1. Show entire preserved slopes overlay on plans and remove disturbances. Aerial topography will
not warrant removal of preserved slope designations. A field survey provided by a licensed
Professional Surveyor would be required. In addition, while it is possible that a field survey may
prove that some slopes designated as preserved are less than 25 %, it will likely warrant additional
areas to be designated as preserved, as the site must be reevaluated as a whole. The steep slopes
overlay district tries to preserve contiguous areas, so results of any new evaluation will need to
avoid breaking slope areas into fragments. [30.7.4(b)(h)]
(Rev. 1) Comment not addressed. As stated in the 19 October 2015 VSMP review letter, "Per
Section 30.7.4(b)(h) of the County Code; new topographic information should be based on more
accurate or better technical data demonstrating that slopes are less than twenty -five percent, to the
satisfaction of the County Engineer (emphasis added). The County Engineer requires either a field
survey, provided by a licensed Professional Survey, or convincing certified documentation that the
new aerial topographic source is more accurate than the existing steep slopes overlay district
topography." This documentation has not been provided for the County Engineer's review..
2. "All streets within a development shall be extended and constructed to the abutting property lines
to provide vehicular and pedestrian interconnections to future development on adjoining lands,
terminating within the development with a temporary turnaround." [32.7.2.2(e) & 14.409(B)]
Please provide a turnaround at the Free State Drive stub -out that meets the requirements of the
Albemarle County Design Standards Manual.
(Rev. 1) Comment addressed. Given the potential for the street to be extended onto the adjacent
parcel, the County Engineer has deemed the currently proposed t -type turnaround as acceptable.
3. Turnaround grades should be a maximum of 6 %, please adjust. Also, the gutter should not be
included in your roundabout dimensions. Ensure that the edge of pavement radius meets the
Albemarle County Design Standards Manual.
(Rev. 1) Comment not addressed. The 6% you're showing on the profile represents the
centerline of the road. However this does not represent the cul -de -sac, as it is offset. The cul -de-
sac is greater than 6 %, please adjust.
4. Show stationing at a 50' minimum on all proposed streets, on plan and profile.
(Rev. 1) Comment addressed.
5. You are showing a stacking block retaining wall between lots 10 & 11 with a maximum height of
8 feet. Provide sealed retaining wall plans for this wall.

(Rev. 1) Comment not addressed. The provided generic detail is inadequate for an 8' wall and
that is so close to the adjacent property. Calculations have not been provided and there is no
indication as to where /which wall this represents. Please see attached retaining wall plan checklist
for minimum required documentation.
6. The cross -walk on Free State Drive that is located in the curve, just beyond the crest, should be
relocated.
(Rev. 1) Comment not addressed. A sight distance exhibit, noted in your response letter,
showing that this crosswalk is in clear view is not found. This is not an ideal location for a
crosswalk. Please relocate.
7. A guardrail is needed on the outside of the curve on Free State Drive, please provide.
(Rev. 1) Comment retracted.
8. It is difficult to make out the asphalt layers in your road cross - sections, and it's not clear to what
each leader is pointing. To avoid confusion, please list the asphalt layers and their corresponding
thicknesses for each road section.
(Rev. 1) Comment addressed.
9. Provide the Albemarle County General Construction Notes for Streets.
(Rev. 1) Comment addressed.
10. Provide traffic generation summary and pavement design calculations.
(Rev. 1) Comment addressed.
11. Call out all proposed slopes on Landscape Plan that are steeper than 2:1 and specify low -
maintenance ground cover (not grass).
(Rev. 1) Comment addressed.
12. Drainage computations and maps were not found with this submission; therefore, a review of the
drainage plan could not be performed.
(Rev. 1) Comment not full addressed. Please reflect the requested changes in the VSMP and
supplemental email (11 /4/2015) in your drainage calculation packet.
Comments from VDOT, Planning, ACSA, and Fire & Rescue will be forwarded as they are received.
