d. Label angle of intersections. nle appears to be less than 80 here
ii
Response: While the angle is less than 80 degrees at this intersection, this angle of
intersection would only impact emergency vehicles coming into the site and turning
left. However, emergency vehicles would not enter the site and turn left out of the
site, rather, they would enter the site and go straight or right. The angle of less than
80 degrees would only impact the left -out maneuver, which would not occur.
e. Streets and alleys must have temporary turnarounds. [14-410 C]
Response: All proposed roads now have a temporary turnaround. Road B has been
revised.
f. Provide cul-de-sac design. T-type turnarounds are discontinued. [ACDSM, p.20]
Response: Cul-de-sac are not necessary for this project. The roads are within the
150' requirements of the fire & rescue department and lots 1-8 would be accessible
from Proffit Road. Please refer to SUB2021-124.
g. Provide minimum 30' R/W access for the roads.
Response: For these private streets, a private access easement is provided, exceeding
30'.
h. Confirm ADA requirements for parking & access are met.
Response: Comment received. Per U.S. Access Board regarding ADA requirements,
ADA does not apply to individually owned housing in the private sector, which
would be the condition following subdivision approval.
i. Show dumpster pad(s) & details. [18-4.12.19)
Response: Each unit will be served by a trash -toter.
4. Sheet 10 -Show ex. san crossing separation between A9 & A9A and A9 & A8.
Response: Comment received. The existing sanitary pipe is now shown on these profiles,
showing adequate separation.
5. Sheet 11 - Show station where streets intersect.
The intersection stations are now shown on sheet C5 & C11.

6. Sheet 12 - Tree near Al2 will need to be moved outside drainage easement.
Response: The landscape plan has been revised to locate trees mostly outside of the
drainage easements. There is one instance where the tree must be located within the
drainage easement (near Str. A9a) due to street tree requirements and it is located a
minimum of 5' from the storm pipe to ensure that there will not be conflict.
Sheet 15 - Provide minimum 2.5" of BM-25. [VDOT Pavement Design Guide, Apx. Ill]
Response: Comment received. This detail has been updated.
8. Easement plat recordation required prior to ESP approval.
Response: Comment received.
