Addressed.
30. [Z.O. 32.6.2(a), Sec. 32.5.2(a)] Revise the Site Data information on Sheet 1 (Cover
Sheet) as follows:
A. Revise the "Critical Slopes" label to "Steep Slopes" (Critical Slopes are only
located in the Rural Areas; Steep Slopes are only located in the Development
Areas);
B. In the corresponding description for "Critical Slopes," change all instances of
`"critical slopes" to read "Steep Slopes" or "Preserved Steep Slopes" (as
applicable); and
C. Revise (update) the description of the document approved by the Engineering
Division (titled "The Vistas at South Pantops Critical Slope Exhibit") to include
additional reference to the most recent approval date (3/22/2019).
RESPONSE: All notes have been revised.
31. [Z.O. 32.6.2(a), Sec. 32.5.2(a), 32.6.2(g)] As of 511Ui101y" it is the understanding of
CDD-Planning staff that some the proposed "Open Space" designations on the Final
Site Plan will need to be revised as described below; this will require revisions to
labels, notes, and other information on Sheet 3 (Site Layout Plan), and Sheet 4
(Layout Plan — Ground Level Parking), as well as revisions to the corresponding Draft
Special Lot Plat SUB201800176.
a. After recent coordination with County staff within and outside of the Community
Development Department, the "upper' proposed Open Space (identified as an
approximately 2.99-acre area labeled as "County Park' on corresponding Draft
Special Lot Plat) should no longer be reserved for future dedication to the County
due to the overlapping (proposed) SWM Forest/Open Space Easement in this
same area. Instead, this "upper' proposed Open Space should continue to be
designated as Open Space on the Final Site Plan, but with a new designation as
a proposed public use and access easement, and this public easement will need
to be shown on the corresponding Special Lot Plat and also the corresponding
Easement Plat submission (with corresponding legal documents also being
required).
b. The "lower" proposed Open Space (identified as an approximately 3.91-acre area
labeled as "Greenway Reservation" on corresponding Draft Special Lot Plat)
should also continue to be designated as Open Space on the Final Site Plan, and
must remain designated as being reserved for future dedication to the County (as
has been previously established by, and as is required by, the terms of recorded
plat in Deed Book 2913, pages 156-162, recorded 2/1/2005).
c. (*) Note: CDD-Planning staff will continue to coordinate closely with the
applicants and consultants, as well as all other regulatory stakeholders, to
successfully identify a solution to the issues associated with the proposed Open
Space (shown on the Final Site Plan) in relation to the proposed SWM Forest /
Open Space Easement (shown on the WPO Plan).
RESPONSE: In phone conversation and follow-up email from Tim Padalino, dated 20 May
2019: "The Open Space areas shown on the final site plan and special lot plat can and
should remain designated as being `reserved for future dedication to the County for
public use.' The Open Space areas should not be designated as a public use and/or
public access easement. These updates override I supersede review comment #31 from
the 5110 review comment letter. In coordination with multiple County Divisions and
Departments, it has recently been confirmed that the reservation for future dedication is
acceptable. I apologize for any uncertainty and delay that may have resulted from the
varying guidance provided by County staff."
32. [Z.O. Sec. 32.7.9.4.(d)] Please add the required "verification of compliance" note to
the Landscape Plan. Please include the following standard plant health note: "All site
plantings of trees and shrubs shall be allowed to reach, and be maintained at, mature
height; the toping of trees is prohibited. Shrubs and trees shall be pruned minimally
and only to support the overall health of the plant."
RESPONSE: The note has been on sheet 9 "Landscaping Plan notes & details"
under "General Notes & Minimum Standards". Verification of compliance has been
added. Additionally, the notes have been added to plan view on sheet 8 to provide
additional clarity.
33. [Advisory]: It is the understanding of CDD-Planning staff that any maintenance
within VDOT ROW is conducted solely by VDOT; please coordinate with VDOT staff
and Albemarle County Parks and Recreation staff to determine the necessity of
revising the following notes on Sheet 3 (Site Layout Plan):
a. "Proposed pedestrian crosswalk to be maintained by developer" and
b. "Location of proposed pedestrian crosswalk and connection point to trail to be
determined and maintained by Parks and Rec Dept."
c. Note: Permissibility and location of proposed crosswalks are subject to VDOT
approval; CDD- Planning staff strongly support the design and implementation of
pedestrian crosswalks (with appropriate signage, as may be applicable) across
South Pantops Drive, which would also support and advance relevant
Comprehensive Plan goals and recommendations.
RESPONSE: The northern most crosswalk has been removed per VDOT request.
The crosswalk at the entrance has been resolved with VOOT. (see VDOT comments
below)
34. [Advisory]: The following remaining approvais are requirea prior to approval of
final site plan SDP-2018- 00085:
a. [Z.O. Section 32.7.4.1.a]: Water Protection Ordinance Plan (and corresponding
legal documents) / WPO-2018-00095
b. [Z.O. Sections 32.7.4.2 and 32.7.5.3]: Easement Plat (and corresponding legal
documents)
c. [Z.O. Section 32.7.1.1]: Special Lot Plat (and corresponding legal document) /
SUB-2018- 00176; and
d. Tentative approvals (review status of "No Objection") from all applicable SRC

67. [NEW] (Rev.1) Sheet 3 and 4:
a. Provide correct sheet callout for trash compactor. Correct the CG-12 callout
along South Pantops (should be CG-6) and page reference label (should be
sheet 18) for guardrail terminal detail.
b. Label retaining walls over 30-inces and not integral to the building wall design
(RW#1, RW#2, etc.). provide max height, TW/BW spot elevations for retaining
wall at SW parking lot comer near building #3. Guardrail warranted in front of
retaining wall for last two parking spaces.
c. Specify UD-3 for proposed sidewalk along South Pantops. UD-3 to outlet to EW-
12 or proposed flume drain str. Show UD-3 in the sidewalk details.
RESPONSE: Dumpster, curb, and guardrail labels have been corrected. Guardrail has
been added to SW wall. TW1BW spots have been added to SW parking lot wall. UD-3 label
has been added to sheets. UD-3 detail added to sheet 18.
68. [NEW] (Rev.1) Sheet 6: Correct grading near entrance where the ditch (to be
removed/demoed) and curb/sidewalk meet. Sidewalks shall be generally level with
minimal surface warping; cross -slope shall not exceed 2%.
RESPONSE: Grading has been corrected; cross -slope shall not exceed 2%.
69. [NEW] (Rev.1) Sheet 13:
a. Velocity in pipes (2-1) & (1-Out) & outlet is considered excessive. Reduce
pipe velocity to 20fps or less, and outlet velocity to 10fps or less. A possible
solution would be to install additional `step-down' manhole/s.
b. Show size of drainage area going to flume off of s.pantops. I believe the total
drainage area going to is more than 0.02ac. Is EC-3 adequate, if not provide
alternative?
RESPONSE: Comment #69(a) withdrawn at meeting on 3 May 2019 at County Office with
David .lames, John Anderson, and Frank Pohl. Please see sheet 12 for drainage area
going to flume. The typo for the area has been corrected. EC-3 is adequate up to
velocities of 10ftfs per VDOT. We have a velocity of 5 ft/s for the 25-yr storm.

a. "Retainin walls greater than 3 feet in height require a separate building permit. Walls
exceeding 4 feet in height require a stamped engineered design also.
b. ALL water lines, sewer lines, and fire ines from the main to the structure must have a visual
inspection performed by the building department.
c. ALL roof drains shall discharge in a manner not to cause a public nuisance and not over
sidewalks.

Virginia Department of Transportation (Adam Moore
1. The 12' offset and taper, turning right out of the entrance, is a requirement for entrances
along highways with shoulders. However, this plan proposes curb and gutter. Please see
Figure 4-10 on page F-109 of Appendix F
Response: The entrance has been corrected.
2. Sidewalks must be 8' in width if adjacent to curb without a buffer strip.
Response: Per appendix A(1)-71: "No" on -street parking situations 5 foot sidewalk with
no buffer strip requires the submission of a design waiver. Waiver request is included
with this submission.
3. Please provide more detail concerning the proposed flume; what warrants this and how
does this alleviate the concern? It appears that a DI is warranted here instead, which must
lead to an established outfall.
Response: The existing conditions of the site has no curb and gutter and the water is
allowed to flow freely over the slopes to the creek below. Albemarle county planning
department has requested that sidewalk be installed along the frontage of this parcel to
allow for pedestrian interconnectivity in Pantops. Along with the submission of the Final
Site Plan, I have included an exhibit which shows a profile of a potential manhole and
pipe that would outfall to the existing drainage channel. The drainage area contributing
to the flume is 0.26 acres. A flume is proposed in lieu of an inlet and pipe due to the
proximity of the existing waterline, 18" Asbestos sanitary pipe, and critical steep slopes
(please see the profile provided). It is the desire of the County Engineering Department to
avoid disturbance to the Steep Slopes. The installation of a curb cut and paved flume is
the least invasive option. I have also included photos of similar design flumes in the
area.
4. The proposed crosswalk markings on S. Pantops Drive do not appear to be warranted.
Please see IIM-TE-384. Additionally, please provide justification for any proposed midblock
pedestrian crossings of S. Pantops Drive.
Response: Resolved via phone call with Justin Deel on 5/2812019. The crosswalk at the
north end of the parcel has been removed. Crosswalk at entrance to remain.
5. CG-12s are needed at the site entrance, angled perpendicular to the entrance
Response: CG-12 have been added at the entrance.
6. The entire adjacent through lane throughout the width of the entrance must be included in
the area of mill & overlay on S. Pantops Road. Include callout on plans indicated this is the
area to be milled & overlayed in accordance with the WP-2 detail.
Response: The label has been corrected.
We thank you for taking the time to review these plans and trust the above adequately
addresses your comments. However, please let me know if you have any questions or require
