MEMO,
1. Provide 1" =2,000 (or less) scale vicinity map. (FSP) Addressed.
2. Include SDP201800078 in revised initial site plan title. (FSP) Addressed. As follow-up: With
assignment of FSP file identifier, please revise next submittal to ref. SDP2019-00013. (Rev. 1)
Addressed.
3. Engineering recommends include ZMA201300002 proffer on title sheet. (FSP) Addressed.
4. Ref. WP0201800088 (Pantops Corner VSMP Plan) as well as WP0201400028, Mass Grading
and Erosion & Sediment Control Plan for Pantops Coiner, approved 6/11/14, with estimated area to
be disturbed =7.01 Ac. (FSP) Addressed.
5. Note: Site under development does not have an existing stormwater management plan. A Mass
Grading and ESC Plan was approved, 6/11/14. No development layout is shown with the Mass
Grading and ESC Plan. Grandfathering (9VAC25-870-48) would not apply in this instance, for this
reason. VAR IOE170 (VSMP Program VPDES) permit was issued for mass grading on 9/9/14.
Grading has been performed, and site should be stabilized. If mass grade operations are complete, and
site stabilized, it is time to terminate VAR10E170, and apply for a new VSMP permit for never -
reviewed proposed development on this parcel. Further, VDEQ SWCGP database lists Construction
Activity Operator (VAR 10E170) that does not match Initial Site Plan Owner information. Albemarle
does not accept the position that this development is eligible for grandfathering, but views development
subject to stormwater quality and quantity requirements at 9VAC25-870-65 and 9VAC25-870-66.
(FSP) Review error. Comment withdrawn.
CV- 101 (Existing Conditions)
6. Do not show: (FSP) Item 6 Addressed.
a. Proposed development on TMP 78-58G1, which does not exist.
b. Any proposed development features on TMP 78-5A, unless they exist.
C. Show existing features only. If Applicant arranged with Planning Division to represent
proposed features on CV-101 (Existing conditions), provide whatever elements were
requested as an Exhibit or separate ISP sheet with appropriate title.

7. Do show: (FSP) Item 7 Addressed.
a. Full width of U.S. Rt. 250 where it fronts TMP #78-5A. Show existing travel lanes, turn
lanes, traffic signs, median, etc.
b. Steep slopes (Ref. County GIS Critical Resource layer). Managed steep slopes exist on
this parcel.
C. Proposed RW for private road Pantops Corner Way. (FSP) Addressed. Applicant
response: `The proposed public access easement for the Pantops Corner Way is shown on
Sheet CV-102 and CS- 101. There is no proposed right-of-way for this road.'
8. Add Note stating that all known existing easements are shown, or that none exist on TMP# 78-5A.
(FSP) Addressed.
9. Provide Ownership information for parcel under development, and adjacent parcels: provide
TMP#, owner name, DB/PG. (FSP) Addressed.
CS- 101 (Site and Utilitv Plan
10. Transfer proposed development features from CV- 101 to CS- 101, including:
a. For FSP approval (submit /respond to comments until approved):
i. Retaining wall design, since proposed retaining walls support necessary
infrastructure (engineered plans, not generic manufacturer's details). Consider
county retaining wall plan review checklist. (FSP) Not addressed. See proposed
plan view information, Final Site Plan checklist (Attached). Engineering restates
requests for design to consider retaining wall plan review checklist. Specifically:
1. Provide complete retaining wall design specific to site design and site
geotechnical parameters sealed by a geotechnical PE, for all walls that
support infrastructure, roads, parking lots, drive aisles, or in close proximity
to a property line. Final Site Plan checklist for reviewers states: `Retaining
Wall Plans checklist. Any walls supporting roads or necessary infrastructure
require engineered plans (not generic manufacturer's details) and computations.
,Design Manual, section 8} This will also be required where walls are close to
property lines and there is the danger of affecting neighboring property, either
during construction, with later failures, or with pedestrian or vehicle safety.
These concerns can be alleviated with layout spacing also. In any case,
retaining walls will require building permits at construction.' (Rev. 1)
Addressed.
2. Delete reference labels that appear to transfer design responsibility to
Pantops Corner Development. Engineering requires retaining wall design
checklist items for retaining walls integral to Wawa site development. (Rev.
1) Addressed.
3. Provide private easements for retaining walls (Access /maintenance).
(Rev. 1) Withdrawn. Plan review checklists (site /retaining wall) do not
explicitly reference RW easements. Also, it is late to request retaining wall
easements with Pantops Corner final plat (SUB201900059). Walls will be
built with the Pantops Corner Development, not Wawa.
4. Label all six sets of retaining walls shown on plan sheet CV-102
(including a 2-tier wall, and a 3-tier wall). Label 1 - 6, or A - F. (Rev. 1)
Addressed.
5. Only the 5' segmental block retaining wall is exempt from requirement
to provide detailed, PE -sealed plan /profile design. (Rev. 1) Addressed.

2. Pipe and inlet type, length, diameter, material, slope, etc. (FSP)
Addressed.
3. Calculations (LD-204, LD-229)
a. Velocity /Capacity /Inlet spread and depth. (FSP) Partially
Addressed. As,follow-uR: Provide LD-204 Inlet computations.
(Rev. 1) Partially addressed. As follow-up: 8. V spread at LD-204
Table Str. ID 7 appears excessive since located at site entrance.
Please lengthen throat opening, this structure.
4. Profiles, all elements labeled. (FSP) Addressed. As follow-up: In
profile (CG-103), label Sir. B7 and A13 as BY OTHERS, since not existing.
Also, Engineering recommends increase pipe slope from minimal acceptable
0.5% to 0.55%, for example. Often, designing to a minimum introduces
issues during construction. This is a recommendation, not a requirement.
(Rev. 1) Addressed.
5. Label inlets, pipes, and structures (FSP) Partially Addressed. As
.follow-up: Please revise plan sheet CG-101 to Grading and Drainage Plan.
(Rev. 1) Addressed.
iii. Water and sewer line profiles. (FSP) Addressed. (Note: Water Line N/A)
iv. WPO201800088, Pantops Corner, must be approved (prior to Wawa at
Richmond Road and Stores Point Road FSP Approval). (FSP) Comment persists as
noted, elsewhere. (Rev. 1) Addressed. WPO201800088 (Pantops Corner) was
approved 7/23/19.
V. Include Exhibit for o -site (TMP #78-58G1) SWM facilities required to meet
stormwater quality and quantity requirements. (FSP) Not addressed; nor to be
immediately addressed. Applicant (KI-IA) should coordinate with Pantops Corner
LLC (hotel) design engineer (Shimp Engineering) to obtain at least conceptual
stormwater management design information to address water quality and quantity
requirements. At present, Wawa and Pantops Corner, LC (hotel) sites are owned by
a single entity. That site plan application processes are pursued by distinct entities
with Wawa site plan that includes direct /indirect reference to work to be performed
by others (Pantops Corner LC), but there is a single owner (Pantops Corner, LC) at
this time. The VSMP plan, WPO201800088, which amends WPO201400028, must
be approved and bonded, with Wawa site properly registered with DEQ before
SDP201900013 can be approved. Given current single ownership with sale pending
to separate entity, this site plan should include an Exhibit consistent with
WPO201800088 design at point of VSMP approval that ties SWM compliance
requirements and compliance responsibility to the current owner of TMP #78-5A
(Wawa site). Engineering recommends plan sheet images that capture salient specific
SWM facility design information, titled SWM Exhibit Lor reference P!UN. Subtitled:
Ref. WPO201800088 for approved VSMP plan. (Rev. 1) Addressed. Also, see item
33.b., below.
vi. WPO201800088 must be bonded. (FSP) Comment persists. (Rev. 1)
Comment may persist. Will confirm with Management Analyst if bond posted.
vii. Pantops Corner Way must be (built or) bonded to limits required by Planning
Division, as defined by ZMA201300002 proffer. (FSP /Rev. 1) Comment persists.
Applicant response: `Comment noted.' (Rev. 1) Additional: Planning has no
objection to road plan (comment d. 9/6/19). Engineering will coordinate with
Planning to determine limits of road required to be bonded for FSP approval.
11. Note: Provide Road Plan under separate Application to County at earliest convenience. Ensure
road plan design for Pantops Corner Way considers Road Plan checklist for plan reviewers, and
includes a temporary turnaround meeting VDOT, Fire Rescue, and ACDSM needs, unless fiilly

constructed between U.S. Rt. 250 and R. 20 with Wawa. Attached. (FSP) Addressed.
SLB201900024 is under review. (Rev. 1) Comment persists. Nearly all Road Plan review comments
addressed.
12. Light grayscale indicates Pantops Corner Way is existing. Revise to show Pantops Corner Way is
proposed and is to be constructed with Wawa site plan to limits defined by Planning. Provide
turnaround sufficient to meet multiple agencies temporary turnaround requirements. (FSP) Partially
addressed. Applicant response: `The Pantops Corner Way is shown as proposed on Sheet CV- 101 and
shaded as existing on Sheet CS-101 as it will be existing during the construction of the Wawa parcel.'
Asfollow-tip: Label Pantops Corner Way `to be constructed BY OTHERS' on plan sheet CS- 101. (Rev.
1) Addressed.
13. Loading width is less than 12', if exclude area occupied by bollards. Revise to provide min.
loading space width of 12'. (FSP) Addressed.
14. Delete note stating `Terraced Retaining Wall ...is to be designed and constructed as part of
Pantops Corner Development plans.' The terraced retaining walls are intrinsic to site development.
Include engineered PE -sealed retaining wall design plans with FSP. (FSP) Not addressed. Also, item
10.a.i., above. Comment persists. Applicant response: `Once available the retaining wall plans will be
inserted into this plan set. It should be noted that the wall will be constructed by the current landowner
as part of the Pantops Corner Way plans and not by Wawa. It is a condition in the purchase contract
for this wall to be installed by the seller (current landowner).' Engineering welcomes this explanation.
Please submit detailed PE -sealed design for 5 of 6 retaining wall locations shown on CV-102, if CV-
102 remains part of Wawa FSP. If CV-102 is removed from this FSP (as Engineering recommends),
then provide detailed PE -sealed design for all retaining walls on TMP #78-5A prior to FSP approval.
(Rev. 1) Addressed. Ref. 5/28/19 Circeo Design, sheets 7-8. Also, Applicant response (8/27/19): `As
discussed, the retaining walls that are shown on the plans are all designed as part of the Pantops Corner
Development Plans (SDP2018-00089) and are not proposed with the Wawa parcel development.
Therefore, the call outs for the "retaining walls to be designed and constructed as part of Pantops
Corner Development Plans" will remain on CS-101.' Engineering understands /accepts this position.
15. Provide VDOT GR-4- 2 (guardrail) for parking spaces fronting retaining wall; ensure sufficient
parking space depth, once guardrail is installed. (FSP) Addressed.
16. Proposed SS line appears discontinuous. Revise to show connection with Ex. SS, or extend
proposed SS to a logical endpoint. (FSP) Addressed.
17. If proposed retaining wall fronting Pantops Corner Way coincides with managed steep slopes,
ensure design meets (retaining wall) design standards at 18-30.7.5. (FSP) Comment persists.
Applicant response: `The wall plans will be submitted once available.' (Rev. 1) Addressed. Walls C,
D, fronting Pantops Corner Way appear to meet 18-30.7.5 stds. Ref. 5/28/19 Circeo Design, sheets 7-8.
18. Likewise, storm drain pipe from DI at third southernmost parking space facing Pantops Corner
Way is discontinuous. Clarify connection with downgradient elements of storm system. (FSP)
Addressed.
19. Review proposed bike rack to ensure adequate clearance between typ. bike and proposed sidewalk
(F-2' clearance, recommended). (FSP) Addressed.
20. Show proposed easements, including:
a. Drainage (FSP) Partially addressed. As follow-up: Show drainage easements on CG-
101, since CG-101 is a Drainage and Grading plan. CS-100, titled boundary plan, shows
drainage easements, and resembles a plat. Easements need to be shown with pipe /inlet
structures (and SWM facility) if they are to be evaluated. (Rev. 1) Addressed.
i. Ref. ACDSM, pg. 15
b. Sidewalk (FSP) Withdrawn. Sidewalks appear to be within public access easement.
C. ACSA (FSP) Partially Addressed. CS-100 resembles a plat. Show ACSA easements
on CS-101. Same rationale as above: Engineering cannot evaluate easements against invisible
structures. (Rev. 1) Addressed.

37. CV-102: It is unorthodox to include site information for separate parcel with separate site plan
application under review with Albemarle County (SDP201800089). This separate site plan may be
referenced, but detailed information shown with separate final site plan should not be included with
SDP201900013 Final Site Plan (Wawa), as Wawa FSP approval would then in effect approve
SDP201800089 site plan elements. Engineering defers to Planning. (Rev. 1) Comment persists.
Applicant response: `It is understood that the final site plans will not be approved until SDP2018-
00089 plans [Pantops Corner Final Site plan] have been approved.'
38. Note /Reminder: All roadway (Pantops Corner Way /U.S. Rt. 250 /SR 20) elements shown with
FSP201900013 must be consistent with Road Plan design at point Road Plan is approved
(SUB201900024). In other words, Road Plan approval is required prior to FSP approval. (Rev. 1)
Comment persists. Applicant response: `It is understood that the final site plans will not be approved
until Road plans FSP2019-00013 [SUB2019-00024] have been approved.
39. CS- 101 /Site Legend: There is no concrete sidewalk detail on CS-501. Please provide concrete
sidewalk detail or revise title of Mountable curb/island and stamped concrete detail (CS-502), if this
detail may serve two purposes (stamped /plain). (Rev. 1) Addressed.
CS-101
40. Label sidewalk along U.S. Rt. 250 `by others.' (Rev. 1) Addressed.
41. Label sidewalk along Pantops Corner Way `by others.' (Rev. 1) Addressed.
42. Provide bumper blocks for all 18' L parking spaces adjacent to GR-2. (Rev. 1) Withdrawn.
Applicant response: `Wheel stops are not proposed adjacent to the retaining wall and GR-2 as Wawa
does not allow them on their sites due to safety/tripping hazards.' Although withdrawn, Engineering
recommends wheel stops as an additional safety measure for parking spaces adjacent to GR-2. There is
slight likelihood pedestrians exiting vehicles will walk in direction of either GR-2 or retaining walls.
43. Provide /show detectable surface at ramp on west side of stamped asphalt crosswalk. (Rev. 1)
Addressed.
