RE: Response Letter #1 for SLTB2021-00159 Bamboo Grove Road Plan - Engineering
Dear John,
Thank you for your review of the Road plan for Bamboo Grove. This letter contains responses to County
comments dated October 27, 2021. Our responses are as follows:
1. C3
a. Provide/label speed limit sign.
Speed limit sign added near entrance.
b. Provide turnaround. Parking spaces are not part of the travelway width, or turnarounds
Small turnaround provided. Striping and signage now delineate this. Full size fire & rescue
turnaround not required due to the short road length.
2. C4
a. Show radius of curvature for PE entrance (at driveway entrance).
Private entrance radius labelled. Note that this is a "rural section" style driveway so no
entrance connection radii are needed)
b. Label driveway width at intersection with Bamboo Grove -ensure width > 12ft.
12' width labelled.
3. C4: Drainage structure A2 appears to lie partially within VDOT RW (Orchard Drive, Rt. 1206);
coordinate construction with VDOT
Noted, an MOT plan added to the road plans. This will guide culvert construction.
4. C5: Provide barricade, curb, or similar physical barrier to prevent vehicles leaving pavement
when reversing from perpendicular parking spaces. There needs to be a physical barrier between
paved surface and unbroken grade that falls to SWM facility.
Noted, a GR-2 guardrail has been added. Note that guardrail will stick out over the gravel -
vehicle wheels will not be able to traverse the gravel ditch. (VDOT guardrail detail omitted
due to new VDOT policy).
5. C3, C5: Label stone features (channels, diaphragm, SWM-related).
Stone SWM features now labelled.
6. C8: Provide pavement design 'owing 2" SM-9.5A with 6" VDOT 21A stone base is sufficient
for peak ADT.
Pavement design now provided.
