Bohler Engineering is pleased to submit on behalf of Shamin Hotels, the 41h Submission Virginia
Stormwater Management Plan for the Hampton Inn project in Albemarle, Virginia. The following
is our comment response letter addressing comments received from your department dated
September 25, 2020. Each comment is addressed and responded to as follows:
A. Stormwater Pollution Prevention Plan (SWPPP)
The SWPPP content requirements can be found in County Code section 17-405. A SWPPP
must contain (1) a PPP, (2) an ESCP, (3) a SWMP, and (4) any TMDL measures necessary.
Comment 2: Provide the Notice of Permit Coverage, once issued. (Rev. 2, 3) Comment
persists.
Response 2: Acknowledged. Notice of Permit coverage will be provided once issued.
B. Pollution Prevention Plan (PPP)
The PPP content requirements can be found in County Code section 17-404. This plan is
disapproved.
Comment 6: Section 8: Qualified Personnel must be identified prior to Grading Permit
issuance. (VSMP /WPO Plan must be approved prior to approval of the Final
Site Plan /FSP.) (Rev. 2) Comment persists. Applicant response:
'Acknowledged.' (Rev. 3) Persists. Applicant response (8/20/20 letter): 'Qualified
personnel shall be identified prior to Grading Permit issuance.'
Response 6: The Qualified Personnel will be identified once determined by the
developer.

Comment 8: Section 10: The Delegation of Authority should be provided prior to Grading
Permit issuance. (Rev. 2) Comment persists. Applicant response:
'Acknowledged.' (Rev. 3) Persists. Applicant: 'The Delegation of Authority will be
determined prior to Grading Permit issuance.'
Response 8: The Delegation of Authority will be identified once determined by the
developer.
C. Stormwater Management Plan (SWMP)
VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a
SWMP. This plan is disapproved. The stormwater management plan content requirements can
be found in County Code section 17-403. Note items 1, 3, below, this section, then skip this
section (since comments addressed, or if they persist, are required to be met prior to Grading
Permit issuance, not VSMP /WPO plan approval) and go to Sec. D. Erosion and Sediment
Control Plan since several comments there more nearly pertain to the SWM Plan than the ESC
Plan. Please address items 9, 12, 13 (Sec. D.) for SWM Plan and VSMP /WPO plan approval.
Comment 1: (Rev. 3) Comment revised to read: Nutrient credits must be purchased prior to
Grading Permit issuance, but purchase is not required for VSMP plan approval.
Response 1: Acknowledged.
Comment 3: Coordinate a stormwater control maintenance agreement with Ana Kilmer as
soon as possible. Agreement is required under 17-415, and is prerequisite to
both Grading Permit and FSP approval. (Rev. 2) Comment persists. Applicant
response: 'Acknowledged.' (Rev. 3) Persists. Applicant: 'The Stormwater Control
Maintenance Agreement shall be coordinated prior to final plan approval.' As
follow-up: Engineering encourages coordination as soon as possible since
Maintenance Agreement must be recorded prior to easement plat approval, and
easement plat approval is required prior to VSMP /WPO plan approval.
Response 3: Client is coordinating directly with the County on the Stormwater Control
Maintenance Agreement.
D. Erosion and Sediment Control Plan (ESCP)
Virginia Code §62.1-44.15:55 requires the VESCP authority to approve or disapprove an ESCP.
This plan is approved, yet review comments listed in this section with prior reviews relate to
SWM plan more than the ESC plan, and several persist. Please note items 9, 12, 13, below,
and address for SWM Plan and VSMP /WPO plan approval.
Comment 9: Note: PE -sealed geotechnical retaining wall design is required for Site Plan
approval. (Rev. 2) Comment persists. Applicant response: 'Acknowledged. PE -
sealed geotechnical retaining wall designs will be provided prior to Site Plan
approval.' (Rev. 3) Partially addressed. As follow-up: Hillis -Carnes Engineering
Associates retaining wall design titled Hampton Inn Charlottesville, d. 8/12/20 (10
sheets) indicate at least at one location along each of four (4) walls, labeled
Walls 1, 2, 3, 4, where wall ht. from base of wall (proposed grade) to top of wall
exceeds maximum ht. allowed for retaining walls located on managed steep
slopes. Max. ht. does not exceed max. allowable (wall) ht. by much, but each
wall appears to; for example:
a. Wall 1, Sta. 1+20; 10-block ht., or-7.33' ht.
b. Wall 2, Sta. 0+80; 10-block ht., or —7.33' ht.

c. Wall 3, Sta. 0+90; 9-block ht., or -6.66' ht.
d. Wall 4, Sta. 1+10; 10-block ht., or -7.33' ht.
Note: Height in excess of 6' could, as an option, be addressed with a 5 th
wall, which itself may not exceed 6' max. ht. if located on managed steep
slopes. Revise design to ensure max. wall ht. of each stepped retaining wall
located on managed steep slopes does not exceed 6'.
Response 9: The wall design has been revised to ensure all heights are below 6 feet and
provided with this submission.
Comment 12: Submit easement plat application for items listed at 10 and 11, above. Ensure
easement width for detention system conforms with drainage easement diagram
at ACDSM, p. 15; link to Design Manual: (Rev. 2) Comment persists. Applicant
response: 'An easement plat will be provided prior to plan approval.'

development/forms/design - stand ards_manual/Albemarle_Cou nty_Desig n_Stand

shall be submitted under separate cover.'
Response 12:The Easement Plat has been revised and resubmitted.
Comment 13: Note: Recorded deed of easement (deed /plat) is required prior to VSMP /WPO
plan approval. (Rev. 2) Comment persists. Applicant response: 'Acknowledged.

Persists.
Response 13:Acknowledged. The easement plat has been submitted and will be recorded
prior to plan approval.
Please note: Only a few items required for VSMP plan approval, but these are critical:
Comment 1: Max. retaining wall ht. ( Hillis -Carnes retaining wall design)
Response 1: The wall design has been revised to ensure all heights are below 6 feet and
provided with this submission.
Comment 2: Easement plat recordation. SWIM facility /public drainage
