ZMA- 2010 -00005 Richmond Road Entrance
Judy,
I have reviewed the above referenced plan and have the following comments:
1. The right in only does not channelize traffic properly to adequately discourage an egress movement.
The design needs to be similar to the VDOT Road Design Manual, Appendix f, page F -90. A 50 foot
taper offset at 12 feet with a 25 foot radius should be constructed. Also, this entrance appears to be for
cars only and truck use needs to be restricted. The width should be 16 feet for cars. If this design
causes grading issues with the proximity to the building, the entrance can be moved up to 15 feet away
from the building.
2. Adequate signage in accordance with the latest edition of the MUTCD needs to be shown for a do
not enter condition for vehicles attempting to exit the parking lot on Route 250.
3. An egress from this site to Route 250 will likely cause weaving issues at the intersection of route 20
and Route 250. If the entrance is not designed properly to eliminate this concern or if VDOT finds that
vehicles are using this ramp as an egress, the department can revoke any issued entrance permits.
4. The internal cutoff of the circulation occurs close to the parking area and there is not adequate room
if stacking should occur within the entrance ramp. The internal circulation should be revised possibly to
direct traffic into the middle parking row instead of the row adjacent to the highway. If it is desirable to
minimize cut through traffic, the internal road can be blocked after the middle parking row and all traffic
can flow up the middle row to access either side of the parking lot or to the right for the exit.
5. The design shall be in accordance with the VDOT Road Design Manual, 2007 road and Bridge
Specs and the 2008 VDOT Road and Bridge Standards. Final construction plans will need to show
adequate details for the entrance dimensions, grade, and drainage.
6. A Land Use Permit will be required for any construction within the Route 250 Right of Way.
Please let me know if you have any questions.
Thanks
Joel
