My only questions is if the gas service line that is going to 490 Hillsdale would potholes and whether or not it is shown on the profiles to not be in conflict with the entrance to WAWA. I saw on the plans that the contractor is to field verify the depth of the line. I was just curious if we have more information as to whether or not it will need to be relocated during construction. Other than that I do not have any comments for the site. Response: A profile has been provided on sheet CU-501 that has been created from field test pits over the existing gas lateral. Based on the results, no conflict is anticipated with the existing lateral and it can remain in service throughout construction. Notes have been added for the contractor to contact Kimley- Horn if field conditions vary from the construction plans. ACSA Sheet CU-101: 1. Show 6" GV for tapping sleeve and valve. Response: A gate valve has been added and called out. 2. Show 4" GV to meter vault. Response: A gate valve has been added and called out. 3. Ensure proposed sewer lateral enters the existing manhole at a minimum angle of 90 degrees. Response: A label has been added to ensure a 90 degree connection at the existing manhole. Sheet CU-502: Kimlep Horn Page 2 1. Include the following construction details — TD-11 (Typical Service Tap Abandonment), TD-14 (Typical Meter Vault). Response: Details have been added to sheet CU-502. 2. Has the fire department advised if a second hydrant would be required to serve the site? Response: Per email and phone conversations with Howard Lagomarsino on 09/20/2021, only one new hydrant is proposed with this development. The existing hydrants along Greenbrier Drive and Seminole Trail will provided the required additional fire flow coverage to service the site. VDH 1. VDH still needs to send in their comments but they did have "no objection' to the initial plans so that is a good sign. Response: No comments have been received at the time of this submission. "n 1. Move the fire hydrant and water meter to a less visible location and add landscaping to provide more complete screening/integ ration. Response: Per confirmations at the ARB meeting on 11/15/2021, the hydrant remains were previously proposed. Additional landscape plantings have been provided around the hydrant to aid in screening the hydrant from the public right-of-way. 2. Revise the photometric plan using an LLF of 1.0 for all fixtures. Response: The LLF has been updated to 1.0 for all fixtures as requested. 3. Revise the finish for the parking lot lights (poles and fixtures) to bronze. Response: The parking lot lights have been updated to have a bronze finish as requested. 4. Add a street tree along Greenbrier west of the monument sign and add shrubs between Greenbrier and the 8- space parking row. Response: Shrubs have been provided between the 8 parking spaces and Greenbrier Dr. An additional tree has been provided along Greenbrier Dr., just west of the monument sign, in order not to block the visibility of the sign from Greenbrier Dr. 5. Add landscaping between the Greenbrier sidewalk and the new path connecting the sidewalk to the parking lot to compensate for the lack of trees in other required locations. Response: Low-level plantings have been provided on both sides of the new sidewalk. 6. Provide additional low- level planting along the Rt. 29 and Greenbrier frontages to offset visual impacts, compensate for smaller trees and help establish an overall coordinated landscape. Response: Additional low-level plantings have been provided along Route 29 and Greenbrier Drive. 7. Revise the Luminaire Location Summary to correspond to the 22' 11" maximum canopy height and make other corresponding corrections as necessary, while maintaining a maximum of 30 fc under the canopy. Response: Luminaire location summary has been updated to show fixtures under the 22' 11" maximum canopy height while maintaining a maximum of 30 fc under the canopy as requested. 8. Revise the photometric plan using an LLF of 1.0 for all fixtures. Reduce the illumination under the fuel pump canopy to a maximum of 30 fc. Response: The photometric plan has been updated to use an LLF of 1.0 for all fixtures as requested. The illumination under the fuel pump canopy has been updated to be a maximum of 30 fc as requested. 9. Revise the landscape plan to integrate the monument signs more fully into the landscape. Kimley>>> Horn Response: The Monument signs are fully integrated within the landscape beds, similar to other Wawa locations. Plannina 1. [Comment] Project number.

Slope appears to be steeper than 3:1 where it is labeled as 3:1. Response: Labels have been added and backchecked to ensure accuracy. See sheet CG-101. 7. Ensure landscaping that can withstand steep slopes is specified for the slopes steeper than 3:1. Response: Noted. Kimlep Horn Page 6 8. Ensure all proposed easements are shown. This includes a SWM facility easement around the SWM facility. This is separate from the public drainage easement around the out fall from the facility. Response: A SWM Facility easement has been added and labeled around the SWM facility. See sheet CS- 101 and CG-101. 9. Do you have permission to grade off site? It appears you are doing work on parcel 061 WO-02-00-002BO. Response: A permission statement from the adjacent owner will be provided prior to plan approval. 10. Per county code 18-4.12.17.a, vehicle access aisles that are not adjacent to parking spaces, shall not exceed a grade of ten percent. The entrance off Greenbrier Dr. appears to exceed 10%. Response: This site in constrained by several factors including, existing elevations and utilities that require a steeper access entrance off of Greenbrier Drive. A waiver has been submitted to allow design to be increased beyond the 10% County maximum. 11. Parking areas should not exceed 5% grade anywhere, in any direction. Response: Parking areas have been revised to ensure less than 5% grade in all directions. See sheet CG- 101. 12. Please show DEQ approval of remedial activities for the leaking underground storage tank and show any necessary notes on the plan for the contractor.

Also the SWM facility should be located so it doesn't impede the Greenbrier entrance if maintenance or replacement is necessary. Response: The SWM facility has been relocated away from the Greenbrier entrance. The SWM control structure has also been relocated away from the Greenbrier entrance. In order to outfall the site towards Greenbrier Drive, structure 100 remains within the middle of the travel way to avoid existing gas mains and proposed storm structures. Building Inspections Add the following note to the Utility notes on page CA-101: a. All water, sewer and fire lines require NEW inspection and testing procedures. The ACSA performs any testing and inspections of the public sewer and water main(s). The Albemarle County Building Inspections Department (ACBID) does a visual inspection and witnesses the testing of the building drain, water service pipe and the sprinkler lead-in connection. The developer/contractor is responsible to retain a Special Inspector as outlined in the updated Albemarle County Policy for Site Utilities to perform the visual inspection and testing of all utilities not covered by the ACSA or ACBID. This includes building sewers, water and fire line branches between the main and the meter(s)/building(s). The Special Inspector's report must be submitted and approved by the Albemarle County Engineering Department prior to a Certificate of Occupancy being issued. Response: The note has been added to sheet CA-101. Kimlep Horn Page 7 2. Three accessible parking spaces are needed per the VA USBC. Response: Two accessible spaces are provided as required for parking lots less than 50 spaces. The additional 20 spaces in the peripheral parking lot on the east side of the property are proposed as part of a shared parking agreement between the two property owners.

Structure 100 should not be in the middle of a travelway. Also the SWM facility should be located so it doesn't impede the Greenbrier entrance if maintenance or replacement is necessary. Response: The SWM facility has been relocated away from the Greenbrier entrance. The SWM control structure has also been relocated away from the Greenbrier entrance. In order to outfall the site towards Greenbrier Drive, structure 100 remains within the middle of the travel way to avoid existing gas mains and proposed storm structures. 5. Please show a SWM facility easement around the facility and a public drainage easement around the outfall pipes. Response: A SWM Facility easement has been added and labeled around the SWM facility. See sheet CS-101 and CG-101. Kimlep Horn Page 8 6. Per county code 18-4.12.17.a, vehicle access aisles that are not adjacent to parking spaces, shall not exceed a grade of ten percent. The entrance off Greenbrier Dr. appears to exceed 10%. Response: This site in constrained by several factors including, existing elevations and utilities that require a steeper access entrance off of Greenbrier Drive. A waiver has been submitted to allow design to be increased beyond the 10% County maximum. 7. Parking areas should not exceed 5% grade anywhere, in any direction. Response: Parking areas have been revised to ensure less than 5% grade in all directions. See sheet CG- 101. 8. Please show DEQ approval of remedial activities for the leaking underground storage tank and show any necessary notes on the plan for the contractor. Response: The approval will be provided prior to plan approval. 9. Minimum slope of storm pipes is 0.5%. Please revise the 0.10% slope.

Response: Storm pipe calculations with velocity and hydraulic grade lines have been added to sheet CG- 501 as requested. 11. Please provide routing and calculations for the SWM design. Response: Routing and calculations for the SWM design have been added to sheets CG-503 and CG-504 as requested. 12. Ensure the SWM facility has adequate access manholes at each inlet and at the outlet. Response: The SWM facility is an R-Tank system. The system is currently under design by ACF and more detailed specifications will be provided with the next submission. 13. [CG-201] Please clarify drainage areas and lines on the plan. Also, please clarify the bypass labels. Is there some area that does not flow to structure 98, your ultimate analysis point? If so, you must show compliance with channel and flood protection for those areas. Also, your narrative mentions offsite drainage, but does now show it on the plan. Response: The narrative on sheet CG-201 has been revised. No offsite drainage areas enter onto the property or underground detention system. The underground detention system proposed onsite outfalls through Control Structure 100A and ultimately ties into the existing stormwater conveyance system at structure 97. Drainage areas with a "DETENTION" label are areas that reach the underground system. As shown in the SWM calculations provided on sheet CG-503, there are areas within the limits of disturbance that do not flow towards the underground detention system. The system is sized to over detain the onsite flows to offset the "BYPASS" flows that leave the site. The post -development flows are reduced to the level required by the pre -development flows. See summary table that is provided on sheet CG-201. D. Erosion and Sediment Control Plan (ESCP) Virginia Code §62.1-44.15:55 requires the VESCP authority to approve or disapprove an ESCP. This plan is approved/disapproved, and the reasons are provided in the comments below. The erosion control plan content requirements can be found in County Code section 17-402. 1. Please provide a paved wash rack per the detail on page 8 of the County Design Standards Manual: https://www.albemarle.org/Home/ShowDocument?id=270 Ensure there is an area for water to settle out from the wash rack. Response: The paved wash rack detail has been provided on page ES-501. A settlement area has been shown on sheet CE-101. Kimlep Horn Page 9 2. Please show dust control as well as temporary and permanent seeding symbols on all E&S sheets. Response: Dust control and temporary/permanent seeding labels have been added to CE-101 and CE- 102. 3. [CG-101] Maximum slope allowed is 2:1. Grading appears to exceed this in a few places. Response: Acknowledged. Where proposed slopes approach 2:1, labels have been added labels to show compliance. See sheet CG-101. Additional ground covers have been provided on sheet CP-101 to provide additional support where steep slopes are proposed. 4. [CG-101 ] Please check 2:1 and 3:1 labels. Slope appears to be steeper than 3:1 where it is labeled as 3:1. Response: Labels have been added and backchecked to ensure accuracy. See sheet CG-101. 5. Please show permission for the offsite work. Sheet CE-501 mentions an easement. This plan cannot be approved until that is provided. Response: Permission for offsite work will be provided prior to plan approval. 6. Ensure applicable Albemarle County notes are included on your plans: https://www.albemarle.org/home/showpublisheddocument/l 262/637321325255330000 Response: The Albemarle County notes have been added to sheet CA-102. 7. [CE-101] Please show a stockpile location as well as a staging and parking area. Response: Stockpile, staging and parking areas are provided on both E&SC Phases. See sheets CE-101 and CE-102. 8. Extend perimeter controls around this area and adjust limit of disturbance if necessary: Response: Silt fence has been added to the referenced area. See sheets CE-101 and CE-102. Oe S 9. Please ensure you are addressing all runoff to the site. Is there any drainage coming from the parcel to the south? There are not sufficient contours on this plan to tell, however county GIS shows some offsite water may be draining to this site. This may affect drainage area to the trap, etc. Response: We have provided a drainage area map on sheet CG-203 that depicts a portion of the property to the south that flows towards the existing inlet on Seminole Trail. Based on field run topo information, the remaining area along the shared property line does not flow onsite the project site and it has therefore been excluded from the SWM design and calculations. 10. The side slopes of the dry storage and embankment of the sediment trap should be 2:1 or flatter. Plans currently show 1:1. Response: Side slopes have been added to the sediment trap on sheet CE-101 to ensure slopes no steeper than 2:1. Kimley>>> Horn Page 10 11. What is the purpose of this excavation shown below? Can it be part of the overall sediment trap? Response: The ultimate condition storm pipes are intended to be used to outfall the sediment trap to the existing stormwater conveyance system that continues down Greenbrier drive. Due to the depth of the proposed pipe relative to the existing ground surface in the area, the pipe outfall is shown separately from the trap itself. WADE RIPRAP OUTFALL WFT STORAGE: 453.50 12. Please ensure all sediment trap requirements in VESCH 3.13 are met. Embankment width, weir length, etc. Response: The proposed sediment trap meets the requirements of the VESCH detail 3.13.
