Dear John,
Thank you for your review of the VSMP request for Byers Fill. This letter contains responses to County

1. Application does not amend WP0201800031, but proposes off -site permanent fill at a private
residence.
Acknowledged.
2. Fill requires a SWPPP, and an ESC Plan. List owners of TMP# 04700-00-00-00 1 CO, not HTC
Hotel.
Acknowledged. SWPPP now is provided with this submission, and the owner of TMP
#04700-00-00-001C0 is now listed.
3. Ref county GIS.
County GIS are referenced on the cover sheet Cl under Source of Boundary and
Topography.
4. Ref. owners of 2856 Laurel Cove Road (TMP# 04700-00-00-001C0), Samuel F. Byers Jr. and
Joann Byers
The owner is referenced on the cover sheet C1 under "Owner."
5. Reference fill; delete stockpile from plan title.
Acknowledged, the word "Stockpile" has been deleted and replaced with the word "Fill."
6. Eliminate reference to HTC hotel in plan title.
Acknowledged, the reference to the HTC Hotel has been eliminated.
7. Revise SWPPP Registration Statement: HTC Hotel LLC is not in this instance Operator
/Permittee.

402.
Acknowledged.
11. Pollution Prevention Plan for HTC Hotel Stockpile is deficient, is a 1-pg. exhibit of insufficient
detail.
Acknowledged, the Pollution Prevention Plan has been updated.
With re -submittal (ESC Plan /SWPPP), please provide /submit (other):
a. $150 application fee /Area of disturbance < 1.0 Ac. (17-207)
Acknowledged.
b. Vicinity map.
Acknowledged, the vicinity map is provided on Sheet Cl at scale l :1000
c. Adequate ESC Plan (permanent fill)
Acknowledged.
d. Narrative —project description, source of fill, associated WPO plan #
Acknowledged, the narrative has been updated.
e. Design (grass -stabilized /other) permanent channels — see below: blue arrows (drainage
created by tying proposed to existing grade)
Acknowledged, a conveyance channel has been designed on the east side of the limits
of disturbance, while the west side of the limits of disturbance has been maintained
by the sheet -flow.
f. Permanent channel calculations (2-yr velocity; 10-yr capacity)
Acknowledged, the calculations of the conveyance channel are provided. Please see
attached SWM packet.
g. Ensure circle -data images are readable
Acknowledged, the circle data has been revised to ensure readability.
h. Sediment trap design data
Acknowledged, sediment trap data are provided with this submission.
i. Phase II ESC Plan, final condition, trap removed
Acknowledged, a second phase has been added to show conditions after the removal
of the sediment trap.
j. Paved construction entrance (PCE) detail
Acknowledged, this is not required as disturbed area is less than 3 acres. We
considered specifying a PCE; however, the front yard conditions are not suited for
this type of entrance.

k. Fill sequence, final stabilization notes
Acknowledged, the sequence of construction has been updated. Please see Sheet C2
under "Management Strategy and Sequence of Construction."
1. Site -specific trap profile
Acknowledged, a site -specific trap profile has been provided on Sheet C3.
m. Label floor dimensions
Acknowledged, floor dimensions are now labeled. Please see Sheet C3.
n. Clarify TW /BW symbols (traps have embankments, not walls —TW /BW may confuse)
Acknowledged, TW/BW were added to the Soil Erosion & Sediment Control
Symbols legend on Sheet C3.
o. Typical ESC measure (VESCH) details
Acknowledged, the details are provided on Sheet C5.
p. Show /label Laurel Cove Road
Acknowledged, Laurel Cove Road is now labeled. Please see Sheet C3 & C4.
q. Show /label critical slopes
Acknowledged, the critical slopes are now shown and labeled. Please see Sheet C3 &
C4.
r. Label PCE
Acknowledged, this is not required as disturbed area is less than 3 acres. We
considered specifying a PCE; however, the front yard conditions are not suited for
this type of entrance. Thus, the construction entrance has been kept labeled as CE,
with the detail that matches it.
s. ESC Plan bond estimate request at earliest convenience
Acknowledged.
t. Bond estimate request
form:http://www.albemarle.org/upload/images/forms center/departments/Community_D
evelopment/forms/bonds/Bond_ Request_ to Establish_ a_Bond.pdf
Acknowledged, a bond estimate request will be provided separately.
u. Bond is required to be posted by property owner (Byers —ref. ordinance)
Acknowledged.
v. Include all text at 18-5.1.28.a./b. on the ESC Plan, since activity is a permanent fill
operation
Acknowledged, all text at 18-5.1.28 a./b. has been included on Sheet Cl under
"BORROW, FILL, AND WASTE AREA NOTES -SEC 18-5.1.28. A./B."
12. If this is an off -site stockpile for temporary storage of site material that will be returned to the
project site, an Amendment is appropriate.
Acknowledged, this is not a temporary off -site stockpile, this is a permeant fill, therefore, an
amendment is not appropriate per the comment.

13. This does not appear to be the case as site is graded level for a hotel, and does not require
exported material to be re -imported to the site.
Acknowledged.
