RE: Old Trail Block 10 WP0201600009 Amendment #3 — WPO Plan Amendment Review —
Comment Response Letter
Dear Mr. Anderson:
We have reviewed all of your comments from March 15, 2022 and made the necessary
revisions. Please find our responses to the comments below in bold lettering.
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.
SWPPP
1. Please ensure SWPPP (VAR100043) is on -site, but please note: If East Village LLC is not
subsidiary to March Mountain Properties (i.e., does not hold an active VAR10 permit),
then a VAR10 and SWPPP for East Village LLC OTV block 10 is required. Please clarify
East Village LLC status relative to March Mountain Properties.
VAR100043 is on -site. East Village LLC is a subsidiary to March Mountain Properties.
2. If a new VAR10 is required, please submit SWPPP using county template located at:
https://www.albemarle.org/home/showpublisheddocument/166/63720231032753000
a. Sec. 1: Registration Statement; please complete. Feel free to call if any
questions.
b. Sec. 6.A.: PPP Exhibit: Please show initial location of:
i. Rain gauge.
ii. Portable sanitary facilities (porta-john), as required.
iii. Covered non -hazardous waste dumpster, if required.
ENGINEERING I DESIGN I TECHNOLOGY
iv. Vehicle wash waters, draining to trapping measure (Not a sediment
trap design, per se, but shallow depression —1-2 backhoe buckets.
Avoid direct drainage to Ex. storm system, or pond/s.)
V. Concrete wash -out.
vi. On -site fuel, if required.
vii. Paint, stucco, chemical storage, if required.
c. Sec. 6E: List named individual responsible for PPP measures.
d. Sec. 8: Although county personnel will inspect, Applicant is required to retain
qualified (contractor/third-party) E&S inspection personnel to perform ESC
inspections and evaluate compliance relative to VESCH, 3rd Edition, 1992.
e. Sec. 9: Ensure Signed Certification is signed and dated.
A new VAR10 is not required. Project is approved and permitted under
current VAR100043.
B. Pollution Prevention Plan (PPP) —see SWPPP item 2.1b., above
The PPP content requirements can be found in County Code section 17-404.
C. Stormwater Management Plan (SWMP)
VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or
disapprove a SWMP. This plan is disapproved for reasons listed below. The stormwater
management plan content requirements can be found in County Code section 17-403.
1. VAR100043 covers most Old Trail Village Development. Please confirm whether East
Village LLC is subsidiary to March Mountain so Albemarle may determine whether
this Plan Amendment requires a separate VAR10 and separate WPO, or is covered
under VAR100043, with Amendment to WPO201600009 a possibility. It is not
immediately apparent what the case may be.
VAR100043 is on -site. East Village LLC is a subsidiary to March Mountain
Properties.
2. C0.0: Please revise plan title to include 'Amendment #3'.
The title has been revised to include 'Amendment #3'.
3. C2.0: Ensure easement plat vacates or establishes new easements, as outlined.
Easement plat will be submitted under separate cover.
4. C4.0: Provide North arrow.
A North arrow has been provided for Sheet C4.0.
5. C6.1: 9.005' spread, inlet Str. 202, throat length 6', does not impede travel lane, but
nearly entirely occupies parallel parking space width; in interest of safety and
convenience, Engineering recommends slightly longer throat length for this inlet.
Comment may repeat with Road plan review comments.
The layout has been revised and the inlet has been upsized.
6. Please remove C8.0 (please ensure sight distance profile is included with the road
plan).
Sheet has been removed.
7. Recent email correspondence discussed requirements for 4 subdivided lots east of
Rowcross St. Engineering recommends represent land disturbance associated with
4-lot subdivision with this Amendment, but developer may wish to pursue VSMP
/WPO permit coverage separately, under a separate WPO. Advantages applying now
are several:
a. Relatively straight -forward approval.
b. Quicker WPO approval for subdivided lots (subdivision also requires plat).
c. No new VAR10 permit for subdivided lots (if covered under VAR100043).
d. Please note this comment is affected by item CA., above.
East Village LLC is a subsidiary to March Mountain Properties and this area is
covered under VAR100043.
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 disapproved for reasons listed, below. The erosion control plan
content requirements can be found in County Code section 17-402.
1. C3.1: Limits of silt fence ambiguous; please include linework that delineates SF.
Line work for the silt fence for phase 1 has been provided on Sheet C3.1
2. C3.2: It appears that SF should persist in ESC Phase 2; please clarify, or provide SF.
SF does remain for Phase 2. Additional linework and call -outs have been added to
indicate as such.
We have included PDF copies of the plans and calculations for your review. If you have any
questions or comments, please feel free to give me a call at 434.295.5624 or email at
