Engineering, 3/24/2021 10:03 PM. Though not addressed, less critical since digital Approval identifies as
WPO202000030.
2. Ensure final site plan and WPO plan sets are consistent. (Rev. 1) Addressed.
3. Notes: (Rev. 1) Persist /Applicant acknowledges.
a. Since there is no subdivision, WPO plan approval requires SWM Facility (dry retention basin) and
SWM Facility Access easements be recorded prior to WPO plan approval. (Rev. 2) Addressed.
Easement recorded 3/23/21.
b. WPO plan approval is required prior to Site Plan approval. (Rev. 2) Addressed, plan approved.
4. Revise p. 18, Cale, packet to show and identify approximate location of 1% limit of analysis. Also, please
report V2-y. within Ex. 15" CMP at 12.78cfs. CMP is likely less resistant to erosion than concrete pipe.

6. Include Attached.PDF document, VSMH, Ch. 9, July 2013, 9-C.8.0 Permeable Pavement: O&M Checklist
on the plans. (Rev. 1) Addressed.
7. Include visual inspection findings of condition of existing on -site pipe systems. Any existing on -site pipe
system proposed to be integrated with post -developed storm conveyance requires visual verification and
photographs of bottoms of pipe. CMP typically weathers and is subject to corrosion which may completely
consume the floor of corrugated metal pipe. Condition of pipe must be rated good or better, without visible
gaps, pipe penetration, deformation, loss of capacity, etc., for existing pipes to be approved as part of post -
developed storm conveyance system proposed with this WPO plan. (Rev. 1) Withdrawn. Applicant: `The
existing on -site pipe system is now disconnected from the proposed improvements and left unchanged.
The storm sewer design routes to a new pipe that connects to the existing structure at Ivy Road.'
8. Please see Engineering final site plan review comments d. 6/10/20 (SDP202000044). Site plan review
comments that bear on storm conveyance should be addressed with subsequent WPO and site plans. (Rev.
1) Addressed. Applicant: `The Engineering final site plan review comments are incorporated in this
revision of the WPO set.'
9. Please include table of contents to index sections of 41-p. Calculation packet. (Rev. 1) Addressed.
10. Confirm Calculation packet includes and reflects offsite storm runoff that enters and transits site via pipe
beneath CSX Transportation RR tracks. Make explicit reference to off -site runoff Revise calculations or
SWM facility design, as needed. (Rev. 1) Addressed. Applicant: `Offsite runoff conveyed from beneath

the CSX railroad tracks is now included as off -site runoff in the plan set. Calculations have been updated
for this drainage.' [Image with initial comments removed with Rev. 1 comments.]
D. Erosion and Sediment Control Plan (ESCP) - Approved
Virginia Code §62.1-44.15:55 requires the VESCP authority to approve or disapprove an ESCP. This plan
is approved.
1. Sheet 3, ESC Notes and Narrative, project description lists dates (years /months) that appear inconsistent
with anticipated completion within 6 months. Timeline appears to approach 15 months. Please revise
description for internal consistency. Please describe commercial redevelopment, along with parking and
circulation improvements. Please list 2.52 Ac. LOD using black text (more easily readable than grayscale),
(Rev. 1) Addressed.
2. Sheet 3: Include Sec. 8.1. of VA DEQ Stormwater Desien Specification No. 7 on the ESC Plan. Link:

PAVEMENT vl-8 0301201 Lod f (Rev. 1) Addressed.
Sheet 4
3. Show /label existing contours at 1' intervals, or interval sufficient to evaluate direction of flow during
phase 1 development. (Rev. 1) Addressed,
4. Provide spot elevations along proposed diversion dike west of 2415 building. County GIS appears to
indicate elevation gain as diversion leads north to the back side of the site, crossing a higher contour.
[Image with initial comments removed with Rev. 1 comments.] (Rev. 1) Addressed.
5. Make Phase I ESC measure symbols dark text, for example: IP at DI to be lowered from 560.7 to 560.4,
which leads to pipe labeled `Existing storm shall remain to convey sediment trap outflow.' (Rev. 1)
Addressed,
6. Recommend notes and linework preserve a portion of existing pavement to be removed to serve as
temporary paved construction entrance. It seems intuitive to make use of existing pavement at edge of U.S.
Rt. 250 as a paved construction entrance. Engineering is not opposed to this. (Rev. 1) Addressed.
7. Provide spot shot elevations that indicate grade change that occurs to decrease area to STI and increase
area to ST2, between phase I and II. Clearly label ST drainage divides in Phase I, Phase II. (Rev. 1)
Addressed. Applicant: `ST 2, & ST 3 now maintain the same size through all three phases of the ESC plan.
STI has the same footprint in all phases, but the floor is lowered in phase III to accommodate the switch to
a pipe outfall. This is noted on the ESC Phase III plan. The drainage divides for phases I and II sediment
traps are now labeled.'
8. Provide SAF, especially in vicinity of U.S. Rt. 250. (Rev. 1) Addressed.
9. Coordinate SAF /other VDOT-approved barriers required to make improvements within U.S. Rt. 250 RW.
(Rev. 1) Addressed. Applicant: `SAF and other barriers are now utilized to make improvements within
Route 250, the MOT plan is included with the Final Site Plan with all required signage for the work within
the VDOT ROW.'
10. Obtain VDOT land use permit for activity within VDOT RW. (Rev. 1) Addressed. Applicant: `VDOT
permit activity will be obtained for the work within the ROW.'
11. To extent practical, provide pedestrian transit of site during as many phases of site development as is safe,
or practical. No pedestrian facilities exist within VDOT RW, nor do pedestrian facilities exist along EBL,
U.S. Rt. 250. The existing paved walk is internal to site, and there are phases of construction when it must
be closed, but may be times it may remain safely open for pedestrian use. (Rev. 1) Addressed. Applicant:
`Pedestrian access along Route 250 is now prioritized in the proposed construction timeline, see
construction timeline and note on sheet 4.'
12. Recommend revise Sheet 3 Notes to describe /define phases of construction during which existing paved
walk may remain open. Include Notes directing contractor to provide signs alerting pedestrians of
construction activity, risk /hazard, or No Trespassing. (Rev. 1) Addressed.
13. Provide SAF that corresponds with Ex. paved walk open or partially -open periods. Paved walk: image,
below. [Image with initial comments removed with Rev. 1 comments.] (Rev. 1) Partially addressed. As
follow up: Sheet 2 indicates existing asphalt path to be demolished, yet sheets 4-6 show existing sidewalk.
Engineering Review Comments
Page 4 of 5
Please confirm if asphalt path is to be demolished, and if so, please indicate type and width of walk that
will replace the asphalt path. Also, sheet 3, Sequence Note 16. (Rev. 2) Addressed.
14. Provide `Construction Ahead' signs on plans as needed for land disturbance or construction activity within
VDOT RW (water lateral replacement, for example). (Rev. 1) Addressed. Applicant: `A MOT plan is
provided with the Final Site Plan which includes the required construction waming signage for work within
the VDOT ROW.'
15. Location of construction parking /staging with CRS at SW comer of 2415 building appears unworkable.
Access to this location is obstructed on all sides (diversion dikes, ST2, Ex. tree to remain). Please revise.
(Rev. 1) Addressed.
16. Provide RW diversion at paved construction entrance (PCE)-U.S. Rt. 250 to limit amount of material that
tracks onto U.S. Rt. 250, Divert RWD runoff to a suitable trapping measure. Plan note indicates PCE with
onsite wash rack down gradient from WIN diversion but linework does not appear to indicate RWD.
Existing contours do not indicate where a wash rack might be located in a narrow, pre -developed space.
(Rev. 1) Addressed.
17. Label /identify feature between ST2 and existing inlet in parking lot. Define feature /purpose. (Rev. 1)
Addressed,
18. Sheet 5, 6: Label improvements (linework) between 2415 building and RWSA Ex. MIL (Rev. 1)
Addressed,
19. Sheet 4, 7: Recommend increase volume of STI, if possible. STI weir outlets to an Ex. MIL and thence to
existing piped conveyance along U.S. Rt. 250. This existing conveyance skirts U.S. 250 (either WBL or
EBL' path 1, 2, below) before daylighting to parallel U.S. 29 SBL on -ramp. A stream eventually winds and
enters a residential community, discharging to a pond. Any upset at 2415 Ivy Road will be visible in this
private residential community pond. CE is reminded of imperative to avoid off -site downstream impacts
during construction. Proposed wet and dry volumes of STI are just within specification. A high rainfall
event may lead to near -immediate visible off -site impact, complaints, and urgent need to respond. CLS
Imes [images removed with Rev. 1 comments]: (Rev. 1) Addressed. Applicant: `The volume of STI has
been increased with additional storage provided in excess of that required.'
Sheet 7
20. Provide ST design for smaller STI, ST3. STI, ST3 exist in larger and revised, smaller sizes. (Rev. 1)
Addressed. Applicant: `ST3 no longer changes size in the proposed plan. STI is made deeper in phase III
and will not be reduced to the size of the SWM facility until the site is stabilized and the pond can be
converted to a dry detention basin per the SWM plan.'
21. In each view of sediment traps, label floor dimensions. (Rev. 1) Partially addressed. As follow-up: Please
increase pitch of dimension labels, so readable, for example, ST# 1 (29', 99') [Image removed with Rev. 2
comments]: (Rev. 2) Addressed,
22. In each plan view label STI, ST2, ST3 outfall weir L x W x D. (Rev. 1) Addressed. Riprap dimensions
labelled in inset details.
Process:
After approval, plans will have to be bonded. The bonding process is begun by submitting a bond estimate request
form and fee to the Department of Community Development. One of the plan reviewers will prepare estimates and
check parcel and easement information based on the approved plans. [Final: WPO plan bond estimates complete,
3/24/21.] The County's Management Analyst will prepare bond agreement forms, which will have to be completed
by the owner and submitted along with cash, certificates or sureties for the amounts specified. [Final: in process.]
The agreements will have to be approved and signed by the County Attorney and County Engineer. This may take 2-
4 weeks to obtain all the correct signatures and forms.
Engineering Review Comments
Page 5 of 5
After bonding and agFeements aFe is complete, county staff will enter project information in a DEQ database for
state application processing. DEQ will review the application information based on local VSMP authority approval.
At this time, the DEQ portion of the application fees will have to be paid directly to the state. For fastest processing,
this is done electronically with the emails provided on the application. DEQ should notify applicants with
instructions on how to pay fees. When DEQ approves the application, they will issue a permit coverage letter. This
should be copied to the county.
After DEQ coverage is issued, via the coverage letter, the County can hold a pre -construction conference.
Applicants must complete the request for a pre -construction conference form, and pay the remainder of the
application fee. The form identifies the contractor and responsible land disturber, and the fee remaining to be paid.
This will be checked by county staff, and upon approval, a pre -construction conference will be scheduled with the
County inspector. At the pre -construction conference, should everything proceed satisfactorily, a joint VSMP and
grading permit will be issued by the County so that work may begin.
County forms can be found on the county website forms center under engineering,
