Thank you for your comments dated July 16, 2021 on the above referenced project. Below are our responses to the remaining
comments on the road plans.
Planning
1. The cover sheet legend has been updated for the storm pipe descriptions and the flow arrows have been added
to the grading and drainage plan.
Engineering
1. A WPO plan has been submitted to Albemarle County for review and approval.
2. As noted, a subdivision of this property is not being proposed. No new roads are proposed with this
development. The project only consists of private travelways.
3. Turn -around areas have been added to the plans at buildings 1 and 6, as requested.
4. The grading and drainage plan (and WPO plan) includes the connections to the Walgreens stormwater
conveyance systems.
Fire & Rescue
1. The signs and the spacing have been updated to meet requirements for Fire/Rescue.
2. The fire flow has been added to the cover sheet, as requested.
3. The available fire flow has been added to the cover sheet.
4. The fire hydrants have been added to the utility plan and meet the spacing requirements.
S. The FDC locations have been shown on the utility plan and a fire hydrant has been located within 100 feet of the
FDC on each building.
VDOT
1. Attached is the turn lane warrants for a left turn and right turn into the development. The current AADT does
not warrant left or right turns into the development.
2. The mid -block crossing has been removed. Current AADT on the road does warrant this mid -block crossing and it
has been removed.
3. Curb and gutter has been added along the frontage of the development on Worth Crossing. It stops at the
entrance where the future round -about will be installed. The entrance into the site has been updated with the
proposed curb and gutter design along Worth Crossing.
4. The curb and gutter transitions have been added to the plans.
S. The CG-12's have been updated to meet VDOT standards.
6. CG-11 design is not proposed at the entrance.
7. The entire shared use pathway is located within the Right of way and will meet VDOT standards.
8. The existing offsite drainage has been raptured with the proposed drainage design and conveyed through the
site within the drainage system.
9. The landscaping has been added to the development.
10. The location of the directional signs have been updated to avoid the existing structures.
11. The utility work and mill/overlay has been added and shown on the site plan.
12. This comment is acknowledged.
13. Attached is the comment response letter.
14. This comment is acknowledged.
Transportation
1. The sidewalk has been designed within the VDOT right of way.
2. The CG-12 has been added to the plans, as requested.
3. These are travelways, not roadways. The interior circulation is along the fronts of the buildings
4. This is a VDOT entrance and must conform with VDOT guidelines. Furthermore, the trips in and out of the site
are 528 Trips per day, and this does not warrant traffic calming devices within the development.

PHV APPROACH TOTAL, VEHICLES PER HOUR
FIGURE 3-26 WARRANTS FOR RIGHT TURN TREATMENT (2-LANE HIGHWAY)
Appropriate Radius required at all Intersections and Entrances (Commercial or Private).
LEGEND
PHV - Peak Hour Volume (also Design Hourly Volume equivalent)
Adjustment for Right Turns
For posted speeds at or under 45 mph, PHV right turns > 40, and
PHV total < 300.
Adjusted right turns = PHV Right Turns - 20
If PHV is not known use formula: PHV = ADT x K x D
K = the percent of AADT occurring in the peak hour
D = the percent of traffic in the peak direction of flow
Note: An average of 11 % for K x D will suffice.
When right turn facilities are warranted, see Figure 3-1 for design criteria.'
