RE: SDP 201300047 Hollymead Town Center Block C4— Final Site Plan
Dear Sarah,
Enclosed please find eight (8) sets of Final Site Plan for the referenced project. Please note that we
have revised the site plan to address the following review comments:
PLANNING COMMENTS
9. [4.12.6] Clarify the Total Provided Parking for Townhouses table. It seems to conflict with the
Parking Tabulations and provides more than 20% over the maximum parking requirements, which is
not permitted in the ordinance.
RESPONSE: As discussed with Albemarle County Planning on 1-30-14, we have added a note
to the parking tabulations indicating that 6 of the 2-bay garage parking spaces are not to be
counted towards the parking provided for the purposes of maximum parking calculations. As
presented on Sheet 2, the site complies with the maximum parking requirements.
10. [4.4] Sheet 5 shows sight distance going though the back of unit 6, which must be corrected.
RESPONSE: As discussed there is an uncovered stoop at the back of unit 6, so the sight
distance is not an issue.
ENGINEERING COMMENTS
As discussed with Albemarle County Engineering, we have made the final changes to the site
plan:
1. Extended the grassed median between lots 2/3, 4/5 and 14/15 to the back of the ribbon
curb.
2. Provided 1' wall for the 3'-wide concrete islands adjacent to buildings that have a 1-foot
elevation drop.
3. Provided a 1' wall detail.

RE: SDP 201300047 Hollymead Town Center Block C4—Final Site Plan
Dear Sarah,
Enclosed please find four(4) sets of Final Site Plan for the referenced project. Please note that we have
revised the site plan to address the following review comments:
PLANNING COMMENTS
My Comment 1 on the prior SDP memo should be the site plan should be approved prior to the subdivision
RESPONSE: Acknowledged. Our plan is to achieve site plan approval with this submission.
ARB COMMENTS
The ARB approved the site plan on November 26, 2013. The ARB approval letter is attached to this
submission.
ENGINEERING COMMENTS
3. Please provide typical sections and profiles for proposed street.
I RCN ision I) Comment addressed.
[Revision 2] The profiles are now shown.The road with ribbon curb and 2% cross slopes was
discussed as approvable on Sept 12,2013.However,the vertical alignment does not work well on
site.I recommend the following:
a) Reduce to 3 or 4 vertical curves for better transition(This#excludes entrance curves).
b) Show the grade break from road to all driveways to not exceed 10%.Driveway should
still resemble grading on CG9D (section A-A).Label grades for each driveway.
c) Revise vertical curve#10 to have a K value of 5,at a minimum.
Response to 3a): As discussed on the telephone,the vertical curves as designed are acceptable.
Response to 3b): The driveway grades have been labeled. None of the driveway grades are steeper
than 10%.
Response to 3c): For clarity,we have removed the K value for the vertical curves at the intersections.
This would include vertical curves#1 and #10 for Firewood Circle and#1 and#5 for Kindling Lane. For
these vertical curves,the K-value is not appropriate since the 10' parabolic curve is a VDOT standard
requirement, regardless of the resulting K value. Please note that these curves are at a stop condition,
so none of the K value design criteria are relevant. See below for VDOT standard CG-11 detail.

4. Per 14-410 H, please show curb and gutter for proposed street. Please show standard entrance gutter,
CG-9D, and improve runoff catchement by placing additional DI's. Also,a DI shall be placed before
intersections. Please provide a DI near lot 7.
(ReN ision 1] Comment not addressed. Pros ide curls and gutter for road NS ith the standard ('(;-91)
for each (Iris essas entrance. The painted N1 hite line is not recommended.
[Revision 2] A concrete ribbon was discussed as approvable.Please label on Sheet SPSA where
CG-2,CG-6, rolltop curb,ribbon curb should be constructed.Also,extend median to curb
between each lot from 13 to 16 and between lot 20 and 21.
Response to 4: Labels have been added to Sheet 5A to indicate where CG-2, CG-6, rolltop curb and
ribbon curb is to be constructed. As discussed,after having provided more detailed grading of the
driveways,the transition from lot to lot will be smooth and therefore extension of the median should not
be required as this will only serve to provide a more difficult maneuverability from the driveways to the
travel aisle.
10. Please ensure all items in proffer 2 are addressed prior to approval of site plan. Per proffer 3,"All
road improvements listed in proffer 2 above shall be substantially completed prior to the issuance of
the first Certificate of Occupancy in Area C..."
(Res ision 1( Comment not addressed.
[Revision 2] Comment acknowledged by developer.
Response to 10: The developer is currently working on the road acceptance.
16. It appears there is a concrete median between each driveway. Will this be concrete, a planting strip or
gravel?Please clarify. Also, note a minimum of 3' should be provided for a concrete median.
[Revision 2] Comment addressed,but the grading for median will not work well in areas where
there is a 1' drop.I recommend providing a 1'wall to make up the elevation change between lots
with a 1' drop or provide an alternative solution.
17. Clarify what will be in the 6' median between each driveway. Grass or gravel?

with a 1' drop or provide an alternative solution.
Responses to 16 and 17: We have made up the 1'transition in between units with a 1' drop via either the
3' concrete curb or the 6' grassed median.
19. The pipe between structures 62 and 61 will be undersized when the drainage system for this site
is connected.Please refer to WPO201300058 comments.
Responses to 19: We have added HGL computations and a 10-yr HGL to the profiles on Sheet 7 to
indicate that the existing pipe system is adequate to convey the design flow within the system.
We trust the above adequately addresses your comments. Please let me know if you have any questions or
require additional information.
