For Final Site Plan approval:
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, TMP 78-11' 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 TMP parcel 78-11 has been updated to "commercial car sales
parking." ' As follow-up: Please ensure parcel ownership data for 78-11B 1 and 78-9C displays.
[Image removed with ESP comments.] (Rev. 1) Addressed.
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 www, below): [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
storrnwater 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).

2. C4.0
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 (FSP) Withdrawn.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.

accommodation of the ACFR vehicle. An exhibit of this analysis can be provided upon
request.' Asfollow-u : Please provide exhibit. (Rev. 1) Persists.
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'.

n. Note: All walls >3-ft. ht. not integral to building design will require building permit from building
inspections, CDD. (FSP) May persist. Applicant: `Acknowledged.' (Rev. 1) Persists. Applicant
response (12/20/22 letter): `Acknowledged.'
3. C5.0
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.'

where the difference between top of structure and INV OUT > 12-ft. (Rev.1)
Addressed. [ MH Str. 102, no other str. has diff. > 12-11. between rim /INV OUT.]
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.) (Rev. 1) Addressed.
Applicant: `Context has been provided on the storm profiles (see sheet C7.0) of the
building footer and its load plane. The building footer's load plane projects under the
proposed storm pipe (107). The horizontal distance between storm pipe 107 and the
building footer is 10'. The horizontal distance between storm pipe 107 and the retaining
wall is 14.5'.
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.' (Rev. 1) Addressed. Applicant: `Details for the storm sewer pipe passing beneath
the retaining wall have been provided in the retaining wall design.' [Circeo RW design, 12/12/22]
e. It is not possible without SWM detention profile to evaluate proposed SWM facility easement
with precision. As design advances, please consult ACDSM, i, 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' [ ACDSM
image /easement diagram removed with Rev. 1 comments.]
f Provide VDOT LD-204 inlet computations. Provide LD-229 storm drain design computations.
(FSP) Addressed. Applicant: `All VDOT LD-204 inlet computations and VDOT LD-229 storm
drainage computations will be included with the WPO resubmission.' Note: Ref.
WP0202200027, sheet C6.2.

Addressed. WPO202200027 review comments sent 1/6/23.
I. Avoid nuisance ponding at all locations across parking lots /across site access. Main entrance to
hotel appears somewhat susceptible to nuisance ponding /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.

wall weep discharge and is being proposed to tie into storm pipe 101. See sheet C5.0. This specific
drainage system and tie-in will be fruther designed and detailed with the retaining wall and
submitted for the second submission of the final site plan. A note of this has been added to sheets
C4.0 and C5.0.'
v. Acquire /record off -site temporary construction easement to perform grading on TMP 07800-00-
00-009CO3 or provide copy of written agreement to perform grading across or at edge of this
parcel. Proposed site contours are infeasible without easement /Agreement from this TMP owner.
(FSP) Persists. Applicant: `Approaches for this are being coordinated and will be further
discussed with the next submission.' (Rev. 1) Addressed. Applicant: `Grading has been revised to
illustrate how grades can comfortably tie in without crossing the property line and as such off -site
easements and/or agreements are not required. See sheet C5.1. Further strict language has been
added to the plans to ensure the contractor will not cross the property line with installation of
improvements.'
4. Submit a WPO plan for hotel development at earliest convenience. (FSP) Addressed. WPO202200027
