With the connection to two roads that are posted 45 mph, a posted speed limit of 25 mph with an ADT of 8,900 vpd may be low. Response 4: As discussed, reasoning behind design speed of 30 mph is to increase safety due to the numerous entrances coming out of commercial development, pedestrians using sidewalks and crosswalks, and horizontal and vertical road geometry. Comment 5: There is a note on the plan view (sheet 4A) that the design of the roadway is based on GS-7, Urban Collector with a design speed of 30 mph. There are several aspects of the GS-7 that need to be corrected in these plans: a. The minimum radius at 30 mph is 251 feet. The center line radius appears to be 249 feet. b. At 30 mph with a minimum radius of 251 feet, the road section should have a 4% superelevation. Per TC-5.11, in order to have a normal crown at 30 mph, the minimum radius needs to be 333 feet. Refer to TC-5.11 ULS in the 2008 Road and Bridge Standards. c. A minimum of 200 feet stopping distance needs to be provided based on a design speed of 30 mph. The street trees along Bent Creek Parkway between stations 14+00 and 18+00 may impact this requirement. In addition, any parking in the vicinity of this horizontal curve outside of the right-of-way will need to be considered as well. d. The plans indicate that the lane width will be 11 feet. However, note 1 on GS-7 indicates that if the ADT exceeds 2000,the lane width is to be 12 feet. Response 5: a. As discussed, the minimum radius of the centerline has been revised to 273 feet, per ULS Standards. b. Road geometry has been revised to ULS standards. Minimum radius is now 273 feet, therefore a 2%superelevation has been provided. Please see Sheet 5A. c. A note has been added to the Plan stating that the proposed street trees will be limbed up to eliminate sight distance concerns. Please see Landscape Sheets 9A-C. d. Lane widths have been revised to 12'.Please see Sheet 4A. Comment 6: The guard rail warrants need to be provided. In addition, the guard rail location shown be shown on the typical sections. Response 6: Guard rail is shown on typical sections and guardrail warrants have been provided.Please see Sheets 13A-B. Comment 7: Warrants for the turn lanes need to be provided for review. Response 7: Warrants have been provided by the traffic consultant prior to this submission for review. Comment 8: The lane transitions are shown to be 165'. This is based on 11' wide lanes. This needs to be revised based on 12' lanes. Response 8: Lane transitions have been revised based on the 12' lanes. Please see Sheets 4A-C.

In addition, the street trees along Bent Creek Parkway appear to be in conflict with the sight line for this entrance. Response 9: A sight easement has been provided. In addition, a note has been added to the plans stating the street trees will be limbed up to eliminate any sight distance concerns. Please see Sheets 9A-C. Comment 10: The turn lane warrants need to be provided for review. Response 10: Please see response to Comment 7. Comment 11: A sight easement needs to be provided for Entrance 3. In addition, the street trees along Bent Creek Parkway appear to be in conflict with the sight line for this entrance. Response 11: A sight easement has been provided. In addition, a note has been added to the plans stating the street trees will be limbed up to eliminate any sight distance concerns. Please see Sheet 9B. Comment 12: On Sheet 4B, there is a note indicating that the taper for the left turn lane for Entrance 3 is 100', however, the taper scales to approximately 65'. This should be revised to meet the minimum taper length. Response 12: The taper for the left turn lane at entrance 3 has been revised to 100'. Please see Sheet 4B. Comment 13: If the temporary turn around shown at station 33+50 will become a permanent entrance, it will need to be constructed to commercial entrance standards including minimum radii of 25'. If the turnaround will be removed, I would recommend the curb and gutter end at structure D-13 and extended toward Avon when Bent Creek Parkway is extended. Response 13: Entrance has been revised and designed to the commercial entrance standards including minimum radii of 25'. Please see Sheet 4B. Comment 14: The plans need to be clarified to clearly indicate the end of VDOT right-of-way. Currently,the same line type is shown throughout the road plans for the right-of-way. Response 14: Right-of-way has been revised to clearly distinguish between VDOT right-of-way and county reserved right-of-way. Please see Sheet 4C. Comment 15: It is our understanding that the roadway from station 34+00 to Avon Street Extended, including the park and ride,will be privately owned and maintained. Response 15: Yes, the roadway from 33+97 to Avon Street Extended, including the park and ride will be privately owned and maintained. Comment 16: The connection to Avon Street Extended shown on the profile on Sheet 6C should be a vertical curve. Response 16: The Bent Creek Parkway profile has been updated to include a vertical curve at the connection to Avon Street Extended. Please see Sheet 6C.

Therefore it is not the intention of this sight distance to meet minimum standards. Sight distance 9 has been revised to sight distance 8 in this submission. Please see Sheet 7E. Comment 20: The street trees as shown appear to conflict with the sight lines of several of the entrances and as previously mentioned, may interfere with the stopping sight distance through the horizontal curve between station 14+00 and 18+00. Response 20: A note has been added to the Plan stating that the proposed street trees will be limbed up to eliminate sight distance concerns. Please see Landscape Sheets 9A-C. Comment 21: The street trees along Avon Street Extended need to be located at least 30 feet from the end of the radius as indicated in Appendix B(1)of the Road Design Manual. Response 21: Street trees have been revised to be 30 feet from the end of the radius of Avon Street Extended. Please see Sheet 9C. Comment 22: VDOT maintenance of the storm sewer system will end at the structures located within the dedicated right-of-way. Response 22: Comment acknowledged. Comment 23: Notes need to be added to the storm sewer profiles indicating that standard steps (ST-1) will be require on all storm structures with a depth of 4' or greater and that safety slabs (SL-1) will be required on all storm structures with a depth of 12' or greater in accordance with the 2008 Road and Bridge Standards. Response 23: As requested,notes have been added to the storm profiles. Please see Sheets 11 A-J. Comment 24: The invert of structure B-3 from structure B-11 is lower than the invert out of structure B- 3 on the profiles labeled "Proposed Storm Profile — (B-1 to B-9) and "Proposed Storm Profile—(B-3 to B-11)". Response 24: The inverts have been revised. Please see Sheet 11B.

I'm not entirely sure how this will be installed and any necessary maintenance is going to be problematic. It appears that this structure and structures C-2, C-3, and C-5 could be removed and runoff from the road could run to structures D-14 and D-13. The lengths of these structures could potentially need to be increased. Response 26: As discussed, Structure C-2 is needed to outfall the Landfill BMP pond at the water surface elevation of the wetland area at the bridge crossing. Comment 27: There appear to be some discrepancies between the hydraulic calculations and the storm sewer profiles. While none of the discrepancies appear to make the design inadequate,the calculations and profiles should match. Segments noted, but not excluded to, are F7-F6, F6-F5,F5-F4, G6-G5, G5-G4, G4-G3,and G3-G2. Response 27: Calculations and profiles have been revised to match. Please see Sheets 11J.

Revise. Response 4: The SWM and BMP design has been shown in a separate WPO Plan. Comment 5: [32.5.2 (d)] Indicate with shading those areas of the site where existing slopes are critical slopes. Response 5: The erosion and sediment control design has been shown in a separate WPO Plan (Phase I) for the site. That plan shows the existing critical slopes and which will be preserved or disturbed. Comment 6: [32.5.2 (e)] Label all the existing wooded areas and provide a general description of the type of of trees(ie deciduous, evergreen, or mixed). Response 6: A label has been added to the existing wooded areas describing the type of trees. See the landscape plans, Sheets 13A— 13J. Comment 7: [32.5.2 (i); 32.5.2 (n)] Provide the material type and dimensions for the shoulder along Bent Creek Road. Response 7: The shoulder along Bent Creek Road has been removed. A separate road improvement plan for Bent Creek Parkway has been submitted which proposed an urban condition with curb and gutter.

Comment 13: [32.5.2 (p)] Provide on a landscape sheet the conservation plan checklist. Response 13: The conservation plan checklist has been shown on Sheet 14A. Comment 14: [32.5.2 (p)] A waiver for the requirement of street trees needs to be provided for the minor variation in accordance with Section 32.3.5 (b). Staff would like street trees to be provided all along Bent Creek parkway where possible. This will also be a factor when reviewing the request in Comment#18. Eliminating the gravel shoulder and putting in an urban section of road will allow room for street trees. Response 14: Street trees have been provided along Bent Creek Parkway. These trees are shown with the Road Improvement Plan for Bent Creek Parkway. Comment 15: [32.7.9] Show the right of way lines on the landscape plan. Trees shall be located within the right of way where feasible. Response 15: The right-of-way lines have been shown on the landscape plan.

Response 18: A waiver is no longer required as the roadway has been designed as an urban section. Comment 19: [Proffer#1-G] See comments from CAT regarding the park and ride lot and transit stops. Coordinate the location of all transit stops with CAT. Response 19: Acknowledged. The developer shall coordinate with CAT as the project develops for the location of all transit stops within the shopping center. CAT Options: Option 1: We believe this option would better serve the shopping center and allow passengers better access to the locations. However, it does entail going through the facility rather than going around it. Questions we had were if the parking spaces that are marked with squares can be converted into bus pull outs/stops. Additionally, we were not sure if the circle is capable of handling a 35 foot bus. Option 2: There are 2 locations I see possible for bus stops. The western stop would be located and what seems to be a pavilion/entrance. However, because the location is right after a turn, it might have to be pushed further north. The eastern stop would have no issues if a cut out can be built into the median there. Additionally, stops will have to be put on the opposite of each stop to serve in both direction. Department of Community Development: A. Application Information Comment 1: Please identify special use permit number (SP2012-00029) in "floodplain special use permit"on sheet 1. Response 1: A reference to the special use permit for the floodplain has been added on Sheet 1.

The RWSA Moores Creek Interceptor is located adjacent to the north creek bank along the entire project site, and erosion has been observed since the interceptor was constructed in 1974. RWSA is concerned that the stormwater design shown on the plans may exacerbate existing erosion conditions and as a result, undermine the stability of the sewer line. Of particular concern are structures STM D1 (sheet 10C) and STM D9 (sheet 10D), both of which may substantially alter stream flow patterns. Please provide documentation on how you intend to mitigate velocity and channel modifications caused by outfalls which would cause erosion on the north side of the creek. Response 1: A separate stream mitigation plan is currently being designed by Draper Aden and Associates for the Moores Creek strem mitigation efforts required with the approved proffers. Comment 2: Sheets 9A and 9E show connections to both City of Charlottesville and ACSA water lines. RWSA is currently developing a wholesale master metering program to monitor urban water usage by the City and the County. Further details on the program will be forthcoming; however it is likely that a meter and vault to be owned and operated by RWSA will be required at the interconnection. Exact details may be coordinated through future site plan work. Response 2: Acknowledged. Landscape Plan(Sheet 11A): Comment 1: On sheet 11A, portions of the "tree conservation" areas intersect the existing RWSA sewer line easement.
