Colin Engineering 200 Garrett Street. Suite K Charlottesville, VA 22902 RE: North Pointe Apartments Section 1E Phase A 1st Review Dear Scott Colins: The Albemarle County Service Authority (ACSA) has reviewed the above referenced site plan, dated 5/16/2022, and the following comments must be addressed prior to the plan being approvable to the ACSA. 1. The water and sewer improvements for North Pointe Section 1 must be dedicated to ACSA before this plan can be approved. 2. The offsite private sewer easement must be recorded prior to plan approval and the recordation information should be shown on the plans. The easement should encompass the private sewer, not stop at the edge of the ACSA easement. 3. A Flow Acceptance letter is required from the RWSA for this project. ACSA will request this from RWSA. Provide the anticipated schedule for full build -out of this site. 4. Provide plumbing fixture counts for each building so that the meters can be sized. 5. Provide a water data sheet. 6. On the cover sheet, modify the note for "Utilities" to reflect that water and sewer is provided by the Albemarle County Service Authority. 7. On the Utility sheets, add a note that all proposed sanitary sewer is private. 8. On waterline 1, relocate the fire hydrant near Sta. 16+00 to an area with more room. Possible locations would be the islands on the south side of the road. 9. At the 8"x6" tee for waterline 3 (it will no longer be a cross), show an 8" valve on both sides of the tee. 10. At the 8"x8" tee where waterline 2 connects to waterline 1 in Huntly Street, add an 8" valve on the northeast leg of the tee. 11. Shift waterline 1, from Sta. 20+00 to the end of the waterline, from Bentley Circle to the drive isle that is closer to Building 7. 12. Remove the air release valve from waterline 1. Shift the hydrant that is proposed in the island in front of the clubhouse so that the connection for the hydrant is at the high point in waterline 1. 13. Throughout the site, shift the location of the waterlines so that they are located in the center of a drive lane rather than the center of the roadway. 168 Spotnap Road — Charlottesville, VA 22911 — Phone (434) 977-4511 — Fax (434) 979-0698 www.serviceauthority.org 14. Revise the location and design of the proposed water meters and service lines based on the following comments: a. Separate the water service line from the fire line for all meters. The fire lines will be private after the gate valve at the tee off the main and therefore do not need to be in the ACSA easement. The water service should be a separate tap off the main. Remove the blow off assembly from the fire lines. b. Revise the meter location for Buildings I and 2 so that the meter is located in a more accessible location with no obstructions or structures in the easement. The meter should be located as close to the water main as possible. Consider placing the meter in an island in the parking lot, possibly co -located with the hydrant. c. Shift the meter location for Buildings 3 and 4 to the south so that the easement can extend 10' beyond the meter and not overlap with the building. On both sides of the tap for the water service (and fire line connection), add an inline gate valve so the meter can be served can be served from either direction. d. Revise the meter location for Buildings 5 and 6 so that the meter is located in a more accessible location with no obstructions in the easement. The meter should be located as close to the waterline 2 as possible. Waterline 4 should be eliminated. The hydrant in the island, the fire line, and water service can all be connected to waterline 2. Consider placing the meter in an island in the parking lot, possibly co -located with the hydrant. On both sides of the tap for the water service (and fire line connection), add an inline gate valve so the meter can be served can be served from either direction. e. Shift the meter location for Building 7 so that the meter is in the other side of the easement and further away from the building. On both sides of the tap for the water service (and fire line connection), add an inline gate valve so the meter can be served can be served from either direction. f. The F meter for the clubhouse should be served by a I" service line, not a larger line. Move the meter to out to the island or other greenspace closer to waterline 1. The fire hydrant in the island could be collocated in the same easement as the water meter. 15. An RPZ is required on the private side of every meter. These will be privately owned and maintained. 16. Show and label the DDCA for each fire line after the isolation valve. If these will be located inside the building, note that on the plans. If they will be installed in vaults, show the vaults on the plans. The vaults should be outside the ACSA easements. 17. The water pressure at the meters will exceed 80 psi. Private PRV's should be installed on private portion of the service lines or in the buildings. 18. The ACSA easements should extend beyond all appurtenances, including meter vaults and hydrants, a minimum of 10'. 19. On the waterline profiles, clarify that the 3" copper service is on the private side of the meter. The public portion of the service will be in accordance with the ACSA standard details. 20. Revise the callout for the meter size on the waterline 3 profile. 21. Revise the sanitary profiles as needed to provide 18" of vertical separation between the waterlines and the sanitary lines at all crossings. 22. On the waterline profiles, call out the separation between the two lines at all crossings if there is less than 3 feet. 23. Show the proposed ACSA easements on the lighting sheet. Move all light poles out of ACSA easements. 24. Move all trees and shrubs out of ACSA easements and a minimum of 10' away from all ACSA infrastructure. 25. Remove the following sheets from future ACSA submissions: 2, 3, 4, 14, 20, 24, and 25. Please include annotated responses to all of these comments with the next submission.
