The engineering comments regarding the initial site plan application for Old Trail Village Blocks 12 and
are provided below.
Comments to address for Initial Site Plan:
1. For the WPO application, I will review the bioretention basin from the Block 14 plans. Full
treatment for Blocks 12 and 15 should be met.
2. A sediment basin is necessary for the E &S of this site. Please clarify what will be used. If the
bioretention area from Block 14 will be used, provide a note stating when the conversion will
occur in the WPO plan.
3. There are proffers on driveway standards. It will be helpful if the proposed layout of all
townhomes and driveways can be shown on this plan to see if driveway standards, sight distances
from garages, and overlot grading works with the site. Also, please revise the grading plan. The
grading provided can be refined to reflect grading of townhomes. What's shown appears to be
mass grading.
4. The steep grading on Private Road "A" near lot 1 should be revised.
5. The zoning approval allowed for the use of alleys when lots front along a green space or common
amenity. According to the proposed plan, lot 14 does not front green space. Please address.
6. The type of temporary turnaround near lots 12, 13, and 14 has been problematic with other
approved plans. It has been used for parking spaces. Please connect road "A" to Glenn Valley
Drive to avoid the turnaround. This will also resolve comment 5 since green space can be provided
for lot 14.
7. Remove the temporary turnaround near lot 1.
8. Private Alley "A" and "B" have roll top curb and gutter, yet there are proposed DI structures. This
will not work. Please provide the transition from the roll top to full CG -6 for the DI's.
9. Lots 13 -18 do not meet the access requirements for fire rescue access if road "A" will serve as
primary access to lots. E/P to E/P should be 20' wide at a minimum.
10. It appears a waiver for the frontage road, private alley "A ", is necessary for planting strips and
sidewalks. Please discuss with planning.

11. Please show the planting strip and sidewalk on Fielding Run Drive, across from lots 9 and 19.
These items will be bonded as part of Fielding Run Drive.
Comments to address for Final Site Plan:
12. It appears there is grading within the stream buffer area. Please provide a mitigation plan.
13. A landscaping plan should be provided to show proposed street trees.
14. Provide VDOT roll top curb detail.
15. Provide pavement design for all roads.
16. It also appears the public roads do not match pavement detail. Please revise.
17. Show drainage easement from str 22 -22A and str 32 -32A.
18. Show sight distances.
19. Entrances shall be 4% grade for a distance of 40' from the intersected street.
20. Provide the sidewalk detail.
