Pat Lawrence,
We have reviewed the above plan and have the following comments:
Profiles for the entrances are needed to show that the requirements for the CG -11
standard have been met.
Typical sections with pavement designs for the Rte 250 right turn lane need to be
shown. As stated on note 7 of the CG -11 standard, the pavement design for the
right turn lane and the entrance up to the proposed VDOT right -of -way line must
at least match that of the mainline pavement. The pavement design of Route 250
at this location is the following:
• Surface: 1.5" of 9.51)
• Base: 6" of BM 25A
• Subbase: 6" of 21B
The required intersection sight distance for Rte 250, a 4 lane divided major road
with a design speed of 45 mph, is 580' according to the VDOT Minimum
Standards of Entrances to State Highways. On sheet 4 the left sight distance line
at the Rte 250 entrance is only 500' long. A sight distance line to the right side at
this intersection is not shown. Sight distance lines also need to be shown for the
Pantops Park Dr. entrance.
There is an existing DI -313 drainage structure on the northeast corner of the site
which is not shown on topographical survey. These plans must show all existing
and proposed drainage structures. Drainage computations also need to be
submitted.
We also have the following notes which should be considered:
In the near future. Flow Automotive will be constructinL, a right turn lane that will
connect to Crown BMW's right turn lane. Coordination between these two
construction projects is highly encouraged to produce a smooth, continuous right
turn lane.
The Countv may reauire that the west side of the site along Pantops Park have
sidewalk and ramps.
If you have any_questions regarding the above comments, please contact Joel DeNunzio
or me_
