1. C2.0
a. Please provide deed bk.-pg. ref. for existing public drainage easement for storm conveyance
leaving the Guadalajara property to the south, then transiting hotel development parcel. (FSP)
Addressed.
b. Show and label managed steep slopes. (FSP) Addressed.
c. Revise label reading `Use: vacant, TNT 78-1 V since it is a commercial car sales parking lot with
non -vacant use (blue -circle area, image, below). (FSP) Partially addressed. Applicant response
(letter d. 21-Jun 2022): `The use for TAP parcel 78-11 has been updated to "commercial car sales
parking." ' As follow-up: Please ensure parcel ownership data for 78-11B1 and 78-9C displays.
[Image removed with ESP comments.]
d. Please consider and provide collection/conveyance (as needed) of storm runoff that may transit
existing drainage ditch that crosses the hotel site, a ditch beginning near the car sales parking lot
(blue aFT-aw, -ielaw): [Image removed with ESP review comments.] (FSP) Addressed. Applicant:
`Given the updated survey, a drainage ditch does not exist through the proposed site. See Sheet
C2.0. Any off -site storm runoff that may flow from the car sales parking lot towards the site will
be captured by curb and routed to an existing storm inlet east of the proposed site (detailed
stormwater management plans are included with the WPO plans).' Note: WP0202200027,
submitted 7/7/22, review pending.
e. Show /label existing sidewalk adjacent to Town and Country Lane. Determine and label ex.
sidewalk width. (FSP) Addressed.
f. Plan appears to propose elimination of this sidewalk; preserve walk as a required element of
public streets per subdivision street design guide, VDOT Road Design Manual, Appx. B(1).
n...',....& 2 ...mite :...agog [Image deleted with ESP review comments] (FSP) Addressed.
Applicant: `The sidewalk along Town and Country Lane and Olympia Drive will be demolished

a. Please revise label reading `retaining wall with fall protection barrier on top for vehicles and
pedestrians' to `retaining wall with guardrail' since guardrail is appropriate for vehicles. VDOT
GR-2 standard is available to include on plans. (FSP) Addressed.
b. Provide wheel stops for parking spaces fronting retaining wall. (FSP) Withdrawn. Applicant:
`Referencing the 16' deep parking spaces facing the retaining wall north of the project site, curb is
being proposed as a wheel stop so that the 2' planting strip can be utilized for the required vehicle
overhang. The 16' deep parking spaces are necessary to keep a 26' drive aisle along that section
of the site for fire access.'
c. Label narrowest width of curvilinear parking spaces in sections that do not label width at
narrowest dimension. (FSP) Addressed.
d. Revise parking space -sidewalk design; select from allowable parking -sidewalk configurations at p.
17, ACDSM, which requires, for example, wheel stops for 18' L spaces w/ 5' w sidewalks
(haps://www.albemarle.orgjEome/ShowDocument?id=270 ). (FSP) Addressed.
e. Identify curb type/s. (FSP) Addressed.
f Label all sidewalk widths. (FSP) Addressed.
g. Provide HC-parking space signs. (FSP) Addressed.
h. East entrance to hotel may limit fire rescue (apparatus) access to site.

ii. If ACFR requests site access to include unrestricted access around the hotel, ensure
retaining wall design accommodates ACFR vehicle weight (65,000 - 80,0001b.), or
weight of vehicle class likely to respond from ACFR Station 16, Pantops. (FSP)
Addressed. Applicant: `Noted, retaining wall will be designed to accommodate the
ACFR vehicle weight.'
iii. If ACFR apparatus requires access around hotel, ensure retaining wall guardrail
accommodates overhang portion of ACFR vehicle, from front axle to front fender. (FSP)
Addressed. Applicant: `An Auto -turn analysis has been performed confirming the
accommodation of the ACFR vehicle. An exhibit of this analysis can be provided upon
request.' Asfollow-u : Please provide exhibit.
iv. (Please do not assume ACFR vehicles are permitted to stage vehicles or response or
presence within public RW of Town and Country Lane, or Olympia Drive.) (FSP)
Addressed. Applicant: `Noted, this is not being assumed. The drive aisle is 26' on the
north and south sides of the hotel to allow for vehicle staging.'
i. Provide GR-2 with labels for retaining wall located along linear and curvilinear parking along N
edge of hotel parking lot. (FSP) Addressed. Applicant: `Guardrail has been called out on top of
the proposed retaining wall along Town and Country Lane and as well Olympia Drive. The
guardrail and retaining wall integration will be further designed and detailed by a structural
engineer for the second submission of the final site plan. A note of this has been provided with
the detail on Sheet C 1. L'
j. Increase 3' sidewalk width along Olympia Drive to meet VDOT minimum sidewalk width, 5'.
[See VDOT Road Design Manual, Appx. B(1), Sec. 41I A(2) -

a. Convert parking space with SWM facility manway access to a parking island so that manway
access is not obstructed by a parked vehicle. (FSP) NA. Applicant: `The UG detention system has
been removed as the downstream pond [sic, biofilter] was designed [for] this site. This has been
coordinated with county staff and calculations will be provided with the WPO plans.'
b. Provide drainage profiles (storm pipes, UG SWM detention facility). (FSP) Partially addressed.
As follow-up:
i. Please provide profile label to require %:" steel plate in the floor of MH Str. 102. Ref.
VDOT Drainage Manual, p. 9-37, Sec. 9.4.8.7., Maximum grades.
ii. Comment 3.b.i. also applies to any other step-down MH Str. where difference between
INV IN and INV OUT > 4-11.
iii. Please provide SL-1 profile label (safety slab) for MH Str. 102, and any other MH Str.
where the difference between top of structure and INV OUT > 12-ft.
iv. Revise depth /slope of pipe 107 so that 20' easement width for this pipe (C4.1) may be
minimized to extent possible. 20' easement width jeopardizes hotel foundation (strip
footer) and likely conflicts with retaining wall. Amending depth /slope of pipe 107
requires adjustment to pipe 300, as well, but it appears possible to raise both pipes.
(Please see ACDSM easement width diagram, below, item 3.e.)
c. Show /label a public drainage easement extending from UG detention system (SWM easement)
that is centered on the facility outfall pipe, OF, to the property boundary. (FSP) NA. Applicant:
`As mentioned above, the UG detention system has been removed with this submission. All
proposed drainage easements for the other storm structures/sewer have been provided on sheet
C4. L'
d. Provide detail for relieving arch or pipe sleeve where UG SWM facility outfall pipe, OF, is
proposed to pass beneath retaining wall near Olympia Drive. Consider and discuss alternatives, or
if no alternative SWM facility outfall location exists, establish this via notes, labels, etc. (FSP)
Persists. Applicant: `The retaining wall design will not be submitted for the first submission of the
final site plan. The retaining wall will be designed by a structural engineer and detailed for the
second submission of the final site plan. We are actively working with geotechnical and structural
engineers to design a retaining wall that integrates a guardrail and provides relief for the proposed
outfall pipe. As mentioned above, the UG detention system has been removed with this
submission.'
e. It is not possible without SWM detention profile to evaluate proposed SWM facility easement
with precision. As design advances, please consult ACDSM, P. 15, Easement diagram to
determine required SWM facility easement width. (FSP) Withdrawn. Applicant: `As mentioned
above, the UG detention system has been removed, and has been replaced with storm pipe for the
proposed storm system. All proposed easements have been provided on sheet C4. L'

drainage computations will be included with the WPO resubmission.' Note: Ref.
WPO202200027, sheet C6.2.
g. Proposed retaining walls are shown within existing public drainage easement, existing storm pipes
are shown crossing beneath or intersecting proposed retaining wall. Provide final site plan that
indicates existing storm drain pipes are relocated to avoid any construction or future maintenance
conflict with retaining walls. No permanent improvements of type proposed are allowed within
public drainage easement. (FSP) Addressed. Applicant: `The existing storm pipes have been
relocated to avoid any future conflicts with maintenance or construction with the proposed
retaining wall. The existing public drainage easement has been abandoned. A proposed public
drainage easement is provided on sheet C4.1, with no permanent improvements proposed within.
See note on sheet C4.1.'
h. Establish new public drainage easement centered on relocated existing storm drain lines. (FSP)

approval. (FSP) Persists. Applicant: `New platted public drainage easements will be provided
with future submittal.'
j. Note: WPO plan approval is a prerequisite to ESP approval. (FSP) Acknowledged.
WPO202200027 received 7/7/22, review pending.
k. Furnish relevant design data with WPO, including weir plate, manway, weir orifice design, debris
cage, typ. details, plan/profile, etc., as needed. (FSP) May Persist with WPO plan. Applicant:
`All relevant stormwater information has been provided with WPO submission.'
1. Avoid nuisance ponding at all locations across parking lots /across site act Main entrance to
hotel appears somewhat susceptible to nuisance pending /ice in winter. (FSP) Addressed.
Applicant: `With the grading and site constraints, the main entrance to the hotel is lower than the
entrance grading. Trench drains have been placed in front of the main entrance of the hotel, and
the pavement is crested near the entrance to ensure positive drainage away from the entrance.
Most of this area is covered with an overhang, reducing the actual runoff to this area. Inlet sizing
calculations will be provided with the WPO plans.' Note: Calcs shown on WPO plan, sheet C6.2.
m. Ensure parking lot grade near S entrance to hotel is < 5%' -5.25% impermissible. [ 18-4.12.15.c.]
(FSP) Addressed. Applicant: `With the grading constraints of the site and access requirements,
we currently have a maximum grade of 6% in the parking aisles and spaces. This is the maximum
one -point slope —the slopes parallel and perpendicular to the stalls are less than 5% in each
direction.'
n. Ensure slope, S entrance to hotel is <10% in every direction. [ 18-4.12.17.a.] (FSP) Addressed.
o. Revise grade, S entrance to hotel such that side -slope is traversable for tall (high -clearance) trucks,
side -slope is severe at this location posing risk of tipping /loss of control in wet or icy conditions.
(FSP) Addressed. Applicant: `The grading in the S entrance to the hotel has been revised to
reduce the severity of the cross slope to approx. 3%.'
p. Provide /label CG-6 wherever runoff concentrates against curbing, for example: loop around west
end of hotel. (FSP) Addressed.
