layout sheet shows roll-top curb.
Curb detail has been updated and clarified in sheet CIA.
Rev. 1): Comment addressed.
3. [Sheet C2.0] There should bean existing SWM facility easement around L-1. Please show
the easement and the DB & PG.
No easement has been found in record.
Rev. 1): Response said there is no easement, however, is there a SWM agreement? If
so, please provide DB & PG.
This pond is included in several SWM agreements over the course of the development.
Facility L-1 is predominantly covered under agreements for Blocks 28 & 29B
development (DB4552 PG112) and the Block 1 Phase B and Block 3 Phase C
development (DB4565 PG 405).
4. Please provide spot shots to show how the water will drain near the Orion Lane and
Fennel Road intersection.
Spot shots have been added to the intersections for clarify.
Rev. 1): Comment addressed.
ENGINEERING I DESIGN I TECHNOLOGY
5. Ensure that all horizontal curve information is labeled on the plan (not just radii).
Horizontal curve information has been added to sheet C8.0. See line and curve table.
Rev. 1 : Comment addressed.
6. Please show all applicable pavement markings and road signs (names, stop, no parking).
Acknowledged.
Rev. 1 : Comment addressed.
7. Show CG-12 ramps.
CG-12 ramps are shown on C4.0 Layout Plan.
Rev. 1 : Comment addressed.
8. Sidewalk appears to stop along Orion Road. Per the cross section on Sheet C1.1, it
appears to be the full length of the road.
A waiver will be pursued for the elimination of sidewalk in this location.
Rev. 1 : Comment letter said waiver was being pursued to remove sidewalk but plan
still showed sidewalk. Did you mean waiver for the planting strip? Please clarify.
The sidewalk and planting strip has been revised along Orion Lane on this submission.
Please see C4.0 for updated layout.
9. Trees outside of the right-of-way will need to be in an easement with a maintenance
agreement.
Acknowledged. An easement sheet has been added for clarity and will be addressed
on the subdivision plat.
Rev. 1 : Comment addressed.
10. Please show the existing managed slopes on the plan.
Managed slopes are shown on sheet C4.0.
Rev. 1 : Comment addressed.
11. Drainage easement for the outfall must be public because it is draining some water from
a public road.
The easement language has been revised to be public.
Rev. 1 : Public easement only needed from structure 306 and on.
Easement has been revised. Please see sheet C4.1.
12. Sight distance easements appear to be necessary where sight lines are outside of the
right-of-way.
Acknowledged. An easement sheet has been added for clarity and will be addressed
on the subdivision plat.
Rev. 1 : Comment addressed.
13. Rev. 1 : Sidewalk along Fennel Road should be in the right-of-way.
The sidewalk along Fennel Road that connects to the walking trail, Lindy Bain Loop,
will be in a private easement per sheet C4.1 and is to be maintained by the HOA.
Planning (Andy Reitelbach) CRL dated 10-06-2021:
1. Sidewalk and planting strip must be provided along the entire lengths of both Orion
Lane and Oldham Drive, as these are public streets. These features are not currently
shown along Lot 47 for Orion Lane, or along the greenspace and Lot 56 for Oldham
Drive.
Oldham Drive was approved as an alley under SUB201700092 and SUB201800012
which does not contain any sidewalk or planting strips. Orion sidewalk has been
added accordingly.
Rev. 1 : A planting strip must still be provided along Orion Lane adjacent to Lot 47.
The layout has been revised accordingly.
2. The sidewalk along the fronts of Lots 47-56 must be 5 feet in width.
Sidewalk width has been updated to 5 feet.
Rev. 1 : Comment addressed.
3. Is the sidewalk along Lot 40 that connects to the trail proposed to be in the right-of-way
or in the lot? Appropriate easements will be required.
Outside ROW but in and easement
Rev. 1 : Provide the deed book and page number of the easement. If there is no
currently one, then an easement (and any related maintenance agreements) will need
to be recorded prior to approval of site plan/subdivision plat.
Acknowledged. The sidewalk will be within the private easement and will be
maintained by the HOA.
4. Provide accessible ramps with the sidewalks. These must be provided at the street
intersections.
CG-12 accessible ramps have been provided at street intersections.
Rev. 1 : There does not appear to be a CG-12 ramp provided opposite the existing one
on the corner of Orion Lane and Golf View Drive.
There is an existing receiving CG-12 on the south corner of Golf View Drive and Orion
Lane, and a CG-12 is proposed on the north corner of Golf View Drive and Orion Lane.
Additionally, a receiving CG-12 is proposed for the crossing of Orion Lane to the
community Open Space from this corner.
S. As the sidewalk and planting strip along Old Trail Drive is depicted outside of the right-
of-way, it must have an access easement placed over it. Easements will be required for
any sidewalks and planting strips that are outside of the right-of-way.
Acknowledged. An easement sheet has been added for clarity and will be addressed
on the subdivision plat.
Rev. 1 : Response acknowledged. Easements (and any related maintenance
agreements) must be recorded prior to approval of site plan/subdivision plat.
Acknowledge.
6. Revise the landscaping plan:
a. Street trees must also be provided in the planting strips along Oldham Drive and
Old Trail Drive.
Oldham Drive was approved as an alley under SUB201700092 and
SUB201800012 which does not contain any sidewalk or planting strips. In
addition, Old Trail Drive was originally approved without street trees. The
developer has added them along Old Trail Drive as development continues.
Please contact Dave Brockman regarding any questions on prior approvals.
Rev. 1 : With site plan review now occurring along this section of Old Trail Drive,
street trees will need to be provided at this time.
Street trees have been shown along Old Trail Drive.
b. Street trees should not be located in private lots. Any street trees that do remain
on private lots must have landscaping easements provided for their continued
maintenance.
Due to the nature of density within this block, trees need placed within lots
like Block 22. Any trees on private lots will be within an easement such as
Block 22 as well.
Rev. 1 : Response acknowledged. It is always preferred that street trees are
located in the public right-of-way. If, however, some trees are situated in the
public right-of-way, they will need to be located within an easement (with
appropriate maintenance agreements) prior to approval of the site
plan/subdivision plat.
Acknowledged, trees are located inside the ROW where possible. Trees outside
the public ROW are placed within landscape easements. Please see C4.1.
7. New Advisory Comment: With 30 attached units proposed, there must be eight (8) guest
parking spaces. These spaces must be provided in common areas (either designated on -
street parking spaces or in common bays), not included within either private driveways
or private garages. Although this comment is more for the review of the site plan, it may
affect the layout of the roads and rights -of -way.
Street parking is available near the intersection of Orion Lane and Oldham Drive.
Additionally, parking is available on the north side of Golf View Drive. Although
parking will not be striped on site, I have highlighted the spaces that can
accommodate (8) guest spaces below for clarification.

VDOT (Adam Moore):
1. In Mr. Fox's comment response letter dated 23 August 2021, he indicated he wanted to
allow parking on one side of Orion Ln Ext. The spacing of driveways and intersections
will prevent parking on the west side of the street, and the "No Parking" signs (added
with this revision) will prevent parking on the other side. As designed, there will be no
parking on Orion Ln Ext.
Street parking is available near the intersection of Orion Lane and Oldham Drive.
Additionally, parking is available on the north side of Golf View Drive. Although
parking will not be striped on site, I have highlighted the spaces that can

All traffic on private streets must stop before entering a public street. This includes
traffic on Fennel Rd crossing Orion Ln Ext through the intersection at the north end of
the subdivision. Please add "Stop" signs to show this.
"Stop" signs have been added.
3. The proposed sidewalks parallel to Oldham Dr is outside of the right-of-way. This
sidewalk will not be maintained by VDOT unless a right-of-way dedication is made that
includes this sidewalk in the Oldham Dr right-of-way.
The sidewalk will be maintained by the HOA.
4. Note that the final plan must show conformance with the VDOT Road Design Manual
Appendices B(1) and F, as well as any other applicable standards, regulations, or other
requirements.
Acknowledged.
Fire Rescue (Howard Logamarsino) 10-07-2021:
1. Rev. 1 : Your response correspondence shows you increased the width of Fennel Road
to 26 ft. to accommodate building height issues and Orion Lane as 30 ft fc/fc. The
submitted plans with seal dated 08/20/2021 show Fennel as 20 ft wide and Orion as 26
ft wide. Please clarify, correct as appropriate.
The plan has been revised. Orion Lane is 30-feet wide FC-FC, and Fennel is 26-feet
wide FC-FC. The no parking along either side of Fennel accommodates a clear 26'
travel way for fire and no parking along the new portion of Orion Lane also
accommodates a clear 26' travel way for fire.
2. Thank you for providing the no parking signs to delineate the no parking areas to ensure
obstructions to the required fire apparatus road width does not occur, however, in light
of comment #1, clarification of the issues brought out in comment #1 affect the need
for and the placement of these signs. After addressing comment #1, please ensure the
not parking signs are arranged appropriately (where road is too narrow to allow parking
on both sides, no parking signs are required where parking is to be limited to prevent
fire apparatus access road width obstruction).
Acknowledged. The no -parking signs remain as needed where proposed.
3. Based on the calculated ISO fire flow, the hydrant spacing required is no more than 500
feet between hydrants and arranged so that no structure is more than 250 feet from a
hydrant. On the plans with a seal date of 08/20/2021, the units on Fennel Road, near
the dead end, exceed this. Your response correspondence indicates adding a hydrant at
the end of Fennel, but I am not finding it on these plans. A hydrant at the dead end of
Fennel fulfills the requirement, a more practical location for fire operations is the corner
of Fennel Rd and Orion. If it must go at the dead end of Fennel, placing it at or before
the turn is preferred.
A fire hydrant has been proposed at the end Fennel.
4. Hydrant on Orion lane at Golf View is several feet off the road, across what appears to
be a grass/planting strip and sidewalk. Landscaping will obstruct this hydrant, make it
difficult to find and impractical to operate. Moving the hydrant closer to the curb is
more practical and will eliminate any question of its suitability for consideration as
meeting the requirements of the code.
The hydrant has been moved.
ACSA (Jeremy Lynn) 10-07-2021:
Sheet C0.0:
1. Flow Acceptance required from the RWSA. Provide anticipated schedule for full build -
out of this block. This request will need to be made by the ACSA.
Acknowledged.
2. Completion of One -Year Warranty items for Old Trail Village Block 32 Off -Site Waterline
required prior to final approval.
Acknowledged. Per zoom discussion with J Lynn on 10/25/21 warranty items outside of areas
within the final pavement will be fixed. All items that are affected by final paving will be
completed in the spring during final coat.
3. Recordation of Deed of Easement and Plat required for Old Trail Village Block 32
required prior to final approval.
Acknowledged. Per zoom discussion with J Lynn on 10/25/21, as-builts are being updated as
AG Dillard completes last utilities within Block 32 and will be submitted asap to get the deed
of easement recorded.
4. ACSA now requires the recordation of a Deed of Easement for on -site utilities prior to
the release of the first water meter.
Acknowledged. Per zoom discussion with J Lynn on 10/25/21, as-builts are being
updated as AG Dillard completes last utilities within Block 32 and will be submitted
asap to get the deed of easement recorded.
Sheet C1.0:
1. Provide updated ACSA General Water & Sewer Conditions.
Notes have been updated.
Sheet C1.2:
1. Remove Large Meter Service Line detail.
Detail has been removed from this submission.
2. Remove Typical Meter Vault (1 %" Meter) detail.
Detail has been removed from this submission.
3. Remove Typical Meter Vault detail.
Detail has been removed from this submission.
4. Provide updated Typical Service Lateral Installation detail.
Detail has been updated.
Sheet C2.0:
1. Clearly indicate removal of existing manholes.
Labels have been revised to indicate 'remove' as opposed to reading 'relocate'.
2. Clarify if the existing sanitary sewer will be removed or abandoned in place. If
abandoned in place, flowable fill required.
Labels have been added for clarity.
Sheet C5.0:
1. Connection cannot be made at the existing 12" x 12" tee at the intersection of Golf View
Drive and Orion Lane. Shift to the east and show connection with 12" x 8" TS&V.
Plan has been revised accordingly.
2. Consider shifting the water main along Orion Lane to the opposite side of the roadway
to shorten the length of water services. Be sure 10 feet of horizontal separation with the
sanitary sewer is maintained.
The watermain cannot be moved due to inadequate horizontal spacing and to ensure the
watermain does not follow along the road centerline.
3. Relocate FH along Orion Lane to the front side of the sidewalk. It may be appropriate to
cut the existing water main and reduce for the valve and fire hydrant.
FHA has been relocated.
4. Double taps can be utilized for single family attached lots.
Revisions have been made.
5. Consider placement of a fire hydrant at the end of Fennel Road to ensure adequate fire
protection. Maximum fire hydrant spacing is 500 feet.
A fire hydrant has been added to the end of Fennel Road.
6. The ACSA is unwilling to allow the use of the existing storm sewer to serve as the casing
pipe for the water main crossing under Old Trail Drive. The most appropriate alignment
seems to be a crossing of Old Trail Drive north of Lot 39 off the end of Fennel Road.
Show water connection over to the existing 12-inch diameter water main on the east
side of Old Trail Drive.
Water connection has been revised.
7. Provide lot numbers on Utility Plan Sheet.
Lot numbers have been added.
8. Sewer design revisions at the intersection of Fennel Road and Orion Lane. The sanitary
sewer between MH's 2 and 3 is too close to the units. Therefore, an additional manhole
should be placed just upstream of MH Ex. 1 and then shift MH 3 into the strip between
the curb and the sidewalk.
Sanitary sewer has been revised.
9. Sewer lateral for Lot 30 shall connect into exiting manhole.
Lateral has been moved.
10. Label existing manhole at the intersection of Orion Lane as OldTrIVil-23-1. This manhole
will likely need to be replaced due to revised pipe angle leaving manhole.
The label has been updated.
11. Label existing manhole along Fennel Road as OldTrIVil-37-1. This manhole will likely
need to be replaced due to revised pipe angle leaving manhole.
The label has been updated.
Sheet C6.1:
1. Eliminate this sheet from the ACSA's submittal.
Sheet has been removed from submittal package.
Sheet C7.1:
1. Sanitary sewer between MH's 3 and Ex. shall be ductile iron.
Pipe label has been changed to ductile iron.
2. Update existing invert elevations:
a. Upper Existing MH Invert Out —670.29'.
b. Lower Existing MH Invert In — 668.74'
The inverts of the pipes shown on the plans have been field verified on NAV83 datum
by Timmons Group surveying. Please advise on the discrepancy noted on inverts.
Sheet C9.1:
1. Eliminate this sheet from the ACSA's submittal.
Sheet has been removed from submittal package.
.Sheet L1.0:
1. Revise street tree locations to achieve 10 feet of horizontal separation with ACSA
utilities.
Street tree location have been revised to provide horizontal separation.
GIS (Elise Keiwra):
1. Rev. 1): Per site plan dated 04/26/2021, Orion Lane is existing road, please update and
pages that say Orion Lane Extended to Orion Lane.
Acknowledged. Name has been changed to remain "Orion Lane". Plan has been
revised.
ARB (Margaret Maliszewski):
1. Rev. 1): No objection. The ARB determined that ARB review/approval of this portion of
the development is not required.
