will need to have adequate approach warning as shown in the VDOT Road Design Manual but minimizing the radius of curvature will also minimize the impact to the developable lots. The location of the collector road in the sketch will of course need to be adjusted to accommodate the necessary grading, but for the development's benefit, I would recommend placing as far back on the reserved right -of -way as possible. If you need additional information concerning this project, please do not hesitate to contact me at (434) 422 -9782. Sincerely, Troy ustin, P.E.
