cannot locate. (Rev. 2) Addressed.
11. Provide pavement design based on full build -out ADT. (Rev. 1) Not addressed. Applicant response (Rev.
1, 2): `Acknowledged. Pavement design will be provided when available.' (Rev. 2) Not addressed.
Comment persists. (Rev. 3) Partially addressed. As follow-up: If full build -out ADT listed on plans, please
explain where. Confirm total build -out ADT < 11,000, which appears approximate upper limit for proposed
heavy duty asphalt pavement section. See plan sheet C1.1, attached .xls & VDOT Pavement Design Guide.
If ADT >11,000, provide pavement design sufficient to meet proposed ADT at full build -out; recommend
list ADT on plan sheet C0.0. (Rev. 3a) Addressed. Timmons email, 8/1/2019 9:32 AM: `Per the Kimley-

13. XS-27 — XS-36: VDOT (11/8/18) review comment #5: "The provided typical sections appear to have gutter
in sections that slope away from the curb and CG-2 in sections that slope toward the curb. Please explain."
Code requires curb and gutter (shall be constructed with) in the development areas. Revise design for all
stations with shoulder and ditch sections. Ref. VDOT Subdivision Street Design Guide, Appendix B(1),
Table 1, Geometric Design Standards for Residential and Mixed Use Subdivision Streets, which applies to
Lewis and Clark Road Extension. (Rev. 1) Addressed. Applicant response: `The road has been designed
with superelevation in accordance with TC-5.11, 45 MPH Urban Low -Speed design standards. This causes
some sections of the road to slope towards the center median. Inlets have been provided along the median
where required. The current design allows for the construction of the western two lanes of the future 4
lanes full road section with a center median. Curb and gutter have been provided in all locations where it
will also be necessary for the final 4 lane condition. Curb and gutter has been excluded along some sections
of the road which will need to be modified for the future 4 lane widening. In the future, 4 lane condition
curb and gutter or curb will be provided on both sides of the final road.'

From VDOT Drainage Manual:
9.4.8.7 Maximum Grades
Slopes that incur uniform flow velocities in excess of 10 fps -should be avoided because
of the potential for abi5istion. Slopes in excess of 16% are no�p eferred because of the
need for anchor blocks. When anchor blocks are used, they should be installed at
every other pipe joint, as a minimum. (See Special Design Drawing No. A-73 and MA-
73 for Anchor Details for Concrete Pipe)
